PROSPECTUS SUMMARY

        This summary highlights information contained elsewhere in this prospectus and does not contain all of the information that you should consider in making your investment decision. Before investing in our common stock, you should read this entire prospectus carefully, including the sections entitled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our financial statements and the related notes contained elsewhere in this prospectus. Unless the context otherwise requires, references in this prospectus to the "company," "NextCure," "we," "us" and "our" refer to NextCure, Inc.

Overview

        We are a clinical-stage biopharmaceutical company committed to discovering and developing novel, first-in-class immunomedicines to treat cancer and other immune-related diseases by restoring normal immune function. We view the immune system holistically and, rather than target one specific immune cell type, we focus on understanding biological pathways, the interactions of cells and the role each interaction plays in an immune response. Through our proprietary Functional, Integrated, NextCure Discovery in Immuno-Oncology, or FIND-IO, platform, we study various immune cells to discover and understand targets and structural components of immune cells and their functional impact in order to develop immunomedicines. We are focused on patients who do not respond to current therapies, patients whose cancer progresses despite treatment and patients with cancer types not adequately addressed by available therapies. We are committed to discovering and developing first-in-class immunomedicines, which are immunomedicines that use new or unique mechanisms of action to treat a medical condition, for these patients.

        Our lead product candidate, NC318, is a first-in-class immunomedicine targeting a novel immunomodulatory receptor called Siglec-15, or S15. In October 2018, we initiated a Phase 1/2 clinical trial of NC318 in patients with advanced or metastatic solid tumors. We completed enrollment of the Phase 1 portion of this trial in August 2019 and preliminary data will be presented at the Society for Immunotherapy of Cancer, or SITC, annual meeting in November 2019. We began enrolling patients in the Phase 2 portion of the trial in October 2019 and expect to announce initial data from the Phase 2 portion by the end of 2020. Our second product candidate, NC410, is a novel immunomedicine designed to block immune suppression mediated by an immune modulator called Leukocyte-Associated Immunoglobulin-like Receptor 1, or LAIR-1. We expect to submit an investigational new drug application, or IND, to the U.S. Food and Drug Administration, or FDA, for NC410 in the first quarter of 2020.

        Our approach to identifying targets for new immunomedicines is based on our FIND-IO platform. FIND-IO embodies a rational approach to the discovery of novel cell surface and secretory molecules that drive functional immune responses. We use our immunology knowledge, experience, capabilities and tools we have developed, including our FIND-IO platform, to support our discovery efforts. We are working to discover novel targets that play a key role in mediating immune dysfunction that allows tumors to evade the immune system. We are seeking to identify and develop immunomedicines that counteract these outcomes and to further validate and advance our product candidates. We have identified multiple novel targets using our FIND-IO platform, including those for which certain of our research programs are being designed to target. In addition, the immunosuppressive properties of S15, the target of NC318, were discovered using a predecessor of our FIND-IO platform.

        The advancement of cancer to late stages indicates a failure of the immune system to mount an effective anti-tumor immune response. Immuno-oncology, which focuses on stimulating the immune system to respond to cancer and includes checkpoint inhibitors targeting PD-L1, PD-1 and CTLA-4, is one of the most significant advances in the history of cancer treatment. In 2011, the first checkpoint inhibitor was approved, and today, despite only a modest breadth of efficacy, this class of therapies is estimated to have had global sales of more than $17 billion in 2018 and is predicted to reach more than $33 billion in global sales by 2022. However, despite the recent success of checkpoint inhibitors, efficacy has been

limited. It is estimated that up to 60% to 70% of cancer patients, including those with melanoma, renal cell cancer, colorectal cancer, non-small cell lung cancer, or NSCLC, urothelial cancer and head and neck squamous cell carcinoma, do not respond to single-agent therapy with checkpoint inhibitors. In addition, some patients develop resistance after initial treatment with these therapies. As a result, the standard of care in cancer today leaves many patients underserved. We believe broader efficacy and more meaningful clinical responses in oncology may be obtained by focusing on the tumor microenvironment, or TME.

        We are using our FIND-IO platform as our discovery engine to identify targets and develop immunomedicines that restore normal immune function in the TME through novel mechanisms of action. Since our founding in 2015, we have developed, industrialized and optimized our FIND-IO platform based on the immunological expertise of our management team and the scientific leadership of our scientific founder, Dr. Lieping Chen. Our approach in creating the FIND-IO platform, and how we apply it, reflects our belief in the importance of understanding biological pathways of all cells in the immune system and restoring normal immune function. The platform uses our proprietary approaches to assess the suppressive or stimulatory function of immune pathways in T cells and other immune cells, as measured by effects on proliferation or induction of molecules known to impact immune responses, such as cytokines, which are signaling molecules secreted by cells in the immune system that mediate and regulate immunity and inflammation. We study primary immune cells from healthy donors and from patients with various diseases, as well as established cell lines from immune and non-immune cell lineages, including T cell subsets, monocytes, macrophage subpopulations and cancer cell lines. In oncology, we are using the FIND-IO platform to discover immunomedicines with the potential to intervene or modulate interactions of immune cells within the TME to restore anti-tumor activity. We are also expanding the functional screening approach of our FIND-IO platform for the identification of novel targets in other serious illnesses outside of oncology, including autoimmune, inflammatory and neuro-inflammatory diseases.

        In November 2018, we entered into a multi-year collaboration agreement with Eli Lilly and Company, or Lilly, focused on the discovery and development of immunomedicines for oncology using our FIND-IO platform. The collaboration seeks to discover novel cancer targets utilizing our platform and provides that we and Lilly will each receive options to exclusively develop antibodies resulting from the collaboration. In connection with the agreement, we received an upfront payment of $25.0 million in cash and an equity investment of $15.0 million and are eligible to receive development and regulatory milestones and sales milestones in an aggregate of up to $1.4 billion, as well as royalty payments.

Our Pipeline

        We are leveraging our understanding of biological pathways and our FIND-IO platform to discover, validate and build a proprietary pipeline of immunomedicine candidates. The figure below details our pipeline of product candidates and principal discovery and research programs.

GRAPHIC

Our Programs

        NC318, our lead immunomedicine program, is a monoclonal antibody targeting S15, which is expressed on highly immunosuppressive cells called M2 macrophages and on tumor cells. The immunosuppressive properties of S15 were discovered in 2015 at Yale University by Dr. Chen. Dr. Chen was also the first to discover a molecule he called B7-H1, which is now more widely known as PD-L1, or programmed cell death protein ligand 1, which is the ligand for PD-1, or programmed cell death 1. In preclinical research, we and others observed that S15 promotes suppression of T cell proliferation and negatively regulates T cell function. NC318 is designed to block this S15-mediated immune suppression and restore T cell function and anti-tumor immunity in the TME, which we believe will reduce and kill tumors. We believe NC318 has the potential to treat multiple cancer indications because S15 is expressed in multiple tumor types and has a unique ability to modulate immune responses in the TME. In addition, because S15 and PD-L1 expression in tumors generally appear to be non-overlapping, we believe NC318 may be well suited to treat patients who are not responding to PD-1/PD-L1 directed cancer therapies.

        In preclinical studies, we evaluated the safety and efficacy of 5G12, the murine parent antibody of NC318, which has similar overall functional properties to NC318, and observed that blocking the effects of S15 with 5G12 restored immune function and anti-tumor immunity, reduced tumor growth and increased survival.

        Our ongoing first-in-human trial is an open-label, Phase 1/2 clinical trial designed to assess the safety and tolerability of NC318, to define the maximum tolerable dose or pharmacologically active dose and to assess preliminary efficacy. Patients receive NC318 on day one of each cycle. We initiated the trial with 14-day cycles; however, we may explore alternate doses and administration schedules depending on pharmacokinetics, pharmacodynamics, biomarker data, safety results and feedback from investigators. We designed this clinical trial with a robust biomarker strategy to help evaluate clinical activity throughout the

trial by focusing on markers of pharmacodynamics. We are initially evaluating NC318 for the treatment of advanced or metastatic solid tumors, including NSCLC, ovarian cancer, head and neck squamous cell carcinoma and triple-negative breast cancer, or TNBC.

        Enrollment of the Phase 1 portion of the trial was completed in August 2019 and preliminary data from the Phase 1 portion will be presented in November 2019 at the Society for Immunotherapy of Cancer, or SITC, annual meeting.

        We began enrolling patients in the Phase 2 portion of the Phase 1/2 clinical trial of NC318 in October 2019. The Phase 2 portion of the trial is an open-label trial designed to detect a relevant efficacy signal, or response rate, for each tumor type at a 400 mg dose administered every two weeks. In this portion, we will enroll up to 100 patients with tumor types that, based on tumor bank analyses, have been shown to have elevated S15 expression, including NSCLC, ovarian cancer, head and neck squamous cell carcinoma and TNBC. We expect to announce initial data from the Phase 2 portion of the trial by the end of 2020.

        In 2020, we intend to initiate a Phase 1/2 clinical trial to evaluate NC318 in combination with standard of care chemotherapies in patients with advanced or metastatic solid tumors. This trial will be an open-label trial conducted in two phases. The Phase 1 component will be designed to assess the safety and tolerability of NC318 in combination with at least two different chemotherapy regimens and to define the maximum tolerable dose of NC318 when administered with each chemotherapy. The Phase 2 component will be designed to assess preliminary efficacy of each combination in specific tumor types in a manner that can potentially support the use of such combinations in first-line therapies of advanced or metastatic solid tumors.

        NC410, our second immunomedicine program, is a fusion protein designed to block immune suppression mediated by LAIR-1. LAIR-1 is expressed on T cells and antigen-presenting cells, known as dendritic cells, that present tumor antigens to immune cells in order to generate immune responses. The binding of LAIR-1 to collagen or C1q results in loss of immune function in the TME and a reduction in T cell function and dendritic cell activity. By blocking the binding of LAIR-1, NC410 can promote T cell function and dendritic cell activity, which could result in anti-tumor immune responses that eliminate cancer cells.

        We have conducted multiple preclinical studies to assess the activity of NC410 across a variety of preclinical models. These studies support our understanding that eliminating or blocking the binding of LAIR-1 to collagen or C1q can restore normal immune function in multiple immune cells, including T cells and myeloid cells, resulting in activation of T cells and anti-tumor immunity. We and others have analyzed genomic and protein databases and observed that LAIR-1 expression levels negatively correlate with survival rates for several cancers, including brain, renal, colorectal, glioma, lung, urothelial and ovarian cancers. These analyses support possible targeting of these tumor types as primary indications for therapeutic treatment with NC410. We are currently conducting IND-enabling studies for NC410 and expect to submit an IND and initiate a Phase 1/2 clinical trial in patients with advanced or metastatic solid tumors in the first quarter of 2020. We are currently focused on opportunities for NC410 in ovarian cancer, NSCLC and renal cancer.

        In addition to NC318 and NC410, we are also pursuing discovery and preclinical evaluation of other potential novel immunomodulatory molecules. Among these is an antibody that targets a novel member of the B7-family of immunomodulatory proteins. We also have an antibody in preclinical development targeting an immune modulator that is highly expressed in inflamed tissue and the TME in multiple tumor types. In addition, based on our understanding of the LAIR pathway, including through our development of NC410, we are also pursuing monoclonal antibodies that target LAIR-1 and directly block LAIR-1 signaling to prevent tumor growth or to eliminate the tumor. These novel LAIR-1 antibodies have unique functional properties that may provide additional opportunities in both cancer and autoimmune disorders.

Our FIND-IO Discovery Engine

        Our FIND-IO platform is the result of our industrialization, expansion and optimization of a predecessor platform that Dr. Chen used to discover the immunosuppressive properties of S15. Our FIND-IO platform applies a function-based screening approach to identify human proteins and to determine whether those proteins alter or stop an immune response resulting in immune evasion. The platform is designed to identify novel cell surface molecular interactions that drive functional immune responses. Our FIND-IO platform broadly and quantitatively evaluates interactions between relevant protein components and different cellular types over time in order to identify novel targets that either increase or decrease immune-related functional responses associated with desired immune responses against tumors. By identifying novel immune modulators, proteins or other molecules through the FIND-IO platform, we aim to develop next-generation immunomedicines that restore normal immune function in the TME.

Our Strategy

        Our strategy is to use our fully integrated discovery and product development infrastructure to build a sustainable pipeline of product candidates to treat cancer patients who are not adequately served by currently available therapies. The key elements of our strategy include:

    Advancing the clinical development of our lead product candidates, NC318 and NC410.

    Building an oncology pipeline of novel targets for new immunomedicines focused on non-responders.

    Leveraging our fully integrated development, quality systems and cGMP manufacturing capabilities.

    Expanding our current focus and creating new opportunities outside of the oncology field, including through strategic partnerships.

Our Team

        We have assembled an experienced management team to execute on our mission to create novel immunomedicines. Our scientific founder and members of our management team collectively have extensive experience in drug discovery and product development and are leaders in the immuno-oncology field. Members of our management team have experience discovering, developing, manufacturing and commercializing biologics, including some of the earliest approved monoclonal antibodies, such as Synagis, as well as some of the first immune checkpoint inhibitor monoclonal antibodies and fusion proteins targeting the PD-1/PD-L1 pathway and CTLA-4, including Yervoy. Within three years, we advanced our company from formation to antibody generation to the clinic, and constructed a manufacturing facility that complies with cGMP and that we have used to manufacture our preclinical and clinical drug supply.

        Members of our management team have a longstanding relationship with our scientific founder Dr. Chen, who is the United Technologies Corporation Professor in Cancer Research and Professor of Immunobiology, of Dermatology and of Medicine (Medical Oncology) at Yale, and the Co-Director of the Cancer Immunology Program at Yale Cancer Center. Dr. Chen was the first to discover PD-L1 and to show that it is expressed by multiple tumor types and its activity can cause the death of T cells, preventing those T cells from eliminating cancer cells. He also showed that blocking the interaction between PD-1 and PD-L1 with monoclonal antibodies improved the immune system's ability to eliminate tumors. Dr. Chen's work provided an important foundation for the subsequent development of immunotherapies that enable more effective immune treatments against cancer. Since then, his laboratory has identified and characterized various molecules in two of the major families of immune modulating proteins, the B7-CD28 and the tumor necrosis factor receptor/ligand superfamilies, and elucidated their interactions and functions in controlling immune responses. The immunosuppressive properties of S15, the target of our lead product candidate, NC318, were discovered in Dr. Chen's lab using a predecessor of our FIND-IO platform. In

December 2015, we entered into a license agreement with Yale, pursuant to which we obtained an exclusive, royalty-bearing, sublicensable worldwide license to products that either incorporate certain licensed patents used in the discovery of targets or arise out of research and development of Dr. Chen's laboratory at Yale, including S15. We continue to collaborate with Dr. Chen on discovering novel immunomedicines through an exclusive sponsored research agreement with Yale.

        We believe the combination of our team's capabilities and focus on understanding the biological pathways of the immune system, our product development expertise and manufacturing infrastructure, our partnership with Lilly and our relationship with Dr. Chen and Yale positions us to build a sustainable portfolio of first-in-class immunomedicines.

Risks Associated with Our Business

        Our ability to implement our business strategy is subject to numerous risks and uncertainties. You should carefully consider all of the information set forth in this prospectus and, in particular, the information in the section entitled "Risk Factors" beginning on page 13 before making an investment decision. Risks include, among others, the following:

    We have a limited operating history and no products approved for commercial sale. We have a history of significant losses, expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability.

    Even with the expected net proceeds from this offering, we will require substantial additional financing to pursue our business objectives, which may not be available on acceptable terms, or at all. A failure to obtain this necessary capital when needed could force us to delay, limit, reduce or terminate our product development, commercial efforts or other operations.

    Our business is dependent on our ability to advance our current and future product candidates through clinical trials, obtain marketing approval and ultimately commercialize them.

    Our approach to the discovery and development of product candidates based on our FIND-IO platform is unproven and may not result in marketable products.

    Clinical development involves a lengthy and expensive process with uncertain outcomes. We may incur additional costs and experience delays in developing and commercializing or be unable to develop and commercialize our current and future product candidates.

    The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time-consuming and inherently unpredictable, and we may ultimately be unable to obtain regulatory approval for our product candidates.

    Positive results from preclinical studies and early-stage clinical trials may not be predictive of future results. Initial positive results in any of our clinical trials may not be indicative of results obtained when the trial is completed or in later stage trials.

    We are highly dependent on our key personnel, and if we are not successful in attracting, motivating and retaining highly qualified personnel, we may not be able to successfully implement our business strategy.

    Given our limited operating history, our manufacturing experience as an organization and with our manufacturing facility is limited.

    We have filed patent applications for our lead product candidates, but no patent has yet issued from these applications. If we are unable to obtain and maintain patent protection for our product candidates, or if the scope of the patent protection obtained is not sufficiently broad or robust, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize our product candidates may be adversely affected.

    We may depend on Lilly, Yale or other third-party collaborators for the discovery, development and commercialization of our current and future product candidates. If our collaborations are not successful, we may not be able to capitalize on the market potential of these product candidates.

    We face significant competition from other biotechnology and pharmaceutical companies, and our operating results will suffer if we fail to compete effectively.

        For additional information about the risks we face, see the section entitled "Risk Factors."

Corporate Information

        We were incorporated in Delaware in September 2015. Our primary executive offices are located at 9000 Virginia Manor Road, Suite 200, Beltsville, Maryland 20705 and our telephone number is (240) 399-4900. Our website address is www.nextcure.com. The information contained on, or that can be accessed through, our website is not part of this prospectus and should not be considered as part of this prospectus or in deciding whether to purchase our common stock.

        NextCure, FIND-IO and our logo are some of our trademarks used in this prospectus. This prospectus also includes trademarks, tradenames and service marks that are the property of other organizations. Solely for convenience, our trademarks and tradenames referred to in this prospectus may appear without the ® and ™ symbols, but those references are not intended to indicate, in any way, that we will not assert, to the fullest extent under applicable law, our rights or the right of the applicable licensor to these trademarks and tradenames.

Implications of Being an Emerging Growth Company and a Smaller Reporting Company

        We are an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and, as such, we have elected to comply with certain reduced public company reporting requirements for our filings, including this prospectus.

        For so long as we remain an emerging growth company, we are permitted and intend to rely on certain exemptions from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved. In particular, in this prospectus, we have provided only two years of audited financial statements and have not included all of the executive compensation related information that would be required if we were not an emerging growth company. Accordingly, the information contained herein may be different than the information you receive from other public companies in which you hold stock.

        We will remain an emerging growth company until the earliest of (i) December 31, 2024, (ii) the last day of the first fiscal year in which we have total annual gross revenues of at least $1.07 billion, (iii) the last day of the first fiscal year in which the market value of our common stock that is held by non-affiliates exceeds $700.0 million on June 30th and (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

        The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to delay the adoption of some accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of this extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the

JOBS act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

        We are also a "smaller reporting company" and will remain a smaller reporting company while either (i) the market value of our stock held by non-affiliates was less than $250 million as of the last business day of our most recently completed second fiscal quarter or (ii) our annual revenue was less than $100 million during our most recently completed fiscal year and the market value of our stock held by non-affiliates was less than $700 million as of the last business day of our most recently completed second fiscal quarter. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies, including many of the same exemptions from disclosure requirements as those that are available to emerging growth companies, such as reduced disclosure obligations regarding executive compensation in this prospectus and our periodic reports and proxy statements. For so long as we remain a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure and other requirements that are applicable to other public companies that are not smaller reporting companies.

RISK FACTORS

        Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below together with all of the other information in this prospectus, including our financial statements and the related notes and the information described in the section entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations," before deciding whether to invest in our common stock. If any of the events described below actually occurs, our business, results of operations, financial conditions, cash flows or prospects could be harmed. If that were to happen, the trading price of our common stock could decline, and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations.

Risks Related to Our Financial Position and Need for Additional Capital

We have a limited operating history and no products approved for commercial sale. We have a history of significant losses, expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability.

        We are a clinical-stage biopharmaceutical company with a limited operating history. Since our founding in 2015, we have incurred significant net losses. Our net losses were $22.8 million and $14.4 million for the year ended December 31, 2018 and the six months ended June 30, 2019, respectively. As of June 30, 2019, we had an accumulated deficit of $61.7 million. We have funded our operations to date primarily with proceeds from the sale of preferred stock, upfront fees received in connection with the Lilly agreement and proceeds from the sale of our common stock in connection with our initial public offering, or IPO. Since commencing operations, we have devoted substantially all of our efforts and financial resources to organizing and staffing our company, identifying business development opportunities, raising capital, securing intellectual property rights related to our product candidates, building and optimizing our manufacturing capabilities and conducting discovery, research and development activities for our product candidates, our discovery programs and our FIND-IO platform.

        We expect that it will be several years, if ever, before we have a commercialized product. We expect to continue to incur significant expenses and operating losses for the foreseeable future. The net losses we incur may fluctuate significantly from quarter to quarter. We anticipate that our expenses will increase substantially if, and as, we:

13


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

        To become and remain profitable, we, whether on our own or jointly with Lilly or any potential future collaborator, must develop and eventually commercialize products with significant market potential. This will require us to be successful in a range of challenging activities, including completing preclinical studies and clinical trials, obtaining marketing approval for product candidates, manufacturing, marketing and selling products and satisfying any post-marketing requirements. We may never succeed in any or all of these activities and, even if we do, we may never generate revenue that is significant or large enough to achieve profitability. If we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our company and could impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment.

We have never generated revenue from product sales and may never be profitable.

        Our ability to generate revenue from product sales and achieve profitability depends on our ability, alone or with our collaboration partners, to successfully complete the development of, and obtain the regulatory approvals necessary to commercialize, our product candidates. We do not anticipate generating revenue from product sales for the next several years, if ever. Our ability to generate future revenue from product sales depends heavily on our, or our existing or future collaborators', success in:

14


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

        We anticipate incurring significant costs associated with commercializing any product candidate that is approved for commercial sale. Our expenses could increase beyond expectations if we are required by the FDA or other regulatory agencies to perform clinical trials or studies in addition to those that we currently anticipate. Even if we are able to generate revenue from the sale of any approved products, we may not become profitable and may need to obtain additional funding to continue operations.

Even with the expected net proceeds from this offering, we will require substantial additional financing to pursue our business objectives, which may not be available on acceptable terms, or at all. A failure to obtain this necessary capital when needed could force us to delay, limit, reduce or terminate our product development, commercialization efforts or other operations.

        Our operations have consumed substantial amounts of cash since inception. We expect to continue to spend substantial amounts to continue the preclinical and clinical development of our current and future programs. If we receive marketing approval for any product candidates, including NC318 and NC410, we will require significant additional amounts of cash in order to launch and commercialize such product candidates. In addition, other unanticipated costs may arise. Because the designs and outcomes of our planned and anticipated clinical trials are highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development of and commercialize any product candidate we develop.

        Our future capital requirements depend on many factors, including:

        Until we can generate sufficient product and royalty revenue to finance our cash requirements, which we may never do, we expect to finance our future cash needs through a combination of public or private equity offerings, debt financings, marketing and distribution arrangements, other collaborations, strategic

alliances and licensing arrangements. As of June 30, 2019, we had $192.7 million in cash and cash equivalents. Based on our research and development plans, we expect that the net proceeds from this offering, together with our existing cash and cash equivalents, will enable us to fund our operating expenses and capital expenditure requirements into                . This estimate is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect. Changes may occur beyond our control that would cause us to consume our available capital before that time, including changes in and progress of our development activities, acquisitions of additional product candidates and changes in regulation.

        If we raise additional capital through marketing, sales and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish certain valuable rights to our product candidates, future revenue streams or research programs, technologies or grant licenses on terms that may not be favorable to us. If we raise additional capital through public or private equity offerings, the terms of these securities may include liquidation or other preferences that adversely affect our stockholders' rights. Further, to the extent that we raise additional capital through additional sales of common stock or securities convertible or exchangeable into common stock, your ownership interest will be diluted. See the section entitled "Dilution" for a more detailed description of the dilution to investors in the offering. If we raise additional capital through debt financing, we would be subject to fixed payment obligations and may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

        Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to obtain additional financing on favorable terms when needed, we may be required to delay, limit, reduce or terminate preclinical studies, clinical trials, or other research and development activities or one or more of our development programs.

Risks Related to the Discovery and Development of Our Product Candidates

Our business is dependent on our ability to advance our current and future product candidates through clinical trials, obtain marketing approval and ultimately commercialize them.

        We are early in our development efforts. We initiated our first clinical trial for NC318, our lead product candidate, in October 2018, and our second product candidate, NC410, is in preclinical development. Our ability to generate product revenues, which we do not expect will occur for several years, if ever, will depend heavily on the successful development and eventual commercialization of NC318, NC410 and any future product candidates we develop, which may never occur. Our current product candidates, including NC318 and NC410, and any future product candidates we develop will require additional preclinical or clinical development, management of clinical, preclinical and manufacturing activities, marketing approval in the United States and other jurisdictions, demonstration of effectiveness to pricing and reimbursement authorities, sufficient cGMP manufacturing supply for both preclinical and clinical development and commercial production, building of a commercial organization and substantial investment and significant marketing efforts before we generate any revenues from product sales.

        The clinical and commercial success of our current and future product candidates will depend on several factors, including the following:

16


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

        These factors, many of which are beyond our control, could cause us to experience significant delays or an inability to obtain regulatory approvals or commercialize our current or future product candidates, and could otherwise materially harm our business. Successful completion of preclinical studies and clinical trials does not mean that NC318, NC410 or any future product candidates we develop will receive regulatory approval. Even if regulatory approvals are obtained, we could experience significant delays or an inability to successfully commercialize our current and any future product candidates we develop, which would materially harm our business. If we are not able to generate sufficient revenue through the sale of any current or future product candidate, we may not be able to continue our business operations or achieve profitability.

The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time-consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be materially harmed.

        The time required to obtain approval by the FDA and comparable foreign authorities is unpredictable but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate's clinical development and may vary among jurisdictions. We have not obtained regulatory approval for any product candidate. Neither we nor any future collaborator is permitted to market any biological product in the United States until we or the future collaborator receives regulatory approval of a biologics license application, or BLA, from the FDA. It is possible that none of our current or future product candidates will ever obtain regulatory approval from the FDA or comparable foreign regulatory authorities.

        Our current and future product candidates could fail to receive regulatory approval for many reasons, including the following:

        This lengthy approval process as well as the unpredictability of clinical trial results may result in our failing to obtain regulatory approval to market any product candidate we develop, which would significantly harm our business, results of operations and prospects. The FDA and other comparable foreign authorities have substantial discretion in the approval process and in determining when or whether regulatory approval will be granted for any product candidate that we develop. Even if we believe the data collected from future clinical trials of our product candidates are promising, such data may not be sufficient to support approval by the FDA or any other regulatory authority.

        In addition, even if we were to obtain approval, the FDA may approve any of our product candidates for fewer or more limited indications, or a more limited patient population, than we request, may grant approval contingent on the performance of costly clinical trials or other postmarketing requirements, or may approve a product candidate with a label that does not include the labeling claims we believe are necessary or desirable for the successful commercialization of such product candidates.

        In addition, the FDA or comparable foreign regulatory authorities may change their policies, promulgate additional regulations, revise existing regulations or take other actions that may prevent or

18


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

delay approval of our future products under development on a timely basis. Such policy or regulatory changes could impose additional requirements upon us that could delay our ability to obtain approvals, increase the costs of compliance or restrict our ability to maintain any marketing authorizations we may have obtained. Any of the foregoing scenarios could materially harm the commercial prospects for our product candidates.

Clinical development involves a lengthy and expensive process with uncertain outcomes. We may incur additional costs and experience delays in developing and commercializing or be unable to develop and commercialize our current and future product candidates.

        To obtain the requisite regulatory approvals to commercialize any of our product candidates, we must demonstrate through extensive preclinical studies and clinical trials that our product candidates are safe, pure and potent in humans. Clinical testing is expensive and can take many years to complete, and its outcome is highly uncertain. Failure can occur at any time during the clinical trial process and our future clinical trial results may not be successful. We may experience delays in completing our clinical trials or preclinical studies and initiating or completing additional clinical trials. Although we initiated a Phase 1/2 clinical trial of NC318 in October 2018, we may experience delays in initiating or completing our planned clinical trials and development efforts. Additionally, we cannot be certain the ongoing and planned preclinical studies or clinical trials for NC318, NC410 or any future product candidates will begin on time, not require redesign, enroll an adequate number of subjects on time or be completed on schedule, if at all. We may also experience numerous unforeseen events during our clinical trials that could delay or prevent our ability to receive marketing approval or commercialize the product candidates we develop, including:

19


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

        We could encounter delays if a clinical trial is suspended or terminated by us, or by the IRBs of the institutions in which such trials are being conducted, ethics committees or the Data Safety Monitoring Board, or DSMB, for such trial or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of marketing approval of our product candidates. Further, the FDA or other regulatory authorities may disagree with our clinical trial design and our interpretation of data from clinical trials, or may change the requirements for approval even after they have reviewed and commented on the design for our clinical trials.

        Principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and may receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or a regulatory authority concludes that the financial relationship may have affected the interpretation of the trial, the integrity of the data generated at the applicable clinical trial site may be questioned and the utility of the clinical trial itself may be jeopardized, which could result in the delay or rejection of the marketing application we submit. Any such delay or rejection could prevent or delay us from commercializing our current or future product candidates.

        If we experience delays in the completion, or termination, of any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down the development and approval process for our product candidates and jeopardize our ability to commence product sales and generate revenues. Significant clinical trial delays could also allow our competitors to bring products to market before we do or shorten any periods during which we have the exclusive right to commercialize our product candidates.

Any such events would impair our ability to successfully commercialize our product candidates and may harm our business and results of operations.

        Any of these occurrences may significantly harm our business, financial condition and prospects. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates or result in the development of our product candidates stopping early.

Preclinical development is uncertain. Our preclinical programs may experience delays or may never advance to clinical trials, which would adversely affect our ability to obtain regulatory approvals or commercialize these programs on a timely basis or at all.

        With the exception of NC318, all of our product candidates are still in the preclinical discovery stage, and the risk of failure for such product candidates is high. In order to obtain FDA approval to market a new biologic we must demonstrate proof of safety, purity and potency, including efficacy, in humans. To meet these requirements we will have to conduct adequate and well-controlled clinical trials. Before we can commence clinical trials for a product candidate, we must complete extensive preclinical testing and studies that support our planned clinical trials in humans. We cannot be certain of the timely completion or outcome of our preclinical testing and studies and cannot predict if the FDA will accept our proposed clinical programs or if the outcome of our preclinical testing and studies will ultimately support the further development of our current or future product candidates. As a result, we cannot be sure that we will be able to submit INDs or similar applications for our preclinical programs on the timelines we expect, if at all, and we cannot be sure that submission of INDs or similar applications will result in the FDA or other regulatory authorities allowing clinical trials to begin.

        Conducting preclinical testing is a lengthy, time-consuming and expensive process. The length of time of such testing may vary substantially according to the type, complexity and novelty of the program, and often can be several years or more per program. Delays associated with programs for which we are conducting preclinical testing and studies may cause us to incur additional operating expenses. Moreover, we may be affected by delays associated with the preclinical testing and studies of certain programs that are the responsibility of Lilly or our potential future collaborators over which we have no control. The commencement and rate of completion of preclinical studies and clinical trials for a product candidate may be delayed by many factors, including but not limited to:

Positive results from preclinical studies and early-stage clinical trials may not be predictive of future results. Initial positive results in any of our clinical trials may not be indicative of results obtained when the trial is completed or in later stage trials.

        The results of preclinical studies may not be predictive of the results of clinical trials. Preclinical studies and early-stage clinical trials are primarily designed to test safety, to study pharmacokinetics and pharmacodynamics and to understand the side effects of product candidates at various doses and schedules, and the results of any early-stage clinical trials may not be predictive of the results of later-stage, large-scale efficacy clinical trials. In addition, initial success in clinical trials may not be indicative of results obtained when such trials are completed. There can be no assurance that any of our current or future clinical trials will ultimately be successful or support further clinical development of any of our product candidates. There is a high failure rate for drugs and biologics proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in

21


Table of Contents

clinical development even after achieving promising results in earlier studies, and any such setbacks in our clinical development could have a material adverse effect on our business and operating results.

        Even if our clinical trials are completed, the results may not be sufficient to obtain regulatory approval for our product candidates. Data obtained from preclinical and clinical activities are subject to varying interpretations, which may delay, limit or prevent regulatory approval. In addition, the results of our preclinical studies may not be predictive of the results of outcomes in human clinical trials. For example, our current or future product candidates may demonstrate different chemical, biological and pharmacological properties in patients than they do in laboratory studies or may interact with human biological systems in unforeseen or harmful ways. Product candidates in later stages of clinical trials may fail to show desired pharmacological properties or produce the necessary safety and efficacy results despite having progressed through preclinical studies and initial clinical trials. Even if we are able to initiate and complete clinical trials, the results may not be sufficient to obtain regulatory approval for our product candidates. In addition, we may experience regulatory delays or rejections as a result of many factors, including changes in regulatory policy during the period of our product candidate development. Any such delays could negatively impact our business, financial condition, results of operations and prospects.

Interim and preliminary results from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit, validation and verification procedures that could result in material changes in the final data.

        From time to time, we may publish interim data, including interim top-line results or preliminary results from our clinical trials. Interim data and results from our clinical trials are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Preliminary or top-line results also remain subject to audit, validation and verification procedures that may result in the final data being materially different from the interim and preliminary data we previously published. As a result, interim and preliminary data may not be predictive of final results and should be viewed with caution until the final data are available. Differences between preliminary or interim data and final data could significantly harm our business prospects and may cause the trading price of our common stock to fluctuate significantly.

Our approach to the discovery and development of product candidates using our FIND-IO platform is unproven and may not result in marketable products.

        The success of our business depends in part upon our ability to identify targets based on our proprietary FIND-IO platform and to develop and commercialize immunomedicines. Our approach to the discovery of targets using the FIND-IO platform is novel. We have not yet initiated or completed a clinical trial of any product candidate developed for a target identified from the FIND-IO platform. The platform may fail to accurately identify targets that modulate the immune system and are appropriate for immunomedicines. Even if we are able to identify targets from the FIND-IO platform and to develop corresponding product candidates, we cannot assure that such product candidates will achieve marketing approval to safely and effectively treat cancer or other disease states.

        If we uncover any previously unknown risks related to our FIND-IO platform, or if we experience unanticipated problems or delays in developing our FIND-IO product candidates, we may be unable to achieve our strategy of building an oncology pipeline of novel targets for new immunomedicines focused on non-responders, or meet our obligations under the Lilly Agreement.

Our current or future product candidates may cause undesirable side effects or have other properties when used alone or in combination with other approved products or investigational new drugs that could halt their clinical development, delay or prevent their regulatory approval, limit their commercial potential or result in significant negative consequences.

        Before obtaining regulatory approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that our product candidates are safe, pure and potent for use in each target indication, and failures can occur at any stage of testing. As with most biologics, use of our current or future product candidates could be associated with side effects or adverse events which can vary in severity from minor reactions to death and in frequency from infrequent to prevalent. There have been serious adverse side effects reported in response to immunotherapies in oncology.

        Immune-related adverse events that represent immune effects on normal tissue and can result from misdirected stimulation of the immune system are a common class of toxicity in immunomedicines. Possible adverse side effects that could occur with treatment with immunomedicines include an immunologic reaction early after administration which, while not necessarily adverse to the patient's health, could substantially limit the effectiveness of the treatment. In addition to any potential side effects caused by the product or product candidate, the administration process or related procedures also can cause adverse side effects. If unacceptable adverse events occur, our clinical trials or any future marketing authorization could be suspended or terminated.

        If unacceptable side effects arise in the development of our product candidates, we, the FDA, the IRBs at the institutions in which our studies are conducted or the DSMB could suspend or terminate our clinical trials or the FDA or comparable foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates for any or all targeted indications. Treatment-related side effects could also affect patient recruitment or the ability of enrolled patients to complete any of our clinical trials or result in potential product liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. We expect to have to train medical personnel using our product candidates to understand the side effect profiles for our clinical trials and upon any commercialization of any of our product candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in patient injury or death. Any of these occurrences may harm our business, financial condition and prospects significantly.

        Although our current and future product candidates have undergone and will undergo safety testing to the extent possible and, where applicable, under such conditions discussed with regulatory authorities, not all adverse effects of drugs can be predicted or anticipated. Immunomedicines and their method of action of harnessing the body's immune system are powerful and could lead to serious side effects that we only discover in clinical trials or during commercial marketing. Unforeseen side effects could arise either during clinical development or after our product candidates have been approved by regulatory authorities and the approved product has been marketed, resulting in the exposure of additional patients. So far, we have not demonstrated that NC318, NC410 or any other product candidate is safe in humans, and we cannot predict if ongoing or future clinical trials will do so. If any of our current or future product candidates fail to demonstrate safety and efficacy in clinical trials or do not gain marketing approval, we will not be able to generate revenue and our business will be harmed.

        In addition, we intend to pursue NC318 in part in combination with other therapies and may develop NC410 and future product candidates in combination with other therapies, which exposes us to additional risks relating to undesirable side effects or other properties. For example, the other therapies may lead to toxicities that are improperly attributed to our product candidates or the combination of our product candidates with other therapies may result in toxicities that the product candidate or other therapy does not produce when used alone. The other therapies we are using in combination may be removed from the market, or we may not be able to secure adequate quantities of such materials for which we have no

guaranteed supply contract, and thus be unavailable for testing or commercial use with any of our approved products. The other therapies we may use in combination with our product candidates may also be supplanted in the market by newer, safer or more efficacious products or combinations of products.

        Even if we successfully advance one of our product candidates through clinical trials, such trials will likely only include a limited number of subjects and limited duration of exposure to our product candidates. As a result, we cannot be assured that adverse effects of our product candidates will not be uncovered when a significantly larger number of patients are exposed to the product candidate. Further, any clinical trial may not be sufficient to determine the effect and safety consequences of taking our product candidates over a multi-year period.

        If any of our product candidates receives marketing approval, and we or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including:

        Any of the foregoing events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and result in the loss of significant revenues, which would materially harm our business. In addition, if one or more of our product candidates or our immunotherapeutic development approach generally prove to be unsafe, our entire technology platform and pipeline could be affected, which would also materially harm our business.

As an organization, we have limited experience designing and implementing clinical trials and we have never conducted pivotal clinical trials. Failure to adequately design a trial, or incorrect assumptions about the design of the trial, could adversely affect the ability to initiate the trial, enroll patients, complete the trial, or obtain regulatory approval on the basis of the trial results, as well as lead to increased or unexpected costs and in delayed timelines.

        The design and implementation of clinical trials is a complex process. We have limited experience designing and implementing clinical trials, and we may not successfully or cost-effectively design and implement clinical trials that achieve our desired clinical endpoints efficiently, or at all. A clinical trial that is not well designed may delay or even prevent initiation of the trial, can lead to increased difficulty in enrolling patients, may make it more difficult to obtain regulatory approval for the product candidate on the basis of the study results, or, even if a product candidate is approved, could make it more difficult to commercialize the product successfully or obtain reimbursement from third-party payors. Additionally, a trial that is not well-designed could be inefficient or more expensive than it otherwise would have been, or we may incorrectly estimate the costs to implement the clinical trial, which could lead to a shortfall in funding. We also expect to continue to rely on third parties to conduct our pivotal clinical trials. See "—Risks Related to Reliance on Third Parties—We rely or will rely on third parties to help conduct our ongoing and planned preclinical studies and clinical trials for NC318, NC410 and any future product

24

candidates we develop. If these third parties do not successfully carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain marketing approval for or commercialize NC318, NC410 and any future product candidates we develop, and our business could be materially harmed." Consequently, we may be unable to successfully and efficiently execute and complete clinical trials that are required for BLA submission and FDA approval of NC318, NC410 or future product candidates. We may require more time and incur greater costs than our competitors and may not succeed in obtaining regulatory approvals of product candidates that we develop.

If we or our collaborators encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise be adversely affected.

        The successful and timely completion of clinical trials in accordance with their protocols depends on, among other things, our ability to enroll a sufficient number of patients who remain in the trial until the trial's conclusion, including any follow-up period. We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons. The enrollment of patients depends on many factors, including:

        In addition, our clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas as our current and potential future product candidates. This competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial conducted by one of our competitors. Since the number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such sites. Moreover, because our current and potential future product candidates may represent a departure from more commonly used methods for cancer treatment, potential patients and their doctors may be inclined to use conventional therapies, such as chemotherapy, rather than enroll patients in our ongoing or any future clinical trial.

        Delays of difficulties in patient enrollment may result in increased costs or may affect the timing, outcome or completion of clinical trials, which would adversely affect our ability to advance the development of the product candidates we develop.

Because the number of subjects in our Phase 1/2 clinical trial of NC318 is small, the results from this trial, once completed, may be less reliable than results achieved in larger clinical trials.

        A study design that is considered appropriate includes a sufficiently large sample size with appropriate statistical power, as well as proper control of bias, to allow a meaningful interpretation of the results. The preliminary results of studies with smaller sample sizes, such as our ongoing Phase 1/2 clinical trial of NC318, can be disproportionately influenced by the impact the treatment had on a few individuals, which limits the ability to generalize the results across a broader community, thus making the study results less reliable than studies with a larger number of subjects. As a result, there may be less certainty that NC318 would achieve a statistically significant effect in any future clinical trials. If we conduct any future clinical trials of NC318, we may not achieve a statistically significant result or the same level of statistical significance seen, if any, in our Phase 1/2 clinical trial. Similarly, if we conduct a clinical trial of any other product candidate we develop, including NC410, with a smaller sample size, the results of any such trial may be less reliable than results achieved in larger clinical trials and may provide less certainty of achieving statistically significant effects in any future clinical trials.

We may be required to suspend, repeat or terminate our clinical trials if they are not conducted in accordance with regulatory requirements, the results are negative or inconclusive or the trials are not well designed.

        Clinical trials must be conducted in accordance with the FDA's current good clinical practices requirements, or cGCP, or analogous requirements of applicable foreign regulatory authorities. Clinical trials are subject to oversight by the FDA, other foreign governmental agencies and IRBs or ethical committees at the study sites where the clinical trials are conducted. In addition, clinical trials must be conducted with product candidates manufactured in accordance with applicable cGMP. Clinical trials may be suspended by the FDA, other foreign regulatory authorities, us, or by an IRB or ethics committee with respect to a particular clinical trial site, for various reasons, including:

We have chosen to prioritize development of NC318 and NC410. We may expend our limited resources on product candidates or indications that do not yield a successful product and fail to capitalize on other candidates or indications for which there may be a greater likelihood of success or may be more profitable.

        Because we have limited resources, we have strategically determined to prioritize development of NC318 and NC410 rather than other product candidates based, in part, on the significant resources required for developing and manufacturing immunomedicines. To date, no regulatory authority has granted approval for an immunomedicine targeting S15 or the LAIR pathway. As a result, we may be foregoing other potentially more profitable immunomedicines or therapies or those with a greater likelihood of success. Our decisions concerning the allocation of research, development, collaboration, management and financial resources toward particular product candidates or therapeutic areas may not lead to the development of any viable commercial product and may divert resources away from better opportunities. Similarly, our potential decisions to delay, terminate or collaborate with third parties with respect to, certain programs may subsequently also prove to be suboptimal and could cause us to miss valuable opportunities. If we make incorrect determinations regarding the viability or market potential of

26


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

any of our current or future product candidates or misread trends in the oncology or biopharmaceutical industry, our business, financial condition and results of operations could be materially adversely affected. As a result, we may fail to capitalize on viable commercial products or profitable market opportunities, be required to forego or delay pursuit of opportunities with other product candidates or other diseases and disease pathways that may later prove to have greater commercial potential than those we choose to pursue, or relinquish valuable rights to such product candidates through collaboration, licensing or other royalty arrangements in cases in which it would have been advantageous for us to invest additional resources to retain development and commercialization rights.

We may need to develop, or enter into a collaboration or partnership to develop, complementary or companion diagnostics for our current or future product candidates. If we, or our future collaborators, are unable to successfully develop such complementary or companion diagnostics, or experience significant delays in doing so, we may not realize the full commercial potential of our current or future product candidates.

        One of the key elements of our product development strategy is to identify cancer patient populations that may derive meaningful benefit from our current or future product candidates. Because predictive biomarkers may be used to identify the right patients for current or future product candidates, we believe that our success may depend, in part, on our ability to develop complementary or companion diagnostics in collaboration with partners.

