vary  materially  from  any  future  results,  activity,  performance,  or  achievements  expressed  or  implied  by  these  forward-
looking statements.

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.
● Recently announced interim results regarding our NC318 monotherapy Phase 1/2 clinical trial may adversely impact

our product development efforts.

● 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 NC318's 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 encounter difficulties enrolling patients in our clinical trials.
● 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 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.

4

Table of Contents

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.

● 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 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.

● 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 negative evaluations of

our stock, 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 that act by new or unique mechanisms.

Our  lead  product  candidate,  NC318,  is  a  first-in-class  immunomedicine  targeting  a  novel  immunomodulatory
receptor  called  Siglec-15,  or  S15.  We  are  currently  evaluating  NC318  for  the  treatment  of  advanced  or  metastatic  solid
tumors,  including  head  and  neck  squamous  cell  carcinoma,  or  HNSCC,  and  triple-negative  breast  cancer,  or  TNBC.  In
October  2018,  we  initiated  the  Phase  1  portion  of  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 in November 2019 at the Society for Immunotherapy of Cancer, or SITC, annual
meeting. Data from the trial indicated activity in multiple tumor types, including a complete response and a partial response
in patients with non-small cell lung cancer, or NSCLC, and durable stable disease in patients with NSCLC, endometrial
cell cancer, ovarian cancer, squamous cell carcinoma, Merkel cell cancer, and head and neck cancer. We began enrolling
patients in the Phase 2 portion of the trial in October 2019. In the Phase 2 portion, patients were initially selected based on
tumors with a PD-L1 tumor proportion score, or TPS, of less than 50%. In July 2020, we announced a confirmed partial
response in a head and neck squamous cell carcinoma patient. In addition, we reported that at that time we did not plan to
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.  Of  the  evaluable  biopsies  collected,  13%  of  the  patients  enrolled  had  S15-positive  tumors.  These  biopsies
showed  that  the  selection  criterion  did  not  result  in  enough  S15-positive  patients  to  effectively  evaluate  the  activity  of
NC318 in S15-positive tumors. We are modifying the Phase 2 portion of the trial for S15 selection and expect to begin pre-
selecting patients for enrollment based on S15 expression in the second quarter of 2021, which we anticipate will allow us
to assess response rates in patients selected for S15 positivity. As of December 2020, NC318 continued to be well tolerated
in the Phase 2 portion of the trial, with primarily mild or moderate treatment-related adverse events, or TRAEs. The only
observed severe or higher grade TRAE in the Phase 2 portion was a grade 3-4 infusion reaction in one patient. While we no
longer plan to initiate a study of NC318 in combination with chemotherapy in lung cancer patients at this time, we believe
that  scientific  evidence  supports  studying  a  combination  of  NC318  with  an  anti-PD-1  therapy.  In  the  second  quarter  of
2021, Yale plans to initiate a Phase 2 Investigator-Initiated, or IIT, of NC318 as a monotherapy and in combination with
pembrolizumab, an anti-PD-1, in NSCLC patients.

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

Our  second  product  candidate,  NC410,  is  a  novel  immunomedicine  designed  to  block  immune  suppression
mediated  by  an  immune  modulator  called  Leukocyte-Associated  Immunoglobulin-like  Receptor  1,  or  LAIR-1.  The  U.S.
Food and Drug Administration, or FDA, accepted our investigational new drug application, or IND, for NC410 in the first

6

Table of Contents

quarter of 2020, and we initiated the Phase 1 portion of a Phase 1/2 clinical trial in patients with advanced or metastatic
solid tumors in June 2020 after a temporary delay due to the COVID-19 pandemic. Initial Phase 1 data are expected to be
reported in the second half of 2021.

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

Our  third  product  candidate,  NC762,  is  an  immunomedicine  targeting  a  molecule  called  human  B7  homolog  4
protein, or B7-H4. We submitted an IND to the FDA for NC762 in the first quarter of 2021, and we intend to initiate a
Phase 1/2 clinical trial in patients with lung cancer, HER2+ breast cancer, ovarian cancer and potentially other tumor types
in the second quarter of 2021.

NC762 is a monoclonal antibody that binds specifically to B7-H4, a protein expressed on multiple tumor types.
We  believe  NC762  has  unique  anti-tumor  properties  and  acts  by  inhibiting  tumor  cell  growth  and  killing  tumor  cells,
including by enhancing the immune response. 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. Our research
indicates that NC762 inhibits tumor cell growth independently of immune cell infiltration in the TME, but that NK cells
may contribute to enhanced anti-tumor activity mediated by NC762.

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.

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

Members of our management team have a longstanding relationship with our scientific founder Dr. Chen, who is

Dr. Chen was the first to discover PD-L1, and to show that it is expressed by multiple tumor types and its activity can cause
the death of T cells, preventing those T cells from eliminating cancer cells. He also showed that blocking the interaction
between  PD-1  and  PD-L1  with  monoclonal  antibodies  improved  the  immune  system’s  ability  to  eliminate  tumors.  Dr.
Chen’s work provided an important foundation for the subsequent development of immunotherapies that

enable more effective immune treatments against cancer. We continue to collaborate with Dr. Chen on discovering novel
immunomedicines through an exclusive sponsored research agreement with Yale.

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 plans to initiate a Phase 2 IIT of that combination in
NSCLC patients in the second quarter of 2021. For NC410, the FDA accepted our IND in the first quarter of
2020 and we initiated the Phase 1 portion of a Phase 1/2 clinical trial in June 2020. For NC762, we submitted
our IND in the first quarter of 2021, and we intend to initiate a Phase 1/2 clinical trial in the second quarter of
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.  In  addition  to  our  internal  discovery  efforts,  we  also  seek  to
leverage  our  relationship  with  Dr.  Chen’s  laboratory  at  Yale  for  the  discovery  of  additional  targets  for
immunomedicines.

● 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,
dedicated, state-of-the-art cGMP manufacturing facility utilizes single-use technology to support

8

Table of Contents

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.

● 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.  For  example,  we  are  developing  our  FIND-AI  platform,  a  new
platform focused on discovery efforts in autoimmunity and inflammation.

● 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 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 cellular types over time in order to
identify novel targets that either increase or decrease immune-related functional responses associated with desired immune
responses  against  tumors.  By  identifying  novel  immune  modulators  through  the  FIND-IO  platform,  we  aim  to  develop
next-generation immunomedicines that restore normal immune function in the TME.

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

Our  FIND-IO  technology  includes  proprietary  approaches  to  functionally  assess  immune  pathways  in  both
primary immune cells and established cell lines from immune lineages, including T cell subsets, monocytes, macrophage
subpopulations,  dendritic  cells,  cancer  cell  lines  and  cells  isolated  from  diseased  patients.  This  platform  allows  us  to
identify  proteins  that  can  be  targeted  with  novel  immunomedicines  to  repair  and  maintain  anti-tumor  immunity.  By
focusing  on  understanding  the  TME  in  oncology,  we  believe  we  can  identify  multiple  new  positive  and  negative
modulators of immune cells, including T cells, NK cells, macrophages and myeloid-derived suppressor cells.

As  shown  in  the  figure  below,  our  product  candidates  target  a  variety  of  cell  types  in  the  immune  system.  For
example, NC318 targets macrophages and tumor cells and prevents suppressive myeloid cells from negatively regulating T
cells, 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. In the Phase 2 portion, patients were initially selected based on tumors with a PD-L1 TPS of less than 50%. In April
2020, we announced that given enrollment slowdown due to the COVID-19 pandemic, we expected initial data from the
Phase 2 portion of the Phase 1/2 monotherapy trial to be temporarily delayed. However, we continued to support ongoing
activities for patients enrolled in the trial and to work with our clinical sites to enroll new patients as appropriate.

In July 2020, we reported a confirmed partial response in a head and neck squamous cell carcinoma 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 at the time of initial screening of patients in the Phase 2 portion of our NC318 trial. Of the evaluable biopsies
collected, 13% of the patients enrolled had S15-positive tumors. These biopsies showed that the selection criterion did not
result in enough S15-positive patients for us to effectively evaluate the activity of NC318 in S15-positive tumors. We are
modifying  the  ongoing  Phase  2  portion  of  the  trial  for  S15  selection  and  expect  to  begin  pre-selecting  patients  for
enrollment  based  on  S15  expression  in  the  second  quarter  of  2021  after  the  assay  we  have  selected  for  evaluating  S15
expression has been validated under the Clinical Laboratory Improvements Amendment, or CLIA. We anticipate the assay
and the selection of S15 positive patients will allow us to assess response rates in patients selected for S15 positivity. As of
December 2020, NC318 continued to be well tolerated in the Phase 2 portion of the trial, with primarily mild or moderate
TRAEs. The only observed severe or higher grade TRAE in the Phase 2 portion was a grade 3-4 TRAE infusion reaction in
one  patient.  While  we  no  longer  plan  to  initiate  a  study  of  NC318  in  combination  with  chemotherapy  at  this  time,  we
believe that scientific evidence supports a combination of NC318 with anti-PD-1 therapy. In the second quarter of 2021,
Yale plans to initiate a Phase 2 IIT of NC318 in combination with pembrolizumab, an anti-PD-1, in NSCLC patients. We
have exclusive worldwide rights to NC318.

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

S15  molecules  on  M2  macrophages,  as  well  as  on  tumors  themselves,  appear  to  interact  with  unidentified
receptors on T cells and inhibit T cell proliferation and functions, leading to decreased anti-tumor immune response. It also
appears  that  S15  interacts  with  myeloid  cells  to  promote  their  survival  and  differentiation  so  that  they  contribute  to  the
overall immunosuppressive tumor environment through production of cytokines, such as IL-6, IL-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.

