Item 1. Business

PART I 

Overview

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

a 

is 

Our 

first-in-class 

lead  product 

immunomedicine 

candidate,  NC318, 

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 was presented in November 2019 at the Society for Immunotherapy of
Cancer, or SITC, annual meeting. As of November 9, 2019, NC318 had been well tolerated in the Phase 1 portion of the
trial  and  only  one  dose-limiting  toxicity  had  been  observed.  Most  treatment-related  adverse  events  were  easily
manageable, asymptomatic or mild or moderate. Data from the trial indicate activity in multiple tumor types, including a
complete  response  and  a  partial  response  in  patients  with  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 and expect to announce initial data from the Phase 2
portion  by  the  end  of  2020.  In  addition,  in  mid-2020,  we  intend  to  initiate  a  Phase  2  clinical  trial  to  evaluate  NC318  in
combination with standard of care chemotherapies in patients with advanced or metastatic solid tumors. 

targeting 

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 the FDA, accepted our investigational new drug application, or IND, for NC410 in the
first quarter of 2020 and we intend to initiate a Phase 1/2 clinical trial in patients with advanced or metastatic solid tumors
in the second quarter of 2020.

Our  approach  to  identifying  targets  for  new  immunomedicines  is  based  on  our  FIND-IO  platform.  FIND-IO
embodies a rational approach to the discovery of novel cell surface and secretory molecules that drive functional immune
responses.  We  use  our  immunology  knowledge,  experience  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

4

Table of Contents

immunomedicines  that  counteract  these  outcomes  and  to  further  validate  and  advance  our  product  candidates.  We  have
identified multiple novel targets using our FIND-IO platform, including those for which certain of our research programs
are being designed to target. In addition, the immunosuppressive properties of S15, the target of NC318, were discovered
using a predecessor of our FIND-IO platform.

NC318, our lead immunomedicine program, is a monoclonal antibody targeting S15, which is expressed on highly
immunosuppressive  cells  called  M2  macrophages  and  on  tumor  cells.  The  immunosuppressive  properties  of  S15  were
discovered in 2015 at Yale University, or 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 this S15-
mediated  immune  suppression  and  restore  T  cell  function  and  anti-tumor  immunity  in  the  tumor  microenvironment,  or
TME,  which  we  believe  will  reduce  and  kill  tumors.  We  believe  NC318  has  the  potential  to  treat  multiple  cancer
indications because S15 is expressed in multiple tumor types and has a unique ability to modulate immune responses in the
TME.  In  addition,  because  S15  and  PD-L1  expression  in  tumors  generally  appear  to  be  non-overlapping,  we  believe
NC318  may  be  well  suited  to  treat  patients  who  are  not  responding  to  PD-1/PD-L1  directed  cancer  therapies.  We  are
initially evaluating NC318 for the treatment of advanced or metastatic solid tumors, including ovarian cancer, non-small
cell  lung  cancer,  or  NSCLC,  head  and  neck  squamous  cell  carcinoma,  or  HNSCC,  and  triple-negative  breast  cancer,  or
TNBC.

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

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.

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

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

the United Technologies Corporation Professor in Cancer Research and Professor of Immunobiology, of Dermatology and

5

Table of Contents

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

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

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 and NC410. In October 2018,
we initiated a Phase 1/2 clinical trial evaluating 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 was presented at the SITC annual meeting in November 2019. We began enrolling patients in
the Phase 2 portion of the trial in October 2019 and expect to announce initial data from the Phase 2 portion
by  the  end  of  2020.  In  mid-2020,  we  intend  to  initiate  a  Phase  2  clinical  trial  to  evaluate  NC318  in
combination with standard of care chemotherapies in patients with advanced or metastatic solid tumors. For
NC410, the FDA accepted our IND in the first quarter of 2020 and we intend to initiate a Phase 1/2 clinical
trial in the second quarter of 2020.

Building an oncology pipeline of novel targets for new immunomedicines focused on non-responders. We
are  leveraging  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 expect 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 
to  support
development  of  our  pipeline  and  advancement  of  our  product  candidates  into  and  through  clinical
development. The facility has an initial production capacity of 1,000 liters with additional room for expansion
and is designed to operate as a multi-product facility. Compared to working with third-party manufacturers,
we  believe  our  facility  provides  better  quality  assurance,  greater  control  in  scheduling  and  prioritizing
manufacturing activities and enhanced capital efficiency.

technology 

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

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

Remodeling the TME and overcoming its immunosuppressive properties is a major focus of cancer research and
drug development. Checkpoint inhibitors are a drug class designed to counteract certain tumor defenses against the immune
system.  Currently  approved  checkpoint  inhibitors  were  developed  for  the  treatment  of  cancer  based  on  the  belief  that
inactivation of the immune system by checkpoints could be reversed to reactivate the immune system to recognize and

7

Table of Contents

attack the tumor. Therapies against checkpoints, such as PD-L1, PD-1 and CTLA-4, have produced impressive results in
the clinic across an array of cancers and have been approved for several malignancies. However, despite the recent success
of these checkpoint inhibitors, efficacy has been limited. It is estimated that up to 60% to 70% of cancer patients, including
those with melanoma, renal cell cancer, colorectal cancer, NSCLC, urothelial cancer and HNSCC, do not respond to single-
agent therapy with checkpoint inhibitors. Many of the patients who are non-responders possess so called “cold” tumors that
do  not  contain  meaningful  numbers  of  T  cells  that  recognize  their  tumors.  In  addition,  some  patients  develop  resistance
after  initial  treatment  with  these  checkpoint  inhibitors.  This  limited  efficacy  highlights  the  importance  of  our  effort  to
identify  novel  targets  and  molecular  pathways  responsible  for  tumor  immune  evasion  mechanisms  that  we  believe  will
work independently from current targets for cancer immunotherapy.

Our Approach to Developing Immunomedicines for Cancer

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

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

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

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

As  shown  in  the  figure  below,  our  product  candidates  target  a  variety  of  cell  types  in  the  immune  system.  For
example, NC318 targets macrophages and tumor cells and prevents suppressive myeloid cells from negatively regulating T
cells, 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 our preclinical studies, we initiated a Phase
1/2 clinical trial of NC318 in patients with advanced or metastatic solid tumors in October 2018. We completed enrollment
of the Phase 1 portion of this trial in August 2019 and preliminary data from the Phase 1 portion was presented at the SITC
annual  meeting  in  November  2019.  We  began  enrolling  patients  in  the  Phase  2  portion  of  the  trial  in  October  2019  and
expect to announce initial data from the Phase 2 portion by the end of 2020. In addition, we may develop a complementary
diagnostic for NC318 if we determine it is advisable. We have exclusive worldwide rights to NC318.

S15 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.

Table of Contents

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

S15 is Highly Immunosuppressive in the TME

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

NC318 is Designed to Block Immunosuppressive Activity Induced by S15

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

First in-Human Phase 1/2 Clinical Trial

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

tolerability  of  NC318, 

the  safety  and 

the  maximum 

to  define 

to  assess 

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 have 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  trial  were  NSCLC  (13  patients),  ovarian  (seven  patients),  melanoma  (seven
patients),  breast  (four  patients)  and  colorectal  (three  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 was presented in November 2019 at the SITC annual meeting. As of
November 9, 2019, 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  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  November  9,  2019,  durable  responses  observed  include  one  complete  response,  which  remained
ongoing at 55 weeks, and one partial response, which remained ongoing at 28 weeks, both in NSCLC patients, as well as
14 patients 

12

Table of Contents

with  stable  disease,  which  remained  ongoing  for  between  16  and  42  weeks.  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  14
patients with stable disease, four patients have NSCLC, with stable disease ongoing for between 16 and 40 weeks. Three
NSCLC patients (out of 13 NSCLC patients in total) had not been in the study long enough to confirm the status of their
disease.

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

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

Phase 2 Combination Clinical Trial

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

Preclinical Data

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

13

Table of Contents

Treatment with 5G12 Reduced Tumor Growth and Increased Survival

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

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

Treatment with 5G12 Delayed Tumor Metastasis in Lung Model

Based  on  in  vitro  studies,  we  understand  that  S15  drives  an  increase  in  pro-inflammatory  and  pro-tumorigenic
cytokines, such as IL-1β, IL-6 and TNF-α. As indicated in the figure below, when human peripheral blood mononuclear
cells, or PBMCs, which are blood cells that are critical components in the immune system, were cultured in the presence of
S15,  the  amount  of  pro-inflammatory  and  pro-tumorigenic  cytokines  increased,  indicating  an  immunosuppressive
environment.  However,  when  human  PBMCs  were  cultured  with  S15  protein  and  5G12  or  NC318,  the  amount  of  pro-
inflammatory and pro-tumorigenic cytokines was reduced relative to when cultured with S15 and a control antibody. In

14

addition, 5G12 and NC318 promoted the ability of human T cells to proliferate and produce interferon-gamma, or IFN-γ.
These  data,  which  are  shown  in  the  figures  below,  suggest  that  5G12  and  NC318  have  the  potential  to  block  immune
suppression mediated by S15.

NC318 Decreased Inflammatory Cytokines

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 intend to initiate a Phase 1/2 clinical
trial  in  patients  with  advanced  or  metastatic  solid  tumors  in  the  second  quarter  of  2020.  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

15

Table of Contents

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.

16

Table of Contents

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

In another preclinical study with human cells, we observed that NC410 promoted increases in the cytokines IL-
2 and TNF-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.

17

Table of Contents

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

18

Table of Contents

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.

NC410 Decreased Tumor Volume

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 planned clinical trials of NC410 in humans.

19

Table of Contents

The FDA accepted our IND for NC410 in the first quarter of 2020 and we intend to initiate a Phase 1/2 clinical
trial in the second quarter of 2020 in patients with advanced or metastatic solid tumors in a variety of tumor types including
lung, ovarian and pancreatic cancer.

Our Research Programs

In  addition  to  NC318  and  NC410,  we  are  also  pursuing  preclinical  evaluation  of  other  potential  novel
immunomodulatory  molecules.  Among  these  is  an  antibody  that  targets  a  novel  member  of  the  B7-family  of
immunomodulatory proteins. In our preclinical studies, this antibody has shown highly reproducible and potent anti-tumor
activity  with  in  vivo  modeling  and  appears  to  involve  an  important  immunomodulatory  pathway  in  the  TME  that  may
complement  the  activity  of  NC318  and  NC410.  Consistent  with  our  focus  on  patients  who  do  not  respond  to  current
therapies,  patients  whose  cancer  progresses  despite  treatment  and  patients  with  cancer  types  that  are  not  adequately
addressed by currently available therapies, the target of this antibody appears to be non-overlapping with the expression of
both S15 and PD-L1 on tumor cells.

