SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This  Annual  Report  on  Form  10-K,  including  the  section  entitled  “Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations,”  contains
forward-looking  statements  regarding  future  events  and  our  future  results  that  are  subject  to  the  safe  harbors  created  under  the  Securities  Act  of  1933,  as  amended,  or  the
Securities  Act,  and  the  Securities  Exchange  Act  of  1934,  as  amended,  or  the  Exchange  Act.  Forward-looking  statements  relate  to  future  events  or  our  future  financial
performance.  We  generally  identify  forward-looking  statements  by  terminology  such  as  “may,”  “will,”  “would,”  “should,”  “expects,”  “plans,”  “anticipates,”  “could,”
“intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “assume,” “intend,” “potential,” “continue” or other similar words or the negative of
these  terms.  We  have  based  these  forward-looking  statements  largely  on  our  current  expectations  about  future  events  and  financial  trends  that  we  believe  may  affect  our
business,  financial  condition  and  results  of  operations.  The  outcome  of  the  events  described  in  these  forward-looking  statements  is  subject  to  risks,  uncertainties  and  other
factors described in “Risk Factors” and elsewhere in this report. Accordingly, you should not place undue reliance upon these forward-looking statements. We cannot assure
you that the events and circumstances reflected in the forward-looking statements will be achieved or occur, the timing of events and circumstances and actual results could
differ materially from those anticipated in the forward-looking statements. Forward-looking statements contained in this report include, but are not limited to, statements about:

  ●

the progress of, outcome or and timing of any regulatory approval for any of our product candidates and the expected amount or timing of any payment related thereto
under any of our collaboration agreements;

  ● the progress of, timing of and expected amount of expenses associated with our research, development and commercialization activities;

  ● our ability to raise additional funds on commercially reasonable terms, or at all, in order to support our continued operations;

  ● the sufficiency of our cash resources to fund our operating expenses and capital investment requirements for any period;

  ● the expected timing of our clinical trials for our product candidates and the availability of data and results of those trials;

  ● our expectations regarding federal, state and foreign regulatory requirements;

  ● the potential therapeutic benefits and effectiveness of our products and product candidates;

  ● the size and characteristics of the markets that may be addressed by our products and product candidates;

  ● our intention to seek to establish, and the potential benefits to us from, any strategic collaborations or partnerships for the development or sale of our products and

product candidates;

  ● our expectations as to future financial performance, expense levels and liquidity sources;

  ● the timing of commercializing our products and product candidates; and

  ● other factors discussed elsewhere in this report.

The forward-looking statements made in this report relate only to events as of the date on which the statements are made. We have included important factors in the cautionary
statements included in this report, particularly in the section entitled “Risk Factors” that we believe could cause actual results or events to differ materially from the forward-
looking  statements  that  we  make.  Our  forward-looking  statements  do  not  reflect  the  potential  impact  of  any  future  acquisitions,  mergers,  dispositions,  joint  ventures  or
investments we may make. Except as required by law, we do not assume any intent to update any forward-looking statements after the date on which the statement is made,
whether as a result of new information, future events or circumstances or otherwise.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
RISK FACTORS SUMMARY

The risk factors summarized below could materially harm our business, operating results, and/or financial condition, impair our future prospects, and/or cause the price of our
common stock to decline. These risks are discussed more fully in the section titled "Risk Factors". Material risks that may affect our business, financial condition, results of
operations, and trading price of our common stock include the following:

● Our research and development activities are focused on discovering and developing proprietary prodrugs, and we are taking an innovative approach to discovering and

developing prodrugs, which may never lead to marketable prodrug products.

● If we are not able to obtain required regulatory approvals for our product candidates, or the approved labels are not sufficiently differentiated from other competing

products, we will not be able to commercialize them and our ability to generate revenue or profits or to raise future capital could be limited.

  ●

If commercialization of AZSTARYS, APADAZ or our other product candidates is not successful, or we experience significant delays in commercialization, our business
will be harmed.

  ●

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 and commercialization of our product candidates.

  ●

We may need substantial additional funding to pursue our business objectives. If we are unable to raise capital when needed, we could be forced to delay, reduce or
altogether cease our prodrug development programs or commercialization efforts or cease operations altogether.

  ●

We have incurred significant recurring negative net operating losses since our inception. We expect to incur operating losses over the next several years and may never
achieve or maintain profitability.

● If we are unable to obtain and maintain trade secret protection or patent protection for our technology, AZSTARYS, KP879 and our other product 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 commercialize our technology, AZSTARYS, KP879 and our other product candidates, if approved, may be impaired.

● If we, subject to the approval of Commave Therapeutics, S.A., or Commave, themselves, attempt to rely on Section 505(b)(2) of the Federal Food, Drug and Cosmetic
Act and the FDA does not conclude that our product candidates are sufficiently bioequivalent, or have comparable bioavailability, to approved drugs, or if the FDA does
not allow us or Commave to pursue the 505(b)(2) NDA pathway as anticipated, the approval pathway for our product candidates will likely take significantly longer,
cost significantly more and entail significantly greater complications and risks than anticipated, and the FDA may not ultimately approve our product candidates.

  ●

The FDA may determine that any NDA we may submit under the 505(b)(2) regulatory pathway for any of our product candidates in the future is not sufficiently complete
to permit a substantive review.

● We  have  entered  into  collaborations  with  Commave  to  develop,  manufacture  and  commercialize  AZSTARYS  and  KP484  worldwide.  In  addition,  we  may  seek
collaborations  with  third  parties  for  the  development  or  commercialization  of  our  other  product  candidates,  or  in  other  territories.  If  those  collaborations  are  not
successful, we may not be able to capitalize on the market potential of AZSTARYS or KP484 or other product candidates, if approved.

  ● The trading price of the shares of our common stock is likely to be volatile, and purchasers of our common stock could incur substantial losses.

ITEM 1. BUSINESS.

Overview

PART I

We  are  a  specialty  pharmaceutical  company  focused  on  the  discovery  and  development  of  proprietary  prodrugs  to  treat  serious  medical  conditions  through  our  proprietary
Ligand Activated Therapy, or LAT®, technology. We utilize our proprietary LAT technology to generate improved prodrug versions of drugs approved by the U.S. Food and
Drug Administration, or FDA, as well as to generate prodrug versions of existing compounds that may have applications for new disease indications. Our product candidate
pipeline is focused on the high need areas of attention deficit hyperactivity disorder, or ADHD, and stimulant use disorder, or SUD, and idiopathic hypersomnia, or IH. Our
newly approved product, AZSTARYS™, formerly referred to as KP415, and KP484, are both based on a prodrug of d-methylphenidate, or d-MPH, but with differing extended-
release, or ER, effect profiles, and are intended for the treatment of ADHD. Our lead clinical development product candidate, KP879, is also based on a prodrug of d-MPH and
is intended for the treatment of stimulant use disorder, or SUD. Our preclinical prodrug product candidate for the treatment of ideopathic hypersomnia, or IH, is KP1077. We
have entered into a collaboration and license agreement with Commave Therapeutics SA (formerly known as Boston Pharmaceuticals S.A.), an affiliate of Gurnet Point Capital,
or Commave, for the development, manufacture and commercialization of AZSTARYS, and any other of our product candidates containing serdexmethylphenidate, or SDX,
and  d-MPH.    In  addition,  we  have  entered  into  a  commercial  partnership  with  KVK-Tech,  Inc.,  or  KVK,  for  APADAZ®,  an  FDA  approved  immediate-release,  or  IR,
combination product of benzhydrocodone, our prodrug of hydrocodone, and acetaminophen, or APAP, for the short-term (no more than 14 days) management of acute pain
severe enough to require an opioid analgesic and for which alternative treatments are inadequate.

On March 2, 2021, we announced that the FDA approved the NDA for AZSTARYS, a once-daily product for the treatment of ADHD in patients ranging from six years and
older. Corium will lead the commercialization of AZSTARYS per the KP415 License Agreement. Corium expects to make AZSTARYS commercially available in the U.S. as
early as the second half of 2021.

In July 2020, we entered into a consultation services arrangement, or the Corium Consulting Agreement, with Corium, Inc., or Corium, under which Corium engaged us to
guide the product development and regulatory activities for certain current and potential future products in Corium’s portfolio, as well as to continue supporting preparation for
the potential commercial launch of AZSTARYS. Corium is a portfolio company of Gurnet Point Capital and has been tasked with leading all commercialization activities for
AZSTARYS under the KP415 License Agreement.

In  September  2019,  we  entered  into  our  collaboration  and  license  agreement,  or  the  KP415  License  Agreement,  with  Commave,  for  the  development,  manufacture  and
commercialization of our product candidates containing SDX and d-MPH, including AZSTARYS and KP484.  In addition, the KP415 License Agreement provides Commave a
right  of  first  negotiation  upon  the  completion  of  a  Phase  1  proof-of-concept  study  for  KP879,  KP922  or  any  other  product  candidate  developed  by  us  containing  SDX  and
intended to treat ADHD or any other central nervous system disorder.

In  October  2018,  we  entered  into  our  collaboration  and  license  agreement,  or  the  APADAZ  License  Agreement,  with  KVK.  Under  the  APADAZ  License  Agreement,  we
granted an exclusive license to KVK to conduct regulatory activities for, manufacture and commercialize APADAZ in the United States. In collaboration with KVK, APADAZ
was first available for sale nationally beginning in November 2019.  In December 2020, KVK, began a regional pilot launch of APADAZ in the state of Alabama, with plans to
expand into additional geographic regions during 2021.

We employ our proprietary LAT technology to discover and develop prodrugs that are new molecules that can improve one or more of the attributes of approved drugs, such as
enhanced  bioavailability,  extended  duration  of  action,  increased  safety  and  reduced  susceptibility  to  abuse.  A  prodrug  is  a  precursor  chemical  compound  of  a  drug  that  is
inactive or less than fully active, which is then converted in the body to the active form of the drug through a normal metabolic process. Where possible, we seek, to develop
prodrugs that will be eligible for approval under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act, or the FFDCA, otherwise known as a 505(b)(2) NDA, which
allows us to rely on the FDA’s previous findings of safety and effectiveness for one or more approved products, if we demonstrate such reliance is scientifically appropriate.

We intend to advance our pipeline of product candidates for the treatment of ADHD, SUD and IH, and we anticipate initiating a Phase 1 proof-of-concept study for KP879 in
2021. We plan to employ our LAT technology and development expertise to develop additional product candidates that address significant unmet medical needs in therapeutic
indications which have few existing product options. We believe our product candidates may be eligible for composition-of-matter patent protection and we intend to use the
505(b)(2) NDA pathway when available, which we believe has the potential to reduce drug development time, risk and expense.

Our Proprietary LAT Technology

We  employ  our  proprietary  LAT  technology  to  create  prodrugs  that  are  new  molecules  by  chemically  attaching  one  or  more  molecules,  referred  to  as  ligands,  to  an  FDA-
approved parent drug. We typically use ligands that have been demonstrated to be safe in toxicological studies or have been granted Generally Recognized as Safe, or GRAS,
status by the FDA. When the prodrug is administered, human metabolic processes, such as those in the gastrointestinal, or GI, tract, separate the ligand from the prodrug and
release the parent drug, which can then exert its therapeutic effect. We select ligands that, when combined with the parent drug, create prodrugs believed to have improved drug
attributes while maintaining efficacy potentially equivalent to the parent drug.

We believe that our proprietary LAT technology offers the following potential benefits:

● Improved drug properties. We seek to discover and develop prodrugs that are new molecules with potentially improved attributes over FDA-approved drugs, such as

enhanced bioavailability, extended duration of action, increased safety and reduced susceptibility to abuse.

● Composition-of-matter patent protection. Our prodrugs are new molecules and thus may be eligible for patent protection as novel compositions of matter, provided that
all other applicable requirements are met. We seek patent protection not only for our product candidates, but also for related compounds with the intention of creating
potential heightened barriers to market entry.

● Eligibility for 505(b)(2) NDA pathway. Our proprietary LAT technology allows us to discover and develop prodrugs that may be eligible to use the 505(b)(2) NDA
pathway. Under that regulatory pathway, if we are able to provide an adequate bridge between our product candidates and appropriate FDA-approved drugs, we will then
be able to reference the FDA’s previous findings of safety and effectiveness of the approved drugs in our 505(b)(2) NDA submissions. This may allow us to avoid the
significant time and expense of conducting large clinical trials and potentially eliminate the need for some preclinical activities.

The Unmet Need for Addressing Early Morning Behavioral Deficits and Maintaining Consistent, Sustained Efficacy in Daily ADHD Treatment

The ADHD market is relatively well-served by a number of methylphenidate and amphetamine stimulant products. However, we believe there is a significant need for longer
duration products. While a few of the currently-marketed methylphenidate products are labeled as providing some level symptom control for up to 12 hours post-dose, there is
increasing attention to addressing late afternoon/early evening behavioral deficits, while also providing symptom control sooner following dosing.

A study published in a peer-reviewed journal characterized the frequency and severity of ADHD symptoms throughout the day in children and adolescents treated with stable
doses of stimulant medications. Results of that particular study indicated that the time from awakening to arriving at school can comprise up to 20% of waking hours per day (2-
3 hours), and therefore such symptoms can cause significant distress for both children and caregivers. As a result, we believe there is a need to develop a methylphenidate
product that provides early-morning control of symptoms.

In  addition  to  early  onset,  patients  require  sustained,  consistent  efficacy  throughout  the  day  and  into  the  early  evening  hours.  While  currently  marketed  methylphenidate
products offer efficacy for up to 12 hours, this duration may not be sufficient for all patients. Particularly adolescents and adults may often require longer effects as they have
longer waking hours compared to younger patients. It has been reported in a peer-reviewed journal that these patients are typically using dose-augmentation strategies by taking
additional doses of stimulant later in the day. We believe a single dose therapy that provides effective symptom control without requiring additional doses may have several
benefits including, potentially, improved dosage compliance by regularly and consistently taking medication as indicated, reduced social embarrassment by avoiding the need to
take medication during working hours, and overall improvement in quality of life through more consistent therapy. Based on this evidence, we believe there is a need to develop
a  methylphenidate  product  that  can  deliver  long  duration  of  efficacy.  There  may  also  be  a  need  to  develop  a  long-duration  stimulant  with  and  without  very  early  onset
depending on individual patient preference and requirements.

Our Product Candidates and Approved Products

We have employed our proprietary LAT technology to create a portfolio of product candidates and approved products that we believe will offer significant improvements over
FDA-approved and widely-prescribed drugs.

AZSTARYS and KP484

Overview

The prodrug in both AZSTARYS and KP484 is serdexmethylphenidate, or SDX, and both product candidates are intended for the treatment of ADHD. The ADHD market is
largely served by the stimulant products methylphenidate and amphetamine. Both AZSTARYS and KP484 are designed to be extended-duration methylphenidate products.

On March 2, 2021, we announced that the FDA approved the NDA for AZSTARYS, a once-daily product for the treatment of ADHD in patients ranging from six years and
older. Subject to Commave’s approval, we intend to seek approval of KP484 under the 505(b)(2) NDA pathway, which will allow us to rely on the FDA’s previous findings of
safety and effectiveness for one or more approved products. The timing for initiating additional PK and pivotal efficacy trials for KP484 is subject to Commave’s direction as
provided under the KP415 License Agreement.

In September 2019, we entered into the KP415 License Agreement with Commave. Under the KP415 License Agreement, we granted to Commave an exclusive, worldwide
license to develop, manufacture and commercialize our product candidates containing SDX and d-MPH, including AZSTARYS and KP484.  In addition, the KP415 License
Agreement  provides  a  right  of  first  negotiation  upon  completion  of  a  Phase  1  proof-of-concept  study  for  KP879,  KP922  or  any  other  product  candidate  developed  by  us
containing  SDX  and  developed  to  treat  ADHD  or  any  other  central  nervous  system  disorder,  or  the  Additional  Product  Candidates  and,  collectively  with  AZSTARYS  and
KP484, the Licensed Product Candidates.

Under  the  terms  of  the  KP415  License  Agreement,  we  granted  Commave  an  exclusive,  worldwide  license  to  commercialize  and  develop  the  Licensed  Product  Candidates;
provided  that  such  license  shall  apply  to  an  Additional  Product  Candidates  only  if  Commave  exercises  its  option  under  the  KP415  License  Agreement  related  thereto.  If
Commave exercises its right to first negotiation related to any Additional Product Candidate under the KP415 License Agreement, the parties are obligated to negotiate in good
faith regarding the economic terms of such Additional Product Candidate.

We also granted to Commave a right of first refusal to acquire, license or commercialize any Additional Product Candidate, with such right of first refusal expiring upon the
acceptance of a new drug application for such Additional Product Candidate. In addition, we granted Commave a right of first negotiation and a right of first refusal, subject to
specified exceptions, for any assignment of our rights under the KP415 License Agreement.

Pursuant to the KP415 License Agreement, Commave paid us an upfront payment of $10.0 million and agreed to pay up to $63.0 in milestone payments upon the occurrence of
specified regulatory milestones related to the AZSTARYS, including FDA approval and specified conditions with respect to the final approval label, and KP484. As a result of
the  FDA’s  approval  of  the  AZSTARYS  NDA,  we  have  earned  a  regulatory  milestone  payment  following  FDA  approval  as  provided  under  the  KP415  License  Agreement,
and we have invoiced Commave for such payment, which is payable within thirty (30) days following the PDUFA date for AZSTARYS, which was March 2, 2021.  In addition,
Commave agreed to make additional payments upon the achievement of specified U.S. sales milestones of up to $420.0 million in the aggregate. Further, Commave will pay us
quarterly, tiered royalty payments ranging from a percentage in the high single digits to the mid-twenties of Net Sales (as defined in the KP415 License Agreement) in the
United States and a percentage in the low to mid-single digits of Net Sales in each country outside the United States, in each case subject to specified reductions under certain
conditions as described in the KP415 License Agreement. Commave is obligated to make such royalty payments on a product-by-product basis until expiration of the Royalty
Term (as defined in the KP415 License Agreement) for the applicable product.

Commave agreed to be responsible for and reimburse us for all of development, commercialization and regulatory expenses for the Licensed Product Candidates, subject to
certain limitations as set forth in the KP415 License Agreement, including consultation fees to be paid to us for services provided to Commave in performing such activities.

The KP415 License Agreement will continue on a product-by-product basis (i) until expiration of the Royalty Term for the applicable Licensed Product Candidate in the United
States  and  (ii)  perpetually  for  all  other  countries.  Commave  may  terminate  the  KP415  License  Agreement  at  its  convenience  upon  prior  written  notice  prior  to  regulatory
approval of any Licensed Product Candidate or upon prior written notice after regulatory approval of any Licensed Product Candidate. We may terminate the KP415 License
Agreement in full if Commave, any of its sublicensees or any of its or their affiliates challenge the validity of any Licensed Patent (as defined in the KP415 License Agreement)
and such challenge is not required under a court order or subpoena and is not a defense against a claim, action or proceeding asserted by us. Either party may terminate the
KP415  License  Agreement  (i)  upon  a  material  breach  of  the  KP415  License  Agreement  by  the  other  party,  subject  to  a  cure  period,  or  (ii)  if  the  other  party  encounters
bankruptcy or insolvency. Upon a Serious Material Breach (as defined in the KP415 License Agreement) by us, subject to a cure period, Commave may choose not to terminate
the KP415 License Agreement and instead reduce the milestone and royalty payments owed to us. Upon termination, all licenses and other rights granted by us to Commave
pursuant to the KP415 License Agreement would revert to us. During the term of the KP415 License Agreement, we may not develop or commercialize any Competing Product
(as defined in the KP415 License Agreement).

The KP415 License Agreement established a joint steering committee, which monitors progress in the development of both AZSTARYS and KP484. Subject to the oversight of
the joint steering committee, we otherwise retain all responsibility for the conduct of all regulatory activities required to obtain NDA approval of both AZSTARYS and KP484;
provided that Commave shall be the sponsor of any clinical trials conducted by us on behalf of Commave.

Under our March 2012 asset purchase agreement with Shire, Shire had a right of first refusal to acquire, license or commercialize AZSTARYS and KP484. In January 2019,
Shire was acquired by Takeda to whom this right of first refusal was transferred at that time. Takeda did not exercise this right of first refusal as part of the KP415 License
Agreement.

Under our March 2012 termination agreement with Aquestive, Aquestive has the right to receive a royalty amount equal to 10% of any value generated by AZSTARYS, KP484
or KP879, and any product candidates which contain SDX, including royalty payments on any license of AZSTARYS, KP484 or KP879, the sale of AZSTARYS, KP484 or
KP879 to a third party, the commercialization of AZSTARYS, KP484 or KP879 and the portion of any consideration that is attributable to the value of AZSTARYS, KP484 or
KP879 and paid to us or our stockholders in a change of control transaction. In connection with the KP415 License Agreement, we paid Aquestive a royalty equal to 10% of the
upfront license payment we received in the third quarter of 2019 and the regulatory milestone payment we received in the second quarter of 2020.  Aquestive will be due to
receive a royalty equal to 10% of the of the regulatory milestone payment for the approval of the AZSTARYS NDA upon receipt from Commave.

Market Opportunity

We believe the ADHD market would be receptive to new branded drugs that have improved properties when compared to current treatments. We believe a new product in the
form of a prodrug that has differentiated features may provide a new treatment option in this large market segment. While methylphenidate is available as a generic product, the
branded  formulations,  including,  among  others,  CONCERTA,  FOCALIN  XR,  JORNAY  PM,  QUILLICHEW  XR  and  COTEMPLA  XR-ODT  rely  on  formulation  alone  in
attempting to provide differentiation from generics.

Key Features of AZSTARYS

We believe AZSTARYS has valuable product features and may provide significant benefits to patients, physicians, and society when compared to other FDA-approved and
widely-prescribed methylphenidate products:

  ● Earlier onset and extended duration.

  ● Once-daily dosing.

  ● Available to treat patients six years and older.

● Amenable to patient-friendly formulations. Patients can take AZSTARYS with or without food and can swallow capsules whole or open and sprinkle onto food or add

to water.

● Composition-of-matter  patent  protection.  We  have  a  U.S.  composition-of-matter  patent  that  will  expire,  after  utilizing  all  appropriate  patent  term  adjustments  but
excluding possible term extensions, in 2037 that generally covers at least one component of AZSTARYS. Our patent strategy is focused primarily on key geographic
markets,  and  we  have  composition-of-matter  patents  in  multiple  countries,  including  in  Canada,  China,  Europe,  Malaysia,  Mexico,  Indonesia,  Israel,  Japan,  New
Zealand, Philippines, Russia, Singapore, South Africa, South Korea and Vietnam, and additional patent filings pending in the United States and foreign jurisdictions.

● No generic equivalent product. AZSTARYS contains a prodrug that was given a new chemical name, serdexmethylphenidate, by the U.S. Adopted Names Council, or
USAN, which means that there may be no generic equivalent product for AZSTARYS in most states, making drug-equivalent substitution potentially difficult at the
pharmacy.

KP879

KP879, a prodrug of d-methylphenidate using our proprietary LAT technology, is our product candidate for the treatment of SUD including, for example, abuse or misuse of
cocaine,  methamphetamine  and  prescription  stimulants.  Currently  there  are  no  approved  drugs  in  the  United  States  for  SUD.  We  filed  an  IND  with  the  FDA  for  KP879  in
December 2020. In January 2021, the FDA completed its review of the KP879 IND, concluding that we may proceed with its planned clinical investigation of the product
candidate. We expect to initiate the clinical program for KP879 in 2021.

KP484

Based on our preclinical and clinical data, we believe KP484, if approved by the FDA, may have valuable product features and may provide significant benefits to patients,
physicians, and society when compared to other FDA-approved and widely-prescribed methylphenidate products:

  ● Super-extended release. We believe that this KP484 may provide sustained, consistent effectiveness through the day and into the evening hours.

● Once-daily dosing. PK data from our clinical studies suggest that under fasted conditions, the time to maximum plasma concentration of d-methylphenidate after oral
administration of KP484 is potentially five to seven times longer compared to oral administration of currently marketed IR d-methylphenidate. We believe this extended-
duration attribute of KP484 may allow for convenient, once-daily dosing.

● Amenable to patient-friendly formulations. Our preclinical and clinical data shows that KP484 could ultimately be used in a variety of patient-friendly dosage forms
such  as  oral  thin  film  and  orally  dissolving  tablets  as  a  means  of  increasing  patient  convenience  and  dosage  compliance  by  regularly  and  consistently  taking  the
medications as indicated.

● Composition-of-matter patent protection. KP484 is generally protected by a U.S. composition-of-matter patent that will expire, after utilizing all appropriate patent term
adjustments  but  excluding  possible  term  extensions,  in  2032.  Our  patent  strategy  is  focused  primarily  on  key  geographic  markets,  and  we  have  composition-of-
matter patents generally protecting the major component of KP484 in New Zealand, South Africa and select other countries.

● No generic equivalent product. KP484 contains a prodrug that was given a new chemical name, serdexmethylphenidate, by the USAN, which means that there may be

no generic equivalent product for KP484 in most states, making drug-equivalent substitution potentially difficult at the pharmacy.

KP1077

KP1077 is our prodrug preclinical product candidate for the treatment of IH, an underserved, orphan disease indication. Currently there are no approved drugs in the United
States for IH. We expect to hold a pre-IND meeting with the FDA in 2021.

APADAZ

Overview

In February 2018, we announced that the FDA approved APADAZ for the short-term (no more than 14 days) management of acute pain severe enough to require an opioid
analgesic  and  for  which  alternative  treatments  are  inadequate.  APADAZ  is  an  IR  combination  of  our  prodrug,  benzhydrocodone,  and  acetaminophen,  or  APAP.
Benzhydrocodone was developed with our proprietary LAT technology.

In October 2018, we entered into the APADAZ License Agreement with KVK pursuant to which we have granted an exclusive license to KVK to conduct regulatory activities
for, manufacture and commercialize APADAZ in the United States.

Pursuant to the APADAZ License Agreement, KVK agreed to pay us certain payments and cost reimbursements of an estimated $3.4 million, which includes a payment of
$2.0 million within 10 days of the achievement of a specified milestone related to the initial formulary adoption of APADAZ, or the Initial Adoption Milestone. In addition,
KVK has agreed to make additional payments to us upon the achievement of specified sales milestones of up to $53.0 million in the aggregate. Further, we and KVK will share
the quarterly net profits of APADAZ by KVK in the United States at specified tiered percentages, ranging from us receiving 30% to 50% of net profits, based on the amount of
net sales on a rolling four quarter basis. We are responsible for a portion of commercialization and regulatory expenses for APADAZ until the Initial Adoption Milestone is
achieved, after which KVK will be responsible for all expenses incurred in connection with commercialization and maintaining regulatory approval in the United States.

The APADAZ License Agreement will terminate on the later of the date that all of the patent rights for APADAZ have expired in the United States or KVK’s cessation of
commercialization of APADAZ in the United States. KVK may terminate the APADAZ License Agreement upon 90 days written notice if a regulatory authority in the United
States orders KVK to stop sales of APADAZ due to a safety concern. In addition, after the third anniversary of the APADAZ License Agreement, KVK may terminate the
APADAZ License Agreement without cause upon 18 months prior written notice. We may terminate the APADAZ License Agreement if KVK stops conducting regulatory
activities for or commercializing APADAZ in the United States for a period of six months, subject to specified exceptions, or if KVK or its affiliates challenge the validity,
enforceability or scope of any licensed patent under the APADAZ License Agreement. Both parties may terminate the APADAZ License Agreement (i) upon a material breach
of the APADAZ License Agreement, subject to a 30-day cure period, (ii) the other party encounters bankruptcy or insolvency or (iii) if the Initial Adoption Milestone is not
achieved. Upon termination, all licenses and other rights granted by us to KVK pursuant to the APADAZ License Agreement would revert to us.

The APADAZ License Agreement also established a joint steering committee, which monitors progress of the commercialization of APADAZ.

In November 2019, APADAZ and its authorized generic became nationally available. To date, KVK has utilized targeted non-traditional efforts to build product awareness for
APADAZ as a responsible alternative to currently available hydrocodone/acetaminophen products. For example, in December 2020, KVK began a collaboration with Sure Med
Compliance,  a  provider  of  compliance  and  decision  support  software  designed  to  assist  physicians  in  evaluating  the  appropriateness  of  opioid  treatment,  to  provide  a
patient/provider support program, referred to as Perspectives in Care, to provide education to physicians, pharmacies and patients regarding responsible opioid therapy.  The
Perspectives in Care program was initially launched as a pilot program for APADAZ in Alabama. We may also license the international commercial rights to APADAZ to one
or more collaborators.

Our Intellectual Property

Our intellectual property strategy includes seeking composition-of-matter patents, among other patents, for our prodrugs and product candidates and conjugates of our prodrugs
while also protecting, where appropriate as trade secrets, our proprietary LAT technology, the process by which we identify, screen, evaluate and select ligands to be conjugated
with parent drugs to create our prodrugs. Our current prodrugs all consist of an approved parent drug and one or more ligands that we have selected using our proprietary LAT
technology. The parent drug and ligand or ligands together may potentially constitute a new molecule and thus may be eligible for composition-of-matter patent protection,
among other patent protections, in the United States and abroad.

As of December 31, 2020, we have been granted 48 active patents within the United States, and an additional 78 active foreign patents covering our selected prodrugs and
product candidates. The terms of the 48 issued U.S. patents extend to various dates ranging, for example, between 2030 and 2037. The term of our overall domestic and foreign
patent portfolio related to our selected prodrugs and product candidates, including patent term adjustments but excluding possible patent term extensions, extend to various
dates ranging, for example, between 2030 and 2037, if pending patent applications in each of our patent families issue as patents. As of December 31, 2020, we had 13 pending
patent  applications  under  active  prosecution  in  the  United  States,  and  an  additional  28  pending  foreign  patent  applications  potentially  covering  our  selected  prodrugs  and
product candidates. Our issued and granted patents provide protection in jurisdictions that include the United States, Australia, Canada, Chile, China, European Countries, Hong
Kong, India, Indonesia, Israel, Japan, Kazakhstan, Malaysia, Mexico, New Zealand, Philippines, Romania, Russia, Singapore, South Africa, South Korea, and Vietnam.

We have received composition-of-matter patents and also additionally filed composition-of-matter and method of treatment patent applications related to the AZSTARYS and
KP484 families in the United States and in Argentina, Australia, Brazil, Canada, Chile, China, Egypt, Hong Kong, European Countries, India, Israel, Indonesia, Japan, South
Korea,  Kazakhstan,  Mexico,  Malaysia,  New  Zealand,  Philippines,  Russia,  Singapore,  South  Africa,  Thailand,  Ukraine,  and  Vietnam.  We  anticipate  filing  additional  patent
applications for our prodrugs and product candidates.

Since 2013, the United States Patent and Trademark Office, or the USPTO, has issued 14 composition-of-matter or method of treatment patents covering benzhydrocodone,
which  will  expire,  after  utilizing  all  appropriate  patent  term  adjustments  but  excluding  possible  patent  term  extensions,  no  earlier  than  2030.  Further,  there  are  granted  or
recently  allowed  compositions-of-matter  patents  covering  benzhydrocodone  in  Australia,  Canada,  Chile,  China,  Israel,  Mexico,  South  Africa,  and  South  Korea.  Patent
applications covering benzhydrocodone were pending as of December 31, 2020, in Thailand and Vietnam.

We also depend upon the skills, knowledge and experience of our scientific and technical personnel, as well as that of our advisors, consultants and other contractors. To help
protect  our  LAT  technology,  as  well  as  any  proprietary  know-how  and  show-how  beyond  that  which  is  patentable,  we  rely  on  trade  secret  protection  and  confidentiality
agreements to protect our interests. To this end, we generally require our employees, consultants and advisors to enter into confidentiality agreements prohibiting the disclosure
of confidential information and, in some cases, requiring disclosure and assignment to us of the ideas, developments, discoveries, inventions and improvements important to our
business.

Commercialization

On March 2, 2021, we announced that the FDA approved the NDA for AZSTARYS, a once-daily product for the treatment of ADHD in patients ranging from six years and
older. Corium will lead the commercialization of AZSTARYS per the KP415 License Agreement. Corium expects to make AZSTARYS commercially available in the United
States as early as the second half of 2021.

In February 2018, we announced that the FDA approved APADAZ for the short-term (no more than 14 days) management of acute pain severe enough to require an opioid
analgesic  and  for  which  alternative  treatments  are  inadequate.    In  October  2018,  we  entered  into  the  APADAZ  License  Agreement  with  KVK  pursuant  to  which  we  have
granted an exclusive license to KVK to conduct regulatory activities for, manufacture and commercialize APADAZ in the United States. In November 2019, APADAZ and its
authorized  generic  (AG-APADAZ)  became  nationally  available.  In  December  2020,  KVK,  in  collaboration  with  Sure  Med  Compliance,  initiated  a  regional  launch  of  the
Perspectives in Care program to provide education to physicians, pharmacies and patients regarding responsible opioid therapy and launched a pilot program for APADAZ in
Alabama.

With  the  exception  of  AZSTARYS  and  APADAZ,  commercialization  activities  for  our  product  candidates  in  active  development  have  not  yet  begun.  Because  many  of  our
product candidates may have large potential market opportunities, and may require significant marketing resources, we may conclude that the most appropriate approach to
their commercialization, if they receive regulatory approval, will involve forming a commercial collaboration or strategic relationship similar to those we have entered into with
Commave and KVK, or consummating some type of strategic transaction, with a larger pharmaceutical or other marketing organization. Alternatively, we may conclude that
building our own focused sales and marketing organization will be most appropriate, perhaps as part of a co-promotional arrangement, or some other form of collaboration. As
we get closer to potential approval of our product candidates which are not currently subject to the KP415 License Agreement or the APADAZ License Agreement, we will
work to identify and implement the commercialization strategies that we conclude are the most desirable with regard to the specific product candidates.

Research and Development

Historically, we have devoted a significant amount of resources to develop our product candidates. For the years ended December 31, 2020 and 2019, we recorded $8.8 million
and  $19.4  million,  respectively,  in  research  and  development  expenses.  We  plan  to  devote  a  significant  portion  of  our  capital  towards  research  and  development  for  the
foreseeable  future  as  we  continue  our  efforts  to  further  advance  the  development  of  our  product  candidates.Under  the  KP415  License  Agreement,  Commave  agreed  to  be
responsible  for  and  reimburse  us  for  all  of  development,  commercialization  and  regulatory  expenses  for  the  Licensed  Product  Candidates,  as  defined  in  the  KP415  License
Agreement, subject to certain limitations as set forth in the KP415 License Agreement.  We are responsible for the development costs required to bring Additional Product
Candidates to the successful completion of a Phase 1 proof-of-concept study, or if Commave does not exercise its right of first negotiation at that point, or Commave’s exercise
of its right of first negotiation does not culminate in economic terms which are mutually agreeable between Commave and the Company, any additional development costs
which would be required to pursue the approval of such product candidate.

Competition

Our industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. We will face competition and potential
competition from a number of sources, including pharmaceutical and biotechnology companies, specialty pharmaceutical companies, generic drug companies, drug delivery
companies and academic and research institutions. Our competitors may develop or market drugs that are more effective, more convenient, more widely used and less costly or
have a better safety profile than our products or product candidates and these competitors may also have significantly more resources than us and be more successful than us in
manufacturing and marketing their products.

AZSTARYS  and,  if  approved,  KP484  will  compete  against  currently  marketed,  branded  and  generic  methylphenidate  products  for  the  treatment  of  ADHD.  Some  of  these
currently marketed products include Janssen’s CONCERTA, Tris Pharma’s QUILLIVANT XR and QUILLICHEW ER, Novartis’ RITALIN, FOCALIN and FOCALIN XR,
UCB’s  METADATE  CD,  Noven’s  DAYTRANA,  Neos  Therapeutics’  CONTEMPLA  XR-ODT,  Ironshore  Pharmaceuticals,  Inc.’s  JORNAY  PM  and  Adlon  Therapeutics’
ADHANSIA XR, in addition to multiple other branded and generic methylphenidate products. In addition, AZSTARYS and, if approved, KP484 will face potential competition
from any other methylphenidate products for the treatment of ADHD that are currently in or which may enter into clinical development.

Currently, there are no approved drugs in the United States for the treatment of SUD. If approved, KP879 will face potential competition from any products for the treatment of
SUD that are currently in, or which may enter into, clinical development.

Currently, there are no approved drugs in the United States for the treatment of IH. If approved, KP1077 could face potential competition from any products for the treatment of
IH that are currently in or which may enter into clinical development.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Manufacturing

Our manufacturing strategy is to rely on contract manufacturers to produce our product candidates for clinical trials and, if approved, drug product for commercial sale. We
currently  have  no  manufacturing  facilities  and  limited  personnel  with  manufacturing  experience.  We  rely  on  Johnson  Matthey,  Inc.,  or  JMI,  a  third-party  manufacturer,  to
produce the bulk quantities of benzhydrocodone required to manufacture APADAZ under a supply agreement. We have contracted with another third-party manufacturer to
supply  AZSTARYS  and  KP484  to  be  used  in  our  non-clinical,  clinical  and  formulation  development  programs  necessary  to  support  an  NDA  filing.  We  expect  that  our
commercial  partners  under  the  KP415  License  Agreement  and  the  APADAZ  License  Agreement  will  continue  to  rely  initially  on  these  manufacturers  to  manufacture
commercial quantities of AZSTARYS, KP484 and APADAZ for sale in the United States, following approval by the FDA. We expect to contract with third-party manufacturers
for the manufacture of all API supply needs outside the United States if and when we receive approval by regulatory authorities outside the United States.

Our current and any future third-party manufacturers, their facilities and all lots of drug substance and drug products used in our clinical trials are required to be in compliance
with current good manufacturing practices, or cGMPs. The cGMP regulations include requirements relating to organization of personnel, buildings and facilities, equipment,
control of components and drug product containers and closures, production and process controls, packaging and labeling controls, holding and distribution, laboratory controls,
records and reports, and returned or salvaged products. The manufacturing facilities for our products must meet cGMP requirements and FDA satisfaction before any product is
approved and we can manufacture commercial products. Our current and any future third-party manufacturers are also subject to periodic inspections of facilities by the FDA
and other authorities, including procedures and operations used in the testing and manufacture of our products to assess our compliance with applicable regulations.

Failure to comply with statutory and regulatory requirements subjects a manufacturer to possible legal or regulatory action, including refusal to approve pending applications,
license  suspension  or  revocation,  withdrawal  of  an  approval,  imposition  of  a  clinical  hold  or  termination  of  clinical  trials,  warning  letters,  untitled  letters,  cyber  letters,
modification of promotional materials or labeling, product recalls, product seizures or detentions, refusal to allow imports or exports, total or partial suspension of production or
distribution, debarment, injunctions, fines, consent decrees, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar
agreements to resolve allegations of non-compliance with these laws, refusals of government contracts and new orders under existing contracts, exclusion from participation in
federal and state healthcare programs, restitution, disgorgement or civil or criminal penalties, including fines and individual imprisonments.

Asset Purchase Agreement with Shire

In March 2012, as a result of a litigation settlement, we and our chief executive officer, Travis C. Mickle, Ph. D., entered into an asset purchase agreement with Shire pursuant
to  which  we  sold  assets  and  intellectual  property  to  Shire  for  proceeds  of  $5.1  million.  Pursuant  to  this  agreement,  we  also  granted  Shire  a  right  of  first  refusal  to  acquire,
license or commercialize AZSTARYS and KP484. In January 2019, Shire was acquired by Takeda to whom this right of first refusal was transferred at that time. Takeda did not
exercise this right of first refusal, and therefore we entered into the KP415 License Agreement with Commave.

15

 
 
 
 
 
 
 
 
Third-Party Reimbursement

Sales  of  pharmaceutical  products  depend  in  significant  part  on  the  availability  of  coverage  and  adequate  reimbursement  by  third-party  payors,  such  as  state  and  federal
governmental  authorities,  including  those  that  administer  the  Medicare  and  Medicaid  programs,  and  private  managed  care  organizations  and  health  insurers.  Decisions
regarding the extent of coverage and amount of reimbursement to be provided for each of our product and product candidates will be made on a plan-by-plan basis. One payor’s
determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate reimbursement, for the product. Each third-party
payor determines whether or not it will provide coverage for a drug, what amount it will pay providers for the drug, and on what tier of its formulary the drug will be placed.
These decisions are influenced by the existence of multiple drug products within a therapeutic class and the net cost to the plan, including the amount of the prescription price,
if any, rebated by the drug’s manufacturer. Typically, generic versions of drugs are placed in a preferred tier. The position of a drug on the formulary generally determines
the co-payment that a patient will need to make to obtain the drug and can strongly influence the adoption of a drug by patients and physicians. Patients who are prescribed
treatments for their conditions and providers performing the prescribed services generally rely on third-party payors to reimburse all or part of the associated healthcare costs.
Patients are unlikely to use our products unless coverage is provided, and reimbursement is adequate to cover a significant portion of the cost of our products. Additionally, a
third-party  payor’s  decision  to  provide  coverage  for  a  drug  does  not  imply  that  an  adequate  reimbursement  rate  will  be  approved.  Also,  third-party  payors  are  developing
increasingly sophisticated methods of controlling healthcare costs. As a result, coverage, reimbursement and placement determinations are complex and are often the subject of
extensive negotiations between the payor and the owner of the drug.

Unless we enter into a strategic collaboration under which our collaborator assumes responsibility for seeking coverage and reimbursement for a given product, we will be
responsible for negotiating coverage, reimbursement and placement decisions for our product candidates. Coverage, reimbursement and placement decisions for a new product
are based on many factors including the coverage, reimbursement and placement of already marketed branded drugs for the same or similar indications, the safety and efficacy
of the new product, availability of generics for similar indications, the clinical need for the new product and the cost-effectiveness of the product. Increasingly, both purchasers
and  payors  are  also  conducting  comparative  clinical  and  cost  effectiveness  analyses  involving  application  of  metrics,  including  data  on  patient  outcomes,  provided  by
manufacturers.

Within the Medicare program, as self-administered drugs, our product and product candidates would be reimbursed under the expanded prescription drug benefit known as
Medicare Part D. This program is a voluntary Medicare benefit administered by private plans that operate under contracts with the federal government. These plans develop
formularies that determine which products are covered and what co-pay will apply to covered drugs. The plans have considerable discretion in establishing formularies and
tiered co-pay structures, negotiating rebates with manufacturers and placing prior authorization and other restrictions on the utilization of specific products, subject to review by
the Centers for Medicare & Medicaid Services, or CMS, for discriminatory practices. These Part D plans negotiate discounts with drug manufacturers, which are passed on, in
whole or in part, to each of the plan’s enrollees through reduced premiums. Historically, Part D beneficiaries have been exposed to significant out-of-pocket costs after they
surpass an annual coverage limit and until they reach a catastrophic coverage threshold. However, changes made by recent legislation will reduce this patient coverage gap,
known  as  the  “donut  hole”,  by  transitioning  patient  responsibility  in  that  coverage  range  from  100%  in  2010  to  only  25%  currently.  To  help  achieve  this  reduction,
pharmaceutical manufacturers are required to provide quarterly discounts of 70%, which commenced January 1, 2019. In 2020, drug manufacturers became be responsible for a
larger share of total drug costs due to an increase to the catastrophic threshold. Such increase will also result in a higher out-of-pocket threshold paid by Part D beneficiaries.

If  a  drug  product  is  available  for  reimbursement  by  Medicare  or  Medicaid,  its  manufacturer  must  comply  with  various  health  regulatory  requirements  and  price  reporting
metrics, which may include, as applicable, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, the Medicaid rebate requirements of the Omnibus
Budget Reconciliation Act of 1990, or the OBRA, and the Veterans Health Care Act of 1992, or the VHCA, each as amended. Among other things, the OBRA requires drug
manufacturers with certain drugs covered by Medicaid to pay rebates on prescription drugs to state Medicaid programs. States may also negotiate “supplemental” Medicaid
rebates on drug products dispensed under Medicaid. Manufacturers participating in Medicaid are also generally required to participate in the Public Health Service 340B Drug
Discount Program, which imposes a mandatory discount on purchases by certain customers. Manufacturers of innovator drugs, including 505(b)(2) drugs, that participate in the
Medicaid  program  are  also  required  to  offer  the  drugs  on  the  Federal  Supply  Schedule  purchasing  program  of  the  General  Services  Administration  for  purchase  by  the
Department of Veterans Affairs, the Department of Defense and other authorized users at a mandatory discount. Additional laws and requirements apply to these contracts.
Participation in such federal programs may result in prices for our future products that will likely be lower than the prices we might otherwise obtain.

Third-party payors, including the U.S. government, continue to apply downward pressure on the reimbursement of pharmaceutical products. Also, the trend towards managed
health care in the United States and the concurrent growth of organizations such as health maintenance organizations may result in lower reimbursement for pharmaceutical
products. We expect that these trends will continue as these payors implement various proposals or regulatory policies, including various provisions of the recent health reform
legislation that affect reimbursement of these products. There are currently, and we expect that there will continue to be, a number of federal and state proposals to implement
controls on reimbursement and pricing, directly and indirectly.

Government Regulation

The  FDA  and  comparable  regulatory  agencies  in  state  and  local  jurisdictions  and  in  foreign  countries  impose  substantial  requirements  upon  the  clinical  development,
manufacture and marketing of pharmaceutical products. These agencies and other federal, state and local entities regulate research and development activities and the testing,
manufacture, quality control, safety, effectiveness, labeling, storage, packaging, recordkeeping, tracking, approval, import, export, distribution, advertising and promotion of our
products.

The process required by the FDA before product candidates may be marketed in the United States generally involves the following:

  ● non-clinical laboratory and animal tests that must be conducted in accordance with good laboratory practices, or GLPs;

  ● submission of an investigational new drug application, or IND, which must be received by the FDA and become effective before human clinical trials may begin;

  ● approval by an independent institutional review board, or IRB, for each clinical site or centrally before each trial may be initiated;

● adequate and well-controlled human clinical trials to establish the safety and efficacy of the proposed product candidate for its intended use, performed in accordance

with good clinical practices, or GCPs;

  ● submission of a NDA to the FDA;

  ● satisfactory completion of an FDA advisory committee review, if applicable;

  ● pre-approval inspection of manufacturing facilities and selected clinical investigators for their compliance with cGMP and GCPs; and

  ● FDA approval of an NDA to permit commercial marketing for particular indications for use.

Prior to the commencement of marketing of controlled substances, the DEA must also determine the controlled substance schedule, taking into account the recommendation of
the FDA.

The  testing  and  approval  process  requires  substantial  time,  effort  and  financial  resources.  Preclinical  studies  include  laboratory  evaluation  of  drug  substance  chemistry,
pharmacology, toxicity and drug product formulation, as well as animal studies to assess potential safety and efficacy. Prior to commencing the first human clinical trial with a
product  candidate,  we  must  submit  the  results  of  the  preclinical  tests  and  preclinical  literature,  together  with  manufacturing  information,  analytical  data  and  any  available
clinical data or literature, among other things, to the FDA as part of an IND. Additional non-clinical studies may be required even after the IND is submitted.

The  IND  becomes  effective  30  days  after  receipt  by  the  FDA,  unless  the  FDA,  within  the  30-day  time  period,  raises  safety  concerns  or  questions  about  the  conduct  of  the
clinical trial by imposing a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Submission of
an IND may not result in FDA authorization to commence a clinical trial. A separate submission to the existing IND must be made for each successive clinical trial conducted
during product development, as well as amendments to previously submitted clinical trials. Further, an independent IRB for each study site proposing to conduct the clinical
trial must review and approve the plan for any clinical trial, its informed consent form and other communications to study subjects before the clinical trial commences at that
site. The IRB must continue to oversee the clinical trial while it is being conducted, including any changes to the study plans. Regulatory authorities, an IRB or the sponsor may
suspend or discontinue a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk, the clinical trial is
not being conducted in accordance with the FDA’s or the IRB’s requirements, if the drug has been associated with unexpected serious harm to subjects, or based on evolving
business objectives or competitive climate. Some studies also include a data safety monitoring board, which receives special access to unblinded data during the clinical trial
and may advise us to halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy.

In general, for purposes of NDA approval, human clinical trials are typically conducted in three sequential phases that may overlap.

● Phase  1-Studies  are  initially  conducted  to  test  the  product  candidate  for  safety,  dosage  tolerance,  structure-activity  relationships,  mechanism  of  action,  absorption,
metabolism, distribution and excretion in healthy volunteers or subjects with the target disease or condition. If possible, Phase 1 trials may also be used to gain an initial
indication of product effectiveness.

● Phase 2-Controlled  studies  are  conducted  with  groups  of  subjects  with  a  specified  disease  or  condition  to  provide  enough  data  to  evaluate  the  preliminary  efficacy,
optimal dosages and dosing schedule and expanded evidence of safety. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger
and more expensive Phase 3 clinical trials.

● Phase 3-These clinical trials are undertaken in larger subject populations to provide statistically significant evidence of clinical efficacy and to further test for safety in
an expanded subject population at multiple clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the product and provide an
adequate  basis  for  product  labeling.  These  trials  may  be  done  globally  to  support  global  registrations  so  long  as  the  global  sites  are  also  representative  of  the  U.S.
population and the conduct of the study at global sites comports with FDA regulations and guidance, such as compliance with GCPs.

In  the  case  of  a  505(b)(2)  NDA,  some  of  the  above-described  studies  and  preclinical  studies  may  not  be  required  or  may  be  abbreviated.  Bridging  studies  may  be  needed,
however, to demonstrate the relevance of the studies that were previously conducted by other sponsors to the drug that is the subject of the NDA.

The FDA may require, or companies may pursue, additional clinical trials after a product is approved. These so-called Phase 4, or post-market, studies may be made a condition
to be satisfied after approval. The results of Phase 4 studies can confirm the effectiveness of a product candidate and can provide important safety information.

Clinical  trials  must  be  conducted  under  the  supervision  of  qualified  investigators  in  accordance  with  GCP  requirements,  which  includes  the  requirements  that  all  research
subjects  provide  their  informed  consent  in  writing  for  their  participation  in  any  clinical  trial,  and  the  review  and  approval  of  the  study  by  an  IRB.  Investigators  must  also
provide  information  to  the  clinical  trial  sponsors  to  allow  the  sponsors  to  make  specified  financial  disclosures  to  the  FDA.  Clinical  trials  are  conducted  under  protocols
detailing,  among  other  things,  the  objectives  of  the  trial,  the  trial  procedures,  the  parameters  to  be  used  in  monitoring  safety  and  the  efficacy  criteria  to  be  evaluated  and  a
statistical analysis plan. Information about some clinical trials, including a description of the trial and trial results, must be submitted within specific timeframes to the National
Institutes of Health, or NIH, for public dissemination on their ClinicalTrials.gov website.

The manufacture of investigational drugs for the conduct of human clinical trials is subject to cGMP requirements. Investigational drugs and active pharmaceutical ingredients
imported into the United States are also subject to regulation by the FDA relating to their labeling and distribution. Further, the export of investigational drug products outside
of the United States is subject to regulatory requirements of the receiving country as well as U.S. export requirements under the FFDCA. Progress reports detailing the results of
the clinical trials must be submitted at least annually to the FDA and the IRB and more frequently if serious adverse events occur.

Concurrent  with  clinical  trials,  companies  usually  complete  additional  animal  studies  and  must  also  develop  additional  information  about  the  chemistry  and  physical
characteristics  of  the  product  candidate  as  well  as  finalize  a  process  for  manufacturing  the  product  in  commercial  quantities  in  accordance  with  cGMP  requirements.  The
manufacturing  process  must  be  capable  of  consistently  producing  quality  batches  of  the  product  candidate  and,  among  other  things,  must  develop  methods  for  testing  the
identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate
that the product candidate does not undergo unacceptable deterioration over its shelf life.

505(b)(2) Approval Process

Section  505(b)(2)  of  the  FFDCA,  provides  an  alternate  regulatory  pathway  to  FDA  approval  for  new  or  improved  formulations  or  new  uses  of  previously  approved  drug
products. Specifically, 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comes from studies not conducted by or for the
applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom the investigations were conducted. The applicant may rely
upon the FDA’s prior findings of safety and effectiveness for an approved product that acts as the reference listed drug for purposes of a 505(b)(2) NDA. The FDA may also
require 505(b)(2) applicants to perform additional studies or measurements to support any changes from the reference listed drug. The FDA may then approve the new product
candidate 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.

Our current and anticipated product candidates are or will be based on already approved APIs in combination with a ligand. Accordingly, we have and expect to be able to
continue to rely on information from studies previously conducted by the companies that obtained approval for drugs containing such APIs.

Orange Book Listing

Section  505  of  the  FFDCA  describes  three  types  of  marketing  applications  that  may  be  submitted  to  the  FDA  to  request  marketing  authorization  for  a  new  drug.  A
Section  505(b)(1)  NDA  is  an  application  that  contains  full  reports  of  investigations  of  safety  and  efficacy.  A  505(b)(2)  NDA  is  an  application  that  contains  full  reports  of
investigations of safety and efficacy but where at least some of the information required for approval comes from investigations that were not conducted by or for the applicant
and for which the applicant has not obtained a right of reference or use from the person by or for whom the investigations were conducted. This regulatory pathway enables the
applicant  to  rely,  in  part,  on  the  FDA’s  prior  findings  of  safety  and  efficacy  for  an  existing  product,  or  published  literature,  in  support  of  its  application.  Section  505(j)
establishes an abbreviated approval process for a generic version of approved drug products through the submission of an abbreviated new drug application, or ANDA. An
ANDA  provides  for  marketing  of  a  generic  drug  product  that  has  the  same  active  ingredients,  dosage  form,  strength,  route  of  administration,  labeling,  performance
characteristics and intended use, among other things, to a previously approved product. ANDAs are termed “abbreviated” because they are generally not required to include
preclinical and clinical data to establish safety and efficacy. Instead, generic applicants must scientifically demonstrate that their product is bioequivalent to, or performs in the
same  manner  as,  the  innovator  drug  through  in  vitro,  in  vivo,  or  other  testing.  The  generic  version  must  deliver  the  same  amount  of  active  ingredients  into  a  subject’s
bloodstream in the same amount of time as the innovator drug and can often be substituted by pharmacists under prescriptions written for the reference listed drug.

In seeking approval for a drug through an NDA, including a 505(b)(2) NDA, applicants are required to list with the FDA patents whose claims cover the applicant’s product.
Upon approval of an NDA, each of the patents listed in the application for the drug is then published in the Orange Book. These products may be cited by potential competitors
in support of approval of an ANDA or 505(b)(2) NDA.

Any applicant who files an ANDA seeking approval of a generic equivalent version of a drug listed in the Orange Book or a 505(b)(2) NDA referencing a drug listed in the
Orange Book must certify to the FDA that (1) no patent information on the drug or method of use that is the subject of the application has been submitted to the FDA; (2) such
patent has expired; (3) the date on which such patent expires; or (4) such patent is invalid or will not be infringed upon by the manufacture, use or sale of the drug product for
which the application is submitted. This last certification is known as a Paragraph IV certification. Generally, the ANDA or 505(b)(2) NDA cannot be approved until all listed
patents have expired, except where the ANDA or 505(b)(2) NDA applicant challenges a listed patent through a Paragraph IV certification. If the applicant does not challenge
the listed patents or does not indicate that it is not seeking approval of a patented method of use, the ANDA or 505(b)(2) NDA application will not be approved until all of the
listed patents claiming the referenced product have expired, or, if permissible, are carved out.

If the ANDA or 505(b)(2) NDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the
holder of the NDA for the reference listed drug and the patent owner once the application has been accepted for filing by the FDA. The NDA holder or patent owner 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 prevents the FDA from approving the application until the earlier of 30 months from the date of the lawsuit, expiration of the patent, settlement of the
lawsuit, a decision in the infringement case that is favorable to the applicant or such shorter or longer period as may be ordered by a court. This prohibition is generally referred
to as the 30-month stay. In instances where an ANDA or 505(b)(2) NDA applicant files a Paragraph IV certification, the NDA holder or patent owner regularly take action to
trigger the 30-month stay, recognizing that the related patent litigation may take many months or years to resolve. 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
applicant may also elect to submit a statement certifying that its proposed label does not contain, or carves out, any language regarding the patented method-of-use rather than
certify to a listed method-of-use patent.