        We have limited experience in the development of diagnostics and, as such, we expect to rely on future collaborators in developing appropriate diagnostics to pair with our current or future product candidates. We have not yet begun substantial discussions with any potential partners with respect to the development of complementary or companion diagnostics and may be unsuccessful in entering into collaborations for the development of any such diagnostics for our current or future product candidates.

        Complementary or companion diagnostics are subject to regulation by the FDA and similar comparable foreign regulatory authorities as medical devices and require separate regulatory approval or clearance prior to commercialization. If we, our collaborators, or any third parties that we engage to assist us, are unable to successfully develop complementary or companion diagnostics for our current or future product candidates or experience delays in doing so:

        If any of these events were to occur, our business could be materially harmed.

Risks Related to the Regulatory Approval and Commercialization of Product Candidates and Other Legal Compliance Matters

We may be unable to obtain FDA approval of our product candidates under applicable regulatory requirements. The denial or delay of any such approval would prevent or delay commercialization of our product candidates and adversely impact our potential to generate revenue, our business and our results of operations.

        To gain approval to market our product candidates in the United States, we must provide the FDA with clinical data that adequately demonstrate the safety, purity and potency, including efficacy, of the product candidate for the proposed indication or indications in a BLA submission. Product development is a long, expensive and uncertain process, and delay or failure can occur at any stage of any of our clinical development programs. A number of companies in the biotechnology and pharmaceutical industries have suffered significant setbacks in clinical trials, even after promising results in earlier preclinical studies or clinical trials. These setbacks have been caused by, among other things, preclinical findings made while

27


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

clinical trials were underway and safety or efficacy observations made in clinical trials, including previously unreported adverse events. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and the results of clinical trials by other parties may not be indicative of the results in trials we may conduct.

        We have not previously submitted a BLA or any other marketing application to the FDA or similar filings to comparable foreign regulatory authorities. A BLA or other similar regulatory filing requesting approval to market a product candidate must include extensive preclinical and clinical data and supporting information to establish that the product candidate is safe, pure and potent for each desired indication. The BLA or other similar regulatory filing must also include significant information regarding the chemistry, manufacturing and controls for the product.

        The research, testing, manufacturing, labeling, approval, marketing, sale and distribution of biological products are subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries, and such regulations differ from country to country. We are not permitted to market our product candidates in the United States or in any foreign countries until they receive the requisite approval from the applicable regulatory authorities of such jurisdictions.

        The FDA or comparable foreign regulatory authorities can delay, limit or deny approval of our product candidates for many reasons, including:

        Even if we eventually complete clinical testing and receive approval from the FDA or comparable foreign regulatory authorities for any of our product candidates, the FDA or comparable foreign regulatory authorities may grant approval contingent on the performance of costly additional clinical trials which may be required after approval. The FDA or comparable foreign regulatory authorities also may approve any of our product candidates for a more limited indication or a narrower patient population than we originally requested, and the FDA or comparable foreign regulatory authorities may not approve any of our product candidates with the labeling that we believe is necessary or desirable for the successful commercialization of any such product candidates.

        Of the large number of biopharmaceutical products in development, only a small percentage successfully complete the FDA or other regulatory bodies' approval processes and are commercialized. Any delay in obtaining, or inability to obtain, applicable regulatory approval would delay or prevent commercialization of our product candidates and would materially harm our business.

Even if a current or future product candidate receives marketing approval, it may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.

        If any current or future product candidate we develop receives marketing approval, whether as a single agent or in combination with other therapies, it may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors, and others in the medical community. For example, current approved immunotherapies, and other cancer treatments like chemotherapy and radiation therapy, are well established in the medical community, and doctors may continue to rely on these therapies. Our approach to targeting different components of the tumor microenvironment is novel and unproven. In addition, adverse events in clinical trials testing our product candidates or in clinical trials of others developing similar product candidates and the resulting publicity, as well as any other adverse events in the field of immuno-oncology that may occur in the future, could result in a decrease in demand for our current or future product candidates. If public perception is influenced by claims that the use of cancer immunotherapies is unsafe, whether related to our immunomedicines or our competitors' products, our products may not be accepted by the general public or the medical community. Future adverse events in immuno-oncology or the biopharmaceutical industry could also result in greater governmental regulation, stricter labeling requirements and potential regulatory delays in the testing or approvals of our products.

        If our current and any future product candidates we develop do not achieve an adequate level of acceptance, we may not generate significant product revenues and we may not become profitable. The degree of market acceptance of our current and any future product candidates, if approved for commercial sale, will depend on a number of factors, including:

The market opportunities for any current or future product candidate we develop, if approved, may be limited to those patients who are ineligible for established therapies or for whom prior therapies have failed, and may be small.

        Any revenue we are able to generate in the future from product sales will be dependent, in part, upon the size of the market in the United States and any other jurisdiction for which we gain regulatory approval and have commercial rights. If the markets or patient subsets that we are targeting are not as significant as we estimate, we may not generate significant revenues from sales of such products, even if approved.

        Cancer therapies are sometimes characterized as first-line, second-line or third-line, and the FDA often approves new therapies initially only for third-line use. When cancer is detected early enough, first-line therapy, usually chemotherapy, hormone therapy, surgery, radiation therapy or a combination of these, is sometimes adequate to cure the cancer or prolong life without a cure. Second- and third-line therapies are administered to patients when prior therapy is not effective. We may initially seek approval for NC318, NC410 and any other product candidates we develop as second- or third-line therapies. If we

29


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

do so, for those products that prove to be sufficiently beneficial, if any, we would expect potentially to seek approval as a first-line therapy, but there is no guarantee that any product candidate we develop, even if approved, would be approved for first-line therapy, and, prior to any such approvals, we may have to conduct additional clinical trials.

        The number of patients who have the types of cancer we are targeting may turn out to be lower than expected. Additionally, the potentially addressable patient population for our current or future product candidates may be limited, if and when approved. Even if we obtain significant market share for any product candidate, if and when approved, if the potential target populations are small, we may never achieve profitability without obtaining marketing approval for additional indications, including to be used as first- or second-line therapy.

We intend to develop NC318 in part in combination with other therapies and may develop NC410 and future product candidates in combination with other therapies, which exposes us to additional regulatory risks.

        We intend to develop NC318 in part in combination with other therapies and may develop NC410 and future product candidates in combination with one or more currently approved cancer therapies. These combinations have not been tested before and may, among other things, fail to demonstrate synergistic activity, may fail to achieve superior outcomes relative to the use of single agents or other combination therapies, or may fail to demonstrate sufficient safety or efficacy traits in clinical trials to enable us to complete those clinical trials or obtain marketing approval for the combination therapy.

        In addition, we did not develop or obtain regulatory approval for, and we do not manufacture or sell, any of these approved therapeutics. Therefore, even if any product candidate we develop were to receive marketing approval or be commercialized for use in combination with other existing therapies, we would continue to be subject to the risk that the FDA or comparable foreign regulatory authorities could revoke approval of the therapy used in combination with our product candidate or that safety, efficacy, manufacturing or supply issues could arise with these existing therapies. This could result in our own products being removed from the market or being less successful commercially. Combination therapies are commonly used for the treatment of cancer, and we would be subject to similar risks if we develop any of our product candidates for use in combination with other drugs or for indications other than cancer.

        We may also evaluate NC318, NC410, or any future product candidate in combination with one or more other cancer therapies that have not yet been approved for marketing by the FDA or comparable foreign regulatory authorities. We will not be able to market and sell NC318, NC410 or any product candidate we develop in combination with any such unapproved cancer therapies that do not ultimately obtain marketing approval.

        If the FDA or comparable foreign regulatory authorities do not approve these other biological products or revoke their approval of, or if safety, efficacy, manufacturing or supply issues arise with, the biologics we choose to evaluate in combination with NC318, NC410 or any product candidate we develop, we may be unable to obtain approval of or market any such product candidate.

Even if we receive marketing approval of a product candidate, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. If we fail to comply or experience unanticipated problems with our products, we may be subject to administrative and judicial enforcement, including monetary penalties, for non-compliance and our approved products, if any, could be deemed misbranded or adulterated and prohibited from continued distribution.

        Any marketing approvals that we receive for any current or future product candidate may be subject to limitations on the approved indicated uses for which the product may be marketed or the conditions of approval, or contain requirements for potentially costly post-market testing and surveillance to monitor the safety and efficacy of the product candidate. The FDA may also require implementation of a REMS as a condition of approval of any product candidate, which could include requirements for a medication guide,

30


Table of Contents

physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or a comparable foreign regulatory authority approves a product candidate, the manufacturing processes, labeling, packaging, distribution, adverse event and deviation reporting, storage, advertising, promotion, import and export and record keeping for the product candidate will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMP and cGCP, for any clinical trials that we may conduct post-approval. Later discovery of previously unknown problems with any approved candidate, including adverse events of unanticipated severity or frequency, or with our or our third-party manufacturers' manufacturing processes or facilities, or failure to comply with regulatory requirements, may result in, among other things:

        Given the nature of biologics manufacturing, there is a risk of contamination. Any contamination could materially adversely affect our ability to produce product candidates on schedule and could, therefore, harm our results of operations and cause reputational damage. Some of the raw materials and other components required in our manufacturing process are derived from biologic sources. Such raw materials are difficult to procure and may be subject to contamination or recall. A material shortage, contamination, recall or restriction on the use of biologically derived substances in the manufacture of our product or product candidates could adversely impact or disrupt the commercial manufacturing or the production of clinical material, which could materially and adversely affect our development and commercialization timelines and our business, financial condition, results of operations and prospects and could adversely affect our ability to meet our supply obligations.

        Moreover, the FDA strictly regulates the promotional claims that may be made about drug and biological products. In particular, an approved product may not be promoted for uses that are not approved by the FDA as reflected in the product's approved labeling, or off-label uses. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. The FDA has issued guidance on the factors that it will consider in determining whether a firm's product communication is consistent with the FDA-required labeling for that product, and those factors contain complexity and potential for overlap and misinterpretation. A company that is found to have improperly promoted off-label uses of their products may be subject to significant civil, criminal and administrative penalties.

        The FDA and other regulatory authorities' policies may change and additional government regulations may be enacted that could prevent, limit or delay marketing approval of a product. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.

31

        Any government investigation of alleged violations of law could require us to expend significant time and resources in response, and could generate negative publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and generate revenue from our products. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our company and our operating results will be adversely affected.

        Certain policies of the Trump Administration may impact our business and industry. President Trump has taken several executive actions, including the issuance of a number of Executive Orders, that could impose significant burdens on, or otherwise materially delay, the FDA's ability to engage in routine oversight activities such as implementing statutes through rulemaking, issuance of guidance, and review and approval of marketing applications. It is difficult to predict how these orders will be implemented, and the extent to which they will impact the FDA's ability to exercise its regulatory authority. If these executive actions impose restrictions on the FDA's ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted.

        In addition, if we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.

Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not mean that we will be successful in obtaining and maintaining marketing approval of our current and future product candidates in other jurisdictions.

        Obtaining and maintaining marketing approval of our current and future product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain marketing approval in any other jurisdiction, while a failure or delay in obtaining marketing approval in one jurisdiction may have a negative effect on the marketing approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

        We may also submit marketing applications in other countries. Regulatory authorities in jurisdictions outside of the United States have requirements for approval of product candidates with which we must comply prior to marketing in those jurisdictions. Obtaining foreign marketing approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory requirements in international markets or fail to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed.

We depend on our information technology systems, and any failure of these systems could harm our business. Security breaches, loss of data, and other disruptions could compromise sensitive information related to our business or prevent us from accessing critical information and expose us to liability, which could adversely affect our business, results of operations and financial condition.

        We collect and maintain information in digital form that is necessary to conduct our business, and we are dependent on our information technology systems and those of third parties to operate our business. In the ordinary course of our business, we collect, store and transmit large amounts of confidential

32


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

information, including intellectual property, proprietary business information and personal information, and data to comply with cGMP and data integrity requirements. It is critical that we do so in a secure manner to maintain data security and data integrity of such information. We have established physical, electronic and organizational measures to safeguard and secure our systems to prevent a data compromise. We have also outsourced elements of our information technology infrastructure, and as a result a number of third-party vendors may or could have access to our confidential information. Our internal information technology systems and infrastructure, and those of our current and any future collaborators, contractors and consultants and other third parties on which we rely, are vulnerable to damage from computer viruses, malware, natural disasters, terrorism, war, telecommunication and electrical failures, cyber-attacks or cyber-intrusions, phishing, persons inside our organization or persons with access to systems inside our organization.

        The risk of a security breach or disruption or data loss, including by computer hackers, foreign governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. In addition, the prevalent use of mobile devices that access confidential information increases the risk of data security breaches, which could lead to the loss of confidential information or other intellectual property. The costs to us to mitigate network security problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant, and while we have implemented security measures to protect our data security and information technology systems, our efforts to address these problems may not be successful, and these problems could result in unexpected interruptions, delays, cessation of service and other harm to our business and our competitive position. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our product development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on third parties to conduct clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business. Moreover, if a computer security breach affects our systems or results in the unauthorized release of personally identifiable information, our reputation could be materially damaged. In addition, such a breach may require notification to governmental agencies, the media or individuals pursuant to various federal and state privacy and security laws, if applicable, including the Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended, and its implementing rules and regulations, as well as regulations promulgated by the Federal Trade Commission and state breach notification laws. We would also be exposed to a risk of loss or litigation and potential liability, which could materially adversely affect our business, results of operations and financial condition.

The successful commercialization of our product candidates will depend in part on the extent to which third-party payors, including governmental authorities and private health insurers, provide coverage and adequate reimbursement levels, as well as implement pricing policies favorable for our product candidates. Failure to obtain or maintain coverage and adequate reimbursement for our product candidates, if approved, could limit our ability to market those products and decrease our ability to generate revenue.

        The availability of coverage and adequacy of reimbursement by third-party payors, including managed care plans, governmental healthcare programs, such as Medicare and Medicaid and private health insurers is essential for most patients to be able to afford medical services and pharmaceutical products such as our product candidates that receive FDA approval. Our ability to achieve acceptable levels of coverage and reimbursement for our products or procedures using our products by third-party payors will have an effect on our ability to successfully commercialize our product candidates. Obtaining coverage and adequate reimbursement for our products may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. Separate reimbursement for the product itself or the treatment or procedure in which our product is used may not be available. A decision by a third-party payor not to cover or not to separately reimburse for our products or procedures using our

33

products could reduce physician utilization of our products once approved. Assuming there is coverage for our product candidates, or procedures using our product candidates by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. We cannot be sure that coverage and reimbursement in the United States, the European Union or elsewhere will be available for our current or future product candidates, or for any procedures using such product candidates, and any reimbursement that may become available may not be adequate or may be decreased or eliminated in the future.

        Our ability to successfully commercialize any product candidate, whether as a single agent or combination therapy, will also depend in part on the extent to which coverage and reimbursement for these product candidates and related treatments will be available from third-party payors. Third-party payors decide which medications they will pay for and establish reimbursement levels. It is difficult to predict at this time what government authorities and third-party payors will decide with respect to coverage and reimbursement for our current and future product candidates.

        In addition, third-party payors are increasingly challenging prices charged for pharmaceutical and biological products and services, and many third-party payors may refuse to provide coverage and reimbursement for particular drugs or biologics when an equivalent generic drug, biosimilar or a less expensive therapy is available. It is possible that a third-party payor may consider our product candidates as substitutable and only offer to reimburse patients for the less expensive product. Even if we show improved efficacy or improved convenience of administration with our product candidates, pricing of existing third-party therapeutics may limit the amount we will be able to charge for our product candidates. These third-party payors may deny or revoke the reimbursement status of our product candidates, if approved, or establish prices for our product candidates at levels that are too low to enable us to realize an appropriate return on our investment. If reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize our product candidates, and may not be able to obtain a satisfactory financial return on our product candidates.

        There is significant uncertainty related to the insurance coverage and reimbursement of newly-approved products, especially novel products like our immunomedicines. To date, no regulatory authority has granted approval for an immunomedicine targeting S15 or the LAIR pathway. The Medicare and Medicaid programs are increasingly used as models in the United States for how private third-party payors and other governmental payors develop their coverage and reimbursement policies for drugs and biologics. Some third-party payors may require pre-approval of coverage for new or innovative devices or drug therapies before they will reimburse healthcare providers who use such therapies. We cannot predict at this time what third-party payors will decide with respect to the coverage and reimbursement for our product candidates.

        No uniform policy for coverage and reimbursement for products exist among third-party payors in the United States. Therefore, coverage and reimbursement for products can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that may require us to provide scientific and clinical support for the use of our product candidates to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. Furthermore, rules and regulations regarding reimbursement change frequently, in some cases on short notice, and we believe that changes in these rules and regulations are likely.

        Additionally, if we or our collaborators develop companion diagnostic tests for use with our product candidates, we, or our collaborators, will be required to obtain coverage and reimbursement for these tests separate and apart from the coverage and reimbursement we seek for our product candidates, once approved. While we and our collaborators have not yet developed any companion diagnostic test for our product candidates, if we or our collaborators do, there is significant uncertainty regarding the ability to obtain coverage and adequate reimbursement for the same reasons applicable to our product candidates.

        Moreover, increasing efforts by third-party payors in the United States and abroad to cap or reduce healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our product candidates. We expect to experience pricing pressures in connection with the sale of our product candidates due to the trend toward managed health care, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs and biologics and surgical procedures and other treatments, has become intense. As a result, increasingly high barriers are being erected to the entry of new products.

Enacted healthcare legislation, changes in healthcare law and implementation of regulations, as well as changes in healthcare policy, may increase the difficulty and cost for us to commercialize our product candidates, may impact our business in ways that we cannot currently predict, could affect the prices we may set, and could have a material adverse effect on our business and financial condition.

        In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. In particular, there have been and continue to be a number of initiatives at the U.S. federal and state levels that seek to reduce healthcare costs and improve the quality of healthcare. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively, the ACA, was passed, which substantially changes the way healthcare is financed by both governmental and private insurers, and significantly impacts the U.S. pharmaceutical industry. The ACA, among other things, subjects biological products to potential competition by lower-cost biosimilars, addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs and creates a new Medicare Part D coverage gap discount program in which, as a condition of coverage of its products under Medicare Part D, manufacturers must now agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period.

        Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges, as well as efforts by President Trump's administration to repeal or replace certain aspects of the ACA, and to alter the implementation of the ACA and related laws. For example, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or the Tax Act, includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the "individual mandate." On January 22, 2018, the President signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain ACA-mandated fees, including the so-called "Cadillac" tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based on market share and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act of 2018, among other things, amended the ACA, effective January 1, 2019, to reduce the coverage gap in most Medicare drug plans, commonly referred to as the "donut hole." Also, in 2018, the Centers for Medicare and Medicaid Services, or CMS, issued final rules permitting further collections and payments to and from certain ACA qualified health plans and health insurance issuers under the ACA risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. In December 2018, a United States District Court Judge for the Northern District of Texas ruled that the entire ACA is unconstitutional because the tax penalty associated with the

35


Table of Contents

"individual mandate" was repealed by Congress as part of the Tax Act. This ruling is under appeal and stayed pending appeal. While the United States District Court Judge for the Northern District of Texas, as well as the Trump Administration and CMS, have stated that the ruling will have no effect while this appeal is pending, it is unclear how this decision, subsequent appeals and other efforts to invalidate the ACA, regulations promulgated under the ACA and related laws, or portions thereof will impact the ACA, its implementation and our business.

        Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. On August 2, 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation's automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2027 unless additional congressional action is taken. On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers.

        Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives. For example, effective January 1, 2014, CMS began bundling into the hospital outpatient prospective payment rate the Medicare payments for most laboratory tests ordered while a patient received services in a hospital outpatient setting. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for any product candidate we develop or complementary or companion diagnostics or additional pricing pressures.

        CMS may develop new payment and delivery models, such as bundled payment models. In addition, recently there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several U.S. Congressional inquiries and proposed and enacted federal and state legislation that legislators intend to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under government payor programs, and review the relationship between pricing and manufacturer patient programs. The Trump Administration's budget proposals for fiscal 2019 and 2020 contain drug price control measures, including measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid and to eliminate cost sharing for generic drugs for low-income patients. For example, the Trump Administration released a "Blueprint" to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out of pocket costs of drug products paid by consumers. The U.S. Department of Health and Human Services has started soliciting feedback on some of these measures and, at the same, is implementing others under its existing authority. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020. This final rule codified CMS's policy change that was effective January 1, 2019. Although a number of these measures may require additional authorization to become effective, Congress and the Trump Administration have each indicated that they will continue to seek new legislative and/or administrative measures to control drug costs. We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the extent to which the U.S. federal government covers particular healthcare products and services and could limit the amounts that the U.S. federal government will pay for healthcare products and services. This could result in reduced demand for our product candidates or additional pricing pressures.

        Individual states in the United States have also increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient

36

reimbursement limitations, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or other restrictions on coverage or access could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our product candidates that we successfully commercialize or put pressure on our product pricing.

        Additionally, on May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn and Matthew Bellina Right to Try Act of 2017, or the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

        We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action in the United States. If we or any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.

Our relationships with customers, third-party payors and others may be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

        Healthcare providers, physicians and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our current and future arrangements with healthcare providers, third-party payors, customers, and others may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations, which may constrain the business or financial arrangements and relationships through which we research, as well as, sell, market and distribute any products for which we obtain marketing approval. The applicable federal and state healthcare laws and regulations that may affect our ability to operate include, but are not limited to:

        Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available under such laws, it is possible that some of our business activities could be subject to challenge under one or more of such laws. The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Ensuring that our business arrangements with third parties comply with applicable healthcare laws, as well as responding to investigations by government authorities, can be time and resource consuming and can divert management's attention from the business.

        If our operations are found to be in violation of any of the laws described above or any other government regulations that apply to us, we may be subject to penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, possible exclusion from participation in federal and state funded healthcare programs, contractual damages and the curtailment or restricting of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws. Further, if the physicians or other providers or entities with whom we expect to do business are found not to be in compliance with applicable laws, they may be subject to criminal, civil and administrative sanctions, including exclusion from government funded healthcare programs. In addition, the approval and commercialization of any product candidate we develop outside the United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws. All of these could harm our ability to operate our business and our financial results.

We are subject to certain U.S. and foreign anti-corruption, anti-money laundering, export control, sanctions and other trade laws and regulations. We can face serious consequences for violations.

        Among other matters, U.S. and foreign anti-corruption, anti-money laundering, export control, sanctions and other trade laws and regulations, which are collectively referred to as Trade Laws, prohibit companies and their employees, agents, clinical research organizations, legal counsel, accountants, consultants, contractors and other partners from authorizing, promising, offering, providing, soliciting, or receiving directly or indirectly, corrupt or improper payments or anything else of value to or from recipients in the public or private sector. Violations of Trade Laws can result in substantial criminal fines and civil penalties, imprisonment, the loss of trade privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm and other consequences.

        Our business is heavily regulated and therefore involves significant interaction with public officials. We have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals, universities and other organizations. We also expect our non-U.S. activities to increase in time. Additionally, in many other countries, the health care providers who prescribe pharmaceuticals are employed by their government, and the purchasers of pharmaceuticals are government entities; therefore, our dealings with these prescribers and purchasers are subject to regulation

under the U.S. Foreign Corrupt Practices Act of 1977, as amended, or FCPA. We plan to engage third parties for clinical trials and/or to obtain necessary permits, licenses, patent registrations, and other regulatory approvals and we can be held liable for the corrupt or other illegal activities of our personnel, agents, or partners, even if we do not explicitly authorize or have prior knowledge of such activities. In particular, our operations will be subject to FCPA, which prohibits, among other things, U.S. companies and their employees and agents from authorizing, promising, offering, or providing, directly or indirectly, corrupt or improper payments or anything else of value to foreign government officials, employees of public international organizations and foreign government-owned or affiliated entities, candidates for foreign political office, and foreign political parties or officials thereof. Recently, the SEC and Department of Justice have increased their FCPA enforcement activities with respect to biotechnology and pharmaceutical companies. There is no certainty that all of our employees, agents, suppliers, manufacturers, contractors, or collaborators, or those of our affiliates, will comply with all applicable laws and regulations, particularly given the high level of complexity of these laws. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers, or our employees, the closing down of facilities, including those of our suppliers and manufacturers, requirements to obtain export licenses, cessation of business activities in sanctioned countries, implementation of compliance programs and prohibitions on the conduct of our business. Any such violations could also result in prohibitions on our ability to offer our products in one or more countries as well as difficulties in manufacturing or continuing to develop our products, and could materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, and our business, prospects, operating results and financial condition.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

        We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemicals and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.

        Although we maintain workers' compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological or hazardous materials.

Risks Related to Manufacturing

Given our limited operating history, our manufacturing experience as an organization and with our manufacturing facility is limited.

        Manufacturing is a critical component of our approach to developing immunomedicines and we have invested significantly in our manufacturing facility. We currently manufacture our product candidates for preclinical and clinical trials.

        The manufacture of drugs for clinical trials and for commercial sale is subject to oversight by the FDA to ensure compliance with cGMP and by other regulatory authorities under other laws, regulations and standards. We cannot assure you that we can successfully manufacture our products in compliance with cGMP and with any other applicable laws, regulations and standards in sufficient quantities for clinical trials or for commercial sale, or in a timely or economical manner.

40

        Our manufacturing facility requires specialized personnel and is expensive to operate and maintain. Validation is an ongoing process that must be maintained to allow us to manufacture under cGMP guidelines. We cannot guarantee that our facility will remain in compliance with cGMP.

        The manufacture of pharmaceutical products is a highly complex process in which a variety of difficulties may arise from time to time. We are currently the sole manufacturer of NC318 and NC410 and if anything were to interfere with our continuing manufacturing operations in our facility, it could materially adversely affect our business and financial condition.

        If we fail to develop manufacturing capacity and experience, whether internally or with a third party, or fail to manufacture our product candidates economically or on reasonable scale or volumes, or in accordance with cGMP, our development programs and commercialization of any approved products will be materially adversely affected. This may result in delays in commencing or continuing our clinical trials for NC318 or filing our IND for NC410. Any such delays could materially adversely affect our business and financial condition.

The loss of our third-party manufacturing partners or our, or our partners', failure to comply with applicable regulatory requirements or to supply sufficient quantities at acceptable quality levels or prices, or at all, would materially and adversely affect our business.

        Although we currently manufacture our product candidates for preclinical and clinical trials, certain elements of manufacturing, including Master Cell Bank manufacturing and fill-finish services, take place at qualified third-party contract manufacturing organizations, or CMOs. If approved, commercial supply of NC318, NC410 and any future product candidates may be manufactured at a CMO or CMOs.

        The facilities used by our CMOs to manufacture our product candidates are subject to various regulatory requirements and may be subject to the inspection of the FDA or other regulatory authorities. We do not control the manufacturing process at our CMOs, and are completely dependent on them for compliance with current regulatory requirements. If we or our CMOs cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or comparable regulatory authorities in foreign jurisdictions, we may not be able to rely on their manufacturing facilities for the manufacture of elements of our product candidates. In addition, we have limited control over the ability of our CMOs to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority finds our facilities or those of our CMOs inadequate for the manufacture of our product candidates or if such facilities are subject to enforcement action in the future or are otherwise inadequate, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates.

        Additionally, our CMOs may experience manufacturing difficulties due to resource constraints or as a result of labor disputes or unstable political environments. If our CMOs were to encounter any of these difficulties, our ability to provide our product candidate to patients in clinical trials, or to provide product for the treatment of patients once approved, would be jeopardized.

Changes in methods of product candidate manufacturing or formulation may result in additional costs or delay.

        As product candidates proceed through preclinical studies to late-stage clinical trials towards potential approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize processes and results. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the materials manufactured using altered processes. Such changes may also require additional testing, FDA notification or FDA approval. This could delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more

41

clinical trials, increase clinical trial costs, delay approval of our product candidates and jeopardize our ability to commence sales and generate revenue.

We are subject to multiple manufacturing risks, any of which could substantially increase our costs and limit supply of our product candidates.

        The process of manufacturing immunomedicines, including our product candidates, is complex, time-consuming, highly regulated and subject to several risks, including:

        We may also make changes to our manufacturing processes at various points during development, for a number of reasons, such as controlling costs, achieving scale, decreasing processing time, increasing manufacturing success rate or other reasons. Such changes carry the risk that they will not achieve their intended objectives, and any of these changes could cause our product candidates to perform differently and affect the results of our ongoing or future clinical trials. In some circumstances, changes in the manufacturing process may require us to perform ex vivo comparability studies and to collect additional data from patients prior to undertaking more advanced clinical trials. For instance, changes in our process during the course of clinical development may require us to show the comparability of the product used in earlier clinical phases or at earlier portions of a trial to the product used in later clinical phases or later portions of the trial.

We depend on third-party suppliers for key materials used in our manufacturing processes, and the loss of these third-party suppliers or their inability to supply us with adequate materials could harm our business.

        We rely on third-party suppliers for certain materials and components required for the production of our product candidates. Our dependence on these third-party suppliers and the challenges we may face in obtaining adequate supplies of materials involve several risks, including limited control over pricing, availability, and quality and delivery schedules. As a small company, our negotiation leverage is limited and we are likely to get lower priority than our competitors that are larger than we are. We cannot be certain that our suppliers will continue to provide us with the quantities of these raw materials that we require or satisfy our anticipated specifications and quality requirements. Any supply interruption in limited or sole sourced raw materials could materially harm our ability to manufacture our product candidates until a new source of supply, if any, could be identified and qualified. We may be unable to find a sufficient alternative supply channel in a reasonable time or on commercially reasonable terms. Any performance failure on the part of our suppliers could delay the development and potential commercialization of our product candidates, including limiting supplies necessary for clinical trials and regulatory approvals, which would have a material adverse effect on our business.

We may be unable to successfully scale-up manufacturing of our product candidates in sufficient quality and quantity, which would delay or prevent us from developing and, if approved, commercializing our product candidates.

        In order to conduct clinical trials of our product candidates, we will need to manufacture them in large quantities. If one or more of our product candidates progress to late-stage development, we may incur significant expenses in the expansion and/or construction of manufacturing facilities and increases in personnel in order to manufacture product candidates. Currently, our product candidates are manufactured in small quantities for use in various preclinical studies and our ongoing Phase 1/2 clinical trial of NC318. We cannot assure you that we will be able to successfully manufacture additional product candidates at a larger scale in a timely or economical manner, or at all. If we are unable to successfully increase our manufacturing scale or capacity, the development, testing, and clinical trials of our current or future product candidates may be delayed or infeasible, and regulatory approval or commercial launch of any resulting product may be delayed or not obtained, which could significantly harm our business.

Risks Related to Intellectual Property

We have filed patent applications for our lead product candidates, but no patent has yet issued from these applications. If we are unable to obtain and maintain patent protection for our product candidates, or if the scope of the patent protection obtained is not sufficiently broad or robust, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize our product candidates may be adversely affected.

        Our success depends, in large part, on our ability to obtain and maintain patent protection in the United States and other countries with respect to our product candidates. We and our licensors have sought, and intend to seek, to protect our proprietary position by filing patent applications in the United States and abroad related to our product candidates and technology that are important to our business. No patent has yet issued from our patent applications.

        The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has, in recent years, been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued that protect our technology or product candidates or that effectively prevent others from commercializing competitive technologies and product candidates. Because patent applications in the United States and most other countries are confidential for a period of time after filing, and some remain so until issued, we cannot be certain that we or our licensors were the first to file a patent application relating to any particular aspect of a product candidate. Furthermore, if third parties have filed such patent applications, we may challenge their ownership, for example in a derivation proceeding before the U.S. Patent and Trademark Office, or USPTO, to determine who has the right to the claimed subject matter in the applications. Similarly, if our patent applications are challenged in a derivation proceeding, the USPTO may hold that a third-party is entitled to certain patent ownership rights instead of us. We may then be forced to seek a license from the third party that may not be available on commercially favorable terms, or at all.

        The patent prosecution process is expensive, time-consuming and complex, and we may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.

        Even if the patent applications we license or own do issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us or otherwise provide us with any competitive advantage. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products that do not infringe our patents.

We are party to a license agreement with Yale University under which we acquired rights to intellectual property related to certain of our product candidates. If we breach our obligations under this agreement, the agreement could be terminated, which would adversely affect our business and prospects.

        We are a party to a license agreement with Yale pursuant to which we in-license patents and technology for certain of our product candidates. This license imposes various diligence, milestone payment, royalty, insurance and other obligations on us. If we fail to comply with these and other obligations or otherwise materially breach this license agreement, Yale may have the right to terminate the license. If this agreement is terminated, we may not be able to develop, manufacture, market or sell the product candidates or products covered by the agreement, or we would have to negotiate a new or reinstated agreement, which may not be available to us on equally favorable terms, or at all.

Our intellectual property agreements with third parties may be subject to disagreements over contract interpretation, which could narrow the scope of our rights to the relevant intellectual property or technology or increase our financial or other obligations to our licensors.

        Certain provisions in our intellectual property agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could affect the scope of our rights to the relevant intellectual property or technology, or affect financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

        Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents and/or applications will be due to be paid to the USPTO and various government patent agencies outside of the United States over the lifetime of our licensed patents and/or applications and any patent rights we own or may own in the future. We rely, in part, on our outside counsel or our licensing partners to pay these fees due to the USPTO and to non-U.S. patent agencies. The USPTO and various non-U.S. government patent agencies require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application process. In many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. There are situations, however, in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, potential competitors might be able to enter the market and this circumstance could have a material adverse effect on our business.

We may not be able to protect our intellectual property rights throughout the world.

        Filing, prosecuting and enforcing patents on product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States are and could remain less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may be less likely to be able to prevent third parties from infringing our patents in all countries outside the United States, or from selling or importing products that infringe our patents in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection, but enforcement

is not as strong as that in the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

        Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations and prospects may be adversely affected.

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

        Changes in either the patent laws or interpretation of the patent laws in the United States could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. Assuming that other requirements for patentability are met, prior to March 2013, in the United States, the first to invent the claimed invention was entitled to the patent, while outside the United States, the first to file a patent application was entitled to the patent. After March 2013, under the Leahy-Smith America Invents Act, or the America Invents Act, enacted in September 2011, the United States transitioned to a first inventor to file system in which, assuming that other requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third party was the first to invent the claimed invention. The America Invents Act also includes a number of significant changes that affect the way patent applications are prosecuted and also may affect patent litigation. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity or ownership of a patent by USPTO administered post-grant proceedings, including post-grant review, inter partes review and derivation proceedings. The America Invents Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        In addition, the patent positions of companies in the development and commercialization of biologics and pharmaceuticals are particularly uncertain. Recent rulings from the U.S. Court of Appeals for the Federal Circuit and the U.S. Supreme Court have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the validity and enforceability of patents. Depending on future actions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future.

We may become involved in lawsuits to protect or enforce our intellectual property, which could be expensive, time-consuming and unsuccessful.

        Competitors may infringe our patents or the patents of our licensors, or we may be required to defend against claims of infringement. Countering infringement or unauthorized use claims or defending against claims of infringement can be expensive and time-consuming. Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could

45


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

substantially increase our operating losses and reduce the resources available for development activities or any future marketing, sales or distribution activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.

        In addition, many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we own, develop or license.

Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court. We may not be able to protect our trade secrets in court.

        If we or one of our licensing partners initiate legal proceedings against a third party to enforce any patent that is issued covering one of our product candidates, the defendant could counterclaim that the patent covering our product candidate is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, written description or non-enablement. In addition, patent validity challenges may, under certain circumstances, be based upon non-statutory obviousness-type double patenting, which, if successful, could result in a finding that the claims are invalid for obviousness-type double patenting or the loss of patent term, including a patent term adjustment granted by the USPTO, if a terminal disclaimer is filed to obviate a finding of obviousness-type double patenting. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld information material to patentability from the USPTO, or made a misleading statement, during prosecution. Third parties also may raise similar claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re-examination, post grant review, inter partes review and equivalent proceedings in foreign jurisdictions. Such proceedings could result in the revocation or cancellation of or amendment to our patents in such a way that they no longer cover our product candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. We cannot be certain that there is no invalidating prior art of which the patent examiner and we or our licensing partners were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we could lose part, and perhaps all, of the patent protection on one or more of our product candidates. Such a loss of patent protection could have a material adverse impact on our business.

        In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable or that we elect not to patent, processes for which patents are difficult to enforce and any other elements of our product candidate discovery and development processes that involve proprietary know-how, information or technology that is not covered by patents, including portions of our FIND-IO platform. However, trade

46


Table of Contents

secrets can be difficult to protect, and some courts inside and outside the United States are less willing or unwilling to protect trade secrets.

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business and financial condition.

        Our commercial success depends upon our ability and the ability of any collaborators to develop, manufacture, market and sell our product candidates and use our proprietary technologies without infringing the proprietary rights and intellectual property of third parties. We cannot provide any assurances that third-party patents do not exist which might be enforced against our current manufacturing methods, product candidates or future methods or products, resulting in either an injunction prohibiting our manufacture or sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties.

        The biotechnology and pharmaceutical industries are characterized by extensive and complex litigation regarding patents and other intellectual property rights. We may in the future become party to, or be threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to our product candidates and technology, including post grant review and inter partes review before the USPTO. The risks of being involved in such litigation and proceedings may also increase as our product candidates approach commercialization and as we gain greater visibility as a public company. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit. There is a risk that third parties may choose to engage in litigation with us to enforce or to otherwise assert their patent rights against us. Even if we believe such claims are without merit, a court of competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed, which could materially and adversely affect our ability to commercialize any of our product candidates or technologies covered by the asserted third-party patents.

        If we are found to infringe a third party's valid and enforceable intellectual property rights, we could be required to obtain a license from such third party to continue developing, manufacturing and marketing our product candidates and technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. We could be forced, including by court order, to cease developing, manufacturing and commercializing the infringing technology or product candidates. In addition, we could be found liable for monetary damages, including treble damages and attorneys' fees, if we are found to have willfully infringed a patent or other intellectual property right. A finding of infringement could prevent us from manufacturing and commercializing our product candidates or force us to cease some of our business operations, which could materially harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business, financial condition, results of operations and prospects.

Others may claim an ownership interest in our intellectual property and our product candidates, which could expose us to litigation and have a significant adverse effect on our prospects.

        While we are presently unaware of any claims or assertions by third parties with respect to our patents or other intellectual property, we cannot guarantee that a third party will not assert a claim or an interest in any of such patents or intellectual property. For example, a third party may claim an ownership interest in one or more of our, or our licensors', patents or other proprietary or intellectual property rights. A third party could bring legal actions against us to seek monetary damages or enjoin clinical testing, manufacturing or marketing of the affected product candidate or product. If we become involved in any litigation, it could consume a substantial portion of our resources and cause a significant diversion of effort by our technical and management personnel. If any such action is successful, in addition to any potential

47


Table of Contents

liability for damages, we could be required to obtain a license to continue to manufacture or market the affected product candidate or product, in which case we could be required to pay substantial royalties or grant cross-licenses to patents. We cannot, however, assure you that any such license would be available on acceptable terms, if at all. Ultimately, we could be prevented from commercializing a product, or forced to cease some aspect of our business operations as a result of claims of patent infringement or violation of other intellectual property rights. Further, the outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance, including the demeanor and credibility of witnesses and the identity of any adverse party. This is especially true in intellectual property cases, which may turn on the testimony of experts as to technical facts upon which experts may reasonably disagree. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations or prospects.

If we are unable to protect the confidentiality of our proprietary information, the value of our technology and products could be adversely affected.

        Trade secrets and know-how can be difficult to protect. To maintain the confidentiality of trade secrets and proprietary information, we enter into confidentiality agreements with our employees, consultants, collaborators and others upon the commencement of their relationships with us. These agreements require that all confidential information developed by the individual or made known to the individual by us during the course of the individual's relationship with us be kept confidential and not disclosed to third parties. Our agreements with employees and our personnel policies also provide that any inventions conceived by the individual in the course of rendering services to us shall be our exclusive property. However, we cannot guarantee that we have entered into such agreements with each party that may have or have had access to our trade secrets or proprietary technology and processes, and individuals with whom we have these agreements may not comply with their terms. Thus, despite such agreement, there can be no assurance that such inventions will not be assigned to third parties. In the event of unauthorized use or disclosure of our trade secrets or proprietary information, these agreements, even if obtained, may not provide meaningful protection, particularly for our trade secrets or other confidential information. To the extent that our employees, consultants or contractors use technology or know-how owned by third parties in their work for us, disputes may arise between us and those third parties as to the rights in related inventions. To the extent that an individual who is not obligated to assign rights in intellectual property to us is rightfully an inventor of intellectual property, we may need to obtain an assignment or a license to that intellectual property from that individual, or a third party or from that individual's assignee. Such assignment or license may not be available on commercially reasonable terms or at all. We also seek to preserve the integrity and confidentiality of our trade secrets by other means, including maintaining physical security of our premises and physical and electronic security of our information technology systems. However, these security measures may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property.

        Adequate remedies may not exist in the event of unauthorized use or disclosure of our proprietary information. The disclosure of our trade secrets would impair our competitive position and may materially harm our business, financial condition and results of operations. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to maintain trade secret protection could adversely affect our competitive business position. In addition, others may independently discover or develop our trade secrets and proprietary information, and the existence of our own trade secrets affords no protection against such independent discovery. For example, a public presentation in the scientific or popular press on the properties of our product candidates could motivate a third party, despite any perceived difficulty, to assemble a team of scientists having backgrounds similar to those of our employees to attempt to independently reverse engineer or otherwise duplicate our antibody technologies to replicate our success.

We may be subject to claims asserting that our employees, consultants or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers.

        Many of our employees, consultants or advisors are currently, or were previously, employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees, consultants and advisors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these individuals, or we, have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual's current or former employer, or that patents and applications we have filed to protect inventions of these employees, even those related to one or more of our product candidates, are rightfully owned by their former or current employer. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

        Any registered trademarks or trade names may be challenged, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential partners or customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trademarks, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could adversely impact our financial condition or results of operations.

Intellectual property rights do not necessarily address all potential threats.

        The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

        Should any of these events occur, they could significantly harm our business, financial condition, results of operations and prospects.

Risks Related to Reliance on Third Parties

We rely or will rely on third parties to help conduct our ongoing and planned preclinical studies and clinical trials for NC318, NC410 and any future product candidates we develop. If these third parties do not successfully carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain marketing approval for or commercialize NC318, NC410 and any future product candidates we develop, and our business could be materially harmed.

        We currently do not have the ability to independently conduct preclinical studies that comply with the regulatory requirements known as current good laboratory practice, or GLP, requirements. We also do not currently have the ability to independently conduct any clinical trials. The FDA and regulatory authorities in other jurisdictions require us to comply with regulations and standards, including cGCP, or requirements for conducting, monitoring, recording and reporting the results of clinical trials, in order to ensure that the data and results are scientifically credible and accurate and that the trial subjects are adequately informed of the potential risks of participating in clinical trials. We rely on medical institutions, clinical investigators, contract laboratories and other third parties, such as CROs, to conduct GLP-compliant preclinical studies and cGCP-compliant clinical trials on our product candidates properly and on time. While we have agreements governing their activities, we control only certain aspects of their activities and have limited influence over their actual performance. The third parties with whom we contract for execution of our GLP-compliant preclinical studies and our cGCP-compliant clinical trials play a significant role in the conduct of these studies and trials and the subsequent collection and analysis of data. These third parties are not our employees and, except for restrictions imposed by our contracts with such third parties, we have limited ability to control the amount or timing of resources that they devote to our current or future product candidates. Although we rely on these third parties to conduct our GLP-compliant preclinical studies and cGCP-compliant clinical trials, we remain responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with its investigational plan and protocol and applicable laws and regulations, and our reliance on the CROs does not relieve us of our regulatory responsibilities.

        Many of the third parties with whom we contract may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other drug development activities that could harm our competitive position. Further, under certain circumstances, these third parties may terminate their agreements with us upon as little as 10 days' prior written notice. Some of these agreements may also be terminated by such third parties under certain other circumstances. If the third parties conducting our preclinical studies or our clinical trials do not adequately perform their contractual duties or obligations, experience significant business challenges, disruptions or failures, do not meet expected deadlines, terminate their agreements with us or need to be replaced, or if the quality or accuracy of the data they obtain is compromised due to their failure to adhere to our protocols or to GLP

and cGCP, or for any other reason, we may need to enter into new arrangements with alternative third parties. This could be difficult, costly or impossible, and our preclinical studies or clinical trials may need to be extended, delayed, terminated or repeated. As a result, we may not be able to obtain regulatory approval in a timely fashion, or at all, for the applicable product candidate, our financial results and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed.

