Table of Contents

We caution readers not to place undue reliance on any forward-looking statements made by us, which speak only
as of the date of this Annual Report. We undertake no obligation to publicly update any forward-looking statements after
the  date  of  this  Annual  Report,  whether  as  a  result  of  new  information,  future  events  or  otherwise,  except  as  required
by law. We qualify all of our forward-looking statements by the foregoing cautionary statements.

RISK FACTOR SUMMARY

The following is a summary of the principal risk factors that make an investment in our common stock speculative
or  risky.  Before  you  invest  in  our  securities,  you  should  read  the  following  summary  together  with  the  more  detailed
description of material risks described under "Risk Factors" in Item 1A of this Annual Report and the other information
contained in this Annual Report.

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

● We  will  require  substantial  additional  financing  to  pursue  our  business  objectives,  which  may  not  be  available  on

acceptable terms, or at all.

Risks Related to the Discovery and Development of Our Product Candidates
● The impacts of the COVID-19 pandemic could continue to adversely affect our business.
● Our  business  is  dependent  on  our  ability  to  advance  our  current  and  future  product  candidates  through  preclinical

studies and clinical trials, marketing approval and ultimately commercialization, each of which is uncertain.

● Regulatory approval processes are lengthy and inherently unpredictable.
● Clinical development involves a lengthy and expensive process with uncertain outcomes, and as an organization we
have limited experience designing and implementing clinical trials. Failure to adequately design a trial, or incorrect
assumptions about the design of the trial, has resulted in delays in product development and could result in additional
costs, delays or the inability to develop, obtain regulatory approval for or commercialize our products.

● 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.

● Positive  results  from  preclinical  studies  and  early-stage  clinical  trials  may  not  be  predictive  of  future  results.  Initial

positive results may not be indicative of results obtained when the trial is completed or in later stage trials.

● We,  or  our  collaborators,  could  continue  to  encounter  difficulties  enrolling  patients  in  our  clinical  trials  due  to  the

COVID-19 pandemic or otherwise.

● Because the numbers of subjects in our Phase 1/2 clinical trials of NC318, NC410 and NC762 are small, the results

from each of these trials, once completed, may be less reliable than results achieved in larger clinical trials.

● Our current or future product candidates may cause undesirable side effects or have other properties that could halt
their  clinical  development,  delay  or  prevent  their  regulatory  approval,  limit  their  commercial  potential  or  result  in
significant negative consequences.

Risks Related to the Regulatory Approval and Commercialization of Product Candidates and Other Legal
Compliance Matters
● We may be unable to obtain regulatory approval of our product candidates. The denial or delay of any such approval

would prevent or delay commercialization of our product candidates and 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, and the market opportunities for any such product candidate may be limited.

● Development of product candidates, in combination with other therapies, exposes us to additional regulatory risks.
● We depend on data and our information technology systems, and any failure of these systems or any related security

breaches, loss of data, or other disruptions could harm our business.

Risks Related to Manufacturing
● Given  our  limited  operating  history,  our  manufacturing  experience,  as  an  organization  and  with  our  manufacturing
facility, is limited. We are subject to multiple manufacturing risks, any of which could substantially increase our costs
and limit supply of our product candidates.

4

Table of Contents

● 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.

● 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.

● We depend on third-party suppliers for key materials used in our manufacturing process, and the loss of these third-

party suppliers or their inability to supply us with adequate materials could 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,  or  if  the  scope  of  the  patent  protection  obtained  is  not
sufficiently  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  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.

● 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.

● We may not be able to protect our intellectual property rights throughout the world.
● We may be subject to claims, or we may become involved in lawsuits to protect or enforce our intellectual property,
which  could  be  expensive,  time-consuming  and  unsuccessful;  our  intellectual  property  could  be  found  invalid  or
unenforceable.

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. 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 our product candidates.

● We may depend on 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.

● 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.

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  face  significant  competition  from  other  biotechnology  and  pharmaceutical  companies,  and  our  operating  results

will suffer if we fail to compete effectively.

● We will need to grow the size of our organization, and we may experience difficulties in managing this growth.
● If we are unable to establish marketing, sales and distribution capabilities for any product candidate that may receive

regulatory approval, we may not be successful in commercializing those product candidates.

Risks Related to Our Common Stock
● The price of our common stock has been and may in the future be volatile and fluctuate substantially.
● We  are  now  and  may  in  the  future  be  subject  to  securities  litigation,  which  can  be  expensive  and  could  divert

management's attention.

● If securities analysts do not publish research or reports about our business or if they publish inaccurate or unfavorable

research about our business, the price of our stock could decline.

● 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.

Item 1. Business

PART I

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.

Our  lead  product  candidate,  NC318,  is  a  first-in-class  immunomedicine  against  a  novel  immunomodulatory
protein  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.

We began enrolling patients in the Phase 2 portion of the Phase 1/2 clinical trial of NC318 in October 2019. In this
portion, we planned to enroll up to 100 patients with tumor types that have been shown to have elevated S15 expression,
including non-small cell lung cancer, or “NSCLC”, ovarian cancer, head and neck squamous cell carcinoma, or “HNSCC”,
and triple-negative breast cancer, or “TNBC”.

We  have  modified  the  Phase  2  portion  of  the  trial  for  S15  selection,  whereby  clinical  sites  can  select  for  S15-
positive  patients  through  screening  biopsies  in  a  Clinical  Laboratory  Improvement  Amendments  (“CLIA”)-certified
laboratory.  In  the  second  quarter  of  2021,  we  revised  the  dosing  regimen  to  800  mg  weekly  to  increase  overall  drug
exposure  to  NC318.  We  provided  a  data  update  from  our  ongoing  monotherapy  trial  of  NC318  at  the  SITC  Meeting  in
November  2021.  Based  on  combined  Phase  1  and  Phase  2  data  from  the  NC318  study,  NC318  continued  to  show  early
evidence of possible clinical benefit in patients with HNSCC, lung and breast cancer and other advanced/metastatic solid
tumors, with dosing once every two weeks during dose escalation and a dose of 400 mg selected for the Phase 2 studies.
NC318 continued to be well-tolerated in the Phase 2 portion of the trial, with primarily mild or moderate treatment-related
adverse events, or “TRAE”. We expect to provide further data from the Phase 2 portion of this trial in the fourth quarter of
2022.

In April 2021, Yale University commenced a Phase 2 investigator-initiated clinical trial of NC318 in combination

with pembrolizumab in patients with NSCLC. Initial data are anticipated in the second half of 2022.

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,  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 is designed to evaluate the safety and tolerability of NC410 and determine
its pharmacologically active and/or maximum tolerated dose. Interim data presented from the Phase 1 dose-escalation study
show that NC410 appears to be safe and well-tolerated in patients with advanced tumors and shows evidence of immune
modulation. We expect to provide further data from the Phase 1 portion of this trial in the second half of 2022.

Our  third  product  candidate,  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  potentially  other  tumor  types.  The  Phase  1  dose-escalation  portion  of  this
open-label  trial  is  being  designed  to  evaluate  the  safety  and  tolerability  of  NC762  and  determine  its  pharmacologically
active  and/or  maximum  tolerated  dose.  We  expect  to  announce  initial  data  from  the  Phase  1  portion  of  this  trial  in  the
second half of 2022.

Our  fourth  product  candidate,  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

6

Table of Contents

cells and LSCs while sparing hematopoietic stem and progenitor cells, or “HSPCs”. Preclinical data were presented at the
American  Society  for  Hematology  annual  meeting,  or  the  “ASH  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, or
“CDX”,  animal  model  in  vivo  and  (iii)  restricts  AML  progression  in  patient-derived  xenografts,  or  “PDX”,  in  vivo.  An
IND submission is planned for the fourth quarter of 2022.

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  and  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  seek  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.  The  immunosuppressive  properties  of  S15,  the  target  of  NC318,  were  discovered  using  a
predecessor of our FIND-IO platform.

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.

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, NC410 and NC762. We began
enrolling  patients  in  the  Phase  2  portion  of  the  Phase  1/2  clinical  trial  evaluating  NC318  in  patients  with
advanced  or  metastatic  tumors  in  October  2019.  In  addition,  we  believe  scientific  evidence  supports  a
combination of NC318 with anti-PD-1 therapy, and Yale commenced a Phase 2 investigator-initiated clinical
trial  of  NC318  in  combination  with  pembrolizumab  in  patients  with  NSCLC.  For  NC410,  we  initiated  the
Phase 1 portion of a Phase 1/2 clinical trial in June 2020 and reported preclinical data demonstrating that

7

Table of Contents

NC410 promoted T-cell mediated anti-tumor immunity, enhanced infiltration and increased localized activity
of T-cells in the TME. For NC762, we initiated a Phase 1/2 clinical trial in patients with lung cancer, breast
cancer, ovarian cancer or potentially other tumor types in July 2021.

● Building an oncology pipeline of novel targets for new immunomedicines focused on non-responders. We
are continuing to leverage our immunological expertise and our FIND-IO platform to identify novel targets
relevant to overcoming immune suppression.

● Leveraging our fully integrated development, quality systems and cGMP manufacturing capabilities. Our
approach is to integrate key aspects of product development within our organization. We have assembled a
team  with  extensive  experience  in  identifying,  characterizing  and  developing  novel  immunomedicines.  We
seek to couple discovery of important targets with the capability to rapidly streamline target validation and
conduct  key  IND-enabling  studies,  leading  to  clinical  development  of  lead  candidates.  Our  purpose-built,
to  support
dedicated,  state-of-the-art  cGMP  manufacturing  facility  utilizes  single-use 
development  of  our  pipeline  and  advancement  of  our  product  candidates  into  and  through  clinical
development.  The  facility  has  production  capacity  of  2,000  liters  and  is  designed  to  operate  as  a  multi-
product facility. Compared to working with third-party manufacturers, we believe our facility provides better
quality  assurance,  greater  control  in  scheduling  and  prioritizing  manufacturing  activities  and  enhanced
capital efficiency.

technology 

● Expanding  our  current  focus  and  creating  new  opportunities  outside  of  the  oncology  field.  While  our
primary  focus  is  oncology,  the  functional  screening  approach  and  proprietary  technology  of  our  FIND-IO
platform  are  broadly  applicable  to  the  identification  of  positive  and  negative  immune  modulators,  and
therefore can be used and expanded to discover novel targets in other inflammatory diseases. Our goal is to
enable  next-generation  immunomedicines  for  other  serious  inflammatory  diseases  with  significant  unmet
medical needs in fields beyond oncology.

● Extending the reach of our product candidates through strategic partnerships and collaborations. We have
exclusive  worldwide  rights  to  our  current  product  candidates  and  our  FIND-IO  platform.  We  expect  to
explore  a  variety  of  market  opportunities  for  our  current  and  future  product  candidates  and  our  platforms,
including  through  the  pursuit  of  strategic  partnerships  or  other  collaborations  with  regard  to  selected
indications or geographical areas, such as Asia. We intend for our product candidates to be developed and
commercialized  globally,  by  us  in  key  markets  and  in  collaboration  with  other  companies  for  other
geographies.

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.

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  based  on  the  belief  that  an  immune  system
inactivated  by  co-inhibitory  proteins,  known  as  checkpoints,  could  be  reactivated  to  recognize  and  attack  the  tumor.
Therapies against checkpoints, such as PD-L1, PD-1 and Cytotoxic T-Lymphocyte Antigen, or “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, it is estimated that up to 60% to 70% of cancer patients do not
respond to single-agent therapy with 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 T-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
“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, and NC410 targets the negative signaling from 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.

Expanding Targets Beyond T-Cells

NC318

Our Programs

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 the Phase 1 portion of our Phase 1/2 clinical
trial of NC318 in patients with advanced or metastatic solid tumors, we began enrolling patients in the Phase 2 portion of
the trial in October 2019. The Phase 2 portion of the trial was designed as a Simon Two-Stage trial, a type of Phase 2 trial
that is multi-stage and is conducted in two stages with the option to stop the trial after the first stage or after the second
stage.

We  have  modified  the  Phase  2  portion  of  the  trial  for  S15  selection,  whereby  clinical  sites  can  select  for  S15-
positive patients through screening biopsies in a CLIA-certified laboratory. In the second quarter of 2021, we revised the
dosing  regimen  to  800  mg  weekly  to  increase  overall  drug  exposure  to  NC318.  We  provided  a  data  update  from  our
ongoing monotherapy trial of NC318 at the SITC Meeting in November 2021. Based on combined Phase 1 and Phase 2
data from the NC318 study, NC318 continued to show early evidence of possible clinical benefit in patients with HNSCC,
lung  and  breast  cancer  and  other  advanced/metastatic  solid  tumors,  with  dosing  once  every  two  weeks  during  dose
escalation  and  a  dose  of  400  mg  selected  for  the  Phase  2  studies.  NC318  continued  to  be  well-tolerated  in  the  Phase  2
portion of the trial, with primarily mild or moderate TRAE. We have exclusive worldwide rights to NC318.

In April 2021, Yale University commenced a Phase 2 investigator-initiated clinical trial of NC318 in combination

with pembrolizumab in patients with NSCLC.

S15 Background

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

10

Table of Contents

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 T-cell signaling on immune cells. Several Siglecs play key roles in
helping immune cells distinguish between self, and non-self and modulating immune responses. 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-1β and TNF-α, 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

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

Phase 1/2 Clinical Trial

In October 2018, we initiated the Phase 1 portion of a Phase 1/2 clinical trial to evaluate NC318 as a monotherapy
in patients with advanced or metastatic solid tumors. This ongoing 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.

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 dosed 49 patients across seven dose cohorts: 8 mg, 24 mg, 80 mg, 240 mg, 400 mg, 800 mg
and 1,600 mg, the last of which was added to the trial because a maximum tolerated dose had not been reached through 800
mg. The most common tumors in the Phase 1 portion of the Phase 1/2 trial were NSCLC (13 patients), ovarian (7 patients),
melanoma  (7  patients),  breast  (4  patients)  and  colorectal  (3  patients).  Enrolled  patients  had  all  been  subject  to  previous
cancer treatments, with a median of three prior therapies, and all 13 NSCLC patients were PD-1 refractory and had been
treated with a median of four prior therapies.

Preliminary  data  from  the  Phase  1  portion  were  presented  in  November  2019  at  the  SITC  annual  meeting  and
updated data were announced in December 2020. As of December 17, 2020, NC318 had been well-tolerated in the Phase 1
portion of the trial and only one dose-limiting toxicity, a grade 3 pneumonitis at the highest dose level, had been observed.
Treatment-related adverse events experienced by more than 5% of patients as of that date were diarrhea, infusion reactions,
fatigue,  headaches,  pruritis,  elevated  amylase  and  elevated  lipase.  Most  treatment-related  adverse  events  were  easily
manageable, asymptomatic or mild or moderate, with the exception of one case of grade 3 episcleritis/uveitis at the 400 mg
dose level that resolved after steroid therapy and two cases of grade 3 pneumonitis (one at the 400 mg dose level and one at
the 1,600 mg dose level). We also observed two grade 1 cases of vitiligo (one at the 80 mg dose level and one at the 400
mg  dose  level)  that,  along  with  other  immune-related  adverse  events  including  diarrhea,  elevated  amylase  and  lipase,
pruritis, episcleritis/uveitis and pneumonitis, indicate NC318’s activity as a modulator of the immune system.

Data  from  the  Phase  1  portion  of  the  trial  indicate  activity  in  multiple  tumor  types,  including  durable  stable
disease in patients with NSCLC, endometrial cell cancer, ovarian cancer, squamous cell carcinoma, Merkel cell cancer, and
head  and  neck  cancer.  As  of  December  17,  2020,  durable  responses  observed  include  one  complete  response,  which
remained

12

Table of Contents

ongoing at 104 weeks, and one partial response, which remained ongoing at 78 weeks, both in NSCLC patients, as well as
10 patients with stable disease, which remained ongoing for six months or more. The patient with the complete response
had multiple lesions prior to treatment with NC318, including two lesions that were at least 10 mm. Among the 10 patients
with stable disease, four patients have NSCLC with stable disease for six months or more.

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 planned to enroll up to 100 patients with
tumor types that have been shown to have elevated S15 expression, including NSCLC, ovarian cancer, HNSCC and TNBC.
In the Phase 2 portion, patients were initially selected based on tumors with a PD-L1 TPS of less than 50%. S15 expression
was  analyzed  retrospectively  in  all  pretreatment  biopsies  successfully  obtained  from  the  Phase  2  patients.  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.

In July 2020, we reported a confirmed partial response in a HNSCC patient. In addition, we reported that at that
time  we  would  not  progress  the  NSCLC  and  ovarian  cancer  cohorts  to  the  second  stage  of  the  Simon  2-stage  trial.  In
December  2020,  we  completed  a  retrospective  analysis  of  S15  expression  in  biopsy  samples  collected  from  the  Phase  2
patients  at  their  initial  screening.  During  initial  screenings,  we  did  not  have  an  available  screening  assay  to  select  for
patients based on S15-positive biopsies. Therefore, inclusion criterion was based on a TPS PD-L1 score <50%, given the
non-overlapping expression of S15 and PD-L1. Of the evaluable biopsies collected, retrospective analysis showed that 13%
of the patients enrolled had S15-positive tumors. These biopsies showed that the selection criterion, based on low PD-L1
expression,  did  not  result  in  enough  S15-positive  patients  for  us  to  effectively  evaluate  the  activity  of  NC318  in  S15-
positive tumors.

We  have  modified  the  Phase  2  portion  of  the  trial  for  S15  selection,  whereby  clinical  sites  can  select  for  S15-
positive  patients  through  screening  biopsies  in  a  CLIA-certified  laboratory.  In  the  second  quarter  of  2021,  we  resumed
enrolling a NSCLC adenocarcinoma cohort in the Phase 2 trial, and we revised the dosing regimen to 800 mg weekly to
increase  overall  drug  exposure  to  NC318.  We  provided  a  data  update  from  our  NC318  monotherapy  trial  at  the  SITC
meeting  in  November  2021.  Based  on  combined  Phase  1  and  Phase  2  data  from  the  NC318  study,  NC318  continued  to
show  early  evidence  of  possible  clinical  benefit  in  patients  with  HNSCC,  lung  and  breast  cancer  and  other
advanced/metastatic solid tumors, with dosing once every two weeks during dose escalation and a dose of 400mg selected
for the Phase 2 studies. NC318 continued to be well-tolerated in the Phase 2 portion of the trial, with primarily mild or
moderate TRAE. The only observed severe or higher-grade TRAE in the Phase 2 portion was a grade 3-4 infusion reaction
in one patient. Pharmacokinetic and pharmacodynamic modeling using serum samples from the Phase1/2 trial, predicted
that a dose of 800 mg once a week results in nearly ten times greater drug exposure which may impact drug activity and
clinical outcomes. This led to the decision to revise the dosing regimen to 800 mg weekly.

Phase 2 Combination Clinical Trial

In April 2021, Yale University commenced a Phase 2 investigator-initiated clinical trial of NC318 in combination

with pembrolizumab in patients with NSCLC.

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 have exclusive worldwide rights to NC410.

Background of LAIR Pathway in Cancer

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.

13

Table of Contents

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

Our Clinical Development Plan for NC410

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 have conducted expansive screening efforts on tumor samples from different solid tumor types
to identify tumors that express LAIR-1 on immune cells and varying levels of collagen in the TME, to guide our ultimate

14

Table of Contents

selection of patients for the Phase 2 portion of the Phase 1/2 clinical trial. We plan to develop a CLIA-certified assay to
select patients for the Phase 2 study.

In June 2020, we initiated a Phase 1/2 clinical trial of NC410 in patients with advanced or metastatic solid tumors
after  a  temporary  delay  due  to  the  COVID-19  pandemic.  The  Phase  1  dose-escalation  portion  of  this  open-label  trial  is
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. After a recommended dose for the Phase 2 portion
of  the  trial  is  determined,  the  efficacy  of  NC410  will  be  evaluated  in  select  tumor  types.  In  May  2021,  at  the  ASCO
Meeting, we reported preclinical data demonstrating that NC410 promoted T-cell mediated anti-tumor immunity, enhanced
infiltration and increased localized activity of T-cells in the TME. We provided a data update from the Phase 1 portion of
this trial at the SITC Meeting in November 2021. Interim data presented from the Phase 1 dose-escalation study show that
NC410 appears to be safe and well-tolerated in patients with advanced tumors and show evidence of immune modulation.
Safety, tolerability, efficacy and biomarker analyses are ongoing in higher-dose cohort patients.

NC762

NC762 is a monoclonal antibody that binds specifically to human B7 homolog 4 protein, or “B7-H4”, a protein
expressed on multiple tumor types. We believe NC762 acts by inhibiting tumor cell growth. While the inhibitory effect on
tumor growth does not appear to be dependent upon T-cells, we believe NK cells may contribute to enhanced anti-tumor
activity mediated by NC762. We have observed in preclinical studies that NC762 inhibits the growth of human melanoma
tumors  in  mice,  and  we  believe  that  NC762  has  the  potential  to  treat  multiple  tumor  types.  In  July  2021,  we  initiated  a
Phase  1/2  clinical  trial  of  NC762  in  patients  with  lung  cancer,  breast  cancer,  ovarian  cancer,  or  potentially  other  tumor
types. The Phase 1 dose-escalation portion of this open-label trial is being designed to evaluate the safety and tolerability of
NC762  and  determine  its  pharmacologically  active  and/or  maximum  tolerated  dose.  After  a  recommended  dose  for  the
Phase 2 portion of the trial is determined, the efficacy of NC762 will be evaluated in select tumor types. We have exclusive
worldwide rights to NC762.