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

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

Our FIND-IO Discovery Engine

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

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

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

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

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

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

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

Our Collaboration Agreements

Agreements with Yale University

License Agreement with Yale

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

22

Table of Contents

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

Former Research and Development Collaboration with Lilly

Effective March 3, 2020, Eli Lilly and Company, or Lilly, terminated the multi-year collaboration agreement that
we had entered into with Lilly in November 2018, or the Lilly Agreement, focused on the discovery and development of
immunomedicines for oncology using our FIND-IO platform. Under the agreement, we granted Lilly the exclusive option
to  obtain  worldwide  exclusive  licenses  to  research,  develop,  manufacture  and  commercialize  multiple  compounds  and
products directed to oncology targets identified through our research collaboration. We received an upfront, non-refundable
payment of $25.0 million in cash and a $15.0 million equity investment from Lilly upon entering into the agreement. Lilly
was also required to pay us quarterly research and development support payments as well as option exercise fees upon the
exercise of options by Lilly, development and regulatory milestone payments, sales milestone payments and royalties. In
connection with the termination of the Lilly Agreement, we are no longer eligible to receive future amounts thereunder.

Manufacturing

We  have  a  purpose-built,  dedicated,  state-of-the-art  cGMP  manufacturing  facility  that  utilizes  single-use
technology to support our pipeline and advance our product candidates into and through clinical development. The facility
has an initial production capacity of 1,000 liters and was designed with additional room for expansion to support multiple
product  candidates.  The  investment  in  our  manufacturing  facility  is  a  critical  element  of  our  ability  to  quickly  identify
whether a candidate is likely to be successful and to facilitate an efficient development path. While other companies may
need to work with third parties for antibody production, we can do so in our own facility. Compared to working with third-
party manufacturers, we believe our facility provides better quality assurance, greater control in scheduling and prioritizing
manufacturing  activities  and  enhanced  capital  efficiency.  We  are  currently  manufacturing  all  of  the  drug  supply  for  our
preclinical  studies  and  our  Phase  1/2  clinical  trial  of  NC318  and  intend  to  expand  our  cGMP  manufacturing  capacity,
including to provide the drug supply for future clinical trials of NC318. As we advance the development of our growing
pipeline  of  product  candidates,  we  will  continue  to  evaluate  the  merits  of  further  expanding  our  internal  manufacturing
capabilities,  including  for  the  production  of  commercial  drug  supply,  as  compared  to  collaborating  with  third-party
manufacturers. 

Competition

The biotechnology and pharmaceutical industries, and the immuno-oncology subsector, are characterized by rapid
evolution  of  technologies,  fierce  competition  and  strong  defense  of  intellectual  property.  We  believe  that  our  programs,
platforms, technology, knowledge, experience and scientific resources provide us with competitive advantages, but we also
face  competition  from  pharmaceutical  and  biotechnology  companies,  academic  institutions,  governmental  agencies  and
public and private research institutions, among others. Our competitors include larger and better funded biopharmaceutical,
biotechnology and therapeutics companies, including companies focused on cancer immunotherapies,

23

Table of Contents

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, 2019, our intellectual property portfolio
includes, on a worldwide basis, 18 pending foreign patent applications relating to NC318 and NC410, one pending U.S.
patent application relating to NC318, one pending U.S. patent application relating to NC410 and additional pending patent
applications  for  other  discovery  and  research  programs.  Patents  resulting  from  our  patent  applications  for  NC318  and
NC410, if issued, are expected to expire beginning in 2037 absent any patent term adjustments or extensions.

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

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

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

Government Regulation

Government Regulation and Product Approval

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

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

Review and Approval for Licensing Biologics in the United States

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

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

25

Table of Contents

·

·

·

·

·

·

·

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

26

Table of Contents

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.

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.

27

Table of Contents

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.

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

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

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

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

Pediatric Studies

Under the Pediatric Research Equity Act, a BLA or BLA supplement must contain data that are adequate to assess

the safety and effectiveness of the drug product for the claimed indications in all relevant pediatric subpopulations, and to

29

Table of Contents

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

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

Post-Approval Requirements

Any  products  manufactured  or  distributed  pursuant  to  FDA  approvals  are  subject  to  pervasive  and  continuing
regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, reporting
of  certain  deviations  and  adverse  experiences,  product  sampling  and  distribution  and  advertising  and  promotion  of  the
product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are
subject to FDA review and approval. There also are continuing user fee requirements, under which FDA assesses an annual
program fee for each product identified in an approved BLA. Biologic manufacturers and their third-party contractors are
required  to  register  their  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;

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;

30

Table of Contents

·

·

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  and  criminal  fines  and  agreements  that
materially  restrict  the  manner  in  which  a  company  promotes  or  distributes  products.  The  federal  government  has  levied
large  civil  and  criminal  fines  against  companies  for  alleged  improper  promotion,  and  has  also  requested  that  companies
enter into consent decrees and permanent injunctions under which specified promotional conduct is changed or curtailed.

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

Patent Term Restoration and Marketing Exclusivity

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

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

Biosimilars and Marketing Exclusivities

The  Biologics  Price  Competition  and  Innovation  Act,  or  BPCIA,  created  an  abbreviated  approval  pathway  for
biological product candidates shown to be highly similar to or interchangeable with an FDA licensed 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,  2020”,  authorizing
appropriations through September 30, 2020 to fund operations of certain governmental agencies, including the FDA. 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 peptides” are no longer excluded from being
regulated as biologics. In addition, the Further Consolidated Appropriations Act, 2020 clarifies exclusivity and procedural
issues related to certain biologics approved as drugs pursuant to new drug applications, or NDAs, to be the subject of an
approved  BLA,  or  transition  biological  products.  The  law  also  incorporates  provisions  intended  to  reduce  price  and
increase  competitiveness  in  the  pharmaceutical  industry.  The  law  amends  the  FDCA  to  create  a  private  right  of  action
against NDA or BLA holders that refuse to provide sufficient quantities of samples of an approved reference product to
generic and biosimilar developers. In July 2018, the FDA released its Biosimilars Action Plan to improve the efficiency of
the  biosimilar  and  interchangeable  product  development  and  approval  process.  The  Further  Consolidated Appropriations
Act, 2020 is consistent with FDA guidance documents issued in December 2018 that were intended to 

32

Table of Contents

advance the agency’s biosimilars policy framework. The implementation of the Further Consolidated Appropriations Act,
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.

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

·

·

The federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting,
receiving,  offering  or  paying  any  remuneration  (including  any  kickback,  bribe  or  rebate),  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 or recommendation of any good, facility, item or service for which payment may
be  made,  in  whole  or  in  part,  under  the  Medicare  and  Medicaid  programs,  or  other  federal  healthcare
programs.  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  Law  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, knowingly presenting, or causing to be presented,
claims  for  payment  of  government  funds  that  are  false  or  fraudulent,  or  knowingly  making,  or  using  or
causing  to  be  made  or  used,  a  false  record  or  statement  material  to  a  false  or  fraudulent  claim  to  avoid,
decrease,  or  conceal  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 such individuals

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  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 executing 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;

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

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

We  will  be  required  to  spend  substantial  time  and  money  to  ensure  that  our  business  arrangements  with  third
parties comply with applicable healthcare laws and regulations. Even then, governmental authorities may conclude that our
business  practices  do  not  comply  with  current  or  future  statutes,  regulations  or  case  law  involving  applicable  fraud  and
abuse or other healthcare laws and regulations. If governmental authorities find that our operations violate any of these

35

Table of Contents

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  new  methodology  by  which  rebates  owed  by  manufacturers
under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected;
increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the
rebate  program  to  individuals  enrolled  in  Medicaid  managed  care  organizations;  establishes  annual  fees  and  taxes  on
manufacturers of certain branded prescription drugs; and creates a new Medicare Part D coverage gap discount program in
which, as a condition of coverage of its products under Medicare Part D, manufacturers must agree to offer 70% 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
on certain individuals who fail to maintain qualifying health coverage for all or part of a year commonly referred to as the
“individual mandate.” In January 2018, President Trump signed a continuing resolution that delayed the implementation of
certain  ACA-mandated  fees,  including  the  so-called  “Cadillac”  tax  on  certain  high  cost  employer-sponsored  insurance
plans, the annual fee imposed on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain
health insurance providers based on market share and the medical device excise tax on non-exempt medical devices. The
Bipartisan  Budget  Act  of  2018,  among  other  things,  amended  the  ACA  to  create  a  new  Medicare  Part  D  coverage  gap
discount  program,  in  which  manufacturers  must  agree  to  offer  70%  point-of-sale  discounts  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. Additional legislative or regulatory changes related to the ACA remain possible.

In December 2018, a United States District Court Judge for the Northern District of Texas ruled that the 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. 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, there have been several recent U.S. Congressional inquiries and proposed and
enacted federal and state legislation designed to, among other things: bring more transparency to drug pricing;  reduce the
cost of prescription drugs under government payor programs; review the relationship between pricing and manufacturer

36

Table of Contents

patient programs; and reform government program reimbursement methodologies for drugs. The Trump Administration is
currently assessing additional proposals that are designed to affect drug pricing, such as tying U.S. drug prices to prices
outside the United States. Congress and the Trump Administration have each indicated that they will continue to seek new
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, on May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn and Matthew Bellina Right to
Try Act of 2017, or the Right to Try Act was signed into law. The law, among other things, provides a federal framework
for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that
are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without
enrolling  in  clinical  trials  and  without  obtaining  FDA  permission  under  the  FDA  expanded  access  program.  There  is  no
obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right
to Try Act.

Employees

As of December 31, 2019, we had 69 full-time employees, of which 86% were primarily engaged in research and
development  activities  and  39%  hold  M.D.  or  Ph.D.  degrees.  None  of  our  employees  is  represented  by  labor  unions  or
covered by collective bargaining agreements. We consider our relationship with our employees to be good.

Corporate Information and Access to SEC Reports

We  were  incorporated  in  Delaware  in  September  2015.  Our  primary  executive  offices  are  located  at  9000
Virginia  Manor  Road,  Suite  200,  Beltsville,  Maryland  20705  and  our  telephone  number  is  (240)  399-4900.  We  make
available, free of charge, on our website at www.nextcure.com, our annual reports on Form 10-K, quarterly reports on Form
10-Q, current reports on Form 8-K and any amendments to such reports as soon as reasonably practicable after such reports
are  electronically  filed  with,  or  furnished  to,  the  SEC.  The  contents  of  our  website  are  not  incorporated  into  this
Annual Report.