Exclusivity

The  FDA  provides  periods  of  regulatory  exclusivity,  which  provides  the  holder  of  an  approved  NDA  limited  protection  from  new  competition  in  the  marketplace  for  the
innovation  represented  by  its  approved  drug  for  a  period  of  three  or  five  years  following  the  FDA’s  approval  of  the  NDA.  Five  years  of  exclusivity  are  available  to  new
chemical entities, or NCEs. An NCE is a drug that contains no active moiety that has been approved by the FDA in any other NDA. An active moiety is the molecule or ion,
excluding  those  appended  portions  of  the  molecule  that  cause  the  drug  to  be  an  ester,  salt,  including  a  salt  with  hydrogen  or  coordination  bonds,  or  other  noncovalent
derivatives, such as a complex, chelate, or clathrate, of the molecule, responsible for the therapeutic activity of the drug substance. During the exclusivity period, the FDA may
not accept for review or approve an ANDA or a 505(b)(2) NDA submitted by another company that contains the previously approved active moiety. An ANDA or 505(b)(2)
application, however, may be submitted one year before NCE exclusivity expires if a Paragraph IV certification is filed. Applicants may also seek to carve out certain drug
labeling that is protected by exclusivity.

If a product is not eligible for the NCE exclusivity, it may be eligible for three years of exclusivity. Three-year exclusivity is available to the holder of an NDA, including a
505(b)(2) NDA, for a particular condition of approval, or change to a marketed product, such as a new formulation for a previously approved product, if one or more new
clinical trials, other than bioavailability or bioequivalence trials, was essential to the approval of the application and was conducted or sponsored by the applicant. This three-
year exclusivity period protects against FDA approval of ANDAs and 505(b)(2) NDAs for the condition of the new drug’s approval. As a general matter, three-year exclusivity
does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs for generic versions of the original, unmodified drug product. Five-year and three-year exclusivity will
not delay the submission or approval of a full NDA; however, an applicant submitting a full 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 efficacy.

NDA Submission and Review by the FDA

Assuming successful completion of the required clinical and preclinical testing, among other items, the results of product development, including chemistry, manufacture and
controls, non-clinical studies and clinical trials are submitted to the FDA, along with proposed labeling, as part of an NDA. The submission of an NDA requires payment of a
substantial application user fee to the FDA. These user fees must be filed at the time of the first submission of the application, even if the application is being submitted on a
rolling basis. Fee waivers or reductions are available in some circumstances.

In addition, under the Pediatric Research Equity Act, or PREA, an NDA or supplement to an NDA for a new active ingredient, indication, dosage form, dosage regimen or route
of administration must contain data that are adequate to assess the safety and efficacy of the drug for the claimed indications in all relevant pediatric subpopulations, and to
support  dosing  and  administration  for  each  pediatric  subpopulation  for  which  the  product  is  safe  and  effective.  The  FDA  may,  on  its  own  initiative  or  at  the  request  of  the
applicant,  grant  deferrals  for  submission  of  some  or  all  pediatric  data  until  after  approval  of  the  product  for  use  in  adults  or  full  or  partial  waivers  from  the  pediatric  data
requirements.

The FDA may refer drugs which present difficult questions of safety, purity or potency to an advisory committee. An advisory committee is a panel that typically includes
clinicians and other experts who review, evaluate and make a recommendation as to whether the application should be approved and under what conditions. The FDA is not
bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

The  FDA  reviews  applications  to  determine,  among  other  things,  whether  a  product  is  safe  and  effective  for  its  intended  use  and  whether  the  manufacturing  controls  are
adequate to assure and preserve the product’s identity, strength, quality and purity. Before approving an NDA, the FDA will inspect the facility or facilities where the product is
manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities, including contract manufacturers and subcontracts,
are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA,
the FDA will typically inspect one or more clinical trial sites to assure compliance with GCPs.

Once  the  FDA  receives  an  application,  it  has  60  days  to  review  the  NDA  to  determine  if  it  is  substantially  complete  to  permit  a  substantive  review,  before  it  accepts  the
application for filing. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. The timeline for the FDA to complete its review of a NDA
may differ based on whether the application is a standard review or priority review application. The FDA may give a priority review designation to drugs that are intended to
treat serious conditions and provide significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions. Under the goals and
policies agreed to by the FDA under the Prescription Drug User Fee Act, or PDUFA, the FDA has set the review goal of ten months from the 60-day filing date to complete its
initial review of a standard NDA for a new molecular entity, or NME, and make a decision on the application. For non-NME standard applications, the FDA has set the review
goal of ten months from the submission date to complete its initial review and to make a decision on the application. For priority review applications, the FDA has set the
review goal of reviewing NME NDAs within six months of the 60-day filing date and non-NME applications within six months of the submission date. Such deadlines are
referred to as the PDUFA date. The PDUFA date is only a goal and the FDA does not always meet its PDUFA dates. The review process and the PDUFA date may also be
extended if the FDA requests or the NDA sponsor otherwise provides additional information or clarification regarding the submission.

Once the FDA’s review of the application is complete, the FDA will issue either a Complete Response Letter, or CRL, or approval letter. A CRL indicates that the review cycle
of the application is complete, and the application is not ready for approval. A CRL generally contains a statement of specific conditions that must be met in order to secure
final approval of the NDA and may require additional clinical or preclinical testing, or other information or analyses in order for the FDA to reconsider the application. The
FDA  has  the  goal  of  reviewing  90%  of  application  resubmissions  in  either  two  or  six  months  of  the  resubmission  date,  depending  on  the  kind  of  resubmission  (Class  1  or
Class 2). Even with the submission of additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. If and
when those conditions have been met to the FDA’s satisfaction, the FDA may issue an approval letter. An approval letter authorizes commercial marketing of the drug with
specific prescribing information for specific indications.

The FDA may delay or refuse approval of an NDA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing
testing and surveillance to monitor safety or efficacy of a product, or impose other conditions, including distribution restrictions or other risk management mechanisms. For
example, the FDA may require a risk evaluation and mitigation strategy, or REMS, as a condition of approval or following approval to mitigate any identified or suspected
serious risks and ensure safe use of the drug. The FDA may prevent or limit further marketing of a product, or impose additional post-marketing requirements, based on the
results  of  post-marketing  studies  or  surveillance  programs.  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 testing requirements, FDA notification and FDA review and approval. Further, should new safety information
arise, additional testing, product labeling or FDA notification may be required.

If  regulatory  approval  of  a  product  is  granted,  such  approval  may  entail  limitations  on  the  indicated  uses  for  which  such  product  may  be  marketed  or  may  include
contraindications, warnings or precautions in the product labeling, including a boxed warning. If the FDA requires a boxed warning, we would also be subject to specified
promotional  restrictions,  such  as  the  prohibition  of  reminder  advertisements.  The  FDA  also  may  not  approve  the  inclusion  of  labeling  claims  necessary  for  successful
marketing. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing regulatory standards is not maintained or if problems occur
after the product reaches the marketplace. In addition, the FDA may require Phase 4 post-marketing studies to monitor the effect of approved products and may limit further
marketing of the product based on the results of these post-marketing studies.

20

 
 
 
 
 
 
 
 
 
 
 
Post-approval Requirements

Any  products  manufactured  or  distributed  by  us  pursuant  to  FDA  approvals  are  subject  to  continuing  regulation  by  the  FDA,  including  manufacturing,  periodic  reporting,
product sampling and distribution, advertising, promotion, drug shortage reporting, compliance with any post-approval requirements imposed as a conditional of approval such
as Phase 4 clinical trials, REMS and surveillance, recordkeeping and reporting requirements, including adverse experiences.

After approval, most changes to the approved product, such as adding new indications or other labeling claims are subject to prior FDA review and approval. There also are
continuing,  annual  human  prescription  drug  program  fee  requirements  for  approved  products.  Drug  manufacturers  and  their  subcontractors  are  required  to  register  their
establishments with the FDA and certain state agencies and to list their drug products, and are subject to periodic announced and unannounced inspections by the FDA and
these state agencies for compliance with cGMPs and other requirements, which impose procedural and documentation requirements upon us and our third-party manufacturers.
We cannot be certain that we or our present or future suppliers will be able to comply with the cGMP regulations and other FDA regulatory requirements.

Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented, or FDA notification. FDA regulations also require
investigation  and  correction  of  any  deviations  from  cGMPs  and  specifications  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.

Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to
comply with regulatory requirements, may result in withdrawal of marketing approval, mandatory revisions to the approved labeling to add new safety information or other
limitations, imposition of post-market studies or clinical trials to assess new safety risks, or imposition of distribution or other restrictions under a REMS program, among other
consequences.

The FDA closely regulates the marketing and promotion of drugs. A company can make only those claims relating to safety and efficacy, purity and potency that are approved
by the FDA. Physicians, in their independent professional medical judgment, may prescribe legally available products for uses that are not described in the product’s labeling
and that differ from those tested by us and approved by the FDA. We, however, are prohibited from marketing or promoting drugs for uses outside of the approved labeling.

In  addition,  the  distribution  of  prescription  pharmaceutical  products,  including  samples,  is  subject  to  the  Prescription  Drug  Marketing  Act,  or  PDMA,  which  regulates  the
distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors by the states. Both the PDMA and
state  laws  limit  the  distribution  of  prescription  pharmaceutical  product  samples  and  impose  requirements  to  ensure  accountability  in  distribution.  The  Drug  Supply  Chain
Security Act also imposes obligations on manufacturers of pharmaceutical products related to product tracking and tracing.

Failure to comply with any of the FDA’s requirements could result in significant adverse enforcement actions. These include a variety of administrative or judicial sanctions,
such  as  refusal  to  approve  pending  applications,  license  suspension  or  revocation,  withdrawal  of  an  approval,  imposition  of  a  clinical  hold  or  termination  of  clinical  trials,
warning  letters,  untitled  letters,  cyber  letters,  modification  of  promotional  materials  or  labeling,  product  recalls,  product  seizures  or  detentions,  refusal  to  allow  imports  or
exports, total or partial suspension of production or distribution, debarment, injunctions, fines, consent decrees, 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, refusals of government contracts and new orders under
existing contracts, exclusion from participation in federal and state healthcare programs, restitution, disgorgement or civil or criminal penalties, including fines and individual
imprisonment. Any of these sanctions could result in adverse publicity, among other adverse consequences.

Risk Evaluation and Mitigation Strategy

The FDA has the authority to require a REMS to ensure the safe use of the drug. In determining whether a REMS is necessary, the FDA must consider the size of the population
likely to use the drug, the seriousness of the disease or condition to be treated, the expected benefit of the drug, the duration of treatment, the seriousness of known or potential
adverse events, and whether the drug is a new molecule. If the FDA determines a REMS is necessary, the drug sponsor must develop the REMS program, which the FDA
reviews and approves. A REMS may be required for a single drug or an entire class of drugs.

A REMS may be required to include various elements, including, but not limited to, a medication guide or patient package insert, a communication plan to educate healthcare
providers of the drug’s risks, limitations on who may prescribe or dispense the drug, elements to assure safe use, or ETASU, an implementation system, or other measures that
the FDA deems necessary to assure the safe use of the drug. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing
only under specified circumstances, special monitoring, and the use of patient registries. In addition, the REMS must include a timetable to periodically assess the strategy. The
FDA may also impose a REMS requirement on a drug already on the market if the FDA determines, based on new safety information, that a REMS is necessary to ensure that
the drug’s benefits outweigh its risks. The requirement for a REMS can materially affect the potential market and profitability of a drug.

APADAZ is currently subject to a REMS requirement, and under the APADAZ License Agreement, KVK is responsible for the maintenance of and all expenses and fees for
the APADAZ REMS program.

DEA Regulation

Most of our products and product candidates, if approved, will be regulated as “controlled substances” as defined in the Controlled Substances Act of 1970, or CSA, and the
DEA’s  implementing  regulations,  which  establish  registration,  security,  recordkeeping,  reporting,  storage,  distribution,  importation,  exportation,  inventory,  quota  and  other
requirements administered by the DEA. These requirements are directly applicable to us and also applicable to our contract manufacturers and to distributors, prescribers and
dispensers of our product candidates. The DEA regulates the handling of controlled substances through a closed chain of distribution. This control extends to the equipment and
raw materials used in their manufacture and packaging in order to prevent loss and diversion into illicit channels of commerce.

The  DEA  regulates  controlled  substances  as  Schedule  I,  II,  III,  IV  or  V  substances.  Schedule  I  substances  by  definition  have  no  established  medicinal  use  and  may  not  be
marketed or sold in the United States. A pharmaceutical product may be listed as Schedule II, III, IV or V, with Schedule II substances considered to present the highest risk of
abuse and Schedule V substances the lowest relative risk of abuse among such substances. Schedule II drugs are those that meet the following criteria:

  ● the drug has a high potential for abuse;

  ● the drug has a currently accepted medical use in treatment in the United States or a currently accepted medical use with severe restrictions; and

  ● abuse of the drug may lead to severe psychological or physical dependence.

APADAZ is, and the FDA has recommended that AZSTARYS should be, listed as a Schedule II controlled substance under the CSA, and we expect that our other products and
product candidates may be listed in the same manner, if approved. If our product candidates are ultimately listed as Schedule II controlled substances, then the importation of
APIs  for  our  product  candidates,  as  well  as  the  manufacture,  shipping,  storage,  sales  and  use  of  the  products,  will  be  subject  to  a  high  degree  of  regulation.  In  addition  to
maintaining an importer and/or exporter registration, importers and exporters of controlled substances must obtain a permit for every import of a Schedule I or II substance and
a narcotic substance in Schedule III, IV and V, as well as every export of a Schedule I or II substance and a narcotic substance in Schedule III and IV. For all other drugs in
Schedule III, IV and V, importers and exporters must submit an import or export declaration. Schedule II drugs are subject to the strictest requirements for registration, security,
recordkeeping  and  reporting.  Also,  distribution  and  dispensing  of  these  drugs  are  highly  regulated.  For  example,  all  Schedule  II  drug  prescriptions  must  be  signed  by  a
physician, physically presented to a pharmacist and may not be refilled without a new prescription. Electronic prescriptions may also be permissible depending on the state, so
long as the prescription complies with the DEA’s requirements for electronic prescriptions.

Controlled substances classified in Schedule III, IV, and V are also subject to registration, recordkeeping, reporting, and security requirements. For example, Schedule III drug
prescriptions must be authorized by a physician and may not be refilled more than six months after the date of the original prescription or more than five times. A prescription
for  controlled  substances  classified  in  Schedules  III,  IV,  and  V  issued  by  a  physician,  may  be  communicated  either  orally,  in  writing  or  by  facsimile  to  the  pharmacies.
Controlled  substances  that  are  also  classified  as  narcotics,  such  as  hydrocodone,  oxycodone  and  hydromorphone,  are  also  subject  to  additional  DEA  requirements,  such  as
manufacturer reporting of the import of narcotic raw material.

Annual registration is required for any facility that manufactures, distributes, dispenses, imports or exports any controlled substance. The registration is specific to the particular
location,  activity  and  controlled  substance  schedule.  For  example,  separate  registrations  are  needed  for  import  and  manufacturing,  and  each  registration  will  specify  which
schedules of controlled substances are authorized. Similarly, separate registrations are also required for separate facilities. Acquisition and distribution transactions must also be
reported for Schedule I and II controlled substances, as well as Schedule III narcotic substances.

The DEA typically inspects a facility to review its security measures prior to issuing a registration and on a periodic basis. Security requirements vary by controlled substance
schedule, with the most stringent requirements applying to Schedule I and Schedule II substances. Required security measures include background checks on employees and
physical control of inventory through measures such as cages, surveillance cameras and inventory reconciliations. Records must be maintained for the handling of all controlled
substances, and periodic reports made to the DEA, for example distribution reports for Schedule I and II controlled substances, Schedule III substances that are narcotics, and
other designated substances. Reports must also be made for thefts or losses of any controlled substance, and to obtain authorization to destroy any controlled substance. In
addition, special permits and notification requirements apply to imports and exports of narcotic drugs. To enforce these requirements, the DEA conducts periodic inspections of
registered establishments that handle controlled substances. Failure to maintain compliance with applicable requirements, particularly as manifested in loss or diversion, can
result in administrative, civil or criminal enforcement action that could have a material adverse effect on our business, results of operations and financial condition. The DEA
may seek civil penalties, refuse to renew necessary registrations, or initiate administrative proceedings to revoke those registrations. In some circumstances, violations could
result in criminal proceedings.

In addition, a DEA quota system controls and limits the availability and production of controlled substances in Schedule I or II. Distributions of any Schedule I or II controlled
substance or Schedule III narcotic must also be accompanied by special order forms, with copies provided to the DEA. Because AZSTARYS, APADAZ and our other current
product candidates currently under development may be regulated as Schedule II controlled substances, they may be subject to the DEA’s production and procurement quota
scheme. The DEA establishes annually an aggregate quota for how much of a controlled substance may be produced in total in the United States based on the DEA’s estimate of
the quantity needed to meet legitimate scientific and medicinal needs. The limited aggregate amount of stimulants that the DEA allows to be produced in the United States each
year is allocated among individual companies, which must submit applications annually to the DEA for individual production and procurement quotas. We and our contract
manufacturers must receive an annual quota from the DEA in order to produce or procure any Schedule I or Schedule II substances for use in manufacturing of our product
candidates.  The  DEA  may  adjust  aggregate  production  quotas  and  individual  production  and  procurement  quotas  from  time  to  time  during  the  year,  although  the  DEA  has
substantial discretion in whether or not to make such adjustments. Our, or our contract manufacturers’, quota of an active ingredient may not be sufficient to meet commercial
demand or complete clinical trials. Any delay, limitation or refusal by the DEA in establishing our, or our contract manufacturers’, quota for controlled substances could delay
or stop our clinical trials or product launches, which could have a material adverse effect on our business, financial position and results of operations.

Individual  states  also  independently  regulate  controlled  substances.  We  and  our  contract  manufacturers  will  be  subject  to  state  regulation  on  distribution  of  these  products,
including, for example, state requirements for licensures or registration.

Other Healthcare and Privacy Regulatory Frameworks

Our  business  activities,  including  but  not  limited  to,  research,  sales,  promotion,  distribution,  medical  education  and  other  activities  are  subject  to  regulation  by  numerous
regulatory and law enforcement authorities in the United States in addition to the FDA, including potentially the Department of Justice, the U.S. Department of Health and
Human Services and its various divisions, including the CMS and the Health Resources and Services Administration, the Department of Veterans Affairs, the Department of
Defense and state and local governments. Our business activities must comply with numerous healthcare laws as well as privacy and information security laws, including those
described below. Compliance with government regulations requires the expenditure of substantial time and financial resources.

The federal Anti-Kickback Statute prohibits, among other things, any person or entity, from knowingly and willfully offering, paying, soliciting or receiving any remuneration,
directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward, or in return for, the referral of an individual for, or purchasing, leasing, ordering, or arranging
for the purchase, lease or order of, any good, facility, item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term remuneration has
been  interpreted  broadly  to  include  anything  of  value.  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 and practices that involve remuneration that may be alleged to be intended to induce prescribing, purchasing
or recommending 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 federal 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 of its facts and circumstances. Additionally, the Patient Protection and Affordable Care Act, as amended by the
Health  Care  and  Education  Reconciliation  Act  of  2010,  or  collectively,  the  ACA,  amended  the  intent  requirement  of  the  federal  Anti-Kickback  Statute,  and  some  other
healthcare criminal fraud statutes, so that a person or entity no longer needs to have actual knowledge of the federal Anti-Kickback Statute, or the specific intent to violate it, to
have violated those statutes. The ACA also provided that a violation of the federal Anti-Kickback Statute is grounds for the government or a whistleblower to assert that a claim
for payment of items or services resulting from such violation constitutes a false or fraudulent claim for purposes of the False Claims Act.

The  federal  civil  and  criminal  false  claims  laws,  including  the  federal  False  Claims  Act,  which  can  be  enforced  by  private  citizens  through  civil  whistleblower  or  qui
tam actions, prohibit, among other things, any person or entity from knowingly presenting, or causing to be presented, a false claim for payment to, or approval by, the federal
government,  including  the  Medicare  and  Medicaid  programs,  or  knowingly  making,  using,  or  causing  to  be  made  or  used  a  false  record  or  statement  material  to  a  false  or
fraudulent claim or to avoid, decrease or conceal an obligation to pay money to the federal government.

The civil monetary penalties statute imposes penalties against any person or entity who, 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.

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal criminal statutes that prohibit knowingly and willfully executing,
or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations or promises, any of the money
or  property  owned  by,  or  under  the  custody  or  control  of,  any  healthcare  benefit  program,  regardless  of  whether  the  payor  is  public  or  private,  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  by  any  trick  or  device  a  material  fact  or  making  any  materially  false  statements  in  connection  with  the  delivery  of,  or  payment  for,  healthcare
benefits,  items  or  services  relating  to  healthcare  matters.  Additionally,  the  ACA  amended  the  intent  requirement  of  some  of  these  criminal  statutes  under  HIPAA  so  that  a
person or entity no longer needs to have actual knowledge of the statute, or the specific intent to violate it, to have committed a violation.

Additionally, the federal Open Payments program, created under Section 6002 of the ACA and its implementing regulations, require some manufacturers of drugs, devices,
biologicals and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with specified exceptions) to report
annually  information  related  to  specified  payments  or  other  transfers  of  value  provided  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and
chiropractors)  and  teaching  hospitals,  or  to  entities  or  individuals  at  the  request  of,  or  designated  on  behalf  of,  the  physicians  and  teaching  hospitals  and  to  report  annually
specified 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.

In  addition,  we  may  be  subject  to  data  privacy  and  security  regulation  by  foreign,  federal,  state  and  local  governments.  HIPAA,  as  amended  by  the  Health  Information
Technology  for  Economic  and  Clinical  Health  Act,  or  HITECH,  and  its  implementing  regulations,  imposes  requirements  on  covered  entities,  including  certain  healthcare
providers,  health  plans  and  healthcare  clearinghouses,  and  their  respective  business  associates,  independent  contractors  or  agents  of  covered  entities  that  receive  or  obtain
individually  identifiable  health  information  in  connection  with  providing  a  service  on  behalf  of  a  covered  entity,  and  their  covered  subcontractors,  relating  to  the  privacy,
security and transmission of individually identifiable health information. Among other things, HITECH created four new tiers of civil monetary penalties, amended HIPAA to
make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in
federal courts to enforce HIPAA and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, U.S. state and foreign law equivalents may govern
the privacy and security of personal information (including key-coded data and health information_, many of which differ from each other in significant ways and may not have
the same effect, thus complicating compliance efforts. Efforts to ensure that our current and future business arrangements comply with applicable privacy and data security laws
and regulations will involve substantial costs. For example, the European General Data Protection Regulation, or GDPR, imposes several requirements relating to the consent of
the individuals to whom the personal data relates, the information provided to the individuals, the security and confidentiality of the personal data, data breach notification and
the use of third-party processors in connection with the processing of personal data. European data protection laws, such as the GDPR, also impose strict rules on the transfer of
personal  data  out  of  the  European  Economic  Area,  Switzerland  and  United  Kingdom.  Further,  the  GDPR  authorizes  the  imposition  of  penalties  (such  as  restrictions  or
prohibitions on personal data processing) and large fines for noncompliance, including the potential for fines of up to €20 million or 4% of the annual global revenues of the
noncompliant company, whichever is greater. The GDPR has increased our responsibility and potential liability in relation to personal data that we process or control compared
to prior EU law, including in clinical trials, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR and similar data protection
laws, which could divert management’s attention and increase our cost of doing business. Likewise, we expect that there will continue to be new proposed laws, regulations and
industry standards relating to privacy and data protection in the United States, the EU and other jurisdictions, such as the California Consumer Privacy Act of 2018, or CCPA,
which has been characterized as the first “GDPR-like” privacy statute to be enacted in the United States. Although the CCPA exempts certain data processed in the context of
clinical  trials,  the  CCPA,  to  the  extent  applicable  to  our  business  and  operations,  may  increase  our  compliance  costs  and  potential  liability  with  respect  to  the  personal
information  we  maintain  about  California  residents.  In  any  event,  it  is  possible  that  governmental  authorities  will  conclude  that  our  business  practices  do  not  comply  with
current or future statutes, regulations, agency guidance or case law involving applicable information security or privacy laws in light of the lack of applicable precedent and
regulations. Federal, state and foreign enforcement bodies have increased their scrutiny of biotechnology companies, which has led to a number of investigations, prosecutions,
convictions, fines, penalties and settlements in the industry.

Many states have also adopted laws similar to each of the above federal laws, which may be broader in scope and apply to items or services reimbursed by any third-party
payor, including commercial insurers. Several states and local jurisdictions have also enacted legislation requiring pharmaceutical companies to, among other things, establish
marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities, or register
their sales representatives, as well as prohibiting pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical companies for use
in sales and marketing, and prohibiting certain other sales and marketing practices.

Depending on the circumstances, failure to comply with these laws can result in significant penalties, including criminal, civil and/or administrative penalties, damages, fines,
disgorgement, debarment from government contracts, individual imprisonment, 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,  exclusion  from  government  programs,  refusal  to  allow  us  to  enter  into  supply
contracts, including government contracts, reputational harm, diminished profits and future earnings and the curtailment or restructuring of our operations, any of which could
adversely affect our business.

Healthcare Reform Measures

The United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals designed to change the healthcare system in
ways that could affect our ability to sell our products profitably. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting
changes in healthcare systems with the stated goals of containing healthcare 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.

For  example,  in  March  2010,  the  ACA  was  passed.  The  ACA  has  substantially  changed  health  care  financing  by  both  governmental  and  private  insurers,  and  significantly
affected  the  U.S.  pharmaceutical  industry.  The  ACA,  among  other  things,  subjected  manufacturers  to  new  annual  fees  and  taxes  for  specified  branded  prescription  drugs,
increased  the  minimum  Medicaid  rebates  owed  by  most  manufacturers  under  the  Medicaid  Drug  Rebate  Program,  expanded  health  care  fraud  and  abuse  laws,  revised  the
methodology  by  which  rebates  owed  by  manufacturers  to  the  state  and  federal  government  for  covered  outpatient  drugs  under  the  Medicaid  Drug  Rebate  Program  are
calculated, imposed an inflation penalty on new formulations of drugs, extended the Medicaid Drug Rebate program to utilization of prescriptions of individuals enrolled in
Medicaid  managed  care  organizations,  expanded  the  340B  program  which  caps  the  price  at  which  manufacturers  can  sell  covered  outpatient  pharmaceuticals  to  specified
hospitals, clinics and community health centers, and provided incentives to programs that increase the federal government’s comparative effectiveness research. There have
been executive, judicial and congressional challenges to certain aspects of the ACA. While Congress has not passed comprehensive repeal legislation, several bills affecting the
implementation of certain taxes under the ACA 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  ACA  on  certain  individuals  who  fail  to  maintain  qualifying  health  coverage  for  all  or  part  of  a  year  that  is  commonly
referred to as the “individual mandate”. Additionally, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the ACA-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. On December 14, 2018, a Texas
U.S. District Court Judge ruled that the ACA 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 5th 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 ACA 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 ACA, 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 ACA 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 ACA. It is unclear how the Supreme Court ruling, other such litigation, and the
healthcare reform measures of the Biden administration will impact the ACA.

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. In August 2011, the Budget Control Act of 2011, among other
things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least
$1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This
includes aggregate reductions of Medicare payments to providers up to 2% per fiscal year, which went into effect in April 2013 and, due to subsequent legislative amendments,
including the BBA, will remain 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.  In  addition,  in  January  2013,  President  Obama  signed  into  law  the  American  Taxpayer  Relief  Act  of  2012,  which,  among  other  things,  reduced  Medicare
payments to several categories of healthcare providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five
years.

Further, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several
recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the
relationship between pricing and manufacturer patient programs, reduce the cost of drugs under Medicare, 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, the Trump administration 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, HHS finalized a regulation removing safe harbor
protection for price reductions from pharmaceutical manufacturers to plan sponsors under Medicare 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  the  Trump  administration’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  are  increasingly  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. It is also
possible that additional governmental action is taken in response to the COVID-19 pandemic.

The Foreign Corrupt Practices Act

The Foreign Corrupt Practices Act, or FCPA, prohibits any U.S. individual or business from paying, offering or authorizing payment or offering of anything of value, directly or
indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business
in  obtaining  or  retaining  business.  The  FCPA  also  obligates  companies  whose  securities  are  listed  in  the  United  States  to  comply  with  accounting  provisions  requiring  the
companies to maintain books and records that accurately and fairly reflect all transactions of the companies, including international subsidiaries, and to devise and maintain an
adequate system of internal accounting controls for international operations.

Foreign Regulation

In  addition  to  regulations  in  the  United  States,  we  will  be  subject  to  a  variety  of  foreign  regulations  governing  clinical  trials  and  commercial  sales  and  distribution  of  our
products to the extent we choose to develop or sell any products outside of the United States. The approval process varies from country to country and the time may be longer
or shorter than that required to obtain FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from
country to country.

Employees and Human Capital Resources

As of December 31, 2020, we employed 22 full-time employees. We have never had a work stoppage, and none of our employees are represented by a labor organization or
under any collective bargaining arrangements. We consider our employee relations 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.

Segments and Geographic Information

We view our operations and manage our business as one operating segment. See our financial statements for a discussion of revenues, operating loss, net loss and total assets.
All of our assets were held in the United States for the years ended December 31, 2020 and 2019.

Corporate Information

We  were  incorporated  under  the  laws  of  the  State  of  Iowa  in  October  2006  and  were  reincorporated  under  the  laws  of  the  State  of  Delaware  in  May  2014.  Our  principal
executive offices are located at 1180 Celebration Boulevard, Suite 103, Celebration, FL 34747 and our telephone number is (321) 939-3416.

RISK FACTORS.

You should carefully consider all the risk factors and uncertainties described below, in addition to other information contained in this Annual Report on Form 10-K, including
the section of this report titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and related notes, before
investing in our common stock. If any of the following risks materialize, our business, financial condition and results of operations could be seriously harmed. This Annual
Report  on  Form  10-K  also  contains  forward-looking  statements  that  involve  risks  and  uncertainties.  Our  actual  results  could  differ  materially  from  those  anticipated  in  the
forward-looking statements because of factors that are described below and elsewhere in this Annual Report on Form 10-K.

Risks Related to the Development of Our Product Candidates

If  commercialization  of  AZSTARYS,  APADAZ  or  any  of  our  other  product  candidates,  if  approved,  are  not  successful,  or  we  experience  significant  delays  in
commercialization, our business will be harmed.

We  currently  generate  no  commercial  revenue  from  the  sale  of  any  prodrugs  and  we  may  never  be  able  to  successfully  commercialize  a  prodrug  product.  For  instance,  we
entered  into  the  KP415  License  Agreement  with  Commave  pursuant  to  which  we  granted  an  exclusive,  worldwide  license  to  Commave  to  develop,  manufacture
and commercialize AZSTARYS and KP484 worldwide. We cannot guarantee that Commave will be able to successfully develop, manufacture or commercialize AZSTARYS or
KP484 or that we will ever receive any future payments under the KP415 License Agreement. 
We have also entered into the APADAZ License Agreement with KVK pursuant to which we granted an exclusive license to KVK to commercialize APADAZ in the United
States,  but  we  cannot  guarantee  that  KVK  will  be  able  to  successfully  commercialize  APADAZ  or  that  we  will  ever  receive  any  payments  under  the  APADAZ  License
Agreement from commercial sales of APADAZ. 
We have invested substantially all our efforts and financial resources in the development of our proprietary LAT technology, the identification of potential product candidates
and the development of our product candidates. Our ability to generate revenue from APADAZ under the APADAZ License Agreement, AZSTARYS under the KP415 License
Agreement and generate revenue from any of our other product candidates will depend heavily on their successful development and eventual commercialization. The success of
AZSTARYS, APADAZ and any of our other product candidates will depend on several factors, including:

  ● successful completion of preclinical studies and requisite clinical trials;

  ● successful completion and achievement of endpoints in our clinical trials;

  ● demonstration that the risks involved with AZSTARYS, APADAZ and any of our other product candidates are outweighed by the benefits;

  ●

successful development of our manufacturing processes for AZSTARYS under the KP415 License Agreement, APADAZ under the APADAZ License Agreement and
for any of our other product candidates, including entering into and maintaining arrangements with third-party manufacturers;

  ●

successful completion of an FDA preapproval inspection of the facilities used to manufacture AZSTARYS, APADAZ and any of our other product candidates, as well as
select clinical trial sites;

  ●

receipt of timely marketing approvals from applicable regulatory authorities, including, if applicable, the determination by the DEA of the controlled substance schedule
for a product candidate, taking into account the recommendation of the FDA;

  ● obtaining differentiating claims in the labels for our product candidates;

  ●

obtaining and maintaining patent, trademark and trade secret protection and regulatory exclusivity for AZSTARYS, APADAZ and any of our other product candidates
and otherwise protecting our rights in our intellectual property portfolio;

  ● maintaining compliance with regulatory requirements, including cGMPs;

  ●

launching commercial sales of AZSTARYS under the KP415 License Agreement, APADAZ under the APADAZ License Agreement and launching commercial sales of
any of our other product candidates, if and when approved, whether alone or in collaboration with Commave or others;

  ● acceptance of AZSTARYS, APADAZ and any of our other product candidates, if approved, by patients, the medical community and third-party payors;

  ● competing effectively with other therapies;

  ● obtaining and maintaining healthcare coverage and adequate reimbursement; and

  ● maintaining a continued acceptable safety and efficacy profile of the prodrug products following approval.

Whether regulatory approval will be granted is unpredictable and depends upon numerous factors, including the substantial discretion of the regulatory authorities. If, following
submission, our NDA for a product candidate is not accepted for substantive review or approval, the FDA or other comparable foreign regulatory authorities may require that
we  conduct  additional  studies  or  clinical  trials,  provide  additional  data,  take  additional  manufacturing  steps  or  require  other  conditions  before  they  will  reconsider  our
application. If the FDA or other comparable foreign regulatory authorities require additional studies, clinical trials or data, we would incur increased costs and delays in the
marketing approval process, which may require us to expend more resources than we have available. 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  none  of  our  product  candidates  in  clinical  development  or  any  of  our  future  product  candidates  will  ever  obtain  regulatory  approval,  even  if  we  expend
substantial time and resources seeking such approval.

If  we  do  not  achieve  one  or  more  of  these  factors  in  a  timely  manner  or  at  all,  we  could  experience  significant  delays,  KVK  could  experience  an  inability  to  successfully
commercialize  APADAZ,  Corium  could  experience  an  inability  to  successfully  commercialize  AZSTARYS  or  any  of  our  other  product  candidates  covered  by  the  KP415
License Agreement, if approved, or we could experience an inability to successfully commercialize any of our other product candidates approved for marketing in the future, if
any, which would harm our business.

Our research and development activities are focused on discovering and developing proprietary prodrugs, and we are taking an innovative approach to discovering and
developing prodrugs, which may never lead to marketable prodrug products.

A key element of our strategy is to use our proprietary LAT technology to build a pipeline of prodrugs and progress product candidates based on these prodrugs through clinical
development  for  the  treatment  of  a  variety  of  diseases  and  conditions.  The  scientific  discoveries  that  form  the  basis  for  our  efforts  to  discover  and  develop  prodrugs  are
relatively new. As our scientific efforts are primarily focused on discovering novel prodrugs with new molecular structures, the evidence to support the feasibility of developing
product candidates based on these discoveries is both preliminary and limited. Although our research and development efforts to date have resulted in a pipeline of prodrug
product candidates, we may not be able to develop those product candidates into prodrugs that are bioequivalent, safe and effective and that have commercially significant
improvements over already approved drugs. Even if we are successful in continuing to build our pipeline, the potential product candidates that we identify may not be suitable
for clinical development, for reasons including being shown to have harmful side effects, a lack of efficacy, or other characteristics that indicate that they are unlikely to be
prodrugs that will receive marketing approval and achieve market acceptance. If APADAZ and AZSTARYS are not successfully commercialized under our APADAZ License
Agreement  or  KP415  License  Agreement  and  we  do  not  successfully  develop  and  commercialize  any  of  our  other  product  candidates  based  upon  our  proprietary  LAT
technology, we will not be able to obtain product revenue in future periods, which likely would result in significant harm to our financial position and adversely affect our stock
price.

28

 
 
 
 
 
 
 
If we are not able to obtain required regulatory approvals for any of our product candidates, or the approved labels are not sufficiently differentiated from other competing
products, we will not be able to commercialize them and our ability to generate revenue or profits or to raise future capital could be limited.

The  research,  testing,  manufacturing,  labeling,  packaging,  storage,  approval,  sale,  marketing,  advertising  and  promotion,  pricing,  export,  import  and  distribution  of  drug
products  are  subject  to  extensive  regulation  by  the  FDA  and  other  regulatory  authorities  in  the  United  States  and  other  countries,  which  regulations  differ  from  country  to
country and change over time. We are not permitted to market any of our product candidates in the United States until we receive approval of an NDA from the FDA, or in any
foreign countries until we receive the requisite approvals in such countries. In the United States, the FDA generally requires the completion of non-clinical testing and clinical
trials of each drug to establish its safety and efficacy and extensive pharmaceutical development to ensure its quality and other factors before an NDA is approved. Regulatory
authorities in other jurisdictions impose similar requirements. Of the large number of drugs in development, only a small percentage result in the submission of an NDA to the
FDA and even fewer are approved for commercialization.

Even if regulatory approval is obtained, subsequent safety, efficacy, quality or other issues can result in a product approval being suspended or withdrawn, or the approved label
for any approved product may not be sufficiently differentiated from other competing products to support market adoption thereof. On March 2, 2021, we announced that the
FDA approved the NDA for AZSTARYS, a once-daily product for the treatment of ADHD in patients ranging from six years and older. In February 2018, we announced that
the FDA approved the NDA for APADAZ for the short-term (no more than 14 days) management of acute pain severe enough to require an opioid analgesic and for which
alternative treatments are inadequate. Even with the regulatory approval of AZSTARYS and APADAZ by the FDA, we cannot guarantee that the FDA will approve any of our
other product candidates for commercial sale or approve any proposed label we may have for any such product candidate. If our development efforts for our product candidates,
including regulatory approval, are not successful for their planned indications or are delayed, or if adequate demand for our product candidates that are approved for marketing,
if any, is not generated, our business will be harmed.

The success of our product candidates will depend on the receipt and maintenance of regulatory approval and the issuance and maintenance of such approval is uncertain and
subject to a number of risks, including the following:

  ● the FDA or comparable foreign regulatory authorities, institutional review boards, or IRBs, or ethics committees may disagree with the design or conduct of our clinical

trials;

  ● the results of our clinical trials may not meet the level of statistical or clinical significance required by the FDA or other regulatory agencies for marketing approval or

for us to receive approval for claims that are necessary for commercialization;

  ● the dosing in a particular clinical trial may not be at an optimal level;

  ● patients in our clinical trials may suffer adverse effects for reasons that may or may not be related to our product candidates;

  ● the  data  collected  from  clinical  trials  may  not  be  sufficient  to  support  submissions  to  regulatory  authorities  or  to  obtain  regulatory  approval  in  the  United  States  or

elsewhere;

  ● the FDA or comparable foreign regulatory authorities may fail to approve the manufacturing processes or facilities of third-party manufacturers with which we contract

for clinical and commercial supplies or may later suspend or withdraw such approval;

  ● the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner rendering our clinical data insufficient

for approval; and 

  ● even if we obtain marketing approval in one or more countries, future safety or other issues could result in the suspension or withdrawal of regulatory approval in such

countries.

We have only limited experience in filing the applications necessary to gain regulatory approvals and have relied, and expect to continue to rely, on consultants and third-party
contract research organizations, or CROs, with expertise in this area to assist us in this process. Securing FDA approval requires the submission of extensive non-clinical and
clinical data, information about product manufacturing processes and inspection of facilities and supporting information to the FDA for each therapeutic indication to establish
a product candidate’s safety and efficacy for each indication and manufacturing quality. Additionally, we cannot guarantee that regulators will agree with our assessment of the
results of the clinical trials we have conducted or that any future trials will be successful.

Any  product  candidates  we  develop  may  prove  to  have  undesirable  or  unintended  side  effects,  toxicities  or  other  characteristics  that  may  preclude  our  obtaining  regulatory
approval or prevent or limit commercial use with respect to one or all intended indications.

The process of obtaining regulatory approvals is expensive, often takes many years, if approval is obtained at all, and can vary substantially based upon, among other things, the
type,  complexity  and  novelty  of  the  product  candidates  involved,  the  jurisdiction  in  which  regulatory  approval  is  sought  and  the  substantial  discretion  of  the  regulatory
authorities. Changes in the regulatory approval policy during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory
review for a submitted product application may cause delays in the approval or rejection of an application or may result in future withdrawal of approval. Regulatory approval
obtained in one jurisdiction does not necessarily mean that a product candidate will receive regulatory approval in all jurisdictions in which we may seek approval, but the
failure to obtain approval in one jurisdiction may negatively impact our ability to seek approval in a different jurisdiction. Failure to obtain regulatory marketing approval of our
product candidates in any indication will prevent us from commercializing those product candidates for that indication, and our ability to generate revenue will be impaired.

Disruptions  at  the  FDA  and  other  government  agencies  caused  by  funding  shortages  or  global  health  concerns  could  hinder  their  ability  to  hire,  retain  or  deploy  key
leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a timely manner or at all, which could
negatively impact our business.

The ability of the FDA to review and or approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory, and
policy changes, the FDA’s ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s ability to perform
routine  functions.  Average  review  times  at  the  agency  have  fluctuated  in  recent  years  as  a  result.  In  addition,  government  funding  of  other  government  agencies  that  fund
research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies may also slow the
time necessary for new drugs and biologics to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over
the last several years, including for 35 days beginning on December 22, 2018, the U.S. government has shut down several times and certain regulatory agencies, such as the
FDA, have had to furlough critical FDA employees and stop critical activities.

Separately,  in  response  to  the  COVID-19  pandemic,  in  March  2020  the  FDA  announced  its  intention  to  postpone  most  foreign  and  domestic  inspections  of  manufacturing
facilities  and  products,  and  subsequently,  in  July  2020,  restarted  routine  surveillance  inspections  of  domestic  manufacturing  facilities  on  a  risk-based  basis.  Regulatory
authorities outside the United States have adopted similar restrictions or other policy measures in response to the COVID-19 pandemic. If a prolonged government shutdown
occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities,
it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse
effect on our business.

30

 
 
 
 
 
If we, subject to the approval of Commave, or Commave themselves attempt to rely on Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act and the FDA does not
conclude that our product candidates are sufficiently bioequivalent, or have comparable bioavailability, to approved drugs, or if the FDA does not allow us or Commave to
pursue the 505(b)(2) NDA pathway as anticipated, the approval pathway for our product candidates will likely take significantly longer, cost significantly more and entail
significantly greater complications and risks than anticipated, and the FDA may not ultimately approve our product candidates.

A key element of our strategy is to seek FDA approval for most of our product candidates under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act, otherwise
known as the 505(b)(2) NDA pathway with any NDA submitted thereunder a 505(b)(2) NDA, where possible. The 505(b)(2) NDA pathway permits the filing of an NDA where
at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference.
Such reliance is typically predicated on a showing of bioequivalence or comparable bioavailability to an approved drug.

If the FDA does not allow us to pursue the 505(b)(2) NDA pathway as anticipated, or if we cannot demonstrate bioequivalence or comparable bioavailability of our product
candidates  to  approved  products,  we  may  need  to  conduct  additional  clinical  trials,  provide  additional  data  and  information,  and  meet  additional  standards  for  regulatory
approval. Moreover, even if the FDA does allow us to pursue the 505(b)(2) NDA pathway, depending on the product candidate, we may still need to conduct additional clinical
trials, including clinical trials to assess product safety or efficacy. For instance, subject to Commave approval, we currently plan on relying on the 505(b)(2) pathway for any
NDA submitted for KP484. However, we do not anticipate that the 505(b)(2) pathway will be available for every product candidate. For instance, it is possible we will only be
permitted to utilize the 505(b)(2) NDA pathway for either AZSTARYS or KP484, but not both. We utilized the 505(b)(2) NDA pathway for the AZSTARYS NDA which was
approved on March 2, 2021. If this were to occur, the time and financial resources required to obtain FDA approval for our product candidates, and complications and risks
associated with our product candidates, would likely substantially increase.

Moreover, our inability to pursue the 505(b)(2) NDA pathway could result in new competitive products reaching the market more quickly than our product candidates, which
could hurt our competitive position and our business prospects. Even if we are allowed to pursue the 505(b)(2) NDA pathway, we cannot assure you that our product candidates
will receive the requisite approvals for commercialization on a timely basis, if at all. Other companies may achieve product approval of similar products before we do, which
would delay our ability to obtain product approval, expose us to greater competition, and would require that we seek approval via alternative pathways, such as an abbreviated
new drug application, or ANDA, which is used for the development of generic drug products.

In addition, notwithstanding the approval of several products by the FDA under 505(b)(2) over the last few years, pharmaceutical companies and others have objected to the
FDA’s interpretation of 505(b)(2). If the FDA’s interpretation of 505(b)(2) is successfully challenged, the FDA may change its policies and practices with respect to 505(b)(2)
regulatory approvals, which could delay or even prevent the FDA from approving any NDA that we submit under 505(b)(2).

Even if  our  product  candidates  are  approved  under  505(b)(2),  the  approval  may  be  subject  to  limitations  on  the  indicated  uses  for  which  the  products  may  be  marketed,
including more limited subject populations than we request, may require that contraindications, warnings or precautions be included in the product labeling, including a boxed
warning, may be subject to other conditions of approval, or may contain requirements for costly post-marketing clinical trials, testing and surveillance to monitor the safety or
efficacy of the products, or other post-market requirements, such as a Risk Evaluation and Mitigation Strategy, or REMS. The FDA also may not approve a product candidate
with a label that includes the labeling claims necessary or desirable for the successful commercialization of that product candidate. Based upon currently approved products, we
anticipate that we will be required to conduct Phase 4 studies and to implement a REMS and will have a boxed warning for at least some of our product candidates, including
APADAZ.

31

 
 
 
 
 
 
 
 
The FDA may determine that any NDA we may submit under the 505(b)(2) regulatory pathway for any of our product candidates in the future is not sufficiently complete
to permit a substantive review.

If  we  were  to  submit  an  NDA  under  the  505(b)(2)  regulatory  for  any  of  our  product  candidates,  within  60  days  of  the  agency’s  receipt  of  our  NDA,  the  FDA  will  make  a
threshold determination of whether the NDA is sufficiently complete to permit a substantive review. This 60-day review period is referred to as the filing review. If the NDA is
sufficiently complete, the FDA will file the NDA. If the agency refuses to file the NDA, it will notify us and state the reason(s) for the refusal. The FDA may refuse to file our
NDA for various reasons, including but not limited to, if:

  ● the NDA is incomplete because it does not on its face contain the information required under the Federal Food, Drug and Cosmetic Act or the FDA’s regulations;

  ● the NDA does not contain a statement that each non-clinical laboratory study was conducted in compliance with good laboratory practices requirements, or for each

study not so conducted, a brief statement of the reason for the noncompliance;

  ● the NDA does not contain a statement that each clinical trial was conducted in compliance with the IRB regulations or was not subject to those regulations, and the

agency’s informed consent regulations or a brief statement of the reason for noncompliance; or

  ● the drug is a duplicate of a listed drug approved before receipt of the NDA and is eligible for approval under an ANDA for generic drugs. 

In its procedures, the FDA has stated that it could find an NDA submitted under the Section 505(b)(2) regulatory pathway incomplete and refuse to file it if the NDA, among
other reasons:

  ● fails to include appropriate literature or a listed drug citation to support the safety or efficacy of the drug product;

  ● fails to include data necessary to support any aspects of the proposed drug that represent modifications to the listed drug(s) relied upon;

  ● fails to provide a bridge, for example by providing comparative bioavailability data, between the proposed drug product and the listed drug product to demonstrate that

such reliance is scientifically justified;

  ● uses an unapproved drug as a reference product for the bioequivalence study; or

  ● fails to provide a patent certification or statement as required by the FDA’s regulations where the 505(b)(2) NDA relies on one or more listed drugs.

Additionally, the FDA will refuse to file an NDA if an approved drug with the same active moiety is entitled to five years of exclusivity, unless the exclusivity period has
elapsed,  or  unless  four  years  of  the  five-year  period  have  elapsed,  and  the  NDA  contains  a  certification  of  patent  invalidity  or  non-infringement.  An  active  moiety  is  the
molecule  or  ion,  excluding  those  appended  portions  of  the  molecule  that  cause  the  drug  to  be  an  ester,  salt  (including  a  salt  with  hydrogen  or  coordination  bond)  or  other
noncovalent derivative (such as a complex, chelate, or clathrate) of the molecule, responsible for the therapeutic activity of the drug substance.

If the FDA refuses to file an NDA submitted by us, we may amend the NDA and resubmit it. In such a case, the FDA will again review the NDA and determine whether it may
be filed. There can be no assurance that the FDA will file any NDA submitted by us in the future. If the agency refuses to file an NDA, we will need to address the deficiencies
cited by the FDA, which could substantially delay the review process.

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 and commercialization of our product candidates.

The risk of failure for our product candidates is high. It is impossible to predict when or if any of our current product candidates will prove effective or safe in humans and will
receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical development
and then conduct clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical testing is expensive, difficult to design and implement, can
take many years to complete and is uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical studies and
early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Interpretation of
results from early, usually smaller, studies that suggest positive trends in some subjects, requires caution. Results from later stages of clinical trials enrolling more subjects may
fail to show the desired safety and efficacy results or otherwise fail to be consistent with the results of earlier trials of the same product candidates. Later clinical trial results
may not replicate earlier clinical trials for a variety of reasons, including differences in trial design, different trial endpoints, or lack of trial endpoints in exploratory studies,
subject  population,  number  of  subjects,  subject  selection  criteria,  trial  duration,  drug  dosage  and  formulation  and  lack  of  statistical  power  in  the  earlier  studies.  Moreover,
preclinical  and  clinical  data  are  often  susceptible  to  varying  interpretations  and  analyses,  and  many  companies  that  have  believed  their  product  candidates  performed
satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products.

We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval or commercialize
our product candidates, including:

  ● regulators  or  IRBs  may  not  authorize  us  or  our  investigators  to  commence  a  clinical  trial,  conduct  a  clinical  trial  at  a  prospective  trial  site  or  amend  clinical  trial

protocols as needed;

  ● we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical trial protocols with prospective trial sites and CROs;

  ● clinical  trials  of  our  product  candidates  may  produce  negative  or  inconclusive  results,  including  failure  to  demonstrate  statistical  significance  in  cases  where  that  is

required, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon prodrug development programs; 

  ● the number of subjects required for clinical trials of our product 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 at a higher rate than we anticipate;

  ● our third-party contractors may fail to comply with regulatory requirements or trial protocols, 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  research  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 product candidates may be greater than we anticipate, including if we are not able to pursue the 505(b)(2) NDA pathway for approval of

our product candidates;

  ● we will need to pay substantial application user fees, which we may not be able to afford;

  ● the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates may be insufficient or inadequate;

  ● we may abandon our development program or programs based on the changing regulatory or commercial environment;

  ● regulatory authorities may not agree with our trial design or implementation; and

  ● our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, regulators or IRBs to suspend or terminate

the trials.

33

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, if we are unable to successfully
complete  clinical  trials  of  our  product  candidates  or  other  testing,  if  the  results  of  these  trials  or  tests  are  not  positive  or  are  only  modestly  positive  or  if  there  are  safety
concerns, we may:

  ● be delayed in obtaining marketing approval for our product candidates;

  ● not obtain marketing approval at all;

  ● obtain approval for indications or patient populations that are not as broad as intended or desired;

  ● obtain approval but without the claims necessary for us to successfully commercialize our product candidates;

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

  ● be subject to additional post-marketing testing, surveillance, or other requirements, such as REMS; or

  ● have the product removed from the market after obtaining marketing approval.

Our  prodrug  development  costs  may  also  increase  if  we  experience  delays  in  testing  or  obtaining  marketing  approvals. Additionally,  if  we  do  not  successfully  develop  any
product candidates subject to the KP415 License Agreement, we may not be eligible to receive any future payments under the KP415 License Agreement. 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 we may have the exclusive right to commercialize our product candidates or allow our competitors to bring
products to market before we do and impair our ability to successfully commercialize our product candidates.

34

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

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

Our  decision  to  seek  approval  of  our  product  candidates  under  the  505(b)(2)  NDA  pathway,  if  available,  may  increase  the  risk  that  patent  infringement  suits  are  filed
against us, which would delay the FDA’s approval of such product candidates.

Regarding  any  NDA  that  we  may  submit  under  the  505(b)(2)  NDA  pathway,  if  there  are  patents  that  claim  the  approved  drug  contained  in  our  product  candidates  and
referenced in our 505(b)(2) NDA, we must certify to the FDA and notify the patent holder that any patents listed for the approved drug in the FDA’s Orange Book publication
are invalid, unenforceable or will not be infringed by the manufacture, use or sale of our prodrug. If a patent infringement lawsuit is filed against us within 45 days of its receipt
of notice of our certification, the FDA is automatically prevented from approving our 505(b)(2) NDA until the earliest of 30 months, expiration of the patent, settlement of the
lawsuit or a court decision in the infringement case that is favorable to us, or such shorter or longer period as may be ordered by a court. Such actions are routinely filed by
patent  owners.  Accordingly,  we  may  invest  considerable  time  and  expense  in  the  development  of  our  product  candidates  only  to  be  subject  to  significant  delay  and  patent
litigation before our product candidates may be commercialized. We may not be successful in defending any patent infringement claim. Even if we are found not to infringe, or
a plaintiff’s patent claims are found invalid or unenforceable, defending any such infringement claim would be expensive and time-consuming, and would delay launch of our
product candidates and distract management from their normal responsibilities.

We may not be successful in our efforts to develop a prodrug-based product that might allow us to seek a rare pediatric disease priority review voucher.

The  FDA  has  awarded  rare  pediatric  disease  priority  review  vouchers  to  sponsors  of  drug  candidates  to  treat  rare  pediatric  disease,  if  the  treatment  sponsors  apply  for  this
designation  and  meet  certain  criteria.  Under  this  program,  upon  the  approval  of  a  qualifying  NDA,  for  the  treatment  of  a  rare  pediatric  disease,  the  sponsor  of  such  an
application would be eligible for a rare pediatric disease priority review voucher that can be used to obtain priority review for a subsequent NDA. The priority review voucher
may be sold or transferred an unlimited number of times.

We previously announced a technology licensing agreement with Genco Sciences, LLC to develop prodrug-based therapy for potential rare pediatric indications of Tourette’s
Syndrome with ADHD. We cannot guarantee that we will be successful in this effort to develop such a prodrug-based therapy. Additionally, we cannot guarantee that the FDA
would grant us a rare pediatric disease designation for such a prodrug-based product candidate. Even if the FDA grants us a rare pediatric disease designation for one of our
prodrug-based product candidates, designation of a drug as a drug for a rare pediatric disease does not guarantee that an NDA for such drug will meet the eligibility criteria for a
rare pediatric disease priority review voucher at the time the application is approved.

AZSTARYS, APADAZ and certain of our other product candidates contain controlled substances, the manufacture, use, sale, importation, exportation, prescribing and
distribution of which are subject to regulation by the DEA.

Before we can commercialize any of our products or product candidates, if approved, the DEA will need to determine the controlled substance schedule, taking into account the
recommendation of the FDA. This may be a lengthy process that could delay our marketing of a product candidate and could potentially diminish any regulatory exclusivity
periods for which we may be eligible. The FDA has recommended that AZSTARYS be regulated as a "controlled substance" as defined in the CSA. For APADAZ, the DEA has
determined  it  to  be  a  Schedule  II  drug.  We  expect  that  most  of  our  other  product  candidates,  including  KP484  and  KP879,  if  approved,  will  be  regulated  as  “controlled
substances”  as  defined  in  the  CSA  and  the  implementing  regulations  of  the  DEA,  which  establish  registration,  security,  recordkeeping,  reporting,  storage,  distribution,
importation,  exportation,  inventory,  quota  and  other  requirements  administered  by  the  DEA.  These  requirements  are  applicable  to  us,  to  our  contract  manufacturers  and  to
distributors, prescribers and dispensers of our product candidates. The DEA regulates the handling of controlled substances through a closed chain of distribution. This control
extends to the equipment and raw materials used in their manufacture and packaging, in order to prevent loss and diversion into illicit channels of commerce. A number of
states and foreign countries also independently regulate these drugs as controlled substances.