B7-H4 Background

B7-H4 is a cell surface protein expressed on multiple tumor types, including non-small cell lung cancer, ovarian
cancer, breast cancer and hepatocellular carcinoma, and on tumor-associated macrophages, and shows limited expression in
most  normal  tissues.  B7-H4  was  initially  discovered  in  2003  in  the  Mayo  Clinic  lab  of  our  scientific  co-founder  Dr.
Lieping Chen. It is a member of the same family of co-inhibitory checkpoint proteins as B7-H1, known as PD-L1, which
was also discovered by Dr. Chen's laboratory (see "Immuno-Oncology Background") B7-H4 has been shown in published
articles  to  negatively  regulate  T-cell  immune  response,  inhibit  cytokine  production,  suppress  antigen-presenting  cells,
promote immune escape and play a role in tumorigenesis and tumor development. Expression of B7-H4 in tumor cells has
been  shown  in  preclinical  research  and  published  articles  to  be  correlated  with  reduced  overall  survival,  and  B7-H4  has
generally non-overlapping expression with both PD-L1 and S15. Given the low expression of B7-H4 on healthy cells and
the  results  of  our  preclinical  cross-tissue  reactivity  studies,  we  believe  that  anti-B7-H4  treatment  is  unlikely  to
inadvertently  cause  adverse  effects  of  tissues  and  pathways  outside  of  B7-H4  positive  tumors  and  tumor-associated
macrophages.

NC762  is  a  novel  immunotherapeutic  protein  that  binds  to  B7-H4  on  the  cell  surface  of  tumors.  We  believe
NC762 acts by inhibiting tumor cell growth and killing tumor cells, including by enhancing immune response. Preclinical
research indicates that the primary mechanism of action of NC762 inhibits tumor cell growth independently of immune cell
infiltration  into  the  TME.  NC762  was  also  designed  to  enhance  immune  response  by  allowing  for  enhanced  binding  to
CD16a/FcγRIIIa, a receptor found on the surface of natural killer, or NK cells, in order to increase antibody-dependent T-
cell-mediated cytotoxicity, or “ADCC”, activity. ADCC is a process by which effector cells such as NK cells interact with
and  kill  antibody-coated  target  T-cells  such  as  tumor  cells.  Extensive  in  vivo  modeling  data  using  human  melanoma  in
mouse models expressing B7-H4 indicate that NC762's anti-tumor effect may be enhanced in the presence of NK cells, but
that it has an anti-tumor impact even in the absence of peripheral blood mononuclear cells (comprising several types of
white blood cells including NK cells), and that the primary mechanism by which NC762 inhibits tumor growth is therefore
ADCC-independent.

15

Table of Contents

Preclinical studies did not raise any significant safety concerns with NC762. Specifically, dosage of cynomolgus
monkeys  at  doses  up  to  100  mg/kg  did  not  result  in  any  observed  adverse  effects.  A  tissue  cross-reactivity  study  of  37
tissues from three individuals found no signals that NC762 binds to tissues other than tumor tissue, which indicates that
NC762 is not expected to bind off target and harm cells, tissues and pathways outside of B7-H4 positive tumors and tumor-
associated macrophages. In addition, an analysis of changes in serum cytokines in vitro leads us to believe that treatment
with NC762 is unlikely to trigger overactive immune responses known as cytokine storms that can have harmful effects.

We have developed an IHC assay using a commercially purchased antibody to test tumors for B7-H4 positivity
and have performed screening of multiple tumor types. We intend to use this assay to select patients for treatment through
patient biopsies, including in the Phase 1 dose expansion portion of our planned Phase 1/2 clinical trial, and have validated
the assay for use in clinical trials. We also intend to retroactively use immunophenotyping and serum analysis as part of our
clinical  trials  to  determine  the  types  of  cells  present  after  treatment  in  order  to  identify  biomarkers,  to  look  for  signs  of
clinical activity, and to help determine the likelihood of responsiveness to treatment with NC762.

Our Clinical Development Plan for NC762

We and others have observed that B7-H4 is widely expressed on a number of cancers, including non-small cell
lung cancer, ovarian cancer, breast cancer and hepatocellular carcinoma. These analyses support possible targeting of these
tumor  types  as  primary  indications  for  therapeutic  treatment  with  NC762.  Using  a  B7-H4-specific  antibody  that  we
identified and optimized for IHC analyses, we are currently staining various cancer tissues to gain a more comprehensive
and definitive understanding of B7-H4 prevalence in both primary and metastatic lesions.

In July 2021, we initiated a Phase 1/2 clinical trial of NC762 in patients with lung cancer, breast cancer, ovarian
cancer or potentially other tumor types. The Phase 1 dose-escalation portion of this open-label trial is being designed to
evaluate the safety and tolerability of NC762 and determine its pharmacologically active and/or maximum tolerated dose.
After a recommended dose for the Phase 2 portion of the trial is determined, the efficacy of NC762 will be evaluated in
select tumor types.

NC525

Our  fourth  product  candidate  NC525  is  a  novel  LAIR-1  antibody  that  selectively  targets  AML,  blast  cells  and
LSCs.  Preclinical  data  show  that  NC525  kills  AML  blast  cells  and  LSCs  while  sparing  HSPCs.  Preclinical  data  were
presented  at  the  ASH  Meeting  in  December  2021.  The  data  showed  that  NC525  (i)  inhibits  colony  formation  of  AML
LSCs in vitro, (ii) inhibits AML growth in the CDX, animal model in vivo and (iii) restricts AML progression in PDX, in
vivo. We have exclusive worldwide rights to NC525.

Our Research Programs

In addition to NC318, NC410, NC762 and NC525, we are also pursuing preclinical evaluation of other potential

novel immunomodulatory molecules.

Our FIND-IO Platform

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.

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, as well as in
neuro-inflammatory diseases.

Our Collaboration Agreements

Agreements with Yale University

License Agreement with Yale

We entered into a license agreement with Yale, or the Yale Agreement, in December 2015 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, and subsequently amended the Yale Agreement in January 2020 and October 2021. 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  as  a  result  of  research  under  the  corporate  sponsored  research
agreement  described  below,  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.

Sponsored Research Agreement with Yale

In  connection  with  the  Yale  Agreement,  we  also  entered  into  a  corporate  sponsored  research  agreement,  or
“SRA”,  with  Yale,  pursuant  to  which  we  had  agreed  to  provide  an  aggregate  of  up  to  $15  million  to  fund  a  research
program  aimed  at  discovering  new  targets  for  immunomedicines.  The  SRA  was  subsequently  amended  in  January  2020
and October 2021 and expired on December 31, 2021. We do not intend to renew the SRA.

Former Research and Development Collaboration with Lilly

Effective  March  3,  2020,  Eli  Lilly  and  Company,  or  Lilly,  terminated  the  multi-year  research  and  development
collaboration agreement, or the Lilly Agreement, without cause that we had entered into with Lilly in November 2018 and
that focused on the discovery and development of immunomedicines for oncology using our FIND-IO platform. Under the
agreement,  we  had  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.

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  a  production  capacity  of  2,000  liters  in  order  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 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  trials  of  NC318,  NC410,  and  NC762  and  intend  to  provide  the  drug  supply  for  future  clinical  trials  of  NC318,
NC410,  NC762  and  NC525.  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 December 31, 2021, our intellectual property portfolio
includes, on a worldwide basis, 20 pending foreign patent applications relating to NC318, NC410, NC762 and NC525, two
pending U.S. patent application relating to NC318, one pending U.S. patent application relating to NC410, two pending
U.S. patent applications relating to NC762, one U.S. patent application relating to NC525 and additional pending patent
applications for other discovery and research programs. Patents resulting from our patent applications for NC318, NC410
and NC525, if issued, are expected to expire beginning in 2037 absent any patent term adjustments or extensions and for
NC762, if issued, are expected to expire beginning in 2039 absent any patent term adjustments or extensions.

18

Table of Contents

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  among  other  things  patent  applications
relating to methods of use for S15 that covers the use of NC318 and one allowed patent relating to FIND-IO. 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
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.

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

19

Table of Contents

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:

● completion of non-clinical laboratory tests and animal studies performed in accordance with the FDA’s good

laboratory practice, or “GLP”, regulations;

● manufacture, labeling and distribution of investigational drug in compliance with cGMP;

● submission to the FDA of an IND application, which must become effective before clinical trials may begin

and must be updated annually or when significant changes are made;

● approval  by  an  independent  institutional  review  board,  or  “IRB”,  or  ethics  committee  at  each  clinical  site

before each clinical trial may be initiated;

● performance  of  adequate  and  well-controlled  human  clinical  trials  in  accordance  with  the  FDA’s  current
Good Clinical Practices requirements, or “cGCP”, to establish the safety, purity and potency of the proposed
biological product candidate for its intended purpose;

● preparation of and submission to the FDA of a biologics license application, or “BLA”, after completion of

all pivotal clinical trials requesting marketing approval for one or more proposed indications;

● obtain  satisfactory  completion  of  an  FDA  Advisory  Committee  review,  where  appropriate,  as  may  be

requested by the FDA to assist with its review;

● satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which
the proposed product, or certain components thereof, are produced to assess compliance with cGMP and data
integrity  requirements  to  assure  that  the  facilities,  methods  and  controls  are  adequate  to  preserve  the
biologic’s identity, safety, quality, purity and potency;

● satisfactory completion of FDA audits of selected clinical investigation sites to assure compliance with cGCP

requirements and the integrity of the clinical data;

● payment of user fees under the Prescription Drug User Fee Act for the relevant year;

● obtain  FDA  review  and  approval  of  the  BLA  to  permit  commercial  marketing  of  the  licensed  biologic  for

particular indications for use in the United States; and

● compliance  with  post-approval  requirements,  including  the  potential  requirements  to  implement  a  Risk
Evaluation  and  Mitigation  Strategy,  or  “REMS”,  adverse  event  and  biological  product  deviation  reporting
and to complete any post-approval studies.

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

20

Table of Contents

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.

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.

21

Table of Contents

Clinical Trials

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

● Phase 1: The investigational product is initially introduced into healthy human subjects or patients with the
target  disease  or  condition.  These  trials  are  designed  to  test  the  safety,  dosage  tolerance,  absorption,
metabolism  and  distribution  of  the  investigational  product  in  humans  and  the  side  effects  associated  with
increasing doses. These trials may also yield early evidence of effectiveness.

● Phase 2: The investigational product is administered to a limited patient population with a specified disease
or  condition  to  evaluate  the  preliminary  efficacy,  optimal  dosages  and  dosing  schedule  and  to  identify
possible  adverse  side  effects  and  safety  risks.  Multiple  Phase  2  clinical  trials  may  be  conducted  to  obtain
information prior to beginning larger and more expensive Phase 3 clinical trials.

● Phase  3:  The  investigational  product  is  administered  to  an  expanded  patient  population  to  further  evaluate
dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally
at multiple geographically dispersed clinical trial sites. These clinical trials are intended to generate sufficient
data  to  statistically  evaluate  the  efficacy  and  safety  of  the  product  for  approval,  to  establish  the  overall
risk/benefit ratio of the investigational product and to provide an adequate basis for product approval by the
FDA.

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 cost
of  preparing  and  submitting  a  BLA  is  substantial.  The  submission  of  most  BLAs  is  additionally  subject  to  a  substantial
application  user  fee,  currently  exceeding  $2.8  million  for  fiscal  year  2021,  and  the  manufacturer  and  sponsor  under  an
approved BLA are also subject to annual program fees, currently $336,432 for each prescription product. These fees are
typically increased annually.

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 the FDA’s 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
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

23

Table of Contents

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.

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. Biologic manufacturers and their third-party contractors are required to register their
facilities  with  the  FDA  and  certain  state  agencies.  These  facilities  are  subject  to  routine  and  periodic  unannounced
inspections  by  the  FDA  and  certain  state  agencies  for  compliance  with  cGMP,  post-marketing  safety  reporting  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.

24

Table of Contents

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:

● restrictions  on  the  marketing  or  manufacturing  of  a  product,  complete  withdrawal  of  the  product  from  the

market or product recalls;

● fines, Warning Letters, Untitled Letters or holds on post-approval clinical studies;

● refusal of the FDA to approve pending applications or supplements to approved applications, or suspension

or revocation of existing product approvals;

● product seizure or detention, or refusal of the FDA to permit the import or export of products or Import Alert;

or

● permanent injunctions and consent decrees, including the imposition of civil or criminal penalties.

The FDA strictly regulates the marketing, labeling, advertising and promotion of prescription drug and biological
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,  administrative,  and  criminal  fines,
penalties,  and  agreements  that  materially  restrict  the  manner  in  which  a  company  promotes  or  distributes  products.  The
federal government has levied large civil, administrative, and criminal fines and penalties 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 biological products 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 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

25

Table of Contents

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 biological product. A
biological  product  on  which  another  biological  product  candidate’s  BLA  relies  to  establish  biosimilarity  is  known  as  a
reference 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. 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.  On  December  20,  2019,
President  Trump  signed  into  law  H.R.  1865,  the  Further  Consolidated  Appropriations  Act  of  2020.  The  law  includes
significant provisions related to the Trump Administration’s biosimilars policy framework and FDA’s implementation of
the BPCIA, such as clarifying that “chemically synthesized polypeptides” are no longer excluded from being regulated as
biologics, while “peptides” (polymers composed of 40 or fewer amino acids) will continue to be regulated as drugs unless
they  otherwise  meet  the  statutory  definition  of  biological  products.  In  addition,  the  Further  Consolidated  Appropriations
Act of 2020 clarifies exclusivity and procedural issues related to certain biologics approved as drugs pursuant to new drug
applications, or “NDAs”, to be the subject of an approved BLA, or transition biological products. The law also incorporates
provisions  intended  to  reduce  price  and  increase  competitiveness  in  the  pharmaceutical  industry.  The  law  amends  the
FDCA to create a private right of action against NDA or BLA holders that refuse to provide sufficient quantities of samples
of  an  approved  reference  product  to  generic  and  biosimilar  developers.  In  July  2018,  the  FDA  released  its  Biosimilars
Action  Plan  to  improve  the  efficiency  of  the  biosimilar  and  interchangeable  product  development  and  approval  process.
The  Further  Consolidated  Appropriations  Act  of  2020  is  consistent  with  FDA  guidance  documents  issued  in  December
2018  that  were  intended  to  advance  the  agency’s  biosimilars  policy  framework.  The  implementation  of  the  Further
Consolidated Appropriations Act of 2020 and the ultimate impact of the agency’s Biosimilars Action Plan are uncertain
and may evolve over time through future laws and regulations and guidance provided by regulatory and governing bodies.
In  addition,  other  aspects  of  the  BPCIA,  some  of  which  may  impact  the  BPCIA  exclusivity  provisions,  have  been  the
subject of recent litigation.

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  complementary  diagnostic  test  such  as  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 post-market 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.

27

Table of Contents

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

Pharmaceutical Coverage and Reimbursement

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. Though we expect our initial product offering to be covered under
Medicare Part B and thus not subject to Medicare Part D formulary requirements, private 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 related 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 processes 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  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.

Other U.S. Healthcare Laws and Compliance Requirements

In the United States, our business is 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:

● The federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting,
receiving,  offering  or  paying  any  remuneration  (including  any  kickback  or  bribe),  directly  or  indirectly,
overtly or covertly, in cash or in kind, to induce, or in return for, either the referral of an individual, or the
purchase, lease, order, arranging for or recommending the purchase, lease, or order of any item or service for
which  payment  may  be  made,  in  whole  or  in  part,  under  federal  healthcare  programs  like  Medicare  or
Medicaid.  A  person  or  entity  can  be  found  guilty  of  violating  the  statute  without  actual  knowledge  of  the
statute  or  specific  intent  to  violate  it.  The  federal  Anti-Kickback  Statute  has  been  interpreted  to  apply  to
arrangements  between  pharmaceutical  manufacturers  on  the  one  hand  and  prescribers,  purchasers,  and
formulary managers on the other, including, for example, consulting/speaking arrangements, discount and

28

Table of Contents

rebate offers, grants, charitable contributions, and patient support offerings, among others. A conviction for
violation of the federal Anti-Kickback Statute can result in criminal fines and/or imprisonment and requires
mandatory exclusion from participation in federal health care programs. Exclusion may also be imposed if
the government determines that an entity has committed acts that are prohibited by the federal Anti-Kickback
Statute. Although there are a number of statutory exceptions and regulatory safe harbors to the federal Anti-
Kickback  Statute  protecting  certain  common  business  arrangements  and  activities  from  prosecution  or
regulatory  sanctions,  the  exceptions  and  safe  harbors  are  drawn  narrowly,  and  practices  that  involve
remuneration  to  those  who  prescribe,  purchase,  or  recommend  pharmaceutical  and  biological  products,
including  certain  discounts,  or  engaging  such  individuals  as  speakers  or  consultants,  may  be  subject  to
scrutiny if they do not fit squarely within an exception or safe harbor. Our practices may not in all cases meet
all of the criteria for safe harbor protection from anti-kickback liability. Moreover, the Anti-Kickback Statute
safe harbors have been the subject of recent regulatory reforms. In late 2020, the U.S. Department of Health
and  Human  Services  Office  of  Inspector  General  issued  two  final  rules  finalizing  significant  safe  harbor
modifications  related  to  (1)  value-based  and  coordinated  care  arrangements  and  (2)  certain  point-of-sale
discounts and the existing discount safe harbor, or the “Rebate Rule”. Implementation of the Rebate Rule is
uncertain  due,  at  least  in  part,  to  ongoing  litigation  and  a  Congress-passed  moratorium  on  implementation
before January 1, 2026. We cannot predict the future of the Rebate Rule, the full impact of the Rebate Rule,
if  implemented,  or  subsequent  regulatory  actions  on  our  operations.  As  a  general  matter,  however,  any
changes to the safe harbors may impact our future contractual and other arrangements with pharmacy benefit
managers,  group  purchasing  organizations,  third-party  payors,  wholesalers  and  distributors,  healthcare
providers and prescribers, and other entities, as well as our future pricing strategies;

● The  federal  civil  and  criminal  false  claims  laws  and  civil  monetary  penalty  laws,  including  the  civil  False
Claims  Act,  or  “FCA”,  which  prohibits,  among  other  things:  (i)  knowingly  presenting,  or  causing  to  be
presented,  claims  for  payment  of  government  funds  that  are  false  or  fraudulent;  (ii)  knowingly  making,  or
using or causing to be made or used, a false record or statement material to a false or fraudulent claim; (iii)
knowingly making, using or causing to made or used a false record or statement material to an obligation to
pay  money  to  the  government;  or  (iv)  knowingly  concealing  or  knowingly  and  improperly  avoiding,
decreasing,  or  concealing  an  obligation  to  pay  money  to  the  federal  government.  Private  individuals,
commonly known as “whistleblowers,” can bring FCA qui tam actions, on behalf of the government and may
share in amounts paid by the entity to the government in recovery or settlement. Pharmaceutical companies
have been investigated and/or subject to government enforcement actions asserting liability under the FCA in
connection with their alleged off-label promotion of drugs, purportedly concealing price concessions in the
pricing  information  submitted  to  the  government  for  government  price  reporting  purposes,  and  allegedly
providing  free  product  to  customers  with  the  expectation  that  the  customers  would  bill  federal  healthcare
programs for the product. In addition, a claim including items or services resulting from a violation of the
federal  Anti-Kickback  Statute  constitutes  a  false  or  fraudulent  claim  for  purposes  of  the  FCA.  Moreover,
manufacturers can be held liable under the FCA even when they do not submit claims directly to government
payors if they are deemed to “cause” the submission of false or fraudulent claims. FCA liability is potentially
significant  in  the  healthcare  industry  because  the  statute  provides  for  treble  damages  and  significant
mandatory  penalties  per  false  or  fraudulent  claim  or  statement  for  violations.  Such  per-claim  penalties  are
currently set at $11,665 to $23,331 per false claim or statement for penalties assessed after June 19, 2020,
with respect to violations occurring after November 2, 2015. Criminal penalties, including imprisonment and
criminal fines, are also possible for making or presenting a false, fictitious or fraudulent claim to the federal
government;

● The federal Health Insurance Portability and Accountability Act of 1996, or “HIPAA”, which, among other
things,  prohibits  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any
healthcare  benefit  program,  including  private  third-party  payors,  and  prohibits  (i)  knowingly  and  willfully
falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent
statement  or  representation  and  (ii)  making  or  using  any  false  writing  or  document  knowing  the  same  to
contain any materially false, fictitious or fraudulent statement or entry in connection with the delivery of or
payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or
entity can be found guilty of violating the HIPAA fraud provisions without actual knowledge of the statute or
specific intent to violate it;

● HIPAA, the Health Information Technology for Economic and Clinical Health Act, or “HITECH Act”, and
implementing  regulations,  impose  requirements  relating  to  the  privacy,  security  and  transmission  of
individually  identifiable  health  information  held  by  covered  entities,  including  health  plans,  healthcare
clearinghouses  and  certain  healthcare  providers,  and  their  business  associates,  individuals  or  entities  that
perform  certain  services  on  behalf  of  a  covered  entity  that  involve  the  use  or  disclosure  of  individually
identifiable health information. HIPAA includes several tiers of civil monetary penalties as well as criminal
penalties. In addition, state attorneys general have authority to file civil actions for damages or injunctions in
federal  courts  to  enforce  HIPAA  and  seek  attorneys’  fees  and  costs  associated  with  pursuing  federal  civil
actions.  Research  institutions  that  we  collaborate  with  and  healthcare  providers  who  may  prescribe  our
products,  once  commercialized,  are  subject  to  privacy  and  security  requirements  under  HIPAA.  The
Department  of  Health  and  Human  Services  Office  for  Civil  Rights  (OCR)  has  recently  increased  its
enforcement efforts on compliance with HIPAA, including the security regulations (Security Rule), bringing
actions  against  entities  which  have  failed  to  implement  security  measures  sufficient  to  reduce  risks  to
electronic  protected  health  information  or  to  conduct  an  accurate  and  thorough  risk  analysis,  among  other
violations.  Although  we  are  not  directly  subject  to  HIPAA  other  than  with  respect  to  providing  certain
employee  benefits,  we  could  potentially  be  subject  to  criminal  penalties  if  we,  our  affiliates  or  our  agents
knowingly  obtain  or  disclose  individually  identifiable  health  information  maintained  by  a  HIPAA-covered
entity in a manner that is not authorized or permitted by HIPAA;

● Numerous  other  federal  and  state  laws  and  regulations  that  also  govern  the  privacy  and  security  of
individually  identifiable  health  information,  including  state  data  breach  notification  laws,  state  health
information or genetic privacy laws, and federal and state consumer protection laws such as Section 5 of the
Federal Trade Commission, or “FTC”, Act and the California Consumer Privacy Act, or “CCPA”. The CCPA
gives California residents expanded rights to access and delete their personal information, opt out of certain
personal information sharing and receive detailed information about how their personal information is used
by requiring covered companies to provide new disclosures to California consumers (as that term is broadly
defined)  and  provide  such  consumers  new  ways  to  opt-out  of  certain  sales  of  personal  information.  The
CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is
expected to increase data breach litigation. Although there are certain exemptions for personal information
subject  to  HIPAA  and  personal  data  collected  in  a  clinical  trial  context,  and  the  CCPA’s  implementation
standards and enforcement practices may increase our compliance costs and potential liability. Additionally, a
California ballot initiative, the California Privacy Rights Act, or “CPRA”, passed in November 2020, and the
majority  of  the  provisions  will  take  effect  on  January  1,  2023.  The  CPRA  will  impose  additional  data
protection  obligations  on  companies  doing  business  in  California,  including  additional  consumer  rights
processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses
of  sensitive  data.  It  also  created  a  new  California  data  protection  agency  authorized  to  issue  substantive
regulations  and  could  result  in  increased  privacy  and  information  security  enforcement.  Additional
compliance  investment  and  potential  business  process  changes  may  be  required.  Laws  similar  to  the
California  laws  have  passed  in  Virginia  and  Colorado,  and  comparable  laws  have  been  proposed  in  other
states  and  at  the  federal  level  that  may  ultimately  have  conflicting  requirements  that  would  further
complicate compliance. Meanwhile, the FTC has promulgated standards for fair information practices, which
concern consumer notice, choice, security and access, and also require notice of certain health information
breaches outside the HIPAA context. Consumer protection laws require us to publish statements that describe
how  we  handle  personal  information  and  choices  individuals  may  have  about  the  way  we  handle  their
personal  information.  Violating  consumers’  privacy  rights,  publishing  untrue  information  about  security
practices, or failing to take appropriate steps to keep consumers’ personal information secure may constitute
unfair  or  deceptive  acts  or  practices  in  violation  of  Section  5  of  the  FTC  Act.  Federal  regulators,  state
attorneys general and plaintiffs’ attorneys have been and will likely continue to be active in this space, and if
we do not comply with existing or new laws and regulations related to patient health information, we could
be subject to criminal or civil sanctions.