Item 1A. Risk  Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described
below together with all of the other information in this Annual Report, including our financial statements and the related
notes and the information described in the section entitled “Management’s Discussion and Analysis of Financial Condition
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 $33.7 million and $22.8 million for the years ended December
31,  2019  and  2018,  respectively.  As  of  December  31,  2019,  we  had  an  accumulated  deficit  of  $81.0  million.  We  have
funded our operations to date primarily with proceeds from public offerings of our common stock, private placements of
our preferred stock and upfront fees received under the Lilly Agreement. 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

37

Table of Contents

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  of  NC318  for  future  clinical
trials;

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

expand our operational, financial and management systems and increase personnel, including to support our
clinical development, manufacturing and commercialization efforts and our operations as a public company;

· maintain, expand and protect our intellectual property portfolio;

·

·

·

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

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

incur additional legal, accounting or other expenses in operating our business, including the additional costs
associated with operating as a public company.

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 trial for NC318 and other planned clinical trials for NC318 and NC410;

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

38

Table of Contents

·

·

·

·

receiving acceptance of INDs for future product candidates;

identifying and developing new product candidates;

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

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

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

·

·

·

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

addressing any competing technological and market developments;

negotiating  favorable  terms  in  any  collaboration,  licensing  or  other  arrangements  into  which  we  may  enter
and performing our obligations under such arrangements;

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

secrets and know-how;

·

·

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

attracting, hiring and retaining qualified personnel.

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

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

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

Our future capital requirements depend on many factors, including:

·

·

the  scope,  progress,  timing,  results  and  costs  of  researching  and  developing  NC318,  NC410  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  and  any  future
product candidates we develop, if clinical trials are successful;

39

Table of Contents

·

·

·

·

·

·

·

·

the  costs  of  manufacturing  NC318,  NC410  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 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 adverse 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,  2019,  we  had  $334.6  million  in  cash,  cash  equivalents  (excluding  restricted  cash)  and  marketable
securities. Based on our research and development plans, we expect that our existing cash, cash equivalents and marketable
securities will enable us to fund our operating expenses and capital expenditure requirements into the first 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 or research programs, technologies or grant licenses on terms that may not be
favorable to us. If we raise additional capital through public or private equity offerings, the terms of these securities may
include liquidation or other preferences that adversely affect our stockholders’ rights. Further, to the extent that we raise
additional  capital  through  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

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

We are early in our development efforts. We initiated our first clinical trial for NC318, our lead product candidate,
in October 2018, and we intend to initiate our first clinical trial for our second product candidate, NC410, in the second
quarter of 2020. Our ability to generate product revenues, which we do not expect will occur for several years, if ever, will

40

Table of Contents

depend heavily on the successful development and eventual commercialization of NC318, NC410 and any future product
candidates  we  develop,  which  may  never  occur.  Our  current  product  candidates  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;

· 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

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
relationships 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  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;

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.

42

Table of Contents

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.  We  may  experience
delays in completing our clinical trials or preclinical studies and initiating or completing additional clinical trials. Although
we initiated a Phase 1/2 clinical trial of NC318 in October 2018, we may experience delays in initiating or completing our
planned  clinical  trials  and  development  efforts.  Additionally,  we  cannot  be  certain  the  ongoing  and  planned  preclinical
studies or clinical trials for NC318, NC410 or any future product candidates will begin on time, not require redesign, enroll
an  adequate  number  of  subjects  on  time  or  be  completed  on  schedule,  if  at  all.  We  may  also  experience  numerous
unforeseen  events  during  our  clinical  trials  that  could  delay  or  prevent  our  ability  to  receive  marketing  approval  or
commercialize the product candidates we develop, including:

·

·

·

·

·

·

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;

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

43

Table of Contents

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 coronavirus;

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 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.

44

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

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

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

With the exception of NC318, all of our product candidates are still in the preclinical 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.

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

45

Table of Contents

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

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

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

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

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

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

46

Table of Contents

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.

The most common treatment-related adverse events reported in the Phase 1 portion of the Phase 1/2 clinical trial
of  NC318  as  of  November  9,  2019,  the  most  recent  date  for  which  we  have  reported  data  on  the  trial,  were  diarrhea,
infusion reactions, fatigue, headaches, pruritis, elevated amylase and elevated lipase. Most treatment-related adverse events
have  been  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. 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 which, while not necessarily adverse to the patient’s health, could substantially limit the
effectiveness  of  the  treatment.  In  addition  to  any  potential  side  effects  caused  by  the  product  or  product  candidate,  the
administration process or related procedures also can cause adverse side effects. If unacceptable adverse events occur, our
clinical trials or any future marketing authorization could be suspended or terminated.

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

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

In addition, we intend to pursue NC318 in part in combination with other therapies and may develop NC410 and
future product candidates in combination with other therapies, which exposes us to additional risks relating to undesirable
side effects or other properties. For example, the other therapies may lead to toxicities that are improperly attributed to our

47

Table of Contents

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  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.

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

The design and implementation of clinical trials is a complex process. We have limited experience designing and
implementing  clinical  trials,  and  we  may  not  successfully  or  cost-effectively  design  and  implement  clinical  trials  that
achieve  our  desired  clinical  endpoints  efficiently,  or  at  all.  A  clinical  trial  that  is  not  well  designed  may  delay  or  even
prevent  initiation  of  the  trial,  can  lead  to  increased  difficulty  in  enrolling  patients,  may  make  it  more  difficult  to  obtain
regulatory approval for the product candidate on the basis of the study results, or, even if a product candidate is approved,
could make it more difficult to commercialize the product successfully or obtain reimbursement from third-party payors.
Additionally, a trial that is not well-designed could be inefficient or more expensive than it otherwise would have been, or
we may incorrectly estimate the costs to implement the clinical trial, which could lead to a shortfall in funding. We also

48

Table of Contents

expect to continue to rely on third parties to conduct our pivotal clinical trials. See “—Risks Related to Reliance on Third
Parties—We rely or will rely on third parties to help conduct our ongoing and planned preclinical studies and clinical trials
for NC318, NC410 and any future product candidates we develop. If these third parties do not successfully carry out their
contractual  duties,  comply  with  regulatory  requirements  or  meet  expected  deadlines,  we  may  not  be  able  to  obtain
marketing approval for or commercialize NC318, NC410 and any future product candidates we develop, and our business
could be materially harmed.” Consequently, we may be unable to successfully and efficiently execute and complete clinical
trials that are required for BLA submission and FDA approval of NC318, NC410 or future product candidates. We may
require more time and incur greater costs than our competitors and may not succeed in obtaining regulatory approvals of
product candidates that we develop.

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

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

·

·

·

·

·

·

·

·

·

·

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.  Since  the  number  of  qualified  clinical  investigators  is  limited,  we  expect  to
conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the
number of patients who are available for our clinical trials at such sites. Moreover, because our current and potential future
product candidates may represent a departure from more commonly used methods for cancer treatment, potential patients
and their doctors may be inclined to use conventional therapies, such as chemotherapy, rather than enroll patients in our
ongoing or any future clinical trial.

49

Table of Contents

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 require us to abandon the trial altogether and could delay or prevent our
receipt of regulatory approval the applicable product candidate.

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

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

50

Table of Contents

identify the right patients for current or future product candidates, we believe that our success may depend, in part, on our
ability to develop complementary or companion diagnostics in collaboration with partners.

We  have  limited  experience  in  the  development  of  diagnostics  and,  as  such,  we  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

51

Table of Contents

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

52

Table of Contents

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 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 and future product
candidates in combination with other therapies, which exposes us to additional regulatory risks.

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

product candidates in combination with one or more currently approved cancer therapies. These combinations have not

53

Table of Contents

been  tested  before  and  may,  among  other  things,  fail  to  demonstrate  synergistic  activity,  may  fail  to  achieve  superior
outcomes relative to the use of single agents or other combination therapies, or may fail to demonstrate sufficient safety or
efficacy  traits  in  clinical  trials  to  enable  us  to  complete  those  clinical  trials  or  obtain  marketing  approval  for  the
combination therapy.

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

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

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

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

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

54

Table of Contents

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

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

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

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

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

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

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

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

55

Table of Contents

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

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

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

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

No  uniform  policy  for  coverage  and  reimbursement  for  products  exist  among  third-party  payors  in  the  United
States. Therefore, coverage and reimbursement for products can differ significantly from payor to payor. As a result, the
coverage determination process is often a time-consuming and costly process that may require us to provide scientific and
clinical  support  for  the  use  of  our  product  candidates  to  each  payor  separately,  with  no  assurance  that  coverage  and
adequate reimbursement will be applied consistently or obtained in the first instance. Furthermore, rules and regulations
regarding  reimbursement  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
new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for
drugs  that  are  inhaled,  infused,  instilled,  implanted  or  injected,  increases  the  minimum  Medicaid  rebates  owed  by
manufacturers  under  the  Medicaid  Drug  Rebate  Program  and  extends  the  rebate  program  to  individuals  enrolled  in
Medicaid  managed  care  organizations,  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.” In January
2018,  President  Trump  signed  a  continuing  resolution  that  delayed  the  implementation  of  certain  ACA-mandated  fees,
including the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on
certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based
on market share and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act of 2018,
among  other  things,  amended  the  ACA  to  create  a  new  Medicare  Part  D  coverage  gap  discount  program,  in
which  manufacturers  must  agree  to  offer  70%  point-of-sale  discounts  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.
Additional legislative or regulatory changes related to the ACA remain possible.

In December 2018, a United States District Court Judge for the Northern District of Texas ruled that the 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. 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.

Table of Contents

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.  This  has  resulted  in
aggregate reductions of Medicare payments to providers of, on average, 2% per fiscal year through 2029 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,  effective  January  1,  2014,  CMS  began  bundling  into  the  hospital  outpatient  prospective  payment  rate
the  Medicare  payments  for  most  laboratory  tests  ordered  while  a  patient  received  services  in  a  hospital  outpatient
setting. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which
could limit the amounts that federal and state governments will pay for healthcare products and services, which could result
in  reduced  demand  for  any  product  candidate  we  develop  or  complementary  or  companion  diagnostics  or  additional
pricing pressures.

CMS  may  develop  new  payment  and  delivery  models,  such  as  bundled  payment  models.  In  addition,  recently
there  has  been  heightened  governmental  scrutiny  over  the  manner  in  which  manufacturers  set  prices  for  their
marketed products, which has resulted in several U.S. Congressional inquiries and proposed and enacted federal and state  
 legislation 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.  The  Trump  Administration  is  currently  assessing
additional  proposals  that  are  designed  to  affect  drug  pricing,  such  as  tying  U.S.  drug  prices  to  prices  outside  the  United
States.  Congress  and  the  Trump  Administration  have  each  indicated  that  they  will  continue  to  seek  new  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.

in 

Individual  states 

increasingly  passed 

the  United  States  have  also 

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.

legislation  and 

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

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:

·

·

·

·

The federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting,
receiving,  offering  or  paying  any  remuneration  (including  any  kickback,  bribe,  or  rebate),  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 or recommendation of any good, facility, item or service for which payment may
be  made,  in  whole  or  in  part,  under  the  Medicare  and  Medicaid  programs  or  other  federal  healthcare
programs.  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 FCA, which
prohibits,  among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  claims  for  payment  of
government funds that are false or fraudulent, or knowingly making, or using or causing to be made or used, a
false record or statement material to a false or fraudulent claim to avoid, decrease, or conceal 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 such individuals 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  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  HIPAA  fraud  provisions,  which  prohibit  knowingly  and  willfully  executing  a  scheme  to  defraud  any
healthcare  benefit  program,  including  private  third-party  payors,  and  prohibit  knowingly  and  willfully
falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent
statement or representation, or 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 statutes or specific
intent to violate them.

