Item 1. Business

Overview

PART I

We  are  a  clinical-stage  biopharmaceutical  company  focused  on  developing  novel  drug  candidates  for  immuno-
inflammatory  diseases.    In  addition  to  developing  our  novel  drug  candidates,  we  are  pursuing  strategic  alternatives,
including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our novel drug candidates.

Our Drug Candidates Currently in Development

Our  pipeline  of  drug  candidates  that  we  are  currently  developing  is  summarized  in  the  table  below.  These

investigational drugs were developed internally utilizing our proprietary KINect drug discovery platform.

MK2  Inhibitors,  JAK  Inhibitors  and  ITK  Inhibitors  as  Potential  Treatments  for  Immuno-Inflammatory

Diseases

In  2017,  we  acquired  Confluence  Life  Sciences,  Inc.  (now  known  as  Aclaris  Life  Sciences,  Inc.),  or
Confluence.  The acquisition of Confluence added small molecule drug discovery and preclinical development capabilities,
including KINect, a proprietary drug discovery platform. This allowed us to bring early-stage research and development
activities in-house that we previously outsourced to third parties. We intend to leverage these capabilities and KINect to
identify potential drug candidates that we may develop independently or in collaboration with third parties. As part of the
Confluence  acquisition  we  also  acquired  our  investigational  drug  candidates,  ATI-450,  an  inhibitor  of  the  mitogen-
activated  protein  kinase-activated  protein  kinase  2,  or  MK2,  signaling  pathway,  and  ATI-1777,  a  topical  “soft”  Janus
kinase, or JAK, inhibitor, as well as several other preclinical drug candidates including inhibitors of interleukin-2-

Table of Contents

inducible T cell kinase, or ITK. We also earn revenue from Confluence’s provision of contract research services to third
parties. 

ATI-450, an Investigational Oral MK2 Inhibitor

We  submitted  an  Investigational  New  Drug  Application,  or  IND,  in  April  2019  for  ATI-450,  an  investigational
oral,  novel,  small  molecule  selective  MK2  inhibitor  compound,  for  the  treatment  of  rheumatoid  arthritis,  which  was
allowed by the U.S. Food and Drug Administration, or FDA, in May 2019.  MK2 is a key regulator of pro-inflammatory
mediators  including  TNFα,  IL1β,  IL6,  IL8  and  other  essential  pathogenic  signals  in  chronic  immuno-inflammatory
diseases,  as  well  as  in  oncology.    As  an  oral  drug  candidate,  we  are  developing  ATI-450  as  a  potential  alternative  to
injectable anti-TNF/IL1/IL6 biologics and JAK inhibitors for treating certain immuno-inflammatory diseases.

We initiated a Phase 1 single (at 10mg, 30mg, 50mg and 100mg doses) and multiple ascending (at 10mg, 30mg
and 50mg doses) dose clinical trial evaluating ATI-450 in 77 healthy subjects in August 2019 (ATI-450-PKPD-101). Final
data from this trial demonstrated that ATI-450 resulted in marked inhibition of TNFα, IL1β, IL8 and IL6. We also observed
that ATI-450 had dose-proportional pharmacokinetics with a terminal half-life of 9-12 hours in the multiple ascending dose
cohort,  and  had  no  meaningful  food  effect  or  drug-drug  interaction  with  methotrexate.    ATI-450  was  generally  well-
tolerated at all doses tested in the trial.  The most common adverse events (reported by 2 or more subjects who received
ATI-450) were dizziness, headache, upper respiratory tract infection, constipation, abdominal pain and nausea. 

ATI-450  was  also  evaluated  at  80mg  and  120mg  doses  twice  daily  in  a  second  Phase  1  clinical  trial  in  healthy
subjects  (ATI-450-PKPD-102).  Preliminary  topline  data  from  this  trial  showed  that  no  dose-limiting  toxicity  was
observed. Ex vivo  analysis  of  blood  samples  from  this  Phase  1  trial  also  showed  that  increased  cytokine  inhibition  was
achieved with these higher doses of ATI-450. No serious adverse events were reported and all adverse events were mild to
moderate.  The  most  common  adverse  events  (reported  by  2  or  more  subjects  who  received  ATI-450)  were  headache,
dizziness,  nausea,  parasthesia  and,  in  the  post-dosing  safety  follow-up  phase  of  the  trial,  dry  skin.  These  adverse  events
were all mild in severity. A final analysis of this trial is underway.

Moderate to Severe Rheumatoid Arthritis

Following  the  completion  of  the  first  Phase  1  clinical  trial,  in  March  2020  we  initiated  a  12-week,  Phase  2a,
multicenter, randomized, investigator and patient-blind, sponsor-unblinded, parallel group, placebo-controlled clinical trial
to  investigate  the  safety,  tolerability,  pharmacokinetics  and  pharmacodynamics  of  ATI-450  in  subjects  with  moderate  to
severe rheumatoid arthritis (ATI-450-RA-201). In the trial, 19 subjects were randomized in a 3:1 ratio (seventeen subjects
[15 in the treatment arm and two in the placebo arm] completed treatment) and received either ATI-450 at 50 mg twice
daily or placebo, in combination with methotrexate, for 12 weeks. Preliminary topline data from this trial showed that ATI-
450  demonstrated  durable  clinical  activity,  as  defined  by  a  marked  and  sustained  reduction  in  DAS28-CRP  and
improvement  of  ACR20/50/70  responses  over  12  weeks.  ATI-450  was  generally  well  tolerated.  All  adverse  events  were
mild  to  moderate.  The  most  common  adverse  events  (each  reported  in  2  subjects)  were  urinary  tract  infection,  or  UTI,
elevated lipids and ventricular extrasystoles, all of which were determined to be unrelated to treatment except for one UTI.
Two subjects withdrew from the trial, one in the treatment arm and one in the placebo arm. The subject in the treatment
arm withdrew due to palpitations, which were unrelated to the trial medication, and an elevated creatine phosphokinase, or
CPK, which was determined by the site investigator to be treatment-related. The subject in the placebo arm withdrew as a
result of prohibited medication needed to treat muscle strain. There was one non-treatment-related serious adverse event
(COVID-19)  reported  in  the  four-week  safety  follow-up  phase  of  the  trial  in  a  subject  who  was  no  longer  receiving
treatment.

An interim analysis (11 treatment, two placebo) of ex vivo stimulated cytokines from blood samples taken from
the treatment arm showed a marked and durable inhibition of TNFα, IL1β, IL6, and IL8 over the 12 week dosing period.
Similarly, analysis of endogenous inflammation biomarkers also demonstrated a marked and sustained inhibition of median
concentrations of hsCRP, TNFα, IL6, IL8 and MIP1β in the treatment arm over the 12-week period.

We plan to submit for publication a full analysis of the Phase 2a data in a peer-reviewed scientific journal which
will  include  data  from  other  secondary  and  exploratory  endpoints  evaluated  in  the  trial,  including  the  four-week  safety
follow-up data and a full analysis of MRI, pharmacodynamic and pharmacokinetic data. Based on the results observed in
the  Phase  2a  trial,  we  intend  to  progress  ATI-450  into  a  Phase  2b  trial  in  moderate  to  severe  rheumatoid  arthritis  in  the
second half of 2021.

Cryopyrin-associated Periodic Syndrome

In  November  2020,  we  initiated  a  Phase  2a  multicenter,  open-label,  single-arm  clinical  trial  to  investigate  the
safety,  tolerability,  efficacy  and  pharmacodynamics  of  ATI-450  for  the  maintenance  of  remission  in  subjects  with
cryopyrin-associated periodic syndrome, or CAPS, previously managed with anti-IL1 therapy (ATI-450-CAPS-201). Due
to the COVID-19 pandemic, subject enrollment in this trial was paused. As a result of the ongoing pandemic and given the
positive  preliminary  topline  data  from  the  ATI-450-RA-201  trial,  we  have  decided  to  focus  our  efforts  and  resources  on
other immuno-inflammatory diseases.

COVID-19

We also supported an investigator-initiated Phase 2a, randomized, double-blind, placebo-controlled clinical trial to
investigate the safety and efficacy of ATI-450, when used in addition to standard of care therapy, as a potential treatment
for cytokine release syndrome in hospitalized patients with COVID-19. The primary endpoint in this trial is the proportion
of subjects who are free from respiratory failure by day 14. We provided funding and clinical drug supply to the University
of Kansas Medical Center, the sponsor of the trial. The trial included 20 subjects and is completed. We expect data to be
available in the first half of 2021.

ATI-1777, an Investigational Topical “Soft” JAK 1/3 Inhibitor

In June 2020, we submitted an IND for ATI-1777, an investigational topical “soft” JAK 1/3 inhibitor compound,
for the treatment of moderate to severe atopic dermatitis. “Soft” JAK inhibitors are designed to be topically applied and
active  in  the  skin,  but  rapidly  metabolized  and  inactivated  when  they  enter  the  bloodstream,  which  may  result  in  low
systemic exposure.

In  October  2020,  we  initiated  a  Phase  2a,  multicenter,  randomized,  double-blind,  vehicle-controlled,  parallel-
group  clinical  trial  to  determine  the  efficacy,  safety,  tolerability  and  pharmacokinetics  of  ATI-1777  in  subjects  with
moderate to severe atopic dermatitis (ATI-1777-AD-201). We expect data to be available mid-year 2021.

ATI-2138, an Investigational ITJ Inhibitor

We  are  also  developing  ATI-2138,  an  investigational  oral  ITK/TXK/JAK3,  or  ITJ,  inhibitor  compound,  as  a
potential treatment for psoriasis and/or inflammatory bowel disease, which are both T-cell mediated autoimmune diseases.
  The  ITJ  compound  interrupts  T  cell  signaling  through  the  combined  inhibition  of  ITK/TXK/JAK3  pathways  in
lymphocytes. We expect to file an IND for ATI-2138 in the second half of 2021.

Our Other Drug Candidates

We continue to seek third-party partners for our dermatology investigational drug candidate A-101 45% Topical

Solution as a potential treatment for common warts (verruca vulgaris).

Manufacturing and Supply

We  do  not  have  any  manufacturing  facilities.    We  rely  on  third  parties  for  the  manufacture  of  preclinical  and

clinical supplies for our drug candidates.

Competition

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong
emphasis on proprietary drugs. While we believe that our knowledge, experience and scientific resources provide us with
competitive  advantages,  we  face  potential  competition  from  many  different  sources,  including  major  pharmaceutical,
biotechnology and specialty pharmaceutical companies, academic institutions and governmental agencies and public and
private research institutions. Our drug candidates, if approved, will compete with existing treatments and new treatments
that may become available in the future.

Table of Contents

With  respect  to  ATI-450  as  a  potential  treatment  for  moderate  to  severe  rheumatoid  arthritis,  there  are  several
different  types  of  therapies  in  the  rheumatoid  arthritis  market.  Medications  for  the  treatment  of  rheumatoid  arthritis
currently fall into two categories: drugs that ease symptoms such as nonsteroidal anti-inflammatory drugs and drugs that
slow disease activity. Drugs that slow disease activity include corticosteroids and disease-modifying anti-rheumatic drugs,
or DMARDs. Disease-modifying drugs include conventional DMARDs such as methotrexate, sulfasalazine, leflunomide,
hydroxychloroquine,  biologic  DMARDs  (monoclonal  antibodies  which  inhibit  targets  such  as  TNF,  IL1,  IL6  and
costimulatory signaling mechanisms), and targeted synthetic DMARDs such as JAK inhibitors. These types of drugs are
produced and sold by large pharmaceutical companies, including AbbVie, Amgen, Bristol Myers Squibb, Eli Lilly, Johnson
& Johnson, Merck, Pfizer, and Roche, among others. In addition, we are aware of a number of companies developing and
conducting clinical trials for investigational drug candidates, including biosimilars, that, if approved, could compete with
ATI-450, if approved, for the treatment of rheumatoid arthritis.

With  respect  to  ATI-1777  as  a  potential  treatment  for  moderate  to  severe  atopic  dermatitis,  there  are  several
different types of therapies in the atopic dermatitis market, such as biologics, oral and topical corticosteroids, injectable and
oral  methotrexate  products,  oral  and  topical  calcineurin  inhibitors,  oral  mycophenolate  products,  other  JAK  inhibitors,
other oral antibiotics and antihistamines and phototherapy. There are also several prescription, non-prescription and over-
the-counter, or OTC, topical products, including PDE4 inhibitors, utilized to treat atopic dermatitis. These types of drugs
are  produced  and  sold  by  large  pharmaceutical  companies,  including  Sanofi  and  Regeneron  Pharmaceuticals,  Inc.,  and
Pfizer. In addition, we are aware of a number of companies including large pharmaceutical companies, such as AbbVie, Eli
Lilly,  Novartis,  Incyte,  Pfizer  and  LEO  Pharma  A/S  developing  and  conducting  clinical  trials  for  investigational  drug
candidates, that, if approved, could compete with ATI-1777, if approved, for the treatment of atopic dermatitis.

The  commercial  opportunity  for  our  drug  candidates,  if  approved,  could  be  reduced  or  eliminated  if  our
competitors develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more
convenient or are less expensive than any drug we may develop. Our competitors also may obtain FDA or other regulatory
approval for their drug candidates more rapidly than our potential third-party partners may obtain approval for our drug
candidates, which could result in our competitors establishing a strong market position before our drug candidates are able
to enter the market.

Many of the companies against which we are competing, or against which we may compete in the future, have
significantly  greater  financial  resources  and  expertise  in  research  and  development,  manufacturing,  and  preclinical  and
clinical development than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result
in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies
may  also  prove  to  be  significant  competitors,  particularly  through  collaborative  arrangements  with  large  and  established
companies.  These  competitors  also  compete  with  us  in  recruiting  and  retaining  qualified  scientific  and  management
personnel and establishing clinical trial sites and subject registration for clinical trials, as well as in acquiring technologies
complementary to, or that may be necessary for, our development programs.

Intellectual Property

Our  success  depends  in  large  part  upon  our  ability  to  obtain  and  maintain  proprietary  protection  for  our  drug
candidates  and  to  operate  without  infringing  the  proprietary  rights  of  others.  We  seek  to  avoid  the  latter  by  monitoring
patents  and  publications  that  may  affect  our  business,  and  to  the  extent  we  identify  such  developments,  evaluating  and
taking  appropriate  courses  of  action.  Our  policy  is  to  protect  our  proprietary  position  by,  among  other  methods,  filing
patent applications on inventions that are important to the development and conduct of our business with the U.S. Patent
and Trademark Office, or USPTO, and its foreign counterparts.

With respect to our MK2 signaling pathway inhibitor development program, we own numerous issued patents and
pending applications to novel MK2 pathway inhibitors, including our lead candidate ATI-450, and various methods of use
that expire, or would expire, between 2031 and 2041, subject to any applicable patent term adjustment or extension that
may be available in a particular country.  For example, we own two U.S. patents and pending applications in the European
Union and other foreign countries directed to ATI-450 and analogs thereof and certain methods of using the same.  The
U.S.  patents  expire  in  2034  and  any  claims  that  may  issue  from  the  pending  applications  expire  in  2034,  subject  to  any
applicable adjustment or extension. We also own a Patent Cooperation Treaty, or PCT, application directed to deuterated
forms  of  ATI-450  and  methods  of  use,  which,  if  issued,  would  expire  in  2040,  subject  to  any  applicable  adjustment  or
extension. Further, we own numerous provisional applications directed to certain methods of using ATI-

7

Table of Contents

450, methods of manufacturing ATI-450 and crystal forms of ATI-450, which, if issued, would each expire in 2041, subject
to any applicable adjustment or extension.

With  respect  to  our  “soft”  JAK  inhibitor  development  program,  we  own  one  issued  U.S.  patent  and  numerous
pending  applications  in  the  U.S.  and  foreign  countries  to  novel  “soft”  JAK  inhibitors  and  various  methods  of  use  that
expire, or would expire, between 2038 and 2041, subject to any applicable patent term adjustment or extension that may be
available  in  a  particular  country.    For  example,  we  own  one  allowed  U.S.  application  and  pending  applications  in  the
European  Union  and  other  foreign  countries  directed  to  various  novel  inhibitors  of  JAK1  and/or  JAK3,  including  ATI-
1777,  and  methods  of  using  the  same,  which,  if  issued,  would  expire  in  2038,  subject  to  any  applicable  adjustment  or
extension. We also own two provisional applications directed to topical formulations and crystal forms of ATI-1777, which,
if issued, would expire in 2041, subject to any applicable adjustment or extension.

With  respect  to  our  ITK  inhibitor  development  program,  we  own  numerous  issued  U.S.  patents  and  pending
applications in the U.S. and foreign countries directed to novel inhibitors of ITK and methods of use that expire, or would
expire, between 2035 and 2039, subject to any applicable patent term adjustment or extension that may be available in a
particular country. We also own pending U.S., European Union and other foreign country applications directed to ATI-2138
and  analogs  thereof  and  methods  of  using  the  same,  which,  if  issued,  would  expire  in  2039,  subject  to  any  applicable
adjustment or extension.

Patents extend for varying periods according to the date of patent filing or grant and the legal term of patents in
various  countries  where  patent  protection  is  obtained.  The  actual  protection  afforded  by  a  patent,  which  can  vary  from
country to country, depends on the type of patent, the scope of its coverage and the availability of legal remedies in the
country. In most countries in which we file, the patent term is 20 years from the earliest date of filing a non-provisional
patent application. In the United States, a patent term may be shortened if a patent is terminally disclaimed over another
patent or as a result of delays in patent prosecution by the patentee, and a patent’s term may be lengthened by patent term
adjustment, which compensates a patentee for administrative delays by the USPTO in granting a patent or by patent term
extension, which compensates a patentee for delays at the FDA. The patent term of a European patent is 20 years from its
filing date; however, unlike in the United States, the European patent does not grant patent term adjustments. The European
Union  does  have  a  compensation  program  similar  to  patent  term  extension  called  supplementary  patent  certificate  that
would effectively extend patent protection for up to five years.

We  also  use  other  forms  of  protection,  such  as  trademark,  copyright,  and  trade  secret  protection,  to  protect  our
intellectual property, particularly where we do not believe patent protection is appropriate or obtainable. We aim to take
advantage of all of the intellectual property rights that are available to us and believe that this comprehensive approach will
provide us with proprietary positions for our drug candidates, where available.

We  also  protect  our  proprietary  information  by  requiring  our  employees,  consultants,  contractors  and  other
advisors  to  execute  nondisclosure  and  assignment  of  invention  agreements  upon  commencement  of  their  respective
employment  or  engagement.  Agreements  with  our  employees  also  prevent  them  from  bringing  the  proprietary  rights  of
third  parties  to  us.  In  addition,  we  also  require  confidentiality  or  service  agreements  from  third  parties  that  receive  our
confidential information or materials.

Acquisition and License Agreements

Agreement and Plan of Merger with Confluence

In  August  2017,  we  entered  into  an  Agreement  and  Plan  of  Merger,  or  the  Confluence  Agreement,  with
Confluence,  Aclaris  Life  Sciences,  Inc.,  our  wholly-owned  subsidiary,  or  Merger  Sub,  and  Fortis  Advisors  LLC,  as
representative of the former equity holders of Confluence.  Pursuant to the terms of the Confluence Agreement, the Merger
Sub  merged  with  and  into  Confluence,  with  Confluence  surviving  as  our  wholly-owned  subsidiary,  resulting  in  our
acquisition of 100% of the outstanding shares of Confluence. We paid closing consideration of $10.3 million in cash and
issued 349,527 shares of our common stock with a fair value of $9.7 million to the former Confluence equity holders. 

In November 2018, a development milestone specified in the Confluence Agreement was achieved, as a result of
which we paid the former Confluence equity holders $2.5 million in cash and issued 253,208 shares of our common stock
with a fair value of $2.2 million.  Under the Confluence Agreement, we also agreed to pay the former Confluence equity
holders aggregate remaining contingent consideration of up to $75.0 million based upon the achievement of specified

8

Table of Contents

regulatory  and  commercial  milestones  set  forth  in  the  Confluence  Agreement.  In  addition,  we  have  agreed  to  pay  the
former Confluence equity holders future royalty payments calculated as a low single-digit percentage of annual net sales,
subject to specified reductions, limitations and other adjustments, until the date that all of the patent rights for that product
have expired, as determined on a country-by-country and product-by-product basis or, in specified circumstances, ten years
from the first commercial sale of such product.  In addition to the payments described above, if we sell, license or transfer
any of the intellectual property acquired from Confluence pursuant to the Confluence Agreement to a third party, we will
be obligated to pay the former Confluence equity holders a portion of any consideration received from such sale, license or
transfer in specified circumstances.

Government Regulation and Product Approval

Governmental  authorities  in  the  United  States,  at  the  federal,  state  and  local  level,  and  analogous  authorities  in
other  countries  extensively  regulate,  among  other  things,  the  research,  development,  testing,  manufacture,  safety
surveillance,  efficacy,  quality  control,  labeling,  packaging,  distribution,  record  keeping,  promotion,  storage,  advertising,
distribution, marketing, sale, export and import, and the reporting of safety and other post-market information of products
such as the ones we are developing. A drug candidate must be approved by the FDA before it may be legally promoted in
the United States and by comparable foreign regulatory authorities before marketing in other jurisdictions.  The process of
obtaining regulatory approvals and the subsequent compliance with applicable federal, state, local and foreign statutes and
regulations  require  the  expenditure  of  substantial  time  and  resources.  Failure  to  comply  with  the  applicable  U.S.
requirements  at  any  time  during  the  product  development  process,  approval  process  or  after  approval  may  subject  an
applicant and/or sponsor to a variety of administrative or judicial sanctions, including refusal by regulatory authorities to
approve applications, withdrawal of an approval, imposition of a clinical hold, import/export delays, issuance of warning
letters  and  untitled  letters,  product  recalls,  product  seizures,  total  or  partial  suspension  of  production  or  distribution,
injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations
and penalties brought by FDA and the Department of Justice or other governmental entities.

United States Government Regulation

NDA Approval Processes

In  the  United  States,  the  FDA  regulates  drug  and  medical  device  products  under  the  Federal  Food,  Drug,  and
Cosmetic  Act,  or  FDCA,  and  its  implementing  regulations.    The  FDA’s  Center  for  Drug  Evaluation  and  Research  has
primary  jurisdiction  over  the  premarket  development,  review  and  approval  of  our  drug  candidates.  Accordingly,  we  are
investigating our drug candidates pursuant to IND applications and expect that any potential third-party partners that we
may consummate a transaction with would seek approval through the New Drug Application, or NDA, pathway.

An  applicant  seeking  approval  to  market  and  distribute  a  new  drug  product  in  the  United  States  must  typically

undertake the following:

● completion of preclinical laboratory tests, animal studies and formulation studies in compliance with the FDA’s

good laboratory practice regulations;

● submission to the FDA of an IND which must take effect before clinical trials may begin;
● approval by an independent institutional review board, or IRB, representing each clinical site before clinical

testing may be initiated at the clinical site;

● performance of adequate and well-controlled clinical trials in accordance with good clinical practice, or GCP,

regulations to establish the safety and efficacy of the proposed drug product for each indication;

● preparation and submission to the FDA of an NDA;
● review of the NDA by an FDA advisory committee, if applicable;
● satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which the
product or its components are produced to assess compliance with current good manufacturing practices, or
cGMP, and regulations to assure that the facilities, methods and controls are adequate to preserve the product’s
identity, strength, quality and purity;

● payment of user fees and securing FDA approval of the NDA; and
● compliance with any post-approval requirements, including potential requirements for a risk evaluation and

mitigation strategy and post-approval studies required by the FDA.

9

Table of Contents

Once  a  drug  candidate  is  identified  for  development,  it  enters  the  preclinical  or  nonclinical  testing  stage.
Preclinical studies include laboratory evaluations of product chemistry, pharmacology, toxicity and formulation. An IND
sponsor must submit the results of the preclinical studies, together with manufacturing information and analytical data, to
the  FDA  as  part  of  the  IND.  Some  preclinical  studies  may  continue  even  after  the  IND  is  submitted.  In  addition  to
including  the  results  of  the  preclinical  studies,  the  IND  will  also  include  a  protocol  detailing,  among  other  things,  the
objectives of the clinical trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated
if the first phase lends itself to an efficacy determination. The IND automatically becomes effective 30 days after receipt by
the FDA, unless the FDA, within the 30-day time period, places the IND on clinical hold. In such a case, the IND sponsor
and the FDA must resolve any outstanding concerns before clinical trials can begin. A clinical hold may occur at any time
during the life of an IND, and may affect one or more specific clinical trials or all clinical trials conducted under the IND.

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance
with  current  GCP  regulations.  They  must  be  conducted  under  protocols  detailing  the  objectives  of  the  trial,  dosing
procedures, research subject selection and exclusion criteria, and the safety and effectiveness criteria to be evaluated. Each
protocol must be submitted to the FDA as part of the IND, and progress reports detailing the status of the clinical trials
must  be  submitted  to  the  FDA  annually.  Sponsors  also  must  timely  report  to  the  FDA  serious  and  unexpected  adverse
reactions, any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol
or investigator brochure, and any findings from other studies or animal or in vitro testing that suggest a significant risk in
humans  exposed  to  the  drug.  An  IRB  at  each  institution  participating  in  the  clinical  trial  must  review  and  approve  the
protocol before the clinical trial commences at that institution and must also approve the information regarding the trial and
the consent form that must be provided to each research subject or the subject’s legal representative, monitor the study until
completed and otherwise comply with IRB regulations.

Clinical trials are typically conducted in three sequential phases that may overlap or be combined:

● Phase 1.    The  drug  is  initially  introduced  into  healthy  human  subjects  and  tested  for  safety,  dosage  tolerance,
absorption, metabolism, distribution and elimination. In the case of some products for severe or life-threatening
diseases, such as cancer, and especially when the product may be inherently too toxic to ethically administer to
healthy volunteers, the initial human testing is often conducted in patients who already have the condition.

● Phase 2.  Clinical trials are performed on a limited patient population intended to identify possible adverse effects
and  safety  risks,  to  preliminarily  evaluate  the  efficacy  of  the  product  for  specific  targeted  diseases  and  to
determine dosage tolerance and optimal dosage.

● Phase 3.  If a drug candidate is found to be potentially effective and to have an acceptable safety profile in Phase
2 clinical trials, the clinical trial program will be expanded to Phase 3 clinical trials to further evaluate dosage,
clinical efficacy and safety in an expanded patient population at geographically dispersed clinical trial sites. These
trials  are  intended  to  establish  the  overall  risk-benefit  ratio  of  the  product  and  provide  an  adequate  basis  for
product approval and labeling claims.

Phase 4 clinical trials are conducted after approval to gain additional experience from the treatment of patients in
the  intended  therapeutic  indication  and  to  document  a  clinical  benefit  in  the  case  of  drugs  approved  under  accelerated
approval regulations, or when otherwise requested by the FDA in the form of post-market requirements or commitments.
Failure to promptly conduct any required Phase 4 clinical trials could result in withdrawal of approval.

Clinical  trials  are  inherently  uncertain,  and  Phase  1,  Phase  2  and  Phase  3  testing  may  not  be  successfully
completed. The FDA or the sponsor may suspend a clinical trial at any time for a variety of reasons, including a finding
that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or
terminate approval of a clinical trial at its institution 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. In some cases, clinical trials are
overseen  by  an  independent  group  of  qualified  experts  organized  by  the  trial  sponsor,  which  is  called  the  clinical
monitoring board or data safety monitoring board. This group provides authorization for whether or not a trial may move
forward at designated check points. These decisions are based on the limited access to data from the ongoing trial.

During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points.
These points may be prior to the submission of an IND, at the end of Phase 2 and before an NDA is submitted. Meetings at
other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the
data  gathered  to  date  and  for  the  FDA  to  provide  advice  on  the  next  phase  of  development.  Sponsors  typically  use  the
meeting at the end of Phase 2 to discuss their Phase 2 clinical trial results and present their plans for the pivotal Phase 3
clinical trial or trials that they believe will support the approval of the new drug.

10

Table of Contents

Concurrent  with  clinical  trials,  sponsors  usually  complete  additional  animal  safety  studies  and  also  develop
additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing
commercial quantities of the product in accordance with cGMP requirements. The manufacturing process must be capable
of consistently producing quality batches of the drug and the manufacturer must develop methods for testing the quality,
purity and potency of the 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 proposed shelf-
life.

The  results  of  product  development,  preclinical  studies  and  clinical  trials,  along  with  descriptions  of  the
manufacturing process, analytical tests and other control mechanisms, proposed labeling and other relevant information are
submitted to the FDA as part of an NDA requesting approval to market the product. The submission of an NDA is subject
to the payment of user fees, but a waiver of such fees may be obtained under specified circumstances. The FDA reviews all
NDAs  submitted  for  a  period  of  60  days  to  ensure  that  they  are  sufficiently  complete  for  substantive  review  before  it
accepts them for filing. It may request additional information rather than accept an NDA for filing. In this event, the NDA
must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA
accepts it for filing.

During the approval process, the FDA also will determine whether a risk evaluation and mitigation strategy, or
REMS, is necessary to assure the safe use of the product. If the FDA concludes a REMS is needed, the sponsor of the NDA
must submit a proposed REMS, and the FDA will not approve the application without an approved REMS, if required. A
REMS can substantially increase the costs of obtaining approval. The FDA could also require a special warning, known as
a boxed warning, to be included in the product label in order to highlight a particular safety risk.

Once  the  submission  is  accepted  for  filing,  the  FDA  begins  an  in-depth  review.  The  FDA  reviews  an  NDA  to
determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is
cGMP-compliant. The FDA may refer the NDA to an advisory committee for review and recommendation as to whether
the  application  should  be  approved  and  under  what  conditions.  The  FDA  is  not  bound  by  the  recommendation  of  an
advisory committee, but it generally follows such recommendations. NDAs receive either standard or priority review. A
drug representing a significant improvement in treatment, prevention or diagnosis of disease may receive priority review. A
priority review designation is intended to direct overall attention and resources to the evaluation of such applications, and
to shorten the FDA’s goal for taking action on the NDA from ten months to six months from filing of the NDA. After the
FDA  evaluates  the  NDA  and  conducts  inspections  of  manufacturing  facilities  where  the  drug  product  and/or  its  active
pharmaceutical ingredient will be produced, it may issue an approval letter or a Complete Response Letter. An approval
letter  authorizes  commercial  marketing  of  the  drug  with  specific  prescribing  information  for  specific  indications.  A
Complete Response Letter indicates that the review cycle of the application is complete, and the application is not ready for
approval.  A  Complete  Response  Letter  may  require  additional  clinical  data  and/or  an  additional  pivotal  Phase  3  clinical
trial(s), and/or other significant, expensive and time-consuming requirements related to clinical trials, preclinical studies or
manufacturing. Even if such data and information are submitted, the FDA may ultimately decide that the NDA does not
satisfy the criteria for approval.

Post-approval Requirements

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation
by  the  FDA  and  other  governmental  agencies,  including,  among  other  things,  requirements  relating  to  recordkeeping,
periodic  reporting,  product  sampling  and  distribution,  advertising  and  promotion,  and  reporting  of  adverse  experiences
with  the  product.  Once  an  approval  is  granted,  the  FDA  may  withdraw  the  approval  if  compliance  with  regulatory
requirements  is  not  maintained  or  if  problems  occur  after  the  product  reaches  the  market.  Later  discovery  of  previously
unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product
from  the  market.  After  approval,  some  types  of  changes  to  the  approved  product,  such  as  adding  new  indications,
manufacturing  changes  and  additional  labeling  claims,  are  subject  to  further  FDA  review  and  approval.  There  are  also
continuing, annual user fee requirements for products and the establishments at which such products are manufactured, as
well  as  new  application  fees  for  certain  supplemental  applications.  In  addition,  the  FDA  may  require  testing  and
surveillance  programs  to  monitor  the  effect  of  approved  products  that  have  been  commercialized,  and  the  FDA  has  the
power to prevent or limit further marketing of a product based on the results of these post-marketing programs.

11

Table of Contents

Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required
to  register  their  establishments  with  the  FDA  and  certain  state  agencies,  and  are  subject  to  periodic  unannounced
inspections  by  the  FDA  and  some  state  agencies  for  compliance  with  GMP  regulations  and  other  laws.  The  FDA  has
promulgated  specific  requirements  for  drug  cGMPs  and  device  cGMPs  embodied  in  the  Quality  System  Regulation.
Changes  to  the  manufacturing  process  are  strictly  regulated  and  often  require  prior  FDA  approval  before  being
implemented. FDA regulations also require investigation and correction of any deviations from cGMP requirements and
impose  reporting  and  documentation  requirements  upon  the  sponsor  and  any  third-party  manufacturers  that  the  sponsor
may decide to use. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production
and quality control to maintain cGMP compliance.

Failure to comply with the applicable U.S. requirements at any time during the product development process or
approval  process,  or  after  approval,  may  subject  us  to  administrative  or  judicial  sanctions,  any  of  which  could  have  a
material adverse effect on us. These sanctions could include:

● refusal to approve pending applications;
● withdrawal of an approval;
● imposition of a clinical hold;
● warning letters;
● product seizures or detention, or refusal to permit the import or export of products;
● restrictions on the marketing or manufacturing of the product;
● total or partial suspension of production or distribution or product recalls; or
● injunctions, fines, disgorgement, or civil or criminal penalties.

The FDA strictly regulates the marketing, labeling, advertising and promotion of drug products that are placed on
the  market.  Drugs  may  be  promoted  only  for  the  approved  indications  and  in  accordance  with  the  provisions  of  the
approved label.  However, companies may share truthful and not misleading information that is otherwise consistent with
the product’s FDA approved labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting
the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to
significant liability. However, physicians may, in their independent medical judgment, prescribe legally available products
for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments but the FDA does
restrict manufacturer’s communications on the subject of off-label use of their products.

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

Non-patent Exclusivity

The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first
applicant  to  obtain  approval  of  an  NDA  for  a  new  chemical  entity,  or  NCE.  A  drug  is  an  NCE  if  the  FDA  has  not
previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for
the action of the drug substance.  If market exclusivity is granted for an NCE, during the exclusivity period, the FDA may
not  accept  for  review  or  approve  an  abbreviated  new  drug  application,  or  ANDA,  or  a  505(b)(2)  NDA  submitted  by
another company for another version of such drug where the applicant does not own or have a legal right of reference to all
the data required for approval. However, an application may be submitted after four years if it contains a certification of
patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder.

The FDCA also provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA if
new  clinical  investigations,  other  than  bioavailability  studies,  that  were  conducted  or  sponsored  by  the  applicant  are
deemed by the FDA to be essential to the approval of the application, for example new indications, dosages, dosage forms
or strengths of an existing drug.  This three-year exclusivity covers only the conditions associated with the new clinical
investigations and prohibits the FDA from approving an ANDA or a 505(b)(2) NDA submitted by another company with
overlapping conditions associated with the new clinical investigations for the three-year period.  Clinical investigation

12

Table of Contents

exclusivity does not prohibit the FDA from approving ANDAs for drugs containing the original active agent. Five-year and
three-year  exclusivity  will  not  delay  the  submission  or  approval  of  an  NDA  for  the  same  drug.  However,  an  applicant
submitting an NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate
and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Orphan Drug Designation

Under  the  Orphan  Drug  Act,  the  FDA  may  grant  orphan  drug  designation  to  products  intended  to  treat  a  rare
disease  or  condition—generally  one  that  affects  fewer  than  200,000  individuals  in  the  United  States.  Orphan  drug
designation  must  be  requested  before  submitting  the  NDA.  After  the  FDA  grants  orphan  drug  designation,  the  FDA
publicly discloses the drug’s identity and its intended orphan use. Orphan drug designation does not convey any advantage
in, or shorten the duration of, the regulatory review and approval process. The first active moiety to be approved to treat a
disease with FDA’s orphan drug designation is entitled to a seven-year period of marketing exclusivity in the United States
for  that  product,  for  that  indication.  During  the  seven-year  exclusivity  period,  the  FDA  may  not  approve  any  other
applications  to  market  the  same  drug  for  the  same  orphan  indication,  regardless  of  patent  status,  except  in  limited
circumstances, such as a showing of clinical superiority to the product with orphan exclusivity or if the FDA finds that the
holder of the orphan exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug
to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does
not prevent the FDA from approving a different chemical/biological entity for the same disease or condition. An orphan
drug designation also does not preclude the same drug from being developed for a different disease or condition. Among
the other benefits of orphan drug designation are tax credits for certain research expenses and a waiver of the application
user fee.

Regulation Outside of the United States

Even  if  we  obtain  FDA  approval  for  a  drug  candidate,  we  must  obtain  approval  by  the  comparable  regulatory
authorities  of  countries  outside  of  the  United  States  before  we  can  commence  clinical  trials  in  such  countries,  and  our
potential  third-party  partners  must  obtain  approval  of  the  regulators  of  such  countries  or  economic  areas,  such  as  the
European Union, before they may market any of our drug candidates in those countries or areas. The approval process and
requirements  governing  the  conduct  of  clinical  trials,  product  licensing  and  promotion,  pricing  and  reimbursement  vary
greatly by geographic region, and the time may be longer or shorter than that required for FDA approval.

In the European Economic Area, or EEA, which is composed of the Member States of the European Union plus
Norway,  Iceland  and  Liechtenstein,  medicinal  products  can  only  be  commercialized  after  obtaining  a  Marketing
Authorization, or MA.

There are two types of MAs:

● The Community MA, which is issued by the European Commission through the Centralized Procedure, based on
the  opinion  of  the  Committee  for  Medicinal  Products  for  Human  Use,  or  CHMP,  of  the  European  Medicines
Agency,  or  EMA,  and  which  is  valid  throughout  the  entire  territory  of  the  EEA.  The  Centralized  Procedure  is
mandatory for certain types of products, such as biotechnology medicinal products, orphan medicinal products,
and medicinal products indicated for the treatment of AIDS, cancer, neurodegenerative disorders, diabetes, auto-
immune and viral diseases. The Centralized Procedure is optional for products containing a new active substance
not  yet  authorized  in  the  EEA,  or  for  products  that  constitute  a  significant  therapeutic,  scientific  or  technical
innovation or which are in the interest of public health in the European Union. Under the Centralized Procedure,
the maximum timeframe for the evaluation of a marketing authorization application is 210 days (excluding clock
stops,  when  additional  written  or  oral  information  is  to  be  provided  by  the  applicant  in  response  to  questions
asked  by  the  CHMP).  Accelerated  evaluation  might  be  granted  by  the  CHMP  in  exceptional  cases,  when  the
authorization of a medicinal product is of major interest from the point of view of public health and, in particular,
from  the  viewpoint  of  therapeutic  innovation.  Under  the  accelerated  procedure,  the  standard  210  days  review
period is reduced to 150 days.

● National MAs, which are issued by the competent authorities of the Member States of the EEA and only cover
their  respective  territory,  are  available  for  products  not  falling  within  the  mandatory  scope  of  the  Centralized
Procedure.  Where  a  product  has  already  been  authorized  for  marketing  in  a  Member  State  of  the  EEA,  this
National MA can be recognized in another Member State through the Mutual Recognition Procedure. If the

13

Table of Contents

product  has  not  received  a  National  MA  in  any  Member  State  at  the  time  of  application,  it  can  be  approved
simultaneously in various Member States through the Decentralized Procedure.

In the EEA, upon receiving marketing authorization, new chemical entities generally receive eight years of data
exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities in
the  EEA  from  referencing  the  innovator’s  data  to  assess  a  generic  application.  During  the  additional  two-year  period  of
market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no
generic  product  can  be  marketed  until  the  expiration  of  the  market  exclusivity.  However,  there  is  no  guarantee  that  a
product will be considered by the EEA’s regulatory authorities to be a new chemical entity, and products may not qualify
for data exclusivity.

Other Health Care Laws

Health care providers, physicians and third-party payors in the United States and elsewhere will play a primary
role in the recommendation and prescription of any of our drug candidates for which marketing approval is obtained. Our
potential third-party partners’ arrangements with third-party payors, health care professionals and customers may expose
them to broadly applicable fraud and abuse and other health care laws and regulations, including, without limitation, the
federal  Anti-Kickback  Statute  and  the  federal  civil  False  Claims  Act,  that  may  constrain  the  business  or  financial
arrangements  and  relationships  through  which  they  sell,  market  and  distribute  any  drug  candidates  for  which  marketing
approval is obtained. In addition, we and our potential third-party partners may be subject to transparency laws and patient
privacy regulation by the federal government and by the U.S. states and foreign jurisdictions in which we or they conduct
business.

The  federal  Anti-Kickback  Statute  makes  it  illegal  for  any  person  or  entity,  including  a  prescription  drug
manufacturer (or a party acting on its behalf) to knowingly and willfully, directly or indirectly, solicit, receive, offer, or pay
any remuneration that is intended to induce the referral of business, including the purchase, order, or lease of any good,
facility,  item  or  service  for  which  payment  may  be  made  under  a  federal  health  care  program,  such  as  Medicare  or
Medicaid. The term “remuneration” has been broadly interpreted to include anything of value. The Anti-Kickback Statute
has  been  interpreted  to  apply  to  arrangements  between  pharmaceutical  manufacturers  on  one  hand  and  prescribers,
purchasers, formulary managers, and beneficiaries on the other. Although there are a number of statutory exceptions and
regulatory  safe  harbors  protecting  some  common  activities  from  prosecution,  the  exceptions  and  safe  harbors  are  drawn
narrowly.  Practices  that  involve  remuneration  that  may  be  alleged  to  be  intended  to  induce  prescribing,  purchases  or
recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the
requirements  of  a  particular  applicable  statutory  exception  or  regulatory  safe  harbor  does  not  make  the  conduct  per  se
illegal under the Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis
based  on  a  cumulative  review  of  all  its  facts  and  circumstances.  Several  courts  have  interpreted  the  statute’s  intent
requirement  to  mean  that  if  any  one  purpose  of  an  arrangement  involving  remuneration  is  to  induce  referrals  of  federal
health care covered business, the Anti-Kickback Statute has been violated. Violations of this law are punishable by up to
ten years in prison, and can also result in criminal fines, civil monetary penalties, administrative penalties and exclusion
from participation in federal health care programs.

Additionally,  the  intent  standard  under  the  Anti-Kickback  Statute  was  amended  by  the  Patient  Protection  and
Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the
Affordable Care Act, to a stricter standard such that a person or entity no longer needs to have actual knowledge of the
statute or specific intent to violate it in order to have committed a violation. In addition, the Affordable Care Act codified
case law that 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 federal civil False Claims Act.

Federal false claims and false statement laws, including the federal civil False Claims Act, prohibits, among other
things, any person or entity from knowingly presenting, or causing to be presented, for payment to, or approval by, federal
programs, including Medicare and Medicaid, claims for items or services, including drugs, that are false or fraudulent or
not provided as claimed. Entities can be held liable under these laws if they are deemed to “cause” the submission of false
or fraudulent claims by, for example, providing inaccurate billing or coding information to customers, promoting a product
off-label, or for providing medically unnecessary services or items. In addition, activities relating to the sale and marketing
of products are subject to scrutiny under this law. Penalties for federal civil False Claims Act violations may include up to
three times the actual damages sustained by the government, plus mandatory civil penalties for each separate false claim,

the potential for exclusion from participation in federal health care programs, and, although the federal civil False Claims
Act is a civil statute, False Claims Act violations may also implicate various federal criminal statutes.  

The  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  prohibits  among  other
actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any health care benefit program,
including private third-party payors, knowingly and willfully embezzling or stealing from a health care benefit program,
willfully obstructing a criminal investigation of a health care offense, and knowingly and willfully falsifying, concealing or
covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery
of or payment for health care benefits, items or services. Like the Anti-Kickback Statute, the Affordable Care Act amended
the intent standard for the health care fraud statute under HIPAA such that a person or entity no longer needs to have actual
knowledge of the statute or specific intent to violate it in order to have committed a violation.

The  civil  monetary  penalties  statute  imposes  penalties  against  any  person  or  entity  that,  among  other  things,  is
determined to have presented or caused to be presented a claim to a federal health program that the person knows or should
know is for an item or service that was not provided as claimed or is false or fraudulent.

Also, many states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply
regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs. Additionally, to
the extent that a product is sold in a foreign country, the seller may be subject to similar foreign laws.

In  addition,  legislation  imposing  marketing  restrictions  and  transparency  requirements  on  pharmaceutical
manufacturers  has  been  enacted  at  the  state  and  federal  levels.    For  example,  the  Affordable  Care  Act  imposed,  among
other  things,  annual  reporting  requirements  to  the  Centers  for  Medicare  &  Medicaid  Services,  or  CMS,  for  covered
manufacturers for certain payments and other transfers of value provided to physicians (defined to include doctors, dentists,
optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by
physicians  and  their  immediate  family  members.  Beginning  in  2022,  applicable  manufacturers  will  also  be  required  to
report  information  regarding  payments  and  other  transfers  of  value  provided  during  the  previous  year  to  physician
assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, anesthesiologist assistants, and certified
nurse-midwives. Failure to submit timely, accurately and completely the required information for all payments, transfers of
value and ownership or investment interests may result in civil monetary penalties for “knowing failures.”  Certain states
also  mandate  implementation  of  compliance  programs,  impose  restrictions  on  drug  manufacturer  marketing  practices,
require  registration  of  certain  employees  engaged  in  marketing  activities  in  the  location,  and/or  require  the  tracking  and
reporting of gifts, compensation and other remuneration to physicians.  