● In  addition,  some  countries  are  considering  or  have  passed  legislation  implementing  data  protection
requirements or requiring local storage and processing of data or similar requirements that could increase the
cost  and  complexity  of  research  activities.  These  laws  and  regulations,  as  well  as  any  associated  claims,
inquiries,  investigations  or  any  other  government  actions  may  lead  to  unfavorable  outcomes  including
increased compliance costs, delays or impediments in the development of new products, negative publicity,

30

Table of Contents

increased operating costs, diversion of management time and attention and remedies that harm our business,
including fines or demands or orders that we modify or cease existing business practices.

● The federal Physician Payments Sunshine Act, implemented as the Open Payments Program, which requires
manufacturers  of  drugs,  devices,  biologics  and  medical  supplies  for  which  payment  is  available  under
Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually
to  CMS  information  related  to  direct  or  indirect  payments  and  other  transfers  of  value  to  physicians  and
teaching hospitals, as well as ownership and investment interests held in a company by physicians and their
immediate  family  members.  Beginning  in  2022,  applicable  manufacturers  will  also  be  required  to  report
information regarding payments and transfers of value provided to physician assistants, nurse practitioners,
clinical nurse specialists, certified nurse anesthetists and certified nurse-midwives; and

● Analogous U.S. state and local laws and regulations, such as state anti-kickback and false claims laws, which
may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed
by  non-governmental  third-party  payors,  including  private  insurers;  state  laws  that  require  pharmaceutical
companies  to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant
compliance  guidance  promulgated  by  the  federal  government  or  otherwise  restrict  payments  that  may  be
made to healthcare providers; state laws that restrict the ability of manufacturers to offer co-pay support to
patients  for  certain  prescription  drugs;  state  laws  that  require  drug  manufacturers  to  report  information
related  to  clinical  trials,  or  information  related  to  payments  and  other  transfers  of  value  to  physicians  and
other  healthcare  providers  or  marketing  expenditures;  state  laws  that  require  drug  manufacturers  to  report
information  on  the  pricing  of  certain  drugs;  state  laws  and  local  ordinances  that  require  identification  or
licensing of sales representatives; and state laws governing the privacy and security of health information in
certain circumstances, many of which differ from each other in significant ways and often are not preempted
by HIPAA, thus complicating compliance efforts.

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.

Healthcare Reform

In the United States there have been and continue to be a number of healthcare-related legislative and regulatory
initiatives and reforms 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, and substantially changed the way healthcare is financed by both governmental and
private  insurers  and  significantly  impacted  the  U.S.  pharmaceutical  industry.  Among  other  things,  the  ACA:  subjects
biologics  to  potential  competition  by  lower-cost  biosimilars;  addresses  a  methodology  through  which  rebates  owed  by
manufacturers under the Medicaid Drug Rebate Program, or “MDRP”, are calculated for covered outpatient drugs that are
inhaled, infused, instilled, implanted or injected; increases the minimum Medicaid rebates owed by manufacturers under
the  MDRP  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 Medicare Part D coverage gap
discount program in which, as a condition of coverage of its products under Medicare Part D, manufacturers must agree to
offer point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage
gap period.

31

Table of Contents

The  ACA  and  certain  of  its  provisions  have  been  subject  to  judicial  challenges  as  well  as  legislative  and
regulatory efforts to repeal or replace them or to alter their interpretation or implementation. 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  that  repealed  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.”  The  Bipartisan  Budget  Act  of  2018,  among  other
things, amended the ACA to increase the point-of-sale discounts that manufacturers must agree to offer under the Medicare
Part  D  coverage  discount  program  from  50%  to  70%  off  negotiated  prices  of  applicable  brand  drugs  to  eligible
beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under
Medicare  Part  D.  CMS  rules  issued  in  2018  permit  further  collections  and  payments  to  and  from  certain  ACA-qualified
health  plans  and  health  insurance  issuers  under  the  ACA  risk  adjustment  program.  The  Further  Consolidated
Appropriations Act of 2020 fully repealed the ACA’s “Cadillac Tax” on certain high-cost employer-sponsored insurance
plans  and,  effective  in  2021,  the  annual  fee  imposed  on  certain  health  insurance  providers  based  on  market  share.  On
January 28, 2021, President Biden issued an Executive Order to initiate a special enrollment period from February 15, 2021
through  August  15,  2021  for  purposes  of  obtaining  health  insurance  coverage  through  the  ACA  marketplace.  The
Executive  Order  also  instructed  certain  governmental  agencies  to  review  and  reconsider  their  existing  policies  and  rules
that limit access to healthcare, including among others, policies that create barriers to obtaining access to health insurance
coverage through the ACA marketplaces. Most recently, on March 11, 2021, Congress enacted the American Rescue Plan
Act  of  2021,  which  included  among  its  provisions  a  sunset  of  the  ACA’s  cap  on  pharmaceutical  manufacturers’  rebate
liability under the Medicaid Drug Rebate Program. Under the ACA, manufacturers’ rebate liability was capped at 100% of
the  average  manufacturer  price  for  a  covered  outpatient  drug.  Effective  January  1,  2024,  manufacturers’  MDRP  rebate
liability will no longer be capped, potentially resulting in a manufacturer paying more in MDRP rebates than it receives on
the sale of certain covered outpatient drugs. The American Rescue Plan Act also temporarily increased premium tax credit
assistance for individuals eligible for subsidies under the ACA for 2021 and 2022 and removed the 400% federal poverty
level  limit  that  otherwise  applies  for  purposes  of  eligibility  to  receive  premium  tax  credits.  In  the  future,  there  may  be
additional  challenges  and/or  amendments  to  the  ACA.  It  remains  to  be  seen  precisely  what  any  new  legislation  will
provide,  when  or  if  it  will  be  enacted,  and  what  impact  it  will  have  on  the  availability  and  cost  of  healthcare  items  and
services, including drug products.

In  December  2018,  the  United  States  District  Court  for  the  Northern  District  of  Texas  ruled  that  the  individual
mandate is (i) unconstitutional as a result of the associated tax penalty being repealed by Congress as part of the Tax Act
and (ii) not severable from the rest of the ACA, and that as a result the entire ACA is invalid. On December 18, 2019, the
U.S.  Court  of  Appeals  for  the  Fifth  Circuit  affirmed  the  district  court’s  decision  that  the  individual  mandate  is
unconstitutional but remanded the case to the district court to reconsider the severability question. The Supreme Court of
the United States granted certiorari on March 2, 2020 and heard oral argument on November 10, 2020. On June 17, 2021,
the Supreme Court dismissed the lawsuit without ruling on the merits of the states’ constitutionality arguments.

Additionally,  there  has  been  increasing  legislative  and  enforcement  interest  in  the  United  States  with  respect  to
specialty drug pricing practices. Specifically, several recent U.S. Congressional inquiries and proposed and enacted pieces
of federal and state legislation and regulation have been designed to, among other things: bring more transparency to drug
pricing; reduce the cost of prescription drugs under government payor programs; review the relationship between pricing
and  manufacturer  patient  programs;  and  reform  government  program  reimbursement  methodologies  for  drugs.  For
example,  included  in  the  Consolidated  Appropriations  Act,  2021  were  several  drug  price  reporting  and  transparency
measures, such as a new requirement for certain Medicare plans to develop tools to display Medicare Part D prescription
drug benefit information in real time and for group and health insurance issuers to report information on pharmacy benefit
and drug costs to the Secretaries of the Departments of Health and Human Services, Labor and the Treasury. Policymakers
have  also  indicated  that  they  will  continue  to  seek  legislative  and  administrative  measures  to  control  drug  costs.  For
example,  on  July  9,  2021,  President  Biden  issued  an  Executive  Order  to  promote  competition  in  the  U.S.  economy  that
included  several  initiatives  addressing  prescription  drugs.  Among  other  provisions,  the  Executive  Order  stated  that  the
Biden  administration  will  “support  aggressive  legislative  reforms  that  would  lower  prescription  drugs,  including  by
allowing Medicare to negotiate drug prices, by imposing inflation caps, and through other related reforms.” In response to
the Executive Order, on September 9, 2021, the Department of Health and Human Services issued a Comprehensive Plan
for Addressing High Drug Prices that identified potential legislative policies and administrative tools that Congress and the
agency  can  pursue  in  order  to  make  drug  prices  more  affordable  and  equitable,  improve  and  promote  competition
throughout the prescription drug industry, and foster scientific innovation.

32

Table of Contents

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, in May 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.

Human Capital Resources

Our success depends upon our ability to retain and attract highly qualified management and technical personnel.
As  of  December  31,  2021,  we  had  87  full-time  employees,  with  61%  male  and  39%  female.  Our  workforce  represents
diverse racial and ethnic backgrounds with the following self-identified groups among our employees: 46% White, 25%
Asian, 20% Black/African American and 9% Hispanic/Latino.

We  consider  the  intellectual  capital  of  our  employees  to  be  an  essential  driver  of  our  business  and  key  to  our
future  prospects.  Recruiting  and  retaining  qualified  employees,  consultants  and  advisors  for  our  business,  including
scientific  and  technical  personnel,  is  critical  to  our  success,  and  competition  for  skilled  personnel  is  intense  and  the
turnover rate can be high in our industry. We have historically addressed the turnover we have encountered and grown our
headcount in support of our expanding pipeline of research programs and product candidates, but we continue to monitor
our turnover rate and the overall supply of skilled labor in the market. We also monitor our compensation programs closely
and  provide  what  we  consider  to  be  a  competitive  mix  of  compensation  and  benefits  for  our  employees,  as  well  as
participation  in  our  equity  programs.  None  of  our  employees  are  subject  to  a  collective  bargaining  agreement  or
represented by a trade or labor union.

Corporate Information and Access to SEC Reports

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. We make available, free
of charge, on our website at www.nextcure.com, our annual reports on Form 10-K, quarterly reports on Form 10-Q, current
reports  on  Form  8-K  and  any  amendments  to  such  reports  as  soon  as  reasonably  practicable  after  such  reports  are
electronically  filed  with,  or  furnished  to,  the  SEC.  The  contents  of  our  website  are  not  incorporated  into  this  Annual
Report.

Item 1A. 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 Annual Report, including our financial statements and the related
notes and the information described in the section entitled “Management’s Discussion and Analysis of Financial Condition

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 $69.4 million and $36.6 million for the years ended December
31,  2021  and  2020,  respectively.  As  of  December  31,  2021,  we  had  an  accumulated  deficit  of  $187.0  million.  We  have
funded our operations to date primarily with proceeds from public offerings of our common stock, private placements of
our  preferred  stock  and  upfront  fees  received  under  the  Lilly  Agreement,  which  was  terminated  effective  March  2020.
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 year to year. We anticipate that our expenses will increase substantially if, and as, we:

● continue  to  advance  the  preclinical  and  clinical  development  of  our  existing  product  candidates  and  our

research programs;

● leverage  our  FIND-IO  platform  to  advance  additional  product  candidates  into  preclinical  and  clinical

development;

● seek regulatory approvals for any product candidates that successfully complete clinical trials;

● expand our cGMP manufacturing capacity, including to provide drug supply for future clinical trials;

● hire additional clinical, quality control, regulatory, scientific and administrative personnel;

● expand our operational, financial and management systems and increase personnel, including to support our

clinical development, manufacturing and commercialization efforts and our operations as a public company;

● maintain, expand and protect our intellectual property portfolio;

● establish a marketing, sales, distribution and medical affairs infrastructure to commercialize any products for
which we may obtain marketing approval and commercialize, whether on our own or jointly with a partner;

● acquire or in-license other technologies or engage in strategic partnerships; and

● incur additional legal, accounting or other expenses in operating our business.

To become and remain profitable, we, whether on our own or jointly with 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.

34

Table of Contents

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
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  potential  future
collaborators’, success in:

● completing preclinical studies and clinical trials of our product candidates, including our ongoing Phase 1/2

clinical trials for NC318, NC410 and NC762;

● seeking and obtaining marketing approvals for any product candidates that we or our collaborators develop;

● receiving acceptance of INDs for future product candidates;

● identifying and developing new product candidates;

● launching and commercializing product candidates for which we obtain marketing approval by establishing a
marketing,  sales,  distribution  and  medical  affairs  infrastructure  or,  alternatively,  collaborating  with  a
commercialization partner;

● achieving coverage and adequate reimbursement by hospitals and third-party payors, including governmental
authorities,  such  as  Medicare  and  Medicaid,  private  insurers  and  managed  care  organizations,  for  product
candidates, if approved, that we or our collaborators develop;

● manufacturing cGMP supply of our product candidates for clinical trials and, if approved, commercial sales;

● obtaining market acceptance of product candidates, if approved, that we develop as viable treatment options;

● addressing any competing technological and market developments;

● negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter

and performing our obligations under such arrangements;

● maintaining,  protecting  and  expanding  our  portfolio  of  intellectual  property  rights,  including  patents,  trade

secrets and know-how;

● defending against third-party interference or infringement claims, if any; and

● attracting, hiring and retaining qualified personnel.

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.

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, NC410, NC762 or NC525, 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

35

Table of Contents

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:

● the scope, progress, timing, results and costs of researching and developing NC318, NC410, NC762, NC525
and  our  other  product  candidates,  including  targets  identified  through  our  FIND-IO  platform,  and  of
conducting preclinical studies and clinical trials;

● the timing of, and the costs involved in, obtaining marketing approval for NC318, NC410, NC762, NC525

and any future product candidates we develop, if clinical trials are successful;

● the costs of manufacturing NC318, NC410, NC762, NC525 and any future product candidates for preclinical

studies and clinical trials and in preparation for marketing approval and commercialization;

● the  costs  of  commercialization  activities,  including  marketing,  sales  and  distribution  costs,  for  NC318,
NC410, NC762, NC525 and any future product candidates we develop, whether alone or with a collaborator,
if any of these product candidates are approved for sale;

● our ability to establish and maintain additional strategic collaborations, licensing or other arrangements on

favorable terms, if at all;

● the costs involved in preparing, filing, prosecuting, maintaining, expanding, defending and enforcing patent

claims, including litigation costs and the outcome of any such litigation;

● our current collaboration and license agreements remaining in effect and our achievement of milestones and
the timing and amount of milestone payments we are required to make, or that we may be eligible to receive,
under those agreements;

● the timing, receipt and amount of sales of, or royalties on, our future products, if any; and

● the emergence of competing therapies and other developments in the oncology market.

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  December  31,  2021,  we  had  $219.6  million  in  cash,  cash  equivalents  (excluding  restricted  cash)  and  marketable
securities. Based on our research and development plans, we expect that our existing cash, cash equivalents and marketable
securities will enable us to fund our operating expenses and capital expenditure requirements into the first quarter of 2024.
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 that are within or 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, research programs or 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  the  sale  of  common  stock  or  securities  convertible  or  exchangeable  into  common  stock,  your
ownership  interest  will  be  diluted.  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

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. For example, in December 2020, we announced that the initial
selection  criterion  for  our  Phase  1/2  trial  in  NC318  did  not  result  in  enough  S15-positive  patients  for  us  to  effectively
evaluate the activity of NC318 in S15-positive tumors, and that as a result we are modifying the Phase 2 portion of the trial
for S15 selection. Also, in our NC318 trial, we are continuing to evaluate alternate doses and dose administration schedules
depending  on  pharmacokinetics,  pharmacodynamics,  biomarker  data,  safety  results  and  feedback  from  investigators.  A
clinical  trial  that  is  not  well  designed  may  delay  or  prevent  initiation  or  completion  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. If we select an incorrect dose or dose administration schedule,
that  could  negatively  impact  the  results  of  the  trial,  including  if  we  select  doses  that  are  too  low  to  be  effective  or
administer doses too infrequently based on the half-life of the active ingredient. 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,  NC762,
NC525 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,  NC762,  NC525  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,  NC762,  NC525  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.

The impacts of the COVID-19 pandemic could continue to adversely affect our business.

In March 2020, the World Health Organization declared the 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. The impacts of COVID-19 initially placed significant strain on our clinical trial sites, raised concerns
around monitoring patient safety, slowed patient enrollment and caused delays in our clinical trials and issuance of results.
Any rise of COVID-19 infection rates, especially in the United States, could continue to negatively affect our clinical trial
going forward. We are continuing to work closely with our clinical partners and have taken steps as necessary to adjust our
protocols  and  timelines  due  to  the  impact  of  the  COVID-19  pandemic.  The  impacts  of  the  COVID-19  pandemic  could
adversely affect our clinical trials and operations in other ways as well. For example, challenges may arise as a result of
patients,  members  of  the  clinical  team,  or  our  employees  becoming  infected  with  COVID-19  or  otherwise  unable  or
unwilling to participate in trials or come to work, as applicable, as a result of COVID-19, interruptions to the supply chain
or manufacturing, site closures, or difficulties in meeting protocol-specified procedures, including difficulties adhering to
protocol-mandated visits and testing. The COVID-19 pandemic may also increase the likelihood and severity of other risks
discussed  in  the  “Risk  Factors”  section  of  this  Annual  Report,  including  but  not  limited  to  risks  related  to  the  conduct,
progress  and  outcomes  of  clinical  trials,  risks  related  to  reliance  on  third  parties,  risks  related  to  our  operations  and
dependence on key personnel, and risks related to our need to obtain additional capital.

The  COVID-19  pandemic  and  its  impacts  continue  to  evolve,  including  the  emergence  of  variant  strains  of  the
COVID-19  virus.  Although  vaccines  are  now  available  are  being  distributed  globally,  we  cannot  predict  the  full  scope,
duration and severity of disruptions resulting from COVID-19 or their impacts on us. Business disruptions for us or the
third  parties  with  whom  we  engage,  including  the  collaborators,  contract  organizations,  third-party  manufacturers,
suppliers,  clinical  trial  sites,  regulators  and  other  third  parties  with  whom  we  conduct  business  could  materially  and
negatively impact our ability to conduct our business in the manner and on the timelines presently planned. The extent to
which the COVID-19 pandemic may impact our business and financial performance will depend on future developments,
which are highly uncertain and cannot be predicted with confidence, including the scope and duration of the pandemic and
the  extent  and  effectiveness  of  government  restrictions,  relief  measures  and  other  actions  implemented  to  address  the
impact of the pandemic, and resulting economic impacts.