We may depend on Lilly, Yale or other third-party collaborators for the discovery, development and commercialization of certain of our current and future product candidates. If our collaborations are not successful, we may not be able to capitalize on the market potential of these product candidates.

        In November 2018, we entered into the Lilly Agreement, which is focused on using our FIND-IO platform to identify novel oncology targets for additional research and drug discovery by ourselves and Lilly. Pursuant to the Lilly Agreement, we granted Lilly the exclusive right to obtain worldwide exclusive licenses to research, develop, manufacture and commercialize compounds and products directed to oncology targets identified through our research collaboration. Lilly will have the exclusive ability to control the development and commercialization of any targets it chooses to license on a global basis. Our lack of control over the clinical development of certain programs under the Lilly Agreement could result in delays or other difficulties in the development and commercialization of product candidates. Our right to receive certain milestone and royalty payments may be subsequently delayed, if we receive any at all. In the event Lilly terminates the Lilly Agreement, we would be prevented from receiving any milestone payments, royalty payments and other benefits under that agreement, which would have a materially adverse effect on our results of operations. Furthermore, in the event Lilly does not purchase and exercise any of its options, we will not be eligible to receive any future milestone payments under the Lilly Agreement, which could require us to seek additional funding in order to avoid delaying, reducing the scope of, or suspending, one or more of our research and development programs or clinical trials.

        We have also entered into the SRA with Yale in which we agreed to provide funding for a research program aimed at discovering new targets for immunomedicines. We have and would expect to have limited control over the amount and timing of resources that are employed in the research program. The research program may not be successful, and as a result, we may not be able to identify, develop and commercialize products from this collaboration.

        In the future, we may form or seek other strategic alliances, joint ventures or collaborations, or enter into additional licensing arrangements with third parties that we believe will complement or augment our development and commercialization efforts with respect to product candidates we develop.

        Our collaborations pose, and potential future collaborations involving our product candidates may pose, the following risks to us:

51


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

        If we enter into additional collaboration agreements and strategic partnerships or license our intellectual property, products or businesses, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations, which could delay our timelines or otherwise adversely affect our business. We also cannot be certain that, following a strategic transaction or license, we will achieve the revenue or net income that justifies such transaction. Any of the factors set forth above and any delays in entering into new collaborations or strategic partnership agreements related to any product candidate we develop could delay the development and commercialization of our product candidates, which would harm our business prospects, financial condition and results of operations.

We may seek to establish additional collaborations, and, if we are not able to establish them on commercially reasonable terms, we may have to alter our development and commercialization plans.

        The advancement of our product candidates and development programs and the potential commercialization of our current and future product candidates will require substantial additional cash to fund expenses. For some of our current or future product candidates, we may decide to collaborate with additional pharmaceutical and biotechnology companies with respect to development and potential commercialization. Any of these relationships may require us to incur non-recurring and other charges, increase our near and long term expenditures, issue securities that dilute our existing stockholders, or disrupt our management and business.

        We face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Whether we reach a definitive agreement for other collaborations will depend, among other things, upon our assessment of the collaborator's resources and expertise, the terms and conditions of the proposed collaboration and the collaborator's evaluation of a number of factors. Those factors may include the design or results of clinical trials, the progress of our clinical trials, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate.

        Further, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for future product candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view them as having the requisite potential to demonstrate safety and efficacy.

52

        We may also be restricted under existing collaboration agreements from entering into future agreements on certain terms with potential collaborators. Such exclusivity could limit our ability to enter into strategic collaborations with future collaborators. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

        We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of the product candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any marketing or sales activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenue.

Risks Related to Our Business

We are highly dependent on our key personnel, and if we are not successful in attracting, motivating and retaining highly qualified personnel, we may not be able to successfully implement our business strategy.

        We are highly dependent on members of our executive team. The loss of the services of any of them may adversely impact the achievement of our objectives. Any of our executive officers could leave our employment at any time, as all of our employees are "at-will" employees. We currently only have "key person" insurance on Michael Richman, our President and Chief Executive Officer, and on Dr. Lieping Chen, our scientific founder, in his role as consultant to us. The loss of the services of Mr. Richman, Dr. Chen or one or more of our other executive officers could impede the achievement of our research, development and commercialization objectives.

        We continue to work with Dr. Chen on discovering novel immunomedicines through his consulting agreement and our SRA with Yale. If we are no longer able to leverage our relationships with Dr. Chen and Yale, our ability to discover additional targets for immunomedicines may be impeded, which may adversely impact the achievement of our objectives.

        Recruiting and retaining qualified employees, consultants and advisors for our business, including scientific and technical personnel, will also be critical to our success. Competition for skilled personnel is intense and the turnover rate can be high. We may not be able to attract and retain personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies and academic institutions for skilled individuals. In addition, failure to succeed in preclinical studies, clinical trials or applications for marketing approval may make it more challenging to recruit and retain qualified personnel. The inability to recruit, or the loss of services of certain executives, key employees, consultants or advisors, may impede the progress of our research, development and commercialization objectives and have a material adverse effect on our business, financial condition, results of operations and growth prospects.

We face significant competition from other biotechnology and pharmaceutical companies, and our operating results will suffer if we fail to compete effectively.

        The biotechnology industry is intensely competitive and subject to rapid and significant technological change. Our current or future product candidates may face competition from major pharmaceutical companies, specialty pharmaceutical companies, universities and other research institutions and from products and therapies that currently exist or are being developed, some of which products and therapies we may not currently know about. Many of our competitors have significantly greater financial, manufacturing, marketing, product development, technical and human resources than we do. Large

pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining marketing approvals, recruiting patients and manufacturing pharmaceutical products, and they may also have products that have been approved or are in late stages of development, and collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make the product candidates that we develop obsolete. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. As a result of all of these factors, our competitors may succeed in obtaining patent protection and/or FDA or other regulatory approval or discovering, developing and commercializing products in our field before we do, which could result in our competitors establishing a strong market position before we are able to enter the market.

        Our competitors may obtain FDA or other regulatory approval of their product candidates more rapidly than we may or may obtain patent protection or other intellectual property rights that limit our ability to develop or commercialize our product candidates or platform technologies. Our competitors may also develop drugs or discovery platforms that are more effective, more convenient, more widely used or less costly than our product candidates or our FIND-IO platform or, in the case of drugs, have a better safety profile than our product candidates. These competitors may also be more successful than us in manufacturing and marketing their products, and have significantly greater financial resources and expertise in research and development.

        There are a large number of companies developing or marketing treatments for cancer, including many major pharmaceutical and biotechnology companies. Currently marketed oncology drugs and therapeutics range from traditional cancer therapies, including chemotherapy, to antibody-drug conjugates, such as Genentech's Kadcyla, to immune checkpoint inhibitors targeting CTLA-4, such as BMS' Yervoy, and PD-1/PD-L1, such as BMS' Opdivo, Merck & Co.'s Keytruda and Genentech's Tecentriq, to T cell-engager immunotherapies, such as Amgen's Blincyto. In addition, numerous compounds are in clinical development for cancer treatment. In addition, numerous compounds are in clinical development for cancer treatment. Many of these companies are well-capitalized and have significant clinical experience. See "Business—Competition."

        Smaller and other early stage companies may also prove to be significant competitors. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our current and future product candidates. In addition, the biopharmaceutical industry is characterized by rapid technological change. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Technological advances or products developed by our competitors may render our product candidates obsolete, less competitive or not economical.

        Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient, have a broader label, are marketed more effectively, are reimbursed or are less expensive than any products that we may develop. Our competitors may also obtain patent protection or other intellectual property rights that limit our ability to develop or commercialize our product candidates or platform technologies. Even if our product candidates achieve marketing approval, they may be priced at a significant premium over competitive products if any have been approved by then, resulting in reduced competitiveness. If we do not compete successfully, we may not generate or derive sufficient revenue from any product candidate for which we obtain marketing approval and may not become or remain profitable.

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

        As our development plans and strategies develop, and as we transition into operating as a public company, we expect to need additional managerial, operational, marketing, sales, financial and other personnel. Future growth would impose significant added responsibilities on members of management, including:

        Our future financial performance and our ability to advance development of and, if approved, commercialize NC318, NC410 and any future product candidates we develop will depend, in part, on our ability to effectively manage any future growth, and our management may have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities.

        We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors and consultants to provide certain services. We cannot assure you that the services of independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain marketing approval of any current or future product candidates or otherwise advance our business. We cannot assure you that we will be able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, or at all.

        If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize NC318, NC410 and any future product candidates we develop and, accordingly, may not achieve our research, development and commercialization goals.

If we are unable to establish marketing, sales and distribution capabilities for NC318, NC410 or any other product candidate that may receive regulatory approval, we may not be successful in commercializing those product candidates if and when they are approved.

        We do not have sales or marketing infrastructure. To achieve commercial success for NC318, NC410 and any other product candidate for which we may obtain marketing approval, we will need to establish a sales and marketing organization. In the future, we expect to build a focused sales and marketing infrastructure to market some of our product candidates in the United States, if and when they are approved. There are risks involved with establishing our own marketing, sales and distribution capabilities. For example, recruiting and training a sales force is expensive and time consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

        Factors that may inhibit our efforts to market our products on our own include:

55

Pursuant to 17 C.F.R. Section 200.83

        If we are unable to establish our own marketing, sales and distribution capabilities and are forced to enter into arrangements with, and rely on, third parties to perform these services, our revenue and our profitability, if any, are likely to be lower than if we had developed such capabilities ourselves. In addition, we may not be successful in entering into arrangements with third parties to sell, market and distribute our product candidates or may be unable to do so on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we do not establish marketing, sales and distribution capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidates.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of our product candidates.

        We face an inherent risk of product liability exposure related to the testing of our product candidates in human trials and may face greater risk if we commercialize any products that we develop. Product liability claims may be brought against us by subjects enrolled in our trials, patients, healthcare providers or others using, administering or selling our products. If we cannot successfully defend ourselves against such claims, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

        While we currently hold trial liability insurance coverage consistent with industry standards, the amount of coverage may not adequately cover all liabilities that we may incur. We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise. We intend to expand our insurance coverage for products to include the sale of commercial products if we obtain marketing approval for our product candidates, but we may be unable to obtain commercially reasonable product liability insurance. A successful product liability claim or series of claims brought against us, particularly if judgments exceed our insurance coverage, could decrease our cash and adversely affect our business and financial condition.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

        We are subject to the periodic reporting requirements of the Exchange Act. We designed our disclosure controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

        These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

Our ability to use our net operating loss carryforwards to offset future taxable income may be subject to certain limitations.

        We have incurred substantial losses during our history and do not expect to become profitable in the near future, and we may never achieve profitability. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire. As of June 30, 2019, we had federal and state net operating loss carryforwards of $43.5 million and $43.0 million, respectively. The federal and state net operating loss carryforwards will begin to expire, if not utilized, by 2036. Limitations imposed by the applicable jurisdictions on our ability to utilize net operating loss carryforwards could cause income taxes to be paid earlier than would be paid if such limitations were not in effect and could cause such net operating loss carryforwards to expire unused, in each case reducing or eliminating the benefit of such net operating loss carryforwards. Furthermore, we may not be able to generate sufficient taxable income to utilize our net operating loss carryforwards before they expire. If any of these events occur, we may not derive some or all of the expected benefits from our net operating loss carryforwards. In addition, we may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, including this offering, some of which may be outside of our control. As a result, even if we earn net taxable income, our ability to use our net operating loss and tax credit carryforwards may be materially limited, which could harm our future operating results by effectively increasing our future tax obligations.

Risks Related to Our Common Stock and this Offering

An active trading market for our common stock may not be sustained and you may not be able to sell your shares at or above the public offering price, or at all.

        Prior to our IPO, there was no public market for shares of our common stock. Although our common stock is listed on the Nasdaq Global Select Market, or Nasdaq, an active, liquid trading market for our shares may not be sustained. In the absence of an active trading market for our common stock, you may not be able to sell your common stock at or above the public offering price or at the time that you would like to sell.

The price of our common stock may be volatile and fluctuate substantially, which could result in substantial losses for purchasers of our common stock in this offering.

        Our stock price is likely to be volatile. The stock market in general and the market for biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, you may not

57

be able to sell your common stock at or above the public offering price, or at all. The market price for our common stock may be influenced by many factors, including:

58


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

        In addition, the stock market in general, and Nasdaq and biotechnology companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance. The realization of any of the above risks or any of a broad range of other risks, including those described in this "Risk Factors" section, could have a dramatic and material adverse impact on the market price of our common stock.

If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our stock, the price of our stock could decline.

        The trading market for our common stock relies, in part, on the research and reports that industry or financial analysts publish about us or our business. As a newly public company, we have only limited coverage by equity research analysts. If additional analysts do not commence coverage of us, the trading price of our stock could decrease. In addition, if one or more of the analysts covering our business issue adverse reports about us or downgrade their evaluations of our stock, the price of our stock could decline. If one or more of these analysts cease to cover our stock or fail to publish reports on us regularly, we could lose visibility in the market for our stock, which, in turn, could cause our stock price to decline.

If you purchase our common stock in this offering, you will incur immediate and substantial dilution in the book value of your shares.

        The public offering price of our common stock is substantially higher than the as adjusted net tangible book value per share of our common stock. Therefore, if you purchase our common stock in this offering, you will pay a price per share that substantially exceeds the as adjusted net tangible book value per share after the closing of this offering. To the extent outstanding options to purchase shares of our common stock are exercised, you will incur further dilution. Based on the public offering price of $            per share, which is the last reported sale price of our common stock on the Nasdaq Global Select Market on                , 2019, and our net tangible book value as of June 30, 2019, you will experience immediate dilution of $            per share, representing the difference between our net tangible book value per share as of June 30, 2019. See the section entitled "Dilution" for a more detailed description of the dilution to investors in the offering.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall, even if our business is doing well.

        If our existing stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the market price of our common stock could decline. As of June 30, 2019, we had outstanding a total of 22,714,765 shares of common stock.

        The resales of            shares of our common stock are subject to lock-up agreements pertaining to this offering that will expire 90 days from the date of this prospectus, subject to earlier release of all or a portion of the shares subject to such agreements by the underwriters in this offering. After the lock-up agreements expire, substantially all of the shares of common stock outstanding prior to this offering will be eligible for sale in the public market, subject to the applicable volume, manner of sale and other limitations imposed under the federal securities laws.

        We have registered 5,167,502 shares of common stock on Registration Statements on Forms S-8 that were either subject to outstanding options or reserved for future issuance under our existing equity incentive plans as of May 13, 2019, and as a result these shares will become eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules and the lock-up agreements described above. If these additional shares of common stock are sold, or if it is perceived that they will be sold, in the public market, the market price of our common stock could decline.

        In addition, the holders of            shares, or approximately        %, of our common stock outstanding as of June 30, 2019 are entitled to rights with respect to the registration of their shares under the Securities Act, subject to the lock-up agreements described above. See "Description of Capital Stock—Registration Rights." Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares purchased by affiliates. Any sales of securities by these stockholders could have a material adverse effect on the market price of our common stock.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

        Provisions in our amended and restated certificate of incorporation and amended and restated bylaws may delay or prevent an acquisition of us or a change in our management. For example, our board of directors has the authority to issue up to 10,000,000 shares of preferred stock. The board of directors can fix the price, rights, preferences, privileges and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock may delay or prevent a change of control transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders may be adversely affected. An issuance of shares of preferred stock may result in the loss of voting control to other stockholders.

        These provisions also include a classified board of directors, a prohibition on actions by written consent of our stockholders and the ability of our board of directors to issue preferred stock without stockholder approval. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which limits the ability of stockholders owning in excess of 15% of our outstanding voting stock to merge or combine with us. Although we believe these provisions collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirers to negotiate with our board of directors, they would apply even if an offer rejected by our board were considered beneficial by some stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management.

Our executive officers, directors and current beneficial owners of 5% or more of our common stock and their respective affiliates exercise significant influence over our company, which limits your ability to influence corporate matters and could delay or prevent a change in corporate control.

        Our executive officers, directors and current beneficial owners of 5% or more of our common stock and their respective affiliates beneficially own, in the aggregate, a majority of our outstanding common stock. As a result, these stockholders, if they act together, will be able to influence our management and affairs and the outcome of matters submitted to our stockholders for approval, including the election of directors and any sale, merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership might adversely affect the market price of our common stock by:

        See the section entitled "Principal Stockholders" for more information regarding the ownership of our outstanding common stock by our executive officers, directors and their affiliates.

We are an emerging growth company, and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our common stock less attractive to investors.

        We are an emerging growth company, as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in this prospectus and our periodic reports and proxy statements and exemptions from the requirements of holding nonbinding advisory votes on executive compensation and stockholder approval of any golden parachute payments not previously approved. We will remain an emerging growth company until the earliest of (i) December 31, 2024, (ii) the last day of the first fiscal year in which we have total annual gross revenues of at least $1.07 billion, (iii) the last day of the first fiscal year in which the market value of our common stock that is held by non-affiliates exceeds $700.0 million on June 30th and (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

        Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to take advantage of this extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements could be impaired, investors may lose confidence in our financial reporting and the trading price of our common stock may decline.

        Pursuant to Section 404 of the Sarbanes-Oxley Act, our management will be required to report upon the effectiveness of our internal control over financial reporting beginning with the annual report for our fiscal year ending December 31, 2020. When we lose our status as an "emerging growth company," our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation. To comply with the requirements of being a reporting company under the Exchange Act, we will need to implement additional financial and management controls, reporting systems and procedures and hire additional accounting and finance staff.

        We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Our independent registered public accounting firm will not be required to provide an attestation report on the effectiveness of our internal control over financial reporting so long as we qualify as an "emerging growth company," which may increase the risk that material weaknesses or significant deficiencies in our internal control over financial reporting go

61

undetected. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition, results of operations or cash flows. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness or significant deficiency in our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

We have broad discretion in how we use the net proceeds from this offering and may not use these proceeds effectively, which could affect our results of operations and cause our stock price to decline.

        Our management will have broad discretion in the application of the net proceeds from this offering, including for any of the purposes described in the section entitled "Use of Proceeds," and you will be relying on the judgment of our management regarding the application of these proceeds. You will not have the opportunity, as part of your investment decision, to assess whether we are using the proceeds appropriately. Our management might not use the net proceeds from this offering in ways that ultimately increase the value of your investment. If we do not use these proceeds in ways that enhance stockholder value, we may fail to achieve expected financial results or cause delays to our clinical development timelines, which could cause our stock price to decline.

We do not intend to pay dividends on our common stock, so any returns will be limited to the value of our stock.

        We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will therefore be limited to the appreciation of their stock.

We have incurred and will continue to incur significantly increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives.

        As a public company, and particularly after we are no longer an emerging growth company, we have incurred and expect to continue to incur significant legal, accounting, investor relations and other expenses that we did not incur as a private company, which we anticipate could be between $2.5 million and $4.5 million annually. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of Nasdaq and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel devote a substantial amount of time to these compliance initiatives. Moreover, we expect these rules and regulations to substantially increase our legal and financial compliance costs and to make some activities more time consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to incur substantial costs to maintain sufficient coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers. Moreover, these rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

We may be subject to securities litigation, which is expensive and could divert management attention.

        The market price of our common stock may be volatile, and in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management's attention from other business concerns, which could seriously harm our business.

Our amended and restated bylaws designate the Court of Chancery of the State of Delaware or the United States District Court for the District of Delaware as the exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

        Our amended and restated bylaws provide that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware or, if subject matter jurisdiction over the matter that is the subject of such action is vested exclusively in the federal courts, the United States District Court for the District of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers and employees, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, (iv) any action or proceeding to interpret, apply, enforce or determine the validity of our certificate of incorporation or the bylaws or (v) any action asserting a claim that is governed by the internal affairs doctrine, in each case subject to the Court of Chancery or the United States District Court for the District of Delaware, as applicable, having personal jurisdiction over the indispensable parties named as defendants therein. In addition, any person holding, owning or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and to have consented to this provision of our bylaws. The choice of forum provision does not apply to any actions arising under the Securities Act or the Exchange Act. The choice of forum provision may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or employees, which may discourage such lawsuits against us and our directors, officers and employees even though an action, if successful, might benefit our stockholders. Stockholders who do bring a claim in the Court of Chancery or the United States District Court for the District of Delaware could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near the jurisdiction. The Court of Chancery or the United States District Court for the District of Delaware may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Alternatively, if a court were to find this provision of our amended and restated bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs, which could have a material adverse effect on our business, financial condition or results of operations.

USE OF PROCEEDS

        We estimate that the net proceeds from the sale of shares of our common stock in this offering will be approximately $             million, or approximately $             million if the underwriters exercise their option to purchase additional shares in full, assuming a public offering price of $            per share, which is the last reported sale price of our common stock on the Nasdaq Global Select Market on                , 2019, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

        Each $1.00 increase or decrease in the assumed public offering price of $            per share, which is the last reported sale price of our common stock on the Nasdaq Global Select Market on                , 2019, would increase or decrease, respectively, the net proceeds from this offering by approximately $             million, assuming the number of shares offered by us, as set forth on the cover of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. We may also increase or decrease the number of shares we are offering. An increase or decrease of 1.0 million in the number of shares we are offering would increase or decrease, respectively, the net proceeds from this offering, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, by approximately $             million, assuming the public offering price remains the same. We do not expect that a change in the public offering price or the number of shares offered by us by these amounts would have a material effect on our intended use of the net proceeds from this offering, although it may impact the amount of time prior to which we may need to seek additional capital.

        As of June 30, 2019, we had $192.7 million in cash and cash equivalents, excluding restricted cash. We intend to use the net proceeds from this offering, together with our existing cash and cash equivalents, as follows:

        Our expected use of the net proceeds from this offering represents our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. As of the date of this prospectus, we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the closing of this offering or the amounts that we will actually spend on the uses set forth above. The amounts and timing of our actual expenditures and the extent of our research and development activities may vary significantly depending on numerous factors, including the progress of our development efforts, the timing and costs associated with the manufacture and supply of any of our product candidates and any unforeseen cash needs. As a result, our management will have broad discretion over the use of the net proceeds from this offering.

        Pending the uses described above, we intend to invest the net proceeds from this offering in interest-bearing, investment-grade securities, certificates of deposit or government securities.

        We believe that our existing cash and cash equivalents, together with the net proceeds from this offering, will be sufficient to fund our planned operations into                . We have based this estimate on assumptions that may prove to be incorrect, and we could use our available capital resources sooner than we currently expect. After this offering, we will require substantial additional capital in order to continue to advance NC318, NC410 and future product candidates through preclinical studies, clinical trials, regulatory approval and commercialization.

DILUTION

        If you invest in our common stock in this offering, your ownership interest will be immediately diluted to the extent of the difference between the public offering price per share of our common stock and the as adjusted net tangible book value per share of our common stock immediately after this offering.

        As of June 30, 2019, we had a historical net tangible book value of $178.5 million, or $7.86 per share of our common stock. Our net tangible book value per share represents total tangible assets less total liabilities divided by the number of shares of common stock outstanding on June 30, 2019, including 167,518 shares of restricted common stock that were unvested or subject to repurchase.

        After giving effect to the sale of            shares of common stock in this offering, assuming a public offering price of $            per share, which is the last reported sale price of our common stock on the Nasdaq Global Select Market on                    , 2019, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of June 30, 2019 would have been $             million, or $            per share. This represents an immediate increase in net tangible book value of $            per share to existing stockholders and an immediate dilution of $            per share to new investors participating in this offering. The following table illustrates this per share dilution to new investors:

Each $1.00 increase or decrease in the assumed public offering price of $            per share, which is the last reported sale price of our common stock on the Nasdaq Global Select Market on                        , 2019, would increase or decrease, respectively, our as adjusted net tangible book value as of June 30, 2019 after this offering by $             million, or $            per share, and would increase or decrease, respectively, dilution to investors in this offering by $            per share, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. We may also increase or decrease the number of shares we are offering. An increase of 1.0 million in the number of shares we are offering in this offering would increase our as adjusted net tangible book value as of June 30, 2019 after this offering by $             million, or $            per share, and would decrease dilution to investors in this offering by $            per share, and a decrease of 1.0 million in the number of shares we are offering in this offering would decrease our as adjusted net tangible book value as of June 30, 2019 after this offering by $             million, or $            per share, in each case each assuming the assumed public offering price remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

        If the underwriters exercise their option to purchase            additional shares of our common stock in full, the as adjusted net tangible book value after this offering would be $            per share, the increase in net tangible book value per share would be $            and the dilution per share to new investors would be $            per share, assuming a public offering price of $            per share, which is the last reported sale price of our common stock on the Nasdaq Global Select Market on                    , 2019, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        You should read the following discussion and analysis of our financial condition and results of operations together with the section entitled "Selected Financial Data" and our financial statements and the related notes appearing elsewhere in this prospectus. This discussion and other parts of this prospectus contain forward-looking statements, such as statements of our plans, objectives, expectations and intentions, that involve risks and uncertainties. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section entitled "Risk Factors."

Overview

        We are a clinical-stage biopharmaceutical company committed to discovering and developing novel, first-in-class immunomedicines to treat cancer and other immune-related diseases by restoring normal immune function. We view the immune system holistically and, rather than target one specific immune cell type, we focus on understanding biological pathways, the interactions of cells and the role each interaction plays in an immune response. Through our proprietary Functional, Integrated, NextCure Discovery in Immuno-Oncology, or FIND-IO, platform, we study various immune cells to discover and understand targets and structural components of immune cells and their functional impact in order to develop immunomedicines. We are focused on patients who do not respond to current therapies, patients whose cancer progresses despite treatment and patients with cancer types not adequately addressed by available therapies. We are committed to discovering and developing first-in-class immunomedicines, which are immunomedicines that use new or unique mechanisms of action to treat a medical condition, for these patients.

        Our lead product candidate, NC318, is a first-in-class immunomedicine against a novel immunomodulatory receptor called Siglec-15, or S15. In October 2018, we initiated a Phase 1/2 clinical trial of NC318 in patients with advanced or metastatic solid tumors. We completed enrollment of the Phase 1 portion of this trial in August 2019 and preliminary data will be presented at the Society for Immunotherapy of Cancer, or SITC, annual meeting in November 2019. We began enrolling patiuents in the Phase 2 portion of the trial in October 2019 and expect to announce initial data from the Phase 2 portion by the end of 2020. Our second product candidate, NC410, is a novel immunomedicine designed to block immune suppression mediated by an immune modulator called Leukocyte-Associated Immunoglobulin-like Receptor 1, or LAIR-1. We expect to submit an investigational new drug application, or IND, to the U.S. Food and Drug Administration, or FDA, for NC410 in the first quarter of 2020.

        On May 13, 2019, we closed our IPO, in which we sold 5,750,000 shares of our common stock, at a public offering price of $15.00 per share, for aggregate gross proceeds of $86.3 million.

Financial Overview

        Since commencing operations in 2015, we have devoted substantially all of our efforts and financial resources to organizing and staffing our company, identifying business development opportunities, raising capital, securing intellectual property rights related to our product candidates, building and optimizing our manufacturing capabilities and conducting discovery, research and development activities for our product candidates, discovery programs and FIND-IO platform.

        We have not generated any revenue from product sales and only limited revenue from other sources and, as a result, we have never been profitable and have incurred net losses since the commencement of our operations. Our net losses for the years ended December 31, 2018 and 2017 were $22.8 million and $15.5 million, respectively, and our net losses for the six months ended June 30, 2019 and 2018 were $14.4 million and 10.2 million, respectively. As of June 30, 2019, we had an accumulated deficit of $61.7 million, primarily as a result of research and development and general and administrative expenses.

We do not expect to generate product revenue unless and until we obtain marketing approval for and commercialize a product candidate, and we cannot assure you that we will ever generate significant revenue or profits.

        We have funded our operations to date primarily with proceeds from the sale of preferred stock, proceeds from our multi-year collaboration and development agreement with Eli Lilly and Company, or Lilly, and proceeds from our IPO. From our inception through June 30, 2019, we received gross proceeds of $164.4 million through private placements of preferred stock and an upfront payment of $25.0 million in connection with our agreement with Lilly, or the Lilly Agreement. In April 2018, we received gross proceeds of $31.0 million from the sale and issuance of shares of our Series A-3 Preferred Stock, and in November 2018, we received gross proceeds of $93.4 million from the sale and issuance of shares of our Series B Preferred Stock, including $15.0 million from Lilly as described below.

        In November 2018, we entered into a multi-year research and development collaboration agreement with Lilly, or the Lilly Agreement, pursuant to which we will use our FIND-IO platform to identify novel oncology targets for additional collaborative research and drug discovery by us and Lilly. Under this agreement, we granted Lilly the exclusive option to obtain worldwide exclusive licenses to research, develop, manufacture and commercialize multiple compounds and products directed to oncology targets identified through our research collaboration. In addition, Lilly granted us the exclusive option to obtain worldwide exclusive licenses to research, develop, manufacture and commercialize an equal number of compounds and products directed to oncology targets for which Lilly does not exercise its option. The Lilly Agreement will expire upon the earlier of the exercise of all options granted to Lilly or four years from the date of the agreement.

        We received an upfront payment of $25.0 million in cash and an equity investment of $15.0 million from Lilly upon entering into the Lilly Agreement, and we are eligible for quarterly research and development support payments during a portion of the term of the Lilly Agreement, option exercise payments upon option exercises by Lilly and milestone payments in an aggregate of up to $1.4 billion, as well as mid to high single-digit royalty payments on net sales for all products directed to each target optioned by Lilly. The milestone payment amount assumes that Lilly exercises all of the options available to it, as well as the successful achievement of all clinical development and sales milestones for each target optioned by Lilly pursuant to the Lilly Agreement. If Lilly obtains approval in additional indications in different therapeutic areas, then additional amounts may become due. Upon our exercise of an option with respect to a given target, we will owe Lilly option exercise, milestone and royalty payments in amounts equivalent to a portion of the amounts payable by Lilly were Lilly to exercise an option. For more information on the Lilly Agreement, see "Business—Our Collaboration Agreements—Research and Development Collaboration with Lilly." We expect to record collaboration and licensing revenue beginning in 2019 related to the Lilly Agreement. We expect to recognize revenue from this agreement, including deferred revenue included on our balance sheets as of December 31, 2018 of $26.7 million, which consists of the $25.0 million upfront payment plus $1.7 million attributed as a premium on the proceeds from Lilly's investment in shares of our Series B-3 Preferred Stock, on a proportional performance basis over the term of the Lilly Agreement.

        In December 2015, we entered into a license agreement with Yale University, or the Yale Agreement, pursuant to which we obtained a license to products that either incorporate certain licensed patents used in the discovery of targets or arise out of research and development of Dr. Chen's laboratory at Yale, including S15. We are obligated to pay Yale low single-digit royalties on sales of products, including NC318, that are either covered by the patents licensed to us under the Yale Agreement or arise out of Dr. Chen's laboratory, subject to minimum annual royalty payments in the low to mid hundreds of thousands of dollars. Until we are required to pay royalties under the Yale Agreement, we must also pay an annual license maintenance fee in the mid to high tens of thousands of dollars. In addition, we are obligated to pay Yale milestone payments in an aggregate of up to approximately $3.0 million per product.

        In connection with the Yale Agreement, we also entered into a corporate sponsored research agreement with Yale, or the SRA, in which we agreed to provide an aggregate of up to $12.4 million to fund a research program under the direction and supervision of Dr. Chen aimed at discovering new targets for immunomedicines. As of December 31, 2018, we have made payments in an aggregate of $7.4 million under the SRA, including $2.5 million in the year ended December 31, 2018. Pursuant to the SRA, we have the option to add any patents invented pursuant to the research program as a licensed patent under the Yale Agreement and the right to obtain a royalty-bearing, exclusive, worldwide license to any such patents.

        On May 13, 2019, we closed our IPO, in which we sold 5,750,000 shares of common stock, at a public offering price of $15.00 per share, for aggregate gross proceeds of $86.3 million. The net offering proceeds to us were approximately $77.0 million after deducting underwriting discounts and commissions of $6.0 million and offering expenses of $3.4 million. See Note 1 to our unaudited condensed financial statements included elsewhere in this prospectus for more information.

        As of June 30, 2019, we had cash and cash equivalents, excluding restricted cash, of $192.7 million. We believe that our existing cash and cash equivalents, together with the net proceeds from this offering, will be sufficient to fund our planned operations into                . We have based this estimate on assumptions that may prove to be incorrect, and we could use our available capital resources sooner than we currently expect.

        We expect to incur substantial expenditures in the foreseeable future as we advance our product candidates through clinical development, the regulatory approval process and, if approved, commercialization, and as we expand our pipeline through research and development activities related to our FIND-IO platform and discovery programs. Specifically, in the near term, we expect to incur substantial expenses relating to our ongoing and planned Phase 1/2 clinical trials of NC318, preclinical studies and our planned Phase 1/2 clinical trial of NC410 and other research and development activities. We expect to incur significantly increased costs as a result of operating as a public company, including significant legal, accounting, investor relations and other expenses that we did not incur as a private company.

        We will need substantial additional funding to support our continuing operations and to pursue our development strategy. Until such time as we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our operations through a combination of public or private equity offerings, debt financings, marketing and distribution arrangements, other collaborations, strategic alliances and licensing arrangements. Adequate funding may not be available to us on acceptable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we may be required to delay, limit, reduce or terminate preclinical studies, clinical trials, or other research and development activities or one or more of our development programs.

Components of Our Results of Operations

Revenue

        For the three and six months ended June 30, 2019, we recognized $1.4 million and $2.8 million, respectively, in revenue under the Lilly Agreement. Through June 30, 2019, we have not generated any revenue from product sales. Through December 31, 2018, we had not generated any revenue from product sales or otherwise.

        For additional information about our revenue recognition policy, see Note 2 to our audited financial statements included elsewhere in this prospectus. For the foreseeable future, we expect all of our revenue will be generated from the Lilly Agreement.

Operating Expenses

        Research and development expenses consist primarily of costs incurred for our discovery efforts, research activities, development and testing of our product candidates as well as for clinical trials, including:

        We expense research and development costs as incurred. Our expenses related to clinical trials are based on actual costs incurred and estimates of other incurred costs. These estimated costs are based on several factors, including patient enrollment and related expenses at clinical investigator sites, contract services received, consulting agreement costs and efforts expended under contracts with research institutions and third-party contract research organizations that conduct and manage clinical trials on our behalf. We generally accrue estimated costs related to clinical trials based on contracted amounts applied to the level of patient enrollment and other activity according to the protocol. If future timelines or contracts are modified based on changes in the clinical trial protocol or scope of work to be performed, we would modify our estimates of accrued expenses accordingly on a prospective basis. Historically, any such modifications have not been material.

        Due to the early-stage nature of our programs and the discovery-related nature of our efforts, we do not track costs on a program-by-program basis other than costs incurred for the Lilly Agreement. However, as our current and future product candidates proceed along a development path and in clinical trials, we intend to track the costs of each program. We measure costs incurred under the Lilly Agreement as an input to recording revenue from the Lilly Agreement.

        Research and development activities are central to our business model. We expect that our research and development expenses will continue to increase substantially for the foreseeable future as we advance our product candidates through development, including conducting our Phase 1/2 clinical trial of NC318 and conducting preclinical studies and a Phase 1/2 clinical trial of NC410, and as we expand our pipeline through research and development activities related to our FIND-IO platform and discovery programs.

        We cannot determine with certainty the duration and costs of future clinical trials of NC318, NC410 or any other product candidate we may develop or if, when or to what extent we will generate revenue from the commercialization and sale of any product candidate for which we may obtain marketing approval. We may never succeed in obtaining marketing approval for any product candidate. The duration, costs and timing of clinical trials and development of NC318, NC410 and any other product candidate we may develop will depend on a variety of factors, including:

78


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

        A change in the outcome of any of these variables with respect to the development of a product candidate could lead to a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in our clinical trials due to patient enrollment or other reasons, we would be required to expend significant additional financial resources and time to complete clinical development for any such product candidate.

        General and administrative expenses consist primarily of personnel-related costs, including payroll and stock-based compensation, for personnel in executive, finance, human resources, business and corporate development and other administrative functions, professional fees for legal, intellectual property, consulting and accounting services, rent and other facility-related costs, depreciation and other general operating expenses not otherwise classified as research and development expenses. General and administrative expenses also include all patent-related costs incurred in connection with filing and prosecuting patent applications, which are expensed as incurred.

        We anticipate that our general and administrative expenses will increase substantially during the next few years as a result of staff expansion and additional occupancy costs, as well as costs associated with being a public company, including higher legal and accounting fees, investor relations costs, higher insurance premiums and other compliance costs associated with being a public company.

Other Income, Net

        Other income, net consists primarily of interest income earned on our short-term investments in U.S. Treasury obligations and payment of interest on our term loan with a commercial bank, or the Term Loan.

Revenue from Research and Development Arrangement

        Revenue was $1.4 million and $0 million for the three months ended June 30, 2019 and 2018, respectively and $2.8 million and $0 million for the six months ended June 30, 2019 and 2018, respectively. The increase in revenue is related to the recognition of a portion of the upfront consideration under the Lilly Agreement and the premium on the proceeds from Lilly's investment in shares of our Series B-3 Preferred Stock.

Research and Development Expenses

        Research and development expenses for the three months ended June 30, 2019 increased by $3.2 million to $7.6 million compared to $4.4 million for the three months ended June 30, 2018. The increase was driven primarily by $0.9 million in personnel-related costs due to an increase in headcount. Other significant components of the increase in research and development expenses included the following: $0.8 million in lab supplies and services for NC318, NC410, other early-stage programs and discovery activities; $0.7 million in clinical research costs related to advancing NC318; a $0.5 million payment to Yale University in connection with the closing of our IPO; and $0.1 million in depreciation expense.

        Research and development expenses for the six months ended June 30, 2019 increased by $5.5 million to $14.2 million compared to $8.6 million for the six months ended June 30, 2018. The increase was driven primarily by $1.6 million in personnel-related costs due to an increase in headcount. Other significant components of the increase in research and development expenses included the following: $1.5 million in clinical research costs related to advancing NC318; $1.3 million in lab supplies and services for NC318, NC410, other early-stage programs and discovery activities; a $0.5 million payment to Yale University in connection with the closing of our IPO; and $0.3 million in payments pursuant to the SRA and other sponsored research agreements.

General and Administrative

        General and administrative expenses for the three months ended June 30, 2019 increased by $1.8 million to $2.7 million as compared to $0.9 million for the three months ended June 30, 2018. The increase was driven primarily by increases, in connection with our IPO, of $0.7 million for professional fees

related to legal, finance and audit services, public relations, compensation and investor relations support, $0.3 million in insurance expenses and $0.2 million in personnel-related costs due to an increase in headcount as well as, $0.5 million for an unrestricted gift to an academic lab.

        General and administrative expenses for the six months ended June 30, 2019 increased by $2.7 million to $4.4 million as compared to $1.7 million for the six months ended June 30, 2018. The increase was driven primarily by increases, in connection with our IPO, of $1.3 million for professional fees related to legal, finance and audit services, public relations, compensation and investor relations support, $0.4 million in personnel-related costs due to an increase in headcount and $0.3 million in insurance expenses, in connection with our IPO, as well as, $0.5 million for an unrestricted gift to an academic lab.

Other Income, Net

        Other income, net for the three months ended June 30, 2019 increased by $0.6 million to $0.7 million from $69,000 for the three months ended June 30, 2018. The increase was driven primarily by interest income earned on higher cash balances, partially offset by interest expense related to the Term Loan.

        Other income, net for the six months ended June 30, 2019 increased by $1.3 million to $1.4 million from $82,000 for the six months ended June 30, 2018. The increase was driven primarily by interest income earned on higher cash balances, partially offset by interest expense related to the Term Loan.

        General and administrative expenses for the year ended December 31, 2018 increased by $0.8 million to $3.4 million as compared to $2.6 million for the year ended December 31, 2017. The increase was driven primarily by an increase of $0.2 million in personnel-related costs due to an increase in headcount and an increase of $0.3 million for professional fees related to legal and audit services.

        Other income, net for the year ended December 31, 2018 increased by $0.3 million to $0.4 million from $80,000 for the year ended December 31, 2017. The increase was driven primarily by interest income earned on the proceeds of our Series A and B Preferred Stock financing, partially offset by interest expense related to the Term Loan.

Liquidity and Capital Resources

        We have financed our operations primarily through private placements of preferred stock, proceeds pursuant to the Lilly Agreement and our IPO. On May 13, 2019, we closed our IPO in which we sold 5,750,000 shares of common stock, at a public offering price of $15.00 per share, for aggregate gross proceeds of $86.3 million. The net offering proceeds to us were approximately $77.0 million after deducting underwriting discounts and commissions of $6.0 million and offering expenses of $3.4 million. Since inception, we have received aggregate gross proceeds of $164.4 million from the sale and issuance of shares of our preferred stock. In addition, in November 2018, we received an upfront payment of $25.0 million in cash from Lilly pursuant to the Lilly Agreement. Our cash and cash equivalents are held in money market funds and U.S. Treasury obligations.

        As of June 30, 2019, our principal source of liquidity was cash and cash equivalents of $192.7 million. We believe that the net proceeds from this public offering, together with our existing cash and cash equivalents, will be sufficient to fund our planned operations into .

        In addition, in April 2016, we entered into the Term Loan to finance laboratory equipment purchases. In January 2019, we amended the Term Loan to increase our borrowing capacity from $1.0 million to $5.0 million. As amended, the Term Loan matures in January 2023. Our obligations under the Term Loan are secured by a security interest in our certificates of deposit, money market accounts, cash, securities, investment property and deposit or investment accounts. The Term Loan bears interest at a rate equal to the greater of (i) the prime rate less 1.0% and (ii) 4.25% and is subject to mandatory prepayment upon the occurrence of specified events, including failure to pay the Term Loan when due, uncured breach, bankruptcy or dissolution. Under the Term Loan, we will make interest-only payments through January 2020 and 36 equal monthly payments of principal plus accrued interest thereafter through January 2023. As of June 30, 2019, our outstanding borrowings under the Term Loan were $5.0 million.

        We will continue to require additional capital to develop our product candidates and fund operations for the foreseeable future. We may seek to raise capital through sale of equity, debt financings, strategic alliances and licensing arrangements. Adequate additional funding may not be available to us on acceptable terms or at all. If we fail to raise capital or enter into such agreements as and when needed, we may have to significantly delay, scale back or discontinue the development of our product candidates or delay our efforts to expand our pipeline of product candidates. We anticipate that we will need to raise substantial additional capital, the requirements of which will depend on many factors, including:

82

Pursuant to 17 C.F.R. Section 200.83

        If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Any future debt financing into which we enter may impose upon us additional covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments and engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. If we are unable to raise additional funds when needed, we may be required to delay, reduce or terminate some or all of our development programs and clinical trials. We may also be required to sell or license to others rights to our product candidates in certain territories or indications that we would prefer to retain for ourselves.

        See the section entitled "Risk Factors" for additional risks associated with our substantial capital requirements.

        Net cash used in operating activities was $17.7 million for the six months ended June 30, 2019, which was primarily due to our net loss of $14.4 million. Net cash used in operating activities was $9.8 million for the six months ended June 30, 2018, which was primarily due to our net loss of $10.2 million in connection with our research and development activities, partially offset by timing of cash payments. The amount of cash used in operating activities in any period is influenced by the timing of cash payments for research-related expenses.

        Net cash provided by operating activities was $8.0 million for the year ended December 31, 2018, which was primarily due to deferred revenue, including the $25.0 million upfront payment pursuant to the Lilly Agreement, as well as a non-cash charge for depreciation and amortization and the timing of cash payments, partially offset by our net loss of $22.8 million as we continued our research and development activities. Net cash used in operating activities was $12.5 million for the year ended December 31, 2017, which was primarily due to our net loss of $15.5 million in connection with our research and development activities, partially offset by a $1.6 million increase in accrued liabilities caused by the growth of our business as well as timing of cash payments. The amount of cash used in operating activities in any period is influenced by the timing of cash payments for research-related expenses.

        Cash used in investing activities for the six months ended June 30, 2019 and 2018 was $2.1 million and $0.9 million, respectively, which consisted in each case primarily of purchases of property and equipment.

        Cash used in investing activities for the years ended December 31, 2018 and 2017 was $3.1 million and $8.7 million, respectively, which consisted in each case primarily of purchases of laboratory equipment.

        Cash provided by financing activities was $81.8 million for the six months ended June 30, 2019, which consisted primarily of net proceeds from the Company's public offering. Cash provided by financing activities was $30.8 million for the six months ended June 30, 2018, which consisted of gross proceeds from the sale and issuance of shares of our Series A-3 Preferred Stock.