We have developed a comprehensive compliance program that establishes internal controls to facilitate adherence
to  the  rules  and  program  requirements  to  which  we  are  subject.  Although  the  development  and  implementation  of
compliance programs designed to establish internal controls and facilitate compliance can mitigate the risk of investigation,
prosecution, and penalties assessed for violations of these laws, or any other laws that may apply to us, the risks cannot be
entirely eliminated. If our operations are found to be in violation of any such laws or any other governmental regulations,
we  may  be  subject  to  significant  penalties,  including,  without  limitation,  administrative,  civil,  and  criminal  penalties,
damages,  fines,  disgorgement,  imprisonment,  contractual  damages,  reputational  harm,  diminished  profits  and  future
earnings,  the  curtailment  or  restructuring  of  our  operations,  exclusion  from  participation  in  federal  and  state  health  care
programs,  additional  reporting  requirements  and  oversight  if  we  become  subject  to  a  corporate  integrity  agreement  or
similar  agreement  to  resolve  allegations  of  non-compliance  with  these  laws  and  individual  imprisonment,  any  of  which
could adversely affect our ability to operate our business and our financial results.

We may also be subject to data privacy and security regulation by both the federal government and the states in
which  we  conduct  our  business.  HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical
Health  Act,  or  HITECH,  and  their  implementing  regulations,  including  the  final  omnibus  rule  published  on  January  25,
2013,  mandates,  among  other  things,  the  adoption  of  uniform  standards  for  the  electronic  exchange  of  information  in
common health care transactions, as well as standards relating to the privacy and security of individually identifiable health
information, which require the adoption of administrative, physical and technical safeguards to protect such information.
Among  other  things,  HITECH  makes  HIPAA’s  security  standards  directly  applicable  to  “business  associates”,  namely
independent contractors or agents of HIPAA covered entities that create, receive or obtain protected health information in
connection with providing a service for or on behalf of a covered entity and their subcontractors that use, disclose, access,
or  otherwise  process  protected  health  information.  HITECH  also  increased  the  civil  and  criminal  penalties  that  may  be
imposed against covered entities and business associates, and gave state attorneys general new authority to file civil actions

15

Table of Contents

for  damages  or  injunctions  in  federal  courts  to  enforce  the  federal  HIPAA  laws  and  seek  attorneys’  fees  and  costs
associated  with  pursuing  federal  civil  actions.  In  addition,  certain  state  laws  govern  the  privacy  and  security  of  health
information in certain circumstances, some of which are more stringent than HIPAA and many of which differ from each
other in significant ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with
these laws, where applicable, can result in the imposition of significant civil and/or criminal penalties.

Health Care Reform

In the United States, there have been and continue to be a number of significant legislative initiatives to contain
health  care  costs.  For  example,  in  March  2010,  the  Affordable  Care  Act  was  passed,  which  has  had,  and  is  expected  to
continue  to  have,  a  significant  impact  on  the  health  care  industry.  The  Affordable  Care  Act  was  designed  to  expand
coverage for the uninsured and at the same time contain overall health care costs. With regard to pharmaceutical products,
among other things, the Affordable Care Act expanded and increased industry rebates for drugs covered under Medicaid
programs;  addressed  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; extended the rebate program to
individuals enrolled in Medicaid managed care organizations; established annual fees and taxes on manufacturers of certain
branded prescription drugs; made changes to the coverage requirements under the Medicare prescription drug benefit; and
established  a  new  Medicare  Part  D  coverage  gap  discount  program,  in  which  manufacturers,  as  a  condition  for  their
outpatient drugs to be covered under Medicare Part D, must agree to offer 70% point-of-sale discounts off negotiated prices
of applicable brand drugs to eligible beneficiaries during their coverage gap period.  Moreover, the Affordable Care Act
provided  incentives  to  programs  that  increase  the  federal  government’s  comparative  effectiveness  research  and
implemented  payment  system  reforms  including  a  national  pilot  program  on  payment  bundling  meant  to  encourage
hospitals, physicians and other providers to improve the coordination, quality and efficiency of certain health care services.

There remain judicial and Congressional challenges to certain aspects of the Affordable Care Act. While Congress
has  not  passed  comprehensive  repeal  legislation,  several  bills  affecting  the  implementation  of  certain  taxes  under  the
Affordable  Care  Act  have  been  signed  into  law.    The  Tax  Cuts  and  Jobs  Act  of  2017  includes  a  provision  repealing,
effective  January  1,  2019,  the  tax-based  shared  responsibility  payment  imposed  by  the  Affordable  Care  Act  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 addition, the 2020 federal spending package permanently eliminated, effective January 1, 2020,
the Affordable Care Act-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax
and, effective January 1, 2021, also eliminated the health insurer tax. Further, the Bipartisan Budget Act of 2018, or the
BBA, among other things, amended the Affordable Care Act, effective January 1, 2019, to close the coverage gap in most
Medicare drug plans, commonly referred to as the “donut hole”.  On December 14, 2018, a Texas U.S. District Court Judge
ruled  that  the  Affordable  Care  Act  is  unconstitutional  in  its  entirety  because  the  “individual  mandate”  was  repealed  by
Congress as part of the Tax Cuts and Jobs Act of 2017. Additionally, on December 18, 2019, the U.S. Court of Appeals for
the Fifth Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case
back to the District Court to determine whether the remaining provisions of the Affordable Care Act are invalid as well.
The U.S. Supreme Court is currently reviewing the case, although it is unknown when a decision will be made. Further,
although  the  U.S.  Supreme  Court  has  not  yet  ruled  on  the  constitutionality  of  the  Affordable  Care  Act,  on  January  28,
2021,  President  Biden  issued  an  executive  order  to  initiate  a  special  enrollment  period  from  February  15,  2021  through
May  15,  2021  for  purposes  of  obtaining  health  insurance  coverage  through  the  Affordable  Care  Act  marketplace.  The
executive order also instructs certain governmental agencies to review and reconsider their existing policies and rules that
limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that
include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage
through Medicaid or the Affordable Care Act. It is unclear how the Supreme Court ruling, other such litigation, and the
health care reform measures of the Biden administration will impact the Affordable Care Act and our business.

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted.
For  example,  in  August  2011,  President  Obama  signed  into  law  the  Budget  Control  Act  of  2011,  which,  among  other
things,  created  the  Joint  Select  Committee  on  Deficit  Reduction  to  recommend  to  Congress  proposals  in  spending
reductions. The Joint Select Committee on Deficit Reduction did not achieve a targeted deficit reduction of at least $1.2
trillion for fiscal years 2012 through 2021, triggering the legislation’s automatic reduction to several government programs.
This  includes  aggregate  reductions  in  Medicare  payments  to  providers  of  2%  per  fiscal  year,  which  went  into  effect
beginning on April 1, 2013 and, due to subsequent legislative amendments to the statute, including the BBA, will stay in
effect  through  2030  with  the  exception  of  a  temporary  suspension  from  May  1,  2020  through  March  31,  2021,  unless
additional Congressional action is taken. Additionally, in January 2013, the American Taxpayer Relief Act of 2012 was

16

Table of Contents

signed into law, which, among other things, reduced Medicare payments to several providers, including hospitals, cancer
treatment  centers  and  imaging  centers.  Moreover,  the  Drug  Supply  Chain  Security  Act  imposes  new  obligations  on
manufacturers  of  pharmaceutical  products  related  to  product  tracking  and  tracing.  Legislative  and  regulatory  proposals
have  been  made  to  expand  post-approval  requirements  and  restrict  sales  and  promotional  activities  for  pharmaceutical
products.

More  recently,  there  has  been  heightened  governmental  scrutiny  over  the  manner  in  which  manufacturers  set
prices for their marketed products. Such scrutiny has resulted in several recent Congressional inquiries and proposed and
enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review
the  relationship  between  pricing  and  manufacturer  patient  programs,  and  reform  government  program  reimbursement
methodologies for products.  At the federal level, the Trump administration used several means to propose or implement
drug pricing reform, including through federal budget proposals, executive orders and policy initiatives.  For example, on
July 24, 2020 and September 13, 2020, President Trump announced several executive orders related to prescription drug
pricing  that  seek  to  implement  several  of  the  administration’s  proposals.  As  a  result,  the  FDA  released  a  final  rule  on
September 24, 2020, effective November 30, 2020 providing guidance for states to build and submit importation plans for
drugs from Canada. Further, on November 20, 2020, the Department of Health and Human Services, or HHS, finalized a
regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under
Part  D,  either  directly  or  through  pharmacy  benefit  managers,  unless  the  price  reduction  is  required  by  law.  The
implementation  of  the  rule  has  been  delayed  by  the  Biden  administration  from  January  1,  2022  to  January  1,  2023  in
response to ongoing litigation. The rule also created a new safe harbor for price reductions reflected at the point-of-sale, as
well as a new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the
implementation of which have also been delayed pending review by the Biden administration until March 22, 2021. On
November 20, 2020, CMS issued an interim final rule implementing the President Trump’s Most Favored Nation executive
order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other
economically advanced countries, effective January 1, 2021. On December 28, 2020, the U.S. District Court in Northern
California issued a nationwide preliminary injunction against implementation of the interim final rule. It is unclear whether
the  Biden  administration  will  work  to  reverse  these  measures  or  pursue  similar  policy  initiatives.  At  the  state  level,
legislatures  have  become  increasingly  active  in  passing  legislation  and  implementing  regulations  designed  to  control
pharmaceutical and biological product pricing, including price or patient reimbursement constraints, 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.

The Affordable Care Act, as well as other federal and state health care reform measures that have been and may
be adopted in the future, could harm our future revenue.  Additional legislative actions may be taken in the future which
may  change  current  regulations,  guidance  and  interpretations.  Further,  it  is  also  possible  that  additional  governmental
action  is  taken  in  response  to  the  COVID-19  pandemic.  The  impact  of  such  actions  on  our  business,  if  any,  cannot
presently be determined.

The Hatch Waxman Amendments to the FDCA

Orange Book Listing

In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent whose
claims cover the applicant’s product or a method of using the product. Upon approval of a drug, each of the patents listed in
the  application  for  the  drug  is  then  published  in  the  FDA’s  Approved  Drug  Products  with  Therapeutic  Equivalence
Evaluations,  commonly  known  as  the  Orange  Book.  Drugs  listed  in  the  Orange  Book  can,  in  turn,  be  cited  by  potential
competitors in support of approval of an ANDA or an application covered by Section 505(b)(2) of the FDCA. An ANDA
provides for marketing of a drug product that has the same active ingredients, generally in the same strengths and dosage
form, as the listed drug and has been shown through pharmacokinetic, or PK, testing to be bioequivalent to the listed drug.
Drugs  approved  in  this  way  are  commonly  referred  to  as  “generic  equivalents”  to  the  listed  drug,  and  can  often  be
substituted  by  pharmacists  under  prescriptions  written  for  the  original  listed  drug.  Other  than  the  requirement  for
bioequivalence testing, ANDA applicants are generally not required to conduct, or submit results of, preclinical studies or
clinical tests to prove the safety or effectiveness of their drug product. Section 505(b)(2) applications provide for marketing
of a drug product that may have the same active ingredients as the listed drug and contains full safety and effectiveness
data  as  an  NDA,  but  at  least  some  of  this  information  comes  from  studies  not  conducted  by  or  for  the  applicant.  This
alternate  regulatory  pathway  enables  the  applicant  to  rely,  in  part,  on  the  FDA’s  findings  of  safety  and  efficacy  for  an
existing product, or published literature, in support of its application. The FDA may then approve the new drug candidate

17

Table of Contents

for  all  or  some  of  the  labeled  indications  for  which  the  referenced  product  has  been  approved,  as  well  as  for  any  new
indication sought by the 505(b)(2) applicant.

The ANDA or Section 505(b)(2) applicant is required to certify to the FDA concerning any patents listed for the
approved  product  in  the  FDA’s  Orange  Book.  Specifically,  the  applicant  must  certify  that:  (i)  the  required  patent
information has not been filed; (ii) the listed patent has expired; (iii) the listed patent has not expired, but will expire on a
particular date and approval is sought after patent expiration; or (iv) the listed patent is invalid or will not be infringed by
the  new  product.  The  ANDA  or  Section  505(b)(2)  applicant  may  also  elect  to  submit  a  statement  certifying  that  its
proposed ANDA label does not contain, or carves out, any language regarding a patented method of use rather than certify
to such listed method of use patent. If the applicant does not challenge the listed patents by filing a certification that the
listed patent is invalid or will not be infringed by the new product, the ANDA or Section 505(b)(2) application will not be
approved until all the listed patents claiming the referenced product have expired.

A certification that the new product will not infringe the already approved product’s listed patents, or that such
patents  are  invalid,  is  called  a  Paragraph  IV  certification.  If  the  ANDA  or  Section  505(b)(2)  applicant  has  provided  a
Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA
and patent holders once the ANDA or Section 505(b)(2) application has been accepted for filing by the FDA. The NDA
and  patent  holders  may  then  initiate  a  patent  infringement  lawsuit  in  response  to  the  notice  of  the  Paragraph  IV
certification.  The  filing  of  a  patent  infringement  lawsuit  within  45  days  of  the  receipt  of  a  Paragraph  IV  certification
automatically prevents the FDA from approving the ANDA or Section 505(b)(2) application until the earliest of 30 months,
expiration of the patent, settlement of the lawsuit, and a decision in the infringement case that is favorable to the ANDA or
Section 505(b)(2) applicant. This prohibition is generally referred to as the 30-month stay. Thus, approval of an ANDA or
505(b)(2) NDA could be delayed for a significant period of time depending on the patent certification the applicant makes
and the reference drug sponsor’s decision to initiate patent litigation.

The ANDA or Section 505(b)(2) application also will not be approved until any applicable non-patent exclusivity

listed in the Orange Book for the referenced product has expired.

Patent Term Extension

In the United States, after NDA approval, owners of relevant drug patents may apply for up to a five year patent
extension,  which  provides  patent  term  restoration  as  compensation  for  the  patent  term  lost  during  the  FDA  regulatory
review  process  for  the  first  permitted  commercial  marketing  of  a  drug  product.  The  Drug  Price  Competition  and  Patent
Term Restoration Act of 1984, or the Hatch-Waxman Act, permits a patent term extension of up to five years beyond the
expiration of the patent. The allowable patent term extension is calculated as half of the drug’s testing phase, which is the
time between the IND submission becoming effective and the NDA submission, and all of the review phase, which is the
time between NDA submission and approval, up to a maximum extension of five years. The time can be shortened if the
FDA  determines  that  the  applicant  did  not  pursue  approval  with  due  diligence.  Patent  extension  cannot  extend  the
remaining term of a patent beyond a total of 14 years from the date of product approval and only one patent applicable to
an approved drug may be extended.  

Similar  provisions  are  available  in  the  European  Union  and  other  foreign  jurisdictions  to  extend  the  term  of  a
patent that covers an approved drug. For example, in Japan, it may be possible to extend the patent term for up to five years
and in the European Union, it may be possible to obtain a supplementary patent certificate that would effectively extend
patent protection for up to five years.

Coverage and Reimbursement

We believe the success of our drug candidates, if approved, will depend on obtaining and maintaining coverage
and adequate reimbursement as a prescription treatment or in the absence of coverage and adequate reimbursement, on the
extent to which patients will be willing to pay out of pocket for our prescription drug products.

Third-party  payors  determine  which  prescription  drug  products  they  will  cover  and  establish  reimbursement
levels.  Reimbursement  by  a  third-party  payor  may  depend  upon  a  number  of  factors,  including:  the  third-party  payor’s
determination that a product is safe, effective, and medically necessary; appropriate for the specific patient; cost-effective;
supported  by  peer-reviewed  medical  journals  or  current  clinical  practice  guidelines;  and  whether  there  are  competitive
products, either branded or generic, and the pricing of those products.  Many private third-party payors, such as managed
care plans, manage access to drug products’ coverage partly to control costs for their plans, and may use drug formularies
and medical policies to limit their exposure.  Obtaining and maintaining favorable reimbursement can be a time-consuming

18

Table of Contents

and  expensive  process,  and  our  potential  third-party  partners  may  not  be  able  to  negotiate  or  continue  to  negotiate
reimbursement or pricing terms for our drug candidates, if approved, with third-party payors at levels that are profitable to
us, or at all.  

In addition to uncertainties surrounding coverage policies, there are periodic changes to reimbursement.  Third-
party  payors  regularly  update  reimbursement  amounts  and  also  from  time  to  time  revise  the  methodologies  used  to
determine  reimbursement  amounts.    Accordingly,  these  updates  could  impact  the  demand  for  our  drug  candidates,  if
approved. Our drug candidates, if approved, may not be considered cost effective, and government and third-party private
health  insurance  coverage  and  reimbursement  may  not  be  available  to  patients  or  sufficient  to  allow  our  potential  third-
party  partners  to  sell  our  drug  candidates,  if  approved,  on  a  competitive  and  profitable  basis.    Our  results  of  operations
could be adversely affected by the Affordable Care Act and by other health care reforms that may be enacted or adopted in
the  future.    In  addition,  increasing  emphasis  on  managed  care  in  the  United  States  will  continue  to  put  pressure  on  the
pricing of pharmaceutical products.  Cost control initiatives could decrease the price that our potential third-party partners
could receive for any of our drug candidates, if approved, and could adversely affect our profitability.  We cannot predict
how pending and future health care legislation will impact our business, and any changes in coverage and reimbursement
that further restricts coverage of our drug candidates could harm our business.

Foreign governments also have their own health care reimbursement systems, which vary significantly by country
and region, and we cannot be sure that coverage and adequate reimbursement will be made available with respect to our
drug  candidates,  if  approved,  under  any  foreign  reimbursement  system.    In  some  foreign  countries,  including  major
markets  in  the  European  Union  and  Japan,  the  pricing  of  prescription  pharmaceuticals  is  subject  to  governmental
control.  In these countries, pricing negotiations with governmental authorities can take up to 12 months or longer after the
receipt of regulatory marketing approval for a product.  To obtain reimbursement or pricing approval in some countries, we
may be required to conduct a pharmacoeconomic study that compares the cost-effectiveness of our drug candidate to other
available  therapies.    Such  pharmacoeconomic  studies  can  be  costly  and  the  results  uncertain.    Our  business  could  be
harmed if reimbursement of our drug candidates, if approved, is unavailable or limited in scope or amount or if pricing is
set at unsatisfactory levels.

Employees and Human Capital Resources

As  of  December  31,  2020,  we  had  60  total  employees,  of  which  57  were  full-time  employees.  All  of  our
employees  are  located  in  the  United  States.  None  of  our  employees  are  represented  by  a  labor  union  or  covered  by  a
collective bargaining agreement. We consider our relationship with our employees to be good.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and
integrating our existing and new employees, advisors and consultants. The principal purposes of our equity incentive plans
are to attract, retain and reward personnel through the granting of stock-based compensation awards in order to increase
stockholder value and the success of our company by motivating such individuals to perform to the best of their abilities
and achieve our objectives.

Item 1A. Risk Factors

Our  business  is  subject  to  numerous  risks.  You  should  carefully  consider  the  following  risks  and  all  other
information  contained  in  this  Annual  Report,  as  well  as  general  economic  and  business  risks,  together  with  any  other
documents we file with the SEC. If any of the following events actually occur or risks actually materialize, it could have a
material  adverse  effect  on  our  business,  operating  results  and  financial  condition  and  cause  the  trading  price  of  our
common stock to decline.

Summary of Risk Factors

● We have incurred significant losses since our inception. We expect to incur losses over the next several years

and may never achieve or maintain profitability.

● We  will  need  substantial  additional  funding  to  meet  our  financial  obligations  and  to  pursue  our  business
objectives.  If  we  are  unable  to  raise  capital  when  needed,  we  could  be  forced  to  curtail  our  planned
operations.

● Our business is dependent on the successful development of our investigational drug candidate, ATI-450.
● We have a limited history as a clinical-stage biopharmaceutical company developing and partnering our drug
candidates,  which  may  make  it  difficult  to  evaluate  the  success  of  our  business  to  date  and  to  assess  our
future viability.

● If we are unable to successfully develop our drug candidates and to pursue strategic alternatives, including
identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval  for  and/or  commercialize  our  drug  candidates,  or  experience  significant  delays  in  doing  so,  our
business will be harmed.

● Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified

personnel.

● We intend to pursue strategic alternatives, including identifying and consummating transactions with third-
party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates.
If those arrangements are not successful, we may not be able to capitalize on the market potential of these
drug candidates.

● Our business has been adversely impacted and could continue to be adversely affected by the evolving and
ongoing  COVID-19  global  pandemic  in  regions  where  we  or  third  parties  on  which  we  rely  have
manufacturing  facilities,  clinical  trial  sites  or  other  business  operations.  The  COVID-19  pandemic  could
adversely  affect  our  operations,  including  at  our  headquarters  and  at  our  clinical  trial  sites,  as  well  as  the
business or operations of our manufacturers, contract research organizations or other third parties with whom
we conduct business.

● If we are unable to obtain and maintain patent protection for our drug candidates, or if the scope of the patent
protection obtained is not sufficiently broad, our competitors could develop and commercialize technology
and drugs similar or identical to ours, and our ability to successfully pursue strategic alternatives, including
identifying  and  consummating  transactions  with  potential  third-party  partners,  to  commercialize  our
technology and drug candidates may be impaired.

● We  face  substantial  competition,  which  may  result  in  others  discovering,  developing  or  commercializing

drugs before or more successfully than we do.

Risks Related to Our Business, Our Financial Position and Capital Needs

We have incurred significant losses since our inception. We expect to incur losses over the next several years

and may never achieve or maintain profitability.

Since  inception,  we  have  incurred  significant  net  losses.  We  incurred  net  losses  of  $51.0  million  and  $161.4
million for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, we had an accumulated
deficit  of  $504.5  million.  We  have  financed  our  operations  over  the  last  several  years  primarily  from  sales  of  equity
securities and incurring indebtedness in the form of loans from commercial lenders.

We have devoted substantially all of our financial resources and efforts to the development of our drug candidates,

including preclinical studies and clinical trials, and from 2018 to October 2019, to the commercialization of our products.

20

Our  net  losses  may  fluctuate  significantly  from  quarter  to  quarter  and  year  to  year.  We  expect  to  continue  to  incur
significant expenses and operating losses in the near term as we:

● pursue strategic alternatives, including identifying and seeking to consummate transactions with third-party

partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates;

● continue  the  clinical  development  of  ATI-450,  our  MK2  inhibitor,  as  a  potential  treatment  for  moderate  to
severe  rheumatoid  arthritis  and  potentially  other  immuno-inflammatory  diseases,  and  ATI-1777,  our  “soft”
JAK inhibitor, as a potential treatment for moderate to severe atopic dermatitis;

● continue to develop our preclinical drug candidates, including ATI-2138, our ITJ inhibitor;
● continue to discover and develop additional drug candidates;
● maintain, expand and protect our intellectual property portfolio; and
● incur  legal,  accounting,  investor  relations  and  other  administrative  expenses  in  operating  as  a  public

company.  

To  become  and  remain  profitable,  we  must  succeed  in  a  range  of  challenging  activities,  including  completing
preclinical testing and clinical trials of our drug candidates and pursuing strategic alternatives, including identifying and
consummating  transactions  with  third-party  partners,  for  the  further  development  and/or  commercialization  of  our  drug
candidates, as well as discovering and developing additional drug candidates. We are in the early stages of most of these
activities. We may never succeed in these activities and, even if we do, may never earn revenue from our drug candidates
that is significant enough to achieve profitability.

For  any  of  our  drug  candidates,  our  revenue  will  be  dependent,  in  part,  upon  our  ability  to  identify  and
consummate transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize
those  drug  candidates.  Further,  we  will  be  dependent  on  our  potential  third-party  partners’  ability  to  obtain  marketing
approval  and  successfully  commercialize  the  product,  upon  the  size  of  the  markets  in  the  territories  where  marketing
approval is obtained, the accepted price for the product, and the ability to obtain coverage and reimbursement, if any. If we
fail  to  identify  and  enter  into  partnerships  with  third  parties  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize our drug candidates, any partnerships we enter into do not result in the successful development, marketing
approval  for  and  commercialization  of  our  drug  candidates,  the  number  of  addressable  patients  is  not  as  significant  as
estimated by our potential third-party partners, the indication approved by regulatory authorities is narrower than expected,
or  the  treatment  population  is  narrowed  by  competition,  physician  choice  or  treatment  guidelines,  we  may  not  earn
significant  revenue  from  agreements  with  potential  third-party  partners  for  such  drug  candidates,  even  if  the  drug
candidates are approved for marketing. 

Because of the numerous risks and uncertainties associated with drug development, we are unable to accurately
predict  the  timing  or  amount  of  expenses  or  when,  or  if,  we  will  be  able  to  achieve  profitability.  If  we  are  required  by
regulatory  authorities  to  perform  studies  in  addition  to  those  expected,  or  if  there  are  any  delays  in  the  initiation  and
completion of our clinical trials, the development of any of our drug candidates or the identification and consummation of
transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug
candidates, our expenses could increase.

Even if we 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 depress the value of our company and could impair our ability to
raise capital, expand our business, maintain our development efforts, diversify our offerings 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  will  need  substantial  additional  funding  to  meet  our  financial  obligations  and  to  pursue  our  business

objectives. If we are unable to raise capital when needed, we could be forced to curtail our planned operations. 

Identifying  potential  drug  candidates  and  conducting  preclinical  testing  and  clinical  trials  is  a  time-consuming,
expensive  and  uncertain  process  that  takes  years  to  complete,  and  we  may  never  generate  the  necessary  data  or  results
required to identify and consummate transactions with third-party partners to further develop, obtain marketing approval
for  and/or  commercialize  our  drug  candidates.  We  expect  to  incur  significant  expenses  and  operating  losses  for  the
foreseeable  future  as  we  advance  our  drug  candidates  from  discovery  through  preclinical  and  clinical  development.  In
addition, we may not be able to identify and consummate transactions with third-party partners to further develop, obtain
marketing approval for and/or commercialize our drug candidates, and our drug candidates, if approved, may not achieve

21

Table of Contents

commercial success.  Furthermore, we incur and expect to continue to incur significant costs associated with operating as a
public company, including legal, accounting, investor relations and other expenses.  

As of December 31, 2020, we had cash, cash equivalents and marketable securities of $54.1 million. We believe
that our existing cash, cash equivalents and marketable securities as of the date of this Annual Report will enable us to fund
our  operating  expenses  and  capital  expenditure  requirements  for  a  period  greater  than  12  months  from  the  date  of  this
report  based  on  our  current  operating  assumptions.  These  assumptions  may  prove  to  be  wrong,  and  we  could  use  our
available capital resources sooner than we expect. Changes may occur beyond our control that would cause us to consume
our  available  capital  before  that  time,  including  changes  in  and  progress  of  our  development  activities,  acquisitions  of
additional  products  or  drug  candidates,  and  changes  in  regulation.  Our  future  capital  requirements  will  depend  on  many
factors, including:

● the number and development requirements of the drug candidates that we may pursue;
● the  scope,  progress,  results  and  costs  of  preclinical  development,  laboratory  testing  and  conducting

preclinical and clinical trials for our drug candidates;

● the costs, timing and outcome of regulatory review of our drug candidates;
● the extent to which we in-license or acquire additional drug candidates and technologies;
● the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our

intellectual property rights and defending any intellectual property-related claims;

● the impact on the timing of our preclinical studies, on the recruitment, enrollment, conduct and timing of our

clinical trials, and on our business, due to the COVID-19 pandemic;

● our  ability  to  identify  and  consummate  transactions  with  third-party  partners  to  further  develop,  obtain
marketing approval for and/or commercialize our drug candidates, and earn revenue from such arrangements;
and

● the revenue earned from our commercial products as a result of licenses to, or partnerships with, third parties.

We will require additional capital to complete the clinical development of ATI-450 and ATI-1777, to develop our
preclinical compounds and to support our discovery efforts.  Additional funds may not be available on a timely basis, on
commercially  acceptable  terms,  or  at  all,  and  such  funds,  if  raised,  may  not  be  sufficient  to  enable  us  to  continue  to
implement our long-term business strategy. Our ability to raise additional capital may be adversely impacted by potential
worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the
United  States  and  worldwide  resulting  from  the  ongoing  COVID-19  pandemic.  If  we  are  unable  to  raise  sufficient
additional capital, we could be forced to curtail our planned operations.

Our business is dependent on the successful development of our drug candidate, ATI-450.

Our pipeline includes ATI-450, our investigational oral, novel, selective MK2 inhibitor compound, which we are
developing as a potential treatment for moderate to severe rheumatoid arthritis and potentially other immuno-inflammatory
diseases.  The  success  of  our  business  will  significantly  depend  on  our  successful  development  of  and/or  our  ability  to
pursue strategic alternatives for, including identifying and consummating transactions with third-party partners, to further
develop, obtain marketing approval for and/or commercialize, ATI-450.

Raising  additional  capital  may  cause  dilution  to  our  stockholders,  restrict  our  operations  or  require  us  to

relinquish rights to our technologies, intellectual property, potential future revenue streams or drug candidates.

Until  such  time,  if  ever,  as  we  can  earn  substantial  revenue,  we  expect  to  finance  our  cash  needs  through  a
combination  of  equity  offerings,  debt  financings  and  license  and  partnership  agreements.  To  the  extent  that  we  raise
additional capital through the sale of equity securities or convertible debt securities, your ownership interest will be diluted,
and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common
stockholder.  Debt  financing  and  preferred  equity  financing,  if  available,  may  involve  agreements  that  include  covenants
limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or
declaring dividends.

If  we  raise  additional  funds  through  partnerships,  strategic  alliances  or  marketing,  distribution  or  licensing
arrangements  with  potential  third-party  partners,  we  may  be  required  to  relinquish  valuable  rights  to  our  technologies,
intellectual property, potential future revenue streams, or drug candidates or grant licenses on terms that may not be

22

Table of Contents

favorable  to  us.  If  we  are  unable  to  raise  additional  funds  through  equity  or  debt  financings  or  other  arrangements  with
third parties when needed, we may be required to delay, limit, reduce or terminate our drug development efforts or grant
rights to third parties to develop technologies, intellectual property, or drug candidates that we would otherwise prefer to
develop ourselves.

We have a limited history as a clinical-stage biopharmaceutical company developing and partnering our drug
candidates, which may make it difficult to evaluate the success of our business to date and to assess our future viability.

Our  operations  over  the  last  several  years  have  been  largely  focused  on  raising  capital,  undertaking  preclinical
studies  and  conducting  clinical  trials,  and  acquiring  new  drug  candidates  and  related  intellectual  property.  We  have  had
limited  time  to  demonstrate  our  ability  to  successfully  develop,  manufacture  and  identify  and  consummate  transactions
with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates.
Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we
had a longer history of being a clinical-stage biopharmaceutical company focused on developing and partnering drugs. We
may  also  encounter  unforeseen  expenses,  difficulties,  complications,  delays  and  other  known  or  unknown  factors  in
achieving our business objectives.

Our  business  has  been  adversely  impacted  and  could  continue  to  be  adversely  affected  by  the  evolving  and
ongoing  COVID-19  global  pandemic  in  regions  where  we  or  third  parties  on  which  we  rely  have  manufacturing
facilities,  clinical  trial  sites  or  other  business  operations.  The  COVID-19  pandemic  could  adversely  affect  our
operations,  including  at  our  headquarters  and  at  our  clinical  trial  sites,  as  well  as  the  business  or  operations  of  our
manufacturers, contract research organizations or other third parties with whom we conduct business.

Our business has been adversely affected by the effects of the COVID-19 pandemic, which has resulted in travel
and  other  restrictions  in  order  to  reduce  the  spread  of  the  disease,  which,  among  other  things,  direct  businesses  and
governmental  agencies  to  cease  non-essential  operations  at  physical  locations,  prohibit  certain  non-essential  gatherings,
and order cessation of non-essential travel. In response to these public health directives and orders, we have implemented a
virtual operations strategy, including teleworking and other alternative work arrangements for all employees. The effects of
our  alternative  work  arrangement  policies  may  negatively  impact  productivity,  disrupt  our  business  and  delay  our
preclinical drug development and clinical trials and timelines, the magnitude of which will depend, in part, on the length
and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. These
and similar, and perhaps more severe, disruptions in our operations could negatively impact our business, operating results
and financial condition.

Quarantines, executive and similar government orders, and business shutdowns, or the perception that such orders,
shutdowns or other restrictions on the conduct of business operations could occur, related to COVID-19 or other infectious
diseases  could  impact  personnel  at  third-party  manufacturing  facilities  in  the  United  States  and  other  countries,  or  the
availability or cost of materials, which would disrupt our supply chain. Some of our third-party manufacturers which we
use for the supply of materials for our drug candidates or other materials necessary to manufacture drug product to conduct
preclinical  studies  and  clinical  trials  are  located  in  countries  affected  by  COVID-19,  and  should  they  experience
disruptions, such as temporary closures or suspension of services, we would likely experience delays in advancing these
studies and trials.

In addition, our clinical trials have been and may continue to be affected by the COVID-19 pandemic. Clinical site
initiation  and  patient  enrollment  may  be  delayed  due  to  prioritization  of  hospital  resources  toward  the  COVID-19
pandemic. Some subjects may not be able to comply with clinical trial protocols if quarantines impede patient movement
or interrupt healthcare services. Similarly, our ability to recruit and retain subjects and principal investigators and site staff
who,  as  healthcare  providers,  may  have  heightened  exposure  to  COVID-19,  may  adversely  impact  our  clinical  trial
operations. For example, due to the COVID-19 pandemic subject enrollment in our ATI-450-CAPS-201 trial was paused as
a result of which, among other reasons, we have decided to focus our efforts and resources on other immuno-inflammatory
diseases.

The  spread  of  COVID-19,  which  has  caused  a  broad  impact  globally,  may  materially  affect  us  economically.
While the potential economic impact brought by, and the duration of, the COVID-19 pandemic may be difficult to assess or
predict, the widespread pandemic could result in significant disruption of global financial markets, reducing our ability to
access capital, which could in the future negatively affect our liquidity and impact our ability to make scheduled payments
pursuant to our Loan and Security Agreement with Silicon Valley Bank, or SVB. In addition, a recession or

23

Table of Contents

market correction resulting from the further spread of COVID-19 could materially affect our business and the value of our
common stock.

The  global  COVID-19  pandemic  continues  to  rapidly  evolve.  The  extent  to  which  the  COVID-19  pandemic
impacts  our  business,  our  preclinical  and  clinical  development  and  our  regulatory  efforts  will  depend  on  future
developments that are highly uncertain and cannot be predicted, such as the geographic spread of the disease, the duration
of the outbreak, travel restrictions, quarantines, stay-at-home orders, social distancing requirements and business closures,
and supply chain and other disruptions in the United States and other countries, and the effectiveness of actions taken in the
United  States  and  other  countries  to  contain  and  treat  the  disease,  including  the  success  of  mass  vaccination  efforts.
 Accordingly, we do not yet know the full extent of the impacts on our business, our preclinical and clinical development
and regulatory activities, healthcare systems or the global economy as a whole.  However, these impacts could adversely
affect our business, financial condition, results of operations and growth prospects.

In  addition,  to  the  extent  the  ongoing  COVID-19  pandemic  adversely  affects  our  business  and  results  of

operations, it may also have the effect of heightening many of the other risks and uncertainties described herein.

We may not be able to generate sufficient cash to service our indebtedness, including the Loan and Security

Agreement with SVB.

In  March  2020,  we  entered  into  the  Loan  and  Security  Agreement  with  SVB,  pursuant  to  which  we  borrowed
$11.0 million. Our obligations under the Loan and Security Agreement are secured by substantially all of our assets except
for  our  intellectual  property,  and  restrict  us  from  encumbering  our  intellectual  property  without  SVB’s  prior  written
consent.  The  Loan  and  Security  Agreement  contains  customary  representations,  warranties  and  covenants  by  us,  which
covenants, among other things, limit our ability, subject to specified exceptions, to convey, sell, lease, transfer, assign or
otherwise dispose of our assets; engage in any business other than the businesses currently engaged in by us or reasonably
related  thereto;  liquidate  or  dissolve;  undergo  specified  change  of  control  events;  create,  incur,  assume  or  be  liable  for
indebtedness; create, incur, allow or suffer any liens on our property; pay dividends and make other restricted payments;
make investments; or enter into any material transactions with our affiliates. Our obligations under the Loan and Security
Agreement  are  subject  to  acceleration  upon  the  occurrence  of  specified  events  of  default,  including  a  material  adverse
change in our business, operations or financial condition. We may also enter into other debt agreements in the future which
may contain similar or more restrictive terms.

Our  ability  to  make  scheduled  monthly  payments  or  to  refinance  our  debt  obligations  depends  on  numerous
factors, including the amount of our cash reserves and our actual and projected financial and operating performance. These
amounts  and  our  performance  are  subject  to  certain  financial  and  business  factors,  as  well  as  prevailing  economic  and
competitive conditions, including the impact of the COVID-19 pandemic, some of which may be beyond our control. We
cannot guarantee that we will maintain a level of cash reserves or cash flows from operating activities sufficient to permit
us to pay the principal, premium, if any, and interest on our existing or future indebtedness. If our cash flows and capital
resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures,
sell assets or operations, seek additional capital or restructure or refinance our indebtedness. We cannot guarantee that we
would  be  able  to  take  any  of  these  actions,  or  that  these  actions  would  permit  us  to  meet  our  scheduled  debt  service
obligations. Failure to comply with the covenants and conditions of the Loan and Security Agreement could result in an
event of default, which could result in an acceleration of amounts due under the Loan and Security Agreement. We may not
have  sufficient  funds  or  may  be  unable  to  arrange  for  additional  financing  to  repay  our  indebtedness  or  to  make  any
accelerated payments, and SVB could seek to enforce security interests in the collateral securing such indebtedness, which
would harm our business.

Risks Related to the Development and Potential Commercialization of Our Drug Candidates

If  we  are  unable  to  successfully  develop  our  drug  candidates  and  to  pursue  strategic  alternatives,  including
identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for
and/or commercialize our drug candidates, or experience significant delays in doing so, our business will be harmed.

We  have  invested  significant  efforts  and  financial  resources  in  the  development  of  our  drug  candidates  and  the
identification  of  potential  drug  candidates.  Our  ability  to  earn  substantial  revenue  from  our  drug  candidates  will  depend
heavily  on  our  ability  to  successfully  develop  and  pursue  strategic  alternatives,  including  identifying  and  consummating
transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize these drug

24

Table of Contents

candidates.  The  success  of  any  drug  candidates  that  we  develop,  including  ATI-450,  will  depend  on  several  factors,
including:

● successful completion of preclinical studies and our clinical trials;
● successful development of manufacturing processes;
● receipt of timely approvals from applicable regulatory authorities;
● the  identification  and  consummation  of  transactions  with  third-party  partners  to  further  develop,  obtain

marketing approval for and/or commercialize our drug candidates;

● the commercial launch of our drug candidates, if approved, by a potential third-party partner;
● our  potential  third-party  partners’  ability  to  achieve  acceptance  of  our  drug  candidates,  if  approved,  by
patients, the medical community and third-party payors, and willingness of patients to pay out of pocket for
our drug candidates when third-party payor coverage and reimbursement is limited or unavailable;

● our  potential  third-party  partners’  ability  to  achieve  success  in  educating  physicians  and  patients  about  the

benefits, administration and use of our drug candidates, if approved;

● the prevalence and severity of adverse events experienced with our drug candidates;
● the  availability,  perceived  advantages,  cost,  safety  and  efficacy  of  alternative  treatments  for  the  proposed

indications of our drug candidates;

● obtaining  and  maintaining  patent,  trademark  and  trade  secret  protection  and  regulatory  exclusivity  for  our

drug candidates and otherwise protecting the intellectual property portfolio;

● maintaining  compliance  with  regulatory  requirements,  including  current  good  manufacturing  practices,  or

cGMPs;

● our potential third-party partners’ ability to compete effectively with other treatment procedures; and
● our potential third-party partners’ ability to maintain a continued acceptable safety, tolerability and efficacy

profile of our drug candidates following marketing approval.

Whether marketing approval will be granted is unpredictable and depends upon numerous factors, including the
substantial  discretion  of  the  regulatory  authorities.  Our  drug  candidates’  success  in  clinical  trials  will  not  guarantee
marketing approval. Following submission, the NDA for any drug candidate may not be accepted for substantive review, or
even  if  it  is  accepted  for  substantive  review  the  FDA  or  other  comparable  foreign  regulatory  authorities  may  require
additional  studies  or  clinical  trials,  additional  data,  or  additional  manufacturing  steps,  or  require  other  conditions  before
they  will  reconsider  or  approve  the  application,  which  could  increase  costs  and  cause  delays  in  the  marketing  approval
process  and  which  may  require  the  expenditure  of  additional  resources.  These  delays  would  also  impact  our  ability  to
identify  and  consummate  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize  our  drug  candidates.  In  addition,  the  FDA  or  other  comparable  foreign  regulatory  authorities  may  not
consider  sufficient  any  additional  required  studies,  clinical  trials,  data  or  information  that  we  perform  and  complete  or
generate, or we may decide to abandon the program.

It is possible that our drug candidates currently in development will never obtain marketing approval. If we do not
achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to
successfully pursue strategic alternatives, including identifying and consummating transactions with third-party partners, to
further develop, obtain marketing approval for and/or commercialize our drug candidates, which would harm our business.

Clinical drug development involves a lengthy and expensive process, with an uncertain outcome. We may incur
additional costs or experience delays in completing, or ultimately be unable to complete, the development of and pursue
strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop, obtain marketing approval for and/or commercialize our drug candidates.

The risk of failure for our drug candidates is high. It is impossible to predict when or if any of our drug candidates
will prove effective or safe in humans or will receive marketing approval. Before obtaining regulatory approval for the sale
of any drug candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate
the  safety  and  efficacy  of  our  drug  candidates  in  humans  for  use  in  the  target  indication.  Clinical  testing  is  expensive,
difficult to design and implement, can take many years to complete and is inherently uncertain as to outcome.

A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical testing and

early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not

25

Table of Contents

necessarily predict final results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and
analyses, and many companies that have believed their drug candidates performed satisfactorily in preclinical studies and
clinical trials have nonetheless failed to obtain marketing approval of their drugs.

We may experience numerous unforeseen events during or as a result of clinical trials that could delay or prevent
our ability to pursue strategic alternatives, including identifying and consummating transactions with third-party partners,
to further develop, obtain marketing approval for and/or commercialize our drug candidates, including:

● regulators or IRBs may not authorize us or our investigators to commence a clinical trial or conduct a clinical

trial at a prospective trial site;

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

● clinical  trials  of  our  drug  candidates  may  produce  negative  or  inconclusive  results,  including  failure  to
demonstrate statistical significance, and we may decide, or regulators may require us, to conduct additional
clinical trials or abandon drug development programs;

● the  number  of  patients  required  for  clinical  trials  of  our  drug  candidates  may  be  larger  than  we  anticipate,
enrollment  in  these  clinical  trials  may  be  slower  than  we  anticipate,  or  participants  may  drop  out  of  these
clinical trials or fail to return for post-treatment follow-up at a higher rate than we anticipate;

● the COVID-19 pandemic may impact the recruitment, enrollment, conduct and timing of our clinical trials;
● our drug candidates may have undesirable side effects or other unexpected characteristics, causing us or our

investigators, regulators or IRBs to suspend or terminate the trials;

● our  third-party  contractors  may  fail  to  comply  with  regulatory  requirements  or  meet  their  contractual

obligations to us in a timely manner, or at all;

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

● the cost of clinical trials of our drug candidates may be greater than we anticipate; and
● the supply or quality of our drug candidates or other materials necessary to conduct clinical trials of our drug

candidates may be insufficient or inadequate.

We could also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions
in which such trials are being conducted, by a data safety monitoring board 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  drug,  changes  in  governmental
regulations or administrative actions or lack of adequate funding to continue the clinical trial.  If we experience delays in
the completion of, or termination of, any clinical trial of our drug candidates, our costs will increase, our drug candidate
development process will be slowed, the commercial prospects of our drug candidates will be harmed, and our ability to
pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates  will  be  delayed.  Any  of  these
occurrences may harm our business, financial condition and prospects significantly. 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
marketing approval of our drug candidates. If we are required to conduct additional clinical trials or other testing of our
drug candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our
drug candidates or other testing, if the results of these trials or tests are not favorable or if there are safety concerns, we
may  not  be  able  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party
partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates,  and  our  potential
third-party partners may:

● be delayed in obtaining marketing approval for our drug candidates;
● not obtain marketing approval at all;
● obtain marketing approval for indications or patient populations that are not as broad as intended or desired;

26

Table of Contents

● obtain  marketing  approval  with  labeling  that  includes  significant  use  or  distribution  restrictions  or  safety

warnings;

● be subject to additional post-marketing testing requirements; or
● have the drug removed from the market after obtaining marketing approval.

Our drug development costs will also increase if we experience delays in testing. We do not know whether any of
our preclinical studies or clinical trials will begin as planned, will need to be restructured or will be completed on schedule,
or  at  all.  Significant  preclinical  study  or  clinical  trial  delays  also  could  shorten  any  periods  during  which  our  potential
third-party partners may have the exclusive right to commercialize our drug candidates or allow competitors to bring drugs
to  market  before  such  third-party  partners  do,  which  would  impact  our  ability  to  successfully  identify  and  consummate
transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug
candidates.

If  we  experience  delays  or  difficulties  in  the  enrollment  of  subjects  in  clinical  trials,  our  ability  to  pursue
strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop, obtain marketing approval for and/or commercialize our drug candidates could be delayed or prevented.