The  DEA  regulates  controlled  substances  as  Schedule  I,  II,  III,  IV  or  V  substances.  Schedule  I  substances  by  definition  have  no  established  medicinal  use  and  may  not  be
marketed or sold in the United States. A pharmaceutical product may be listed as Schedule II, III, IV or V, with Schedule II substances considered to present the highest risk of
abuse and Schedule V substances the lowest relative risk of abuse among such substances. Schedule II drugs are those that meet the following characteristics:

  ● the drug has a high potential for abuse;

  ● the drug has a currently accepted medical use in treatment in the United States or a currently accepted medical use with severe restrictions; and

  ● abuse of the drug may lead to severe psychological or physical dependence.

We expect that most of our current product candidates may be listed by the DEA as Schedule II controlled substances under the CSA. If our product candidates are listed as
Schedule II controlled substances, then the importation of the APIs for our product candidates, as well as the manufacture, shipping, storage, sales and use of the products, will
be subject to a high degree of regulation. In addition to maintaining an importer and/or exporter registration, importers and exporters of controlled substances must obtain a
permit for every import of a Schedule I or II substance and a narcotic substance in Schedule III, IV and V, as well as every export of a Schedule I or II substance and a narcotic
substance in Schedule III and IV. For all other drugs in Schedule III, IV and V, importers and exporters must submit an import or export declaration. Schedule II drugs are
subject to the strictest requirements for registration, security, recordkeeping and reporting. Also, distribution and dispensing of these drugs are highly regulated. For example, all
Schedule II drug prescriptions must be signed by a physician, physically presented to a pharmacist and may not be refilled without a new prescription. Electronic prescriptions
may also be permissible depending on the state, so long as the prescription complies with the DEA’s requirements for electronic prescriptions.

Controlled substances classified in Schedule III, IV, and V are also subject to registration, recordkeeping, reporting and security requirements. For example, Schedule III drug
prescriptions must be authorized by a physician and may not be refilled more than six months after the date of the original prescription or more than five times. A prescription
for  controlled  substances  classified  in  Schedules  III,  IV  and  V  issued  by  a  physician,  may  be  communicated  either  orally,  in  writing  or  by  facsimile  to  the  pharmacies.
Controlled  substances  that  are  also  classified  as  narcotics,  such  as  hydrocodone,  oxycodone  and  hydromorphone,  are  also  subject  to  additional  DEA  requirements,  such  as
manufacturer reporting of the import of narcotic raw material.

Annual registration is required for any facility that manufactures, distributes, dispenses, imports or exports any controlled substance. The registration is specific to the particular
location,  activity  and  controlled  substance  schedule.  For  example,  separate  registrations  are  needed  for  import  and  manufacturing,  and  each  registration  will  specify  which
schedules of controlled substances are authorized. Similarly, separate registrations are also required for separate facilities. Acquisition and distribution transactions must also be
reported for Schedule I and II controlled substances, as well as Schedule III narcotic substances.

In addition, a DEA quota system controls and limits the availability and production of controlled substances in Schedule I or II. Because most of our product candidates may be
regulated as Schedule II controlled substances, they may be subject to the DEA’s production and procurement quota scheme. The DEA establishes annually an aggregate quota
for how much of a controlled substance may be produced in total in the United States based on the DEA’s estimate of the quantity needed to meet legitimate scientific and
medicinal needs. Manufacturers of Schedule I and II controlled substances are required to apply for quotas on an annual basis. If we or our contract manufacturers or suppliers
do not obtain a sufficient quota from the DEA, we may not be able to obtain sufficient quantities of these controlled substances in order to complete our clinical trials or meet
commercial demand, if our product candidates are approved for marketing.

Because of their restrictive nature, these laws and regulations could limit commercialization of our product candidates containing controlled substances. States may also have
their  own  controlled  substance  laws  that  may  further  restrict  and  regulate  controlled  substances.  Failure  to  comply  with  these  laws  and  regulations  could  also  result  in
withdrawal  of  our  DEA  registrations,  disruption  in  manufacturing  and  distribution  activities,  consent  decrees,  criminal  and  civil  penalties  and  state  actions,  among  other
consequences.

If we experience delays or difficulties in the enrollment of subjects in clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented.

We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible subjects 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. If we are not successful at enrolling subjects in one clinical trial, it may affect when we are able to initiate our next clinical trial, which could result in significant
delays in our efforts to pursue regulatory approval of and commercialize our product candidates. In addition, some of our competitors have ongoing clinical trials to treat the
same indications as our product candidates, and subjects who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors. Subject
enrollment is affected by other factors including:

  ● the size and nature of the subject population specified in the trial protocol;

  ● the eligibility criteria for the study in question;

  ● the perceived risks and benefits of the product candidate under study;

  ● the fact that the product candidate is a controlled substance;

  ● severe or unexpected drug-related adverse events experienced by subjects in a clinical trial;

  ● the availability of drugs approved to treat the diseases or conditions under study;

  ● the efforts to facilitate timely enrollment in clinical trials;

  ● the patient referral practices of physicians;

  ● the severity of the disease or condition under investigation;

  ● the ability to obtain and maintain subject informed consent;

  ● the ability to retain subjects in the clinical trial and their return for follow-up;

  ● the clinical trial design, including required tests, procedures and follow-up;

  ● the ability to monitor subjects adequately during and after treatment;

  ● delays in adding new investigators and clinical sites;

  ● withdrawal of clinical trial sites from clinical trials; and

  ● the proximity and availability of clinical trial sites for prospective subjects.

Our inability to enroll a sufficient number of subjects for clinical trials would result in significant delays and could require us to abandon one or more clinical trials altogether.
Enrollment delays in these clinical trials may result in increased development costs for our product candidates, which could cause our value to decline and limit our ability to
obtain additional financing.

Our clinical trials may fail to demonstrate the safety and efficacy of our product candidates, or serious adverse or unacceptable side effects may be identified during the
development of our product candidates, which could prevent or delay regulatory approval and commercialization, increase our costs or necessitate the abandonment or
limitation of the development of some of our product candidates.

Before obtaining regulatory approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical studies and
clinical trials that our product 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 product candidate studied for the target indication.

If  our  product  candidates  are  associated  with  side  effects  in  clinical  trials  or  have  characteristics  that  are  unexpected,  we  may  need  to  abandon  their  development  or  limit
development  to  more  narrow  uses  or  subpopulations  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 product candidates. Many product candidates that initially showed promise in early stage testing have
later been found to cause side effects that prevented further development of the product candidate.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product 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 research programs and product candidates that we identify for specific indications. As a result, we
may forego or delay pursuit of opportunities with other product 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  research  and  development
programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target
market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in
which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

Social issues around the abuse of opioids and stimulants, including law enforcement concerns over diversion and regulatory efforts to combat abuse, could decrease the
potential market for AZSTARYS, APADAZ or any of our other applicable product candidates.

Media stories regarding prescription drug abuse and the diversion of opioids, stimulants and other controlled substances are commonplace. Law enforcement and regulatory
agencies may apply policies that seek to limit the availability of opioids and stimulants. Such efforts may inhibit the ability to commercialize AZSTARYS under the KP415
License  Agreement,  APADAZ  under  the  APADAZ  License  Agreement  or  to  commercialize  any  of  our  other  applicable  product  candidates.  Aggressive  enforcement  and
unfavorable publicity regarding, for example, the use or misuse of hydrocodone or other opioid drugs and stimulants, the limitations of abuse-deterrent formulations, public
inquiries and investigations into prescription drug abuse, litigation or regulatory activity, sales, marketing, distribution or storage of our products could harm our reputation.
Such negative publicity could reduce the potential size of the market for AZSTARYS, APADAZ or any of our other applicable product candidates and decrease the revenue we
are able to generate from their sale, if approved. Similarly, to the extent prescription drug abuse becomes a less prevalent or less urgent public health issue, regulators and third-
party payors may not be willing to pay a premium for formulations with improved attributes of opioids or stimulants.

Additionally, efforts by the FDA and other regulatory bodies to combat abuse of opioids and stimulants may negatively impact the market for AZSTARYS, APADAZ and any
of our other applicable product candidates. For example, in April 2014, the FDA approved class-wide labeling changes to the indications for use of all approved ER/LA opioids,
so that ER/LA opioids will be indicated only for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative
treatment  options  are  inadequate. These  changes  have  reduced  the  number  of  prescriptions  for  opioids  written  by  physicians  and  negatively  impact  the  potential  market  for
APADAZ or our other applicable product candidates. The FDA also held a public meeting in October 2014, on the development and regulation of abuse-deterrent formulations
of  opioid  medications.  Further,  the  Centers  for  Disease  Control  and  Prevention  previously  issued  draft  guidelines  for  the  prescribing  of  opioids  for  chronic  pain,  providing
recommendations  for  primary  care  providers  prescribing  opioids  for  chronic  pain  on  when  to  initiate  or  continue  opioids,  opioid  selection  and  discontinuation,  and  the
assessment of the risk and addressing harms of opioid use, among other areas. It is possible that FDA, or other regulatory bodies, will announce new regulatory initiatives at any
time that may increase the regulatory burden or decrease the commercial opportunity for AZSTARYS, APADAZ or any of our other applicable product candidates.

Risks Related to Our Financial Position and Capital Needs

Any failure to maintain effective internal control over financial reporting could harm us.

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Internal  control  over  financial  reporting  is  a  process
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. generally accepted
accounting principles. If our management is unable to conclude that we have effective internal control over financial reporting, or to certify the effectiveness of such controls, or
if  material  weaknesses  in  our  internal  controls  are  identified  in  the  future,  we  could  be  subject  to  regulatory  scrutiny  and  a  loss  of  public  confidence,  which  could  have  a
material adverse effect on our business and our stock price. In addition, if we do not maintain adequate financial and management personnel, processes and controls, we may
not be able to manage our business effectively or accurately report our financial performance on a timely basis, which could cause a decline in our common stock price and
adversely affect our results of operations and financial condition.

We have incurred significant recurring negative net operating cash flows. We expect to incur minimal positive net operating cash flows or negative net operating cash
flows over the next several years and may never achieve or maintain profitability.

We have had recurring negative net operating cash flows and, as of December 31, 2020, had an accumulated deficit of $258.5 million. For the years ended December 31, 2020
and 2019 net cash used in operations was $1.9 million and of $23.7 million, respectively. We have financed our operations through December 31, 2020 with funds raised in
private placements of redeemable convertible preferred stock, in the issuance of convertible promissory notes and term debt, our initial public offering and other public and
private  offerings  of  our  common  stock,  as  well  as  through  revenue  received  under  the  KP415  License  Agreement,  the  Corium  Consulting  Agreement  and  other  consulting
arrangements.

We have devoted substantially all of our financial resources and efforts to research and development, including preclinical studies and clinical trials. We are in various stages of
development  of  our  product  candidates,  and  we  have  only  completed  development  of,  and  received  regulatory  approval  for,  two  products,  AZSTARYS  and  APADAZ.  We
expect to continue to incur significant expenses and operating losses over the next several years and our net losses may fluctuate significantly from quarter to quarter and year
to year as we:

  ● continue our ongoing preclinical studies, clinical trials and our product development activities for our pipeline of product candidates;

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

  ● continue research and preclinical development and initiate clinical trials of our product candidates;

  ● seek to discover and develop additional product candidates either internally or in partnership with other pharmaceutical companies;

  ● adapt our regulatory compliance efforts to incorporate requirements applicable to marketed products;

  ● maintain, expand and protect our intellectual property portfolio;

  ● incur additional legal, accounting and other expenses in operating as a public company; and

  ● add operational systems and personnel, if needed, to support any future commercialization efforts.

To  become  and  remain  profitable,  we  must  succeed  in  developing  and  eventually  commercializing  prodrugs  that  generate  significant  revenue.  This  will  require  us  to  be
successful  in  a  range  of  challenging  activities,  including  completing  preclinical  studies  and  clinical  trials  and  obtaining  regulatory  approval  of  our  product  candidates,  and
manufacturing, marketing and selling, whether ourselves or through a license with a third party, any of our product candidates for which we may obtain regulatory approval, as
well  as  discovering  and  developing  additional  product  candidates.  We  are  in  various  stages  of  these  activities  for  our  product  candidates  and  we  cannot  guarantee  that  any
strategy we adopt will be successful. For instance, 
in September 2019, we entered into the KP415 License Agreement with Commave pursuant to which we granted an exclusive, worldwide license to Commave to develop,
manufacture and commercialize AZSTARYS and KP484 worldwide. We cannot guarantee that Commave will be able to successfully develop, manufacture or commercialize
AZSTARYS, or KP484, if approved, or that we will ever receive any future payments under the KP415 License Agreement. In addition, 
in October 2018, we entered into the APADAZ License Agreement with KVK pursuant to which we granted an exclusive license to KVK to commercialize APADAZ in the
United States. We cannot guarantee that KVK will be able to successfully commercialize APADAZ or that we will ever receive any payments under the APADAZ License
Agreement  from  commercial  sales  of  APADAZ.  We  may  never  succeed  in  commercialization  activities  and,  even  if  we  do,  may  never  generate  revenue  that  is  significant
enough to achieve profitability.

In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. This outbreak is causing major disruptions to businesses and markets
worldwide as the virus spreads. We cannot predict what the long-term effects of this pandemic and the resulting economic disruptions may have on our liquidity and results of
operations. The extent of the effect of the COVID-19 pandemic on our liquidity and results of operations will depend on a number future developments, including the duration,
spread and intensity of the pandemic, and governmental, regulatory and private sector responses, all of which are uncertain and difficult to predict. The COVID-19 pandemic
may make it more difficult for us to enroll patients in any future clinical trials or cause delays in the regulatory approval of our product candidates. A portion of our projected
revenue is based upon the achievement of milestones in the KP415 License Agreement associated with regulatory matters that may be impacted by the COVID-19 pandemic.
As a result, we cannot predict what, if any, impact that the COVID-19 pandemic may have on our ability to achieve these milestones. If the pandemic continues to be a severe
worldwide crisis, it could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

Because of the numerous risks and uncertainties associated with prodrug 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  currently  expected,  or  if  there  are  any  delays  in  the
initiation and completion of our clinical trials or the development of any of our product 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 our value and could impair our ability to raise capital, expand our business, maintain our research and development efforts, obtain product approvals, diversify our
product offerings or continue our operations. A decline in our value could also cause you to lose all or part of your investment.

Identifying potential product candidates and conducting preclinical studies and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete,
and we may not generate the necessary data or results required to obtain regulatory approval for our product candidates or claims necessary to make such candidates profitable
and  achieve  product  sales.  In  addition,  AZSTARYS, APADAZ  or  any  of  our  other  product  candidates,  if  approved,  may  not  achieve  commercial  success.  Our  commercial
revenue, if any, will be derived from sales of prodrug products. We cannot guarantee that Commave will be able to successfully commercialize AZSTARYS or any of the other
product candidates subject to the KP415 License Agreement, even if approved, that KVK will be able to successfully commercialize APADAZ or that we will ever receive any
payments under the KP415 License Agreement from the commercial sales of AZSTARYS or any future payments under the KP415 License Agreement or payment under the
APADAZ License Agreement from commercial sales of APADAZ. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives.
Adequate additional financing may not be available to us on acceptable terms, or at all. To the extent that we raise additional capital through the sale of equity or debt securities,
the  terms  of  those  securities  or  debt  may  restrict  our  ability  to  operate.  Any  future  debt  financing  and  equity  financing,  if  available,  may  involve  agreements  that  include,
covenants  limiting  and  restricting  our  ability  to  take  specific  actions,  such  as  incurring  additional  debt,  making  capital  expenditures,  entering  into  profit-sharing  or  other
arrangements  or  declaring  dividends.  If  we  raise  additional  funds  through  collaborations,  strategic  alliances  or  marketing,  distribution  or  licensing  arrangements  with  third
parties, we may be required to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that
may not be favorable to us. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient
funds for our current or future operating plans. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or altogether cease our
research and development programs or future commercialization efforts.

40

 
 
 
 
 
 
 
We may need additional funding to pursue our business objectives. If we are unable to raise capital when needed, we could be forced to delay, reduce or altogether cease
our prodrug development programs or commercialization efforts or cease operations altogether.

We  expect  that  our  only  sources  of  revenues  will  be  through  payments  arising  from  our  license  agreements  with  Commave  and  KVK,  or  through  the  Corium  Consulting
Agreement or other potential consulting arrangements and any other future arrangements related to one of our other product candidates. We cannot guarantee that we will be
able  to  generate  sufficient  proceeds  from  the  KP415  License  Agreement,  the  APADAZ  License  Agreement,  the  Corium  Consulting  Agreement  or  other  consulting
arrangements,  or  be  successful  in  completing  other  transactions,  that  will  fully  fund  our  operating  expenses.  Further,  the  economic  uncertainty  surrounding  the  COVID-
19 pandemic may dramatically reduce our ability to secure debt or equity financing necessary to support our operations. If we are delayed in obtaining additional funding or are
unable  to  complete  a  strategic  transaction,  we  may  discontinue  our  development  activities  on  our  product  candidates  or  discontinue  our  operations.  Our  future  capital
requirements will depend on many factors, including:

  ●

the progress and results of our preclinical studies, clinical trials, chemistry, manufacturing and controls, or CMC, and other product development and commercialization
activities;

  ● the scope, progress, results and costs of preclinical development, laboratory testing and clinical trials for our product candidates;

  ● the ability to obtain differentiating claims in the labels for our product candidates;

  ● the number and development requirements of other product candidates that we may pursue;

  ● the costs, timing and outcome of regulatory review of our product candidates;

  ● the efforts necessary to institute post-approval regulatory compliance requirements;

  ●

the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for
which we receive marketing approval;

● the  commercial  revenue,  if  any,  received  from  commercial  sales  of  AZSTARYS  under  our  KP415  License  Agreement,  APADAZ  under  our  APADAZ  License
Agreement, or any of our other product candidates subject to the terms of the KP415 License agreement, or sales of our other product candidates for which we receive
marketing approval in the future, which may be affected by market conditions, including obtaining coverage and adequate reimbursement of AZSTARYS, APADAZ, or
any of our other product candidates, from third-party payors, including government programs and managed care organizations, and competition within the therapeutic
class to which AZSTARYS, APADAZ, or any our other product candidates are assigned;

  ●

the  success  of  our  partner,  Commave,  in  commercializing  AZSTARYS,  or  the  successful  development  of  other  Additional  Products  or  other  Licensed  Products  in
accordance with the terms of the KP415 License Agreement;

  ●

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; and

  ● the extent to which we acquire or in-license other product candidates and technologies.

We may not be entitled to forgiveness of our recently received Paycheck Protection Program loan, and our application for the Paycheck Protection Program loan could in
the future be determined to have been impermissible or could result in damage to our reputation.

On April 23, 2020 we received proceeds of $0.8 million from a loan, or the PPP Loan, under the Paycheck Protection Program, or the PPP, of the recently enacted Coronavirus
Aid, Relief, and Economic Security Act, or the CARES Act, a portion of which may be forgiven, which we used to retain current employees, maintain payroll and make lease
and  utility  payments.  The  PPP  Loan  matures  on  April  23,  2022  and  bears  annual  interest  at  a  rate  of  1.0%.  Payments  of  principal  and  interest  on  the  PPP  Loan
were originally deferred for the first six months of the PPP Loan term. Thereafter, we would have been required to pay the lender equal monthly payments of principal and
interest.

The CARES Act and the PPP provide a mechanism for forgiveness of up to the full amount borrowed. Under the PPP, we may apply for and be granted forgiveness for all or
part of the PPP Loan. The amount of loan proceeds eligible for forgiveness was originally based on a formula that takes into account a number of factors, including the amount
of loan proceeds used by us during the eight-week period after the loan origination for certain purposes, including payroll costs, interest on certain mortgage obligations, rent
payments  on  certain  leases,  and  certain  qualified  utility  payments,  provided  that  at  least  75%  of  the  loan  amount  was  used  for  eligible  payroll  costs.  Subject  to  the  other
requirements and limitations on loan forgiveness, only loan proceeds spent on payroll and other eligible costs during the covered eight-week period would have qualified for
forgiveness.

On June 5, 2020, President Trump signed into law the PPP Flexibility Act of 2020, or the Flexibility Act, which among other things provided the following important changes
to the PPP:

● Extended  the  covered  period  for  loan  forgiveness  from  eight  weeks  after  the  date  of  loan  disbursement  to  24  weeks  after  the  date  of  loan  disbursement,  providing
substantially greater flexibility for borrowers to qualify for loan forgiveness. Borrowers who had already received PPP loans retained the option to use an eight-week
covered period.

● Lowered the requirements that 75 percent of a borrower’s loan proceeds must be used for payroll costs and that 75 percent of the loan forgiveness amount must have
been spent on payroll costs during the 24-week loan forgiveness covered period to 60 percent for each of these requirements. If a borrower uses less than 60 percent of
the  loan  amount  for  payroll  costs  during  the  forgiveness  covered  period,  the  borrower  will  continue  to  be  eligible  for  partial  loan  forgiveness,  subject  to  at  least
60 percent of the loan forgiveness amount having been used for payroll costs.

● Provided a safe harbor from reductions in loan forgiveness based on reductions in full-time equivalent employees for borrowers that are unable to return to the same
level of business activity the business was operating at before February 15, 2020, due to compliance with requirements or guidance issued between March 1, 2020 and
December 31, 2020 by the Secretary of Health and Human Services, the Director of the Centers for Disease Control and Prevention, or the Occupational Safety and
Health Administration, related to worker or customer safety requirements related to COVID–19.

● Provided a safe harbor from reductions in loan forgiveness based on reductions in full-time equivalent employees, to provide protections for borrowers that are both
unable  to  rehire  individuals  who  were  employees  of  the  borrower  on  February  15,  2020,  and  unable  to  hire  similarly  qualified  employees  for  unfilled  positions  by
December 31, 2020.

● Increased  to  five  years  the  maturity  of  PPP  loans  that  are  approved  by  the  U.S.  Small  Business  Administration,  or  the  SBA,  (based  on  the  date  SBA  assigns  a  loan

number) on or after June 5, 2020.

● Extended the deferral period for borrower payments of principal, interest, and fees on PPP loans to the date that SBA remits the borrower’s loan forgiveness amount to

the lender (or, if the borrower does not apply for loan forgiveness, 10 months after the end of the borrower’s loan forgiveness covered period).

Based on the changes provided by the Flexibility Act we plan to take advantage of (i) the extended covered period for loan forgiveness from eight weeks to 24 weeks, (ii) the
lowered requirement that a certain percentage of loan proceeds must be used for payroll costs from 75 percent to 60 percent, (iii) the extended deferral period for payments of
principal,  interest  and  fees  from  six  months  after  loan  disbursement  to  10  months  after  the  SBA  remits  the  borrower’s  loan  forgiveness  amount  to  the  lender  and  (iv)  take
advantage of an safe harbor provisions as applicable. We will be required to repay any portion of the outstanding principal that is not forgiven, along with accrued interest, in
accordance  with  the  amortization  schedule  described  above.  Based  on  the  changes  provided  by  the  Flexibility  Act  we  expect  that  substantially  all  of  the  PPP  loan  will  be
forgiven, however, we cannot provide any assurance that we will be eligible for loan forgiveness, or that any amount of the PPP Loan will ultimately be forgiven by the SBA.
We submitted our application for loan forgiveness of the full amount of the PPP Loan under the applicable SBA guidance and are waiting for a decision on that application.

In order to apply for the PPP Loan, we were required to certify, among other things, that the current economic uncertainty made the PPP Loan request necessary to support our
ongoing operations. We made this certification in good faith after analyzing, among other things, our financial situation and access to alternative forms of capital, and believe
that  we  satisfied  all  eligibility  criteria  for  the  PPP  Loan,  and  that  our  receipt  of  the  PPP  Loan  is  consistent  with  the  broad  objectives  of  the  PPP  of  the  CARES  Act.  The
certification described above does not contain any objective criteria and is subject to interpretation. On April 23, 2020, the SBA issued guidance stating that it is unlikely that a
public company with substantial market value and access to capital markets will be able to make the required certification in good faith. The lack of clarity regarding loan
eligibility under the PPP has resulted in significant media coverage and controversy with respect to public companies applying for and receiving loans. If, despite our good-faith
belief that given our company’s circumstances we satisfied all eligible requirements for the PPP Loan, we are later determined to have violated any of the laws or governmental
regulations that apply to us in connection with the PPP Loan, such as the False Claims Act, or it is otherwise determined that we were ineligible to receive the PPP Loan, we
may be subject to penalties, including significant civil, criminal and administrative penalties and could be required to repay the PPP Loan in its entirety. In addition, receipt of a
PPP Loan may result in adverse publicity and damage to reputation, and a review or audit by the SBA or other government entity or claims under the False Claims Act could
consume  significant  financial  and  management  resources.  Any  of  these  events  could  have  a  material  adverse  effect  on  our  business,  results  of  operations  and  financial

Our business has been, and may in the future be, adversely affected by the effects of health epidemics, including the recent COVID-19 pandemic, in regions where we or
third parties on which we rely have clinical trial sites or other business operations In addition, if COVID-19 continues to be a worldwide pandemic, it could materially
affect our operations.

Our  business  has  been,  and  may  continue  to  be,  adversely  affected  by  health  epidemics,  including  the  COVID-19  pandemic,  in  regions  where  we  have  significant
manufacturing facilities, concentrations of clinical trial sites, or other business operations.

As  a  result  of  the  COVID-19  outbreak,  we  have  implemented  limitations  on  our  operations,  including  a  work-from-home  policy,  and  could  face  further  limitations  in  our
operations in the future. There is a risk that countries or regions may be less effective at containing COVID-19 than others, or it may be more difficult to contain if the outbreak
reaches a larger population or broader geography, in which case the risks described herein could be elevated significantly.

In  particular,  our  future  clinical  trials  may  be  affected  by  the  COVID-19  outbreak  or  other  future  health  epidemics.  Site  initiation,  patient  enrollment,  distribution  of  drug
product candidates, study monitoring, and data collection may be delayed due to changes in hospital policies, local regulations, and/or prioritization of hospital resources toward
the  COVID-19  outbreak  or  other  future  health  epidemics.  If  COVID-19  continues  to  spread  or  there  are  similar  health  epidemics  in  the  future,  some  patients  and  clinical
investigators may not be able to comply with clinical trial protocols. For example, quarantines may impede patient movement, affect sponsor access to study sites, or interrupt
healthcare services, and we may be required to delay patient enrollment or unable to obtain patient data as a result.

In addition, third party manufacturing of our product and product candidates and suppliers of the materials used in the production of our product candidates may be impacted by
restrictions  resulting  from  the  COVID-19  outbreak  or  other  future  health  epidemics  which  may  disrupt  our  supply  chain  or  limit  our  ability  to  manufacture  drug  product
candidates for our clinical trials.

The ultimate impact of the COVID-19 outbreak or a similar future health epidemic is highly uncertain and subject to change. We do not yet know the full extent of potential
delays  or  impacts  on  our  business,  our  clinical  trials,  healthcare  systems  or  the  global  economy  as  a  whole.  However,  these  effects  could  have  a  material  impact  on  our
operations, and we will continue to monitor the COVID-19 situation closely.

Our operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

We commenced active operations in 2006, and our operations to date have been largely focused on raising capital, identifying potential product candidates, broadening our
expertise  in  the  development  of  our  prodrugs,  undertaking  preclinical  studies  and  conducting  clinical  trials.  To  date,  we  have  only  two  products  approved  by  the  FDA,
AZSTARYS, a once-daily product for the treatment of ADHD in patients age six years and older, and APADAZ for the short-term (no more than 14 days) management of acute
pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. We have not yet demonstrated an ability to manufacture a prodrug on a
commercial scale, or arrange for a third party to do so, or conduct sales and marketing activities necessary for successful commercialization. Further, we cannot guarantee that
that Commave will be able to successfully commercialize AZSTARYS or any of our other product candidates subject to the KP415 License Agreement, if approved, that KVK
will be able to successfully commercialize APADAZ, or that we will ever receive any payments under the KP415 License Agreement or the APADAZ License Agreement from
commercial sales of AZSTARYS, APADAZ, or any of our other product candidates, if approved. 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 operating history.

We may encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors in achieving our business objectives. We will need to transition
at some point from a company with a research and development focus to a company capable of supporting commercial activities. We may not be successful in such a transition.

We expect our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which
are beyond our control. Accordingly, you should not rely upon the results of any quarterly or annual periods as indications of future operating performance.

Risks Related to Our Dependence on Third Parties

We rely on and expect to continue to rely on third parties to conduct our clinical trials for our product candidates, and those third parties may not perform satisfactorily,
including failing to meet deadlines for the completion of such trials.

We have engaged and expect to continue to engage CROs for our planned clinical trials of our product candidates. We rely on and expect to continue to rely on CROs, as well
as other third parties, such as clinical data management organizations, medical institutions and clinical investigators, to conduct those clinical trials. Agreements with such third
parties might terminate for a variety of reasons, including a failure to perform by the third parties. If we need to enter into alternative arrangements, our drug development
activities would be delayed.

Our reliance on these third parties for research and development activities reduces our control over these activities but does not relieve us of our responsibilities. For example,
we 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 regulatory 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. Regulatory authorities
enforce these GCPs through periodic inspections of trial sponsors, investigators and trial sites. We also are required to register specified ongoing clinical trials and post the
results of completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes. In addition, we must conduct our clinical trials with
product produced under cGMP requirements. Failure to comply with these regulations may require us to repeat preclinical studies and clinical trials, which would delay the
regulatory approval process. Failure to comply with the applicable requirements related to clinical investigations by us, our CROs or clinical trial sites can also result in clinical
holds and termination of clinical trials, debarment, FDA refusal to approve applications based on the clinical data, warning letters, withdrawal of marketing approval if the
product has already been approved, fines and other monetary penalties, delays, adverse publicity and civil and criminal sanctions, among other consequences.

Furthermore, these third parties may also have relationships with other entities, some of which may be our competitors. If these third parties do not successfully carry out their
contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or
may  be  delayed  in  obtaining,  marketing  approvals  for  our  product  candidates  and  will  not  be  able  to,  or  may  be  delayed  in  our  efforts  to,  successfully  commercialize  our
product candidates.

In  addition,  investigators  for  our  clinical  trials  may  serve  as  scientific  advisors  or  consultants  to  us  from  time  to  time  and  may  receive  cash  or  equity  compensation  in
connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or the FDA concludes that the financial
relationship may have affected the interpretation of the study, the integrity of the data generated at the applicable clinical trial site may be questioned and the utility of the
clinical trial itself may be jeopardized, which could result in the delay or rejection of any NDA we submit by the FDA. Any such delay or rejection could prevent us from
commercializing our product candidates. Further, our arrangements with investigators are also subject to scrutiny under other health care regulatory laws, such as the Anti-
Kickback Statute.

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

If the third parties with whom we contract do not successfully carry out their contractual duties or obligations or meet expected deadlines or if the quality or accuracy of the
clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our clinical trials may be extended,
delayed or terminated, we may need to conduct additional trials, and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates.
As a result, the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenue could be delayed. To the extent
we are unable to successfully identify and manage the performance of third-party service providers in the future, our business may be adversely affected.

44

 
 
 
 
 
 
 
 
 
 
We contract with third parties for the manufacture of our partnered product and product candidates that utilize benzhydrocodone and SDX as the API used in our clinical
trials and with a sole source supplier for the manufacture of bulk quantities of benzhydrocodone and SDX used in the partnered product and product candidates that utilize
these moieties as the API and we expect to continue to do so. This reliance on third-party manufacturers increases the risk that we will not have sufficient quantities of
benzhydrocodone and SDX, or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts.

We  do  not  have  any  manufacturing  facilities.  We  procure  the  bulk  drug  substances  for  AZSTARYS,  KP484,  APADAZ  and  KP879  from  sole-source,  third-party
manufacturers and the partnered product and product candidates that utilize these moieties as the API used in our clinical trials from other third parties. We anticipate we will
continue to do so for the foreseeable future. We also expect to continue to rely on third parties as we proceed with preclinical and clinical testing of our product candidates, as
well as for commercial manufacture of AZSTARYS, APADAZ, or any of our other product candidates should they receive marketing approval. This reliance on third parties
increases  the  risk  that  we  will  not  have  sufficient  quantities  of  benzhydrocodone,  SDX,  other  bulk  drug  substances  or  our  partnered  product  or  product  candidates,  or  such
quantities at an acceptable cost or quality, which could delay, prevent or impair our ability to timely conduct our clinical trials or our other development or commercialization
efforts.

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

  ● reliance on the third party for FDA and DEA regulatory compliance and quality assurance;

  ● the possible misappropriation of our proprietary information, including our trade secrets and know-how;

  ● disruption and costs associated with changing suppliers, including additional regulatory filings;

  ● the possible breach, termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us;

  ● a delay or inability to procure or expand sufficient manufacturing capacity; 

  ● manufacturing and product quality issues related to scale-up of manufacturing;

  ● costs and validation of new equipment and facilities required for scale-up;

  ● the inability to negotiate manufacturing agreements with third parties under commercially reasonable terms;

  ● termination or nonrenewal of manufacturing agreements with third parties in a manner or at a time that is costly or damaging to us;

  ● the reliance on a limited number of sources, and in some cases, single sources for product components, such that if we are unable to secure a sufficient supply of these
product components, we will be unable to manufacture and sell our product candidates in a timely fashion, in sufficient quantities or under acceptable terms; and

  ● carrier disruptions or increased costs that are beyond our control.

Any of these events could lead to clinical trial delays, failure to obtain regulatory approval or impact our ability to successfully commercialize our products. Some of these
events could be the basis for FDA action, including injunction, recall, seizure or total or partial suspension of production.

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The facilities used by our contract manufacturers to manufacture AZSTARYS, APADAZ, and any of our other product candidates must be approved by the FDA pursuant
to inspections that will be conducted after we submit our marketing application to the FDA, and these facilities could fail to obtain FDA approval.

We do not, other than through our contractual arrangements, control the manufacturing process of AZSTARYS, APADAZ, or any of our other product candidates, and we are
completely dependent on, our contract manufacturing partners for compliance with cGMP requirements and for manufacture of both active drug substances and finished drug
products. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or other
regulatory  authorities,  we  will  not  be  able  to  secure  and  maintain  regulatory  approval  for  their  manufacturing  facilities.  In  addition,  other  than  through  our  contractual
agreements, 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  manufacturing  of  AZSTARYS, APADAZ  or  any  of  our  other  product  candidates  or  if  it
withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain marketing
approval for or market AZSTARYS, APADAZ, or any of our other product candidates, if approved.

Further, for AZSTARYS, APADAZ and any of our other product candidates, if approved, our suppliers will be subject to regulatory requirements, covering manufacturing,
testing, quality control and record keeping relating to AZSTARYS, APADAZ or any of our other product candidates, if approved, and subject to ongoing inspections by the
regulatory agencies. Failure by any of our suppliers to comply with applicable regulations may result in long delays and interruptions to our manufacturing capacity while we
seek to secure another supplier that meets all regulatory requirements, as well as market disruption related to any necessary recalls or other corrective actions.

Third-party manufacturers may not be able to comply with current 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 warning letters, clinical holds or termination of
clinical  trials,  fines,  injunctions,  restitution,  disgorgement,  civil  penalties,  delays,  suspension  or  withdrawal  of  approvals  or  other  permits,  FDA  refusal  to  approve  pending
applications, product detentions, FDA or DEA consent decrees placing significant restrictions on or suspending manufacturing and distribution operations, debarment, refusal to
allow import or export, product detentions, adverse publicity, dear-health-care-provider letters or other warnings, license revocation, seizures or recalls of product candidates,
operating restrictions, refusal of government contracts or future orders under existing contracts and civil and criminal liability, including False Claims Act liability, exclusion
from participation in federal health care programs, and corporate integrity agreements among other consequences, any of which could significantly and adversely affect supplies
of our prodrugs.

Our product candidates and any prodrugs that we may develop may compete with other product candidates and drugs for access to manufacturing facilities, and we may be
unable to obtain access to these facilities on favorable terms.

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. We do not currently have arrangements in place for redundant supply or a second
source for AZSTARYS, KP484 or KP879 bulk drug substance. If our current contract manufacturer for AZSTARYS, KP484 or KP879 bulk drug substance cannot perform as
agreed, we may be required to replace such manufacturer and we may incur added costs and delays in identifying and qualifying any such replacement.

46

 
 
 
 
 
 
 
 
We have entered into collaborations with Commave, to develop, manufacture and commercialize AZSTARYS and KP484 worldwide, and KVK, for the commercialization of
APADAZ in the United States. In addition, we may seek collaborations with third parties for the development or commercialization of our other product candidates, or in
other territories. If those collaborations are not successful, we may not be able to capitalize on the market potential of AZSTARYS, APADAZ, or any of our other product
candidates, if approved.

We  entered  into  the  KP415  License  Agreement  with  Commave  pursuant  to  which  we  granted  an  exclusive,  worldwide  license  to  Commave  to  develop,  manufacture  and
commercialize AZSTARYS and KP484. We cannot guarantee that the K415 License Agreement with Commave will be successful or that we will receive any future payments
under the KP415 License Agreement. For instance, Commave has the option to terminate the KP415 License Agreement, in its entirety or on a product-by-product and country-
by-country basis, at their convenience either (i) prior to the first regulatory approval of a product upon sixty days prior written notice or (ii) subsequent to the first regulatory
approval of a product upon one hundred twenty days prior written notice. Further, even if Commave does not terminate the KP415 License Agreement, we cannot guarantee
that we will receive any additional milestone or royalty payments under the KP415 License Agreement. In addition, under the KP415 License Agreement, we have limited
control over the amount and timing of resources that Commave will dedicate to the development, manufacturing or commercialization of AZSTARYS and KP484, and we may
not  always  agree  with  Commave’s  efforts.  Our  ability  to  generate  revenue  under  the  KP415  License  Agreement  will  depend,  in  part,  on  Commave’s  ability  to  successfully
perform the functions assigned to it under the KP415 License Agreement.

In addition, we have entered into the APADAZ License Agreement with KVK pursuant to which we granted an exclusive license to KVK to commercialize APADAZ in the
United States. We cannot guarantee that our collaboration with KVK will be successful or that we will ever receive any payments under the APADAZ License Agreement. For
instance,  if  the  Initial  Adoption  Milestone  is  not  achieved,  KVK  may  terminate  the  APADAZ  License  Agreement  without  making  any  payments  to  us.  Further,  even  if  the
Initial Adoption Milestone under the APADAZ License Agreement is achieved, we cannot guarantee that we will receive any additional milestone or royalty payments under
the APADAZ License Agreement. Further, under the APADAZ License Agreement, we have limited control over the amount and timing of resources that KVK will dedicate to
the  commercialization  of  APADAZ,  and  we  may  not  always  agree  with  KVK’s  commercialization  efforts.  Our  ability  to  generate  revenue  under  the  APADAZ  License
Agreement will depend on KVK’s ability to successfully perform the functions assigned to it under the APADAZ License Agreement. The commercialization strategy under the
APADAZ  License  Agreement  is  novel  and  untested,  and,  even  if  successful  we  expect  that  the  pricing  for  any  sales  of  APADAZ  will  be  at  or  near  the  prices  of  currently
available generic equivalent drugs. As a result, even if KVK does successfully perform its functions under the APADAZ License Agreement, we cannot guarantee that there
will be sufficient market demand for APADAZ for us to receive any revenue under the APADAZ License Agreement.

We may also seek additional third-party collaborators for the commercialization of APADAZ outside of the United States or for the development or commercialization of any of
our other product candidates, which are not subject to the KP415 License Agreement, or those that are subject to the KP415 License Agreement but the option is not exercised
by  Commave.  In  such  cases,  our  likely  collaborators  would  include  large  and  mid-size  pharmaceutical  companies,  regional,  national  and  international  pharmaceutical
companies and biotechnology companies. If we do enter into any such collaboration arrangements with any third parties, we will likely have limited control over the amount
and timing of resources that our collaborators dedicate to the development or commercialization of AZSTARYS or APADAZ outside of the United States or any of our other
product candidates. Our ability to generate revenue from these arrangements will depend on our collaborators’ abilities to successfully perform the functions assigned to them in
these arrangements.

47

 
 
 
 
 
 
Our collaborations with Commave and KVK, or combined the Collaborators, pose the following risks to us:

  ● The Collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations;

  ● The Collaborators may not perform their obligations as expected;

  ● The Collaborators may not pursue commercialization of AZSTARYS, APADAZ, or any of our other product candidates covered under the KP415 License Agreement, if
approved, or may elect not to continue or renew commercialization programs based on post-approval clinical trial results, changes in the Collaborator's strategic focus or
available funding, or external factors, such as an acquisition, that divert resources or create competing priorities;

  ● The Collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with AZSTARYS, APADAZ, or any of our
other  products  covered  under  the  KP415  License  Agreement,  as  applicable,  if  the  Collaborators  believe  that  competitive  products  are  more  likely  to  be  successfully
developed or can be commercialized under terms that are more economically attractive than ours;

  ● AZSTARYS, APADAZ, and any of our other products covered under the KP415 License Agreement may be viewed by the Collaborators as competitive with their own
product candidates or products, which may cause the Collaborators to cease to devote resources to the commercialization of AZSTARYS, APADAZ, or any of our other
products covered under the KP415 License Agreement, if approved;

  ● The Collaborators may not commit sufficient resources to the development, marketing and distribution of AZSTARYS, APADAZ, and any of our other products covered

under the KP415 License Agreement, as applicable;

  ● disagreements  with  the  Collaborators,  including  disagreements  over  proprietary  rights,  contract  interpretation  or  the  preferred  course  of  development
or commercialization, might cause delays or termination of the development or commercialization of AZSTARYS, APADAZ, or any of our other products covered under
the  KP415  License  Agreement,  as  applicable,  might  lead  to  additional  responsibilities  for  us  with  respect  to  AZSTARYS,  APADAZ,  or  any  of  our  other  products
covered under the KP415 License Agreement, or might result in litigation or arbitration, any of which would be time-consuming and expensive;

  ● The Collaborators 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;

  ● The Collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability; and

  ● the  license  agreements  may  be  terminated  by  the  Collaborators  under  specified  circumstances  and,  if  terminated,  we  could  be  required  to  raise  additional  capital  to

pursue further development or commercialization of AZSTARYS, APADAZ, or any of our other products covered under the KP415 License Agreement.

If we enter into any future collaborations we will face similar risks with any future collaborators as well.

The KP415 License Agreement, the APADAZ License Agreement, and any other licensing or collaboration agreements we may enter into may not lead to commercialization of
AZSTARYS, commercialization of APADAZ, or development of KP484, KP879 or any of our other product candidates in the most efficient manner or at all. If Commave
or KVK or a future collaborator 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.

48

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we are not able to establish collaborations for our product candidates, we may have to alter our development and commercialization plans.

Our  prodrug  development  programs  and  the  potential  commercialization  of  our  product  candidates,  if  approved,  will  require  substantial  additional  capital.  For  our  product
candidates, which are not subject to the terms of the KP415 License Agreement or the APADAZ License Agreement, we may need to collaborate with pharmaceutical and
biotechnology companies for the development and potential commercialization of those product candidates.

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our
assessment  of  the  collaborator’s  resources  and  expertise,  the  terms  and  conditions  of  the  proposed  collaboration  and  the  proposed  collaborator’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 product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing
products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the
challenge, and industry and market conditions generally.

The  collaborator  may  also  consider  alternative  product  candidates  or  technologies  for  similar  indications  that  may  be  available  to  collaborate  on  and  whether  such  a
collaboration could be more attractive than the one with us for our product candidate.

Collaborations 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 collaborators.

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of product
candidates,  reduce  or  delay  one  or  more  of  our  development  programs,  delay  potential  commercialization  of  our  product  candidates  or  reduce  the  scope  of  any  sales  or
marketing  activities  of  our  product  candidates,  or  increase  our  expenditures  and  undertake  development  or  commercialization  activities  at  our  own  expense  of  our  product
candidate. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be
available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring our product candidates to
market and generate product revenue.

Provisions in our agreements with Aquestive and Commave may inhibit our ability to enter into future collaborations with third parties.

We are party to a termination agreement with Aquestive Therapeutics, or Aquestive, that may limit the value of any sale, license or commercialization of AZSTARYS, KP484
or KP879. Under this termination agreement, Aquestive has the right to receive a royalty amount equal to 10% of any value generated by AZSTARYS, KP484 or KP879, and
any product candidates which contain SDX, including royalty payments on any license of AZSTARYS, KP484 or KP879, the sale of AZSTARYS, KP484 or KP879 to a third
party or the commercialization of AZSTARYS, KP484 or KP879. As part of the KP415 License Agreement, we paid Aquestive a royalty equal to 10% of the license upfront
payment we received in the third quarter of 2019 and the regulatory milestone payment we received in the second quarter of 2020.

We also granted to Commave a right of first refusal to acquire, license or commercialize any Additional Product Candidate, with such right of first refusal expiring upon the
acceptance  of  a  new  drug  application  for  such  Additional  Product  Candidate.  We  also  granted  Commave  a  right  of  first  negotiation  and  a  right  of  first  refusal,  subject  to
specified exceptions, for any assignment of our rights under the KP415 License Agreement. We cannot predict if these obligations will limit the value we may receive from any
future sale or license of any Additional Product Candidate.

49

 
 
 
 
 
 
 
 
 
 
 
Risks Related to Our Intellectual Property

If we are unable to obtain and maintain trade secret protection or patent protection for our technology, AZSTARYS, APADAZ, or our other product 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 commercialize our technology, AZSTARYS, APADAZ, or our other product candidates, if approved, may be impaired.

Our success depends in large part on our ability to obtain and maintain trade secret protection of our proprietary LAT technology as well as patent protection in the United
States  and  other  countries  with  respect  to  AZSTARYS,  APADAZ,  and  any  of  our  other  product  candidates.  We  seek  to  protect  our  proprietary  position  by  filing  patent
applications in the United States and abroad related to our product technology and product candidates. As part of the KP415 License Agreement, Commave, obtained from us
an  exclusive,  worldwide  license  to  certain  patents  that  cover  AZSTARYS  and  KP484.    In  addition,  as  part  of  the  APADAZ  License  Agreement,  KVK  obtained  from  us  an
exclusive license to certain patents that cover APADAZ. 

The patent prosecution process is expensive and time-consuming, 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 research and 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 by us.

Further, we may also not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the rights to patents, licensed from third parties to
us. Therefore, any such patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. If such licensors or licensees
fail to maintain such patents, or lose rights to those patents, the rights we have in- or out-licensed may be reduced or eliminated.

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 visa-versa. For example,
European patent law restricts the patentability of methods of treatment of the human body more than United States law. Publications of discoveries in the scientific literature
often lag behind the actual discoveries, and utility, or equivalent, patent applications in the United States and other jurisdictions are typically, for example, not published until 18
months after the filing date of such patent applications, or in some cases not at all. Therefore, we cannot know with certainty whether we were the first to make and/or use the
inventions claimed in our owned or licensed patents or pending patent applications, or that we were the first to file for patent protection of such inventions. As a result, the
issuance, scope, priority, 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 product candidates, in whole or in part, or which effectively prevent others from commercializing competitive technologies and drugs.
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.

50

 
 
 
 
 
 
 
 
Our patent position is subject to numerous additional risks, including the following:

  ● we may fail to seek patent protection for inventions that are important to our success;

  ● our pending patent applications may not result in issued patents;

  ● we cannot be certain that we are the first to invent the inventions covered by pending patent applications or that we are the first to file such applications and, if we are

not, we may be subject to priority disputes or lose rights;

  ● we may be required to disclaim part or all of the term of certain patents or all of the term of certain patent applications;

  ● we  may  not  be  able  to  acquire  patent  term  extensions  of  certain  patents,  domestic  or  foreign,  due  to  regulatory  delays,  among  others,  which  may  affect  the  term  of

enforceability of such patents over time;

  ● we may file patent applications but have claims restricted or we may not be able to supply sufficient data to support our claims and, as a result, may not obtain the

original claims desired or we may receive restricted claims; alternatively, it is possible that we may not receive any patent protection from an application;

  ● even if our owned and licensed patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, and may not be of

sufficient scope or strength to provide us with any commercial advantage;

  ● our  competitors  may  be  able  to  design  around  our  owned  or  licensed  patents  by  developing  similar  or  alternative  technologies  or  drugs  without  infringing  on  our

intellectual property rights;

  ● we  could  inadvertently  abandon  a  patent  or  patent  application,  resulting  in  the  loss  of  protection  of  intellectual  property  rights  in  a  particular  country,  and  we,  our
collaborators  or  our  patent  counsel  may  take  action  resulting  in  a  patent  or  patent  application  becoming  abandoned  which  may  not  be  able  to  be  reinstated  or  if
reinstated, may suffer patent term adjustments or loss;

  ● the claims of our issued patents or patent applications when issued may not cover our product candidates;

  ● no assurance can be given that our patents would be declared by a court, domestic or foreign, to be valid or enforceable or that a competitor’s technology or product
would be found by a court, domestic or foreign, to infringe our patents and our patents or patent applications may be challenged by third parties in patent litigation,
domestic or foreign, or in proceedings before the United States Patent and Trademark Office, or the USPTO, or its foreign counterparts, and may ultimately be declared
invalid or unenforceable or narrowed in scope; 

  ● there may be prior art of which we are not aware that may affect the validity or enforceability of a patent claim and there may be prior art of which we are aware, but

which we do not believe affects the validity or enforceability of a claim, which may, nonetheless, ultimately be found to affect the validity or enforceability of a claim;

  ● third parties may develop products that have the same or similar effect as our products without infringing our patents;

  ● third parties may intentionally circumvent our patents by means of alternate designs or processes or file applications or be granted patents that would block or hurt our

efforts;

  ● there may be dominating or intervening patents relevant to our product candidates of which we are not aware;

  ● obtaining regulatory approval for pharmaceutical products is a lengthy and complex process, and as a result, any patents covering our product candidates may expire

before or shortly after such product candidates are approved and commercialized;

  ● the patent and patent enforcement laws of some foreign jurisdictions do not protect intellectual property rights to the same extent as laws in the United States, and many

companies have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions; and

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

Any  of  these  factors  could  hurt  our  ability  to  gain  full  patent  protection  for  our  products.  Registered  trademarks  and  trademark  applications  in  the  United  States  and  other
countries are subject to similar risks as described above for patents and patent applications, in addition to the risks described below.

Further,  a  third  party  may  misappropriate  or  reverse  engineer  our  proprietary  LAT  technology,  which  could  limit  our  ability  to  stop  others  from  using  or  commercializing
similar  or  identical  technology  and  resultant  product  candidates,  product  technology  or  prodrugs,  or  limit  the  duration  of  the  trade  secret  protection  of  our  proprietary  LAT
technology.

Moreover, we may be subject to a third-party pre-issuance submission of prior art to the USPTO, or become involved in opposition, litigation, nullity, 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 drugs and compete directly with us,
without payment to us or result in our inability to manufacture or commercialize drugs without infringing third-party patent rights. In addition, if the breadth or strength of
protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to seek patent protection or to license, develop
or commercialize current or future product candidates.

In addition, the issuance of a patent is not conclusive as to its inventorship, ownership, scope, priority, validity or enforceability, and our owned and licensed patents may be
challenged in the courts, patent offices and tribunals in the United States and abroad. Such challenges may result in loss of exclusivity or in patent claims being narrowed,
invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and drugs, or
limit the duration of the patent protection of our product technology, product candidates and prodrugs.

Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued
patents.

On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to
U.S. patent law. These include provisions that affect the way patent applications are prosecuted in the United States, redefine prior art and may also affect patent litigation. The
USPTO recently developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated
with the Leahy-Smith Act, and in particular, the first-to-file provisions, only became effective on March 16, 2013.

The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense
of our issued patents. For instance, the Leahy-Smith Act established the inter partes review and post grant review procedures that has lowered the burden of proof for invalidity
challenges to issued patents and limited the ability to amend patent claims in response to such challenges. In addition, patent reform legislation may pass in the future that could
lead to additional uncertainties and increased costs surrounding the prosecution, enforcement and defense of our owned and licensed patents and/or patent applications.

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

Competitors may infringe our issued patents or other intellectual property. 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 those parties to assert counterclaims against us alleging that we infringe
their  intellectual  property  rights.  In  addition,  in  a  patent  infringement  proceeding,  a  court  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 or its prior
use  by  a  third  party.  An  adverse  result  in  any  litigation  proceeding  could  put  one  or  more  of  our  patents  at  risk  of  being  invalidated  or  interpreted  narrowly,  which  would
undermine our competitive position.

Third  parties  may  initiate  legal  proceedings  alleging  that  we  are  infringing  their  intellectual  property  rights,  the  outcome  of  which  would  be  uncertain  and  could
significantly harm our business.

Our commercial success depends upon our ability, and the ability of any collaborators, to develop, manufacture, market and sell our product candidates and use our proprietary
technologies without infringing the proprietary rights of third parties. There is considerable intellectual property litigation in the biotechnology and pharmaceutical industries. In
particular, we are focused on developing product candidates based on widely used therapeutic agents or drugs, many of which may be protected by proprietary rights of third
parties.

Although we seek to develop proprietary prodrug formulations that do not infringe the intellectual property rights of others, we may become party to, or threatened with, future
adversarial proceedings or litigation, domestic or foreign, regarding intellectual property rights with respect to our prodrugs or other aspects of our technology, including, for
example, interference or derivation proceedings before the USPTO. Third parties may assert infringement claims against us based on existing patents or patents that may be
granted in the future.

If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue developing and marketing our
technology and drugs. However, we may not be able to obtain any required license on commercially reasonable terms, or at all. Even if we were able to obtain a license, it could
be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the
infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully
infringed a patent. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some or all of our business operations.

Competing  products  may  also  be  sold  in  other  countries  in  which  our  patent  coverage  might  not  exist  or  be  as  strong.  If  we  lose  a  foreign  patent  lawsuit  alleging  our
infringement of a competitor’s patent, we could be prevented from marketing our products in one or more foreign countries. As a result, our ability to grow our business and
compete in the market may be harmed.

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. If securities analysts or investors perceive
these  results  to  be  negative,  it  could  hurt  the  price  of  our  common  stock.  Such  litigation  or  proceedings  could  substantially  increase  our  operating  losses  and  reduce  the
resources available for development activities or any future sales, marketing or distribution 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. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our ability to compete in the
marketplace.

53

 
 
 
 
 
 
 
 
 
 
 
 
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 rights, including patent rights, which are important or necessary to the development of our product candidates. It may be necessary
for us to use the patented or proprietary technology of third parties to commercialize our product candidates, in which case we would be required to obtain a license from these
third parties. Such a license may not be available on commercially reasonable terms, or at all, and we could be forced to accept unfavorable contractual terms. If we are unable
to obtain such licenses on commercially reasonable terms, our business could be harmed.

If we or our third-party licensors fail to comply with our obligations in our intellectual property licenses and funding arrangements with third parties, we could lose rights
that are important to our business.

We are currently party to license agreements for technologies that we anticipate using in our product development activities. In the future, we may become party to licenses that
are important for product development and commercialization. If we or our third-party licensors fail to comply with the obligations under current or future license and funding
agreements, our counterparties may have the right to terminate these agreements, we may be forced to terminate these agreement or we may no longer effectively rely on any
licenses to us under these agreements, in which event we might not be able to develop, manufacture or market any product or utilize any technology that is covered by these
agreements or may face other penalties under the agreements. Such an occurrence could materially and adversely affect the value of a product candidate being developed under
any such agreement or could restrict our drug discovery activities. Termination of these agreements or reduction or elimination of our rights under these agreements may result
in  our  having  to  negotiate  new  or  reinstated  agreements  with  less  favorable  terms  or  cause  us  to  lose  our  rights  under  these  agreements,  including  our  rights  to  important
intellectual property or technology.

We may be required to reduce the scope of our intellectual property due to third-party intellectual property claims.