        Cash provided by financing activities was $121.4 million for the year ended December 31, 2018, which consisted primarily of net proceeds from the issuance and sale of shares of our Series A and B Preferred Stock, partially offset by issuance costs, deferred offering costs and payments under the Term Loan.

        Cash provided by financing activities was $24.9 million for the year ended December 31, 2017, which consisted primarily of net proceeds from the issuance and sale of shares of our Series A Preferred Stock, partially offset by payments under the Term Loan.

2018. The term of the lease commenced in February 2016 and expires in August 2025. Under the terms of the lease as of December 31, 2018, we will have lease obligations aggregating $2.3 million through 2025.

        The contractual obligations table does not include any potential contingent payments upon the achievement by us of clinical, regulatory and commercial events, as applicable, or royalty payments that we may be required to make under license agreements we have entered into with various entities pursuant to which we have in-licensed intellectual property, including our license agreements with Lilly and Yale and our SRA with Yale. We excluded the contingent payments given that the timing and amount (if any) of any such payments cannot be reasonably estimated at this time. See "Business—Our Collaboration Agreements" for additional information.

        We enter into contracts in the normal course of business with third-party contract organizations for clinical trials, non-clinical studies and testing, manufacturing and other services and products for operating purposes. These contracts generally provide for termination following a certain period after notice, and therefore we believe that our non-cancelable obligations under these agreements are not material.

        There have been no material changes outside the ordinary course of business to our contractual obligations during the six month period ended June 30, 2019, as compared to those set forth above. See Notes 6 and 7 to our unaudited condensed financial statements included elsewhere in this prospectus for a discussion of our leases and the Term Loan, respectively.

Critical Accounting Policies, Significant Judgments and Use of Estimates

        Our financial statements have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods. The most significant assumptions used in the financial statements are the underlying assumptions used in revenue recognition and valuing share-based compensation, including the fair value of our common stock in periods before our IPO. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management's judgments and estimates.

        While our significant accounting policies are described in the notes to our financial statements, we believe that the following critical accounting policies are most important to understanding and evaluating our reported financial results.

Research and Development Expenses

        Expenditures, including payroll, contractor expenses and supplies, for research and development of product candidates are expensed as incurred. Development costs incurred by third parties are expensed as the contracted work is performed. Where contingent milestone payments are due to third parties under research and development arrangements, the milestone payment obligations are expensed when the milestone results are probable of being achieved.

Stock-Based Compensation

        We account for stock-based compensation, including stock options and restricted stock units, based on the fair value of the award as of the grant date. We utilize the Black-Scholes option-pricing model as the method for estimating the fair value of our stock option grants. The Black-Scholes option-pricing model

85


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

requires the use of highly subjective and complex assumptions, including the options' expected term and the price volatility of the underlying stock. The fair value of the portion of the award that is ultimately expected to vest is recognized as compensation expense over the award's requisite service period. We recognize stock-based compensation to expense using the straight-line method. If there are any modifications or cancelations of stock-based awards, we may be required to accelerate, increase or decrease any remaining unrecognized stock-based compensation expense.

        Stock-based compensation expense, net of estimated forfeitures, is reflected in the statements of operations and comprehensive loss as follows (in thousands):

 
  Six Months Ended
June 30,
  Year Ended
December 31,

Research and development expense

  $ 300   $ 21   $ 85   $ 35  

General and administrative expense

  $ 495   $ 27   $ 178   $ 40  

Total stock-based compensation expense

  $ 795   $ 48   $ 263   $ 75  

        As of June 30, 2019, total unamortized stock-based compensation was $7,127,035.

        The intrinsic value of all outstanding stock options as of June 30, 2019 was $20.7 million.

        Before our IPO, there was no public market for our common stock to date and the estimated fair value of our common stock was determined by our board of directors as of the date of each option grant, with input from management, considering our most recently available third-party valuations of common stock, and our board of directors' assessment of additional objective and subjective factors that it believed were relevant and which may have changed from the date of the most recent valuation through the date of the grant. These third-party valuations were performed in accordance with the guidance outlined in the American Institute of Certified Public Accountants' Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. Our common stock valuations were prepared using an option pricing method, or OPM, which used market approaches to estimate our enterprise value. The OPM treats common stock and preferred stock as call options on the total equity value of a company, with exercise prices based on the value thresholds at which the allocation among the various holders of a company's securities changes. Under this method, the common stock has value only if the funds available for distribution to stockholders exceeded the value of the preferred stock liquidation preferences at the time of the liquidity event, such as a strategic sale or a merger. A discount for lack of marketability of the common stock is then applied to arrive at an indication of value for the common stock.

        Since the closing of our IPO, our board of directors has determined the fair value of our common stock based on the closing price of our common stock on the Nasdaq Global Select Market as reported on the date of grant.

Income Taxes

        We use the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax base. Deferred tax assets and liabilities, which relate primarily to the carrying amount of our property and equipment and our net operating loss carryforwards, are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax expense or benefit is the result of changes in the deferred tax assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets where, based upon the

86


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

available evidence, management concludes that it is more likely than not that the deferred tax assets will not be realized. In evaluating our ability to recover deferred tax assets, we consider all available positive and negative evidence, including our operating results, ongoing tax planning and forecasts of future taxable income on a jurisdiction-by-jurisdiction basis. Because of the uncertainty of the realization of deferred tax assets, we have recorded a full valuation allowance against our deferred tax assets.

        Reserves are provided for tax benefits for which realization is uncertain. Such benefits are only recognized when the underlying tax position is considered more likely than not to be sustained on examination by a taxing authority, assuming they possess full knowledge of the position and facts. Interest and penalties related to uncertain tax positions are recognized in the provision of income taxes; however, we currently have no interest or penalties related to uncertain income tax benefits.

        As of December 31, 2018, our gross deferred tax assets were $15.8 million. Due to our lack of earnings history and uncertainties surrounding our ability to generate future taxable income, the net deferred tax assets have been fully offset by a valuation allowance. The deferred tax assets were primarily comprised of federal and state tax net operating losses, or NOLs. Utilization of NOLs may be limited by the "ownership change" rules, as defined in Section 382 of the Internal Revenue Code of 1986, as amended. Similar rules may apply under state tax laws. Our ability to use our remaining NOLs may be further limited if we experience an ownership change in connection with this offering, future offerings or as a result of future changes in our stock ownership.

Off-Balance Sheet Arrangements

        Since our inception, we have not engaged in any off-balance sheet arrangements, as defined in the rules and regulations of the U.S. Securities and Exchange Commission.

JOBS Act Accounting Election

        The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, permits an "emerging growth company" such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to take advantage of this extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

        For so long as we remain an emerging growth company, we are permitted and intend to rely on certain exemptions from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002. We will remain an emerging growth company until the earliest of (i) December 31, 2024, (ii) the last day of the first fiscal year in which we have total annual gross revenues of at least $1.07 billion, (iii) the last day of the first fiscal year in which the market value of our common stock that is held by non-affiliates exceeds $700.0 million on June 30th and (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

BUSINESS

Overview

        We are a clinical-stage biopharmaceutical company committed to discovering and developing novel, first-in-class immunomedicines to treat cancer and other immune-related diseases by restoring normal immune function. We view the immune system holistically and, rather than target one specific immune cell type, we focus on understanding biological pathways, the interactions of cells and the role each interaction plays in an immune response. Through our proprietary Functional, Integrated, NextCure Discovery in Immuno-Oncology, or FIND-IO, platform, we study various immune cells to discover and understand targets and structural components of immune cells and their functional impact in order to develop immunomedicines. We are focused on patients who do not respond to current therapies, patients whose cancer progresses despite treatment and patients with cancer types not adequately addressed by available therapies. We are committed to discovering and developing first-in-class immunomedicines, which are immunomedicines that use new or unique mechanisms of action to treat a medical condition, for these patients. Our lead product candidate, NC318, is a first-in-class immunomedicine targeting a novel immunomodulatory receptor called Siglec-15, or S15. In October 2018, we initiated a Phase 1/2 clinical trial of NC318 in patients with advanced or metastatic solid tumors. We completed enrollment of the Phase 1 portion of this trial in August 2019 and preliminary data from the Phase 1 portion will be presented in November 2019 at the Society for Immunotherapy of Cancer, or SITC, annual meeting. We began enrolling patients in the Phase 2 portion of the trial in October 2019 and expect to announce initial data from the Phase 2 portion by the end of 2020. Our second product candidate, NC410, is a novel immunomedicine designed to block immune suppression mediated by an immune modulator called Leukocyte-Associated Immunoglobulin-like Receptor 1, or LAIR-1. We expect to submit an investigational new drug application, or IND, to the U.S. Food and Drug Administration, or FDA, for NC410 in the first quarter of 2020.

        Our approach to identifying targets for new immunomedicines is based on our FIND-IO platform. FIND-IO embodies a rational approach to the discovery of novel cell surface and secretory molecules that drive functional immune responses. We use our immunology knowledge, experience, capabilities and tools we have developed, including our FIND-IO platform, to support our discovery efforts. We are working to discover novel targets that play a key role in mediating immune dysfunctions that allow tumors to evade the immune system. We are seeking to identify and develop immunomedicines that counteract these outcomes and to further validate and advance our product candidates. We have identified multiple novel targets using our FIND-IO platform, including those for which certain of our research programs are being designed to target. In addition, the immunosuppressive properties of S15, the target of NC318, were discovered using a predecessor of our FIND-IO platform.

        NC318, our lead immunomedicine program, is a monoclonal antibody targeting S15, which is expressed on highly immunosuppressive cells called M2 macrophages and on tumor cells. The immunosuppressive properties of S15 were discovered in 2015 at Yale University by our scientific founder Dr. Lieping Chen. Dr. Chen was also the first to discover a molecule he called B7-H1, which is now more widely known as PD-L1, or programmed cell death protein ligand 1, which is the ligand for PD-1, or programmed cell death 1. In preclinical research, we and others have observed that S15 promotes suppression of T cell proliferation and negatively regulates T cell function. NC318 is designed to block this S15-mediated immune suppression and restore T cell function and anti-tumor immunity in the tumor microenvironment, or TME, which we believe will reduce and kill tumors. We believe NC318 has the potential to treat multiple cancer indications because S15 is expressed in multiple tumor types and has a unique ability to modulate immune responses in the TME. In addition, because S15 and PD-L1 expression in tumors generally appear to be non-overlapping, we believe NC318 may be well suited to treat patients who are not responding to PD-1/PD-L1 directed cancer therapies. We are initially evaluating NC318 for the treatment of advanced or metastatic solid tumors, including ovarian cancer, non-small cell lung cancer,

or NSCLC, head and neck squamous cell carcinoma, or HNSCC, and triple-negative breast cancer, or TNBC.

        NC410, our second immunomedicine program, is a fusion protein designed to block immune suppression mediated by LAIR-1. LAIR-1 is expressed on T cells and antigen-presenting cells, known as dendritic cells, that present tumor antigens to immune cells in order to generate immune responses. The binding of LAIR-1 to collagen or C1q results in loss of immune function in the TME and a reduction in T cell function and dendritic cell activity. By blocking the binding of LAIR-1, NC410 can promote T cell function and dendritic cell activity, which could result in anti-tumor immune responses that eliminate cancer cells. We are currently conducting IND-enabling studies for NC410 and expect to submit an IND and initiate a Phase 1/2 clinical trial in patients with advanced or metastatic solid tumors in the first quarter of 2020. We are currently focused on opportunities for NC410 in ovarian cancer, NSCLC and renal cancer.

        The advancement of cancer to late stages indicates a failure of the immune system to mount an effective anti-tumor immune response. Immuno-oncology, which focuses on stimulating the immune system to respond to cancer and includes checkpoint inhibitors targeting PD-L1, PD-1 and cytotoxic T-lymphocyte antigen-4, or CTLA-4, is one of the most significant advances in the history of cancer treatment. In 2011, the first checkpoint inhibitor was approved, and today, despite only a modest breadth of efficacy, this class of therapies is estimated to have had global sales of more than $17 billion in 2018 and is predicted to reach more than $33 billion in global sales by 2022. However, despite the recent success of checkpoint inhibitors, efficacy has been limited. It is estimated that up to 60% to 70% of cancer patients, including those with melanoma, renal cell cancer, colorectal cancer, NSCLC, urothelial cancer and HNSCC, do not respond to single-agent therapy with checkpoint inhibitors. In addition, some patients develop resistance after initial treatment with these therapies. As a result, the standard of care in cancer today leaves many patients underserved. We believe broader efficacy and more meaningful clinical responses in oncology may be obtained by focusing on the TME.

        We are using our FIND-IO platform as our discovery engine to identify targets and develop immunomedicines that restore normal immune function in the TME through novel mechanisms of action. Since our founding in 2015, we have developed, industrialized and optimized our FIND-IO platform based on the immunological expertise of our management team and the scientific leadership of Dr. Chen. Our approach in creating the FIND-IO platform, and how we apply it, reflects our belief in the importance of understanding biological pathways of all cells in the immune system and restoring normal immune function. The platform uses our proprietary approaches to assess the suppressive or stimulatory function of immune pathways in T cells and other immune cells, as measured by effects on proliferation or induction of molecules known to impact immune responses, such as cytokines, which are signaling molecules secreted by cells in the immune system that mediate and regulate immunity and inflammation. We study primary immune cells from healthy donors and from patients with various diseases, as well as established cell lines from immune and non-immune cell lineages, including T cell subsets, monocytes, macrophage subpopulations and cancer cell lines. In oncology, we are using the FIND-IO platform to discover immunomedicines with the potential to intervene or modulate interactions of immune cells within the TME to restore anti-tumor activity. We are also expanding the functional screening approach of our FIND-IO platform for the identification of novel targets in other serious illnesses outside of oncology, including autoimmune, inflammatory and neuro-inflammatory diseases.

        In November 2018, we entered into a multi-year collaboration agreement with Eli Lilly and Company, or Lilly, focused on the discovery and development of immunomedicines for oncology using our FIND-IO platform. The collaboration seeks to discover novel cancer targets utilizing our platform and provides that we and Lilly will each receive options to exclusively develop antibodies resulting from the collaboration. In connection with the agreement, or the Lilly Agreement, we received an upfront payment of $25.0 million in cash and an equity investment of $15.0 million and are eligible to receive development and regulatory milestones and sales milestones in an aggregate of up to $1.4 billion, as well as royalty payments.

        We have assembled an experienced management team to execute on our mission to create novel immunomedicines. Our scientific founder and members of our management team collectively have extensive experience in drug discovery and product development and are leaders in the immuno-oncology field. Members of our management team have experience discovering, developing, manufacturing and commercializing biologics, including some of the earliest approved monoclonal antibodies, such as Synagis, as well as some of the first immune checkpoint inhibitor monoclonal antibodies and fusion proteins targeting the PD-1/PD-L1 pathway and CTLA-4, including Yervoy. Within three years, we advanced our company from formation to antibody generation to the clinic, and constructed a manufacturing facility that complies with current good manufacturing practice, or cGMP, and that we have used to manufacture our preclinical and clinical drug supply.

        Members of our management team have a longstanding relationship with our scientific founder Dr. Chen, who is the United Technologies Corporation Professor in Cancer Research and Professor of Immunobiology, of Dermatology and of Medicine (Medical Oncology) at Yale, and the Co-Director of the Cancer Immunology Program at Yale Cancer Center. Dr. Chen was the first to discover PD-L1, and to show that it is expressed by multiple tumor types and its activity can cause the death of T cells, preventing those T cells from eliminating cancer cells. He also showed that blocking the interaction between PD-1 and PD-L1 with monoclonal antibodies improved the immune system's ability to eliminate tumors. Dr. Chen's work provided an important foundation for the subsequent development of immunotherapies that enable more effective immune treatments against cancer. Since then, his laboratory has identified and characterized various molecules in two of the major families of immune modulating proteins, the B7-CD28 and the tumor necrosis factor, or TNF, receptor/ligand superfamilies, and elucidated their interactions and functions in controlling immune responses. The immunosuppressive properties of S15, the target of our lead product candidate, NC318, were discovered in Dr. Chen's lab using a predecessor of our FIND-IO platform. We continue to collaborate with Dr. Chen on discovering novel immunomedicines through an exclusive sponsored research agreement with Yale.

        We believe the combination of our team's capabilities and focus on understanding the biological pathways of the immune system, our product development expertise and manufacturing infrastructure, our partnership with Lilly and our relationship with Dr. Chen and Yale positions us to build a sustainable portfolio of first-in-class immunomedicines.

Immuno-Oncology Background

        The immune system has powerful biological mechanisms to defend and protect the body from pathogens, such as viruses, parasites and bacteria. It also provides surveillance against cancers by recognizing and responding to antigens that are uniquely or highly expressed on cancer cells. In cancer, complex interactions between immune cells and growing tumor cells can prevent an immune response by blocking cellular interactions, resulting in immunosuppression in the TME. This phenomenon, referred to as immune evasion, is a hallmark of cancer where the tumor can prevent tumor-specific immune cells called T cells from functioning within the TME or gaining access to the tumor site, which allows the tumor to continue to grow, leading to disease progression. Tumors in advanced cancer have multiple mechanisms of evasion in the TME that can differ from tumor to tumor.

        The TME is the cellular environment in which the tumor exists and encompasses the surrounding blood vessels, a variety of immune cells, fibroblasts, bone marrow-derived inflammatory cells, lymphocytes, signaling molecules and the extracellular matrix, or ECM. Immune cell types in the TME include T cells, natural killer, or NK, cells, dendritic cells, macrophages, suppressive myeloid cells and neutrophils. The tumor and the surrounding microenvironment interact constantly. Tumors and immune cells can express co-inhibitory proteins known as checkpoints that lead to immune tolerance by the tumor and/or immune cells, allowing the tumor to grow by evading the host immune response. In addition to modulating immune function, immune cells in the TME can also promote a pro-tumorigenic environment that fosters the growth and evolution of cancer cells.

        Remodeling the TME and overcoming its immunosuppressive properties is a major focus of cancer research and drug development. Checkpoint inhibitors are a drug class designed to counteract certain tumor defenses against the immune system. Currently approved checkpoint inhibitors were developed for the treatment of cancer based on the belief that inactivation of the immune system by checkpoints could be reversed to reactivate the immune system to recognize and attack the tumor. Therapies against checkpoints, such as PD-L1, PD-1 and CTLA-4, have produced impressive results in the clinic across an array of cancers and have been approved for several malignancies. However, despite the recent success of these checkpoint inhibitors, efficacy has been limited. It is estimated that up to 60% to 70% of cancer patients, including those with melanoma, renal cell cancer, colorectal cancer, NSCLC, urothelial cancer

and HNSCC, do not respond to single-agent therapy with checkpoint inhibitors. Many of the patients who are non-responders possess so called "cold" tumors that do not contain meaningful numbers of T cells that recognize their tumors. In addition, some patients develop resistance after initial treatment with these checkpoint inhibitors. This limited efficacy highlights the importance of our effort to identify novel targets and molecular pathways responsible for tumor immune evasion mechanisms that we believe will work independently from current targets for cancer immunotherapy.

Our Approach to Developing Immunomedicines for Cancer

        Our approach to identifying targets for new immunomedicines in cancer is based on the combination of our FIND-IO platform, our immunological expertise and our belief in the importance of understanding biological pathways and the normal function of the immune system in the TME. Rather than focusing on a specific type of immune cell, we are targeting molecules that modulate the immune system in ways that we believe may provide new treatment opportunities for patients that are differentiated from currently marketed targeted therapies as well as those in development. Our primary goal is to develop immunomedicines that increase response rates, efficacy and durable overall survival among patients who do not respond to current therapies, patients whose cancer progresses despite treatment and patients with cancer types that are not adequately addressed by currently available therapies. We design our product candidates either to restore the normal effects of the immune system to promote elimination of the tumors or to counteract tumor immune evasion mechanisms.

        Our FIND-IO platform applies a function-based screening approach to identify human proteins and to determine whether those proteins alter or stop an immune response resulting in immune evasion. The platform is designed to identify novel cell surface molecular interactions that drive functional immune responses. Our FIND-IO platform broadly and quantitatively evaluates interactions between relevant protein components and different cellular types over time in order to identify novel targets that either increase or decrease immune-related functional responses associated with desired immune responses against tumors. By identifying novel immune modulators through the FIND-IO platform, we aim to develop next-generation immunomedicines that restore normal immune function in the TME.

        To create our FIND-IO platform, we industrialized, expanded and optimized the T Cell Activity Array, or the TCAA, a predecessor of the FIND-IO platform that Dr. Chen used to discover the immunosuppressive properties of S15. Our work in developing the FIND-IO platform beyond the TCAA includes using different and expanded gene libraries, adding biological pathways and reporters, expanding immune cell types and, most importantly, increasing the repertoire of functional assay readouts. We also broadened the platform to look at signaling within both the immune cell and the cell expressing the library gene. By transfecting cells with library genes, which encode membrane-bound or soluble proteins, FIND-IO is designed to determine whether the genes have signaling functions when interacting with an immune cell.

        Our FIND-IO technology includes proprietary approaches to functionally assess immune pathways in both primary immune cells and established cell lines from immune lineages, including T cell subsets, monocytes, macrophage subpopulations, dendritic cells, cancer cell lines and cells isolated from diseased patients. This platform allows us to identify proteins that can be targeted with novel immunomedicines to repair and maintain anti-tumor immunity. By focusing on understanding the TME in oncology, we believe we can identify multiple new positive and negative modulators of immune cells, including T cells, NK cells, macrophages and myeloid-derived suppressor cells. As shown in the figure below, our product candidates target a variety of cell types in the immune system. For example, NC318 targets macrophages and tumor cells and prevents suppressive myeloid cells from negatively regulating T cells. NC410 targets the negative signaling of dendritic cells, macrophages and T cells mediated by the binding of LAIR-1 to its ligands collagen and C1q. We also have earlier stage discovery programs that are investigating the negative effects of NK cells and other immune cells in the TME on T cells.

NC318

        NC318 is a monoclonal antibody that binds specifically to human S15 with high affinity. We have observed in preclinical studies that blocking S15 improved the immune response in multiple animal models. We believe that NC318 may help promote an effective anti-tumor immune response by targeting multiple cell types in the TME that express S15, including macrophages and S15-positive tumor cells. Based on the results of our preclinical studies, we initiated a Phase 1/2 clinical trial of NC318 in patients with advanced or metastatic solid tumors in October 2018. We completed enrollment of the Phase 1 portion of this trial in August 2019 and preliminary data from the Phase 1 portion will be presented at the SITC annual meeting in November 2019. We began enrolling patients in the Phase 2 portion of the trial in October 2019 and expect to announce initial data from the Phase 2 portion by the end of 2020. In addition, we may develop a complementary diagnostic for NC318 if we determine it is advisable. We have exclusive worldwide rights to NC318.

        S15 is a member of the sialic acid-binding immunoglobulin lectins, or Siglec, family, a distinct subgroup of the immunoglobulin superfamily of proteins. Siglecs are expressed on most white blood cells of the immune system, except for T cells. Siglecs recognize and bind to a sugar structure called sialic acid that coats proteins and fatty acids found on the surface of all mammalian cells. This binding can affect cell signaling on immune cells. Several Siglecs play key roles in helping immune cells distinguish between self and non-self and modulating immune responses. In 2015, Dr. Chen discovered the immunosuppressive properties of S15 using the TCAA. S15 is expressed on tumor cells and, importantly, on M2 macrophages, which are highly immunosuppressive in the TME.

        S15 molecules on M2 macrophages, as well as on tumors themselves, appear to interact with unidentified receptors on T cells and inhibit T cell proliferation and functions, leading to decreased anti-tumor immune response. It also appears that S15 interacts with myeloid cells to promote their survival and differentiation so that they contribute to the overall immunosuppressive tumor environment through production of cytokines, such as IL-6, IL-1b and TNF-a, that are tumor-promoting and immunosuppressive in the context of the TME. As shown in the figure below, the presence of S15 on either tumor cells or M2 macrophages can lead to an immunosuppressive TME, resulting in tumor growth.


S15 is Highly Immunosuppressive in the TME

GRAPHIC

        The mechanism of action of NC318 prevents immune suppression caused by S15 and promotes anti-tumor activity. As the figure below shows, by targeting M2 macrophages, S15-induced myeloid cells and S15-positive tumors, NC318 is engineered to decrease inflammatory cytokines associated with enhanced tumor growth, promote T cell proliferation and restore T cell function, which we believe will reduce and kill tumors.

NC318 is Designed to Block Immunosuppressive Activity Induced by S15

GRAPHIC

        In preclinical studies, we have observed that S15 is highly expressed on both tumor cells and M2 macrophages in the TME in multiple tumor types, including human lung cancer, ovarian cancer, breast cancer and melanoma. In contrast, S15 expression on normal tissues is minimal. Our analysis shows that S15 exhibits a distinct expression pattern on tumors and functions independently from the PD-L1 pathway. The left panel of the following figure illustrates the expression of S15 relative to PD-L1 among more than 200 NSCLC tumor samples across multiple microarrays. Three distinct populations are identified: S15-positive and PD-L1-negative tumors; PD-L1-positive and S15-negative tumors; and tumors that express neither S15 nor PD-L1. This observation suggests that the expression of S15 is generally non-overlapping from PD-L1 on tumors. As reflected in the right panel of the following figure, we believe NC318 may provide a therapeutic solution for patients who have S15-positive and PD-L1-negative tumors, a patient population that is less likely to respond to a PD-1/PD-L1 directed therapy. This is consistent with our goal to develop immunomedicines that restore normal immune function in ways that differ from existing immunotherapies in order to provide effective therapies for patients who are not adequately served by currently available therapies.

        We believe S15 represents a novel target for the treatment of cancer. We and others have conducted multiple preclinical studies in various animal models evaluating the effect of inhibiting S15 by knocking out the gene responsible for producing S15 in mice. Across these studies, we observed that mice in which S15 is absent have generally developed normally, suggesting that the inhibition of S15 is not associated with adverse effects on normal cells. In subsequent studies, we observed that S15 knockout mice mounted enhanced antigen-specific T cell responses in vivo as compared with wild-type mice, as shown in the following figure. In addition, when S15 was knocked out in myeloid-derived cells, reflected as conditional knockout in the figure below, the mice mounted an enhanced antigen-specific T cell response similar to that of the knockout mice, which suggests the key role that macrophages play in S15-mediated immunosuppression. The data show a statistically significant increase in antigen-specific T cells in knockout and conditional knockout mice as compared to wild-type mice, and the increase is prolonged and maintained over a longer period than in the wild-type mice. In addition, we observed a significant increase in antigen-specific T cells in the spleen, as measured by the percentage of OVA+ CD8+ cells among CD8+ cells. The knockout mice showed an increase of nearly 20% as compared to less than 2% in wild-type mice. This suggests that S15 plays a key role in mediating immune suppression and the absence or inhibition of S15 could restore normal immune function.

The p-value, or probability value, cited in figures in this prospectus as "p," is the likelihood that an observed result occurred by chance. The smaller the p-value, the less likely that chance caused the result. A result that is sufficiently unlikely to have occurred by chance is referred to as being statistically significant. The FDA generally considers a p-value of less than or equal to 0.05, meaning that there is a 5% or less chance that the results occurred by chance, to be statistically significant.

        We also evaluated tumor progression in S15 knockout mice compared to wild-type mice in a glioma tumor model. As shown in the figures below, the knockout group showed delayed tumor progression as well as a corresponding increase in survival as compared to the wild-type group.

        In order to study the potential benefit of S15 inhibition in non-responders to PD-1/PD-L1 therapies, we conducted a preclinical study evaluating S15 knockout mice in a frequently used melanoma model, the B16.GMCSF tumor model, which has been demonstrated to be resistant to PD-1/PD-L1 therapy. We observed that S15 knockout mice demonstrated greater anti-tumor effect and, as shown in the following figure, had better overall survival than wild-type mice. We believe that this study suggests NC318 may have therapeutic potential in patients who do not respond to checkpoint inhibitors.

Knocking Out S15 Prolonged Survival in PD-1/PD-L1 Resistant Tumor Model

GRAPHIC

        In October 2018, we initiated a Phase 1/2 clinical trial to evaluate NC318 as a monotherapy in patients with advanced or metastatic solid tumors. This ongoing first-in-human trial is an open-label Phase 1/2 clinical trial designed to assess the safety and tolerability of NC318, to define the maximum tolerable dose and/or pharmacologically active dose and to assess preliminary efficacy. Patients receive NC318 on day one of each cycle. We initiated the trial with 14-day cycles; however, we may explore alternate doses and dose administration schedules depending on pharmacokinetics, pharmacodynamics, biomarker data, safety results and feedback from investigators. The trial is being conducted in two phases.

        The Phase 1 portion was designed to determine the pharmacologically active dose, defined as the dose that provides a maximal biologic effect, such as an increase in biomarkers of immune activation or a reduction of biomarkers associated with immune suppression, and/or the maximum tolerable dose of NC318, including defining the optimal dose administration schedule and the maximum number of tolerated doses. We completed enrollment of the Phase 1 portion of the trial in August 2019 and preliminary data from the Phase 1 portion will be presented in November 2019 at the SITC annual meeting.

        We began enrolling patients in the Phase 2 portion of the Phase 1/2 clinical trial of NC318 in October 2019. The Phase 2 portion of the trial is an open-label trial designed to detect a relevant efficacy signal, or response rate, for each tumor type at a 400 mg dose administered every two weeks. In this portion, we will enroll up to 100 patients with tumor types that have been shown to have elevated S15 expression, including NSCLC, ovarian cancer, HNSCC and TNBC. The primary endpoints for the Phase 2 portion of the trial are safety and tolerability, and secondary endpoints include response rate, progression-free survival, duration of response and overall survival. We expect to announce initial data from this portion of the trial by the end of 2020.

        We designed the clinical trial for NC318 with a robust biomarker strategy to help evaluate clinical activity throughout the trial by focusing on markers of pharmacodynamics. During the trial, we are obtaining a series of blood samples from patients before and during treatment. These blood samples are being used for the analysis and characterization of the immune cell population. T cell receptor clones are also being analyzed to detect evidence of therapy-induced clonal expansion of a subpopulation of antigen-specific T cells. Other assays relevant to the objectives of the trial, such as flow cytometry analysis of intracellular cytokines, may be performed based upon emerging data. In the Phase 2 portion of this trial, we will also obtain tumor biopsy samples before the first dose of NC318 and at least once more after the third dose. The biopsy samples will be used to investigate molecular signatures associated with response or resistance to treatment with NC318. We may also examine tissue by histology and immunohistochemistry or by exploratory methods to evaluate markers of inflammation and effector T cell populations, growth, signaling, apoptosis and similar markers that may be associated with safety, response or resistance to treatment with NC318. We believe our biomarker strategy will allow us to better monitor the clinical trial and could help shape the treatment strategy of NC318 in future clinical trials and, if approved, in clinical practice.

        In 2020, we intend to initiate a Phase 1/2 clinical trial to evaluate NC318 in combination with standard of care chemotherapies in patients with advanced or metastatic solid tumors. This trial will be an open-label trial conducted in two phases. The Phase 1 component will be designed to assess the safety and tolerability of NC318 in combination with at least two different chemotherapy regimens and to define the maximum tolerable dose of NC318 when administered with each chemotherapy. The Phase 2 component will be designed to assess preliminary efficacy of each combination in specific tumor types in a manner that can potentially support the use of such combinations in first-line therapies of advanced or metastatic solid tumors.

        Most syngeneic mouse tumor cell lines, which are common mouse models used to test immunotherapies, do not express S15. In order to study the effects of our S15-targeted antibody, we generated a tumor model where the mouse expresses S15. The model was initiated by differentiating mouse bone marrow cells into S15-positive M2 macrophages in vitro. These cells were then implanted into mice with an S15-negative mouse colon cancer cell line called CT26. The mice were then treated with either the S15-targeted antibody 5G12, the murine parent antibody of NC318, which has similar overall functional properties to NC318, or a control antibody. Across multiple preclinical studies, we evaluated the safety and efficacy of 5G12 and observed that blocking the effects of S15 with 5G12 restored immune function and anti-tumor immunity. For example, as the figure below shows, mice treated with 5G12 every four days for seven doses had smaller tumors and increased survival when compared to the mice treated with a control antibody.

        We also generated murine tumors expressing S15 on their surface. In our preclinical studies of an S15-positive murine colon cancer cell line, we observed that 5G12 delayed tumor growth and tumor metastasis, which was demonstrated by fewer lung nodules measured 28 days after treatment in the mice treated with 5G12 as compared to the mice treated with a control antibody, as shown in the figure below.


Treatment with 5G12 Delayed Tumor Metastasis in Lung Model

        Based on in vitro studies, we understand that S15 drives an increase in pro-inflammatory and pro-tumorigenic cytokines, such as IL-1b, IL-6 and TNF-a. As indicated in the figure below, when human peripheral blood mononuclear cells, or PBMCs, which are blood cells that are critical components in the immune system, were cultured in the presence of S15, the amount of pro-inflammatory and pro-tumorigenic cytokines increased, indicating an immunosuppressive environment. However, when human PBMCs were cultured with S15 protein and 5G12 or NC318, the amount of pro-inflammatory and pro-tumorigenic cytokines was reduced relative to when cultured with S15 and a control antibody. In addition, 5G12 and NC318 promoted the ability of human T cells to proliferate and produce interferon-gamma, or IFN-g. These data, which are shown in the figures below, suggest that 5G12 and NC318 have the potential to block immune suppression mediated by S15.

NC410

        NC410 is a fusion protein of LAIR-2, a naturally occurring soluble version of and decoy protein for LAIR-1, and is designed to block immune suppression mediated by LAIR-1. Multiple preclinical studies support our understanding that eliminating or blocking the binding of LAIR-1 restores normal immune function in multiple immune cells. Our translational work has shown that NC410 blocks the interaction of LAIR-1 with its binding partners, thereby promoting T cell function and dendritic cell activity to contribute to restoring anti-tumor immune activity. Consistent with our strategy, we believe NC410 has the potential to address the needs of patients who are not adequately addressed by currently available therapies. We are currently conducting IND-enabling studies and expect to file an IND and initiate a Phase 1/2 clinical trial in patients with advanced or metastatic solid tumors in the first quarter of 2020. We have exclusive worldwide rights to NC410.

        LAIR-1 is a co-inhibitory receptor expressed on T cells and several other immune cell subsets, including monocytes, macrophages and dendritic cells. Its binding partners include certain types of collagen and complement component 1q, or C1q.

        Under normal conditions, collagen forms a scaffold to provide strength and structure to tissues. C1q is part of the innate immune system to protect the host from infection and other foreign agents. Both collagen and C1q are highly upregulated and expressed under pathologic conditions, such as in the TME and in the immune organelles close to the tumor site known as lymph nodes, which are important sites for mounting immune responses to the tumor. However, binding of LAIR-1 to collagen or C1q leads to immune suppression. Our preclinical studies have shown that LAIR-1 and LAIR-2 bind to similar ligands, including collagen and C1q. LAIR-2, which is a secreted protein as opposed to a membrane-bound protein like LAIR-1, binds to the same regions of these ligands with stronger affinity than LAIR-1. However, because LAIR-2 does not induce immune suppression when binding to these ligands, LAIR-2 functions as an efficient decoy for LAIR-1.

        Under the harsh conditions of the TME, collagen and C1q are overexpressed as a membrane protein on many types of tumor cells and in the ECM surrounding the tumor. This increased expression of collagen and C1q, combined with insufficient levels of natural LAIR-2, leads to increased binding of LAIR-1, resulting in immune suppression, tumor immune evasion and tumor growth.

        NC410 is a novel immunotherapeutic protein that was developed to block LAIR-1-mediated immune suppression by mimicking the natural decoy effects of LAIR-2. Our approach of using NC410 as a

therapeutic is intended to take advantage of the natural LAIR-2 regulatory system in humans, which maintains human immune function under normal non-pathologic conditions.

        The mechanism of action of NC410 prevents immune suppression caused by LAIR-1 binding to collagen or C1q and promotes anti-tumor immune activity. As the figure below shows, when LAIR-2 and NC410 are present in the TME, they bind to collagen or C1q preferentially compared to LAIR-1 given their higher binding affinity. This has the effect of blocking the collagen or C1q from binding to LAIR-1, which otherwise would have resulted in an immunosuppressive effect. By blocking this interaction with LAIR-1 and its binding partners, T cell function and dendritic cell activity is promoted in order to restore anti-tumor immune activity.


NC410 is Designed to Prevent Immune Suppression Caused by LAIR-1

GRAPHIC

        We have conducted multiple preclinical studies to assess the activity of NC410 across a variety of preclinical models. These studies support our understanding that eliminating or blocking the binding of LAIR-1 to collagen or C1q can restore normal immune function in multiple immune cells, including T cells and myeloid cells, resulting in activation of T cells and anti-tumor immunity.

        We have observed in vitro with human cells that using NC410 to block LAIR-1 from binding with collagen or C1q reverses immune suppression and restores normal immune cell function for both peripheral blood monocytes, including T cells, and myeloid cells. In one study of peripheral blood monocytes, we added 0 µg/mL, 10 µg/mL and 100 µg/mL of NC410 to 20 µg/mL of collagen peptide in vitro. Similarly, we also evaluated the addition of 0 µg/mL, 2.5 µg/mL and 10 µg/mL of NC410 to 10 µg/mL of C1q on human myeloid cells. As shown in the figures below, NC410 promoted the activation of immune cells in the presence of high levels of collagen in peripheral blood monocytes and high levels of C1q in myeloid cells in a dose-dependent manner.

        In another preclinical study with human cells, we observed that NC410 promoted increases in the cytokines IL-2 and TNF-a, as shown in the left-hand panel of the following figure, which is indicative of increased immune function. In addition, simultaneous in vivo injections of NC410 and human T cells in immune-deficient mice resulted in increased amounts of CD4+ and CD8+ T cells, as shown in the right-hand panel of the figure below.

GRAPHIC

        Through multiple preclinical studies in several additional tumor models, we observed that eliminating or blocking LAIR-1-mediated immune suppression prolonged survival. In addition, anti-tumor activity of NC410 correlated with a local increase in antigen-specific T cells in the TME in vivo using an engineered mouse model to measure localized antigen-specific responses. We used an antigen-specific tumor model of EL4, a murine lymphoma cell line. We measured the weight of the animals daily as a proxy for tumor growth. As shown in the figure below, we observed that mice treated with NC410 had smaller tumors than mice treated with a control, suggesting that NC410 has potential anti-tumor activity.

NC410 Showed Anti-Tumor Activity

        We also measured T cells specific for ovalbumin, and as shown in the figures below, we observed systemic and local increases, as measured in the spleen and lymph node, respectively, in mice treated with NC410 compared to those treated with control. We believe that these data support an immune response in and around the TME.


NC410 Increased T Cells Both Systemically and Locally

GRAPHIC

        In addition, when human PBMCs were implanted into mice with mouse P815 mastocytoma tumor cells, we observed that NC410 mediated an increase in human T cells in vivo and that the increase in human T cells correlated with a delay in tumor growth. As shown in the figures below, NC410 increased the number of CD8+ T cells on day 13 in a dose-dependent manner and that increase corresponded to a decrease in tumor volume. To mimic human cancers, human PBMCs were also implanted into mice with human HT29 colon adenocarcinoma cells to test efficacy in a human tumor model. NC410 promoted an anti-tumor response against the human HT29 tumor cell line in a dose-dependent manner, as shown in the figure below.

        We and others have analyzed genomic and protein databases and observed that LAIR-1 expression levels negatively correlate with survival rates for several cancers, including brain, renal, colorectal, glioma, lung, urothelial and ovarian cancers. These analyses support possible targeting of these tumor types as primary indications for therapeutic treatment with NC410. We are conducting expansive screening efforts on tumor samples from different solid tumor types to identify tumors that express LAIR-1 on the surface of either cancer cells or infiltrating immune cells to guide our ultimate selection of patients for planned clinical trials of NC410 in humans.

        We are currently conducting IND-enabling studies for NC410 and plan to file an IND and initiate a Phase 1/2 clinical trial in patients with advanced or metastatic solid tumors in the first quarter of 2020.

Our Research Programs

        In addition to NC318 and NC410, we are also pursuing preclinical evaluation of other potential novel immunomodulatory molecules. Among these is an antibody that targets a novel member of the B7-family

of immunomodulatory proteins. In our preclinical studies, this antibody has shown highly reproducible and potent anti-tumor activity with in vivo modeling and appears to involve an important immunomodulatory pathway in the TME that may complement the activity of NC318 and NC410. Consistent with our focus on patients who do not respond to current therapies, patients whose cancer progresses despite treatment and patients with cancer types that are not adequately addressed by currently available therapies, the target of this antibody appears to be non-overlapping with the expression of both S15 and PD-L1 on tumor cells.

        We also have an antibody in preclinical development targeting an immune modulator that is highly expressed in inflamed tissue and the TME in multiple tumor types. In our preclinical research, we observed that disrupting inhibitory signaling by this molecule with our antibody increased T cell and NK cell effector functions.

        Based on our understanding of the LAIR pathway, including through our development of NC410, we are also pursuing monoclonal antibodies that target LAIR-1 and directly block LAIR-1 binding and signaling to prevent tumor growth or to eliminate the tumor. These novel LAIR-1 antibodies have unique functional properties that may provide additional opportunities in both cancer and autoimmune disorders.

Our FIND-IO Discovery Engine

        Our FIND-IO platform uses proprietary approaches to functionally assess immune pathways in both primary immune cells and established cell lines from immune lineages, including T cell subsets, monocytes, macrophage subpopulations, dendritic cells, cancer cell lines, and cells isolated from diseased patients. This platform allows us to identify proteins that can be targeted with novel immunomedicines to repair and maintain anti-tumor immunity. We have identified multiple novel targets using our FIND-IO platform, including those for which certain of our research programs are being designed to target.

        There are three integrated components to our FIND-IO platform. The first component consists of gene libraries, also called target libraries, comprising genes that are expressed and queried for immune or other functions. Our target libraries are composed of genes that encode a structurally diverse set of protein molecules and that are either inserted into the plasma membrane on the host cell surface or secreted outside of the host cell. The second component encompasses a variety of immune and non-immune cell types, called responder cells, used to evaluate the functional effects of the target libraries. The immune responder cell types include primarily immune cells obtained from human volunteers and multiple immune cell lines that have been grown in culture, and the non-immune responder cell types include tumor cell lines. The third component utilizes a broad set of outputs indicative of whether a newly discovered target inhibits or stimulates functional immune responses. We utilize a cube to illustrate these three components as shown in the figure below.

        Unlike other screening platforms that often focus on a single parameter or cell type, our approach uses a broad search across multiple cell types and multiple functions and is purposefully designed to produce physiologically relevant results. Although the orchestration of an immune response is complex and dynamic within the TME, we have designed the FIND-IO platform to be simple yet functional. The platform integrates multiple components to assess immune function resulting from cellular interactions in order to identify new immune modulators in an approach that mimics physiological interactions. The goal is to identify proteins that can be targeted with immunomedicines, such as monoclonal antibodies or fusion proteins. Potential targets that are preliminarily identified through the FIND-IO platform undergo reproducible, robust, relevant and comprehensive characterization resulting in functional readouts that improve the likelihood of developing immunomedicines against novel immune modulatory molecules. This approach is intended to meet our goal of extending beyond the success of current immunotherapies to treat patients who are not adequately addressed by currently available therapies and to enhance overall survival in these patients.

        The first step in the application of our FIND-IO platform is to transfect the target library into a host cell on a gene-by-gene basis. The host cells then express the library genes and the proteins are present on the cell surface or secreted into the surrounding space. In addition, the host cell has been engineered to express a reporter of transcriptional activity associated with a cellular function. For example, we engineer the host cells to report transcription factor activity in a cellular pathway by linking a selected DNA with a different fluorescent reporter, such as red fluorescent protein, or RFP. Thus, if the library gene expresses a protein that can signal via the applicable pathway, then the RFP gene is transcribed, expressed as a protein and the cell will glow red. The immune or non-immune responder cells are also engineered to express a reporter of transcriptional activity associated with a cellular function. For example, we engineer the responder cells to report transcription factor activity in a cellular pathway by linking a selected DNA with a fluorescent reporter such as green fluorescent protein, or GFP. Therefore, when transcription occurs in the responder cell, the GFP gene is transcribed, expressed as a protein and the cell will glow green. The red and/or green glow of the cells can be measured quantitatively. This is called bi-directional signaling as the

FIND-IO platform was designed to look at signaling events in the host cells as well as the immune and non-immune responder cells.

GRAPHIC

        The FIND-IO platform allows us to select and screen multiple immune and non-immune responder cell types, including T cells, myeloid cells, leukemia cells, epithelial cancer cells, plasma B cells and multiple myeloma cells, as well as primary immune cells from healthy donors. For each of these cell types, we undertake functional screening, including activity of many reporter pathways, effector function activity and effects on cell death, in order to identify novel immunomodulatory targets with common or differentiating effects across multiple cell types.