Successful  and  timely  completion  of  clinical  trials  will  require  that  we  enroll  a  sufficient  number  of  subjects.
Subject enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and
nature  of  the  patient  population.  Trials  may  be  subject  to  delays  as  a  result  of  subject  enrollment  taking  longer  than
anticipated or subject withdrawal, including as a result of factors beyond our control, such as the COVID-19 pandemic. We
may not be able to initiate or continue clinical trials for our drug candidates if we are unable to locate and enroll a sufficient
number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the
United States. We cannot predict how successful we will be at enrolling subjects in future clinical trials. Subject enrollment
is affected by other factors including:

● the eligibility criteria for the trial in question;
● the perceived risks and benefits of the drug candidate in the trial;
● the availability of drugs approved to treat the disease in the trial;
● the efforts to facilitate timely enrollment in clinical trials;
● the patient referral practices of physicians;
● the ability to monitor patients adequately during and after treatment; and
● the proximity and availability of clinical trial sites for prospective patients.

Our inability to enroll a sufficient number of subjects for clinical trials would result in significant delays and could
require us or them to abandon one or more clinical trials altogether. Enrollment delays in these clinical trials may result in
increased development costs for our drug candidates, which would cause the value of our company to decline and limit our
ability to obtain additional financing. Furthermore, we rely on and expect to continue to rely on CROs and clinical trial
sites  to  ensure  the  proper  and  timely  conduct  of  our  clinical  trials  and  we  will  have  limited  influence  over  their
performance. Any delays in completing clinical trials would delay or prevent our ability to pursue strategic alternatives,
including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our drug candidates.

Our clinical trials may fail to demonstrate the safety and efficacy of our drug candidates, or serious adverse or
unacceptable side effects may be identified during the development of our drug candidates, which could increase our
costs or necessitate the abandonment or limitation of the development of our drug candidates or prevent or delay our
ability to pursue strategic alternatives, including identifying and consummating transactions with third-party partners,
to further develop, obtain marketing approval for and/or commercialize our drug candidates.

If our drug candidates are associated with side effects in clinical trials or have characteristics that are unexpected,
our costs could increase or we may need to abandon their development or limit development to more narrow uses in which
the side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective.
The FDA or an IRB may also require that we suspend, discontinue, or limit our clinical trials based on safety information.
Such  findings  could  further  result  in  regulatory  authorities  failing  to  provide  marketing  authorization  for  our  drug
candidates. Many drug candidates that initially showed promise in early stage testing have later been found to cause side
effects that prevented further development of the drug candidate.

27

Table of Contents

Before  any  potential  third-party  partners  can  obtain  marketing  approvals  for  the  commercial  sale  of  our  drug
candidates,  we  must  demonstrate  through  lengthy,  complex  and  expensive  preclinical  testing  and  clinical  trials  that  our
drug candidates are both safe and effective for use in each target indication, and failures can occur at any stage of testing.
Clinical trials often fail to demonstrate safety and efficacy of the drug candidate studied for the target indication.

Additionally,  if  we  or  others  identify  undesirable  side  effects  caused  by  our  drugs,  a  number  of  potentially

significant negative consequences could result, including:

● we may need to abandon the development or limit the further development of our drug candidates, including

in various populations and for certain indications;  

● regulatory authorities may withdraw approval to market such product;
● regulatory authorities may require additional warnings on the labels;
● a medication guide outlining the risks of such side effects for distribution to patients may be required;
● we could be sued and held liable for harm caused to patients;
● our reputation and physician or patient acceptance of our drug candidates, if approved, may suffer; and
● our ability to pursue strategic alternatives, including identifying and consummating transactions with third-
party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates
would be harmed.

For example, we are supporting an investigator-initiated trial of ATI-450 in hospitalized patients with COVID-19.
  Although  the  COVID-19  trial  is  not  sponsored  by  us,  the  use  of  ATI-450  in  a  hospitalized  and  severely  ill  patient
population  may  be  associated  with  adverse  events  and  risks  that  could  jeopardize  our  development  of  ATI-450  in  other
populations and indications, including our trials in subjects with moderate to severe rheumatoid arthritis.

Any  of  these  events  could  prevent  us  from  pursuing  strategic  alternatives,  including  identifying  and
consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize the particular drug candidate and could significantly harm our business, results of operations and prospects.

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

From time to time, we may publicly disclose interim, topline or preliminary data from our clinical trials, such as
the preliminary topline results from our Phase 2a trial of ATI-450 in subjects with moderate to severe rheumatoid arthritis,
which are based on a preliminary analysis of then-available data, and the results and related findings and conclusions are
subject to change following a full analysis of all data related to the particular trial. We also make assumptions, estimations,
calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully
and carefully evaluate all data. In addition, we may report preliminary analyses of only certain endpoints rather than all
endpoints. As a result, the interim, topline or preliminary results that we report may differ from future results of the same
trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully
evaluated.  Topline  data  also  remain  subject  to  audit  and  verification  procedures  that  may  result  in  the  final  data  being
materially different from the preliminary data we previously published. As a result, interim, topline and preliminary data
should be viewed with caution until the final data are available. We may also disclose interim data from our clinical trials.
Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may
materially change as subject enrollment continues and more subject data become available. Adverse differences between
interim, topline or preliminary data and final data could significantly harm our reputation and business prospects. Further,
disclosure of interim, topline or preliminary data by us or by our competitors could result in volatility in the price of our
common stock.

Further,  others,  including  regulatory  agencies,  may  not  accept  or  agree  with  our  assumptions,  estimates,
calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the
potential  of  the  particular  program,  the  likelihood  of  marketing  approval  or  commercialization  of  the  particular  drug
candidate, any approved product, and our company in general. In addition, the information we choose to publicly disclose
regarding a particular study or clinical trial is derived from information that is typically extensive, and you or others may
not agree with what we determine is material or otherwise appropriate information to include in our disclosure, and any

28

Table of Contents

information  we  determine  not  to  disclose  may  ultimately  be  deemed  significant  with  respect  to  future  decisions,
conclusions, views, activities or otherwise regarding a particular program, drug candidate or our business.

If  the  interim,  topline  or  preliminary  data  that  we  report  differ  from  actual  results,  or  if  others,  including
regulatory  authorities,  disagree  with  the  conclusions  reached,  our  ability  to  pursue  strategic  alternatives,  including
identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for
and/or commercialize our drug candidates may be harmed, which could harm our business, operating results, prospects or
financial condition.

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

As  drug  candidates  are  developed  through  preclinical  studies  to  late-stage  clinical  trials  towards  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,  and  may  also  require  additional  testing,  FDA  notification  or  FDA
approval.  Any of these changes could cause our drug candidates to perform differently and affect the results of planned
clinical trials or other future clinical trials conducted with the altered materials.  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 drug candidates and jeopardize our ability to pursue strategic alternatives, including identifying
and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize our drug candidates.

We may not be successful in our efforts to increase our pipeline of drug candidates, including by in-licensing

or acquiring additional drug candidates.

A key element of our strategy is to build and expand our pipeline of drug candidates. To build our pipeline, we
may seek to in-license or acquire additional drug candidates. We may not be able to identify or develop drug candidates
that  are  safe,  tolerable  and  effective.  Even  if  we  are  successful  in  continuing  to  build  our  pipeline,  the  potential  drug
candidates  that  we  develop,  in-license  or  acquire  may  not  be  suitable  for  clinical  development,  including  as  a  result  of
being shown to have harmful side effects or other characteristics that indicate that they are unlikely to be drugs that will
receive marketing approval and achieve market acceptance.

We may expend our limited resources to pursue a particular drug candidate or indication and fail to capitalize

on drug candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because  we  have  limited  financial  and  management  resources,  we  focus  on  development  programs  and  drug
candidates  that  we  identify  for  specific  indications.  As  such,  we  are  currently  primarily  focused  on  the  development  of
ATI-450 as a potential treatment for moderate to severe rheumatoid arthritis and potentially other immuno-inflammatory
diseases  and  ATI-1777  as  a  potential  treatment  for  moderate  to  severe  atopic  dermatitis.   As  a  result,  we  may  forego  or
delay  pursuit  of  opportunities  with  other  drug  candidates  or  for  other  indications  that  later  prove  to  have  greater
commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial drugs or
profitable market opportunities. Our spending on current and future development programs and drug candidates for specific
indications  may  not  yield  any  commercially  viable  drugs.  If  we  do  not  accurately  evaluate  the  commercial  potential  or
target market for a particular drug candidate, we may relinquish valuable rights to that drug candidate through partnerships,
licensing or other arrangements in cases in which it would have been more advantageous for us to retain sole development
and commercialization rights to such drug candidate.

For any of our drug candidates that receive marketing approval, our potential third-party partners 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.

For any of our drug candidates that receive marketing approval, our potential third-party partners may fail to gain
sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. If such third-
party partners fail to obtain an adequate level of acceptance for our drug candidates, we may not earn significant revenue

29

Table of Contents

and we may not become profitable. The degree of market acceptance of any drug candidate, if approved, will depend on a
number of factors, including:

● the efficacy, safety and potential advantages compared to alternative treatments;
● our potential third-party partners’ ability to offer the products for sale at competitive prices;
● the convenience and ease of administration compared to alternative treatments;
● the  willingness  of  the  target  patient  population  to  try  new  treatments  and  of  physicians  to  prescribe  these

treatments;

● the ability of our potential third-party partners to retain a sales force;
● the strength of our potential third-party partners’ marketing and distribution support;
● the availability of third-party payor coverage and adequate reimbursement or the willingness of patients to

pay for these products;

● the prevalence and severity of any side effects; and
● any restrictions on the use of our products together with other medications.

We face substantial competition, which may result in others discovering, developing or commercializing drugs

before or more successfully than we do.

The  development  and  commercialization  of  new  drugs  is  highly  competitive.  We  will  face  competition  with
respect to any drug candidates that we may seek to develop or through our potential third-party partners, commercialize, in
the  future,  from  many  different  sources,  including  major  pharmaceutical,  biotechnology  and  specialty  pharmaceutical
companies, academic institutions and governmental agencies and public and private research institutions.

With  respect  to  ATI-450  as  a  potential  treatment  for  moderate  to  severe  rheumatoid  arthritis,  there  are  several
different  types  of  therapies  in  the  rheumatoid  arthritis  market.  Medications  for  the  treatment  of  rheumatoid  arthritis
currently fall into two categories: drugs that ease symptoms such as nonsteroidal anti-inflammatory drugs and drugs that
slow  disease  activity.  Drugs  that  slow  disease  activity  include  corticosteroids  and  DMARDs.  Disease-modifying  drugs
include conventional DMARDs such as methotrexate, sulfasalazine, leflunomide, hydroxychloroquine, biologic DMARDs
(monoclonal antibodies which inhibit targets such as TNF, IL1, IL6 and costimulatory signaling mechanisms), and targeted
synthetic  DMARDs  such  as  JAK  inhibitors.  These  types  of  drugs  are  produced  and  sold  by  large  pharmaceutical
companies,  including  AbbVie,  Amgen,  Bristol  Myers  Squibb,  Eli  Lilly,  Johnson  &  Johnson,  Merck,  Pfizer,  and  Roche,
among  others.  In  addition,  we  are  aware  of  a  number  of  companies  developing  and  conducting  clinical  trials  for
investigational drug candidates, including biosimilars, that, if approved, could compete with ATI-450, if approved, for the
treatment of rheumatoid arthritis.

With  respect  to  ATI-1777  as  a  potential  treatment  for  moderate  to  severe  atopic  dermatitis,  there  are  several
different types of therapies in the atopic dermatitis market, such as biologics, oral and topical corticosteroids, injectable and
oral  methotrexate  products,  oral  and  topical  calcineurin  inhibitors,  oral  mycophenolate  products,  other  JAK  inhibitors,
other oral antibiotics and antihistamines and phototherapy. There are also several prescription, non-prescription and OTC
topical products, including PDE4 inhibitors, utilized to treat atopic dermatitis. These types of drugs are produced and sold
by large pharmaceutical companies, including Sanofi and Regeneron Pharmaceuticals, Inc., and Pfizer. In addition, we are
aware of a number of companies including large pharmaceutical companies, such as AbbVie, Eli Lilly, Novartis, Incyte,
Pfizer and LEO Pharma A/S developing and conducting clinical trials for investigational drug candidates, that, if approved,
could compete with ATI-1777, if approved, for the treatment of atopic dermatitis.

The  commercial  opportunity  for  our  drug  candidates,  if  approved,  could  be  reduced  or  eliminated  if  our
competitors develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more
convenient  or  are  less  expensive  than  a  drug  that  we  may  develop.  Our  competitors  also  may  obtain  FDA  or  other
regulatory approval for their drugs more rapidly than our potential third-party partners’ may obtain approval for our drug
candidates, which could result in our competitors establishing a strong market position before our drug candidates are able
to enter the market.

Many of the companies against which we are competing, or against which we may compete in the future, have
significantly  greater  financial  resources  and  expertise  in  research  and  development,  manufacturing,  and  preclinical  and
clinical development than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result
in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies

30

Table of Contents

may  also  prove  to  be  significant  competitors,  particularly  through  collaborative  arrangements  with  large  and  established
companies.  These  competitors  also  compete  with  us  in  recruiting  and  retaining  qualified  scientific  and  management
personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies
complementary to, or that may be necessary for, our development programs.

The  success  of  our  drug  candidates,  if  approved,  will  depend  significantly  on  coverage  and  adequate

reimbursement or the willingness of patients to pay for these products.

We believe the success of our drug candidates, if approved, will depend on obtaining and maintaining coverage
and adequate reimbursement as a prescription treatment or in the absence of coverage and adequate reimbursement, on the
extent to which patients will be willing to pay out of pocket for these prescription drug products.

Third-party  payors  determine  which  prescription  drug  products  they  will  cover  and  establish  reimbursement
levels.  Reimbursement  by  a  third-party  payor  may  depend  upon  a  number  of  factors,  including:  the  third-party  payor’s
determination that a product is safe, effective, and medically necessary; appropriate for the specific patient; cost-effective;
supported  by  peer-reviewed  medical  journals  or  current  clinical  practice  guidelines;  and  whether  there  are  competitive
products, either branded or generic, and the pricing of those products.  Many private third-party payors, such as managed
care plans, manage access to drug products’ coverage partly to control costs for their plans, and may use drug formularies
and medical policies to limit their exposure.  Obtaining and maintaining favorable reimbursement can be a time-consuming
and  expensive  process,  and  our  potential  third-party  partners  may  not  be  able  to  negotiate  or  continue  to  negotiate
reimbursement or pricing terms for our products with third-party payors at levels that are profitable to us, or at all.  

In addition to uncertainties surrounding coverage policies, there are periodic changes to reimbursement.  Third-
party  payors  regularly  update  reimbursement  amounts  and  also  from  time  to  time  revise  the  methodologies  used  to
determine  reimbursement  amounts.    Accordingly,  these  updates  could  impact  the  demand  for  our  drug  candidates,  if
approved. Our drug candidates, if approved, may not be considered cost effective, and government and third-party private
health  insurance  coverage  and  reimbursement  may  not  be  available  to  patients  or  sufficient  to  allow  our  potential  third-
party  partners  to  sell  our  drug  candidates,  if  approved,  on  a  competitive  and  profitable  basis.    Our  results  of  operations
could be adversely affected by the Affordable Care Act and by other health care legislative reforms that may be enacted or
adopted in the future.  In addition, increasing emphasis on managed care in the United States will continue to put pressure
on the pricing of pharmaceutical products.  Cost control initiatives could decrease the price that our potential third-party
partners could receive for any of our drug candidates, if approved, and could adversely affect our profitability.  We cannot
predict  how  pending  and  future  health  care  legislation  will  impact  our  business,  and  any  changes  in  coverage  and
reimbursement that further restricts coverage of our drug candidates could harm our business.

Foreign governments also have their own healthcare reimbursement systems, which vary significantly by country
and region, and we cannot be sure that coverage and adequate reimbursement will be made available with respect to our
drug  candidates,  if  approved,  under  any  foreign  reimbursement  system.    In  some  foreign  countries,  including  major
markets  in  the  European  Union  and  Japan,  the  pricing  of  prescription  pharmaceuticals  is  subject  to  governmental
control.  In these countries, pricing negotiations with governmental authorities can take up to 12 months or longer after the
receipt of regulatory marketing approval for a product.  To obtain reimbursement or pricing approval in some countries, we
may be required to conduct a pharmacoeconomic study that compares the cost-effectiveness of our drug candidate to other
available  therapies.    Such  pharmacoeconomic  studies  can  be  costly  and  the  results  uncertain.    Our  business  could  be
harmed if reimbursement of our drug candidates, if approved, is unavailable or limited in scope or amount or if pricing is
set at unsatisfactory levels.

Product  liability  lawsuits  against  us  could  cause  us  to  incur  substantial  liabilities  and  to  limit
commercialization of any of our drug candidates that we may develop and are commercialized by our potential third-
party partners or impact any commercial products that we have previously sold or are being sold by third-party partners.

We  face  an  inherent  risk  of  product  liability  exposure  related  to  the  testing  of  our  drug  candidates  in  human
clinical trials and an even greater risk relating to any of our commercial products that we have previously sold or are being
sold by third-party partners. If we cannot successfully defend ourselves against claims that our commercial products that

31

Table of Contents

we  have  previously  sold  or  are  being  sold  by  third-party  partners,  or  drug  candidates,  caused  injuries,  we  will  incur
substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:

● decreased demand for any drug candidates that we may develop and, if approved, are commercialized by our

potential third-party partners;

● injury to our reputation and significant negative media attention;
● withdrawal of clinical trial participants;
● significant costs to defend the related litigation;
● substantial monetary awards paid to trial participants or patients;
● loss of revenue;
● reduced resources of our management to pursue our business strategy; and
● our inability to pursue strategic alternatives, including identifying and consummating transactions with third-
party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates.

We currently hold $10 million in product liability insurance coverage in the aggregate, with a per incident limit of
$10  million,  which  may  not  be  adequate  to  cover  all  liabilities  that  we  may  incur.  Insurance  coverage  is  increasingly
expensive. We may need to increase our insurance coverage and 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.

Risks Related to Our Dependence on Third Parties

We  rely  on  third  parties  to  conduct  clinical  trials  for  our  drug  candidates,  and  those  third  parties  may  not

perform satisfactorily, including failing to meet deadlines for the completion of such trials.

We engage CROs to conduct clinical trials of our drug candidates. We expect to continue to rely on third parties,
such  as  clinical  data  management  organizations,  medical  institutions  and  clinical  investigators,  to  conduct  those  clinical
trials. If any of our relationships with these third parties terminate, we may not be able to timely enter into arrangements
with  alternative  third  parties  or  to  do  so  on  commercially  reasonable  terms,  if  at  all.  In  addition,  any  third  parties
conducting our clinical trials will not be our employees, and except for remedies available to us under our agreements with
such third parties, we cannot control whether or not they devote sufficient time and resources to our clinical programs. If
these third parties do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they
need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere
to  our  clinical  protocols,  regulatory  requirements  or  for  other  reasons,  our  clinical  trials  may  be  extended,  delayed  or
terminated and we may not be able to identify and  consummate transactions with third-party partners to further develop,
obtain marketing approval for and/or commercialize our drug candidates. Consequently, our results of operations and the
commercial prospects for our drug candidates would be harmed, our costs could increase substantially and our ability to
earn revenue from those partnerships could be delayed significantly.

Switching or adding CROs involves substantial cost and requires management time and focus. In addition, there is
a natural transition period when a new CRO commences work. As a result, delays occur, which can materially impact our
ability to meet our desired clinical development timelines. Though we intend to carefully manage our relationships with
our CROs, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or
challenges will not have a material adverse impact on our business, financial condition and prospects.

We rely on these parties for execution of our preclinical studies and clinical trials, and generally do not control
their activities. Our reliance on these third parties for research and development activities will reduce our control over these
activities but will not relieve us of our responsibilities. For example, we will remain responsible for ensuring that each of
our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the
FDA  requires  us  to  comply  with  standards,  commonly  referred  to  as  good  clinical  practices,  or  GCPs,  for  conducting,
recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and
that  the  rights,  integrity  and  confidentiality  of  trial  participants  are  protected.  We  also  are  required  to  register  ongoing
clinical  trials  and  post  the  results  of  completed  clinical  trials  on  a  government-sponsored  database,  ClinicalTrials.gov,
within specified timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions. If we or
any  of  our  CROs  fail  to  comply  with  applicable  GCPs,  the  clinical  data  generated  in  our  clinical  trials  may  be  deemed
unreliable  and  the  FDA  or  comparable  foreign  regulatory  authorities  may  require  us  to  perform  additional  clinical  trials
before approving marketing applications. We cannot assure you that upon inspection by a given regulatory

32

Table of Contents

authority,  such  regulatory  authority  will  determine  that  any  of  our  clinical  trials  complies  with  GCP  regulations.  In
addition, our clinical trials must be conducted with drug product produced under cGMP regulations. Our failure to comply
with these regulations may require us to repeat clinical trials, which would delay the marketing approval process for our
potential third-party partners.

We also rely on other third parties to store and distribute drug supplies for our clinical trials. Any performance
failure  on  the  part  of  our  distributors  could  delay  clinical  development  or  marketing  approval  of  our  drug  candidates  or
commercialization of our drug candidates, if approved, producing additional losses and depriving us of potential revenue.

We  contract  with  third  parties  for  the  manufacture  and  supply  of  our  drug  candidates  for  preclinical  and
clinical testing. This reliance on third parties increases the risk that we will not have sufficient quantities of our drug
candidates or such quantities at an acceptable cost, which could delay, prevent or impair our development efforts.

We do not have any manufacturing facilities. We currently rely, and expect to continue to rely, on third parties for
the  manufacture  and  supply  of  our  drug  candidates  for  preclinical  and  clinical  testing.  This  reliance  on  third  parties
increases  the  risk  that  we  will  not  have  sufficient  quantities  of  our  drug  candidates  at  an  acceptable  cost  and/or  quality,
which could delay, prevent or impair our ability to timely conduct our clinical trials or our other development efforts.

The  facilities  used  by  our  contract  manufacturers  to  manufacture  our  drug  candidates  must  be  approved  by  the
FDA  or  comparable  foreign  regulatory  authorities  pursuant  to  inspections  that  will  be  conducted  after  the  NDA  or
comparable  marketing  application  is  submitted  to  the  FDA  or  other  regulatory  authority.  We  do  not  have  control  over  a
supplier’s  or  manufacturer’s  compliance  with  laws,  regulations  and  applicable  cGMP  standards  and  other  laws  and
regulations,  such  as  those  related  to  environmental  health  and  safety  matters.  If  our  contract  manufacturers  cannot
successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or
others, they will not be able to secure and maintain regulatory approval for their manufacturing facilities. In addition, we
have no control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and
qualified  personnel.  If  the  FDA  or  a  comparable  foreign  regulatory  authority  does  not  approve  these  facilities  for  the
manufacture  of  our  drug  candidates  or  if  it  withdraws  any  such  approval  in  the  future,  we  may  need  to  find  alternative
manufacturing facilities, which could significantly impact our ability to develop, and identify and consummate transactions
with third-party partners to further develop, obtain marketing approval for and/or commercialize, our drug candidates.

We may be unable to establish any agreements with future third-party manufacturers or do so on acceptable terms.
Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails
additional risks, including:

● reliance on the third party for regulatory compliance and quality assurance;
● the possible breach of the manufacturing agreement by the third party;
● the possible misappropriation of our proprietary information, including our trade secrets and know-how;
● the possible increase in costs by our third-party suppliers for the active pharmaceutical ingredients for our

drug candidates; and

● the  possible  termination  or  nonrenewal  of  the  agreement  by  the  third  party  at  a  time  that  is  costly  or

inconvenient for us.

Third-party manufacturers may not be able to comply with cGMP regulations or similar regulatory requirements
outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations
could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension
or  withdrawal  of  approvals,  license  revocation,  seizures  or  recalls  of  products,  operating  restrictions  and  criminal
prosecutions, any of which could significantly and adversely affect supplies of our drug candidates. 

Our drug candidates may compete with other products and drug candidates for access to manufacturing facilities.
There  are  a  limited  number  of  manufacturers  that  operate  under  cGMP  regulations  and  that  might  be  capable  of
manufacturing  for  us.  Any  performance  failure  on  the  part  of  our  existing  or  future  manufacturers  could  delay  clinical
development or marketing approval of our drug candidates.

If  our  current  contract  manufacturers  cannot  perform  as  agreed,  we  may  be  required  to  replace  such

manufacturers. We may incur added costs and delays in identifying and qualifying any such replacement. We do not

33

Table of Contents

currently  have  arrangements  in  place  for  redundant  supply  or  a  second  source  for  the  active  pharmaceutical  ingredients
and/or drug product for our drug candidates.

We expect to continue to depend on third-party contract manufacturers for the foreseeable future. Our current and
anticipated  future  dependence  upon  others  for  the  manufacture  of  our  drug  candidates  may  adversely  affect  our  future
profit  margins  and  our  ability  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with
third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates  on  a
timely and competitive basis.

We  intend  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-
party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates.  If  those
arrangements are not successful, we may not be able to capitalize on the market potential of these drug candidates.

We intend to pursue strategic alternatives, including identifying and consummating transactions with third-party
partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates. Our likely partners
for  any  such  arrangements  include  large  and  mid-size  pharmaceutical  companies,  regional  and  national  pharmaceutical
companies and biotechnology companies. If we do enter into any such arrangements with any third parties, we will likely
have  limited  control  over  the  amount  and  timing  of  resources  that  our  partners  dedicate  to  the  development  or
commercialization  of  our  drug  candidates.  Our  ability  to  earn  revenue  from  these  arrangements  will  depend  on  our
partners’ abilities to successfully perform the functions assigned to them in these arrangements.

Partnerships involving our drug candidates would pose the following risks to us:

● partners  have  significant  discretion  in  determining  the  efforts  and  resources  that  they  will  apply  to  these

arrangements;

● partners may not perform their obligations as expected;
● partners may not pursue development, marketing approval or commercialization of any drug candidates that
achieve  marketing  approval  or  may  elect  not  to  continue  or  renew  development  or  commercialization
programs  based  on  clinical  trial  results,  changes  in  the  partners’  strategic  focus  or  available  funding,  or
external factors, such as an acquisition, that divert resources or create competing priorities;

● partners may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial
or  abandon  a  drug  candidate,  repeat  or  conduct  new  clinical  trials  or  require  a  new  formulation  of  a  drug
candidate for clinical testing;

● partners  could  independently  develop,  or  develop  with  third  parties,  products  that  compete  directly  or
indirectly  with  our  drug  candidates  if  the  partners  believe  that  competitive  products  are  more  likely  to  be
successfully  developed  or  can  be  commercialized  under  terms  that  are  more  economically  attractive  than
ours;

● drug candidates discovered in collaboration with us may be viewed by our collaborators as competitive with
their  own  products  or  drug  candidates,  which  may  cause  our  partners  to  cease  to  devote  resources  to  the
development and/or commercialization of our drug candidates, if approved;

● a partner with marketing and distribution rights to one or more of our drug candidates that achieve marketing
approval may not commit sufficient resources to the marketing and distribution of such drug candidates;
● disagreements  with  partners,  including  disagreements  over  proprietary  rights,  contract  interpretation  or  the
preferred  course  of  development  or  commercialization,  might  cause  delays  or  termination  of  the  research,
development  or  commercialization  of  drug  candidates,  might  lead  to  additional  responsibilities  for  us  with
respect to drug candidates, or might result in litigation or arbitration, any of which would be time-consuming
and expensive;

● partners may not properly maintain or defend our or their intellectual property rights or may use our or their
proprietary  information  in  such  a  way  as  to  invite  litigation  that  could  jeopardize  or  invalidate  such
intellectual property or proprietary information or expose us to potential litigation;

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

potential liability; and

● partnerships may be terminated for the convenience of the partner and, if terminated, we could be required to
raise  additional  capital  to  pursue  further  development  and/or  commercialization  of  the  applicable  drug
candidates.

34

Table of Contents

Partnership  agreements  may  not  lead  to  development,  marketing  approval  or  commercialization  of  drug
candidates in the most efficient manner or at all. If a present or future partner of ours were to be involved in a business
combination,  the  continued  pursuit  and  emphasis  on  our  drug  development  or  commercialization  program  could  be
delayed, diminished or terminated. 

If  we  are  not  able  to  establish  partnerships,  we  may  have  to  alter  our  development  and  commercialization

plans.

Our drug development programs for our drug candidates will require substantial additional capital. We intend to
partner  with  pharmaceutical  and  biotechnology  companies  for  the  further  development  and/or  commercialization  of  our
drug candidates.

We face significant competition in seeking appropriate partners. Whether we reach a definitive agreement for a
partnership will depend, among other things, upon our assessment of the partner’s resources and expertise, the terms and
conditions of the proposed arrangement and the proposed partner’s evaluation of a number of factors. Those factors may
include  the  design  or  results  of  clinical  trials,  the  likelihood  of  approval  by  the  FDA  or  similar  regulatory  authorities
outside the United States, the potential market for the subject drug candidate, the costs and complexities of manufacturing
and  delivering  such  drug  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  partner  may  also  consider  alternative  drug
candidates or technologies for similar indications that may be available to partner on and whether such a partnership could
be more attractive than the one with us for our drug candidate. Partnerships are complex and time-consuming to negotiate
and  document.  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 partners.

We may not be able to negotiate partnerships 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 such drug candidate, or reduce or delay its development program or one
or more of our other development programs, 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  drug  candidates  or  bring  them  to  market  and
generate revenue.

We  may  not  have  access  to  all  information  regarding  our  drug  candidates  that  are  subject  to  partnership
agreements.  Consequently,  our  ability  to  inform  our  stockholders  about  the  status  of  our  drug  candidates  that  are
subject to these agreements, and our ability to make business and operational decisions, may be limited.

We  may  not  have  access  to  all  information  regarding  our  drug  candidates  that  may  become  subject  to  agreements
with  partners,  including  potentially  material  information  about  clinical  trial  design,  execution  and  timing,  safety  and
efficacy,  clinical  trial  results,  regulatory  affairs,  manufacturing,  marketing,  sales  and  other  areas  known  by  our  potential
partners.  In  addition,  we  may  have  confidentiality  obligations  under  our  agreements  with  such  partners.  Therefore,  our
ability to keep our stockholders informed about the status of our drug candidates will be limited by the degree to which our
partners keep us informed and by the degree to which our partners allow us to disclose information to the public or provide
such information to the public themselves. If our partners do not timely inform us about the status of our drug candidates
that are the subject of the partnership, we may make operational and investment decisions that we would not have made
had we been fully informed, which may have an adverse impact on our business, prospects, financial condition and results
of operations.

Our sublease could terminate if the master lease is terminated for any reason, thus terminating our rights to

our corporate headquarters.

We sublease space for our corporate headquarters.  While the term of the sublease extends until October 2023, if

for any reason the master lease is terminated or expires prior to October 2023, our sublease will also automatically
terminate.  In such an event, we would need to obtain a new direct lease with the master landlord or negotiate and enter
into a new lease for office space at a different location, which we may not be able to do on commercially reasonable terms,
if at all.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain patent protection for our drug candidates, or if the scope of the patent
protection  obtained  is  not  sufficiently  broad,  our  competitors  could  develop  and  commercialize  technology  and  drugs
similar  or  identical  to  ours,  and  ability  to  successfully  identify  a  potential  third-party  partner  to  commercialize  our
technology and drug candidates may be impaired.

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 drug candidates. We seek to protect our proprietary position by filing patent applications
in the United States and abroad related to our drug candidates. 

The patent prosecution process is expensive and time-consuming, however, and we may not be able to file and
prosecute 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 development output before it is too late to obtain patent protection. We may
not  have  the  right  to  control  the  preparation,  filing  and  prosecution  of  patent  applications,  or  to  maintain  the  rights  to
patents licensed to third parties. Therefore, these patents and applications may not be prosecuted and enforced in a manner
consistent with the best interests of our business.

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. In addition, the laws of
foreign countries may not protect our rights to the same extent as the laws of the United States or vice versa. For example,
European  patent  law  restricts  the  patentability  of  methods  of  treatment  of  the  human  body  more  than  U.S.  law  does.
Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the
United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all.
Therefore, we cannot know with certainty whether we or our licensors were the first to make the inventions claimed in our
patents  or  pending  patent  applications,  or  that  we  or  our  licensors  were  the  first  to  file  for  patent  protection  of  such
inventions. 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
drug candidates, in whole or in part, or which effectively prevent others from commercializing competitive technologies
and drug candidates. Changes in either the patent laws or interpretation of the patent laws in the United States and other
countries may diminish the value of our patents or narrow the scope of our patent protection.

Moreover, we may be subject to a third-party preissuance submission of prior art to the U.S. Patent and Trademark
Office, or USPTO, or become involved in opposition, derivation, reexamination, inter partes review, post-grant review or
interference proceedings challenging our patent rights or the patent rights of others. An adverse determination in any such
submission,  proceeding  or  litigation  could  reduce  the  scope  of,  or  invalidate,  our  patent  rights,  allow  third  parties  to
commercialize  our  technology  or  drug  candidates  and  compete  directly  with  us,  without  payment  to  us,  or  result  in  the
inability of our potential third-party partners to manufacture or commercialize our drug candidates without infringing third-
party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications that
we  own  or  license  is  threatened,  it  could  dissuade  companies  from  partnering  with  us  to  license,  develop  and/or
commercialize our drug candidates. 

Even  if  our  patent  applications  that  we  own  or  license  issue  as  patents,  they  may  not  issue  in  a  form  that  will
provide  us  with  any  meaningful  protection,  prevent  competitors  from  competing  with  us  or  our  potential  third-party
partners or otherwise provide us or our potential third-party partners with any competitive advantage. Competitors may be
able to circumvent our patents by developing similar or alternative technologies or drugs in a non-infringing manner.

In addition, the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and
our patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in
loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or
in part, which could limit the ability to stop others from using or commercializing similar or identical technology and drug
candidates, or limit the duration of the patent protection of our technology and drug candidates. Our issued U.S. patents
covering  our  lead  inhibitor  of  the  MK2  signaling  pathway,  ATI-450,  expire  in  2034  and  other  issued  patents  covering
different MK2 signaling pathway inhibitors expire in 2031 and 2032. We currently do not have any patents issued directed
to our lead “soft” JAK inhibitor, ATI-1777, but any claims that may issue would expire in 2038. Our issued patent covering
other novel “soft” JAK inhibitors expires in 2038.  We currently do not have any patents issued directed to our lead ITK
inhibitor, ATI-2138, but any claims that may issue would expire in 2039.  Our issued patents covering other

36

Table of Contents

novel inhibitors of ITK expire between 2035 and 2038. Given the amount of time required for the development, testing and
regulatory  review  of  new  drug  candidates,  patents  protecting  such  candidates  might  expire  before  or  shortly  after  such
candidates  are  commercialized.  As  a  result,  our  patent  portfolio  may  not  provide  us  or  our  potential  third-party  partners
with sufficient rights to exclude others from commercializing drugs similar or identical to ours.

We  may  become  involved  in  lawsuits  to  protect  or  enforce  our  patents  or  other  intellectual  property,  which
could  be  expensive,  time-consuming  and  unsuccessful.  Further,  our  issued  patents  could  be  found  invalid  or
unenforceable if challenged in court.

Competitors  may  infringe  our  issued  patents  or  other  intellectual  property.  Our  pending  applications  cannot  be
enforced against third parties practicing the technology claimed in such applications unless and until a patent issues from
such applications. To counter infringement or unauthorized use, we may be required to file infringement claims, which can
be expensive and time-consuming. Any claims we assert against perceived infringers could provoke these parties to assert
counterclaims against us alleging that we infringe their patents or that our patents are invalid or unenforceable. Grounds for
a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty,
obviousness,  non-enablement  or  insufficient  written  description.  Grounds  for  an  unenforceability  assertion  could  be  an
allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a
misleading  statement  during  prosecution.  Third  parties  may  also  raise  similar  claims  before  the  USPTO,  in  post-grant
proceedings  such  as  ex  parte  reexaminations,  inter  partes  review,  or  post-grant  review,  or  oppositions  or  similar
administrative proceedings outside the United States, in parallel with litigation or, even outside the context of litigation.
The  outcome  following  legal  assertions  of  invalidity  and  unenforceability  is  unpredictable.  With  respect  to  the  validity
question, for example, we cannot be certain that there is no invalidating prior art of which we and the patent examiner were
unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would
lose at least part, and perhaps all, of the patent protection on our drug candidates. Such a loss of patent protection would
harm our business. 

In such a proceeding, a court or administrative board may decide that a patent of ours is invalid or unenforceable,
in whole or in part, construe the patent’s claims narrowly or refuse to stop the other party from using the technology at
issue on the grounds that our patents do not cover the technology. An adverse result in any such proceeding could put one
or  more  of  our  patents  at  risk  of  being  invalidated  or  interpreted  narrowly.  We  may  find  it  impractical  or  undesirable  to
enforce our intellectual property against some third parties. 

Interference proceedings provoked by third parties or brought by us or declared by the USPTO may be necessary
to determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome could
require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business
could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. 

Furthermore,  because  of  the  substantial  amount  of  discovery  required  in  connection  with  intellectual  property
litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of
litigation.

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

Filing, prosecuting and defending patents on our drug candidates in all countries throughout the world would be
prohibitively  expensive,  and  our  intellectual  property  rights  in  some  countries  outside  the  United  States  can  be  less
extensive  than  those  in  the  United  States.  For  example,  our  lead  inhibitor  of  the  MK2  signaling  pathway,  ATI-450,  is
currently  covered  by  patents  and  applications  in  the  United  States,  European  Union  and  other  foreign  markets.    We
currently  do  not  have  any  patents  issued  directed  to  our  lead  “soft”  JAK  inhibitor,  ATI-1777,  or  our  lead  ITK  inhibitor,
ATI-2138, rather we have pending applications in the United States, European Union and other foreign markets directed to
each of ATI-1777 and ATI-2138.

Many companies have encountered significant problems in protecting and defending intellectual property rights in
foreign jurisdictions. The legal systems of some countries do not favor the enforcement of patents and other intellectual
property protection, which could make it difficult for us to stop the infringement of our patents 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

37

Table of Contents

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. 

Many  countries,  including  European  Union  countries,  India,  Japan  and  China,  have  compulsory  licensing  laws
under  which  a  patent  owner  may  be  compelled  under  specified  circumstances  to  grant  licenses  to  third  parties.  In  those
countries, we may have limited remedies if patents are infringed or if we are compelled to grant a license to a third party,
which  could  materially  diminish  the  value  of  those  patents.  This  could  limit  our  ability  to  pursue  strategic  alternatives,
including  identifying  and  consummating  transactions  with  potential  third-party  partners,  to  further  develop,  obtain
marketing approval for and/or commercialize our drug candidates, and consequently our potential revenue opportunities.
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 develop or license.

We may need to license intellectual property from third parties, and such licenses may not be available or may

not be available on commercially reasonable terms.

A  third  party  may  hold  intellectual  property,  including  patent  rights,  that  are  important  or  necessary  to  the
development and/or commercialization of our drug candidates. It may be necessary for our potential third-party partners to
use the patented or proprietary technology of third parties to further develop and/or commercialize our drug candidates. If
our potential third-party partners are not able to obtain a license from these third parties on commercially reasonable terms,
our business could be harmed, possibly materially, and even if they are able to, it may result in the reduction of revenue we
earn from such partner as a result of payment obligations such partner has to the licensor. 

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.

Our  success  depends  upon  our  ability  to  pursue  strategic  alternatives,  including  identifying  and  consummating
transactions with potential third-party partners, to develop, obtain marketing approval for and/or commercialize our drug
candidates and earn revenue from those partnerships, and for our proprietary technologies to be used without infringing the
proprietary  rights  of  third  parties.  There  is  considerable  intellectual  property  litigation  in  the  biotechnology  and
pharmaceutical  industries.  We  may  become  party  to,  or  threatened  with,  future  adversarial  proceedings  or  litigation
regarding  intellectual  property  rights  with  respect  to  our  drug  candidates  and  technologies,  including  interference  or
derivation  proceedings  before  the  USPTO.  Numerous  U.S.  and  foreign  issued  patents  and  pending  patent  applications
owned  by  third  parties  exist  in  the  fields  in  which  we  are  developing  our  drug  candidates.  Third  parties  may  assert
infringement claims against us based on existing patents or patents that may be granted in the future.

If we or our potential third-party partners are found to infringe a third party’s intellectual property rights, we or
such partners could be required to obtain a license from such third party to continue developing or commercializing our
drug candidates and technology. However, we or our potential third-party partners may not be able to obtain any required
license on commercially reasonable terms or at all. Even if we or our potential third-party partner were able to obtain a
license, it could be non-exclusive, thereby giving competitors access to the same technologies licensed to us or our partner.
Consequently,  we  or  our  potential  third-party  partner  could  be  forced,  including  by  court  order,  to  cease  developing  or
commercializing the infringing technology or drug candidate. In addition, we or our potential third-party partner could be
found liable for monetary damages, including treble damages and attorneys’ fees if we or such partner are found to have
willfully  infringed  a  patent.  A  finding  of  infringement  could  prevent  our  potential  third-party  partners  from
commercializing our drug candidates, if approved, or force such partners to cease some of their business operations. In the
event of a successful claim of infringement against us or our potential third-party partners, we or our potential third-party
partners may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, pay
royalties,  redesign  our  infringing  drug  candidate  or  obtain  one  or  more  licenses  from  third  parties,  which  may  be
impossible  or  require  substantial  time  and  monetary  expenditure.  Claims  that  we  have  misappropriated  the  confidential
information or trade secrets of third parties could have a similar negative impact on our business.

We  may  be  subject  to  claims  by  third  parties  asserting  that  we,  our  employees  or  our  licensors  have

misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.

Many  of  our  employees  and  our  licensors’  employees  were  previously  employed  at  other  biotechnology  or
pharmaceutical companies. Although we and our licensors try to ensure that our employees and our licensors’ employees
do not use the proprietary information or know-how of others in their work for us, we or our licensors may be subject to

38

Table of Contents

claims  that  these  employees,  our  licensors  or  we  have  used  or  disclosed  intellectual  property,  including  trade  secrets  or
other  proprietary  information,  of  any  such  employee’s  former  employer.  Litigation  may  be  necessary  to  defend  against
these claims. 

In  addition,  while  it  is  our  policy  to  require  our  employees  and  contractors  who  may  be  involved  in  the
development  of  intellectual  property  to  execute  agreements  assigning  such  intellectual  property  to  us,  we  may  be
unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as
our own. Our and their assignment agreements may not be self-executing or may be breached, and we may be forced to
bring  claims  against  third  parties,  or  defend  claims  they  may  bring  against  us,  to  determine  the  ownership  of  what  we
regard as our intellectual property.

If we or our licensors fail in prosecuting or defending any such claims, in addition to paying monetary damages,
we may lose valuable intellectual property rights or personnel. Even if we and our licensors are successful in prosecuting or
defending against such claims, litigation could result in substantial costs and be a distraction to management. 

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from

their normal responsibilities.

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.  We  may  not  have  sufficient  financial  or
other resources to conduct such litigation or proceedings adequately. 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. Some of
our  competitors  are  larger  than  we  are  and  have  substantially  greater  resources.  They  are,  therefore,  likely  to  be  able  to
sustain the costs of complex patent litigation longer than we could. Accordingly, despite our efforts, we may not be able to
prevent  third  parties  from  infringing  upon  or  misappropriating  our  intellectual  property.  Litigation  could  result  in
substantial  costs  and  diversion  of  management  resources,  which  could  harm  our  business.  In  addition,  the  uncertainties
associated with litigation could compromise our ability to compete in the marketplace, including compromising our ability
to  raise  the  funds  necessary  to  continue  our  clinical  trials,  continue  our  internal  research  programs,  or  pursue  strategic
alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain
marketing approval for and/or commercialize our drug candidates.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would

be harmed.

In  addition  to  seeking  and  maintaining  patents  for  our  drug  candidates,  we  also  rely  on  trade  secrets,  including
unpatented  know-how,  technology  and  other  proprietary  information,  to  maintain  our  competitive  position.  We  seek  to
protect  our  trade  secrets,  in  part,  by  entering  into  non-disclosure  and  confidentiality  agreements  with  parties  who  have
access  to  them,  such  as  our  employees,  corporate  collaborators,  outside  scientific  collaborators,  contract  manufacturers,
consultants,  advisors  and  other  third  parties.  We  also  enter  into  confidentiality  and  invention  or  patent  assignment
agreements with our employees and consultants. Despite these efforts, any of these parties may breach the agreements and
disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for
such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and
time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less
willing  or  unwilling  to  protect  trade  secrets.  If  any  of  our  trade  secrets  were  to  be  lawfully  obtained  or  independently
developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using
that  technology  or  information  to  compete  with  us.  If  any  of  our  trade  secrets  were  to  be  disclosed  to  or  independently
developed by a competitor, our competitive position would be harmed. 

The validity, scope and enforceability of any of our patents that cover any of our commercial products or any of

our drug candidates can be challenged by competitors.

The likelihood that a third party will challenge the patents covering a commercial product is increased because it

is a marketed product. The challenge may come in the form of a patent office proceeding, such as an inter partes review,

39

Table of Contents

challenging  the  validity  of  the  patents  or  a  district  court  proceeding,  such  as  a  paragraph  IV  litigation  arising  out  of  the
filing of an ANDA.