HIPAA  and  its  implementing  regulations,  also  impose  specified  requirements  relating  to        the  privacy,
security  and  transmission  of  individually  identifiable  health  information  held  by  covered  entities,  which
include 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

60

Table of Contents

penalties, as well as criminal penalties. 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  with  which  we  collaborate  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.

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

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

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

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

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

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

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

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

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

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

Risks Related to Manufacturing

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

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

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

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

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

If we fail to develop 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  or  NC410.  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  trial  of  NC318.  We  intend  to  expand  our  manufacturing  capacity,  including  to  provide  drug
supply of NC318 for future clinical trials, which will require us to incur significant expenses. If one or more of our product
candidates  progress  to  late-stage  development,  we  may  incur  additional  significant  expenses  in  the  further  expansion  or
construction of manufacturing facilities and increases in personnel in order to manufacture product candidates in sufficient
quantities. We cannot assure you that we will be able to successfully manufacture product candidates at a larger scale in a
timely or economical manner, or at all. If we are unable to successfully increase our manufacturing scale or capacity, the
development,  testing  and  clinical  trials  of  our  current  or  future  product  candidates  may  be  delayed  or  infeasible,  and
regulatory  approval  or  commercial  launch  of  any  resulting  product  may  be  delayed  or  not  obtained,  which  could
significantly harm our business.

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

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

63

Table of Contents

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

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

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

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

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

The process of manufacturing immunomedicines, including our product candidates, is complex, time-consuming,

highly regulated and subject to several risks, including:

·

·

·

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

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

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

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

64

Table of Contents

process during the course of clinical development may require us to show the comparability of the product used in earlier
clinical phases or at earlier portions of a trial to the product used in later clinical phases or later portions of the trial.

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

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

Risks Related to Intellectual Property

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

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

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

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

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

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

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

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

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

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

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

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

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

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

66

Table of Contents

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

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

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

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

Competitors  may  infringe  our  patents  or  the  patents  of  our  licensors,  or  we  may  be  required  to  defend  against
claims of infringement. Countering infringement or unauthorized use claims or defending against claims of infringement
can  be  expensive  and  time-consuming.  Even  if  resolved  in  our  favor,  litigation  or  other  legal  proceedings  relating  to
intellectual property claims may cause us to incur significant expenses and could distract our technical and management
personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings,
motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be
negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could
substantially  increase  our  operating  losses  and  reduce  the  resources  available  for  development  activities  or  any  future
marketing, sales or distribution activities. We may not have sufficient financial or other resources to adequately conduct
such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings
more  effectively  than  we  can  because  of  their  greater  financial  resources  and  more  mature  and  developed  intellectual
property  portfolios.  Uncertainties  resulting  from  the  initiation  and  continuation  of  patent  litigation  or  other  proceedings
could have a material adverse effect on our ability to compete in the marketplace.

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

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

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

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

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

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

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

If we are found to infringe a third party’s valid and enforceable intellectual property rights, we could be required
to obtain a license from such third party to continue developing, manufacturing and marketing our product candidates and
technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if
we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access

68

Table of Contents

to  the  same  technologies  licensed  to  us,  and  it  could  require  us  to  make  substantial  licensing  and  royalty  payments.  We
could  be  forced,  including  by  court  order,  to  cease  developing,  manufacturing  and  commercializing  the  infringing
technology or product candidates. In addition, we could be found liable for monetary damages, including treble damages
and attorneys’ fees, if we are found to have willfully infringed a patent or other intellectual property right. A finding of
infringement could prevent us from manufacturing and commercializing our product candidates or force us to cease some
of  our  business  operations,  which  could  materially  harm  our  business.  Claims  that  we  have  misappropriated  the
confidential  information  or  trade  secrets  of  third  parties  could  have  a  similar  negative  impact  on  our  business,  financial
condition, results of operations and prospects.

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

While we are presently unaware of any claims or assertions by third parties with respect to our patents or other
intellectual property, we cannot guarantee that a third party will not assert a claim or an interest in any of such patents or
intellectual property. For example, a third party may claim an ownership interest in one or more of our, or our licensors’,
patents  or  other  proprietary  or  intellectual  property  rights.  A  third  party  could  bring  legal  actions  against  us  to  seek
monetary damages or enjoin clinical testing, manufacturing or marketing of the affected product candidate or product. If we
become involved in any litigation, it could consume a substantial portion of our resources and cause a significant diversion
of effort by our technical and management personnel. If any such action is successful, in addition to any potential liability
for damages, we could be required to obtain a license to continue to manufacture or market the affected product candidate
or product, in which case we could be required to pay substantial royalties or grant cross-licenses to patents. We cannot,
however,  assure  you  that  any  such  license  would  be  available  on  acceptable  terms,  if  at  all.  Ultimately,  we  could  be
prevented from commercializing a product, or forced to cease some aspect of our business operations as a result of claims
of  patent  infringement  or  violation  of  other  intellectual  property  rights.  Further,  the  outcome  of  intellectual  property
litigation is subject to uncertainties that cannot be adequately quantified in advance, including the demeanor and credibility
of witnesses and the identity of any adverse party. This is especially true in intellectual property cases, which may turn on
the testimony of experts as to technical facts upon which experts may reasonably disagree. Any of the foregoing could have
a material adverse effect on our business, financial condition, results of operations or prospects.

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

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

Adequate remedies may not exist in the event of unauthorized use or disclosure of our proprietary information.
The disclosure of our trade secrets would impair our competitive position and may materially harm our business, financial
condition and results of operations. Costly and time-consuming litigation could be necessary to enforce and determine the

69

Table of Contents

scope  of  our  proprietary  rights,  and  failure  to  maintain  trade  secret  protection  could  adversely  affect  our  competitive
business position. In addition, others may independently discover or develop our trade secrets and proprietary information,
and the existence of our own trade secrets affords no protection against such independent discovery. For example, a public
presentation  in  the  scientific  or  popular  press  on  the  properties  of  our  product  candidates  could  motivate  a  third  party,
despite any perceived difficulty, to assemble a team of scientists having backgrounds similar to those of our employees to
attempt to independently reverse engineer or otherwise duplicate our antibody technologies to replicate our success.

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

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

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

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

Intellectual property rights do not necessarily address all potential threats.

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

·

·

·

·

·

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;

70

Table of Contents

·

·

·

·

·

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 and any future product candidates we develop. If these third parties do not successfully carry out their
contractual  duties,  comply  with  regulatory  requirements  or  meet  expected  deadlines,  we  may  not  be  able  to  obtain
marketing  approval  for  or  commercialize  NC318,  NC410  and  any  future  product  candidates  we  develop,  and  our
business could be materially harmed.

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

Many  of  the  third  parties  with  whom  we  contract  may  also  have  relationships  with  other  commercial  entities,
including our competitors, for whom they may also be conducting clinical trials or other drug development activities that
could  harm  our  competitive  position.  Further,  under  certain  circumstances,  these  third  parties  may  terminate  their
agreements with us upon as little as 10 days’ prior written notice. Some of these agreements may also be terminated by
such third parties under certain other circumstances. If the third parties conducting our preclinical studies or our clinical
trials  do  not  adequately  perform  their  contractual  duties  or  obligations,  experience  significant  business  challenges,
disruptions or failures, including as a result of natural disasters or public health emergencies such as the 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;

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.

72

Table of Contents

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

Risks Related to Our Business

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

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

We continue to work with Dr. Chen on discovering novel immunomedicines through his consulting agreement and

the SRA with Yale. If we are no longer able to leverage our relationships with Dr. Chen and Yale, our ability to

73

Table of Contents

discover  additional  targets  for  immunomedicines  may  be  impeded,  which  may  adversely  impact  the  achievement  of  our
objectives.

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

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

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

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

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

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

Our  commercial  opportunity  could  be  reduced  or  eliminated  if  our  competitors  develop  and  commercialize

products that are safer, more effective, have fewer or less severe side effects, are more convenient, have a broader label,

74

Table of Contents

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

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

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

·

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

· managing  our  internal  development  efforts  effectively,  including  the  clinical  and  FDA  review  process  for
NC318,  NC410  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 and any future product candidates we develop will depend, in part, on our ability to effectively manage any
future growth, and our management may have to divert a disproportionate amount of its attention away from day-to-day
activities in order to devote a substantial amount of time to managing these growth activities.

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

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

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

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

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

·

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

75

Table of Contents

·

·

·

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;

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

76

Table of Contents

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, 2019, we had federal
and  state  net  operating  loss  carryforwards  of  $55.0  million  and  $54.0  million,  respectively.  The  federal  and  state  net
operating  loss  carryforwards  will  begin  to  expire,  if  not  utilized,  by  2036.  Limitations  imposed  by  the  applicable
jurisdictions  on  our  ability  to  utilize  net  operating  loss  carryforwards  could  cause  income  taxes  to  be  paid  earlier  than
would be paid if such limitations were not in effect and could cause such net operating loss carryforwards to expire unused,
in each case reducing or eliminating the benefit of such net operating loss carryforwards. Furthermore, we may not be able
to  generate  sufficient  taxable  income  to  utilize  our  net  operating  loss  carryforwards  before  they  expire.  If  any  of  these
events occur, we may not derive some or all of the expected benefits from our net operating loss carryforwards. In addition,
we may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, 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.

Global health concerns, including the novel coronavirus outbreak, could impact our business.

Beginning in December 2019, a novel strain of coronavirus was reported in China and other countries, including
the  United  States.  Global  health  concerns,  such  as  coronavirus,  could  result  in  social,  political,  economic  and  labor
instability in the countries in which we or the third parties with whom we engage operate. We cannot presently predict the
scope and severity of any potential business shutdowns or disruptions, but if we 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  were  to  experience  shutdowns  or  other  business
disruptions, our ability to conduct our business in the manner and on the timelines presently planned could be materially
and negatively impacted. It is also possible that global health concerns such as this one could disproportionately impact the
hospitals  and  clinical  sites,  as  well  as  recruitment  and  retention  for  clinical  trials,  in  a  region  or  city  whose  health  care
system becomes overwhelmed due to the illness or where restrictions are put in place on the movement of people or goods.
The extent to which the coronavirus impacts our business will depend on future developments, which are highly uncertain
and cannot be predicted, including new information that may emerge concerning the severity of the coronavirus outbreak
and  the  actions  to  contain  the  coronavirus  and  to  address  its  impact,  including  on  financial  markets  or  otherwise.  The
occurrence of any of these developments and any disruption related to coronavirus could have a material adverse effect on
our business and our results of operation and financial condition.