        Additionally, with our FIND-IO technology we can test for combination screens to search for synergistic or additive combinations with certain pathways, including immune checkpoint pathways, like the PD-1/PD-L1 pathway, that are currently approved for treating cancer patients. We expect that this screening will help with the identification of potential combination treatments to enhance response rates.

        The goal of our FIND-IO platform is to sustain a pipeline of novel immunomedicines that restore normal immune function to treat cancer and other immune-related diseases. While we are primarily focused on cancer treatment, we believe that our proprietary technology, our approach, our understanding of biological pathways and the convergence of immunology and inflammation provide us with opportunity to explore novel immunomedicines for other significant unmet medical needs. To maximize the full potential of our platform and expertise, we are expanding the functional screening approach of our FIND-IO platform to the identification of novel targets in autoimmunity and inflammation, where we are using this approach to develop our FIND-AI platform, as well as in neuro-inflammatory diseases.

Our Collaboration Agreements

Agreements with Yale University

        In December 2015, we entered into a license agreement with Yale, or the Yale Agreement, pursuant to which we obtained an exclusive, royalty-bearing, sublicensable worldwide license to products that either

109


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

incorporate certain licensed patents used in the discovery of targets or arise out of research and development of Dr. Chen's laboratory at Yale, including S15. We are obligated to pay Yale low single-digit royalties on sales of products, including NC318, that are either covered by the patents licensed to us under the Yale Agreement or arise out of Dr. Chen's laboratory, subject to minimum annual royalty payments in the low to mid hundreds of thousands of dollars. Until we are required to pay royalties under the Yale Agreement, we must pay an annual license maintenance fee to Yale in the mid to high tens of thousands of dollars. In addition, with respect to each product covered by licenses under the Yale Agreement, we are obligated to pay Yale milestone payments upon (i) the initiation of each of a Phase 1 clinical trial, Phase 2 clinical trial and Phase 3 clinical trial or a pivotal trial, (ii) first commercial sale in the United States and (iii) first commercial sale in China, Japan or a major European country, in an aggregate amount of up to $2,975,000. The term of the license agreement with Yale runs, on a country-by-country basis, until the later of the expiration of all licensed patents or 10 years from the first commercial sale in such country, unless Yale has cause to terminate earlier for our material breach of the license, bankruptcy or if we or any sublicensee bring a challenge against Yale in relation to the licensed patents. We have the right to terminate the Yale Agreement for Yale's material breach or at any time during the term with six months' prior written notice to Yale.

        In connection with the Yale Agreement, we also entered into a corporate sponsored research agreement, or SRA, with Yale, in which we agreed to provide an aggregate of up to $12.4 million to fund a research program aimed at discovering new targets for immunomedicines. The research program is under the direction and supervision of Dr. Chen. Pursuant to the SRA, we have the option to add any patents invented pursuant to the research program as a licensed patent under the Yale Agreement and the right to obtain a royalty-bearing, exclusive, worldwide license to any such patents. If we do not exercise our option within the exercise period, Yale is permitted to license any such patents to any third party. The SRA will expire on December 31, 2020, and we have the option of extending the term upon mutual agreement with Yale. We can terminate the SRA at any time upon 90 days' written notice to Yale. Yale can terminate for an uncured breach or with 90 days' written notice for cause.

Research and Development Collaboration with Lilly

        In November 2018, we entered into the Lilly Agreement, pursuant to which we will use our FIND-IO platform to identify novel oncology targets for additional collaborative research and drug discovery by us and Lilly. Under this agreement, we granted Lilly the exclusive option to obtain worldwide exclusive licenses to research, develop, manufacture and commercialize multiple compounds and products directed to oncology targets identified through our research collaboration. Lilly currently has all options remaining eligible for exercise. In addition, Lilly granted us the exclusive option to obtain worldwide exclusive licenses to research, develop, manufacture and commercialize an equal number of compounds and products directed to oncology targets for which Lilly does not exercise its option. We currently have all options remaining eligible for exercise. Under the Lilly Agreement, we retain all rights to our intellectual property outside of oncology for any targets that are not actively being researched and developed pursuant to the Lilly Agreement.

        Under the Lilly Agreement, we and Lilly have agreed to engage in a multi-year research collaboration, which will be managed by a joint steering committee formed by an equal number of members from each party and expire upon the earlier of the exercise of all options granted to Lilly or four years from the date of the agreement, subject to certain extensions. We have granted Lilly exclusivity with respect to targets identified through our FIND-IO platform that can be used in the oncology field during the research term or until Lilly has exercised all of its options.

        During the research term, as a part of target discovery, we will be responsible for providing Lilly with oncology targets identified using our FIND-IO platform. From the targets provided by us, Lilly may select

110


Table of Contents

targets to advance to target validation using criteria developed by both parties. Following completion of the agreed upon target validation plan with respect to a given target, either party may propose to advance that target to compound discovery. For each target that has been advanced to compound discovery, Lilly will have the option to obtain an exclusive license in all fields of use with respect to the compounds and products directed to the target. If Lilly does not exercise its option with respect to a given target that has advanced through compound discovery, or has previously exercised all of its options, we have the option to obtain licenses with respect to compounds and products directed to the target. Lilly and we may each exercise our respective options with respect to targets during the research term. Following option exercise by a party, the development and commercialization of any compounds and products directed to the target will be conducted by the exercising party. The exercising party must use commercially reasonable efforts to develop, seek regulatory approval for and commercialize any such products under mutually agreed work plans.

        We received an upfront, non-refundable payment of $25.0 million in cash and a $15.0 million equity investment from Lilly upon entering into the agreement. Lilly is also required to pay us quarterly research and development support payments in an aggregate in the mid single digit millions of dollars during a portion of the research term as well as option exercise fees in an aggregate of up to the high single digit millions of dollars upon the exercise of options by Lilly. For the first product directed to each target optioned by Lilly, Lilly will pay development and regulatory milestones. For the first additional indication in a different therapeutic area for such product, Lilly will pay regulatory milestones upon regulatory approval in each of the United States, European Union and Japan. Additionally, regardless of indication, Lilly will pay sales milestones as well as mid to high single-digit royalties on net sales for all products directed to each target optioned by Lilly. The milestone payments could amount to an aggregate of up to $1.4 billion. This amount assumes that Lilly exercises all of the options available to it, as well as the successful achievement of all development and regulatory milestones and sales milestones for each target optioned by Lilly.

        Upon our exercise of an option with respect to a given target, we will owe Lilly option exercise, milestone and royalty payments in amounts equivalent to a portion of the amounts payable by Lilly were Lilly to exercise an option, including an aggregate of up to $710 million in development and regulatory milestones and sales milestones and low to mid single-digit royalties. Unless terminated earlier, the term of the Lilly Agreement will continue in effect, on a product-by-product and country-by-country basis, until the expiration of the applicable royalty term. Either party may terminate the agreement, in whole or in part, for the other's material breach that has not been cured within a certain period or general assignment for the benefit of creditors or in connection with the other's bankruptcy or insolvency. In addition, Lilly has the right to terminate the agreement in its entirety or with respect to one or more specified products or targets at any time with 60 days prior notice. To the extent that we terminate for Lilly's material breach or insolvency or Lilly terminates for convenience, all licenses and rights granted by us to Lilly will automatically terminate and the licenses and rights granted by Lilly to us will survive. Similarly, if Lilly terminates for our material breach or insolvency, all licenses and rights granted by Lilly to us will automatically terminate, and the licenses and rights granted by us to Lilly will survive. In such cases, all future royalties and milestones will be reduced in an amount to be reasonably agreed by the parties.

Manufacturing

        We have a purpose-built, dedicated, state-of-the-art cGMP manufacturing facility that utilizes single-use technology to support our pipeline and advance our product candidates into and through clinical development. The facility has an initial production capacity of 1,000 liters and was designed with additional room for expansion to support multiple product candidates. The investment in our manufacturing facility is a critical element of our ability to quickly identify whether a candidate is likely to be successful and to facilitate an efficient development path. While other companies may need to work with third parties for antibody production, we can do so in our own facility. Compared to working with third-party

111


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

manufacturers, we believe our facility provides better quality assurance, greater control in scheduling and prioritizing manufacturing activities and enhanced capital efficiency. We are currently manufacturing all of the drug supply for our preclinical studies and our Phase 1/2 clinical trial of NC318 and intend to expand our cGMP manufacturing capacity, including to provide the drug supply for future clinical trials of NC318. As we advance the development of our growing pipeline of product candidates, we will continue to evaluate the merits of further expanding our internal manufacturing capabilities, including for the production of commercial drug supply, as compared to collaborating with third-party manufacturers.

Competition

        The biotechnology and pharmaceutical industries, and the immuno-oncology subsector, are characterized by rapid evolution of technologies, fierce competition and strong defense of intellectual property. We believe that our programs, platforms, technology, knowledge, experience and scientific resources provide us with competitive advantages, but we also face competition from pharmaceutical and biotechnology companies, academic institutions, governmental agencies and public and private research institutions, among others. Our competitors include larger and better funded biopharmaceutical, biotechnology and therapeutics companies, including companies focused on cancer immunotherapies, such as Amgen, Inc., AstraZeneca plc, Bristol-Myers Squibb Company, or BMS, Genentech, Inc., GlaxoSmithKline PLC, Merck & Co., Inc., Novartis AG, Pfizer Inc., Roche Holding Ltd and Sanofi S.A. Moreover, we may also compete with smaller or earlier-stage companies, universities and other research institutions that have developed, are developing or may be developing current and future cancer therapeutics.

        Product candidates that we successfully develop and commercialize will compete with a range of therapies that are currently approved and any new therapies that may become available in the future. Key product features that would affect our ability to effectively compete with other therapeutics include the efficacy, safety and convenience of our products. Currently marketed oncology drugs and therapeutics range from traditional cancer therapies, including chemotherapy, to antibody-drug conjugates, such as Genentech Inc.'s Kadcyla, to immune checkpoint inhibitors targeting CTLA-4, such as BMS' Yervoy, and PD-1/PD-L1, such as BMS' Opdivo, Merck & Co.'s Keytruda and Genentech's Tecentriq, to T cell-engager immunotherapies, such as Amgen's Blincyto. In addition to these marketed therapies, numerous compounds are in clinical development for the potential treatment of cancer.

        The availability of reimbursement from government and other third-party payors will also significantly affect the pricing and competitiveness of our products. Our competitors may also obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market.

Intellectual Property

        Our commercial success depends in part on our ability to obtain and maintain proprietary protection for our products, methods and manufacturing processes, to operate without infringing the proprietary rights of others and to prevent others from infringing our proprietary rights. We rely on a combination of patent applications and trade secrets, as well as contractual protections, to establish and protect our intellectual property rights. We seek to protect our proprietary position by, among other things, filing patent applications in the United States and internationally. Our patent estate includes patent applications with claims relating to our product candidates, methods of use and manufacturing processes, and claims for potential future products and developments. As of October 29, 2019, our intellectual property portfolio includes, on a worldwide basis, 18 pending foreign patent applications relating to NC318 and NC410, one pending U.S. patent application relating to NC318, one pending U.S. patent application relating to NC410 and additional pending patent applications for other discovery and research programs. Patents resulting from our patent applications for NC318 and NC410, if issued, are expected to expire beginning in 2037 absent any patent term adjustments or extensions.

112


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

        In addition, as described above, under the Yale Agreement, we have an exclusive, royalty-bearing, sublicensable worldwide license from Yale for an intellectual property portfolio, including patent applications, relating to methods of use for S15 that covers the use of NC318. Any patents from these patent applications, if issued, are expected to expire no earlier than 2036 absent any patent term adjustments or extensions.

        For all patent applications, we determine strategy for claim scope on a case-by-case basis, taking into account advice of counsel and our business model and needs. We file patents containing claims for protection of all useful applications of our proprietary technologies and any products, as well as all new applications and/or uses we discover for existing technologies and products, based on our assessment of their strategic value. We continuously reassess the number and type of patent applications, as well as the pending and issued patent claims to ensure that maximum coverage and value are obtained for our processes and compositions, given existing patent office rules and regulations. Further, claims may be modified during patent prosecution to meet our intellectual property and business needs.

        We also rely upon trade secrets, know-how and continuing technological innovation to develop and maintain our competitive position, including with respect to our FIND-IO platform. We seek to protect our proprietary technology and processes, in part, by confidentiality and invention assignment agreements with our employees, consultants, scientific advisors and other contractors. In addition, in the ordinary course of our business, we enter into agreements with other third parties for non-exclusive rights to intellectual property directed to other technologies that are ancillary to our business, including laboratory information management software and research and development tools. In addition, we have filed for trademark registration with the U.S. Patent and Trademark Office, or the USPTO, for "NextCure," our logo and our FIND-IO platform.

Government Regulation

Government Regulation and Product Approval

        The FDA and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, recordkeeping, approval, advertising, promotion, marketing, post-approval monitoring and post-approval reporting of biological products. Along with third-party contractors, we will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates. The processes for obtaining regulatory approvals in the United States and in foreign jurisdictions, along with subsequent compliance with applicable laws and regulations and other regulatory authorities, require the expenditure of substantial time and financial resources.

        Government policies may change and additional government regulations may be enacted that could prevent or delay further development or regulatory approval of any product candidates, product or manufacturing changes, additional disease indications, or label changes. We cannot predict the likelihood, nature or extent of government regulation that might arise from future legislative or administrative action.

Review and Approval for Licensing Biologics in the United States

        In the United States, the FDA regulates our current product candidates as biological products, or biologics, under the Federal Food, Drug, and Cosmetic Act, or FDCA, the Public Health Service Act and associated implementing regulations. Biologics, like other drugs, are used for the treatment, prevention or cure of disease in humans. In contrast to chemically synthesized small molecular weight drugs, which have a well-defined structure and can be thoroughly characterized, biologics are generally derived from living material (human, animal, or microorganism) are complex in structure, and thus are usually not fully characterized. Biologics include immunomedicines for cancer and other diseases.

113


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

        Biologics are also subject to other federal, state and local statutes and regulations. The failure to comply with applicable statutory and regulatory requirements at any time during the product development process, approval process or after approval may subject a sponsor or applicant to administrative or judicial enforcement actions. These actions could include the suspension or termination of clinical trials by the FDA, the FDA's refusal to approve pending applications or supplemental applications, withdrawal of an approval, Warning Letters or Untitled Letters, product recalls, product seizures, total or partial suspension of production or distribution, import detention, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by the FDA, the Department of Justice, or the DOJ, or other governmental entities.

        An applicant seeking approval to market and distribute a biologic in the United States must typically undertake the following:

        From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the testing, approval, manufacturing and marketing of products regulated by the FDA. In addition to new legislation, FDA regulations and policies are often revised or interpreted by the agency in ways that may significantly affect our business and our products. It is impossible to predict whether further legislative changes will be enacted or whether FDA regulations, guidance, policies or interpretations will be changed or what the effect of such changes, if any, may be.

Preclinical and Clinical Development

        Before an applicant can begin testing the potential candidate in human subjects, the applicant must first conduct preclinical studies. Preclinical studies include laboratory evaluations of product chemistry, toxicity and formulation, as well as in vitro and animal studies to assess the potential safety and activity of the drug for initial testing in humans and to establish a rationale for therapeutic use. Preclinical studies are subject to federal regulations and requirements, including GLP regulations. The results of an applicant's preclinical studies are submitted to the FDA as part of an IND.

        An IND is a request for authorization from the FDA to administer an investigational new drug product to humans. An IND is an exemption from the FDCA that allows an unapproved drug to be shipped in interstate commerce for use in an investigational clinical trial. Such authorization must be secured prior to interstate shipment and administration of a biologic that is not subject of an approved BLA. In support of a request for an IND, applicants must submit a protocol for each clinical trial. Any subsequent protocol amendments must be submitted to the FDA as part of the IND.

        Human clinical trials may not begin until an IND is effective. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA raises safety concerns or questions about the proposed clinical trial within the 30-day time period. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.

        The FDA may also place a clinical hold or partial clinical hold on such trial following commencement of a clinical trial under an IND. A clinical hold is an order issued by the FDA to the sponsor to delay a proposed clinical investigation or to suspend an ongoing investigation. A partial clinical hold is a delay or suspension of only part of the clinical work requested under the IND. For example, a specific protocol or part of a protocol is not allowed to proceed, while other protocols may do so. No more than 30 days after imposition of a clinical hold or partial clinical hold, the FDA will provide the sponsor a written explanation of the basis for the hold. Following issuance of a clinical hold or partial clinical hold, an investigation may only resume after the FDA has notified the sponsor that the investigation may proceed. The FDA will base that determination on information provided by the sponsor correcting the deficiencies previously cited or otherwise satisfying the FDA that the investigation can proceed.

        Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with cGCP regulations, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments.

        A sponsor may choose, but is not required, to conduct a foreign clinical study under an IND. When a foreign clinical study is conducted under an IND, all FDA IND requirements must be met unless waived. When the foreign clinical study is not conducted under an IND, the sponsor must ensure that the study complies with cGCP regulations in order to use the study as support for an IND or application for marketing approval, including cGCP regulations, including review and approval by an independent ethics committee and informed consent from subjects.

        Furthermore, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site, and must monitor the trial until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives.

115


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

        Some trials also include oversight by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board, or DSMB. DSMBs provide authorization for whether or not a trial may move forward at designated check points based on access to certain data from the trial and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. Other grounds for suspension or termination may be made based on evolving business objectives and/or competitive climate. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public registries.

Clinical Trials

        For purposes of BLA approval, clinical trials are typically conducted in the following sequential phases:

        These phases may overlap or be combined. In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more information about the product, referred to as Phase 4 trials. Such post-approval trials, when applicable, are conducted following initial approval, typically to develop additional data and information relating to the biological characteristics of the product and treatment of patients in the intended therapeutic indication.

        Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events occur. In addition, IND safety reports must be submitted to the FDA for any of the following: suspected serious and unexpected adverse reactions; findings from epidemiological studies, pooled analysis of multiple studies, animal or in vitro testing, or other clinical studies, whether or not conducted under an IND, and whether or not conducted by the sponsor, that suggest a significant risk in humans exposed to the drug; and any clinically important increase in the rate of a serious suspected adverse reaction over such rate listed in the protocol or investigator brochure.

        Our planned clinical trials may not be completed successfully within any specified period, or at all. Furthermore, the FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution, or an institution it represents, if the clinical trial is not being conducted in accordance with the IRB's requirements or if the drug has been associated with unexpected serious harm to patients. The FDA will typically inspect one or more clinical sites to assure compliance with cGCP and the integrity of the clinical data submitted.

        During clinical development, the sponsor often refines the indication and endpoints on which the BLA will be based. For endpoints based on patient-reported outcomes, or PROs, and outcome reported outcomes, or OROs, the process typically is an iterative one. The FDA has issued guidance on the framework it uses to evaluate PRO instruments. Although the agency may offer advice on optimizing PRO and ORO instruments during the clinical development process, the FDA usually reserves final judgment until it reviews the BLA.

        Concurrent with clinical trials, companies often complete additional animal studies, and develop additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things, must develop methods for testing the identity, strength, quality, purity and potency of the final drug. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life.

BLA Submission and Review

        Assuming successful completion of all required clinical testing in accordance with all applicable regulatory requirements, an applicant may submit a BLA requesting licensing to market the biologic for one or more indications in the United States. The BLA must include the results of product development, nonclinical studies and clinical trials; detailed information on the product's chemistry, manufacture, controls; and proposed labeling. Under the Prescription Drug User Fee Amendments, a BLA submission is subject to an application user fee, unless a waiver or exemption applies.

        The FDA will initially review the BLA for completeness before accepting it for filing. Under the FDA's procedures, the agency has 60 days from its receipt of a BLA to determine whether the application will be accepted for filing and substantive review. If the agency determines that the application does not meet this initial threshold standard, the FDA may refuse to file the application and request additional information, in which case the application must be resubmitted with the requested information and review of the application delayed.

        With certain exceptions, BLAs must include a pediatric assessment, generally based on clinical trial data, of the safety and effectiveness of the biologic in relevant pediatric populations. Under certain circumstances, the FDA may waive or defer the requirement for a pediatric assessment, either at the sponsor's request or by the agency's initiative.

        After the BLA is accepted for filing, the FDA reviews the BLA to determine, among other things, whether a product is safe, pure and potent and if the facility in which it is manufactured, processed, packed or held meets standards designed to assure the product's continued identity, strength, quality, safety, purity and potency. The FDA may convene an advisory committee to provide clinical insight on application review questions. Before approving a BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities comply with cGMP and are adequate to assure consistent production of the product within required specifications. In addition, the FDA expects that all data be reliable and accurate, and requires sponsors to implement meaningful and effective strategies to manage data integrity risks. Data integrity is an important component of the sponsor's responsibility to ensure the safety, efficacy and quality of its product or products.

        The FDA will typically inspect one or more clinical sites to assure compliance with cGCP regulations before approving a BLA. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

        FDA performance goals generally provide for action on a BLA within 10 months of filing, which (as discussed above) typically occurs within 60 days of submission, but that deadline is extended in certain circumstances. Furthermore, the review process is often significantly extended by FDA requests for additional information or clarification.

        The FDA may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee. Typically, an advisory committee consists of a panel that includes clinicians and other experts who will review, evaluate and provide a recommendation as to whether the application should be approved and, if so, under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions and usually has followed such recommendations.

        After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its components will be produced, the FDA may issue an approval letter or a Complete Response Letter, or CRL. An approval letter authorizes commercial marketing of the biologic with specific prescribing information for specific indications. A CRL will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the CRL without first conducting required inspections, testing submitted product lots and/or reviewing proposed labeling. If and when the deficiencies have been addressed to the FDA's satisfaction in a resubmission of the BLA, the FDA will issue an approval letter. In issuing the CRL, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional data, information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, and may require additional testing or information and/or require post-marketing studies and clinical trials. Even with submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

        During the approval process, the FDA will determine whether a REMS is necessary to assure the safe use of the biologic. A REMS is a safety strategy to manage a known or potential serious risk associated with a product and to enable patients to have continued access to such medicines by managing their safe use, and could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. If the FDA concludes that a REMS is needed, the BLA sponsor must submit a proposed REMS and the FDA will not approve the BLA without a REMS that the agency has determined is acceptable.

        If the FDA approves a product, it may limit the approved indications for use for the product, or require that contraindications, warnings or precautions be included in the product labeling. The FDA may also require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess the drug's safety after approval. The FDA may prevent or limit further marketing of a product based on the results of post-market studies or surveillance programs.

        The FDA may also require testing and surveillance programs to monitor the product after commercialization. For biologics, such testing may include official lot release, which requires the manufacturer to perform certain tests on each lot of the product before it is released for distribution. The manufacturer then typically must submit samples of each lot of product to the FDA, together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer's tests performed on the lot. The FDA may also perform certain confirmatory tests on lots of some products itself, before releasing the lots for distribution by the manufacturer.

        After approval, many types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are often subject to further testing requirements and FDA review and approval, depending on the nature of the post-approval change. The FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace.

Pediatric Studies

        Under the Pediatric Research Equity Act, a BLA or BLA supplement thereto must contain data that are adequate to assess the safety and effectiveness of the drug product for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. Those plans must contain an outline of the proposed pediatric study or studies the applicant plans to conduct, including study objectives and design, any deferral or waiver requests and any other information required by regulation. The applicant, the FDA and the FDA's internal review committee must then review the information submitted, consult with each other, and agree upon a final plan. The FDA or the applicant may request an amendment to the plan at any time. In addition, the FDA Reauthorization Act of 2017 requires the FDA to meet early in the development process to discuss pediatric study plans with drug sponsors. The law requires the FDA to meet with drug sponsors by no later than the end-of-Phase 1 meeting for serious or life-threatening diseases and by no later than 90 days after the FDA's receipt of the study plan.

        The FDA may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the product for use in adults, or full or partial waivers from the pediatric data requirements. For example, the requirement for such studies or clinical trials may be waived if necessary studies or clinical trials in children are impossible, there is strong evidence suggesting the drug will not be effective or safe in children, the drug does not represent a meaningful therapeutic benefit over existing therapies for children, or the drug is not likely to be used in a substantial number of children. Such studies or clinical trials may also be deferred if the drug is ready for approval in adults before pediatric studies or clinical trials are completed or due to concerns about the safety or effectiveness of the drugs in pediatric populations. When such studies or clinical trials are deferred, they will be reported as post-marketing requirements. Pediatric data requirements do not apply to products with orphan designation.

Post-Approval Requirements

        Any products manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, reporting of certain deviations and adverse experiences, product sampling and distribution and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to FDA review and approval. There also are continuing user fee requirements, under which FDA assesses an annual program fee for each product identified in an approved BLA. Biologic manufacturers and their third-party contractors are required to register their establishments with the FDA and certain state agencies. These establishments are subject to routine and periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and data integrity requirements, which impose certain procedural and documentation requirements to assure quality of manufacturing and product. FDA has increasingly observed cGMP violations involving data integrity during site inspections and is a significant focus of its oversight. Requirements with respect to data integrity include, among other things, controls to ensure data are complete and secure; activities documented at the time of performance; audit trail functionality; authorized access and limitations; validated computer systems; and review of records for accuracy, completeness and compliance with established standards.

        Post-approval changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP, data integrity, pharmacovigilance and other aspects of regulatory compliance.

        The FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-approval studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS. Other potential consequences include, among other things:

        The FDA strictly regulates the marketing, labeling, advertising and promotion of prescription drug products placed on the market. A company can make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. The FDA's regulation includes, among other things, standards and regulations for direct-to-consumer advertising, communications regarding unapproved uses, industry-sponsored scientific and educational activities and promotional activities involving the Internet and social media. Promotional claims relating to a product's safety or effectiveness are prohibited before the drug is approved. After approval, a product generally may not be promoted for uses that are not approved by the FDA, as reflected in the product's prescribing information. In the United States, healthcare professionals are generally permitted to prescribe drugs for such uses not described in the drug's labeling, known as off-label uses, because the FDA does not regulate the practice of medicine. However, FDA regulations impose rigorous restrictions on manufacturers' communications, prohibiting the promotion of off-label uses. It may be permissible, under very specific, narrow conditions, for a manufacturer to engage in non-promotional, non-misleading communication regarding off-label information, such as distributing scientific or medical journal information.

        If a company is found to have promoted off-label uses, it may become subject to adverse public relations and administrative and judicial enforcement by the FDA, the DOJ or the Office of the Inspector General of the Department of Health and Human Services, or HHS, as well as other federal and state authorities. This could subject a company to a range of penalties that could have a significant commercial impact, including civil and criminal fines and agreements that materially restrict the manner in which a company promotes or distributes products. The federal government has levied large civil and criminal fines against companies for alleged improper promotion, and has also requested that companies enter into consent decrees and permanent injunctions under which specified promotional conduct is changed or curtailed.

        The distribution of prescription drug and biologic are subject to the Drug Supply Chain Security Act, or DSCSA, which requires manufacturers and other stakeholders to comply with product identification, tracing, verification, detection and response, notification and licensing requirements. In addition, the Prescription Drug Marketing Act, or PDMA, and its implementing regulations, and state laws limit the distribution of prescription pharmaceutical product samples, and the DSCSA imposes requirements to ensure accountability in distribution and to identify and remove prescription drug and biological products that may be counterfeit, stolen, contaminated, or otherwise harmful from the market.

Patent Term Restoration and Marketing Exclusivity

        After approval, owners of relevant drug or biological product patents may apply for up to a five year patent extension to restore a portion of patent term lost during product development and FDA review of a BLA if approval of the application is the first permitted commercial marketing or use of a biologic containing the active ingredient under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act. The allowable patent term extension is calculated as one-half of the product's testing phase, which is the time between IND and BLA submission, and all of the review phase, which is the time between BLA submission and approval, up to a maximum of five years. The time can be shortened if the FDA determines that the applicant did not pursue approval with due diligence. The total patent term after the extension may not exceed more than 14 years from the date of FDA approval of the product. Only one patent claiming each approved product is eligible for restoration and the patent holder must apply for restoration within 60 days of approval. The USPTO, in consultation with the FDA, reviews and approves the application for patent term restoration.

        For patents that might expire during the application phase, the patent owner may request an interim patent extension. An interim patent extension increases the patent term by one year and may be renewed up to four times. For each interim patent extension granted, the post-approval patent extension is reduced by one year. The director of the USPTO must determine that approval of the product candidate covered by the patent for which a patent extension is being sought is likely. Interim patent extensions are not available for a product candidate for which a BLA has not been submitted.

Biosimilars and Marketing Exclusivities

        The Biologics Price Competition and Innovation Act, or BPCIA, created an abbreviated approval pathway for biological product candidates shown to be highly similar to or interchangeable with an FDA licensed reference biological product. Biosimilarity sufficient to reference a prior FDA-approved product requires that there be no differences in conditions of use, route of administration, dosage form and strength, and no clinically meaningful differences between the biological product candidate and the reference product in terms of safety, purity and potency. Biosimilarity must be shown through analytical trials, animal trials and at least one clinical trial, unless the Secretary of HHS waives a required element. A biosimilar product candidate may be deemed interchangeable with a prior approved product if it meets the higher hurdle of demonstrating that it can be expected to produce the same clinical results as the reference product and, for products administered multiple times, the biologic and the reference biologic may be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. To date, a handful of biosimilar products and no interchangeable products have been approved under the BPCIA. Complexities associated with the larger, and often more complex, structures of biologics, as well as the process by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by the FDA.

        A reference biologic is granted 12 years of exclusivity from the time of first licensure of the reference product, and no application for a biosimilar can be submitted for four years from the date of licensure of the reference product. The first biological product candidate submitted under the abbreviated approval pathway that is determined to be interchangeable with the reference product has exclusivity against a finding of interchangeability for other biologics for the same condition of use for the lesser of (i) one year after first commercial marketing of the first interchangeable biosimilar, (ii) 18 months after the first interchangeable biosimilar is approved if there is no patent challenge, (iii) 18 months after resolution of a lawsuit over the patents of the reference biologic in favor of the first interchangeable biosimilar applicant, or (iv) 42 months after the first interchangeable biosimilar's application has been approved if a patent lawsuit is ongoing within the 42 month period. At this time, it is unclear whether products deemed "interchangeable" by the FDA will, in fact, be readily substituted by pharmacies, which are governed by state pharmacy laws and regulations.

        If a biologic is designated and approved for an orphan indication, it will be granted seven years of orphan drug exclusivity. An orphan indication is granted to biological products and drugs designated and approved to treat diseases or conditions affecting fewer than 200,000 individuals in the United States, or if there is no reasonable expectation that the sponsor will be able to recover the costs of developing and marketing the drug or biological product in the United States. A biosimilar may not be licensed by FDA for the protected orphan indication until after the expiration of the seven year orphan drug exclusivity period or the 12 year reference product exclusivity, whichever is later.

        Pediatric exclusivity adds an additional six month exclusivity period to any marketing exclusivities and patents that a biological product has obtained. In order to obtain pediatric exclusivity, a BLA sponsor must conduct pediatric studies as requested by the FDA in a Written Request. The data do not need to show the product to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA's request, the additional protection is granted. If reports of requested pediatric studies are submitted to and accepted by the FDA within the statutory time limits, whatever statutory or regulatory periods of exclusivity or patent protection cover the product are extended by six months. While pediatric exclusivity is not an actual extension on a patent term, it effectively extends the preclusive effect of the patent on FDA's authority to approve another application that relies on the product with pediatric exclusivity.

        The BPCIA is complex and continues to be interpreted and implemented by the FDA. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars. In July 2018, the FDA released its Biosimilars Action Plan to improve the efficiency of the biosimilar and interchangeable product development and approval process. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation and impact of the BPCIA is subject to significant uncertainty.

Regulation of Companion Diagnostics and Laboratory Developed Tests

        A companion diagnostic is an in vitro diagnostic that can: identify the patients most likely to benefit from a particular therapeutic product; identify those likely to be at an increased risk for serious side effects; or monitor responses to treatment with a particular therapeutic product for the purpose of adjusting treatment to achieve improved safety or effectiveness. Under the FDCA, in vitro companion diagnostics are generally regulated as medical devices. The FDA has generally classified in vitro companion diagnostics as high-risk, Class III devices, which require FDA approval of a premarket approval application, or PMA, but recognizes the possibility of a moderate-risk IVD companion diagnostic (i.e., Class II device), which would require clearance of a 510(k) premarket notification or grant of a de novo request. Approval or clearance of the in vitro companion diagnostic device will ensure that the device has been adequately evaluated and has adequate performance characteristics in the intended population.

        For those in vitro companion diagnostics that require PMA approval, the process involves gathering and submitting clinical and preclinical data on the device for review by the FDA. It involves a rigorous premarket review, during which the applicant must provide the FDA with reasonable assurance of the device's safety and effectiveness, as well as information regarding the device's design, manufacturing and labeling. In addition, the FDA will typically inspect the device manufacturer's facilities for compliance with the Quality System Regulation, which imposes testing, control, documentation and other quality assurance requirements.

        The FDA has issued guidance on the approval of therapeutic products and in vitro companion diagnostic devices. According to the FDA's guidance, for novel therapeutic products including biologics, an in vitro companion diagnostic device and its corresponding therapeutic should be approved or cleared contemporaneously by the FDA for the use indicated in the therapeutic product's labeling.

        In some cases, information from a diagnostic test may be useful to a prescriber, but not necessary for the safe and effective administration of the therapeutic product. In those cases, health care providers may employ information derived from a laboratory developed test, or LDT, when administering a therapeutic product. An LDT is a type of in vitro diagnostic test that is designed, manufactured and used within a single laboratory. LDTs can be used to measure or detect a wide variety of analytes (substances such as proteins, chemical compounds like glucose or cholesterol, or DNA), in a sample taken from a human body.

        The Centers for Medicare and Medicaid Services, or CMS, regulates LDTs and the laboratories that develop them, and enforces the Clinical Laboratories Improvement Amendments, or CLIA. CMS evaluates whether there is clinical utility for each specific test, and also performs postmarket oversight of laboratory operational processes. CMS's oversight through the CLIA program is designed to confirm that a lab assesses analytical validity, but does not confirm whether it had results from an analytical validity assessment that were sufficient to support the claimed intended use of the test.

        Historically, the FDA has generally not enforced premarket review and other FDA requirements on LDTs because LDTs were relatively simple lab tests and generally available on a limited basis. Due to advances in technology, however, some LDTs are now much more complex, have a nationwide reach and present higher risks, such as detection of risk for breast cancer and Alzheimer's disease, which are similar to those of other IV in vitro diagnostics that have undergone premarket review.

        The FDA has announced that in the future it intends to assert jurisdiction over LDTs and proposed increasing regulatory requirements for LDTs through a risk-based framework. The FDA received considerable resistance to its proposal, and to date generally exercises enforcement discretion with respect to LDTs, leaving responsibility to CMS.

        New laws, regulations or changes to existing laws, regulations and policies may result in changes to the requirements for LDTs or in vitro diagnostic devices and to the FDA's compliance and enforcement policies.

Healthcare Regulation

        Our ability to successfully commercialize any of our product candidates for which we may receive regulatory approval will depend in significant part on the availability of coverage and reimbursement from third-party payors, including governmental healthcare programs such as the Medicare and Medicaid programs in the U.S.; private health insurers; managed care organizations; and other entities. Third-party payors establish the coverage and reimbursement policies for pharmaceutical products, and the marketability of any products for which we may receive regulatory approval for commercial sale depends on those payors' coverage policies and reimbursement rates. Third-party payors may limit coverage to specific products on an approved list, or formulary, which might not include one or more of our product candidates. Third-party payors, together with regulators and others, are increasingly challenging the prices charged for pharmaceutical products and health services, in addition to their cost-effectiveness, safety and efficacy.

        In addition, no uniform policy for coverage and reimbursement exists in the United States. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies, but also have their own methods and approval process apart from Medicare determinations. Therefore, coverage and reimbursement rates can vary significantly from payor to payor.

        Moreover, obtaining coverage and adequate reimbursement is a time-consuming and costly process. We may be required to provide scientific and clinical support for the use of any product to each third-party payor separately with no assurance that approval will be obtained, and we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the cost-effectiveness of our products. We cannot be

123


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

certain that our product candidates will be considered cost-effective by third-party payors. This process could delay the market acceptance of any product candidates for which we may receive approval and could have a negative effect on our future revenues and operating results.

        In the United States, our business may be subject to healthcare fraud and abuse regulation and enforcement by both the federal government and the states in which we conduct our business, particularly once third-party reimbursement becomes available for one or more of our products. The healthcare fraud and abuse laws and regulations that may affect our ability to operate include but are not limited to:

124


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

        We will be required to spend substantial time and money to ensure that our business arrangements with third parties comply with applicable healthcare laws and regulations. Even then, governmental authorities may conclude that our business practices do not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If governmental authorities find that our operations violate any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion from government funded healthcare programs, such as Medicare and Medicaid, and additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, and we may be required to curtail or restructure our operations. Moreover, we expect that there will continue to be federal and state laws and regulations, proposed and implemented, that could impact our operations and business. In addition, the approval and commercialization of any product candidate we develop outside the United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws. The extent to which future legislation or regulations, if any, relating to health care fraud and abuse laws or enforcement, may be enacted or what effect such legislation or regulation would have on our business remains uncertain.

        In the United States there have been, and continue to be, several legislative and regulatory changes and proposed reforms of the healthcare system to contain costs, improve quality and expand access to care. In the United States, there have been and continue to be a number of healthcare-related legislative initiatives that have significantly affected the pharmaceutical industry. For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively, the ACA, was passed in March 2010, substantially changing the way healthcare is financed by both governmental and private insurers and significantly impacting the U.S. pharmaceutical industry. Among other things, the ACA subjects biologics to potential competition by lower-cost biosimilars; addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected; increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations; establishes annual fees and taxes on manufacturers of certain branded prescription drugs; and creates a new Medicare Part D coverage gap discount program in which, as a condition of coverage of its products under Medicare Part D, manufacturers must now agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period.

        Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges. In addition, there have been efforts by the Trump Administration to repeal or replace certain aspects of the ACA and to alter the implementation of the ACA and related laws. For example, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or the Tax Act, includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year commonly referred to as the "individual mandate." On January 22, 2018, President Trump signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain ACA-mandated fees, including the so-called "Cadillac" tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based on market share and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act of 2018, or the BBA, among other things, amends the ACA, effective January 1, 2019, to reduce the coverage gap in most Medicare drug plans, commonly referred to as the "donut hole." Also, in 2018, CMS issued final rules permitting further collections and payments to and from certain ACA qualified health plans and health insurance issuers under the ACA risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. Additional legislative changes or regulatory changes related to the ACA remain possible. In December 2018, a United States District Court Judge for the Northern District of Texas ruled that the entire ACA is invalid as a result of the tax penalty associated with the "individual mandate" being repealed by Congress as part of the Tax Act. This ruling is under appeal and stayed pending appeal. It is unclear how this decision, subsequent appeals and other efforts to repeal, replace or invalidate the ACA, regulations promulgated under the ACA or portions thereof, will impact the ACA and its implementation or our business.

        Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing; reduce the cost of prescription drugs under Medicare; review the relationship between pricing and manufacturer patient programs; and reform government program reimbursement methodologies for drugs. The Trump Administration's budget proposals for fiscal 2019 and 2020 contain drug price control measures, including measures to permit Medicare Part D plans to

126


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid and to eliminate cost sharing for generic drugs for low-income patients. Further, the Trump Administration released a "Blueprint" to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out of pocket costs of drug products paid by consumers. HHS has started soliciting feedback on some of these measures and, at the same, is implementing others under its existing authority. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020. This final rule codified CMS's policy change that was effective January 1, 2019. Although a number of these measures may require additional authorization to become effective, Congress and the Trump Administration have each indicated that they will continue to seek new legislative and/or administrative measures to control drug costs. Individual states in the United States have also increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement limitations, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs.

        Moreover, on May 30, 2018, the Right to Try Act was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

Employees

        As of October 23, 2019, we had 67 full-time employees, of which 52 were primarily engaged in research and development activities and 27 hold M.D. or Ph.D. degrees. None of our employees is represented by labor unions or covered by collective bargaining agreements. We consider our relationship with our employees to be good.

Facilities

        Our corporate headquarters are located in Beltsville, Maryland and consist of 11,329 square feet of office space, 13,579 square feet of laboratory and manufacturing space and 10,209 square that we are in the process of converting into office space, or collectively the Current Space, under a lease that expires in August 2025, or the Original Lease. In June 2019, we took possession of an additional 14,075 square feet of space to be used for future office, laboratory and manufacturing space under a new lease entered into in January 2019, or the New Lease. In August 2019, we entered into an amendment to the New Lease for an additional 14,446 square feet to be used for future office, laboratory and manufacturing space, which we expect the landlord to deliver in April 2020. The New Lease expires in March 2030 and will also cover the Current Space upon expiration of the Original Lease. We believe that these facilities are adequate for our current needs and that suitable additional or substitute space will be available in the future if needed.

Legal Proceedings

        From time to time, we may become involved in litigation or other legal proceedings as part of our ordinary course of business. We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business.

        We believe that Dr. Xu is qualified to serve on our board of directors due to her extensive, global experience in the development and commercialization of innovative therapies.

Board Composition and Diversity

        Our board of directors currently consists of nine members. Each of our current directors will continue to serve until the election and qualification of his or her successor, or his or her earlier death, resignation or removal.

        Our nominating and corporate governance committee is responsible for reviewing with the board of directors, on an annual basis, the appropriate characteristics, skills and experience required for the board of directors as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current members), the nominating and corporate governance committee, in recommending candidates for election, and the board of directors, in approving (and, in the case of vacancies, appointing) such candidates, may take into account many factors, including but not limited to the following:

        We have no formal policy regarding board diversity. Our board of directors evaluates each individual in the context of the board of directors as a whole, with the objective of assembling a group that can best maximize the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas.

Director Independence

        Our board of directors has determined that none of our directors other than Mr. Richman has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is "independent" as that term is defined under Nasdaq rules. There are no family relationships among any of our directors or executive officers. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director and the transactions involving them described in the section entitled "Certain Relationships and Related Party Transactions."

Board Leadership Structure

        Dr. Kabakoff currently serves as Chair of our board of directors. Our board of directors believes that separation of the positions of Chair and Chief Executive Officer reinforces the independence of our board of directors from management, creates an environment that encourages objective oversight of management's performance and enhances the effectiveness of our board of directors as a whole, and has concluded that our current board leadership structure is appropriate at this time. However, our amended and restated bylaws and corporate governance guidelines provide our board of directors with flexibility to combine or separate the positions of Chair and Chief Executive Officer and to appoint a lead director in accordance with its determination that utilizing one or the other structure would be in the best interests of our company. Our board of directors will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Classified Board of Directors

        In accordance with our amended and restated certificate of incorporation, our board of directors is divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our directors are divided among the three classes as follows:

        Our amended and restated certificate of incorporation provides that the authorized number of directors may be changed only by resolution of the board of directors. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. The division of our board of directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of our company.

Role of the Board in Risk Oversight

        Risk assessment and oversight are an integral part of our governance and management processes. Our board of directors encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the board of directors at regular board meetings as part of management presentations that focus on particular business functions, operations or strategies and presents the steps taken by management to mitigate or eliminate such risks.

        Our board of directors does not have a standing risk management committee, but rather administers this oversight function directly through our board of directors as a whole, as well as through various standing committees of our board of directors that address risks inherent in their respective areas of oversight. In particular, our board of directors is responsible for monitoring and assessing strategic risk exposure and our audit committee is responsible for overseeing our major financial risk exposures and the steps our management has taken to monitor and control these exposures. The audit committee also monitors compliance with legal and regulatory requirements and considers and approves or disapproves

any related person transactions. Our nominating and corporate governance committee monitors the effectiveness of our corporate governance practices and of our board of directors. Our compensation committee assesses and monitors whether any of our compensation policies and programs have the potential to encourage excessive risk-taking. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, our entire board of directors is regularly informed about such risks through committee reports.

Board Committees

        Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee. Each of these committees operates under a written charter approved by our board of directors that satisfies applicable SEC and Nasdaq standards. From time to time, our board of directors may establish other committees to facilitate the management of our business. Each committee's charter is available under the Governance section of our website at www.nextcure.com. The reference to our website address does not constitute incorporation by reference of the information contained at or available through our website.