If a third party files an ANDA or 505(b)(2) application for a generic of a commercial product, and relies in whole
or in part on studies conducted by or for us, the third party will be required to certify to the FDA that either: (1) there is no
patent  information  listed  in  the  FDA’s  Orange  Book  with  respect  to  our  NDA  for  the  applicable  approved  drug;  (2)  the
patents listed in the Orange Book have expired; (3) the listed patents have not expired, but will expire on a particular date
and  approval  is  sought  after  patent  expiration;  or  (4)  the  listed  patents  are  invalid  or  will  not  be  infringed  by  the
manufacture, use or sale of the third party's generic drug. A certification that the new drug will not infringe the Orange
Book-listed patents for the applicable approved drug, or that such patents are invalid, is called a paragraph IV certification.
If the third party submits a paragraph IV certification to the FDA, a notice of the paragraph IV certification must also be
sent to us once the third party’s ANDA is accepted for filing by the FDA. We may then initiate a lawsuit to defend the
patents  identified  in  the  notice.  The  filing  of  a  patent  infringement  lawsuit  within  45  days  of  receipt  of  the  notice
automatically  prevents  the  FDA  from  approving  the  third  party’s  ANDA  until  the  earliest  of  30  months  or  the  date  on
which the patent expires, the lawsuit is settled, or the court reaches a decision in the infringement lawsuit in favor of the
third party. If we do not file a patent infringement lawsuit within the required 45-day period, the third party’s ANDA will
not  be  subject  to  the  30-month  stay  of  FDA  approval.  Litigation  or  other  proceedings  to  enforce  or  defend  intellectual
property  rights  are  often  very  complex  in  nature,  may  be  very  expensive  and  time-consuming,  may  divert  our
management's attention from our core business, and may result in unfavorable results that could limit our ability to prevent
third parties from competing with our commercial products. 

If any of our drug candidates advance through development or are approved by the FDA, one or more third parties
may  challenge  the  current  patents,  or  patents  that  may  issue  in  the  future,  within  our  portfolio  covering  these  drug
candidates.  Any  such  challenge  could  result  in  the  invalidation  of,  or  render  unenforceable,  some  or  all  of  the  relevant
patent  claims  or  a  finding  of  non-infringement,  which  would  harm  our  ability  to  pursue  strategic  alternatives,  including
identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for
and/or commercialize our drug candidates, and earn revenue from such arrangements. In addition, any such challenge on
any divested product could harm our ability to earn revenue from the arrangements for such product. 

If we do not obtain protection under the Hatch-Waxman Act by extending the patent term and obtaining data

exclusivity for our drug candidates, our business may be materially harmed.

Our success will largely depend on our ability to obtain and maintain patent and other intellectual property in the
United  States  and  other  countries  with  respect  to  our  proprietary  technology,  drug  candidates  and  our  target
indications.  Our issued U.S. patents covering ATI-450, our lead inhibitor of the MK2 signaling pathway, expire in 2034,
and other issued patents covering different MK2 signaling pathway inhibitors expire in 2031 and 2032. We currently do not
have any patents issued directed to our lead “soft” JAK inhibitor, ATI-1777, but any claims that may issue would expire in
2038. Our issued patent covering other novel “soft” JAK inhibitors expires 2038.  We currently do not have any patents
issued  directed  to  our  lead  ITK  inhibitor,  ATI-2138,  but  any  claims  that  may  issue  would  expire  in  2039.    Our  issued
patents covering other novel inhibitors of ITK expire between 2035 and 2038. Given the amount of time required for the
development, testing and regulatory review of new drug candidates, patents protecting our drug candidates might expire
before or shortly after such candidates begin to be commercialized. We expect to seek extensions of patent terms in the
United States and, if available, in other countries where we are prosecuting patents.

Depending  upon  the  timing,  duration  and  specifics  of  FDA  marketing  approval  of  our  drug  candidates,  one  or
more of our U.S. patents may be eligible for limited patent term extension under The Drug Price Competition and Patent
Term Restoration Act of 1984, or the Hatch-Waxman Act, for a drug candidate. The Hatch-Waxman Act permits a patent
extension term of up to five years beyond the normal expiration of the patent as compensation for patent term lost during
development  and  the  FDA  regulatory  review  process,  which  is  limited  to  the  approved  indication  (or  any  additional
indications  approved  during  the  period  of  extension).  However,  the  total  patent  term  including  the  period  of  extension
cannot  exceed  14  years  from  the  product’s  approval  date.    Furthermore,  this  extension  is  limited  to  only  one  patent  per
regulatory review period that covers the approved product. However, the applicable authorities, including the FDA and the
USPTO in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment
of  whether  such  extensions  are  available,  and  may  refuse  to  grant  extensions  to  our  patents,  or  may  grant  more  limited
extensions than we request. We may not be granted an extension because of, for example, failing to apply within

40

Table of Contents

applicable  deadlines,  failing  to  apply  prior  to  expiration  of  relevant  patents  or  otherwise  failing  to  satisfy  applicable
requirements.  Moreover,  the  applicable  time  period  or  the  scope  of  patent  protection  afforded  could  be  less  than  we
request.

If  we  are  unable  to  extend  the  expiration  date  of  our  existing  patents  or  obtain  new  patents  with  longer  expiry
dates, our competitors may be able to take advantage of our investment in development and clinical trials by referencing
our clinical and preclinical data to obtain approval of competing products following our patent expiration and launch their
product earlier than might otherwise be the case.

Any  trademarks  we  have  obtained  or  may  obtain  may  be  infringed  or  successfully  challenged,  resulting  in

harm to our business.

We expect to rely on trademarks as one means to distinguish our products, services or technologies from those of
our  competitors.  Once  we  select  new  trademarks  and  apply  to  register  them,  our  trademark  applications  may  not  be
approved. Third parties may oppose or attempt to cancel our trademark applications or trademarks, or otherwise challenge
our use of the trademarks. In such an event, we may need to negotiate a settlement agreement with such third party over the
use of our trademarks, which we may not be able to do on commercially reasonable terms, if at all. In the event that our
trademarks  are  successfully  challenged,  our  products,  services  or  technologies  may  need  to  be  rebranded,  which  could
result in loss of brand recognition and could require us to devote resources to advertising and marketing new brands. Our
competitors may infringe our trademarks and we may not have adequate resources to enforce our trademarks.

Outside  of  the  United  States  we  cannot  be  certain  that  any  country’s  patent  or  trademark  office  will  not
implement  new  rules  that  could  seriously  affect  how  we  draft,  file,  prosecute  and  maintain  patents,  trademarks  and
patent and trademark applications.

We cannot be certain that the patent or trademark offices of countries outside the United States will not implement
new rules that increase costs for drafting, filing, prosecuting and maintaining patents, trademarks and patent and trademark
applications or that any such new rules will not restrict our ability to file for patent protection. For example, we may elect
not to seek patent protection in some jurisdictions or for some drug candidates in order to save costs. We may be forced to
abandon or return the rights to specific patents due to a lack of financial resources.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

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. The following examples are illustrative:

● we, our licensors or any potential third-party partners might not have been the first to make the inventions

covered by the issued patents or pending patent applications that we own;

● we, our licensors or any potential third-party partners might not have been the first to file patent applications

covering certain of our inventions;

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

without infringing our intellectual property rights;

● it is possible that our pending patent applications will not lead to issued patents;
● issued patents that we own or exclusively license may not provide us with any competitive advantages, or

may be held invalid or unenforceable as a result of legal challenges;

● our competitors might conduct research and development activities in the United States and other countries
that provide a safe harbor from patent infringement claims for certain research and development activities, as
well  as  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 major commercial markets; and

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

Risks Related to Regulatory Approval of Our Drug Candidates and Other Legal Compliance Matters

If  our  potential  third-party  partners  are  not  able  to  obtain,  or  if  there  are  delays  in  obtaining,  required
regulatory approvals, our drug candidates will not be able to be commercialized, and our ability to earn revenue from
arrangements with such third-party partners will be materially impaired.

Our drug candidates and the activities associated with their development and commercialization, including their
design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale and
distribution, are subject to comprehensive regulation by the FDA, other regulatory agencies in the United States and similar
regulatory authorities outside the United States. Failure to obtain marketing approval for a drug candidate will prevent our
potential  third-party  partners  from  commercializing  the  drug  candidate.  We  have  only  limited  experience  in  filing  and
supporting the applications necessary to gain marketing approvals. Securing marketing approval requires the submission of
extensive preclinical and clinical data and supporting information to regulatory authorities for each therapeutic indication
to  establish  the  drug  candidate’s  safety  and  efficacy.  Securing  marketing  approval  also  requires  the  submission  of
information  about  the  drug  manufacturing  process  to,  and  inspection  of  manufacturing  facilities  by,  the  regulatory
authorities. Our drug candidates may not be effective, may be only moderately effective or may prove to have undesirable
or  unintended  side  effects,  toxicities  or  other  characteristics  that  may  preclude  our  potential  third-party  partners  from
obtaining marketing approval or prevent or limit commercial use. If any of our drug candidates receive marketing approval,
the accompanying label may limit the approved use of our product in this way, which could limit sales of the product. 

The process of obtaining marketing approvals, both in the United States and abroad, is expensive and may take
many years if additional clinical trials are required, if approval is obtained at all, and can vary substantially based upon a
variety  of  factors,  including  the  type,  complexity  and  novelty  of  the  drug  candidates  involved.  Changes  in  marketing
approval  policies  during  the  development  period,  changes  in  or  the  enactment  of  additional  statutes  or  regulations,  or
changes  in  regulatory  review  for  each  submitted  drug  application,  may  cause  delays  in  the  approval  or  rejection  of  an
application.  Regulatory  authorities  have  substantial  discretion  in  the  approval  process  and  may  refuse  to  accept  any
application  or  may  decide  that  our  data  is  insufficient  for  approval  and  require  additional  preclinical,  clinical  or  other
studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or
prevent  marketing  approval  of  a  drug  candidate.  Any  marketing  approval  our  potential  third-party  partners  ultimately
obtain  may  be  limited  or  subject  to  restrictions  or  post-approval  commitments  that  render  the  approved  drug  not
commercially viable.

If our potential third-party partners experience delays in obtaining approval or if they fail to obtain approval of our
drug candidates, the commercial prospects for our drug candidates may be harmed and our ability to earn revenue from
arrangements with such third-party partners will be materially impaired.

Failure  to  obtain  marketing  approval  in  international  jurisdictions  would  prevent  our  drug  candidates  from

being marketed abroad.

In order to market and sell our drugs in the European Union and any other jurisdictions outside the United States,
our  potential  third-party  partners  must  obtain  separate  marketing  approvals  and  comply  with  numerous  and  varying
regulatory  requirements.  The  approval  procedure  varies  among  countries  and  can  involve  additional  testing.  The  time
required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval
process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in
many countries outside the United States, it is required that the drug be approved for reimbursement before the drug can be
approved for sale in that country. Our potential third-party partners may not obtain approvals from regulatory authorities
outside  the  United  States  on  a  timely  basis,  if  at  all.  Approval  by  the  FDA  does  not  ensure  approval  by  regulatory
authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United States does not
ensure  approval  by  regulatory  authorities  in  other  countries  or  jurisdictions  or  by  the  FDA.  However,  failure  to  obtain
approval  in  one  jurisdiction  may  impact  our  potential  third-party  partners’  ability  to  obtain  approval  elsewhere.  Our
potential third-party partners may not be able to file for marketing approvals and may not receive necessary approvals to
commercialize our drug candidates in any market.

A  variety  of  risks  associated  with  marketing  our  drug  candidates  by  our  potential  third-party  partners

internationally could harm our business.

If our drug candidates, if approved, are marketed internationally by our potential third-party partners, our potential

third-party partners would be subject to additional risks related to operating in foreign countries, including:

● differing regulatory requirements in foreign countries;
● the potential for so-called parallel importing, which is what happens when a local seller, faced with high or
higher local prices, opts to import goods from a foreign market (with low or lower prices) rather than buying
them locally;

● unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements;
● economic weakness, including inflation, or political instability in particular foreign economies and markets;
● foreign reimbursement, pricing and insurance regimes;
● compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;
● foreign taxes, including withholding of payroll taxes;
● foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and

other obligations incident to doing business in another country;

● difficulties staffing and managing foreign operations;
● workforce uncertainty in countries where labor unrest is more common than in the United States;
● potential  liability  under  the  U.S.  Foreign  Corrupt  Practices  Act  of  1977,  as  amended,  or  the  FCPA,  or

comparable foreign regulations;

● challenges enforcing contractual and intellectual property rights, especially in those foreign countries that do

not respect and protect intellectual property rights to the same extent as the United States;

● production shortages resulting from any events affecting raw material supply or manufacturing capabilities

abroad;

● logistical challenges resulting from distributing our drug candidates to foreign countries; and
● business interruptions resulting from geo-political actions, including war and terrorism.

These and other risks associated with international operations may compromise our ability to earn revenue from

arrangements with potential third-party partners for our drug candidates.

Any drug candidate for which our potential third-party partners obtain marketing approval could be subject to
post-marketing  restrictions  or  recall  or  withdrawal  from  the  market,  and  our  potential  third-party  partners  may  be
subject to penalties if they fail to comply with regulatory requirements or if they experience unanticipated problems with
our drug candidates, when and if any of them are approved.

Any  drug  candidate  for  which  our  potential  third-party  partners  obtain  marketing  approval,  along  with  the
manufacturing  processes,  post-approval  clinical  data,  labeling,  advertising  and  promotional  activities  for  such  drug
candidate,  will  be  subject  to  continual  requirements  of  and  review  by  the  FDA  and  other  regulatory  authorities.  These
requirements  include  submissions  of  safety  and  other  post-marketing  information  and  reports,  registration  and  listing
requirements,  cGMP  requirements  relating  to  manufacturing,  quality  control,  quality  assurance  and  corresponding
maintenance  of  records  and  documents,  requirements  regarding  the  distribution  of  samples  to  physicians  and
recordkeeping. Even if marketing approval of a drug candidate is granted, the approval may be subject to limitations on the
indicated uses for which the drug candidate may be marketed or to the conditions of approval, including the requirement to
implement  a  risk  evaluation  and  mitigation  strategy.  If  any  of  our  drug  candidates  receives  marketing  approval,  the
accompanying label may limit the approved use of our drug, which could limit sales of the drug by our potential third-party
partners.

The  FDA  may  also  impose  requirements  for  costly  post-marketing  studies  or  clinical  trials  and  surveillance  to
monitor the safety or efficacy of the drug. The FDA closely regulates the post-approval marketing and promotion of drugs
to  ensure  drugs  are  marketed  only  for  the  approved  indications  and  in  accordance  with  the  provisions  of  the  approved
labeling.  The  FDA  imposes  stringent  restrictions  on  manufacturers’  communications  regarding  off-label  use  and  if  our
potential third-party partners do not market our drugs for their approved indications, they may be subject to enforcement
action for off-label marketing. Physicians, on the other hand, may prescribe products for off-label uses. Although the FDA
and other regulatory agencies do not regulate a physician’s choice of drug treatment made in the physician’s independent
medical judgment, they do restrict promotional communications from companies or their sales force with respect to off-

43

Table of Contents

label uses of products for which marketing clearance has not been issued. However, companies may share truthful and not
misleading  information  that  is  otherwise  consistent  with  the  product’s  FDA  approved  labeling.  Violations  of  the  FDCA
relating to the promotion of prescription drugs may lead to investigations alleging violations of federal and state health care
fraud and abuse laws, as well as state consumer protection laws.

In  addition,  later  discovery  of  previously  unknown  adverse  events  or  other  problems  with  our  drugs,
manufacturers  or  manufacturing  processes,  or  failure  to  comply  with  regulatory  requirements,  may  have  negative
consequences, including:

● restrictions on such drugs, manufacturers or manufacturing processes;
● restrictions on the labeling or marketing of a drug;
● restrictions on drug distribution or use;
● requirements to conduct post-marketing studies or clinical trials;
● warning letters;
● recall or withdrawal of the drugs from the market;
● refusal to approve pending applications or supplements to approved applications;
● clinical holds;
● fines, restitution or disgorgement of profits or revenue;
● suspension or withdrawal of marketing approvals;
● refusal to permit the import or export of our drugs;
● drug seizure; or
● injunctions or the imposition of civil or criminal penalties.

Non-compliance with the European Union’s requirements regarding safety monitoring or pharmacovigilance, and
with requirements related to the development of drugs for the pediatric population, can also result in significant financial
penalties.  Similarly,  failure  to  comply  with  the  European  Union’s  requirements  regarding  the  protection  of  personal
information can also lead to significant penalties and sanctions. These and other risks associated with the failure by our
potential  third-party  partners  to  comply  with  regulatory  requirements  may  compromise  our  ability  to  earn  revenue  from
arrangements with such third-party partners for our drug candidates.

Our  potential  third-party  partners’  relationships  with  third-party  payors,  health  care  professionals  and
customers in the United States and elsewhere may be subject, directly or indirectly, to applicable anti-kickback, fraud
and abuse, false claims, physician payment transparency, health information privacy and security and other health care
laws and regulations, and any failure to comply with such laws and regulations could have a material adverse effect on
our ability to earn revenue from arrangements with such third-party partners for our drug candidates.

Health care providers, physicians and third-party payors in the United States and elsewhere will play a primary
role in the recommendation and prescription of any of our drug candidates for which marketing approval is obtained. Our
potential third-party partners’ arrangements with third-party payors, health care professionals and customers may expose
them to broadly applicable fraud and abuse and other health care laws and regulations, including, without limitation, the
federal  Anti-Kickback  Statute  and  the  federal  civil  False  Claims  Act,  that  may  constrain  the  business  or  financial
arrangements  and  relationships  through  which  they  sell,  market  and  distribute  any  drug  candidates  for  which  marketing
approval is obtained. In addition, we and our potential third-party partners may be subject to transparency laws and patient
privacy regulation by the federal government and by the U.S. states and foreign jurisdictions in which we or they conduct
business.  The  applicable  federal,  state  and  foreign  health  care  laws  and  regulations  that  may  affect  our  or  our  potential
third-party partners’ ability to operate include the following:

● the federal Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly
and  willfully  soliciting,  offering,  receiving  or  providing  remuneration,  directly  or  indirectly,  in  cash  or  in
kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or
recommendation of, any good or service, for which payment may be made under federal and state health care
programs  such  as  Medicare  and  Medicaid.  Further,  several  courts  have  interpreted  the  statute’s  intent
requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals
of  federal  health  care  covered  business,  the  Anti-Kickback  Statute  has  been  violated.   The  intent  standard
was further amended by the Affordable Care Act, to a stricter standard such that a person or entity no longer
needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a

44

Table of Contents

violation.    Moreover,  the  government  may  assert  that  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 False
Claims Act;

● federal civil and criminal false claims laws, including, without limitation, the federal civil False Claims Act
(that can be enforced through civil whistleblower or qui tam actions), and the civil monetary penalties law,
which  impose  criminal  and  civil  penalties,  against  individuals  or  entities  for  knowingly  presenting,  or
causing to be presented, to the federal government, including the Medicare and Medicaid programs, claims
for  payment  that  are  false  or  fraudulent  or  making  a  false  statement  to  avoid,  decrease  or  conceal  an
obligation to pay money to the federal government;

● federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and
civil  liability  for,  among  other  things,  executing  a  scheme  to  defraud  any  health  care  benefit  program  or
making false statements relating to health care matters. Similar to the federal Anti-Kickback Statute, a person
or  entity  does  not  need  to  have  actual  knowledge  of  the  statute  or  specific  intent  to  violate  it  to  have
committed a violation;

● HIPAA, as amended by HITECH, and their respective implementing regulations, which impose obligations
on  covered  health  care  providers,  health  plans,  and  health  care  clearinghouses,  as  well  as  their  business
associates  that  create,  receive,  maintain  or  transmit  individually  identifiable  health  information  for  or  on
behalf of a covered entity and their subcontractors that use, disclose, access, or otherwise process protected
health  information,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of  individually
identifiable health information;

● the  federal  Open  Payments  program,  created  under  Section  6002  of  the  Affordable  Care  Act  (commonly
known as the Physician Payments Sunshine Act) and its implementing regulations, which requires specified
manufacturers  of  drugs,  devices,  biologics  or  medical  supplies  for  which  payment  is  available  under
Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to report annually
to CMS information related to payments or other “transfers of value” made to physicians, which is defined to
include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors  and  teaching  hospitals,  as  well  as
applicable manufacturers to report annually to CMS ownership and investment interests held by physicians
and their immediate family members, and, beginning in 2022, will require applicable manufacturers to report
information  related  to  payments  and  other  transfers  of  value  provided  in  the  previous  year  to  physician
assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified 
registered  nurse  anesthetists,
anesthesiologist assistants and certified nurse midwives. All such reported information is publicly available;
and

● analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which
may apply to sales or marketing arrangements and claims involving health care items or services reimbursed
by  non-governmental  third-party  payors,  including  private  insurers;  state  and  foreign  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 health care providers; state, local and foreign laws that require drug manufacturers to
report  information  related  to  payments  and  other  transfers  of  value  to  physicians  and  other  health  care
providers or marketing expenditures; state laws that require drug manufacturers to report pricing information
regarding certain drugs; and/or that require registration of certain employees engaged in marketing activities
in the location; and state and foreign 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.

Efforts  to  ensure  that  our  or  our  potential  third-party  partners’  business  arrangements  with  third  parties  will
comply  with  applicable  health  care  laws  and  regulations  may  involve  substantial  costs.  It  is  possible  that  governmental
authorities  will  conclude  that  our  or  our  potential  third-party  partners’  business  practices,  including  relationships  with
physicians and other health care providers, some of whom may recommend, purchase and/or prescribe our drug candidates,
if approved, may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or
other health care laws and regulations. By way of example, some of our consulting arrangements with physicians may not
meet all of the criteria of the personal services safe harbor under the federal Anti-Kickback Statute. Accordingly, they may
not  qualify  for  safe  harbor  protection  from  government  prosecution.  A  business  arrangement  that  does  not  substantially
comply  with  a  safe  harbor,  however,  is  not  necessarily  illegal  under  the  Anti-Kickback  Statute,  but  may  be  subject  to
additional scrutiny by the government.

45

Table of Contents

If our or our potential third-party partners’ operations are found to be in violation of any of these laws or any other
governmental  regulations  that  may  apply  to  us  or  them,  we  or  our  potential  third-party  partners  may  be  subject  to
significant  civil,  criminal  and  administrative  penalties,  including,  without  limitation,  damages,  fines,  disgorgement,
imprisonment,  exclusion  from  participation  in  government  health  care  programs,  such  as  Medicare  and  Medicaid,
additional reporting requirements and oversight if we or they become subject to a corporate integrity agreement or similar
agreement  to  resolve  allegations  of  non-compliance  with  these  laws  and  the  curtailment  or  restructuring  of  our  or  their
operations, which could have a material adverse effect on our ability to earn revenue from arrangements with such third-
party  partners  for  our  drug  candidates.  If  any  physician  or  other  health  care  provider  or  entity  with  whom  we  or  our
potential third-party partners expect to do business is found not to be in compliance with applicable laws, it may be subject
to significant criminal, civil or administrative sanctions, including exclusions from participation in government health care
programs, which could also materially affect our ability to earn revenue from arrangements with such third-party partners
for our drug candidates.

Recently  enacted  and  future  legislation  may  increase  the  difficulty  and  cost  for  our  potential  third-party
partners to obtain marketing approval of our drug candidates and commercialize our drug candidates, if approved, and
affect the prices our potential third-party partners may obtain.

In  the  United  States,  and  some  foreign  jurisdictions,  there  have  been  a  number  of  legislative  and  regulatory
changes and proposed changes regarding the health care system that could prevent or delay marketing approval of our drug
candidates, restrict or regulate post-approval activities and affect our potential third-party partners’ ability to profitably sell
any of our drug candidates for which our potential third-party partners obtain marketing approval, and consequently affect
our ability to earn revenue from arrangements with such third-party partners for our drug candidates.

Among  policy  makers  and  payors  in  the  United  States  and  elsewhere,  there  is  significant  interest  in  promoting
changes in health care systems with the stated goals of containing health care costs, improving quality and/or expanding
access.  In  the  United  States,  the  pharmaceutical  industry  has  been  a  particular  focus  of  these  efforts  and  has  been
significantly affected by major legislative initiatives.  The Affordable Care Act, which was signed into law in 2010, is a
sweeping  law  intended  to  broaden  access  to  health  insurance,  reduce  or  constrain  the  growth  of  health  care  spending,
enhance  remedies  against  fraud  and  abuse,  add  new  transparency  requirements  for  the  health  care  and  health  insurance
industries, impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the Affordable Care Act of importance to commercial products are the following:

● an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs
and biologic agents, apportioned among these entities according to their market share in certain government
health care programs;

● an  increase  in  the  statutory  minimum  rebates  a  manufacturer  must  pay  under  the  Medicaid  Drug  Rebate
Program to 23.1% and 13.0% of the average manufacturer price for branded and generic drugs, respectively;
● expansion  of  health  care  fraud  and  abuse  laws,  including  the  False  Claims  Act  and  the  Anti-Kickback
Statute, which include, among other things, new government investigative powers and enhanced penalties for
non-compliance;

● 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;

● extension  of  manufacturers’  Medicaid  rebate  liability  to  covered  drugs  dispensed  to  individuals  who  are

enrolled in Medicaid managed care organizations;

● expansion  of  eligibility  criteria  for  Medicaid  programs  by,  among  other  things,  allowing  states  to  offer
Medicaid coverage to additional individuals, thereby potentially increasing manufacturers’ Medicaid rebate
liability;

● expansion  of  the  entities  eligible  for  discounts  under  the  Public  Health  Service  pharmaceutical  pricing

program;

● the new requirements under the federal Open Payments program and its implementing regulations;
● a new requirement to annually report drug samples that manufacturers and distributors provide to physicians;

and

46

● a  new  Patient-Centered  Outcomes  Research  Institute  to  oversee,  identify  priorities  in,  and  conduct

comparative clinical effectiveness research, along with funding for such research.

There remain judicial and Congressional challenges to certain aspects of the Affordable Care Act. While Congress
has  not  passed  comprehensive  repeal  legislation,  several  bills  affecting  the  implementation  of  certain  taxes  under  the
Affordable  Care  Act  have  been  signed  into  law.  The  Tax  Cuts  and  Jobs  Act  of  2017,  or  the  2017  Tax  Act,  includes  a
provision that repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the Affordable
Care Act 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”.  Additionally, the 2020 federal spending package permanently eliminated, effective
January 1, 2020, the Affordable Care Act-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and
medical device tax and, effective January 1, 2021, also eliminated the health insurer tax.  Further, the Bipartisan Budget
Act of 2018, or the BBA, among other things, amended the Affordable Care Act, effective January 1, 2019, to close the
coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”.  On December 14, 2018, a Texas
U.S.  District  Court  Judge  ruled  that  the  Affordable  Care  Act  is  unconstitutional  in  its  entirety  because  the  “individual
mandate” was repealed by Congress as part of the 2017 Tax Act. Additionally, on December 18, 2019, the U.S. Court of
Appeals  for  the  Fifth  Circuit  upheld  the  District  Court  ruling  that  the  individual  mandate  was  unconstitutional  and
remanded the case back to the District Court to determine whether the remaining provisions of the Affordable Care Act are
invalid as well.  The U.S. Supreme Court is currently reviewing the case, although it is unknown when a decision will be
made. Further, although the U.S. Supreme Court has not yet ruled on the constitutionality of the Affordable Care Act, on
January 28, 2021, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021
through May 15, 2021 for purposes of obtaining health insurance coverage through the Affordable Care Act marketplace.
The executive order also instructs certain governmental agencies to review and reconsider their existing policies and rules
that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs
that  include  work  requirements,  and  policies  that  create  unnecessary  barriers  to  obtaining  access  to  health  insurance
coverage through Medicaid or the Affordable Care Act. It is unclear how the Supreme Court ruling, other such litigation,
and the health care reform measures of the Biden administration will impact the Affordable Care Act and our business.

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted.
These  changes  included  aggregate  reductions  to  Medicare  payments  to  providers  of  2%  per  fiscal  year  that  became
effective on April 1, 2013 and, due to subsequent legislative amendments to the statute, including the BBA, will stay in
effect  through  2030  with  the  exception  of  a  temporary  suspension  from  May  1,  2020  through  March  31,  2021  unless
additional  Congressional  action  is  taken.    The  American  Taxpayer  Relief  Act  of  2012,  which  was  signed  into  law  in
January  2013,  among  other  things,  further  reduced  Medicare  payments  to  several  providers,  and  increased  the  statute  of
limitations period for the government to recover overpayments to providers from three to five years. Any similar new laws
may result in additional reductions in Medicare and other health care funding, which could have a material adverse effect
on our ability to earn revenue from arrangements with our potential third-party partners for our drug candidates.

We expect that the Affordable Care Act, as well as other health care reform measures that may be adopted in the
future, may result in more rigorous coverage criteria and in additional downward pressure on the price that our potential
third-party  partners  receive  for  any  approved  drug  candidate.  Any  reduction  in  reimbursement  from  Medicare  or  other
government  programs  may  result  in  a  similar  reduction  in  payments  from  private  payors.  The  implementation  of  cost
containment  measures  or  other  health  care  reforms  may  prevent  our  potential  third-party  partners  from  being  able  to
generate  revenue,  attain  profitability,  or  commercialize  our  drug  candidates,  if  approved,  which  in  turn  may  impact  our
ability to earn revenue from arrangements with such third-party partners for our drug candidates. Further, it is also possible
that additional governmental action is taken in response to the COVID-19 pandemic.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and
promotional  activities  for  drugs.    In  addition,  there  has  been  heightened  governmental  scrutiny  in  the  United  States  of
pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in
several  recent  Congressional  inquiries  and  proposed  and  enacted  federal  and  state  legislation  designed  to,  among  other
things,  bring  more  transparency  to  drug  pricing,  review  the  relationship  between  pricing  and  manufacturer  patient
programs,  and  reform  government  program  reimbursement  methodologies  for  drugs.  At  the  federal  level,  the  Trump
administration  used  several  means  to  propose  or  implement  drug  pricing  reform,  including  through  federal  budget
proposals, executive orders and policy initiatives. For example, on July 24, 2020 and September 13, 2020, President Trump
announced  several  executive  orders  related  to  prescription  drug  pricing  that  seek  to  implement  several  of  the
administration’s proposals. As a result, the FDA released a final rule on September 24, 2020, effective November 30,

47

Table of Contents

2020, providing guidance for states to build and submit importation plans for drugs from Canada. Further, on November
20,  2020,  HHS  finalized  a  regulation  removing  safe  harbor  protection  for  price  reductions  from  pharmaceutical
manufacturers  to  plan  sponsors  under  Part  D,  either  directly  or  through  pharmacy  benefit  managers,  unless  the  price
reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1,
2022  to  January  1,  2023  in  response  to  ongoing  litigation.  The  rule  also  creates  a  new  safe  harbor  for  price  reductions
reflected  at  the  point-of-sale,  as  well  as  a  new  safe  harbor  for  certain  fixed  fee  arrangements  between  pharmacy  benefit
managers  and  manufacturers,  the  implementation  of  which  have  also  been  delayed  pending  review  by  the  Biden
administration  until  March  22,  2021.  On  November  20,  2020,  CMS  issued  an  interim  final  rule  implementing  President
Trump’s  Most  Favored  Nation  executive  order,  which  would  tie  Medicare  Part  B  payments  for  certain  physician-
administered  drugs  to  the  lowest  price  paid  in  other  economically  advanced  countries,  effective  January  1,  2021.  On
December  28,  2020,  the  U.S.  District  Court  in  Northern  California  issued  a  nationwide  preliminary  injunction  against
implementation of the interim final rule. It is unclear whether the Biden administration will work to reverse these measures
or pursue similar policy initiatives. At the state level, legislatures have become increasingly active in passing legislation
and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient
reimbursement  constraints,  discounts,  restrictions  on  certain  drug  access  and  marketing  cost  disclosure  and  transparency
measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.  We cannot be
sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations
will be changed, or what the impact of such changes on obtaining marketing approvals for our drug candidates, if any, may
be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent
marketing approval, as well as subject our potential third-party partners to more stringent drug labeling and post-marketing
testing  and  other  requirements.  These  risks  may  compromise  our  ability  to  earn  revenue  from  arrangements  with  such
third-party partners for our drug candidates.

Governments  outside  the  United  States  tend  to  impose  strict  price  controls,  which  may  adversely  affect  our

revenue.

In some countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is
subject  to  governmental  control.  In  these  countries,  pricing  negotiations  with  governmental  authorities  can  take
considerable  time  after  the  receipt  of  marketing  approval  for  a  drug.  To  obtain  coverage  and  reimbursement  or  pricing
approval in some countries, our potential third-party partners may be required to conduct a clinical trial that compares the
cost-effectiveness  of  our  drug  candidate  to  other  available  procedures.  If  reimbursement  of  our  drug  candidates  is
unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our potential third-party partners may
not able to generate revenue, which in turn may adversely affect our ability to earn revenue from arrangements with such
third-party partners for our drug candidates. 

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 harm 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 for failure to comply with such laws and regulations. 

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, hazardous or radioactive materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and
safety laws and regulations. These current or future laws and regulations may impair our development or manufacturing
efforts.  Our  failure  to  comply  with  these  laws  and  regulations  also  may  result  in  substantial  fines,  penalties  or  other
sanctions.  

48

Table of Contents

We  are  subject  to  governmental  economic  sanctions  and  export  and  import  controls  that  could  impair  our
potential  third-party  partners’  ability  to  compete  in  international  markets  or  subject  us  or  our  potential  third-party
partners to liability if we or they are not in compliance with applicable laws.

As  a  U.S.  company,  we  are  subject  to  U.S.  import  and  export  controls  and  economic  sanctions  laws  and
regulations,  and  we  are  required  to  import  and  export  our  drug  candidates,  technology  and  services  in  compliance  with
those  laws  and  regulations,  including  the  U.S.  Export  Administration  Regulations,  the  International  Traffic  in  Arms
Regulations,  and  economic  embargo  and  trade  sanction  programs  administered  by  the  Treasury  Department’s  Office  of
Foreign Assets Control.  

U.S.  economic  sanctions  and  export  control  laws  and  regulations  prohibit  the  shipment  of  certain  products  and
services to countries, governments and persons targeted by U.S. sanctions. While we are currently taking precautions to
prevent doing any business, directly or indirectly, with countries, governments and persons targeted by U.S. sanctions and
to  ensure  that  our  drug  candidates  are  not  exported  or  used  by  countries,  governments  and  persons  targeted  by  U.S.
sanctions, such measures may be circumvented.  

Furthermore,  if  we  or  our  potential  third-party  partners  export  our  drug  candidates,  the  exports  may  require
authorizations,  including  a  license,  a  license  exception  or  other  appropriate  government  authorization.  Complying  with
export control and sanctions regulations may be time-consuming and may result in the delay or loss of sales opportunities.
Failure  to  comply  with  export  control  and  sanctions  regulations  may  expose  us  or  our  potential  third-party  partners  to
government investigations and penalties.  

If we are found to be in violation of U.S. sanctions or import or export control laws, it could result in civil and
criminal, monetary and non-monetary penalties, including possible incarceration for those individuals responsible for the
violations, the loss of export or import privileges and reputational harm.

We and our potential third-party partners are subject to anti-corruption and anti-money laundering laws with
respect to our and their operations and non-compliance with such laws can subject us to criminal and/or civil liability
and harm our business.

We and our potential third-party partners are subject to the FCPA, the U.S. domestic bribery statute contained in
18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act and possibly other anti-bribery and anti-money laundering
laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and
their  employees  and  third-party  intermediaries  from  authorizing,  offering  or  providing,  directly  or  indirectly,  improper
payments or benefits to recipients in the public or private sector. We or our potential third-party partners may engage third-
party intermediaries in connection with the development or commercialization of our drug candidates, if approved, and to
obtain necessary permits, licenses and other regulatory approvals. We, our potential third-party partners or the third-party
intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned
or affiliated entities. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our
employees, representatives, contractors, partners and agents, even if we do not explicitly authorize such activities. 

Noncompliance  with  anti-corruption  and  anti-money  laundering  laws  could  subject  us  to  whistleblower
complaints,  investigations,  sanctions,  settlements,  prosecution,  other  enforcement  actions,  disgorgement  of  profits,
significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting
with  certain  persons,  the  loss  of  export  privileges,  reputational  harm,  adverse  media  coverage  and  other  collateral
consequences. Responding to any action will likely result in a materially significant diversion of management’s attention
and resources and significant defense costs and other professional fees.

Risks Related to Employee Matters and Managing Our Growth

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified

personnel.

We  are  highly  dependent  on  the  management,  development,  clinical,  financial,  legal  and  business  development
expertise of Dr. Neal Walker, our Chief Executive Officer, Dr. David Gordon, our Chief Medical Officer, Frank Ruffo, our
Chief Financial Officer, and Kamil Ali-Jackson, our Chief Legal Officer, as well as the other members of our scientific and
clinical teams. Although we have entered into employment agreements with certain of our executive officers, each of

49

Table of Contents

them may currently terminate their employment with us or resign at any time.  We do not maintain “key person” insurance
for any of our key executives other than for Dr. Walker. 

Recruiting  and  retaining  qualified  scientific,  manufacturing  and  clinical  personnel  will  also  be  critical  to  our
success. The loss of the services of our executive officers or other key employees could impede the achievement of our
development  objectives  and  seriously  harm  our  ability  to  successfully  implement  our  business  strategy.  Furthermore,
replacing executive officers and key employees may be difficult and may take an extended period of time because of the
limited number of individuals in our industry with the breadth of skills and experience required to successfully develop and
partner drug candidates. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or
motivate  these  key  personnel  on  acceptable  terms  given  the  competition  among  numerous  pharmaceutical  and
biotechnology  companies  for  similar  personnel.  We  also  experience  competition  for  the  hiring  of  scientific  and  clinical
personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific
and  clinical  advisors,  to  assist  us  in  formulating  our  development  strategy.  Our  consultants  and  advisors  may  have
commitments under employment, consulting or advisory contracts with other entities that may limit their availability to us.
If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be
limited. 

Our employees, independent contractors, consultants, third-party partners, principal investigators, CROs and
vendors  may  engage  in  misconduct  or  other  improper  activities,  including  non-compliance  with  regulatory  standards
and requirements.

We are exposed to the risk that our employees, independent contractors, consultants, third-party partners, principal
investigators, CROs and vendors may engage in fraudulent conduct or other illegal activity. Misconduct by these parties
could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violates FDA
regulations,  including  those  laws  requiring  the  reporting  of  true,  complete  and  accurate  information  to  the  FDA,
manufacturing standards, federal and state health care laws and regulations, and laws that require the true, complete and
accurate  reporting  of  financial  information  or  data.  In  particular,  sales,  marketing  and  business  arrangements  by  our
potential third-party partners in the health care industry are subject to extensive laws and regulations intended to prevent
fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range
of  pricing,  discounting,  marketing  and  promotion,  sales  commission,  customer  incentive  programs  and  other  business
arrangements.  Misconduct  by  these  parties  could  also  involve  the  improper  use  of  individually  identifiable  information,
including,  without  limitation,  information  obtained  in  the  course  of  clinical  trials,  which  could  result  in  regulatory
sanctions and serious harm to our reputation. We have adopted a code of business conduct and ethics, but it is not always
possible  to  identify  and  deter  misconduct,  and  the  precautions  we  take  to  detect  and  prevent  this  activity  may  not  be
effective  in  controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  us  from  governmental  investigations  or
other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are
instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a
significant  impact  on  our  business,  including  the  imposition  of  significant  civil,  criminal  and  administrative  penalties,
including,  without  limitation,  damages,  fines,  disgorgement,  imprisonment,  exclusion  from  participation  in  government
health care programs, such as Medicare and Medicaid, additional reporting obligations and oversight if we are subject to a
corporate  integrity  agreement  or  other  agreement  to  resolve  allegations  of  non-compliance  with  these  laws,  and  the
curtailment or restructuring of our operations.

Risks Related to Ownership of Our Common Stock

The trading price of the shares of our common stock has been and is likely to continue to be volatile.

Our stock price has been and is likely to continue to be volatile. The stock market in general and the market for
biotechnology 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, investors may not be able to sell their common stock at
or  above  the  price  paid  for  the  shares.  The  market  price  for  our  common  stock  may  be  influenced  by  many  factors,
including:

● the  commencement,  enrollment  or  results  of  any  clinical  trials  we  may  conduct,  or  changes  in  the

development status of our drug candidates;

50

Table of Contents

● any delay in our regulatory filings for any of our drug 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 from, delays in or termination of clinical trials;
● adverse regulatory decisions, including failure of any of our drug candidates to receive marketing approval;
● unanticipated serious safety concerns related to the use of any drug candidate or previously sold commercial

product;

● changes in financial estimates by us or by any securities analysts who might cover our stock;
● conditions or trends in our industry;
● changes in the structure of health care payment systems;
● changes in the market valuations of similar companies;
● stock market price and volume fluctuations of comparable companies and, in particular, those that operate in

the biotechnology industry;

● publication  of  research  reports  about  us  or  our  industry  or  positive  or  negative  recommendations  or

withdrawal of research coverage by securities analysts;

● announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures;
● announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us;
● investors’ general perception of our company and our business;
● recruitment or departure of key personnel;
● overall performance of the equity markets;
● trading volume of our common stock;
● disputes  or  other  developments  relating  to  proprietary  rights,  including  patents,  litigation  matters  and  our

ability to obtain patent protection for our technologies;

● significant lawsuits, including patent or stockholder litigation;
● general political and economic conditions;
● the evolution of the COVID-19 pandemic and success of mass vaccination efforts; and
● other events or factors, many of which are beyond our control.

In the past, stockholders have initiated class action lawsuits against pharmaceutical companies following periods
of volatility in the market prices of these companies’ stock. For example, two purported class action complaints were filed
against us and certain of our executive officers alleging violations of certain federal securities laws and two stockholder
derivative actions were filed against certain of our executive officers and directors alleging breaches of fiduciary duties. 
We and the other defendants dispute the plaintiffs’ claims and intend to defend these matters vigorously.  We have entered
into indemnification agreements with our executive officers and directors which provide, among other things, that we will
indemnify such officer or director, under the circumstances and to the extent provided for therein, for expenses, damages,
judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be
made  a  party  by  reason  of  his  or  her  position  as  our  director,  officer  or  other  agent,  and  otherwise  to  the  fullest  extent
permitted under Delaware law and our bylaws. These cases, and additional litigation, if instituted against us, could cause us
to incur substantial costs and divert management’s attention and resources from our business.

Sales of a substantial number of shares of our common stock into the market could cause the market price of

our common stock to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. If our
stockholders sell, or the market perceives that our stockholders intend to sell, substantial amounts of our common stock in
the public market, the market price of our common stock could decline significantly.

In addition, we have filed registration statements on Form S-8 under the Securities Act registering the issuance of
shares of common stock subject to options or other equity awards issued or reserved for future issuance under our equity
incentive plans. Shares registered under these registration statements are available for sale in the public market subject to
vesting arrangements and exercise of options, and the restrictions of Rule 144 under the Securities Act in the case of our
affiliates.

Table of Contents

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by
our stockholders to change our management and hinder efforts to acquire a controlling interest in us, and the market
price of our common stock may be lower as a result.

There are provisions in our certificate of incorporation and bylaws that may make it difficult for a third party to
acquire, or attempt to acquire, control of our company, even if a change of control was considered favorable by some or all
of  our  stockholders.  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.

Our charter documents also contain other provisions that could have an anti-takeover effect, including:

● only one of our three classes of directors is elected each year;
● stockholders are not entitled to remove directors other than by a 66 2/3% vote and only for cause;
● stockholders are not permitted to take actions by written consent;
● stockholders cannot call a special meeting of stockholders; and
● stockholders  must  give  advance  notice  to  nominate  directors  or  submit  proposals  for  consideration  at

stockholder meetings.

In  addition,  we  are  subject  to  the  anti-takeover  provisions  of  Section  203  of  the  Delaware  General  Corporation
Law,  which  regulates  corporate  acquisitions  by  prohibiting  Delaware  corporations  from  engaging  in  specified  business
combinations  with  particular  stockholders  of  those  companies.  These  provisions  could  discourage  potential  acquisition
proposals  and  could  delay  or  prevent  a  change  of  control  transaction.  They  could  also  have  the  effect  of  discouraging
others from making tender offers for our common stock, including transactions that may be in your best interests. These
provisions may also prevent changes in our management or limit the price that investors are willing to pay for our stock.

We are a “smaller reporting company” and, as a result of the reduced disclosure and governance requirements

applicable to smaller reporting companies, our common stock may be less attractive to investors.

We  are  a  “smaller  reporting  company”  as  defined  in  Item  10(f)(1)  of  Regulation  S-K,  and  we  intend  to  take
advantage of some of the exemptions from reporting requirements that are applicable to other public companies that are not
smaller reporting companies, including:

● not  being  required  to  comply  with  the  auditor  attestation  requirements  in  the  assessment  of  our  internal

control over financial reporting; and

● reduced  disclosure  obligations  regarding  executive  compensation  in  our  periodic  reports,  proxy  statements

and registration statements.

We  may  take  advantage  of  these  reporting  exemptions  until  we  are  no  longer  a  smaller  reporting  company.  We
will remain a smaller reporting company until the last day of any fiscal year for so long as either (1) the market value of
our shares of common stock held by non-affiliates does not equal or exceed $250.0 million as of the prior June 30th, or (2)
our annual revenues did not equal or exceed $100.0 million during such completed fiscal year and the market value of our
shares of common stock held by non-affiliates did not equal or exceed $700.0 million as of the prior June 30th.

We  cannot  predict  if  investors  will  find  our  common  stock  less  attractive  because  we  will  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.

If  we  fail  to  maintain  proper  and  effective  internal  controls,  our  ability  to  produce  accurate  financial

statements on a timely basis could be impaired.