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.  Patients  receive  NC318  on  day  one  of  each  cycle.  We  initiated  the  trial  with  14-day
cycles;  however,  over  the  course  of  the  trial  we  expect  to  continue  to  evaluate  alternate  doses  and  dose  administration
schedules  depending  on  pharmacokinetics,  pharmacodynamics,  biomarker  data,  safety  results  and  feedback  from
investigators. The trial is being conducted in two phases.

13

Table of Contents

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 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
will be 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 head and neck squamous cell carcinoma patient, which
supported advancing that indication into the second stage of the Simon 2-stage trial. In addition, at the time, 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. Of the evaluable biopsies collected, 13% of the patients enrolled had S15-positive
tumors.  These  biopsies  showed  that  the  selection  criterion  of  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 are modifying the ongoing Phase 2
portion of the trial for S15 selection and expect to begin pre-selecting patients for enrollment based on S15 expression in
the  second  quarter  of  2021  after  the  assay  we  have  selected  for  evaluating  S15  expression  has  been  validated  under  the
Clinical Laboratory Improvements Amendment, or CLIA. We anticipate the assay and the selection of S15 positive patients
will allow us to assess response rates in patients selected for S15 positivity. As of December 2020, NC318 continued to be
well  tolerated  in  the  Phase  2  portion  of  the  trial,  with  primarily  mild  or  moderate  TRAEs.  The  only  observed  severe  or
higher grade TRAE in the Phase 2 portion was a grade 3-4 TRAE infusion reaction in one patient.

Phase 2 Combination Clinical Trial

We believe scientific evidence supports a combination with anti-PD-1 therapy. In the second quarter of 2021, Yale

plans to initiate a Phase 2 IIT of NC318 in combination with pembrolizumab, an anti-PD-1, in patients with NSCLC.

14

Table of Contents

We understand that the trial is designed with both monotherapy arms to evaluate safety and responses to NC318 alone, and
combination arms to evaluate the safety of the combination with pembrolizumab and responses to the combination. At this
time, we no longer plan to initiate a study of NC318 in combination with chemotherapy.

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. The FDA accepted our IND in the first quarter of 2020 and we initiated the Phase 1 portion of a Phase
1/2  clinical  trial  in  patients  with  advanced  or  metastatic  solid  tumors  in  June  2020  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,  and  to  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.  We  expect  to  announce  data  from  the  Phase  1  portion  of  this  trial  in  the  second  half  of  2021.  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.

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

Preclinical Data

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

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

16

Table of Contents

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

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

NC410 Showed Anti-Tumor Activity

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

NC410 Increased T Cells Both Systemically and Locally

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

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 are conducting expansive screening efforts on tumor samples from different solid tumor types
to  identify  tumors  that  express  LAIR-1  on  the  surface  of  either  cancer  cells  or  infiltrating  immune  cells  to  guide  our
ultimate selection of patients for the Phase 2 portion of the Phase 1/2 clinical trial.

The FDA accepted our IND in the first quarter of 2020 and we initiated the Phase 1 portion of a Phase 1/2 clinical trial in
patients with advanced or metastatic solid tumors in June 2020 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, and
to 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. We expect to

19

Table of Contents

announce data from the Phase 1 portion of this trial in the second half of 2021. We have exclusive worldwide rights to
NC410.

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. We submitted an IND to the
FDA for NC762 in the first quarter of 2021, and we intend to initiate a Phase 1/2 clinical trial of NC762 in patients with
lung cancer, HER2+ breast cancer, and ovarian cancer, and potentially other tumor types in the second quarter of 2021. We
anticipate initial Phase 1 data in mid-2022. In connection with our development work for NC762, we have developed an
immunohistochemistry, or IHC, assay to test tumors for B7-H4 positivity and have performed screening of multiple tumor
types. We have validated the assay for use in clinical trials, and we intend to use it in the Phase 1/2 clinical trial to select
patients  for  treatment  through  patient  biopsies.  In  addition  to  the planned  clinical  trial,  we  plan  to  continue  pre-clinical
work  including  to  identify  tumor  indications  most  likely  to  respond  to  NC762.  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  lab,  and  PD-L2.  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 pre-clinical 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 (see "-Preclinical Data" below), 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 tumor microenvironment, meaning that it should not require the use of a separate toxic payload linked
to  the  antibody  as  part  of  treatment.  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  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  cells  such  as  tumor  cells.  Extensive  in  vivo  modeling  data  using  human
melanoma in mouse models expressing B7-H4 indicates 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

20

Table of Contents

several types of white blood cells including NK cells), and that the primary mechanism by which NC762 inhibits tumor
growth is therefore ADCC-independent.

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.

Preclinical Data

To demonstrate that NC762's mechanism of action is independent of ADCC, we inoculated immunodeficient mice
with  human  melanoma  cells  expressing  B7-H4  and  treated  the  mice  with  either  NC762  or  a  version  of  NC762,  called
NC762.FES,  that  we  modified  to  significantly  reduce  its  ability  to  bind  to  immune  cell  receptors,  which  essentially
eliminated  any  ADCC  activity  that  may  be  caused  by  NC762.  Mice  treated  with  both  versions  of  NC762  experienced
significantly reduced tumor growth as compared to the control group (left panel). The data therefore indicates that NC762
mediated  inhibitory  activity  on  tumor  growth  in vivo  independent  of  ADCC  activity.  The  data  also  shows  that  NC762's
anti-tumor  effect  may  be  enhanced  in  the  presence  of  NK  cells  (middle  panel),  but  that  T-cells  are  not  required  (right
panel).

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

21

Table of Contents

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.

We submitted an IND to the FDA for NC762 in the first quarter of 2021, and we intend to initiate a Phase 1/2
clinical trial of NC762 in patients with lung cancer, HER2+ breast cancer, and ovarian cancer, and potentially other tumor
types  in  the  second  quarter  of  2021.  The  Phase  1  dose-escalation  portion  of  this  open-label  trial  is  being  designed  to
evaluate  the  safety  and  tolerability  of  NC762,  and  to  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.

Our Research Programs

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

immunomodulatory molecules.

Our FIND-IO Discovery Engine

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

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

22

Table of Contents

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

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

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

23

Table of Contents

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

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

Our Collaboration Agreements

Agreements with Yale University

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 amended the Yale Agreement effective January 2020. 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  the
SRA, with Yale, pursuant to which we have agreed to provide an aggregate of up to $15 million to fund a research program
aimed  at  discovering  new  targets  for  immunomedicines.  The  research  program  is  under  the  direction  and  supervision  of
Dr.  Chen.  Pursuant  to  the  SRA,  we  have  the  option  to  add  any  patents  invented  pursuant  to  the  research  program  as  a
licensed  patent  under  the  Yale  Agreement  and  the  right  to  obtain  a  royalty-bearing,  exclusive,  worldwide  license  to  any
such patents. If we do not exercise our option within the exercise period, Yale is permitted to license any such patents to
any third party. The SRA has been extended for one year and will expire on December 31, 2021. We have the option of
further extending the term upon mutual agreement with Yale. We can terminate the SRA at any time upon 90 days’ written
notice to Yale. Yale can terminate for an uncured breach or with 90 days’ written notice for cause.

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
had an initial production capacity of 1,000 liters, but that capacity was expanded in 2020 to 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, and NC762. 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, 2020, our intellectual property portfolio
includes,  on  a  worldwide  basis,  20  pending  foreign  patent  applications  relating  to  NC318,  NC410,  and  NC762,  two
pending  U.S.  patent  application  relating  to  NC318,  one  pending  U.S.  patent  application  relating  to  NC410,  and  two
pending  U.S.  patent  applications  relating  to  NC762,  and  additional  pending  patent  applications  for  other  discovery  and
research programs. Patents resulting from our patent applications for NC318 and NC410, if issued, are expected to expire
beginning

25

Table of Contents

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.

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

26

include the suspension or termination of clinical trials by the FDA, the FDA’s refusal to approve pending applications or
supplemental  applications,  withdrawal  of  an  approval,  Warning  Letters  or  Untitled  Letters,  product  recalls,  product
seizures,  total  or  partial  suspension  of  production  or  distribution,  import  detention,  injunctions,  fines,  refusals  of
government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by the
FDA, the Department of Justice, or the DOJ, or other governmental entities.

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

the following:

● 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
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.

28

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  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 and when the
deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA, the FDA will issue an approval
letter. In issuing the CRL, the FDA may recommend actions that the applicant might take to place the BLA in condition for
approval, including requests for additional data, information or clarification. The FDA may delay or refuse approval of a
BLA  if  applicable  regulatory  criteria  are  not  satisfied,  and  may  require  additional  testing  or  information  and/or  require
post-marketing  studies  and  clinical  trials.  Even  with  submission  of  this  additional  information,  the  FDA  ultimately  may
decide that the application does not satisfy the regulatory criteria for approval.

30

Table of Contents

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. There also are continuing user fee requirements, under which FDA assesses an annual
program fee for each product identified in an approved BLA. Biologic manufacturers and their third-party contractors are
required  to  register  their  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, postmarketing 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.

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;

31

Table of Contents

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

Patent Term Restoration and Marketing Exclusivity

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

For  patents  that  might  expire  during  the  application  phase,  the  patent  owner  may  request  an  interim  patent
extension. An interim patent extension increases the patent term by one year and may be renewed up to four times. For
each interim patent extension granted, the post-approval patent extension is reduced by one year. The director of the

32

Table of Contents

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

33

Table of Contents

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 postmarket oversight of laboratory operational processes. CMS’s oversight through
the CLIA program is designed to confirm that a lab assesses analytical validity, but does not confirm whether it had results
from an analytical validity assessment that were sufficient to support the claimed intended use of the test.