Audit Committee

        The primary function of our audit committee is to oversee our corporate accounting and financial reporting process. Our audit committee's responsibilities include:

        The members of our audit committee are Dr. Kabakoff, Ms. Li and Mr. Webster and Mr. Webster serves as the chair of the committee. Our board of directors has determined that each of the members of our audit committee satisfies the financial literacy and sophistication requirements of the SEC and the Nasdaq listing rules. In addition, our board of directors has determined that Mr. Webster qualifies as an audit committee financial expert under SEC rules. Under SEC rules, members of our audit committee must also meet heightened independence standards. Our board of directors has determined that each of the members of our audit committee is independent under the applicable SEC and Nasdaq listing rules.

Compensation Committee

        Our compensation committee oversees policies relating to compensation and benefits of our officers and employees. The compensation committee reviews and approves or recommends corporate goals and objectives relevant to compensation of our executive officers, evaluates the performance of these officers in light of those goals and objectives and approves the compensation of these officers based on such evaluations. The compensation committee also reviews and approves or makes recommendations to our board of directors regarding the issuance of stock options and other awards to our executive officers. The

compensation committee will review and evaluate, at least annually, the performance of the compensation committee and its members, including compliance by the compensation committee with its charter. The members of our compensation committee are Dr. Shannon, Mr. Khuong, Dr. Kabakoff and Dr. Morrison and Dr. Shannon serves as chair of the committee. Each of the members of our compensation committee is independent under the applicable Nasdaq listing rules and is a "non-employee director" as defined in Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act.

Nominating and Corporate Governance Committee

        Our nominating and corporate governance committee is responsible for making recommendations to our board of directors regarding candidates for directorships and the size and composition of our board of directors. In addition, our nominating and corporate governance committee is responsible for overseeing our corporate governance policies and reporting and making recommendations to our board of directors concerning governance matters. The members of our nominating and corporate governance committee are Dr. Jones, Mr. Khuong, Dr. Shannon and Dr. Xu and Dr. Jones serves as chair of the committee. Each of the members of our nominating and corporate governance committee is independent under the applicable Nasdaq listing rules.

Compensation Committee Interlocks and Insider Participation

        None of the members of our compensation committee has ever served as one of our officers or employees. None of our executive officers serves, or has served during the last three fiscal years, as a member of the board of directors, compensation committee or other board committee performing equivalent functions of any entity that has one or more executive officers serving as one of our directors or on our compensation committee.

Code of Business Conduct and Ethics

        We adopted a code of business conduct and ethics that applies to all of our directors, officers and employees, including those officers responsible for financial reporting. A current copy of the code of business conduct and ethics is available under the Corporate Governance section of our website. We intend to disclose future amendments to the code or any waivers of its requirements on our website. The reference to our website address does not constitute incorporation by reference of the information contained at or available through our website.

Limitation on Liability and Indemnification Matters

        Our amended and restated certificate of incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for:

        Our amended and restated bylaws provide that we are required to indemnify our directors and officers, in each case to the fullest extent permitted by Delaware law. Our amended and restated bylaws also obligate us to advance expenses incurred by a director or officer in advance of the final disposition of

136


Table of Contents

any action or proceeding and permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of such person's actions in that capacity regardless of whether we would otherwise be permitted to indemnify such person under Delaware law. We have entered and expect to continue to enter into agreements to indemnify our directors, executive officers and other employees as determined by our board of directors. These indemnification agreements generally require us, among other things, to indemnify our directors, executive officers and these employees against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct. These indemnification agreements also generally require us to advance any expenses incurred by the directors, executive officers and employees as a result of any proceeding against them as to which they could be indemnified. We believe that these provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also maintain directors' and officers' liability insurance that insures our directors and officers against the cost of defense, settlement or payment of a judgment in some circumstances.

        The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage stockholders from bringing a lawsuit against our directors and officers for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and our stockholders. Further, a stockholder's investment may be adversely affected to the extent that we pay the costs of settlement and damage.

Non-Employee Director Compensation

        In the year ended December 31, 2018, we did not pay any fees to, or make any equity or non-equity awards to, or pay any other compensation to the non-employee members of our board of directors for their services as directors, except that we granted Dr. Kabakoff an option to purchase 37,342 shares of our common stock at an exercise price of $7.63 per share. Prior to our IPO, we did not compensate any of our other non-employee directors for service on our board of directors. We did reimburse our non-employee directors for travel and other necessary business expenses incurred in the performance of their service as directors.

        In connection with our IPO, our board of directors approved a compensation program for our non-employee directors, or the Non-Employee Director Compensation Program. Pursuant to this program, our non-employee directors receive annual cash compensation as follows:

        All fees under the Non-Employee Director Compensation Program are paid quarterly in arrears and are pro-rated for any partial quarters of service, and no per meeting fees are paid, except that we reimburse non-employee directors for reasonable expenses incurred in connection with attending board and committee meetings.

        Under the Non-Employee Director Compensation Program, each non-employee director is also entitled to receive an annual stock option award to purchase 11,000 shares of our common stock that vests on the earlier of one year from the grant date of the award or the date of the next annual meeting of the

137


Table of Contents

stockholders, subject to continued service through the vesting date. Annual stock option grants for non-employee directors who were initially elected in the 12 months preceding the annual grant date will be pro-rated on a monthly basis for time in service. In addition, each non-employee director who is elected or appointed to our board of directors is entitled to receive an initial stock option award to purchase 22,000 shares of our common stock that vests in three equal annual installments commencing on the grant date of the award, subject to continued service through the applicable vesting date. All stock options granted pursuant to the Non-Employee Director Compensation Program are subject to the terms and provisions of the 2019 Plan.

Director Compensation Table

        As described above, we did not pay any cash or grant any stock awards or other compensation to our non-employee directors during 2018 for their services as non-employee directors, except for the option granted to Dr. Kabakoff. Except as described below for Dr. Kabakoff, there were no outstanding stock awards or option awards held by our non-employee directors as of December 31, 2018. The table below sets forth information on the compensation of all our non-employee directors for the year ended December 31, 2018. Michael Richman, our President and Chief Executive Officer, is also a member of our board of directors, but did not receive any additional compensation for his service as a director.

Mr. Cobourn's employment commenced with us on January 22, 2018. The 2018 salary reported reflects the pro rata portion of Mr. Cobourn's annual salary of $250,000 earned during 2018 from commencement of his employment through December 31, 2018.

Narrative to Summary Compensation Table

Annual Base Salary

        We have entered into employment agreements with each of our NEOs that establish annual base salaries, which are generally determined, approved and reviewed periodically by our board of directors in order to compensate our NEOs for services rendered to our company. The base salary payable to each NEO is intended to provide a fixed component of compensation reflecting the executive's skill set, experience, role and responsibilities. Base salaries for our NEOs have generally been set at levels deemed necessary to attract and retain individuals with superior talent. In March 2018, the annual base salaries of Mr. Richman and Dr. Langermann were increased by 3% and 2.5% to $386,200 and $343,050, respectively. Mr. Cobourn's annual base salary for 2018 was $250,000.

Annual Bonus and Non-Equity Incentive Plan Compensation

        Our NEOs are eligible to receive annual bonuses, which are determined at the discretion of our board of directors based upon, among other things, the achievement of pre-determined performance milestones. For 2018, Mr. Richman and Dr. Langermann were each eligible to receive a target bonus of up to 35% and 25%, respectively, of his base salary. Our board of directors reviewed performance for the fiscal year 2018 and based on the level of achievement of performance milestones determined to pay these bonuses at target with the exception of Mr. Richman, who received a bonus of 40% of his base salary, which was above his target. At the time Mr. Cobourn joined our company in 2018, our board of directors did not set a target bonus percentage for Mr. Cobourn. Mr. Cobourn's bonus was determined by our board of directors using the same pre-determined performance milestones used for our other NEOs and represented 25% of his base salary pro-rated to reflect his start date of January 22, 2018.

Equity Awards

        Although we do not have a formal policy with respect to the grant of equity incentive awards to our NEOs, we believe that equity grants provide our NEOs with a strong link to our long-term performance, create an ownership culture and help to align the interests of our NEOs and our stockholders. Our board of directors and compensation committee has historically been responsible for approving NEO equity grants, Our compensation committee is generally responsible for approving NEO equity grants. Vesting of equity awards is generally tied to continuous service with us and serves as an additional retention measure. Our NEOs generally are awarded an initial new hire grant upon commencement of employment. Additional grants may occur periodically in order to specifically incentivize executives with respect to achieving certain goals or to reward NEOs for exceptional performance. Prior to our IPO, we granted all awards pursuant to our 2015 Omnibus Incentive Plan, or the 2015 Plan, the terms of which are described below under "—Equity Compensation Plans—2015 Omnibus Incentive Plan."

        In August 2018, our board of directors awarded Mr. Richman an option to purchase 118,249 shares of our common stock, Mr. Cobourn an option to purchase 74,684 shares of our common stock and Mr. Langermann an option to purchase 24,894 shares of our common stock, each at an exercise price of $1.77 per share. In December 2018, our board of directors awarded Mr. Richman an option to purchase 373,422 shares of our common stock, Mr. Cobourn an option to purchase 124,474 shares of our common stock and Dr. Langermann an option to purchase 87,131 shares of our common stock, each at an exercise price of $7.63 per share. With respect to each of the grants disclosed above, 25% vest on the one-year anniversary of the grant date, and, thereafter, 1/36th of the remaining options vest on each monthly anniversary of the grant date.

Outstanding Equity Awards at Fiscal Year-End

Equity Compensation Plans

2015 Omnibus Incentive Plan

        Our board of directors adopted, and our stockholders approved the 2015 Plan on December 29, 2015, which was subsequently amended to increase the number of shares issuable under the 2015 Plan. The 2015 Plan is intended to enhance our company's ability to attract and retain highly qualified officers, directors, key employees and other persons, and to motivate such persons to serve us and our affiliates and to expend maximum effort to improve the business results and our earnings, by providing to such persons an opportunity to acquire or increase a direct proprietary interest in our operations and our future success. The 2015 Plan provides for the grant of stock options, restricted stock and stock units. No further awards will be made under the 2015 Plan; however, awards outstanding under the 2015 Plan will continue to be governed by their existing terms.

        As of June 30, 2019, options to purchase 2,027,502 shares of our common stock were outstanding under the 2015 Plan, 5,186 unvested shares of restricted stock were outstanding under the 2015 Plan. If any shares covered by an award granted under the 2015 Plan are not purchased or are forfeited, expire or

142


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

otherwise terminate without delivery of any shares subject to the award, or are settled in cash in lieu of shares, then the number of shares subject to such award will, to the extent of any such forfeiture, termination, expiration or settlement, again be available for future issuance under the 2019 Plan.

        The compensation committee of our board of directors generally administers the 2015 Plan. The administrator has complete discretion to make all decisions relating to the 2015 Plan and outstanding awards.

        In the event of a recapitalization, reclassification, stock split, reverse stock split, spin-off, combination of shares, exchange of shares, stock dividend or other distribution payable in capital stock, or other increase or decrease in our shares of common stock effected without the receipt of consideration by us, then the number and kind of shares for which grants of options and other awards may be made under the 2015 Plan will be adjusted proportionately and accordingly by the administrator of the 2015 Plan. In addition, the number and kind of shares for which awards are outstanding, as well as the exercise price of outstanding options will be adjusted proportionately and accordingly by the administrator of the 2015 Plan.

        Our board of directors has the discretion to determine the effect of a "corporate transaction" (as defined in the 2015 Plan) on any outstanding awards. Without limiting the generality of the foregoing, in connection with a corporate transaction, our board of directors may elect, in its sole discretion, to:

        If we establish an exercise window in connection with a scheduled consummation of a corporate transaction, any exercise of an option during such period will be conditioned upon the consummation of the event and will be effective only immediately before the consummation of the event. Upon the consummation of any corporate transaction, the 2015 Plan and all outstanding but unexercised options will terminate. Our board of directors will send written notice of an event that will result in such a termination

143


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

to all individuals who hold options not later than the time at which we give notice of the event to the holders of our common stock.

        Our board of directors may, in its sole discretion, provide for the accelerated vesting or lapse of restrictions of awards at any time.

        Our board of directors may amend or terminate the 2015 Plan or any outstanding award under the 2015 Plan at any time; provided that no amendment may adversely impair a participant's rights under outstanding awards without his or her consent. Our stockholders must approve any amendment if such approval is required under applicable law or Nasdaq listing rules. Unless terminated sooner by our board of directors or extended with stockholder approval, the 2015 Plan will terminate on December 29, 2025.

2019 Omnibus Incentive Plan

        Our board of directors adopted our 2019 Omnibus Incentive Plan, or the 2019 Plan, in April 2019 and our stockholders approved the 2019 Plan in May 2019. The 2019 Plan became effective on May 8, 2019 upon the effectiveness of the registration statement for our IPO. The purpose of the 2019 Plan is to provide eligible individuals with an incentive to contribute to our success and to operate and manage our business in a manner that will provide for our long-term growth and profitability and that will benefit our stockholders and other important stakeholders, including our employees and customers. The 2019 Plan is also intended to provide a means of recruiting, rewarding and retaining key personnel. The 2019 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, deferred stock units, unrestricted stock, dividend equivalent rights, other equity-based awards and cash bonus awards. The 2019 Plan replaces the 2015 Plan; however, awards outstanding under the 2015 Plan will continue to be governed by their existing terms.

        The number of shares of our common stock reserved for issuance under the 2019 Plan is equal to the sum of (i) 2,900,000 shares plus (ii) any shares related to awards outstanding under the 2015 Plan on May 8, 2019 that subsequently terminate by expiration or forfeiture, cancellation, or otherwise without the issuance of such shares. The number of shares reserved for issuance under the 2019 Plan will automatically increase on January 1st of each year during the term of the 2019 Plan, by a number equal to 4% of the shares of common stock outstanding on December 31st of the prior calendar year; however, our board of directors may provide that there will be no increase, or a smaller increase, in the share reserve for a given calendar year. As of June 30, 2019, options to purchase 210,275 shares of our common stock were outstanding under the 2019 Plan and 2,689,725 additional shares of our common stock remained available for future issuance.

        If any shares covered by an award granted under the 2019 Plan are not purchased or are forfeited or expire or otherwise terminate without delivery of any shares subject to the award, or are settled in cash in lieu of shares, then the number of shares subject to such award will, to the extent of any such forfeiture, termination, expiration or settlement, again be available for future issuance under the 2019 Plan. In addition, if shares subject to an award are applied to the exercise price or tax withholding obligations related to the award, such shares will again be available for future issuance under the 2019 Plan.

        The 2019 Plan is administered by our board of directors or a committee of our board of directors to which our board of directors delegates such administration (as applicable, the administrator). Subject to the terms of the 2019 Plan, the administrator has the complete discretion to determine the eligible individuals who are to receive awards under the 2019 Plan, to determine the terms and conditions of

144


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

awards granted under the 2019 Plan and to make all decisions related to the 2019 Plan and awards granted thereunder. The administrator also interprets the provisions of the 2019 Plan. Our board of directors has delegated full authority to administer the 2019 Plan to its compensation committee.

        All of our employees and the employees of our affiliates are eligible to receive awards under the 2019 Plan. In addition, our non-employee directors and certain consultants and advisors who perform services for us and our affiliates may receive awards under the 2019 Plan. However, only our employees and our subsidiaries are eligible to receive incentive stock options.

        The 2019 Plan authorizes our compensation committee to grant incentive stock options (under Section 422 of the Internal Revenue Code of 1986, as amended, or the Code) and stock options that do not qualify as incentive stock options, or non-qualified stock options. The maximum number of shares that may be issued under the 2019 Plan pursuant to the exercise of incentive stock options is 8,700,000. The compensation committee will determine the exercise price of each stock option, provided that the price must be equal to at least the fair market value of our shares of common stock on the date on which the stock option is granted. If we were to grant incentive stock options to any 10% stockholder, the exercise price may not be less than 110% of the fair market value of our shares of common stock on the date of grant.

        The term of a stock option cannot exceed 10 years from the date of grant. If we were to grant incentive stock options to any 10% stockholder, the term cannot exceed five years from the date of grant. The compensation committee will determine at what time or times each stock option may be exercised and the period of time, if any, after death, disability or termination of employment during which stock options may be exercised. Stock options may be made exercisable in installments. The compensation committee may accelerate the exercisability of stock options.

        The aggregate fair market value, determined at the time of grant, of our common stock with respect to incentive stock options that are exercisable for the first time by a grantee during any calendar year under all of our stock plans may not exceed $100,000. We will generally treat stock options or portions thereof that exceed such limit as non-qualified stock options.

        The 2019 Plan authorizes our compensation committee to grant stock appreciation rights that provide the recipient with the right to receive, upon exercise of the stock appreciation right, cash, shares of our common stock or a combination of the two. The amount that the recipient will receive upon exercise of the stock appreciation right generally will equal the excess of the fair market value of our common stock on the date of exercise over the shares' fair market value on the date of grant. Stock appreciation rights will become exercisable in accordance with terms determined by our compensation committee. Stock appreciation rights may be granted in tandem with a stock option grant or independently from a stock option grant. The term of a stock appreciation right cannot exceed 10 years from the date of grant.

        The 2019 Plan authorizes our compensation committee to grant restricted stock, restricted stock units and deferred stock units. Restricted stock is an award of our common stock on which vesting restrictions are imposed that subject such shares of our common stock to a substantial risk of forfeiture, as defined in Section 83 of the Code. A restricted stock unit is an award that represents the right to receive a compensation amount, based on the value of our shares of common stock, if vesting criteria established by the compensation committee are met. If the vesting criteria are met, we will settle restricted stock units in

145

Pursuant to 17 C.F.R. Section 200.83

cash, shares of our common stock or a combination of the two. A deferred stock unit is a restricted stock unit that may be settled at some point in the future at a time or times consistent with the requirements of Section 409A of the Code.

        Subject to the provisions of the 2019 Plan, our compensation committee will determine the terms and conditions of each award of restricted stock, restricted stock units and deferred stock units, including the restricted period for all or a portion of the award, the restrictions applicable to the award and the purchase price, if any, for the shares of our common stock subject to the award. A grantee of restricted stock will have all the rights of a stockholder, including the right to vote the shares and receive dividends, except to the extent limited by our compensation committee. However, all cash dividends declared or paid on shares of restricted stock will not vest or become payable unless and until the shares of restricted stock to which the dividends apply become vested and nonforfeitable. In addition, all stock dividend payments or distributions, if any, received by a grantee with respect to shares of restricted stock as a result of any stock split, stock dividend, combination of stock or other similar transaction will be subject to the same vesting conditions and restrictions as applicable to such underlying shares of restricted stock.

        Grantees of restricted stock units and deferred stock units will have no voting or dividend rights or other rights associated with stock ownership, although our compensation committee may award dividend equivalent rights on such units. Dividend equivalent rights granted as a component of another award will not vest or become payable unless and until the award to which the dividend equivalent rights correspond becomes vested and settled.

        The 2019 Plan authorizes our compensation committee to grant dividend equivalent rights in connection with the grant of any equity-based award other than stock options and stock appreciation rights. Dividend equivalent rights entitle the grantee to receive, or to receive credits for the future payment of, cash, shares of our common stock or other property equal in value to dividend payments or distributions declared or paid by us with respect to a number of shares of our common stock specified in such dividend equivalent right (or other award to which such right relates), as if such shares had been issued to and held by the grantee as of the record date of such dividend or distribution. Dividend equivalent rights may be paid currently or may be deemed to be reinvested in additional shares of stock, which may thereafter accrue additional dividend equivalent rights and may be payable in cash, shares of our common stock or a combination of the two; however, dividend equivalent rights granted as a component of another award will not vest or become payable unless and until the award to which the dividend equivalent rights correspond becomes vested and settled. Our compensation committee will determine the terms of any dividend equivalent rights.

        The 2019 Plan authorizes our compensation committee to grant other types of equity-based awards under the 2019 Plan. Other equity-based awards may be granted with vesting, value and/or payment contingent upon the achievement of one or more performance goals or other vesting conditions, and may be payable in cash, shares of our common stock or a combination thereof. The terms and conditions that apply to other equity-based awards will be determined by our compensation committee.

        The 2019 Plan provides that the aggregate value of all awards granted under the plan and all other cash compensation paid by us to any of our non-employee directors in any calendar year may not exceed $750,000; however, such amount will be $1.0 million for the calendar year in which the non-employee director is initially elected or appointed to our board of directors. Our board of directors may make exceptions to these limitations for individual non-employee directors in extraordinary circumstances,

146

Pursuant to 17 C.F.R. Section 200.83

provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation or in other contemporaneous compensation decisions involving non-employee directors.

        In the event of a recapitalization, reclassification, stock split, reverse stock split, spin-off, combination of shares, exchange of shares, stock dividend or other distribution payable in capital stock, or other increase or decrease in our shares of common stock effected without the receipt of consideration by us, then the number and kind of shares for which grants of options and other awards may be made under the 2019 Plan, including the maximum number of shares that may be issued upon the exercise of incentive stock options, will be adjusted proportionately and accordingly by our compensation committee. In addition, the number and kind of shares for which awards are outstanding, as well as the exercise price of outstanding options and stock appreciation rights, will be adjusted proportionately and accordingly by our compensation committee.

        Except as otherwise provided in the applicable award agreement, in another agreement with a grantee, or as otherwise set forth in writing, upon the occurrence of a "change in control" (as defined in the 2019 Plan) in which outstanding awards are not being assumed, continued or substituted for, the following provisions will apply to the awards: (i) except for performance-based awards, all shares of restricted stock, restricted stock units, deferred stock units and dividend equivalent rights will be deemed to have vested and any underlying shares of our common stock will be deemed delivered immediately before the change in control; and (ii) at our compensation committee's discretion, either all options and stock appreciation rights will become exercisable 15 days before the change in control (with any exercise of an option or stock appreciation right during such 15 day period to be contingent upon the consummation of the change in control) and terminate upon the change in control to the extent not exercised, or all options, stock appreciation rights, shares of restricted stock, restricted stock units, deferred stock units and/or dividend equivalent rights will be canceled and cashed out in connection with the change in control.

        In the case of performance-based awards, if less than half of the performance period has lapsed, the award will be treated as though target performance has been achieved. If at least half of the performance period has lapsed, actual performance to date will be determined as of a date reasonably proximal to the date of the consummation of the change in control, as determined by our compensation committee in its sole discretion, and that level of performance will be treated as achieved immediately prior to the occurrence of the change in control. If our compensation committee determines that actual performance is not determinable, the award will be treated as though target performance has been achieved. Any awards that arise after performance is determined in accordance with this paragraph will be treated as set forth in the preceding paragraph. Other equity-based awards will be governed by the terms of the applicable award agreement.

        If we experience a change in control in which outstanding awards will be assumed, continued or substituted for by the surviving entity, then, except as otherwise provided in the applicable award agreement, in another agreement with a grantee, or as otherwise set forth in writing, upon the occurrence of the change in control, the 2019 Plan and the awards granted under the 2019 Plan will continue in the manner and under the terms so provided in the event of the change in control to the extent that provision is made in writing in connection with such change in control for the assumption or continuation of such awards, or for the substitution for such awards with new awards, with appropriate adjustments as to the number of shares (disregarding any consideration that is not common stock) and exercise prices of options and stock appreciation rights.

        Except as otherwise provided in the applicable award agreement, in another agreement with a grantee, or as otherwise set forth in writing, in the event a grantee's award is assumed, continued, or substituted upon the consummation of any change in control and the service of such grantee with us or an affiliate of ours is terminated without "cause" (as defined in the 2019 Plan) within 12 months following the consummation of such change in control, such award will become fully vested and may be exercised in full, to the extent applicable, beginning on the date of such termination and for the one-year period, or such longer period as may be determined by our compensation committee, immediately following such termination.

        All awards will be subject to mandatory repayment to us by a grantee to the extent the grantee is, or in the future becomes, subject to (i) any "clawback" or recoupment policy by us or any of our affiliates that is adopted to comply with the requirements of any applicable laws, or (ii) any applicable laws which impose mandatory recoupment, under circumstances set forth in such applicable laws. Except in limited circumstances, awards granted under the 2019 Plan may generally not be transferred in any manner prior to vesting other than by will or by the laws of descent and distribution.

        Our compensation committee may amend or terminate the 2019 Plan at any time; provided that no amendment may materially impair a participant's rights under outstanding awards without his or her consent. Our stockholders must approve any amendment if such approval is required under applicable law or Nasdaq listing rules. Unless terminated sooner by our board of directors or extended with stockholder approval, the 2019 Plan will terminate on the day before the tenth anniversary of the effective date of the registration statement of which this prospectus is a part.

        Except in connection with certain corporate transactions, we may not, without obtaining stockholder approval: (i) amend the terms of outstanding options or stock appreciation rights to reduce the applicable exercise price; (ii) cancel outstanding options or stock appreciation rights in exchange for or substitution of options or stock appreciation rights with an exercise price that is less than the exercise price of the original options or stock appreciation rights; or (iii) cancel outstanding options or stock appreciation rights with an exercise price above the current stock price in exchange for cash or other securities.

2019 Employee Stock Purchase Plan

        Our board of directors adopted the ESPP in April 2019 and our stockholders approved the ESPP in May 2019. The ESPP became effective on May 8, 2019 upon the effectiveness of the registration statement for our IPO. The purpose of the ESPP is to encourage and to enable eligible employees to acquire proprietary interests in our company through the purchase and ownership of shares of our common stock. The ESPP is intended to benefit us and our stockholders by incentivizing participants to contribute to our success and to operate and manage our business in a manner that will provide for our long-term growth and profitability and that will benefit our stockholders and other important stakeholders. The ESPP is intended to qualify as an "employee stock purchase plan" within the meaning of Section 423 of the Code.

        The ESPP authorizes the issuance of up to 240,000 shares of our common stock pursuant to purchase rights granted to our employees or to employees of any of our participating affiliates. The number of shares of our common stock reserved for issuance will automatically increase on January 1st of each year, commencing on January 1, 2020 and continuing until the expiration of the ESPP, in an amount equal to the

148


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

least of (i) 1% of the total number of shares of our common stock outstanding on December 31st of the preceding calendar year, (ii) 480,000 shares of our common stock (subject to adjustment as provided in the ESPP) and (iii) a number of shares of our common stock determined by our board of directors or our compensation committee, as applicable; however, our board of directors or our compensation committee, as applicable, may act prior to the first day of any calendar year to provide that there will be no increase in the share reserve for such calendar year.

        The ESPP is administered under the direction of our board of directors, our compensation committee, or any other committee designated by our board of directors. Our board of directors has delegated full authority to administer the ESPP to its compensation committee. Among other things, the compensation committee has the authority to determine eligibility for participation in the ESPP, designate separate offerings under the plan and construe, interpret and apply the terms of the plan.

        All of our employees who are employed by us or our participating affiliates may be eligible to participate in the ESPP, provided that the following employees are among those that are ineligible under the ESPP: (i) employees whose customary employment is 20 hours or less per week; (ii) employees whose customary employment is for not more than five months in any calendar year; and (iii) employees who, after exercising their rights to purchase our common stock under the ESPP, would own 5% or more of our total combined voting power.

        No employee may purchase shares of our common stock in any calendar year under the ESPP and under all other employee stock purchase plans having an aggregate fair market value in excess of $25,000, determined as of the first trading day of the offering period. In addition, unless otherwise determined by our compensation committee, no employee may purchase more than 5,000 shares of our common stock in any one offering period.

        The ESPP is being implemented through a series of offerings under which eligible employees are granted purchase rights to purchase our common stock on specified dates during such offerings. Our compensation committee will determine offering periods of not more than 27 months and may permit periodic purchases of our common stock within a single offering period. Unless otherwise established by our compensation committee prior to the start of an offering period, the plan will have two offering periods (with concurrent purchase periods) that commence each calendar year, and each offering period will be of approximately six months' duration, with the first such offering period beginning on the first trading day of April and ending on the last trading day of the immediately following September, and the second such offering period beginning on the first trading day of October and ending on the last trading day of the immediately following March.

        Generally, all employees, including executive officers, employed by us or by any of our participating affiliates, may participate in the ESPP and may contribute, normally through payroll deductions, up to 15% of their eligible compensation for the purchase of our common stock under the ESPP. Unless otherwise determined by our compensation committee, the purchase price per share of our common stock under the ESPP will be 85% of the lesser of the average of the high and low sales price of our common stock on (i) the first trading day of the relevant offering period and (ii) the last trading day of the relevant offering period (or, if the relevant offering period has multiple purchase periods, the last trading day of the relevant purchase period).

149

Pursuant to 17 C.F.R. Section 200.83

        Our compensation committee has the right to (i) require that an employee not request that all or a part of the shares of our common stock purchased by the employee be reissued in the employee's own name and shares be delivered to the employee until two years have elapsed since the offering date of the offering period in which the shares of our common stock were purchased and one year has elapsed since the day the shares of our common stock were purchased, or the holding period, (ii) require that any sales of our common stock during the holding period be performed through a licensed broker acceptable to us and (iii) limit sales or other transfers of shares of our common stock for up to two years from the date the employee purchases shares of our common stock under the ESPP.

        In the event that there occurs a change in our capital structure through such actions as a recapitalization, stock split, reverse stock split, spin-off, combination of shares, exchange of shares, stock dividend or other distribution payable in capital stock, our compensation committee will make appropriate adjustments to the number and kind of shares that may be purchased, and the number and kind of shares for which options are outstanding, under the ESPP.

        In the event of certain significant corporate transactions, including (i) a dissolution or liquidation, (ii) a merger, consolidation or reorganization where we are not the surviving entity, (iii) a sale of all or substantially all of our assets, or (iv) a merger or consolidation resulting in any person or entity owning more than 50% of the combined voting power of all classes of our capital stock, the ESPP and all elections outstanding under the ESPP will terminate, except for certain situations where, for instance, the parties make arrangements for the continuation or assumption of the ESPP. In the event of any such termination of the ESPP, the offering period and the purchase period will be deemed to have ended on the last trading day prior to such termination, and the options of each participant then outstanding will be deemed to be automatically exercised on such last trading day.

        The ESPP will terminate on the day before the 10th anniversary of the date of adoption of the ESPP by our board of directors, unless earlier terminated. Our compensation committee may amend, suspend, or terminate the ESPP; however, any such amendment, suspension, or termination may not impair any vested rights without the employee's consent. Our compensation committee may not increase the number of shares reserved for issuance under the ESPP without stockholder approval.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

        The following is a description of transactions since January 1, 2016 to which we have been or are to be a participant, in which the amount exceeds $120,000, and in which any of our directors, executive officers or beneficial owners of more than 5% of any class of our voting securities, or any immediate family member of or person sharing a household with any of the foregoing persons, had or will have a direct or indirect material interest, other than employment relationships with our executive officers and compensation to our directors. Employment relationships with and compensation paid to our NEOs are described under the section entitled "Executive Compensation" and compensation to our directors is described in "Management—Non-Employee Director Compensation."

Our Relationships with Yale University and Dr. Lieping Chen

Consulting Agreement with Lieping Chen, M.D., Ph.D.

        In December 2015, we entered into a consulting agreement for advisory services with our scientific founder, Dr. Lieping Chen, who beneficially owned more than 5% of our outstanding common stock at the time of the transaction. The term of the consulting agreement expires December 31, 2020. Under the agreement, Dr. Chen receives $5,000 per month in consulting fees until the expiration of the agreement.

Yale License Agreement and Sponsored Research Agreement

        In December 2015, we entered into a license agreement with Yale University, which beneficially owned more than 5% of our outstanding common stock at the time of the transaction. Under the Yale Agreement, we obtained a license to products that either incorporate certain licensed patents used in the discovery of targets or arise out of research and development of Dr. Chen's laboratory at Yale, including S15. We are obligated to pay Yale low single-digit royalties on sales of products, including NC318, that are either covered by the patents licensed to us under the Yale Agreement or arise out of Dr. Chen's laboratory, subject to minimum annual royalty payments in the low to mid hundreds of thousands of dollars. Until we are required to pay royalties under the Yale Agreement, we must pay an annual license maintenance fee to Yale in the mid to high tens of thousands of dollars. In addition, with respect to each product covered by licenses under the Yale Agreement, we are obligated to pay Yale milestone payments in an aggregate amount of up to approximately $3.0 million.

        In connection with the Yale Agreement, we also entered into the SRA with Yale, in which we agreed to provide an aggregate of up to $12.4 million to fund a research program aimed at discovering new targets for immunomedicines. The research program is under the direction and supervision of Dr. Chen.

        Dr. Chen is the United Technologies Corporation Professor in Cancer Research and Professor of Immunobiology, of Dermatology and of Medicine (Medical Oncology) at Yale, and the Co-Director of the Cancer Immunology Program at the Yale Cancer Center. For more information about the Yale Agreement and the SRA, see "Business—Our Collaboration Agreements—Agreements with Yale University."

Gift to Yale University

        In March 2016, we made a charitable contribution to Dr. Chen at Yale University of $500,000 to be used at Dr. Chen's discretion to support research activities.

Our Relationship with Eli Lilly

        In November 2018, we entered into the Lilly Agreement, which is focused on the discovery and development of immunomedicines for oncology using our FIND-IO platform. At the time of the transaction, Lilly beneficially owned more than 5% of our outstanding common stock. We received an upfront payment of $25.0 million in cash and an equity investment of $15.0 million from Lilly upon entering into the Lilly Agreement and are eligible for support, option exercise and milestone payments of

151

an aggregate of up to $1.4 billion, as well as mid to high single-digit royalties under the Lilly Agreement. Upon our exercise of an option with respect to a given target, we will owe Lilly option exercise, milestone and royalty payments in amounts equivalent to a portion of the amounts payable by Lilly were Lilly to exercise an option. For more information on the Lilly Agreement, see "Business—Our Collaboration Agreements—Research and Development Collaboration with Lilly."

Indemnification Agreements

These indemnification agreements also generally require us to advance any expenses incurred by the directors and executive officers as a result of any proceeding against them as to which they could be indemnified. For more information regarding these agreements, see "Management—Limitation on Liability and Indemnification Matters."

Policies and Procedures Regarding Transactions with Related Persons

        Our board of directors adopted a written related person transaction policy, effective upon the closing of the IPO, setting forth the policies and procedures for the review and approval or ratification of related person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships in which we were or are to be a participant, where the amount involved exceeds $120,000 and a related person had or will have a direct or indirect material interest. Types of transactions covered by this policy include, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person. In reviewing and approving any such transactions, our audit committee is tasked to consider all relevant facts and circumstances, including but not limited to whether the transaction is on terms comparable to those that could be obtained in an arm's length transaction with an unrelated third party and the extent of the related person's interest in the transaction.

PRINCIPAL STOCKHOLDERS

        The following table sets forth information relating to the beneficial ownership of our common stock as of October 28, 2019, by:

        The number of shares beneficially owned prior to this offering by each entity, person, director or executive officer is determined in accordance with SEC rules, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rules, beneficial ownership includes any shares over which the individual has sole or shared voting power or investment power as well as any shares that the individual has the right to acquire within 60 days of October 28, 2019 through the exercise of any stock option or other rights. Except as otherwise indicated, and subject to applicable community property laws, the persons named in the table have sole voting and investment power with respect to all shares of common stock held by that person.

        The percentage of shares beneficially owned is computed on the basis of 22,714,765 shares of our common stock outstanding on October 28, 2019. The percentage of beneficial ownership after this offering in the table below is based on            shares of common stock assumed to be outstanding after the closing of this offering, assuming no exercise of the underwriters' option to purchase additional shares. Shares of our common stock that a person has the right to acquire within 60 days of October 28, 2019 are deemed outstanding for purposes of computing the percentage ownership of the person holding such rights, but not for purposes of computing the percentage ownership of any other person, except with respect to the percentage ownership of all directors and executive officers as a group. Except as set forth below, the

DESCRIPTION OF CAPITAL STOCK

        The following summary describes our capital stock and the material provisions of our amended and restated certificate of incorporation and our amended and restated bylaws and of the Delaware General Corporation Law. Because the following is only a summary, it does not contain all of the information that may be important to you. For a complete description, you should refer to our amended and restated certificate of incorporation and amended and restated bylaws, copies of which have been filed as exhibits to the registration statement of which this prospectus is part.

General

        Our amended and restated certificate of incorporation authorizes 100,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of preferred stock, $0.001 par value per share, all of which shares of preferred stock are undesignated. Our board of directors may establish the rights and preferences of the preferred stock from time to time.

        As of June 30, 2019, there were outstanding:

Common Stock

Voting Rights

        Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the directors. In addition, the affirmative vote of holders of 66 2/3% of the voting power of all of the then outstanding voting stock will be required to take certain actions, including amending certain provisions of our amended and restated certificate of incorporation, such as the provisions relating to the classified board.

Dividends

        Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.

Liquidation

        In the event of our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.

Rights and Preferences

        Holders of our common stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of our preferred stock that we may designate in the future.

159

Pursuant to 17 C.F.R. Section 200.83

Fully Paid and Nonassessable

        All of our outstanding shares of common stock are, and the shares of common stock to be issued in this offering will be, fully paid and nonassessable.

Stock Options

        As of June 30, 2019, options to purchase 2,027,502 shares of our common stock were outstanding under the 2015 Plan, with a weighted average exercise price of $4.79 per share. No further awards will be made under the 2015 Plan. For additional information regarding the terms of the 2015 Plan, see "Executive Compensation—Equity Incentive Plans—2015 Omnibus Incentive Plan." As of June 30, 2019, options to purchase 210,275 shares of our common stock were outstanding under the 2019 Plan, with a weighted average exercise price of $15.57 per share, and 2,689,725 additional shares of our common stock remained available for future issuance thereunder. For additional information regarding the terms of the 2019 Plan, see "Executive Compensation—Equity Incentive Plans—2019 Omnibus Incentive Plan."

Preferred Stock

        Under the terms of our amended and restated certificate of incorporation, our board of directors has the authority, without further action by our stockholders, to issue up to 10,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting, or the designation of, such series, any or all of which may be greater than the rights of common stock. The issuance of our preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon our liquidation. In addition, the issuance of our preferred stock could have the effect of delaying, deferring or preventing a change in control of our company or other corporate action. No shares of preferred stock are currently outstanding, and we have no present plan to issue any shares of preferred stock.

Registration Rights

        Under the terms of our amended and restated investors' rights agreement, the holders of            shares of common stock, or their transferees, have the right to require us to register their shares, or the registrable shares, under the Securities Act so that those shares may be publicly resold, and the right to include their shares in any registration statement we file, in each case as described below.

Demand Registration Rights

        The holders of the registrable shares are entitled to certain demand registration rights. Beginning on November 8, 2019, the holders of at least 20% of these shares can, on not more than two occasions, request that we register all or a portion of their shares if the aggregate offering price of the shares would exceed $10 million (after deductions of underwriters' commissions and expenses).

Piggyback Registration Rights

        In the event that we determine to register any of our securities under the Securities Act (subject to certain exceptions), either for our own account or for the account of other security holders, the holders of the registrable shares will be entitled to certain "piggyback" registration rights allowing the holders to include their shares in such registration, subject to certain marketing and other limitations. As a result, whenever we propose to file a registration statement under the Securities Act, other than with respect to a registration related to employee benefit plans, registration on a form that does not include substantially the same information as would be required to be included in a registration statement covering the registrable shares, a registration in which the only common stock being registered is common stock issuable upon

160


Table of Contents

Pursuant to 17 C.F.R. Section 200.83

conversion of debt securities also being registered, or corporate reorganizations or certain other transactions, the holders of these shares are entitled to notice of the registration and have the right, subject to limitations that the underwriters may impose on the number of shares included in the registration, to include their shares in the registration. In an underwritten offering, the underwriters have the right, subject to specified conditions, to exclude or limit the number of shares such holders may include.

Form S-3 Registration Rights

        If we become and are eligible to file a registration statement on Form S-3, the holders of the registrable shares can make a written request that we register their shares on Form S-3 if we are eligible to file a registration statement on Form S-3 and if the aggregate offering price of the shares is at least $1 million (after deductions of underwriters' commissions and expenses). These stockholders may make an unlimited number of requests for registration on Form S-3, but in no event shall we be required to file more than two registrations on Form S-3 in any given 12-month period.

Expenses of Registration

        We will pay the registration expenses of the holders of the shares registered pursuant to the demand, piggyback and Form S-3 registration rights described above, including the reasonable expenses of one counsel for the selling holders.

Expiration of Registration Rights

        The demand, piggyback and Form S-3 registration rights described above will expire, with respect to any particular stockholder, upon the earlier of May 13, 2024 and when that stockholder can sell all of its shares under Rule 144 under the Securities Act without limitation during any three-month period without registration.

Anti-Takeover Effects of Provisions of Our Amended and Restated Certificate of Incorporation, Our Amended and Restated Bylaws and Delaware Law

        Certain provisions of Delaware law and our amended and restated certificate of incorporation and our amended and restated bylaws could make the following transactions more difficult: acquisition of us by means of a tender offer; acquisition of us by means of a proxy contest or otherwise; or removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions that might result in a premium over the market price for our shares.

        These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Delaware Anti-Takeover Statute

        We are subject to Section 203 of the Delaware General Corporation Law, which prohibits persons deemed "interested stockholders" from engaging in a "business combination" with a publicly traded Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an "interested stockholder" is a person who, together with affiliates and associates, owns, or within three

161


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

years prior to the determination of interested stockholder status did own, 15% or more of a corporation's voting stock. Generally, a "business combination" includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the board of directors, such as discouraging takeover attempts that might result in a premium over the market price of our common stock.

Undesignated Preferred Stock

        The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of our company.

Special Stockholder Meetings

        Our amended and restated bylaws provide that a special meeting of stockholders may be called only by our board of directors, our Chair, President or Chief Executive Officer.

Requirements for Advance Notification of Stockholder Nominations and Proposals

        Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors.

Elimination of Stockholder Action by Written Consent

        Our amended and restated certificate of incorporation and our amended and restated bylaws eliminate the right of stockholders to act by written consent without a meeting.

Classified Board; Election and Removal of Directors; Filling Vacancies; Board Size

        Our board of directors is divided into three classes. The directors in each class will serve for a three-year term, one class being elected each year by our stockholders, with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Because our stockholders do not have cumulative voting rights, our stockholders holding a majority of the shares of common stock outstanding will be able to elect all of our directors. Our amended and restated certificate of incorporation provides for the removal of any of our directors only for cause and requires a stockholder vote by the holders of at least a 66 2/3% of the voting power of the then outstanding voting stock. For more information on the classified board, see "Management—Classified Board of Directors." Any vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of the board, may only be filled by a resolution of the board of directors unless the board of directors determines that such vacancies shall be filled by the stockholders. Furthermore, the authorized number of directors may be changed only by a resolution of the board of directors. This system of electing and removing directors, filling vacancies and fixing the size of the board may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors.

Choice of Forum

        Our amended and restated bylaws provide that unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware or, if subject matter jurisdiction of such action is vested exclusively in the federal courts, the United States District Court for the District of Delaware will, to the

162


Table of Contents

Confidential Treatment Requested by NextCure, Inc.
Pursuant to 17 C.F.R. Section 200.83

fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers and employees, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, (iv) any action or proceeding to interpret, apply, enforce or determine the validity of our certificate of incorporation or the bylaws or (v) any action asserting a claim that is governed by the internal affairs doctrine, in each case subject to the Court of Chancery or the United States District Court for the District of Delaware, as applicable, having personal jurisdiction over the indispensable parties named as defendants therein. In addition, any person holding, owning or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and to have consented to this provision of our bylaws. The choice of forum provision does not apply to any actions arising under the Securities Act or the Exchange Act. Although our amended and restated bylaws contain the choice of forum provision described above, it is possible that a court could find that such a provision is inapplicable for a particular claim or action or that such provision is unenforceable.

Amendment of Charter Provisions

        The amendment of any of the above provisions that are in our amended and restated certificate of incorporation, except for the provision making it possible for our board of directors to issue undesignated preferred stock, would require approval by a stockholder vote by the holders of at least a 662/3% of the voting power of the then outstanding voting stock.

        The provisions of the Delaware General Corporation Law, our amended and restated certificate of incorporation and our amended and restated bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Limitation of Liability and Indemnification Matters

        For a discussion of liability and indemnification, see "Management—Limitation on Liability and Indemnification Matters."

Listing

        Our common stock is listed on the Nasdaq Global Select Market under the symbol "NXTC".

Transfer Agent and Registrar

        The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC. The transfer agent and registrar's address is 6201 15th Avenue, Brooklyn, New York 11219.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS OF COMMON STOCK

        The following is a summary of the material U.S. federal income tax consequences of the ownership and disposition of our common stock acquired in this offering by a Non-U.S. Holder (as defined below). For purposes of this discussion, a Non-U.S. Holder is a beneficial owner of our common stock that is not a "U.S. person" or partnership, including any entity or arrangement treated as a partnership and the equity holders therein, for U.S. federal income tax purposes.