We  are  subject  to  the  reporting  requirements  of  the  Exchange  Act,  the  Sarbanes-Oxley  Act  and  the  rules  and

regulations of the stock market on which our common stock is listed. The Sarbanes-Oxley Act requires, among other

52

Table of Contents

things,  that  we  maintain  effective  disclosure  controls  and  procedures  and  internal  control  over  financial  reporting,  and
perform system and process evaluation and testing of our internal control over financial reporting to allow management to
report on the effectiveness of our internal control over financial reporting. This requires that we incur substantial additional
professional  fees  and  internal  costs  to  expand  our  accounting  and  finance  functions  and  that  we  expend  significant
management efforts.

We may identify weaknesses in our system of internal financial and accounting controls and procedures that could
result in a material misstatement of our consolidated financial statements. Our internal control over financial reporting will
not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only
reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in
all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will
not occur or that all control issues and instances of fraud will be detected.

If  we  are  unable  to  maintain  proper  and  effective  internal  controls,  we  may  not  be  able  to  produce  timely  and
accurate financial statements, and we may conclude that our internal control over financial reporting is not effective. If that
were to happen, the market price of our stock could decline, and we could be subject to sanctions or investigations by the
stock exchange on which our common stock is listed, the SEC, or other regulatory authorities.

We might not be able to utilize a significant portion of our net operating loss carryforwards and research and

development tax credit carryforwards.

As of December 31, 2020, we had federal and state net operating loss carryforwards, or NOLs, of $367.6 million
and  $369.6  million,  respectively,  which  will  begin  to  expire  in  2032.    Under  the  2017  Tax  Act,  as  modified  by  the
Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, federal NOL carryforwards generated in tax years
beginning after December 31, 2017 may be carried forward indefinitely but, in the case of tax years beginning after 2020,
may  only  be  used  to  offset  80%  of  our  taxable  income  annually.  Federal  NOL  carryforwards  generated  in  taxable  years
beginning in 2018, 2019 and 2020 will similarly carry forward indefinitely but will not be subject to such 80% of annual
taxable income limitation.  It is uncertain if and to what extent various states will conform to the federal tax law.  As of
December  31,  2020,  we  also  had  federal  research  and  development  tax  credit  carryforwards  of  $8.6  million  which  will
begin to expire in 2032, and state research and development tax credit carryforwards of $0.1 million which will begin to
expire  in  2022.  We  also  have  $0.2  million  of  loss  carryforwards  in  the  United  Kingdom  which  can  be  carried  forward
indefinitely.  These  net  operating  loss  and  tax  credit  carryforwards  could  expire  unused  or  due  to  limitation  on  use  be
unavailable to offset future income tax liabilities.  In addition, under Section 382 of the Internal Revenue Code of 1986, as
amended, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally
defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to
use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income may
be limited.  We have completed an analysis under Section 382 for NOLs generated from July 13, 2012 through July 20,
2020.  Although we have experienced Section 382 ownership changes since 2012, we have concluded that we should have
sufficient  ability  to  utilize  NOLs  accumulated  during  the  periods  tested.    We  have  not  yet  determined  if  a  Section  382
ownership change has occurred after July 20, 2020.  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. If we determine that an
ownership  change  has  occurred  and  our  ability  to  use  our  historical  net  operating  loss  and  tax  credit  carryforwards  is
materially limited, it might harm our future operating results by effectively increasing our future tax obligations.

We do not anticipate paying any cash dividends on our common stock in the foreseeable future and our stock

may not appreciate in value.

We  have  not  declared  or  paid  cash  dividends  on  our  common  stock  to  date.  We  currently  intend  to  retain  our
future  earnings,  if  any,  to  fund  the  development  and  growth  of  our  business.  There  is  no  guarantee  that  shares  of  our
common stock will appreciate in value or that the price at which our stockholders have purchased their shares will be able
to be maintained.

Exclusive forum provisions in our amended and restated certificate of incorporation and amended and restated
bylaws could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors,
officers or other employees.

Our  amended  and  restated  certificate  of  incorporation  provides  that  the  Court  of  Chancery  of  the  State  of
Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common
law: (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim for breach of a fiduciary
duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a claim
arising  pursuant  to  any  provision  of  the  Delaware  General  Corporation  Law,  our  amended  and  restated  certificate  of
incorporation  or  our  amended  and  restated  bylaws  or  (iv)  any  action  asserting  a  claim  governed  by  the  internal  affairs
doctrine.  This  provision  would  not  apply  to  suits  brought  to  enforce  a  duty  or  liability  created  by  the  Exchange  Act.
Furthermore,  Section  22  of  the  Securities  Act  creates  concurrent  jurisdiction  for  federal  and  state  courts  over  all  such
Securities  Act  actions.  Accordingly,  both  state  and  federal  courts  have  jurisdiction  to  entertain  such  claims.  To  prevent
having  to  litigate  claims  in  multiple  jurisdictions  and  the  threat  of  inconsistent  or  contrary  rulings  by  different  courts,
among  other  considerations,  our  amended  and  restated  bylaws  provide  the  federal  district  courts  of  the  United  States  of
America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities
Act. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may
nevertheless  seek  to  bring  a  claim  in  a  venue  other  than  those  designated  in  the  exclusive  forum  provisions.  In  such
instance,  we  would  expect  to  vigorously  assert  the  validity  and  enforceability  of  the  exclusive  forum  provisions  of  our
amended  and  restated  certificate  of  incorporation  and  our  amended  and  restated  bylaws.  This  may  require  significant
additional  costs  associated  with  resolving  such  action  in  other  jurisdictions  and  there  can  be  no  assurance  that  the
provisions will be enforced by a court in those other jurisdictions.

Our  amended  and  restated  certificate  of  incorporation  and  amended  and  restated  bylaws  further  provide  any
person or entity purchasing or otherwise acquiring any interest in shares of our common stock is deemed to have notice of
and consented to the foregoing provisions. These exclusive forum provisions 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 other employees, which
may discourage lawsuits against us and our directors, officers and other employees. If a court were to find either exclusive-
forum  provision  to  be  inapplicable  or  unenforceable  in  an  action,  we  may  incur  further  significant  additional  costs
associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.

General Risk Factors

Our  business  and  operations  would  suffer  in  the  event  of  computer  system  failures,  cyber-attacks  or  a

deficiency in our cyber-security.

Despite  the  implementation  of  security  measures,  our  internal  computer  systems,  and  those  of  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  over  the  Internet,  attachments  to  emails,
persons inside our organization, or persons with access to systems inside our organization. The risk of a security breach or
disruption, particularly through cyber-attacks or cyber intrusion, 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. If such an event were to occur and cause interruptions in our operations, it could result in
a  material  disruption  of  our  drug  development  programs.  For  example,  the  loss  of  clinical  trial  data  from  completed  or
ongoing  or  planned  clinical  trials  could  result  in  delays  in  obtaining  marketing  approval  for  our  drug  candidates  and
significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach was to
result  in  a  loss  of  or  damage  to  our  data  or  applications,  or  inappropriate  disclosure  of  confidential  or  proprietary
information, we could incur material legal claims and liability, damage to our reputation, and the further development or
commercialization of our drug candidates by a potential third-party partner could be delayed.

An active trading market for our common stock may not be sustained.

Although our common stock is listed on The Nasdaq Global Select Market, we cannot assure you that an active
trading  market  for  our  shares  will  be  sustained.  If  an  active  market  for  our  common  stock  is  not  sustained,  it  may  be
difficult for investors in our common stock to sell shares without depressing the market price for the shares or to sell the
shares at all.

If  equity  research  analysts  do  not  publish  research  or  reports,  or  publish  unfavorable  research  or  reports,

about us, our business or our market, our stock price and trading volume could decline.

The trading market for our common stock is influenced by the research and reports that equity research analysts
publish  about  us  or  our  business,  our  market  and  our  competitors.  Equity  research  analysts  may  elect  not  to  initiate  or
continue to provide research coverage of our common stock, and such lack of research coverage may adversely affect the
market price of our common stock. Even if we have equity research analyst coverage, we will not have any control over the
analysts or the content and opinions included in their reports. The price of our stock could decline if one or more equity
research analysts downgrade our stock or issue other unfavorable commentary or research. If one or more equity research
analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease,
which in turn could cause our stock price or trading volume to decline. 

The issuance of additional stock in connection with financings, acquisitions, investments, our equity incentive

plan or otherwise will dilute all other stockholders.

Our  certificate  of  incorporation  authorizes  us  to  issue  up  to  100,000,000  shares  of  common  stock  and  up  to
10,000,000  shares  of  preferred  stock  with  such  rights  and  preferences  as  may  be  determined  by  our  board  of  directors.
Subject  to  compliance  with  applicable  rules  and  regulations,  we  may  issue  our  shares  of  common  stock  or  securities
convertible into our common stock from time to time in connection with a financing, acquisition, investment, our equity
incentive plan or otherwise. Any such issuance could result in substantial dilution to our existing stockholders and cause
the trading price of our common stock to decline. 

Changes in tax laws or regulations that are applied adversely to us may have a material adverse effect on our

business, cash flow, financial condition or results of operations.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time,
which could adversely affect our business operations and financial performance. Further, existing tax laws, statutes, rules,
regulations or ordinances could be interpreted, changed, modified or applied adversely to us. For example, the 2017 Tax
Act enacted many significant changes to the U.S. tax laws. Future guidance from the Internal Revenue Service and other
tax authorities with respect to the 2017 Tax Act (as modified by the CARES Act) may affect us, and certain aspects of the
2017 Tax Act could be repealed or modified in future legislation. In addition, it is uncertain if and to what extent various
states will conform to the 2017 Tax Act or any newly enacted federal tax legislation. Changes in corporate tax rates, the
realization  of  net  deferred  tax  assets  relating  to  our  operations,  the  taxation  of  foreign  earnings,  and  the  deductibility  of
expenses under the 2017 Tax Act or future reform legislation could have a material impact on the value of our deferred tax
assets, could result in significant one-time charges, and could increase our future U.S. tax expense.

We incur significant costs and demands upon management as a result of being a public company.

As a public company listed in the United States, we incur, and will continue to incur, particularly after we cease to
be  a  “smaller  reporting  company,”  significant  legal,  accounting  and  other  costs.  These  costs  could  negatively  affect  our
financial  results.  In  addition,  changing  laws,  regulations  and  standards  relating  to  corporate  governance  and  public
disclosure, including regulations implemented by the SEC and The Nasdaq Stock Market, may increase legal and financial
compliance  costs  and  make  some  activities  more  time-consuming.  These  laws,  regulations  and  standards  are  subject  to
varying interpretations and, as a result, their application in practice may evolve over time as new guidance is provided by
regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and standards,
and this investment may result in increased general and administrative expenses and a diversion of management’s time and
attention  from  revenue-generating  activities  to  compliance  activities.  If  notwithstanding  our  efforts  to  comply  with  new
laws, regulations and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us and our
business may be harmed.

Failure  to  comply  with  these  rules  might  also  make  it  more  difficult  for  us  to  obtain  some  types  of  insurance,
including director and officer liability insurance, and we might be forced to accept reduced policy limits and coverage or
incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more
difficult  for  us  to  attract  and  retain  qualified  persons  to  serve  on  our  board  of  directors,  on  committees  of  our  board  of
directors or as members of senior management.

We also sublease 20,433 square feet of office and laboratory space in St. Louis, Missouri, which we use for our
therapeutics and contract research businesses. The sublease has an initial term through June 2029. We have the option to
extend the initial term for two additional five-year periods.

We believe that our facilities are suitable and adequate to meet our current needs.

Item 3. Legal Proceedings

From  time  to  time  we  are  subject  to  litigation  and  claims  arising  in  the  ordinary  course  of  business  including
intellectual property and product liability litigation, but, except as stated below, we are not currently a party to any material
legal  proceedings  and  we  are  not  aware  of  any  other  pending  or  threatened  legal  proceeding  against  us  that  we  believe
could have a material adverse effect on our business, operating results, cash flows or financial condition.

Securities Class Action

On July 30, 2019, plaintiff Linda Rosi, or Rosi, filed a putative class action complaint captioned Rosi v. Aclaris
Therapeutics, Inc., et al.  in  the  U.S.  District  Court  for  the  Southern  District  of  New  York  against  us  and  certain  of  our
executive  officers.    The  complaint  alleges  that  the  defendants  violated  federal  securities  laws  by,  among  other  things,
failing  to  disclose  an  alleged  likelihood  that  regulators  would  scrutinize  advertising  materials  related  to  ESKATA
(hydrogen peroxide) topical solution, 40% (w/w), or ESKATA, our non-marketed FDA-approved product, and find that the
materials  minimized  the  risks  or  overstated  the  efficacy  of  the  product.    The  complaint  seeks  unspecified  compensatory
damages on behalf of Rosi and all other persons and entities that purchased or otherwise acquired our securities between
May 8, 2018 and June 20, 2019.

On September 5, 2019, an additional plaintiff, Robert Fulcher, or Fulcher, filed a substantially identical putative
class action complaint captioned Fulcher v. Aclaris Therapeutics, Inc., et al. in the same court against the same defendants.

On  November  6,  2019,  the  court  consolidated  the  Rosi  and  Fulcher  actions,  or  together,  the  Consolidated

Securities Action, and appointed Fulcher “lead plaintiff” for the putative class.

On  January  24,  2020,  Fulcher  filed  a  consolidated  amended  complaint  in  the  Consolidated  Securities  Action,
naming two additional executive officers as defendants, extending the putative class period to August 12, 2019, and adding
allegations  concerning,  among  other  things,  alleged  statements  and  omissions  throughout  the  putative  class  period
concerning  ESKATA’s  risks,  tolerability  and  effectiveness.  The  defendants  filed  a  motion  to  dismiss  the  consolidated
amended  complaint  on  April  17,  2020.  Fulcher  filed  an  opposition  to  the  defendants’  motion  on  June  15,  2020,  and  the
defendants  filed  a  reply  to  such  opposition  on  August  4,  2020.  Oral  argument  on  the  pending  motion  to  dismiss  is
scheduled for February 25, 2021. The motion remains under judicial consideration.

We and the other defendants dispute plaintiffs’ claims in the Consolidated Securities Action and intend to defend

the matter vigorously.

Stockholder Derivative Action

On November 15, 2019, plaintiff Keith Allred, or Allred, filed a derivative stockholder complaint captioned Allred

v. Walker et al. in the U.S. District Court for the Southern District of New York against certain of our

56

 
Table of Contents

directors and executive officers.  The complaint alleges that the defendants, among other things, breached their fiduciary
duties  as  directors  and/or  officers  in  connection  with  the  claims  alleged  in  the  Consolidated  Securities  Action.    The
complaint seeks, among other things, unspecified compensatory damages on behalf of our company.

On November 25, 2019, an additional plaintiff, Bruce Brown, or Brown, filed a substantially identical complaint

captioned Brown v. Walker et al. in the same court against the same defendants.

On  December  12,  2019,  the  court  consolidated  the  Allred  and  Brown  actions  under  the  caption  In  re  Aclaris
Therapeutics, Inc. Derivative Litigation, or the Consolidated Derivative Action, and directed that future derivative cases
filed in or transferred to the court arising out of substantially the same transactions or events be similarly consolidated. 
Thereafter,  on  January  11,  2020,  the  court  stayed  –  subject  to  certain  conditions  –  all  deadlines  in  the  Consolidated
Derivative  Action  pending  resolution  of  the  defendants’  then-anticipated  motion  to  dismiss  the  Consolidated  Securities
Action.

The defendants dispute plaintiffs’ claims in the Consolidated Derivative Action and intend to defend the matter

vigorously.

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  in
conjunction  with  the  consolidated  financial  statements  and  the  related  notes  to  those  statements  included  later  in  this
Annual  Report.  In  addition  to  historical  financial  information,  the  following  discussion  contains  forward-looking
statements that reflect our plans, estimates, beliefs and expectations that involve risks and uncertainties. Our actual results
and  the  timing  of  events  could  differ  materially  from  those  discussed  in  these  forward-looking  statements.  Factors  that
could  cause  or  contribute  to  these  differences  include  those  discussed  below  and  elsewhere  in  this  Annual  Report,
particularly in Part I, Item 1A. “Risk Factors,” and “Special Note Regarding Forward-Looking Statements.”

Overview

We  are  a  clinical-stage  biopharmaceutical  company  focused  on  developing  novel  drug  candidates  for  immuno-
inflammatory  diseases.    In  addition  to  developing  our  novel  drug  candidates,  we  are  pursuing  strategic  alternatives,
including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our novel drug candidates.

ATI-450, an Investigational Oral MK2 Inhibitor

We  submitted  an  Investigational  New  Drug  Application,  or  IND,  in  April  2019  for  ATI-450,  an  investigational
oral,  novel,  small  molecule  selective  mitogen-activated  protein  kinase-activated  protein  kinase  2,  or  MK2,  inhibitor
compound,  for  the  treatment  of  rheumatoid  arthritis,  which  was  allowed  by  the  U.S.  Food  and  Drug  Administration,  or
FDA,  in  May  2019.    MK2  is  a  key  regulator  of  pro-inflammatory  mediators  including  TNFα,  IL1β,  IL6,  IL8  and  other
essential pathogenic signals in chronic immuno-inflammatory diseases, as well as in oncology.  As an oral drug candidate,
we  are  developing  ATI-450  as  a  potential  alternative  to  injectable  anti-TNF/IL1/IL6  biologics  and  JAK  inhibitors  for
treating certain immuno-inflammatory diseases.

We initiated a Phase 1 single (at 10mg, 30mg, 50mg and 100mg doses) and multiple ascending (at 10mg, 30mg
and 50mg doses) dose clinical trial evaluating ATI-450 in 77 healthy subjects in August 2019 (ATI-450-PKPD-101). Final
data from this trial demonstrated that ATI-450 resulted in marked inhibition of TNFα, IL1β, IL8 and IL6. We also observed
that ATI-450 had dose-proportional pharmacokinetics with a terminal half-life of 9-12 hours in the multiple ascending dose
cohort,  and  had  no  meaningful  food  effect  or  drug-drug  interaction  with  methotrexate.    ATI-450  was  generally  well-
tolerated at all doses tested in the trial.  The most common adverse events (reported by 2 or more subjects who received
ATI-450) were dizziness, headache, upper respiratory tract infection, constipation, abdominal pain and nausea. 

ATI-450  was  also  evaluated  at  80mg  and  120mg  doses  twice  daily  in  a  second  Phase  1  clinical  trial  in  healthy
subjects  (ATI-450-PKPD-102).  Preliminary  topline  data  from  this  trial  showed  that  no  dose-limiting  toxicity  was
observed. Ex vivo analysis of blood samples from this Phase 1 trial showed that increased cytokine inhibition was achieved
with these higher doses of ATI-450. No serious adverse events were reported and all adverse events were mild to moderate.
The  most  common  adverse  events  (reported  by  2  or  more  subjects  who  received  ATI-450)  were  headache,  dizziness,
nausea, parasthesia and, in the post-dosing safety follow-up phase of the trial, dry skin. These adverse events were all mild
in severity. A final analysis of this trial is underway.

Moderate to Severe Rheumatoid Arthritis

Following  the  completion  of  the  first  Phase  1  clinical  trial,  in  March  2020  we  initiated  a  12-week,  Phase  2a,
multicenter, randomized, investigator and patient-blind, sponsor-unblinded, parallel group, placebo-controlled clinical trial
to  investigate  the  safety,  tolerability,  pharmacokinetics  and  pharmacodynamics  of  ATI-450  in  subjects  with  moderate  to
severe rheumatoid arthritis (ATI-450-RA-201). In the trial, 19 subjects were randomized in a 3:1 ratio (seventeen subjects
[15 in the treatment arm and two in the placebo arm] completed treatment) and received either ATI-450 at 50 mg twice
daily or placebo, in combination with methotrexate, for 12 weeks. Preliminary topline data from this trial showed that ATI-
450  demonstrated  durable  clinical  activity,  as  defined  by  a  marked  and  sustained  reduction  in  DAS28-CRP  and
improvement  of  ACR20/50/70  responses  over  12  weeks.  ATI-450  was  generally  well  tolerated.  All  adverse  events  were
mild  to  moderate.  The  most  common  adverse  events  (each  reported  in  2  subjects)  were  urinary  tract  infection,  or  UTI,
elevated lipids and ventricular extrasystoles, all of which were determined to be unrelated to treatment except for one UTI.
Two subjects withdrew from the trial, one in the treatment arm and one in the placebo arm. The subject in the treatment
arm withdrew due to palpitations, which were unrelated to the trial medication, and an elevated creatine phosphokinase,

59

Table of Contents

or CPK, which was determined by the site investigator to be treatment-related. The subject in the placebo arm withdrew as
a result of prohibited medication needed to treat muscle strain. There was one non-treatment-related serious adverse event
(COVID-19)  reported  in  the  four-week  safety  follow-up  phase  of  the  trial  in  a  subject  who  was  no  longer  receiving
treatment.

An interim analysis (11 treatment, two placebo) of ex vivo stimulated cytokines from blood samples taken from
the treatment arm showed a marked and durable inhibition of TNFα, IL1β, IL6, and IL8 over the 12 week dosing period.
Similarly, analysis of endogenous inflammation biomarkers also demonstrated a marked and sustained inhibition of median
concentrations of hsCRP, TNFα, IL6, IL8 and MIP1β in the treatment arm over the 12-week period.

We plan to submit for publication a full analysis of the Phase 2a data in a peer-reviewed scientific journal which
will  include  data  from  other  secondary  and  exploratory  endpoints  evaluated  in  the  trial,  including  the  four-week  safety
follow-up data and a full analysis of MRI, pharmacodynamic and pharmacokinetic data. Based on the results observed in
the  Phase  2a  trial,  we  intend  to  progress  ATI-450  into  a  Phase  2b  trial  in  moderate  to  severe  rheumatoid  arthritis  in  the
second half of 2021.

Cryopyrin-associated Periodic Syndrome

In  November  2020,  we  initiated  a  Phase  2a  multicenter,  open-label,  single-arm  clinical  trial  to  investigate  the
safety,  tolerability,  efficacy  and  pharmacodynamics  of  ATI-450  for  the  maintenance  of  remission  in  subjects  with
cryopyrin-associated periodic syndrome, or CAPS, previously managed with anti-IL1 therapy (ATI-450-CAPS-201). Due
to the COVID-19 pandemic, subject enrollment in this trial was paused. As a result of the ongoing pandemic and given the
positive  preliminary  topline  data  from  the  ATI-450-RA-201  trial,  we  have  decided  to  focus  our  efforts  and  resources  on
other immuno-inflammatory diseases.

ATI-1777, an Investigational Topical “Soft” JAK 1/3 Inhibitor

In June 2020, we submitted an IND for ATI-1777, an investigational topical “soft” JAK 1/3 inhibitor compound,
for the treatment of moderate to severe atopic dermatitis. “Soft” JAK inhibitors are designed to be topically applied and
active  in  the  skin,  but  rapidly  metabolized  and  inactivated  when  they  enter  the  bloodstream,  which  may  result  in  low
systemic exposure.

In  October  2020,  we  initiated  a  Phase  2a,  multicenter,  randomized,  double-blind,  vehicle-controlled,  parallel-
group  clinical  trial  to  determine  the  efficacy,  safety,  tolerability  and  pharmacokinetics  of  ATI-1777  in  subjects  with
moderate to severe atopic dermatitis (ATI-1777-AD-201). We expect data to be available mid-year 2021.

ATI-2138, an Investigational ITJ Inhibitor

We  are  also  developing  ATI-2138,  an  investigational  oral  ITK/TXK/JAK3,  or  ITJ,  inhibitor  compound,  as  a
potential treatment for psoriasis and/or inflammatory bowel disease, which are both T-cell mediated autoimmune diseases.
  The  ITJ  compound  interrupts  T  cell  signaling  through  the  combined  inhibition  of  ITK/TXK/JAK3  pathways  in
lymphocytes. We expect to file an IND for ATI-2138 in the second half of 2021.

Our Other Drug Candidates

We continue to seek third-party partners for our dermatology investigational drug candidate A-101 45% Topical

Solution as a potential treatment for common warts (verruca vulgaris).

Financial Overview

Since our inception, we have incurred significant operating losses.  Our net loss was $51.0 million for the year
ended December 31, 2020 and $161.4 million for the year ended December 31, 2019.  As of December 31, 2020, we had an
accumulated  deficit  of  $504.5  million.   We  expect  to  incur  significant  expenses  and  operating  losses  for  the  foreseeable
future as we advance our drug candidates from discovery through preclinical and clinical development.  In addition, our
drug candidates, even if they are approved by regulatory agencies for marketing, may not achieve commercial success.  We
may  also  not  be  successful  in  pursuing  strategic  alternatives,  including  identifying  and  consummating  transactions  with
third-party partners, to further develop, obtain marketing approval for and/or commercialize our drug

60

candidates.  Furthermore, we have incurred and expect to continue to incur significant costs associated with operating as a
public company, including legal, accounting, investor relations and other expenses.  As a result, we will need substantial
additional funding to support our continuing operations.

We have historically financed our operations primarily with sales of equity securities and incurring indebtedness
in the form of loans from commercial lenders.  In the near term, we expect to finance our operations through these and
other  capital  sources,  including  potential  partnerships  with  other  companies  or  other  strategic  transactions.    We  may  be
unable  to  raise  additional  funds  or  enter  into  such  other  agreements  or  arrangements  when  needed  on  commercially
acceptable terms, or at all.  If we fail to raise capital or enter into such agreements as, and when, needed, we may have to
significantly delay, scale back or discontinue the development of one or more of our drug candidates.  

Recent Developments

January 2021 Public Offering

In January 2021, we closed a public offering in which we sold 6,306,271 shares of common stock at a price to the
public  of  $17.50  per  share,  for  aggregate  gross  proceeds  of  $110.4  million.  We  paid  underwriting  discounts  and
commissions of $6.6 million, and also incurred expenses of $0.3 million in connection with the offering.  As a result, the
net  offering  proceeds  received  by  us,  after  deducting  underwriting  discounts,  commissions  and  offering  expenses,  were
$103.5 million.

Impact of COVID-19 on Our Business

The  impacts  of  the  global  COVID-19  pandemic  continue  to  evolve.  We  have  implemented  a  virtual  operations
strategy, including teleworking and other alternative work arrangements for our employees, intended to protect the health
and safety of our employees while enabling us to continue to develop our drug candidates and provide contract research
services  to  our  clients.  We  are  focused  on  ensuring  the  continuity  of  our  operations.  However,  COVID-19  has  caused
disruptions to our business. For example, due to the COVID-19 pandemic subject enrollment in our ATI-450-CAPS-201
trial was paused as a result of which, among other reasons, we have decided to focus our efforts and resources on other
immuno-inflammatory diseases.

If  COVID-19  continues  to  spread,  we  may  experience  additional  disruptions  that  could  severely  impact  our
business,  results  of  operations  and  prospects,  including  the  timing  of  our  development  programs  and  our  clinical  trials,
including  our  trials  of  ATI-450  as  a  potential  treatment  for  moderate  to  severe  rheumatoid  arthritis  and  ATI-1777  as  a
potential  treatment  for  moderate  to  severe  atopic  dermatitis.  The  extent  to  which  the  COVID-19  pandemic  impacts  our
business, our preclinical and clinical development and our regulatory efforts will depend on future developments that are
highly uncertain and cannot be predicted, such as the geographic spread of the disease, the duration of the outbreak, travel
restrictions, quarantines, stay-at-home orders, social distancing requirements, business closures and supply chain and other
disruptions in the United States and other countries, and the effectiveness of actions taken in the United States and other
countries to contain and treat the disease, including the administration of vaccines.  Accordingly, we do not yet know the
full extent of the potential impacts on our business, our preclinical and clinical development and regulatory activities.

Acquisition and License Agreements

Agreement and Plan of Merger with Confluence

In  August  2017,  we  entered  into  an  Agreement  and  Plan  of  Merger,  or  the  Confluence  Agreement,  with
Confluence Life Sciences, Inc. (now known as Aclaris Life Sciences, Inc.), or Confluence, Aclaris Life Sciences, Inc., our
wholly-owned subsidiary, or Merger Sub, and Fortis Advisors LLC, as representative of the equity holders of Confluence.
 Pursuant to the terms of the Confluence Agreement, the Merger Sub merged with and into Confluence, with Confluence
surviving  as  our  wholly-owned  subsidiary.  We  paid  closing  consideration  of  $10.3  million  in  cash  and  issued  349,527
shares of our common stock with a fair value of $9.7 million to the former Confluence equity holders. 

In November 2018, a development milestone specified in the Confluence Agreement was achieved, as a result of
which we paid the former Confluence equity holders $2.5 million in cash and issued 253,208 shares of our common stock
with a fair value of $2.2 million.  Under the Confluence Agreement, we also agreed to pay the former Confluence equity
holders aggregate remaining contingent consideration of up to $75.0 million based upon the achievement of specified

61

Table of Contents

regulatory  and  commercial  milestones  set  forth  in  the  Confluence  Agreement.    In  addition,  we  have  agreed  to  pay  the
former Confluence equity holders future royalty payments calculated as a low single-digit percentage of annual net sales,
subject to specified reductions, limitations and other adjustments, until the date that all of the patent rights for that product
have expired, as determined on a country-by-country and product-by-product basis or, in specified circumstances, ten years
from the first commercial sale of such product.  In addition to the payments described above, if we sell, license or transfer
any of the intellectual property acquired from Confluence pursuant to the Confluence Agreement to a third party, we will
be obligated to pay the former Confluence equity holders a portion of any consideration received from such sale, license or
transfer in specified circumstances.  

Asset Purchase Agreement with EPI Health

In October 2019, we entered into an asset purchase agreement with EPI Health, LLC, or EPI Health, pursuant to
which  we  sold  the  worldwide  rights  to  RHOFADE  (oxymetazoline  hydrochloride)  cream,  1%,  or  RHOFADE,  which
included the assignment of certain licenses for related intellectual property assets, or the Disposition.  

Pursuant to the asset purchase agreement, EPI Health paid us an upfront payment of $35.0 million, $1.75 million
of which was placed in escrow, and $0.2 million for inventory.  In addition, EPI Health has agreed to pay us (i) potential
sales milestone payments of up to $20.0 million in the aggregate upon the achievement of specified levels of net sales of
products covered by the agreement, (ii) a specified high single-digit royalty calculated as a percentage of net sales, on a
product-by-product and country-by-country basis, until the date that the patent rights related to a particular product, such as
RHOFADE,  have  expired,  provided,  that  with  respect  to  sales  of  RHOFADE  in  any  territory  outside  of  the  United
States,  such  royalty  shall  be  paid  on  a  country-by-country  basis  until  the  date  that  the  RHOFADE  patent  rights  in  the
particular  country  have  expired  or,  if  later,  10  years  from  the  date  of  the  first  commercial  sale  of  RHOFADE  in  such
country  and  (iii)  25%  of  any  upfront,  license,  milestone,  maintenance  or  fixed  payment  received  by  EPI  Health  in
connection with any license or sublicense of the assets transferred in the Disposition in any territory outside of the United
States,  subject  to  specified  exceptions.    In  addition,  EPI  Health  has  agreed  to  assume  our  obligation  to  pay  specified
royalties and milestone payments under certain agreements with third parties.

Asset Purchase Agreement with Allergan

In November 2018, we acquired RHOFADE, which included an exclusive license to certain intellectual property
for  RHOFADE,  as  well  as  additional  intellectual  property,  from  Allergan  Sales,  LLC,  or  Allergan,  pursuant  to  an  asset
purchase agreement. At the closing of the acquisition, we paid total cash consideration of $66.1 million.

Components of Our Results of Operations

Revenue

Product Sales, net

We  sold  RHOFADE  in  the  United  States  during  the  years  ended  December  31,  2019  and  2018.    We  relied  on
Allergan  to  distribute  RHOFADE  on  our  behalf  pursuant  to  the  terms  of  a  transition  services  agreement.    We  sold
RHOFADE  to  wholesalers  in  the  United  States,  which,  in  turn,  distributed  it  to  pharmacies  that  ultimately  filled  patient
prescriptions.  We also entered into, or were subject to, arrangements with third-party payors, including pharmacy benefit
managers and government agencies, as well as group purchasing organizations, or GPOs, which provided for government
mandated  or  privately  negotiated  rebates,  chargebacks,  and  discounts  with  respect  to  the  purchase  of  RHOFADE.    We
never sold RHOFADE outside of the United States.  We sold the worldwide rights to RHOFADE to EPI Health in October
2019.  

During  the  years  ended  December  31,  2019  and  2018,  we  sold  ESKATA  (hydrogen  peroxide)  topical  solution,
40%  (w/w),  or  ESKATA,  our  non-marketed  FDA-approved  product,  to  one  wholesaler,  McKesson  Specialty  Care
Distribution, or McKesson, which in turn resold ESKATA to health care providers.  We also entered into agreements with
two  GPOs  that  provided  for  administrative  fees  and  discounted  pricing  in  the  form  of  volume-based  rebates  and
chargebacks.  We never sold ESKATA outside of the United States.  We discontinued sales of ESKATA in the United States
in August 2019.

Contract Research

We  earn  revenue  from  the  provision  of  laboratory  services  to  clients  through  Confluence,  our  wholly-owned
subsidiary.  Contract research revenue is generally evidenced by contracts with clients which are on an agreed upon fixed-
price, fee-for-service basis and are generally billed on a monthly basis in arrears for services rendered.

We  have  also  received  revenue  from  grants  under  the  Small  Business  Innovation  Research  program  of  the
National  Institutes  of  Health,  or  NIH.    During  the  year  ended  December  31,  2018,  we  had  two  active  grants  from  NIH
related to early-stage research.  There are no remaining funds available to us under the grants.  

Cost of Revenue

Cost of revenue consists of the costs incurred in connection with the provision of contract research services to our

clients through Confluence.  Cost of revenue primarily includes:

● employee-related expenses, which include salaries, benefits and stock-based compensation;
● outsourced professional scientific services;
● depreciation of laboratory equipment;
● facility-related costs; and
● laboratory materials and supplies used to support the services provided.

Research and Development Expenses

Research  and  development  expenses  consist  of  expenses  incurred  in  connection  with  the  discovery  and

development of our drug candidates. These expenses primarily include:

● expenses incurred under agreements with contract research organizations, or CROs, as well as clinical trial
sites and consultants that conduct our clinical trials and preclinical studies, and investigator-initiated trials;

● manufacturing scale-up expenses and the cost of acquiring and manufacturing active pharmaceutical

ingredients and preclinical and clinical trial materials;
● outsourced professional scientific development services;
● medical affairs expenses related to our drug candidates;
● employee-related expenses, which include salaries, benefits and stock-based compensation;
● depreciation of manufacturing equipment;
● payments made under agreements with third parties under which we have acquired or licensed intellectual

property;

● expenses relating to regulatory activities, including filing fees paid to regulatory agencies;
● laboratory materials and supplies used to support our research activities; and
● non-cash charges related to the revaluation of contingent consideration.

Research and development activities are central to our business model.  Drug candidates in later stages of clinical
development generally have higher development costs than those in earlier stages of clinical development, primarily due to
the  increased  size  and  duration  of  later-stage  clinical  trials.  We  expect  to  continue  to  incur  research  and  development
expenses  in  the  near  term  as  we  continue  the  clinical  development  of  ATI-450  as  a  potential  treatment  for  moderate  to
severe rheumatoid arthritis and potentially other immuno-inflammatory diseases and ATI-1777 as a potential treatment for
moderate to severe atopic dermatitis, continue the development of our preclinical compounds, and continue to discover and
develop  additional  drug  candidates.    We  expense  research  and  development  costs  as  incurred.    Our  direct  research  and
development  expenses  primarily  consist  of  external  costs  including  fees  paid  to  CROs,  consultants,  investigator  sites,
regulatory  agencies  and  third  parties  that  manufacture  our  preclinical  and  clinical  trial  materials,  and  are  tracked  on  a
program-by-program basis.  We do not allocate personnel costs, facilities or other indirect expenses, to specific research
and development programs.

The successful development of our drug candidates is highly uncertain. We cannot reasonably estimate or know
the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of, or when,
if ever, material net cash inflows may commence from any of our drug candidates. This uncertainty is due to the numerous

63

Table of Contents

risks  and  uncertainties  associated  with  the  duration  and  cost  of  clinical  trials,  which  vary  significantly  over  the  life  of  a
project as a result of many factors, including:

● the number of clinical sites included in the trials;
● the length of time required to enroll suitable subjects;
● the number of subjects that ultimately participate in the trials;
● the number of doses subjects receive;
● the impact on the recruitment, enrollment, conduct and timing of our clinical trials due to the COVID-19

pandemic;

● the duration of subject follow-up; and
● the results of our clinical trials.

Our  expenditures  are  subject  to  additional  uncertainties,  including  the  preparation  of  regulatory  filings  for  our
drug  candidates,  and  the  expense  of  filing,  prosecuting,  defending  and  enforcing  any  patent  claims  or  other  intellectual
property rights.  We may obtain unexpected results from our clinical trials or other development activities.  We may elect to
discontinue,  delay  or  modify  the  development,  including  clinical  trials,  of  some  drug  candidates  or  focus  on  others.   A
change  in  the  outcome  of  any  of  these  variables  with  respect  to  the  development  of  a  drug  candidate  could  mean  a
significant change in the costs and timing associated with the development of that drug candidate.  For example, if the FDA
or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently anticipate, or if
we  experience  significant  delays  in  enrollment  in  any  of  our  clinical  trials,  we  could  be  required  to  expend  significant
additional financial resources and time on the completion of clinical development.  

General and Administrative Expenses

General  and  administrative  expenses  consist  principally  of  salaries  and  related  costs,  including  stock-based
compensation, for personnel in executive, administrative, finance and legal functions.  General and administrative expenses
also include facility-related costs, patent filing and prosecution costs, professional fees for legal, auditing and tax services,
investor relations costs, insurance costs, travel expenses, as well as a milestone payment under a third party agreement.

Other Income (Expense), net

Other income (expense), net primarily consists of interest earned on our cash, cash equivalents and marketable 
securities, interest expense related to our debt obligations, and gains and losses on transactions denominated in foreign 
currencies.  

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in
the  United  States.  The  preparation  of  our  consolidated  financial  statements  and  related  disclosures  requires  us  to  make
estimates  and  judgments  that  affect  the  reported  amounts  of  assets  and  liabilities,  disclosure  of  contingent  assets  and
liabilities at the date of the financial statements, and the reported amounts of expenses during the reported period. We base
our estimates on historical experience, known trends and events and various other factors that we believe to be reasonable
under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources. We evaluate our estimates and judgments on an ongoing basis.
Our actual results may differ from these estimates under different assumptions and conditions.  

While our significant accounting policies are described in more detail in the notes to our consolidated financial
statements appearing elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies are
those most critical to the judgments and estimates used in the preparation of our consolidated financial statements.  

Revenue Recognition

We account for revenue in accordance with Accounting Standards Codification, or ASC, Topic 606, Revenue from
Contracts  with  Customers.    Under  ASC  Topic  606,  revenue  is  recognized  when  a  customer  obtains  control  of  promised
goods or services in an amount that reflects the consideration to which we expect to be entitled in exchange for

64

Table of Contents

those goods or services.  

To  determine  revenue  recognition  in  accordance  with  ASC  Topic  606,  we  perform  the  following  five  steps:  (i)
identify  the  contract(s)  with  a  customer,  (ii)  identify  the  performance  obligations  in  the  contract,  (iii)  determine  the
transaction  price,  (iv)  allocate  the  transaction  price  to  the  performance  obligations  in  the  contract,  and  (v)  recognize
revenue when (or as) performance obligations are satisfied.  We recognize revenue when collection of the consideration we
are  entitled  to  under  a  contract  with  a  customer  is  probable.    At  contract  inception,  we  assess  the  goods  or  services
promised within a contract with a customer to identify the performance obligations, and to determine if they are distinct.
 We recognize revenue that is allocated to each distinct performance obligation when (or as) that performance obligation is
satisfied.    We  only  recognize  revenue  when  collection  of  the  consideration  we  are  entitled  to  under  a  contract  with  a
customer is probable.

Product Sales, net

We recognized revenue from product sales at the point the customer obtained control, which generally occurred
upon  delivery.    We  also  included  estimates  of  variable  consideration  in  the  same  period  revenue  was  recognized.
  Components  of  variable  consideration  included  trade  discounts  and  allowances,  product  returns,  government  rebates,
discounts  and  rebates,  other  incentives  such  as  patient  co-pay  assistance,  and  other  fee  for  service  amounts.    Variable
consideration was recorded on the consolidated balance sheet as either a reduction of accounts receivable, if payable to a
customer, or as a current liability, if payable to a third-party other than a customer.  We considered all relevant information
when estimating variable consideration such as contractual and statutory requirements, specific known market events and
trends,  industry  data  and  forecasted  customer  buying  and  payment  patterns.    The  amount  of  net  revenue  that  can  be
recognized  is  constrained  by  estimates  of  variable  consideration  which  are  included  in  the  transaction  price.    Payment
terms  with  customers  did  not  exceed  one  year  and,  therefore,  we  did  not  account  for  a  financing  component  in  our
arrangements.  We expensed incremental costs of obtaining a contract with a customer, including sales commissions, when
incurred as the period of benefit was less than one year.

Trade Discounts and Allowances - We provided customers with trade discounts, rebates, allowances and/or other
incentives.  We recorded estimates for these items as a reduction of revenue in the same period the revenue was recognized.

Government and Payor Rebates – We contracted with, or were subject to arrangements with, certain third-party
payors,  including  pharmacy  benefit  managers  and  government  agencies,  for  the  payment  of  rebates  with  respect  to
utilization of our commercial products.  We also entered into agreements with GPOs that provided for administrative fees
and discounted pricing in the form of volume-based rebates.  We were also subject to discount and rebate obligations under
state Medicaid programs and Medicare.  We recorded estimates for these discounts and rebates as a reduction of revenue in
the same period the revenue was recognized.  

Other Incentives – We maintained a co-pay assistance program which was intended to provide financial assistance
to  qualified  commercially-insured  patients  with  prescription  drug  co-payments  required  by  third-party  payors.    We
estimated and recorded accruals for these incentives as a reduction of revenue in the period the revenue was recognized.  
Our  estimated  amounts  for  co-pay  assistance  were  based  upon  the  number  of  claims  and  the  cost  per  claim  that  we
expected to receive associated with product that had been sold to customers but remained in the distribution channel at the
end of each reporting period.  

Product Returns - Consistent with industry practice, we have a product returns policy for RHOFADE which may
provide customers a right of return for product purchased within a specified period prior to and subsequent to the product’s
expiration  date.   The  right  of  return  lapses  upon  shipment  of  the  product  to  a  patient.   We  recorded  an  estimate  for  the
amount of product which may be returned as a reduction of revenue in the period the related revenue was recognized.  Our
estimates for product returns were based upon available industry data and our own sales information, including visibility
into the inventory remaining in the distribution channel.  There is no return liability associated with sales of ESKATA as
we had a no returns policy for ESKATA.

Contract Research

Revenue related to laboratory services is generally recognized as the laboratory services are performed, based

65

 
Table of Contents

upon  the  rates  specified  in  the  contracts.    Under  ASC  Topic  606,  we  elected  to  apply  the  “right  to  invoice”  practical
expedient when recognizing contract research revenue and as such, recognize revenue in the amount which we have the
right  to  invoice.   ASC  Topic  606  also  provides  an  optional  exemption,  which  we  have  elected  to  apply,  from  disclosing
remaining  performance  obligations  when  revenue  is  recognized  from  the  satisfaction  of  the  performance  obligation  in
accordance with the “right to invoice” practical expedient.  

We  recognize  revenue  related  to  grants  as  amounts  become  reimbursable  under  each  grant,  which  is  generally

when research is performed, and the related costs are incurred.  

Other Revenue

Licenses of Intellectual Property – We recognize revenue received from non-refundable, upfront fees related to the
licensing  of  intellectual  property  when  the  intellectual  property  is  determined  to  be  distinct  from  the  other  performance
obligations identified in the arrangement, the license has been transferred to the customer, and the customer is able to use
and benefit from the license.

Milestone  Payments  –  At  the  inception  of  each  arrangement  that  includes  milestone  payments,  we  evaluate
whether the milestones are considered probable of being reached and estimate the amount to be included in the transaction
price  using  the  most  likely  amount  method.    If  it  is  probable  that  a  significant  revenue  reversal  would  not  occur,  the
associated milestone value is included in the amount allocated to the license of intellectual property.  Milestone payments
that are not within our control or the control of the customer, such as regulatory approvals, are not considered probable of
being achieved until those approvals are received.

Intangible Assets

Our intangible assets include both definite-lived and indefinite-lived assets.  Our definite-lived intangible assets
consist of a drug discovery platform acquired through the acquisition of Confluence, and prior to the disposition in 2019,
also  included  the  intellectual  property  rights  related  to  RHOFADE.    Definite-lived  intangible  assets  are  amortized  over
their estimated useful life based on the pattern over which the intangible assets are consumed or otherwise used up.  If that
pattern  cannot  be  reliably  determined,  the  straight-line  method  of  amortization  is  used.    Our  indefinite-lived  intangible
assets consist of an in-process research and development, or IPR&D, drug candidate also acquired through the acquisition
of  Confluence.    IPR&D  assets  are  considered  indefinite-lived  until  the  completion  or  abandonment  of  the  associated
research and development efforts.  The cost of IPR&D assets is either amortized over their estimated useful life beginning
when the underlying drug candidate is approved and launched commercially, or expensed immediately if development of
the drug candidate is abandoned.  