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

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

34

Table of Contents

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.  Third-party  payors  establish  the  coverage  and  reimbursement
policies for pharmaceutical products, and the marketability of any products for which we may receive regulatory approval
for  commercial  sale  depends  on  those  payors’  coverage  policies  and  reimbursement  rates.  Third-party  payors  may  limit
coverage  to  specific  products  on  an  approved  list,  or  formulary,  which  might  not  include  one  or  more  of  our  product
candidates.  Third-party  payors,  together  with  regulators  and  others,  are  increasingly  challenging  the  prices  charged  for
pharmaceutical products and health services, in addition to their cost-effectiveness, safety and efficacy.

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

Moreover, obtaining coverage and adequate reimbursement is a time-consuming and costly process. We may be
required to provide scientific and clinical support for the use of any product to each third-party payor separately with no
assurance  that  approval  will  be  obtained,  and  we  may  need  to  conduct  expensive  pharmacoeconomic  studies  in  order  to
demonstrate  the  cost-effectiveness  of  our  products.  We  cannot  be  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.  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,  there  are  no  safe
harbors for many common practices, such as educational and research grants or patient or product assistance
programs;

● 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

35

Table of Contents

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. 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. 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.  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  and  its  implementing  regulations,  which  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.
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 Act and the California Consumer Privacy Act, or CCPA. Compliance with these
laws – which differ in significant ways and may not have the same effect – is constantly evolving and can be
difficult  and  time  consuming.  The  CCPA,  which  took  effect  on  January  1,  2020,  establishes  certain
requirements for data use and sharing transparency and creates new data privacy rights for consumers, and
other states could enact similar laws. Federal regulators, state attorneys general and plaintiffs’ attorneys have
been  and  will  likely  continue  to  be  active  in  this  space.  Similarly,  numerous  legislative  proposals  in  the
European Union, the United States, at both the federal and state level, and other jurisdictions could impose
new  obligations  or  limitations  that  affect  our  business.  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,  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

36

Table of Contents

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 by 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.

The  ACA  and  certain  of  its  provisions  have  been  subject  to  judicial  challenges  as  well  as  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

37

Table of Contents

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. Additional legislative or regulatory changes related to the ACA remain
possible.

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 February 10,
2021, the Biden Administration withdrew the federal government’s support for overturning the ACA. The case is expected
to  be  decided  by  mid-2021.  It  is  unclear  how  the  ultimate  decision  in  this  case,  or  other  efforts  to  repeal,  replace  or
invalidate the ACA or its implementing regulations, or portions thereof, will impact the ACA and its implementation.

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, 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,  but  the  final  rule  is  currently  subject  to  a  nationwide  preliminary  injunction,  and  it  remains  to  be  seen  whether
orders  such  as  these  and  resulting  regulations  will  remain  in  force  during  the  Biden  Administration  Policymakers  have
indicated that they will continue to seek legislative and administrative measures to control drug costs. Individual states in
the United States have also increasingly passed legislation and implemented regulations designed to control pharmaceutical
and  biological  product  pricing,  including  price  or  patient  reimbursement  limitations,  discounts,  restrictions  on  certain
product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to  encourage
importation from other countries and bulk purchasing. In addition, regional healthcare authorities and individual hospitals
are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included
in their prescription drug and other healthcare programs.

Moreover, 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, 2020, we had 90 full-time employees.

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

38

Table of Contents

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.

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
and Results of Operations,” before deciding whether to invest in our common stock. If any of the events described below
actually occurs, our business, results of operations, financial conditions, cash flows or prospects could be harmed. If that
were to happen, the trading price of our common stock could decline, and you could lose all or part of your investment.
Additional  risks  and  uncertainties  not  presently  known  to  us  or  that  we  currently  deem  immaterial  may  also  impair  our
business operations.

Risks Related to Our Financial Position and Need for Additional Capital

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

We are a clinical-stage biopharmaceutical company with a limited operating history. Since our founding in 2015,
we have incurred significant net losses. Our net losses were $36.6 million and $33.7 million for the years ended December
31,  2020  and  2019,  respectively.  As  of  December  31,  2020,  we  had  an  accumulated  deficit  of  $117.6  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;

39

Table of Contents

● 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.

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 and NC410 and our planned Phase 1/2 clinical for 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;

40

Table of Contents

● 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, or NC762, we will require significant additional
amounts of cash in order to launch and commercialize such product candidates. In addition, other unanticipated costs may
arise.  Because  the  designs  and  outcomes  of  our  planned  and  anticipated  clinical  trials  are  highly  uncertain,  we  cannot
reasonably  estimate  the  actual  amounts  necessary  to  successfully  complete  the  development  of  and  commercialize  any
product candidate we develop.

Our future capital requirements depend on many factors, including:

● the scope, progress, timing, results and costs of researching and developing NC318, NC410, NC762 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, and any

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

● the costs of manufacturing NC318, NC410, NC762 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 and any future product candidates we develop, whether alone or with a collaborator, if any of
these product candidates are approved for sale;

● the success of the SRA with Yale;

● 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,  2020,  we  had  $283.4  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 second half of 2023.
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

Recently announced interim results regarding our NC318 monotherapy Phase 1/2 clinical trial may adversely impact
our product development efforts.

In July 2020, we announced that based on the current enrollment criteria and clinical response data, we did not
plan at that time to advance the NSCLC and ovarian cancer cohorts of our NC318 Phase 1/2 monotherapy clinical trial into
the stage 2 portion of the Simon 2-stage trial. In December 2020, we announced that the initial selection criterion did not
result in enough S15-positive patients for us to effectively evaluate the activity of NC318 in S15-positive tumors. We are
modifying the Phase 2 portion of the trial for S15 selection and expect to begin pre-selecting patients for enrollment based
on  S15  expression  in  the  second  quarter  of  2021,  which  we  anticipate  will  allow  us  to  assess  response  rates  in  patients
selected for S15 positivity. The developments in this trial could increase the costs and lengthen the timeline for this trial,
adversely  impact  our  ability  to  enroll  patients  and  impair  our  ability  to  gain  regulatory  approval  for  and  commercialize
NC318.  We  could  also  make  decisions  about  pursuing  particular  tumor  types  based  on  incomplete  facts,  resulting  in
decisions  to  either  pursue  indications  that  we  should  not  pursue,  or  to  not  pursue  indications  that  we  should  pursue.  In
addition,  our  former  chief  medical  officer  resigned  effective  August  4,  2020,  and  a  new  chief  medical  officer  was
appointed  effective  January  14,  2021.  This  transition  could  also  delay  or  otherwise  adversely  impact  our  development
efforts for NC318 and our other product candidates. Any of these developments could damage our reputation or investor
confidence in our company, disrupt our broader research and development, impact our ability to raise capital, or hinder our
ability  to  execute  our  strategic  plans,  which  could  have  a  material  adverse  effect  on  our  business,  financial  condition,
operating results and prospects.

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

42

Table of Contents

trial  for  S15  selection.  And,  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 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  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  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. While we are considered an essential business under applicable regulations and continue to operate, the
impacts of COVID-19 initially placed significant strain on our clinical trial sites, have raised concerns around monitoring
patient safety, and caused enrollment to slow in the Phase 2 portion of the ongoing Phase 1/2 monotherapy clinical trial of
our  lead  product  candidate,  NC318.  Spikes  of  COVID-19  infection  rates,  especially  in  the  United  States,  could  also
negatively affect enrollment. 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. Specifically, initial data from the Phase
2 portion of our ongoing Phase 1/2 clinical trial of NC318 were temporarily delayed, and the initial delay of our Phase 2
clinical trial to evaluate NC318 in combination with standard of care chemotherapies was due to COVID-19. In addition,
we delayed until July 2020 initiation of the Phase 1 portion of our Phase 1/2 clinical trial of NC410 despite being prepared
to  begin  the  trial  in  March  2020.  The  impacts  of  the  COVID-19  pandemic  could  adversely  affect  our  clinical  trials  and
operations in other ways as well. For example, further 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 or losing productivity, 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 this
“Risk Factors” section, 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.  We  cannot  predict  the  scope  and  severity  of  any
further disruptions as a result of COVID-19 or their impacts on us, but 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 continue to 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 submitted the IND for
our first clinical trial for our third product candidate, NC762, in the first quarter of 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;

● 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;

44

Table of Contents

● 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 postmarketing 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 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;

● 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;

45

Table of Contents

● 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  postmarketing
requirements,  or  may  approve  a  product  candidate  with  a  label  that  does  not  include  the  labeling  claims  we  believe  are
necessary or desirable for the successful commercialization of such product candidates.

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. Although we initiated
Phase 1/2 clinical trials of NC318 and NC410 in October 2018 and June 2020, respectively, and submitted the IND for a
Phase 1/2 clinical trial of NC762 in the first quarter of 2021, 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 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 are modifying the Phase 2 portion of our ongoing Phase 1/2 clinical trial of NC318 for
S15 selection and expect to begin pre-selecting patients for enrollment based on S15 expression in the second quarter of
2021,  which  we  anticipate  will  allow  us  to  assess  response  rates  in  patients  selected  for  S15  positivity  after  the  initial
selection  criterion  did  not  result  in  enough  S15-positive  patients.  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;

● 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;

46

Table of Contents

● 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
coronavirus.