Our competitors may have filed, and may in the future file, patent applications covering technology similar to ours. Any such patent application may have priority over our
patent applications, which could further require us to obtain rights to issued patents covering such technologies. If another party has filed a U.S. patent application on inventions
similar  to  ours  that  claims  priority  to  an  application  filed  prior  to  March  16,  2013,  we  may  have  to  participate  in  an  interference  proceeding  declared  by  the  USPTO  to
determine  priority  of  invention  in  the  United  States.  The  costs  of  these  proceedings  could  be  substantial,  and  it  is  possible  that  such  efforts  would  be  unsuccessful  if,
unbeknownst to us, the other party had independently arrived at the same or similar invention prior to our own invention, resulting in a loss of our U.S. patent position with
respect to such inventions. In addition, changes enacted on March 16, 2013, to the U.S. patent laws under the Leahy-Smith Act resulted in the United States changing from a
“first to invent” country to a “first to file” country. As a result, we may lose the ability to obtain a patent if another party files with the USPTO first and could become involved
in proceedings before the USPTO to resolve disputes related to inventorship. We may also become involved in similar proceedings in other jurisdictions.

Furthermore, recent changes in U.S. patent law under the Leahy-Smith Act allows for post-issuance challenges to U.S. patents, including ex parte re-examinations, inter partes
reviews and post-grant reviews. There is significant uncertainty as to how the new laws will be applied. If our U.S. patents are challenged using such procedures, we may not
prevail, possibly resulting in altered or diminished claim scope or loss of patent rights altogether. Similarly, some countries, notably Europe, also have post-grant opposition
proceedings or nullify proceedings that can result in changes in scope or cancellation of patent claims.

We may be subject to claims by third parties asserting that we or our employees have misappropriated their intellectual property or claiming ownership of what we regard
as our own intellectual property.

Many  of  our  employees  were  previously  employed  at  other  biotechnology  or  pharmaceutical  companies.  Although  we  try  to  ensure  that  our  employees  do  not  use  the
proprietary information, show-how or know-how of others in their work for us, we may be subject to claims that these employees or we have inadvertently or otherwise used or
disclosed  intellectual  property,  including  trade  secrets  or  other  proprietary  information,  of  any  such  employee’s  former  employer.  For  example,  in  March  2012,  we  settled
litigation regarding similar matters with Shire Pharmaceuticals, LLC, or Shire. We may also in the future be subject to claims that we have caused an employee to breach the
terms of his or her non-competition or non-solicitation agreement. Litigation may be necessary to defend against these potential 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 fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. A court could
prohibit us from using technologies or features that are essential to our products, if such technologies or features are found to incorporate or be derived from the trade secrets or
other proprietary information of the former employers. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and
could  be  a  distraction  to  management.  In  addition,  any  litigation  or  threat  thereof  may  adversely  affect  our  ability  to  hire  employees  or  contract  with  independent  service
providers. Moreover, a loss of key personnel or their work product could hamper or prevent our ability to commercialize our products.

54

 
 
 
 
 
 
 
 
 
 
 
 
 
Any trademarks we 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 product candidates that are approved for marketing from the products of our competitors. We have registered
trademarks for LAT and KemPharm. In addition, we have solicited and applied for trademarks for the KemPharm logo and several potential trade names and logos for future
product candidates. Third parties may oppose or attempt to cancel our trademark applications or trademarks, or otherwise challenge our use of the trademarks. If our trademarks
are successfully challenged, we could be forced to rebrand our products, 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.

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

In addition to seeking patent and trademark protection for our product candidates, we also rely on trade secrets, including unpatented show-how, 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.

Monitoring  unauthorized  uses  and  disclosures  of  our  intellectual  property,  including  our  trade  secrets,  is  difficult,  and  we  do  not  know  whether  the  steps  we  have  taken  to
protect our intellectual property will be effective. In addition, we may not be able to obtain adequate remedies for any 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.

Moreover, our competitors may independently develop or reverse engineer knowledge, methods, show-how and know-how equivalent to our trade secrets. Competitors could
purchase  our  products  and  replicate  some  or  all  of  the  competitive  advantages  we  derive  from  our  development  efforts  for  technologies  on  which  we  do  not  have  patent
protection. 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 such trade secrets, 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.

Outside of the U.S. 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 inventions to save costs. We may be forced to abandon or return the rights to specific patents due to a
lack of financial resources.

Risks Related to the Commercialization of Our Partnered Products and Product Candidates

If  we  are  unable  to  establish  sales,  marketing  and  distribution  capabilities  for  our  product  candidates,  if  approved,  we  may  not  be  successful  in  commercializing  any
approved product candidate in the United States.

We have only a limited sales and marketing infrastructure and have no experience in the sale, marketing or distribution of pharmaceutical products. To achieve commercial
success  for  any  product  candidate  for  which  we  may  obtain  marketing  approval  in  the  United  States,  we  will  need  to  enter  into  collaborations  with  one  or  more  parties  or
establish our own sales and marketing organization. While we entered into the  KP415 License Agreement to establish a collaboration for the commercialization of AZSTARYS
and  any  of  our  other  product  candidates  which  are  subject  to  such  agreement,  and  we  entered  into  the  APADAZ  License  Agreement  to  establish  a  collaboration  for  the
commercialization of APADAZ,  we may not choose to enter into a collaboration for any future approved product. Should we decide to establish our own sales, marketing and
distribution capabilities, we would encounter a number of risks. For example, recruiting and training a sales force is expensive and time consuming and could delay any product
launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we
would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our
sales and marketing personnel.

Factors that may inhibit our efforts to commercialize our product candidates on our own include:

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

  ● our inability to access government and commercial health plan formularies or secure preferred coverage and adequate reimbursement levels;

  ● the inability of sales personnel to obtain access to physicians or achieve adequate numbers of physicians to prescribe any future prodrug products;

● the lack of complementary drugs to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product

lines;

  ● liability for personnel, including sales personnel, failing to comply with applicable legal requirements; and

● costs associated with maintaining compliance with the FDA’s marketing and promotional requirements, including ongoing training and monitoring, as well as unforeseen

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

If we decide not to or are unable to establish our own sales, marketing and distribution capabilities and, instead, enter into arrangements with third parties to perform these
services, our product revenue and our profitability, if any, are likely to be lower than if we were to sell, market and distribute any product candidates that we develop ourselves.
For  instance,  under  the  KP415  License  Agreement  we  are  entitled  to  receive  quarterly,  tiered  royalty  payments  ranging  from  a  percentage  in  the  high  single  digits  to  mid-
twenties of Net Sales (as defined in the KP415 License Agreement) in the U.S. and a percentage in the low to mid-single digits of Net Sales in each country outside of the U.S.,
in each case subject to specified reductions under certain conditions as described in the KP415 License Agreement, as well as, sales milestones based on specified sales targets.
In addition, we may not be successful in entering into arrangements with third parties to sell, market and distribute our product candidates in the future, or may be unable to do
so on terms that are favorable to us. Further, under the APADAZ License Agreement, we and KVK will share the quarterly net profits of APADAZ by KVK in the United States
at specified tiered percentages, with the portion we receive ranging from 30% to 50% of net profits. As a result, we will be entitled to a smaller portion of the net profits of any
sales  of  APADAZ  in  the  United  States  than  if  we  had  decided  to  sell,  market  and  distribute  APADAZ  ourselves.  We  likely  will  have  little  control  over  such  third  parties,
including Commave and KVK, and any of them may fail to devote the necessary resources and attention to sell and market AZSTARYS, APADAZ, or any of our other product
candidates, if approved, effectively. Further, we may be liable for conduct of third parties, including Commave and KVK, acting on our behalf, including failure to comply with
legal  requirements  applicable  to  sales  and  marketing  of  our  product  or  product  candidates,  if  approved.  If  we  do  not  establish  sales,  marketing  and  distribution  capabilities
successfully,  either  on  our  own  or  in  collaboration  with  third  parties,  we  will  not  be  successful  in  commercializing  AZSTARYS,  APADAZ,  or  any  of  our  other  product
candidates, if approved.

AZSTARYS, APADAZ, or any of our other product candidates that may receive marketing approval, 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.

AZSTARYS,  APADAZ,  or  any  of  our  other  product  candidates  that  may  receive  marketing  approval,  may  fail  to  gain  sufficient  market  acceptance  by  physicians,  patients,
third-party payors and others in the medical community. Despite the fact that APADAZ is now nationally available, we cannot guarantee that it will receive significant, if any,
market acceptance in the United States. If AZSTARYS, APADAZ, or any of our other product candidates, if approved for commercial sale, do not achieve an adequate level of
market acceptance, they may not generate significant product revenue and we may not become profitable. For instance, under the APADAZ License Agreement, we are entitled
to milestone and royalty payments only if APADAZ sales in the United States are above specified levels. If APADAZ does not achieve an adequate level of market acceptance,
it is unlikely that sales will satisfy these thresholds and we may not be entitled to any payments under the APADAZ License Agreement. Additionally, the commercialization
strategy under the APADAZ License Agreement is novel and untested, and, even if successful we expect that the pricing for any sales of APADAZ will be at or near the prices
of currently available generic equivalent drugs. Accordingly, we expect that APADAZ will need to achieve broad market acceptance in order for this strategy to be successful.
The  degree  of  market  acceptance  of  AZSTARYS,  APADAZ,  or  any  of  our  other  product  candidates  if  approved  for  commercial  sale,  will  depend  on  a  number  of  factors,
including:

  ● the efficacy and potential advantages compared to alternative treatments, including less expensive generic treatments;

  ● the ability to obtain differentiating claims in the labels for most of our product candidates;

  ● our ability to offer our prodrug products for sale at competitive prices;

  ● the clinical indications for which our product candidates are approved;

  ● the convenience and ease of administration compared to alternative treatments;

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

  ● the cost of treatment in relation to alternative treatments;

● the steps that prescribers and dispensers must take, since AZSTARYS and APADAZ are, and we expect that most of our other product candidates likely going to be

considered controlled substances, as well as the perceived risks based upon their controlled substance status;

  ● the ability to manufacture our product in sufficient quantities and yields;

  ● the strength of marketing and distribution support;

  ● the availability of third-party coverage and adequate reimbursement or willingness of patients to pay out of pocket in the absence of third-party coverage;

  ● the prevalence and severity of any side effects;

  ● any potential unfavorable publicity;

  ● any restrictions on the use, sale or distribution of AZSTARYS, APADAZ, or any of our other product candidates, including through REMS; and

  ● any restrictions on the use of our prodrug products together with other medications.

We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully than we do.

Our industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. We will face competition and potential
competition from a number of sources, including pharmaceutical and biotechnology companies, specialty pharmaceutical companies, generic drug companies, drug delivery
companies and academic and research institutions. Our competitors may develop or market drugs that are more effective, more convenient, more widely used and less costly or
have a better safety profile than our products or product candidates and these competitors may also have significantly more resources than us and be more successful than us in
manufacturing and marketing their products.

AZSTARYS,  and,  if  approved,  KP484  will  compete  against  currently  marketed,  branded  and  generic  methylphenidate  products  for  the  treatment  of  ADHD.  Some  of  these
currently marketed products include Janssen’s CONCERTA, Tris Pharma’s QUILLIVANT XR and QUILLICHEW ER, Novartis’ RITALIN, FOCALIN and FOCALIN XR,
UCB’s  METADATE  CD,  Noven’s  DAYTRANA,  Neos  Therapeutics’  CONTEMPLA  XR-ODT,  Ironshore  Pharmaceuticals,  Inc.’s  JORNAY  PM  and  Adlon  Therapeutics’
ADHANSIA XR, in addition to multiple other branded and generic methylphenidate products. In addition, AZSTARYS and, if approved, KP484 will face potential competition
from any other methylphenidate products for the treatment of ADHD that are currently in or which may enter into clinical development.

Currently, there are no approved drugs in the United States for the treatment of SUD. If approved, KP879 will face potential competition from any products for the treatment of
SUD that are currently in or which may enter into clinical development.

Currently, there are no approved drugs in the United States for the treatment of IH. If approved, KP1077 could face competition from any products for the treatment of IH that
are currently in or which may enter into clinical development.

APADAZ competes against currently marketed, branded and generic IR hydrocodone/APAP combination products indicated for the short-term management of acute pain. In
addition, APADAZ will face potential competition from any IR or hydrocodone/APAP combination products for the short-term management of acute pain that are currently in
or may enter into clinical development.

Many of our potential competitors have substantially greater financial, technical and human resources than we do, as well as more experience in the development of product
candidates, obtaining FDA and other regulatory approvals of products and the commercialization of those products. Consequently, our competitors may develop products for
indications we are pursuing or may pursue in the future, and such competitors’ products may be more effective, better tolerated and less costly than our product candidates. Our
competitors  may  also  be  more  successful  in  manufacturing  and  marketing  their  products  than  we  are.  We  will  also  face  competition  in  recruiting  and  retaining  qualified
personnel and establishing clinical trial sites and patient enrollment in clinical trials.

Our competitors also may obtain FDA or other regulatory approval for their product candidates more rapidly than we may obtain approval for ours, which could result in our
competitors establishing a strong market position before we are able to enter the market. If the competitor’s product were similar to our product candidates, we may be required
to seek approval via alternative pathways, such as the ANDA, which is used for the development of generic drug products. We may also be blocked from product marketing by
periods of patent protection or regulatory exclusivity.

In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic drugs or giving drugs with
improved  attributes  sufficient  weight  in  a  comparative  clinical  cost  effectiveness  analysis.  For  some  of  the  indications  that  we  are  pursuing,  drugs  used  off-label  serve  as
cheaper  alternatives  to  our  product  candidates.  Their  lower  prices  could  result  in  significant  pricing  pressure,  even  if  our  product  candidates  are  otherwise  viewed  as  a
preferable therapy. Additional drugs may become available on a generic basis over the coming years.

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 and other early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies.

Consequently, our competitors may develop products for the treatment of ADHD, pain or for other indications we may pursue in the future, and such competitors’ products may
be more effective, better tolerated and less costly than our product candidates. Our competitors may also be more successful in manufacturing and marketing their products than
we are. We will also face competition in recruiting and retaining qualified personnel and establishing clinical trial sites and subject enrollment in clinical trials.

We may not be able to obtain either five-year FDA regulatory exclusivity as a new chemical entity or three-year FDA regulatory exclusivity.

The  FDA  provides  periods  of  regulatory  exclusivity  following  their  approval  of  an  NDA,  which  provide  the  holder  of  an  approved  NDA  limited  protection  from  new
competition in the marketplace for the innovation represented by its approved drug. Five-year exclusivity precludes approval of 505(b)(2) applications or ANDAs by delaying
the submission or approval of the application, while three-year exclusivity precludes the approval of the application. We intend to seek new chemical entity, or NCE, status
for any of our prodrug product candidates as appropriate. Five years of exclusivity are available to NCEs following the approval of an NDA by the FDA. An NCE is a drug that
contains  no  active  moiety  that  has  been  approved  by  the  FDA  in  any  other  NDA.  If  a  product  is  not  eligible  for  the  NCE  exclusivity,  it  may  be  eligible  for  three  years  of
exclusivity. Three-year exclusivity is available to the holder of an NDA, including a 505(b)(2) NDA, for a particular condition of approval, or change to a marketed product,
such as a new formulation for a previously approved product, if one or more new clinical trials, other than bioavailability or bioequivalence trials, were essential to the approval
of the application and were conducted or sponsored by the applicant.

There is a risk that the FDA may disagree with any claim that we may make that any of our prodrug product candidates are NCEs and therefore entitled to five-year exclusivity.
The  FDA  may  also  take  the  view  that  the  studies  that  we  are  conducting  are  not  clinical  trials,  other  than  bioavailability  and  bioequivalence  studies,  that  are  essential  to
approval and therefore do not support three-year exclusivity. Further, to the extent that the basis for exclusivity is not clear, the FDA may determine to defer a decision until it
receives an application which necessitates a decision.

If we do obtain either five or three years of exclusivity, such exclusivity will not block all potential competitors from the market. Competitors may be able to obtain approval for
similar  products  with  different  forms  of  competitive  differentiating  mechanisms  or  may  be  able  to  obtain  approval  for  similar  products  without  a  competitive
differentiating mechanism.

Even  if  we  or  our  collaborators  are  able  to  commercialize  AZSTARYS, APADAZ,  or  any  of  our  other  product  candidates,  they  may  be  subject  to  unfavorable  pricing
regulations, third-party coverage and reimbursement policies.

The  successful  commercialization  of  AZSTARYS,  APADAZ,  and  any  of  our  other  product  candidates  will  depend,  in  part,  on  the  extent  to  which  coverage  and  adequate
reimbursement for AZSTARYS, APADAZ, or any of our other product candidates, will be available from government payor programs at the federal and state levels, including
Medicare and Medicaid, private health insurers and managed care plans and other third-party payors. Government authorities and other third-party payors decide which medical
products they will pay for and establish reimbursement levels, including co-payments. A trend in the U.S. healthcare industry and elsewhere is cost containment. Government
authorities and other third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medical products. Increasingly,
third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for drugs and products.
Coverage and reimbursement may not be available for any product that we commercialize and, even if these are available, the level of reimbursement may not be satisfactory.
Inadequate reimbursement levels may adversely affect the demand for, or the price of, AZSTARYS, APADAZ, or any of our other product candidates for which we obtain
marketing  approval.  Obtaining  and  maintaining  adequate  reimbursement  for  our  prodrug  products  may  be  difficult.  We  may  be  required  to  conduct  expensive
pharmacoeconomic studies to justify coverage and reimbursement or the level of reimbursement relative to other therapies. Moreover, the trend has been for government and
commercial health plans and their pharmacy benefit managers to commoditize drug products through therapeutic equivalence determinations, making formulary decisions based
on  cost.  If  coverage  and  adequate  reimbursement  are  not  available  or  reimbursement  is  available  only  at  limited  levels,  we  may  not  be  able  to  successfully  commercialize
AZSTARYS  under  the  KP415  License  Agreement,  APADAZ  under  the  APADAZ  License  Agreement,  or  commercialize  any  of  our  other  product  candidates  for  which
marketing approval is obtained.

There may be significant delays in obtaining coverage and reimbursement for newly approved prodrug products, and coverage may be more limited than the indications for
which the product is approved by the FDA or similar regulatory authorities outside the United States. Moreover, eligibility for coverage and reimbursement does not imply that
a product will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution expenses. Interim reimbursement
levels for new prodrug products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the
use of the product and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing
payments for other services. Net prices for prodrug products may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors
and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Private third-party
payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Except for certain government health care programs,
such as the Department of Defense’s TRICARE Uniform Formulary, no uniform policy requirement for coverage and reimbursement for drug products exists among third-party
payors  in  the  United  States.  Even  state  Medicaid  programs  have  their  own  preferred  drug  lists  that  may  disadvantage  non-preferred  brand  drugs.  Therefore,  coverage  and
reimbursement can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to
provide  scientific  and  clinical  support  for  the  use  of  our  products  to  each  payor  separately,  with  no  assurance  that  coverage  and  adequate  reimbursement  will  be  applied
consistently or obtained at all. Our inability to promptly obtain coverage and adequate reimbursement rates from both government-funded and private payors for any approved
prodrug  products  that  we  develop  could  significantly  harm  our  operating  results,  our  ability  to  raise  capital  needed  to  commercialize  prodrugs  and  our  overall  financial
condition.

The regulations that govern marketing approvals, pricing, coverage and reimbursement for new drugs vary widely from country to country. Current and future legislation may
significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining approvals. Some countries require approval of the sale
price of a product before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign
markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing
approval  for  a  product  in  a  particular  country,  but  then  be  subject  to  price  regulations  that  delay  commercial  launch  of  the  product,  possibly  for  lengthy  time  periods,  and
negatively impact the revenue able to be generated from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in
one or more product candidates, even if our product candidates obtain marketing approval.

There can be no assurance that AZSTARYS, APADAZ, or any of our other product candidates, if they are approved for sale in the United States or in other countries, will be
considered medically reasonable and necessary for a specific indication, that they will be considered cost-effective by third-party payors, that coverage or an adequate level of
reimbursement  will  be  available,  or  that  third-party  payors’  reimbursement  policies  will  not  adversely  affect  the  ability  to  sell  AZSTARYS  under  the  KP415  License
Agreement , APADAZ under the APADAZ License Agreement, or our ability to sell any of any of our other product candidates profitably if they are approved for sale.

60

 
 
 
 
 
 
 
We may be subject to enforcement action if we engage in improper marketing or promotion of our products.

The  FDA  closely  regulates  promotional  materials  and  other  promotional  activities.  Even  if  the  FDA  initially  approves  product  labeling  that  includes  a  description  of  our
improved  attribute  claims,  the  FDA  may  object  to  our  marketing  claims  and  product  advertising  campaigns.  Failure  to  comply  with  the  FDA’s  promotional,  marketing  and
advertising laws and regulations could lead to the issuance of warning letters, cyber letters, or untitled letters, adverse publicity, the requirement for dear-health-care-provider
letters or other corrective information, fines and other monetary penalties, civil or criminal prosecution, including False Claims Act liability, restrictions on our operations and
other operating requirements through consent decrees or corporate integrity agreements, debarment, exclusion from participation in federal health care programs and refusal of
government contracts or future orders under existing contracts, among other consequences. Any of these consequences would harm the commercial success of our products.

Further, our promotional materials, statements and training methods must comply with the FDA’s prohibition of the promotion of unapproved, or off-label, use. Physicians may
use  our  products  off-label,  as  the  FDA  does  not  restrict  or  regulate  a  physician’s  independent  choice  of  treatment  within  the  practice  of  medicine.  However,  if  the  FDA
determines  that  our  promotional  materials,  statements  or  training  constitutes  promotion  of  an  off-label  use,  it  could  request  that  we  modify  our  promotional  materials,
statements  or  training  methods  or  subject  us  to  regulatory  or  enforcement  actions,  such  as  the  issuance  of  an  untitled  letter,  a  warning  letter,  injunction,  seizure,  civil  fine,
disgorgement of money, operating restrictions or criminal penalties. We may also be subject to actions by other governmental entities or private parties, such as the False Claims
Act, civil whistleblower or “qui tam” actions. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our promotional or
training materials to constitute promotion of an off-label use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false
claims for reimbursement. In that event, our reputation could be damaged and adoption of the products could be impaired. In addition, the off-label use of our products may
increase the risk of product liability claims. Product liability claims are expensive to defend and could divert our management’s attention, result in substantial damage awards
against us and harm our reputation.

61

 
 
 
 
 
Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of AZSTARYS, APADAZ, or any of our other product
candidates that we may develop.

We  face  an  inherent  risk  of  product  liability  exposure  related  to  the  testing  of  our  product  candidates  in  human  clinical  trials  and  will  face  an  even  greater  risk  as
AZSTARYS, APADAZ,  and  any  of  our  other  product  candidates  that  may  be  approved  in  the  future,  are  commercialized.  This  includes  the  risk  that  our  products  may  be
misused.  For  example,  AZSTARYS  does, APADAZ  does,  and  we  anticipate  that  any  of  our  other  product  candidates  we  may  choose  to  develop  in  the  future,  if  approved,
may carry, a boxed warning regarding lethality if our oral tablets or capsules are prepared for injection and hepatotoxicity, as is commonly done by abusers of opioids. If we
cannot  successfully  defend  ourselves  against  claims  that  our  product  candidates  or  products  caused  injuries,  we  will  incur  substantial  liabilities  on  behalf  of  ourselves.
Regardless of merit or eventual outcome, liability claims may result in:

  ● decreased demand for AZSTARYS, APADAZ, and any of our other product candidates that we may develop;

  ● injury to our reputation and significant negative media attention;

  ● termination of clinical trial sites or entire trial programs;

  ● withdrawal of clinical trial participants;

  ● initiation of investigations by regulators;

  ● significant costs to defend the related litigation;

  ● a diversion of management’s time and our resources;

  ● substantial monetary awards paid to trial participants or patients;

  ● product recalls, withdrawals or labeling revisions and marketing or promotional restrictions;

  ● loss of revenue;

  ● reduced resources of our management to pursue our business strategy; and

  ● the inability to successfully commercialize AZSTARYS, APADAZ, or any of our other product candidates that might be approved in the future.

We currently hold $10.0 million in product liability insurance coverage in the aggregate, with a per incident limit of $10.0 million, which may not be adequate to cover all
liabilities that we may incur. We may need to increase our insurance coverage as we expand our clinical trials or upon commencement of commercialization of any product
approved in the future. Insurance coverage is increasingly expensive. 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.

A variety of risks associated with international operations could materially adversely affect our business.

We expect to engage in significant cross-border activities, and we will be subject to risks related to international operations, including:

  ● different regulatory requirements for maintaining approval of drugs in foreign countries;

  ● differing payor reimbursement regimes, governmental payors or patient self-pay systems and price controls;

  ● reduced protection for contractual and intellectual property rights in some countries;

  ● unexpected changes in tariffs, trade barriers and regulatory requirements;

  ● economic weakness, including inflation, or political instability in particular foreign economies and markets;

  ● compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

● foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another

country;

  ● workforce uncertainty in countries where labor unrest is more common than in North America;

  ● tighter restrictions on privacy and the collection and use of patient and clinical trial participant data; and

  ● business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters including earthquakes, typhoons, floods and fires.

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

Failure to obtain marketing approval in international jurisdictions would prevent AZSTARYS, APADAZ, and any of our other product candidates from being marketed
abroad.

In  order  to  market  and  sell  our  products  in  the  European  Union  and  any  other  jurisdictions,  we  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 product be approved for reimbursement before the product can be approved for
sale  in  that  country.  We  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 ability to obtain approval elsewhere. We
may not be able to file for marketing approvals and may not receive necessary approvals to commercialize our products in any market.

A variety of risks associated with marketing AZSTARYS, APADAZ, and any of our other product candidates internationally, if approved, could affect our business.

We may seek regulatory approval for AZSTARYS, APADAZ, and any of our other product candidates, if approved, outside of the United States and, accordingly, we expect that
we will be subject to additional risks related to operating in foreign countries if we obtain the necessary approvals, 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;

  ● 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 Foreign Corrupt Practices Act of 1977 or comparable foreign regulations;

● challenges enforcing our 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; and

  ● business interruptions resulting from geo-political actions, including war and terrorism.

These and other risks associated with our international operations may compromise our ability to achieve or maintain profitability.

AZSTARYS is, APADAZ is, and any of our other product candidates for which we obtain marketing approval could be, subject to post-marketing restrictions or recall or
withdrawal  from  the  market,  and  we  may  be  subject  to  penalties  if  we  or  our  collaborators  fail  to  comply  with  regulatory  requirements  or  if  we  or  our  collaborators
experience unanticipated problems with AZSTARYS, APADAZ, or any of our other product candidates when and if any of them are approved.

AZSTARYS is, APADAZ is, and any of our other product candidates for which we obtain marketing approval could be, subject to a comprehensive regulatory scheme, which
includes the regulation of manufacturing processes, post-approval clinical data, labeling, advertising, marketing, distribution and promotional activities for such product, by the
FDA and other regulatory authorities. For example, we are required to conduct pediatric studies related to AZSTARYS to determine its safety and effectiveness for the claimed
indication in pediatric patients. Under the KP415 License Agreement, Commave will be responsible for these regulatory activities going forward, and we cannot guarantee they
will  be  complied  with.  In  addition,  we  are  required  to  conduct  pediatric  studies  related  to  APADAZ  to  determine  its  safety  and  effectiveness  for  the  claimed  indication  in
pediatric  patients.  Under  the  APADAZ  License  Agreement,  KVK  will  be  responsible  for  these  regulatory  activities  going  forward,  and  we  cannot  guarantee  they  will  be
complied  with.    These  requirements  include  submissions  of  safety  and  other  post-marketing  information  and  reports,  registration  and  listing  requirements,  payment  of
substantial annual product and establishment fees, labeling requirements, promotional, marketing and advertising requirements, requirements related to further development,
packaging, storage and distribution 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. If there are any modifications to the drug, including changes in indications,
labeling, manufacturing processes or facilities, or new safety issues arise, a new or supplemental NDA, a post-implementation notification or other reporting may be required or
requested depending on the change, which may require additional data or additional preclinical studies and clinical trials.

AZSTARYS is, APADAZ is, and if marketing approval of any of our other product candidates is granted may be, subject to limitations on the indicated uses for which the
product  may  be  marketed  or  to  the  conditions  of  approval,  including  the  requirement  to  implement  a  REMS,  which  could  involve  requirements  for,  among  other  things,  a
medication guide, special training for prescribers and dispensers, and patient registries. For example, in September 2018, the FDA approved the Opioid Analgesic REMS for
ER/LA and IR opioids as one strategy among multiple national and state efforts to reduce the risk of abuse, misuse, addiction, overdose, and deaths due to prescription opioid
analgesics. APADAZ is subject to this REMS, and we anticipate that any of our other opioid product candidates that we may choose to develop in the future, if approved by the
FDA, are likely to also be subject to a REMS requirement.

AZSTARYS does, APADAZ does, and if any of our other product candidates receive marketing approval they may, have a label that limits their approved uses, including more
limited subject populations, than we request, and regulatory authorities may require that contraindications, warnings or precautions be included in the product labeling,
including a boxed warning, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful
commercialization of that product candidate, which could limit sales of the product. For instance, we expect that at least some of our product candidates would likely be
required to carry boxed warnings, including warnings regarding tampering, lethality if our oral tablets or capsules are prepared for injection and hepatotoxicity.

The FDA may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of the product. APADAZ is subject
to a post-marketing requirement for four deferred pediatric assessments that must be completed pursuant to the FDA’s February 2018 approval letter. The FDA closely regulates
the post-approval marketing and promotion of products to ensure products 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 we do not market our prodrug products, if any, for their
approved indications, we may be subject to enforcement action for off-label marketing. Violations of the Federal Food, Drug and Cosmetic Act relating to the promotion of
prescription drugs may lead to a number of actions and penalties, including warning letters, cyber letters, or untitled letters, adverse publicity, the requirement for dear-health-
care-provider letters or other corrective information, fines and other monetary penalties, civil or criminal prosecution, including False Claims Act liability, restrictions on our
operations and other operating requirements through consent decrees or corporate integrity agreements, debarment, exclusion from participation in federal health care programs
and refusal of government contracts or future orders under existing contracts, among other consequences.

65

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

  ● adverse inspectional findings;

  ● restrictions on such prodrug products, distribution, manufacturers or manufacturing processes;

  ● restrictions on the labeling or marketing of a drug;

  ● additional warnings or otherwise restrict the product’s indicated use, label, or marketing;

  ● issuance of safety alerts, dear-healthcare-provider letters, press releases or other communications containing warnings regarding the product;

  ● requirement to establish or modify a REMS;

  ● requirement to conduct post-marketing studies or surveillance;

  ● restrictions on drug distribution or use;

  ● requirements to conduct post-marketing studies or clinical trials;

  ● warning letters;

  ● recall or withdrawal of the prodrug products from the market;

  ● refusal to approve pending applications or supplements to approved applications that we submit and other delays;

  ● clinical holds, or the suspension or termination of ongoing clinical trials;

  ● fines, restitution or disgorgement of profits or revenue;

  ● suspension or withdrawal of marketing approvals or other permits or voluntary suspension of marketing;

  ● refusal to permit the import or export of our prodrug products;

  ● reputational harm;

  ● refusal  of  government  contracts  or  future  orders  under  existing  contracts,  exclusion  from  participation  in  federal  health  care  programs,  and  corporate  integrity

agreements;

  ● product seizure or detention; or 

  ● injunctions or the imposition of civil or criminal penalties, including False Claims Act liability.

Non-compliance  with  European  Union  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.

Our  employees,  independent  contractors,  principal  investigators,  CROs,  consultants,  commercial  collaborators,  contract  manufacturers,  service  providers  and  other
vendors may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements.

We are exposed to the risk of misconduct by employees and independent contractors, such as principal investigators, CROs, consultants, commercial collaborators, contract
manufacturers, service providers and other vendors. Such misconduct could include failures to comply with FDA regulations, to provide accurate information to the FDA, to
comply with manufacturing standards that we have established or that are established by regulation, to comply with federal and state contracting and healthcare fraud and abuse
laws, to report drug pricing, financial information or data accurately or to disclose unauthorized activities to us. In particular, sales, marketing and other business arrangements
in the healthcare industry are subject to extensive laws intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws may restrict or prohibit a wide
range of business activities, including, but not limited to, research, manufacturing, distribution, pricing, discounting, marketing, advertising and promotion, sales commissions,
customer  incentive  programs  and  other  business  arrangements.  Employee  and  independent  contractor  misconduct  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.  In  addition,  federal  procurement  laws  impose  substantial  penalties  for  misconduct  in  connection  with  government  contracts  and  require  certain  contractors  to
maintain a code of business ethics and conduct and self-disclose credible evidence of False Claims Act violations. It is not always possible to identify and deter employee and
independent contractor misconduct, and any precautions we take to detect and prevent improper activities 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. If any such actions are
instituted against us, those actions could have a significant impact on our business, including the imposition of warning letters, untitled letters, cyber letters, seizure or recall of
products, injunctions, withdrawal of product approval or other permits, clinical holds and termination of clinical trials, FDA refusal to approve pending applications, product
detentions, FDA or DEA consent decrees, restriction or suspension of manufacturing and distribution, debarment, refusal to allow product import or export, adverse publicity,
refusal  of  government  contracts  or  future  orders  under  existing  contracts,  dear-health-care-provider  letters  or  other  warnings  or  corrective  information,  recalls,  delays,
significant  civil,  criminal  and  administrative  penalties  including  False  Claims  Act  liability,  damages,  monetary  fines,  disgorgement,  restitution,  possible  exclusion  from
participation  in  Medicare,  Medicaid  and  other  federal  healthcare  programs,  corporate  integrity  agreements,  contractual  damages,  reputational  harm,  diminished  profits  and
future earnings and curtailment or restructuring of our operations, among other consequences, any of which could adversely affect our ability to operate.

67

 
 
 
 
Our  current  and  future  relationships  with  healthcare  professionals,  principal  investigators,  consultants,  customers  and  third-party  payors  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 healthcare laws and regulations, which could expose us to penalties.

Healthcare providers, physicians and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription of our products, as
well as any product candidates for which we obtain marketing approval. Our current and future arrangements with healthcare professionals, principal investigators, consultants,
customers and third-party payors may expose us to broadly applicable fraud and abuse and other healthcare laws, including, without limitation, the Anti-Kickback Statute and
the False Claims Act, that may constrain the business or financial arrangements and relationships through which we sell, market and distribute any product candidates for which
we obtain marketing approval. In addition, we may be subject to physician payment transparency laws and patient privacy and security regulation by the federal government
and by the U.S. states and foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws that may affect our 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  paying
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,  lease,  order  or
arranging for the purchase, lease or order of, any good, facility, item or service, for which payment may be made, in whole or in part, under federal and state healthcare
programs such as Medicare and Medicaid;

  ● federal civil and criminal false claims laws, including the False Claims Act, which impose criminal and civil penalties, including through civil whistleblower or qui tam
actions, against individuals or entities for, among other things, 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 or using a false record or statement material to a false or fraudulent claim or to avoid,
decrease  or  conceal  an  obligation  to  pay  money  to  the  federal  government,  including  erroneous  pricing  information  on  which  mandatory  rebates,  discounts  and
reimbursement amounts are based, or in the case of the False Claims Act, for violations of the federal Anti-Kickback Statute in connection with a claim for payment or
for conduct constituting reckless disregard for the truth;

  ● the  civil  monetary  penalties  statute,  which  imposes  penalties  against  any  person  or  entity  who,  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;

  ● the Health Insurance Portability and Accountability Act, or HIPAA, which created additional federal criminal statutes that prohibit knowingly and willfully executing, or
attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations or promises, any of the
money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of whether the payor is public or private, 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 by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment  for,
healthcare benefits, items or services relating to healthcare matters;

  ● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 and their respective implementing regulations, which impose
obligations on covered entities, including certain healthcare providers, health plans, and healthcare clearinghouses, as well as their respective business associates that
create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity and their covered subcontractors, 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, or the ACA, and its implementing regulations, which imposes new annual
reporting requirements for manufacturers of drugs, devices, biologicals and medical supplies for which payment is available under Medicare, Medicaid or the Children’s
Health  Insurance  Program,  with  certain  exceptions,  to  annually  report  certain  payments  and  transfers  of  value  provided  to  physicians  (defined  to  include  doctors,
dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and
teaching hospitals, and to report annually certain ownership and investment interests held by physicians and their immediate family members, and, beginning in 2022,
will require applicable manufacturers 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; and

  ● comparable state and foreign laws, which may be broader in scope than the analogous federal laws and may differ from each other in significant ways.

These laws may affect our sales, marketing, and other promotional activities by imposing administrative and compliance burdens on us. 

Efforts to ensure that our current and future business arrangements with third parties will comply with applicable healthcare laws and regulations may involve substantial costs.
It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable
fraud  and  abuse  or  other  healthcare  laws,  or  that  our  compliance  systems  are  inadequate  to  detect  and  report  such  conduct  or  to  report  accurate  pricing  information  to  the
government. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant
civil, criminal and administrative penalties, including, without limitation, damages, fines, imprisonment, exclusion from participation in government healthcare programs, such
as Medicare and Medicaid, corporate integrity agreements or similar agreements to resolve allegations of non-compliance with these laws, and the curtailment or restructuring
of  our  operations,  which  could  significantly  harm  our  business.  If  any  of  the  physicians  or  other  healthcare  providers  or  entities  with  whom  we  currently,  or  expect  to,  do
business, including future collaborators, is found not to be in compliance with applicable laws, they and we may be subject to significant penalties and potential exclusion from
participation in healthcare programs as a result of their non-compliance.

Recently  enacted  and  future  legislation  may  increase  the  difficulty  and  cost  for  us  to  obtain  marketing  approval  of  our  product  candidates  and  increase  the  cost
to commercialize AZSTARYS, APADAZ, and any of our product candidates that may be approved in the future and affect the prices thereof.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that
could, among other things, prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect the ability to profitably sell
AZSTARYS under the KP415 License Agreement or APADAZ under the APADAZ License Agreement and our ability to profitably sell any of our other product candidates for
which we obtain marketing approval.

Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing
healthcare  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. In March 2010, President Obama signed into law the ACA, a sweeping law intended to broaden access to health insurance,
reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance
industries, impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the ACA of importance to our potential product candidates 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 healthcare 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 drugs and generic drugs, respectively;

● expansion  of  healthcare  fraud  and  abuse  laws,  including  the  False  Claims  Act  and  the  federal  Anti-Kickback  Statute,  new  government  investigative  powers  and

enhanced penalties for non-compliance;

● establishment of a new and distinct 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;

● a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices (generally as
negotiated between the Medicare Part D plan and the pharmacy) 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  and
extension of the inflation percentage applicable to existing branded drugs to new formulations for purposes of computing the inflation penalty component of Medicaid
rebates;

● expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new
mandatory  eligibility  categories  for  certain  individuals  with  income  at  or  below  133%  of  the  Federal  Poverty  Level,  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 

● 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 have been executive, judicial and congressional challenges to certain aspects of the ACA. While Congress has not passed comprehensive repeal legislation, several bills
affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017 includes a provision repealing the tax-based shared
responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the
“individual  mandate”.  Additionally,  the  2020  federal  spending  package  permanently  eliminated,  effective  January  1,  2020,  the  ACA-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 ACA 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 ACA 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  5th  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 ACA 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
ACA, 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 ACA 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 ACA. It is unclear how the Supreme Court ruling, other
such litigation, and the healthcare reform measures of the Biden administration will impact the ACA and our business.

In  addition,  other  legislative  changes  have  been  proposed  and  adopted  since  the  ACA  was  enacted.  In  August  2011,  the  Budget  Control  Act  of  2011,  among  other  things,
created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2
trillion  for  the  years  2013  through  2021,  was  unable  to  reach  required  goals,  thereby  triggering  the  legislation’s  automatic  reduction  to  several  government  programs.  This
includes  aggregate  reductions  to  Medicare  payments  to  providers  of  up  to  2%  per  fiscal  year,  which  went  into  effect  in  April  2013,  and,  due  to  subsequent  legislative
amendments, 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.  In  January  2013,  President  Obama  signed  into  law  the  American  Taxpayer  Relief  Act  of  2012,  which,  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.

Further, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several
recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the
relationship between pricing and manufacturer patient programs, reduce the cost of drugs under Medicare, 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, the Trump administration 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, HHS finalized a regulation removing safe harbor
protection for price reductions from pharmaceutical manufacturers to plan sponsors under Medicare 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  the  Trump  administration’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  are  increasingly  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. These new
laws  may  result  in  additional  reductions  in  Medicare  and  other  healthcare  funding,  which  could  negatively  impact  customers  for  our  product  candidates,  if  approved,  and,
accordingly, our financial operations. It is also possible that additional governmental action is taken in response to the COVID-19 pandemic.

We expect that the healthcare reform measures that have been adopted and may be adopted in the future, may, among other things, result in more rigorous coverage criteria and
in additional downward pressure on the price that we receive for any approved product. 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 healthcare reforms may prevent us from being able to
generate revenue, attain profitability, or commercialize our prodrug product candidates.

Legislative  and  regulatory  proposals  and  enacted  statutes  have  been  made  to  expand  post-approval  requirements  and  restrict  sales  and  promotional  activities  for  drugs.  For
instance, the Drug Supply Chain Security Act imposes obligations on manufacturers of pharmaceutical products, among others, related to product tracking and tracing. Among
the requirements of this new legislation, manufacturers are required to provide specified information regarding the drug products they produce to individuals and entities to
which product ownership is transferred, label drug products with a product identifier and keep specified records regarding the drug products. The transfer of information to
subsequent product owners by manufacturers will eventually be required to be done electronically. Manufacturers are also required to verify that purchasers of products are
appropriately  licensed.  Further,  under  this  legislation,  manufacturers  have  drug  product  investigation,  quarantine,  disposition  and  FDA  and  trading-partner  notification
responsibilities  related  to  counterfeit,  diverted,  stolen  and  intentionally  adulterated  products,  as  well  as  products  that  are  the  subject  of  fraudulent  transactions  or  which  are
otherwise unfit for distribution such that they would be reasonably likely to result in serious health consequences or death.

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 the marketing approvals of our product 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 us to more stringent product labeling and post-marketing testing and other requirements.

70

 
 
 
 
 
 
 
 
Governments outside the United States tend to impose strict price controls, which may affect our revenue, if any.

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 product. To obtain coverage and reimbursement or pricing
approval  in  some  countries,  we  may  be  required  to  conduct  a  clinical  trial  that  compares  the  cost-effectiveness  of  our  product  candidate  to  other  available  therapies.  If
reimbursement  of  our  prodrug  products  is  unavailable  or  limited  in  scope  or  amount,  or  if  pricing  is  set  at  unsatisfactory  levels,  our  business  could  be  harmed,  possibly
materially.

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 research, development or production efforts. Our failure to comply with these laws and regulations also may result in substantial fines, penalties or
other sanctions.

If our security measures are compromised now, or in the future, or the security, confidentiality, integrity or availability of, our information technology, software, services,
communications  or  data  is  compromised,  limited  or  fails,  this  could  result  in  a  material  adverse  impact,  including  without  limitation,  a  material  interruption  to  our
operations, harm to our reputation, significant fines, penalties and liability, breach or a triggering of data protection laws, privacy policies and data protection obligations,
loss of customers or sales, or material disruption of our clinical trials or other business activity.

In the ordinary course of our business, we may collect, process and store proprietary, confidential and sensitive information, including personal information (including key-
coded data and health information), intellectual property, trade secrets and proprietary business information owned or controlled by ourselves or other parties.

Despite the implementation of security measures, our information technology systems and data, and those of our CROs and other third parties on which we rely, are vulnerable
to  system  failure,  interruption,  compromise  or  damage  from  several  sources,  such  as  data  corruption;  breakdown;  malicious  human  acts;  malicious  code  (such  as  computer
viruses or worms); fraudulent activity; employee misconduct, theft or error; denial-of-service attacks; public health epidemics (such as the COVID-19 pandemic); cyber-attacks
by sophisticated nation-state and nation-state supported actors; natural disasters; terrorism; war; and telecommunication and electrical failures. Moreover, our recovery systems
(and  those  of  third  parties  upon  whom  we  rely)  are  similarly  vulnerable.  Any  of  these  events  could  lead  to  the  unauthorized  access,  disclosure  and  use  of  proprietary,
confidential, or otherwise non-public information (such as personal information). The techniques used by criminal actors to attack computer systems are sophisticated, change
frequently and may originate from less regulated and remote areas of the world. As a result, we may not be able to address these techniques proactively or implement adequate
preventative measures. We may be required to expend significant resources, fundamentally change our business activities and practices, or modify our operations, including our
clinical trial activities, or information technology in an effort to protect against security breaches and to mitigate, detect and remediate actual and potential vulnerabilities. Due
to  the  nature  of  some  of  these  threats,  we  may  be  unable  to  anticipate  threats,  and  there  is  a  risk  that  a  threat  may  remain  undetected  for  a  period  of  time.  The  costs  of
maintaining or upgrading our cyber-security systems at the level commercially reasonable to keep up with our expanding operations and prevent against potential attacks are
increasing, and despite our best efforts, our network security and data recovery measures and those of our vendors may still not be adequate to protect against such security
breaches and disruptions, which could cause harm to our business, financial condition and results of operations.

If we, our service providers, partners, or other relevant third parties have experienced, or in the future experience, any security incident(s) that result in any data loss, deletion or
destruction, unauthorized access to, loss of, acquisition or disclosure of, exposure or disclosure of sensitive information, or compromise related to the security, confidentiality,
integrity  or  availability  of  our  (or  their)  information  technology,  software,  services,  communications  or  data,  it  may  result  in  a  material  adverse  impact,  including  without
limitation, fines, damages, litigation, enforcement actions, loss of trade secrets, a material disruption of our drug development programs, or other harm to our business. For
example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our
costs to recover or reproduce the data. 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 liability and the further development of our product candidates could be delayed. Additionally, applicable
data  protection  laws,  privacy  policies  and  data  protection  obligations  (such  as  contractual  obligations)  may  require  us  to  notify  relevant  stakeholders  of  security  breaches,
including affected individuals, customers and regulators. Such disclosures are costly, and the disclosure or the failure to comply with such requirements, could lead to material
adverse impacts, including without limitation, negative publicity, a loss of confidence in our products or operations or breach of contract claims. There can be no assurance that
the limitations of liability in our contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages if we fail to comply with applicable data
protection laws, privacy policies or data protection obligations related to information security or security breaches.

Further, failures or significant downtime of our information technology or telecommunication systems or those used by our third-party service providers could cause significant
interruptions  in  our  operations  and  adversely  impact  the  confidentiality,  integrity  and  availability  of  sensitive  or  confidential  information,  including  preventing  us  from
conducting clinical trials, tests or research and development activities and preventing us from managing the administrative aspects of our business.

We cannot be sure that our insurance coverage will be adequate or otherwise protect us from or adequately mitigate liabilities or damages with respect to claims, costs,
expenses, litigation, fines, penalties, business loss, data loss, regulatory actions or materially adverse impacts arising out of our privacy and cybersecurity practices, processing
or security breaches that we may experience, or that such coverage will continue to be available on acceptable terms at all. The successful assertion of one or more large claims
against us that exceeds our available insurance coverage, or results in changes to our insurance policies (including premium increases or the imposition of a large deductible or
co-insurance requirements), could have an adverse effect on our business. In addition, we cannot be sure that our existing coverage and coverage for errors and omissions will
continue to be available on acceptable terms or that our insurers will not deny coverage as to any future claim.

Failure or perceived failure to comply with existing or future laws, regulations, contracts, self-regulatory schemes, policies, standards and other obligations related to data
privacy  or  security  could  lead  to  government  enforcement  actions  (which  could  include  civil  or  criminal  fines  or  penalties),  a  disruption  of  our  clinical  trials  or
commercialization of our products, private litigation, other liabilities, and/or adverse publicity. Compliance or the failure to comply with such obligations could increase
the costs of our products, could limit their use or adoption, and could otherwise negatively affect our operating results and business.

Regulation of data (including personal data)is evolving, as federal, state, and foreign governments continue to adopt new, or modify existing, laws and regulations addressing
data privacy and security, and the collection, processing, storage, transfer, and use of data. We and our collaborators may be subject to current, new, or modified federal, state,
and foreign data protection laws and regulations (e.g., laws and regulations that address data privacy and security, including, without limitation, personal data such as health
data). These new or proposed laws and regulations are subject to differing interpretations and may be inconsistent among jurisdictions, and guidance on implementation and
compliance practices are often updated or otherwise revised, which adds to the complexity of processing personal data. Moreover, we are subject to the terms of our privacy and
security policies, representations, certifications, standards, publications, contracts and other obligations to third parties related to data privacy, security and processing. These
and  other  requirements  could  require  us  or  our  collaborators  to  incur  additional  costs  to  achieve  compliance,  limit  our  competitiveness,  necessitate  the  acceptance  of  more
onerous obligations in our contracts, restrict our ability to use, store, transfer, and process data, impact our or our collaborators’ ability to process or use data in order to support
the provision of our products, affect our or our partners’ ability to offer our products or operate in certain locations, cause regulators to reject, limit, or disrupt our clinical trial
activities, result in increased expenses, reduce overall demand for our products and services and make it more difficult to meet expectations of or commitments to customers or
collaborators.

In  the  United  States,  numerous  federal  and  state  laws  and  regulations,  including  state  data  breach  notification  laws,  state  information  privacy  laws  (e.g.,  the  California
Consumer Privacy Act of 2018, or CCPA), state health information privacy laws, and federal and state consumer protection laws and regulations (e.g., Section 5 of the Federal
Trade  Commission  Act),  govern  the  collection,  use,  disclosure,  and  protection  of  health-related  and  other  personal  data.  These  laws  and  regulations  could  apply  to  our
operations, the operations of our collaborators or other relevant stakeholders upon whom we depend. In addition, we may obtain health information from third parties (including
research  institutions  from  which  we  may  obtain  clinical  trial  data)  that  are  subject  to  privacy  and  security  requirements  under  HIPAA.  Depending  on  the  facts  and
circumstances, we could be subject to civil and criminal penalties, including if we knowingly obtain, use, or disclose individually identifiable health information maintained by
a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.

The  CCPA  became  effective  on  January  1,  2020.  The  CCPA  gives  California  residents  expanded  rights  to  access  and  delete  their  personal  information,  opt  out  of  certain
personal information sharing and receive detailed information about how their personal information is used. The CCPA requires covered entities to provide new disclosures to
California residents. The CCPA provides for civil penalties for violations, as well as a private right of action and statutory damages for data breaches that is expected to increase
class action data breach litigation. Although there are limited exemptions for clinical trial data, the CCPA’s implementation standards and enforcement practices are likely to
remain uncertain for the foreseeable future. The CCPA may increase our compliance costs and potential liability. It is anticipated that the CCPA will be expanded on January 1,
2023, when the California Privacy Rights Act of 2020 (“CPRA”) becomes operative. The CPRA will, among other things, give California residents the ability to limit use of
certain sensitive information, establish restrictions on the retention of personal information, expand the types of data breaches subject to the CCPA’s private right of action and
establish a new California Privacy Protection Agency to implement and enforce the new law. These laws demonstrate our vulnerability to the evolving regulatory environment
related to personal data. As we expand our operations, these and similar laws may increase our compliance costs and potential liability.

Foreign  data  protection  laws,  such  as,  without  limitation,  the  EU’s  GDPR  and  member  state  data  protection  laws,  may  also  apply  to  health-related  and  other  personal
information that we process, including, without limitation, personal data relating to clinical trial participants. European data protection laws impose strict obligations on the
ability  to  process  health-related  and  other  personal  information  of  data  subjects  in  Europe,  including,  among  other  things,  standards  relating  to  the  privacy  and  security  of
personal data, which require the adoption of administrative, physical and technical safeguards designed to protect such information. The United Kingdom’s vote in favor of
exiting the EU, often referred to as Brexit, has created uncertainty with regard to data protection regulation in the United Kingdom. Beginning in 2021, the UK will be a “third
country” under the GDPR and transfers of European personal information to the U.K. will require an adequacy mechanism to render such transfers compliant under the GDPR.
European data protection laws may affect our use, collection, analysis, and transfer (including cross-border transfer) of such personal information. These laws include several
requirements relating to transparency related to communications with data subjects regarding the processing of their personal data, obtaining the consent of the individuals to
whom  the  personal  data  relates,  limitations  on  data  processing,  establishing  a  legal  basis  for  processing,  notification  of  data  processing  obligations  or  security  incidents  to
appropriate data protection authorities or data subjects, the security and confidentiality of the personal data and various rights that data subjects may exercise.

European data protection laws prohibit the transfer, without an appropriate legal basis, of personal data to countries outside of Europe, such as to the United States, which are
not considered by the relevant authorities to provide an adequate level of data protection. A decision by the Court of Justice of the European Union (the “Schrems II” ruling)
invalidated  the  EU-U.S.  Privacy  Shield  Framework,  and  raised  questions  about  whether  the  European  Commission’s  Standard  Contractual  Clauses  (“SCCs”),  one  of  the
primary alternatives to the Privacy Shield, can lawfully be used for personal information transfers from Europe to the United States or most other countries. Similarly, the Swiss
Federal Data Protection and Information Commissioner recently opined that the Swiss-U.S. Privacy Shield is inadequate for transfers of personal data from Switzerland to the
U.S.  The  United  Kingdom,  whose  data  protection  laws  are  similar  to  those  of  the  European  Union,  may  similarly  determine  that  the  EU-U.S.  Privacy  Shield  is  not  a  valid
mechanism  for  lawfully  transferring  personal  data  from  the  United  Kingdom  to  the  United  States.  The  European  Commission  recently  proposed  updates  to  the  SCCs,  and
additional  regulatory  guidance  has  been  released  that  seeks  to  impose  additional  obligations  on  entities  that  rely  on  the  SCCs.  Given  that,  at  present,  there  are  few,  if  any,
alternatives to the EU-U.S. Privacy Shield and the SCCs, any transfers by us or our vendors of personal data from Europe may not comply with European data protection laws,
which may increase our exposure to such laws’ sanctions for violations of its cross-border transfer restrictions and may prohibit our transfer of European personal data outside
of Europe, and may adversely impact our operations, product development and ability to provide our products.  Additionally, other countries have passed or are considering
passing laws requiring local data residency and/or restricting the international transfer of data.

For example, under the GDPR, regulators may impose substantial fines and penalties for non-compliance. Entities that violate the GDPR can face fines of up to the greater of
20 million Euros or 4% of their worldwide annual turnover (revenue). Additionally, regulators could prohibit our use of personal data subject to the GDPR. The GDPR has
increased our responsibility and liability in relation to personal data that we process, requiring us to put in place additional mechanisms to comply with the GDPR and other
foreign data protection requirements.

Failure, or perceived failure, to comply with federal, state and foreign data protection laws and regulations, privacy policies, contracts and other data protection obligations
could  result  in  government  investigations  and  enforcement  actions  (which  could  include  civil  or  criminal  penalties,  fines,  or  sanctions),  private  litigation,  a  diversion  of
management’s attention, adverse publicity and other negative effects on our operating results and business. There can be no assurance that the limitations of liability in our
contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages if we fail to comply with applicable data protection laws, privacy policies
or data protection obligations related to information security or security breaches. Moreover, clinical trial participants or subjects about whom we or our collaborators obtain
information, as well as the providers who share this information with us, may contractually limit our ability to use and disclose the information. Claims that we have violated
individuals’ privacy rights or failed to comply with data protection laws, contracts, privacy notices or other obligations even if we are not found liable, could be expensive and
time-consuming to defend and could result in adverse publicity that could harm our business.

Any of these matters could materially adversely affect our business, financial condition, or operational results.

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, research and development, clinical, financial and business development expertise of Travis C. Mickle, Ph.D., our president and
chief executive officer, R. LaDuane Clifton, CPA, our chief financial officer, and Sven Guenther, Ph.D., our executive vice president research and development, as well as the
other members of our scientific and clinical teams. Although we have employment agreements with each of our executive officers, these agreements do not obligate them to
continue working for our company and they may terminate their employment with us at any time.

Recruiting  and  retaining  qualified  scientific  and  clinical  personnel  and,  if  we  progress  the  development  of  our  product  candidate  pipeline  toward  scaling  up  for
commercialization,  manufacturing  and  sales  and  marketing  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 research, development and commercialization 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,  gain  regulatory  approval  of  and  commercialize  our  prodrug  product  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 research and
development and commercialization strategy. Our consultants and advisors may have commitments under 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.