Risks Related to Our Common Stock

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

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

77

Table of Contents

The price of our common stock may be volatile and fluctuate substantially.

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

our cash position;

78

Table of Contents

·

·

·

·

·

·

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.

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. As of December 31, 2019, we had outstanding a total
of 27,499,260 shares of common stock.

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

In addition, the holders of certain shares of our common stock outstanding as of December  31, 2019 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 by these stockholders could have a material adverse effect on
the market price of our common stock.

79

Table of Contents

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

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

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

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

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

·

·

·

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

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

80

Table of Contents

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

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

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

We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control
over financial reporting in the future. Our independent registered public accounting firm will not be required to provide an
attestation report on the effectiveness of our internal control over financial reporting so long as we qualify as an “emerging
growth company,” which may increase the risk that material weaknesses or significant deficiencies in our internal control
over  financial  reporting  go  undetected.  Any  failure  to  maintain  internal  control  over  financial  reporting  could  severely
inhibit  our  ability  to  accurately  report  our  financial  condition,  results  of  operations  or  cash  flows.  If  we  are  unable  to
conclude that our internal control over financial reporting is effective, or if our independent registered public accounting
firm  determines  we  have  a  material  weakness  or  significant  deficiency  in  our  internal  control  over  financial  reporting,
investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our common
stock  could  decline,  and  we  could  be  subject  to  sanctions  or  investigations  by  Nasdaq,  the  SEC  or  other  regulatory
authorities.  Failure  to  remedy  any  material  weakness  in  our  internal  control  over  financial  reporting,  or  to  implement  or
maintain other effective control systems required of public companies, could also restrict our future access to the capital
markets.

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

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

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

As a public company, and particularly after we are no longer an emerging growth company, we have incurred and
expect to continue to incur significant legal, accounting, investor relations and other expenses that we did not incur as a
private company.  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

81

Table of Contents

their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by
regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs
necessitated by ongoing revisions to disclosure and governance practices.

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

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

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

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

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 we expect the landlord to deliver in April 2020. The New Lease expires in March 2030 and
will also cover the Current Space upon expiration of the Original Lease. We believe that these facilities are adequate for our
current needs and that suitable additional or substitute space will be available in the future if needed.

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 11, 2020 we had 21 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, 2019, $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 6. Selected Financial Data

As a smaller reporting company, we are not required to provide the information requested by this Item.

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

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.

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 was presented at the Society for Immunotherapy of Cancer annual meeting
in  November  2019.  We  began  enrolling  patients  in  the  Phase  2  portion  of  the  trial  in  October  2019  and  expect  to
announce initial data from the Phase 2 portion by the end of 2020. We intend to initiate an additional Phase 2 clinical trial
to  evaluate  NC318  in  combination  with  standard  of  care  chemotherapies  in  patients  with  advanced  or  metastatic
solid tumors in mid-2020. Our second product candidate, NC410, is a novel immunomedicine designed to block immune
suppression  mediated  by  an  immune  modulator  called  Leukocyte-Associated  Immunoglobulin-like  Receptor  1.  The  U.S.
Food and Drug Administration, or the FDA, accepted our investigational new drug application, or IND, for NC410 in the
first quarter of 2020 and we intend to initiate a Phase 1/2 clinical trial in patients with advanced or metastatic solid tumors
in the second quarter of 2020.

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,  2019  and  2018  were  $33.7  million  and  $22.8  million,  respectively.  As
of  December  31,  2019,  we  had  an  accumulated  deficit  of  $81.0  million  primarily  as  a  result  of  research  and
development and general and administrative expenses. We do not expect to generate product revenue unless and until we
obtain  marketing  approval  for  and  commercialize  a  product  candidate,  and  we  cannot  assure  you  that  we  will  ever
generate significant revenue or profits.

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

In November 2018, we entered into 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

84

Table of Contents

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.

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, 2019, we had cash,  cash equivalents and marketable securities, excluding restricted cash, of
$334.6 million. We believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our
planned operations into the first 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 trial and
planned Phase 2 clinical trial of NC318, our planned Phase 1/2 clinical trial of NC410 and other research and development
activities.  We  expect  to  incur  significantly  increased  costs  as  a  result  of  operating  as  a  public  company,  including
significant legal, accounting, investor relations and other expenses that we did not incur as a private company.

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

Components of Our Results of Operations

Revenue

For  the  year  ended  December  31,  2019,  we  recognized  $6.3  million  in  revenue  under  the  Lilly  Agreement.
Through December 31, 2019, we have not generated any revenue from product sales. Through December 31, 2018, we had
not  generated  any  revenue  from  product  sales  or  otherwise.  For  additional  information  about  our  revenue  recognition
policy, see Note 2 to our audited financial statements included elsewhere in this 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;

85

Table of Contents

·

·

·

·

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;

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.

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

Research  and  development  activities  are  central  to  our  business  model.  We  expect  that  our  research  and
development  expenses  will  continue  to  increase  substantially  for  the  foreseeable  future  as  we  advance  our  product
candidates through development, including conducting our ongoing Phase 1/2 clinical trial of NC318, our planned Phase 2
clinical trial in combination with standard of care chemotherapies and preclinical studies and a Phase 1/2 clinical trial of
NC410,  as  we  develop  a  complementary  diagnostic  for  NC318  if  we  determine  it  is  advisable,  and  as  we  expand  our
current  good  manufacturing  practice,  or  cGMP,  manufacturing  capacity,  including  to  provide  drug  supply  of  NC318  for
future clinical trials, and as we expand our pipeline through research and development activities related to our FIND-IO
platform and discovery programs.

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

·

·

·

·

·

·

the scope, progress, results and costs of clinical trials of NC318 and NC410, as well as of any future clinical
trials of other product candidates and other research and development activities that we may conduct;

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.

86

Table of Contents

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 as
a  result  of  staff  expansion  and  additional  occupancy  costs,  as  well  as  costs  associated  with  being  a  public  company,
including higher legal and accounting fees, investor relations costs, higher insurance premiums and other compliance costs
associated with being a public company.

Other Income, Net

Other  income,  net  consists  primarily  of  interest  income  earned  on  U.S.  Treasury  obligations  and  payment  of

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

Revenue from Research and Development Arrangement

Revenue  was  $6.3  million  and  $0  for  the  years  ended  December  31,  2019  and  2018,  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. We expect to record as revenue the
remaining deferred revenue balance of $22.4 million at December 31, 2019 in the first quarter of 2020 as a result of the
termination of the Lilly Agreement in March 2020.

Research and Development Expenses

Research and development expenses for the year ended December  31, 2019 increased by $14.4 million to $34.2

million compared to $19.8 million for the year ended December  31, 2018. The increase was driven primarily by $4.4

million increase in lab supplies and services for NC318, NC410, other early-stage programs and discovery activities. Other
significant  components  of  the  increase  in  research  and  development  expenses  included  $4.1  million  in  personnel-related
costs  due  to  an  increase  in  headcount,  $3.0  million  in  clinical  research  costs  related  to  advancing  NC318,    $0.7  million
payments  pursuant  to  the  SRA  and  other  sponsored  research  agreements  and  $0.6  million  in  research  and  development
license costs.

General and Administrative Expenses

General  and  administrative  expenses  for  the  year  ended  December    31,  2019  increased  by  $6.2  million  to
$9.6 million as compared to $3.4 million for the year ended December  31, 2018. The increase was driven primarily by
increases,  largely  in  connection  with  our  IPO  and  operating  as  a  public  company,  of    $2.8  million  for  professional  fees
related to legal, finance and audit services, public relations, compensation and investor relations support, $1.2 million in
insurance expenses and $0.7 million in personnel-related costs due to an increase in headcount.

Other Income, Net

Other  income,  net  for  the  year  ended  December  31,  2019  increased  by  $3.3  million  to  $3.7  million  from  $0.4
million for the year ended December 31, 2018. The increase was driven primarily by interest income earned on higher cash
and marketable securities balances, partially offset by interest expense related to an increase in the outstanding principal
balance of our term loan from $1.0 million to $5.0 million in January 2019.

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.  Since
inception,  we  have  received  aggregate  gross  proceeds  of  $164.4  million  from  the  sale  and  issuance  of  shares  of  our
preferred  stock.  In  addition,  in  November  2018,  we  received  an  upfront  payment  of  $25.0  million  in  cash  from  Lilly
pursuant to the Lilly Agreement. Our cash and cash equivalents are held in money market funds.

As of December 31, 2019, we had cash, cash equivalents and marketable securities, excluding restricted cash, of
$334.6 million. We believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our
planned operations into the first 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 will make interest-only payments through January 2020 and 36 equal
monthly  payments  of  principal  plus  accrued  interest  thereafter  through  January  2023.  As  of  December  31,  2019,  our
outstanding borrowings under this term loan were $5.0 million.

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

88

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 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  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  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

the  costs  involved  in  preparing,  filing,  prosecuting,  maintaining,  expanding,  defending  and  enforcing
patent claims, including litigation costs and the outcome of any such litigation;

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

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

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

Adequate  additional  financing  may  not  be  available  to  us  on  acceptable  terms,  or  at  all.  If  we  raise  additional
funds  by  issuing  equity  securities,  our  stockholders  may  experience  dilution.  Any  future  debt  financing  into  which  we
enter  may  impose  upon  us  additional  covenants  that  restrict  our  operations,  including  limitations  on  our  ability  to  incur
liens  or  additional  debt,  pay  dividends,  repurchase  our  common  stock,  make  certain  investments  and  engage  in  certain
merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms
that  are  not  favorable  to  us  or  our  stockholders.  If  we  raise  additional  funds  through  government  or  private  grants,
collaborations,  strategic  alliances  or  marketing,  distribution  or  licensing  arrangements  with  third  parties,  we  may  be
required to    relinquish valuable rights to our future revenue streams, product candidates or research programs or to grant
licenses  on  terms  that  may  not  be  favorable  to  us.  If  we  are  unable  to  raise  additional  funds  when  needed,  we  may  be
required to delay, reduce or terminate some or all of our development programs and clinical trials. We may also be required
to sell or license to others rights to our product candidates in certain territories or indications that we would prefer to retain
for  ourselves.  See  the  section  entitled  "Risk  Factors"  for  additional  risks  associated  with  our  substantial  capital
requirements.

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

Cash Used in Investing Activities

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 investing activities for the year ended December 31, 2018 was
$3.1 million, which consisted primarily of purchases of laboratory equipment.