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 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

47

Table of Contents

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  coronavirus,  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:

● 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 and NC410 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 and NC410 and what is expected
for our planned Phase 1/2 clinical trial of NC762, can be disproportionately influenced by the impact the treatment had on
a  few  individuals,  which  limits  the  ability  to  generalize  the  results  across  a  broader  community,  thus  making  the  study
results  less  reliable  than  studies  with  a  larger  number  of  subjects  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

49

Table of Contents

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
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.

50

Table of Contents

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  or  any  other  product  candidate  is  safe  in  humans,  and  we
cannot  predict  if  ongoing  or  future  clinical  trials  will  do  so.  If  any  of  our  current  or  future  product  candidates  fail  to
demonstrate safety and efficacy in clinical trials or do not gain marketing approval, we will not be able to generate revenue
and our business will be harmed.

In  addition,  we  intend  to  pursue  NC318  in  part  in  combination  with  other  therapies  and  may  develop  NC410,
NC762 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.  See  also  “—Risks  Related  to  the
Discovery and Development of Our Product Candidates—We intend to develop NC318 in part in combination with other
therapies  and  may  develop  NC410,  NC762,  and  future  product  candidates  in  combination  with  other  therapies,  which
exposes us to additional regulatory risks.”

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.

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 we or our collaborators encounter difficulties enrolling patients in our clinical trials, as we have in the Phase 2
portion of our ongoing Phase 1/2 clinical trial of NC318, 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 temporary slowdown of enrollment in the Phase 2 portion of our ongoing Phase 1/2 clinical
trial of NC318 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 coronavirus.

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.

52

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, and NC762. 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,
and  NC762  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.

53

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.

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 tumor microenvironment is novel
and  unproven.  In  addition,  adverse  events  in  clinical  trials  testing  our  product  candidates  or  in  clinical  trials  of  others
developing  similar  product  candidates  and  the  resulting  publicity,  as  well  as  any  other  adverse  events  in  the  field  of
immuno-oncology  that  may  occur  in  the  future,  could  result  in  a  decrease  in  demand  for  our  current  or  future  product
candidates. If public perception is influenced by claims that the use of cancer immunotherapies is unsafe, whether related
to  our  immunomedicines  or  our  competitors’  products,  our  products  may  not  be  accepted  by  the  general  public  or  the
medical  community.  Future  adverse  events  in  immuno-oncology  or  the  biopharmaceutical  industry  could  also  result  in
greater governmental regulation, stricter labeling requirements and potential regulatory delays in the testing or approvals of
our products.

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

● 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  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 intend to develop NC318 in part in combination with other therapies and may develop NC410, NC762, and future
product candidates in combination with other therapies, which exposes us to additional regulatory risks.

We intend to develop NC318 in part in combination with other therapies and may develop NC410, NC762 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

56

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 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  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 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 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 and personal information, and data to comply with cGMP and data integrity requirements.
It is critical that we do so in a secure manner to maintain data security and data integrity of such information. We have
established  physical,  electronic  and  organizational  measures  to  safeguard  and  secure  our  systems  to  prevent  a  data
compromise. We have also outsourced elements of our information technology infrastructure, and as a result a number of
third-party  vendors  may  or  could  have  access  to  our  confidential  information.  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. The
risk  of  a  security  breach  or  disruption  or  data  loss,  including  by  computer  hackers,  foreign  governments  and  cyber
terrorists,  has  generally  increased  as  the  number,  intensity  and  sophistication  of  attempted  attacks  and  intrusions  from
around  the  world  have  increased.  In  addition,  the  prevalent  use  of  mobile  devices  that  access  confidential  information
increases the risk of data security breaches, which could lead to the loss of confidential information or other intellectual
property. The costs to us to mitigate network security problems, bugs, viruses, worms, malicious software programs and
security vulnerabilities could be significant, and while we have implemented security measures to protect our data security
and information technology systems, our efforts to address these problems may not be successful, and these problems could
result in unexpected interruptions, delays, cessation of service and other harm to our business and our competitive position.
If  such  an  event  were  to  occur  and  cause  interruptions  in  our  operations,  it  could  result  in  a  material  disruption  of  our
product development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical
trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce
the data. Likewise, we rely on third parties to conduct clinical trials, and similar events relating to their computer systems
could also have a material adverse effect on our business. Moreover, if a computer security breach affects our systems or
results in the unauthorized release of personally identifiable information, our reputation could be materially damaged. In
addition,  such  a  breach  may  require  notification  to  governmental  agencies,  the  media  or  individuals  pursuant  to  various
federal  and  state  privacy  and  security  laws,  if  applicable,  including  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.

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

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

59

Table of Contents

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

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

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare
costs. In particular, there have been and continue to be a number of initiatives at the U.S. federal and state levels that seek
to  reduce  healthcare  costs  and  improve  the  quality  of  healthcare.  For  example,  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  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. Additional legislative or regulatory changes related to the ACA remain possible.

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. 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 February 10, 2021, the Biden
Administration withdrew the federal government’s support for overturning the ACA. The case is expected to be decided by
mid-2021. It is unclear how the ultimate decision in this case, or other efforts to repeal, replace, or invalidate the ACA or
its implementing regulations, or portions thereof, will impact the ACA and implementation.

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 through 2030, with the exception of a temporary suspension from May 1, 2020 through December 31, 2020,
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.

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

61

Table of Contents

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, but the final rule is
currently  subject  to  a  nationwide  preliminary  injunction,  and  it  remains  to  be  seen  whether  orders  such  as  these  and
resulting  regulations  will  remain  in  force  during  the  Biden  Administration.  Policymakers  have  indicated  that  they  will
continue  to  seek  legislative  and  administrative  measures  to  control  drug  costs.  We  expect  that  additional  U.S.  federal
healthcare  reform  measures  will  be  adopted  in  the  future,  any  of  which  could  limit  the  extent  to  which  the  U.S.  federal
government  covers  particular  healthcare  products  and  services  and  could  limit  the  amounts  that  the  U.S.  federal
government will pay for healthcare products and services. This could result in reduced demand for our product candidates
or additional pricing pressures.

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

Additionally,  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

62

Table of Contents

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, and NC762 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, or NC762. 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 and NC410 and our planned Phase 1/2 clinical trial of 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

64

Table of Contents

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 and any future
product candidates may be manufactured at a CMO or CMOs.

The  facilities  used  by  our  CMOs  to  manufacture  our  product  candidates  are  subject  to  various  regulatory
requirements  and  may  be  subject  to  the  inspection  of  the  FDA  or  other  regulatory  authorities.  We  do  not  control  the
manufacturing  process  at  our  CMOs,  and  are  completely  dependent  on  them  for  compliance  with  current  regulatory
requirements.  If  we  or  our  CMOs  cannot  successfully  manufacture  material  that  conforms  to  our  specifications  and  the
strict regulatory requirements of the FDA or comparable regulatory authorities in foreign jurisdictions, we may not be able
to rely on their manufacturing facilities for 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

65

Table of Contents

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
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

66

Table of Contents

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

67

Table of Contents

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

68

Table of Contents

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.

69

Table of Contents

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

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

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

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

70

Table of Contents

will  not  be  assigned  to  third  parties.  In  the  event  of  unauthorized  use  or  disclosure  of  our  trade  secrets  or  proprietary
information, these agreements, even if obtained, may not provide meaningful protection, particularly for our trade secrets
or other confidential information. To the extent that our employees, consultants or contractors use technology or know-how
owned by third parties in their work for us, disputes may arise between us and those third parties as to the rights in related
inventions. To the extent that an individual who is not obligated to assign rights in intellectual property to us is rightfully an
inventor of intellectual property, we may need to obtain an assignment or a license to that intellectual property from that
individual,  or  a  third  party  or  from  that  individual’s  assignee.  Such  assignment  or  license  may  not  be  available  on
commercially reasonable terms or at all. We also seek to preserve the integrity and confidentiality of our trade secrets by
other  means,  including  maintaining  physical  security  of  our  premises  and  physical  and  electronic  security  of  our
information technology systems. However, these security measures may be breached, and we may be forced to bring claims
against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our
intellectual property.

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

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

Many  of  our  employees,  consultants  or  advisors  are  currently,  or  were  previously,  employed  at  universities  or
other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to
ensure that our employees, consultants and advisors do not use the proprietary information or know-how of others in their
work  for  us,  we  may  be  subject  to  claims  that  these  individuals,  or  we,  have  used  or  disclosed  intellectual  property,
including trade secrets or other proprietary information, of any such individual’s current or former employer, or that patents
and applications we have filed to protect inventions of these employees, even those related to one or more of our product
candidates, are rightfully owned by their former or current employer. Litigation may be necessary to defend against these
claims. 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.

71

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;

● 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 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 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

72

Table of Contents

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 coronavirus, do not
meet expected deadlines, terminate their agreements with us or need to be replaced, or if the quality or accuracy of the data
they obtain is compromised due to their failure to adhere to our protocols or to GLP and cGCP, or for any other reason, we
may need to enter into new arrangements with alternative third parties. This could be difficult, costly or impossible, and
our preclinical studies or clinical trials may need to be extended, delayed, terminated or repeated. As a result, we may not
be able to obtain regulatory approval in a timely fashion, or at all, for the applicable product candidate, our financial results
and  the  commercial  prospects  for  our  product  candidates  would  be  harmed,  our  costs  could  increase  and  our  ability  to
generate revenues could be delayed.

We may depend on 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.

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

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

Our  collaborations  pose,  and  potential  future  collaborations  involving  our  product  candidates  may  pose,  the

following risks to us:

● 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;

73

Table of Contents

● 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.