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,  our  first  clinical  trial  for  our  second  product  candidate,  NC410,  in  June  2020,  and  our  third  product
candidate, NC762, in July 2021. 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,
NC762  and  any  future  product  candidates  we  develop,  which  may  never  occur.  Our  current  product  candidates  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:

● timely and successful completion of preclinical studies and our clinical trials;

● sufficiency  of  our  financial  and  other  resources  to  complete  the  necessary  preclinical  studies  and  clinical

trials;

● acceptance of INDs for any future product candidates;

● successful enrollment in and completion of clinical trials;

● successful  data  from  our  clinical  program  that  supports  an  acceptable  risk-benefit  profile  of  our  product

candidates in the intended patient populations;

● our ability to consistently manufacture our product candidates on a timely basis or to establish agreements

with third-party manufacturers, if needed;

● whether  we  are  required  by  the  FDA  or  comparable  foreign  regulatory  authorities  to  conduct  additional
clinical  trials  or  other  studies  beyond  those  planned  or  anticipated  to  support  approval  of  our  product
candidates;

● acceptance of our proposed indications and the primary endpoint assessments evaluated in the clinical trials

of our product candidates by the FDA and comparable foreign regulatory authorities;

● receipt and maintenance of timely marketing approvals from applicable regulatory authorities;

● successfully launching commercial sales of our product candidates, if approved;

● the  prevalence,  duration  and  severity  of  potential  side  effects  or  other  safety  issues  experienced  with  our

product candidates, if approved;

38

Table of Contents

● entry into collaborations to further the development of our product candidates;

● obtaining  and  maintaining  patent  and  trade  secret  protection  or  regulatory  exclusivity  for  our  product

candidates;

● acceptance  of  the  benefits  and  uses  of  our  product  candidates,  if  approved,  by  patients,  the  medical

community and third-party payors;

● maintaining  a  continued  acceptable  safety,  tolerability  and  efficacy  profile  of  the  product  candidates

following approval;

● our  compliance  with  any  post-approval  requirements  imposed  on  our  products,  such  as  post-marketing
studies, a REMS or additional requirements that might limit the promotion, advertising, distribution or sales
of our products or make the products cost-prohibitive;

● competing effectively with other therapies;

● obtaining and maintaining healthcare coverage and adequate reimbursement from third-party payors;

● our  ability  to  identify  targets  and  immunomedicines,  whether  through  our  FIND-IO  platform,  through  our

relationship with Yale or otherwise; and

● enforcing and defending intellectual property rights and claims.

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, NC762, NC525 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 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:

● the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our

clinical trials;

● we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities

that a product candidate is safe, pure and potent for its proposed indication;

39

Table of Contents

● the  results  of  clinical  trials  may  not  meet  the  level  of  statistical  significance  required  by  the  FDA  or

comparable foreign regulatory authorities for approval;

● we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety

risks;

● the  FDA  or  comparable  foreign  regulatory  authorities  may  disagree  with  our  interpretation  of  data  from

clinical trials or preclinical studies;

● the  data  collected  from  clinical  trials  of  our  product  candidates  may  not  be  sufficient  to  support  the
submission of a BLA to the FDA or regulatory submissions to comparable regulatory authorities to obtain
regulatory approval in such jurisdiction; and

● the  FDA  or  comparable  foreign  regulatory  authorities  may  find  deficiencies  with  or  fail  to  approve  our
manufacturing processes or facility or the manufacturing processes or facilities of third-party manufacturers
with which we contract for clinical and commercial supplies.

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  current  or  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,  development  of  an  in  vitro  companion  diagnostic,  or  other  post-marketing
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.

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  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 or 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  our  planned  clinical  trials  and
development  efforts.  Additionally,  we  cannot  be  certain  the  ongoing  and  planned  preclinical  studies  or  clinical  trials  for
NC318,  NC410,  NC762,  NC525  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. For example, we have modified the Phase 2
portion  of  our  ongoing  Phase  1/2  clinical  trial  of  NC318  for  S15  selection,  and  clinical  sites  can  select  for  S15-positive
patients  through  screening  biopsies  in  a  Clinical  Laboratory  Improvement  Amendments  (“CLIA”)-certified  laboratory,
which we anticipate will allow us to assess response rates in patients selected for S15. 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:

● results from preclinical studies or clinical trials may not be predictive of results from later clinical trials of

any product candidate;

40

Table of Contents

● the FDA or other regulatory authorities, IRBs or independent ethics committees may not authorize us or our

investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;

● the  FDA  or  other  regulatory  authorities  may  require  us  to  submit  additional  data  such  as  long-term

toxicology studies, or impose other requirements on us, before permitting us to initiate a clinical trial;

● we may experience delays in reaching, or fail to reach, agreement on acceptable terms with prospective trial
sites  and  prospective  contract  research  organizations,  or  “CROs”,  as  the  terms  of  these  agreements  can  be
subject to extensive negotiation and vary significantly among different CROs and trial sites;

● clinical trials of any product candidate may fail to show safety, purity or potency, or may produce negative or
inconclusive  results,  which  may  cause  us  to  decide,  or  regulators  to  require  us,  to  conduct  additional
nonclinical  studies  or  clinical  trials  or  which  may  cause  us  to  decide  to  abandon  product  candidate
development programs;

● the number of patients required for clinical trials may be larger than we anticipate or we may have difficulty
in recruiting and enrolling patients to participate in clinical trials, including as a result of the size and nature
of  the  patient  population,  the  proximity  of  patients  to  clinical  trial  sites,  eligibility  criteria  for  the  clinical
trial, the nature of the clinical trial protocol, the availability of approved effective treatments for the relevant
disease, competition from other clinical trial programs for similar indications and clinical trial subjects and
the impact of public health emergencies, such as the COVID-19 pandemic;

● it may be difficult to enroll a sufficient number of patients, enrollment in these clinical trials may be slower
than we anticipate, or participants may drop out of these clinical trials or may fail to return for post-treatment
follow-up at a higher rate than we anticipate;

● our  CROs  and  other  third-party  contractors  may  fail  to  comply  with  regulatory  requirements  or  meet  their
contractual obligations to us in a timely manner, or at all, or may deviate from the clinical trial protocol or
drop out of the trial, which may require that we add new clinical trial sites or investigators;

● we may elect to, or regulators, IRBs or ethics committees may require that we or our investigators, suspend
or  terminate  clinical  research  or  trials  for  various  reasons,  including  noncompliance  with  regulatory
requirements or a finding that participants are being exposed to unacceptable health risks;

● any  of  our  product  candidates  could  cause  undesirable  side  effects  that  could  result  in  significant  negative

consequences, including the inability to enter clinical development or receive regulatory approval;

● the cost of preclinical or nonclinical testing and studies and clinical trials of any product candidates may be

greater than we anticipate;

● we may face hurdles in addressing subject safety concerns that arise during the course of a trial, causing us or
our investigators, regulators, IRBs or ethics committees to suspend or terminate trials, or reports may arise
from nonclinical or clinical testing of other cancer therapies that raise safety or efficacy concerns about our
product candidates;

● the supply, quality or timeliness of delivery of materials for product candidates we develop or other materials

necessary to conduct clinical trials may be insufficient or inadequate; and

● we, or third parties on whom we are dependent, may suffer business interruptions resulting from geo-political
actions, including war and terrorism, or natural disasters and public health emergencies, such as the COVID-
19 pandemic.

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 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

41

Table of Contents

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.  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. In addition, factors outside our control, such
as government shutdowns, natural disasters and public health emergencies such as the COVID-19 pandemic, could disrupt
business at the FDA or other regulatory authorities, which could result in delays of reviews, approvals and communications
with regulatory authorities related to our clinical trials and product candidates.

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, NC410, and NC762, all of our product candidates are still in the preclinical 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 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:

42

Table of Contents

● an  inability  to  generate  sufficient  preclinical  or  other  in  vivo  or  in  vitro  data  to  support  the  initiation  of

clinical studies;

● delays in reaching a consensus with regulatory agencies on study design; and

● the FDA not permitting the reliance on preclinical or other data from published scientific literature.

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.  For  example,
notwithstanding the durable responses initially observed in our ongoing Phase 1/2 clinical trial of NC318 in NSCLC, we
announced in July 2020 that based on additional clinical response data we would not be advancing the NSCLC cohort into
the stage 2 portion of the Simon 2-stage trial. 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.

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 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.

Because the numbers of subjects in our Phase 1/2 clinical trials of NC318, NC410 and NC762 are small, the results
from each of these trials, 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  trials  of  NC318,  NC410  and  NC762,  can  be
disproportionately influenced by the impact the treatment had on a few individuals, which limits the ability to generalize

43

Table of Contents

the  results  across  a  broader  community,  thus  making  the  study  results  less  reliable  than  studies  with  a  larger  number  of
subjects and making it difficult to predict final results from preliminary results. As a result, there may be less certainty that
NC318, NC410, and NC762 would achieve a statistically significant effect in any future clinical trials. If we conduct any
future clinical trials of NC318, NC410, or NC762, we may not achieve a statistically significant result or the same level of
statistical  significance  seen,  if  any,  in  our  Phase  1/2  clinical  trials.  Similarly,  if  we  conduct  a  clinical  trial  of  any  other
product  candidate  we  develop  with  a  small  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.

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.

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.

Treatment-related adverse events experienced by more than 5% of patients in the Phase 1 portion of the Phase 1/2
clinical  trial  of  NC318  as  of  December  17,  2020  were  diarrhea,  infusion  reactions,  fatigue,  headaches,  pruritis,  elevated
amylase and elevated lipase. Most treatment-related adverse events in the Phase 1/2 clinical trial were easily manageable,
asymptomatic or mild or moderate, with the exception of one case of grade 3 episcleritis/uveitis that resolved after steroid
therapy and two cases of grade 3 pneumonitis. In the Phase 2 portion of the trial, the only observed severe or higher-grade
TRAE  as  of  that  date  was  a  grade  3-4  infusion  reaction  in  one  patient.  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 such as NC318. Immune-related adverse events reported in the Phase 1 portion of the Phase
1/2  clinical  trial  of  NC318  included  diarrhea,  elevated  amylase  and  lipase,  pruritis,  episcleritis/uveitis,  pneumonitis  and
vitiligo.

Possible  adverse  side  effects  that  could  occur  with  treatment  with  immunomedicines  include  an  immunologic
reaction early after administration that, 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

44

Table of Contents

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, NC762, NC525 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 are studying NC318 in combination with other therapies and may develop NC410, NC762, NC525
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:

● regulatory authorities may withdraw their approval of the product;

● we may be required to recall a product or change the way such product is administered to patients;

● additional  restrictions  may  be  imposed  on  the  marketing  of  the  particular  product  or  the  manufacturing

processes for the product or any component thereof;

● regulatory  authorities  may  require  the  addition  of  labeling  statements,  such  as  a  “black  box”  warning  or  a

contraindication;

● we  may  be  required  to  implement  a  REMS  or  create  a  Medication  Guide  outlining  the  risks  of  such  side

effects for distribution to patients;

● we could be sued and held liable for harm caused to patients;

● the product may become less competitive; and

● our reputation may suffer.

45

Table of Contents

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.

If there are continued 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. For
example, we experienced a slowdown of enrollment in our ongoing clinical trials as a result of the COVID-19 pandemic.
The enrollment of patients depends on many factors, including:

● the patient eligibility criteria defined in the protocol;

● the nature and size of the patient population required for analysis of the trial’s primary endpoints and the process

for identifying patients;

● the number and location of participating clinical sites or patients;

● the design of the trial;

● our ability to recruit clinical trial investigators with the appropriate competencies and experience;

● clinicians’  and  patients’  perceptions  as  to  the  potential  advantages  and  risks  of  the  product  candidate  being
studied  in  relation  to  other  available  therapies,  including  any  new  products  that  may  be  approved  for  the
indications we are investigating;

● the  availability  of  competing  commercially  available  therapies  and  other  competing  drug  candidates’  clinical

trials;

● our ability to obtain and maintain patient informed consents for participation in our clinical trials;

● the risk that patients enrolled in clinical trials will drop out of the trials before completion or, because they may

be late-stage cancer patients, will not survive the full terms of the clinical trials; and

● factors outside of our control, including as a result of business interruptions resulting from natural disasters and

public health emergencies, such as the COVID-19 pandemic.

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. Because 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 from difficulties in patient enrollment in a clinical trial may result in increased costs or affect the timing,
outcome  or  completion  of  the  trial,  which  could  delay  or  prevent  our  receipt  of  regulatory  approval  of  the  applicable
product candidate or to abandon the trial altogether.

46

Table of Contents

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  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:

● deficiencies in the conduct of the clinical trials, including failure to conduct the clinical trial in accordance

with regulatory requirements or study protocols;

● deficiencies in the clinical trial operations or trial sites;

● unforeseen adverse side effects or the emergence of undue risks to study subjects;

● deficiencies in the trial design necessary to demonstrate efficacy;

● the product candidate may not appear to offer benefits over current therapies; or

● the quality or stability of the product candidate may fall below acceptable standards.

We have chosen to prioritize development of NC318, NC410, NC762 and NC525. 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, NC410,
NC762 and NC525 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,  the  LAIR  pathway  or  B7-H4.  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 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 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 are being and 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.

47

Table of Contents

We  have  limited  experience  in  the  development  of  diagnostics  and,  as  such,  we  may  rely  in  part  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.

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.  Complementary
diagnostics may be subject to regulation by CMS or the FDA and similar comparable foreign regulatory authorities and
may  require  separate  regulatory  approval  or  clearance  prior  to  commercialization.  Gaining  regulatory  approval  could  be
time consuming and costly and could delay regulatory approval of the related product candidate.

We  and  our  collaborators  may  encounter  difficulties  in  developing  such  tests,  including  issues  relating  to  the
selectivity  or  specificity  of  the  diagnostic,  analytical  validation,  reproducibility  or  clinical  validation.  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:

● development  of  our  current  or  future  product  candidates  may  be  adversely  affected  if  we  are  unable  to

appropriately select patients for enrollment in our clinical trials; and

● we may not realize the commercial potential of our current or future product candidates if, among other reasons,
we are unable to appropriately identify, or it takes us longer to identify, patients who are likely to benefit from
therapy with our products, if approved.

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  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.

48

Table of Contents

The FDA or comparable foreign regulatory authorities can delay, limit or deny approval of our product candidates

for many reasons, including:

● our inability to demonstrate to the satisfaction of the FDA or a comparable foreign regulatory authority that

our product candidates are safe and effective for the requested indication;

● the  FDA  or  a  comparable  foreign  regulatory  authority’s  disagreement  with  our  trial  protocol  or  the

interpretation of data from preclinical studies or clinical trials;

● our inability to demonstrate that the clinical and other benefits of our product candidates outweigh any safety

or other perceived risks;

● the  FDA  or  a  comparable  foreign  regulatory  authority’s  requirement  for  additional  preclinical  studies  or

clinical trials;

● the  FDA  or  a  comparable  foreign  regulatory  authority’s  non-approval  of  the  formulation,  labeling,  or

specifications of our product candidates;

● the FDA or a comparable regulatory authority’s failure to approve our manufacturing processes and facilities

or the manufacturing processes and facilities of third-party manufacturers upon which we rely; or

● potential  for  approval  policies  or  regulations  of  the  FDA  or  a  comparable  foreign  regulatory  authority  to

significantly change in a manner rendering our clinical data insufficient for approval.

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 TME 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.

49

Table of Contents

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:

● efficacy  and  potential  advantages  compared  to  alternative  treatments,  including  those  that  are  not  yet

approved;

● the ability to offer our products, if approved, for sale at competitive prices;

● convenience and ease of administration compared to alternative treatments;

● the  willingness  of  the  target  patient  population  to  try  new  therapies  and  of  physicians  to  prescribe  these

therapies;

● the strength of marketing, sales and distribution support;

● the ability to obtain sufficient third-party coverage and adequate reimbursement, including with respect to the

use of the approved product as a combination therapy;

● the regulatory approval and adoption of a companion or complementary diagnostic, if needed or advisable;

and

● the prevalence and severity of any side effects.

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, NC762, NC525 and any other product candidates we develop
as second- or third-line therapies. If we 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 are studying NC318 in combination with other therapies and may develop NC410, NC762, NC525 and future
product candidates in combination with other therapies, which exposes us to additional regulatory risks.

We are studying NC318 in combination with pembrolizumab and may develop NC410, NC762, NC525 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

50

Table of Contents

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, NC762, NC525 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, NC762, NC525 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,  NC762,  NC525  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, 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:

● suspension of, or imposition of restrictions on, the marketing or manufacturing of the product, withdrawal of

the product from the market, or product recalls;

● Warning Letters or Untitled Letters, or holds on clinical trials;

● refusal  by  the  FDA  to  approve  pending  applications  or  supplements  to  approved  applications  we  file,  or

suspension or revocation of approved biologics licenses;

● product  seizure  or  detention,  monetary  penalties,  refusal  to  permit  the  import  or  export  of  the  product,  or

placement on Import Alert; and

● permanent injunctions and consent decrees including the imposition of civil or criminal penalties.

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 manufacturing 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.

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.

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 data and 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 information, including intellectual property,
proprietary business information, personal information, protected health 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. If we or our vendors
fail to comply with applicable data privacy laws, or if the legal mechanisms we or our vendors rely upon for the transfer of
personal  data  are  ever  deemed  inadequate,  or  if  we  or  our  vendors  experience  a  data  breach  resulting  in  exposure  of
personal  data  subject  to  the  applicable  laws,  we  could  be  subject  to  government  enforcement  actions  and  significant
penalties against us, criminal and civil liability for us and our officers and directors, private litigation or adverse publicity.

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. We
and our third party service providers regularly defend against, respond to and mitigate risks from data security incidents.
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,
ransomware 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  HIPAA  and  its  implementing
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. We may need to expend significant resources and make significant
capital investment to protect against security breaches or to mitigate the impact of any such breaches.

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

53

Table of Contents

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 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, the LAIR pathway or B7-H4. 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. Moreover,
eligibility for reimbursement does not imply that any drug will be reimbursed in all cases or at a rate that covers our costs,
including  research,  development,  manufacture,  sale  and  distribution.  Interim  reimbursement  levels  for  new  drugs,  if
applicable, may also not be sufficient to cover our costs and may not be made permanent. 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  can  change,  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,  a  primary  trend  in  the  healthcare  industry  in  the  United  States  and  elsewhere  is  cost  containment.
Government  authorities  and  third-party  payors  have  attempted  to  control  costs  by  limiting  coverage  and  the  amount  of
reimbursement  for  particular  medications.  Increasingly,  the  third-party  payors  who  reimburse  patients  or  healthcare
providers,  such  as  government  and  private  insurance  plans,  are  requiring  that  drug  companies  provide  them  with
predetermined discounts from list prices and are seeking to reduce the prices charged or the amounts reimbursed for

54

Table of Contents

medical  products.  We  cannot  be  sure  that  coverage  and  reimbursement  will  be  available  for  any  drug  that  we
commercialize  and,  if  coverage  and  reimbursement  are  available,  we  cannot  be  sure  as  to  the  level  of  reimbursement.
Reimbursement  may  impact  the  demand  for,  or  the  price  of,  any  product  candidate  for  which  we  obtain  marketing
approval.  If  reimbursement  is  not  available  or  is  available  only  to  limited  levels,  we  may  not  be  able  to  successfully
commercialize any product candidate for which we obtain marketing approval. 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,  the  ACA  substantially  changed  the  way
healthcare  is  financed  by  both  governmental  and  private  insurers,  and  significantly  impacted  the  U.S.  pharmaceutical
industry. The ACA, among other things, subjects biologics to potential competition by lower-cost biosimilars, addresses a
methodology by which rebates owed by manufacturers under the MDRP are calculated for drugs that are inhaled, infused,
instilled,  implanted  or  injected,  increases  the  minimum  Medicaid  rebates  owed  by  manufacturers  under  the  MDRP  and
extends  the  rebate  program  to  individuals  enrolled  in  Medicaid  managed  care  organizations,  and  establishes  annual  fees
and taxes on manufacturers of certain branded prescription drugs.

The  ACA  and  certain  of  its  provisions  have  been  subject  to  judicial  challenges  as  well  as  legislative  and
regulatory efforts to repeal or replace them or to alter their interpretation or implementation. 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 Act included a provision that repealed 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.” The Bipartisan Budget Act of 2018, among other things, amended the ACA to increase the point-
of-sale discounts that manufacturers must agree to offer under the Medicare Part D coverage discount program from 50%
to  70%  off  negotiated  prices  of  applicable  brand  drugs  to  eligible  beneficiaries  during  their  coverage  gap  period,  as  a
condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D. 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. The Further Consolidated Appropriations Act of 2020 fully repealed
the ACA’s “Cadillac Tax” on certain high cost employer-sponsored insurance plans and, effective in 2021, the annual fee
imposed  on  certain  health  insurance  providers  based  on  market  share.  On  January  28,  2021,  President  Biden  issued  an
Executive Order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of
obtaining  health  insurance  coverage  through  the  ACA  marketplace.  The  Executive  Order  also  instructed  certain
governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including
among others, policies that create barriers to obtaining access to health insurance coverage through the ACA marketplaces.
Most recently, on March 11, 2021, Congress enacted the American Rescue Plan Act of 2021, which included among its
provisions a sunset of the ACA’s cap on pharmaceutical manufacturers’ rebate liability under the Medicaid Drug Rebate
Program.  Under  the  ACA,  manufacturers’  rebate  liability  was  capped  at  100%  of  the  average  manufacturer  price  for  a
covered  outpatient  drug.  Effective  January  1,  2024,  manufacturers’  MDRP  rebate  liability  will  no  longer  be  capped,
potentially  resulting  in  a  manufacturer  paying  more  in  MDRP  rebates  than  it  receives  on  the  sale  of  certain  covered
outpatient drugs. The American Rescue Plan Act also temporarily increased premium tax credit assistance for individuals
eligible for subsidies under the ACA for 2021 and 2022 and removed the 400% federal poverty level limit that otherwise
applies for purposes of eligibility to receive premium tax credits. In the future, there may be additional challenges and/or
amendments  to  the  ACA.  It  remains  to  be  seen  precisely  what  any  new  legislation  will  provide,  when  or  if  it  will  be
enacted, and what impact it will have on the availability and cost of healthcare items and services, including drug products.