Risks Related to Ownership of Our Common Stock and Our Status as a Public Company

The trading price of the shares of our common stock is likely to be volatile, and purchasers of our common stock could incur substantial losses.

Our stock price has been, and is likely to continue to be, volatile. Since shares of our common stock were sold in our initial public offering in April 2015 at a price of $176.00
per share (adjusted to give effect to the 1-for-16 reverse stock split), our stock price has ranged from a low of $1.94 to a high of $418.40 through March 10, 2021. In addition,
the  stock  market  in  general  and  the  market  for  pharmaceutical  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:

  ● actual or anticipated variations in our operating results;

  ● changes in financial estimates by us or by any securities analysts who might cover our stock;

  ● conditions or trends in our industry, including without limitation changes in the structure of healthcare payment systems;

  ● stock market price and volume fluctuations of comparable companies and, in particular, those that operate in the pharmaceutical industry;

  ● 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;

  ● adverse regulatory announcements or determinations regarding our product candidates;

  ● capital commitments;

  ● investors’ general perception of us and our business;

  ● recruitment or departure of key personnel; and

  ● sales of our common stock, including sales by our directors and officers or specific stockholders.

Many  of  the  factors  described  above  are  not  within  our  control.  For  instance,  in  May  2016,  we  announced  that  the  Anesthetic  and  Analgesic  Drug  Products  Advisory
Committee and the Drug Safety and Risk Management Advisory Committee of the FDA voted 16 to 4 for the approval of APADAZ but voted 18 to 2 against inclusion of
abuse-deterrent labeling for APADAZ. The announcement was followed by a substantial decrease in the trading price of our common stock on Nasdaq. Additionally, when we
announced  in  June  2016  that  the  FDA  had  issued  a  CRL  for  the  APADAZ  NDA,  the  trading  price  of  our  common  stock  on  Nasdaq  was  subject  to  another  substantial
decrease. We cannot guarantee that future announcements will not have similar effects on the trading price of our common stock.

In addition, in the past, stockholders have initiated class action lawsuits against pharmaceutical and biotechnology companies following periods of volatility in the market prices
of  these  companies’  stock.  For  instance,  in  December  2016,  we  received  notice  of  a  class  action  suit  filed  against  us  in  the  Iowa  District  Court  in  Johnson  County  by  a
stockholder alleging that we, certain of our senior executives and directors who signed the registration statement in connection with our initial public offering, and each of the
investment banks that acted as underwriters for the offering negligently issued untrue statements of material facts and omitted to state material facts required to be stated in the
registration  statement  and  incorporated  offering  materials  that  we  filed  with  the  SEC  in  support  of  the  offering.  In  June  2018,  the  case  was  dismissed  without  prejudice  to
members of the putative class. Future litigation could cause us to incur substantial costs and divert management’s attention and resources from our business. Further, companies
listed on The Nasdaq Capital Market, and biotechnology and pharmaceutical companies in particular, have experienced extreme price and volume fluctuations that have often
been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common
stock, regardless of our actual operating performance.

A portion of our outstanding warrants are entitled to certain anti-dilution protections which, if triggered, may cause dilution to your investment.

The Deerfield Warrant (as defined below) includes  exercise price protection provision, pursuant to which the exercise price of the Deerfield Warrant will be adjusted downward
on a broad-based weighted-average basis if we issue or sell any shares of common stock, convertible securities, warrants or options at a sale or exercise price per share less than
the  greater  of  (i)  $93.60  per  share,  which  represents  the  Deerfield  Warrant’s  exercise  price,  or  (ii)  the  closing  sale  price  of  our  common  stock  on  the  last  trading  date
immediately prior to such issuance or, in the case of a firm commitment underwritten offering, on the date of execution of the underwriting agreement between us and the
underwriters for such offering. Additionally, if we effect an “at the market offering”, as defined in Rule 415 of the Securities Act of 1933, as amended, or the Securities Act, of
our common stock, the exercise price of the Deerfield Warrant will be adjusted downward pursuant to this anti-dilution adjustment only if such sales are made at a price less
than  $93.60  per  share,  provided  that  this  anti-dilution  adjustment  will  not  apply  to  certain  specified  sales.    For  example,  in  January  2021,  we  entered  into  the  Inducement
Letters with certain holders of the Existing Warrants, pursuant to which such holders exercised for cash their Existing Warrants to purchase 6,620,358 shares of our common
stock in exchange the Inducement Warrants on substantially the same terms as the Existing Warrants, except as set forth in the following sentence, to purchase up to 7,944,430
shares of our common stock, which was equal to 120% of the number of shares of our common stock issued upon exercise of the Existing Warrants. The purchase price of the
Inducement Warrants was $0.125 per share underlying each Inducement Warrant, and the Inducement Warrants have an exercise price of $6.36 per share.  The completion of
this transaction resulted in the exercise price of the Deerfield Warrant being adjusted downward to $46.25 per share.

Future sales and issuances of equity and debt could result in additional dilution to our stockholders.

We may need additional capital in the future to fund our planned future operations, including to complete potential clinical trials for our product candidates. To raise capital, we
may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time.

For instance in January 2021, we issued and sold 6,765,463 shares of our common stock, pre-funded warrants to purchase 926,844 shares of our common stock and warrants to
purchase  7,692,307  shares  of  our  common  stock  at  an  exercise  price  per  share  of  $6.50  in  the  Public  Offering.  Also  in  January  2021,  the  underwriter  exercised  its  over-
allotment option, in part, for warrants to purchase 754,035 shares of our common stock. Further, in February 2021, the underwriter again exercised its over-allotment option, in
part, to purchase 374,035 shares of our common stock.

Also in January 2021, we entered into the Inducement Letters with certain holders of the Existing Warrants, pursuant to which such holders exercised for cash their Existing
Warrants to purchase 6,620,358 shares of our common stock in exchange the Inducement Warrants on substantially the same terms as the Existing Warrants, except as set forth
in  the  following  sentence,  to  purchase  up  to  7,944,430  shares  of  our  common  stock,  which  was  equal  to  120%  of  the  number  of  shares  of  our  common  stock  issued  upon
exercise of the Existing Warrants. The purchase price of the Inducement Warrants was $0.125 per share underlying each Inducement Warrant, and the Inducement Warrants
have an exercise price of $6.36 per share.

Upon closing of the transactions contemplated under the December 2020 Exchange Agreement in January 2021, the holders of our Series B-2 convertible preferred stock are
able to convert all or any portion of their shares of Series B-2 convertible preferred stock at any time following the PDUFA Date (as defined in the certificate of designation) at
a conversion price equal to $6.4999 price per share.

According  to  the  terms  of  the  shares  of  Series  B-2  convertible  preferred  stock  in  no  event  may  any  holder  thereof  convert  such  holder’s  shares  of  Series  B-2  convertible
preferred stock to the extent such conversion would result in such holder beneficially owning more than 4.985% of the then issued and outstanding shares of our common stock.
This conversion limitation may not be waived and any purported conversion that is inconsistent with this conversion limitation will be null and void. This conversion limitation
will  not  apply  to  any  conversion  made  immediately  prior  to  a  change  of  control  transaction.  If  an  equityholder  is  only  able  to  convert  such  holder’s  shares  of  Series  B-2
convertible preferred stock into a limited number of shares due to this conversion limitation, such shares of Series B-2 convertible preferred stock could subsequently become
convertible into the remainder of the shares as a result of a variety of events. This could occur, for example, if we issue more shares or such holder sells some of its existing
shares.

If the holders of our shares of Series B-2 convertible preferred stock elect to convert such shares into common stock, your ownership interest will be diluted and the market
price of our common stock may be materially and adversely effected.

Pursuant to our equity incentive plan, we may grant equity awards and issue additional shares of our common stock to our employees, directors and consultants, and the number
of shares of our common stock reserved for future issuance under this plan will be subject to automatic annual increases in accordance with the terms of the plans. To the extent
that new options are granted and exercised, or we issue additional shares of common stock in the future, our stockholders may experience additional dilution, which could cause
our stock price to fall.

The accounting method for the Deerfield Warrant, our previously outstanding senior secured convertible promissory notes and the warrant we issued to KVK under the
APADAZ License Agreement could have a material effect on our reported financial results.

The Deerfield Warrant, our previously outstanding senior secured convertible promissory notes and the warrant we issued to KVK under the APADAZ License Agreement
contain embedded derivatives, which require mark-to-market accounting treatment and could result in a gain or loss on a quarterly basis with regards to the mark-to-market
value of that feature. Such accounting treatment could have a material impact on, and could potentially result in significant volatility in, our quarterly results of operations.

Sales of a substantial number of shares of our common stock in the public 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.

Pursuant  to  the  terms  of  the  December  2020  Exchange  Agreement,  we  have  filed  a  registration  statement  to  register  for  resale  the  shares  of  common  stock  issuable  upon
conversion of the shares of preferred stock or exercise of the warrants issued under the December 2020 Exchange Agreement. We also filed a registration statement covering
the resale of the shares of our common stock issued or issuable upon the exercise of the Inducement Warrants. If these additional shares are sold, or if it is perceived that they
will be sold, in the public market, the trading price of our common stock could decline.

78

 
 
 
 
 
 
 
Anti-takeover provisions in our certificate of incorporation and bylaws, as well as provisions of Delaware law and the terms of some or our contracts, might discourage,
delay or prevent a change in control of our company or changes in our board of directors or management and, therefore, depress the price of our common stock.

Our certificate of incorporation and bylaws and Delaware law contain provisions that may discourage, delay or prevent a merger, acquisition or other change in control that
stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares of our common stock or transactions that our
stockholders might otherwise deem to be in their best interests. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove members of
our board of directors or our management. Therefore, these provisions could adversely affect the price of our stock. Our corporate governance documents include provisions:

  ● establishing a classified board of directors with staggered three-year terms so that not all members of our board of directors are elected at one time;

  ● providing that directors may be removed by stockholders only for cause;

  ● preventing the ability of our stockholders to call and bring business before special meetings and to take action by written consent in lieu of a meeting;

  ● requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for election to our

board of directors;

  ● permitting the board of directors to issue up to 10,000,000 shares of preferred stock with any rights, preferences and privileges they may designate;

  ● limiting the liability of, and providing indemnification to, our directors and officers;

  ● providing that vacancies may be filled by remaining directors;

  ● preventing cumulative voting; and

  ● providing for a supermajority requirement to amend our bylaws.

As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the General Corporation Law of the State of Delaware, which prohibits
a Delaware corporation from engaging in a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the
stockholder became an “interested” stockholder.

In addition, the provisions of our termination agreement with Aquestive and the Deerfield Warrant may delay or prevent a change in control of our company. For example, if we
enter into a merger, an asset sale or any other change of control transaction, then Aquestive will be entitled to a royalty equal to 10% of the price being paid to us and our
stockholders in such transaction which is attributable to the value of AZSTARYS, KP484 or KP879. Further, under the Deerfield Warrant, Deerfield has the right to demand that
we redeem the Deerfield Warrant for a cash amount equal to the Black-Scholes value of a portion of the warrant upon the occurrence of specified events, including a merger, an
asset sale or any other change of control transaction. A takeover of us may trigger the requirement that we repurchase the Deerfield Warrant, which could make it more costly
for a potential acquirer to engage in a business combination transaction with us.

Finally, in the event of a sale of the company, upon the amendment and restatement of the certificate of designation for our Series B-2 convertible preferred stock, the holders of
our Series B-2 convertible preferred stock, if any, will receive an amount equal to the greater of (i) $1,000 per share, or (ii) the amount per share each such holder would have
been entitled to receive if every share of Series B-2 Preferred Stock had been converted into common stock immediately prior to such sale of the company, in each case, plus
any declared but unpaid dividends thereon. This would in turn reduce the distribution to the holders of our common stock in such change of control.

Any provision of our certificate of incorporation, bylaws or Delaware law or any term of our contracts that has the effect of discouraging, delaying or preventing a change in
control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock and could also affect the price that some investors are willing
to pay for our common stock.

Our  certificate  of  incorporation  provides  that  the  Court  of  Chancery  of  the  State  of  Delaware  is  the  exclusive  forum  for  substantially  all  disputes  between  us  and  our
stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the sole and exclusive forum for (i) any derivative action or proceeding brought
on our behalf, (ii) any action asserting a breach of fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a
claim  against  us  arising  pursuant  to  any  provisions  of  the  Delaware  General  Corporation  Law,  or  DGCL,  our  certificate  of  incorporation  or  our  bylaws,  or  (iv)  any  action
asserting a claim against us that is governed by the internal affairs doctrine.

In addition, on and effective July 15, 2020, we amended and restated our bylaws, or the Bylaws, pursuant to which: (i) unless we consent in writing to the selection of an
alternative forum, the Court of Chancery of the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any state
court located within the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware) shall be
the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (A) any derivative action or proceeding brought on
behalf of us; (B) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers or other employees, to us or
our stockholders; (C) any action or proceeding asserting a claim against us or any of our current or former directors, officers or other employees, arising out of or pursuant to
any provision of the DGCL our certificate of incorporation or our Bylaws (as each may be amended from time to time); (D) any action or proceeding to interpret, apply, enforce
or determine the validity of our certificate of incorporation or our Bylaws (including any right, obligation, or remedy thereunder); (E) any action or proceeding as to which the
DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; and (F) any action or proceeding asserting a claim against us or any of our directors, officers or
other employees, governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the
indispensable  parties  named  as  defendants,  provided  that  this  provision  shall  not  apply  to  suits  brought  to  enforce  a  duty  or  liability  created  by  the  Securities  Act  or  the
Securities Exchange Act of 1934, as amended, or the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction; (ii) unless we consent in writing
to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America shall be the exclusive forum for the
resolution of any complaint asserting a cause of action arising under the Securities Act; and (iii) any person or entity holding, owning or otherwise acquiring any interest in any
security of us shall be deemed to have notice of and consented to the provisions of the Bylaws.

These choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or
other employees, which may discourage such lawsuits against us and our directors, officers and other employees. If a court were to find the choice of forum provision contained
in our certificate of incorporation or our Bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other
jurisdictions.

We might not be able to utilize a significant portion of our net operating loss carryforwards, which could adversely affect our profitability.

As of December 31, 2020, we had federal net operating loss carryforwards of approximately $226.0 million, due to prior period losses, $138.1 million of which, if not utilized,
will begin to expire in 2027. These net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities, which could adversely affect
our profitability. On December 22, 2017, the U.S. government enacted H.R. 1, “An Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on
the budget for fiscal year 2018” (informally titled the Tax Cuts and Jobs Act). Under the Tax Cuts and Jobs Act, U.S. federal net operating losses incurred in 2018 and in future
years may be carried forward indefinitely, but the deductibility of such federal net operating losses is limited. It is uncertain if and to what extent various states will conform to
the  Tax  Cuts  and  Jobs  Act.  To  the  extent  that  we  continue  to  generate  taxable  losses  in  the  United  States,  unused  losses  will  carry  forward  to  offset  future  taxable  income
(subject  to  any  applicable  limitations),  if  any.  In  addition,  under  Section  382  and  Section  383  of  the  Code,  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  performed  a  Section  382  ownership  change  analysis  in  2017  and
determined that we experienced an ownership change in 2010, which resulted in a portion of our net operating loss carryforwards being subject to an annual limitation under
Section 382 through 2012. No other ownership changes or limitations on our historical net operating loss carryforwards were noted through the year ended December 31, 2017.
In  addition,  we  may  experience  ownership  changes  in  the  future  as  a  result  of  subsequent  shifts  in  our  stock  ownership,  including  as  a  result  of  the  conversion  of  our
outstanding convertible debt or as a result of future changes in our stock ownership. If we determine that an ownership change has occurred and our ability to use our historical
net operating loss carryforwards is materially limited, it would harm our future operating results by increasing our future tax obligations.

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 affect the tax treatment of our domestic earnings,
if  any.  Any  new  taxes  could  adversely  affect  our  business  operations,  and  our  business  and  financial  performance.  Further,  existing  tax  laws,  statutes,  rules,  regulations  or
ordinances  could  be  interpreted,  changed,  modified  or  applied  adversely  to  us.  For  example,  legislation  enacted  in  2017,  informally  titled  the  Tax  Cuts  and  Jobs  Act,
significantly revised the Internal Revenue Code of 1986, as amended. Future guidance from the Internal Revenue Service and other tax authorities with respect to the Tax Cuts
and Jobs Act may affect us, and certain aspects of the Tax Cuts and Jobs 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 Tax Cuts and Jobs 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 Tax Cuts and Jobs 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.

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 of 2002, or 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 things, that we maintain effective disclosure controls and procedures and internal controls
over financial reporting. For our fiscal year ended December 31, 2020, we performed system and process evaluation and testing of our internal controls over financial reporting
to allow management to report on the effectiveness of our internal controls over financial reporting in our Annual Report on Form 10-K, as required by Section 404 of the
Sarbanes-Oxley  Act.  We  will  be  required  to  perform  this  evaluation  and  testing  of  our  internal  controls  over  financial  reporting  to  allow  management  to  report  on  the
effectiveness of our internal controls over financial reporting on an annual basis. This requires that we incur substantial additional professional fees and internal costs and that
we expend significant management efforts on an annual basis. We have and will be required to test our internal controls within a specified period, and, as a result, we may
experience difficulty in meeting these reporting requirements.

We may discover weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements.
Our internal controls 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 not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act, or if we are unable to maintain proper and effective internal controls, we may not
be  able  to  produce  timely  and  accurate  financial  statements.  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.

General Risk Factors

An active trading market for our common stock may not be sustained and you may not be able to resell your shares of our common stock for a profit, if at all.

An active trading market for our shares may not be sustained. If an active market for our common stock is not sustained, it may be difficult for you to sell our shares at an
attractive price or 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 securities or industry analysts publish about us or our business, our market and our
competitors. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share
price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial
markets, which could cause our share price or trading volume to decline.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will be your sole source of gains and
you may never receive a return on your investment.

You  should  not  rely  on  an  investment  in  our  common  stock  to  provide  dividend  income.  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. In addition, the terms of any future debt agreements may, preclude us
from  paying  dividends.  As  a  result,  capital  appreciation,  if  any,  of  our  common  stock  will  be  your  sole  source  of  gain  for  the  foreseeable  future.  Investors  seeking  cash
dividends should not purchase our common stock.

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

As a public company listed in the United States, we incur significant additional legal, accounting and other costs. These additional 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,  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.

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.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

You  should  read  the  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  together  with  our  financial  statements  and  related  notes  thereto
included elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form
10-K,  including  information  with  respect  to  our  plans  and  strategy  for  our  business  and  related  financing,  includes  forward-looking  statements  that  involve  risks  and
uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, our actual results could differ
materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a specialty pharmaceutical company focused on the discovery and development of proprietary prodrugs to treat serious medical conditions through our proprietary LAT
technology. We utilize our proprietary LAT technology to generate improved prodrug versions of drugs approved by the FDA as well as to generate prodrug versions of existing
compounds  that  may  have  applications  for  new  disease  indications.  Our  product  candidate  pipeline  is  focused  on  the  high  need  areas  of  ADHD,  SUD  and  IH.  Our  co-
lead clinical development candidates, AZSTARYS (formerly referred to as KP415) and KP484, are both based on a prodrug of d-MPH but with differing ER effect profiles, and
are intended for the treatment of ADHD. Our clinical product candidate for the treatment of SUD is KP879, based on a prodrug of d-MPH. Our preclinical prodrug product
candidate  for  the  treatment  of  IH  is  KP1077.  We  have  entered  into  a  collaboration  and  license  agreement  with  Commave  for  the  development,  manufacture  and
commercialization  of  our  product  candidates  containing  SDX  and  d-MPH.  In  addition,  we  have  announced  our  commercial  partnership  with  KVK  of  APADAZ,  an  FDA
approved IR combination product of benzhydrocodone, our prodrug of hydrocodone, and APAP for the short-term (no more than 14 days) management of acute pain severe
enough to require an opioid analgesic and for which alternative treatments are inadequate.

We expect that our sources of revenues will be through payments arising from our license agreements with Commave and KVK, our consulting agreement with
Corium and through other consulting arrangements and any other future arrangements we might enter into related to one of our other product candidates. To date, we
have generated revenue from the KP415 License Agreement in the form of the non-refundable upfront payment of $10.0 million, of which we paid Aquestive $1.0 million as a
royalty payment, a regulatory milestone payment of $5.0 million following the FDA’s acceptance of the AZSTARYS NDA, of which we paid Aquestive $0.5 million as a
royalty payment, reimbursement of out-of-pocket third-party research and development costs and payments related to the performance of consulting services. In addition, we
have generated revenue under the Corium Consulting Agreement and other consulting arrangements for the performance of consulting services as well as reimbursement of out-
of-pocket third-party costs associated with those services.

On March 2, 2021, we announced that the FDA approved the NDA for AZSTARYS, a once-daily product for the treatment of ADHD in patients ranging from six years and
older. Corium will lead the commercialization of AZSTARYS per the KP415 License Agreement. Corium expects to make AZSTARYS commercially available in the U.S. as
early as the second half of 2021.

We have had recurring negative cash flows from operations and, as of December 31, 2020, had an accumulated deficit of $258.5 million. Our cash flows used in operations for
the years ended December 31, 2020 and 2019 were $1.9 million and $23.7 million, respectively.

We expect to continue to incur significant expenses and minimal positive net cash flows from operations or negative net cash flows from operations for the foreseeable future,
and those expenses and losses may fluctuate significantly from quarter-to-quarter and year-to-year. We anticipate that our expenses will fluctuate substantially as we:

  ● continue our ongoing preclinical studies, clinical trials and our product development activities for our pipeline of product candidates;

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

  ● continue research and preclinical development and initiate clinical trials of our other product candidates;

  ● seek to discover and develop additional product candidates either internally or in partnership with other pharmaceutical companies;

  ● adapt our regulatory compliance efforts to incorporate requirements applicable to marketed products;

  ● maintain, expand and protect our intellectual property portfolio; and

  ● incur additional legal, accounting and other expenses in operating as a public company.

Our commercial revenue, if any, will be derived from royalties earned from the sales of AZSTARYS, APADAZ, or any of our other product candidates for which we obtain
regulatory approval. In September 2019, we entered into the KP415 License Agreement, pursuant to which we granted an exclusive, worldwide license to Commave to develop,
manufacture  and  commercialize  our  product  candidates  containing  SDX  and  d-MPH,  including AZSTARYS  and  KP484.    In  October  2018,  we  entered  into  the  APADAZ
License Agreement with KVK, pursuant to which we granted an exclusive license to KVK to commercialize APADAZ in the United States We cannot guarantee that either
Commave or KVK will be able to successfully commercialize AZSTARYS or any of our product candidates covered under the KP415 License Agreement, or APADAZ, or that
we will ever receive any payments under the APADAZ License Agreement from commercial sales of APADAZ or any future payments under the KP415 License Agreement.
We also do not know when, if ever, any other product candidate will be commercially available. Accordingly, we will need to continue to rely on additional financing to achieve
our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all. To the extent that we raise additional capital through the sale of
equity or debt, the terms of these securities may restrict our ability to operate. If we raise additional funds through collaborations, strategic alliances or marketing, distribution
or licensing arrangements with third parties, we may be required to relinquish valuable rights. If we are unable to raise capital when needed or on attractive terms, we could be
forced to delay, reduce or altogether cease our research and development programs or future commercialization efforts.

Recent Financial Developments

In January and February 2021, we undertook a series of transactions to regain our Nasdaq Capital Market listing and improve our balance sheet.  These included a reverse stock
split, an underwritten public offering, or the Public Offering, a restructuring or our debt and ultimately a payoff of all remaining debt and a transaction in which we induced the
holders of some of the warrants we issued in the public offering to exercise those warrants for cash.

Reverse Stock Split and Nasdaq Relisting

Effective May 21, 2020, our common stock had been delisted from The Nasdaq Capital Market and we began listing on the OTC Markets Venture Market under the symbol
“KMPH”. In anticipation of the Public Offering, we determined we would need to regain our Nasdaq listing.

In order to relist our common stock on The Nasdaq Capital Market, our common stock was required to satisfy the initial listing standards of the Nasdaq Capital Market, which
including  among  others,  that  we  have  stockholders’  equity  of  at  least  $5.0  million,  a  market  value  of  unrestricted  publicly  held  shares  of  at  least  $15.0  million,  at  least
1.0  million  unrestricted  publicly  held  shares,  at  least  300  unrestricted  round  lot  stockholders,  at  least  three  market  makers  and  a  bid  price  of  at  least  $4.00  per  share,  or,
collectively, the Nasdaq Listing Requirements. Accordingly, on December 23, 2020, we effectuated a 1-for-16 reverse stock split of our common stock in order to satisfy the bid
price component of the Nasdaq Listing Requirements.

On January 7, 2021, our common stock was approved for listing on The Nasdaq Capital Market. Our common stock began trading on The Nasdaq Capital Market on January 8,
2021 under the ticker symbol “KMPH”.

Debt Restructuring

In anticipation of the Public Offering, and to meet the Nasdaq Listing Requirements, we agreed in December 2020 to restructure our outstanding senior secured convertible
notes  issued  in  December  2019  and  January  2020,  or  the  Senior  Secured  Notes,  in  the  aggregate  principal  amount  of  $60.8  million  and  the  senior  secured  convertible
promissory  note  held  by  Deerfield  Private  Design  Fund  III,  L.P.,  or  Deerfield,  in  the  principal  amount  of  $7.5  million,  or  the  Deerfield  Note,  and,  collectively  the  Senior
Secured Notes, the Facility Notes. The total outstanding principal and accrued interest under the Facility Notes was $69.4 million as of December 31, 2020.

Under the terms of the agreement we entered into with our lenders in connection with this debt restructuring, which we refer to as the December 2020 Exchange Agreement, on
January 12, 2021, in connection with the closing of our Public Offering, we:

● exchanged $31.5 million of the outstanding principal and accrued interest on the Facility Notes for (i) 31,476.98412 shares of our Series B-2 convertible preferred stock,

and (ii) warrants exercisable for 3,632,019 shares of our common stock, or the Exchange Warrants; and

  ● made a payment of $30.3 million, or the Debt Payment, in partial repayment of the remaining outstanding principal and accrued interest on the Facility Notes.

Each share of Series B-2 convertible preferred stock issued pursuant to the December 2020 Exchange Agreement has a stated value of $1,000 and is convertible into shares of
our common stock at any time following the earlier of March 2, 2021 or our public announcement of the outcome of the FDA’s review of our AZSTARYS NDA at the option of
the holder thereof, subject to specified limits, at a conversion price of $6.4999. The shares of Series B-2 convertible preferred stock issued under the December 2020 Exchange
Agreement are convertible into an aggregate of 4,842,690 shares of our common stock.

The Exchange Warrants have substantially the same terms and conditions as the warrants sold by us in our January 2021 underwritten offering.

Following the completion of these transactions, the aggregate balance of principal and accrued interest remaining outstanding under the Facility Notes was approximately $7.6
million. With respect to this remaining outstanding balance under the Facility Notes, the December 2020 Exchange Agreement amended the terms of that debt to provide that:

  ● the maturity date was changed to March 31, 2023, and the debt is prepayable upon specified conditions; and

  ● interest would accrue at the rate of 6.75% per annum, payable quarterly, would be added to principal until June 30, 2021, and then be payable in cash thereafter.

In connection with the closing of the transactions contemplated under the December 2020 Exchange Agreement, we filed an amended and restated certificate of designation
with  the  Secretary  of  State  of  Delaware  in  order  to  modify  the  terms  of  our  authorized,  but  unissued,  shares  of  Series  B-2  convertible  preferred  stock  to  reflect  those
contemplated under the December 2020 Exchange Agreement.

We also filed a registration statement to register for resale under the Securities Act the shares of common stock issuable upon conversion of the shares of Series B-2 convertible
preferred stock and exercise of the Exchange Warrants.

Public Offering

On  January  8,  2021,  we    issued  and  sold  6,765,463  shares  of    our  common  stock,  pre-funded  warrants  to  purchase  926,844  shares  of  our  common  stock  and  warrants  to
purchase 7,692,307 shares of our common stock at an exercise price per share of $6.50 in the Public Offering. In addition, we granted the underwriter for the Public Offering an
option to purchase, for a period of 45 days, up to an additional 1,153,846 shares of our common stock and/or warrants to purchase up to an additional 1,153,846 shares of our
common stock. On January 8, 2021, the underwriter exercised its over-allotment option, in part, for warrants to purchase 754,035 shares of our common stock. On January 12,
2021, we closed the Public Offering. Further, on February 1, 2021, the underwriter again exercised its over-allotment option, in part, to purchase 374,035 shares of our common
stock. On February 3, 2021, we closed the underwriter's partial exercise of its over-allotment option.

The  aggregate  gross  proceeds  to  us  from  the  Public  Offering,  including  from  the  exercises  by  the  underwriter  of  its  over-allotment  option,  totaled  $52.4  million,  before
deducting underwriting discounts and commissions and offering expenses payable by us.

December 2020 Exchange Agreement Amendment

On  January  12,  2021,  in  connection  with  the  transactions  contemplated  by  the  December  2020  Exchange  Agreement,  we  entered  into  an  Amendment  to  Senior  Secured
Convertible Notes and Amendment to Warrant, or the January 2021 Amendment, with Deerfield and Deerfield Special Situations Fund, LP, collectively the Deerfield Holders.
The January 2021 Amendment modified certain specified terms of (i) the Facility Notes and (ii) the warrant held be Deerfield, issued on June 2, 2014, or the Deerfield Warrant,
to, among other things, exclude the transactions contemplated by the December 2020 Exchange Agreement and issuance of securities pursuant to the Underwriting Agreement
from the anti-dilution provisions of the Facility Notes and the Deerfield Warrant.

Warrant Exercise Inducement Letters and Issuance of Warrants

On January 26, 2021, we entered into warrant exercise inducement offer letters, or the Inducement Letters, with certain holders of warrants issued in the Public Offering, or the
Existing  Warrants,  and  collectively,  the  Exercising  Holders,  pursuant  to  which  such  holders  exercised  for  cash  their  Existing  Warrants  to  purchase  6,620,358  shares  of  our
common  stock  in  exchange  for  new  warrants,  or  the  Inducement  Warrants,  on  substantially  the  same  terms  as  the  Existing  Warrants,  except  as  set  forth  in  the  following
sentence, to purchase up to 7,944,430 shares of our common stock, which was equal to 120% of the number of shares of our common stock issued upon exercise of the Existing
Warrants. The purchase price of the Inducement Warrants was $0.125 per share underlying each Inducement Warrant, and the Inducement Warrants have an exercise price of
$6.36 per share. We received aggregate gross proceeds of $44.0 million from the exercise of the Existing Warrants by the Exercising Holders and the sale of the Inducement
Warrants.

We also filed a registration statement on Form S-3 covering the resale of the shares of our common stock issued or issuable upon the exercise of the Inducement Warrants which
was declared effective on February 16, 2021.

Payoff of Facility Agreement Notes and Termination of Facility Agreement

On February 8, 2021, we entered into a payoff letter with the Facility Note holders, pursuant to which we agreed to pay off and thereby terminate the Facility Agreement.

Pursuant to the payoff letter, we paid a total of $8.0 million to the Facility Note holders, representing the principal balance, accrued interest outstanding and a prepayment fee in
repayment of our outstanding obligations under the Facility Agreement.

Pursuant to the payoff letter, all outstanding indebtedness and obligations of us owing to the Facility Note holders under the Facility Agreement have been paid in full. The
Facility Agreement and the notes thereunder, as well as the security interests in the assets of us securing the Facility Agreement and note obligations, have been terminated.

Third-Party Agreements

KP415 License Agreement

In  September  2019,  we  entered  into  the  KP415  License  Agreement  with  Commave.  Under  the  KP415  License  Agreement,  we  granted  to  Commave  an  exclusive,
worldwide  license  to  develop,  manufacture  and  commercialize  our  product  candidates  containing  SDX  and  d-MPH,  including AZSTARYS,  KP484,  and,  at  the  option  of
Commave, KP879, KP922 or any other product candidate developed by us containing SDX and developed to treat ADHD or any other central nervous system disorder, or the
Additional Product Candidates and, collectively with AZSTARYS and KP484, the Licensed Product Candidates.

Under  the  terms  of  the  KP415  License  Agreement,  we  granted  Commave  an  exclusive,  worldwide  license  to  commercialize  and  develop  the  Licensed  Product  Candidates;
provided  that  such  license  shall  apply  to  an  Additional  Product  Candidates  only  if  Commave  exercises  its  option  under  the  KP415  License  Agreement  related  thereto.  If
Commave exercises its option related to any Additional Product Candidate under the KP415 License Agreement, the parties are obligated to negotiate in good faith regarding
the economic terms of such Additional Product Candidate. We also granted to Commave a right of first refusal to acquire, license or commercialize any Additional Product
Candidate, with such right of first refusal expiring upon the acceptance of a new drug application for such Additional Product Candidate. We also granted Commave a right of
first negotiation and a right of first refusal, subject to specified exceptions, for any assignment of our rights under the KP415 License Agreement.

Pursuant  to  the  KP415  License  Agreement,  Commave  paid  us  an  upfront  payment  of  $10.0  million  and  agreed  to  pay  up  to  $63.0  million  in  milestone  payments  upon  the
occurrence of specified regulatory milestones related to AZSTARYS, including FDA approval and specified conditions with respect to the final approval label, and KP484. As a
result  of  the  FDA’s  approval  of  the  AZSTARYS  NDA,  we  have  earned  a  regulatory  milestone  payment  following  FDA  approval  as  provided  under  the  KP415  License
Agreement,  and  we  are  working  with  Commave  to  evaluate  the  related  provisions  and  amounts.  In  addition,  Commave  agreed  to  make  additional  payments  upon  the
achievement of specified U.S. sales milestones of up to $420.0 million in the aggregate, depending, among other things, on timing of approval for AZSTARYS and its final
approved  label,  if  any.  In  May  2020,  the  FDA  accepted  our  NDA  for  AZSTARYS.  Per  the  KP415  License  Agreement,  we  received  a  regulatory  milestone  payment  of
$5.0 million following the FDA’s acceptance of the AZSTARYS NDA. Further, Commave will pay us quarterly, tiered royalty payments ranging from a percentage in the high
single digits to the mid-twenties of Net Sales (as defined in the KP415 License Agreement) in the United States and a percentage in the low to mid-single digits of Net Sales in
each  country  outside  the  United  States,  in  each  case  subject  to  specified  reductions  under  certain  conditions  as  described  in  the  KP415  License  Agreement.  Commave  is
obligated to make such royalty payments on a product-by-product basis until expiration of the Royalty Term (as defined in the KP415 License Agreement) for the applicable
product.

Commave agreed to be responsible for and reimburse us for all of development, commercialization and regulatory expenses for the Licensed Product Candidates, subject to
certain limitations as set forth in the KP415 License Agreement.

The KP415 License Agreement will continue on a product-by-product basis (i) until expiration of the Royalty Term for the applicable Licensed Product Candidate in the United
States  and  (ii)  perpetually  for  all  other  countries.  Commave  may  terminate  the  KP415  License  Agreement  at  its  convenience  upon  prior  written  notice  prior  to  regulatory
approval of any Licensed Product Candidate or upon prior written notice after regulatory approval of any Licensed Product Candidate. We may terminate the KP415 License
Agreement in full if Commave, any of its sublicensees or any of its or their affiliates challenge the validity of any Licensed Patent (as defined in the KP415 License Agreement)
and such challenge is not required under a court order or subpoena and is not a defense against a claim, action or proceeding asserted by us. Either party may terminate the
KP415  License  Agreement  (i)  upon  a  material  breach  of  the  KP415  License  Agreement  by  the  other  party,  subject  to  a  cure  period,  or  (ii)  if  the  other  party  encounters
bankruptcy or insolvency. Upon a Serious Material Breach (as defined in the KP415 License Agreement) by us, subject to a cure period, Commave may choose not to terminate
the KP415 License Agreement and instead reduce the milestone and royalty payments owed to us. Upon termination, all licenses and other rights granted by us to Commave
pursuant to the KP415 License Agreement would revert to us. During the term of the KP415 License Agreement, we may not develop or commercialize any Competing Product
(as defined in the KP415 License Agreement).

The  KP415  License  Agreement  also  established  a  joint  steering  committee,  which  monitors  progress  of  the  development  of  both  AZSTARYS  and  KP484.  Subject  to  the
oversight of the joint steering committee, we otherwise retain all responsibility for the conduct of all regulatory activities required to obtain new drug application approval of
AZSTARYS and KP484; provided that Commave shall be the sponsor of any clinical trials conducted by us on behalf of Commave.

APADAZ License Agreement

In October 2018, we entered into the APADAZ License Agreement with KVK pursuant to which we have granted an exclusive license to KVK to conduct regulatory activities
for, manufacture and commercialize APADAZ in the United States.

Pursuant to the APADAZ License Agreement, KVK has agreed to pay us certain payments and cost reimbursements of an estimated $3.4 million, which includes a payment of
$2.0 million within 10 days of the achievement of a specified milestone related to the initial formulary adoption of APADAZ, or the Initial Adoption Milestone. In addition,
KVK has agreed to make additional payments to us upon the achievement of specified sales milestones of up to $53.0 million in the aggregate. Further, we and KVK will share
the quarterly net profits of APADAZ by KVK in the United States at specified tiered percentages, ranging from us receiving 30% to 50% of net profits, based on the amount of
net sales on a rolling four quarter basis. We are responsible for a portion of commercialization and regulatory expenses for APADAZ until the Initial Adoption Milestone is
achieved, after which KVK will be responsible for all expenses incurred in connection with commercialization and maintaining regulatory approval in the United States.

The APADAZ License Agreement will terminate on the later of the date that all of the patent rights for APADAZ have expired in the United States or KVK’s cessation of
commercialization of APADAZ in the United States. KVK may terminate the APADAZ License Agreement upon 90 days written notice if a regulatory authority in the United
States orders KVK to stop sales of APADAZ due to a safety concern. In addition, after the third anniversary of the APADAZ License Agreement, KVK may terminate the
APADAZ License Agreement without cause upon 18 months prior written notice. We may terminate the APADAZ License Agreement if KVK stops conducting regulatory
activities for or commercializing APADAZ in the United States for a period of six months, subject to specified exceptions, or if KVK or its affiliates challenge the validity,
enforceability or scope of any licensed patent under the APADAZ License Agreement. Both parties may terminate the APADAZ License Agreement (i) upon a material breach
of the APADAZ License Agreement, subject to a 30-day cure period, (ii) the other party encounters bankruptcy or insolvency or (iii) if the Initial Adoption Milestone is not
achieved. Upon termination, all licenses and other rights granted by us to KVK pursuant to the APADAZ License Agreement would revert to us.

The APADAZ License Agreement also established a joint steering committee, which monitors progress of the commercialization of APADAZ.

Other Third-Party Agreements

Under our March 2012 asset purchase agreement with Shire, Shire had a right of first refusal to acquire, license or commercialize AZSTARYS and KP484. In early 2019, Shire
was acquired by Takeda Pharmaceutical Company, Ltd, or Takeda, to whom this right of first refusal was transferred at that time. Takeda did not exercise this right of first
refusal in connection with our entry into the KP415 License Agreement.

Under our March 2012 termination agreement with Aquestive, Aquestive has the right to receive a royalty amount equal to 10% of any value generated by AZSTARYS, KP484
or  KP879,  and  any  product  candidates  containing  SDX,  including  royalty  payments  on  any  license  of  AZSTARYS,  KP484  or  KP879,  the  sale  of  AZSTARYS,  KP484  or
KP879 to a third party, the commercialization of AZSTARYS, KP484 or KP879 and the portion of any consideration that is attributable to the value of AZSTARYS, KP484 or
KP879 and paid to us or our stockholders in a change of control transaction. In connection with the KP415 License Agreement, we paid Aquestive a royalty equal to 10% of the
upfront license payment we received in the third quarter of 2019 and the regulatory milestone payment we received in the second quarter of 2020.

In July 2020, we entered into the Corium Consulting Agreement under which Corium engaged us to guide the product development and regulatory activities for certain current
and potential future products in their portfolio, as well as continue supporting preparation for the potential commercial launch of AZSTARYS. Under the Corium Consulting
Agreement, we are entitled to receive payments from Corium of up to $15.6 million, $13.6 million of which will be paid in quarterly installments through March 31, 2022. The
remaining $2.0 million is conditioned upon the achievement of a specified regulatory milestone related to Corium’s product portfolio. Corium also agreed to be responsible for
and reimburse us for all development, commercialization and regulatory expenses incurred as part of the performance of the consulting services.

Components of our Results of Operations

Revenue

Our  commercial  revenue,  if  any,  will  be  derived  from  sales  of  AZSTARYS, APADAZ  or  any  of  our  other  product  candidates  for  which  we  obtain  regulatory  approval.  We
expect that our only source of revenues will be through payments arising from our license agreements with Commave and KVK, and through any other future arrangements
related to one of our other product candidates. To date, we have generated revenue from the KP415 License Agreement in the form of the non-refundable upfront payment of
$10.0  million,  of  which  we  paid  Aquestive  $1.0  million  as  a  royalty  payment,  a  regulatory  milestone  payment  of  $5.0  million  following  the  FDA’s  acceptance  of  the
AZSTARYS NDA, of which we paid Aquestive $0.5 million as a royalty payment, reimbursement of out-of-pocket third-party research and development costs and payments
related to the performance of consulting services. In addition, we have generated revenue under the Corium Consulting Agreement and other consulting arrangements for the
performance of consulting services as well as reimbursement of out-of-pocket third-party costs associated with those services. We cannot guarantee that either Commave or
KVK will be able to successfully commercialize AZSTARYS or our product candidates covered under the KP415 License Agreement, or APADAZ, or that we will ever receive
any payments under the KP415 License Agreement from commercial sales of APADAZ or any future payments under the APADAZ License Agreement. We also do not know
when, if ever, any other product candidate will be commercially available.

Royalties and Contract Costs

The components of our royalties and contract costs are royalties and expenses directly attributable to revenue. To date, we have generated revenue from the KP415 License
Agreement  in  the  form  of  the  non-refundable  upfront  payment  of  $10.0  million,  a  regulatory  milestone  payment  of  $5.0  million  following  the  FDA’s  acceptance  of  the
AZSTARYS NDA, reimbursement of out-of-pocket third-party research and development costs and payments related to the performance of consulting services. In connection
with  the  KP415  License  Agreement,  we  paid Aquestive  a  royalty  equal  to  10%  of  the  upfront  license  payment  we  received  in  the  third  quarter  of  2019  and  10%  of  the
regulatory milestone, related to the acceptance of the NDA, we received in the second quarter of 2020. In addition, we capitalized incremental costs directly attributable to the
KP415 License Agreement, these costs are amortized to royalties and contract costs as revenue is recognized.

Operating Expenses

We  classify  our  operating  expenses  into  three  categories:  research  and  development  expenses,  general  and  administrative  expenses  and  severance  expense.  Salaries  and
personnel-related costs, including benefits, bonuses and stock-based compensation expense, comprise a significant component of each of these expense categories. We allocate
expenses  associated  with  our  facilities,  information  technology  costs  and  depreciation  and  amortization  between  research  and  development  expenses  and  general  and
administrative expenses based on employee headcount and the nature of work performed by each employee.

91

 
 
 
 
 
 
 
 
 
Research and Development Expense

Research and development expense consists of expenses incurred while performing research and development activities to discover and develop potential product candidates.
This  includes  conducting  preclinical  studies  and  clinical  trials,  manufacturing  development  efforts  and  activities  related  to  regulatory  filings  for  product  candidates.  We
recognize research and development expenses as they are incurred. Our research and development expense primarily consists of:

  ● salaries and personnel-related costs, including benefits and any stock-based compensation, for our scientific personnel performing research and development activities;

  ● costs related to executing preclinical studies and clinical trials;

  ● fees paid to consultants and other third parties who support our product candidate development;

  ● other costs in seeking regulatory approval of our products; and

  ● allocated facility-related costs and overhead.

We  typically  use  our  employee,  consultant  and  infrastructure  resources  across  our  development  programs.  We  track  outsourced  development  costs  by  product  candidate  or
development program, but we do not allocate personnel costs, other internal costs or external consultant costs to specific product candidates or development programs.

The following table summarizes our research and development costs for the years ended December 31, 2020 and 2019 (in thousands):

We  anticipate  that  our  research  and  development  expense  will  fluctuate  for  the  foreseeable  future  as  we  continue  our  efforts  to  advance  the  development  of  our  product
candidates, subject to the availability of additional funding. In accordance with the KP415 License Agreement, Commave has also agreed to be responsible and reimburse us for
all of development, commercialization and regulatory expenses for the Licensed Product Candidates, subject to certain limitations as set forth in the KP415 License Agreement.

The successful commercialization of AZSTARYS, APADAZ, and any of our other product candidates that may be approved and the development of our product candidates is
highly  uncertain.  At  this  time,  we  cannot  reasonably  estimate  the  nature,  timing  or  costs  required  to  commercialize  AZSTARYS,  APADAZ,  or  any  of  our  other  product
candidates,  if  approved,  and  complete  the  remaining  development  of  any  product  candidates.  This  is  due  to  the  numerous  risks  and  uncertainties  associated  with  the
commercialization and development of our products and product candidates.

General and Administrative Expense

General and administrative expense consists primarily of salaries and personnel-related costs, including employee benefits and any stock-based compensation, for employees
performing functions other than research and development. This includes personnel in executive, finance, human resources and administrative support functions. Other general
and administrative expenses include facility-related costs not otherwise allocated to research and development expense, professional fees for auditing, tax and legal services,
expenses associated with obtaining and maintaining patents, consulting costs and costs of our information systems.

We expect that our general and administrative expense will fluctuate as we continue to operate as a public reporting company and continue to develop our product candidates.
We believe that these fluctuations will likely include costs related to the hiring of additional personnel and fees for outside consultants, lawyers and accountants. We also expect
to  continue  to  incur  costs  to  comply  with  corporate  governance,  internal  controls,  investor  relations,  disclosure  and  similar  requirements  applicable  to  public  reporting
companies.

Severance Expense

Severance  expense  in  2020  consisted  of  severance  payments  and  stock-based  compensation  paid  to  our  former  chief  business  officer  who  ceased  to  serve  in  this  role  in
February 2020. We had no severance expense in 2019.

Other (Expense) Income

Other (expense) income consists primarily of non-cash costs associated with fair value adjustments to our derivative and warrant liability and amortization of debt issuance
costs and debt discount to interest expense. Other (expense) income also includes interest expense incurred on our outstanding borrowings, as well as, interest and other
income consisting primarily of interest earned on investments. These items are unrelated to our core business and thus are recognized as other (expense) income in our
statements of operations.

Income Tax Benefit

Income tax benefit consists of refundable state income tax credits. To date, we have not been required to pay U.S. federal or state income taxes because we have not generated
taxable income. We have received state income tax credits related to our qualified research activities in Iowa.

Net loss for the year ended December 31, 2020 was $12.8 million, a decrease of $11.8 million compared to net loss for the year ended December 31, 2019 of $24.5 million.
The decrease was primarily attributable to a decrease in loss from operations of $14.7 million, partially offset by a change in non-cash fair value adjustment from income of
$2.0 million in 2019 to expense of $0.2 million in 2020, related to changes to the derivative and warrant liability, and an increase in net interest expense and other items of
$0.8 million.

Revenue

Revenue  increased  by  $0.4  million,  from  $12.8  million  for  the  year  ended  December  31,  2019,  to  $13.3  million  for  the  year  ended  December 31, 2020.  This  increase  was
primarily attributable to an increase in consulting revenue of $5.3 million, primarily related to the Corium Consulting Agreement, and an increase in reimbursement revenue of
$0.2 million, partially offset by a decrease in licensing and milestone revenue of $5.0 million, due to the one-time non-refundable upfront payment of $10.0 million received in
2019 compared to, the $5.0 million payment received related to the regulatory milestone in 2020 both pursuant to the KP415 License Agreement.

Royalties and Contract Costs

Royalties and contract costs decreased by $1.6 million, from $2.9 million for the year ended December 31, 2019, to $1.3 million for the year ended December 31, 2020. This
decrease  was  primarily  attributable  to  a  decrease  in  royalties  due  to  Aquestive  of  $0.5  million  related  to  the  upfront  and  milestone  payments  we  received  in  2019  and
2020 discussed above and a decrease in the amortization of capitalized contract costs which were directly attributable to the revenue recognized of $1.1 million.

Research and Development

Research and development expenses decreased by $10.6 million, from $19.4 million for the year ended December 31, 2019, to $8.8 million for the year ended December 31,
2020. This decrease was primarily attributable to a decrease in net third-party research and development costs.

General and Administrative

General and administrative expenses decreased by $2.9 million, from $10.8 million for the year ended December 31, 2019, to $7.9 million for the year ended December 31,
2020. This decrease was primarily attributable to a decrease in professional fees and personnel-related costs.  

Severance Expense

Severance expense of $0.8 million was recognized for the year ended December 31, 2020 due to the termination of our chief business officer in February 2020. Severance
expense is comprised of $0.4 million of personnel and other related charges and $0.4 million of stock compensation expense related to the acceleration of vesting on certain
stock options upon employee termination. We had no severance expense for the year ended December 31, 2019.

Other (Expense) Income

Other expenses increased by $3.0 million, from $4.2 million for the year ended December 31, 2019, to $7.2 million for the year ended December 31, 2020.  This  period-to-
period increase in expense was primarily attributable to a change in non-cash fair value adjustment from income of $2.0 million in 2019 to expense of $0.2 million in 2020
related to our derivative and warrant liability and an increase in net interest expense and other items of $0.8 million.

Comparison for Years Ended December 31, 2019 and 2018

For a discussion and analysis of changes in financial condition and results of operations for the year ended December 31, 2019 as compared to the year ended December 31,
2018, refer to our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, filed with the SEC on February 28, 2020.

Liquidity and Capital Resources

Sources of Liquidity

Through December 31, 2020, we have funded our research and development and operating activities primarily through the issuance of debt, private placements of redeemable
convertible preferred stock and the sale of common stock in our initial public offering, at-the-market offering, underwritten public offerings, through our purchase agreements
with  Lincoln  Park  Capital  LLC,  or  Lincoln  Park,  and  from  revenue  received  under  the  KP415  License  Agreement,  the  Corium  Consulting  Agreement  and  other  consulting
arrangements. As of December 31, 2020, we had cash and cash equivalents of $4.2 million and restricted cash of $0.1 million.

In February 2019, we entered into a purchase agreement for an equity line of credit, or the 2019 ELOC Agreement, with Lincoln Park, which provided that, upon the terms and
subject  to  the  conditions  and  limitations  set  forth  therein,  we  may  sell  to  Lincoln  Park  up  to  $15.0  million  of  shares  of  our  common  stock,  from  time  to  time  over  the  36-
month term of the 2019 ELOC Agreement, and upon execution of the 2019 ELOC Agreement we issued an additional 7,512 shares of our common stock to Lincoln Park as
commitment shares in accordance with the closing conditions contained within the 2019 ELOC Agreement. In February 2020, upon entering into a new purchase agreement for
an equity line of credit, or the 2020 ELOC Agreement, with Lincoln Park, we terminated the 2019 ELOC Agreement. As a result, we will not make any future sales under the
2019 ELOC Agreement. Through the date of termination, we sold 212,579 shares of our common stock (exclusive of the 7,512 commitment shares) to Lincoln Park under the
2019 ELOC Agreement for approximately $5.4 million in gross proceeds.

In September 2019, we entered into the KP415 License Agreement with Commave and Commave paid us a non-refundable upfront payment of $10.0 million. In May 2020, the
FDA accepted our NDA for AZSTARYS. Per the KP415 License Agreement, we received a regulatory milestone payment of $5.0 million following the FDA’s acceptance of
the  AZSTARYS  NDA.  In  July  2020,  we  entered  into  the  Corium  Consulting  Agreement  under  which  Corium  engaged  us  to  guide  the  product  development  and  regulatory
activities  for  certain  current  and  potential  future  products  in  their  portfolio,  as  well  as  continue  supporting  preparation  for  the  potential  commercial  launch  of  AZSTARYS.
Under the Corium Consulting Agreement, we are entitled to receive payments from Corium of up to $15.6 million, $13.6 million of which will be paid in quarterly installments
through March 31, 2022. The remaining $2.0 million is conditioned upon the achievement of a specified regulatory milestone related to Corium’s product portfolio. Corium
also  agreed  to  be  responsible  for  and  reimburse  us  for  all  development,  commercialization  and  regulatory  expenses  incurred  as  part  of  the  performance  of  the  consulting
services.

95

 
 
 
 
 
 
 
 
 
In February 2020, we entered into the 2020 ELOC Agreement, with Lincoln Park, which provided that, upon the terms and subject to the conditions and limitations set forth
therein, we may sell to Lincoln Park up to $4.0 million of shares of our common stock, from time to time over the 12-month term of the 2020 ELOC Agreement, and upon
execution of the 2020 ELOC Agreement we issued an additional 19,289 shares of our common stock to Lincoln Park as commitment shares in accordance with the closing
conditions contained within the 2020 ELOC Agreement. In May 2020, we reached the maximum allowable shares to be issued under the Current Registration Statement of
579,260 shares and therefore we cannot issue additional shares under the 2020 ELOC Agreement. As of December 31, 2020, we have sold 559,971 shares of common stock
(exclusive of the 19,289 commitment shares previously issued to Lincoln Park) under the 2020 ELOC Agreement for approximately $2.3 million in gross proceeds.

We have had recurring negative operating cash flows and, as of December 31, 2020, had an accumulated deficit of $258.5 million. We anticipate that we will continue to incur
minimal positive net cash flows from operations or negative net cash flows from operations for at least the next several years. We expect that our sources of revenue will be
through payments arising from our license agreements with Commave and KVK, or through our Corium Consulting Agreement, and other potential consulting arrangements
and any other future arrangements related to one of our other product candidates.

In January 2021, we completed the Public Offering. The aggregate gross proceeds to us from the Public Offering, including from the exercises by the underwriter of its over-
allotment option, totaled $52.4 million, before deducting underwriting discounts and commissions and offering expenses payable by us.

In January 2021, we entered into the Inducement Letters. We received aggregate gross proceeds of $44.0 million from the exercise of the Existing Warrants by the Exercising
Holders and the sale of the Inducement Warrants.

On April 23, 2020, we received proceeds of $0.8 million from a loan, or the PPP Loan, under the Paycheck Protection Program, or the PPP, of the recently enacted Coronavirus
Aid, Relief, and Economic Security Act, or the CARES Act, a portion of which may be forgiven, which we used to retain current employees, maintain payroll and make lease
and utility payments. The PPP Loan matures on April 23, 2022 and bears annual interest at a rate of 1.0%. Payments of principal and interest on the PPP Loan are deferred for
the first 16 months of the PPP Loan term. Thereafter, we could be required to pay the lender equal monthly payments of principal and interest.

The CARES Act and the PPP provide a mechanism for forgiveness of up to the full amount borrowed. Under the PPP, we may apply for and be granted forgiveness for all or
part of the PPP Loan. The amount of loan proceeds eligible for forgiveness was originally based on a formula that takes into account a number of factors, including the amount
of loan proceeds used by us during the 24-week period after the loan origination for certain purposes, including payroll costs, interest on certain mortgage obligations, rent
payments  on  certain  leases,  and  certain  qualified  utility  payments,  provided  that  at  least  60%  of  the  loan  amount  was  used  for  eligible  payroll  costs.  Subject  to  the  other
requirements and limitations on loan forgiveness, only loan proceeds spent on payroll and other eligible costs during the covered 24-week period qualify for forgiveness. We
have applied for forgiveness under the provisions of the PPP loan and are awaiting a decision by the SBA.

Convertible Debt

As of December 31, 2020, we had $68.2 million of convertible notes outstanding, consisting of senior secured convertible promissory notes issued, under the Deerfield Facility
Agreement with Deerfield. Subsequent to December 31, 2020, we repaid in full the convertible notes and terminated the Deerfield Facility Agreement.

Deerfield Facility Agreement

In June 2014, we entered into the Deerfield Facility Agreement as a $60.0 million multi-tranche credit facility with Deerfield. At the time we entered into the Deerfield Facility
Agreement, we borrowed the first tranche, which consisted of a $15.0 million term note and the $10.0 million convertible note, or the Deerfield Convertible Note.