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

74

Table of Contents

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  our  President  and  Chief  Executive  Officer  Michael  Richman,  our  scientific  founder  Dr.  Lieping  Chen  who
serves as a consultant to us or one or more of our other executive officers could impede the achievement of our research,
development and commercialization objectives. For example, our former chief medical officer resigned effective August 4,
2020, and a new chief medical officer was appointed effective January 11, 2021. This transition could delay or otherwise
adversely impact our development efforts for NC318 and our other product candidates.

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

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

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

The biotechnology industry is intensely competitive and subject to rapid and significant technological change. Our
current or future product candidates may face competition from major pharmaceutical companies, specialty pharmaceutical
companies,  universities  and  other  research  institutions  and  from  products  and  therapies  that  currently  exist  or  are  being
developed,  some  of  which  products  and  therapies  we  may  not  currently  know  about.  Many  of  our  competitors  have
significantly greater financial, manufacturing, marketing, product development, technical and human resources than we do.
Large  pharmaceutical  companies,  in  particular,  have  extensive  experience  in  clinical  testing,  obtaining  marketing
approvals, recruiting patients and manufacturing pharmaceutical products, and they may also have products that have been
approved  or  are  in  late  stages  of  development,  and  collaborative  arrangements  in  our  target  markets  with  leading
companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery
and development of novel compounds or to in-license novel compounds that could make the product candidates that we
develop  obsolete.  Mergers  and  acquisitions  in  the  pharmaceutical  and  biotechnology  industries  may  result  in  even  more
resources  being  concentrated  among  a  smaller  number  of  our  competitors.  As  a  result  of  all  of  these  factors,  our
competitors  may  succeed  in  obtaining  patent  protection  and/or  FDA  or  other  regulatory  approval  or  discovering,
developing and commercializing products in our field before we do, which could result in our competitors establishing a
strong market position before we are able to enter the market.

Our competitors may obtain FDA or other regulatory approval of their product candidates more rapidly than we
may or may obtain patent protection or other intellectual property rights that limit our ability to develop or commercialize
our product candidates or platform technologies. Our competitors may also develop drugs or discovery platforms that are

75

Table of Contents

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 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

76

Table of Contents

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 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 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 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

● 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;

77

Table of Contents

● 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.

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, 2020, we had federal
and state net operating loss carryforwards of $103.2 million and $105 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.

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;

79

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 negative evaluations of our
stock, the price of our stock could decline.

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

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. Shares registered under these
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.

In addition, the holders of certain shares of our common stock outstanding as of December 31, 2020 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.

80

Table of Contents

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 Securities Exchange Act of
1934, as amended, 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  intend  to  move  to  dismiss  the
consolidated amended complaint and discovery is stayed pending resolution of that motion. We intend to vigorously defend
the  action.  However,  whether  or  not  the  claims  are  successful,  this  type  of  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
insurance; however, if any costs or expenses associated with the Ye Zhou action or any other litigation exceed our insurance
coverage, we may be forced to bear some or all of these 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

81

Table of Contents

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.

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

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

82

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.

Item 1B. Unresolved Staff Comments

Not Applicable.

Item 2. Properties

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

PART II

Item  5.  Market  for  Registrant’s  Common  Equity,  Related  Stockholder  Matter  and  Issuer  Purchases  of
Equity Securities

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 3, 2021 we had 27,599,949 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, 2020, $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.

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.

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. While we are considered an essential business under applicable regulations and continue to operate, the
impacts of COVID-19 initially placed significant strain on our clinical trial sites, have raised concerns around monitoring
patient safety, and caused enrollment to slow in the Phase 2 portion of the ongoing Phase 1/2 monotherapy clinical trial of
our lead product candidate, NC318. 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 COVID-19 pandemic
and  its  impacts  continue  to  evolve.  We  cannot  predict  the  scope  and  severity  of  any  further  disruptions  as  a  result  of
COVID-19  or  their  impacts  on  us,  but  business  disruptions  for  us  or  any  of  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 continue
to  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,  the  extent  and  effectiveness  of
government restrictions and other actions, including relief measures, implemented to address the impact of the pandemic,
and resulting economic impacts. We are unable to determine the extent of the impact of the pandemic on our operations and
financial  condition  going  forward.  These  developments  are  highly  uncertain  and  unpredictable,  and  may  materially
adversely affect our financial position and results of operations.

Our  lead  product  candidate  NC318  is  a  first-in-class  immunomedicine  against  a  novel  immunomodulatory
receptor  called  Siglec-15,  or  S15.  In  October  2018,  we  initiated  a  Phase  1/2  clinical  trial  of  NC318  in  patients  with
advanced  or  metastatic  solid  tumors.  We  completed  enrollment  of  the  Phase  1  portion  of  this  trial  in  August  2019  and
preliminary data from the Phase 1 portion were presented at the Society for Immunotherapy of Cancer annual meeting in
November 2019 and updated data were announced in December 2020.

We began enrolling patients in the Phase 2 portion of the Phase 1/2 clinical trial of NC318 trial 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. In July 2020, we reported a confirmed partial response in a head and
neck  squamous  cell  carcinoma  patient.  In  addition,  at  the  time,  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. Of

85

Table of Contents

the  evaluable  biopsies  collected,  13%  of  the  patients  enrolled  had  S15-positive  tumors.  These  biopsies  showed  that  the
selection criterion did not result in enough S15-positive patients for us to effectively evaluate the activity of NC318 in S15-
positive  tumors.  We  are  modifying  the  Phase  2  portion  of  the  trial  for  S15  selection  and  expect  to  begin  pre-selecting
patients for enrollment based on S15 expression in the second quarter of 2021 in order to assess response rates in patients
selected for S15 positivity. In addition, we believe that scientific evidence supports a combination of NC318 with anti-PD-
1 therapy, and we plan to study that combination in NSCLC patients.

Our  second  product  candidate,  NC410,  is  a  novel  immunomedicine  designed  to  block  immune  suppression
mediated  by  an  immune  modulator  called  Leukocyte-Associated  Immunoglobulin-like  Receptor  1.  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. We expect to announce data from the Phase 1 portion of this
trial in the second half of 2021.

Our  third  product  candidate,  NC762,  is  an  immunomedicine  targeting  an  immunomodulatory  molecule  called
human B7 homolog 4 protein, or B7-H4. We submitted our investigational new drug application, or IND, for NC762, to the
FDA, in the first quarter of 2021, and we intend to initiate a Phase 1/2 clinical trial of NC762 in patients with lung cancer,
HER2+  breast  cancer,  ovarian  cancer  or  potentially  other  tumor  types  in  the  second  quarter  of  2021.  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.

Financial Overview

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

We  have  not  generated  any  revenue  from  product  sales  and  only  limited  revenue  from  other  sources  and,  as  a
result,  we  have  never  been  profitable  and  have  incurred  net  losses  since  the  commencement  of  our  operations.  Our  net
losses  for  the  years  ended  December  31,  2020  and  2019  were  $36.6  million  and  $33.7  million,  respectively.  As  of
December 31, 2020, we had an accumulated deficit of $117.6 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,
private placements our preferred stock and upfront fees received under our former research collaboration and development
agreement  with  Eli  Lilly  and  Company,  or  Lilly.  From  our  inception  through  December  31,  2020,  we  received  gross
proceeds  of  $164.4  million  through  private  placements  of  preferred  stock  and  an  upfront  payment  of  $25.0  million  in
connection with our agreement with Lilly, or the Lilly Agreement.

In 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.

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 $76.9 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.

86

Table of Contents

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, 2020, we had cash, cash equivalents and marketable securities, excluding restricted cash, of
$283.4 million. We believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our
planned  operations  into  the  second  half  of  2023.  We  have  based  this  estimate  on  assumptions  that  may  prove  to  be
incorrect, and we could use our available capital resources sooner than we currently expect.

We  expect  to  incur  substantial  expenditures  in  the  foreseeable  future  as  we  advance  our  product  candidates
through clinical development, the regulatory approval process and, if approved, commercialization, and as we expand our
pipeline  through  research  and  development  activities  related  to  our  FIND-IO  platform  and  discovery  programs.
Specifically, in the near term, we expect to incur substantial expenses relating to our ongoing Phase 1/2 clinical trials for
NC318  and  NC410  and  our  planned  Phase  1/2  clinical  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 that we did not incur as a private company.

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

Components of Our Results of Operations

Revenue

We recognized revenue under the former Lilly Agreement of $22.4 million and $6.3 million for the years ended
December  31,  2020  and  2019,  respectively.  Lilly  terminated  the  Lilly  Agreement  effective  March  3,  2020,  or  the  Lilly
Termination Date, without cause and we recognized all of the remaining deferred revenue as of the Lilly Termination Date
in the statement of operations and comprehensive loss. Through December 31, 2020, 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  corporate  sponsored  research
agreement, or the SRA, and our license agreement with Yale University, or Yale;

● costs of outside consultants, including their fees, stock-based compensation and related travel expenses;

87

Table of Contents

● 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
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  and  NC762  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 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  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.

Other Income, Net

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

our term loan with a commercial bank, or the Term Loan.

Revenue from Former Research and Development Arrangement

Revenue was $22.4 million and $6.3 million for the years ended December 31, 2020 and 2019, respectively. The
2019  revenue  is  related  to  the  recognition  of  a  portion  of  the  upfront  consideration  under  the  Lilly  Agreement  and  the
premium  on  the  proceeds  from  Lilly’s  investment  in  shares  of  our  Series  B-3  Preferred  Stock.  The  2020  revenue
exclusively relates to the recognition of all of the remaining deferred revenue under the Lilly Agreement as of the Lilly
Termination Date. Effective with the termination of the Lilly Agreement, no further quarterly research and development
support payments are payable to us.