In  December  2018,  the  United  States  District  Court  for  the  Northern  District  of  Texas  ruled  that  the  individual

mandate is (i) unconstitutional as a result of the associated tax penalty being repealed by Congress as part of the Tax Act

55

Table of Contents

and (ii) not severable from the rest of the ACA, and that as a result the entire ACA is invalid. In December 2019, the U.S.
Court of Appeals for the Fifth Circuit affirmed the district court’s decision that the individual mandate is unconstitutional
but remanded the case to the district court to reconsider the severability question. The Supreme Court of the United States
granted certiorari on March 2, 2020 and heard oral argument on November 10, 2020. On June 17, 2021, the Supreme Court
dismissed the lawsuit without ruling on the merits of the states’ constitutionality arguments.

Other healthcare-related legislative and regulatory initiatives and reforms have been proposed and adopted in the
United States since the ACA was enacted. In August 2011, the Budget Control Act of 2011, among other things, created
measures for automatic spending reductions under certain circumstances. 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  reductions.  In  conjunction  with  the  operation  of
subsequently enacted law, this has resulted in aggregate reductions of Medicare payments to providers of, on average, 2%
per fiscal year into 2031, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022 and a
subsequent reduction to 1% from April 1, 2022 until June 30, 2022, unless Congress takes additional action. The American
Taxpayer Relief Act of 2012, which was signed into law in January 2013, among other things, further reduced Medicare
payments  to  several  types  of  providers  and  increased  the  statute  of  limitations  period  for  the  government  to  recover
overpayments to providers from three to five years.

Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives.
For example, beginning in 2018, CMS has maintained a reduced rate of payment under the Medicare outpatient prospective
payment system and ambulatory surgical center payment system for certain separately payable drugs or biologics acquired
under the 340B Drug Pricing Program, and a CMS indicated in a recent rule that it will continue to consider setting an even
lower payment rate based on collected hospital survey data. 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
and regulation designed 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;
and  reform  government  program  reimbursement  methodologies  for  drugs.  For  example,  on  November  20,  2020,  CMS
issued  an  interim  final  rule  that  implemented  a  mandatory  “Most  Favored  Nation”  demonstration  model  to  test
reimbursement of drugs or biologicals under Medicare Part B based on international reference prices, though the final rule
is currently subject to a nationwide preliminary injunction. Additionally, included in the Consolidated Appropriations Act,
2021 were several drug price reporting and transparency measures, such as a new requirement for certain Medicare plans to
develop  tools  to  display  Medicare  Part  D  prescription  drug  benefit  information  in  real  time  and  for  group  and  health
insurance issuers to report information on pharmacy benefit and drug costs to the Secretaries of the Departments of Health
and Human Services, Labor and the Treasury. Policymakers have also indicated that they will continue to seek legislative
and  administrative  measures  to  control  drug  costs.  For  example,  on  July  9,  2021,  President  Biden  issued  an  Executive
Order to promote competition in the U.S. economy that included several initiatives addressing prescription drugs. Among
other provisions, the Executive Order stated that the Biden administration will “support aggressive legislative reforms that
would lower prescription drugs, including by allowing Medicare to negotiate drug prices, by imposing inflation caps, and
through other related reforms.” In response to the Executive Order, on September 9, 2021, the Department of Health and
Human Services issued a Comprehensive Plan for Addressing High Drug Prices that identified potential legislative policies
and  administrative  tools  that  Congress  and  the  agency  can  pursue  in  order  to  make  drug  prices  more  affordable  and
equitable, improve and promote competition throughout the prescription drug industry, and foster scientific innovation. 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  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

56

Table of Contents

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,  in  May  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.

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,  those  described  in  “Business—Government  Regulation—Healthcare
Regulation.”

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.  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, 
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.

including  exclusion  from  government  funded  healthcare  programs.  In  addition,

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 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.

Manufacturing  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.

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.

Manufacturing 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, NC410, NC762 and NC525 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 sufficient 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,  NC410,  NC762  or  NC525.  Any  such
delays could materially adversely affect our business and financial condition.

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.
Currently,  our  product  candidates  are  manufactured  in  small  quantities  for  use  in  various  preclinical  studies  and  our
ongoing Phase 1/2 clinical trials of NC318, NC410 and NC762. We intend to expand our manufacturing capacity, including
to  provide  drug  supply  of  NC318  for  future  clinical  trials,  which  will  require  us  to  incur  significant  expenses.  If  one  or
more  of  our  product  candidates  progress  to  late-stage  development,  we  may  incur  additional  significant  expenses  in  the
further  expansion  or  construction  of  manufacturing  facilities  and  increases  in  personnel  in  order  to  manufacture  product
candidates  in  sufficient  quantities.  We  cannot  assure  you  that  we  will  be  able  to  successfully  manufacture  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.

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, NC762, NC525 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

59

Table of Contents

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 manufacturing 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 manufacturing
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.

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:

● product loss during the manufacturing process, including loss caused by contamination, equipment failure or
improper  installation  or  operation  of  equipment,  or  operator  error.  Even  minor  deviations  from  normal
manufacturing  processes  could  result  in  reduced  production  yields,  product  defects  and  other  supply
disruptions. If microbial, viral or other contaminations are discovered in our products or in the manufacturing
facilities  in  which  our  products  are  made,  such  manufacturing  facilities  may  need  to  be  closed  for  an
extended period of time to investigate and remedy the contamination;

● the  manufacturing  facilities  in  which  our  products  are  made  could  be  adversely  affected  by  equipment
failures, labor and raw material shortages, including due to restrictions on the movement of people or goods,
natural disasters, public health emergencies, power failures, other business disruptions and numerous other
factors; and

● any  adverse  developments  affecting  manufacturing  operations  for  our  products  may  result  in  shipment
delays, inventory shortages, lot failures, product withdrawals or recalls, or other interruptions in the supply of
our  products.  We  may  also  have  to  take  inventory  write-offs  and  incur  other  charges  and  expenses  for
products  that  fail  to  meet  specifications,  undertake  costly  remediation  efforts  or  seek  more  costly
manufacturing alternatives.

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. In addition, COVID-19 has disrupted global supply chains, including pharmaceutical and medical
supply chains. We cannot be certain that our suppliers will continue to provide us with the quantities of the raw materials
that we require or satisfy our anticipated specifications and quality requirements whether due to our size, COVID-19, or

60

Table of Contents

otherwise.  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.

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

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 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  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 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 were 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”, 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 included a number of significant changes
that affected 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.  Additional  changes  in  patent  law  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
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 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 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

64

Table of Contents

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
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

65

Table of Contents

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. For example, in 2020, a lawsuit was filed against our Chief Executive Officer alleging that he breached contractual
and  fiduciary  duties  to  a  third  party  by,  among  other  things,  improperly  utilizing  confidential  information  to  benefit  the
Company’s  business,  including  with  respect  to  our  discovery  efforts.  While  the  original  complaint  was  voluntarily
dismissed by the plaintiffs, there can be no assurance that the same or similar claims may not be brought against our Chief
Executive  Officer  or  us.  If  we  fail  in  defending  claims  of  misappropriation  and  similar  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:

● others may be able to make products that are similar to our product candidates but that are not covered by the

claims of the patents that we own or license or may own in the future;

● we,  or  any  partners  or  collaborators,  might  not  have  been  the  first  to  make  the  inventions  covered  by  the

issued patent or pending patent application that we license or may own in the future;

● we, or any partners or collaborators, might not have been the first to file patent applications covering certain

of our or their inventions;

● others  may  independently  develop  similar  or  alternative  technologies  or  duplicate  any  of  our  technologies

without infringing our owned or licensed intellectual property rights;

66

Table of Contents

● it is possible that our pending licensed patent applications or those that we may own in the future will not

lead to issued patents;

● issued  patents  that  we  hold  rights  to  may  be  held  invalid  or  unenforceable,  including  as  a  result  of  legal

challenges by our competitors;

● our competitors might conduct research and development activities in countries where we do not have patent
rights and then use the information learned from such activities to develop competitive products for sale in
our major commercial markets;

● we may not develop additional proprietary technologies that are patentable;

● the patents of others may have an adverse effect on our business; and

● we may choose not to file a patent for certain trade secrets or know-how, and a third party may subsequently

file a patent covering such intellectual property.

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, NC762, NC525 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, NC762, NC525 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  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,  including  as  a  result  of  natural  disasters  or  public  health  emergencies  such  as  the  COVID-19
pandemic, 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

67

Table of Contents

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 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  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:

● collaborators may have significant discretion in determining the efforts and resources that they will apply to

these collaborations;

● collaborators could independently develop, or develop with third parties, products that compete directly or

indirectly with our products or product candidates;

● collaborators may not properly enforce, maintain or defend our intellectual property rights or may use our
proprietary information in a way that gives rise to actual or threatened litigation or that could jeopardize or
invalidate  our  intellectual  property  or  proprietary  information,  exposing  us  to  potential  litigation  or  other
intellectual property proceedings;

● collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation

and potential liability;

● disputes  may  arise  between  a  collaborator  and  us  that  cause  the  delay  or  termination  of  the  research,
development  or  commercialization  of  the  product  candidate,  or  that  result  in  costly  litigation  or  arbitration
that diverts management attention and resources;

● a collaborator with marketing and distribution rights to one or more of our product candidates that achieve

regulatory approval may not commit sufficient resources to the marketing and distribution of such products;

● if a present or future collaborator were to be involved in a business combination, the continued pursuit and
emphasis  on  our  product  development  or  commercialization  program  under  such  collaboration  could  be
delayed, diminished or terminated; and

● collaboration agreements may restrict our right to independently pursue new product candidates.

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.

Effective  March  3,  2020,  Lilly  terminated  the  Lilly  Agreement,  which  was  focused  on  using  our  FIND-IO
platform  to  identify  novel  oncology  targets  for  additional  research  and  drug  discovery  by  ourselves  and  Lilly.  The
termination of the Lilly Agreement prevented us from receiving future research and development support payments, option
exercise fees, development and regulatory milestone payments, sales milestone payments or royalties under the agreement.
In the event a present or future collaborator terminates their agreement with us, we would be prevented from receiving the
benefits of any such agreement, which could have a materially adverse effect on our results of operations.

68

Table of Contents

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.

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,  and  we  do  not  have  “key  person”  insurance  on  them.  The  loss  of  the
services of one or more of our executive officers or of certain members of our SAB could impede the achievement of our
research, development and commercialization objectives.

Recruiting and retaining qualified employees, consultants and advisors for our business, including scientific and
technical  personnel,  is  critical  to  our  success.  We  have  observed  an  increasingly  competitive  labor  market.  Increased
employee turnover and changes in the availability of our workers could result in increased costs. 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

69

Table of Contents

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. Companies are also
developing treatments targeting the Siglec family of proteins, such as Celldex Therapeutics and Palleon Pharmaceuticals,
both of which are currently engaged in preclinical studies. 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,  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:

● identifying, recruiting, integrating, maintaining and motivating additional employees;

● managing  our  internal  development  efforts  effectively,  including  the  clinical  and  FDA  review  process  for
NC318, NC410, NC762 and any future product candidates we develop, while complying with our contractual
obligations to contractors and other third parties; and

● improving our operational, financial and management controls, reporting systems and procedures.

Our  future  financial  performance  and  our  ability  to  advance  development  of  and,  if  approved,  commercialize
NC318,  NC410,  NC762,  NC525  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, NC762, NC525 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, NC762, NC525 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,  NC762,
NC525 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:

● our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel;

● the inability of sales personnel to obtain access to physicians in order to educate physicians about our product

candidates, once approved;

● the  lack  of  complementary  products  to  be  offered  by  sales  personnel,  which  may  put  us  at  a  competitive

disadvantage relative to companies with more extensive product lines; and

71

Table of Contents

● unforeseen costs and expenses associated with creating an independent sales and marketing organization.

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:

● decreased demand for any product candidate we may develop;

● withdrawal of trial participants;

● termination of clinical trial sites or entire trial programs;

● injury to our reputation and significant negative media attention;

● initiation of investigations by regulators;

● significant time and costs to defend the related litigation;

● substantial monetary awards to trial subjects or patients;

● diversion of management and scientific resources from our business operations; and

● the inability to commercialize any product candidates that we may develop.

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.

72

Table of Contents

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 December 31, 2021, we had federal
and state net operating loss carryforwards of $160.9 million and $163.4 million, respectively. Certain 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, 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.

Natural disasters or other unexpected events may disrupt our operations, adversely affect our results of operations and
financial condition, and may not be covered by insurance.

The occurrence of one or more unexpected events, including fires, tornadoes, tsunamis, hurricanes, earthquakes,
floods,  and  other  forms  of  severe  hazards  in  the  United  States  or  in  other  countries  in  which  we  or  our  suppliers  or
manufacturers  operate  or  are  located  could  adversely  affect  our  operations  and  financial  performance.  These  types  of
unexpected events could result in physical damage to and complete or partial closure of one or more of the manufacturing
facilities operated by our contract manufacturers, or the temporary or long-term disruption in the supply of products, and/or
disruption  of  our  ability  to  deliver  products  to  customers.  Further,  the  long-term  effects  of  climate  change  on  general
economic conditions and the pharmaceutical manufacturing and distribution industry in particular are unclear, and changes
in the supply, demand or available sources of energy and the regulatory and other costs associated with energy production
and  delivery  may  affect  the  availability  or  cost  of  goods  and  services,  including  natural  resources,  necessary  to  run  our
businesses.  Existing  insurance  arrangements  may  not  provide  protection  for  the  costs  that  may  arise  from  such  events,
particularly if such events are catastrophic in nature or occur in combination. Any long-term disruption in our ability to
service our customers from one or more distribution centers or outsourcing facilities could have a material adverse effect
on our operations, our business, results of operations and stock price.

Failure to meet investor and stakeholder expectations regarding environmental, social and corporate governance, or
“ESG” matters may damage our reputation.

There  is  an  increasing  focus  from  certain  investors,  customers,  consumers,  employees  and  other  stakeholders
concerning ESG matters. Additionally, public interest and legislative pressure related to public companies’ ESG practices
continue to grow. If our ESG practices fail to meet investor, customer, consumer, employee or other stakeholders’ evolving
expectations  and  standards  for  responsible  corporate  citizenship  in  areas  including  environmental  stewardship,  Board  of
Directors  and  employee  diversity,  human  capital  management,  corporate  governance  and  transparency,  our  reputation,
brand, appeal to investors and employee retention may be negatively impacted, which could have a material adverse effect
on our business or financial condition.

Risks Related to Our Common Stock

The price of our common stock has been and may continue to be volatile and fluctuate substantially.

Our  stock  price  has  been  and  is  likely  to  remain  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 or prospects of particular companies. As a result of this volatility, you may not be able to sell your
common stock at or above a recently reported price, or at all. The market price for our common stock may be influenced by
many factors, including:

● the  commencement,  enrollment  or  results  of  our  ongoing  or  future  clinical  trials,  or  changes  in  the

development status of our product candidates;

● any  delay  in  our  regulatory  filings  for  our  product  candidates  and  any  adverse  development  or  perceived
adverse development with respect to the applicable regulatory authority’s review of such filings, including
without limitation the FDA’s issuance of a “refusal to file” letter or a request for additional information;

● adverse results or delays in clinical trials;

● our decision to initiate a clinical trial, not to initiate a clinical trial or to terminate an existing clinical trial;

● adverse regulatory decisions, including failure to receive regulatory approval of our product candidates;

● our failure to commercialize our product candidates;

● unanticipated serious safety concerns related to the use of our product candidates;

● the size and growth of our target markets;

● the success of competitive products or technologies;

● regulatory actions with respect to our product candidates or our competitors’ products or product candidates;

● announcements by us or our competitors of significant acquisitions, strategic collaborations, joint ventures,

collaborations or capital commitments;

● regulatory  or  legal  developments  in  the  United  States  and  other  countries  applicable  to  our  product

candidates, including but not limited to clinical trial requirements for approvals;

● our inability to obtain adequate product supply for any approved product or inability to do so at acceptable

prices;

● developments or disputes concerning patent applications, issued patents or other proprietary rights;

● the recruitment or departure of key personnel;

● the level of expenses related to our product candidates or clinical development programs;

● the results of our efforts to discover, develop, acquire or in-license product candidates;

● actual or anticipated changes in estimates as to financial results, development timelines or recommendations

by securities analysts or publications of research reports about us or our industry;

● variations in our annual or quarterly financial results or those of companies that are perceived by investors to

be similar to us;

74

Table of Contents

● our cash position;

● fluctuations in the valuation of companies perceived by investors to be comparable to us;

● share price and volume fluctuations attributable to inconsistent trading volume levels of our shares;

● announcement or expectation of additional financing efforts;

● sales of our common stock by us, our directors, officers or their affiliated funds or our other stockholders;

● changes in the structure of healthcare payment systems;

● significant lawsuits, including patent or stockholder litigation;

● market conditions in the pharmaceutical and biotechnology sectors;

● general economic, industry and market conditions; and

● other events or factors, many of which are beyond our control, or unrelated to our operating performance or

prospects.

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 inaccurate or unfavorable
research about our business, 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.  We  currently  receive  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.

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 significantly.

We have filed registration statements on Form S-8 shares of common stock that are either subject to options or
other equity awards issued or reserved for future issuance under our equity incentive plans. The number of shares available
for  issuance  under  the  2019  Omnibus  Plan  is  subject  to  an  automatic  annual  increase  on  January  1st  of  each  year,
continuing until the expiration of the 2019 Omnibus Plan, in an amount equal to four percent (4%) of the total number of
shares of Common Stock outstanding on December 31st of the preceding calendar year. The number of shares available for
issuance under the 2019 Employee Stock Purchase Plan, or “ESPP”, is subject to an automatic annual increase on January
1st of each year, continuing until the expiration of the ESPP, in an amount equal to the least of (i) one percent (1%) of the
total number of shares of Common Stock outstanding on December 31st of the preceding calendar year, (ii) 480,000 shares
of Common Stock (subject to the capitalization adjustment provisions included in the ESPP) and (iii) a number of shares of
Common Stock determined by the administrator of the ESPP. Shares registered under our registration statements on Form
S-8  will  be  available  for  sale  in  the  public  market  subject  to  vesting  arrangements  and  exercise  of  options  and  the
restrictions of Rule 144 in the case of our affiliates.

75

Table of Contents

In addition, the holders of certain shares of our common stock outstanding as of December 31, 2021 are entitled to
rights  with  respect  to  the  registration  of  their  shares  under  the  Securities  Act.  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 these securities, or the perception that they will be sold, could have a material
adverse effect on the market price of our common stock.

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:

● delaying, deferring or preventing a change of control of us;

● impeding a merger, consolidation, takeover or other business combination involving us; or

● discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us.

We are now and may in the future be subject to securities litigation, which can be expensive and could divert
management’s attention.

On September 21, 2020, a putative stockholder class action was filed in the U.S. District Court for the Southern
District of New York styled Ye Zhou v. NextCure, Inc., et. al., Case 1:20-cv-0772 (S.D.N.Y.). On February 26, 2021, the
Lead Plaintiff filed a consolidated amended complaint that asserts claims against us, certain of our officers and members of
our  board  of  directors,  and  the  underwriters  in  our  May  2019  initial  public  offering  and  November  2019  underwritten
secondary  public  offering.  The  complaint  alleges  that  the  defendants  violated  provisions  of  the  Exchange  Act  and  the
Securities Act of 1933, as amended, with respect to statements made regarding our lead product candidate, NC318, and the
FIND-IO platform.

On March 24, 2021, a purported shareholder derivative lawsuit was filed in the U.S. District Court for the District
of Maryland, Southern Division, styled Zach Liu v. Richman et. al., Case:21-cv-00754, alleging breaches of fiduciary duty
by  officers  and/or  directors,  unjust  enrichment,  abuse  of  control,  gross  mismanagement,  waste  of  corporate  assets  and
violations of the Exchange Act and the Securities Act of 1933. The Complaint seeks unspecified damages, attorneys’ fees
and  costs,  declaratory  relief,  corporate  governance  changes,  and  restitution.  For  more  information  regarding  these
proceedings, please refer to Note 10 to the Company’s Financial Statements.

On December 14, 2021, a purported misappropriation of certain trade secrets lawsuit was filed in Federal District
Court for the District of Delaware, styled Immunaccel, LLC v. NextCure, Inc., Case No. 1:21-cv-01755-UNA. The lawsuit
alleges that the Company misappropriated certain trade secrets belonging to Immunaccel, LLC, or “Immunaccel”, related
to a drug discovery and screening platform named IMMUNE 3D. The complaint alleges two causes of action, one under
the Delaware Uniform Trade Secrets Act and another under the Federal Defend Trade Secrets Act, and seeks unspecified
monetary damages, a permanent injunction and other miscellaneous relief.

We  intend  to  vigorously  defend  these  actions.  However,  whether  or  not  the  claims  are  successful,  litigation  is
often expensive and can divert management’s attention and resources from other business concerns, which could adversely
affect  our  business.  If  we  are  ultimately  required  to  pay  significant  defense  costs,  damages  or  settlement  amounts,  such
payments could adversely affect our operations.

We may be the target of similar litigation in the future. The market price of our common stock has experienced
and may continue to experience volatility, and in the past, companies that have experienced volatility in the market price of
their stock have been subject to securities litigation. Any future litigation could result in substantial costs and divert our
management’s attention from other business concerns, which could seriously harm our business. We maintain liability

76

Table of Contents

insurance; however, if any costs or expenses associated with the Ye Zhou action, Liu action, or any other litigation exceed
our insurance coverage, we may be forced to bear some or all costs and expenses directly, which could be substantial.

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.

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.

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 pursuant to Section 404 of the
Sarbanes Oxley Act. 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  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 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 we have incurred, and we expect, particularly after we are no longer an emerging growth
company, to continue to incur significant legal, accounting, investor relations and other expenses that we did not incur as a
private company. 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.