Definite-lived intangible assets are tested for impairment when events or changes in circumstances indicate that
the carrying value of the asset may not be recoverable.  Indefinite-lived intangible assets are tested for impairment at least
annually, which we perform during the fourth quarter, or when indicators of an impairment are present.  We recognize an
impairment loss when and to the extent that the estimated fair value of an intangible asset is less than its carrying value.  

During the year ended December 31, 2019, we performed an impairment analysis of the RHOFADE intangible
asset  due  to  our  decision  to  discontinue  commercial  operations  and  actively  seek  a  commercialization  partner  for
RHOFADE.  Our impairment analysis, which primarily utilized a third-party indication of fair value, resulted in a fair value
for the RHOFADE intangible asset which was less than its carrying value.  As a result, we recorded an impairment charge
of $27.6 million to adjust the carrying value of the RHOFADE intangible asset to its net realizable value.  

Goodwill

Goodwill  is  not  amortized,  but  rather  is  subject  to  testing  for  impairment  at  least  annually,  which  we  perform
either  during  the  fourth  quarter  or  when  indicators  of  an  impairment  are  present.    We  consider  each  of  our  operating
segments, therapeutics and contract research, to be a reporting unit since this is the lowest level for which discrete financial
information  is  available.    The  impairment  test  is  a  qualitative  assessment  based  upon  the  then  current  facts  and
circumstances  related  to  operations  of  the  reporting  unit.    If  our  qualitative  assessment  indicates  an  impairment  may  be
present, we would perform the required quantitative analysis and an impairment charge would be recognized to the extent
that the estimated fair value of the reporting unit is less than its carrying amount.  However, any loss recognized would not
exceed the total amount of goodwill allocated to that reporting unit.  

66

Table of Contents

During the year ended December 31, 2019, we performed an impairment analysis due to a decline in our stock
price,  which  was  considered  a  triggering  event  to  evaluate  goodwill  for  impairment.    Our  impairment  analysis,  which
utilized a market approach, noted that our stock price, including a reasonable control premium, resulted in a fair value for
the therapeutics reporting unit which was less than its carrying value.  As a result, we recorded an impairment charge of
$18.5 million.  

Leases

Leases represent a company’s right to use an underlying asset and a corresponding obligation to make payments to
a lessor for the right to use those assets.  We evaluate leases at their inception to determine if they are an operating lease or
a finance lease.  A lease is accounted for as a finance lease if it meets one of the following five criteria: the lease has a
purchase option that is reasonably certain of being exercised, the present value of the future cash flows are substantially all
of the fair market value of the underlying asset, the lease term is for a significant portion of the remaining economic life of
the underlying asset, the title to the underlying asset transfers at the end of the lease term, or if the underlying asset is of
such a specialized nature that it is expected to have no alternative uses to the lessor at the end of the term.  Leases that do
not meet the finance lease criteria are accounted for as an operating lease.  

We recognize assets and liabilities for leases at their inception based upon the present value of all payments due
under  the  lease.    We  use  an  implicit  interest  rate  to  determine  the  present  value  of  finance  leases,  and  our  incremental
borrowing  rate  to  determine  the  present  value  of  operating  leases.    We  determine  incremental  borrowing  rates  by
referencing  collateralized  borrowing  rates  for  debt  instruments  with  terms  similar  to  the  respective  lease.   We  recognize
expense for operating and finance leases on a straight-line basis over the term of each lease, and interest expense related to
finance  leases  is  recognized  over  the  lease  term  based  on  the  effective  interest  method.    We  include  estimates  for  any
residual value guarantee obligations under our leases in lease liabilities recorded on our consolidated balance sheet.  

Right-of-use assets are included in other assets and property and equipment, net on our consolidated balance sheet
for  operating  and  finance  leases,  respectively.    Obligations  for  lease  payments  are  included  in  current  portion  of  lease
liabilities and other liabilities on our consolidated balance sheet for both operating and finance leases.  

Contingent Consideration

We  initially  recorded  a  contingent  consideration  liability  related  to  future  potential  payments  resulting  from  the
acquisition of Confluence based upon the achievement of certain development, regulatory and commercial milestones, as
well as future projected sales performance, at its estimated fair value on the date of acquisition.  The ultimate amount of
future payments, if any, is based on criteria such as sales performance and the achievement of certain regulatory and sales
milestones.   We  estimate  the  fair  value  of  the  contingent  consideration  liability  related  to  the  achievement  of  regulatory
milestones  by  assigning  an  achievement  probability  to  each  potential  milestone  and  discounting  the  associated  cash
payment  to  its  present  value  using  a  credit-risk-adjusted  interest  rate.    We  estimate  the  fair  value  of  the  contingent
consideration  liability  associated  with  sales  milestones  and  royalties  by  estimating  future  sales  levels,  assigning  an
achievement probability and discounting the associated cash payment amounts to their present values using a risk-adjusted
rate of return.  Significant assumptions used in our estimates include the probability of success of both achieving regulatory
milestones and commencing commercialization, which are based upon an asset’s current stage of development and ranged
between 4% and 15%.  We evaluate fair value estimates of contingent consideration liabilities on a quarterly basis.  Any
change in fair value reflects new information about the likelihood of the payment of the contingent consideration and the
passage  of  time.  For  example,  if  the  timing  of  the  development  of  an  acquired  drug  candidate,  or  the  size  of  potential
commercial  opportunities  related  to  an  acquired  drug  candidate,  differ  from  our  assumptions,  then  the  fair  value  of
contingent consideration would be adjusted accordingly. Future changes in the fair value of the contingent consideration, if
any, will be recorded as income or expense in our consolidated statement of operations.  

During the year ended December 31, 2020, we updated our assumptions for contingent consideration related to the
acquisition of Confluence as a result of the successful completion of a Phase 1 clinical trial for ATI-450 and the submission
and allowance of an IND for ATI-1777, which resulted in a charge of $2.4 million.  During the year ended December 31,
2019, we updated our assumptions for contingent consideration related to the acquisition of Confluence as a result of the
submission and allowance of an IND for ATI-450, which resulted in a charge of $0.7 million.

Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our research
and development expenses.  This process involves reviewing open contracts and purchase orders, communicating with our
applicable  personnel  to  identify  services  that  have  been  performed  on  our  behalf  and  estimating  the  level  of  service
performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of
actual costs. The majority of our preclinical development activities and clinical trials are performed pursuant to quotes and
contracts with multiple vendors, including research institutions and CROs, that conduct and manage such activities on our
behalf.  Many of the contracts with our vendors require advance payments; while others invoice us in arrears for services
performed, or on a pre-determined schedule, or upon the successful enrollment of subjects, or when contractual milestones
are met.  We record expenses for preclinical development activities and clinical trials based upon estimates of the total cost
of  the  services  to  be  provided  by  the  vendor  and  the  time  period  over  which  the  vendor  is  to  perform  those  services.
 Estimates of research and development expenses included in our consolidated financial statements are based on facts and
circumstances  known  to  us  at  that  time.  The  financial  terms  of  our  agreements  are  subject  to  negotiation,  vary  from
contract  to  contract,  and  may  result  in  uneven  payment  flows.    There  may  be  times  when  payments  made  to  a  vendor
exceed the level of services provided, resulting in a prepayment for work to be performed.  We may confirm the accuracy
of  our  estimates  with  the  service  providers,  or  make  adjustments  to  our  estimates  based  upon  new  or  updated  facts  and
circumstances, as necessary.  For example, if the timing and/or cost of services to be performed is materially different from
our previous estimates, we would make a prospective adjustment for the change in our estimates in the period in which we
become  aware  of  the  new  cost  and/or  timing.  Although  we  do  not  expect  our  estimates  to  be  materially  different  from
actual amounts incurred, our understanding of the status and timing of services performed relative to the actual status and
timing of services performed may vary and may result in reporting amounts that are too high or too low in any particular
period.  To date, we have not made any material adjustments to our estimates of research and development expenses.  

Stock-Based Compensation

We measure the compensation expense of stock-based awards granted to employees and directors using the grant
date fair value of the award.  We have issued stock options and restricted stock unit, or RSU, awards with service-based
vesting conditions, as well as with performance-based vesting conditions.  We have not issued awards that include market-
based conditions.  For service-based awards, we recognize stock-based compensation expense on a straight-line basis over
the  requisite  service  period.    For  performance-based  awards,  we  recognize  stock-based  compensation  expense  on  a
straight-line  basis  over  the  requisite  service  period  beginning  in  the  period  that  it  becomes  probable  the  performance
conditions  will  occur.    At  each  balance  sheet  date,  we  evaluate  whether  any  performance  conditions  related  to  a
performance-based award have changed.  The effect of any change in performance conditions would be recognized as a
cumulative catch-up adjustment in the period such change occurs, and any remaining unrecognized compensation expense
would  be  recognized  on  a  straight-line  basis  over  the  remaining  requisite  service  period.    The  impact  of  forfeitures  is
recognized in the period in which they occur.  

We  measure  the  compensation  expense  of  stock-based  awards  granted  to  consultants  using  the  grant  date  fair
value  of  the  award.    We  recognize  compensation  expense  over  the  period  during  which  services  are  rendered  by  the
consultant.

We estimate the fair value of each stock option grant using the Black-Scholes option-pricing model.  We estimate
expected volatility based on historical volatility of a set of peer companies, which are publicly traded, and we expect to
continue to do so until we have adequate historical data regarding the volatility of our own publicly-traded stock price.  The
expected term of our stock options has been determined using the “simplified” method for awards that qualify as “plain
vanilla” options. The expected term of stock options we granted to non-employees is equal to the contractual term of the
option award.  The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of
grant of the award for time periods approximately equal to the expected term of the award.  We use an expected dividend
yield of zero because we have not paid cash dividends to date, and have no intention of paying cash dividends in the future.

The fair value of each RSU is measured using the closing price of our common stock on the date of grant.

Income Taxes

Since our inception, we have not recorded U.S. federal or state income tax benefits for the net operating losses we
have  incurred  in  each  year  or  for  our  earned  research  and  development  tax  credits,  due  to  our  uncertainty  of  realizing  a
benefit from those items.

Contract research revenue was $5.8 million and $4.2 million for the years ended December 31, 2020 and 2019,
respectively, and was comprised primarily of fees earned from the provision of laboratory services to our clients through
Confluence.  Other revenue for the year ended December 31, 2020 consisted of $0.7 million of royalties earned on net sales
of RHOFADE pursuant to the asset purchase agreement with EPI Health.

Cost of Revenue

Cost of revenue was $5.1 million and $4.1 million for the years ended December 31, 2020 and 2019, respectively,
and related to providing laboratory services to our clients through Confluence.  The increase in cost of revenue was driven
primarily by increased personnel and lab supply costs as well as an increase in overhead expenses.

Research and development expenses for ATI-450 during the year ended December 31, 2020 primarily consisted of
costs  associated  with  multiple  clinical  trials,  including  a  Phase  2a  trial  in  subjects  with  moderate  to  severe  rheumatoid
arthritis.    ATI-450  expenses  during  the  year  ended  December  31,  2019  primarily  consisted  of  preclinical  development
activities and activities related to a Phase 1 clinical trial that was completed in January 2020.  ATI-450 expenses increased
during  the  year  ended  December  31,  2020  due  to  an  increase  in  costs  associated  with  various  ongoing  clinical  trials,
partially offset by lower preclinical development activities.  

ATI-1777

Expenses for ATI-1777 were higher during the year ended December 31, 2020 primarily due to costs associated
with  a  Phase  2a  clinical  trial  in  subjects  with  moderate  to  severe  atopic  dermatitis  which  commenced  in  2020,  partially
offset by lower preclinical development activities.

ATI-2138

Expenses  for  ATI-2138  were  higher  during  the  year  ended  December  31,  2020  primarily  due  to  preclinical

development activities and IND-enabling studies.  

Other JAK inhibitors

The decrease in expenses related to other JAK inhibitors primarily resulted from lower expenses in the year ended
December 31, 2020 following the completion of multiple Phase 2 clinical trials of our legacy JAK inhibitors, ATI-501 and
ATI-502, in 2019.

A-101 45% Topical Solution

Expenses  related  to  A-101  45%  Topical  Solution  decreased  primarily  due  to  lower  expenses  in  the  year  ended

December 31, 2020 following the completion of our Phase 3 clinical trials in 2019.

Discovery and other research and development

Research and development expenses related to discovery decreased during the year ended December 31, 2020 as
our discovery-stage assets matured to clinical-stage assets.  As a result of this transition, we focused fewer resources on our
discovery-stage  assets  in  2020  compared  to  2019.    Other  research  and  development  expenses,  which  primarily  included
expenses for medical affairs activities, were lower primarily due to a decrease in activities for our A-101 45% Topical

Table of Contents

Solution,  ATI-501  and  ATI-502  clinical  trials  that  were  completed  in  2019.    Additionally,  travel  expenses  were  lower
during the year ended December 31, 2020 due to the COVID-19 pandemic.

Personnel and stock-based compensation

Personnel expenses and stock-based compensation decreased due to lower headcount primarily resulting from the

restructuring announced in September 2019.  

Milestones and licensing and contingent consideration

In 2019, we recorded $5.5 million of expenses for payments under a license agreement upon the achievement of a
development milestone and a fee related to a contract amendment.  The change in contingent consideration during the year
ended December 31, 2020 was the result of updates to our assumptions as a result of the completion of a successful Phase 1
clinical  trial  for  ATI-450  and  the  submission  and  allowance  of  an  IND  for  ATI-1777,  while  the  change  in  contingent
consideration  during  the  year  ended  December  31,  2019  was  the  result  of  updates  to  our  assumptions  as  a  result  of  the
submission and allowance of an IND for ATI-450.

Personnel and stock-based compensation expenses decreased due to lower headcount primarily resulting from the
restructuring announced in September 2019.  Professional and legal fees included accounting, legal, investor relations and
corporate  communication  costs,  as  well  as  legal  fees  related  to  patents  and  current  lawsuits  described  in  this  report.
 Professional and legal fees were lower year-over-year primarily due to lower corporate legal fees.  Facility and support
services included general office expenses, information technology costs and other expenses, and decreased primarily due to
lower operational and other overhead costs.  Other general and administrative expenses was lower primarily due to reduced
travel-related activities in light of the COVID-19 pandemic.

Goodwill Impairment

During the year ended December 31, 2019, we performed an impairment analysis due to a decline in our stock
price.    Our  impairment  analysis  noted  that  the  fair  value  for  the  therapeutics  reporting  unit  was  less  than  its  carrying
value.  As a result, we recorded an impairment charge of $18.5 million. 

Other Expense, net

The $2.1 million decrease in other expense, net was primarily due to lower interest expense and fees associated

with outstanding debt balances.

Loss from Discontinued Operations

The  decrease  in  loss  from  discontinued  operations  was  due  to  the  divestiture  of  RHOFADE  (see  Note  3  to  the
consolidated  financial  statements  included  in  this  report  for  additional  information).    We  recorded  income  from
discontinued  operations  of  $0.1  million  during  the  year  ended  December  31,  2020  which  consisted  of  $0.4  million  of
RHOFADE  product  sales  due  to  a  reversal  of  previously  accrued  product  sales-related  reserves,  partially  offset  by  $0.3
million of expenses.

The increase in expenses for ATI-450 resulted primarily from preclinical development activities as well as a Phase

1 clinical trial, which was initiated and near completion during the year ended December 31, 2019.

ATI-1777

Expenses  related  to  ATI-1777  increased  during  the  year  ended  December  31,  2019  due  to  higher  preclinical

activities and IND-enabling preclinical studies.

ATI-2138

Expenses  for  ATI-2138  were  higher  during  the  year  ended  December  31,  2019  primarily  due  to  preclinical

development activities.  

Other JAK inhibitors

Development  expenses  related  to  other  JAK  inhibitors  decreased  primarily  due  to  lower  expenses  in  the  year

ended December 31, 2019 following the completion of multiple Phase 2 clinical trials of ATI-501 and ATI-502 in 2019.

A-101 45% Topical Solution

Expenses related to A-101 45% Topical Solution increased primarily due to higher expenses associated with our

two pivotal Phase 3 clinical trials, which were initiated during 2018 and were completed in 2019.

Discovery and other research and development

Discovery  expenses  were  consistent  year-over-year  and  reflected  our  efforts  to  progress  various  programs  to
candidate  selection  and  clinical-stage.    The  decrease  in  other  research  and  development  expenses  was  primarily  due  to
lower costs related to legacy dermatology assets and lower travel expenses.

Personnel and stock-based compensation

The increase in personnel expenses, which includes restructuring expenses, was primarily the result of increased

headcount prior to our restructuring in 2019.  Restructuring expenses primarily included the cost of termination benefits

73

    
Table of Contents

given to employees that were involuntarily terminated during the year ended December 31, 2019.  The decrease in stock-
based compensation expense was primarily the result of forfeitures by certain employees during 2019.

Milestones and licensing and contingent consideration

In 2019, we recorded $5.5 million of expenses for payments under a license agreement upon the achievement of a
development milestone and a fee related to a contract amendment.  The change in contingent consideration during the year
ended December 31, 2019 was the result of updates to our assumptions as a result of the submission and allowance of an
IND  for  ATI-450.    The  change  in  contingent  consideration  during  the  year  ended  December  31,  2018  was  the  result  of
updates  to  our  assumptions  related  to  ATI-1777  that  reflected  the  achievement  of  a  specified  development  milestone  in
November 2018 under the Confluence Agreement.

Personnel expenses, which includes restructuring expenses, and stock-based compensation expenses increased due
to higher headcount prior to our restructuring.  Restructuring expenses primarily include the costs of termination benefits
given to employees that were involuntarily terminated during the year ended December 31, 2019.  Professional and legal
fees  included  accounting,  legal,  investor  relations  and  corporate  communication  costs,  as  well  as  legal  fees  related  to
patents and business development.  The decrease in professional and legal fees was primarily related to lower corporate
communications  costs  as  well  as  lower  legal  costs  incurred  related  to  patents.    Facility  and  support  services  included
general office expenses and information technology costs, which increased due to our new office and laboratory facility in
St.  Louis,  which  we  moved  into  in  2019,  as  well  as  higher  headcount  prior  to  our  restructuring.  Other  general  and
administrative expenses included insurance, travel costs, depreciation and other miscellaneous expenses.

Goodwill Impairment

During the year ended December 31, 2019, we performed an impairment analysis due to a decline in our stock
price.    Our  impairment  analysis  noted  that  the  fair  value  for  the  therapeutics  reporting  unit  was  less  than  its  carrying
value.  As a result, we recorded an impairment charge of $18.5 million.

Other Income (Expense), net

The $5.2 million decrease in other income (expense), net was primarily due to higher interest expense incurred on

outstanding debt balances.

Loss from Discontinued Operations

In  September  2019,  we  announced  the  completion  of  a  strategic  review  and  our  decision  to  refocus  on  our
immuno-inflammatory development programs and to actively seek partners for our commercial products.  The decrease in
loss from discontinued operations was driven by higher product sales, net partially offset by higher expenses (see Note 18
to the consolidated financial statements included in this report for additional information).

Liquidity and Capital Resources

Since  our  inception,  we  have  incurred  net  losses  and  negative  cash  flows  from  our  operations.    Prior  to  our
acquisition of Confluence in August 2017, we did not generate any revenue.  We have financed our operations over the last
several years primarily through sales of our equity securities in public offerings and a private placement transaction, as well
as debt financings.  We may engage in additional debt and equity financing transactions in order to raise additional funds.
 In addition, to the extent we are able to consummate transactions with potential third-party partners to further develop,
obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates,  we  may  receive  upfront  payments,  milestone
payments or royalties from such arrangements that would increase our liquidity.  

As of December 31, 2020, we had cash, cash equivalents and marketable securities of $54.1 million. Subsequent
to  December  31,  2020,  we  raised  net  proceeds  of  $103.5  million  through  a  public  offering  of  common  stock.  Cash  in
excess  of  immediate  requirements  is  invested  in  accordance  with  our  investment  policy,  primarily  with  a  view  towards
liquidity and capital preservation.  

We  currently  have  no  ongoing  material  financing  commitments,  such  as  lines  of  credit  or  guarantees,  that  are
expected  to  affect  our  liquidity,  other  than  our  term  loan  facility,  lease  obligations,  and  contingent  obligations  under  the
Confluence Agreement, which is summarized above under “Overview—Acquisition and License Agreements.”

Equity Financing

January 2021 Public Offering

In January 2021, we closed a public offering in which we sold 6,306,271 shares of common stock at a price to the
public  of  $17.50  per  share,  for  aggregate  gross  proceeds  of  $110.4  million.  We  paid  underwriting  discounts  and
commissions of $6.6 million, and we also incurred expenses of $0.3 million in connection with the offering.  As a result,
the net offering proceeds received by us, after deducting underwriting discounts, commissions and offering expenses, were
$103.5 million.

Equity Purchase Agreement with Lincoln Park Capital Fund, LLC  

In  August  2020,  we  entered  into  a  purchase  agreement,  or  the  Purchase  Agreement,  with  Lincoln  Park.  The
Purchase Agreement provided that, upon the terms and subject to the conditions and limitations set forth therein, we could
sell to Lincoln Park, at our discretion, up to $15.0 million of shares of our common stock over the 36-month term of the
Purchase  Agreement.  Upon  execution  of  the  Purchase  Agreement,  we  issued  121,584  shares  of  our  common  stock  to
Lincoln Park as commitment shares in accordance with the closing conditions contained within the Purchase Agreement.
The  commitment  shares  were  valued  using  the  closing  price  of  our  common  stock  on  the  effective  date  of  the  Purchase
Agreement resulting in an aggregate fair value of $0.3 million.  Through December 31, 2020, we sold 2,111,170 shares of
our common stock to Lincoln Park under the Purchase Agreement for net proceeds of $7.7 million. We did not sell any
additional shares prior to terminating the Purchase Agreement in January 2021 in connection with the public offering of
common stock described above.

October 2018 Public Offering

In October 2018, we closed a public offering in which we sold 9,941,750 shares of common stock at a price to the
public  of  $10.75  per  share,  for  aggregate  gross  proceeds  of  $106.9  million.    We  paid  underwriting  discounts  and
commissions of $6.4 million to the underwriters, and we incurred expenses of $0.3 million in connection with the offering.
 As a result, the net offering proceeds received by us, after deducting underwriting discounts, commissions and offering
expenses, were $100.2 million.  

Debt Financing

Loan and Security Agreement with Silicon Valley Bank

In March 2020, we entered into a Loan and Security Agreement with SVB.  The Loan and Security Agreement
provides  for  $11.0  million  in  term  loans,  of  which  we  borrowed  the  entire  amount  on  March  30,  2020.    The  Loan  and
Security Agreement is secured by substantially all of our assets other than intellectual property.

Table of Contents

The  term  loan  repayment  schedule  provides  for  interest  only  payments  beginning  April  1,  2020  and  continuing
through  March  1,  2022,  followed  by  24  consecutive  equal  monthly  installments  of  principal,  plus  monthly  payments  of
accrued  interest,  starting  on  April  1,  2022  and  continuing  through  the  maturity  date  of  March  1,  2024.  All  outstanding
principal and accrued and unpaid interest will be due and payable on the maturity date.  The Loan and Security Agreement
provides for an annual interest rate equal to the greater of (i) the prime rate then in effect as reported in The Wall Street
Journal plus 2% and (ii) 6.75%.

The  Loan  and  Security  Agreement  includes  a  final  payment  fee  equal  to  5%  of  the  original  principal  amount
borrowed.    We  have  the  option  to  prepay  the  outstanding  balance  of  the  term  loans  in  full,  subject  to  a  prepayment
premium of (i) 3% of the original principal amount borrowed for any prepayment on or prior to the first anniversary of
March 30, 2020, (ii) 2% of the original principal amount borrowed for any prepayment after the first anniversary and on or
before the second anniversary of March 30, 2020 or (iii) 1% of the original principal amount borrowed for any prepayment
after the second anniversary of March 30, 2020 but before March 1, 2024.

The  Loan  and  Security  Agreement  contains  a  customary  covenant  that  limits  our  ability,  subject  to  specified

exceptions, to incur additional indebtedness without the prior written consent of SVB.

Loan and Security Agreement with Oxford Finance LLC

In  October  2018,  we  entered  into  a  Loan  and  Security  Agreement  with  Oxford.    The  Loan  and  Security
Agreement  provided  for  up  to  $65.0  million  in  term  loans,  of  we  borrowed  $30.0  million  in  October  2018.    In  October
2019, we repaid in full the $30.0 million that was outstanding under the Loan and Security Agreement, together with all
accrued and unpaid interest and fees.

2018

During  the  year  ended  December  31,  2020,  operating  activities  used  $38.6  million  of  cash  primarily  resulting
from our net loss of $51.0 million and changes in our operating assets and liabilities of $2.4 million, partially offset by non-
cash adjustments of $14.7 million.  Net cash used by changes in our operating assets and liabilities during the year ended
December 31, 2020 consisted of a $8.9 million decrease in accounts payable and accrued expenses, partially offset by a
$4.9  million  decrease  in  accounts  receivable  and  a  $1.7  million  decrease  in  prepaid  expenses  and  other  assets.    The net
decrease in accounts payable and accrued expenses was primarily driven by lower overall operating expenses as well as
expenses  incurred,  but  not  yet  paid,  as  of  December  31,  2020  compared  to  the  year  ended  December  31,  2019.    The
decrease  in  accounts  receivable  was  primarily  the  result  of  cash  received  from  Allergan  related  to  sales  of  RHOFADE
made during the year ended December 31, 2019.  The decrease in prepaid expenses and other assets was primarily due to
amortization  of  the  premiums  for  our  corporate  insurance  policies,  which  we  expense  equally  over  the  policy  term,
partially  offset  by  prepayment  of  policies  for  2021.    Non-cash  expenses  of  $14.7  million  were  primarily  composed  of
stock-based  compensation  expense  of  $11.2  million,  a  charge  of  $2.4  million  related  to  the  change  in  the  fair  value  of
contingent consideration and depreciation and amortization expense of $1.3 million.  

During  the  year  ended  December  31,  2019,  operating  activities  used  $96.4  million  of  cash  primarily  resulting
from our net loss of $161.4 million and changes in our operating assets and liabilities of $2.7 million, partially offset by
non-cash adjustments of $67.6 million.  Net cash used by changes in our operating assets and liabilities during the year
ended  December  31,  2019  consisted  of  a  $5.1  million  decrease  in  accounts  payable  and  accrued  expenses  and  a  $0.8
million increase in accounts receivable, which were partially offset by a $3.2 million decrease in prepaid expenses and

76

    
    
    
 
 
 
 
Table of Contents

other assets.  The decrease in accounts payable and accrued expenses was primarily driven by lower levels of expenses,
including  sales  discounts  and  allowances,  as  the  result  of  the  disposition  of  RHOFADE,  and  lower  research  and
development  expenses  as  a  result  of  the  completion  of  our  two  pivotal  Phase  3  clinical  trials  for  A-101  45%  Topical
Solution, as well as the timing of vendor invoicing and payments.  The increase in accounts receivable was primarily the
result  of  the  timing  of  cash  receipts  from  our  contract  research  customers.   The  decrease  in  prepaid  expenses  and  other
assets was due to research and development activities primarily related to preclinical development activities for ATI-450
and legacy JAK inhibitors, which concluded during the year ended December 31, 2019, and the elimination of sales and
marketing activities as a result of the disposition of RHOFADE in October 2019.  Non-cash expenses of $67.6 million were
composed of an intangible asset impairment charge of $27.6 million, a goodwill impairment charge of $18.5 million, stock-
based compensation expense of $16.2 million, a charge of $0.7 million related to the change in the fair value of contingent
consideration  and  depreciation  and  amortization  expense  of  $6.4  million,  partially  offset  by  a  gain  of  $1.9  million
recognized on the disposition of RHOFADE.  

During  the  year  ended  December  31,  2018,  operating  activities  used  $100.8  million  of  cash  primarily  resulting
from our net loss of $132.7 million, partially offset by changes in our operating assets and liabilities of $9.4 million, and
non-cash adjustments of $22.5 million.  Net cash provided by changes in our operating assets and liabilities during the year
ended  December  31,  2018  consisted  of  a  $13.8  million  increase  in  accounts  payable  and  accrued  expenses,  which  was
partially offset by a $4.4 million increase in accounts receivable.  The increase in accounts payable and accrued expenses
was  primarily  driven  by  expenses  incurred,  but  not  yet  paid,  as  of  December  31,  2018,  as  well  as  the  timing  of  vendor
invoicing  and  payments.    Expenses  incurred,  but  not  yet  paid,  as  of  December  31,  2018  primarily  included  sales  and
marketing expenses related to the commercial launch of ESKATA in the United States in May 2018, amounts payable for
copay assistance and commercial rebates related to sales of RHOFADE which we began selling in December 2018, as well
as  expenses  related  to  our  Phase  3  clinical  trials  for  A-101  45%  Topical  Solution  and  our  Phase  2  clinical  trials  for  our
legacy JAK inhibitors.  The increase in accounts receivable was the result of the commercial launch of ESKATA in May
2018 and sales of RHOFADE which we acquired in November 2018.  Non-cash expenses of $22.5 million were primarily
composed of stock-based compensation expense.

Investing Activities

During  the  year  ended  December  31,  2020,  investing  activities  provided  $6.4  million  of  cash  consisting  of
proceeds from sales and maturities of marketable securities of $54.6 million, offset by purchases of marketable securities of
$47.7 million and purchases of equipment and leasehold improvements of $0.5 million.

During  the  year  ended  December  31,  2019,  investing  activities  provided  $105.7  million  of  cash  consisting  of
proceeds  from  sales  and  maturities  of  marketable  securities  of  $210.5  million  and  $34.2  million  from  the  disposition  of
RHOFADE, offset by purchases of marketable securities of $137.4 million and purchases of equipment of $1.6 million.

During  the  year  ended  December  31,  2018,  investing  activities  provided  $9.4  million  of  cash  consisting  of
proceeds from sales and maturities of marketable securities of $239.4 million, offset by purchases of marketable securities
of $161.6 million, $67.1 million for the acquisition of RHOFADE, and purchases of equipment of $1.4 million.

Financing Activities

During the year ended December 31, 2020, financing activities provided $18.4 million of cash consisting of $10.9
million of net borrowings pursuant to the Loan and Security Agreement with SVB and $7.7 million of proceeds from the
issuance of common stock in connection with the Purchase Agreement with Lincoln Park, partially offset by $0.1 million
of finance lease payments and $0.2 million of deferred issuance costs.  

During  the  year  ended  December  31,  2019,  financing  activities  used  $30.3  million  of  cash  consisting  of  $30.0
million for the repayment of our term loan with Oxford and $0.5 million related to finance lease payments, offset by $0.2
million of cash received from the exercise of employee stock options.  

During the year ended December 31, 2018, financing activities provided $128.3 million of cash consisting of net
proceeds  of  $100.2  million  received  from  our  public  offering  of  common  stock  in  October  2018,  $29.9  million  of  net
borrowings pursuant to the Loan and Security Agreement with Oxford and $0.6 million of cash received from the exercise
of  employee  stock  options,  offset  by  $1.8  million  paid  to  the  former  Confluence  equity  holders  as  a  result  of  the
achievement of a development milestone and $0.6 million of finance lease payments.

Funding Requirements

We anticipate we will incur net losses in the near term as we continue the clinical development of ATI-450 as a
potential  treatment  for  moderate  to  severe  rheumatoid  arthritis  and  potentially  other  immuno-inflammatory  diseases  and
ATI-1777  as  a  potential  treatment  for  moderate  to  severe  atopic  dermatitis,  continue  the  development  of  our  preclinical
compounds,  and  continue  to  discover  and  develop  additional  drug  candidates.   We  may  not  be  able  to  generate  revenue
from  these  programs  if,  among  other  things,  our  clinical  trials  are  not  successful,  the  FDA  does  not  approve  our  drug
candidates currently in clinical trials when we expect, or at all, or we are not able to identify and consummate transactions
with third-party partners to further develop, obtain marketing approval for and/or commercialize our drug candidates.  

Our  primary  uses  of  capital  are,  and  we  expect  will  continue  in  the  near  term  to  be,  compensation  and  related
expenses,  clinical  costs,  external  research  and  development  services,  laboratory  and  related  supplies,  legal  and  other
regulatory expenses, and administrative and overhead costs.  Our future funding requirements will be heavily determined
by the resources needed to support the development of our drug candidates.  

As  a  publicly  traded  company,  we  incur  and  will  continue  to  incur  significant  legal,  accounting  and  other
expenses.  In addition, the Sarbanes-Oxley Act of 2002, as well as rules adopted by the SEC and the Nasdaq Stock Market
LLC, requires public companies to implement specified corporate governance practices.  

We believe our existing cash, cash equivalents and marketable securities are sufficient to fund our operating and
capital expenditure requirements for a period greater than 12 months from the date of issuance of our consolidated financial
statements that appear in Item 8 of this Annual Report on Form 10-K based on our current operating assumptions.  We will
require  additional  capital  to  complete  the  clinical  development  of  ATI-450  and  ATI-1777,  to  develop  our  preclinical
compounds,  and  to  support  our  discovery  efforts.    Additional  funds  may  not  be  available  on  a  timely  basis,  on
commercially  acceptable  terms,  or  at  all,  and  such  funds,  if  raised,  may  not  be  sufficient  to  enable  us  to  continue  to
implement our long-term business strategy. Our ability to raise additional capital may be adversely impacted by potential
worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the
United  States  and  worldwide  resulting  from  the  ongoing  COVID-19  pandemic.  If  we  are  unable  to  raise  sufficient
additional  capital  or  generate  revenue  from  transactions  with  potential  third-party  partners  for  the  development  and/or
commercialization of our drug candidates, we may need to substantially curtail our planned operations.  

We may raise additional capital through the sale of equity or debt securities. In such an event, our stockholders’
ownership  will  be  diluted,  and  the  terms  of  these  securities  may  include  liquidation  or  other  preferences  that  adversely
affect the rights of a holder of our common stock.

Because  of  the  numerous  risks  and  uncertainties  associated  with  research  and  development  of  pharmaceutical
drugs, we are unable to estimate the exact amount of our working capital requirements. Our funding requirements in the
near term will depend on many factors, including:

● the number and development requirements of the drug candidates that we may pursue;
● the scope, progress, results and costs of preclinical development, laboratory testing and conducting

preclinical and clinical trials for our drug candidates;

● the costs, timing and outcome of regulatory review of our drug candidates;
● the extent to which we in-license or acquire additional drug candidates and technologies;
● the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our

intellectual property rights and defending any intellectual property-related claims;

● the impact on the timing of our preclinical studies, the recruitment, enrollment, conduct and timing of our

clinical trials and our business due to the COVID-19 pandemic;

● our ability to identify and consummate transactions with third-party partners to further develop, obtain

marketing approval for and/or commercialize our drug candidates, and earn revenue from such arrangements;
and

● the revenue earned from our commercial products as a result of licenses to, or partnerships with, third parties.

See “Risk Factors” for additional risks associated with our substantial capital requirements.

Contractual Obligations and Commitments

We  occupy  space  for  our  headquarters  in  Wayne,  Pennsylvania  under  a  sublease  agreement  which  has  a  term
through October 2023.  In December 2020, we entered into a sub-sublease agreement under which we sub-subleased 8,115
square feet.  The sub-sublease term runs concurrent with the original sublease agreement.  We occupy office and laboratory
space in St. Louis, Missouri under a sublease agreement which has a term through June 2029.  

In  March  2020,  we  borrowed  $11.0  million  under  the  Loan  and  Security  Agreement  with  SVB.    Amounts
borrowed under the Loan and Security Agreement are subject to interest only through March 2022, after which we will be
required to make principal and interest payments through the maturity date of March 2024. 

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

Segment Information

We  have  two  reportable  segments,  therapeutics  and  contract  research.    The  therapeutics  segment  is  focused  on
identifying  and  developing  innovative  therapies  to  address  significant  unmet  needs  for  immuno-inflammatory  diseases.
 The contract research segment earns revenue from the provision of laboratory services to clients through Confluence, our
wholly-owned subsidiary.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements,

as defined in the rules and regulations of the SEC.  

Recently Issued Accounting Pronouncements

In November 2018, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or
ASU,  2018-18,  Collaborative  Arrangements  (Topic  808):    Clarifying  the  Interaction  Between  Topic  808  and  Topic  606,
which,  among  other  things,  provides  guidance  on  how  to  assess  whether  certain  collaborative  arrangement  transactions
should  be  accounted  for  under  Topic  606.   We  adopted  this  standard  as  of  January  1,  2020,  the  impact  of  which  on  our
consolidated financial statements was not significant.  

In  August  2018,  the  FASB  issued  ASU  2018-15,  Intangibles—Goodwill  and  Other—Internal-Use  Software
(Subtopic 350-40).  ASU 2018-15 requires a customer in a cloud computing arrangement that is a service contract to follow
the  internal-use  software  guidance  in  Accounting  Standards  Codification,  or  ASC,  350-40  to  determine  which
implementation costs to capitalize as assets or expense as incurred.  We adopted this standard as of January 1, 2020, the
impact of which on our consolidated financial statements was not significant.    

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820).  The FASB developed the
amendments to ASC 820 as part of its broader disclosure framework project, which aims to improve the effectiveness of
disclosures in the notes to financial statements by focusing on requirements that clearly communicate the most important
information  to  users  of  the  financial  statements.    This  update  eliminates  certain  disclosure  requirements  for  fair  value
measurements for all entities, requires public entities to disclose certain new information and modifies some of the existing
disclosure requirements.  We adopted this standard as of January 1, 2020, the impact of which on our consolidated financial
statements was not significant.  

In  June  2018,  the  FASB,  issued  ASU  2018-07,  Compensation—Stock  Compensation  (Topic  718).    The
amendments  in  this  ASU  expand  the  scope  of  Topic  718  to  include  stock-based  compensation  arrangements  with  non-
employees except for specific guidance on option pricing model inputs and cost attribution.  We adopted this standard as of
January 1, 2019, the impact of which on our consolidated financial statements was not significant.

79

Table of Contents

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).  In July 2018, the FASB issued ASU 2018-
10, Codification Improvements to Topic 842, Leases, and ASU 2018-11, Targeted Improvements, both of which included a
number  of  technical  corrections  and  improvements,  including  additional  options  for  transition.    The  new  standard
establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet
for  all  leases  with  terms  longer  than  12  months.    Leases  are  classified  as  either  finance  or  operating,  with  classification
affecting the pattern of expense recognition in the income statement.  The amendments in ASU 2016-02 must be applied to
all leases existing at the date a company initially applies the standard.  

We adopted the new standard as of January 1, 2019, using the effective date as the date of initial application, and
we  used  the  modified  retrospective  approach.    In  addition,  we  elected  the  practical  expedients  permitted  under  the
transition guidance within the new standard, which, among other things, allowed us to carry forward the historical lease
identification and classification.  We also elected the practical expedient to not separate lease and non-lease components, as
well as the short-term lease exemption which allowed us to not capitalize leases with terms less than 12 months that do not
contain a reasonably certain purchase option.  Our consolidated financial statements have not been updated, and disclosures
required by the new standard have not been provided, for periods before January 1, 2019.  

The adoption of ASU 2016-02 resulted in us recording additional assets and liabilities of $2.1 million and $2.3
million, respectively, upon adoption on January 1, 2019.  The adoption of ASU 2016-02 did not have a material impact on
our consolidated statement of operations or cash flows.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Our  cash  equivalents  and  marketable  securities  consist  of  money  market  funds,  asset-backed  securities,
commercial paper, corporate debt securities and government agency debt. Our primary exposure to market risk is interest
rate  sensitivity,  which  is  affected  by  changes  in  the  general  level  of  U.S.  interest  rates.    Our  marketable  securities  are
subject to interest rate risk and will fall in value if market interest rates increase.  However, due to the short-term nature and
low-risk profile of our investment portfolio, we do not expect that an immediate 10% change in market interest rates would
have  a  material  effect  on  the  fair  market  value  of  our  investment  portfolio.   We  have  the  ability  to  hold  our  marketable
securities  until  maturity,  and  therefore  we  would  not  expect  our  operating  results  or  cash  flows  to  be  affected  to  any
significant degree by the effect of a change in market interest rates on our investments.

The  Loan  and  Security  Agreement  with  SVB  provides  for  an  annual  interest  rate  equal  to  the  greater  of  (i)  the
prime rate then in effect as reported in The Wall Street Journal plus 2% and (ii) 6.75%.  To the extent that any present or
future credit facilities that we enter into are based on a floating interest rate, we will be subject to risks relating to changes
in market interest rates.  In periods of rising interest rates when we have such debt outstanding, our interest expense would
increase.  Based upon our debt outstanding of $11.0 million as of December 31, 2020, a 100 basis-point increase in the
interest rate on our loan with SVB would result in $0.1 million of additional interest expense on an annualized basis.

The uncertainty that exists with respect to the economic impact of the global COVID-19 pandemic has introduced

significant volatility in the financial markets during and subsequent to the year ended December 31, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Aclaris Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Aclaris Therapeutics, Inc. and its subsidiaries
(the  “Company”)  as  of  December  31,  2020  and  2019,  and  the  related  consolidated  statements  of  operations  and
comprehensive loss, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31,
2020, including the related notes (collectively referred to as the “consolidated financial statements”).  In our opinion, the
consolidated  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  as  of
December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period
ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America.  

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility
is  to  express  an  opinion  on  the  Company’s  consolidated  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  of  these  consolidated  financial  statements  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
consolidated  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  consolidated
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  consolidated  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 consolidated financial statements. We believe that our
audits provide a reasonable basis for our opinion.  

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated
financial  statements  that  was  communicated  or  required  to  be  communicated  to  the  audit  committee  and  that  (i)  relates  to
accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging,
subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the
consolidated  financial  statements,  taken  as  a  whole,  and  we  are  not,  by  communicating  the  critical  audit  matter  below,
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Fair Value of Contingent Consideration Liability

As  described  in  Notes  2  and  4  to  the  consolidated  financial  statements,  the  Company  initially  recorded  a
contingent consideration liability related to future potential payments resulting from the acquisition of Confluence based
upon  the  achievement  of  certain  development,  regulatory  and  commercial  milestones,  as  well  as  future  projected  sales
performance, at its estimated fair value on the date of acquisition.  Management evaluates fair value estimates of contingent
consideration liabilities on a quarterly basis.  Management estimates the fair value of the contingent consideration liability
associated with sales milestones and royalties by estimating future sales levels, assigning an achievement probability and

82

Table of Contents

discounting the associated cash payment to its present value using a risk-adjusted rate of return.  Management estimates the
fair  value  of  the  contingent  consideration  liability  for  regulatory  milestones  by  assigning  an  achievement  probability  to
each potential milestone and discounting the associated cash payments to their present values using a credit-risk-adjusted
interest rate. Changes in the fair value of the contingent consideration are recorded as income or expense in the Company’s
consolidated  statement  of  operations  and  comprehensive  loss.    Significant  assumptions  used  in  management’s  estimates
include the probability of success of both achieving regulatory milestones and commencing commercialization, which are
based  upon  an  asset’s  current  stage  of  development.    As  of  and  for  the  year  ended  December  31,  2020,  management
recorded a contingent consideration liability of $4.1 million and expense of $2.4 million.

The  principal  considerations  for  our  determination  that  performing  procedures  relating  to  the  fair  value  of  the
contingent consideration liability is a critical audit matter are the significant judgment by management when developing
the  fair  value  estimate,  which  in  turn  led  to  a  high  degree  of  auditor  judgment,  subjectivity  and  effort  in  evaluating  the
significant  assumptions  related  to  the  probability  of  success  of  both  achieving  regulatory  milestones  and  commencing
commercialization. Also, the audit effort involved the use of professionals with specialized skill and knowledge.  

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming
our  overall  opinion  on  the  consolidated  financial  statements.    These  procedures  included,  among  others,  testing
management’s  process  for  developing  the  fair  value  of  the  contingent  consideration  liability  and  evaluating  the
reasonableness of the valuation model and assumptions related to the probability of success of both achieving regulatory
milestones  and  commencing  commercialization.    Evaluating  management’s  assumptions  related  to  the  probability  of
success  of  both  achieving  regulatory  milestones  and  commencing  commercialization  involved  assessing  whether  the
assumptions  used  by  management  were  reasonable  considering  the  agreements  associated  with  the  transaction  and  the
consistency with industry studies and the stage of product development. Professionals with specialized skill and knowledge
were used to assist in evaluating the appropriateness of management’s valuation model.

ACLARIS THERAPEUTICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Nature of Business

Overview

Aclaris Therapeutics, Inc. was incorporated under the laws of the State of Delaware in 2012.  In July 2015, Aclaris
Therapeutics  International  Limited  (“ATIL”)  was  established  under  the  laws  of  the  United  Kingdom  as  a  wholly-owned
subsidiary of Aclaris Therapeutics, Inc.  In March 2016, Vixen Pharmaceuticals, Inc. (“Vixen”) became a wholly-owned
subsidiary of Aclaris Therapeutics, Inc., and in September 2018, Vixen was dissolved.  In August 2017, Confluence Life
Sciences, Inc. (now known as Aclaris Life Sciences, Inc.) (“Confluence”) was acquired by Aclaris Therapeutics, Inc. and
became  a  wholly-owned  subsidiary  thereof.    Aclaris  Therapeutics,  Inc.,  ATIL,  Vixen  and  Confluence  are  referred  to
collectively as the “Company.”  The Company is a clinical-stage biopharmaceutical company focused on developing novel
drug candidates for immuno-inflammatory diseases.  In addition to developing its novel drug candidates, the Company is
pursuing  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop, obtain marketing approval for and/or commercialize its novel drug candidates.  

