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.

We currently have three product candidates in clinical development. We are
focusing our efforts on the LAIR programs with NC410 (LAIR-2 fusion) in a Phase
1b/2 clinical trial in combination with pembrolizumab and NC525 (LAIR-1 mAb),
for which we filed an investigational new drug (IND) application with the US
Food and Drug Administration (FDA) and anticipate initiating a Phase 1 trial in
the first quarter of 2023. In addition, NC762 (B7-H4 mAb) advanced into a Phase
1b cohort expansion study.

NC410

NC410 is a novel immunomedicine designed to block immune suppression mediated by
an immune modulator called Leukocyte-Associated Immunoglobulin-like Receptor, or
"LAIR", -1.  In June 2020, we initiated a Phase 1/2 clinical trial of NC410 in
patients with advanced or metastatic solid tumors. The Phase 1 dose-escalation
portion of this open-label trial was designed to evaluate the safety and
tolerability of NC410 in patients with advanced or metastatic solid tumors and
determine its pharmacologically active and/or maximum tolerated dose.

The Phase 1 clinical trial enrolled a total of 40 patients across 7 cohorts
ranging from 3 mg up to 200 mg.  NC410 has been shown to be safe and
well-tolerated up to 200 mg once every 2 weeks (Q2W).  Notable treatment-
related adverse events included infusion reactions, anemia and a worsening of a
baseline lymphopenia. The best response achieved was stable disease greater than
12 weeks in 8 patients across different doses and indications.  Based on the
preclinical and

                                       14

  Table of Contents

clinical data to date, we have determined a combination strategy to be more likely for clinical response in a Phase 1b/2 instead of a monotherapy approach.


In October 2022, we announced the initiation of a Phase 1b/2 clinical trial to
evaluate NC410 in combination with KEYTRUDA® (pembrolizumab), Merck's anti-PD-1
therapy, in immune checkpoint refractory patients (colorectal, esophageal,
endometrial and head and neck cancers) or immune checkpoint naïve solid tumor
patients (colorectal and ovarian cancers). The rationale for moving directly
into a combination trial for NC410 is based on NC410's mechanism of action, as
seen in preclinical modeling and also during the NC410 Phase 1 dose escalation
study readouts. It has been shown that elevated collagen levels in the
extracellular matrix (ECM), the tissue matrix surrounding the tumor, are
associated with resistance to PD-1 and PD-L1 therapies. In non-clinical
colorectal models and early-stage monotherapy clinical studies conducted by
NextCure, we have demonstrated that NC410 can remodel collagen in the ECM, which
enhances T cell infiltration into the tumor. This results in immune activation,
enhanced immune function in the TME and significantly enhances anti-PD-1
activity in multiple preclinical tumors models. We believe that this may
translate to improved responses in patients with immune checkpoint refractory or
immune checkpoint naïve solid tumors.

The Company entered into a supply agreement for KEYTRUDA with Merck (known as MSD outside the United States and Canada) for the Phase 1b/2 clinical trial.

NC525



NC525 is a novel LAIR-1 antibody that selectively targets Acute Myeloid
Leukemia, or "AML", blast cells and leukemic stem cells, or "LSCs". Preclinical
data show that NC525 kills AML blast cells and LSCs while sparing hematopoietic
stem and progenitor cells, or "HSPCs". Preclinical data were presented at the
American Society for Hematology annual meeting in December 2021. The data showed
that NC525 (i) inhibits colony formation of AML LSCs in vitro, (ii) inhibits AML
growth in the MV4-11 derived xenografts animal model in vivo and (iii) restricts
AML progression in patient-derived xenografts in vivo. An IND was submitted with
the FDA and we have received clearance to proceed.  We plan to initiate a Phase
1 clinical study in the first quarter 2023.

NC762



NC762 is an immunomedicine targeting an immunomodulatory molecule called human
B7 homolog 4 protein, or "B7-H4". In July 2021, we initiated a Phase 1/2
clinical trial of NC762 in patients with lung cancer, breast cancer, ovarian
cancer or other tumor types. The Phase 1 dose-escalation portion of this
open-label trial was designed to evaluate the safety and tolerability of NC762
and determine its pharmacologically active and/or maximum tolerated dose. The
Phase 1 clinical trial enrolled a total of 18 patients across 5 cohorts ranging
from 0.5 mg up to 20 mg.  NC762 was safe and well-tolerated.

In October 2022, we initiated NC762 into a Phase 1b expansion cohort study dosing at 10 mg and 20 mg using a CLIA-validated assay to select patients with B7-H4 expression in tumor types including NSCLC, ovarian, endometrial, hepatocellular and breast.

NC318



In November 2022, we announced that NC318 would not move forward in the amended
Phase 2 monotherapy clinical trial.   Although NC318 has been shown to be safe
and well-tolerated in patients, we saw no responses in the amended Phase 2
portion of the trial and, based on the totality of the NC318 monotherapy data,
we will wind down the clinical study while ensuring that patients on study have
access to NC318.

The Company will continue to support Yale University's ongoing Phase 2 investigator initiated trial of NC318 in combination with pembrolizumab in NSCLC patients.