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, 2020 increased by $12.3 million to $46.6
million  compared  to  $34.2  million  for  the  year  ending  December  31,  2019.  The  increase  was  driven  primarily  by  $6.2
million  in  internal  research  and  development  expenses,  such  as  personnel-related  costs,  facilities  related  expenses,  and
depreciation. Another significant component of the increase in research and development expenses included $5.7 million in
external research and development expenses related to early-stage programs and discovery activities, such as lab supplies
and services, and payments pursuant to the SRA, and other sponsored research agreements.

General and Administrative Expenses

General and administrative expenses for the year ended December 31, 2020 increased by $7.4 million to $17.0
million as compared to $9.6 million for the year ending December 31, 2019. The increase was driven primarily by $4.6
million in personnel-related costs due to an increase in headcount. Other significant components of the increase in general
and administrative expenses included $1.6 million in professional fees related to legal, finance/audit services, public
relations, compensation, and investor relations support, and $1.0 million in insurance expenses.

Other Income, Net

Other income, net for the year ended December 31, 2020 increased by $0.9 million to $4.6 million compared to
$3.7 million for the year ended December 31, 2019. The increase was driven primarily by interest income earned on higher
cash and marketable securities balances.

Liquidity and Capital Resources

We  have  financed  our  operations  primarily  with  proceeds  from  public  offerings  of  our  common  stock,  private
placements of our preferred stock and upfront fees received under the Lilly Agreement. On May 13, 2019, we closed our
IPO in which we sold 5,750,000 shares of common stock, at a public offering price of $15.00 per share, for aggregate gross
proceeds of $86.3 million. The net offering proceeds to us were approximately $76.9 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. 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.

Table of Contents

As of December 31, 2020, we had cash, cash equivalents and marketable securities, excluding restricted cash, of
$283.4 million. We believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our
planned operations into the second half of 2023.

In  addition,  in  April  2016,  we  entered  into  a  term  loan  to  finance  laboratory  equipment  purchases.  In  January
2019, we amended the term loan to increase our borrowing capacity from $1.0 million to $5.0 million. As amended, the
term loan matures in January 2023. Our obligations under the term loan are secured by a security interest in our certificates
of deposit, money market accounts, cash, securities, investment property and deposit or investment accounts. The term loan
bears  interest  at  a  rate  equal  to  the  greater  of  (i)  the  prime  rate  less  1.0%  and  (ii)  4.25%  and  is  subject  to  mandatory
prepayment  upon  the  occurrence  of  specified  events,  including  failure  to  pay  the  term  loan  when  due,  uncured  breach,
bankruptcy  or  dissolution.  Under  the  term  loan,  we  made  interest-only  payments  through  January  2020  and  36  equal
monthly  payments  of  principal  plus  accrued  interest  thereafter  through  January  2023.  As  of  December  31,  2020,  our
outstanding borrowings under this term loan were $3.5 million.

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

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

● the  costs  of  manufacturing  NC318,  NC410  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 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;

● the success of the SRA with Yale;

● 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

91

Table of Contents

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.

Net  cash  used  in  operating  activities  was  $45.0  million  for  the  year  ended  December  31,  2020,  which  was
primarily due to our net loss of $36.6 million. Net cash used in operating activities was $35.6 million for the year ended
December  31,  2019,  which  was  primarily  due  to  our  net  loss  of  $33.7  million.  The  amount  of  cash  used  in  operating
activities in any period is influenced by the timing of cash payments for research-related expenses.

Cash Provided by/Used in Investing Activities

Cash provided by investing activities for the year ended December 31, 2020 was $43.5 million, which was primarily due to
the maturities of marketable securities that were not reinvested in marketable securities. Cash used in investing activities
for the year ended December 31, 2019 was $303.9 million, which was primarily due to the purchase of marketable
securities.

Cash Used in/Provided by Financing Activities

Cash  used  in  financing  activities  was  $1.4  million  for  the  year  ended  December  31,  2020,  which  consisted
primarily of repayment of a portion of the Term Loan. Cash provided by financing activities was $243.0 million for the
year ended December 31, 2019, which consisted primarily of net proceeds from the public offerings of our common stock.

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 currently $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

92

    
    
 
   
   
 
 
 
 
Table of Contents

subleasing under the 2016 Sublease. The base rent under the 2019 Lease is currently $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,  which  amount  remains  secured  by  our  certificates  of  deposit,
money market account, investment property and deposit or investment accounts. As amended, the Term Loan bears interest
at the greater of the prime rate less 1% and 4.25%. The effective interest rate was 4.25% and 4.40% for the years ended
December  31,  2020  and  2019,  respectively.  Under  the  Term  Loan,  we  were  required  to  make  monthly  interest-only
payments  through  January  2020  and  are  required  to  make  36  equal  monthly  payments  of  principal  plus  accrued  interest
thereafter  through  January  2023.  Interest  expense  under  the  Term  Loan  was  approximately  $183,000  and  $209,000  for
the years ended December 31, 2020 and 2019, respectively. The outstanding balance on the Term Loan totaled $3.5 million
and $5.0 million as of December 31, 2020 and 2019, 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 and the SRA 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.

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

93

Table of Contents

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 in the American Institute of Certified Public Accountants.

Accounting  and  Valuation  Guide,  Valuation  of  Privately-Held-Company  Equity  Securities  Issued  as
Compensation. Our common stock valuations were prepared using an option pricing method, or OPM, which used market
approaches to estimate our enterprise value. The OPM treats common stock and preferred stock as call options on the total
equity value of a company, with exercise prices based on the value thresholds at which the allocation among the various
holders of a company's securities changes. Under this method, the common stock has value only if the funds available for
distribution  to  stockholders  exceeded  the  value  of  the  preferred  stock  liquidation  preferences  at  the  time  of  the  liquidity
event,  such  as  a  strategic  sale  or  a  merger.  A  discount  for  lack  of  marketability  of  the  common  stock  is  then  applied  to
arrive at an indication of value for the common stock.

Since the closing of our IPO, 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.

94

Table of Contents

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, 2020
and 2019, the related statements of operations and comprehensive loss, preferred stock and stockholders’ equity (deficit)
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, 2020 and 2019, 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.

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  $76.9  million  after  deducting  underwriting  discounts  and  commissions  of  $6.0  million  and  offering
expenses of approximately $3.4 million.

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

Upon  the  closing  of  the  IPO,  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  approximately  $160.9  million  after  deducting  underwriting
discounts and commissions of approximately $10.3 million and offering expenses of approximately $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  2020,  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.

The Company expects that its operating losses and negative cash flows will continue for the foreseeable future. As
of the issuance date of the financial statements for the year ended December 31, 2020, the Company expects that its cash
and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements through at least
two years from the issuance date of the financial statements. The future viability of the Company beyond that date may
depend on its ability to raise additional capital to finance its operations.

102

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

In  March  2020,  the  World  Health  Organization  declared  the  novel  coronavirus  disease  2019  (“COVID-19”),
outbreak a pandemic. In order to mitigate the spread of COVID-19, governments have imposed unprecedented restrictions
on  business  operations,  travel  and  gatherings,  resulting  in  a  global  economic  downturn  and  other  adverse  economic  and
societal impacts. The COVID-19 pandemic has also overwhelmed or otherwise led to changes in the operations of many
healthcare facilities, including clinical trial sites.

The  impact  of  the  COVID-19  pandemic  on  the  Company’s  business  and  financial  performance  is  uncertain  and
depends on various factors, including the scope and duration of the pandemic, 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 initially placed significant strain
on the Company’s clinical trial sites, have raised concerns around monitoring patient safety, and caused enrollment to slow
in  the  Phase  2  portion  of  the  ongoing  Phase  1/2  monotherapy  clinical  trial  of  the  Company’s  lead  product  candidate,
NC318.  Any  rise  of  COVID-19  infection  rates,  especially  in  the  United  States,  could  continue  to  negatively  affect
enrollment going forward. The Company is unable to determine the extent of the impact of the pandemic on its operations
and  financial  condition  going  forward.  These  developments  are  highly  uncertain  and  unpredictable,  and  may  materially
adversely affect the Company’s financial position and results of operations. 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  makers  view  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
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

At December 31, 2020 and 2019, the Company had restricted cash of $3.5 million and $5.0, million, respectively.
The Company is required, as a condition of its Term Loan (Note 9), to maintain cash collateral on deposit in a segregated
money market bank account equal to the principal portion outstanding under the Term Loan on a quarterly basis. The bank
may restrict withdrawals or transfers by, or on behalf of, the Company. The required reserve totaled $3.5 million and $5.0
million as of December 31, 2020 and December 31, 2019, respectively. The 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:

$  36,284

$  39,130

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.

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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
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.

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,
2020 or 2019.

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’s preferred stock was classified outside of stockholders’ deficit as of December 31, 2018 and for
the  period  of  2019  during  which  it  was  outstanding  because  the  shares  carried  deemed  liquidation  rights  that  were  a
contingent redemption feature not solely within the control of the Company. This preferred stock was fully converted to
common  shares  during  2019.  The  Company  did  not  have  any  outstanding  preferred  stock  as  of  December  31,  2019  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.

106

    
 
 
 
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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
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.

NOTES TO FINANCIAL STATEMENTS

The  Company  expenses  the  fair  value  of  its  share-based  compensation  awards  on  a  straight-line  basis  over  the

requisite service period, which is generally the vesting period.