The Deerfield Convertible Note originally bore interest at 9.75% per annum, but was subsequently reduced to 6.75%. Interest accrued on the outstanding balance under the
Deerfield Convertible Note was due quarterly in arrears. We originally had to repay one-third of the outstanding principal amount of the Deerfield Convertible Note on the
fourth and fifth anniversaries of the Deerfield Facility Agreement (June 2018 and June 2019). In June 2018, Deerfield agreed to convert the $3,333,333 of the principal amount
then due, plus $168,288 of accrued interest, into 37,410 shares of our common stock. In September 2019, we entered into an amendment with Deerfield in order to (i) reduce
the interest rate applicable under the Deerfield Facility Agreement from 9.75% to 6.75%, (ii) provide for “payment in kind” of interest on the Loans (as defined in the Deerfield
Facility  Agreement),  and  (iii)  defer  the  Loan  payments  due  pursuant  to  the  Deerfield  Facility  Agreement  until  June  1,  2020.  In  December  2019,  we  entered  into  another
amendment  with  Deerfield  in  order  to  (i)  defer  the  Loan  payments  due  pursuant  to  the  Deerfield  Facility  Agreement  until  March  31,  2021  and  (ii)  allow  for  the  entries  of
additional debt and debt holders under the Deerfield Facility Agreement (as discussed in more detail below).

Pursuant  to  the  Deerfield  Facility  Agreement,  we  issued  to  Deerfield  1,923,077  shares  of  our  Series  D  redeemable  convertible  preferred  stock,  or  Series  D  Preferred,  as
consideration  for  the  loans  provided  to  us  thereunder.  Upon  closing  of  our  initial  public  offering,  these  shares  of  Series  D  Preferred  reclassified  into  16,025  shares  of  our
common stock.

We  also  issued  to  Deerfield  the  Deerfield  Warrant  to  purchase  14,423,076  shares  of  our  Series  D  Preferred  at  an  initial  exercise  price  of  $0.78  per  share,  or  the  Deerfield
Warrant. Upon closing of our initial public offering, this warrant converted into a warrant exercisable for 120,192 shares of our common stock at an exercise price of $93.60 per
share.

97

 
 
 
 
 
 
 
 
 
2021 Notes

In February 2016, we issued our 5.50% Senior Convertible Notes due 2021, or the 2021 Notes, in aggregate principal amount of $86.3 million. The 2021 Notes were originally
issued to Cowen and Company and RBCCM LLC as representatives of the several initial purchasers, who subsequently resold the 2021 Notes to qualified institutional buyers in
reliance on the exemption from registration provided by Rule 144A under the Securities Act.

The 2021 Notes were issued pursuant to an indenture, dated as of February 9, 2016, or the indenture, between us and U.S. Bank National Association, as trustee. Interest on the
2021 Notes was payable semi-annually in cash in arrears on February 1 and August 1 of each year, beginning on August 1, 2016, at a rate of 5.50% per year. The 2021 Notes
originally matured on February 1, 2021 unless earlier converted or repurchased.

As described in more detail below, in multiple exchanges occurring in October 2018, December 2019 and January 2020, all outstanding 2021 Notes were exchanged by the
holders thereof for either shares of our common stock or the December 2019 Notes and January 2020 Note issued under the terms of the Deerfield Facility Agreement.

2021 Note Exchanges

2021 Note Exchange Effected in October 2018

In  October  2018,  we  entered  into  an  exchange  agreement,  or  the  October  2018  Exchange  Agreement,  with  the  Deerfield  Lenders.  Under  the  October  2018  Exchange
Agreement, the Deerfield Lenders exchanged an aggregate of $9,577,000 principal amount of our 2021 Notes for an aggregate of 9,577 shares of our Series A Convertible
Preferred Stock, par value $0.0001, or the Series A Preferred Stock.

As a condition to closing of the October 2018 Exchange Agreement, we filed a Certificate of Designation of Preferences, Rights and Limitations of Series A Convertible
Preferred Stock, or the Series A Certificate of Designation, with the Secretary of State of the State Delaware, setting forth the preferences, rights and limitations of the Series
A Preferred Stock.

Each  share  of  Series  A  Preferred  Stock  has  an  aggregate  stated  value  of  $1,000  and  is  convertible  into  shares  of  our  common  stock  at  a  price  equal  to  $48.00  per  share
(subject  to  adjustment  to  reflect  stock  splits  and  similar  events).  Immediately  following  the  exchange  under  the  October  2018  Exchange  Agreement,  an  aggregate  of
3,192,333 shares of common stock were issuable upon conversion of the Series A Preferred Stock. As of December 31, 2020, all 9,577 shares of Series A Preferred Stock

2021 Note Exchange Effected in September 2019

In  September  2019,  we  entered  into  an  Exchange  Agreement  and  Amendment  to  Facility  Agreement,  or  the  September  2019  Exchange  Agreement  with  the  Deerfield
Lenders. Under the September 2019 Exchange Agreement, we issued an aggregate of 493,742 shares of our common stock and an aggregate of 1,576 shares of our Series B-
1  Convertible  Preferred  Stock,  par  value  $0.0001  per  share,  or  the  Series  B-1  Preferred  Stock,  (such  shares  of  common  stock  and  Series  B-1  Preferred  Stock,  the  Initial
Exchange  Shares),  in  exchange  for  the  cancellation  of  an  aggregate  of  $3,000,000  principal  amount  of  the  2021  Notes.  The  September  2019  Exchange  Agreement
provided the Deerfield Lenders the option to exchange up to an additional aggregate of $27,000,000 principal amount of the 2021 Notes, or the Optional Exchange Principal
Amount, for shares of common stock or shares of our Series B-2 Convertible Preferred Stock, par value $0.0001 per share, or the Series B-2 Preferred Stock, and, together
with the Series B-1 Preferred Stock, the Series B Preferred Stock, subject to the terms and conditions set forth in the September 2019 Exchange Agreement, including limits
as to the principal amount that can be exchanged prior to specified dates therein. If the Deerfield Lenders choose to exchange any portion of the Optional Exchange Principal
Amount for shares of Series B-2 Preferred Stock, such exchange will be effected at an exchange price of $1,000 per share. If the Deerfield Lenders choose to exchange any
portion of the Optional Exchange Principal Amount for shares of common stock, such exchange will be effected at an exchange price equal to the greater of (i) $15.1904 or
(ii) the average of the volume-weighted average price of the common stock on each of the 15 trading days immediately preceding such exchange.

As  a  condition  to  closing  of  the  September  2019  Exchange  Agreement,  we  filed  a  Certificate  of  Designation  of  Preferences,  Rights  and  Limitations  of  Series  B-
1  Convertible  Preferred  Stock,  or  the  Series  B-1  Certificate  of  Designation,  and  a  Certificate  of  Designation  of  Preferences,  Rights  and  Limitations  of  Series  B-
2  Convertible  Preferred  Stock,  or  the  Series  B-2  Certificate  of  Designation,  with  the  Secretary  of  State  of  the  State  Delaware,  setting  forth  the  preferences,  rights  and
limitations of the Series B-1 Preferred Stock and the Series B-2 Preferred Stock, respectively.

Each share of Series B-1 Preferred Stock has an aggregate stated value of $1,000 and is convertible into shares of common stock at a per share price equal to $15.1904 per
share (subject to adjustment to reflect stock splits and similar events). There was an aggregate of 103,749 shares of common stock issuable upon conversion of the Series B-
1 Preferred Stock (without giving effect to the limitation on conversion described below). Each share of Series B-2 Preferred Stock has an aggregate stated value of $1,000
and is convertible into shares of common stock at a per share price equal to the greater of (i) $15.1904 (subject to adjustment to reflect stock splits and similar events), or
(ii) the average of the volume-weighted average prices of the common stock on each of the 15 trading days immediately preceding such exchange. Immediately following the
exchange under the September 2019 Exchange Agreement, there was an aggregate of 1,777,437 shares of Common Stock issuable (i) in exchange of the Optional Exchange
Principal Amount, or (ii) upon conversion of the Series B-2 Preferred Stock issuable in exchange of the Optional Exchange Principal Amount (in each case without giving
effect to the limitation on conversion described below).

The Series B Preferred Stock is convertible at any time at the option of the Deerfield Lenders; provided that the Deerfield Lenders are prohibited from converting shares of
Series B Preferred Stock into shares of common stock if, as a result of such conversion, such holders (together with certain affiliates and “group” members of such holders)
would beneficially own more than 4.985% of the total number of shares of common stock then issued and outstanding. The Series B Preferred Stock is not redeemable. In the
event of our liquidation, dissolution or winding up, the Deerfield Lenders will receive an amount equal to $0.0001 per share, plus any declared but unpaid dividends, and
thereafter will share ratably in any distribution of our assets with holders of common stock and with the holders of any shares of any other class or series of capital stock of us
entitled  to  share  in  such  remaining  assets  of  us  (including  our  Series  A  Preferred  Stock  on  an  as-converted  basis.  With  respect  to  rights  upon  liquidation,  the  Series  B
Preferred Stock ranks senior to the common stock, on parity with the Series A Preferred Stock, if any is outstanding, and junior to existing and future indebtedness. Except as
otherwise required by law (or with respect to approval of certain actions involving our organizational documents that materially and adversely affect the holders of Series B
Preferred Stock), the Series B Preferred Stock does not have voting rights. The Series B Preferred Stock is not subject to any price-based anti-dilution protections and does
not  provide  for  any  accruing  dividends,  but  provides  that  holders  of  Series  B  Preferred  Stock  will  participate  in  any  dividends  on  the  common  stock  on  an  as-
converted  basis  (without  giving  effect  to  the  limitation  on  conversion  described  above).  The  Series  B-1  Certificate  of  Designation  and  the  Series  B-2  Certificate  of
Designation  also  provide  for  partial  liquidated  damages  in  the  event  that  we  fail  to  timely  convert  shares  of  Series  B-1  Preferred  Stock  or  Series  B-2  Preferred  Stock,
respectively, into common stock in accordance with the applicable Certificate of Designation.

As of December 31, 2020, all 1,576 shares of Series B-1 Preferred Stock have been converted into 103,749 shares of common stock, and there were no shares of Series B-
2 Preferred Stock outstanding.

2021 Note Exchange Effected in December 2019

In December 2019, we entered into the December 2019 Exchange Agreement and Amendment to Facility Agreement, Senior Secured Convertible Notes and Warrants, or the
December 2019 Exchange Agreement, with the Deerfield Lenders and Delaware Street Capital Master Fund, L.P., or DSC and, collectively with the Deerfield Lenders, the
December 2019 Holders. Under the December 2019 Exchange Agreement, we issued the December 2019 Notes as senior secured convertible promissory notes under the
Deerfield Facility Agreement in the aggregate principal amount of $71,418,011 in exchange for the cancellation of an aggregate of $71,418,011 principal amount and accrued
interest of the 2021 Notes. Upon entering into the December 2019 Exchange Agreement, we agreed to pay the December 2019 Holders, in the aggregate, an interest payment
of  $745,011,  which  represents  50%  of  the  accrued  interest,  as  of  December  18,  2019,  on  the  2021  Notes  owned  by  the  December  2019  Holders.  The  remainder  of  such
interest was included in the principal amount of the December 2019 Notes.

The December 2019 Notes bear interest at 6.75% per annum. The December 2019 Notes were originally convertible into shares of our common stock at an initial conversion
price of $17.11 per share (which represents the conversion price of the 2021 Notes), subject to adjustment in accordance with the terms of the December 2019 Notes. As of
the date of issuance, the December 2019 Notes were convertible, by their terms, into an aggregate of 260,876 shares of our common stock. We subsequently amended the
December  2019  Notes  to  provide  that  such  notes  shall  be  convertible  into  shares  of  our  common  stock  at  a  conversion  price  of  $93.60  per  share  (which  represents  the
conversion price of the Deerfield Convertible Note). The conversion price of the December 2019 Notes will be adjusted downward if we issue or sell any shares of common
stock, convertible securities, warrants or options at a sale or exercise price per share less than the greater of the December 2019 Notes’ conversion price or the closing sale
price of our common stock on the last trading date immediately prior to such issuance, or, in the case of a firm commitment underwritten offering, on the date of execution of
the underwriting agreement between us and the underwriters for such offering. However, if we effect an “at the market offering” as defined in Rule 415 of the Securities Act,
of our common stock, the conversion price of the December 2019 Notes will be adjusted downward pursuant to this anti-dilution adjustment only if such sales are made at a
price less than $93.60 per share, provided that this anti-dilution adjustment will not apply to certain specified sales. Notwithstanding anything in the contrary in the December
2019 Notes, the anti-dilution adjustment of such notes shall not result in the conversion price of the December 2019 Notes being less than $0.583 per share. The December
2019 Notes are convertible at any time at the option of the holders thereof, provided that a holder of a December 2019 Note is prohibited from converting such note into
shares of our common stock if, as a result of such conversion, such holder (together with certain affiliates and “group” members) would beneficially own more than 4.985%
of the total number of shares of common stock then issued and outstanding. However, the December 2019 Note issued to DSC, due to the fact DSC was a beneficial owner of
more than 4.985% of the total number of shares of our common stock then issued and outstanding, has a beneficial ownership cap equal to 19.985% of the total number of
shares of our common stock then issued and outstanding. Pursuant to the December 2019 Notes, the December 2019 Holders have the option to demand repayment of all
outstanding principal, and any unpaid interest accrued thereon, in connection with a Major Transaction (as defined in the December 2019 Notes), which shall include, among
others,  any  acquisition  or  other  change  of  control  of  the  company;  our  liquidation,  bankruptcy  or  other  dissolution;  or  if  at  any  time  after  March  31,  2021,  shares  of  our
common  stock  are  not  listed  on  an  Eligible  Market  (as  defined  in  the  December  2019  Notes).  The  December  2019  Notes  are  subject  to  specified  events  of  default,  the
occurrence of which would entitle the December 2019 Holders to immediately demand repayment of all outstanding principal and accrued interest on the December 2019
Notes. Such events of default include, among others, failure to make any payment under the December 2019 Notes when due, failure to observe or perform any covenant
under the Deerfield Facility Agreement or the other transaction documents related thereto (subject to a standard cure period), our failure to be able to pay debts as they come
due, the commencement of bankruptcy or insolvency proceedings against us, a material judgement levied against us and a material default by us under the Deerfield Warrant,
the December 2019 Notes or the Deerfield Convertible Note.

The  December  2019  Exchange  Agreement  amends  the  Deerfield  Facility  Agreement,  in  order  to,  among  other  things,  (i)  provide  for  the  Deerfield  Facility  Agreement  to
govern the December 2019 Notes received by the December 2019 Holders pursuant to the December 2019 Exchange Agreement, (ii) extend the maturity of the Deerfield
Convertible Note from February 14, 2020 and June 1, 2020, as applicable, to March 31, 2021, (iii) defer interest payments on the Deerfield Convertible Note and December
2019  Notes  until  March  31,  2021  (which  such  interest  shall  accrue  as  ”payment-in-kind”  interest),  (iv)  designate  DSC  as  a  Lender  (as  defined  in  the  Deerfield  Facility
Agreement),  (v)  name  Deerfield  as  the  “Collateral  Agent”  for  all  Lenders  and  (vi)  modify  the  terms  and  conditions  under  which  we  may  issue  additional  pari  passu  and
subordinated indebtedness under the Deerfield Facility Agreement (subject to certain conditions specified in the Deerfield Facility Agreement).

The  December  2019  Exchange  Agreement  also  amends  and  restates  that  the  Deerfield  Convertible  Note  to  conform  the  definitions  of  “Eligible  Market”  and  “Major
Transactions”  to  the  definition  in  the  December  2019  Notes,  to  remove  provisions  that  were  only  applicable  prior  to  our  initial  public  offering  and  to  make  certain  other
changes to conform to the December 2019 Notes. The conversion price for the Deerfield Convertible Note remains $93.60 per share, subject to adjustment on the same basis
as the December 2019 Notes.

100

 
 
 
 
 
 
 
The December 2019 Exchange Agreement also amends Deerfield Warrant to conform the definitions of “Eligible Market” and “Major Transaction” in the Warrant with the
definitions of such terms in the December 2019 Notes.

In connection with entering into the December 2019 Exchange Agreement, we also amended and restated the Guaranty and Security Agreement, dated June 2, 2014, by and
between us and the other parties thereto, or the GSA, to, among other things, (i) provide that all of the notes will be secured by the liens securing the indebtedness under the
Deerfield Facility Agreement, and (ii) name Deerfield as the “Collateral Agent” under the GSA.

In connection with entering into the December 2019 Exchange Agreement, we also entered into an amendment, or the September 2019 Exchange Agreement Amendment, to
the September 2019 Exchange Agreement to, among other things, (i) amend and restate Annex I of the September 2019 Exchange Agreement to allow the Deerfield Lenders
to effect optional exchanges of the December 2019 Notes and the Deerfield Convertible Note under the terms of the September 2019 Exchange Agreement; (ii) amend the
common stock exchange price under the September 2019 Exchange Agreement to be a per share price equal to the greater of (x) $9.60, subject to adjustment to reflect stock
splits  and  similar  events,  or  (y)  the  average  of  the  volume-weighted  average  prices  of  our  common  stock  on  each  of  the  15  trading  days  immediately  preceding  such
exchange,  (iii)  provide  that  no  more  than  1,777,437  shares  of  our  common  stock  shall  be  issued  pursuant  to  optional  exchanges  under  the  September  2019  Exchange
Agreement (whether by common stock exchange or upon conversion of Series B-2 Shares (as defined in the September 2019 Exchange Agreement Amendment)), subject to
adjustment to reflect stock splits and similar events and (iv) eliminate limitations regarding the timing and aggregate amount of principal which may be exchanged under the
September 2019 Exchange Agreement.

In connection with entering into the September 2019 Exchange Agreement Amendment, we filed an amendment to the Certificate of Designation of Preferences, Rights and
Limitations  of  Series  B-2  Convertible  Preferred  Stock,  or  the  Series  B-2  Certificate  of  Designation  Amendment,  with  the  Secretary  of  State  of  the  State  Delaware.
The Series B-2 Certificate of Designation Amendment provides that each share of the Series B-Preferred Stock is convertible into shares of our common stock at a per share
price equal to the common stock exchange price under the September 2019 Exchange Agreement, which equals the greater of (i) $9.60 (subject to adjustment to reflect stock
splits  and  similar  events),  or  (ii)  the  average  of  the  volume-weighted  average  prices  of  our  common  stock  on  each  of  the  15  trading  days  immediately  preceding  such
exchange.

As of December 31, 2020, the Deerfield Lenders have converted $17.1 million of principal on the December 2019 Notes into all 1,777,437 shares of common stock issuable
under the Deerfield Optional Conversion Feature.

2021 Note Exchange Effected in January 2020

In January 2020, we entered into a January 2020 Exchange Agreement, or the January 2020 Exchange Agreement, with M. Kingdon Offshore Master Fund, LP, or Kingdon.
Under  the  January  2020  Exchange  Agreement,  we  issued  the  January  2020  Note  as  a  senior  secured  convertible  note  in  the  aggregate  principal  amount  of  $3,037,354  in
exchange for the cancellation of an aggregate of $3,037,354 principal amount and accrued interest of the 2021 Note then owned by Kingdon. Upon entering into the January
2020 Exchange Agreement, we agreed to pay Kingdon an interest payment of $37,354, which represents 50% of the accrued and unpaid interest, as of January 13, 2020, on
Kingdon’s 2021 Note. The remainder of such interest was included in the principal amount of the January 2020 Note.

The January 2020 Note was issued with substantially the same terms and conditions as the December 2019 Notes (as amended by the amendment described in more detail
below).

In connection with entering into the January 2020 Exchange Agreement, we entered into an Amendment to Facility Agreement and December 2019 Notes and Consent, or
the December 2019 Note Amendment, with the December 2019 Holders that, among other things, (i) amended the December 2019 Notes to (a) reduce the Conversion Price
(as defined in the December 2019 Notes) from $273.76 to $93.60 per share, (b) increased the Floor Price (as defined in the December 2019 Notes) from $6.08 to $9.328 per
share, and (ii) amended Deerfield Facility Agreement to (x) provide for Kingdon to join the Deerfield Facility Agreement as a Lender (as defined in the Deerfield Facility
Agreement) and (y) provide that the 2020 Note and shall constitute a “Senior Secured Convertible Note” (as defined in the Deerfield Facility Agreement) for purposes of the
Deerfield Facility Agreement and other Transaction Documents (as defined in the Deerfield Facility Agreement). As a result of the December 2019 Note Amendment, the
December 2019 Notes were convertible, by their terms, into an aggregate of 11,753,016 shares of our common stock, assuming a conversion date of January 13, 2020.

Debt Restructuring

In  December  2020,  we  entered  into  the  December  2020  Exchange  Agreement,  which  was  amended  on  December  24,  2020.  Pursuant  to  the  December  2020  Exchange
Agreement, and (a) we made the Debt Payment as a cash pre-payment of a portion of principal amount of the Senior Secured Notes and the Deerfield Note to the Deerfield
Lenders, DSC and Kingdon, or, collectively, the Holders,  in an aggregate amount equal to approximately $30.3 million,; and (b) issued 31,476.98412 shares of our Series B-2
Preferred Stock and warrants exercisable for 3,632,019 shares of our common stock, or the Exchange Warrants, in exchange for the cancellation of a portion of the principal
amount of the Senior Secured Notes and Deerfield Note owned by the Holders, with such transaction referred to as the Exchange. Immediately following the completion of the
Exchange and Debt Payment, the aggregate balance of principal and accrued interest remaining outstanding under the Facility Notes was approximately $7.6 million.

The December 2020 Exchange Agreement amended the Senior Secured Notes to provide that the failure of our common stock to remain listed on an eligible securities market
will not constitute a “Major Transaction” unless such failure occurs after March 31, 2023.

The December 2020 Exchange Agreement amended the Deerfield Facility Agreement in order to, among other things, (i) extend the maturity date of the Senior Secured Notes
and the Deerfield Note to March 31, 2023, (ii) provide for cash payments of interest on the Loans (as defined in the Deerfield Facility Agreement) for the periods following
July 1, 2021, and (iii) provide for specified prepayment terms on the Loans.

The December 2020 Exchange Agreement amended that certain Amended and Restated Investors’ Rights Agreement, dated as of February 19, 2015, or the IRA, by and among
us, Deerfield and the other parties signatory thereto in order to, among other things, add Deerfield Special Situations Fund, L.P. as a party thereto and to give effect to the
issuance of the Exchange Warrants and our registration obligations under the December 2020 Exchange Agreement (as described in more detail below).

The Exercise Warrants are subject to substantially the same terms and conditions as the Existing Warrants, with an exercise price equal to the exercise price per share of the
Existing Warrants and will provide that the Holders will be limited from exercising such Exchange Warrants if, as a result of such exercise, such holders (together with certain
affiliates and “group” members of such holders) would beneficially own more than 4.985% of the total number of shares of our common stock then issued and outstanding.

Pursuant to the terms of the December 2020 Exchange Agreement, we also filed a registration statement to register for resale under the Securities Act the shares of common
stock issuable upon conversion of the shares of Series B-2 Preferred Stock and exercise of the Exchange Warrants. 

In connection with the December 2020 Exchange Agreement, we filed an Amended and Restated Certificate of Designation of Preferences, Rights and Limitations of Series B-
2  Convertible  Preferred  Stock,  or  the  Amended  and  Restated  Series  B-2  Certificate  of  Designation,  with  the  Secretary  of  State  of  the  State  Delaware,  setting  forth  the
preferences, rights and limitations of the Series B-2 Preferred Stock.

The shares of Series B-2 Preferred Stock are convertible into an aggregate of 4,842,690 shares of our common stock. Each share of Series B-2 Preferred Stock will have an
aggregate stated value of $1,000 and will be convertible into shares of our common stock at a per share price equal to $6.4999 (subject to adjustment to reflect stock splits and
similar events).

The Series B-2 Preferred Stock will be convertible at any time on or after the PDUFA Date (as defined in the Amended and Restated Series B-2 Certificate of Designation) at
the option of the holders thereof; provided that the holders thereof will be prohibited from converting shares of Series B-2 Preferred Stock into shares our common stock if, as a
result of such conversion, such holders (together with certain affiliates and “group” members of such holders) would beneficially own more than 4.985% of the total number of
shares of our common stock then issued and outstanding. The Series B-2 Preferred Stock will not be redeemable. In the event of our liquidation, dissolution or winding up or
our change in control, the holders of Series B-2 Preferred Stock will receive, prior to any distribution or payment on our common stock, an amount equal to the greater of
(i) $1,000 per share (in the case of a change in control, transaction consideration with such value), or (ii) the amount (in the case of a change in control, in the form of the
transaction consideration) per share each such holder would have been entitled to receive if every share of Series B-2 Preferred Stock had been converted into common stock
immediately prior to such event, in each case, plus any declared but unpaid dividends thereon. With respect to rights upon liquidation, the Series B-2 Preferred Stock will rank
senior  to  our  common  stock,  on  parity  with  any  Parity  Securities  (as  defined  in  the  Amended  and  Restated  Series  B-2  Certificate  of  Designation)  and  junior  to  any  Senior
Securities (as defined in the Amended and Restated Series B-2 Certificate of Designation) and existing and future indebtedness. Except as otherwise required by law (or with
respect  to  approval  of  certain  actions  involving  our  organizational  documents  that  adversely  affect  the  holders  of  Series  B-2  Preferred  Stock  and  other  specified  matters
regarding the rights, preferences and privileges of the Series B-2 Preferred Stock), the Series B-2 Preferred Stock will not have voting rights. The Series B-2 Preferred Stock
will not be subject to any price-based anti-dilution protections and will not provide for any accruing dividends, but will provide that holders of Series B-2 Preferred Stock will
participate in any dividends on our common stock on an as-converted basis (without giving effect to the limitation on conversion described above). The Amended and Restated
Series B-2 Certificate of Designation also provides for partial liquidated damages in the event that we fail to timely convert shares of Series B-2 Preferred Stock into common
stock in accordance with the Amended and Restated Series B-2 Certificate of Designation.

December 2020 Exchange Agreement Amendment

On  January  12,  2021,  in  connection  with  the  transactions  contemplated  by  the  December  2020  Exchange  Agreement,  we  entered  into  an  Amendment  to  Senior  Secured
Convertible Notes and Amendment to Warrant, or the January 2021 Amendment, with the Deerfield Holders. The January 2021 Amendment modifies certain specified terms of
(i) the Facility Notes and (ii) the Deerfield Warrant to, among other things, exclude the transactions contemplated by the December 2020 Exchange Agreement and issuance of
securities pursuant to the Underwriting Agreement from the anti-dilution provisions of the Facility Notes and the Deerfield Warrant.

Series B-2 Preferred Stock

On January 11, 2021, as a condition to closing of the transactions contemplated by the December 2020 Exchange Agreement, we filed an Amended and Restated Certificate of
Designation of Preferences, Rights and Limitations of Series B-2 Convertible Preferred Stock, or the Series B-2 Certificate of Designation, with the Secretary of State of the
State Delaware, setting forth the preferences, rights and limitations of the Series B-2 Preferred Stock.

Payoff of Facility Agreement Notes and Termination of Facility Agreement

On  February  8,  2021,  we  entered  into  a  payoff  letter  with  the  Facility  Agreement  Note  Holders,  pursuant  to  which  we  agreed  to  pay  off  and  thereby  terminate  the  Facility
Agreement.

Pursuant  to  the  payoff  letter,  we  paid  a  total  of  $8.0  million  to  the  Facility  Agreement  Note  Holders,  representing  the  principal  balance,  accrued  interest  outstanding  and  a
prepayment fee in repayment of our outstanding obligations under the Facility Agreement.

Pursuant to the payoff letter, all outstanding indebtedness and obligations of us owing to the Facility Agreement Note Holders under the Facility Agreement have been paid in
full.  The  Facility  Agreement  and  the  notes  thereunder,  as  well  as  the  security  interests  in  the  assets  of  us  securing  the  Facility Agreement  and  note  obligations,  have  been
terminated. The Facility Agreement Note Holders will retain the warrants previously issued to them.

research and development programs, partially offset by revenue received under the KP415 License Agreement, and $5.1 million in changes in working capital; partially offset
by  $5.9  million  in  adjustments  for  non-cash  items.  The  adjustments  for  non-cash  items  primarily  consisted  of  stock-based  compensation  expense  of  $4.4  million,  non-cash
interest expense of $1.4 million, amortization of debt issuance costs and debt discount of $1.7 million and $0.4 million related to depreciation, amortization and other items;
partially offset by non-cash income related to the change in the fair value of our derivative and warrant liabilities of $2.0 million. The changes in working capital consisted of
$1.7 million related to a change in accounts and other receivables, $3.8 million related to a change in accounts payable and accrued expenses, $1.5 million related to operating
lease right-of-use assets and $0.8 million related to a change in other liabilities; partially offset by $0.5 million related to a change in prepaid expenses and other assets and
$2.2 million related to operating lease liabilities.

Investing Activities

For the year ended December 31, 2020, net cash used in investing activities was $33,000, which was attributable to purchases of property and equipment.

For the year ended December 31, 2019, net cash provided by investing activities was $3.2 million, which was primarily attributable to maturities of marketable securities of
$3.3 million, partially offset by purchases of property and equipment of $0.1 million.

Financing Activities

For the year ended December 31, 2020, net cash provided by financing activities was $2.7 million, which was primarily attributable to proceeds from sales of our common
stock under the 2020 ELOC of $2.3 million and proceeds from the PPP loan of $0.8 million, partially offset by repayment of principal on finance lease liabilities of $0.2 million
and payment of debt issuance and deferred offerings costs of $0.1 million.

For the year ended December 31, 2019, net cash provided by financing activities was $4.9 million, which was primarily attributable to proceeds from sales of our common
stock  under  the  2019  ELOC  of  $5.4  million;  partially  offset  by  repayment  of  principal  on  finance  lease  liabilities  of  $0.2  million  and  payment  of  debt  issuance  costs  of
$0.3 million.

Future Funding Requirements

Based  on  our  current  operating  forecast,  we  believe  that  the  proceeds  from  the  Public  Offering  and  inducement  warrant  transactions,  together  with  our  existing  cash
resources and after giving effect to the Deerfield Debt Payment and the Exchange, will be sufficient to fund our operations at least through Q1 2024. This estimate does not
include our projected revenue, a portion of which is based royalties from commercial sales and upon the achievement of milestones in the KP415 License Agreement and the
APADAZ License Agreement. Certain of the milestones are associated with regulatory matters that are outside our control.

Potential near-term sources of additional funding include:

  ● any revenues generated under either the KP415 License Agreement or the APADAZ License Agreement;

  ● any consulting services revenue or short-term milestone payments generated under the KP415 License Agreement;

  ● any consulting services revenue or short-term milestone payments generated under the Corium Consulting Agreement; and

  ● any consulting services revenue generated under other potential consulting arrangements.

We cannot guarantee that we will be able to generate sufficient proceeds from any of these potential sources to fund our operating expenses.

To  date,  we  have  generated  revenue  from  the  non-refundable  upfront  payment,  regulatory  milestone  payment,  reimbursements  of  out-of-pocket  third-party  research  and
development  costs  and  consulting  services  under  the  KP415  License  Agreement,  consulting  services,  and  associated  out-of-pocket  third-party  costs,  under  the  Corium
Consulting Agreement and consulting services under other consulting arrangements. We expect that our only sources of revenues will be through payments arising from the
KP415  License  Agreement,  the  APADAZ  License  Agreement,  the  Corium  Consulting  Agreement,  or  through  other  potential  consulting  arrangements  and  any  other  future
arrangements  related  to  one  of  our  product  candidates. While  we  have  entered  into  the  APADAZ  License  Agreement  to  commercialize  APADAZ  in  the  United  States,  and
entered into the KP415 License Agreement to develop, manufacture and commercialize AZSTARYS and KP484, we cannot guarantee that this, or any strategy we adopt in the
future, will be successful. For instance, we received a milestone payment of $5.0 million under the KP415 License Agreement due to the FDA’s acceptance of the AZSTARYS
NDA, and we have earned a regulatory milestone payment for the approval of the AZSTARYS NDA, but we cannot guarantee that we will earn any additional milestone or
royalty payments under this agreement in the future. We also expect to continue to incur additional costs associated with operating as a public company. If we are unable to
generate revenue in the short term under our license agreements, we will need substantial additional funding in order to continue our operations.

In  March  2020,  the  World  Health  Organization  declared  the  outbreak  of  COVID-19,  a  novel  strain  of  Coronavirus,  a  global  pandemic.  This  outbreak  is  causing  major
disruptions to businesses and markets worldwide as the virus spreads. We cannot predict what the long-term effects of this pandemic and the resulting economic disruptions
may have on our liquidity and results of operations. The extent of the effect of the COVID-19 pandemic on our liquidity and results of operations will depend on a number
future developments, including the duration, spread and intensity of the pandemic, and governmental, regulatory and private sector responses, all of which are uncertain and
difficult to predict. The COVID-19 pandemic may make it more difficult for us to enroll patients in any future clinical trials or cause delays in the regulatory approval of our
product  candidates,  including  causing  potential  delay  of  the  FDA’s  review  of  our  AZSTARYS  NDA.  A  portion  of  our  projected  revenue  is  based  upon  the  achievement  of
milestones in the KP415 License Agreement associated with regulatory matters that may be impacted by the COVID-19 pandemic. As a result, we cannot predict what, if any,
impact  that  the  COVID-19  pandemic  may  have  on  our  ability  to  achieve  these  milestones.  The  economic  uncertainty  surrounding  the  COVID-19  pandemic  may  also
dramatically reduce our ability to secure debt or equity financing necessary to support our operations. We are unable to currently estimate the financial effect of the pandemic. If
the pandemic continues to be a severe worldwide crisis, it could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

We have based our estimates of our cash needs and cash runway on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we
currently  expect  and  we  cannot  guarantee  that  we  will  be  able  to  generate  sufficient  proceeds  from  the  KP415  License  Agreement,  the  APADAZ  License  Agreement,  the
Corium  Consulting  Agreement,  and  other  potential  consulting  arrangements  or  other  funding  transactions  to  fund  our  operating  expenses.  To  meet  any  additional  cash
requirements,  we  may  seek  to  sell  additional  equity  or  convertible  securities  that  may  result  in  dilution  to  our  stockholders,  issue  additional  debt  or  seek  other  third-party
funding,  including  potential  strategic  transactions,  such  as  licensing  or  collaboration  arrangements.  Because  of  the  numerous  risks  and  uncertainties  associated  with  the
development  and  commercialization  of  product  candidates  and  products,  we  are  unable  to  estimate  the  amounts  of  increased  capital  outlays  and  operating  expenditures
necessary to complete the commercialization and development of our partnered product or product candidates, should they obtain regulatory approval.

Off-Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any off-balance sheet arrangements as defined under SEC rules.

Critical Accounting Policies and Significant Judgements and Estimates

This management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with
accounting principles generally accepted in the United States. The preparation of our financial statements requires us to make estimates and assumptions that affect the reported
amounts  of  assets  and  liabilities  and  the  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  our  financial  statements,  as  well  as  the  reported  revenues  and
expenses during the reported periods. We evaluate these estimates and judgements on an ongoing basis. We base our estimates on historical experience and on various other
factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgements about the carrying value of assets and liabilities that
are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note B to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K, we
believe  that  the  following  accounting  policies  are  critical  to  the  process  of  making  significant  judgments  and  estimates  in  the  preparation  of  our  financial  statements  and
understanding and evaluating our reported financial results.

Accrued Expenses

We enter into contractual agreements with third-party vendors who provide research and development, manufacturing, and other services in the ordinary course of business.
Some  of  these  contracts  are  subject  to  milestone-based  invoicing  and  services  are  completed  over  an  extended  period  of  time.  We  record  liabilities  under  these  contractual
commitments when an obligation has been incurred. This accrual process involves reviewing open contracts and purchase orders, communicating with our applicable personnel
to identify services that have been performed and estimating the level of service performed and the associated cost when we have not yet been invoiced or otherwise notified of
actual cost. The majority of our service providers invoice us monthly in arrears for services performed. We make estimates of our accrued expenses as of each balance sheet
date based on the facts and circumstances known to us. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary.
Examples of estimated accrued expenses include:

  ● fees paid to CROs in connection with preclinical and toxicology studies and clinical trials;

  ● fees paid to investigative sites in connection with clinical trials;

  ● fees paid to contract manufacturers in connection with the production of our raw materials, drug substance and product candidates; and

  ● professional fees.

We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs
that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven
payment  flows.  Payments  under  some  of  these  contracts  depend  on  factors  such  as  the  successful  enrollment  of  patients  and  the  completion  of  clinical  trial  milestones.  In
accruing service fees, we estimate the time period over which services will be performed and the level of effort expended in each period. If the actual timing of the performance
of services or the level of effort varies from our estimate, we will adjust the accrual accordingly. If we do not identify costs that we have begun to incur or if we underestimate
or overestimate the level of these costs, our actual expenses could differ from our estimates.

Stock-Based Compensation

We record the fair value of stock options issued as of the grant date as compensation expense. We recognize compensation expense over the requisite service period, which is
equal to the vesting period. Stock-based compensation expense has been reported in our statements of operations as follows (in thousands):

Determination of the Fair Value of Stock-Based Compensation Grants

We calculate the fair value of stock-based compensation arrangements using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the use
of subjective assumptions, including the expected volatility of our common stock, the assumed dividend yield, the expected term of our stock options, the risk-free interest rate
for a period that approximates the expected term of our stock options and the fair value of the underlying common stock on the date of grant. In applying these assumptions, we
considered the following factors:

  ● historically we have not had sufficient experience to estimate the volatility of our common stock. As such, we calculated the expected volatility based on reported data
for selected similar publicly traded companies for which the historical information is available, or peer volatility, and blended it with our historical volatility, or leverage-
adjusted peer volatility. For the purpose of identifying peer companies, we consider characteristics such as industry, length of trading history, similar vesting terms and
in-the-money option status. We utilized this leverage-adjusted peer volatility for grants prior to the initial public offering, as well as grants within the two-year period
immediately following the initial public offering. For grants after the second anniversary of the initial public offering we utilized our historical volatility to determine the
expected volatility;

  ● the assumed dividend yield is based on our expectation of not paying dividends for the foreseeable future;

  ● we determine the average expected life of “plain vanilla” stock options based on the simplified method in accordance with SEC Staff Accounting Bulletin Nos. 107 and
110,  as  our  common  stock  to  date  has  been  publicly  traded  for  a  limited  amount  of  time.  We  expect  to  use  the  simplified  method  until  we  have  sufficient
historical  exercise  data  to  provide  a  reasonable  basis  upon  which  to  estimate  expected  term.  For  options  that  are  not  considered  “plain  vanilla,”  such  as  those  with
exercise prices in excess of the fair market value of the underlying stock, we use an expected life equal to the contractual term of the option;

  ● we determine the risk-free interest rate by reference to implied yields available from U.S. Treasury securities with a remaining term equal to the expected life assumed at

the date of grant; and

  ● we estimate forfeitures based on our historical analysis of actual stock option forfeitures.

We account for stock-based compensation arrangements with directors and consultants that contain only service conditions for vesting using a fair value approach. The grant
date  fair  value  of  these  options  is  measured  using  the  Black-Scholes  option  pricing  model  reflecting  the  same  assumptions  as  applied  to  employee  options  in  each  of  the
reported periods, other than the expected life, which is assumed to be the remaining contractual life of the option.

The following summarizes the assumptions used for estimating the fair value of stock options granted to employees for the periods indicated:

Fair Value of Financial Instruments

We  have  a  common  stock  warrant  issued  to  Deerfield,  put  options  embedded  within  those  Deerfield  warrants,  and  common  stock  warrants  issued  to  KVK  that  meet  the
definition of derivative financial instruments and are accounted for as derivatives. The fair value of the common stock warrant issued to Deerfield, and put options embedded
within the Deerfield Warrants are based on Monte Carlo simulations, while the common stock warrant issued to KVK is valued using a probability-weighted Black-Scholes
option pricing model. These derivatives are fair valued at each reporting period.

The derivative liability for the Deerfield common stock warrant was $230,000 and $77,000 at December 31, 2020 and 2019, respectively. The derivative liability for the put
options embedded within the Deerfield common stock warrant was $25,000 and $19,000 at December 31, 2020 and 2019, respectively. The derivative liability for the KVK
common stock warrant was $49,000 and $24,000 at December 31, 2020 and 2019, respectively. A 10% increase in the enterprise value would result in an increase of $29,000 in
the estimated fair value of the Deerfield common stock warrant, an increase of $8,000 in the estimated fair value of the put options embedded within the Deerfield common
stock warrant and an increase of $8,000 in the estimated fair value of the KVK common stock warrant at December 31, 2020. Upon exercise of the warrants, we will adjust the
associated  derivative  liability  to  fair  value  with  any  changes  recorded  in  other  (expense)  income.  At  such  time,  such  derivative  liability  will  also  be  reclassified  to
additional paid-in capital, and no further revaluations will be necessary.

Utilization of Net Operating Loss Carryforwards and Research and Development Credits

As of December 31, 2020, we had federal net operating loss, or NOL, carryforwards of approximately $226.0 million, due to prior period losses, $138.1 million of which, if not
utilized, will begin to expire in 2027 and $87.8 million with no expiration. We also had research and development credit carryforwards of $3.8 million with expiration dates
ranging from 2027 to 2037 and $2.6 million with no expiration.

In accordance with Section 382 of the Code, a change in equity ownership of greater than 50% within a three-year period results in an annual limitation on a company’s ability
to  utilize  its  NOL  carryforwards  created  during  the  tax  periods  prior  to  the  change  in  ownership.  We  performed  a  Section  382  ownership  change  analysis  in  2017  and
determined that we experienced an ownership change in 2010, which resulted in a portion of our net operating loss carryforwards being subject to an annual limitation under
Section 382 through 2012. No other ownership changes or limitations on our historical net operating loss carryforwards were noted through the year ended December 31, 2017.
In  addition,  we  may  experience  ownership  changes  in  the  future  as  a  result  of  subsequent  shifts  in  our  stock  ownership,  including  as  a  result  of  the  conversion  of  our
outstanding convertible debt or as a result of future changes in our stock ownership. If we determine that an ownership change has occurred and our ability to use our historical
net operating loss carryforwards is materially limited, it would harm our future operating results by increasing our future tax obligations.

Recent Accounting Pronouncements

In  April  2012,  President  Obama  signed  the  JOBS  Act  into  law.  The  JOBS  Act  contains  provisions  that,  among  other  things,  reduce  certain  reporting  requirements  for  an
emerging growth company. As an emerging growth company, we could have elected to adopt new or revised accounting standards when they become effective for non-public
companies,  which  typically  is  later  than  public  companies  must  adopt  the  standards.  We  have  irrevocably  elected  not  to  take  advantage  of  the  extended  transition  period
afforded by the JOBS Act and, as a result, will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-
emerging growth companies.

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments—Credit  Losses  (Topic  326)—Measurement  of  Credit  Losses  on  Financial  Instruments  (“ASU  2016-
13”),  which  replaces  the  incurred  loss  impairment  methodology  with  a  methodology  that  reflects  expected  credit  losses  and  requires  consideration  of  a  broader  range  of
reasonable  and  supportable  information  to  inform  credit  loss  estimates.  This  update  applies  to  all  entities  holding  financial  assets  and  net  investment  in  leases  that  are  not
accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures,
reinsurance  receivables,  and  any  other  financial  assets  not  excluded  from  the  scope  that  have  the  contractual  right  to  receive  cash.  This  guidance  is  effective  for  financial
statements  issued  for  fiscal  years  beginning  after  December  15,  2019,  and  interim  periods  within  those  fiscal  years.  The  adoption  of ASU  2016-13  did  not  have  a  material
impact on our financial statements and disclosures.

In  August  2018,  the  FASB  issued  ASU  2018-13,  Fair  Value  Measurement  (Topic  820)—Disclosure  Framework—Changes  to  the  Disclosure  Requirements  for  Fair  Value
Measurement (“ASU 2018-13”), which modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, based on the concepts in the
FASB  Concepts  Statement,  Conceptual  Framework  for  Financial  Reporting—Chapter  8:  Notes  to  Financial  Statements,  which  the  FASB  finalized  on  August  28,  2018,
including the consideration of costs and benefits. This update applies to all entities that are required, under existing GAAP, to make disclosures about recurring or nonrecurring
fair value measurements. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2019, and interim periods within those fiscal
years.  The  amendments  on  changes  in  unrealized  gains  and  losses,  the  range  and  weighted  average  of  significant  unobservable  inputs  used  to  develop  Level  3  fair  value
measurements,  and  the  narrative  description  of  measurement  uncertainty  should  be  applied  prospectively  for  only  the  most  recent  interim  or  annual  period  presented  in  the
initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The adoption of ASU 2018-13 did not
have a material impact on our financial statements and disclosures.

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own
Equity (Subtopic 815-40); Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which addresses issues identified as a result of
the complexities associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. This update addresses, among other things,
the number of accounting models for convertible debt instruments and convertible preferred stock, targeted improvements to the disclosures for convertible instruments
and earnings-per-share (“EPS”) guidance and amendments to the guidance for the derivatives scope exception for contracts in an entity’s own equity, as well as the related EPS
guidance. This update applies to all entities that issue convertible instruments and/or contracts in an entity’s own equity. This guidance is effective for financial statements
issued for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning
after December 15, 2020, including interim periods within those fiscal years. FASB specified that an entity should adopt the guidance as of the beginning of its annual fiscal
year. We are currently evaluating the impact the adoption of ASU 2020-06 could have on our financial statements and disclosures.

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act that are 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 recorded, processed, summarized and reported, within the time periods specified in
the SEC's rules and forms. 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.

Our management, with the participation of our chief executive officer and our chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of
December 31, 2020. Based on the evaluation of our disclosure controls and procedures as of December 31, 2020, our chief executive officer and our chief financial officer
concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Controls over Financial Reporting

Internal controls over financial reporting refers to the process designed by, or under the supervision of, our chief executive officer and chief financial officer, and effected by our
board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that: (1) pertain to the maintenance of records that
in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to
permit  preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  our  receipts  and  expenditures  are  being  made  only  in
accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition,
use or disposition of the company's assets that could have a material effect on the financial statements.

Management is responsible for establishing and maintaining adequate internal controls over our financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(e)
under the Exchange Act. Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an
evaluation  of  the  effectiveness  of  our  internal  controls  over  financial  reporting.  Management  has  used  the  framework  set  forth  in  the  report  entitled  "Internal  Control  –
Integrated Framework (2013)" published by the Committee of Sponsoring Organizations of the Treadway Commission to evaluate the effectiveness of our internal controls
over financial reporting. Based on its evaluation, management has concluded that our internal controls over financial reporting were effective as of December 31, 2020, the end
of our most recent fiscal year.

Our independent registered public accounting firm has not performed an evaluation of our internal controls over financial reporting during any period in accordance with the
provisions of the Sarbanes-Oxley Act. For as long as we remain a smaller reporting company, we intend to take advantage of the exemption permitting us not to comply with
the requirement that our independent registered public accounting firm provide an attestation on the effectiveness of our internal controls over financial reporting.

Changes in Internal Controls over Financial Reporting

In  connection  with  the  evaluation  required  by  Rules  13a-15(d)  and  15d-15(d)  of  the  Exchange  Act  that  occurred  during  the  most  recent  fiscal  quarter,  we  noted  a  material
change  in  our  internal  controls  over  financial  reporting  where  we  entered  into  an  agreement  with  a  third-party  financial  accounting  advisory  firm  to  provide  professional
services on an as-needed basis. These services could range from technical accounting assistance to staff loan opportunities dependent upon our needs.

Inherent Limitations on Effectiveness of Controls

Our management, including our chief executive officer and our chief financial officer, believes that our disclosure controls and procedures and internal controls over financial
reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. However, our management does not
expect that our disclosure controls and procedures or our internal controls over financial reporting will prevent all errors and all fraud. A control system, no matter how well
conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must
reflect  the  fact  that  there  are  resource  constraints,  and  the  benefits  of  controls  must  be  considered  relative  to  their  costs.  Because  of  the  inherent  limitations  in  all  control
systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the
realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the
individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon
certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future
conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of
the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  KemPharm, Inc. (the Company) as of December  31,  2020  and  2019,  the  related  statements  of  operations, changes  in
stockholders’ deficit and cash flows for the years then ended, and the related notes (collectively, the financial statements). In our opinion, the 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 the years then ended in
conformity with accounting principles generally accepted in the United States of America.

Basis of Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our
audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with
respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an
audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the
purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe
that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or  required  to  be
communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging,
subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are
not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

As  described  in  Note  B  to  the  financial  statements,  the  Company’s  revenues  are  derived  from  contracts  with  customers  that  may  include  multiple  performance  obligations,
consideration  constrained  by  regulatory  milestones  over  which  the  Company  may  have  little  or  no  control,  and  services  that  may  be  delivered  over  a  period  of  time. 
Management exercises significant judgement in determining revenue recognition for these customer agreements including:

  ● Determination of stand-alone selling prices (SSP) for each distinct performance obligation.

  ● Timing of when revenue is recognized for each distinct performance obligation.

  ● Estimation of constrained consideration to be included in the transaction price when determining the amount of revenue to recognize.

  ● Determining the time period over which to recognize revenue.

We identified the Company’s revenue recognition related to its collaboration and license contracts and other contracts as a critical audit matter because the identification of
accounting  performance  obligations,  determination  of  the  initial  transaction  price  and  estimation  of  SSP  for  each  performance  obligation  and  estimation  of  the  period  over
which to recognize revenue required significant audit effort and a high degree of auditor judgment and subjectivity to evaluate the evidence obtained.

Our procedures related to the Company’s revenue recognition for these customer agreements included the following, among others:

  ● Evaluated the Company’s significant accounting policies related to customer agreements in accordance with the applicable accounting standards.

  ● Obtained customer agreements and performed the following procedures, among others:

  ○ Obtained and read contract source documents, including master agreements, statements of work, and other documents that were part of the agreement.

  ○

Tested  management’s  identification  of  significant  terms  for  completeness,  including  the  identification  of  distinct  performance  obligations  and  constrained
consideration.

  ○ Tested management’s evaluation of the time period over which revenue should be recognized.

  ●

Evaluated management’s estimate of SSP related to products and services that are not sold separately for reasonableness and tested the completeness and accuracy of the
data used in determining the SSP.

Food  and  Drug  Administration  (the  "FDA")  approved  drugs  as  well  as  to  generate  prodrug  versions  of  existing  compounds  that  may  have  applications  for  new  disease
indications.  The  Company's  product  candidate  pipeline  is  focused  on  the  high  need  areas  of  attention  deficit  hyperactivity  disorder  ("ADHD")  and  stimulant  use  disorder
("SUD").  The  Company's  clinical  product  candidates  for  the  treatment  of  ADHD  include  AZSTARYS™  (formerly  referred  to  as  KP415)  and  KP484,  and  the  Company's
clinical product candidate for the treatment of SUD includes KP879. In addition, the Company has received FDA approval for APADAZ®, an immediate-release combination
product  containing  benzhydrocodone,  a  prodrug  of  hydrocodone  and  acetaminophen.  On  March  2,  2021,  the  Company  announced  that  the  FDA  approved  the  new  drug
application ("NDA") for AZSTARYS, a once-daily product for the treatment of ADHD in patients age six years and older.

Reverse Stock Split

On  December  23,  2020,  the  Company  completed  a  one-for-sixteen  reverse  stock  split  (the  “Reverse  Stock  Split”),  which  reduced  the  number  of  shares  of  the  Company’s
common stock that were issued and outstanding immediately prior to the effectiveness of the Reverse Stock Split. The number of shares of the Company’s authorized common
stock was not affected by the Reverse Stock Split and the par value of the Company’s common stock remained unchanged at $0.0001 per share. No fractional shares were
issued in connection with the Reverse Stock Split. Stockholders who otherwise held fractional shares of the Company’s common stock as a result of the Reverse Stock Split
received  a  cash  payment  in  lieu  of  such  fractional  shares.  Except  where  disclosed,  all  amounts  related  to  number  of  shares  and  per  share  amounts  have  been  retroactively
restated in these financial statements.

Liquidity

The  financial  statements  have  been  prepared  on  a  going  concern  basis  which  assumes  that  the  Company  will  be  able  to  realize  its  assets  and  discharge  its  liabilities  in  the
normal course of business for the foreseeable future. The Company has experienced recurring negative operating cash flows and has a stockholders' deficit, and its cash and
cash equivalents and restricted cash as of December 31, 2020 are not sufficient to fund the Company’s operating expenses and capital expenditure requirements for at least one
year  from  December  31,  2020.  However,  after  taking  into  account  the  underwritten  public  offering,  debt  restructuring  with  subsequent  payoff  and  warrant  inducement
transactions  discussed  in  Note  R  this  concern  has  been  alleviated  and  the  Company's  cash  and  cash  equivalents  as  of  the  filing  date  are  sufficient  to  fund  the  Company's
operating expenses and capital expenditure requirements for a least one year from the date these financial statements are issued.

Entry into 2019 ELOC Agreement

In February 2019, the Company entered into a purchase agreement for an equity line of credit (the “2019 ELOC Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln
Park”) which provided that, upon the terms and subject to the conditions and limitations set forth therein, the Company previously could sell to Lincoln Park up to $15.0 million
of shares of common stock from time to time over the 36-month term of the 2019 ELOC Agreement, and upon execution of the 2019 ELOC Agreement, the Company issued an
additional 7,512 shares of common stock to Lincoln Park as commitment shares in accordance with the closing conditions within the 2019 ELOC Agreement. Concurrently
with  entering  into  the  2019  ELOC  Agreement,  the  Company  also  entered  into  a  registration  rights  agreement  with  Lincoln  Park  (the  “2019  ELOC  Registration  Rights
Agreement”) pursuant to which the Company agreed to register the sale of the shares of common stock that have been and may be issued to Lincoln Park under the 2019 ELOC
Agreement  pursuant  to  the  Company’s  existing  shelf  registration  statement  on  Form  S-3  or  a  new  registration  statement.  The  2019  ELOC  Agreement  was  terminated  in
February  2020  in  connection  with  entering  into  the  2020  ELOC  Agreement  (discussed  below).  Prior  to  the  termination  of  the  2019  ELOC  Agreement,  the  Company  sold
212,579  shares  of  common  stock  to  Lincoln  Park  (exclusive  of  the  7,512  commitment  shares)  under  the  2019  ELOC  Agreement  for  gross  proceeds  of  approximately
$5.4 million.

Entry into 2020 ELOC Agreement

In February 2020, the Company entered into a purchase agreement for an equity line of credit (the “2020 ELOC Agreement”) with Lincoln Park which provides that, upon the
terms and subject to the conditions and limitations set forth therein, the Company may sell to Lincoln Park up to $4.0 million of shares of common stock from time to time over
the 12-month term of the 2020 ELOC Agreement, and upon execution of the 2020 ELOC Agreement the Company issued an additional 19,289 shares of common stock to
Lincoln Park as commitment shares in accordance with the closing conditions within the 2020 ELOC Agreement. Concurrently with entering into the 2020 ELOC Agreement,
the Company also entered into a registration rights agreement with Lincoln Park (the “2020 ELOC Registration Rights Agreement”) pursuant to which the Company agreed to
register the sale of the shares of common stock that have been and may be issued to Lincoln Park under the 2020 ELOC Agreement pursuant to the Company’s existing shelf
registration  statement  on  Form  S-3  or  a  new  registration  statement.  In  May  2020,  the  Company  reached  the  maximum  allowable  shares  to  be  issued  under  the  Current
Registration Statement of 579,260 shares (inclusive of the 19,289 commitment shares) as defined in Section 2(f)(i) of the 2020 ELOC Agreement and therefore cannot issue
additional shares under the 2020 ELOC Agreement. As of December 31, 2020, the Company has sold 559,971 shares of common stock to Lincoln Park (exclusive of the 19,289
commitment shares) under the 2020 ELOC Agreement for gross proceeds of approximately $2.3 million.