Liquidity

The  Company’s  consolidated  financial  statements  have  been  prepared  on  the  basis  of  continuity  of  operations,
realization  of  assets  and  the  satisfaction  of  liabilities  in  the  ordinary  course  of  business.   As  of  December  31,  2020,  the
Company  had  cash,  cash  equivalents  and  marketable  securities  of  $54.1  million  and  an  accumulated  deficit  of  $504.5
million. Since inception, the Company has incurred net losses and negative cash flows from its operations.  Prior to the
acquisition  of  Confluence  in  August  2017,  the  Company  had  never  generated  revenue.   There  can  be  no  assurance  that
profitable  operations  will  ever  be  achieved,  and,  if  achieved,  will  be  sustained  on  a  continuing  basis.    In  addition,
development activities, including clinical and preclinical testing of the Company’s drug candidates, will require significant
additional  financing.    The  future  viability  of  the  Company  is  dependent  on  its  ability  to  successfully  develop  its  drug
candidates  and  to  generate  revenue  from  identifying  and  consummating  transactions  with  third-party  partners  to  further
develop, obtain marketing approval for and/or commercialize its development assets or to raise additional capital to finance
its  operations.    The  Company  will  require  additional  capital  to  complete  the  clinical  development  of  ATI-450  and  ATI-
1777, to develop its preclinical compounds, and to support its discovery efforts.  

The Company has taken a number of actions to support its operations and meet its liquidity needs.  In September
2019, the Company announced the completion of a strategic review and its decision to refocus its resources on its immuno-
inflammatory development programs and to actively seek partners for its drug candidates and commercial products.  As a
result of this decision, the Company restructured its operations and reduced its workforce, which lowered operating costs.
  In  October  2019,  the  Company  sold  the  worldwide  rights  to  RHOFADE  (oxymetazoline  hydrochloride)  cream,  1%
(“RHOFADE”)  to  further  its  focus  on  its  development  programs  and  improve  cash  flow.    In  March  2020,  the  Company
borrowed $11.0 million under a term loan facility with Silicon Valley Bank. In August 2020, the Company entered into an
equity  purchase  agreement  (the  “Purchase  Agreement”)  with  Lincoln  Park  Capital  Fund,  LLC  (“Lincoln  Park”).    As  of
December  31,  2020,  the  Company  had  sold  2,111,170  shares  of  common  stock  to  Lincoln  Park  under  the  Purchase
Agreement  for  net  proceeds  of  $7.7  million.    The  Company  did  not  sell  any  additional  shares  prior  to  terminating  the
Purchase  Agreement  in  January  2021  in  connection  with  a  public  offering  of  common  stock  in  which  it  sold  6,306,271
shares of its common stock for net proceeds of $103.5 million.

The Company’s plans to further address its liquidity needs primarily include its ability to control the timing and
spending on its research and development programs.  The Company may also consider other plans to fund its operations
including:  (1)  raising  additional  capital  through  debt  or  equity  financings;  (2)  identifying  third-party  partners  to  further
develop,  obtain  marketing  approval  for  and/or  commercialize  its  drug  candidates,  which  may  generate  revenue  and/or
milestone  payments;  (3)  reducing  spending  on  one  or  more  research  and  development  programs  by  delaying  or
discontinuing development; and/or (4) further restructuring its operations to change its overhead structure.

Additional funds may not be available on a timely basis, on commercially acceptable terms, or at all, and such

funds, if raised, may not be sufficient to enable the Company to continue to implement its long-term business strategy.  

88

Table of Contents

The  Company’s  ability  to  raise  additional  capital  may  be  adversely  impacted  by  potential  worsening  global  economic
conditions  and  the  recent  disruptions  to,  and  volatility  in,  the  credit  and  financial  markets  in  the  United  States  and
worldwide resulting from the ongoing COVID-19 pandemic.  If the Company is unable to raise sufficient additional capital
or generate revenue from transactions with potential third-party partners for the development and/or commercialization of
its drug candidates, it may need to substantially curtail planned operations. The Company’s failure to raise capital as and
when needed could have a negative impact on its financial condition and ability to pursue its business strategies.  

In accordance with Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s
Ability  to  Continue  as  a  Going  Concern  (Subtopic  205-40),  the  Company  evaluated  whether  there  are  conditions  and
events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern
within one year after the date that its consolidated financial statements are issued.  As of the report date, the Company does
not believe that substantial doubt exists about its ability to continue as a going concern.  The Company believes its existing
cash, cash equivalents and marketable securities are sufficient to fund its operating and capital expenditure requirements
for a period greater than 12 months from the date of issuance of these consolidated financial statements.  

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with generally accepted
accounting principles in the United States (“GAAP”).  The consolidated financial statements of the Company include the
accounts  of  the  operating  parent  company,  Aclaris  Therapeutics,  Inc.,  and  its  wholly-owned  subsidiaries,  Confluence,
ATIL,  and  Vixen  (for  periods  prior  to  its  dissolution  in  2018).    All  significant  intercompany  transactions  have  been
eliminated.    Based  upon  the  Company’s  revenue,  the  Company  believes  that  gross  profit  does  not  provide  a  meaningful
measure  of  profitability  and,  therefore,  has  not  included  a  line  item  for  gross  profit  on  the  consolidated  statement  of
operations.  

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year financial statement presentation.

Discontinued Operations

In September 2019, the Company announced the completion of a strategic review and its decision to refocus its
resources on its immuno-inflammatory development programs and to actively seek partners for its commercial products.
 The Company also announced a plan to terminate 86 employees (see Note 17).  

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  management  to  make  estimates  and
assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the
date of the financial statements and the reported amounts of expenses during the reporting periods.  Significant estimates
and assumptions reflected in these financial statements include, but are not limited to, research and development expenses,
contingent consideration and the valuation of stock-based awards.  Estimates are periodically reviewed in light of changes
in circumstances, facts and experience.  The COVID-19 pandemic has resulted in a global slowdown in economic activity.
 As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance
that  would  require  an  update  to  its  estimates,  assumptions  and  judgments  or  revise  the  carrying  value  of  its  assets  or
liabilities.  Actual results could differ from the Company’s estimates.

Revenue Recognition

The Company accounts for revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606,
Revenue from Contracts with Customers.  Under ASC Topic 606, revenue is recognized when a customer obtains control
of promised goods or services in an amount that reflects the consideration to which the Company expects to be entitled in
exchange for those goods or services.  

89

Table of Contents

To determine revenue recognition in accordance with ASC Topic 606, the Company performs the following five
steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine
the  transaction  price,  (iv)  allocate  the  transaction  price  to  the  performance  obligations  in  the  contract,  and  (v)  recognize
revenue  when  (or  as)  performance  obligations  are  satisfied.   At  contract  inception,  the  Company  assesses  the  goods  or
services promised within a contract with a customer to identify the performance obligations, and to determine if they are
distinct.  The Company recognizes the revenue that is allocated to each distinct performance obligation when (or as) that
performance  obligation  is  satisfied.    The  Company  only  recognizes  revenue  when  collection  of  the  consideration  it  is
entitled to under a contract with a customer is probable.

Product Sales, net

The Company sold RHOFADE and ESKATA (hydrogen peroxide) topical solution, 40% (w/w) (“ESKATA”), its
non-marketed product approved by the U.S. Food and Drug Administration, during the years ended December 31, 2019
and  2018  to  a  limited  number  of  wholesalers  in  the  United  States  (collectively,  its  “Customers”).    These  Customers
subsequently  resold  the  Company’s  products  to  pharmacies  and  health  care  providers.    In  addition  to  distribution
agreements with Customers, the Company entered into, or was subject to, arrangements with third-party payors, including
pharmacy  benefit  managers  and  government  agencies,  as  well  as  group  purchasing  organizations  (“GPOs”),  which
provided for government mandated or privately negotiated rebates, chargebacks, and discounts with respect to the purchase
of the Company’s commercial products.  The Company discontinued selling ESKATA in August 2019.  The Company sold
the  worldwide  rights  to  RHOFADE  in  October  2019  (see  Note  3).    Product  sales,  net  is  presented  in  discontinued
operations for all periods presented.  

The Company recognized revenue from product sales at the point the Customer obtained control of the product,
which  generally  occurred  upon  delivery.    The  Company  also  included  estimates  of  variable  consideration  in  the  same
period  revenue  was  recognized.    Components  of  variable  consideration  include  trade  discounts  and  allowances,  product
returns,  government  rebates,  discounts  and  rebates,  other  incentives  such  as  patient  co-pay  assistance,  and  other  fee  for
service amounts.  Variable consideration was recorded on the consolidated balance sheet as either a reduction of accounts
receivable,  if  payable  to  a  Customer,  or  as  a  current  liability,  if  payable  to  a  third  party  other  than  a  Customer.    The
Company  considered  all  relevant  information  when  estimating  variable  consideration  such  as  contractual  and  statutory
requirements,  specific  known  market  events  and  trends,  industry  data  and  forecasted  customer  buying  and  payment
patterns.  The amount of net revenue that can be recognized is constrained by estimates of variable consideration which are
included in the transaction price.  Payment terms with Customers did not exceed one year and, therefore, the Company did
not  account  for  a  financing  component  in  its  arrangements.    The  Company  expensed  incremental  costs  of  obtaining  a
contract with a Customer, including sales commissions, when incurred as the period of benefit was less than one year.  

Trade Discounts and Allowances - The Company provided Customers with trade discounts, rebates, allowances
and/or other incentives.  The Company recorded estimates for these items as a reduction of revenue in the same period the
revenue was recognized.  

Government  and  Payor  Rebates  -  The  Company  contracted  with,  or  was  subject  to  arrangements  with,  certain
third-party payors, including pharmacy benefit managers and government agencies, for the payment of rebates with respect
to  utilization  of  its  commercial  products.    The  Company  also  entered  into  agreements  with  GPOs  that  provided  for
administrative fees and discounted pricing in the form of volume-based rebates.  The Company was also subject to discount
and rebate obligations under state Medicaid programs and Medicare.  The Company recorded estimates for these discounts
and rebates as a reduction of revenue in the same period the revenue was recognized.  

Other Incentives - The Company maintained a co-pay assistance program which was intended to provide financial
assistance to qualified commercially-insured patients with prescription drug co-payments required by third-party payors.
 The Company estimated and recorded accruals for these incentives as a reduction of revenue in the period the revenue was
recognized.      The  Company  estimated  amounts  for  co-pay  assistance  based  upon  the  number  of  claims  and  the  cost  per
claim that the Company expected to receive associated with product that had been sold to Customers but remained in the
distribution channel at the end of each reporting period.  

Product Returns - Consistent with industry practice, the Company has a product returns policy for RHOFADE that
provides  Customers  a  right  of  return  for  product  purchased  within  a  specified  period  prior  to  and  subsequent  to  the
product’s expiration date. The right of return lapses upon shipment of the product to a patient.  The Company recorded an
estimate for the amount of its products which may be returned as a reduction of revenue in the period the related revenue

90

Table of Contents

was  recognized.  The  Company’s  estimate  for  product  returns  was  based  upon  available  industry  data  and  its  own  sales
information,  including  its  visibility  into  the  inventory  remaining  in  the  distribution  channel.   There  is  no  return  liability
associated with sales of ESKATA as the Company had a no returns policy for ESKATA when it was commercialized.

Contract Research

The  Company  earns  contract  research  revenue  from  the  provision  of  laboratory  services  to  clients  through
Confluence, its wholly-owned subsidiary.  Contract research revenue is generally evidenced by contracts with clients which
are on an agreed upon fixed-price, fee-for-service basis and are generally billed on a monthly basis in arrears for services
rendered.  Revenue related to these contracts is generally recognized as the laboratory services are performed, based upon
the rates specified in the contracts.  Under ASC Topic 606, the Company elected to apply the “right to invoice” practical
expedient when recognizing contract research revenue and as such, recognizes revenue in the amount which it has the right
to invoice.  ASC Topic 606 also provides an optional exemption, which the Company has elected to apply, from disclosing
remaining  performance  obligations  when  revenue  is  recognized  from  the  satisfaction  of  the  performance  obligation  in
accordance with the “right to invoice” practical expedient.

The Company also received revenue from grants under the Small Business Innovation Research program of the
National Institutes of Health, or NIH.  During the year ended December 31, 2018, the Company had two active grants from
NIH related to early-stage research.  There are no remaining funds available under the grants.

Other Revenue

Licenses of Intellectual Property – The Company recognizes revenue received from non-refundable, upfront fees
related to the licensing of intellectual property when the intellectual property is determined to be distinct from the other
performance obligations identified in the arrangement, the license has been transferred to the customer, and the customer is
able to use and benefit from the license.  

Milestone  Payments  –  At  the  inception  of  each  arrangement  that  includes  milestone  payments,  the  Company
evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the
transaction price using the most likely amount method.  If it is probable that a significant revenue reversal would not occur,
the  associated  milestone  value  is  included  in  the  amount  allocated  to  the  license  of  intellectual  property.    Milestone
payments  that  are  not  within  the  control  of  the  Company  or  the  counterparty,  such  as  regulatory  approvals,  are  not
considered probable of being achieved until those approvals are received.

Cash, Cash Equivalents and Restricted Cash

The Company considers all short-term, highly liquid investments with original maturities of three months or less
at  acquisition  date  to  be  cash  equivalents.    Cash  equivalents,  which  have  consisted  of  money  market  accounts  and
commercial paper, are stated at fair value.  Total cash, cash equivalents and restricted cash as shown in the consolidated
statements of cash flows as of December 31, 2020 and 2019 includes $0 and $1.8 million, respectively, of restricted cash,
consisting of funds in escrow pursuant to the asset purchase agreement with EPI Health, LLC (“EPI Health”) (see Note
15).

Marketable Securities

Marketable securities with original maturities of greater than three months and remaining maturities of less than
one year from the balance sheet date are classified as short-term. Marketable securities with remaining maturities of greater
than one year from the balance sheet date are classified as long-term.

The Company classifies all of its marketable securities as available-for-sale securities. The Company’s marketable
securities  are  measured  and  reported  at  fair  value  using  either  quoted  prices  in  active  markets  for  identical  securities  or
quoted prices in markets that are not active for identical or similar securities. Unrealized gains and losses are reported as a
separate component of stockholders’ equity. The cost of securities sold is determined on a specific identification basis, and
realized  gains  and  losses,  if  any,  are  included  in  other  income  (expense),  net  within  the  consolidated  statement  of
operations  and  comprehensive  loss.  If  any  adjustment  to  fair  value  reflects  a  decline  in  the  value  of  the  investment,  the
Company considers available evidence to evaluate the extent to which the decline is “other than

91

Table of Contents

temporary”  and  reduces  the  investment  to  fair  value  through  a  charge  to  the  statement  of  operations  and  comprehensive
loss.  

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is recognized using
the  straight-line  method  over  the  useful  life  of  the  asset.  Computer  equipment  is  depreciated  over  three  years.
Manufacturing  and  laboratory  equipment  is  depreciated  over  five  years.  Furniture  and  fixtures  are  depreciated  over  five
years.  Leasehold improvements are depreciated over the shorter of the lease term or their useful life.  Expenditures for
repairs  and  maintenance  of  assets  are  charged  to  expense  as  incurred.  Upon  retirement  or  sale,  the  cost  and  related
accumulated depreciation of assets disposed of are removed from the accounts and any resulting gain or loss is included in
loss from continuing operations.  

Impairment of Long-Lived Assets

Long-lived  assets  consist  of  property  and  equipment.  Long-lived  assets  to  be  held  and  used  are  tested  for
recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may
not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include
significant underperformance of the business in relation to expectations, significant negative industry or economic trends
and  significant  changes  or  planned  changes  in  the  use  of  the  assets.  If  an  impairment  review  is  performed  to  evaluate  a
long-lived asset for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the
use and eventual disposition of the long-lived asset to its carrying value. An impairment loss would be recognized when
estimated undiscounted future cash flows expected to result from the use of an asset are less than its carrying amount. The
impairment loss would be based on the excess of the carrying value of the impaired asset over its fair value, determined
based on discounted cash flows.

Intangible Assets

Intangible assets include both definite-lived and indefinite-lived assets.  Definite-lived intangible assets consist of
a  drug  discovery  platform  the  Company  acquired  through  the  acquisition  of  Confluence,  and  prior  to  the  disposition  in
2019, also included the intellectual property rights related to RHOFADE.  Definite-lived intangible assets are amortized
over their estimated useful life based on the pattern over which the intangible assets are consumed or otherwise used up.  If
that  pattern  cannot  be  reliably  determined,  the  straight-line  method  of  amortization  is  used.    Indefinite-lived  intangible
assets consist of an in-process research and development (“IPR&D”) drug candidate acquired through the acquisition of
Confluence.  IPR&D assets are considered indefinite-lived until the completion or abandonment of the associated research
and  development  efforts.    The  cost  of  IPR&D  is  either  amortized  over  its  estimated  useful  life  beginning  when  the
underlying drug candidate is approved and launched commercially, or expensed immediately if development of the drug
candidate is abandoned or otherwise impaired.

Definite-lived intangible assets are tested for impairment when events or changes in circumstances indicate that
the carrying value of the asset may not be recoverable.  Indefinite-lived intangible assets are tested for impairment at least
annually, which the Company performs during the fourth quarter, or when indicators of an impairment are present.  The
Company recognizes impairment losses when and to the extent that the estimated fair value of an intangible asset is less
than its carrying value.  

During  the  year  ended  December  31,  2019,  the  Company  performed  an  impairment  analysis  of  the  RHOFADE
intangible asset due to its decision to discontinue commercial operations and actively seek a commercialization partner for
RHOFADE.  The Company’s impairment analysis, which primarily utilized a market-participant’s indication of fair value,
resulted in a fair value for the RHOFADE intangible asset which was less than its carrying value.  As a result, the Company
recorded  an  impairment  charge  of  $27.6  million,  which  is  included  in  discontinued  operations  on  the  consolidated
statement of operations, to adjust the carrying value of the RHOFADE intangible asset to its net realizable value (see Note
3).

During the years ended December 31, 2020 and 2019, the Company did not record an IPR&D impairment.

92

Table of Contents

Goodwill

Goodwill is not amortized, but rather is subject to testing for impairment at least annually, which the Company
performs either during the fourth quarter or when indicators of an impairment are present.  The Company considers each of
its  operating  segments,  therapeutics  and  contract  research,  to  be  a  reporting  unit  since  this  is  the  lowest  level  for  which
discrete  financial  information  is  available.    The  impairment  test  performed  by  the  Company  is  a  qualitative  assessment
based  upon  the  then  current  facts  and  circumstances  related  to  operations  of  the  reporting  unit.    If  the  qualitative
assessment indicates an impairment may be present, the Company would perform the required quantitative analysis and an
impairment  charge  would  be  recognized  to  the  extent  that  the  estimated  fair  value  of  the  reporting  unit  is  less  than  its
carrying amount.  However, any loss recognized would not exceed the total amount of goodwill allocated to that reporting
unit.  

During the year ended December 31, 2019, the Company performed an impairment analysis due to a decline in its
stock  price,  which  was  considered  a  triggering  event  to  evaluate  goodwill  for  impairment.   The  Company’s  impairment
analysis,  using  a  market  approach,  noted  that  its  stock  price,  including  a  reasonable  control  premium,  resulted  in  a  fair
value  for  the  therapeutics  reporting  unit  which  was  less  than  its  carrying  value.   As  a  result,  the  Company  recorded  an
impairment charge of $18.5 million.

Leases

Leases represent a company’s right to use an underlying asset and a corresponding obligation to make payments to
a  lessor  for  the  right  to  use  those  assets.    The  Company  evaluates  leases  at  their  inception  to  determine  if  they  are  an
operating lease or a finance lease.  A lease is accounted for as a finance lease if it meets one of the following five criteria:
the lease has a purchase option that is reasonably certain of being exercised, the present value of the future cash flows are
substantially all of the fair market value of the underlying asset, the lease term is for a significant portion of the remaining
economic  life  of  the  underlying  asset,  the  title  to  the  underlying  asset  transfers  at  the  end  of  the  lease  term,  or  if  the
underlying asset is of such a specialized nature that it is expected to have no alternative uses to the lessor at the end of the
term.  Leases that do not meet the finance lease criteria are accounted for as an operating lease.  

The  Company  recognizes  assets  and  liabilities  for  leases  at  their  inception  based  upon  the  present  value  of  all
payments due under the lease.  The Company uses an implicit interest rate to determine the present value of finance leases,
and  its  incremental  borrowing  rate  to  determine  the  present  value  of  operating  leases.    The  Company  determines
incremental  borrowing  rates  by  referencing  collateralized  borrowing  rates  for  debt  instruments  with  terms  similar  to  the
respective lease.  The Company recognizes expense for operating and finance leases on a straight-line basis over the term
of each lease, and interest expense related to finance leases is recognized over the lease term based on the effective interest
method.  The Company includes estimates for any residual value guarantee obligations under its leases in lease liabilities
recorded on its consolidated balance sheet.  

Right-of-use assets are included in other assets and property and equipment, net on the Company’s consolidated
balance sheet for operating and finance leases, respectively.  Obligations for lease payments are included in current portion
of lease liabilities and other liabilities on the Company’s consolidated balance sheet for both operating and finance leases.  

Contingent Consideration

The Company initially recorded a contingent consideration liability related to future potential payments resulting
from  the  acquisition  of  Confluence  based  upon  the  achievement  of  certain  development,  regulatory  and  commercial
milestones, as well as future projected sales performance, at its estimated fair value on the date of acquisition.  The ultimate
amount of future payments, if any, is based on criteria such as sales performance and the achievement of certain regulatory
and  sales  milestones.    The  Company  estimates  the  fair  value  of  the  contingent  consideration  liability  related  to  the
achievement of regulatory milestones by assigning an achievement probability to each potential milestone and discounting
the associated cash payment to its present value using a credit-risk-adjusted interest rate.  The Company estimates the fair
value  of  the  contingent  consideration  liability  associated  with  sales  milestones  and  royalties  by  estimating  future  sales
levels, assigning an achievement probability and discounting the associated cash payments to their present values using a
risk-adjusted rate of return.  Significant assumptions used in the Company’s estimates include the probability of success of
both achieving regulatory milestones and commencing commercialization, which are based upon an asset’s current stage of
development and ranged between 4% and 15%.  The Company evaluates fair value estimates of contingent consideration
liabilities on a quarterly basis.  Any change in fair value reflects new information about the likelihood of the payment of the
contingent consideration and the passage of time. For example, if the timing of the development of an

93

Table of Contents

acquired drug candidate, or the size of potential commercial opportunities related to an acquired drug candidate, differ from
the Company’s assumptions, then the fair value of contingent consideration would be adjusted accordingly. Future changes
in  the  fair  value  of  the  contingent  consideration,  if  any,  will  be  recorded  as  income  or  expense  in  the  Company’s
consolidated statement of operations and comprehensive loss.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development expenses include salaries,
stock-based compensation and benefits of employees, fees paid under licensing agreements, fees paid under a third party
assignment agreement and other operational costs related to the Company’s research and development activities, including
depreciation  expenses  and  the  cost  of  research  and  development  contracts  which  the  Company  has  entered  into  with
outside  vendors  to  conduct  both  preclinical  studies  and  clinical  trials.    Significant  judgment  and  estimates  are  made  in
determining the amount of research and development costs recognized in each reporting period.  The Company analyzes
the progress of its preclinical studies and clinical trials, completion of milestone events, invoices received and contracted
costs  when  estimating  research  and  development  costs.  Actual  results  could  differ  from  the  Company’s  estimates.  The
Company’s historical estimates for research and development costs have not been materially different from the actual costs.

Stock-Based Compensation

The  Company  measures  the  compensation  expense  of  stock-based  awards  granted  to  employees  and  directors
using  the  grant  date  fair  value  of  the  award.    The  Company  has  issued  stock  options  and  restricted  stock  unit  (“RSU”)
awards with service-based vesting conditions, as well as with performance-based vesting conditions.  The Company has
not issued awards that include market-based conditions.  For service-based awards the Company recognizes stock-based
compensation  expense  on  a  straight-line  basis  over  the  requisite  service  period.    For  performance-based  awards  the
Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period beginning
in the period that it becomes probable the performance conditions will occur.  At each balance sheet date, the Company
evaluates  whether  any  performance  conditions  related  to  a  performance-based  award  have  changed.    The  effect  of  any
change  in  performance  conditions  would  be  recognized  as  a  cumulative  catch-up  adjustment  in  the  period  such  change
occurs,  and  any  remaining  unrecognized  compensation  expense  would  be  recognized  on  a  straight-line  basis  over  the
remaining requisite service period.  The impact of forfeitures is recognized in the period in which they occur.  

The Company measures the compensation expense of stock-based awards granted to consultants using the grant
date fair value of the award.  The Company recognizes compensation expense over the period during which services are
rendered by the consultant.

The Company classifies stock-based compensation expense in its statement of operations and comprehensive loss
in  the  same  manner  in  which  the  award  recipient’s  payroll  costs  are  classified  or  in  which  the  award  recipients’  service
payments are classified.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing
model. The Company estimates its expected stock volatility based on the historical volatility of a set of peer companies,
which are publicly traded, and expects to continue to do so until it has adequate historical data regarding the volatility of its
own  publicly-traded  stock  price.  The  expected  term  of  the  Company’s  stock  options  has  been  determined  using  the
“simplified” method for awards that qualify as “plain vanilla” options. The expected term of stock options granted to non-
employees is equal to the contractual term of the option award. The risk-free interest rate is determined by reference to the
U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected
term of the award. The Company uses an expected dividend yield of zero based on the fact that the Company has never
paid cash dividends and does not expect to pay cash dividends in the future.

The fair value of each RSU is measured using the closing price of the Company’s common stock on the date of

grant.

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.

Table of Contents

Foreign Currency Translation

The  reporting  currency  of  the  Company  is  the  U.S.  Dollar.  The  functional  currency  of  ATIL,  the  Company’s
wholly-owned  subsidiary,  is  the  British  Pound.   Assets  and  liabilities  of  ATIL  are  translated  into  U.S.  Dollars  based  on
exchange rates at the end of each reporting period.  Revenues and expenses are translated at average exchange rates during
the reporting period.  Gains and losses arising from the translation of assets and liabilities are included as a component of
accumulated other comprehensive loss within the Company’s consolidated balance sheet.  Gains and losses resulting from
foreign currency transactions are reflected within the Company’s consolidated statement of operations.  The Company has
not utilized foreign currency hedging strategies to mitigate the effect of its foreign currency exposure.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of
deferred  tax  assets  and  liabilities  for  the  expected  future  tax  consequences  of  events  that  have  been  recognized  in  the
financial statements or in the Company’s tax returns.  Deferred taxes are determined based on the difference between the
financial  statement  and  tax  basis  of  assets  and  liabilities  using  enacted  tax  rates  in  effect  in  the  years  in  which  the
differences are expected to reverse.  Changes in deferred tax assets and liabilities are recorded in the provision for income
taxes.  The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and,
to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of
the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense.
Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering
prudent and feasible tax planning strategies.

The  Company  accounts  for  uncertainty  in  income  taxes  recognized  in  the  consolidated  financial  statements  by
applying  a  two-step  process  to  determine  the  amount  of  tax  benefit  to  be  recognized.    First,  the  tax  position  must  be
evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax
position is deemed more likely than not to be sustained, the tax position is then assessed to determine the amount of benefit
to  recognize  in  the  consolidated  financial  statements.    The  amount  of  the  benefit  that  may  be  recognized  is  the  largest
amount that has a greater than 50% likelihood of being realized upon ultimate settlement.  The provision for income taxes
includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as
the related net interest and penalties.

Comprehensive Loss

Comprehensive loss includes net loss as well as other changes in stockholders’ equity that result from transactions
and economic events other than those with stockholders.  Comprehensive loss is comprised of net loss, foreign currency
translation adjustments and unrealized gains (losses) on marketable securities.

Net Loss per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the
period.    Diluted  net  loss  per  share  is  computed  using  the  sum  of  the  weighted  average  number  of  common  shares
outstanding during the period, plus the weighted average number of potential shares of common stock from the assumed
exercise of stock options and warrants and the assumed vesting of RSUs, if dilutive.  Since the Company was in a net loss
position, basic and diluted net loss per share was the same for each of the periods presented.

Fair Value Measurements

Certain assets and liabilities are carried at fair value under GAAP.  Fair value is defined as the exchange price that
would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or
liability  in  an  orderly  transaction  between  market  participants  on  the  measurement  date.  Valuation  techniques  used  to
measure  fair  value  must  maximize  the  use  of  observable  inputs  and  minimize  the  use  of  unobservable  inputs.  Financial
assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair
value hierarchy, of which the first two are considered observable and the last is considered unobservable:

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

95

Table of Contents

● Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for
similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or
liabilities, or other inputs that are observable or can be corroborated by observable market data.

● Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to
determining the fair value of the assets or liabilities, including pricing models, discounted cash flow
methodologies and similar techniques.

The  Company’s  cash  equivalents,  marketable  securities  and  contingent  consideration  are  carried  at  fair  value,
determined according to the fair value hierarchy described above.  The carrying value of the Company’s accounts payable
and  accrued  expenses  approximate  fair  value  due  to  the  short-term  nature  of  these  liabilities.   The  carrying  value  of  the
Company’s  debt  approximates  fair  value  due  to  the  debt  bearing  a  variable  interest  rate  which  is  reflective  of  current
market rates.

Concentration of Credit Risk and of Significant Suppliers

Financial  instruments  that  potentially  expose  the  Company  to  concentrations  of  credit  risk  consist  primarily  of
cash, cash equivalents and marketable securities. The Company holds all cash, cash equivalents and marketable securities
balances  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.

The  Company  is  dependent  on  third-party  manufacturers  to  supply  drug  product,  including  all  underlying
components, for its research and development activities, including preclinical and clinical testing.  These activities could be
adversely affected by a significant interruption in the supply of active pharmaceutical ingredients or other components.  

Segment Reporting

Operating  segments  are  components  of  a  company  for  which  separate  financial  information  is  available  and
evaluated regularly by the chief operating decision maker in assessing performance and deciding how to allocate resources.
 The Company has two reportable segments, therapeutics and contract research.  The therapeutics segment is focused on
identifying  and  developing  innovative  therapies  to  address  significant  unmet  needs  for  immuno-inflammatory  diseases.
 The contract research segment earns revenue from the provision of laboratory services to clients through Confluence, the
Company’s wholly-owned subsidiary.  Contract research revenue is generally evidenced by contracts with clients which are
on an agreed upon fixed-price, fee-for-service basis.  The Company does not report balance sheet information by segment
since  it  is  not  reviewed  by  the  chief  operating  decision  maker,  and  all  of  the  Company’s  tangible  assets  are  held  in  the
United States.

Recently Issued Accounting Pronouncements

In  November  2018,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  ASU  2018-18,  Collaborative
Arrangements  (Topic  808):  Clarifying  the  Interaction  Between  Topic  808  and  Topic  606,  which,  among  other  things,
provides guidance on how to assess whether certain collaborative arrangement transactions should be accounted for under
Topic 606.  The Company adopted this standard as of January 1, 2020, the impact of which on its consolidated financial
statements was not significant.  

In  August  2018,  the  FASB  issued  ASU  2018-15,  Intangibles—Goodwill  and  Other—Internal-Use  Software
(Subtopic 350-40).  ASU 2018-15 requires a customer in a cloud computing arrangement that is a service contract to follow
the  internal-use  software  guidance  in  ASC  350-40  to  determine  which  implementation  costs  to  capitalize  as  assets  or
expense as incurred.  The Company adopted this standard as of January 1, 2020, the impact of which on its consolidated
financial statements was not significant.  

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820).  The FASB developed the
amendments to ASC 820 as part of its broader disclosure framework project, which aims to improve the effectiveness of
disclosures in the notes to financial statements by focusing on requirements that clearly communicate the most important
information to users of the financial statements.  This update eliminates certain disclosure requirements for fair value

measurements for all entities, requires public entities to disclose certain new information and modifies some of the existing
disclosure  requirements.    The  Company  adopted  this  standard  as  of  January  1,  2020,  the  impact  of  which  on  its
consolidated financial statements was not significant.  

In  June  2018,  the  FASB  issued  ASU  2018-07,  Compensation—Stock  Compensation  (Topic  718).    The
amendments  in  this  ASU  expand  the  scope  of  Topic  718  to  include  stock-based  compensation  arrangements  with
nonemployees except for specific guidance on option pricing model inputs and cost attribution.  The Company adopted this
standard as of January 1, 2019, the impact of which on its consolidated financial statements was not significant.  

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).  In July 2018, the FASB issued ASU 2018-
10, Codification Improvements to Topic 842, Leases, and 2018-11, Targeted Improvements, which included a number of
technical corrections and improvements, including additional options for transition.  The new standard establishes a right-
of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with
terms longer than 12 months.  Leases are classified as either finance or operating, with classification affecting the pattern of
expense recognition in the income statement.  The amendments in ASU 2016-02 must be applied to all leases existing at
the date a company initially applies the standard.  The Company adopted the new standard as of January 1, 2019, using the
effective  date  as  the  date  of  its  initial  application,  and  used  the  modified  retrospective  approach.   The  adoption  of  ASU
2016-02 resulted in the Company recording additional assets and liabilities of $2.1 million and $2.3 million, respectively,
upon  adoption  on  January  1,  2019.    The  adoption  of  ASU  2016-02  did  not  have  a  material  impact  on  the  Company’s
consolidated statement of operations and comprehensive loss or cash flows.

3. RHOFADE

Disposition - Asset Purchase Agreement with EPI Health, LLC

In October 2019, the Company entered into an asset purchase agreement with EPI Health pursuant to which the
Company  sold  the  worldwide  rights  to  RHOFADE,  which  included  the  assignment  of  certain  licenses  for  related
intellectual property assets (the “Disposition”).  

Pursuant to the asset purchase agreement, EPI Health paid the Company an upfront payment of $35.2 million.  In
addition,  EPI  Health  agreed  to  pay  the  Company  (i)  potential  sales  milestone  payments  of  up  to  $20.0  million  in  the
aggregate upon the achievement of specified levels of net sales of products as defined in the asset purchase agreement, (ii)
a  specified  high  single-digit  royalty  calculated  as  a  percentage  of  net  sales,  on  a  product-by-product  and  country-by-
country  basis,  until  the  date  that  the  patent  rights  related  to  a  particular  product,  such  as  RHOFADE,  have  expired,
provided, that with respect to sales of RHOFADE in any territory outside of the United States,  such royalty shall be paid
until the date that the RHOFADE patent rights in the particular country have expired or, if later, 10 years from the date of
the first commercial sale of RHOFADE in such country and (iii) 25% of any upfront, license, milestone, maintenance or
fixed  payment  received  by  EPI  Health  in  connection  with  any  license  or  sublicense  of  the  assets  transferred  in  the
Disposition  in  any  territory  outside  of  the  United  States,  subject  to  specified  exceptions.    Finally,  EPI  Health  agreed  to
assume the Company’s obligation to pay specified royalties and milestone payments under certain agreements with third
parties.  

Acquisition – Asset Purchase Agreement with Allergan Sales, LLC

In  November  2018,  the  Company  acquired  the  worldwide  rights  to  RHOFADE,  which  included  an  exclusive
license  to  certain  intellectual  property,  from  Allergan  Sales,  LLC  (“Allergan”)  pursuant  to  an  asset  purchase  agreement.
The acquisition of RHOFADE was accounted for as an asset acquisition in accordance with FASB ASC 805-50.

As of December 31, 2020 and 2019, the Company’s cash equivalents included a money market fund, which was
valued based upon Level 1 inputs.  Cash equivalents as of December 31, 2020 also included commercial paper, which was
valued based upon Level 2 inputs.  The Company’s marketable securities as of December 31, 2020 and 2019 included U.S.
government  agency  debt  securities,  commercial  paper  and  asset-backed  debt  securities,  which  were  valued  based  upon
Level 2 inputs.  Marketable securities as of December 31, 2019 also included corporate debt securities, which were valued
based upon Level 2 inputs.  

In  determining  the  fair  value  of  its  Level  2  investments,  the  Company  relied  on  quoted  prices  for  identical
securities in markets that are not active. These quoted prices were obtained by the Company with the assistance of a third-
party pricing service based on available trade, bid and other observable market data for identical securities.  Quarterly, the
Company compares the quoted prices obtained from the third-party pricing service to other available independent pricing
information to validate the reasonableness of the quoted prices provided.  The Company evaluates whether adjustments to
third-party pricing are necessary and, historically, the Company has not made adjustments to quoted prices obtained from
the  third-party  pricing  service.    During  the  years  ended  December  31,  2020  and  2019,  there  were  no  transfers  between
Level 1, Level 2 and Level 3.  

The increase in contingent consideration of $2.4 million during the year ended December 31, 2020 was primarily
due to updates to the Company’s assumptions resulting from the successful completion of a Phase 1 clinical trial for ATI-
450 and the submission and allowance of an Investigational New Drug Application (“IND”) for ATI-1777.  The change in
acquisition-related  contingent  consideration  of  $0.7  million  during  the  year  ended  December  31,  2019  was  the  result  of
updates to the Company’s assumptions as a result of the submission and allowance of an IND for ATI-450.

In  March  2020,  the  Company  entered  into  a  Loan  and  Security  Agreement  with  Silicon  Valley  Bank  (“SVB”).
 The Loan and Security Agreement provides for $11.0 million in term loans, of which the Company borrowed the entire
amount on March 30, 2020.  The Loan and Security Agreement is secured by substantially all of the assets of the Company
other  than  intellectual  property.    In  connection  with  the  Loan  and  Security  Agreement,  the  Company  issued  to  SVB  a
warrant to purchase up to 460,251 shares of common stock (the “Warrant”) (see Note 9).  The proceeds of the Loan and
Security Agreement were allocated to the term loan and Warrant using a relative fair value approach.

The  term  loan  repayment  schedule  provides  for  interest  only  payments  beginning  April  1,  2020  and  continuing
through  March  1,  2022,  followed  by  24  consecutive  equal  monthly  installments  of  principal,  plus  monthly  payments  of
accrued  interest,  starting  on  April  1,  2022  and  continuing  through  the  maturity  date  of  March  1,  2024.  All  outstanding
principal and accrued and unpaid interest will be due and payable on the maturity date.  The Loan and Security Agreement
provides for an annual interest rate equal to the greater of (i) the prime rate then in effect as reported in The Wall Street
Journal plus 2% and (ii) 6.75%.

The  Loan  and  Security  Agreement  includes  a  final  payment  fee  equal  to  5%  of  the  original  principal  amount
borrowed.  The Company has the option to prepay the outstanding balance of the term loans in full, subject to a prepayment
premium of (i) 3% of the original principal amount borrowed for any prepayment on or prior to the first anniversary of
March 30, 2020, (ii) 2% of the original principal amount borrowed for any prepayment after the first anniversary and on or
before the second anniversary of March 30, 2020 or (iii) 1% of the original principal amount borrowed for any prepayment
after the second anniversary of March 30, 2020 but before March 1, 2024.

Loan and Security Agreement – Oxford Finance LLC

In October 2018, the Company entered into a Loan and Security Agreement with Oxford Finance LLC.  The Loan
and Security Agreement provided for up to $65.0 million in term loans, of which the Company borrowed $30.0 million in
October 2018.  In October 2019, the Company repaid in full the $30.0 million that was outstanding under the Loan and
Security Agreement, together with all accrued and unpaid interest and fees.

9. Stockholders’ Equity

Preferred Stock

As of December 31, 2020 and 2019, the Company’s amended and restated certificate of incorporation authorized
the  Company  to  issue  10,000,000  shares  of  undesignated  preferred  stock.    There  were  no  shares  of  preferred  stock
outstanding as of December 31, 2020 and 2019.  

Common Stock

As of December 31, 2020 and 2019, the Company’s amended and restated certificate of incorporation authorized

the Company to issue 100,000,000 shares of $0.00001 par value common stock.  

Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s
stockholders. Common stockholders are entitled to receive dividends, as may be declared by the board of directors, if any,
subject  to  any  preferential  dividend  rights  of  any  series  of  preferred  stock  that  may  be  outstanding.    No  dividends  have
been declared through December 31, 2020.  

October 2018 Public Offering

In  October  2018,  the  Company  entered  into  an  underwriting  agreement  pursuant  to  which  the  Company  issued
and  sold  9,941,750  shares  of  common  stock  under  registration  statements  on  Form  S-3,  including  the  underwriters’  full
exercise of their option to purchase additional shares. The shares of common stock were sold to the public at a price of
$10.75 per share, for gross proceeds of $106.9 million.  The Company paid underwriting discounts and commissions of
$6.4  million  to  the  underwriters  in  connection  with  the  offering.    In  addition,  the  Company  incurred  expenses  of  $0.3
million in connection with the offering.  The net offering proceeds received by the Company, after deducting underwriting
discounts and commissions and offering expenses, were $100.2 million.

Warrants

The Warrant issued to SVB in March 2020 had an initial exercise price of $0.956 per share, subject to adjustment
as provided in the Warrant. The Warrant became immediately exercisable in full upon the funding of the term loan facility.
 The Company assigned a fair value of $0.4 million to the Warrant using a Black-Scholes valuation methodology, and also
concluded that the Warrant was indexed to its own stock and therefore classified the Warrant as an equity instrument.  In
January 2021, SVB net exercised the Warrant in full, and the Company issued to SVB 388,119 shares of common stock.

Equity Purchase Agreement with Lincoln Park Capital Fund, LLC  

In August 2020, the Company entered into the Purchase Agreement with Lincoln Park which provided that, upon
the  terms  and  subject  to  the  conditions  and  limitations  set  forth  therein,  the  Company  may  sell  to  Lincoln  Park,  at  its
discretion, up to $15.0 million of shares of its common stock over the 36-month term of the Purchase Agreement. Upon
execution  of  the  Purchase  Agreement,  the  Company  issued  121,584  shares  of  its  common  stock  to  Lincoln  Park  as
commitment shares in accordance with the closing conditions contained within the Purchase Agreement. The commitment
shares  were  valued  using  the  closing  price  of  the  Company’s  common  stock  on  the  effective  date  of  the  Purchase
Agreement resulting in an aggregate fair value of $0.3 million. Through December 31, 2020, the Company sold 2,111,170
shares of its common stock to Lincoln Park under the Purchase Agreement for net proceeds of $7.7 million.  The Company
terminated the Purchase Agreement in January 2021. The Company did not sell any additional shares prior to terminating
the  Purchase  Agreement  in  January  2021  in  connection  with  the  public  offering  of  common  stock  described  below  (see
Note 21).

10. Stock-Based Awards

2015 Equity Incentive Plan

In September 2015, the Company’s board of directors adopted the 2015 Equity Incentive Plan (the “2015 Plan”),
and  the  Company’s  stockholders  approved  the  2015  Plan.    The  2015  Plan  became  effective  in  connection  with  the
Company’s initial public offering.  Beginning at the time the 2015 Plan became effective, no further grants may be made

101

Table of Contents

under  the  Company’s  2012  Equity  Compensation  Plan,  as  amended  and  restated  (the  “2012  Plan”).    The  2015  Plan
provides  for  the  grant  of  incentive  stock  options,  nonqualified  stock  options,  stock  appreciation  rights,  restricted  stock
awards, RSU awards, performance stock awards, cash-based awards and other stock-based awards. The number of shares
initially  reserved  for  issuance  under  the  2015  Plan  was  1,643,872  shares  of  common  stock.    The  number  of  shares  of
common stock that may be issued under the 2015 Plan will automatically increase on January 1 of each year ending on
January 1, 2025, in an amount equal to the lesser of (i) 4.0% of the shares of the Company’s common stock outstanding on
December 31 of the preceding calendar year or (ii) an amount determined by the Company’s board of directors. The shares
of  common  stock  underlying  any  awards  that  expire,  are  otherwise  terminated,  settled  in  cash  or  repurchased  by  the
Company under the 2015 Plan and the 2012 Plan will be added back to the shares of common stock available for issuance
under the 2015 Plan.  As of December 31, 2020, 2,423,020 shares remained available for grant under the 2015 Plan.  As of
January  1,  2021,  the  number  of  shares  of  common  stock  that  may  be  issued  under  the  2015  Plan  was  automatically
increased by 1,804,372 shares.  

2017 Inducement Plan

In July 2017, the Company’s board of directors adopted the 2017 Inducement Plan (the “2017 Inducement Plan”).
  The  2017  Inducement  Plan  is  a  non-stockholder  approved  stock  plan  adopted  pursuant  to  the  “inducement  exception”
provided  under  Nasdaq  listing  rules.    The  Company  had  443,000  stock  options  and  28,895  RSUs  outstanding  as  of
December 31, 2020 under the 2017 Inducement Plan.  All shares of common stock that were eligible for issuance under the
2017  Inducement  Plan  after  October  1,  2018,  including  any  shares  underlying  any  awards  that  expire  or  are  otherwise
terminated, reacquired to satisfy tax withholding obligations, settled in cash or repurchased by the Company in the future
that would have been eligible for re-issuance under the 2017 Inducement Plan, were retired. 

2012 Equity Compensation Plan

Upon  the  2015  Plan  becoming  effective,  no  further  grants  can  be  made  under  the  2012  Plan.  The  Company
granted  a  total  of  1,140,524  stock  options  under  the  2012  Plan,  of  which  549,561  and  745,735  were  outstanding  as  of
December 31, 2020 and 2019, respectively.  Stock options granted under the 2012 Plan vested over four years and expire
after ten years.  