COVID-19

In March 2020, the World Health Organization declared the novel coronavirus
disease 2019 ("COVID-19") outbreak a pandemic. In order to mitigate the spread
of COVID-19, governments have imposed unprecedented restrictions on business
operations, travel, and gatherings, resulting in a global economic downturn and
other adverse economic and societal impacts. The COVID-19 pandemic has also
overwhelmed or otherwise led to changes in the operations of many healthcare
facilities, including clinical trial sites. However, our laboratories have
continued operations throughout the pandemic mostly without interruption.

The impact of the COVID-19 pandemic (including the impact of emerging variant
strains of the COVID-19 virus) on our business and financial performance is
uncertain and depends on various factors, including the scope and duration of
the pandemic, the efficacy and global distribution of vaccines, government
restrictions and other actions, including relief measures, implemented to
address the impact of the pandemic, and resulting impacts on the financial
markets and overall economy. The imposition of restrictions on business
operations, travel and gatherings by state and federal governments in the United
States as well as governments in other regions of the world in response to the
COVID-19 pandemic initially placed significant strain on our clinical trial
sites, raised concerns around monitoring patient safety, slowed patient
enrollment and caused delays in the Company's clinical trials and issuance of
results. Any rise of COVID-19 infection rates, especially in the United States,
could continue to negatively affect enrollment going forward. We continue to
closely monitor the COVID-19 situation and any potential impact to our planned
activities.

Financial Overview

Since commencing operations in 2015, we have devoted substantially all 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.  Our net loss for the three months ended September 30, 2022
and 2021, was $18.9 million and $17.9 million, respectively, and our net loss
for the nine months ended September 30, 2022 and 2021, was $57.4 million and
$52.5 million, respectively. As of September 30, 2022, we had an accumulated
deficit of $244.5 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 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 public offerings of our common stock, with private placements of our preferred stock and with upfront fees received under our former research and development collaboration agreement with Lilly, or the "Lilly Agreement," which was terminated in March 2020. From our inception through September 30, 2022, we received gross proceeds of $164.4 million through private placements of preferred stock.



In November 2018, we entered into the Lilly Agreement to use our FIND-IO
platform to identify novel oncology targets for additional collaborative
research and drug discovery by us and Lilly. 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. We were also eligible for quarterly research
and development support payments during a portion of the term of the Lilly
Agreement. Effective March 3, 2020, Lilly terminated the Lilly Agreement without
cause.

On May 13, 2019, we closed our initial public offering, or "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.

On November 19, 2019, we completed an underwritten public offering, in which we
issued and sold 4,077,192 shares of common stock at a public offering price of
$36.75 per share. On December 2, 2019, the underwriters exercised in full their
option to purchase an additional 611,578 shares of common stock at the public
offering price of $36.75, for

                                       16

  Table of Contents

total net proceeds to us of approximately $160.9 million, after deducting underwriting discounts and commissions of approximately $10.3 million and offering expenses of approximately $1.0 million.



As of September 30, 2022, we had cash, cash equivalents and marketable
securities, excluding restricted cash, of $169.2 million. We believe that our
existing cash, cash equivalents and marketable securities will be sufficient to
fund our planned operations into mid-2025. 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 Phase 1b/2 clinical trial of NC410 in
combination with pembrolizumab, our planned Phase 1 clinical trial for NC525,
and our ongoing Phase 1/2 clinical trial for NC762, and other research and
development activities. We expect to continue 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 and 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

Through September 30, 2022, we have not generated any revenue from product sales.

Operating Expenses

Research and Development 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:

? salaries, benefits and other related costs, including stock-based compensation,

for personnel engaged in research and development functions;

expenses incurred under agreements with third parties, including agreements

? with third parties that conduct research, preclinical activities or clinical

trials on our behalf, such as our license agreement with Yale University, or

"Yale";

? costs of outside consultants, including their fees, stock-based compensation

and related travel expenses;

? the costs of laboratory supplies and acquiring, developing and manufacturing

preclinical study and clinical trial materials; and

facility-related expenses, which include direct depreciation costs and

? allocated expenses for rent and maintenance of facilities and other operating

costs.


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

                                       17

  Table of Contents

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.

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 and expand the number of trials we are conducting and the
patients enrolled in those trials, as we utilize our current good manufacturing
practice, or "cGMP", manufacturing capacity, including to provide drug supply of
NC410, NC525 and NC762 for future clinical trials, 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 NC410, NC525, NC762 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 NC410, NC525,
NC762 and any other product candidate we may develop will depend on a variety of
factors, including:

the scope, progress, results, and costs of clinical trials of NC410, NC525 and

? NC762, as well as of any future clinical trials of other product candidates and

other research and development activities that we may conduct;

the continued impact of the COVID-19 pandemic, including delays and slowdowns

? as a result of strain on our clinical trial sites and concerns about patient

safety;

? uncertainties in selection of indications, clinical trial design and patient

enrollment rates;

the probability of success for our product candidates, including safety and

? efficacy, early clinical data, competition, ease and ability of manufacturing

and commercial viability;

? significant and changing government regulation and regulatory guidance;

? the timing and receipt of any development or marketing approvals; and

? the expense of filing, prosecuting, defending and enforcing any patent claims

and other intellectual property rights.