License Agreements

Entry into KP415 License Agreement

In  September  2019,  the  Company  entered  into  a  Collaboration  and  License  Agreement  (the  “KP415  License  Agreement”)  with  Commave  Therapeutics  SA,  an  affiliate  of
Gurnet Point Capital (“Commave”). Under the KP415 License Agreement, the Company granted to Commave an exclusive, worldwide license to develop, manufacture and
commercialize the Company’s product candidates containing serdexmethylphenidate (“SDX”) and d-methylphenidate (“d-MPH”), including AZSTARYS, KP484, and, at the
option of Commave, KP879, KP922 or any other product candidate developed by the Company containing SDX and developed to treat ADHD or any other central nervous
system  disorder  (the  “Additional  Product  Candidates”  and,  collectively  with  AZSTARYS  and  KP484,  the  “Licensed  Product  Candidates”).  Pursuant  to  the  KP415  License
Agreement, Commave (i) paid the Company an upfront payment of $10.0 million; (ii) agreed to pay milestone payments of up to $63.0 million upon the occurrence of specified
regulatory  milestones  related  to  AZSTARYS  and  KP484;  (iii)  agreed  to  pay  additional  payments  of  up  to  $420.0  million  upon  the  achievement  of  specified  U.S.  sales
milestones; and (iv) has agreed to pay the Company quarterly, tiered royalty payments ranging from a percentage in the high single digits to the mid-twenties of Net Sales (as
defined in the KP415 License Agreement) in the United States and a percentage in the low to mid-single digits of Net Sales in each country outside the United States, in each
case subject to specified reductions under certain conditions as described in the KP415 License Agreement. Commave is obligated to make such royalty payments on a product-
by-product basis until expiration of the Royalty Term (as defined in the KP415 License Agreement) for the applicable product.

In  May  2020,  the  FDA  accepted  the  Company’s  NDA  for  AZSTARYS.  Per  the  KP415  License  Agreement,  the  Company  received  a  regulatory  milestone  payment  of
$5.0 million following the FDA’s acceptance of the AZSTARYS NDA.

Commave  has  also  agreed  to  be  responsible  and  reimburse  the  Company  for  all  of  development,  commercialization  and  regulatory  expenses  for  the  Licensed  Product
Candidates, subject to certain limitations as set forth in the KP415 License Agreement.

The  KP415  License  Agreement  also  established  a  joint  steering  committee,  which  monitors  progress  of  the  development  of  both  AZSTARYS  and  KP484.  Subject  to  the
oversight of the joint steering committee, the Company otherwise retains all responsibility for the conduct of all regulatory activities required to obtain new drug application
approval of AZSTARYS and KP484; provided that Commave shall be the sponsor of any clinical trials conducted by the Company on behalf of Commave.

In  accordance  with  the  terms  of  the  Company’s  March  20,  2012  Termination  Agreement  with  Aquestive  Therapeutics  (formerly  known  as  MonoSol  Rx,  LLC),  Aquestive
Therapeutics has the right to receive an amount equal to 10% of any royalty or milestone payments made to the Company related to AZSTARYS, KP484 or KP879 under the
KP415 License Agreement.

Entry into APADAZ License Agreement

In October 2018, the Company entered into a Collaboration and License Agreement (the “APADAZ License Agreement”) with KVK Tech, Inc. (“KVK”) pursuant to which we
have granted an exclusive license to KVK to conduct regulatory activities for, manufacture and commercialize APADAZ in the United States.

Pursuant  to  the  APADAZ  License  Agreement,  KVK  agreed  to  pay  the  Company  certain  payments  and  cost  reimbursements  of  an  estimated  $3.4  million,  which  includes  a
payment of $2.0 million within 10 days of the achievement of a specified milestone related to the initial formulary adoption of APADAZ (the “Initial Adoption Milestone”). In
addition, KVK has agreed to make additional payments to the Company upon the achievement of specified sales milestones of up to $53.0 million in the aggregate. Further, the
Company and KVK will share the quarterly net profits of APADAZ by KVK in the United States at specified tiered percentages, ranging from the Company receiving 30% to
50% of net profits, based on the amount of net sales on a rolling four quarter basis. The Company is responsible for a portion of commercialization and regulatory expenses for
APADAZ until the Initial Adoption Milestone is achieved, after which KVK will be responsible for all expenses incurred in connection with commercialization and maintaining
regulatory approval in the United States.

The APADAZ License Agreement will terminate on the later of the date that all of the patent rights for APADAZ have expired in the United States or KVK’s cessation of
commercialization of APADAZ in the United States. KVK may terminate the APADAZ License Agreement upon 90 days written notice if a regulatory authority in the United
States orders KVK to stop sales of APADAZ due to a safety concern. In addition, after the third anniversary of the APADAZ License Agreement, KVK may terminate the
APADAZ License Agreement without cause upon 18 months prior written notice. The Company may terminate the APADAZ License Agreement if KVK stops conducting
regulatory activities for or commercializing APADAZ in the United States for a period of six months, subject to specified exceptions, or if KVK or its affiliates challenge the
validity, enforceability or scope of any licensed patent under the APADAZ License Agreement. Both parties may terminate the APADAZ License Agreement (i) upon a material
breach of the APADAZ License Agreement, subject to a 30-day cure period, (ii) if the other party encounters bankruptcy or insolvency or (iii) if the Initial Adoption Milestone
is not achieved. Upon termination, all licenses and other rights granted by the Company to KVK pursuant to the APADAZ License Agreement would revert to the Company.

The APADAZ License Agreement also established a joint steering committee, which monitors progress of the commercialization of APADAZ.

Consulting Arrangements

From time to time, the Company enters into consulting arrangements with third-parties to provide research and development, manufacturing and/or commercialization services.
Such arrangements may require the Company to deliver various rights, services, including research and development services, regulatory services and/or commercialization
services.  The  underlying  terms  of  these  arrangements  generally  provide  for  consideration  to  the  Company  in  the  form  of  consulting  fees  and  reimbursements  of  out-of-
pocket third-party research and development, regulatory and commercial costs.

Corium Consulting Agreement

In July 2020, the Company entered into a consultation services arrangement (the “Corium Consulting Agreement”) with Corium, Inc. (“Corium”) under which Corium engaged
the Company to guide the product development and regulatory activities for certain current and potential future products in Corium’s portfolio, as well as continue supporting
preparation  for  the  potential  commercial  launch  of  AZSTARYS  (together,  “Corium  Consulting  Services”).  Corium  is  a  portfolio  company  of  Gurnet  Point  Capital  and  is
responsible for leading all commercialization activities for AZSTARYS under the KP415 License Agreement, as discussed above.

Under the Corium Consulting Agreement, the Company is entitled to receive payments from Corium of up to $15.6 million, $13.6 million of which will be paid in quarterly
installments through March 31, 2022. The remaining $2.0 million is conditioned upon the achievement of a specified regulatory milestone related to Corium’s product portfolio.
Corium also agreed to be responsible for and reimburse the Company for all development, commercialization and regulatory expenses incurred as part of the performance of the
Corium Consulting Services.

Summary of Significant Accounting Policies

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  U.S.  GAAP  requires  the  Company  to  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  the
financial statements and accompanying notes. Actual results could differ from those estimates.

On  an  ongoing  basis,  the  Company  evaluates  its  estimates  and  assumptions,  including  those  related  to  revenue  recognition,  the  useful  lives  of  property  and  equipment,  the
recoverability of long-lived assets, the incremental borrowing rate for leases, and assumptions used for purposes of determining stock-based compensation, income taxes, and
the fair value of the derivative and warrant liability, among others. The Company bases its estimates on historical experience and on various other assumptions that it believes to
be reasonable, the results of which form the basis for making judgments about the carrying value of assets and liabilities.

Concentration of Credit Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash on deposit with multiple financial institutions, the balances
of which frequently exceed insured limits, and accounts receivable, which are concentrated amongst a limited number of customers.

Cash and Cash Equivalents

The Company considers any highly liquid investments with an original maturity of three months or less to be cash equivalents.

Property and Equipment

The Company records property and equipment at cost less accumulated depreciation and amortization. Costs of renewals and improvements that extend the useful lives of the
assets are capitalized. Maintenance and repairs are expensed as incurred. Depreciation is determined on a straight-line basis over the estimated useful lives of the assets, which
generally range from three to ten years. Leasehold improvements are amortized over the shorter of the useful life of the asset or the term of the related lease. Upon retirement or
disposition of assets, the costs and related accumulated depreciation and amortization are removed from the accounts with the resulting gains or losses, if any, reflected in the
statements of operations.

Debt Issuance Costs

Debt issuance costs incurred in connection with financing arrangements are recorded as a reduction of the related debt on the balance sheet and amortized over the life of the
respective financing arrangement using the effective interest method.

Offering Costs

Offering costs incurred in connection with capital offering arrangements are recorded as deferred offering costs in prepaid expenses and other currents assets on the balance
sheet. Once the offering arrangement closes the deferred offering costs are reclassified as a reduction of the related net proceeds of the offering in additional paid-in capital on
the  balance  sheet.  If  its  a  continuous  offering  the  deferred  offering  costs  are  amortized  over  the  life  of  the  respective  offering  arrangement  using  a  pro-rata  method  which
matches the costs to the funds raised from the offering. If the continuous offering arrangement terminates prior to all the deferred offering costs being recognized the deferred
offering costs are written off and expensed in general and administrative expense on the statement of operations.

Supply Arrangements

The  Company  enters  into  supply  arrangements  for  the  supply  of  components  of  its  product  and  product  candidates.  These  arrangements  also  may include  a  share  of  future
revenue if related product or product candidates reach commercialization. Costs under these supply arrangements, if any, are expensed as incurred (Note I).

Impairment of Long-Lived Assets

Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be
recoverable. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If the undiscounted cash
flows  are  insufficient  to  recover  the  carrying  values,  an  impairment  loss  is  recorded  for  the  difference  between  the  carrying  values  and  fair  values  of  the  asset.  No  such
impairment occurred for the years ended December 31, 2020 or 2019.

121

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement
date, based on the Company’s principal or, in absence of a principal, most advantageous market for the specific asset or liability.

The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities
measured  at  fair  value  on  a  non-recurring  basis,  in  periods  subsequent  to  their  initial  measurement.  The  hierarchy  requires  the  Company  to  use  observable  inputs  when
available, and to minimize the use of unobservable inputs, when determining fair value. The three tiers are defined as follows:

● Level 1—Observable inputs that reflect quoted market prices (unadjusted) for identical assets or liabilities in active markets; 

● Level 2—Observable inputs other than quoted prices in active markets that are observable either directly or indirectly in the marketplace for identical or similar assets

and liabilities; and

● Level 3—Unobservable inputs that are supported by little or no market data, which require the Company to develop its own assumptions.

Revenue Recognition

The Company commenced recognizing revenue in accordance with the provisions of ASC 606, Revenue from Contracts with Customers (“ASC 606”), starting January 1, 2018.
However, the Company had no revenue until the third quarter of 2019.

Arrangements with Multiple-Performance Obligations

From time to time, the Company enters into arrangements for research and development, manufacturing and/or commercialization services. Such arrangements may require the
Company  to  deliver  various  rights,  services,  including  intellectual  property  rights/licenses,  research  and  development  services,  and/or  commercialization  services.  The
underlying terms of these arrangements generally provide for consideration to the Company in the form of nonrefundable upfront license fees, development and commercial
performance milestone payments, royalty payments, consulting fees and/or profit sharing.

In arrangements involving more than one performance obligation, each required performance obligation is evaluated to determine whether it qualifies as a distinct performance
obligation based on whether (i) the customer can benefit from the good or service either on its own or together with other resources that are readily available and (ii) the good or
service is separately identifiable from other promises in the contract. The consideration under the arrangement is then allocated to each separate distinct performance obligation
based on its respective relative stand-alone selling price. The estimated selling price of each deliverable reflects the Company’s best estimate of what the selling price would be
if  the  deliverable  was  regularly  sold  by  the  Company  on  a  stand-alone  basis  or  using  an  adjusted  market  assessment  approach  if  selling  price  on  a  stand-alone  basis  is  not
available.

The  consideration  allocated  to  each  distinct  performance  obligation  is  recognized  as  revenue  when  control  of  the  related  goods  or  services  is  transferred.  Consideration
associated with at-risk substantive performance milestones is recognized as revenue when it is probable that a significant reversal of the cumulative revenue recognized will not
occur.  Should  there  be  royalties,  the  Company  utilizes  the  sales  and  usage-based  royalty  exception  in  arrangements  that  resulted  from  the  license  of  intellectual  property,
recognizing revenues generated from royalties or profit sharing as the underlying sales occur.

122

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Licensing Agreements

The Company enters into licensing agreements with licensees that fall under the scope of ASC 606.

The  terms  of  the  Company’s  licensing  agreements  typically  include  one  or  more  of  the  following:  (i)  upfront  fees;  (ii)  milestone  payments  related  to  the  achievement  of
development, regulatory, or commercial goals; and (iii) royalties on net sales of licensed products. Each of these payments may result in licensing revenues.

As part of the accounting for these agreements, the Company must develop estimates and assumptions that require judgment to determine the underlying stand-alone selling
price for each performance obligation which determines how the transaction price is allocated among the performance obligations. Generally, the estimation of the stand-alone
selling  price  may  include  such  estimates  as,  independent  evidence  of  market  price,  forecasted  revenues  or  costs,  development  timelines,  discount  rates,  and
probability of regulatory success. The Company evaluates each performance obligation to determine if they can be satisfied at a point in time or over time, and it measures the
services delivered to the licensee which are periodically reviewed based on the progress of the related program. The effect of any change made to an estimated input component
and, therefore revenue or expense recognized, would be recorded as a change in estimate. In addition, variable consideration (e.g., milestone payments) must be evaluated to
determine if it is constrained and, therefore, excluded from the transaction price.

Up-front  Fees:  If  a  license  to  the  Company’s  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the  arrangement,  the
Company recognizes revenues from the transaction price allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from
the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether
the combined performance obligation is satisfied over time or at a point in time.

Milestone  Payments: At  the  inception  of  each  arrangement  that  includes  milestone  payments  (variable  consideration),  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 transaction price. Milestone payments that are not within the Company’s or the licensee’s
control, such as non-operational developmental and regulatory approvals, are generally not considered probable of being achieved until those approvals are received. At the end
of each reporting period, the Company re-evaluates the probability of achievement of milestones that are within its or the licensee’s control, such as operational developmental
milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis,
which would affect collaboration revenues and earnings in the period of adjustment. Revisions to the Company’s estimate of the transaction price may also result in negative
licensing revenues and earnings in the period of adjustment.

KP415 License Agreement

In  September  2019,  the  Company  entered  into  the  KP415  License  Agreement  with  Commave  under  which  the  Company  granted  to  Commave  an  exclusive,
worldwide  license  to  develop,  manufacture  and  commercialize  the  Company’s  product  candidates  containing  SDX  and  d-MPH,  including  AZSTARYS,  KP484,  and,  at  the
option of Commave, KP879, KP922 and/or any other product candidate developed by the Company containing SDX and developed to treat ADHD or any other central nervous
system disorder. The license granted to Commave is distinct from other performance obligations as Commave can benefit from the license either on its own or together with
other resources that are readily available and the license is separately identifiable from other promises in the KP415 License Agreement.

In exchange for the exclusive, worldwide license, discussed above, Commave paid the Company a non-refundable upfront payment of $10.0 million. The Company is also
entitled to additional payments from Commave of up to $63.0 million, conditioned upon the achievement of specified regulatory milestones related to AZSTARYS and KP484.
In  May  2020,  the  FDA  accepted  the  Company’s  NDA  for  AZSTARYS.  Per  the  KP415  License  Agreement,  the  Company  received  a  regulatory  milestone  payment  of
$5.0  million  following  the  FDA’s  acceptance  of  the  AZSTARYS  NDA.  In  addition,  the  Company  is  entitled  to  payments  from  Commave  of  up  to  $420.0  million  in  the
aggregate, conditioned upon the achievement of certain U.S. sales milestones, which are dependent upon, among other things, the timing of approval for a new drug application
for AZSTARYS and its final approved label, if any. Further, Commave will pay the Company quarterly, tiered royalty payments ranging from a percentage in the high single
digits to mid-twenties of Net Sales (as defined in the KP415 License Agreement) in the U.S. and a percentage in the low to mid-single digits of Net Sales in each country
outside of the U.S., in each case subject to specified reductions under certain conditions as described in the KP415 License Agreement

Commave also agreed to be responsible for and reimburse the Company for all of development, commercialization and regulatory expenses incurred on the licensed products,
subject to certain limitations as set forth in the KP415 License Agreement. As part of this agreement the Company is obligated to perform consulting services on behalf of
Commave related to the licensed products. For these consulting services, Commave has agreed to pay the Company a set rate per hour on any consulting services performed on
behalf of Commave for the benefit of the licensed products.

The KP415 License Agreement is within the scope of ASC 606, as the transaction represents a contract with a customer where the participants function in a customer / vendor
relationship  and  are  not  exposed  equally  to  the  risks  and  rewards  of  the  activities  contemplated  under  the  KP415  License  Agreement.  Using  the  concepts  of  ASC  606,  the
Company identified the grant of the exclusive, worldwide license and the performance of consulting services, which includes the reimbursement of out-of-pocket third-party
research  and  development  costs,  as  its  only  two  performance  obligations  at  inception.  The  Company  further  determined  that  the  transaction  price,  at  inception,  under  the
agreement  was  $10.0  million  upfront  payment  plus  the  fair  value  of  the  Development  Costs  (as  defined  in  the  KP415  License  Agreement)  which  was  allocated  among  the
performance obligations based on their respective related stand-alone selling price.

The consideration allocated to the grant of the exclusive, worldwide license was $10.0 million, which reflects the standalone selling price. The Company utilized the adjusted
market  assessment  approach  to  determine  this  standalone  selling  price  which  included  analyzing  prospective  offers  received  from  various  entities  throughout  our  licensing
negotiation process as well as the consideration paid to other competitors in the market for a similar type transaction. The Company determined that the intellectual property
licensed under the KP415 License Agreement represented functional intellectual property and it has significant standalone functionality and therefore should be recognized at a
point  in  time  as  opposed  to  over  time.  The  revenue  related  to  the  grant  of  the  exclusive,  worldwide  license  was  recognized  at  a  point  in  time  at  the  inception  of  the
KP415 License Agreement.

The consideration allocated to the performance of consulting services, which includes the reimbursement of out-of-pocket third-party research and development costs, was the
fair value of the Development Costs (as defined in the KP415 License Agreement), which reflects the standalone selling price. The Company utilized a blended approach which
took into consideration the adjusted market assessment approach and the expected cost plus a margin approach to determine this standalone selling price. This blended approach
utilized the adjusted market approach and expected cost plus margin approach to value the performance of consulting services which included analyzing hourly rates of vendors
in the a market who perform similar services to those of the Company to develop a range and then analyzing the average cost per hour of our internal resources and applying a
margin  which  placed  the  value  in  the  median  of  the  previously  identified  range.  For  the  reimbursement  of  out-of-pocket  third-party  research  and  development  costs  the
Company utilized the expected cost plus a margin approach, which included estimating the actual out-of-pocket cost the Company expects to pay to third-parties for research
and  development  costs  and  applying  a  margin,  if  necessary.  The  Company  determined  that  no  margin  was  necessary  of  these  out-of-pocket  third-party  research  and
development costs as these are purely pass-through costs and the margin for managing these third-party activities is included within the value of the performance of consulting
services.  The  Company  determined  that  the  performance  of  consulting  services,  including  reimbursement  of  out-of-pocket  third-party  research  and  development  costs,  is  a
performance obligation that is satisfied over time as the services are performed and the reimbursable costs are paid. As such, the revenue related to the performance obligation
will  be  recognized  as  the  consulting  services  are  performed  and  the  services  associated  with  the  reimbursable  out-of-pocket  third-party  research  and  development  costs  are
incurred and paid by the Company, in accordance with the practical expedient allowed under ASC 606 regarding an entity’s right to consideration from a customer in an amount
that corresponds directly to the value to the customer of the entity’s performance completed to date. As discussed above, the combination of the standalone selling price of these
consulting  services  and  certain  out-of-pocket  third-party  research  and  development  costs  for  AZSTARYS  was  the  fair  value  of  the  Development  Costs  at  inception.  These
Development  Costs  effectively  created  a  cap  on  certain  consulting  services  and  out-of-pocket  third-party  research  and  development  costs  identified  in  the  initial  product
development plan for AZSTARYS which was anticipated at the inception date of the KP415 License Agreement. As of December 31, 2020, the Company has recognized all of
the consulting services and out-of-pocket third-party research and development costs under this cap.

Under  the  KP415  License  Agreement,  Commave  was  granted  an  exclusive  right  to  first  negotiation  whereby  upon  completion  of  a  Phase  1  proof-of-concept  study,  the
Company and Commave may negotiate the economics terms under which that certain Additional Product may be included as a Product option to include Additional Products as
Product(s) (both as defined in the KP415 License Agreement) under the KP415 License Agreement (the “Additional Product Option”). In addition to the Additional Product
Option, Commave was also granted a right of first refusal (“ROFR”) to acquire, license and/or commercialize any of the Additional Product Candidates should they choose not
to  exercise  the  Additional  Product  Option.  Should  Commave  choose  to  exercise  the  Additional  Product  Option  on  any  Additional  Product  Candidates,  Commave  and  the
Company  shall  negotiate  in  good  faith  regarding  the  economic  terms  of  such  Additional  Product.  Further,  should  Commave  exercise  the  ROFR  on  any  Additional  Product
Candidate, the economic terms of the agreement shall be the same as those offered to the third-party. Under ASC 606 an option to acquire additional goods or services gives rise
to a performance obligation if the option provides a material right to the customer. The Company concluded that the above described Additional Product Option and ROFR do
not constitute material rights to the customer as Commave would acquire the goods or services at a to be negotiated price, which the Company expects to approximate fair value
and therefore Commave would not receive a material discount on these goods or services compared to market rates.

The Company is entitled to additional payments from Commave conditioned upon the achievement of specified regulatory milestones related to AZSTARYS and KP484 and
the achievement of certain U.S. sales milestones, which are dependent upon, among other things, the timing of approval for a new drug application for AZSTARYS and its final
approved label, if any. Further, Commave will pay the Company quarterly, tiered royalty payments ranging from a percentage in the high single digits to mid-twenties of Net
Sales (as defined in the KP415 License Agreement) in the U.S. and a percentage in the low to mid-single digits of Net Sales in each country outside of the U.S., in each case
subject  to  specified  reductions  under  certain  conditions  as  described  in  the  KP415  License  Agreement.  The  Company  concluded  that  these  regulatory  milestones,  sales
milestones and royalty payments each contain a significant uncertainty associated with a future event. As such, these milestone and royalty payments are constrained at contract
inception  and  are  not  included  in  the  transaction  price  as  the  Company  could  not  conclude  that  it  is  probable  a  significant  reversal  in  the  amount  of  cumulative  revenue
recognized will not occur surrounding these milestone payments. At the end of each reporting period, the Company updates its assessment of whether the milestone and royalty
payments are constrained by considering both the likelihood and magnitude of the potential revenue reversal.

For example, in May 2020, the FDA accepted the Company’s NDA for AZSTARYS. Per the KP415 License Agreement, the Company received a regulatory milestone payment
of  $5.0  million  following  the  FDA’s  acceptance  of  the  AZSTARYS  NDA.  Since  the  FDA  accepted  the  Company’s  NDA  for  AZSTARYS  the  constraint  was  removed  and
revenue recognized. The associated revenue was allocated among the two performance obligations identified at contract inception. Since both performance obligations were
satisfied as of the end of the second quarter of 2020 the full $5.0 million payment was recognized as revenue during the second quarter of 2020.

For  the  year  ended  December  31,  2020,  the  Company  recognized  revenue  under  the  KP415  License  Agreement  of  $7.3  million.  In  accordance  with  the  guidance  provided
in ASC 340-40, Contracts with Customers, the Company capitalized approximately $2.8 million of incremental costs incurred in obtaining the KP415 License Agreement and
will  amortize  these  costs  as  the  revenue  associated  with  the  exclusive  worldwide  license,  reimbursement  of  out-of-pocket  third-party  research  and  development  costs  and
consulting services is recognized. As of December 31, 2020, the Company has recognized all of these incremental costs, $0.8 million of which was recognized in the year ended
December 31, 2020 and is recorded in the line item titled royalty and direct contract acquisition costs in the statement of operations. There was $12.8 million of revenue and
$1.9 million of associated direct contract acquisition costs recognized for the year ended December 31, 2019 related to the KP415 License Agreement. There was no deferred
revenue related to this agreement as of December 31, 2020 or December 31, 2019.

125

 
 
 
 
 
 
Consulting Arrangements

The Company enters into consulting arrangements with third-parties that fall under the scope of ASC 606.  These arrangements may require the Company to deliver various
rights,  services,  including  research  and  development  services,  regulatory  services  and/or  commercialization  support  services.  The  underlying  terms  of  these  arrangements
generally provide for consideration to the Company in the form of consulting fees and reimbursements of out-of-pocket third-party research and development, regulatory and
commercial costs.

Corium Consulting Agreement

The Corium Consulting Agreement is within the scope of ASC 606, as the transaction represents a contract with a customer where the participants function in a customer /
vendor relationship and are not exposed equally to the risks and rewards of the activities contemplated under the Corium Consulting Agreement. Using the concepts of ASC
606,  the  Company  identified  the  performance  of  consulting  services,  which  includes  the  reimbursement  to  the  Company  of  third-party  pass-through  costs,  as  its  only
performance obligation at inception. The Company further determined that the transaction price, at inception, under the agreement was $13.6 million which is the fair value of
the consulting services, including the reimbursement of third-party pass-through costs. The Company concluded that the regulatory milestone contains a significant uncertainty
associated with a future event. As such, this milestone is constrained at contract inception and is not included in the transaction price as the Company could not conclude that it
is probable a significant reversal in the amount of cumulative revenue recognized will not occur surrounding these milestone payments. At the end of each reporting period, the
Company updates its assessment of whether the milestone is constrained by considering both the likelihood and magnitude of the potential revenue reversal.

The Company determined that the performance of consulting services, including reimbursement of third-party pass-through costs, is a performance obligation that is satisfied
over time as the services are performed and the reimbursable costs are paid. As such, the revenue related to the performance obligation will be recognized as the consulting
services are performed and the services associated with the reimbursable third-party pass-through costs are incurred and paid by the Company, in accordance with the practical
expedient allowed under ASC 606 regarding an entity’s right to consideration from a customer in an amount that corresponds directly to the value to the customer of the entity’s
performance completed to date. As of December 31, 2020, the Company has recognized approximately 30% of the consulting services and third-party pass-through costs under
the Corium Consulting Agreement.

For the year ended December 31, 2020, the Company recognized revenue under the Corium Consulting Agreement of $3.9 million. There was no revenue recognized for the
year  ended  December  31,  2019  related  to  the  Corium  Consulting  Agreement.  As  of  December  31,  2020,  the  Company  had  deferred  revenue  related  to  this  agreement  of
$0.1 million. There was no deferred revenue related to this agreement as of December 31, 2019 as it was not entered into until July 2020.

Other Consulting Arrangements

For the year ended December 31, 2020, the Company recognized revenue under other consulting arrangements of $2.0. There was no revenue recognized from other consulting
arrangements for the year ended December 31, 2019. There was no deferred revenue from other from consulting arrangements as of December 31, 2020 or 2019.

Accounts and Other Receivables

Accounts  and  other  receivables  consists  of  receivables  under  the  KP415  License  Agreement  and  Corium  Consulting  Agreement,  as  well  as  receivables  related  to  other
consulting  arrangements,  income  tax  receivables  and  other  receivables  due  to  the  Company.  Receivables  under  the  KP415  License  Agreement  and  Corium  Consulting
Agreement are recorded for amounts due to the Company related to reimbursable third-party costs and performance of consulting services. These receivables, as well as the
receivables related to other consulting arrangements, are evaluated to determine if any reserve or allowance should be established at each reporting date. As of December 31,
2020, the Company had receivables related to the Corium Consulting Agreement in the amount of $2.1 million, other consulting arrangements in the amount of $0.4 million and
no receivables related to the KP415 License Agreement. As of December 31, 2019, the Company had receivables related to the KP415 License Agreement in the amount of
$1.6 million and receivables related to other consulting arrangements of $0.1 million. As of December 31, 2020 and 2019 no reserve or allowance for doubtful accounts has
been established.

Research and Development

Major  components  of  research  and  development  costs  include  cash  compensation,  stock-based  compensation,  depreciation  and  amortization  expense  on  research  and
development property and equipment, costs of preclinical studies, clinical trials and related clinical manufacturing, costs of drug development, costs of materials and supplies,
facilities cost, overhead costs, regulatory and compliance costs, and fees paid to consultants and other entities that conduct certain research and development activities on the
Company’s behalf. Costs incurred in research and development are expensed as incurred.

The  Company  records  nonrefundable  advance  payments  it  makes  for  future  research  and  development  activities  as  prepaid  expenses.  Prepaid  expenses  are  recognized  as
expense in the statements of operations as the Company receives the related goods or services.

The Company enters into contractual agreements with third-party vendors who provide research and development, manufacturing, and other services in the ordinary course of
business. Some of these contracts are subject to milestone-based invoicing and services are completed over an extended period of time. The Company records liabilities under
these contractual commitments when an obligation has been incurred. This accrual process involves reviewing open contracts and purchase orders, communicating with the
applicable personnel to identify services that have been performed and estimating the level of service performed and the associated cost when the Company has not yet been
invoiced  or  otherwise  notified  of  actual  cost.  The  majority  of  the  service  providers  invoice  the  Company  monthly  in  arrears  for  services  performed.  The  Company  makes
estimates of the accrued expenses as of each balance sheet date based on the facts and circumstances known. The Company periodically confirms the accuracy of the estimates
with the service providers and make adjustments, if necessary.

127

 
 
 
 
 
 
 
 
Patent Costs

Patent costs, including related legal costs, are expensed as incurred and recorded within general and administrative expenses on the statements of operations.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax basis of
assets and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to
taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. Valuation allowances are recorded to reduce deferred tax assets to the
amount the Company believes is more likely than not to be realized.

Uncertain tax positions are recognized only when the Company believes it is more likely than not that the tax position will be upheld on examination by the taxing authorities
based  on  the  merits  of  the  position.  The  Company  recognizes  interest  and  penalties,  if  any,  related  to  unrecognized  income  tax  uncertainties  in  income  tax  expense.  The
Company did not have any accrued interest or penalties associated with uncertain tax positions as of December 31, 2020 and 2019.

The Company files income tax returns in the United States for federal and various state jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal and
state and local income tax examinations for years prior to 2014, although carryforward attributes that were generated prior to 2017 may still be adjusted upon examination by
the Internal Revenue Service if used in a future period. No income tax returns are currently under examination by taxing authorities.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all stock-based payment awards made to employees, officers and directors based on the estimated fair values
of the awards as of the grant date. The Company records the value of the portion of the award that is ultimately expected to vest as expense over the requisite service period.
The Company also accounts for equity instruments issued to non-employees using a fair value approach under Accounting Standards Codification ("ASC") subtopic 505-50,
inclusive  of  the  modifications  made  by  Accounting  Standards  Update  ("ASU") 2018-07,  Compensation—Stock  Compensation  (Topic  718):  Improvements  to  Non-Employee
Share-Based Payment Accounting (“ASU 2018-17”). The Company values equity instruments and stock options granted using the Black-Scholes option pricing model.

Basic and Diluted Net Loss per Share of Common Stock

The Company uses the two-class method to compute net loss per common share because the Company has issued securities, other than common stock, that contractually entitle
the  holders  to  participate  in  dividends  and  earnings  of  the  Company.  The  two-class  method  requires  earnings  for  the  period  to  be  allocated  between  common  stock  and
participating securities based upon their respective rights to receive distributed and undistributed earnings. Holders of each series of the Company’s convertible preferred stock
and  select  warrants  are  entitled  to  participate  in  distributions,  when  and  if  declared  by  the  board  of  directors,  that  are  made  to  common  stockholders  and,  as  a  result,  are
considered participating securities.

Segment and Geographic Information

Operating segments are defined as components of an enterprise (business activity from which it earns revenue and incurs expenses) for which discrete financial information is
available and regularly reviewed by the chief operating decision maker ("CODM") in deciding how to allocate resources and in assessing performance. The Company’s CODM
is its Chief Executive Officer. The Company views its operations and manages its business as a single operating and reporting segment. All assets of the Company were held in
the United States as of December 31, 2020 and 2019.

Application of New or Revised Accounting Standards—Adopted

From time to time, the Financial Accounting Standards Board (the “FASB”) or other standard-setting bodies issue accounting standards that are adopted by the Company as of
the specified effective date.

In  April  2012,  President  Obama  signed  the  Jump-Start  Our  Business  Startups  Act  (the  “JOBS  Act”)  into  law.  The  JOBS  Act  contains  provisions  that,  among  other  things,
reduce certain reporting requirements for an emerging growth company. As an emerging growth company, the Company could have elected to adopt new or revised accounting
standards when they become effective for non-public companies, which typically is later than public companies must adopt the standards. The Company has irrevocably elected
not to take advantage of the extended transition period afforded by the JOBS Act and, as a result, will comply with new or revised accounting standards on the relevant dates on
which adoption of such standards is required for non-emerging growth companies.

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments—Credit  Losses  (Topic  326)—Measurement  of  Credit  Losses  on  Financial  Instruments  (“ASU  2016-
13”),  which  replaces  the  incurred  loss  impairment  methodology  with  a  methodology  that  reflects  expected  credit  losses  and  requires  consideration  of  a  broader  range  of
reasonable  and  supportable  information  to  inform  credit  loss  estimates.  This  update  applies  to  all  entities  holding  financial  assets  and  net  investment  in  leases  that  are  not
accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures,
reinsurance  receivables,  and  any  other  financial  assets  not  excluded  from  the  scope  that  have  the  contractual  right  to  receive  cash.  This  guidance  is  effective  for  financial
statements  issued  for  fiscal  years  beginning  after  December  15,  2019,  and  interim  periods  within  those  fiscal  years.  The  adoption  of ASU  2016-13  did  not  have  a  material
impact on the Company’s financial statements and disclosures.

In  August  2018,  the  FASB  issued  ASU  2018-13,  Fair  Value  Measurement  (Topic  820)—Disclosure  Framework—Changes  to  the  Disclosure  Requirements  for  Fair  Value
Measurement (“ASU 2018-13”), which modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, based on the concepts in the
FASB  Concepts  Statement,  Conceptual  Framework  for  Financial  Reporting—Chapter  8:  Notes  to  Financial  Statements,  which  the  FASB  finalized  on  August  28,  2018,
including  the  consideration  of  costs  and  benefits.  This  update  applies  to  all  entities  that  are  required,  under  existing  U.S.  GAAP,  to  make  disclosures  about  recurring  or
nonrecurring fair value measurements. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2019, and interim periods within
those fiscal years. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair
value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in
the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The adoption of ASU 2018-13 did
not have a material impact on the Company’s financial statements and disclosures.

Application of New or Revised Accounting Standards—Not Yet Adopted

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own
Equity (Subtopic 815-40); Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which addresses issues identified as a result of
the complexities associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. This update addresses, among other things,
the  number  of  accounting  models  for  convertible  debt  instruments  and  convertible  preferred  stock,  targeted  improvements  to  the  disclosures  for  convertible  instruments
and earnings-per-share (“EPS”) guidance and amendments to the guidance for the derivatives scope exception for contracts in an entity’s own equity, as well as the related EPS
guidance. This  update  applies  to  all  entities  that  issue  convertible  instruments  and/or  contracts  in  an  entity’s  own  equity. This  guidance  is  effective  for  financial  statements
issued for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning
after December 15, 2020, including interim periods within those fiscal years. FASB specified that an entity should adopt the guidance as of the beginning of its annual fiscal
year. The Company is currently evaluating the impact the adoption of ASU 2020-06 could have on the Company’s financial statements and disclosures.

In  June  2014,  the  Company  entered  into  a  $60  million  multi-tranche  credit  facility  (the  “Deerfield  Facility  Agreement”)  with  Deerfield  Private  Design  Fund  III,  LP
(“Deerfield”). At the time the Company entered into the Deerfield Facility Agreement, the Company borrowed the first tranche, which consisted of a term loan of $15 million
(the “Term Note”) and a senior secured loan of $10 million (the “Deerfield Convertible Note”).

Deerfield  is  no  longer  obligated  to  provide  the  Company  any  additional  disbursements  under  the  Deerfield  Facility  Agreement.  Deerfield  may  convert  any  portion  of  the
outstanding  principal  and  any  accrued  but  unpaid  interest  on  the  Deerfield  Convertible  Note  into  shares  of  the  Company’s  common  stock  at  an  initial  conversion  price
of $5.85 per share (the “Deerfield Note Put Option”). After giving effect to the Reverse Stock Split effected in December 2020, the conversion price became $93.60.

The Deerfield Convertible Note originally bore interest at 9.75% per annum, but was subsequently reduced to 6.75%. Interest accrued on the outstanding balance under the
Deerfield  Convertible  Note  was  due  quarterly  in  arrears.  The  Company  originally  had  to  repay  one-third  of  the  outstanding  principal  amount  of  the  Deerfield  Convertible
Note on the fourth and fifth anniversaries of the Deerfield Facility Agreement (June 2018 and June 2019). In June 2018, Deerfield agreed to convert the $3,333,333 of the
principal amount then due, plus $168,288 of accrued interest, into 37,410 shares of our common stock (as discussed below in the section entitled “Facility Agreement Waiver
and Fifth Amendment to Senior Secured Convertible Note”). In September 2019, the Company entered into an amendment with Deerfield in order to (i) reduce the interest rate
applicable  under  the  Deerfield  Facility  Agreement  from  9.75%  to  6.75%,  (ii)  provide  for  “payment  in  kind”  of  interest  on  the  Loans  (as  defined  in  the  Deerfield  Facility
Agreement),  and  (iii)  defer  the  Loan  payments  due  pursuant  to  the  Deerfield  Facility  Agreement  until  June  1,  2020  (as  discussed  below  in  the  section  entitled  “2021  Note
Exchange Effected in September 2019”). In December 2019, the Company entered into another amendment with Deerfield in order to (i) defer the Loan payments due pursuant
to the Deerfield Facility Agreement until March 31, 2021 and (ii) allow for the entries of additional debt and debt holders under the Deerfield Facility Agreement (as discussed
below in the section entitled “2021 Note Exchange Effected in December 2019”). The Company is also obligated to repay principal of the Deerfield Convertible Note in the
amount of $6,980,824 plus any capitalized interest to date on March 31, 2021. Prepayment of the outstanding balance is not allowed without written consent of Deerfield.

Pursuant to the Deerfield Facility Agreement, the Company issued to Deerfield 1,923,077 shares of Series D redeemable convertible preferred stock (“Series D Preferred”) as
consideration for the loans provided to the Company thereunder. Upon completion of the initial public offering, these shares of Series D Preferred automatically reclassified
into 256,410 shares of the Company’s common stock. After giving effect to the Reverse Stock Split effected in December 2020, the reclassified shares became 16,025 shares.

The  Company  also  issued  to  Deerfield  a  warrant  to  purchase  14,423,076  shares  of  Series  D  Preferred  at  an  initial  exercise  price  of  $0.78  per  share,  which  is  exercisable
until  June  2,  2024  (the  “Deerfield  Warrant”).  Upon  completion  of  the  Company’s  initial  public  offering,  the  Deerfield  Warrant  automatically  converted  into  a  warrant  to
purchase 1,923,077 shares of the Company’s common stock at an exercise price of $5.85 per share. After giving effect to the Reverse Stock Split effected in December 2020,
the shares issuable upon conversion of the warrant became 120,192 shares of common stock, and the exercise price of the Deerfield Warrant became $93.60 per share, which in
January 2021 was further adjusted to $46.25 per share in connection with the Company entering into the Inducement Letters (as defined in Note R) which triggered the anti-
dilution  provisions  of  the  Deerfield  Warrant.  This  warrant  qualifies  as  a  participating  security  under  ASC  Topic  260,  Earnings  per  Share,  and  is  treated  as  such  in  the  net
loss per share calculation (Note O). If a Major Transaction occurs (as defined in the Deerfield Facility Agreement) Deerfield may require the Company to redeem the Deerfield
Warrant for a cash amount equal to the Black-Scholes value of the portion of the Deerfield Warrant to be redeemed (the “Warrant Put Option”).

The  Company  recorded  the  fair  value  of  the  shares  of  Series  D  Preferred  to  debt  issuance  costs  on  the  date  of  issuance.  The  Company  also  recorded  the  fair  value  of  the
Deerfield Warrant and the embedded Warrant Put Option to debt discount on the date of issuance. The debt issuance costs and debt discount are amortized over the term of the
related debt and the expense is recorded as interest expense related to amortization of debt issuance costs and discount in the statements of operations.

Pursuant to the Deerfield Facility Agreement, the Company may not enter into specified transactions, including a debt financing in the aggregate value of $750,000 or more,
other than permitted indebtedness under the Deerfield Facility Agreement, a merger, an asset sale or any other change of control transaction or any joint venture, partnership or
other profit-sharing arrangement, without the prior approval of the Required Lenders (as defined in the Deerfield Facility Agreement). Additionally, if the Company were to
enter into a major transaction, including a merger, consolidation, sale of substantially all of its assets or other change of control transaction, Deerfield would have the ability to
demand  that  prior  to  consummation  of  such  transaction  the  Company  repay  all  outstanding  principal  and  accrued  interest  of  any  notes  issued  under  the  Deerfield  Facility
Agreement. Under each warrant issued pursuant to the Deerfield Facility Agreement, Deerfield has the right to demand that the Company redeem the warrant for a cash amount
equal to the Black-Scholes value of a portion of the warrant upon the occurrence of specified events, including a merger, an asset sale or any other change of control transaction.

The Deerfield Facility Agreement also includes high yield discount obligation protections that went into effect in June 2019. Going forward, if at any interest payment date our
outstanding indebtedness under the Deerfield Facility Agreement would qualify as an “applicable high yield discount obligation” under the Internal Revenue Code of 1986
(the” Code”) then the Company is obligated to prepay in cash on each such date the amount necessary to avoid such classification.

Issuance of 5.50% Senior Convertible Notes and Third Amendment to Senior Secured Convertible Note and Warrant

In  February  2016,  the  Company  issued  $86.3  million  aggregate  principal  amount  of  its  5.50%  Senior  Convertible  Notes  due  2021  (the  “2021  Notes”)  to  Cowen  and  RBC
Capital Markets, LLC, as representatives of the several initial purchasers (the “Initial Purchasers”), who subsequently resold the 2021 Notes to qualified institutional buyers (the
“Note Offering”) in reliance on the exemption from registration provided by Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”).

The 2021 Notes were issued pursuant to an indenture, dated as of February 9, 2016 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the
“Trustee”). Interest on the 2021 Notes was payable semi-annually in cash in arrears on February 1 and August 1 of each year, beginning on August 1, 2016, at a rate of 5.50%
per year. The 2021 Notes had an original maturity of February 1, 2021 unless earlier converted or repurchased.

The net proceeds from the Note Offering were approximately $82.8 million, after deducting the Initial Purchasers’ discount and estimated offering expenses. Concurrent with
the  Note  Offering,  the  Company  used  approximately  $18.6  million  of  the  net  proceeds  from  the  Note  Offering  to  repay  in  full  the  Term  Note,  plus  all  accrued  but  unpaid
interest, a make-whole interest payment and a prepayment premium on the Term Note.

The 2021 Notes were not redeemable prior to the maturity date, and no sinking fund was provided for the 2021 Notes. The 2021 Notes were convertible at an initial conversion
rate of 58.4454 shares of the Company’s common stock per $1,000 principal amount of the 2021 Notes, subject to adjustment under the Indenture, which is equal to an initial
conversion price of approximately $17.11 per share of common stock. After giving effect to the Reverse Stock Split effected in December 2020, the conversion rate of the 2021
Notes  would  be  approximately  3.6528  shares  of  the  Company’s  common  stock  per  $1,000  principal  amount  of  the  2021  Notes,  which  is  equal  to  a  conversion  price  of
approximately $273.76 per share.

If  the  Company  underwent  a  “fundamental  change”  (as  defined  in  the  Indenture),  holders  could  have  required  that  the  Company  repurchase  for  cash  all  or  any  portion  of
their 2021 Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2021 Notes to be repurchased, plus accrued and unpaid interest to, but
excluding, the fundamental change repurchase date.

The Indenture included customary terms and covenants, including certain events of default after which the 2021 Notes may be due and payable immediately.

As described in more detail below, in multiple exchanges occurring in October 2018, December 2019 and January 2020, all outstanding 2021 Notes were exchanged by the
holders thereof for either shares of our common stock or senior secured convertible promissory notes issued under the terms of the Deerfield Facility Agreement.

Facility Agreement Waiver and Fifth Amendment to Senior Secured Convertible Note

In June 2018, the Company entered into the Facility Agreement Waiver and Fifth Amendment (the “Fifth Amendment”) to the Deerfield Convertible Note with Deerfield. The
Fifth  Amendment,  among  other  things,  provided  that  (i)  $3,333,333  of  the  principal  amount,  plus  $168,288  of  accrued  interest,  of  the  Deerfield  Convertible  Note  issued
pursuant to the terms of the Deerfield Facility Agreement was converted into 37,410 shares of the Company’s common stock, with such principal conversion amount being
applied against and in full satisfaction of the amortization payment due June 2, 2018; (ii) Deerfield waived specified rights under the Deerfield Facility Agreement with regards
to  such  principal  and  interest  amount;  and  (iii)  amended  specified  provisions  of  the  Deerfield  Convertible  Note  as  they  relate  to  the  delivery  of  shares  of  the  Company’s
common stock in connection with any conversion of the Deerfield Convertible Note.

2021 Note Exchange Effected in October 2018

In October 2018, the Company entered into an exchange agreement (the “October 2018 Exchange Agreement”) with Deerfield and Deerfield Special Situations Fund, L.P. (the
“Deerfield Lenders”). Under the October 2018 Exchange Agreement, the Deerfield Lenders exchanged an aggregate of $9,577,000 principal amount of the 2021 Notes for an
aggregate of 9,577 shares of Series A Convertible Preferred Stock, par value $0.0001 (“Series A Preferred Stock”).

As  a  condition  to  closing  of  the  October  2018  Exchange  Agreement,  the  Company  filed  a  Certificate  of  Designation  of  Preferences,  Rights  and  Limitations  of  Series  A
Convertible Preferred Stock (the “Series A Certificate of Designation”) with the Secretary of State of the State Delaware, setting forth the preferences, rights and limitations of
the Series A Preferred Stock.

Each share of Series A Preferred Stock has an aggregate stated value of $1,000 and is convertible into shares of common stock at a price equal to $3.00 per share (subject to
adjustment  to  reflect  stock  splits  and  similar  events).  Immediately  following  the  exchange  under  the  October  2018  Exchange  Agreement,  there  were  an  aggregate  of
3,192,333 shares of common stock issuable upon conversion of the then outstanding Series A Preferred Stock (without giving effect to the limitation on conversion described
below). After giving effect to the Reverse Stock Split effected in December 2020, the conversion price of the Series A Preferred Stock would be $48.00 per share and shares of
common stock issuable upon conversion of the Series A Preferred Stock would be 199,519 shares of common stock. As of December 31, 2020, all 9,577 shares of Series A
Preferred Stock issued under the October 2018 Exchange Agreement have been converted into an aggregate 199,519 shares of the Company’s common stock.

2021 Note Exchange Effected in September 2019

In September 2019, the Company entered into an Exchange Agreement and Amendment to Facility Agreement (the “September 2019 Exchange Agreement”) with the Deerfield
Lenders.  Under  the  September  2019  Exchange  Agreement,  the  Company  issued  an  aggregate  of  93,742  shares  of  the  Company’s  common  stock  and  an  aggregate  of  1,576
shares  of  the  Company’s  Series  B-1  Convertible  Preferred  Stock,  par  value  $0.0001  per  share  (“Series  B-1  Preferred  Stock”)  (such  shares  of  common  stock  and  Series  B-
1  Preferred  Stock,  the  “Initial  Exchange  Shares”),  in  exchange  for  the  cancellation  of  an  aggregate  of  $3,000,000  principal  amount  of  the  Company’s  2021  Notes.  The
September 2019 Exchange Agreement provided the Deerfield Lenders the option to exchange up to an additional aggregate of $27,000,000 principal amount of the 2021 Notes
(the  “Optional  Exchange  Principal  Amount”)  for  shares  of  common  stock  or  shares  of  the  Company’s  Series  B-2  Convertible  Preferred  Stock,  par  value  $0.0001  per  share
(the  “Series  B-2  Preferred  Stock”  and,  together  with  the  Series  B-1  Preferred  Stock,  the  “Series  B  Preferred  Stock”),  subject  to  the  terms  and  conditions  set  forth  in  the
September 2019 Exchange Agreement, including limits as to the principal amount that can be exchanged prior to specified dates therein. If the Deerfield Lenders choose to
exchange any portion of the Optional Exchange Principal Amount for shares of Series B-2 Preferred Stock, such exchange would be effected at an exchange price of $1,000 per
share. If the Deerfield Lenders choose to exchange any portion of the Optional Exchange Principal Amount for shares of common stock, such exchange would be effected at an
exchange price equal to the greater of (i) $0.9494, or (ii) the average of the volume-weighted average price of the common stock on the principal securities exchange or trading
market on which the common stock is then trading on each of the 15 trading days immediately preceding such exchange. After giving effect to the Reverse Stock Split effected
in December 2020, the exchange price of the Optional Exchange Principal Amount would be $15.1904 or the average of the volume-weighted average price of the common
stock on the principal securities exchange or trading market on which the common stock is then trading on each of the 15 trading days immediately preceding such exchange.

As a condition to closing of the September 2019 Exchange Agreement, the Company filed a Certificate of Designation of Preferences, Rights and Limitations of Series B-
1  Convertible  Preferred  Stock  (the  “Series  B-1  Certificate  of  Designation”)  and  a  Certificate  of  Designation  of  Preferences,  Rights  and  Limitations  of  Series  B-
2 Convertible Preferred Stock (the “Series B-2 Certificate of Designation”) with the Secretary of State of the State Delaware, setting forth the preferences, rights and limitations
of the Series B-1 Preferred Stock and the Series B-2 Preferred Stock, respectively.

Each share of Series B-1 Preferred Stock has an aggregate stated value of $1,000 and is convertible into shares of common stock at a per share price equal to $0.9494 per share
(subject to adjustment to reflect stock splits and similar events). Immediately following the exchange under the September 2019 Exchange Agreement, there were an aggregate
of  1,659,996  shares  of  common  stock  issuable  upon  conversion  of  the  then  outstanding  Series  B-1  Preferred  Stock  (without  giving  effect  to  the  limitation  on  conversion
described below). After giving effect to the Reverse Stock Split effected in December 2020, the conversion price of the Series B-1 Preferred Stock would be $15.1904 and the
shares of common stock issuable upon conversion of the Series B-1 Preferred Stock would be 103,749 shares of common stock. Each share of Series B-2 Preferred Stock has an
aggregate stated value of $1,000 and is convertible into shares of common stock at a per share price equal to the greater of (i) $0.9494 (subject to adjustment to reflect stock
splits and similar events), or (ii) the average of the volume-weighted average prices of the common stock on the principal securities exchange or trading market on which the
common stock is then trading on each of the 15 trading days immediately preceding such exchange. Immediately following the exchange under the September 2019 Exchange
Agreement there was an aggregate of 28,439,015 shares of Common Stock issuable (i) in exchange of the Optional Exchange Principal Amount, or (ii) upon conversion of the
Series  B-2  Preferred  Stock  issuable  in  exchange  of  the  Optional  Exchange  Principal  Amount  (in  each  case  without  giving  effect  to  the  limitation  on  conversion  described
below). After giving effect to the Reverse Stock Split effected in December 2020, the conversion price of the Series B-2 Preferred Stock would be $15.1904 or the average of
the volume-weighted average price of the common stock on the principal securities exchange or trading market on which the common stock is then trading on each of the 15
trading days immediately preceding such exchange and the shares of stock issuable in exchange of the Optional Exchange Principal Amount or upon conversion of Series B-2
Preferred stock would be 1,777,437 shares of common stock.

135

 
 
 
 
 
 
The Series B Preferred Stock is convertible at any time at the option of the Deerfield Lenders; provided that the Deerfield Lenders are prohibited from converting shares of
Series B Preferred Stock into shares of common stock if, as a result of such conversion, such holders (together with certain affiliates and “group” members of such holders)
would beneficially own more than 4.985% of the total number of shares of common stock then issued and outstanding. The Series B Preferred Stock is not redeemable. In the
event of the Company’s liquidation, dissolution or winding up, the Deerfield Lenders will receive an amount equal to $0.0001 per share, plus any declared but unpaid dividends,
and thereafter will share ratably in any distribution of the Company’s assets with holders of common stock and with the holders of any shares of any other class or series of
capital stock of the Company entitled to share in such remaining assets of the Company (including the Series A Preferred Stock on an as-converted basis). With respect to rights
upon liquidation, the Series B Preferred Stock ranks senior to the common stock, on parity with the Series A Preferred Stock, if any is outstanding, and junior to existing and
future indebtedness. Except as otherwise required by law (or with respect to approval of certain actions involving the Company’s organizational documents that materially and
adversely affect the holders of Series B Preferred Stock), the Series B Preferred Stock does not have voting rights. The Series B Preferred Stock is not subject to any price-
based anti-dilution protections and does not provide for any accruing dividends, but provides that holders of Series B Preferred Stock will participate in any dividends on the
common stock on an as-converted basis (without giving effect to the limitation on conversion described above). The Series B-1 Certificate of Designation and the Series B-
2 Certificate of Designation also provide for partial liquidated damages in the event that the Company fails to timely convert shares of Series B-1 Preferred Stock or Series B-
2 Preferred Stock, respectively, into common stock in accordance with the applicable certificate of designation.

As of December 31, 2020, all 1,576 shares of Series B-1 Preferred Stock issued under the September 2019 Exchange Agreement have been converted into an aggregate of
103,749 shares of common stock, and there were no shares of Series B-2 Preferred Stock outstanding.

The  September  2019  Exchange  Agreement  also  amended  the  Deerfield  Facility  Agreement,  in  order  to  (i)  reduce  the  interest  rate  applicable  under  the  Deerfield  Facility
Agreement from 9.75% to 6.75%, (ii) provide for “payment in kind” of interest on the Loans (as defined in the Deerfield Facility Agreement), and (iii) defer the Loan payments
pursuant to the Deerfield Facility Agreement until June 1, 2020. The September 2019 Exchange Agreement contains customary representations, warranties and covenants made
by the Company and the Holders. The September 2019 Exchange Agreement also requires the Company to reimburse the Holders for up to $150,000 of expenses relating to the
transactions contemplated by the September 2019 Exchange Agreement.

The Company determined the changes to the Deerfield Facility Agreement met the definition of a troubled debt restructuring under ASC 470-60, Troubled Debt Restructurings
by Debtors,  as  the  Company  was  experiencing  financial  difficulties  and  Deerfield  granted  a  concession.  The  amendments  to  the  terms  of  the  Deerfield  Facility  Agreement
resulted  in  no  gain  on  restructuring  because  the  total  cash  outflows  required  under  the  amended  Deerfield  Facility  Agreement  exceeded  the  carrying  value  of  the  original
Deerfield Facility Agreement immediately prior to amendment. Prospectively, the Deerfield Facility Agreement, and the associated Deerfield Convertible Note will continue to
be carried net of the associated discount and debt issuance costs which will be amortized and recorded as interest expense using a modified effective interest rate based on the
amendments.

The changes to the 2021 Notes, under the September 2019 Exchange Agreement, were accounted for as a debt modification with the $2.3 million change in fair value of the
embedded  conversion  feature,  associated  with  the  Optional  Exchange  Principal  Amount,  recorded  as  an  increase  to  additional  paid  in  capital  and  as  a  debt  discount  to  be
amortized to interest expense under the effective interest method over the remaining term of the 2021 Notes.

2021 Note Exchange Effected in December 2019

In  December  2019,  the  Company  entered  into  the  December  2019  Exchange  Agreement  and  Amendment  to  Facility  Agreement,  Senior  Secured  Convertible  Notes  and
Warrants (the “December 2019 Exchange Agreement”) with the Deerfield Lenders and Delaware Street Capital Master Fund, L.P. (“DSC” and, collectively with the Deerfield
Lenders, the “December 2019 Holders”). Under the December 2019 Exchange Agreement, the Company issued senior secured convertible promissory notes under the Deerfield
Facility Agreement in the aggregate principal amount of $71,418,011 (the “December 2019 Notes”), in exchange for the cancellation of an aggregate of $71,418,011 principal
amount  and  accrued  interest  of  the  Company’s  2021  Notes.  Upon  entering  into  the  December  2019  Exchange  Agreement,  the  Company  agreed  to  pay  the  December  2019
Holders, in the aggregate, an interest payment of $745,011 which represents 50% of the accrued interest, as of December 18, 2019, on the 2021 Notes owned by the December
2019 Holders. The remainder of such interest was included in the principal amount of the December 2019 Notes.