Stock Option Valuation

The weighted average assumptions the Company used to estimate the fair value of stock options granted during

the years ended December 31, 2020, 2019 and 2018 were as follows:

The  Company’s  potentially  dilutive  securities,  which  included  stock  options,  RSUs  and  warrants,  have  been

As of December 31, 2020, the Company had federal and state net operating loss (“NOL”) carryforwards of $367.6
million and $369.6 million, respectively, which will begin to expire in 2032.  As of December 31, 2020, the Company also
had federal research and development tax credit carryforwards of $8.6 million which will begin to expire in 2032, and state
research and development tax credit carryforwards of $0.1 million which will begin to expire in 2022. The Company also
has $0.2 million of loss carryforwards in the United Kingdom which can be carried forward indefinitely. Utilization of the
NOLs and research and development tax credit carryforwards in the United States may be subject to a substantial annual
limitation  under  Section  382  of  the  Internal  Revenue  Code  of  1986  due  to  ownership  changes  that  may  have  occurred
previously or that could occur in the future. These ownership changes may limit the amount of carryforwards that can be
utilized annually to offset future taxable income.  In general, an ownership change, as defined by Section 382, results from
transactions increasing the ownership of certain stockholders or public groups in the stock of a corporation by more than
50% over a three-year period. The Company has completed an analysis under Section 382 for NOLs generated from July
13, 2012 through July 20, 2020.  Although the Company has experienced Section 382 ownership changes since 2012, the
Company has concluded that it should have sufficient ability to utilize NOLs accumulated during the periods

tested.    The  Company  has  not  yet  determined  if  a  Section  382  ownership  change  has  occurred  after  July  20,  2020.    In
addition,  the  Company  may  experience  ownership  changes  in  the  future  as  a  result  of  subsequent  shifts  in  its  stock
ownership, some of which may be outside of the Company’s control.

The Company has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax
assets.    The  Company  considered  its  history  of  cumulative  net  losses  incurred  since  inception,  its  lack  of  substantial
revenue generated to date, and its forecasted future operating losses and concluded that it is more likely than not that the
Company  will  not  realize  the  benefits  of  its  deferred  tax  assets.    Accordingly,  a  full  valuation  allowance  has  been
established  against  the  deferred  tax  assets  as  of  December  31,  2020  and  2019.    The  Company  evaluates  positive  and
negative evidence of its ability to realize deferred tax assets at each reporting period.  

Changes in the valuation allowance for deferred tax assets during the years ended December 31, 2020, 2019 and
2018  related  primarily  to  the  increases  in  NOLs,  capitalized  start-up  costs,  and  research  and  development  tax  credit
carryforwards and were as follows:

The  Company  files  tax  returns  as  prescribed  by  the  tax  laws  of  the  jurisdictions  in  which  it  operates.    In  the
normal  course  of  business,  the  Company  is  subject  to  examination  by  federal  and  state  jurisdictions,  where  applicable.
There are currently no pending income tax examinations. The Company’s tax years are still open under statute from 2017
to  the  present.   All  open  years  may  be  examined  to  the  extent  that  tax  credit  or  NOLs  are  used  in  future  periods.    The
Company’s policy is to record interest and penalties related to income taxes as part of its income tax provision.

As  a  result  of  the  Company’s  decision  to  actively  seek  partners  for  its  commercial  products,  the  Company
terminated the finance leases for its fleet vehicles and recognized a loss on lease termination of $0.2 million in the year
ended December 31, 2019, which is included in other income, net in the Company’s consolidated statement of operations.

During  the  year  ended  December  31,  2019,  the  Company  performed  an  impairment  analysis  of  the  RHOFADE
intangible asset due to its decision to discontinue commercial operations and actively seek a commercialization partner for
RHOFADE.  The Company’s impairment analysis, which primarily utilized a third-party indication of fair value, resulted
in  a  fair  value  for  the  RHOFADE  intangible  asset  which  was  less  than  its  carrying  value.    As  a  result,  the  Company
recorded an impairment charge of $27.6 million to adjust the carrying value of the RHOFADE intangible asset to its net
realizable value.

19. Segment Information

The  Company  has  two  reportable  segments,  therapeutics  and  contract  research.    The  therapeutics  segment  is
focused on identifying and developing innovative therapies to address significant unmet needs for immuno-inflammatory
diseases.  The  contract  research  segment  earns  revenue  from  the  provision  of  laboratory  services  to  clients  through
Confluence, the Company’s wholly-owned subsidiary.  Contract research revenue is generally evidenced by contracts with
clients  which  are  on  an  agreed  upon  fixed-price,  fee-for-service  basis.    Corporate  and  other  includes  general  and
administrative expenses as well as eliminations of intercompany transactions.  The Company does not report balance sheet
information by segment since it is not reviewed by the chief operating decision maker, and all of the Company’s tangible
assets are held in the United States.

20. Legal Proceedings

Securities Class Action

On July 30, 2019, plaintiff Linda Rosi (“Rosi”) filed a putative class action complaint captioned Rosi v. Aclaris
Therapeutics, Inc., et al. in the U.S. District Court for the Southern District of New York against the Company and certain
of its executive officers.  The complaint alleges that the defendants violated federal securities laws by, among other things,
failing to disclose an alleged likelihood that regulators would scrutinize advertising materials related to ESKATA and find
that  the  materials  minimized  the  risks  or  overstated  the  efficacy  of  the  product.    The  complaint  seeks  unspecified
compensatory  damages  on  behalf  of  Rosi  and  all  other  persons  and  entities  that  purchased  or  otherwise  acquired  the
Company’s securities between May 8, 2018 and June 20, 2019. 

On September 5, 2019, an additional plaintiff, Robert Fulcher (“Fulcher”), filed a substantially identical putative
class action complaint captioned Fulcher v. Aclaris Therapeutics, Inc., et al. in the same court against the same defendants.

On November 6, 2019, the court consolidated the Rosi and Fulcher actions (together, the “Consolidated Securities

Action”) and appointed Fulcher “lead plaintiff” for the putative class. 

On  January  24,  2020,  Fulcher  filed  a  consolidated  amended  complaint  in  the  Consolidated  Securities  Action,
naming two additional executive officers as defendants, extending the putative class period to August 12, 2019, and adding
allegations  concerning,  among  other  things,  alleged  statements  and  omissions  throughout  the  putative  class  period
concerning ESKATA’s risks, tolerability and effectiveness. The defendants filed a motion to dismiss the consolidated

112

Table of Contents

amended  complaint  on  April  17,  2020.  Fulcher  filed  an  opposition  to  the  defendants’  motion  on  June  15,  2020,  and  the
defendants  filed  a  reply  to  such  opposition  on  August  4,  2020.  Oral  argument  on  the  pending  motion  to  dismiss  is
scheduled for February 25, 2021. The motion remains under judicial consideration.

The Company and the other defendants dispute plaintiffs’ claims in the Consolidated Securities Action and intend
to defend the matter vigorously.  At this time, the Company cannot reasonably predict the outcome or potential loss, if any,
that could result from this matter.

Stockholder Derivative Action

On November 15, 2019, plaintiff Keith Allred (“Allred”) filed a derivative stockholder complaint captioned Allred
v. Walker et al. in the U.S. District Court for the Southern District of New York against certain of the Company’s directors
and executive officers.  The complaint alleges that the defendants, among other things, breached their fiduciary duties as
directors and/or officers in connection with the claims alleged in the Consolidated Securities Action.  The complaint seeks,
among other things, unspecified compensatory damages on behalf of the Company.  

On November 25, 2019, an additional plaintiff, Bruce Brown (“Brown”), filed a substantially identical complaint

captioned Brown v. Walker et al. in the same court against the same defendants.

On  December  12,  2019,  the  court  consolidated  the  Allred  and  Brown  actions  under  the  caption  In  re  Aclaris
Therapeutics, Inc. Derivative Litigation  (the  “Consolidated  Derivative  Action”)  and  directed  that  future  derivative  cases
filed in or transferred to the court arising out of substantially the same transactions or events be similarly consolidated. 
Thereafter,  on  January  11,  2020,  the  court  stayed  –  subject  to  certain  conditions  –  all  deadlines  in  the  Consolidated
Derivative Action pending resolution of the defendants’ anticipated motion to dismiss the Consolidated Securities Action.

The defendants dispute plaintiffs’ claims in the Consolidated Derivative Action and intend to defend the matter
vigorously.   At  this  time,  the  Company  cannot  reasonably  predict  the  outcome  or  potential  loss,  if  any,  that  could  result
from this matter.

Product Liability Lawsuit

On December 18, 2020, plaintiff Daurie Mancini filed an amended complaint under the caption Daurie Mancini v.
Aclaris Therapeutics, Inc. et al in the Superior Court of New Jersey Ocean County against the Company and certain third
parties alleging injuries as a result of the plaintiff’s alleged treatment with ESKATA in 2019. The amended complaint seeks
unspecified compensatory and punitive damages. On January 19, 2021, the Company’s deadline to answer, move against or
otherwise respond to the amended complaint was extended until March 15, 2021.

The Company disputes plaintiff’s claims and intends to defend the matter vigorously. At this time, the Company

cannot reasonably predict the outcome or potential loss, if any, that could result from this matter.

21. Subsequent Events

January 2021 Public Offering

In January 2021, the Company closed a public offering in which it sold 6,306,271 shares of common stock at a
price to the public of $17.50 per share, for aggregate gross proceeds of $110.4 million. The Company paid underwriting
discounts and commissions of $6.6 million, and also incurred expenses of $0.3 million in connection with the offering.  As
a  result,  the  net  offering  proceeds  received  by  the  Company,  after  deducting  underwriting  discounts,  commissions  and
offering expenses, were $103.5 million.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision of and with the participation of our management, including our chief executive officer, who
is our principal executive officer, and our chief financial officer, who is our principal financial officer, we conducted an
evaluation of the effectiveness of our disclosure controls and procedures as of December 31, 2020, the end of the period
covered by this Annual Report. The term “disclosure controls and procedures,” as set forth in Rules 13a-15(e) and 15d-
15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures
of a company that are designed to provide reasonable assurance that information required to be disclosed by a company in
the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time
periods  specified  in  the  rules  and  forms  promulgated  by  the  SEC.  Disclosure  controls  and  procedures  include,  without
limitation,  controls  and  procedures  designed  to  ensure  that  information  required  to  be  disclosed  by  a  company  in  the
reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management,
including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required
disclosure.  Management  recognizes  that  any  controls  and  procedures,  no  matter  how  well  designed  and  operated,  can
provide  only  reasonable  assurance  of  achieving  their  objectives,  and  management  necessarily  applies  its  judgment  in
evaluating  the  cost-benefit  relationship  of  possible  controls  and  procedures.  Based  on  the  evaluation  of  our  disclosure
controls and procedures as of December 31, 2020, our chief executive officer and chief financial officer concluded that, as
of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation
required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2020
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s  Report  on  Internal  Control  over  Financial  Reporting  and  Attestation  Report  of  the  Registered
Public Accounting Firm

Our  management  is  responsible  for  establishing  and  maintaining  an  adequate  system  of  internal  control  over
financial  reporting,  as  defined  in  Rule  13a-15(f)  of  the  Exchange  Act.  Management  conducted  an  assessment  of  our
internal  control  over  financial  reporting  based  on  the  framework  established  in  2013  by  the  Committee  of  Sponsoring
Organizations  of  the  Treadway  Commission  in  Internal  Control—Integrated  Framework.    Based  on  the  assessment,
management concluded that, as of December 31, 2020, our internal control over financial reporting was effective.

This  Annual  Report  does  not  include  an  attestation  report  of  our  registered  public  accounting  firm  regarding
internal control over financial reporting as required by Section 404(b) of the Sarbanes-Oxley Act of 2002. Because we are
a  smaller  reporting  company  and  a  non-accelerated  filer  under  the  SEC  rules,  management's  report  was  not  subject  to
attestation by our independent registered public accounting firm.

DESCRIPTION OF ACLARIS THERAPEUTICS, INC. CAPITAL STOCK

The following description of the common stock of Aclaris Therapeutics, Inc., or the Company, is a summary and does
not purport to be complete. This summary is qualified in its entirety by reference to the provisions of the Delaware
General Corporation Law, or the DGCL, and the complete text of the Company’s amended and restated certificate of
incorporation, or the certificate of incorporation, and amended and restated bylaws or the bylaws, which are
incorporated by reference as Exhibits 3.1 and 3.2, respectively of the Company’s Annual Report on Form 10-K to
which this description is also an exhibit. The Company encourages you to read that law and those documents carefully.

Common Stock

Under the certificate of incorporation, the Company authorized to issue up to 100,000,000 shares of common
stock, $0.00001 par value per share, and 10,000,000 shares of preferred stock, $0.00001 par value per share, all of
which shares of preferred stock are undesignated. The Company’s board of directors may establish the rights and
preferences of the preferred stock from time to time.

Voting Rights

Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the
stockholders, including the election of directors. Under the certificate of incorporation and the bylaws, common
stockholders do not have cumulative voting rights. Because of this, the holders of a majority of the shares of common
stock entitled to vote in any election of directors can elect all of the directors standing for election, if they should so
choose.

Dividends

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

Liquidation

In the event of the Company’s liquidation, dissolution or winding up, holders of common stock will be entitled to

share ratably in the net assets legally available for distribution to stockholders after the payment of all of debts and
other liabilities and the satisfaction of any liquidation preference granted to the holders of any then-outstanding shares
of preferred stock.

Rights and Preferences

Holders of common stock have no preemptive, conversion or subscription rights and there are no redemption or

sinking fund provisions applicable to the common stock. The rights, preferences and privileges of the holders of
common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of
preferred stock that the Company may designate in the future.

Anti-Takeover Provisions

Section 203 of the DGCL

The Company is subject to Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in

any business combination with any interested stockholder for a period of three years after the date that such
stockholder became an interested stockholder, with the following exceptions:

 
 
 
 
 
 
 
 
 
 
 
 
 
 
●                  before such date, the board of directors of the corporation approved either the business combination or the

transaction that resulted in the stockholder becoming an interested stockholder;

●                  upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the
transaction began, excluding for purposes of determining the voting stock outstanding, but not the outstanding
voting stock owned by the interested stockholder, those shares owned (i) by persons who are directors and
also officers and (ii) employee stock plans in which employee participants do not have the right to determine
confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
●                  on or after such date, the business combination is approved by the board of directors and authorized at an

annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least
66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 defines a “business combination” to include the following:

●                  any merger or consolidation involving the corporation and the interested stockholder;
●                  any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the

interested stockholder;

●                  subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any

stock of the corporation to the interested stockholder;

●                  any transaction involving the corporation that has the effect of increasing the proportionate share of the stock

or any class or series of the corporation beneficially owned by the interested stockholder; or

●                  the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other

financial benefits by or through the corporation.

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s

affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested
stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

Certificate of Incorporation and Bylaws

The certificate of incorporation provides for the Company’s board of directors to be divided into three classes with
staggered three-year terms. Only one class of directors will be elected at each annual meeting of stockholders, with the
other classes continuing for the remainder of their respective three-year terms. Because the Company’s stockholders do
not have cumulative voting rights, stockholders holding a majority of the shares of common stock outstanding will be
able to elect all of the Company’s directors. The certificate of incorporation and bylaws also provide that directors may
be removed by the stockholders only for cause upon the vote of 66 2/3% or more of outstanding common stock.
Furthermore, the authorized number of directors may be changed only by resolution of the board of directors, and
vacancies and newly created directorships on the board of directors may, except as otherwise required by law or
determined by the board, only be filled by a majority vote of the directors then serving on the board, even though less
than a quorum.

The certificate of incorporation and bylaws also provide that all stockholder actions must be effected at a duly
called meeting of stockholders and will eliminate the right of stockholders to act by written consent without a meeting.
The bylaws also provide that only the Company’s chairman of the board, chief executive officer or the board of
directors pursuant to a resolution adopted by a majority of the total number of authorized directors may call a special
meeting of stockholders.

The bylaws also provide that stockholders seeking to present proposals before a meeting of stockholders or to

nominate candidates for election as directors at a meeting of stockholders must provide timely advance notice in
writing, and specify requirements as to the form and content of a stockholder’s notice.

The certificate of incorporation and bylaws provide that the stockholders cannot amend many of the provisions

described above except by a vote of 66 2/3% or more of outstanding common stock.

 
 
 
 
 
 
 
 
 
The combination of these provisions make it more difficult for the Company’s existing stockholders to replace the

board of directors as well as for another party to obtain control of the Company by replacing its board of directors.
Since the Company’s board of directors has the power to retain and discharge the Company’s officers, these provisions
also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the
authorization of undesignated preferred stock makes it possible for the Company’s board of directors to issue preferred
stock with voting or other rights or preferences that could impede the success of any attempt to change the Company’s
control.

These provisions are intended to enhance the likelihood of continued stability in the composition of the

Company’s board of directors and its policies and to discourage coercive takeover practices and inadequate takeover
bids. These provisions are also designed to reduce the Company’s vulnerability to hostile takeovers and to discourage
certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others
from making tender offers for the Company’s shares and may have the effect of delaying changes in its control or
management. As a consequence, these provisions may also inhibit fluctuations in the market price of the Company’s
stock that could result from actual or rumored takeover attempts. The Company believes that the benefits of these
provisions, including increased protection of its potential ability to negotiate with the proponent of an unfriendly or
unsolicited proposal to acquire or restructure the company, outweigh the disadvantages of discouraging takeover
proposals, because negotiation of takeover proposals could result in an improvement of their terms.

Choice of Forum

The Company’s certificate of incorporation provides that the Court of Chancery of the State of Delaware is the
exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any
derivative action or proceeding brought on the Company’s behalf, (ii) any action asserting a claim for breach of a
fiduciary duty owed by any of the Company’s directors, officers or other employees to the Company or its
stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, the Company’s
certificate of incorporation or bylaws or (iv) any action asserting a claim governed by the internal affairs
doctrine. However, this exclusive forum provision would not apply to suits brought to enforce a duty or liability
created by the Securities Act of 1933, as amended, or the Securities Act, or the Securities Exchange Act of 1934, as
amended. 

In addition, the Company’s bylaws provide that unless the Company consents in writing to the selection of an
alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by
law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the
Securities Act, and that any person or entity purchasing or otherwise acquiring or holding any interest in shares of
capital stock of the Company shall be deemed to have notice of and consented to the federal forum selection provision.

The transfer agent’s address is 1717 Arch Street, Suite 1300, Philadelphia, Pennsylvania 19103.

must execute a general waiver and release in substantially the form attached hereto as Exhibit A, Exhibit B or Exhibit C, as
appropriate  (the  “Release”),  within  the  applicable  time  period  set  forth  therein,  but  in  no  event  more  than  fifty  (50)  days
following  the  Termination  Date  of  the  applicable  Covered  Termination,  and  such  Release  must  become  effective  in
accordance with its terms.  The

3.

Company, in its sole discretion, may modify the form of the Release to comply with applicable law.  The Release may be
incorporated into a termination agreement or other agreement with the employee.

(c)

No  Duplicative  Benefits  Provided  Under  Plan.    This  Plan  does  not  supersede  the  terms  of  any
Individual Severance Arrangement.  Unless otherwise determined by the Plan Administrator in its discretion, if an employee
is an Eligible Employee and otherwise eligible to receive severance benefits under this Plan that are of the same category
and  would  otherwise  duplicate  the  benefits  available  under  the  terms  of  any  Individual  Severance  Arrangement
(“Duplicative  Benefits”)  such  Eligible  Employee  will  receive  severance  benefits  under  the  Individual  Severance
Arrangement in lieu of any Plan benefits to the extent such benefits are Duplicative Benefits, and severance benefits will be
provided under the Plan only to the extent, if any, that Plan benefits are not Duplicative Benefits.

(d)

Exceptions to Benefit Entitlement.  An employee who otherwise is an Eligible Employee will not
receive  benefits  under  the  Plan  in  the  following  circumstances,  as  determined  by  the  Plan  Administrator  in  its  sole
discretion:

(1)

The  employee  is  terminated  by  the  Company  for  any  reason  (including  due  to  the
employee’s death or disability) or voluntarily terminates employment with the Company in any manner, and in either case,
such  termination  does  not  constitute  a  Covered  Termination.    Voluntary  terminations  include,  but  are  not  limited  to,
resignation, retirement or failure to return from a leave of absence on the scheduled date.

employment with another entity that is wholly or partly owned (directly or indirectly) by the Company or an Affiliate.

(2)

The  employee  voluntarily  terminates  employment  with  the  Company  in  order  to  accept

The employee is offered an identical or substantially equivalent or comparable position with
the Company or an Affiliate.  For purposes of the foregoing, a “substantially equivalent or comparable position” is one that
provides the employee substantially the same level of responsibility and compensation.

(3)

(4)

The  employee  is  offered  immediate  reemployment  by  a  successor  to  the  Company  or  an
Affiliate or by a purchaser of the Company’s assets, as the case may be, following a Change in Control  in a “substantially
equivalent or comparable position” as defined in Section 2(d)(3).  For purposes of the foregoing, “immediate reemployment”
means that the employee’s employment with the successor to the Company or an Affiliate or the purchaser of its assets, as
the case may be, results in uninterrupted employment such that the employee does not incur a lapse in pay or benefits as a
result of the change in ownership of the Company or the sale of its assets.  For the avoidance of doubt, an employee who
becomes immediately reemployed as described in this Section 2(d)(4) by a successor to the Company or an Affiliate or by a
purchaser  of  the  Company’s  assets,  as  the  case  may  be,  following  a  Change  in  Control  shall  continue  to  be  an  Eligible
Employee following the date of such reemployment.

prior to the date benefits under the Plan are scheduled to commence.

(5)

The  employee  is  rehired  by  the  Company  or  an  Affiliate  and  recommences  employment

Section 3.

AMOUNT OF BENEFIT.

(a)

Severance Benefit.  Benefits under the Plan shall be provided to an Eligible Employee as follows,

subject to any delay in payment that may be required by Section 5:

4.

(1)

Severance Pay.  The Eligible Employee will be entitled to receive a single lump sum cash
payment  equal  to  (A)  50%  of  the  Eligible  Employee’s  Annual  Base  Salary,  plus  (B)  an  amount  equal  to  the  Eligible
Employee’s  Target  Bonus,  pro-rated  based  on  the  number  of  days  actually  served  in  the  calendar  year  during  which  the
Termination Date occurs (the sum of (A) and (B), the “Severance Pay”).  The Severance Pay will be payable to the Eligible
Employee within ten (10) business days following the later of (i) the effective date of the Release, or (ii) the effective date of
the Closing.

(2)

Accelerated Vesting of Stock Awards.  Effective as of the later of the effective date of the
Release  or  the  effective  date  of  the  Closing,  to  the  extent  not  previously  vested:  (A)  the  vesting  and  exercisability  of  all
outstanding stock options to purchase the Company’s common stock that are held by the Eligible Employee on such date
shall  be  accelerated  in  full,  (B)  any  reacquisition  or  repurchase  rights  held  by  the  Company  in  respect  of  common  stock
issued pursuant to any other stock award granted to the Eligible Employee by the Company shall lapse in full, and (C) the
vesting of any other stock awards granted to the Eligible Employee by the Company, and any issuance of shares triggered by
the  vesting  of  such  stock  awards,  shall  be  accelerated  in  full;  provided,  however,  that  the  foregoing  provisions  shall  not
apply to stock awards issued under or held in any Qualified Plan.  For purposes of determining the number of shares that will
vest  pursuant  to  the  foregoing  provision  with  respect  to  any  performance  based  vesting  award  that  has  multiple  vesting
levels depending upon the level of performance, vesting acceleration shall occur with respect to the number of shares subject
to the award as if the applicable performance criteria had been attained at a 100% level.  In order to give effect to the intent
of  the  foregoing  provision,  notwithstanding  anything  to  the  contrary  set  forth  in  the  Eligible  Employee’s  stock  award
agreements or the applicable equity incentive plan under which such stock award was granted that provides that any then
unvested portion of the award will immediately expire upon the Eligible Employee’s termination of service, the stock awards
referred to in this Section 3(a)(2) shall remain outstanding after an Eligible Employee’s Covered Termination to the extent
necessary to give effect to the potential vesting acceleration in this Section 3(a)(2) (e.g., if an Eligible Employee’s Covered
Termination occurs prior to the Closing).  Notwithstanding anything to the contrary set forth herein, the Eligible Employee’s
  stock  awards  shall  remain  subject  to  the  terms  of  the  applicable  Company  plan  and  award  documents  under  which  such
stock  award  was  granted,  including  any  provision  for  earlier  termination  of  such  stock  awards  upon  a  “corporate
transaction,”  “change  in  control”  or  similar  event  under  the  terms  of  the  applicable  Company  equity  incentive  plan  or
substantially equivalent provisions applicable to such stock option or stock award.

(3)

Payment of Continued Group Health Plan Benefits.

(i)

Provided that the Eligible Employee is a participant in the Company’s group health
plans as of immediately prior to the Covered Termination, if the Eligible Employee timely elects continued group health plan
continuation  coverage  under  COBRA  with  respect  to  such  group  health  plans,  the  Company  shall  directly  pay  to  the
Company’s group health care provider an amount equal to the COBRA premiums, less the amount the Eligible Employee
would  have  had  to  pay  to  receive  group  health  coverage  for  the  Eligible  Employee  and  the  Eligible  Employee’s  covered
dependents based on the cost sharing levels in effect on the Eligible Employee’s Termination Date (which for the avoidance
of doubt the Eligible Employee shall be required to pay directly to the Company’s group health care provider together with
any  administrative  or  additional  costs  due  with  respect  to  such  COBRA  coverage),  for  the  Eligible  Employee  and  the
Eligible  Employee’s  covered  dependents  under  such  plans  during  the  period  commencing  on  the  Termination  Date  and
ending upon the last day of the six (6) month period following the Covered Termination (the “COBRA Payment Period”).
 Upon the conclusion of such period of insurance premium payments made by the Company, the Eligible Employee will be
responsible for the entire payment of premiums (or payment for the cost of coverage) required under

5.

COBRA for the duration of the Eligible Employee’s eligible COBRA coverage period.  For purposes of this Section, (A)
references to COBRA shall be deemed to refer also to analogous provisions of state law and (B) any applicable insurance
premiums that are paid by the Company shall not include any amounts payable by the Eligible Employee under an Internal
Revenue  Code  Section  125  health  care  reimbursement  plan,  which  amounts,  if  any,  are  the  Eligible  Employee’s  sole
responsibility.

(ii)

Notwithstanding the foregoing, if at any time the Company determines, in its sole
discretion,  that  it  cannot  provide  the  COBRA  premium  benefits  without  potentially  incurring  financial  costs  or  penalties
under applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then in lieu of paying
COBRA premiums on the Eligible Employee’s behalf, the Company will instead pay the Eligible Employee on the last day
of each remaining month of the COBRA Payment Period a fully taxable cash payment equal to the COBRA premium for
that month, subject to applicable tax withholding (such amount, the “Special Severance Payment”), such Special Severance
Payment  to  be  made  without  regard  to  the  Eligible  Employee’s  election  of  COBRA  coverage  or  payment  of  COBRA
premiums  and  without  regard  to  the  Eligible  Employee’s  continued  eligibility  for  COBRA  coverage  during  the  COBRA
Payment Period.  Such Special Severance Payment shall end upon expiration of the COBRA Payment Period.

(b)

Additional  Benefits.    Notwithstanding  the  foregoing,  the  Company  may,  in  its  sole  discretion,
provide benefits to employees who are not Eligible Employees (“Non-Eligible Employees”) chosen by the Board, in its sole
discretion,  and  the  provision  of  any  such  benefits  to  a  Non-Eligible  Employee  shall  in  no  way  obligate  the  Company  to
provide such benefits to any other Non-Eligible Employee, even if similarly situated.  If benefits under the Plan are provided
to a Non-Eligible Employee, references in the Plan to “Eligible Employee” (and similar references) shall be deemed to refer
to such Non-Eligible Employee.

(c)

Certain  Reductions.    The  Company,  in  its  sole  discretion,  shall  have  the  authority  to  reduce  an
Eligible Employee’s severance benefits, in whole or in part, by pay and benefits provided during a period following written
notice  of  a  plant  closing  or  mass  layoff,  pay  and  benefits  in  lieu  of  such  notice,  or  other  similar  benefits  payable  to  the
Eligible  Employee  by  the  Company  or  an  Affiliate  that  become  payable  in  connection  with  the  Eligible  Employee’s
termination  of  employment  pursuant  to  (i)  any  applicable  legal  requirement,  including,  without  limitation,  the  Worker
Adjustment and Retraining Notification Act or any other similar state law, (ii) any Company policy or practice providing for
the Eligible Employee to remain on the payroll for a limited period of time after being given notice of the termination of the
Eligible Employee’s employment, or (iii) any other severance benefit agreement or arrangement between the Company and
the Eligible Employee, and the Plan Administrator shall so construe and implement the terms of the Plan, in each case to the
extent compliant with Section 409A of the Code.  Any such reductions that the Company determines to make pursuant to
this Section 3(c) shall be made such that any benefit under the Plan shall be reduced solely by any similar type of benefit
under such legal requirement, agreement, policy or practice (i.e., any cash severance benefits under the Plan shall be reduced
solely  by  any  cash  payments  or  severance  benefits  under  such  legal  requirement,  agreement,  policy  or  practice,  and  any
continued  insurance  benefits  under  the  Plan  shall  be  reduced  solely  by  any  continued  insurance  benefits  under  such  legal
requirement, agreement, policy or practice).  The Company’s decision to apply such reductions to the severance benefits of
one  Eligible  Employee  and  the  amount  of  such  reductions  shall  in  no  way  obligate  the  Company  to  apply  the  same
reductions in the same amounts to the severance benefits of any other Eligible Employee, even if similarly situated.  In the
Company’s sole discretion, such reductions may be applied on a retroactive basis, with severance benefits previously paid
being re-characterized as payments pursuant to the Company’s statutory obligation.

6.

(d)

Parachute Payments.  The following provisions shall not supersede any provisions to the contrary

provided under any Individual Severance Arrangement, if applicable:

(1)

Any  provision  of  the  Plan  to  the  contrary  notwithstanding,  if  any  payment  or  benefit  an
Eligible Employee would receive from the Company pursuant to the Plan or otherwise (“Payment”) would (i) constitute a
“parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise
tax  imposed  by  Section  4999  of  the  Code  (the  “Excise Tax”),  then  such  Payment  will  be  equal  to  the  Reduced  Amount
(defined  below).    The  “Reduced  Amount”  shall  be  either  (x)  the  largest  portion  of  the  Payment  that  would  result  in  no
portion  of  the  Payment  being  subject  to  the  Excise  Tax  or  (y)  the  largest  portion,  up  to  and  including  the  total,  of  the
Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes,
and the Excise Tax (all computed at the highest applicable marginal rate), results in the Eligible Employee’s receipt, on an
after-tax basis, of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the
Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals
the  Reduced  Amount,  reduction  shall  occur  in  the  manner  that  results  in  the  greatest  economic  benefit  for  the  Eligible
Employee.    If  more  than  one  method  of  reduction  will  result  in  the  same  economic  benefit,  the  items  so  reduced  will  be
reduced pro rata.

(2)

In the event it is subsequently determined by the Internal Revenue Service that some portion
of the Reduced Amount as determined pursuant to clause (x) in the preceding paragraph is subject to the Excise Tax, the
Eligible Employee agrees to promptly return to the Company a sufficient amount of the Payment so that no portion of the
Reduced Amount is subject to the Excise Tax.  For the avoidance of doubt, if the Reduced Amount is determined pursuant to
clause (y) in the preceding paragraph, the Eligible Employee will have no obligation to return any portion of the Payment
pursuant to the preceding sentence.

(3)

Unless the Eligible Employee and the Company agree on an alternative accounting firm or
law  firm,  the  accounting  firm  engaged  by  the  Company  for  general  tax  compliance  purposes  as  of  the  day  prior  to  the
effective date of the Change in Control shall perform the foregoing calculations.  If the accounting firm so engaged by the
Company  is  serving  as  accountant  or  auditor  for  the  individual,  entity  or  group  effecting  the  Change  in  Control,  the
Company shall appoint a nationally recognized accounting or law firm to make the determinations required hereunder.  The
Company  shall  bear  all  expenses  with  respect  to  the  determinations  by  such  accounting  or  law  firm  required  to  be  made
hereunder.

Section 4.

RETURN OF COMPANY PROPERTY.

An  Eligible  Employee  will  not  be  entitled  to  any  severance  benefit  under  the  Plan  unless  and  until  the
Eligible  Employee  returns  all  Company  Property.    For  this  purpose,  “Company  Property”  means  all  Company  documents
(and all copies thereof) and other Company property which the Eligible Employee had in his or her possession at any time,
including, but not limited to, Company files, notes, drawings, records, plans, forecasts, reports, studies, analyses, proposals,
agreements, financial information, research and development information, sales and marketing information, operational and
personnel  information,  specifications,  code,  software,  databases,  computer-recorded  information,  tangible  property  and
equipment  (including,  but  not  limited  to,  computers,  facsimile  machines,  mobile  telephones,  servers),  credit  cards,  entry
cards, identification badges and keys; and any materials of any kind which contain or embody any proprietary or confidential
information of the Company (and all reproductions thereof in whole or in part).

7.

Section 5.

TAX WITHHOLDING; OFFSET; SECTION 409A.

All payments under the Plan will be subject to applicable withholding for federal, state and local taxes.  If an
Eligible Employee is indebted to the Company on his or her termination date, the Company reserves the right to offset any
severance payments under the Plan by the amount of such indebtedness.  All severance benefits provided under the Plan are
intended to satisfy the requirements for an exemption from application of Section 409A of the Code to the maximum extent
that an exemption is available and any ambiguities herein shall be interpreted accordingly.

Notwithstanding  anything  to  the  contrary  set  forth  herein,  any  payments  and  benefits  provided  under  the
Plan that constitute “deferred compensation” within the meaning of Section 409A of the Code and the regulations and other
guidance thereunder and any state law of similar effect (collectively “Section 409A”) shall not commence in connection with
an Eligible Employee’s termination of employment unless and until the Eligible Employee has also incurred a “separation
from service,” as such term is defined in Treasury Regulations Section 1.409A-1(h) (“Separation from Service”), unless the
Company reasonably determines that such amounts may be provided to the Eligible Employee without causing the Eligible
Employee to incur the adverse personal tax consequences under Section 409A.

It  is  intended  that  (i)  each  installment  of  any  benefits  payable  under  the  Plan  to  an  Eligible  Employee  be
regarded as a separate “payment” for purposes of Treasury Regulations Section 1.409A-2(b)(2)(i), (ii) all payments of any
such  benefits  under  the  Plan  satisfy,  to  the  greatest  extent  possible,  the  exemptions  from  the  application  of  Section  409A
provided under Treasury Regulations Sections 1.409A-1(b)(4) and 1.409A-1(b)(9)(iii), and (iii) any such benefits consisting
of  COBRA  premiums  also  satisfy,  to  the  greatest  extent  possible,  the  exemption  from  the  application  of  Section  409A
provided  under  Treasury  Regulations  Section  1.409A-1(b)(9)(v).    However,  if  the  Company  determines  that  any  such
benefits  payable  under  the  Plan  constitute  “deferred  compensation”  under  Section  409A  and  the  Eligible  Employee  is  a
“specified  employee”  of  the  Company,  as  such  term  is  defined  in  Section  409A(a)(2)(B)(i),  then,  solely  to  the  extent
necessary  to  avoid  the  imposition  of  the  adverse  personal  tax  consequences  under  Section  409A,  (A)  the  timing  of  such
benefit payments shall be delayed until the earlier of (1) the date that is six (6) months and one (1) day after the Eligible
Employee’s Separation from Service and (2) the date of the Eligible Employee’s death (such applicable date, the “Delayed
Initial Payment Date”), and (B) the Company shall (1) pay the Eligible Employee a lump sum amount equal to the sum of
the benefit payments that the Eligible Employee would otherwise have received through the Delayed Initial Payment Date if
the commencement of the payment of the benefits had not been delayed pursuant to this paragraph and (2) commence paying
the balance, if any, of the benefits in accordance with the applicable payment schedule.

In  no  event  shall  payment  of  any  benefits  under  the  Plan  be  made  prior  to  an  Eligible  Employee’s
Termination  Date  or  prior  to  the  effective  date  of  the  Release.    If  the  Company  determines  that  any  payments  or  benefits
provided  under  the  Plan  constitute  “deferred  compensation”  under  Section  409A,  and  the  Eligible  Employee’s  Separation
from  Service  occurs  at  a  time  during  the  calendar  year  when  the  Release  could  become  effective  in  the  calendar  year
following the calendar year in which the Eligible Employee’s Separation from Service occurs, then regardless of when the
Release  is  returned  to  the  Company  and  becomes  effective,  the  Release  will  not  be  deemed  effective  any  earlier  than  the
latest permitted effective date.

8.

Section 6.

REEMPLOYMENT.

In the event of an Eligible Employee’s reemployment by the Company during the period of time in respect
of  which  severance  benefits  pursuant  to  the  Plan  have  been  paid,  the  Company,  in  its  sole  and  absolute  discretion,  may
require  such  Eligible  Employee  to  repay  to  the  Company  all  or  a  portion  of  such  severance  benefits  as  a  condition  of
reemployment.

Section 7.

TRANSFER AND ASSIGNMENT.

The  rights  and  obligations  of  an  Eligible  Employee  under  this  Plan  may  not  be  transferred  or  assigned  without  the  prior
written  consent  of  the  Company.    The  Plan  shall  be  binding  upon  any  entity  or  person  who  is  a  successor  by  merger,
acquisition, consolidation or otherwise to the business formerly carried on by the Company without regard to whether or not
such entity or person actively assumes the obligations hereunder and without regard to whether or not a Change in Control
occurs.

Section 8.

RIGHT TO INTERPRET AND ADMINISTER PLAN; AMENDMENT AND TERMINATION.

(a)

Interpretation  and  Administration.    Prior  to  the  Closing,  the  Board  shall  be  the  Plan
Administrator  and  shall  have  the  exclusive  discretion  and  authority  to  establish  rules,  forms,  and  procedures  for  the
administration of the Plan and to construe and interpret the Plan and to decide any and all questions of fact, interpretation,
definition, computation or administration arising in connection with the operation of the Plan, including, but not limited to,
the eligibility to participate in the Plan and amount of benefits paid under the Plan.  The rules, interpretations, computations
and other actions of the Board shall be binding and conclusive on all persons.  Upon and after the Closing, the Plan will be
interpreted  and  administered  in  good  faith  by  the  Representative  who  shall  be  the  Plan  Administrator  during  such  period.
 All actions taken by the Representative in interpreting the terms of the Plan and administering the Plan upon and after the
Closing  will  be  final  and  binding  on  all  Eligible  Employees.    Any  references  in  this  Plan  to  the  “Board”  or  “Plan
Administrator” with respect to periods following the Closing shall mean the Representative.

(b)

Amendment.    The  Plan  Administrator  reserves  the  right  to  amend  this  Plan  at  any  time  in  its
discretion; provided, however, that any amendment of the Plan that would adversely affect a particular employee will not be
effective as to such employee without his or her written consent if at the time of such amendment such employee previously
has been terminated in a Covered Termination.

(c)

Termination.  The  Plan  will  automatically  terminate  following  satisfaction  of  all  the  Company’s
obligations  under  the  Plan.    The  Plan  may  be  earlier  terminated  at  any  time  at  the  discretion  of  the  Plan  Administrator,
provided, however, that no such discretionary termination by the Plan Administrator may be implemented with respect to
any employee without his or her written consent if at such time the employee previously has been terminated in a Covered
Termination.

Section 9.

NO IMPLIED EMPLOYMENT CONTRACT.

The Plan shall not be deemed (i) to give any employee or other person any right to be retained in the employ
of the Company or (ii) to interfere with the right of the Company to discharge any employee or other person at any time,
with or without cause, which right is hereby reserved.

9.

Section 10.

LEGAL CONSTRUCTION.

This Plan is intended to be governed by and shall be construed in accordance with the Employee Retirement
Income  Security  Act  of  1974  (“ERISA”)  and,  to  the  extent  not  preempted  by  ERISA,  the  laws  of  the  Commonwealth  of
Pennsylvania.

(b)

Denial of Claims.  In the event that any application for benefits is denied in whole or in part, the
Plan Administrator must provide the applicant with written or electronic notice of the denial of the application, and of the
applicant’s  right  to  review  the  denial.   Any  electronic  notice  will  comply  with  the  regulations  of  the  U.S.  Department  of
Labor.  The notice of denial will be set forth in a manner designed to be understood by the applicant and will include the
following:

(4)

This  notice  of  denial  will  be  given  to  the  applicant  within  ninety  (90)  days  after  the  Plan  Administrator
receives the application, unless special circumstances require an extension of time, in which case, the Plan Administrator has
up to an additional ninety (90) days for processing the application.  If an extension of time for processing is required, written
notice of the extension will be furnished to the applicant before the end of the initial ninety (90) day period.

This  notice  of  extension  will  describe  the  special  circumstances  necessitating  the  additional  time  and  the

date by which the Plan Administrator is to render its decision on the application.

(c)

Request  for  a  Review.    Any  person  (or  that  person’s  authorized  representative)  for  whom  an
application for benefits is denied, in whole or in part, may appeal the denial by submitting a request for a review to the Plan
Administrator within sixty (60) days after the application is denied.  A request for a review shall be in writing and shall be
addressed to:

10.

Aclaris Therapeutics, Inc.
Board of Directors
101 Lindenwood Drive, Suite 400
Malvern, PA 19355

A request for review must set forth all of the grounds on which it is based, all facts in support of the request and any other 
matters that the applicant feels are pertinent.  The applicant (or his or her representative) shall have the opportunity to submit 
(or the Plan Administrator may require the applicant to submit) written comments, documents, records, and other 
information relating to his or her claim.  The applicant (or his or her representative) shall be provided, upon request and free 
of charge, reasonable access to, and copies of, all documents, records and other information relevant to his or her claim.  The 
review shall take into account all comments, documents, records and other information submitted by the applicant (or his or 
her representative) relating to the claim, without regard to whether such information was submitted or considered in the 
initial benefit determination.

(d)

Decision on Review.  The Plan Administrator will act on each request for review within sixty (60)
days after receipt of the request, unless special circumstances require an extension of time (not to exceed an additional sixty
(60) days), for processing the request for a review.  If an extension for review is required, written notice of the extension will
be  furnished  to  the  applicant  within  the  initial  sixty  (60)  day  period.    This  notice  of  extension  will  describe  the  special
circumstances necessitating the additional time and the date by which the Plan Administrator is to render its decision on the
review.  The Plan Administrator will give prompt, written or electronic notice of its decision to the applicant. Any electronic
notice will comply with the regulations of the U.S. Department of Labor.  In the event that the Plan Administrator confirms

a statement of the applicant’s right to bring a civil action under Section 502(a) of ERISA.

(e)

Rules and Procedures.  The Plan Administrator will establish rules and procedures, consistent with
the Plan and with ERISA, as necessary and appropriate in carrying out its responsibilities in reviewing benefit claims.  The
Plan Administrator may require an applicant who wishes to submit additional information in connection with an appeal from
the denial of benefits to do so at the applicant’s own expense.

(f)

Exhaustion  of  Remedies.    No  legal  action  for  benefits  under  the  Plan  may  be  brought  until  the
applicant (i) has submitted a written application for benefits in accordance with the procedures described by Section 11(a)
above, (ii) has been notified by the Plan Administrator that the application is denied, (iii) has filed a written request for a
review  of  the  application  in  accordance  with  the  appeal  procedure  described  in  Section  11(c)  above,  and  (iv)  has  been
notified that the Plan Administrator has denied the appeal.  Notwithstanding the foregoing, if the Plan Administrator does

Examine, without charge, at the Plan Administrator’s office and at other specified locations,
such as worksites, all documents governing the Plan and a copy of the latest annual report (Form 5500 Series), if applicable,

Security Administration;

Obtain, upon written request to the Plan Administrator, copies of documents governing the

(b)

Prudent  Actions  by  Plan  Fiduciaries.    In  addition  to  creating  rights  for  Eligible  Employees,
ERISA imposes duties upon the people who are responsible for the operation of the employee benefit plan.  The people who
operate the Plan, called “fiduciaries” of the Plan, have a duty to do so prudently and in the interest of you and other Eligible
Employees and beneficiaries.  No one, including your employer, your union or any other person, may fire you or otherwise
discriminate against you in any way to prevent you from obtaining a Plan benefit or exercising your rights under ERISA.

(c)

Enforce Your Rights.  If your claim for a Plan benefit is denied or ignored, in whole or in part, you
have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal
any denial, all within certain time schedules.

Under ERISA, there are steps you can take to enforce the above rights.  For instance, if you request
a copy of Plan documents or the latest annual report from the Plan, if applicable, and do not receive them within thirty (30)
days,  you  may  file  suit  in  a  Federal  court.    In  such  a  case,  the  court  may  require  the  Plan  Administrator  to  provide  the
materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent because of reasons
beyond the control of the Plan Administrator.

If you have a claim for benefits which is denied or ignored, in whole or in part, you may file suit in

If  you  are  discriminated  against  for  asserting  your  rights,  you  may  seek  assistance  from  the  U.S.
Department of Labor, or you may file suit in a Federal court.  The court will decide who should pay court costs and legal
fees.  If you are successful, the court may order the person you have sued to pay these costs and fees.  If you lose, the court
may order you to pay these costs and fees, for example, if it finds your claim is frivolous.

13.

(d)

Assistance with Your Questions.  If you have any questions about the Plan, you should contact the
Plan  Administrator.    If  you  have  any  questions  about  this  statement  or  about  your  rights  under  ERISA,  or  if  you  need
assistance  in  obtaining  documents  from  the  Plan  Administrator,  you  should  contact  the  nearest  office  of  the  Employee
Benefits Security Administration, U.S. Department of Labor, listed in your telephone directory or the Division of Technical