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.

Market Information and Holders of Record

Our common stock trades on the Nasdaq Global Select Market, or “Nasdaq”, under the symbol “NXTC.” As of
March 2, 2022 we had 27,724,303 holders of record of our common stock. The actual number of shareholders is greater
than this number of record holders and includes shareholders who are beneficial owners but whose shares are held in street
name by brokers and other nominees. This number of holders of record also does not include shareholders whose shares
may be held in trust by other entities.

Dividends

We  have  never  declared  or  paid  cash  dividends  on  our  capital  stock,  and  we  do  not  anticipate  paying  any  cash
dividends in the foreseeable future. We currently intend to retain all available funds and any future earnings to support our
operations and finance the growth and development of our business.

Use of Proceeds from Initial Public Offering

On May 13, 2019, we closed our IPO pursuant to which we issued and 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 offer and sale of the shares
was made pursuant to a registration statement on Form S-1 (File No. 333-230837) that the SEC declared effective on May
9, 2019. Morgan Stanley & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Piper Jaffray & Co. acted as
joint book-running managers of our IPO. The net offering proceeds to us were approximately $76.9 million after deducting
underwriting discounts and commissions of $6.0 million and offering expenses of approximately $3.4 million. During the
period from the closing of our IPO on May 13, 2019 through December 31, 2021, $0.5 million of the net proceeds from our
IPO have been used for payment to Yale University in connection with the closing of our IPO, and the remainder has been
invested in temporary investments pending other uses.

None of the offering expenses or net proceeds were paid directly or indirectly to any of our directors or officers
(or their associates) or persons owning 10% or more of any class of our equity securities or to any other affiliates. There
has been no material change in the planned use of proceeds from our IPO from those disclosed in the final prospectus that
forms a part of our Registration Statement on Form S-1 (Reg. No. 333-230837), as filed with the SEC pursuant to Rule
424(b)(4) under the Securities Act of 1933, as amended, on May 9, 2019.

Item 7. 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  financial  statements  and  the  related  notes  appearing  elsewhere  in  this  Annual  Report.  This  discussion  contains
forward-looking  statements  that  are  based  on  management’s  current  expectations,  estimates,  and  projections  about  our
business  and  operations,  and  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  sections  entitled  “Risk  Factors”  and  “Special  Note  Regarding  Forward-Looking
Statements”  and  elsewhere  in  this  Annual  Report.  The  following  discussion  and  analysis  is  expected  to  better  allow
investors to view the company from management’s perspective.

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 protein
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  were  presented  at  the  Society  for  Immunotherapy  of  Cancer  annual  meeting,  or  the  “SITC
Meeting”, in November 2019. Updated data were presented in December 2020 and November 2021.

We began enrolling patients in the Phase 2 portion of the Phase 1/2 clinical trial of NC318 in October 2019. In this
portion, we planned to enroll up to 100 patients with tumor types that have been shown to have elevated S15 expression,
including non-small cell lung cancer, or “NSCLC”, ovarian cancer, head and neck squamous cell carcinoma, or “HNSCC”,
and triple-negative breast cancer, or “TNBC”.

We  have  modified  the  Phase  2  portion  of  the  trial  for  S15  selection,  whereby  clinical  sites  can  select  for  S15-
positive  patients  through  screening  biopsies  in  a  Clinical  Laboratory  Improvement  Amendments  (“CLIA”)-certified
laboratory.  In  the  second  quarter  of  2021,  we  revised  the  dosing  regimen  to  800  mg  weekly  to  increase  overall  drug
exposure  to  NC318.  We  provided  a  data  update  from  our  ongoing  Phase  2  monotherapy  trial  of  NC318  at  the  SITC
Meeting in November 2021.  Based on combined Phase 1 and Phase 2 data from the NC318 study, NC318 continued to
show  early  evidence  of  possible  clinical  benefit  in  patients  with  HNSCC,  lung  and  breast  cancer  and  other
advanced/metastatic solid tumors, with dosing once every two weeks during dose escalation and a dose of 400 mg selected
for the Phase 2 studies. NC318 continued to be well-tolerated in the Phase 2 portion of the trial, with primarily mild or
moderate treatment-related adverse events, or “TRAE”. We expect to provide further data from the Phase 2 portion of this
trial in the fourth quarter of 2022.

In April 2021, Yale University commenced a Phase 2 investigator-initiated clinical trial of NC318 in combination

with pembrolizumab in patients with NSCLC. Initial data are anticipated in the second half of 2022.

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,  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 is designed to evaluate the safety and tolerability of NC410 and determine
its pharmacologically active and/or maximum tolerated dose. Interim data presented from the Phase 1 dose-escalation study
shows that NC410 appears to be safe and well-tolerated in patients with advanced tumors and show evidence of immune
modulation. We expect to provide further data from the Phase 1 portion of this trial in the second half of 2022.

Table of Contents

Our  third  product  candidate,  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  potentially  other  tumor  types.  The  Phase  1  dose-escalation  portion  of  this
open-label  trial  is  being  designed  to  evaluate  the  safety  and  tolerability  of  NC762  and  determine  its  pharmacologically
active  and/or  maximum  tolerated  dose.  We  expect  to  announce  initial  data  from  the  Phase  1  portion  of  this  trial  in  the
second half of 2022.

Our  fourth  product  candidate,  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,  or  the  “ASH  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, or
“CDX”,  animal  model  in  vivo  and  (iii)  restricts  AML  progression  in  patient-derived  xenografts,  or  “PDX”,  in  vivo.  An
IND submission is planned for the fourth quarter of 2022.

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. As a result,
with the exception of the three months ended March 31, 2020, for which we reported a profit due to recognition of deferred
revenue in connection with the termination of our former research and development collaboration agreement with Eli Lilly
and  Company,  or  “Lilly”,  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,  2021  and  2020  were  $69.4  million  and  $36.6  million,
respectively. As of December 31, 2021, we had an accumulated deficit of $187.0 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 public offerings of our common stock, with
private  placements  of  our  preferred  stock  and  with  upfront  fees  received  under  our  former  research  collaboration  and
development agreement with Lilly, or the “Lilly Agreement,” which was terminated in March 2020. From our inception
through December 31, 2021, 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, and we were
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. See Note 1 to our audited financial statements included elsewhere in this Annual
Report for more information.

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 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 December 31, 2021, we had cash, cash equivalents and marketable securities, excluding restricted cash, of

$219.6 million. We believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our

81

Table of Contents

planned  operations  into  the  first  quarter  of  2024.  We  have  based  this  estimate  on  assumptions  that  may  prove  to  be
incorrect, and we could exhaust 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 Phase 1/2 clinical trial and
planned Phase 2 clinical trial of NC318, our ongoing Phase 1/2 clinical trial of NC410, our ongoing Phase 1/2 clinical trial
for NC762, 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.

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

For  the  fiscal  year  ended  December  31,  2020,  we  recognized  deferred  revenue  related  to  the  terminated  Lilly

Agreement of $22.4 million. Through December 31, 2021, we have not generated any revenue from product sales.

For  additional  information  about  our  revenue  recognition  policy,  see  Note  2  to  our  audited  financial  statements

included elsewhere in this Annual Report.

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
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

82

Table of Contents

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,
and as we utilize our current good manufacturing practice, or “cGMP”, manufacturing capacity, including to provide drug
supply of NC318, NC410, NC762 and NC525 for future clinical trials, and as we expand our pipeline through research and
development activities, including through our FIND-IO platform and discovery programs.

We  cannot  determine  with  certainty  the  duration  and  costs  of  future  clinical  trials  of  NC318,  NC410,  NC762,
NC525 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, NC762, NC525 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 NC318, NC410 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 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  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

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,
including  as  a  result  of  expected  staff  expansion,  additional  occupancy  costs,  higher  legal  and  accounting  fees,  investor
relations costs, higher insurance premiums and other compliance costs.

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  year  ended  December  31,  2021  increased  by  $3.6  million  to  $50.2
million  compared  to  $46.6  million  for  the  year  ending  December  31,  2020.  The  increase  was  driven  primarily  by  $2.3
million  in  clinical-related  and  $2.1  million  in  personnel-related  expenses,  offset  by  a  $1.6  million  decrease  in  contract
manufacturing expenses. Another $0.8 million of increased expense was due to other items, primarily depreciation.

General and Administrative Expenses

General  and  administrative  expenses  for  the  year  ended  December  31,  2021  increased  by  $3.5  million  to  $20.5
million as compared to $17.0 million for the year ending December 31, 2020. The increase was driven primarily by $2.7
million  in  personnel-related  costs.  Another  $0.8  million  of  increased  expense  was  due  to  other  items,  including
professional services and insurance.

Other Income, Net

Other  income,  net  for  the  year  ended  December  31,  2021  decreased  by  $3.2  million  to  $1.4  million  from  $4.6

million for the year ended December 31, 2020 due to lower investment balances and a reduction in interest rates.

Liquidity and Capital Resources

We have financed our operations primarily with proceeds from public offerings of our common stock, with private
placements of our preferred stock and with 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 aggregate
gross  proceeds  of  $86.3  million.  The  net  offering  proceeds  to  us  were  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 the public offering price of $36.75 per share. The total gross proceeds to us were $172.2 million and the total 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 equivalents are held in money market funds.

On May 6, 2021, the Company entered into a sales agreement, or the “Sales Agreement”, with SVB Leerink LLC,
or 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 December 31, 2021, we had cash, cash equivalents and marketable securities, excluding restricted cash, of
$219.6 million. We believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our
planned operations into the first quarter of 2024.

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. In August 2021, we fully
paid the remaining principal on the Term Loan, and there are no outstanding payments due from us.

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, including as a result of
the impact of the COVID-19 pandemic. 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. Our need to raise additional capital will depend on many factors, including:

● the  scope,  progress,  results  and  costs  of  researching  and  developing  NC318,  NC410,  NC762,  NC525  and  our
other programs, including targets identified through our FIND-IO platform, and of conducting preclinical studies
and clinical trials;

● the timing of, and the costs involved in, obtaining marketing approvals for NC318, NC410, NC762, NC525 and

any future product candidates we develop, if clinical trials are successful;

85

Table of Contents

● the  costs  of  manufacturing  NC318,  NC410,  NC762,  NC525  and  any  future  product  candidates  we  develop  for

preclinical studies and clinical trials in preparation for marketing approval and commercialization;

● the costs of commercialization activities, including marketing, sales and distribution costs, for NC318, NC410,
NC762, NC525 and any future product candidates we develop, whether alone or with a collaborator, if any such
product candidates are approved for sale, including marketing, sales and distribution costs;

● our ability to establish and maintain additional collaborations, licenses or other arrangements on favorable terms,

if at all;

● the  costs  involved  in  preparing,  filing,  prosecuting,  maintaining,  expanding,  defending  and  enforcing  patent

claims, including litigation costs and the outcome of any such litigation;

● our current collaboration and license agreements remaining in effect and our achievement of milestones and the
timing and amount of milestone payments we are required to make, or that we may be eligible to receive, under
those agreements;

● the timing, receipt and amount of sales of, or royalties on, our future products, if any; and

● the emergence of competing therapies and other adverse developments in the oncology market.

Adequate  additional  financing  may  not  be  available  to  us  on  acceptable  terms,  or  at  all.  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  raise  additional  funds  through  government  or  private  grants,  collaborations,
strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish
valuable rights to our future revenue streams, product candidates or research programs or to grant licenses on terms that
may not be favorable to us. 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.

Cash Provided by Investing Activities

Cash  provided  by  investing  activities  for  the  year  ended  December  31,  2021  was  $36.6  million,  which  was
primarily  due  to  net  proceeds  from  marketable  securities  of  $39.0  million,  partially  offset  by  purchases  of  property  and
equipment of $2.4 million. Cash provided by investing activities for the year ended December 31, 2020 was $43.5 million,
which  was  primarily  due  to  net  proceeds  from  marketable  securities  of  $50.6  million,  partially  offset  by  purchases  of
property and equipment of $7.1 million.

Cash Used in Financing Activities

Cash  used  in  financing  activities  was  $3.3  million  for  the  year  ended  December  31,  2021,  which  consisted
primarily of payments related to the closure of the Term Loan. Cash used in financing activities was $1.4 million for the
year ended December 31, 2020, which consisted primarily of payments related to the Term Loan.

Contractual Obligations and Commitments

Operating Leases

In  February  2016,  we  entered  into  a  non-cancelable  facilities  operating  sublease,  or  the  2016  Sublease,  for  our
current headquarters that expires in August 2025. The base rent under the 2016 Sublease is $32,254 per month, plus our
prorated share of the sublandlord’s operating expense and is subject to annual rent increases of 3%.

In January 2019, we entered into a new lease to be used for office and laboratory space, or the 2019 Lease, that
expires in March 2030. Upon expiration of the 2016 Sublease, the 2019 Lease will also cover the space we are currently
subleasing  under  the  2016  Sublease.  The  base  rent  under  the  2019  Lease  is  $37,824  per  month,  subject  to  annual  rent
increases of 3%.

Term Loan

In April 2016, we entered into a $1.0 million term loan, or the Term Loan. In January 2019, we amended the Term
Loan  to  increase  our  borrowing  capacity  to  $5.0  million,  secured  by  our  certificates  of  deposit,  money  market  account,
investment property and deposit or investment accounts. In August 2021, we fully paid the remaining principal balance of
$2.4  million  of  the  Term  Loan.  Interest  expense  under  the  Term  Loan  was  approximately  $77,000  and  $183,000  for  the
years  ended  December  31,  2021  and  2020,  respectively.  The  outstanding  balance  on  the  Term  Loan  totaled  $0  and  $3.5
million as of December 31, 2021 and 2020, respectively.

We  also  have  potential  contingent  payment  obligations  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
agreement with Yale. 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.

Critical Accounting Policies, Significant Judgments and Use of Estimates

Our 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 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.

87

Table of Contents

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, as
these policies relate to the more significant areas involving management’s judgments and estimates.

Research and Development Expenses, Including Clinical Trial Accruals

Research costs consist of employee-related costs, contractor expenses, laboratory supplies and facility costs, for
research  and  development  of  product  candidates  are  expensed  as  incurred.  Development  costs,  including  clinical  trial-
related  expenses,  incurred  by  third  parties,  such  as  CROs,  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.  When  evaluating  the
adequacy  of  the  accrued  liabilities,  we  analyze  progress  of  the  studies,  including  the  phase  or  completion  of  events,
invoices  received  and  contracted  costs.  For  further  discussion  of  research  and  development  expenses,  including  clinical
trial accruals, see Note 2 to our audited financial statements included elsewhere in this Annual Report.

Revenue Recognition

We  account  for  revenue  in  accordance  with  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  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,  we  perform  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)  we
satisfy each performance obligation. We only apply the five-step model to contracts when it is probable that we will collect
consideration  to  which  we  are  entitled  in  exchange  for  the  goods  or  services  we  transfer  to  the  customer.  For  further
discussion of revenue recognition, see Note 2 to our audited financial statements included elsewhere in this Annual Report.

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  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 and recognize
forfeitures  as  they  occur.  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.

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 by 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.

88

Table of Contents

Since the closing of our IPO, we have 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.

For  further  discussion  of  our  accounting  for  stock-based  compensation,  see  Note  2  to  our  audited  financial

statements included elsewhere in this 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 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.

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, 2021
and 2020, the related statements of operations and comprehensive loss, 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, 2021 and 2020,
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 2018.

NEXTCURE, INC.
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.

Public Offerings of Common Stock

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 $3.4 million.

In preparation for the IPO, on May 3, 2019, the Company effected a 1-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,  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.  Additionally,  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.

On November 19, 2019, the Company completed an underwritten public offering, in which the Company 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  total  net  proceeds  to  the  Company  of  $160.9  million  after  deducting  underwriting  discounts  and
commissions of $10.3 million and offering expenses of $1.0 million.

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  December  2021,  the  Company  has  funded  its  operations
primarily with proceeds from public offerings of its common stock, private placements of its preferred stock and upfront
fees received under the Company’s former agreement with Eli Lilly and Company (Note 7). The Company expects to incur
additional operating losses and negative operating cash flows for the foreseeable future.

As of the issuance date of the financial statements for the year ended December 31, 2021, the Company expects
that its cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements into
the first quarter of 2024. The future viability of the Company beyond that date may depend on its ability to raise additional
capital to finance its operations.

96

Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

The  Company  plans  to  seek  additional  funding  through  public  or  private  equity  offerings,  debt  financings,
marketing and distribution arrangements, other collaborations, strategic alliances, licensing arrangements or other methods.
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.

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; its 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  the  Company’s  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.

COVID-19

The impact of the COVID-19 pandemic (including the impact of emerging variant strains of the COVID-19 virus)
on the Company’s 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  “lockdown,”  “social  distancing”  and  “shelter  in  place”  directives  and
other 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, has placed significant strain on
the Company’s clinical trial sites, has raised concerns around monitoring patient safety, and has caused enrollment to slow
in the Company’s clinical trials. Any rise of COVID-19 infection rates, especially in the United States, could continue to
negatively affect enrollment going forward. The Company continues to closely monitor the COVID-19 situation and any
potential impact to the Company’s planned activities.

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  chief  operating  decision  maker  views  the  operations  and  manage  the  business  in  one
operating segment that operates exclusively in the United States.

2. Summary of Significant Accounting Policies

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

97

Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

Standards  Codification  (‘‘ASC’’)  and  Accounting  Standards  Update  (‘‘ASU’’)  of  the  Financial  Accounting  Standards
Board (‘‘FASB’’).

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.  These  estimates  and
assumptions  affect  the  reported  amounts  of  assets  and  liabilities,  the  disclosure  of  contingent  assets  and  liabilities  at  the
date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  for  the  period  presented.  Although
actual results could differ from those estimates, management does not believe that such differences would be material.

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. Cash equivalents are stated at amortized cost, plus accrued interest, which approximates fair value.

Restricted Cash

In August 2021, the Company fully paid the remaining principal balance of $2.4 million of its $5.0 million term
loan (the “Term Loan”). As a result of this payment, the Company has no restricted cash held in support of the Term Loan.
The  required  Term  Loan  reserve  totaled  $0  and  $3.5  million  as  of  December  31,  2021  and  2020,  respectively.  These
amounts are presented in part as restricted cash and in part as other assets on the accompanying balance sheets.

The following table reconciles cash and cash equivalents and restricted cash per the balance sheet to the statement

of cash flows:

Marketable securities primarily consist of government debt securities, corporate bonds and agency bonds. These
marketable securities are classified as available-for-sale, and as such, are carried at fair value as determined by prices for
identical or similar securities at the balance sheet date. Marketable securities consist of Level 2 financial instruments in the
fair-value  hierarchy.  The  Company’s  policy  is  to  classify  all  investments  with  contractual  maturities  within  one  year  as
current.  At  each  reporting  date,  the  Company  evaluates  the  classification  of  its  investments  with  maturities  beyond  one
year  based  on  the  nature  of  the  investment  securities  and  whether  the  investments  are  considered  available  for  use  in
current  operations.  Investment  income  is  recognized  when  earned  and  reported  net  of  investment  expenses.  Unrealized
holding gains and losses are reported within accumulated other comprehensive income (loss) as a separate component of
stockholders’  equity.  The  amortized  cost  of  debt  securities  is  adjusted  for  amortization  of  premiums  and  accretion  of
discounts  to  maturity.  Such  amortization  and  interest  on  securities  are  included  in  other  income,  net,  on  the  Company’s
statements of operations.

At  each  balance  sheet  date,  the  Company  assesses  available-for-sale  securities  in  an  unrealized  loss  position  to
determine whether the unrealized loss is other-than-temporary. If a decline in the fair value of a marketable security below
the  Company’s  cost  basis  is  determined  to  be  other-than-temporary,  such  marketable  security  is  written  down  to  its
estimated fair value as a new cost basis and the amount of the write-down is included in earnings as an impairment charge.
The Company considers factors including the significance of the decline in value compared to the cost basis, underlying
factors contributing to a decline in the prices of securities in a single asset class, the length of time the market value of the
security has been less than its cost basis, the security's relative performance versus its peers, sector or asset class, expected
market volatility and the market and economy in general. The Company also evaluates whether it is more likely than not

98

     
     
 
 
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

that it will be required to sell a security prior to recovery of its fair value. The cost of securities sold is based on the specific
identification method.

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 that
is federally insured. While balances deposited often 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.  The
Company's  investment  policy  limits  investments  to  certain  types  of  debt  securities  issued  by  the  U.S.  government,  its
agencies  and  institutions  with  investment-grade  credit  ratings  and  places  restrictions  on  maturities  and  concentration  by
type and issuer. The counterparties are various corporations, financial institutions and government agencies of high credit
standing.

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.

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. Use of these inputs involves significant and subjective judgments to be
made by a reporting entity – e.g., determining an appropriate adjustment to a discount factor for illiquidity associated with
a given security.

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 valued at cost less accumulated depreciation. Depreciation is recognized on a straight-
line  basis  over  the  estimated  useful  lives  of  the  related  assets.  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.

99

Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

Estimated useful lives for property and equipment are as follows:

Computers and peripherals
Equipment
Furniture and fixtures
Leasehold improvements

Estimated Useful Life

3 years
5 years
7 years
  Lesser of estimated useful life or remaining lease term

The  Company  reviews  long-lived  assets,  which  primarily  consist  of  property  and  equipment,  for  impairment
whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be
fully recoverable based on the criteria for accounting for the impairment or disposal of long-lived assets under ASC Topic
360, Property, Plant and Equipment. These events or changes in circumstances may include a significant deterioration of
operating  results,  changes  in  business  plans,  or  changes  in  anticipated  future  cash  flows.  If  an  impairment  indicator  is
present,  the  Company  evaluates  recoverability  by  comparing  the  carrying  amount  of  the  assets  group  to  future
undiscounted net cash flows expected to be generated by the assets group. Assets are grouped at the lowest level for which
there is identifiable cash flows that are largely independent of the cash flows generated by other asset groups. If the total of
the expected undiscounted future cash flows is less than the carrying amount of the asset, an impairment loss is recognized
for the difference between the fair value and carrying value of assets within the group. Fair value is generally determined
by estimates of discounted cash flows. The discount rate used in any estimate of discounted cash flows would be the rate
required for a similar investment of like risk. No impairment losses were recognized during the years ended December 31,
2021 or 2020.