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 U.S. Food and Drug Administration 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

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



                                       18

  Table of Contents

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 during the next few years as a result of staff expansion and additional occupancy costs, higher legal and accounting fees, investor relations costs, higher insurance premiums and other compliance costs.

Other Income, Net

Other income, net consists primarily of interest income earned on marketable securities.

We do not allocate personnel-related costs, including stock-based compensation
costs, or other indirect costs to specific programs, as they are deployed across
multiple projects under development and discovery and, as such, are separately
classified as internal research and development expenses in the table above.

Research and development expenses for the three months ended September 30, 2022
were comparable to the three months ended September 30, 2021 as higher internal
research and development expenses were offset by lower external research and
development expenses.

Research and development expenses for the nine months ended September 30, 2022
increased by $3.4 million compared to the nine months ended September 30, 2021.
The increase is a result of $3.4 million higher clinical-related costs,
primarily related to NC410.

Liquidity and Capital Resources



We have financed our operations primarily with proceeds from public offerings of
our common stock, private placements of our preferred stock and upfront fees
received under the Lilly Agreement. 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 net offering proceeds to us of approximately $77.0 million after
deducting underwriting discounts and commissions and offering expenses. On
November 19, 2019, we completed an underwritten public offering in which we sold
4,077,192 shares of common stock at a public offering price of $36.75 per share.
On December 2, 2019, the underwriters exercised in full their option to purchase
an additional 611,578 shares of common stock at a public offering price of
$36.75. Net offering proceeds to us were approximately $160.9 million after
deducting underwriting discounts and commissions and offering expenses. 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.

On May 6, 2021, the Company entered into a sales agreement (the "Sales
Agreement") with SVB Leerink LLC (the "Agent"), pursuant to which the Company
may sell, from time to time, up to an aggregate sales price of $75 million of
its common stock through the Agent in negotiated transactions that are deemed to
be an "at the market offering." The Agent will be entitled to compensation equal
to 3.0% of the gross proceeds from the sale of all shares of common stock sold
through it as Agent under the Sales Agreement. Actual sales will depend on a
variety of factors to be determined by the Company from time to time, including,
among other things, market conditions, the trading price of the common stock,
capital needs and determinations by the Company of the appropriate sources of
funding for the Company. We have not yet sold any shares of our common stock
pursuant to the Sales Agreement.

As of September 30, 2022, we had cash, cash equivalents and marketable
securities, excluding restricted cash, of $169.2 million. We believe that our
existing cash, cash equivalents and marketable securities will be sufficient to
fund our planned operations into mid-2025.

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
arrangements 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.

Net Cash Used in Operating Activities


Net cash used in operating activities was $44.9 million for the nine months

of $3.1 million, amortization of premiums and discounts on marketable securities
of $2.6 million and stock-based compensation of $7.2 million. Net cash used in
operating activities was $43.8 million for the nine months ended
September 30, 2021, which was primarily due to our net loss of $52.5 million, an

payable, partially offset by non-cash charges for depreciation and amortization
of $3.1 million, amortization of premiums and discounts on marketable securities
of $2.0 million, stock-based compensation of $7.8 million and $1.1 million
higher accrued liabilities and deferred rent.

Net Cash Provided by Investing Activities



Net cash provided by investing activities for the nine months ended

from marketable securities of $64.8 million, partially offset by purchases of
property and equipment of $1.3 million. Net cash provided by investing
activities for the nine months ended September 30, 2021 was $47.6 million, which

partially offset by purchases of property and equipment of $1.5 million.

Net Cash Provided by (Used in) Financing Activities



Net cash provided by financing activities was $0.1 million for the nine months
ended September 30, 2022, which was due to the exercise of stock options and

in financing activities was $3.4 million for the nine months ended
September 30, 2021, which consisted primarily of payments related to a term

Contractual Obligations and Commitments



There have been no material changes to our contractual obligations during the
nine months ended September 30, 2022, as compared to those disclosed in our 2021
Annual Report.

Critical Accounting Policies, Significant Judgments and Use of Estimates



Our condensed financial statements have been prepared in accordance with U.S.
generally accepted accounting principles, or "GAAP". The preparation of our
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.

During the nine months ended September 30, 2022, there were no material changes to our critical accounting policies reported in our 2021 Annual Report.

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 SEC.

Recent Accounting Pronouncements



See Note 2 to our unaudited condensed financial statements included elsewhere in
this Quarterly Report for a discussion of recent accounting pronouncements that
may impact our financial position and results of operations.

Emerging Growth Company Status



As an emerging growth company, or "EGC", under the Jumpstart Our Business
Startups Act of 2012, or the "JOBS Act", we are eligible to take advantage of
certain exemptions from various reporting requirements that are applicable to
other public companies that are not EGCs. We have elected to take advantage of
the extended transition period for adopting new or revised accounting standards
that have different effective dates for public and private companies until such
time as those standards apply to private companies.