Income Taxes

The  Company  uses  the  asset  and  liability  method  of  accounting  for  income  taxes.  Deferred  tax  assets  and
liabilities  are  recognized  for  the  estimated  future  tax  consequences  attributable  to  temporary  differences  between  the
financial statement carrying amounts of existing assets and liabilities and their respective tax base. Deferred tax assets and
liabilities,  which  relate  primarily  to  the  carrying  amount  of  the  Company’s  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, 2020 and 2019.

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

108

Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

constrained and will be included in the transaction price only to the extent that it is probable that a significant reversal in
the amount of the cumulative revenue recognized will not occur in a future period.

The Company’s contracts may include development and regulatory milestone payments, which would be assessed
under  the  most  likely  amount  method  and  constrained  if  it  is  probable  that  a  significant  revenue  reversal  would  occur.
Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, will
not be considered probable of being achieved until those approvals are received. At the end of each reporting period, the
Company re-evaluates the probability of achievement of such development milestones and any related constraint, and if
necessary, adjusts its estimate of the overall transaction price. Any such adjustments would be recorded on a cumulative
catch-up basis, which would affect collaboration revenues in the period of adjustment.

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and
the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the
later of (i) when the related sales occur and (ii) when the performance obligation to which some or all of the royalty has
been allocated has been satisfied (or partially satisfied).

The  Company  allocates  the  transaction  price  based  on  the  estimated  stand-alone  selling  price  of  each  of  the
performance  obligations.  The  Company  must  develop  assumptions  that  require  judgment  to  determine  the  stand-alone
selling  price  for  each  performance  obligation  identified  in  the  contract.  The  Company  utilizes  key  assumptions  to
determine the stand-alone selling price for service obligations, which may include other comparable transactions, pricing
considered in negotiating the transaction and the estimated costs. Additionally, in determining the standalone selling price
for material rights, the Company may reference comparable transactions, clinical trial success probabilities and estimates
of option exercise likelihood. Variable consideration will be allocated specifically to one or more performance obligations
in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the
resulting amounts allocated are consistent with the amounts the Company would expect to receive for the satisfaction of
each performance obligation.

The consideration allocated to each performance obligation is recognized as revenue when control is transferred
for the related goods or services. For performance obligations which consist of licenses and other promises, the Company
utilizes  judgment  to  assess  the  nature  of  the  combined  performance  obligation  to  determine  whether  the  combined
performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring
progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of
performance and related revenue recognition.

Upfront  payments  and  fees  are  recorded  as  deferred  revenue  upon  receipt  or  when  due  until  the  Company
performs its obligations under these arrangements. Amounts expected to be recognized as revenue within the 12 months
following the balance sheet date are classified as current portion of deferred revenue in the accompanying balance sheets.
Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as
deferred  revenue,  net  of  current  portion.  Amounts  are  recorded  as  accounts  receivable  when  the  Company’s  right  to
consideration is unconditional.

Comprehensive Loss

Comprehensive 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 loss includes net loss and the change in accumulated
other comprehensive loss for the period. Accumulated other comprehensive loss consisted entirely of unrealized gains and
losses on available-for-sale marketable securities at December 31, 2020 and 2019.

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.

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,  ASU  2016-02  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.  The  Company  is  currently  evaluating  the  impact  of  adopting  this  guidance  on  the  Company’s  financial
statements. The Company currently expects that its operating lease commitments will be subject to the new standard and
recognized as right-of-use assets and operating lease liabilities upon adoption of this standard, which will increase the total
assets and total liabilities that it reports relative to such amounts presented prior to adoption.  

In  June  2016,  the  FASB  issued  ASU  No.  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 will be effective
for the Company for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years. Early
adoption is permitted and the Company plans to adopt ASU 2016-13 on January 1, 2021. The Company is implementing
the related internal controls, business processes, and accounting policies related to both the implementation of, and ongoing
compliance  with,  the  new  guidance.  The  impact  on  the  operating  results  or  consolidated  statements  of  cash  flows  is
expected to be immaterial.

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.

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 $22.4 million and $6.3 million for the years ended December 31, 2020
and December 31, 2019, 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.

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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, 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  intend  to  move  to  dismiss  the
consolidated amended complaint and discovery is stayed pending resolution of that motion.

The  Company  intends  to  vigorously  defend  the  action.  However,  whether  or  not  the  claims  are  successful,  this
type of litigation is often expensive. Due to the early stages of this matter and unspecified damages sought, at this time, the
Company  is  unable  to  estimate  the  potential  loss  or  range  of  losses.  The  Company,  however,  will  continue  to  evaluate
information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a
loss has been incurred and the amount of the loss is reasonably estimable.

9. Term Loan

In April 2016, the Company entered into a $1.0 million term loan (the “Term Loan”). On January 25, 2019, the
Company amended the Term Loan to increase the Company’s borrowing capacity to $5.0 million, which amount remains
secured by the Company’s certificates of deposit, money market account, investment property and deposit or investment
accounts.  As  amended,  the  Term  Loan  bears  interest  at  the  greater  of  the  prime  rate  less  1%  and  4.25%.  The  effective
interest rate was 4.25% and 4.40% for the years ended December 31, 2020 and 2019, respectively. Under the Term Loan,
the Company was required to make monthly interest-only payments through January 2020 and is required to make 36 equal
monthly payments of principal plus accrued interest thereafter through January 2023. Interest expense under the Term Loan
was approximately $183,000 and $209,000 for the years ended December 31, 2020 and 2019, respectively. The outstanding
balance on the Term Loan totaled $3.5 million and $5.0 million as of December 31, 2020 and 2019, respectively.

Future maturities of the Term Loan as of December 31, 2020 are as follows:

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

As of December 31, 2020, 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  27,568,802  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, 2020.

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”)  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  (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 on January 1, 2020 and each January 1st thereafter during the term of the 2019 Plan by 4% of the
number of shares of the Company’s common stock outstanding on December 31st of the preceding calendar year or such
lesser number of shares determined by the Board.

As of December 31, 2020, 2,749,830 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.

(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, 2020 and 2019.

The weighted average grant date fair value per share of stock options granted during the years ended December
31, 2020 and 2019 was $23.25 and $11.92, respectively. The aggregate intrinsic value of stock options exercised during the
years ended December 31, 2020 and 2019 was $633,000 and $7,225,000, respectively.

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

31, 2020 and 2019 was approximately $2,389,000 and $1,322,000, 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 on January 1, 2020 and each January 1st thereafter until expiration of the ESPP,
in  an  amount  equal  to  the  lesser  of  (i)  1%  of  the  number  of  shares  of  the  Company’s  common  stock  outstanding  on
December  31st  of  the  preceding  calendar  year,  (ii)  480,000  shares  of  common  stock  and  (iii)  a  number  of  shares  of
common stock determined by the administrator of the ESPP. As of December 31, 2020, no shares of common stock had
been issued pursuant to the ESPP and 240,000 shares were reserved for future issuance thereunder.

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:

Based on the Company’s history of losses, the Company recorded a full valuation allowance against its deferred
tax assets as of December 31, 2020. The Company increased its valuation allowance by approximately $11.9 million for
the  year  ended  December  31,  2020.  The  Company  intends  to  maintain  a  valuation  allowance  until  sufficient  positive
evidence exists to support a reversal of the allowance.

As of December 31, 2020, the Company had federal and state net operating loss carryforwards of $103.2 million
and  $105.0  million,  respectively,  some  of  which  begin  to  expire  in  the  year  ending  December  31,  2036.  Approximately
$80.4 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 $6.8 million and $0.1 million, respectively, as of December 31,
2020.  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 2019 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,  2020,  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 (“CARES Act”) and the Consolidated Appropriations

Act, 2021 (“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

118

      
      
 
  
    
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

have 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 that stipulates that eligible employees can elect to contribute to the 401(k)
plan, subject to certain limitations, up to the lesser of the statutory maximum or 100% of eligible compensation on a pre-
tax basis. For the years ended December 31, 2020 and 2019 the Company did not provide any contributions to this plan.

16. Subsequent Events

The  Company  has  evaluated  subsequent  events  through  the  filing  date  of  this  Form  10-K  with  the  SEC  and

determined that there have been no events that have occurred that would require adjustments to our disclosures.

Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the
effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities
Exchange  Act  of  1934,  as  amended,  or  the  Exchange  Act,  as  of  December  31,  2020.  Management  recognizes  that  any
controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving
their  objectives  and  management  necessarily  applies  its  judgment  in  evaluating  the  cost-benefit  relationship  of  possible
controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2020, our
Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures
were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

During the fourth quarter of 2020, we implemented a new Enterprise Resource Planning, or ERP, system. As a
result  of  this  implementation,  we  modified  certain  existing  internal  controls  as  well  as  implemented  new  controls  and
procedures related to the new ERP system. Except with respect to the continued implementation of the ERP system, there
were no changes in our internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d 15(f) under the
Exchange  Act)  that  occurred  during  the  fourth  quarter  of  2020  that  have  materially  affected,  or  are  reasonably  likely  to
materially affect, our internal controls over financial reporting.

Report of Management on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting
(as defined in Rule 13a-15(f) under the Exchange Act). Under the supervision of and with the participation of our Principal
Executive Officer and Principal Financial Officer, our management assessed the effectiveness of our internal control over
financial report as of December 31, 2020 based on the criteria set forth by the Committee of Sponsoring Organizations of
the  Treadway  Commission  in  "Internal  Control-Integrated  Framework"  (2013).  Based  on  this  assessment,  management
concluded that our internal control over financial reporting was effective as of December 31, 2020.