Construction  in  progress  (Note  5)  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.

Leases

The  Company  enters  into  lease  agreements  for  its  office  and  laboratory  facilities  and  accounts  for  them  in
accordance with ASC Topic 840, Leases. These leases are classified as operating leases. Rent expense is recognized on a
straight-line  basis  over  the  term  of  the  lease  and,  accordingly,  the  Company  records  the  difference  between  cash  rent
payments and the recognition of rent expense as a deferred rent liability. Incentives granted under the Company’s facilities
leases,  including  allowances  to  fund  leasehold  improvements,  are  deferred  and  are  recognized  as  adjustments  to  rental
expense on a straight-line basis over the term of the lease.

Preferred Stock

The Company did not have any outstanding preferred stock as of December 31, 2021 and 2020.

Research and Development Costs, Including Clinical Trial Accruals

Research costs consist of employee-related costs, contractor expenses, laboratory supplies and facility costs, for
research  and  development  of  product  candidates  are  expensed  as  incurred.  Development  costs,  including  clinical  trial-
related expenses, incurred by third parties, such as clinical research organizations (“CROs”), 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.
When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies, including the phase
or completion of events, invoices received and contracted costs.

Clinical  trial  expenses  are  a  significant  component  of  research  and  development  expenses,  and  the  Company
outsources a significant portion of these costs to third parties. Third-party clinical trial expenses include investigator fees,
site and patient costs, CRO costs, and costs for central laboratory testing and data management. The accrual for site and
patient costs includes inputs such as estimates of patient enrollment, patient cycles incurred, clinical site activations, and
other pass-through costs. These inputs are required to be estimated due to a lag in receiving the actual clinical information
from third parties. Payments for these activities are based on the terms of the individual arrangements, which may differ

100

    
 
 
 
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

from the pattern of costs incurred, and are reflected on the balance sheets as a prepaid asset or accrued expenses. These
third-party agreements are generally cancelable, and related costs are recorded as research and development expenses as
incurred. Non-refundable advance clinical payments for goods or services that will be used or rendered for future research
and development activities are recorded as a prepaid asset and recognized as expense as the related goods are delivered or
the related services are performed. When evaluating the adequacy of the accrued expenses, the Company analyzes progress
of the studies, including the phase or completion of events, invoices received and contracted costs. Significant judgments
and estimates may be made in determining the accrued balances at the end of any reporting period. Actual results could
differ from the estimates made. The historical clinical accrual estimates have not been materially different from the actual
costs.

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 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 because the Company has never paid dividends and has no current plans to pay any dividends on its
common  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”).

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 a liquidity event, such as the IPO or a sale, and the likelihood of such
an event.

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

101

Table of Contents

NOTES TO FINANCIAL STATEMENTS

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  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 as of December 31, 2021 and 2020.

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 accounts for revenue in accordance with 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  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
goods  or  services  promised  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

102

Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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 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 Income (Loss)

Comprehensive income (loss) is the change in equity of a business enterprise during a period from transactions
and other events and circumstances from non-owner sources. Comprehensive income (loss) includes net income (loss) and
the change in accumulated other comprehensive income (loss) for the period. Accumulated other comprehensive income
(loss) consisted entirely of unrealized gains and losses on available-for-sale marketable securities at December 31, 2021
and 2020.

Net Loss per Share

Basic loss per common share is determined by dividing loss attributable to common stockholders by the weighted-
average  number  of  common  shares  outstanding  during  the  period,  without  consideration  of  common  stock  equivalents.
Diluted  loss  per  share  is  computed  by  dividing  the  loss  attributable  to  common  stockholders  by  the  weighted-average
number  of  common  share  equivalents  outstanding  for  the  period.  The  treasury  stock  method  is  used  to  determine  the
dilutive effect of the Company's stock option grants.

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, which is generally consistent with required adoption dates of private companies.

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02 (Topic 842), Leases
(“ASC 842”). ASC 842 supersedes the lease recognition requirements in ASC 840, Leases. ASC 842 clarifies the definition
of a lease and requires lessees to recognize right-of-use assets and lease liabilities for all leases, including those classified
as operating leases under previous lease accounting guidance. For public entities, ASC 842 was effective for fiscal years
beginning after December 15, 2018, including interim periods within that year. As a result of the Company having elected
the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the
JOBS Act, ASC 842 will be effective for the Company on January 1, 2022. Originally, entities were required to adopt ASC
842 using a modified retrospective transition method. However, in July 2018, the FASB issued ASU 2018-11 (Topic 842),
Leases: Targeted Improvements, which provides entities with an additional transition method. Under ASU 2018-11, entities
have  the  option  of  initially  applying  ASC  842  at  the  adoption  date,  rather  than  at  the  beginning  of  the  earliest  period
presented  and  recognizing  the  cumulative  effect  of  applying  the  new  standard  as  an  adjustment  to  beginning  retained
earnings  in  the  year  of  adoption  while  continuing  to  present  all  prior  periods  under  previous  lease  accounting  guidance.
Based  on  its  current  lease  portfolio,  the  Company  estimates  the  adoption  of  ASC842,  using  the  transition  method,  will
result  in  approximately  $5.8  million  of  right-of-use  assets  and  $7.2  million  of  lease  liabilities  for  operating  leases  being
reflected  on  its  balance  sheet  as  of  January  1,  2022.    The  difference  between  these  amounts  will  be  comprised  of
adjustments related to unamortized balances of deferred rent, lease incentives, and prepaid rent existing as of the effective
date.  The  adoption  of  the  standard  is  not  expected  to  have  a  material  impact  on  its  statements  of  operations  and
comprehensive loss.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of
Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 will require credit losses to be reported using an
expected losses model rather than the incurred losses model that is currently used and will require additional disclosures
related to credit risks. For available-for-sale debt securities with unrealized losses, this standard will require allowances to
be recorded instead of reducing the amortized cost of the investment. ASU 2016-13 is effective for non-EGCs for fiscal
years beginning December 15, 2019, and interim periods within those fiscal years, and will be effective for the Company
for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, assuming the Company
remains an EGC. The Company adopted this standard early, effective January 1, 2021. The adoption of this standard did
not have a material impact on the Company’s financial statements.

The  Company  considers  the  applicability  and  impact  of  all  ASUs  issued  by  the  FASB.  All  other  ASUs  issued
subsequent to the filing of the Company’s Annual Report were assessed and determined to be either inapplicable or not
expected to have a material impact on the Company’s financial position or results of operations.

As  of  December  31,  2021,  no  marketable  securities  are  considered  to  be  other-than-temporarily  impaired.  The
Company uses the specific identification method when calculating realized gains and losses. For the years ended December
31, 2021 and 2020, respectively, the Company recorded $57 thousand and $70 thousand in realized gains on available-for-
sale securities, which is included in other income on the statements of operations and comprehensive loss.

The Company has classified all of its investments available-for-sale, including those with maturities beyond one
year, as current assets on the accompanying balance sheets based on the highly liquid nature of these investment securities
and because these investment securities are considered available for use in current operations.

4. Fair Value Measurements

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 as of December 31, 2021 and 2020:

7. Former 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  agreed  to  use  its
proprietary FIND-IO platform to identify novel oncology targets for additional collaborative research and drug discovery
by the Company and Lilly. Effective March 3, 2020, Lilly, terminated the Lilly Agreement without cause.

The  Company  recognized  revenue  under  the  Lilly  Agreement  of  $0  and  $22.4  million  for  the  years  ended
December  31,  2021  and  December  31,  2020,  respectively.  Effective  with  the  termination  of  the  agreement,  no  further
quarterly research and development support payments are payable to the Company.

Legal Proceedings

The  Company,  from  time  to  time,  is  a  party  to  litigation  or  legal  proceedings  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.

On September 21, 2020, a putative stockholder class action was filed in the U.S. District Court for the Southern
District of New York styled Ye Zhou v. NextCure, Inc., et. al., Case 1:20-cv-0772 (S.D.N.Y.). On February 26, 2021, the
Lead Plaintiff filed a consolidated amended complaint that asserts claims against us, certain of our officers and members of
our  board  of  directors,  and  the  underwriters  in  our  May  2019  initial  public  offering  and  November  2019  underwritten
secondary public offering. The complaint alleges that the defendants violated provisions of the Securities Exchange Act of
1934,  as  amended  (the  “Exchange  Act”),  and  the  Securities  Act  of  1933,  as  amended,  with  respect  to  statements  made
regarding  our  lead  product  candidate,  NC318,  and  the  FIND-IO  platform.  The  complaint  seeks  unspecified  damages  on
behalf  of  a  purported  class  of  purchasers  of  our  securities  between  May  8,  2019  and  July  14,  2020.  Defendants  filed  a
motion to dismiss the consolidated amended complaint on April 27, 2021, and discovery is stayed pending resolution of
that motion.

On March 24, 2021, a purported shareholder derivative lawsuit was filed in the U.S. District Court for the District
of Maryland, Southern Division, styled Zach Liu v. Richman et. al., Case:21-cv-00754, alleging breaches of fiduciary duty

107

    
 
 
 
 
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

by  officers  and/or  directors,  unjust  enrichment,  abuse  of  control,  gross  mismanagement,  waste  of  corporate  assets,  and
violations of the Exchange Act and the Securities Act of 1933. The Complaint seeks unspecified damages, attorneys’ fees
and  costs,  declaratory  relief,  corporate  governance  changes,  and  restitution.  On  May  17,  2021,  the  Court  granted  the
parties’ joint motion to stay the derivative lawsuit pending resolution of the Ye Zhou action’s motion to dismiss.

On December 14, 2021, a purported misappropriation of certain trade secrets lawsuit was filed in Federal District
Court for the District of Delaware, styled Immunaccel, LLC v. NextCure, Inc., Case No. 1:21-cv-01755-UNA. The lawsuit
alleges that the Company misappropriated certain trade secrets belonging to Immunaccel related to a drug discovery and
screening  platform  named  IMMUNE  3D.  The  complaint  alleges  two  causes  of  action,  one  under  the  Delaware  Uniform
Trade Secrets Act and another under the Federal Defend Trade Secrets Act, and seeks unspecified monetary damages, a
permanent injunction and other miscellaneous relief.

The Company intends to vigorously defend the Ye Zhou, Liu and Immunaccel actions. Based on the Company’s
assessment of the facts underlying these claims, the uncertainty of litigation, and the preliminary stage of these cases, the
Company cannot estimate the reasonably possible loss or range of loss that may result from these actions.

9. Term Loan

In April 2016, we entered into a $1.0 million term loan, or the “Term Loan”. In January 2019, we amended the
Term  Loan  to  increase  our  borrowing  capacity  to  $5.0  million,  which  amount  remains  secured  by  our  certificates  of
deposit, money market account, investment property and deposit or investment accounts. In August 2021, we fully paid the
remaining principal on the Term Loan, and there are no outstanding payments due from us.

10. Preferred Stock

As  of  December  31,  2021,  the  Company’s  certificate  of  incorporation,  as  amended  and  restated,  authorized  the
Company to issue 10,000,000 shares of $0.001 par value preferred stock, and there were no shares of preferred stock issued
or  outstanding.  The  Company  can  fix  the  price,  rights,  preferences,  privileges  and  restrictions  of  the  preferred  stock
without any further vote or action by its stockholders.

11. Common Stock

As of December 31, 2021, the Company’s Certificate of Incorporation, as amended and restated, authorized the
Company  to  issue  100,000,000  shares  of  $0.001  par  value  common  stock,  of  which  27,680,997  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 any preferred stock. No dividends have been declared or paid by the Company
through December 31, 2021.

In  the  event  of  any  liquidation  or  dissolution  of  the  Company,  the  holders  of  common  stock  are  entitled  to  the
remaining assets of the Company legally available for distribution after the payment of the full liquidation preference for
any preferred stock.

12. Stock-Based Compensation

Employee Equity Plans

The NextCure, Inc. 2015 Omnibus Incentive Plan (the “2015 Plan”) was adopted in December 2015 and provides
for  the  grant  of  awards  of  stock  options,  restricted  stock  awards,  unrestricted  stock  awards  and  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.

On  May  3,  2019,  the  Company’s  stockholders  approved  the  NextCure,  Inc.  2019  Omnibus  Incentive  Plan  (as
amended,  the  “2019  Plan”),  which  became  effective  on  May  8,  2019,  the  date  on  which  the  Company’s  Registration
Statement  on  Form  S-1  (Reg.  No.  333-230837)  was  declared  effective  (the  “Effective  Date”).  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  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  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 each January 1st 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 December 31, 2021, 2,313,433 shares were reserved for future issuance under the 2019 Plan.

Stock options granted under the 2015 Plan and 2019 Plan (together, the “Plans”) to employees generally vest over

four years and expire after 10 years.

A summary of stock option activity for awards under the Plans is presented below:

(1) The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options
and the fair value of the common stock for the options that were in the money at December 31, 2021 and 2020.

The weighted average grant date fair value per share of stock options granted during the years ended December
31, 2021 and 2020 was $7.47 and $23.25, respectively. The aggregate intrinsic value of stock options exercised during the
years ended December 31, 2021 and 2020 was $469,000 and $633,000, respectively.

The aggregate grant date fair value of stock options and restricted stock vested during the year ended December

31, 2021 and 2020 was approximately $13,398,000 and $2,389,000, respectively.

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 each January 1st 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. As of December 31, 2021, 6,464 shares of common stock had been issued pursuant to the ESPP and 784,216
shares were reserved for future issuance thereunder.

Stock-Based Compensation

The  Company  recorded  stock-based  compensation  expense  of  $10.3  million  and  $7.9  million  during  the  years
ended  December  31,  2021  and  2020,  respectively.  As  of  December  31,  2021,  there  was  $23.3  million  of  unrecognized
compensation  cost  related  to  unvested  stock-based  compensation  arrangements  granted  under  the  Plans.  This  remaining
compensation  expense  is  expected  to  be  recognized  over  a  weighted-average  period  of  three  years  as  of  December  31,
2021.

Stock-based  compensation  expense  recorded  as  research  and  development  and  general  and  administrative

13. Net Loss per Share Attributable to Common Stockholders

The Company’s potential dilutive securities, which 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 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:

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.

Based on the Company’s history of losses, the Company recorded a full valuation allowance against its deferred
tax assets as of December 31, 2021. The Company increased its valuation allowance by approximately $20.2 million for
the  year  ended  December  31,  2021.  The  Company  intends  to  maintain  a  valuation  allowance  until  sufficient  positive
evidence exists to support a reversal of the allowance.

As of December 31, 2021, the Company had federal and state net operating loss carryforwards of $160.9 million
and  $163.4  million,  respectively,  some  of  which  begin  to  expire  in  the  year  ending  December  31,  2036.  Approximately
$138.2 million of the federal net operating loss carryforwards do not expire. The Company had federal and state research
and development tax credit carryforwards of approximately $8.7 million and $0.1 million, respectively, as of December 31,
2021. 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”),  certain  substantial
changes in the Company’s ownership may have limited, or may limit in the future, the amount of net operating loss and
credit carryforwards that can be used to reduce future income taxes if there has been a significant change in ownership of
the  Company,  as  defined  by  the  IRC.  Future  owner  or  equity  shifts  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 2017
to 2020 remain open to examination by the major jurisdictions in which the Company is 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.

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,  2021,  the  Company  had  no  unrecognized  income  tax  benefits  that  would  affect  the  Company’s
effective tax rate if recognized.

The Coronavirus Aid, Relief, and Economic Security Act, or “CARES Act”, and the Consolidated Appropriations
Act, 2021, or “Stimulus Bill”, signed into law on March 27, 2020 and December 27, 2020, respectively, have resulted in
significant changes to the U.S. federal corporate tax law. Several states have also enacted tax legislation changes. We have

NOTES TO FINANCIAL STATEMENTS

considered  the  applicable  tax  law  changes  and  determined  there  was  no  significant  impact  to  the  tax  provision  of  the
Company.

15. Employee Benefit Plan

The Company sponsors a 401(k) plan which 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. For the years ended December 31, 2021 and 2020 the Company did not provide any contributions to this plan.

16. Subsequent Events

On  February  4,  2022,  the  Company  entered  into  a  Third  Amendment  to  its  original  Lease  Agreement,  dated

January 30, 2019, whereby the Company has expanded its leased property by approximately 5,700 square feet.

RE: EXECUTIVE EMPLOYMENT AGREEMENT

Dear Dr. Myint:

On  behalf  of  NextCure,  Inc.  (“NextCure”,  or  the  “Company”),  it  is  my  pleasure  to  confirm  the  terms  and
conditions  on  which  the  Board  of  Directors  of  NextCure  (the  “Board”)  and  you  have  agreed  that  you  will
continue your employment with the Company, serving as the Company’s Chief Medical Officer, reporting to the
Company’s  Chief  Executive  Officer,  effective  as  of  January  11,  2021  (the  “Start  Date”).    During  your
employment  with  NextCure,  you  will  devote  substantially  all  of  your  professional  efforts  to  the  business  of
NextCure,  except  that  you  may  engage  in  the  business  activities  described  on  Appendix  A  of  this  employment
agreement  (this  “Agreement”),  and  other  activities  that  may  be  approved  in  advance  by  the  Company’s  Chief
Executive Officer, with advice from the Board (which may include the for-profit board membership(s) described
on Appendix A), in each case, so long as these activities do not interfere or conflict with your obligations to the
Company.  Your employment under the terms of this Agreement shall continue until it terminates in accordance
with Section 5 below.

This Agreement supersedes, amends and restates in all respects all prior agreements and understandings between
you and the Company regarding the subject matter herein.

This Agreement is intended to summarize some of the terms and conditions of your employment.

1.

Location.  Your place of employment will be at NextCure’s principal offices, currently located in

Beltsville, Maryland.

2.

Compensation.

a.

Base  Salary.    Your  initial  annualized  base  salary  rate  will  be  $425,000,  less  standard
deductions and withholding and payable bi-weekly in accordance with NextCure’s regular payroll practices.  Your
salary shall be reviewed annually and may be adjusted in connection with any such review.

b.

Housing  Allowance.    Upon  your  Start  Date,  you  were  provided  with  a  special,  one-time
bonus in the amount of $75,000 to cover relocation and housing expenses resulting from your move from New
Jersey to Maryland, to be used at your discretion. If you should voluntarily terminate your employment prior to
the 24-month anniversary of your Start

Date, then you will pay NextCure a ratable portion of this bonus based on the number of months remaining in this
24-month period.

c.

Bonus Program.  You will be eligible for an annual target bonus of 40% of your annual base
salary as determined by the Board in its sole discretion based upon, among other things, the achievement of pre-
determined performance milestones.  Any annual bonus, if earned, shall be paid no later than March 15th of the
year immediately following the year to which the applicable annual bonus relates.

d.

Option  Grants.    As  of  your  Start  Date,  you  were  granted  an  option  to  purchase  200,000
shares of NextCure’s common stock, vesting 25% on the first anniversary of your Start Date, and thereafter in 36
equal, monthly installments until fully-vested, on the fourth anniversary of your Start Date.  The option grant is
subject to the terms of NextCure’s equity incentive arrangements, including its customary Incentive Stock Option
(ISO) Grant Agreement.

e.

Withholding.  NextCure shall withhold from any compensation or benefits payable to you
by NextCure any federal, state and/or local income, employment and/or other similar taxes as may be required to
be withheld pursuant to any applicable law or regulation.

3.

Benefits.

a.

Vacation and Holidays.  You will be eligible each year for 10 paid vacation days (excluding
federal holidays), 2 paid personal days and 8 paid days of sick time, as well as paid time off from December 28
through December 30.

b.

Other.  You will be eligible to participate in the benefits to be offered by NextCure on the
same  terms  and  conditions  as  it  will  make  such  benefits  available  to  employees  in  positions  similar  to  your
position.    The  benefits  are  currently  expected  to  include  health  insurance  and  such  other  benefits  provided  by
similar companies of a similar stage, as approved by the Board.

c.

Expenses.  NextCure shall reimburse you for all reasonable expenses of the type authorized
by NextCure and incurred by you in the performance of your duties under this Agreement, all in accordance with
the Company’s reimbursement policies.

As is the case of all employee benefits, such benefits will be governed by the terms and conditions of applicable
NextCure plans or policies, which are subject to change or discontinuation at any time.

4.

Severance.

a.

prior to the year in which termination of employment occurs; (iii) reimbursement of any unreimbursed business
expenses  incurred  as  of  the  date  of  termination  of  employment  in  accordance  with  NextCure’s  reimbursement
policy, (iv) accrued  but  unused  vacation  (if  applicable),  earned  through  the  date of termination of employment;
and (v) all other payments, benefits or fringe benefits to which you shall be entitled under the terms of any

2

applicable  compensation  arrangement  or  benefit,  equity  or  fringe  benefit  plan  or  program  or  grant  with  or  by
NextCure or this Agreement.

ii.

“Cause” means conduct involving one or more of the following by you: (i) failure
to perform a substantial portion of your duties and responsibilities in accordance with the terms or requirements of
this Agreement and your position, which failure continues for, or is not permanently cured within, a period of 60
days  after  written  notice  given  to  you  by  NextCure  except  in  the  case  of  your  physical  or  mental  illness;  (ii)
disloyalty,  gross  negligence,  willful  misconduct,  or  dishonesty  that  materially  injures  NextCure  or  breach  of
fiduciary duty to NextCure; (iii) the conviction of (x) a felony or (y) a misdemeanor involving moral turpitude, or
fraud;  (iv)  the  commission  of  an  act  of  embezzlement  or  fraud;  or  (v)  the  material  breach  of  any  agreement
between NextCure and you.

iii.