Cash Provided by Financing Activities

Cash provided by financing activities was $243.0 million for the year ended December 31, 2019, which consisted
primarily of net proceeds from the Company’s public offering. Cash provided by financing activities was $121.4 million for
the year ended December 31, 2018, which consisted of gross proceeds from the sale and issuance of shares of our Series A
and B Preferred Stock, partially offset by issuance costs, deferred offering costs and payments under the Term Loan.

We had operating lease obligations consisting of two operating leases for our corporate headquarters for a total of
approximately  50,000  square  feet  as  of  December  31,  2019.  The  terms  of  the  leases  expire  in  August  2025  and  March
2030. Under the terms of the leases, we will have lease obligations aggregating $8.8 million through 2025.

The contractual obligations table does not include any potential contingent payments upon the achievement by us
of clinical, regulatory and commercial events, as applicable, or royalty payments that we may be required to make under
license agreements we have entered into with various entities pursuant to which we have in-licensed intellectual  property,
including, our license agreement with Yale and the SRA with Yale. We excluded the contingent payments given that the

timing  and  amount  (if  any)  of  any  such  payments  cannot  be  reasonably  estimated  at  this  time.  See  “Business—Our
Collaboration Agreements” for additional information.

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

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  the  underlying  assumptions  used  in  revenue  recognition  and  valuing  share-based  compensation,
including  the  fair  value  of  our  common  stock  in  periods  before  our  IPO.  Our  estimates  are  based  on  our  historical
experience and on various other factors that we believe are reasonable under the circumstances, the results of which form
the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other
sources. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from these estimates
under different assumptions or conditions.

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,  see  Note  2  to  our
audited financial statements included elsewhere in this Annual Report.

Revenue Recognition

We  account  for  revenue  in  accordance  with  ASC  Topic  606,  Revenue  from  Contracts  with  Customers  (“ASC
606”). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services in an
amount  that  reflects  the  consideration  that  the  entity  expects  to  receive  in  exchange  for  those  goods  or  services.  To
determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of ASC
606,  we  perform  the  following  five  steps:  (i)  identification  of  the  promised  goods  or  services  in  the  contract;  (ii)
determination of whether the promised goods or services are performance obligations, including whether they are distinct
in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration;
(iv)  allocation  of  the  transaction  price  to  the  performance  obligations;  and  (v)  recognition  of  revenue  when  (or  as)  we
satisfy each performance obligation. We only apply the five-step model to contracts when it is probable that we will collect
consideration  to  which  we  are  entitled  in  exchange  for  the  goods  or  services  we  transfer  to  the  customer.  For  further
discussion of revenue recognition, see Note 2 to our audited financial statements included elsewhere in this Annual Report.

Stock‑Based Compensation

We  account  for  stock‑based  compensation,  including  stock  options  and  restricted  stock  units,  based  on  the  fair
value of the award as of the grant date. We utilize the Black‑Scholes option‑pricing model as the method for estimating the
fair  value  of  our  stock  option  grants.  The  Black‑Scholes  option‑pricing  model  requires  the  use  of  highly  subjective  and
complex assumptions, including the options’ expected term and the price volatility of the underlying stock. The fair value
of the portion of the award that is ultimately expected to vest is recognized as compensation expense over the award’s

91

Table of Contents

requisite service period. We recognize stock‑based compensation to expense using the straight‑line method. If there are any
modifications or cancelations of stock‑based awards, we may be required to accelerate, increase or decrease any remaining
unrecognized stock‑based compensation expense.

Stock‑based  compensation  expense,  net  of  estimated  forfeitures,  is  reflected  in  the  statements  of  operations  and

comprehensive loss as follows:

As of December 31, 2019, total unamortized stock‑based compensation was $6.9 million.

The intrinsic value of all outstanding stock options as of December 31, 2019 was $113.3 million.  

Common Stock Valuation

Before  our  IPO,  there  was  no  public  market  for  our  common  stock  to  date  and  the  estimated  fair  value  of  our
common stock was determined by our board of directors as of the date of each option grant, with input from management,
considering our most recently available third-party valuations of common stock, and our board of directors’ assessment of
additional objective and subjective factors that it believed were relevant and which may have changed from the date of the
most recent valuation through the date of the grant. These third-party valuations were performed in accordance with the
guidance outlined in the American Institute of Certified Public Accountants.

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

Since the closing of our IPO, our board of directors has determined the fair value of our common stock based on

the closing price of our common stock on the Nasdaq Global Select Market as reported on the date of grant.

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

statements included elsewhere in this Annual Report.

Off‑Balance Sheet Arrangements

Since  our  inception,  we  have  not  engaged  in  any  off‑balance  sheet  arrangements,  as  defined  in  the  rules  and

regulations of the Securities and Exchange Commission.

JOBS Act Accounting Election

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

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on the Financial Statements

We have audited the accompanying balance sheets of NextCure, Inc. (the “Company”) as of December 31, 2019
and 2018, 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, 2019 and 2018, 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

immune  function.  Through 

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 
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.

its  proprietary  Functional,  Integrated,  NextCure  Discovery 

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,  on  May  13,  2019,  all  of  the  outstanding  shares  of  the  Company’s  convertible
preferred stock automatically converted into 15,560,569 shares of common stock at the applicable conversion ratio then in
effect. Subsequent to the closing of the IPO, there were no shares of preferred stock outstanding.

Upon  the  closing  of  the  IPO,  on  May  13,  2019,  the  Company’s  certificate  of  incorporation  was  amended  and
restated  to  provide  for  100,000,000  authorized  shares  of  common  stock  with  a  par  value  of  $0.001  per  share  and
10,000,000 authorized shares of preferred stock with a par value of $0.001 per share.

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  2019,  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, 2019, the Company expects that its cash
and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements through

100

Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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.

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.

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

101

 
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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, 2019 and 2018, the Company had restricted cash of $5.0 million and $460,000, 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  $5.0  million  and
$480,000 as of December 31, 2019 and December 31, 2018, 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:

Marketable Securities

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. Investment income is recognized when earned and reported net of investment expenses. Unrealized holding gains
and losses are reported within accumulated other comprehensive income (loss) as a separate component of stockholders’
equity.  The  amortized  cost  of  debt  securities  is  adjusted  for  amortization  of  premiums  and  accretion  of  discounts  to
maturity. Such amortization and interest on securities are included in other income, net, on the Company’s statements of
operations.

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

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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.

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

Fair Value of Financial Instruments

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

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

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

103

 
 
 
 
 
 
    
 
 
 
 
 
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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,
2019 or 2018.

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  is  classified  outside  of  stockholders’  deficit  for  the  period  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.

Research and Development Costs, Including Clinical Trial Accruals

Research costs consist of employee-related costs, contractor expenses, laboratory supplies and facility costs, for
research  and  development  of  product  candidates  are  expensed  as  incurred.  Development  costs,  including  clinical  trial-
related expenses, incurred by third parties,  such as clinical research organizations (CROs), are expensed as the contracted
work  is  performed.  Where  contingent  milestone  payments  are  due  to  third  parties  under  research  and  development
arrangements, the milestone payment obligations are expensed when the milestone results are probable of being achieved.
When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies, including the phase
or completion of events, invoices received and contracted costs.

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

104

 
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

differ from the estimates made. The historical clinical accrual estimates have not been materially different from the actual
costs.

Patent Costs

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

Stock‑Based Compensation

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

The Black‑Scholes option pricing model requires inputs based on certain subjective assumptions, including (i) the
expected  stock  price  volatility,  (ii)  the  expected  term  of  the  award,  (iii)  the  risk‑free  interest  rate  and  (iv)  expected
dividends. Due to the lack of a public market for the Company’s common stock and lack of company‑specific historical and
implied  volatility  data,  the  Company  has  based  its  computation  of  expected  volatility  on  the  historical  volatility  of  a
representative  group  of  public  companies  with  similar  characteristics  to  the  Company,  including  stage  of  product
development and life science industry focus. The historical volatility is calculated based on a period of time commensurate
with  expected  term  assumption.  The  Company  uses  the  simplified  method  as  prescribed  by  the  SEC  Staff  Accounting
Bulletin No. 107, Share‑Based Payment, to calculate the expected term for options granted to employees as it does not have
sufficient  historical  exercise  data  to  provide  a  reasonable  basis  upon  which  to  estimate  the  expected  term.  The  expected
term is applied to the stock option grant group as a whole, as the Company does not expect substantially different exercise
or post‑vesting termination behavior among its employee population. For options granted to non‑employees, the Company
utilizes the simplified method also as the basis for the expected term assumption. The risk‑free interest rate is based on a
treasury instrument whose term is consistent with the expected term of the stock options. The expected dividend yield is
assumed to be zero because the Company has never paid dividends and has no current plans to pay any dividends on its
common  stock.  The  Company  recognizes  forfeitures  as  they  occur  as  allowed  by  ASU  No.  2016‑09,  Improvements  to
Employee Share‑Based Payment Accounting (“ASU 2016‑09”).

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

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

requisite service period, which is generally the vesting period.

Income Taxes

The  Company  uses  the  asset  and  liability  method  of  accounting  for  income  taxes.  Deferred  tax  assets  and
liabilities  are  recognized  for  the  estimated  future  tax  consequences  attributable  to  temporary  differences  between  the
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    deferred  revenue  and  its  net  operating  loss
carryforwards,  are  measured  using  enacted  tax  rates  expected  to  apply  to  taxable  income  in  the  years  in  which  those
temporary differences are expected to be recovered or settled. Deferred tax expense or benefit is the result of changes in the
deferred tax assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets where,
based upon the available evidence, the Company concludes that it is more‑likely‑than‑not that the deferred tax assets will
not be realized. In evaluating its ability to recover deferred tax assets, the Company considers all available

105

 
Table of Contents

NOTES TO FINANCIAL STATEMENTS

positive and negative evidence, including its operating results, ongoing tax planning and forecasts of future taxable income
on a jurisdiction‑by‑jurisdiction basis. Because of the uncertainty of the realization of deferred tax assets, the Company has
recorded a full valuation allowance against its deferred tax assets.

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

Revenue Recognition

The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers
(“ASC  606”).  Under  ASC  606,  an  entity  recognizes  revenue  when  its  customer  obtains  control  of  promised  goods  or
services  in  an  amount  that  reflects  the  consideration  that  the  entity  expects  to  receive  in  exchange  for  those  goods  or
services. To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the
scope of ASC 606, the Company performs the following five steps: (i) identification of the promised goods or services in
the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether
they  are  distinct  in  the  context  of  the  contract;  (iii)  measurement  of  the  transaction  price,  including  the  constraint  on
variable  consideration;  (iv)  allocation  of  the  transaction  price  to  the  performance  obligations;  and  (v)  recognition  of
revenue when (or as) the Company satisfies each performance obligation. The Company only applies the five-step model to
contracts when it is probable that the Company will collect consideration to which it is entitled in exchange for the goods or
services it transfers to the customer.