        A U.S. person is any of the following:

        If you are an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and your activities. Partnerships holding our common stock and the partners in such partnerships are urged to consult their tax advisors as to particular U.S. federal income tax consequences to them of holding and disposing of our common stock.

        This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, possibly with retroactive effect. We have not sought and will not seek any rulings from the Internal Revenue Service, or IRS, regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the ownership and disposition of our common stock.

        This discussion is limited to Non-U.S. Holders who hold our common stock as a "capital asset" within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does consider any specific facts or circumstances that may be relevant to holders subject to special rules under the U.S. federal income tax laws, including, without limitation, certain former citizens or long-term residents of the United States, a person who holds or receives our common stock pursuant to the exercise of an employee stock option or otherwise as compensation, partnerships (or arrangements classified as partnerships for U.S. federal income tax purposes) or other pass-through entities and the equity holders therein, "controlled foreign corporations," "passive foreign investment companies," corporations that accumulate earnings to avoid U.S. federal income tax, banks, financial institutions, investment funds, insurance companies, brokers, dealers or traders in securities, tax-exempt organizations, tax-qualified retirement plans or foreign pension funds, persons subject to the alternative minimum tax, persons subject to special tax accounting rules under Section 451(b) of the Code, persons that own, or have owned, actually or constructively, more than 5% of our common stock and persons holding our common stock as part of a hedging or conversion transaction or straddle, or a constructive sale, or other risk reduction strategy.

        This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to you in light of your particular circumstances, and does not address the potential application of the alternative minimum tax, Medicare contribution tax, estate or gift taxes and does not address any aspect of

state, local or non-U.S. taxation, or any taxes other than income taxes. You should consult your tax adviser with regard to the application of the U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

        PROSPECTIVE INVESTORS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE PARTICULAR U.S. FEDERAL INCOME TAX CONSEQUENCES TO THEM OF ACQUIRING, OWNING AND DISPOSING OF OUR COMMON STOCK, AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER ANY STATE, LOCAL OR NON-U.S. TAX LAWS AND ANY OTHER U.S. FEDERAL TAX LAWS.

Distributions

        Distributions of cash or other property paid on our common stock will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed our current and accumulated earnings and profits, they will constitute a return of capital, which will first reduce your basis in our common stock, but not below zero, and any excess will be treated as gain from the sale or other disposition of our common stock, as described below under "—Gain on Disposition of Our Common Stock."

        Dividends paid to you generally will be subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty. In order to obtain a reduced rate of withholding, subject to the discussion below under "—FATCA," you will be required to provide to us or our paying agent a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E (or applicable successor form) certifying your entitlement to benefits under a treaty. This certification must be provided to us or our paying agent prior to the payment of dividends and must be updated periodically. If you hold our common stock through a financial institution or other agent acting on your behalf, you will be required to provide appropriate documentation to the agent, which then will be required to provide certification to us or our paying agent, either directly or through other intermediaries.

        If you do not timely provide the required certification, but qualify for a reduced treaty rate, you may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

        If dividends paid to you are effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base maintained by you in the United States), you will generally be taxed on the dividends on a net income basis in the same manner as a U.S. person. If you are a foreign corporation you also may be subject to an additional branch profits tax equal to 30% (or such lower rate specified by an applicable income tax treaty) of your effectively connected earnings and profits for the taxable year, as adjusted for certain items.

        If dividends paid to you are effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base maintained by you in the United States), you will be exempt from the withholding tax discussed in the preceding paragraph, although you will be required to provide a properly executed IRS Form W-8ECI in order to claim an exemption from withholding. You should consult your tax advisors regarding any applicable income tax treaties that may provide for different rules.

Gain on Disposition of Our Common Stock

        Subject to the discussions below under "—Information Reporting and Backup Withholding" and "—FATCA," you generally will not be subject to U.S. federal income or withholding tax on gain realized on a sale or other taxable disposition of our common stock unless:

        You will generally be taxed on the gain described in the first bullet above in the same manner as a U.S. person. If you are a foreign corporation, you also may be subject to an additional branch profits tax equal to 30% (or such lower rate specified by an applicable income tax treaty) of your effectively connected earnings and profits for the taxable year, as adjusted for certain items.

        You will generally be subject to U.S. federal income tax at a flat 30% rate (or such lower rate specified by an applicable income tax treaty) on gain described in the second bullet point above; however, such gain may be offset by certain U.S.-source capital losses (even though you are not considered a resident of the United States), provided that you have timely filed U.S. federal income tax returns with respect to such losses.

        Generally, a corporation is a USRPHC only if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus any of its assets used or held for use in a trade or business. Although there can be no assurance, we do not believe that we are, or have been, a UPRHC, or that we are likely to become one in the future. Even if we are a USRPHC, for so long as our common stock is regularly traded on an established securities market, sales of our common stock generally will not be subject to tax if you have not held more than 5% of our common stock, actually or constructively, during the five-year period preceding such sale or other disposition of our common stock (or your holding period, if shorter). If we are a USRPHC and either our common stock is not regularly traded on an established securities market or you hold, or are treated as holding, more than 5% of our outstanding common stock, directly or indirectly, during the applicable testing period, you will generally be taxed on any gain in the same manner as gain that is effectively connected with the conduct of a U.S. trade or business, except that the branch profits tax generally will not apply. No assurance can be provided that our common stock will continue to be regularly traded on an established securities market for purposes of the rules described above. You are encouraged to consult your own tax advisors regarding the possible consequences to you if we are, or were to become, a USRPHC.

Information Reporting and Backup Withholding

        Information returns are required to be filed with the IRS in connection with payments of dividends on our common stock. Unless you comply with certification procedures to establish that you are not a U.S. person, information returns may also be filed with the IRS in connection with the proceeds from a sale or other disposition of our common stock. You may be subject to backup withholding on payments on our common stock or on the proceeds from a sale or other disposition of our common stock unless the

166


Table of Contents

applicable withholding agent does not have actual knowledge or reason to know that you are a U.S. person and you comply with certification procedures to establish that you are not a U.S. person or otherwise establish an exemption. Your provision of a properly executed applicable IRS Form W-8 certifying your non-U.S. status will permit you to avoid backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know that you are a U.S. person. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

FATCA

        Provisions of the Code commonly referred to as the Foreign Account Tax Compliance Act, or FATCA, require withholding of 30% on payments of dividends on our common stock, and, subject to the discussion of certain proposed Treasury Regulations below, gross proceeds of dispositions of our common stock, to "foreign financial institutions" (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Under certain circumstances, you may be eligible for refunds or credits of such taxes. The U.S. Treasury recently released proposed Treasury Regulations which, if finalized in their present form, would eliminate the federal withholding tax of 30% applicable to the gross proceeds of a sale or other disposition of our common stock. In its preamble to such proposed Treasury Regulations, the U.S. Treasury stated that taxpayers may generally rely on the proposed regulations until final regulations are issued. You should consult your tax adviser regarding the effects of FATCA on your investment in our common stock.

        The underwriters are offering the shares of common stock subject to their acceptance of the shares from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of common stock offered by this prospectus are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of common stock offered by this prospectus if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters' option to purchase additional shares described below.

        The underwriters initially propose to offer part of the shares of common stock directly to the public at the offering price listed on the cover of this prospectus and part to certain dealers at a price that represents a concession not in excess of $            per share under the public offering price. After the initial offering of the shares of common stock, the offering price and other selling terms may from time to time be varied by the representatives.

        We have granted the underwriters an option for a period of 30 days from the date of this prospectus to purchase up to an additional            shares of our common stock. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of common stock as the number listed next to the underwriter's name in the preceding table bears to the total number of shares of common stock listed next to the names of all underwriters in the preceding table.

        The following table shows the per share and total public offering price, underwriting discounts and commissions and proceeds before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase up to an additional            shares of common stock.

        The underwriters have informed us that they do not intend sales to discretionary accounts to exceed 5% of the total number of shares of common stock offered by them.

        Our common stock is listed on the Nasdaq Global Select Market under the trading symbol "NXTC."

        We and all directors and officers and certain stockholders have agreed that, without the prior written consent of the representatives, on behalf of the underwriters, we and they will not, during the period ending 90 days after the date of this prospectus, or the restricted period:

whether any such transaction described above is to be settled by delivery of common stock or such other securities, in cash or otherwise. In addition, we and each such person agrees that, without the prior written consent of the representatives, on behalf of the underwriters, we or such other person will not, during the restricted period, make any demand for, or exercise any right with respect to, the registration of any shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock.

        The restrictions described in the immediately preceding paragraph to do not apply to:

        The representatives, in their joint discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time.

        In order to facilitate the offering of the common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a

short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the option. The underwriters can close out a covered short sale by exercising the option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the option. The underwriters may also sell shares in excess of the option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of the common stock above independent market levels or prevent or retard a decline in the market price of the common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

        We and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

        A prospectus in electronic format may be made available on websites maintained by one or more underwriters, or selling group members, if any, participating in this offering. The representatives may agree to allocate a number of shares of common stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters that may make Internet distributions on the same basis as other allocations.

        The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses.

        In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of NextCure, Inc.

Opinion on the Financial Statements

        We have audited the accompanying balance sheets of NextCure, Inc. (the "Company") as of December 31, 2018 and 2017, the related statements of operations and comprehensive loss, preferred stock and stockholders' equity and cash flows for the years then ended and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2018 and 2017, and the results of its operations and its cash flows for the years then ended in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

        These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

        We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

        Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ Ernst & Young LLP

We have served as the Company's auditor since 2017.

NOTES TO FINANCIAL STATEMENTS

1. Nature of the Business and Basis of Presentation

Organization

        NextCure, Inc. ("NextCure" or the "Company") was incorporated in Delaware in September 2015 and is headquartered in Beltsville, Maryland. The Company is a clinical-stage biopharmaceutical company committed to discovering and developing novel, first-in-class immunomedicines to treat cancer and other immune-related diseases by restoring normal immune function. Through its proprietary Functional, Integrated, NextCure Discovery in Immuno-Oncology ("FIND-IO") platform, the Company studies various immune cells in order to discover and understand targets and structural components of immune cells and their functional impact in order to develop immunomedicines. Since inception, the Company has devoted substantially all of its efforts and financial resources to organizing and staffing the Company, identifying business development opportunities, raising capital, securing intellectual property rights related to the Company's product candidates, building and optimizing the Company's manufacturing capabilities and conducting discovery, research and development activities for the Company's product candidates, discovery programs and its FIND-IO platform.

Risks and Uncertainties

        The Company is subject to risks common to early-stage companies in the biotechnology industry including, but not limited to: having a limited operating history and no products approved for commercial sale; having a history of significant losses; our need to obtain additional financing; dependence on its ability to advance its current and future product candidates through clinical trials, marketing approval and commercialization; the unproven approach to the discovery and development of product candidates based on the Company's FIND-IO platform; the lengthy and expensive nature and uncertain outcomes of the clinical development process; the lengthy, time-consuming and unpredictable nature of the regulatory approval process; the results of preclinical studies and early-stage clinical trials that may not be predictive of future results; dependence on its key personnel; its limited manufacturing experience as an organization and with its manufacturing facility; risks related to patent protection and our pending patent applications; dependence on third-party collaborators for the discovery, development and commercialization of current and future product candidates; and significant competition from other biotechnology and pharmaceutical companies. Pursuit of the Company's business efforts will require significant amounts of additional capital, adequate personnel, infrastructure and extensive compliance-reporting capabilities. Even if the Company's development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

Liquidity

        The Company expects that its operating losses and negative cash flows will continue for the foreseeable future. As of the issuance date of the financial statements for the year ended December 31, 2018, the Company expects that its cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements through at least two years from the issuance date of the financial statements. The future viability of the Company beyond that date is dependent on its ability to raise additional capital to finance its operations. On April 5, 2018, the Company issued 28,181,819 shares of Series A-3 Preferred Stock at an issuance price of $1.10 per share for cash proceeds of $31.0 million (Note 9). On November 5, 2018, the Company entered into a Series B Preferred Stock Purchase Agreement and issued 15,052,117 shares of Series B-1 Preferred Stock at an issuance price of $1.59 per share, 34,276,734 shares of Series B-2 Preferred Stock at an issuance price of $1.59 per share and 7,500,000

shares of Series B-3 Preferred Stock at an issuance price of $2.00 per share for aggregate cash proceeds of $93.4 million (Note 9).

        The Company plans to seek additional funding through public or private equity offerings, debt financings, marketing and distribution arrangements, other collaborations, strategic alliances and licensing arrangements. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into strategic alliances or other arrangements on favorable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company's stockholders. If the Company is unable to obtain funding, the Company could be required to delay, reduce or eliminate research and development programs, product portfolio expansion or future commercialization efforts, which could adversely affect its business prospects.

        Although management continues to pursue these funding plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company, if at all, to fund continuing operations past two years from the issuance date of these financial statements.

Basis of Presentation

        The accompanying financial statements include the accounts of the Company. The Company's financial statements have been prepared in accordance with United States generally accepted accounting principles ("GAAP"). Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification ("ASC") and Accounting Standards Update ("ASU") of the Financial Accounting Standards Board ("FASB").

Reverse Stock Split

        On May 3, 2019, the Company effected a 1-for-8.0338 reverse stock split of its outstanding common stock. The par value and authorized shares of common stock were not adjusted as a result of the reverse stock split. All of the share and per share information presented in the accompanying financial statements has been adjusted to reflect the reverse common stock split on a retroactive basis for all periods and as of all dates presented.

Use of Estimates

        The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, management evaluates its estimates, including those related to accrued expenses, revenue recognition, the valuation of equity-based compensation, including incentive stock options, common stock and restricted common stock, as well as income taxes. The Company bases its estimates on various assumptions that the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Segment and Geographic Information

        Operating segments are defined as components of an entity about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations as and manages its business in one operating segment operating exclusively in the United States.

2. Summary of Significant Accounting Policies

Cash and Cash Equivalents

        The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. The Company deposits its cash primarily in checking, sweep account and money market accounts.

Restricted Cash

        The Company is required to maintain cash collateral on deposit in a segregated money market bank account, as a condition of its Term Loan (Note 8) equal to the principal portion on a quarterly basis. The bank may restrict withdrawals or transfers by, or on behalf of, the Company. The required reserve totaled $460,000 as of December 31, 2018. This amount is presented as restricted cash on the accompanying balance sheet.

        The following table reconciles cash and cash equivalents and restricted cash per the balance sheet to the statement of cash flows (in thousands):

 
  December 31,  
 
  2018   2017  

Cash and cash equivalents

  $ 135,173   $ 8,427  

Restricted cash

    460     860  

Total

  $ 135,633   $ 9,287  

Concentration of Credit Risk

        Financial instruments that potentially expose the Company to concentrations of credit risk primarily consist of cash and cash equivalents. The Company maintains its cash and cash equivalents at one accredited financial institution in amounts that exceed federally insured limits. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

Fair Value of Financial Instruments

        ASC Topic 820, Fair Value Measurement ("ASC 820"), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company's own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier value hierarchy that distinguishes between the following:

        Level 1—Quoted market prices in active markets for identical assets or liabilities.

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Summary of Significant Accounting Policies (Continued)

        Level 2—Inputs other than Level 1 inputs that are either directly or indirectly observable, such as quoted market prices, interest rates and yield curves.

        Level 3—Unobservable inputs developed using estimates of assumptions developed by the Company, which reflect those that a market participant would use.

        To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair values requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized as Level 3. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Property and Equipment, Net

        Property and equipment are recorded at cost. Depreciation is computed over the estimated useful lives of the related assets using the straight-line method. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life or term of the lease. Upon retirement or disposal, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is recorded to general and administrative expenses in the accompanying statement of operations and comprehensive loss. Routine expenditures for maintenance and repairs are expensed as incurred.

        Estimated useful lives for property and equipment are as follows:

 
  Estimated Useful Life

Computers and peripherals

  3 years

Equipment

  5 years

Furniture and fixtures

  7 years

Leasehold improvements

  Lesser of estimated useful life or remaining lease term

Construction in Progress

        Construction in progress (Note 4) is carried at cost and consists of specifically identifiable direct and indirect development and construction costs. While under construction, costs of the property are included in construction in progress until the property is placed in service, at which time costs are transferred to the appropriate property and equipment account including, but not limited to, leasehold improvements or other such accounts.

Impairment of Long-Lived Assets

        The Company reviews the recoverability of its long-lived asset group when events or changes in circumstances occur that indicate that the carrying value of the asset group may not be recoverable. The assessment of possible impairment is based on the ability to recover the carrying value of the asset group from the expected future cash flows (undiscounted and without interest expense) of the related operations. If these cash flows are less than the carrying value of such asset group, an impairment loss for the difference between the estimated fair value and carrying value is recorded. There was no impairment loss recognized during the years ended December 31, 2018 or 2017.

2. Summary of Significant Accounting Policies (Continued)

Preferred Stock

        The Company's preferred stock is classified outside of stockholders' deficit because the shares contain deemed liquidation rights that are a contingent redemption feature not solely within the control of the Company.

Research and Development Costs

        Expenditures, including payroll, contractor expenses and supplies, for research and development of products are expensed as incurred. Development costs incurred by third parties are expensed as the contracted work is performed. Where contingent milestone payments are due to third parties under research and development arrangements, the milestone payment obligations are expensed when the milestone results are probable of being achieved.

Patent Costs

        All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses in the accompanying statement of operations and comprehensive loss.

Stock-Based Compensation

        The Company accounts for its stock-based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation ("ASC 718"). ASC 718 requires all share-based payments to employees, consultants and directors, including grants of incentive stock options, nonqualified stock options, restricted stock awards, unrestricted stock awards or restricted stock units to employees, consultants and directors of the Company, to be recognized as expense in the statement of operations and comprehensive loss based on their grant date fair values. The Company estimates the fair value of options granted using the Black-Scholes option pricing model ("Black-Scholes") for stock option grants to both employees and non-employees and the fair value of common stock to determine the fair value of restricted stock.

        The Company recognizes forfeitures as they occur as allowed by ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09").

        The Black-Scholes option pricing model requires inputs based on certain subjective assumptions, including (i) the expected stock price volatility, (ii) the expected term of the award, (iii) the risk-free interest rate and (iv) expected dividends. Due to the lack of a public market for the Company's common stock and lack of company-specific historical and implied volatility data, the Company has based its computation of expected volatility on the historical volatility of a representative group of public companies with similar characteristics to the Company, including stage of product development and life science industry focus. The historical volatility is calculated based on a period of time commensurate with expected term assumption. The Company uses the simplified method as prescribed by the SEC Staff Accounting Bulletin No. 107, Share-Based Payment, to calculate the expected term for options granted to employees as it does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. The expected term is applied to the stock option grant group as a whole, as the Company does not expect substantially different exercise or post-vesting termination behavior among its employee

population. For options granted to non-employees, the Company utilizes the simplified method also as the basis for the expected term assumption. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected term of the stock options. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on its common stock.

        There are significant judgments and estimates inherent in the determination of the fair value of the Company's common stock. These estimates and assumptions include a number of objective and subjective factors, including external market conditions, the prices at which the Company sold shares of preferred stock, the superior rights and preferences of securities senior to its common stock at the time of, and the likelihood of, achieving a liquidity event, such as an initial public offering or sale.

        The Company expenses the fair value of its share-based compensation awards on a straight-line basis over the requisite service period, which is generally the vesting period.

Income Taxes

        The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax base. Deferred tax assets and liabilities, which relate primarily to the carrying amount of the Company's property and equipment and its net operating loss carryforwards, are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax expense or benefit is the result of changes in the deferred tax assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets where, based upon the available evidence, the Company concludes that it is more-likely-than-not that the deferred tax assets will not be realized. In evaluating its ability to recover deferred tax assets, the Company considers all available positive and negative evidence, including its operating results, ongoing tax planning and forecasts of future taxable income on a jurisdiction-by-jurisdiction basis. Because of the uncertainty of the realization of deferred tax assets, the Company has recorded a full valuation allowance against its deferred tax assets.

        Reserves are provided for tax benefits for which realization is uncertain. Such benefits are only recognized when the underlying tax position is considered more-likely-than-not to be sustained on examination by a taxing authority, assuming they possess full knowledge of the position and facts. Interest and penalties related to uncertain tax positions are recognized in the provision of income taxes; however, the Company currently has no interest or penalties related to uncertain income tax benefits.

Revenue Recognition

        The Company has adopted ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of ASC 606, the Company performs the following five steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable

2. Summary of Significant Accounting Policies (Continued)

consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect consideration it is entitled to in exchange for the goods or services it transfers to the customer.

        The Company evaluates customer options for material rights or options to acquire additional goods or services for free or at a discount. If the customer options are determined to represent a material right, the material right is recognized as a separate performance obligation at the outset of the arrangement.

        Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the customer and are considered distinct when (i) the customer can benefit from the good or service on its own or together with other readily available resources and (ii) the promised good or service is separately identifiable from other promises in the contract. In assessing whether promised goods or services are distinct, the Company considers factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to develop the intellectual property on its own or whether the required expertise is readily available and whether the goods or services are integral or dependent to other goods or services in the contract.

        The Company estimates the transaction price based on the amount expected to be received for transferring the promised goods or services in the contract. Consideration generally may include fixed consideration or variable consideration. Should an arrangement include variable consideration, the Company will evaluate the amount of potential payments and the likelihood that the payments will be received. The Company will utilize either the most likely amount method or expected amount method to estimate the amount expected to be received based on which method best predicts the amount expected to be received. The amount of variable consideration which is included in the transaction price may be constrained and will be included in the transaction price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period.

        The Company's contracts may include development and regulatory milestone payments which would be assessed under the most likely amount method and constrained if it is probable that a significant revenue reversal would occur. Milestone payments that are not within the Company's control or the licensee's control, such as regulatory approvals, will not be considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company will re-evaluate the probability of achievement of such development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments would be recorded on a cumulative catch-up basis, which would affect collaboration revenues in the period of adjustment.

        For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

        The Company allocates the transaction price based on the estimated stand-alone selling price of each of the performance obligations. The Company must develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions to determine the stand-alone selling price for service obligations, which may include other comparable transactions, pricing considered in negotiating the transaction and the estimated costs. Additionally, in determining the standalone selling price for material rights, the Company

may reference comparable transactions, clinical trial success probabilities and estimates of option exercise likelihood. Variable consideration will be allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated are consistent with the amounts the Company would expect to receive for the satisfaction of each performance obligation.

        The consideration allocated to each performance obligation is recognized as revenue when control is transferred for the related goods or services. For performance obligations which consist of licenses and other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

        Upfront payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations under these arrangements. Amounts expected to be recognized as revenue within the 12 months following the balance sheet date are classified as current portion of deferred revenue in the accompanying consolidated balance sheets. Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion. Amounts are recorded as accounts receivable when the Company's right to consideration is unconditional.

Comprehensive Loss

        The Company did not have any other comprehensive income or loss for any of the periods presented and, therefore, comprehensive loss did not differ from net loss.

Net Loss per Share

        The Company calculates basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for participating securities. The Company considers its Series A Preferred Stock and Series B Preferred Stock to be participating securities because in the event a dividend is paid on common stock, the holders of Series A Preferred Stock and Series B Preferred Stock would be entitled to receive dividends on a basis consistent with the common stockholders. Under the two-class method, the net loss attributable to common stockholders is not allocated to the preferred stock as the holders of the preferred stock do not have a contractual obligation to share in losses.

        Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock.

Recently Adopted Accounting Pronouncements

        In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) ("ASU 2016-08"), which clarified the revenue recognition implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ("ASU 2016-10"), which clarified the revenue recognition

guidance regarding the identification of performance obligations and the licensing implementation. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ("ASU 2016-12"), which narrowly amended the revenue recognition guidance regarding collectability, noncash consideration, presentation of sales tax and transition. ASU No. 2016-08, ASU No. 2016-10 and ASU 2016-12 are effective during the same period as ASU No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which is effective for the Company for fiscal years beginning after December 15, 2018 and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company adopted ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2014-09 as of January 1, 2018 on a retrospective basis. There was no revenue in previous years and the adoption of ASC 606 did not have any impact on prior year financial statements.

        In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). ASU 2016-15 eliminates the diversity in practice related to the classification of certain cash receipts and payments for debt prepayment or extinguishment costs, the maturing of a zero-coupon bond, the settlement of contingent liabilities arising from a business combination, proceeds from insurance settlements, distributions from certain equity method investees and beneficial interests obtained in a financial asset securitization. ASU 2016-15 designates the appropriate cash flow classification, including requirements to allocate certain components of these cash receipts and payments among operating, investing and financing activities. The retrospective transition method, requiring adjustment to all comparative periods presented, is required unless it is impracticable for some of the amendments, in which case those amendments would be prospectively applied as of the earliest date practicable. ASU 2016-15 is effective for the Company for fiscal years beginning after December 15, 2018 and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company adopted ASU 2016-15 as of January 1, 2018.

        In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18'), which requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning and ending balances shown on the statement of cash flows. The guidance is effective for the Company for fiscal years beginning after December 15, 2018 and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company adopted ASU 2016-18 as of January 1, 2017.

        In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09"), which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions of the agreement. The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company adopted ASU 2017-09 as of the required effective date of January 1, 2018. In June 2018, the FASB issued ASU No. 2018-07 Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ("ASU No. 2018-07"). ASU No. 2018-07 expands the guidance in ASC718 to include share-based payments for goods and services to non-employees and generally aligns it with the guidance for share-based payments to employees. The amendments are effective for the Company for fiscal years beginning after December 15, 2019 and interim periods within

fiscal years beginning after December 15, 2020, with early adoption permitted for entities that have adopted ASC 606. The Company adopted this new standard on January 1, 2018.

Recently Issued Accounting Pronouncements

        In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU 2016-02"). The new guidance requires lessees to record most leases on their balance sheets and recognize the related expenses on their income statements in a manner similar to current practice. ASU 2016-02 states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The standard is effective for the Company for fiscal years beginning after December 15, 2019 and interim periods fiscal years beginning after December 15, 2020. Early adoption is permitted. The Company is currently evaluating the effect of this standard on its financial statements.

6. Agreement with Eli Lilly and Company

        On November 2, 2018, the Company entered into a multi-year research and development collaboration agreement (the "Lilly Agreement") with Eli Lilly and Company ("Lilly"), pursuant to which the Company will use its proprietary FIND-IO platform to identify novel oncology targets for additional collaborative research and drug discovery by the Company and Lilly. Under the Lilly Agreement, Lilly and the Company have granted one another an equal number of exclusive options to research, develop, manufacture and commercialize compounds and products directed to oncology targets identified through the Lilly Agreement. Both Lilly and the Company each have all options remaining eligible for exercise. The research collaboration with Lilly will be managed by a joint steering committee formed by an equal number of members from the Company and Lilly and will expire upon the earlier of the exercise of all options granted to Lilly or four years from the date of the agreement, subject to certain extensions.

6. Agreement with Eli Lilly and Company (Continued)

        During the research term under the Lilly Agreement, as a part of target discovery, the Company will be responsible for providing Lilly with oncology targets identified using the Company's FIND-IO platform. From the targets provided by the Company, Lilly may select targets to advance to target validation using criteria developed by both parties. Following completion of the agreed upon target validation plan with respect to a given target, either party may propose to advance that target to compound discovery. For each target that has been advanced to compound discovery, Lilly will have the option to obtain an exclusive license with respect to the compounds and products directed to the target. If Lilly does not exercise its option with respect to a given target or has previously exercised all of its options, the Company will have the option to obtain licenses with respect to compounds and products directed to that target. Following option exercise by a party, the development and commercialization of any products directed to the target will be conducted by the exercising party. The exercising party must use commercially reasonable efforts to develop, seek regulatory approval for and commercialize any such products under mutually agreed upon work plans.

        The Company received an upfront, non-refundable payment of $25.0 million under the Lilly Agreement and a concurrent $15.0 million equity investment (Note 9). In addition, the Company will receive quarterly research and development support payments during a portion of the research term as well as option exercise fees upon option exercises by Lilly.

        Pursuant to the Lilly Agreement, Lilly will owe an aggregate of up to $1.4 billion in development and regulatory milestones and sales milestones. Additionally, Lilly will pay mid to high single-digit royalties on net sales for all products directed to each target optioned by Lilly. Upon the Company's exercise of an option with respect to a given target, the Company will pay Lilly option exercise, milestone and royalty payments. The company will owe an aggregate of up to $710.0 million in development and regulatory milestones and sales milestones.

        The company has evaluated the Lilly Agreement under ASC 606. Two performance obligations were identified as follows:

        The Lilly Agreement was executed in November 2018, however, the performance obligations were initiated in January 2019; accordingly no revenue was recorded under the Lilly Agreement in 2018. As of December 31, 2018, deferred revenue included in the Company's balance sheets in connection with the Lilly Agreement was $26.7 million, which consisted of the $25.0 million upfront payment plus $1.7 million attributed as a premium on the proceeds from Lilly's equity investment in the Company (Note 9).

Operating Leases

        The Company subleases its facilities under a non-cancelable operating sublease agreement. The sublease commenced on February 9, 2016 and expires on August 31, 2025. The Company is also responsible for its prorated share of the sublandlord's operating expense.

        Rent expense incurred under operating leases was approximately $420,000 and $376,000 for the years ended December 31, 2018 and 2017, respectively.

Contingencies

        The Company is subject to claims and assessments from time to time in the ordinary course of business. The Company records a provision for a liability when it believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount.

        In the normal course of business, the Company may become involved in legal proceedings. The Company will accrue a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. As of December 31, 2018 and 2017, the Company was not involved in any material legal proceedings.

8. Term Loan

        In April 2016, the Company entered into a $1.0 million term loan (the "Term Loan"). The Term Loan bears interest at the prime rate less 1%. The interest rate in effect was 4.5% and 3.5% for the years ended December 31, 2018 and 2017, respectively. The Term Loan is secured by all certificates of deposit, money market accounts, cash, securities, investment property and deposit or investment accounts. The Term Loan requires monthly payments of interest only before May 2017, and equal monthly payments of principal and interest thereafter, as defined in the agreement. Interest expense under the Term Loan was approximately $25,000 and $30,000 for the years ended December 31, 2018 and 2017, respectively. The outstanding balance on the Term Loan totaled $460,000 as of December 31, 2018.

9. Preferred Stock

        As of December 31, 2018, the Company's certificate of incorporation, as amended and restated, authorized the Company to issue 125,010,671 shares of $0.001 par value preferred stock. The Company's preferred stock is classified outside of stockholders' deficit because the shares contain deemed liquidation rights that are a contingent redemption feature not solely within the control of the Company.

Series A Preferred Stock

        As of December 31, 2018, the Company has issued 68,181,819 shares of Series A Preferred Stock as follows:

        In December 2015, the Company issued 15,000,000 shares of Series A-1 Preferred Stock at an issuance price of $1.00 per share for cash proceeds of $15.0 million.

        In January 2017, the Company issued 25,000,000 shares of Series A-2 Preferred Stock at an issuance price of $1.00 per share for cash proceeds of $25.0 million.

        In April 2018, the Company issued 28,181,819 shares of Series A-3 Preferred Stock at an issuance price of $1.10 per share for cash proceeds of approximately $31.0 million.

Series B Preferred Stock

        As of December 31, 2018, the Company has issued 56,828,851 shares of Series B Preferred Stock as follows:

        In November 2018, the Company issued 15,052,117 and 34,276,734 shares of Series B-1 Preferred Stock and Series B-2 Preferred Stock, respectively, at an issuance price of $1.59 per share for aggregate cash proceeds of approximately $78.4 million.

        Concurrent with the issuance of the Series B-1 Preferred Stock and Series B-2 Preferred Stock, in November 2018, the Company issued 7,500,000 shares of Series B-3 Preferred Stock at an issuance price of $2.00 per share for cash proceeds of $15.0 million in connection with the execution of the Collaboration Agreement with Lilly. The Company allocated $13.3 million of the proceeds to Series B-3 Preferred Stock and $1.7 million to deferred revenue. The $1.7 million was determined to be a premium over the fair value of the Series B-3 Preferred Stock and attributed as additional consideration of the Collaboration Agreement (Note 6).

        The Company estimated the premium of the Series B-3 Preferred Stock based on a valuation of the Company's preferred stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The $1.7 million premium on the Series B-3 Preferred Stock will be recognized as revenue on a proportional performance basis over the term of the Collaboration Agreement.

        The Company's Preferred Stock has the following rights and preferences, privileges and restrictions:

Dividends

        The holders of Preferred Stock are entitled to receive annual noncumulative dividends at an annual rate of 8% in preference to any declaration or payment of any dividend on the common stock, on an

as-converted basis when, as and if declared by the Board of Directors. As of December 31, 2018, no dividends have been declared.

Voting Rights

        Each share of Preferred Stock represents such number of votes as is equal to the number of shares of common stock into which such share is convertible. The holders of Preferred Stock vote together with the holders of common stock on an as-converted basis on all matters in which stockholders are entitled to vote. The holders of Series A Preferred Stock, exclusively and as a separate class, are entitled to elect five directors, the holders of the Series B Preferred Stock, exclusively and as a separate class, are entitled to elect two directors of the Company as of December 31, 2018.

Conversion Rights

        The holders of the Preferred Stock are entitled to convert each share into 0.1245 shares of common stock on demand. The Preferred Stock is mandatorily convertible upon the closing of a qualified public offering in which gross proceeds to the Company of not less than $75.0 million or on the date specified by a majority vote of the outstanding shares of Preferred Stock voting on an as-converted basis.

Liquidation Preference

        In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company, the holders of the Company's Series B Preferred Stock are entitled to receive, before any payment of any of the assets of the Company to the holders of the Series A Preferred Stock and holders of common stock, $12.77 per share with respect to shares of Series B-1 Preferred Stock and Series B-2 Preferred Stock and $16.07 per share with respect to shares of Series B-3 Preferred Stock (as adjusted for any stock dividend, stock split, combination or other similar transactions, plus any declared but unpaid dividends). After payment of the above but before any payment of any of the assets of the Company to the holders of common stock, the holders of Series A Preferred Stock are entitled to receive $8.03 per share with respect to shares of Series A-1 Preferred Stock and Series A-2 Preferred Stock and $8.84 per share with respect to shares of Series A-3 Preferred Stock (as adjusted for any stock dividend, stock split, combination or other similar transactions, plus any declared but unpaid dividends).

10. Common Stock

        As of December 31, 2018, the Company's Certificate of Incorporation, as amended and restated, authorized the Company to issue 158,745,671 shares of $0.001 par value common stock, of which 1,374,812 were issued and outstanding.

        Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company's stockholders. Common stockholders are entitled to receive dividends, as may be declared by the board of directors, if any, subject to the preferential dividend rights of the preferred stock. When dividends are declared on shares of common stock, the Company must declare at the same time a dividend payable to the holders of preferred stock equivalent to the dividend amount they would receive if each share of preferred stock was converted into common stock. The Company may not pay dividends to common stockholders until all dividends accrued or declared but unpaid on the preferred stock have been paid in full. No dividends have been declared or paid by the Company through December 31, 2018.

11. Stock-Based Compensation

2015 Omnibus Incentive Plan

        The NextCure, Inc. 2015 Omnibus Incentive Plan (the "2015 Plan") provides for the Company to grant incentive stock options or nonqualified stock options, restricted stock awards, unrestricted stock awards or restricted stock units to employees, consultants and directors of the Company. The 2015 Plan is administered by the board of directors, or at the discretion of the board of directors, by a committee of the board of directors. The exercise prices, vesting and other restrictions are determined at the discretion of the board of directors or its committee if so delegated, except that the exercise price per share of the stock options may not be less than 100% of the fair market value of a share of the Company's common stock on the date of grant and the term of the stock options may not be greater than 10 years.

        Under the 2015 Plan, the Company had initially reserved on December 29, 2015, 311,185 shares of common stock, which number of shares was automatically increased pursuant to the terms of the 2015 Plan by 373,422 as of the second closing of the Series A Preferred Stock financing on January 24, 2017. The total number of shares of common stock that may be issued under the 2015 Plan was 2,824,317 as of December 31, 2018. As of December 31, 2018, there were 2,056,891 stock options and 62,237 shares of registered stock outstanding and 699,590 shares of common stock available for future issuance under the 2015 Plan.

        Stock options granted under the 2015 Plan generally vest over four years and expire after 10 years.

        The exercise price for stock options granted is not less than the fair value of common shares as determined by the board of directors as of the date of grant. The board of directors determines the value the Company's common stock taking into consideration the most recently available third-party valuation of common shares, as well as additional factors, which may have changed since the date of the most recent contemporaneous valuation through the date of grant.

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the estimated fair value of the common stock for the options that were in the money at December 31, 2018 and 2017.

        The weighted average grant date fair value per share of stock options granted during the years ended December 31, 2018 and 2017 was $3.80 and $0.80, respectively. The aggregate intrinsic value of stock options exercised during the years ended December 31, 2018 and 2017 was $38,000 and $0, respectively.

        The aggregate grant date fair value of stock options and restricted stock vested during the year ended December 31, 2018 and 2017 was approximately $157,000 and $29,000, respectively.

Stock-Based Compensation

        The Company recorded stock-based compensation expense of $263,000 and $75,000 during the years ended December 31, 2018 and 2017, respectively. As of December 31, 2018, there was $6.0 million of unrecognized compensation cost related to unvested stock-based compensation arrangements granted under the 2015 Plan. This remaining compensation expense is expected to be recognized over a weighted average period of three years as of December 31, 2018.

        Stock-based compensation expense recorded as research and development and general and administrative expenses is as follows (in thousands):

Restricted Common Stock

        In May 2016, the Company issued 62,237 shares of restricted common stock from the 2015 Plan, which are restricted as to sale or transferability. These restrictions lapse over a four-year period.

12. Net Loss Per Share Attributable to Common Stockholders

        The following table summarizes the computation of basic and diluted net loss per share attributable to common stockholders of the Company (in thousands, except share and per share amounts):

        The Company's potential dilutive securities, which include preferred stock and common stock options, have been excluded from the computation of diluted net loss per share as the effect would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at period end, from the computation of diluted net loss per share attributable to common stockholders for the period indicated because including them would have had an anti-dilutive effect:

13. Income Taxes

2017 U.S. Tax Reform

        On December 22, 2017, the U.S. government signed into law the Tax Cuts and Jobs Act (the "Tax Act") that significantly reforms the Internal Revenue Code of 1986, as amended. The Tax Act, among other things, contains significant changes to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, effective as of January 1, 2018; limitation of the tax deduction for interest expense; limitation of the deduction for net operating losses to 80% of annual taxable income and elimination of net operating loss carrybacks, in each case, for losses arising in taxable years beginning after December 31, 2017 (though any such tax losses may be carried forward indefinitely); and modifying or repealing many business deductions and credits, including reducing the business tax credit for certain clinical testing expenses incurred in the testing of certain drugs for rare diseases or conditions generally referred to as "orphan drugs".

        In 2018, the Company finished its analysis of the impact of the Tax Act. Where the Company made reasonable estimates in 2017 of the effects related to the Tax Act, the Company recorded provisional amounts. After the completed analysis, the resulting impact to the Company's financial statements did not differ from the recorded provisional amounts.

Income Taxes

        The reconciliation of federal statutory income tax rate to the Company's effective income tax rate is as follows:

 
  December 31,  
 
  2018   2017  

Expected income tax benefit at the federal statutory rate

    21.0 %   34.0 %

State taxes, net of federal benefit

Prior year provision to return adjustments

Tax rate reduction due to the Tax Act

        (15.6 )

Other

    0.3     (2.9 )

Change in valuation allowance

    (25.1 )   (25.5 )

        Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Net deferred tax assets

  $   $  

        Based on the Company's history of losses, the Company recorded a full valuation allowance against its deferred tax assets as of December 31, 2018. The Company increased its valuation allowance by approximately $8.0 million for the year ended December 31, 2018. The Company intends to maintain a valuation allowance until sufficient positive evidence exists to support a reversal of the allowance.

        As of December 31, 2018, the Company had federal and state net operating loss carryforwards of $43.5 million and $43.0 million, respectively, some of which begin to expire in the year ending December 31, 2036. Approximately $20.8 million of the federal and state net operating loss carryforwards do not expire. The Company had federal and state research and development tax credit carryforwards of approximately $2.5 million and $1.1 million, respectively, as of December 31, 2018. The federal credits begin to expire in the year ending December 31, 2036 and the state credits begin to expire in the year ending December 31, 2024.

        Under the provisions of Sections 382 and 383 of the Internal Revenue Code (the "IRC"), net operating loss and credit carryforwards and other tax attributes may be subject to limitation if there has been a significant change in ownership of the Company, as defined by the IRC. Future owner or equity shifts, including an initial public offering, could result in limitations on net operating loss and credit carryforwards.

        The Company files income tax returns in the U.S. federal jurisdiction as well as in Maryland. The tax years 2015 to 2017 remain open to examination by the major jurisdictions in which the Company are subject to tax. Fiscal years outside the normal statute of limitation remain open to audit by tax authorities due to tax attributes generated in those early years, which have been carried forward and may be audited in subsequent years when utilized.

13. Income Taxes (Continued)

        The Company evaluates tax positions for recognition using a more-likely-than-not recognition threshold, and those tax positions eligible for recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon the effective settlement with a taxing authority that has full knowledge of all relevant information. As of December 31, 2018, the Company had no unrecognized income tax benefits that would affect the Company's effective tax rate if recognized.

14. Employee Benefit Plan

        The Company sponsors a 401(k) plan that stipulates that eligible employees can elect to contribute to the 401(k) plan, subject to certain limitations, up to the lesser of the statutory maximum or 100% of eligible compensation on a pre-tax basis. Through December 31, 2018, the Company has not provided any contributions to this plan.

15. Related Party Transactions

Lilly Agreement

        In November 2018, the Company entered into the Lilly Agreement with a stockholder of the Company, Lilly, pursuant to which the Company will use its proprietary FIND-IO platform to identify novel oncology targets for additional collaborative research and drug discovery by the Company and Lilly. Lilly provided to the Company a cash upfront payment of $25.0 million upon entering into the Collaboration Agreement and made a concurrent $15.0 million equity investment in the Company (Note 6 and Note 9).

Consulting Agreement with Scientific Founder

        In December 2015, the Company entered into a consulting agreement for scientific advisory services with a founder of the Company (the "Scientific Founder"), who is also a stockholder of the Company. The term of the consulting agreement expires December 31, 2020. Under the agreement, the Scientific Founder is entitled to receive $5,000 per month in consulting fees until the expiration of the agreement. As of December 31, 2018, the amount due under this agreement is $120,000.

Yale License Agreement and Sponsored Research Agreement

        In December 2015, the Company entered into a license agreement with Yale University (the "Yale Agreement"), which is also a stockholder of the Company. Under the Yale Agreement, the Company obtained a license to products that either incorporate certain licensed patents used in the discovery of targets or arise out of research and development of the Scientific Founder's laboratory at Yale, including a proprietary target. The Company is obligated to pay Yale low single-digit royalties on sales of products that are either covered by the patents licensed to the Company under the Yale Agreement or arise out of the Scientific Founder's laboratory, subject to minimum annual royalty payments in the low to mid hundreds of thousands of dollars, an annual license maintenance fee in the mid to high tens of thousands of dollars and milestone payments of up to $3.0 million per product.

        In connection with the Yale Agreement, the Company also entered into the Corporate Sponsored Research Agreement with Yale (the "SRA"), in which the Company agreed to provide an aggregate of up to $12.4 million to fund a research program aimed at discovering new targets for immunomedicines. The research program is under the direction and supervision of the Scientific Founder. As of December 31,

2018, the Company has made payments in an aggregate of $7.4 million under the SRA, including $2.5 million and $2.1 million in the years ended December 31, 2018 and 2017, respectively.

16. Subsequent Events

        On January 25, 2019, the Company amended its Term Loan to an aggregate principal amount of $5.0 million, which remains secured by the Company's certificates of deposit, money market account, investment property and deposit or investment accounts. As amended, the Term Loan bears interest at the greater of the prime rate less 1% and 4.25%. Under the agreement, the Company is required to make monthly interest-only payments through January 2020 and is required to make 36 equal monthly payments of principal plus accrued interest thereafter through January 2023.

        On January 30, 2019, the Company entered into a new lease for 14,075 square feet to be used for office, manufacturing and laboratory space, which the Company expects to take possession of in June 2019. The new lease is expected to expire in March 2030 and will also cover the Company's existing space after expiration of the Company's current lease. Base rent for the first 10 months is abated, after which the base rent of the lease is $19,650 per month, with an increase in annual rent of 3.0% in each subsequent year of the lease term.