“Good Reason” means, without your express written consent, (i) any reduction in
your annual base salary other than a reduction which is proportional to general reductions affecting other senior
executive  officers  of  NextCure  generally,  (ii)  any  material  reduction  in  your  title  or  scope  of  responsibilities
without  your  consent  (other  than  your  removal  from  the  Board);  or  (iii)  a  requirement  that  the  location  of  the
office  in  which  you  perform  your  principal  duties  for  NextCure  be  changed  to  a  new  location  that  is  outside  a
radius of 50 miles from the Company’s corporate headquarters in Beltsville, Maryland.

b.

Severance Benefits and Payment.

i.

Generally.  If your employment with NextCure is terminated by NextCure for any
reason other than Cause or by you for Good Reason, NextCure will pay you (1) the Accrued Benefits; (2) subject
to  your  compliance  with  Section 4(c)  below,  after  the  execution  and  delivery  of  the  Separation  Agreement  and
General Release in the form attached hereto as Appendix B (the “Separation Agreement and General Release”)
and the expiration of any revocation period without the release being revoked, 9 months’ base salary, less standard
deductions, payable in a single lump sum on the 60th day following the termination of your employment; and (3)
if you elect to continue your health insurance coverage pursuant to your rights under the Consolidated Omnibus
Budget  Reconciliation  Act  of  1985,  as  amended  (“COBRA”),  following  the  termination  of  your  employment,

termination date, or (y) the date upon which you commence full-time employment (or employment that provides
you  with  eligibility  for  healthcare  benefits  substantially  comparable  to  those  provided  by  NextCure).    A
termination  of  your  employment  by  NextCure  due  to  physical  or  mental  illness  which  is  not  a  Disability  (as
defined herein) shall be treated as an involuntary termination other than for Cause.  The term “Disability” shall
mean  that  you  have  not  been  able  to  materially  engage  in  your  duties  and  responsibilities  by  reason  of  any
medically determinable physical or mental impairment for a period of not less than 120 consecutive days or not
less than 180 days during any one-year period.

ii.

In  connection  with  the  Change  in  Control  Period.    If  your  employment  with

Change in Control Period, NextCure will pay you (1) the Accrued Benefits; (2) subject to your compliance with
Section 4(c) below, after the execution

3

and  delivery  of  the  Separation  Agreement  and  General  Release  and  the  expiration  of  any  revocation  period
without the release being revoked, 12 months’ base salary plus your annual target bonus, less standard deductions,
payable in a single lump sum on the 60th day following the termination of your employment; and (3) if you elect
to  continue  your  health  insurance  coverage  pursuant  to  your  rights  under  COBRA  following  the  termination  of
your employment,  your  monthly  premium  under  COBRA  on  a  monthly  basis  until  the  earlier  of  (x)  12  months
following  the  effective  termination  date,  or  (y)  the  date  upon  which  you  commence  full-time  employment  (or
employment that provides you with eligibility for healthcare benefits substantially comparable to those provided
by NextCure).  A termination of your employment by NextCure due to physical or mental illness which is not a
Disability shall be treated as an involuntary termination other than for Cause.

c.

Eligibility for Severance.  Eligibility for receipt of the items in Section 4(b)(ii)  above shall
be  conditioned  on  your  (i)  returning  to  NextCure  promptly  upon  termination  of  your  employment  all  of  its
property,  including  confidential  information  and  all  electronically  stored  information,  and  (ii)  signing  and  not
revoking the Separation Agreement and General Release.

d.

Accrued Benefits.  The Accrued Benefits shall be paid to you (or your estate in the event of

your death) upon termination of employment regardless of the circumstances giving rise to such termination.

that this Agreement is not a contract for employment for a definite term.

Confidentiality  and  Proprietary  Rights  Agreement.    This  offer  of  employment  is  subject  to  the
Confidentiality and Proprietary Rights Agreement attached as Appendix C, which shall be effective as of the date
set forth therein.

7.

No Inconsistent Obligations.  By accepting this offer of employment, you represent and warrant to
NextCure  that  you  are  under  no  obligations  or  commitments,  whether  contractual  or  otherwise,  that  are
inconsistent with your obligations set forth in this Agreement or that would be violated by your employment by
NextCure.   You  agree  that  you  will  not  take  any  action  on  behalf  of  NextCure  or  cause  NextCure  to  take  any
action that will violate any agreement that you have with a prior employer.

8.

Delayed Commencement Date for Payments and Benefits.

a.

The intent of the parties hereto is that payments and benefits under this Agreement comply
with, or be exempt from, Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations
and  guidance  promulgated  thereunder  (collectively  “Code  Section  409A”)  and,  accordingly,  to  the  maximum
extent permitted, this Agreement shall be interpreted to be in compliance therewith or exempt therefrom.  If you
notify NextCure (with specificity as to the reason therefor) that you believe that any provision of this Agreement
(or of any award of compensation, including equity compensation or benefits) would cause you to incur

4

any  additional  tax  or  interest  under  Code  Section  409A  and  NextCure  concurs  with  such  belief  or  NextCure
independently makes such determination, NextCure shall, after consulting with you, reform such provision to try
to  comply  with  Code  Section  409A  through  good  faith  modifications  to  the  minimum  extent  reasonably
appropriate to conform with Code Section 409A. To the extent that any provision hereof is modified in order to
comply with Code Section 409A, such modification shall be made in good faith and shall, to the maximum extent
reasonably  possible,  maintain  the  original  intent  and  economic  benefit  to  you  and  NextCure  of  the  applicable
provision without violating the provisions of Code Section 409A.

b.

A  termination  of  employment  shall  not  be  deemed  to  have  occurred  for  purposes  of  any
provision  of  this  Agreement  providing  for  the  payment  of  any  amounts  or  benefits  upon  or  following  a
termination of employment that are considered “nonqualified deferred compensation” under Code Section 409A
unless  such  termination  is  also  a  “separation  from  service”  within  the  meaning  of  Code  Section  409A  and,  for
purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or
like terms shall mean “separation from service.” Notwithstanding any provision to the contrary in this Agreement,
no payments or benefits that are considered “nonqualified deferred compensation” under Code Section 409A to
which you otherwise become entitled under this Agreement in connection with your termination of employment,
shall be made or provided to you prior to the earlier of (i) the expiration of the 6 month period measured from the
date of your “separation from service” with NextCure (as such term is defined in Code Section 409A) or (ii) the
date of your death, if you are deemed at the time of such separation from service to be a “specified employee”
under Code Section 409A and if, in the absence of such delay, the payments would be subject to additional tax
under  Code  Section  409A.  Upon  the  expiration  of  the  applicable  Code  Section  409A(a)(2)  deferral  period,  all
payments and benefits deferred pursuant to this Section 8(b) (whether they would have otherwise been payable in
a single sum or in installments in the absence of such deferral) shall be paid or reimbursed to you in a lump sum,
and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with
the normal payment dates specified for them herein.

c.

For purposes of Code Section 409A, your right to receive any installment

payment  pursuant  to  this  Agreement  shall  be  treated  as  a  right  to  receive  a  series  of  separate  and  distinct
payments.  Whenever a payment under this Agreement specifies a payment period with reference to a number of
days (e.g., “payment shall be made within 30 days following the date of termination”), the actual date of payment
within the specified period shall be within the sole discretion of NextCure.  Notwithstanding any other provision
of  this  Agreement  to  the  contrary,  in  no  event  shall  any  payment  under  this  Agreement  that  constitutes
“nonqualified  deferred  compensation”  for  purposes  of  Code  Section  409A  be  subject  to  offset,  counterclaim  or
recoupment by any other amount payable to you unless otherwise permitted by Code Section 409A.

d.

All  in-kind  benefits  provided  and  expenses  eligible  for  reimbursement  under  this
Agreement shall be provided by NextCure or incurred by you during the time periods set forth in this Agreement.
 All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement
be paid after the last day of the taxable year following the taxable year in which the expense was incurred.  The
amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-
kind benefits

5

to be provided or the expenses eligible for reimbursement in any other taxable year.  Such right to reimbursement
or in-kind benefits is not subject to liquidation or exchange for another benefit.

e.

If under this Agreement an amount is to be paid in installments, each installment shall be

treated as a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii).

9.

280G.  In the event that the amount of any compensation, payment or distribution by NextCure or
its affiliates to or for your benefit, whether paid or payable or distributed or distributable pursuant to the terms of
this Agreement or otherwise, calculated in a manner consistent with Section 280G of the Code and the applicable
regulations thereunder (the “Aggregate Payments”) would be subject to the excise tax imposed by Section 4999
of  the  Code,  then  the  Aggregate  Payments  shall  be  reduced  (but  not  below  zero)  so  that  the  sum  of  all  of  the
Aggregate Payments shall be $1.00 less than the amount at which you become subject to the excise tax imposed
by Section 4999 of the Code; provided that such reduction shall only occur if it would result in you receiving a
higher After Tax Amount (as defined below) than you would receive if the Aggregate Payments were not subject
to such reduction.  In such event, the Aggregate Payments shall be reduced in the following order, in each case, in
reverse chronological order beginning with the Aggregate Payments that are to be paid the furthest in time from
consummation  of  the  transaction  that  is  subject  to  Section  280G  of  the  Code:  (i)  cash  payments  not  subject  to
Section 409A of the Code; (ii) cash payments subject to Section 409A of the Code; (iii) equity-based payments
and  acceleration;  and  (iv)  non-cash  forms  of  benefits;  provided  that  in  the  case  of  all  the  foregoing  Aggregate
Payments all amounts or payments that are not subject to calculation under Treas. Reg. § 1.280G-1, Q&A-24(b) or
(c)  shall  be  reduced  before  any  amounts  that  are  subject  to  calculation  under  Treasury  Regulation  §1.280G-1,
Q&A- 24(b) or (c).  For purposes of this Section 9, the “After Tax Amount” means the amount of the Aggregate
Payments less all federal, state, and local income, excise and employment taxes imposed on you as a result of your
receipt of the Aggregate Payments.  For purposes of determining the After Tax Amount, you shall be deemed to
pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the
calendar year in which the determination is to be made, and state and local income taxes at the highest marginal
rates of individual taxation in each applicable state and locality, net of the maximum reduction in federal income
taxes which could be obtained from deduction of such state and local taxes.  The determination as to whether a
reduction  in  the  Aggregate  Payments  shall  be  made  pursuant  to  this  Section  9  shall  be  made  by  a  nationally
recognized accounting firm or a firm specializing in Section 280G calculations selected by NextCure, which shall
provide detailed supporting calculations both to NextCure and you.  The costs of obtaining such determination and
all related fees and expenses (including related fees and expenses incurred in any later audit) shall be borne by
NextCure.    Notwithstanding  the  foregoing,  if  (i)  NextCure  is  not  publicly  traded  prior  to  the  occurrence  of  a
change in control such that the private company exception pursuant to Q & A #7 of the regulations promulgated
under Section 280G of the Code is applicable and (ii) you request that NextCure seek shareholder approval of the
portion of any payments to be made to you which are parachute payments under Section 280G and exceed 2.99
times your “base amount” (as such term is defined in Section 280G) in order that, upon obtaining such approval,
all of the payments will be exempt from the excise taxes imposed

6

under Sections 280G and 4999 of the Code, NextCure shall use its reasonable best efforts to obtain such approval.

Delivery of 2022 Expansion Premises. Landlord shall use reasonable efforts to deliver the 2022 Expansion Premises
to Tenant on July 1, 2022 in their vacant, “as is” (but broom clean) condition as more fully described in Section 4.a.(i) below (“Delivery”
or “Deliver”).  The  date  on  which  Landlord  Delivers  the  2022  Expansion  Premises  to  Tenant  is  referred  to  as  the  “2022  Expansion
Premises Commencement Date.” Upon request of Landlord, Tenant shall execute and deliver a written acknowledgement of the 2022
Expansion  Premises  Commencement  Date  when  it  is  established  in  the  form  attached  hereto  as  Exhibit  B;  provided,  however,  that
Tenant’s  failure  to  execute  and  deliver  such  acknowledgement  shall  not  affect  Landlord’s  rights  under  this  Third  Amendment  or  the
Lease. If Landlord fails to Deliver timely the 2022 Expansion Premises, Landlord shall not be liable to Tenant for any loss or damage
resulting therefrom, and this Third Amendment and the Lease with respect to the 2022 Expansion Premises shall not be void or voidable.

a. Except  as  set  forth  in  this  Third  Amendment,  if  applicable:  (i)  Landlord  shall,  at  its  expense,  Deliver  the  2022
Expansion  Premises  to  Tenant  with  the  interior  of  the  2022  Expansion  Premises  demolished  to  the  exterior  walls
leaving in place only the main HVAC trunk lines and the 2 rooftop HVAC units serving the 2022 Expansion Premises
(collectively, “Demolition Work”), (ii) Tenant shall accept the 2022 Expansion Premises in such condition as of the
2022  Expansion  Premises  Commencement  Date,  (iii)  Landlord  shall  have  no  obligation  for  any  defects  in  the  2022
Expansion Premises, and (iv) Tenant’s taking possession of the 2022 Expansion Premises shall be conclusive evidence
that Tenant accepts the 2022 Expansion Premises and that the 2022 Expansion Premises were in good condition at the
time possession was taken.

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 2022 Expansion Premises, and/or the suitability of the 2022 Expansion Premises for the conduct of
Tenant’s  business,  and  Tenant  waives  any  implied  warranty  that  the  2022  Expansion  Premises  are  suitable  for  the
Permitted  Use.  Tenant  shall  use  the  2022  Expansion  Premises  only  for  the  Permitted  Use  under  the  Lease  in
compliance with the provisions of Section 7 of the Lease.

c. Except for Landlord’s performance of the Demolition Work and as set forth in this Section 5, Landlord shall have no
obligation to perform any work at the Building in connection with Tenant’s occupancy of the 2022 Expansion Premises
or obtain any permits, approvals, or entitlements related to Tenant’s specific use of the 2022 Expansion Premises or
Tenant’s business operations therein.

d. As of the Effective Date, Landlord is leasing the 2022 Expansion Premises to [***] LLC, a Maryland limited liability
company (“[***]”),  and  the  lease  agreement  (“[***] Lease”)  between  Landlord  and  [***]  is  scheduled  to  expire  on
October  31,  2023.  This  Third  Amendment  is  contingent  on  Landlord  and  [***]  agreeing  in  writing  to  terminate  the
[***] Lease and [***] vacating the 2022 Expansion Premises on or before May 31, 2022 (“Termination Agreement”),
which  Termination  Agreement  shall  be  on  terms  and  conditions  acceptable  to  Landlord  in  its  sole  and  absolute
discretion (“Contingency”).  Landlord  will  notify  Tenant  promptly  of  the  execution  and  delivery  of  the  Termination
Agreement. Tenant acknowledges that Landlord makes no promise, guaranty, or assurance that it will be able to enter
into  the  Termination  Agreement  and,  as  a  result,  Landlord  makes  no  guaranty,  representation,  or  assurance  that
Landlord  will  be  able  to  Deliver  the  2022  Expansion  Premises  to  Tenant  by  the  2022  Expansion  Premises
Commencement Date and that Landlord shall have no obligation or duty to seek the vacation or removal of [***] from
the 2022 Expansion Premises. If Landlord is unable to

Deliver the 2022 Expansion Premises on or before August 31, 2022, Tenant shall have the right to terminate this Third
Amendment  by  sending  written  notice  thereof  to  Landlord  by  no  later  than  September  15,  2022,  whereupon  neither
Landlord nor Tenant shall have any further rights, duties, or obligations under this Third Amendment. If Tenant does
not elect to so terminate this Third Amendment by September 15, 2022, such right to terminate this Third Amendment
shall be waived.

e. Tenant, at its sole expense, shall make any alterations or modifications to the interior of the 2022 Expansion Premises
that  are  required  by  Legal  Requirements  (including,  without  limitation,  compliance  of  the  2022  Expansion  Premises
with the ADA).

f. Notwithstanding  any  contrary  provision  contained  in  this  Section  5,  Tenant  shall  have  a  period  of  60  days  after
Landlord’s Delivery of the 2022 Expansion Premises to Tenant to reasonably identify in writing any latent defects in
the mechanical, electrical, and plumbing systems and the structural components serving the 2022 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 such identified latent defects (subject to Landlord’s reasonable
confirmation that such defects are, in fact, latent defects).

6.

Base  Rent  for  2022  Expansion  Premises.  (a)  Tenant  shall  continue  to  pay  Base  Rent  with  respect  to  the  Existing
Premises  and  the  Expansion  Premises  at  the  rates  set  forth  in  the  Lease,  (b)  commencing  on  the  2022  Expansion  Premises
Commencement Date (but subject to the 2022 Expansion Premises Base Rent Abatement [as defined below]), Base Rent for the 2022
Expansion  Premises  shall  be  payable  at  the  rate  of  $  [***]  per  month,  and  (c)  commencing  on  the  2022  Expansion  Premises
Commencement Date, Base Rent for the 2022 Expansion Premises shall be increased as of the date or dates on which Tenant uses the
Additional 2022 Expansion Premises TI Allowance (as defined in the 2022 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 2022 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  2022  Expansion  Premises).  Notwithstanding  any  contrary
provision contained in the Lease, the Base Rent for the 2022 Expansion Premises shall thereafter be increased on each anniversary of the
2022  Expansion  Premises  Commencement  Date  by  multiplying  the  Base  Rent  payable  for  the  2022  Expansion  Premises  immediately
before such date by the Rent Adjustment Percentage (i.e., [***]%) and adding the resulting amount to the Base Rent payable for the 2022
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  2022  Expansion  Premises  TI  Allowance.  Base  Rent  for  the  2022  Expansion
Premises, as so adjusted, shall thereafter be due as provided in the Lease.

a.

2022 Expansion Premises Base Rent Abatement. Notwithstanding anything to the contrary contained in this
Third Amendment, but provided Tenant is not in Default hereunder or under the Lease, Landlord hereby grants Tenant an abatement of
the Base Rent payable for the 2022 Expansion Premises during the period beginning on the 2022 Expansion Premises Commencement
Date and ending [***] after the 2022 Expansion Premises Commencement Date (“2022 Expansion Premises Base Rent Abatement”).
For the avoidance of doubt, if the 2022 Expansion Premises Commencement Date occurs on the first day of a month, the 2022 Expansion
Premises Base Rent Abatement will be measured from that date. If the 2022 Expansion Premises Commencement Date occurs on a day
other than the first day of a month, the 2022 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  for  the  2022
Expansion  Premises  in  accordance  with  the  provisions  of  this  Third  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 2022 Expansion Premises
that would have been payable but for the 2022 Expansion Premises Base Rent Abatement. Notwithstanding anything to the contrary in
this Section 6(a), the adjustment in the Base Rent as set forth in this Section 6 shall be based on the full and unabated amount of Base
Rent  payable  with  respect  to  the  2022  Expansion  Premises  for  the  first  [***]  period  from  and  after  the  2022  Expansion  Premises
Commencement Date.

7.

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, the Expansion Premises TI Allowance
as  described  in  the  First  Amendment,  and  the  2022  Expansion  Premises  TI  Allowance  as  described  in  Section 5  of  the  Work  Letter
attached to this Third Amendment, but may include build-out allowances to the extent they are then provided as market concessions in
the Market Area.

8.

Amendment to Section 20(h). Section 20(h) of the Lease, captioned “Work Letter and 9000 VMR Work Letter,” is

hereby deleted and replaced with the following new Section 20(h):

Work Letter, Expansion Premises Work Letter, 2022 Expansion Premises Work Letter, and 9000 VMR
(h)
Work Letter. Tenant fails to perform any obligation imposed on it under the terms and conditions of the Work Letter,
the  Expansion  Premises  Work  Letter,  the  2022  Expansion  Premises  Work  Letter,  or  the  9000  VMR  Work  Letter  (as
applicable), which failure is not cured within any applicable notice and cure period specifically set forth in the Work
Letter, the Expansion Premises Work Letter, the 2022 Expansion Premises Work Letter, or the 9000 VMR Work Letter,
as applicable.

9.

Amendment to Section 21(f). Section 21(f) of the Lease, captioned “Suspension of Funding,” is hereby deleted and

replaced with the following new Section 21(f):

Suspension of Funding. Upon a Default by Tenant hereunder and during the continuance thereof, Landlord
(f)
shall  have  the  right  to  suspend  funding  of  any  TI  Allowance,  the  Expansion  Premises  TI  Allowance,  and  the  2022
Expansion Premises TI Allowance.

10.

Amendment to Section 30(a). Section 30(a) of the Lease, captioned “Prohibition/Compliance/Indemnity,” is hereby

amended by deleting the proviso and replacing it with the following new proviso:

; provided, however, that Tenant shall have no indemnification, remediation, or other obligation or responsibility under
this Section 30 for any contamination or Environmental Claim if Tenant proves by a preponderance of the evidence
that such contamination or Environmental Claim arises from any Hazardous Materials brought into, kept, used, stored,
handled,  treated,  generated  in  or  about,  or  released  or  disposed  of  from  the  Premises  by  Landlord  or  another  tenant
unrelated  or  unaffiliated  with  Tenant  or  that  existed  in  the  Existing  Premises  as  of  the  Commencement  Date,  in  the
Expansion Premises as of the Expansion Premises Commencement Date, or in the 2022 Expansion Premises as of the
2022  Expansion  Premises  Commencement  Date,  and  were  not  brought  into,  kept,  used,  stored,  handled,  treated,