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

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

The  Company  estimates  the  transaction  price  based  on  the  amount  expected  to  be  received  for  transferring
the    goods  or  services  promised  in  the  contract.  Consideration  generally  may  include  fixed  consideration  or  variable
consideration. Should an arrangement include variable consideration, the Company will evaluate the amount of potential
payments and the likelihood that the payments will be received. The Company will utilize either the most likely amount
method or expected amount method to estimate the amount expected to be received based on which method best predicts
the amount expected to be received. The amount of variable consideration that is included in the transaction price may be
constrained and will be included in the transaction price only to the extent that it is probable that a significant reversal in
the amount of the cumulative revenue recognized will not occur in a future period.

The Company’s contracts may include development and regulatory milestone payments, which would be assessed
under  the  most  likely  amount  method  and  constrained  if  it  is  probable  that  a  significant  revenue  reversal  would  occur.
Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, will
not be considered probable of being achieved until those approvals are received. At the end of each reporting period, the
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

106

 
Table of Contents

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

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, 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.

During  the  year  ended  December  31,  2018,  the  Company  calculated  basic  and  diluted  net  loss  per  share
attributable  to  common  stockholders  in  conformity  with  the  two‑class  method  required  for  participating  securities.  The
Company considered its Series A Preferred Stock and Series B Preferred Stock to be participating securities because in the
event a dividend was paid on common stock, the holders of Series A Preferred Stock and Series B Preferred Stock were
entitled to receive dividends on a basis consistent with the common stockholders. Under the two‑class method, the net loss
attributable to common stockholders is not allocated to the preferred stock as the holders of the preferred stock do not have
a  contractual  obligation  to  share  in  losses.  Under  the  two‑class  method,  basic  net  loss  per  share  attributable  to  common
stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of
shares of common stock.

Recently Issued Accounting Pronouncements

The Company qualifies as an emerging growth company (“EGC”) as defined under the Jumpstart Our Business
Startups  Act  (the  “JOBS  Act”).  Using  exemptions  provided  under  the  JOBS  Act  provided  to  EGCs,  the  Company  has
elected  to  defer  compliance  with  new  or  revised  financial  accounting  standards  until  it  is  required  to  comply  with  such
standards.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). The new guidance will require
lessees  to  record  most  leases  on  their  balance  sheets  and  recognize  the  related  expenses  on  their  income  statements  in  a
manner similar to current practice. ASU 2016-02 states that a lessee would recognize a lease liability for the obligation to
make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The standard is
effective  for  the  Company  January  1,  2021.  The  Company  continues  to  determine  if  it  will  elect  to  use  the  practical
expedients  permitted  by  the  guidance  and  continues  to  gather  data  required  to  comply  with  the  guidance.  Based  on  the
work completed to date, the Company is considering the implications of adopting the new standard, including the discount
rate to be used in valuing new and existing leases and all applicable financial statement disclosures required by the new
guidance. The Company is continuing to evaluate the effect of adoption and anticipates that it will result in the recognition
of  additional  assets  and  corresponding  liabilities  related  to  the  existing  leases  on  its  balance  sheet.  The  Company  is
assessing  any  potential  impacts  on  its  internal  controls,  business  processes,  and  accounting  policies  related  to  both  the
implementation of, and ongoing compliance with, the new guidance.

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 non-emerging growth companies for fiscal years beginning December 15, 2019 and interim periods within those fiscal
years, and will be effective for the Company for fiscal years beginning after December 15, 2020, and interim periods within
fiscal  years  beginning  after  December  15,  2021,  assuming  the  Company  remains  an  emerging  growth  company.  Early
adoption  is  permitted.  The  Company  is  currently  evaluating  the  effects  the  adoption  of  ASU  2016-13  will  have  on  its
financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement—Disclosure Framework-Changes
to the Disclosure Requirement for Fair Value Measurement (“ASU 2018-13”). The amendments in ASU 2018-13 modify
the disclosure requirements on fair value measurements in ASC Topic 820, Fair Value Measurement, based on the concepts
in the FASB Concepts Statement, including the consideration of costs and benefits. ASU 2018-13 will be effective for all
companies  for  fiscal  periods  beginning  after  December  15,  2019  and  interim  periods  within  those  fiscal  years.  Early
adoption  is  permitted.  The  Company  is  currently  evaluating  the  effects  the  adoption  of  ASU  2018-13  will  have  on  its
financial statements.

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. Under the Lilly Agreement, Lilly and the Company granted one another an equal number of exclusive
options  to  research,  develop,  manufacture  and  commercialize  compounds  and  products  directed  to  oncology  targets
identified through the Lilly Agreement. 

During the research term under the Lilly Agreement, as a part of target discovery, the Company was responsible
for providing Lilly with oncology targets identified using the Company’s FIND-IO platform. From the targets provided by
the Company, Lilly could select targets to advance to target validation using criteria developed by both parties. Following
completion of the agreed upon target validation plan with respect to a given target, either party could propose to advance
that  target  to  compound  discovery.  For  each  target  advanced  to  compound  discovery,  Lilly  had  the  option  to  obtain  an
exclusive license with respect to the compounds and products directed to the target. If Lilly did not exercise its option with
respect to a given target or has previously exercised all of its options, the Company had the option to obtain licenses with
respect to compounds and products directed to that target.

NEXTCURE, INC.
NOTES TO FINANCIAL STATEMENTS

In  November  2018,  the  Company  received  an  upfront,  non-refundable  payment  of  $25.0  million  under  the
Lilly Agreement and a concurrent $15.0 million equity investment (Note 10). In addition, Lilly agreed to make quarterly
research and development support payments during a portion of the research term as well as to pay option exercise fees
upon option exercises by Lilly. 

Pursuant  to  the  Lilly  Agreement,  Lilly  agreed  to  pay  an  aggregate  of  up  to  $1.4  billion  in  development  and
regulatory milestones and sales milestones. Additionally, Lilly agreed to pay mid to high single-digit royalties on net sales
for  all  products  directed  to  each  target  optioned  by  Lilly.  The  Company  agreed  that  upon  the  Company’s  exercise  of  an
option with respect to a given target, the Company would pay Lilly option exercise payments and also agreed to pay an
aggregate of up to $710.0 million in development and regulatory milestones and sales milestones, as well as royalties.

The  Company  evaluated  the  Lilly  Agreement  under  the  provisions  of  ASC  606  and  concluded  that  Lilly  was  a
customer  prior  to  the  exercise  of  its  option  to  obtain  an  exclusive  license  with  respect  to  the  compounds  and  products
directed to a target advanced to compound discovery. The Company identified the following material promises under the
Lilly  Agreement:  (i)  a  limited  research  license  to  conduct  activities  under  the  research  collaboration;  (ii)  research  and
development  services  together  with  the  provision  of  a  data  package  in  connection  with  Lilly’s  option;  (iii)  various
governance obligations, most notably participation on a joint steering committee; and (iv) rights related to an optional term
extension by Lilly. The Company evaluated Lilly’s option to obtain an exclusive license with respect to the compounds and
products directed to a target that has been advanced to compound discovery and concluded that the option was not issued at
a  significant  and  incremental  discount,  and  therefore  does  not  provide  material  rights.  As  such,  they  are  excluded  as
performance  obligations  at  the  outset  of  the  arrangement.  The  Company  determined  that  the  research  license  was  not
capable of being distinct and the related research and development services and governance activities are not distinct in the
context  of  the  contract  and,  as  such,  the  Company  determined  that  these  promises  should  be  combined  into  a  single
performance obligation, resulting in a total of two performance obligations under the Lilly Agreement; one for research and
development services and one for the right related to an optional term extension by Lilly.

The  transaction  price  at  the  outset  of  the  arrangement  was  determined  to  be  $32.7  million,  comprised  of  the
upfront fee received from Lilly, quarterly research and development support payments to be received from Lilly during a
portion  of  the  research  term  and  an  equity  investment  premium  as  determined  by  the  Company  with  reference  to  a
valuation  of  the  Company’s  preferred  stock  prepared  by  an  unrelated  third-party  valuation  firm  in  accordance  with  the
guidance provided by the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-
Company Equity Securities Issued as Compensation.

The  transaction  price  was  allocated  to  the  two  performance  obligations  based  on  their  relative  standalone
selling price determined with reference to the Company’s estimated costs attendant to the obligations. Revenue allocated to
the  research  and  development  performance  obligation  was  recognized  as  the  research  and  development  services  were
provided using an input method calculated by comparing research and development costs incurred to date to estimated total
research and development costs as a measure of progress towards satisfying the performance obligation. Revenue allocated
to  Lilly’s  right  related  to  an  optional  term  extension  was  deferred  until  the  right  was  exercised  or  lapsed,  and  will
subsequently be recognized accordingly. 

While the Lilly Agreement was executed in November 2018, the performance initiated in January 2019. Under the
Lilly  Agreement,  the  Company  recognized  revenue  of  $6.3  million  and  $0  for  the  years  ended  December  31,  2019  and
2018, respectively.

8. Commitments and Contingencies

Operating Leases

On  February  9,  2016,  the  Company  entered  into  a  non-cancelable  facilities  operating  sublease  (the  “2016
Sublease”). On March 15, 2019, the Company amended and restated the 2016 Sublease (as amended, the “Amended 2016
Sublease”) to include additional square footage to be used for office space, which the Company took possession of upon
entering into the Amended 2016 Sublease. The Amended 2016 Sublease expires in August 2025. The base rent under the
Amended 2016 Sublease is currently $32,254 per month plus the Company’s prorated share of the sublandlord’s operating
expense and is subject to annual rent increases of 3%.  

On January 30, 2019, the Company entered into a new lease to be used for office and laboratory space (the “New
Premises”), which the Company took possession of on June 1, 2019 (the “2019 Lease”). On August 2, 2019, the Company
amended the 2019 Lease (as, the “Amended 2019 Lease”) to include additional space to be used for office and laboratory
space (the “Expansion Premises”), which the Company expects to take possession of on April 1, 2020. The Amended 2019
Lease expires in March 2030. Upon expiration of the Amended 2016 Sublease, the Amended 2019 Lease will also cover
the space the Company is currently subleasing under the Amended 2016 Sublease. Base rent is abated until April 1, 2020
for the New Premises and until seven months after delivery of the Expansion Premises for the Expansion Premises, after
which the base rent will be $19,646 per month for the New Premises and $18,178 per month for the Expansion Premises,
each subject to annual rent increases of 3%. In connection with this lease, the Company executed a $39,000 letter of credit,
which  has  not  been  drawn  down  on.  Additionally,  there  is  a  base  rate  adjustment  of  8.5%  per  annum  multiplied  by  the
outstanding  balance  of  amounts  paid  for  tenant  improvements.  The  budgeted  amounts  of  tenant  improvements  are
approximately  $1,477,000  for  the  New  Premises  and  $1,517,000  for  the  Expansion  Premises,  which  are  to  be  fully
reimbursed by the landlord.