This Annual Report does not include an attestation report of our independent registered public accounting firm on
our  internal  control  over  financial  reporting  due  to  an  exemption  established  by  the  JOBS  Act  for  "emerging  growth

AMENDMENT TO LICENSE AGREEMENT AND SRA

THIS  AMENDMENT  TO  LICENSE  AGREEMENT  AND  SRA  (this  “AMENDMENT”)  is  made  and
entered  into  as  of  this  25th  day  of  April  2020,  to  be  effective  as  of  January  31,  2020  (the  “AMENDMENT
EFFECTIVE DATE”) by and between Yale University, a nonprofit corporation organized and existing under and
by  virtue  of  a  charter  granted  by  the  general  assembly  of  the  Colony  and  State  of  Connecticut  (“YALE”),  and
NextCure,  Inc.,  a  corporation  organized  and  existing  under  the  laws  of  the  State  of  Delaware  (“LICENSEE”).
YALE and LICENSEE are each referred to herein, individually, as a “party” and, collectively, as the “parties.”

WHEREAS, the parties entered into that certain License Agreement effective as of December 29, 2015 (as
amended to date, the “Existing License Agreement”) and the parties entered into that certain Corporate Sponsored
Research Agreement effective as of December 29, 2015 (as amended to date, the “Existing SRA”); and

WHEREAS, the Parties desire to amend the Existing License Agreement and the Existing SRA as more

particularly set forth in this AMENDMENT, or as the context of this AMENDMENT may require.

NOW, THEREFORE, in consideration of the mutual promises, representations, warranties and covenants
set  forth  in  this  AMENDMENT,  and  for  other  good  and  valuable  consideration,  the  receipt  and  sufficiency  of
which are hereby acknowledged, the parties hereto hereby agree as follows:

I.    AMENDMENTS TO DEFINITIONS

1.         Definitions and Phrases.

1.1       Capitalized terms used, but not defined, in this AMENDMENT shall have the respective meanings

ascribed to such terms in the Existing License Agreement, or the Existing SRA, as applicable.

1.2              Any  reference  to  “the  AGREEMENT”  or  “this  AGREEMENT”  with  respect  to  the  Existing
License  Agreement  shall  mean  the  Existing  License  Agreement,  as  amended  by  this  AMENDMENT.  Any
reference  to  “the  Agreement”  or  “this  Agreement”  with  respect  to  the  SRA  shall  mean  the  Existing  SRA,  as
amended by this AMENDMENT.

II.  AMENDMENTS TO EXISTING SRA

1.         Amendment to Section 2 of the Existing SRA. Section 2 of the Existing SRA shall be amended by
adding Section 2(c), as follows:

“(c) UNIVERSITY and PRINCIPAL INVESTIGATOR shall use all reasonable efforts to ensure that any
future  collaborations  or  commitments  with  a  third  party  (“THIRD  PARTY  OBLIGATIONS”)  do  not
conflict  with  the  rights  of  SPONSOR  under  this  Agreement.  UNIVERSITY  and  PRINCIPAL
INVESTIGATOR  shall  promptly  notify  SPONSOR  if  it  reasonably  believes  that  a  THIRD  PARTY
OBLIGATION conflicts with, or is reasonably

likely  to  conflict  with,  or  would  otherwise  adversely  affect  the  rights  of  SPONSOR  under  this
Agreement.”

2.         Amendment to Section 8(e) of the Existing SRA. The following paragraph shall be inserted at the
end of Section 8(e) of the Existing SRA:

“Promptly after SPONSOR’s written request, the UNIVERSITY shall disclose to SPONSOR in such form
and  media  as  may  be  reasonably  requested  by  SPONSOR  any  documentation,  materials,  or  other
information  concerning  the  INVENTION,  including  those  items  in  the  possession  and  control  of  the
UNIVERSITY 
the  LICENSE
AGREEMENT.”

that  would  be  considered  LICENSED 

INFORMATION  under 

3.         Amendment to Section 8(k) of the Existing SRA. The first sentence of Section 8(k) of the Existing
SRA shall be amended and restated in its entirety as follows:

“Subject  to  UNIVERSITY’s  legal  and  contractual  obligations  to  third  parties  existing  as  of  the
EFFECTIVE  DATE  or  entered  into  during  the  term  of  this  AGREEMENT  and  not  in  violation  of  the
LICENSE  AGREEMENT,  during  the  term  of  this  AGREEMENT,  SPONSOR  shall  have  the  right  to
request  that  UNIVERSITY  commence  a  transfer  to  or  sharing  with  SPONSOR  or  its  designee  of
LICENSED INFORMATION and RESEARCH RESULTS reasonably necessary for the establishment by
SPONSOR of a system for the screening and identification of targets as described in Exhibit A.”

4.         Amendment to Scope of Research and Budget in the Exiting SRA. The parties agree to extend the

term of the SRA for one (1) additional year (i.e., through December 31, 2021), based on a mutually acceptable
work plan and a budget consistent with current funding. Appendix E contains a draft work plan that the parties
shall finalize prior to the end of the current term.

II. AMENDMENTS TO LICENSE AGREEMENT

1.                  Amendment  to  Section  2.28  of  the  Existing  License  Agreement.  Section  2.28  of  the  Existing
License Agreement shall be amended and restated in its entirety as follows:

“2.28 “LICENSED INFORMATION” shall mean all information, data, know-how and the like, in any
form, whether or not patentable, that are useful for the discovery, development, manufacture, use, or sale
of one or more LICENSED PRODUCTS, or for the practice of the LICENSED METHODS and are:

(a)        owned or co-owned by YALE as of the EFFECTIVE DATE; and

(b)                the  Research  Results  (as  defined  in  the  SRA)  discovered  or  developed  in  or  on  behalf  of
(including,  without  limitation,  by  outsourced  third  parties  and  consultants)  the  CHEN  LAB  as  a
result of the Research (as defined in the SRA) under the SRA;

in each case, to the extent disclosable and licensable (including on a non-exclusive basis as contemplated
by this AGREEMENT) by YALE to LICENSEE without

causing  (i)  YALE  to  be  in  contractual  breach  of  an  agreement  between  YALE  and  a  third  party  either
existing as of the EFFECTIVE DATE or entered into on or after the EFFECTIVE DATE without violating
or  being  inconsistent  with  any  of  the  requirements  of  this  AGREEMENT  or  (ii)  liability  of  YALE  to  a
third party.

For  the  avoidance  of  doubt,  LICENSED  INFORMATION  does  not  include  any  patents  or  patent
applications included within the LICENSED PATENTS.”

2.         Amendment to Section 3 of the Existing License Agreement. Section 3 of the Existing License
Agreement shall be amended by inserting a new Section 3.8 in its entirety as follows:

“3.8 If YALE files a patent application anywhere in the Territory for any modification of or improvement
or  enhancement  to,  inventions  claimed  under  the  LICENSED  PATENTS,  YALE  shall  provide  written
notice  to  LICENSEE  within  [***]  after  becoming  aware  of  any  such  modification,  improvement  or
enhancement, and shall provide to LICENSEE copies of the patent application, all invention disclosures
related  thereto,  and  other  documents  that  disclose  such  modification,  improvement  or  enhancement  (in
addition to the patent application). Such disclosure shall contain sufficient detail to enable (i) both parties
to determine whether such disclosures contains patentable subject matter, and (ii) LICENSEE to evaluate
whether to exercise the option set forth in Section 3.5.”

3.                  Amendment  to  Section  3.4(a)(i)  of  the  Existing  License  Agreement.  Section  3.4(a)(i)  of  the
Existing License Agreement shall be amended and restated in its entirety as follows:

“Except on behalf of LICENSEE,

(i) YALE shall not enter into any agreement or arrangement by or on behalf of the CHEN LAB, or

permit the CHEN LAB to, directly or indirectly engage in, and

(ii)  the  CHEN  LAB  shall  not,  directly  or  indirectly,  engage  in,  or  enter  into  any  agreement  or

arrangement for

any  research,  development,  manufacturing  or  other  activities  in  which  the  LICENSED  PATENTS  or
LICENSED  PRODUCTS  are  used  by  a  third  party  for  a  pharmaceutical  or  biological  composition  the
primary mechanism of action of which is, by design, to bind to any of the molecular targets identified on
Appendix  D  attached  hereto  (A)  for  COMMERCIAL  PURPOSES  or  (B)  with  a  COMMERCIAL
ENTITY.

For  clarity,  YALE  shall  be  permitted  to  engage  in  any  such  activities  (subject  to  the  exclusivity  of  the
LICENSE granted by YALE hereunder); provided, that they do not involve CHEN or the CHEN LAB.”

4.                  Addition  of  Appendix  D  to  the  Existing  License  Agreement.  A  new  Appendix  D,  in  the  form
attached  to  this  AMENDMENT  as  Appendix  D,  shall  be  added  to  the  Existing  License  Agreement,
provided that, effective on [***], [***] shall be removed

from Appendix D. YALE shall have no further obligations to LICENSEE in regards to [***].

III. GENERAL

License Agreement or the Existing SRA are modified or changed by this AMENDMENT and (b) the terms

of  the  License  Agreement,  YALE  shall  promptly  disclose  to  LICENSEE  any  such  invention  disclosures
that should have been disclosed to LICENSEE, including but not limited to invention disclosures related to
[***] and [***].

3.              Effective  Date.  This  AMENDMENT  shall  be  effective  from  and  after  the  AMENDMENT
EFFECTIVE DATE.