        On March 15, 2019, the Company entered into an amended and restated lease that covers the Company's existing space plus additional square footage to be used as office space, which the Company took possession of upon entering into the amended and restated lease. The amended and restated lease expires in August 2025. The total remaining commitment under the amended and restated lease is approximately $3.0 million.

        On May 3, 2019, the Company effected a 1-for-8.0338 reverse stock split of its outstanding common stock. The par value and authorized shares of common stock were not adjusted as a result of the reverse stock split. All of the share and per share information presented in the accompanying financial statements has been adjusted to reflect the reverse common stock split on a retroactive basis for all periods and as of all dates presented.

1. Nature of the Business

Organization

        NextCure, Inc. ("NextCure" or the "Company") was incorporated in Delaware in September 2015 and is headquartered in Beltsville, Maryland. The Company is a clinical-stage biopharmaceutical company committed to discovering and developing novel, first-in-class immunomedicines to treat cancer and other immune-related diseases by restoring normal immune function. Through its proprietary Functional, Integrated, NextCure Discovery in Immuno-Oncology ("FIND-IO") platform, the Company studies various immune cells in order to discover and understand targets and structural components of immune cells and their functional impact in order to develop immunomedicines. Since inception, the Company has devoted substantially all of its efforts and financial resources to organizing and staffing the Company, identifying business development opportunities, raising capital, securing intellectual property rights related to the Company's product candidates, building and optimizing the Company's manufacturing capabilities and conducting discovery, research and development activities for the Company's product candidates, discovery programs and its FIND-IO platform.

Initial Public Offering

        On May 13, 2019, the Company closed its initial public offering ("IPO"), in which the Company issued and sold 5,750,000 shares of common stock at a public offering price of $15.00 per share, for net proceeds to the Company of approximately $77.0 million after deducting underwriting discounts and commissions of $6.0 million and offering expenses of approximately $3.4 million.

        In preparation for the IPO, on May 3, 2019, the Company effected a one-for-8.0338 reverse stock split of its issued and outstanding common stock. The par value and authorized shares of common stock were not adjusted as a result of the reverse stock split. All of the share and per share information presented in the accompanying financial statements has been adjusted to reflect the reverse common stock split on a retroactive basis for all periods and as of all dates presented.

        Upon the closing of the IPO, on May 13, 2019, all of the outstanding shares of the Company's convertible preferred stock automatically converted into 15,560,569 shares of common stock at the applicable conversion ratio then in effect. Subsequent to the closing of the IPO, there were no shares of preferred stock outstanding.

        Upon the closing of the IPO, on May 13, 2019, the Company's certificate of incorporation was amended and restated to provide for 100,000,000 authorized shares of common stock with a par value of $0.001 per share and 10,000,000 authorized shares of preferred stock with a par value of $0.001 per share.

Liquidity

        The Company has not generated any revenue to date from product sales and does not expect to generate any revenues from product sales in the foreseeable future. Through June 2019, the Company has funded its operations primarily with proceeds from the sale of preferred stock and proceeds from the Company's agreement with Eli Lilly and Company (Note 5) and proceeds from the IPO. The Company expects to incur additional operating losses and negative operating cash flows for the foreseeable future.

2. Summary of Significant Accounting Policies (Continued)

accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these condensed financial statements should be read in conjunction with the Company's audited financial statements and the notes thereto as of and for the year ended December 31, 2018, which are included in the Company's final prospectus that forms a part of the Company's Registration Statement on Form S-1 (Reg. No. 333-230837) (the "Registration Statement"), as filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, on May 9, 2019.

        The unaudited interim condensed financial statements have been prepared on the same basis as the audited financial statements. In the opinion of management, the accompanying unaudited interim condensed financial statements contain all adjustments necessary for a fair statement of the Company's financial position as of June 30, 2019 and condensed results of operations and cash flows for the three and six months ended June 30, 2019 and 2018. Such adjustments are of a normal and recurring nature. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2019.

Use of Estimates

        The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, management evaluates its estimates, including those related to accrued expenses, revenue recognition, the valuation of equity-based compensation, including incentive stock options, common stock and restricted common stock, as well as income taxes. The Company bases its estimates on various assumptions that the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Restricted Cash

        The Company is required, as a condition of its Term Loan (Note 7), to maintain cash collateral on deposit in a segregated money market bank account equal to the principal portion of the Term Loan, as determined on a quarterly basis. The bank may restrict withdrawals or transfers by or on behalf of the Company that would violate this requirement. The required reserve totaled $5.0 million as of June 30, 2019. This amount is presented as restricted cash on the accompanying balance sheet.

        The following table reconciles cash and cash equivalents and restricted cash per the balance sheet to the statement of cash flows (in thousands):

2. Summary of Significant Accounting Policies (Continued)

Revenue Recognition

        The Company has adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606"). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of ASC 606, the Company performs the following five steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect consideration to which it is entitled in exchange for the goods or services it transfers to the customer.

        The Company evaluates customer options for material rights or options to acquire additional goods or services for free or at a discount. If the customer options are determined to represent a material right, the material right is recognized as a separate performance obligation at the outset of the arrangement.

        Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the customer and are considered distinct when (i) the customer can benefit from the good or service on its own or together with other readily available resources and (ii) the promised good or service is separately identifiable from other promises in the contract. In assessing whether promised goods or services are distinct, the Company considers factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to develop the intellectual property on its own or whether the required expertise is readily available and whether the goods or services are integral to or dependent on other goods or services in the contract.

        The Company estimates the transaction price based on the amount expected to be received for transferring the promised goods or services in the contract. Consideration generally may include fixed consideration or variable consideration. Should an arrangement include variable consideration, the Company will evaluate the amount of potential payments and the likelihood that the payments will be received. The Company will utilize either the most likely amount method or expected amount method to estimate the amount expected to be received based on which method best predicts the amount expected to be received. The amount of variable consideration that is included in the transaction price may be constrained and will be included in the transaction price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period.

        The Company's contracts may include development and regulatory milestone payments which would be assessed under the most likely amount method and constrained if it is probable that a significant revenue reversal would occur. Milestone payments that are not within the Company's control or the licensee's control, such as regulatory approvals, will not be considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company re-evaluates the probability of achievement of such development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments would be recorded on a cumulative catch-up basis, which would affect collaboration revenues in the period of adjustment.

        For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company

will recognize revenue at the later of (i) when the related sales occur and (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

        The Company allocates the transaction price based on the estimated stand-alone selling price of each of the performance obligations. The Company must develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions to determine the stand-alone selling price for service obligations, which may include other comparable transactions, pricing considered in negotiating the transaction and the estimated costs. Additionally, in determining the standalone selling price for material rights, the Company may reference comparable transactions, clinical trial success probabilities and estimates of option exercise likelihood. Variable consideration will be allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated are consistent with the amounts the Company would expect to receive for the satisfaction of each performance obligation.

        The consideration allocated to each performance obligation is recognized as revenue when control is transferred for the related goods or services. For performance obligations which consist of licenses and other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

        Upfront payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations under these arrangements. Amounts expected to be recognized as revenue within the 12 months following the balance sheet date are classified as current portion of deferred revenue in the accompanying condensed balance sheets. Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion. Amounts are recorded as accounts receivable when the Company's right to consideration is unconditional.

Recently Issued Accounting Pronouncements

        The Company qualifies as an emerging growth company ("EGC") as defined under the Jumpstart Our Business Startups Act (the "JOBS Act"). Using exemptions provided under the JOBS Act provided to EGCs, the Company has elected to defer compliance with new or revised financial accounting standards until it is required to comply with such standards.

        In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU 2016-02"). The new guidance requires lessees to record most leases on their balance sheets and recognize the related expenses on their income statements in a manner similar to current practice. ASU 2016-02 states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The standard is effective for the Company January 1, 2020. Early adoption is permitted. The Company is currently evaluating the effect of this standard on its financial statements.

        In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. The amendment clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account.

2. Summary of Significant Accounting Policies (Continued)

In those situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation and disclosure requirements. The amendment also adds unit of account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606. Lastly, the amendment requires that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently evaluating these clarifications in the accounting and presentation for its collaborative arrangements within the scope of Topic 808 but does not expect it will have any impact.

3. Fair Value of Financial Instruments

        The Company has certain financial assets recorded at fair value, which have been classified as Level 1, 2 or 3 within the fair value hierarchy as described in the accounting standards for fair value measurements.

        Level 1—Quoted market prices in active markets for identical assets or liabilities.

        Level 2—Inputs other than Level 1 inputs that are either directly or indirectly observable, such as quoted market prices, interest rates and yield curves.

        Level 3—Unobservable inputs developed using estimates of assumptions developed by the Company, which reflect those that a market participant would use.

        To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair values requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized as Level 3. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

        The following tables set forth the fair value of the Company's financial assets by level within the fair value hierarchy (in thousands):

5. Agreement with Eli Lilly and Company

        On November 2, 2018, the Company entered into a multi-year research and development collaboration agreement (the "Lilly Agreement") with Eli Lilly and Company ("Lilly"), pursuant to which the Company will use its proprietary FIND-IO platform to identify novel oncology targets for additional collaborative research and drug discovery by the Company and Lilly. Under the Lilly Agreement, Lilly and the Company have granted one another an equal number of exclusive options to research, develop, manufacture and commercialize compounds and products directed to oncology targets identified through the Lilly Agreement. Both Lilly and the Company have all options remaining eligible for exercise. The research collaboration with Lilly will be managed by a joint steering committee formed by an equal number of members from the Company and Lilly and will expire upon the earlier of the exercise of all options granted to Lilly or four years from the date of the agreement, subject to certain extensions. The Company considers Lilly to be a related party based on Lilly's equity investment in the Company as discussed below.

5. Agreement with Eli Lilly and Company (Continued)

        During the research term under the Lilly Agreement, as a part of target discovery, the Company will be responsible for providing Lilly with oncology targets identified using the Company's FIND-IO platform. From the targets provided by the Company, Lilly may select targets to advance to target validation using criteria developed by both parties. Following completion of the agreed upon target validation plan with respect to a given target, either party may propose to advance that target to compound discovery. For each target that has been advanced to compound discovery, Lilly will have the option to obtain an exclusive license with respect to the compounds and products directed to the target. If Lilly does not exercise its option with respect to a given target or has previously exercised all of its options, the Company will have the option to obtain licenses with respect to compounds and products directed to that target. Following option exercise by a party, the development and commercialization of any products directed to the target will be conducted by the exercising party. The exercising party must use commercially reasonable efforts to develop, seek regulatory approval for and commercialize any such products under mutually agreed upon work plans.

        In November 2018, the Company received an upfront, non-refundable payment of $25.0 million under the Lilly Agreement and a concurrent $15.0 million equity investment. In addition, the Company will receive quarterly research and development support payments during a portion of the research term as well as option exercise fees upon option exercises by Lilly.

        Pursuant to the Lilly Agreement, Lilly may owe an aggregate of up to $1.4 billion in development and regulatory milestones and sales milestones. Additionally, Lilly will pay mid to high single-digit royalties on net sales for all products directed to each target optioned by Lilly. Upon the Company's exercise of an option with respect to a given target, the Company will pay Lilly an option exercise payment and may become obligated to milestone and royalty payments. The company may owe an aggregate of up to $710.0 million in development and regulatory milestones and sales milestones.

        Upon the adoption of ASC 606, the Company evaluated the Lilly Agreement under the provisions of ASC 606 and concluded that Lilly is a customer prior to the exercise of its option to obtain an exclusive license with respect to the compounds and products directed to a target that has been advanced to compound discovery. The Company identified the following material promises under the Lilly Agreement: (i) a limited research license to conduct activities under the research collaboration; (ii) research and development services together with the provision of a data package in connection with Lilly's option; (iii) various governance obligations, most notably participation on the joint steering committee; and (iv) rights related to an optional term extension by Lilly. The Company evaluated Lilly's option to obtain an exclusive license with respect to the compounds and products directed to a target that has been advanced to compound discovery and concluded that the option was not issued at a significant and incremental discount, and therefore does not provide material rights. As such, they are excluded as performance obligations at the outset of the arrangement. The Company determined that the research license was not capable of being distinct and the related research and development services and governance activities are not distinct in the context of the contract and, as such, the Company determined that these promises should be combined into a single performance obligation, resulting in a total of two performance obligations under the Lilly Agreement; one for research and development services and one for the right related to an optional term extension by Lilly.

5. Agreement with Eli Lilly and Company (Continued)

        The transaction price at the outset of the arrangement was determined to be $32.7 million, comprised of the upfront fee received from Lilly, quarterly research and development support payments to be received from Lilly during a portion of the research term and an equity investment premium as determined by the Company with reference to a valuation of the Company's preferred stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation.

        The transaction price was allocated to the two performance obligations based on their relative standalone selling price determined with reference to the Company's estimated costs attendant to the obligations. Revenue allocated to the research and development performance obligation is being recognized as the research and development services are provided using an input method according to research and development costs incurred to date compared to estimated total research and development costs. The transfer of control occurs over this time period and, in management's judgment, is the best measure of progress towards satisfying the performance obligation. Revenue allocated to Lilly's right related to an optional term extension is deferred until the right is exercised or lapses, and will subsequently be recognized accordingly.

        While the Lilly Agreement was executed in November 2018, the Company's performance initiated in January 2019. Under the Lilly Agreement, the Company recognized revenue of $1.4 million and $2.8 million for the three and six months ended June 30, 2019, respectively. As of June 30, 2019, deferred revenue included in the Company's balance sheets comprised the following (in thousands):

Operating Leases

        The Company subleases its facilities under a non-cancelable operating sublease agreement. The sublease commenced on February 9, 2016 and, as amended, expires on August 31, 2025. The Company is also responsible for its prorated share of the sublandlord's operating expense.

        On January 30, 2019, the Company entered into a new lease to be used for office and laboratory space, which the Company took possession of in June 2019.

first 10 months is abated, after which the base rent of the lease is $19,650 per month, with an increase in annual rent of 3.0% in each subsequent year of the lease term. In connection with this lease, the Company executed a letter of credit of $39,000, which has not been drawn down on.

        On March 15, 2019, the Company entered into an amended and restated sublease that covers the Company's existing space plus additional square footage to be used as office space, which the Company took possession of upon entering into the amended and restated sublease.

Legal Proceedings

        The Company, from time to time, may be party to litigation arising in the ordinary course of business. The Company is not a party to any litigation or legal proceedings, nor is management aware of any pending or threatened litigation that, in the opinion of the Company's management, are likely to have a material adverse effect on the Company's business. At each reporting date, the Company evaluates whether a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company expenses the costs related to its legal proceedings as incurred.

7. Term Loan

        In April 2016, the Company entered into a $1.0 million term loan with a commercial bank (the "Term Loan"). On January 25, 2019, the Company amended the Term Loan to increase the Company's borrowing capacity to $5.0 million, which amount remains secured by the Company's certificates of deposit, money market account, investment property and deposit or investment accounts. As amended, the Term Loan bears interest at the greater of the prime rate less 1% and 4.25%. The effective interest rate was 4.5% for the three and six months ended June 30, 2019. The effective interest rate was 3.79% and 3.66% for the three and six months ended June 30, 2018, respectively. Under the Term Loan, the Company is required to make monthly interest-only payments through January 2020 and is required to make 36 equal monthly payments of principal plus accrued interest thereafter through January 2023.

        The NextCure, Inc. 2015 Omnibus Incentive Plan (the "2015 Plan") provides for the Company to grant incentive stock options or nonqualified stock options, restricted stock awards, unrestricted stock awards or restricted stock units to employees, consultants and directors of the Company. The 2015 Plan is administered by the board of directors, or at the discretion of the board of directors, by a committee of the board of directors. The exercise prices, vesting and other restrictions are determined at the discretion of the board of directors or its committee if so delegated, except that the exercise price per share of the stock options may not be less than 100% of the fair market value of a share of the Company's common stock on the date of grant and the term of the stock options may not be greater than 10 years.

        On May 3, 2019, the Company's stockholders approved the NextCure, Inc. 2019 Omnibus Incentive Plan (the "2019 Plan"), which became effective on May 8, 2019, the date on which the Registration Statement was declared effective (the "Effective Date"). The 2019 Plan replaces the 2015 Plan as the Company's board of directors (the "Board") determined not to make additional awards under the 2015 Plan following the effectiveness of the 2019 Plan. The 2019 Plan provides for the grant of awards of options, stock appreciation rights, restricted stock, restricted stock units, deferred stock units, unrestricted stock, dividend equivalent rights, other equity-based awards and cash bonus awards to the Company's officers, employees, non-employee directors and other key persons (including consultants). The number of shares of common stock reserved for issuance under the 2019 Plan is 2,900,000 plus the number of shares of stock related to awards outstanding under the 2015 Plan that subsequently terminate by expiration or forfeiture, cancellation or otherwise without the issuance of such shares. The number of shares reserved for issuance under the 2019 Plan will automatically increase on January 1, 2020 and each January 1st thereafter during the term of the 2019 Plan by 4% of the number of shares of the Company's common stock outstanding on December 31st of the preceding calendar year or such lesser number of shares determined by the Board.

        As of June 30, 2019, 2,689,725 shares were available for future issuance under the 2019 Plan.

8. Stock-Based Compensation (Continued)

        Stock options granted under the 2015 Plan and 2019 Plan (together, the "Plans") to employees generally vest over four years and expire after ten years.

(1)
The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the estimated fair value of the common stock for the options that were in the money at June 30, 2019 and December 31, 2018

        The weighted-average grant date fair value of stock options granted to employees for the six months ended June 30, 2019 was $9.86. The aggregate intrinsic value of stock options exercised during the six months ended June 30, 2019 was $396,400.

        The Company's potential dilutive securities, which as of June 30, 2019 include common stock options, have been excluded from the computation of diluted net loss per share as the effect would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded 2,237,777 potential shares of common stock, presented based on amounts outstanding at period end, from the computation of diluted net loss per share attributable to common stockholders for the period indicated because including them would have had an anti-dilutive effect.

        On May 3, 2019, the Company's stockholders approved the NextCure, Inc. 2019 Employee Stock Purchase Plan (the "ESPP"), which became effective on the Effective Date. The ESPP is intended to qualify as an "employee stock purchase plan" within the meaning of Section 423(b) of the Internal Revenue Code. A total of 240,000 shares of common stock were reserved for issuance under this plan. In addition, the number of shares of common stock that may be issued under the ESPP will automatically increase on January 1, 2020 and each January 1st thereafter until expiration of the ESPP, in an amount equal to the lesser of (i) 1% of the number of shares of the Company's common stock outstanding on December 31st of the preceding calendar year, (ii) 480,000 shares of common stock and (iii) a number of shares of common stock determined by the administrator of the ESPP.

Stock-Based Compensation

        The Company recorded stock-based compensation expense of $412,000 and $795,000 for the three and six months ended June 30, 2019, respectively, and $24,000 and $48,000 for the three and six months ended June 30, 2018, respectively.

9. Income Taxes

        The Company did not record a provision or benefit for income taxes during the six months ended June 30, 2019. The Company continues to maintain a full valuation allowance against its deferred tax assets.

        The Company has evaluated the positive and negative evidence involving its ability to realize its deferred tax assets. Management has considered the Company's history of cumulative net losses incurred since inception and its lack of any commercially ready products. It has concluded that it is more likely than not that the Company will not realize the benefits of the deferred tax assets including net operating loss carryforwards and research and development credits. Management reevaluates the positive and negative evidence at each reporting period.

        Under the provisions of Sections 382 and 383 of the Internal Revenue Code, certain substantial changes in the Company's ownership may have limited, or may limit in the future, the amount of net operating loss and research and development credit carryforwards that can be used to reduce future income taxes.

10. Subsequent Events

        On August 2, 2019, the Company entered into a lease amendment for additional square feet to be used for office, laboratory and warehouse space, which the Company expects the landlord to deliver in April 2020. The amended lease is expected to expire on March 31, 2030. Base rent for the first seven months is abated with respect to the additional space, after which the base rent of the lease is $18,178 per month for that space, with an increase in annual rent of 3.0% in each subsequent year of the lease term.

Item 14.    Indemnification of Directors and Officers.

        We are incorporated under the laws of the State of Delaware. As permitted by Section 102 of the Delaware General Corporation Law, we have adopted provisions in our amended and restated certificate of incorporation and bylaws that limit or eliminate the personal liability of our directors for a breach of their fiduciary duty of care as a director. The duty of care generally requires that, when acting on behalf of the corporation, directors exercise an informed business judgment based on all material information reasonably available to them. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for:

        These limitations of liability do not affect the availability of equitable remedies such as injunctive relief or rescission. Our amended and restated certificate of incorporation also authorizes us to indemnify our officers, directors and other agents to the fullest extent permitted under Delaware law.

        As permitted by Section 145 of the Delaware General Corporation Law, our amended and restated bylaws provide that:

Pursuant to 17 C.F.R. Section 200.83

        Our amended and restated certificate of incorporation, attached as Exhibit 3.1 hereto, and our amended and restated bylaws, attached as Exhibit 3.2 hereto, provide for the indemnification provisions described above and elsewhere herein.

        We have entered and expect to continue to enter into agreements to indemnify our directors, executive officers and other employees as determined by our board of directors. These indemnification agreements generally require us, among other things, to indemnify our directors, executive officers and these employees against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct. These indemnification agreements also generally require us to advance any expenses incurred by the directors, executive officers and employees as a result of any proceeding against them as to which they could be indemnified. We also maintain directors' and officers' liability insurance that insures our directors and officers against the cost of defense, settlement or payment of a judgment in some circumstances.

        The form of Underwriting Agreement, attached as Exhibit 1.1 hereto, provides for indemnification by the underwriters named in this registration statement of our executive officers, directors and us, and by us of the underwriters named in this registration statement, for specified liabilities, including liabilities arising under the Securities Act. Our amended and restated investors' rights agreement with certain stockholders, attached as Exhibit 4.2 hereto, also provides for cross-indemnification in connection with the registration of our common stock on behalf of such investors.

        See the undertakings set forth in response to Item 17 herein.

Item 15.    Recent Sales of Unregistered Securities.

        The following list sets forth information regarding all securities sold or granted by us within the last three years that were not registered under the Securities Act and the consideration, if any, received by us for such securities.

Issuances of Capital Stock

Grants of Stock Options and Restricted Stock

        We deemed the offers, sales and issuances of the securities described in paragraphs (1) through (5) above to be exempt from registration under the Securities Act, in reliance on Section 4(a)(2) of the Securities Act, including Regulation D and Rules 504 and 506 promulgated thereunder, relative to transactions by an issuer not involving a public offering. All purchasers of securities in transactions exempt from registration pursuant to Regulation D represented to us that they were accredited investors and were acquiring the shares for investment purposes only and not with a view to, or for sale in connection with, any distribution thereof and that they could bear the risks of the investment and could hold the securities for an indefinite period of time. The purchasers received written disclosures that the securities had not been registered under the Securities Act and that any resale must be made pursuant to a registration statement or an available exemption from such registration.

        We deemed the issuance of restricted common stock and grants and exercises of stock options described in paragraphs (6) and (7) above to be exempt from registration under the Securities Act in reliance on Rule 701 of the Securities Act as offers and sales of securities under compensatory benefit plans and contracts relating to compensation in compliance with Rule 701. Each of the recipients of securities in any transaction exempt from registration either received or had adequate access, through employment, business or other relationships, to information about us.

        All of the foregoing securities are deemed restricted securities for purposes of the Securities Act. All certificates representing securities issued in the transactions described in this Item 15 included appropriate legends setting forth that the securities had not been offered or sold pursuant to a registration statement and describing the applicable restrictions on transfer of the securities. There were no underwriters employed in connection with any of the transactions set forth in this Item 15.

Item 16.    Exhibits and Financial Statement Schedules.

        See the Index to Exhibits attached to this registration statement, which is incorporated by reference herein.

        No financial statement schedules are provided, because the information called for is not required or is shown either in the financial statements or the notes thereto.

Item 17.    Undertakings.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions or otherwise, the

registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

        The undersigned registrant hereby undertakes that:

Exhibit 10.15

 

Portions of this exhibit indicated by bracketed asterisks have been omitted because they are not material and would likely cause competitive harm to NextCure, Inc. if publicly disclosed.

 

FIRST AMENDMENT TO LEASE AGREEMENT

 

THIS FIRST AMENDMENT TO LEASE AGREEMENT (“this First Amendment”) is dated as of August 2, 2019 (“Effective Date”), by and between ARE-8000/9000/10000 VIRGINIA MANOR, LLC, a Delaware limited liability company, having an address at 385 E. Colorado Boulevard, Suite 299, Pasadena, California 91101 (“Landlord”), and NEXTCURE, INC., a Delaware corporation, having an address at Suite 140, 8000 Virginia Manor Road, Beltsville, Maryland 20705 (“Tenant”).

 

RECITALS

 

A.                                    Landlord and Tenant have entered into that certain Lease Agreement (“Lease”) dated as of January 30, 2019, wherein Landlord leased to Tenant approximately 14,075 rentable square feet (“Existing Premises”) located at Suite 140, 8000 Virginia Manor Road, Beltsville, Maryland 20705, as more particularly described in the Lease.

 

B.                                    Landlord and Tenant desire to amend the Lease, among other things, to expand the Existing Premises by an additional 14,446 rentable square feet located adjacent to the Existing Premises (“Expansion Premises”).

 

AGREEMENT

 

Now, therefore, the parties hereto agree that the Lease is amended as follows:

 

1.                                      Definitions; Recitals. Terms used in this First Amendment but not otherwise defined shall have the meanings set forth in the Lease. The Recitals form an integral part of this First Amendment and are hereby incorporated by reference.

 

2.                                      Expansion Premises. Effective as of the Expansion Premises Commencement Date (as defined below), (a) the Existing Premises shall be expanded to include the Expansion Premises, and (b) Exhibit A to this First Amendment, which depicts the Expansion Premises as the hatched area, is hereby added to Exhibit A to the Lease.

 

3.                                      Changes to Defined Terms. Effective as of the Expansion Premises Commencement Date, the following amendments are hereby made to the definitions contained on pages 1 and 2 of the Lease in the Basic Lease Provisions.

 

a.              The defined term “Premises (before 9000 VMR Effective Date)” shall be deleted in its entirety and replaced with the following:

for any loss or damage resulting therefrom, and this First Amendment and the Lease with respect to the Expansion Premises shall not be void or voidable.

 

a.              Except as set forth in this First Amendment, if applicable: (i) Tenant shall accept the Expansion Premises in their broom clean condition as of the Expansion Premises Commencement Date, which condition shall be substantially similar in all material respects to the condition of the Expansion Premises as of the Effective Date; (ii) Landlord shall have no obligation for any defects in the Expansion Premises, and (iii) Tenant’s taking possession of the Expansion Premises shall be conclusive evidence that Tenant accepts the Expansion Premises and that the Expansion Premises were in good condition at the time possession was taken. Notwithstanding the provisions of this Section, Tenant shall have a period of 90 days after Landlord’s Delivery of the Expansion Premises to Tenant to reasonably identify in writing any (A) all or any part of the HVAC and life safety systems serving the Expansion Premises that are not in good working order, and (B) latent defects in the mechanical, electrical, and plumbing systems and the structural components serving the Expansion Premises. For purposes of this paragraph, “latent defects” means those material defects in such systems and/or components that could not have been identified or discovered through a reasonable inspection of such systems or components conducted by a qualified technician. Landlord will promptly repair the items described in clauses (A) and (B) above (subject to Landlord’s reasonable confirmation that such items described in clause (A) are not in good working order, and the defects described in clause (B) are, in fact, latent defects).

 

b.              Neither Landlord nor any of its agents has made any representation or warranty with respect to the condition of all or any portion of the Expansion Premises, and/or the suitability of the Expansion Premises for the conduct of Tenant’s business, and Tenant waives any implied warranty that the Expansion Premises are suitable for the Permitted Use. Tenant shall use the Expansion Premises only for the Permitted Use under the Lease in compliance with the provisions of Section 7 of the Lease.

 

c.               Landlord shall have no obligation to perform any work at the Building in connection with Tenant’s occupancy of the Expansion Premises or obtain any permits, approvals, or entitlements related to Tenant’s specific use of the Expansion Premises or Tenant’s business operations therein.

 

d.              As of the Effective Date, Landlord is leasing (i) Expansion Premises #1 to [***], and the lease agreement (“[***] Lease”) between Landlord and [***] is scheduled to expire on February 29, 2020, and (ii) Expansion Premises #2 to [***], and the lease agreement (“[***] Lease”) between Landlord and [***] is scheduled to expire on March 31, 2020. Tenant understands, acknowledges, and agrees that Landlord makes no

guaranty, representation, or assurance that Landlord will be able to Deliver the Expansion Premises to Tenant by the Expansion Premises Commencement Date and that Landlord shall have no obligation or duty to seek the vacation or removal of [***] and [***] from Expansion Premises #1 and Expansion Premises #2, respectively. If Landlord is unable to Deliver the Expansion Premises to Tenant on April 1, 2020 by reason of the failure of [***] and [***] to vacate Expansion Premises #1 and Expansion Premises #2, respectively, by March 31, 2020, the Expansion Premises Commencement Date shall be extended for one day for each day after April 1, 2020 until the date on which the Expansion Premises Commencement Date occurs. To illustrate the operation of this paragraph, assume that Landlord Delivers the Expansion Premises to Tenant on April 10, 2020 because [***] or [***], or both, did not vacate the Expansion Premises until April 9, 2020. Based on that assumption, the Expansion Premises Commencement Date would be extended by 10 calendar days. In addition, if Landlord is unable to Deliver both Expansion Premises #1 and Expansion Premises #2 on or before July 31, 2020, Tenant shall have the right to terminate this First Amendment by sending written notice thereof to Landlord by no later than August 31, 2020, whereupon neither Landlord nor Tenant shall have any further rights, duties, or obligations under this First Amendment. If Tenant does not elect to so terminate this First Amendment by August 31, 2020, such right to terminate this First Amendment shall be waived.

 

Notwithstanding any contrary provision in this First Amendment, if Landlord Delivers to Tenant before April 1, 2020 either or both of Expansion Premises #1 and Expansion Premises #2, Tenant shall have immediate access to such premises without an obligation to pay Base Rent during such access before April 1, 2020. Tenant, however, shall pay, as Additional Rent, the cost of any utilities consumed therein for the period before April 1, 2020. Before any such access, Tenant shall provide to Landlord the required proof of insurance coverage as set forth in the Lease.

 

e.               Tenant, at its sole expense, shall make any alterations or modifications to the interior of the Expansion Premises that are required by Legal Requirements (including, without limitation, compliance of the Expansion Premises with the ADA; provided, however, that Landlord shall, at no cost or expense to Tenant, make alterations or modifications to the interior of the Expansion Premises to the extent that (i) the Expansion Premises do not comply with the ADA as of the Expansion Premises Commencement Date, and (ii) Tenant notifies Landlord of such non-compliance within 90 days after the Expansion Premises Commencement Date (which notification shall be based on a written report obtained by Tenant and prepared by Tenant’s architect licensed by the State of Maryland, which report Tenant shall provide to Landlord along with such notification).

5.                                      Base Rent for Expansion Premises. (a) Tenant shall continue to pay Base Rent with respect to the Existing Premises at the rates set forth in the Lease, (b) commencing on the Expansion Premises Commencement Date (but subject to the Expansion Premises Base Rent Abatement [as defined below]), Base Rent for the Expansion Premises shall be payable at the rate of $[***] per month, and (c) commencing on the Expansion Premises Commencement Date, Base Rent for the Expansion Premises shall be increased as of the date or dates on which Tenant uses the Additional Expansion Premises TI Allowance (as defined in the Expansion Premises Work Letter attached hereto as a part hereof as Exhibit C) (such increase to be calculated based on the amount of the Additional Expansion Premises TI Allowance used by Tenant, such amount to be amortized over the Base Term based on an interest rate of [***]% per annum; the resulting amount so amortized shall be added to the monthly installments of Base Rent for the Expansion Premises). Notwithstanding any contrary provision contained in the Lease, the Base Rent for the Expansion Premises shall thereafter be increased on each anniversary of the Expansion Premises Commencement Date (which, solely for purposes of determining such increase, shall be April 1, 2020 if the Expansion Premises Commencement Date occurs before such date) by multiplying the Base Rent payable for the Expansion Premises immediately before such date by the Rent Adjustment Percentage and adding the resulting amount to the Base Rent payable for the Expansion Premises immediately before such date; provided, however, that as more fully set forth in Section 5(b)2 of the Work Letter, the Rent Adjustment Percentage shall not apply to the Additional Expansion Premises TI Allowance. Base Rent for the Expansion Premises, as so adjusted, shall thereafter be due as provided in the Lease.

 

a.              Expansion Premises Base Rent Abatement. Notwithstanding anything to the contrary contained in this First Amendment, but provided Tenant is not in Default hereunder or under the Lease, Landlord hereby grants Tenant an abatement of the Base Rent payable with respect to the Expansion Premises during the period beginning on the Expansion Premises Commencement Date and ending 7 months after the Expansion Premises Commencement Date (“Expansion Premises Base Rent Abatement”). For the avoidance of doubt, if the Expansion Premises Commencement Date occurs on the first day of a month, the Expansion Premises Base Rent Abatement will be measured from that date. If the Expansion Premises Commencement Date occurs on a day other than the first day of a month, the Expansion Premises Base Rent Abatement will be measured from the first day of the following month. Except as provided in the preceding sentences, Tenant shall pay the full amount of Base Rent due with respect to the Expansion Premises in accordance with the provisions of this First Amendment and the Lease. The administration rent set forth in Section 5 of the Lease shall not be abated and shall be based on the amount of Base Rent with respect to the Expansion Premises that would have been payable but for the Expansion Premises Base Rent Abatement. Notwithstanding anything to the contrary in this Section 5(a) the adjustment in the Base Rent as set forth in this Section 5 shall be based on the full and unabated amount of Base Rent payable with respect to the Expansion Premises for the first 12 month period from and after the Expansion Premises Commencement Date (which, solely for purposes of determining the commencement date of the Expansion Premises Base Rent

 

6


 

Abatement, shall be April 1, 2020 if the Expansion Premises Commencement Date occurs before such date). To illustrate the operation of the foregoing parenthetical, assume that the Expansion Premises Commencement Date is March 27, 2020. Based on that assumption, the Expansion Premises Commencement Date would be assumed to have commenced on April 1, 2020 for purposes of determining the commencement of the Expansion Premises Base Rent Abatement and the date for increasing the Base Rent for the Expansion Premises.

 

6.                                      Extension Right. The Extension Right set forth in Section 40 of the Lease applies to, and shall be exercised (if at all) only with respect to, the entire Premises. The Extension Term shall be for the period beginning on April 1, 2030 and ending, unless earlier terminated in accordance with the terms and conditions of the Lease, on March 31, 2035. For the avoidance of doubt, the Market Rate shall not include the adjustments for the TI Allowance as described in Section 4 of the Lease and the Expansion Premises TI Allowance as described in Section 5 of this First Amendment, but may include build-out allowances to the extent they are then provided as market concessions in the Market Area.

 

7.                                      Expansion Right. As of the Expansion Premises Commencement Date, the Available Space will no longer include (a) Suite 110 (8000 VMR Building) as shown in the table in Section 39(a) of the Lease since that area constitutes Expansion Premises #1, and (b) Suite 170 (8000 VMR Building) as shown in the table in Section 39(a) of the Lease since that area constitutes Expansion Premises #2. Accordingly, the table set forth in Section 39(a) of the Lease is hereby deleted and replaced with the table below:

Landlord shall have the right to approve the place, size, and design of the Identification Sign, which approval shall not be unreasonably withheld, delayed, or conditioned and shall in all cases comply with building standard signage requirements (except as to font and logo).

Tenant shall substantially complete or cause to be substantially completed the Expansion Premises Tenant Improvements in a good and workmanlike manner, in accordance with the TI Permit subject, in each case, to Minor Variations and normal “punch list” items of a non-material nature that do not interfere with the use of the Expansion Premises (“Substantial Completion” or “Substantially Complete”).

For purposes of this Expansion Premises Work Letter, “Minor Variations” shall mean any modifications reasonably required: (i) to comply with all applicable Legal Requirements and/or to obtain or to comply with any required permit (including the TI Permit); (ii) to comport with good design, engineering, and construction practices which are not material; or (iii) to make reasonable adjustments for field deviations or conditions encountered during the construction of the Expansion Premises Tenant Improvements.

 

4.              Changes. Any changes requested by Tenant to the Expansion Premises Tenant Improvements after the delivery and approval by Landlord of the TI Design Drawings, shall be requested and instituted in accordance with the provisions of this Section 4 and shall be subject to the written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed.

 

(a)                                 Tenant’s Right to Request Changes. If Tenant shall request changes (“Changes”), Tenant shall request such Changes by notifying Landlord in writing in substantially the same form as the AIA standard change order form (a “Change Request”), which Change Request shall detail the nature and extent of any such Change.

Landlord shall review and approve or disapprove such Change Request within 7 business days thereafter, provided that Landlord’s approval shall not be unreasonably withheld, conditioned or delayed.

 

(b)                                 Implementation of Changes. If Landlord approves such Change and Tenant deposits with Landlord any Excess Expansion Premises TI Costs (as defined in Section 5(d) below) required in connection with such Change, Tenant may cause the approved Change to be instituted. If any TI Permit modification or change is required as a result of such Change, Tenant shall promptly provide Landlord with a copy of such TI Permit modification or change.

17


 

Landlord for Landlord’s approval, which shall not be unreasonably withheld or delayed. The Budget shall be based upon the TI Construction Drawings approved by Landlord and shall include a payment to Landlord of administrative rent (“Administrative Rent”) equal to [***]% of the Expansion Premises TI Costs (as defined below) for monitoring and inspecting the construction of the Expansion Premises Tenant Improvements, which sum shall be payable from the Expansion Premises TI Allowance. Such Administrative Rent shall include, without limitation, all third party, out-of-pocket costs, expenses, and fees incurred by or on behalf of Landlord arising from, out of, or in connection with, such monitoring of the construction of the Expansion Premises Tenant Improvements, and shall be payable out of the Expansion Premises TI Allowance. If the Budget is greater than the Expansion Premises TI Allowance, Tenant shall deposit with Landlord the difference, in cash, prior to the commencement of construction of the Expansion Premises Tenant Improvements, for disbursement by Landlord as described in Section 5(d).

 

(b)                                 Expansion Premises TI Allowance. Landlord shall provide to Tenant a tenant improvement allowance (collectively, “Expansion Premises TI Allowance”) as follows:

 

1.                                      first, Landlord shall provide and disburse a “Base Expansion Premises TI Allowance” in the maximum amount of $[***] per rentable square foot in the Expansion Premises, or $[***] in the aggregate (i.e., $[***] x 14,446 rsf), which is included in the Base Rent set forth in the First Amendment; and

 

2.                                      then, upon full disbursement of the Base Expansion Premises TI Allowance, Landlord shall provide and disburse an “Additional Expansion Premises TI Allowance” in the maximum amount of $[***] per rentable square foot in the Expansion Premises, or $[***] in the aggregate (i.e., $[***] x 14,446 rsf), which shall, to the extent used, result in adjustments to the Base Rent for the Expansion Premises as set forth in the First Amendment but shall not be included in Base Rent for the purposes of calculating the annual Base Rent increase described in Section 5 of this First Amendment. Notwithstanding any contrary provision set forth in this First Amendment, Tenant shall be permitted to use the Additional Expansion Premises TI Allowance for the Expansion Premises Tenant Improvements (with respect to the Expansion Premises) or the Tenant Improvements (with respect to the Existing Premises).

 

Before commencing the Expansion Premises Tenant Improvements, Tenant shall notify Landlord how much Additional Expansion Premises TI Allowance Tenant has elected to receive from Landlord (Elected Amount”). Such election shall be final and binding on Tenant, and may not thereafter be modified without Landlord’s consent, which may be granted or withheld in Landlord’s sole and absolute subjective discretion. The Expansion Premises TI Allowance shall be disbursed in accordance with this Expansion Premises Work Letter.

 

Tenant shall have no right to the use or benefit (including any reduction to Base Rent for the Expansion Premises) of any portion of the Expansion Premises TI Allowance not

 

18


 

required for (i) the design and construction of the Expansion Premises Tenant Improvements described in the TI Construction Drawings approved pursuant to Section 2(d), (ii) the design and construction of any Changes pursuant to Section 4, (iii) assessment of vapor/moisture for any portion of the Premises, including without limitation the Expansion Premises, (iv) the reasonable costs of space planning, architectural, engineering, and construction management fees, and (v) with respect to the Additional Expansion Premises TI Allowance, (A) the design and construction of the Existing Premises Tenant Improvements, (B) the design and construction of any Changes regarding the Existing Premises, (C) the reasonable costs of space planning, architectural, engineering, and construction management fees regarding the Existing Premises. Regardless of the timing incident to the approval of the TI Design Drawings and the TI Construction Drawings as set forth in Sections 2(b) and 2(c) above, respectively, in no event whatsoever shall Tenant have any right to any portion of the Expansion Premises TI Allowance that is not disbursed before the last day of the month that is 18 months after the Expansion Premises Commencement Date (“Disbursement Deadline”). If all or any portion of the Additional Expansion Premises TI Allowance is not disbursed by the Disbursement Deadline, for purpose of calculating the Base Rent for the Expansion Premises and adjustments thereto under the First Amendment, Tenant shall be deemed to have been disbursed the entire Elected Amount of the Additional Expansion Premises TI Allowance by the Disbursement Deadline. As a result, the Base Rent for the Expansion Premises shall be adjusted as though Tenant had been disbursed the entire Elected Amount of the Expansion Premises TI Allowance by the Disbursement Deadline.

 

(c)                                  Costs Includable in Expansion Premises TI Allowance. The Expansion Premises TI Allowance shall be used solely for the payment of design, permits, and construction costs in connection with the construction of the Expansion Premises Tenant Improvements (and such additional items as described in Section 5(b)2(v) above), including, without limitation, the cost of electrical power and other utilities used in connection with the construction of the Expansion Premises Tenant Improvements, the cost of preparing the space plans/test fits, TI Design Drawings, and the TI Construction Drawings, all costs set forth in the Budget, including Landlord’s Administrative Rent, the cost of Changes, demolition costs, “soft” costs for fees of architects and other professionals engaged in connection with the performance of the Expansion Premises Tenant Improvements, and equipment installed within the Expansion Premises (which equipment shall be surrendered to Landlord at the expiration or earlier termination of the Term except for such equipment that Tenant has to the right to remove in accordance with the terms and conditions of Section 12 of the Lease), and built-in lockers and built-in file cabinets (collectively, “Expansion Premises TI Costs”). Notwithstanding anything to the contrary contained herein but subject to the terms of the preceding sentence, the Expansion Premises TI Allowance shall not be used to purchase any furniture, personal property or other non-Building system materials or equipment, including, but not be limited to, Tenant’s voice or data cabling, non-ducted biological safety cabinets and other scientific equipment not incorporated into the Expansion Premises Tenant Improvements.

If and when any such Installation is replaced, Tenant shall promptly notify Landlord in writing of the precise identifying information for such replacement Installation.

 

(d)                                 Excess Expansion Premises TI Costs. Landlord shall have no obligation to bear any portion of the cost of any of the Expansion Premises Tenant Improvements except to the extent of the Expansion Premises TI Allowance. Notwithstanding anything to the contrary set forth in this Section 5(d), Tenant shall be fully and solely liable for Expansion Premises TI Costs and the cost of Minor Variations in excess of the Expansion Premises TI Allowance.

 

(e)                                  Payment for Expansion Premises TI Costs. During the course of design and construction of the Expansion Premises Tenant Improvements, Landlord shall pay Expansion Premises TI Costs once a month against a draw request in Landlord’s standard form (which form shall be the AIA standard requisition form or other form reasonably acceptable to Landlord and Tenant) containing such certifications, lien waivers (including a conditional lien release for each progress payment and unconditional lien releases for the prior month’s progress payments), inspection reports and other matters as Landlord customarily obtains, no later than 30 days following receipt of such draw request. Upon completion of the Expansion Premises Tenant Improvements (and prior to any final disbursement of the Expansion Premises TI Allowance), Tenant shall deliver to Landlord: (i) sworn statements setting forth the names of all contractors and first tier subcontractors who did the work and final, unconditional lien waivers from all such contractors and first tier subcontractors; (ii) as-built plans (one copy in print format and two copies in electronic CAD format) for the Expansion Premises Tenant Improvements; (iii) a certification of substantial completion in Form AIA G704, (iv) a certificate of occupancy for the Expansion Premises; and (v) copies of all operation and maintenance manuals and warranties affecting the Expansion Premises.