At  December  31,  2019,  the  Company’s  minimum  obligations  under  non-cancelable  operating  leases  are  as

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. As of December 31, 2019, and
2018, the Company was not involved in any material legal proceedings.

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 4.40% and 3.95% for the years ended December 31, 2019 and 2018, respectively. Under the Term Loan,
the Company is required to make monthly interest-only payments through January 2020 and is required to make 36 equal
monthly  payments  of  principal  plus  accrued  interest  thereafter  through  January  2023.  The  Term  Loan  is  secured  by  all
certificates of deposit, money market accounts, cash, securities, investment property and deposit or investment accounts.
Interest expense under the Term Loan was approximately $209,000 and $25,000 for the years ended December 31, 2019
and 2018, respectively. The outstanding balance on the Term Loan totaled $5.0 million and $460,000 as of December 31,

Upon  the  closing  of  the  IPO,  on  May  13,  2019,  all  of  the  outstanding  shares  of  the  Company’s  preferred  stock
automatically converted into 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.

The  Company’s  preferred  stock  that  was  outstanding  as  of  December  31,  2018  is  classified  outside  of
stockholders’  equity  (deficit)  because  the  shares  contained  deemed  liquidation  rights  that  were  a  contingent  redemption
feature not solely within the control of the Company.

As  of  December  31,  2019,  the  Company’s  certificate  of  incorporation,  as  amended  and  restated,  authorized  the
Company to issue 10,000,000 shares of $0.001 par value preferred stock, and there were no shares of preferred stock issued
or outstanding. The Company can fix the price, rights, preferences, privileges and restrictions of the preferred stock without
any further vote or action by its stockholders.

11. Common Stock

As of December 31, 2019, 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  27,499,260  were  issued  and

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, 2019, 2,661,566 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 estimated fair value of the common stock for the options that were in the money at December 31, 2019 and 2018.

The  weighted  average  grant  date  fair  value  per  share  of  stock  options  granted  during  the  years  ended
December 31, 2019 and 2018 was $11.92 and $3.80, respectively. The aggregate intrinsic value of stock options exercised
during the years ended December 31, 2019 and 2018 was $7,225,000 and $38,000, respectively.

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

December 31, 2019 and 2018 was approximately $7,637,000 and $157,000, respectively.

The Company’s potential dilutive securities, which as of December 31, 2019 include common stock options, have
been excluded from the computation of diluted net loss per share because the effect would be anti-dilutive. Therefore, the
weighted  average  number  of  common  shares  used  to  calculate  both  basic  and  diluted  net  loss  per  common  share  is  the
same.  The  Company  excluded  2,170,212  and  2,056,891  potential  shares  of  common  stock,  presented  based  on  amounts
outstanding as of December 31, 2019 and 2018, respectively, from the computation of diluted net loss per common share
for the periods indicated because including them would have had an anti-dilutive effect. 

On May 3, 2019, the Company’s stockholders approved the NextCure, Inc. 2019 Employee Stock Purchase Plan
(the  “ESPP”),  which  became  effective  on  the  Effective  Date.  The  ESPP  is  intended  to  qualify  as  an  “employee  stock
purchase plan” within the meaning of Section 423(b) of the Internal Revenue Code. A total of 240,000 shares of common
stock were reserved for issuance under this plan. In addition, the number of shares of common stock that may be issued
under the ESPP will automatically increase on January 1, 2020 and each January 1st thereafter until expiration of the ESPP,
in  an  amount  equal  to  the  lesser  of  (i)  1%  of  the  number  of  shares  of  the  Company’s  common  stock  outstanding  on
December  31st  of  the  preceding  calendar  year,  (ii)  480,000  shares  of  common  stock  and  (iii)  a  number  of  shares  of
common stock determined by the administrator of the ESPP. As of December 31, 2019, no shares of common stock had
been issued pursuant to the ESPP and 240,000 shares were reserved for future issuance thereunder.

Stock‑Based Compensation

The  Company  recorded  stock‑based  compensation  expense  of  $1.9  million  and  $0.3  million  during  the  years
ended  December  31,  2019  and  2018,  respectively.  As  of  December  31,  2019,  there  was  $6.9  million  of  unrecognized
compensation  cost  related  to  unvested  stock‑based  compensation  arrangements  granted  under  the  Plans.  This  remaining

Based on the Company’s history of losses, the Company recorded a full valuation allowance against its deferred
tax assets as of December 31, 2019. The Company increased its valuation allowance by approximately $10.1 million for
the  year  ended  December  31,  2019.  The  Company  intends  to  maintain  a  valuation  allowance  until  sufficient  positive
evidence exists to support a reversal of the allowance.

As of December 31, 2019, the Company had federal and state net operating loss carryforwards of $55.0 million
and  $54.0  million,  respectively,  some  of  which  begin  to  expire  in  the  year  ending  December  31,  2036.  Approximately
$32.3 million of the federal and state net operating loss carryforwards do not expire. The Company had federal and state
research  and  development  tax  credit  carryforwards  of  approximately  $4.1  million  and  $0.1  million,  respectively,  as  of
December 31, 2019. 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 2016
to 2018 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,  2019,  the  Company  had  no  unrecognized  income  tax  benefits  that  would  affect  the  Company’s
effective tax rate if recognized.

On  December  22,  2017,  the  U.S.  government  signed  into  law  the  Tax  Cuts  and  Jobs  Act  (the  “Tax  Act”)  that
significantly reforms the Internal Revenue Code of 1986, as amended. In 2018, the Company finished its analysis of the
impact of the Tax Act. Where the Company made reasonable estimates in 2017 of the effects related to the Tax Act, the

statements did not differ from the recorded provisional amounts.

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. Through December 31, 2019, the Company has not provided any contributions to this plan.

On January 10, 2020, Lilly notified the Company of its termination of the Lilly Agreement (Note 7), effective as
of    March  3,  2020  (the  "Lilly  Termination  Date").    Effective  as  of  the  Lilly  Termination  Date,  both  parties  have  been
relieved of all obligations under the agreement, including future quarterly research and development support payments to
be paid by Lilly to the Company.

As  of  December  31,  2019,  the  Company  had  deferred  revenue  related  to  the  Lilly  Agreement  of  $22.4  million,
which is composed of a non-refundable up-front payment and a premium on the proceeds from Lilly's investment in the
Company. The  Company  will  recognize  all  of  the  deferred  revenue  as  of  the  Lilly  Termination  Date  in  the  statement  of
operations in the first quarter of 2020.

Item 9A. 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,  2019.  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, 2019, 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

There was no change in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f)
under  the  Exchange  Act,  that  occurred  during  the  year  ended  December    31,  2019  that  has  materially  affected,  or  is
reasonably likely to materially affect, our internal control over financial reporting.

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.2

As of the end of the period covered by the Annual Report on Form 10-K of which this exhibit forms a part,  the only class of
securities  of  NextCure,  Inc.  (“we”  and  “our”)  registered  under  Section  12  of  the  Securities  Exchange  Act  of  1934,  as  amended  (the
“Exchange Act”), is our common stock, $0.001 par value per share.

COMMON STOCK

The  following  summary  describes  our  common  stock  and  certain  provisions  of  our  amended  and  restated  certificate  of
incorporation,  our  amended  and  restated  bylaws,  our  amended  and  restated  investors’  rights  agreement  and  the  Delaware  General
Corporation Law. Because the following is only a summary, it does not contain all of the information that may be important to you. For a
complete description, you should refer to our amended and restated certificate of incorporation, our amended and restated bylaws and
our amended and restated investors’ rights agreement, which are incorporated by reference as exhibits to the Annual Report on Form
10-K of which this exhibit is a part, and the applicable provisions of the Delaware General Corporation Law.

General

share.

Our  amended  and  restated  certificate  of  incorporation  authorizes  100,000,000  shares  of  common  stock,  $0.001  par  value  per

Voting Rights

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

Dividends

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled

to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.

Liquidation

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

Other Rights and Preferences

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

1

 
Fully Paid and Nonassessable

All of our outstanding shares of common stock are fully paid and nonassessable.

Preferred Stock

Under  the  terms  of  our  amended  and  restated  certificate  of  incorporation,  our  board  of  directors  has  the  authority,  without
further  action  by  our  stockholders,  to  issue  up  to  10,000,000  shares  of  preferred  stock  in  one  or  more  series  and  to  fix  the  rights,
preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights,
voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting, or the designation
of, such series, any or all of which may be greater than the rights of common stock. For example, the issuance of our preferred stock
could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments
and payments upon our liquidation.

Registration Rights

Under  the  terms  of  our  amended  and  restated  investors’  rights  agreement,  the  holders  of  certain  shares  of  common  stock,  or
their transferees, have the right to require us to register their shares under the Securities Act of 1933, as amended, or the Securities Act,
so that those shares may be publicly resold, and the right to include their shares in any registration statement we file subject to certain
limitations.  These  rights  will  expire,  with  respect  to  any  particular  stockholder,  upon  the  earlier  of  May  13,  2024  and  when  that
stockholder can sell all of its shares under Rule 144 under the Securities Act without limitation during any three-month period without
registration.

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

Bylaws and Delaware Law

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

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

Delaware Anti-Takeover Statute

We  are  subject  to  Section  203  of  the  Delaware  General  Corporation  Law,  which  prohibits  persons  deemed  “interested
stockholders” from engaging in a “business combination” with a publicly traded Delaware corporation for three years following the date
these  persons  become  interested  stockholders  unless  the  business  combination  is,  or  the  transaction  in  which  the  person  became  an
interested  stockholder  was,  approved  in  a  prescribed  manner  or  another  prescribed  exception  applies.  Generally,  an  “interested
stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested
stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or
stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an
anti-takeover  effect  with  respect  to  transactions  not  approved  in  advance  by  our  board  of  directors,  such  as  discouraging  takeover
attempts that might result in a premium over the market price of our common stock.

Undesignated Preferred Stock

The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue preferred stock with
voting or other rights or preferences that could have the effect of delaying, deferring, preventing or otherwise impeding any attempt to
change control of us.

2

Special Stockholder Meetings

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that a special meeting of

stockholders may be called only by or at the direction of our board of directors or by the Chair of our board of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

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

Elimination of Stockholder Action by Written Consent

Our amended and restated certificate of incorporation and our amended and restated bylaws eliminate the right of stockholders

to act by written consent without a meeting.

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

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

Choice of Forum

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

Amendment of Charter Provisions

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

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