The December 2019 Notes bear interest at 6.75% per annum. The December 2019 Notes are convertible into shares of the Company’s common stock at an initial conversion
price of $17.11 per share (which represents the conversion price of the 2021 Notes), subject to adjustment in accordance with the terms of the December 2019 Notes. As of the
date of issuance, the December 2019 Notes were convertible, by their terms, into an aggregate of 4,174,051 shares of the Company’s common stock. After giving effect to the
Reverse Stock Split effected in December 2020, the conversion price of the December 2019 Notes would be $273.76 per share and the shares of the Company’s common stock
issuable upon conversion of the December 2019 Notes would be 260,876 shares of common stock. The Company subsequently amended the December 2019 Notes to provide
that  such  notes  shall  be  convertible  into  shares  of  the  Company’s  common  stock  at  a  conversion  price  of  $93.60  per  share  (which  represents  the  conversion  price  of  the
Deerfield  Convertible  Note).  The  conversion  price  of  the  December  2019  Notes  will  be  adjusted  downward  if  the  Company  issues  or  sells  any  shares  of  common  stock,
convertible securities, warrants or options at a sale or exercise price per share less than the greater of the December 2019 Notes’ conversion price or the closing sale price of the
Company’s common stock on the last trading date immediately prior to such issuance, or, in the case of a firm commitment underwritten offering, on the date of execution of
the underwriting agreement between the Company and the underwriters for such offering. However, if the Company effects an “at the market offering” as defined in Rule 415
of the Securities Act, of its common stock, the conversion price of the December 2019 Notes will be adjusted downward pursuant to this anti-dilution adjustment only if such
sales  are  made  at  a  price  less  than  $93.60  per  share,  provided  that  this  anti-dilution  adjustment  will  not  apply  to  any  sales  made  under  (x)  the  2020  ELOC,  (y)  the  ATM
Agreement, or (z) the September 2019 Exchange Agreement (as amended). Notwithstanding anything in the contrary in the December 2019 Notes, the anti-dilution adjustment
of such notes shall not result in the conversion price of the December 2019 Notes being less than $9.328 per share. The December 2019 Notes are convertible at any time at the
option of the holders thereof, provided that a holder of a December 2019 Note is prohibited from converting such note into shares of the Company’s common stock if, as a
result  of  such  conversion,  such  holder  (together  with  certain  affiliates  and  “group”  members)  would  beneficially  own  more  than  4.985%  of  the  total  number  of  shares  of
common stock then issued and outstanding. However, the December 2019 Note issued to DSC, due to the fact DSC was a beneficial owner of more than 4.985% of the total
number  of  shares  of  the  Company’s  common  stock  then  issued  and  outstanding,  has  a  beneficial  ownership  cap  equal  to  19.985%  of  the  total  number  of  shares  of  the
Company’s  common  stock  then  issued  and  outstanding.  Pursuant  to  the  December  2019  Notes,  the  December  2019  Holders  have  the  option  to  demand  repayment  of  all
outstanding principal, and any unpaid interest accrued thereon, in connection with a Major Transaction (as defined in the December 2019 Notes), which shall include, among
others, any acquisition or other change of control of the Company; a liquidation, bankruptcy or other dissolution of the Company; or if at any time after March 31, 2021, shares
of the Company’s common stock are not listed on an Eligible Market (as defined in the December 2019 Notes). The December 2019 Notes are subject to specified events of
default, the occurrence of which would entitle the December 2019 Holders to immediately demand repayment of all outstanding principal and accrued interest on the December
2019 Notes. Such events of default include, among others, failure to make any payment under the December 2019 Notes when due, failure to observe or perform any covenant
under the Deerfield Facility Agreement (as defined below) or the other transaction documents related thereto (subject to a standard cure period), the failure of the Company to
be able to pay debts as they come due, the commencement of bankruptcy or insolvency proceedings against the Company, a material judgement levied against the Company and
a material default by the Company under the Deerfield Warrant, the December 2019 Notes or the Deerfield Convertible Note.

The December 2019 Exchange Agreement amends the Deerfield Facility Agreement in order to, among other things, (i) provide for the Deerfield Facility Agreement to govern
the December 2019 Notes received by the December 2019 Holders pursuant to the December 2019 Exchange Agreement, (ii) extend the maturity of the Deerfield Convertible
Note from February 14, 2020 and June 1, 2020, as applicable, to March 31, 2021, (iii) defer interest payments on the Deerfield Convertible Note until March 31, 2021 (which
such interest shall accrue as “payment-in-kind” interest), (iv) designate DSC as a Lender under (and as defined in the Deerfield Facility Agreement), (v) name Deerfield as the
“Collateral Agent” for all Lenders and (vi) modify the terms and conditions under which the Company may issue additional pari passu and subordinated indebtedness under the
Deerfield Facility Agreement (subject to certain conditions specified in the Deerfield Facility Agreement).

The December 2019 Exchange Agreement also amends and restates the Deerfield Convertible Note to conform the definitions of “Eligible Market” and “Major Transactions” to
the definition in the December 2019 Notes, to remove provisions that were only applicable prior to the Company’s initial public offering and to make certain other changes to
conform  to  the  December  2019  Notes.  The  conversion  price  for  the  Deerfield  Convertible  Note  remains  $93.60  per  share,  subject  to  adjustment  on  the  same  basis  as  the
December 2019 Notes.

The December 2019 Exchange Agreement also amends the Deerfield Warrant to conform the definitions of “Eligible Market” and “Major Transaction” in the Warrant with the
definitions of such terms in the December 2019 Notes.

137

 
 
 
 
 
 
 
 
The December 2019 Exchange Agreement contains customary representations, warranties and covenants made by the Company and the December 2019 Holders, including a
covenant of the Company to, upon request, use commercially reasonable efforts to use its technology to discover a product based upon a compound that may be identified by
the  Deerfield  Lenders  in  a  manner  that  is  reasonably  acceptable  to  the  Deerfield  Lenders,  or  one  of  their  affiliates,  with  the  terms  of  such  discovery  plan,  including  the
Company’s compensation thereunder, to be mutually agreed to by the parties.

In  connection  with  entering  into  the  December  2019  Exchange  Agreement,  on  December  18,  2019,  the  Company  amended  and  restated  that  certain  Guaranty  and  Security
Agreement, dated June 2, 2014, by and between the Company and the other parties thereto (the “GSA”) to, among other things, (i) provide that all of the notes will be secured
by the liens securing the indebtedness under the Deerfield Facility Agreement, and (ii) name Deerfield as the “Collateral Agent” under the GSA.

In  connection  with  entering  into  the  December  2019  Exchange  Agreement,  the  Company  also  entered  into  an  amendment  (the  “September  2019  Exchange  Agreement
Amendment”) to the September 2019 Exchange Agreement to, among other things, (i) amend and restate Annex I of the September 2019 Exchange Agreement to allow the
Deerfield Lenders to effect optional exchanges of the December 2019 Notes and the Deerfield Convertible Note under the terms of the September 2019 Exchange Agreement;
(ii) amend the common stock exchange price under the September 2019 Exchange Agreement to be a per share price equal to the greater of (x) $0.60, subject to adjustment to
reflect stock splits and similar events, or (y) the average of the volume-weighted average prices of the Company’s common stock on each of the 15 trading days immediately
preceding  such  exchange,  (iii)  provide  that  no  more  than  28,439,015  of  shares  of  the  Company’s  common  stock  shall  be  issued  pursuant  to  optional  exchanges  under  the
September 2019 Exchange Agreement (whether by common stock exchange or upon conversion of Series B-2 Shares (as defined in the September 2019 Exchange Agreement
Amendment)), subject to adjustment to reflect stock splits and similar events and (iv) eliminate limitations regarding the timing and aggregate amount of principal which may
be exchanged under the September 2019 Exchange Agreement. These changes in the September 2019 Exchange Agreement Amendment significantly modified the Optional
Exchange Principal Amount, as such after giving effect to the September Exchange Agreement Amendment the Optional Exchange Principal Amount ceases to exist the new
optional exchanges are referred to as the Deerfield Optional Conversion Feature. After giving effect to the Reverse Stock Split effected in December 2020, the exchange price
of the Deerfield Optional Conversion Feature would be $9.60 per share or the average of the volume-weighted average price of the common stock on the principal securities
exchange or trading market on which the common stock is then trading on each of the 15 trading days immediately preceding such exchange and the shares of the Company’s
common stock issued pursuant to the optional exchanges would be 1,777,437 shares of common stock.

In connection with entering into the September 2019 Amendment, the Company filed an amendment to the Series B-2 Certificate of Designation (the “Series B-2 Certificate of
Designation  Amendment”)  with  the  Secretary  of  State  of  the  State  Delaware.  The  Series  B-2  Certificate  of  Designation  Amendment  provides  that  each  share  of  the
Company’s Series B-2 preferred stock is convertible into shares of the Company’s common stock at a per share price equal to the common stock exchange price under the
September 2019 Exchange Agreement, which equals the greater of (i) $9.60 (subject to adjustment to reflect stock splits and similar events), or (ii) the average of the volume-
weighted average prices of the Company’s common stock on each of the 15 trading days immediately preceding such exchange.

As of December 31, 2020, the Deerfield Lenders have converted $17.1 million of principal under the December 2019 Notes into all 1,777,437 shares of common stock available
under the Deerfield Optional Conversion Feature.

The Company determined the changes to the Deerfield Convertible Note met the definition of a troubled debt restructuring under ASC 470-60, Troubled Debt Restructurings by
Debtors, as the Company was experiencing financial difficulties and Deerfield granted a concession. The amendments to the terms of the Deerfield Convertible Note resulted in
no  gain  on  restructuring  because  the  total  cash  outflows  required  under  the  amended  Deerfield  Convertible  Note  exceeded  the  carrying  value  of  the  original  Deerfield
Convertible Note immediately prior to amendment. Prospectively, the Deerfield Convertible Note will continue to be carried net of the associated discount and debt issuance
costs which will be amortized and recorded as interest expense using a modified effective interest rate based on the amendments.

The changes to the 2021 Notes, under the December 2019 Exchange Agreement, referred to after as the December 2019 Notes, were accounted for as a debt modification,
prospectively, the December 2019 Notes will be carried net of the associated discount and debt issuance costs which will be amortized and recorded as interest expense using a
modified effective interest rate based on the amendments.

2021 Note Exchange Effected in January 2020

In January 2020, the Company entered into the January 2020 Exchange Agreement (the “January 2020 Exchange Agreement”) with M. Kingdon Offshore Master Fund, LP
(“Kingdon”).  Under  the  January  2020  Exchange  Agreement,  the  Company  issued  a  senior  secured  convertible  note  in  the  aggregate  principal  amount  of  $3,037,354  (the
“January 2020 Note”) in exchange for the cancellation of an aggregate of $3,037,354 principal amount and accrued interest of the 2021 Note then owned by Kingdon. Upon
entering into the January 2020 Exchange Agreement, the Company agreed to pay Kingdon an interest payment of $37,354, which represents 50% of the accrued and unpaid
interest, as of January 13, 2020, on Kingdon’s 2021 Note. The remainder of such interest was included in the principal amount of the January 2020 Note.

The January 2020 Note was issued with substantially the same terms and conditions as the December 2019 Notes (as amended by the amendment described in more detail
below).

In  connection  with  entering  into  the  January  2020  Exchange  Agreement,  the  Company  entered  into  an  Amendment  to  Facility  Agreement  and  December  2019  Notes  and
Consent  (the  “December  2019  Note  Amendment”)  with  the  December  2019  Holders  that,  among  other  things,  (i)  amended  the  December  2019  Notes  to  (a)  reduce  the
Conversion Price (as defined in the December 2019 Notes) from $17.11 to $5.85 per share and (b) increased the Floor Price (as defined in the December 2019 Notes) from
$0.38 to $0.583 per share, and (ii) amended the Deerfield Facility Agreement to (x) provide for Kingdon to join the Deerfield Facility Agreement as a Lender (as defined in the
Deerfield Facility Agreement) and (y) provide that the 2020 Note and shall constitute a “Senior Secured Convertible Note” (as defined in the Deerfield Facility Agreement) for
purposes of the Deerfield Facility Agreement and other Transaction Documents (as defined in the Deerfield Facility Agreement). After giving effect to the Reverse Stock Split
effected in December 2020, the Conversion Price became $93.60 per share and the Floor Price became $9.328 per share.

The  changes  to  the  2021  Note,  under  the  January  2020  Exchange  Agreement,  referred  to  after  as  the  January  2020  Note,  were  accounted  for  as  a  debt  modification,
prospectively, the January 2020 Note will be carried net of the associated discount and debt issuance costs which will be amortized and recorded as interest expense using a
modified effective interest rate based on the amendments.

December 2020 Exchange Agreement and Amendment to Facility Agreement, Notes and Investors’ Rights Agreement

In  December  2020,  the  Company  entered  into  a  December  2020  Exchange  Agreement  and  Amendment  to  Facility  Agreement,  Notes  and  Investors’  Rights  Agreement,  as
amended  (the  “December  2020  Exchange  Agreement”)  with  the  Deerfield  Lenders,  DSC  and  Kingdon  (collectively,  the  “Facility  Agreement  Note  Holders”).  Under  the
December 2020 Exchange Agreement, the Company and the Facility Agreement Note Holders have agreed that (a) the Company will make a cash pre-payment of a portion of
principal  amount  of  the  Deerfield  Convertible  Note,  the  December  2019  Notes  and  the  January  2020  Note  (collectively,  the  “Facility  Agreement  Notes”)  to  the  Facility
Agreement Note Holders (the “Debt Payment”) equal to approximately $30.3 million, plus accrued interest if such payment is made on or after January 1, 2021, and (b) subject
to the satisfaction or waiver of certain conditions specified in the December 2020 Exchange Agreement, including the making of the Debt Payment, issue shares of its Series B-
2 Preferred Stock and warrants exercisable for shares of its common stock (the “Exchange Warrants”), in exchange for the cancellation of a portion of the principal amount of
the Facility Agreement Notes owned by the Facility Agreement Note Holders in an aggregate amount equal to the Debt Payment, plus the Q4 PIK Interest Payment (as defined
in the December 2020 Exchange Agreement) (such transaction, the “December 2020 Exchange”).

The December 2020 Exchange Agreement amends the Facility Agreement Notes to provide that the failure of the Company’s common stock to remain listed on an eligible
securities market will not constitute a “Major Transaction” unless such failure occurs after March 31, 2023.

Subject  to  the  satisfaction  or  waiver  of  certain  conditions  specified  in  the  December  2020  Exchange  Agreement,  including  the  making  of  the  Debt  Payment  and  the
consummation  of  the  exchange,  the  December  2020  Exchange  Agreement  will  amend  that  certain  Facility  Agreement  dated  as  of  June  2,  2014,  as  amended  (the  “Facility
Agreement”), by and among the Company and the Facility Agreement Note Holders in order to, among other things, (i) extend the maturity date of the Facility Agreement
Notes to March 31, 2023, (ii) provide for cash payments of interest on the Loans (as defined in the Facility Agreement) for the periods following July 1, 2021, and (iii) provide
for specified prepayment terms on the Loans.

The December 2020 Exchange Agreement amends that certain Amended and Restated Investors’ Rights Agreement, dated as of February 19, 2015 (the “IRA”), by and among
the Company, Deerfield and the other parties signatory thereto in order to, among other things, add Deerfield Special Situations Fund, L.P. as a party thereto and to give effect
to the issuance of the Exchange Warrants and the Company’s registration obligations under the December 2020 Exchange Agreement (as described in more detail below).

The Exchange Warrants to be issued pursuant to the December 2020 Exchange Agreement will be exercisable for a number of shares of the Company’s common stock equal to
75% of the shares of common stock issuable upon conversion of the Series B-2 Preferred Stock issued in the Exchange (without regard for any beneficial ownership limitations
included  therein).  The  Exercise  Warrants  will  be  subject  to  substantially  the  same  terms  and  conditions  as  the  warrants  issued  to  the  public  in  the  public  offering  of  the
Company’s securities contemplated pursuant to a registration statement on Form S-1, file no. 333-250945 (the “Public Offering”), with an exercise price equal to the exercise
price per share of the warrants issued in the Public Offering and will provide that the Facility Agreement Note Holders will be limited from exercising such Exchange Warrants
if,  as  a  result  of  such  exercise,  such  holders  (together  with  certain  affiliates  and  “group”  members  of  such  holders)  would  beneficially  own  more  than  4.985%  of  the  total
number of shares of the Company’s common stock then issued and outstanding.

140

 
 
 
 
 
 
 
 
The December 2020 Exchange Agreement contains customary representations, warranties and covenants made by the Company and the Facility Agreement Note Holders party
thereto, including a covenant of the Company for the benefit of the Facility Agreement Holders party to the Exchange Agreement to file a registration statement to register for
resale under the Securities Act the shares of common stock issuable upon exercise of the Exchange Warrants or conversion of the shares of Series B-2 Preferred Stock issued
pursuant to the terms of the December 2020 Exchange Agreement.

The transactions contemplated under the December 2020 Exchange Agreement, including the obligation to pre-pay any portion of the Facility Agreement Notes or to complete
the Exchange and the effectiveness of the amendments to the Facility Agreement, the Notes and the IRA, are subject to specified conditions of closing, including certain closing
of  the  Public  Offering,  the  filing  of  the  Restated  Series  B-2  Certificate  of  Designation  (as  defined  below)  and  the  approval  for  listing  of  the  Company’s  common  stock,
including the shares issuable upon conversion of the Series B-2 Preferred Stock and exercise of the Exchange Warrants, on the Nasdaq Capital Market.

As a condition to closing of the December 2020 Exchange Agreement, the Company has agreed to file an Amended and Restated Certificate of Designation of Preferences,
Rights  and  Limitations  of  Series  B-2  Convertible  Preferred  Stock  (the  “Restated  Series  B-2  Certificate  of  Designation”)  with  the  Secretary  of  State  of  the  State  Delaware,
setting forth the preferences, rights and limitations of the Series B-2 Preferred Stock.

Each share of Series B-2 Preferred Stock will have an aggregate stated value of $1,000 and will be convertible into shares of the Company’s common stock at a per share price
equal to the price per share to the public of the Company’s common stock in the Public Offering (subject to adjustment to reflect stock splits and similar events).

The Series B-2 Preferred Stock will be convertible at any time on or after the PDUFA Date (as defined in the Restated Series B-2 Certificate of Designation) at the option of the
holders thereof; provided that the holders thereof will be prohibited from converting shares of Series B-2 Preferred Stock into shares of the Company’s common stock if, as a
result of such conversion, such holders (together with certain affiliates and “group” members of such Holders) would beneficially own more than 4.985% of the total number of
shares  of  the  Company’s  common  stock  then  issued  and  outstanding.  The  Series  B-2  Preferred  Stock  will  not  be  redeemable.  In  the  event  of  the  Company’s  liquidation,
dissolution or winding up or a change in control of the Company (each, a “Liquidation Event”), the holders of Series B-2 Preferred Stock will receive, prior to any distribution
or payment on our common stock, an amount equal to the greater of (i) $1,000 per share (in the case of a change in control, transaction consideration with such value), or (ii)
the  amount  (in  the  case  of  a  change  in  control,  in  the  form  of  the  transaction  consideration)  per  share  each  such  holder  would  have  been  entitled  to  receive  if  every  share
of  Series  B-2  Preferred  Stock  had  been  converted  into  common  stock  immediately  prior  to  such  Liquidation  Event,  in  each  case,  plus  any  declared  but  unpaid  dividends
thereon. With respect to rights upon liquidation, the Series B-2 Preferred Stock will rank senior to the common stock, on parity with any Parity Securities (as defined in the
Restated  Series  B-2  Certificate  of  Designation)  and  junior  to  existing  and  future  indebtedness.  Except  as  otherwise  required  by  law  (or  with  respect  to  approval  of  certain
actions  involving  the  Company’s  organizational  documents  that  adversely  affect  the  holders  of  Series  B-2  Preferred  Stock  and  other  specified  matters  regarding  the  rights,
preferences and privileges of the Series B-2 Preferred Stock), the Series B-2 Preferred Stock will not have voting rights. The Series B-2 Preferred Stock will not be subject to
any  price-based  anti-dilution  protections  and  will  not  provide  for  any  accruing  dividends,  but  provides  that  holders  of  Series  B-2  Preferred  Stock  will  participate  in  any
dividends  on  the  Company’s  common  stock  on  an  as-converted  basis  (without  giving  effect  to  the  limitation  on  conversion  described  above).  The  Restated  Series  B-2
Certificate  of  Designation  will  also  provide  for  partial  liquidated  damages  in  the  event  that  the  Company  fails  to  timely  convert  shares  of  Series  B-2  Preferred  Stock  into
common stock in accordance with the Restated Series B-2 Certificate of Designation.

Debt Restructuring

In anticipation of the Public Offering (as defined and discussed in further detail in Note R), and to meet the Nasdaq Listing Requirements, the Company agreed in December
2020 to restructure the December 2019 Notes and the January 2020 Note in the aggregate principal amount of $60.8 million and the Deerfield Note in the principal amount of
$7.5 million (collectively the "the Facility Notes"). The total outstanding principal and accrued interest under the Facility Notes was $69.4 million as of December 31, 2020.

Under the terms of the December 2020 Exchange Agreement, the Company, on January 12, 2021, in connection with the closing of the Public Offering:

  ●

Exchanged $31.5 million of the outstanding principal and accrued interest on the Facility Notes for (i) 31,476.98412 shares of Series B-2 Preferred Stock, and (ii)
Exchange Warrants exercisable for 3,632,019 shares of the Company's common stock, and

  ● Made a payment of $30.3 million (the "Debt Payment"), in partial repayment of the remaining outstanding principal and accrued interest of the Facility Notes.

Following the completion of these transactions, the aggregate balance of principal and accrued interest remaining outstanding under the Facility Notes was approximately $7.6
million. With respect to this remaining outstanding balance under the Facility Notes, the December 2020 Exchange Agreement amended the terms of that debt to provide that:

  ● The maturity date was changed to March 31, 2023, and the debt is prepayable upon specified conditions, and

  ● Interest would accrue at the rate of 6.75% per annum, payable quarterly, would be added to principal until June 30, 2021, and then be payable in cash thereafter.

Based on the above transactions which occurred after the balance sheet date of December 31, 2020, but prior to the issuance of the financial statement the Company reclassified
the entire $68.2 million of convertible notes, and the associated debt issuance costs and discounts, from current to long-term on the balance sheet.

Payoff of Facility Agreement Notes and Termination of Facility Agreement

On February 8, 2021, the Company entered into a payoff letter with the Facility Note holders to pay off and thereby terminate the Deerfield Facility Agreement.

Pursuant to the payoff letter, the Company paid a total of $8.0 million to the Facility Note holders, representing the total principal balance and accrued interest outstanding and a
prepayment fee in repayment of our outstanding obligations under the Deerfield Facility Agreement.

For further discussion of the Debt Restructuring and the payoff of the Facility Notes and termination of the Deerfield Facility Agreement refer to Note R.

PPP Loan

On April 23, 2020, the Company received proceeds of $0.8 million from the PPP Loan under the PPP of the recently enacted CARES Act, a portion of which may be forgiven,
which the Company used to retain current employees, maintain payroll and make lease and utility payments. The PPP Loan matures on April 23, 2022 and bears annual interest
at a rate of 1.0%. Payments of principal and interest on the PPP Loan were originally deferred for the first six months of the PPP Loan term. Thereafter, the Company would
have been required to pay the lender equal monthly payments of principal and interest. As of December 31, 2020, $0.4 million of the PPP Loan is recorded on the balance sheet
in current portion of loans payable and $0.4 million is recorded in loan payable, less current portion. 

The CARES Act and the PPP provide a mechanism for forgiveness of up to the full amount borrowed. Under the PPP, the Company may apply for and be granted forgiveness
for all or part of the PPP Loan. The amount of loan proceeds eligible for forgiveness was originally based on a formula that takes into account a number of factors, including the
amount of loan proceeds used by the Company during the eight-week period after the loan origination for certain purposes, including payroll costs, interest on certain mortgage
obligations, rent payments on certain leases, and certain qualified utility payments, provided that at least 75% of the loan amount was used for eligible payroll costs. Subject to
the  other  requirements  and  limitations  on  loan  forgiveness,  only  loan  proceeds  spent  on  payroll  and  other  eligible  costs  during  the  covered  eight-week  period  would  have
qualified for forgiveness.

On June 5, 2020, President Trump signed into law the PPP Flexibility Act of 2020 (the “Flexibility Act”), which among other things provided the following important changes
to the PPP:

● Extended  the  covered  period  for  loan  forgiveness  from  eight  weeks  after  the  date  of  loan  disbursement  to  24  weeks  after  the  date  of  loan  disbursement,  providing
substantially greater flexibility for borrowers to qualify for loan forgiveness. Borrowers who had already received PPP loans retained the option to use an eight-week
covered period.

● Lowered the requirements that 75 percent of a borrower’s loan proceeds must be used for payroll costs and that 75 percent of the loan forgiveness amount must have
been spent on payroll costs during the 24-week loan forgiveness covered period to 60 percent for each of these requirements. If a borrower uses less than 60 percent of
the  loan  amount  for  payroll  costs  during  the  forgiveness  covered  period,  the  borrower  will  continue  to  be  eligible  for  partial  loan  forgiveness,  subject  to  at  least
60 percent of the loan forgiveness amount having been used for payroll costs.

● Provided a safe harbor from reductions in loan forgiveness based on reductions in full-time equivalent employees for borrowers that are unable to return to the same
level of business activity the business was operating at before February 15, 2020, due to compliance with requirements or guidance issued between March 1, 2020 and
December 31, 2020 by the Secretary of Health and Human Services, the Director of the Centers for Disease Control and Prevention, or the Occupational Safety and
Health Administration, related to worker or customer safety requirements related to COVID–19.

● Provided a safe harbor from reductions in loan forgiveness based on reductions in full-time equivalent employees, to provide protections for borrowers that are both
unable  to  rehire  individuals  who  were  employees  of  the  borrower  on  February  15,  2020,  and  unable  to  hire  similarly  qualified  employees  for  unfilled  positions  by
December 31, 2020.

● Increased  to  five  years  the  maturity  of  PPP  loans  that  are  approved  by  the  U.S.  Small  Business  Administration  (the  “SBA”)  (based  on  the  date  SBA  assigns  a  loan

number) on or after June 5, 2020.

● Extended the deferral period for borrower payments of principal, interest, and fees on PPP loans to the date that SBA remits the borrower’s loan forgiveness amount to

the lender (or, if the borrower does not apply for loan forgiveness, 10 months after the end of the borrower’s loan forgiveness covered period).

Based on the changes provided by the Flexibility Act the Company plans to take advantage of (i) the extended covered period for loan forgiveness from eight weeks to 24
weeks, (ii) the lowered requirement that a certain percentage of loan proceeds must be used for payroll costs from 75 percent to 60 percent, (iii) the extended deferral period for
payments of principal, interest and fees from six months after loan disbursement to 10 months after the SBA remits the borrower’s loan forgiveness amount to the lender and
(iv) take advantage of an safe harbor provisions as applicable. The Company will be required to repay any portion of the outstanding principal that is not forgiven, along with
accrued interest, in accordance with the amortization schedule described above. Based on the changes provided by the Flexibility Act the Company expects that substantially all
of the PPP loan will be forgiven, however, the Company cannot provide any assurance that the Company will be eligible for loan forgiveness or that any amount of the PPP
Loan will ultimately be forgiven by the SBA.

Letters of Credit

As of December 31, 2020, the Company has one irrevocable letter of credit supporting certain finance lease agreements. This letter of credit is guaranteed by a money market
account which is reported as restricted cash on the balance sheet.

Commitments and Contingencies

Legal Matters

From time to time, the Company is involved in various legal proceedings arising in the normal course of business. For some matters, a liability is not probable, or the amount
cannot be reasonably estimated and, therefore, an accrual has not been made. However, for such matters when it is probable that the Company has incurred a liability and can
reasonably estimate the amount, the Company accrues and discloses such estimates. As of December 31, 2020 and 2019, no accruals have been made related to commitments
and contingencies.

Lease Agreements

We have operating and finance leases for office space, laboratory facilities and various laboratory equipment, furniture and office equipment and leasehold improvements. Our
leases have remaining lease terms of 1 year to 5 years, some of which include options to extend the leases for up to 5 years, and some which include options to terminate the
leases within 1 year.

Florida

The Company leases office space in Florida, comprised of two contiguous office suites, under non-cancelable operating leases, which expire in August 2025 and February
2026, as to each space respectively, and include the right to extend the term of the leases for two successive five-year terms upon expiration. In February 2020, the Company
agreed to sublease office space in Florida, comprised of one of the two contiguous suites, under a non-cancelable operating lease, which expires in February 2026. In October,
2020, the Company agreed to terminate this sublease in exchange for a termination fee.

Iowa

The  Company  leases  office  and  laboratory  facilities  in  Iowa  under  a  non-cancelable  operating  lease.  The  Company’s  lease  for  its  Iowa  facilities  expires  in  September
2021 and includes a renewal option that could extend the lease for successive one-year terms upon expiration.

Virginia

The Company leases office and laboratory facilities in Virginia under a non-cancelable operating lease. The Company’s lease for its Virginia facilities expires in August 2021.

North Carolina

The Company leased office space in North Carolina under a non-cancelable operating lease. The original expiration date of the Company’s lease was May 2020. During the
second quarter of 2017, the Company subleased its office space in North Carolina under a non-cancelable operating lease to a third-party tenant. The sublease term with the
third-party runs concurrent with the lease term the Company has with the landlord. In October 2019, the Company terminated the head lease with the landlord and the
sublease with the subtenant so that the landlord and subtenant could enter directly into a lease.

In March 2020, the Company leased office space in North Carolina under a non-cancelable operating lease. The Company's lease for its North Carolina facilities expires in
March 2022.

Finance Lease

The  Company  leases  various  laboratory  equipment,  furniture  and  office  equipment  and  leasehold  improvements  that  are  accounted  for  as  finance  leases  and  that  require
ongoing payments, including interest expense. The finance leases are financed through various financial institutions and are collateralized by the underlying assets. As of
December 31, 2020 and 2019, the interest rates for assets under remaining finance leases range from 7.19% to 14.34%.

Supply Arrangement

As of  December 31, 2020 and 2019, the Company has one manufacturing arrangement that involves potential future expenditures related to research and development.

In  November  2009,  the  Company  entered  into  a  supply  agreement  (the  “Supply  Agreement”)  with  Johnson  Matthey  Inc.  (“JMI”)  whereby  JMI  has  agreed  to  supply  the
Company with all of the benzhydrocodone necessary for clinical trials and commercial sale for a price equal to JMI’s manufacturing cost and to provide process optimization
and development services for benzhydrocodone. The Company’s FDA-approved drug, APADAZ, contains benzhydrocodone. Expense of $3.2 million was recorded under this
agreement for the year ended December 31, 2019. The expense under this agreement for the year ended December 31, 2020 was negligible. The Company must purchase all of
its U.S. benzhydrocodone needs from JMI and JMI cannot supply benzhydrocodone to other companies. The term of the Supply Agreement extends as long as the Company
holds  a  valid  and  enforceable  patent  for  benzhydrocodone  or  until  the  tenth  anniversary  of  a  commercial  launch  of  a  FDA-approved  drug  incorporating  benzhydrocodone,
whichever date is later. Upon the expiration of such term, the agreement will automatically renew for a period of two years unless either party provides 12 months prior notice
of its intent not to renew. Under the agreement, JMI will receive a tiered-based royalty share on the net sales on the commercial sale of a FDA-approved drug incorporating
benzhydrocodone. No reliable estimate of the future payments can be made at this time.

Preferred Stock and Warrants 

Authorized, Issued, and Outstanding Preferred Stock

As of December 31, 2020 and 2019, the Company had 10,000,000 shares of authorized preferred stock, of which 9,578 shares were designated as Series A Preferred Stock,
1,576 shares were designated as Series B-1 Preferred Stock and 27,000 shares were designated as Series B-2 Preferred Stock. Of the designated preferred stock 9,577 shares of
Series A Preferred Stock and 1,576 shares of Series B-1 Preferred Stock were issued as of December 31, 2020 and 2019. No shares of Series A Preferred Stock or Series B-
1 Preferred Stock were outstanding as of December 31, 2020 and 2019. No shares of Series B-2 Preferred Stock were issued or outstanding as of December 31, 2020 and 2019.

In October 2018, the Company entered into the October 2018 Exchange Agreement. Under the October 2018 Exchange Agreement the Company issued to the Holders 9,577
shares of Series A Preferred Stock. Each share of Series A Preferred Stock has an aggregate stated value of $1,000 and is convertible into shares of common stock at a price
equal to $3.00 per share (subject to adjustment to reflect stock splits and similar events). Immediately following the exchange under the October 2018 Exchange Agreement,
there were an aggregate of 3,192,333 shares of common stock issuable upon conversion of the Series A Preferred Stock (without giving effect to the limitation on conversion
described  below),  and  as  of  December  31,  2020  all  issued  shares  of  Series A  Preferred  Stock  had  been  converted  into  shares  of  common  stock.  After  giving  effect  to  the
Reverse  Stock  Split  effected  in  December  2020,  the  conversion  price  of  the  Series  A  Preferred  Stock  would  be  $48.00  and  the  shares  of  common  stock  issuable  upon
conversion of the Series A Preferred stock would be 199,519 shares of common stock.

In September 2019, the Company entered into the September 2019 Exchange Agreement. Under the September 2019 Exchange Agreement the Company issued to the Holders
1,576 shares of Series B-1 Preferred Stock. Each share of Series B-1 Preferred Stock had an aggregate stated value of $1,000 and was convertible into shares of common stock
at a price equal to the greater of (i) $0.9494, or (ii) the average of the volume-weighted average price of the Common Stock on the principal securities exchange or trading
market on which the common stock is then trading on each of the 15 trading days immediately preceding such exchange (subject to adjustment to reflect stock splits and similar
events). Immediately following the exchange under the September 2019 Exchange Agreement, there were an aggregate of 1,659,996 shares of common stock issuable upon
conversion of the Series B-1 Preferred Stock (without giving effect to the limitation on conversion described below). After giving effect to the Reverse Stock Split effected in
December 2020, the conversion price of the Series B-1 Preferred Stock would be $15.1904 or the average of the volume-weighted average price of the common stock on the
principal securities exchange or trading market on which the common stock is then trading on each of the 15 trading days immediately preceding such exchange and the shares
of common stock issuable upon conversion of the Series B-1 Preferred Stock would be 103,749 shares of common stock. The Series B Preferred Stock is convertible at any
time at the option of the Holders; provided that the Holders are prohibited from converting shares of Series B Preferred Stock into shares of common stock if, as a result of such
conversion, such Holders (together with certain affiliates and “group” members of such Holders) would beneficially own more than 4.985% of the total number of shares of
common stock then issued and outstanding. The Series B Preferred Stock is not redeemable. In the event of the Company’s liquidation, dissolution or winding up, the Holders
will receive an amount equal to $0.0001 per share, plus any declared but unpaid dividends, and thereafter will share ratably in any distribution of the Company’s assets with
holders  of  common  stock  and  with  the  holders  of  any  shares  of  any  other  class  or  series  of  capital  stock  of  the  Company  entitled  to  share  in  such  remaining  assets  of  the
Company (including Series A Preferred Stock on an as-converted basis. With respect to rights upon liquidation, the Series B Preferred Stock ranks senior to the common stock,
on parity with the Series A Preferred Stock, if any is then outstanding, and junior to existing and future indebtedness. Except as otherwise required by law (or with respect to
approval  of  certain  actions  involving  the  Company’s  organizational  documents  that  materially  and  adversely  affect  the  holders  of  Series  B  Preferred  Stock),  the  Series  B
Preferred  Stock  does  not  have  voting  rights.  The  Series  B  Preferred  Stock  is  not  subject  to  any  price-based  anti-dilution  protections  and  does  not  provide  for  any  accruing
dividends, but provides that holders of Series B Preferred Stock will participate in any dividends on the common stock on an as-converted basis (without giving effect to the
limitation on conversion described above). The Series B-1 Certificate of Designation and the Series B-2 Certificate of Designation also provide for partial liquidated damages in
the event that the Company fails to timely convert shares of Series B-1 Preferred Stock or Series B-2 Preferred Stock, respectively, into Common Stock in accordance with the
applicable Certificate of Designation. As of December 31, 2020 all issued shares of Series B-1 Preferred Stock have been converted into shares of common stock.

As a condition to closing of the December 2020 Exchange Agreement, the Company has agreed to file the Restated Series B-2 Certificate of Designation with the Secretary of
State of the State Delaware, setting forth the preferences, rights and limitations of the Series B-2 Preferred Stock. Refer to Note G for further discussion.

Warrants

On June 2, 2014, pursuant to the terms of the Deerfield Facility Agreement, the Company issued the Deerfield Warrant to purchase 14,423,076 shares of Series D Preferred
(Note J). The Company recorded the fair value of the Deerfield Warrant as a debt discount and a warrant liability. The Deerfield Warrant, if unexercised, expires on the earlier
of  June  2,  2024,  or  upon  a  liquidation  event.  Upon  completion  of  the  Company’s  initial  public  offering  (the  “IPO”),  the  Deerfield  Warrant  automatically  converted  into  a
warrant  to  purchase  1,923,077  shares  of  the  Company’s  common  stock  at  an  exercise  price  of  $5.85  per  share. After  giving  effect  to  the  Reverse  Stock  Split  effected  in
December 2020, the exercise price of the Deerfield Warrant became $93.60 and the shares of the Company’s common stock issuable upon exercise of the Deerfield Warrant
became  120,192  shares  of  common  stock.  As  a  result  of  the  Warrant  Inducement  transaction  on  January  26,  2021  (refer  to  Note  R)  the  anti-dilution  provisions  within  this
Warrant  were  triggered  and  the  exercise  price  was  reduced  from  $93.60  per  share  to  $46.25  per  share.  The  Company  is  amortizing  the  debt  discount  over  the  term  of
the Deerfield Convertible Note and the expense is recorded as interest expense related to amortization of debt issuance costs and discount in the statements of operations.

The Company determined that the Deerfield Warrant should be recorded as a liability and stated at fair value at each reporting period upon inception. As stated above, upon
completion of the IPO, the Deerfield Warrant automatically converted into warrants to purchase the Company’s common stock. The Deerfield Warrant remains classified as a
liability and is recorded at fair value at each reporting period since it can be settled in cash. Changes to the fair value of the warrant liability are recorded through the unaudited
condensed statements of operations as a fair value adjustment (Note M).

In connection with a Collaboration and License Agreement (the “APADAZ License Agreement”) with KVK Tech, Inc. (“KVK”), in October 2018, the Company issued to KVK
a  warrant  to  purchase  up  to  500,000  shares  of  common  stock  of  the  Company  at  an  exercise  price  of  $2.30  per  share,  which  reflected  the  closing  price  of  the  Company’s
common stock on the Nasdaq Stock Market on the execution date of the APADAZ License Agreement (the “KVK Warrant”). The KVK Warrant is initially not exercisable for
any shares of common stock. Upon the achievement of each of four specified milestones under the KVK Warrant, the KVK Warrant will become exercisable for an additional
125,000 shares, up to an aggregate of 500,000 shares of the Company’s common stock. The exercise price and the number and type of shares underlying the KVK Warrant are
subject to adjustment in the event of specified events, including a reclassification of the Company’s common stock, a subdivision or combination of the Company’s common
stock, or in the event of specified dividend payments. The KVK Warrant is exercisable until October 24, 2023. Upon exercise, the aggregate exercise price may be paid, at
KVK’s election, in cash or on a net issuance basis, based upon the fair market value of the Company’s common stock at the time of exercise. After giving effect to the Reverse
Stock Split effected in December 2020, the exercise price of the KVK Warrant became $36.80 and the shares of common stock issuable upon exercise of the KVK Warrant
became 31,250 shares of common stock.

The Company determined that, since KVK qualifies as a customer under ASC 606, the KVK Warrant should be recorded as a contract asset and recognized as contra-revenue as
the Company recognizes revenue from the APADAZ License Agreement. In addition, the Company determined that the KVK Warrant qualifies as a derivative under ASC 815
and should be recorded as a liability and stated at fair value each reporting period. The Company calculates the fair value of the KVK Warrant using a probability-weighted
Black-Scholes option pricing model. Changes in fair value resulting from changes in the inputs to the Black Scholes model are accounted for as changes in the fair value of the
derivative under ASC 815 and are recorded as fair value adjustment related to derivative and warrant liability in the statements of operations. Changes in the number of shares
that  are  expected  to  be  issued  are  treated  as  changes  in  variable  consideration  under  ASC  606  and  are  recorded  as  a  change  in  contract  asset  in  the  balance  sheets.  As  of
December 31, 2020 and 2019, a contract asset of $0.4 million is recorded in other long-term assets on the balance sheets related to the KVK Warrant.

Stock-Based Compensation

The Company maintains a stock-based compensation plan (the “Incentive Stock Plan”) that governs stock awards made to employees and directors prior to completion of the
IPO.  

In November 2014, the Board of Directors of the Company ("the Board"), and in April 2015, the Company’s stockholders, approved the Company’s 2014 Equity Incentive Plan
(the “2014 Plan”), which became effective in April 2015. The 2014 Plan provides for the grant of stock options, other forms of equity compensation, and performance cash
awards. The maximum number of shares of common stock that may be issued under the 2014 Plan is 408,167 as of December 31, 2020. The number of shares of common stock
reserved  for  issuance  under  the  2014  Plan  will  automatically  increase  on  January  1  of  each  year,  beginning  on  January  1,  2016,  and  ending  on  and  including  January  1,
2024, by 4% of the total number of shares of the Company’s capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined
by the Board. Pursuant to the terms of the 2014 Plan, on January 1, 2021, the common stock reserved for issuance under the 2014 Plan automatically increased by 181,492
shares.

During  2020,  the  Company  granted  to  certain  consultants  fully  vested  restricted  stock  awards  (“RSAs”)  under  the  2014  Plan.  The  RSAs  were  granted  as  compensation  in
accordance with each consultants consulting agreement for services performed during 2020. For the year ended December 31, 2020, RSAs were granted for a total of 10,247
shares of common stock.

During  2019,  the  Company  granted  to  each  non-employee  member  of  the  Company’s  board  of  directors  (each  a  “non-employee  Director”)  two  separate  fully  vested  RSAs
under the 2014 Plan. The RSAs were granted in lieu of the quarterly cash compensation payable under the Company’s Third Amended and Restated Non-Employee Director
Compensation Policy to each non-employee Director for service as a member of the Company’s board of directors, and applicable committees thereof, for the first and second
quarters  of  2019.  For  the  year  ended  December  31,  2019,  RSAs  were  granted  for  a  total  of  5,104  shares  of  common  stock.  In  addition,  the  Company  granted  to  a
consultant fully vested RSAs under the 2014 Plan. The RSAs were granted as compensation in accordance with the consultant's consulting agreement for services performed
during 2019.

During  the  year  ended  December  31,  2020,  stock  options  to  acquire  279  shares  of  common  stock  were  exercised  for  approximately  $2,000  with  an  intrinsic  value  of
approximately $1,000. During the year ended December 31, 2019 no stock options were exercised.

Stock-based  compensation  expense  recorded  under  the  Incentive  Stock  Plan  and  the  2014  Plan  is  included  in  the  following  line  items  in  the  accompanying  statements  of
operations (in thousands):

The Company estimates the fair value of stock options using the Black-Scholes option-pricing model, which requires the use of subjective assumptions, including the expected
term of the option, the expected stock price volatility, expected dividend yield and the risk-free interest rate for the expected term of the option. The expected term represents
the period of time the stock options are expected to be outstanding. Due to the lack of sufficient historical exercise data to provide a reasonable basis upon which to otherwise
estimate the expected term of the stock options, the Company uses the simplified method to estimate the expected term for its “plain vanilla” stock options. Under the simplified
method, the expected term of an option is presumed to be the mid-point between the vesting date and the end of the contractual term. Some options, for example those that have
exercise prices in excess of the fair value of the underlying stock, are not considered “plain vanilla” stock options. For these options, the Company uses an expected term equal
to the contractual term of the option. Expected volatility for options granted prior to the second anniversary of the IPO is based on a blend of historical volatilities for publicly
traded stock of comparable companies and the Company over the estimated expected term of the stock options. For options granted after the second anniversary of the IPO,
expected volatility is based on the Company’s historical volatility over the estimated expected term of the stock options. The Company assumes no dividend yield because
dividends are not expected to be paid in the near future, which is consistent with the Company’s history of not paying dividends.

The Company recognizes compensation expense related to stock-based payment transactions upon satisfaction of the requisite service or vesting requirements. Forfeitures are
estimated at the time of grant and revised based on actual forfeitures, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Using  the  Black-Scholes  option-pricing  model,  the  weighted-average  fair  value  of  awards  granted  during  the  years  ended  December  31,  2020  and  2019,  fair  value  was
$5.00 and $22.88 per share, respectively. The assumptions used to estimate fair value are as follows:

Risk-free interest rate
Expected term (in years)
Expected volatility
Expected dividend yield

Fair Value of Financial Instruments

The carrying  amounts  of  certain  financial  instruments,  including  cash  and  cash  equivalents,  restricted  cash  and  accounts  payable  and  accrued  expenses,  approximate  their
respective fair values due to the short-term nature of such instruments.

The fair value of the Deerfield Convertible Note was $7.3 million and $6.0 million, respectively, as of December 31, 2020 and 2019. The fair value of the December 2019
Notes was $56.2 million and $57.0 million, respectively, as of December 31, 2020 and 2019. The fair value of the January 2020 Note was $3.1 million as of December 31, 2020
and the fair value of the 2021 Notes was $2.4 million as of December 31, 2019. The Deerfield Convertible Note, December 2019 Notes, January 2020 Note and 2021 Notes fall
within Level 3 of the fair value hierarchy as their value is based on the credit worthiness of the Company, which is an unobservable input. The Company used a Tsiveriotis-
Fernandes model to value the Deerfield Convertible Note and December 2019 Notes as of December 31, 2020 and 2019. The Company also used a Tsiveriotis-Fernandes model
to value the January 2020 Note as of December 31, 2020 and the 2021 Notes as of December 31, 2019.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level in which to classify them for
each  reporting  period.  This  determination  requires  significant  judgments  to  be  made.  The  following  table  summarizes  the  conclusions  reached  regarding  fair  value

The  Company’s  Deerfield  Warrant  liability,  embedded  Warrant  Put  Option,  embedded  Deerfield  Note  Put  Option  and  the  fundamental  change  and  the  make-whole  interest
provisions  embedded  in  the  2021  Notes  are  measured  at  fair  value  on  a  recurring  basis.  As  of  December  31,  2020  and  December  31,  2019,  the  Deerfield  Warrant
liability, embedded Warrant Put Option and the embedded Deerfield Note Put Option are reported on the balance sheets in derivative and warrant liability. The Company used a
Monte Carlo simulation to value the Deerfield Warrant liability, embedded Warrant Put Option and the embedded Deerfield Note Put Option as of December  31,  2020 and
December 31, 2019. The Company also used a Monte Carlo simulation to value the fundamental change and make-whole interest provisions embedded in the 2021 Notes as of
December  31,  2019.  Significant  unobservable  inputs  used  in  measuring  the  fair  value  of  these  financial  instruments  included  the  Company’s  estimated  enterprise  value,  an
estimate  of  the  timing  of  a  liquidity  or  fundamental  change  event  and  a  present  value  discount  rate.  Changes  in  the  fair  value  of  the  Deerfield Warrant  liability,  embedded
Warrant Put Option and the embedded Deerfield Note Put Option are reflected in the statements of operations for the years ended December 31, 2020 and 2019 as a fair value
adjustment  related  to  derivative  and  warrant  liability.  In  addition,  changes  in  the  fair  value  of  the  fundamental  change  and  make-whole  interest  provisions  embedded  in
the 2021 Notes are reflected in the statements of operations for the year ended December 31, 2019 as a fair value adjustment related to derivative and warrant liability.

The derivative liability for the Deerfield Warrant was $230,000 and $77,000 at December 31, 2020 and 2019, respectively. The derivative liability for the embedded Warrant
Put  Option  was  $25,000  and  $19,000  at  December  31,  2020  and  2019,  respectively.  The  derivative  liability  for  the  Deerfield  Note  Conversion  Feature  had  no  value  at
December 31, 2020 or 2019, respectively. A 10% increase in the enterprise value would result in an increase of $29,000 in the estimated fair value of the Deerfield Warrant
liability,  an  increase  of  $8,000  in  the  estimated  fair  value  of  the  embedded  Warrant  Put  Option  liability  and  no  change  in  the  estimated  fair  value  of  the  Deerfield  Note
Conversion  Feature  liability.  In  addition,  the  Company  assumed  a  weighted-average  probability  of  a  liquidity  event  occurring  of  approximately  87%  with  an  estimated
probability-weighted  value  of  approximately  $45.3  million  and  a  weighted-average  probability  of  a  fundamental  change  event  occurring  of  approximately  47%  with  an
estimated probability-weighted value of approximately $200 million, respectively, with estimated timing in each scenario of Q1 2021. The Company also assumed a present
value discount rate of approximately 27% in its analysis, which approximates the estimated credit spread of the Company at the date of the latest debt financing event which is
most closely related to relative notes.    

The Company’s KVK Warrant liability is measured at fair value on a recurring basis. As of December 31, 2020 and December 31, 2019, the KVK Warrant liability is reported
on the balance sheets in derivative and warrant liability. The Company estimates the fair value of the KVK Warrant using a probability-weighted Black-Scholes option-pricing
model, which requires the use of subjective assumptions, including the expected term of the warrant, the expected stock price volatility, expected dividend yield and the risk-
free interest rate for the expected term of the warrant. The expected term represents the period of time the warrant is expected to be outstanding. For the KVK Warrant, the
Company used an expected term equal to the contractual term of the warrant. Expected volatility is based on the Company's historical volatility since the IPO. The Company
assumes no dividend yield because dividends are not expected to be paid in the near future, which is consistent with the Company’s history of not paying dividends. Changes in
the fair value of the KVK Warrant liability are reflected in the statements of operations for the years ended December 31, 2020 and 2019 as a fair value adjustment related to
derivative and warrant liability.

In  assessing  the  realizability  of  deferred  tax  assets,  management  considers  whether  it  is  more  likely  than  not  that  some  portion  or  all  of  the  deferred  tax  assets  will  not be
realized.  The  ultimate  realization  of  deferred  tax  assets  is  dependent  upon  the  generation  of  future  taxable  income  during  the  periods  in  which  those  temporary  differences
become  deductible.  Management  considers  the  scheduled  reversal  of  deferred  tax  liabilities,  projected  future  taxable  income  and  tax  planning  strategies  in  making  this
assessment.  Based  upon  the  level  of  historical  taxable  income  and  projections  for  future  taxable  income  over  the  periods  in  which  the  deferred  tax  assets  are  deductible,
management believes it is more likely than not that the Company will not realize the benefits of these deductible differences in the future.

The Company also has certain state net operating loss carryforwards totaling $211.3 million, $145.4 million of which, if not utilized, will begin to expire in 2027 and $65.9
million of which have no expiration date. Due to potential ownership changes that may have occurred or would occur in the future, Internal Revenue Code Section 382 may
place additional limitations on the Company’s ability to utilize the net operating loss carryforward.

ASC 740-10, Accounting for Uncertainty in Income Taxes, uses the term “more likely than not” to evaluate whether or not a tax position will be sustained upon examination.
The Company has not identified any tax positions that do not meet the more likely than not threshold.

On March 27, 2020, the CARES Act was enacted into law in response to the COVID-19 pandemic. The Company has evaluated the various income and payroll tax provisions
and expects little or no impact to income tax expense.

O.

Net Loss Per Share

Under the two-class method, for periods with net income, basic net income per share of common stock is computed by dividing the net income attributable to shares of common
stock by the weighted average number of shares of common stock outstanding during the period. Net income attributable to shares of common stock is computed by subtracting
from net income the portion of current period earnings that participating securities would have been entitled to receive pursuant to their dividend rights had all of the period’s
earnings been distributed. No such adjustment to earnings is made during periods with a net loss as the holders of the participating securities have no obligation to fund losses.
Diluted net loss per share of common stock is computed under the two-class method by using the weighted average number of shares of common stock outstanding plus the
potential dilutive effects of stock options and warrants. In addition, the Company analyzes the potential dilutive effect of the outstanding convertible securities under the if-
converted method when calculating diluted loss per share of common stock in which it is assumed that the outstanding convertible securities convert into common stock at the
beginning of the period or date of issuance, if the convertible security was issued during the period. The Company reports the more dilutive of the approaches (two-class or if-
converted) as its diluted net loss per share of common stock during the period.

The following table summarizes the computation of basic and diluted net loss and net loss per share of common stock of the Company (in thousands, except share and per share
amounts):

Net loss - basic and diluted
Weighted average number of shares of common stock - basic and diluted
Net loss per share - basic and diluted

Diluted net loss per share of common stock is the same as basic net loss per share of common stock for the years ended December 31, 2020 and 2019 because the effects of
potentially dilutive items were anti-dilutive for the respective periods. The following securities, presented on a common stock equivalent basis, have been excluded from the

Severance Expense

In February 2020, the Company eliminated the chief business officer role and Gordon K. Johnson separated from the Company. In connection with his separation, Mr. Johnson
is entitled to severance benefits as documented in his Amended and Restated Employment Agreement entered into in June 2015. The severance benefits consist of personnel
and other related charges of approximately $0.4 million and stock compensation expense of approximately $0.4 million related to the acceleration of vesting on unvested shares
subject  to  certain  stock  options.  These  severance  benefits  are  presented  as  severance  expense  in  the  statements  of  operations  for  the  year  ended  December  31,  2020.  As  of
December 31, 2020, the Company had accrued severance expense recorded within accounts payable and accrued expenses in the amount of $0.1 million. As of and for the year
ended December 31, 2019, there was no accrued severance or severance expense, respectively.

Q.

Employee Benefit Plan

The Company has a 401(k) retirement plan (the “401(k) Plan”) that covers substantially all employees. The Company may provide  a  discretionary  match  with  a  maximum
amount of 4% of the participant’s compensation, which vests immediately. The Company made matching contributions under the 401(k) Plan of $145,000 and $133,000 for the
years ended December 31, 2020 and 2019, respectively.

The Company has a discretionary profit sharing plan (the “Profit Sharing Plan”) that covers all employees. Employees become eligible participants in the Profit Sharing Plan
once they have provided three years of service to the Company. The Company made no contributions to the Profit Sharing Plan in 2020 or 2019.

Subsequent Events

Underwriting Agreement

On January 8, 2021, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Roth Capital Partners, LLC (the “Underwriter” or "Roth"), to
issue and sell 6,765,463 shares of common stock of the Company, pre-funded warrants to purchase 926,844 shares of common stock and warrants to purchase 7,692,307 shares
of  common  stock  at  an  exercise  price  per  share  of  $6.50  in  an  underwritten  public  offering  (the  “Public  Offering”)  pursuant  to  a  Registration  Statement  on  Form  S-
1 (File No. 333-250945) and a related prospectus, in each case filed with the Securities and Exchange Commission (the “SEC”). The offering price to the public is $6.50 per
share of common stock and accompanying warrant, representing a public offering price of $6.4999 per share of common stock and $0.0001 per related warrant. In addition, the
Company granted the Underwriter an option to purchase, for a period of 45 days, up to an additional 1,153,846 shares of the Company’s common stock and/or warrants to
purchase up to an additional 1,153,846 shares of the Company’s common stock.

On January 8, 2021, the Underwriter exercised its over-allotment option, in part, for warrants to purchase 754,035 shares of the Company’s common stock. Further on February
1,  2021,  the  Underwriter  again  exercised  its  over-allotment  option  to  purchase  374,035  shares  of  common  stock.  On  February  3,  2021,  we  closed  the  underwriter's  partial
exercise of its over-allotment option.

On  January  12,  2021,  the  Company  closed  the  Public  Offering.  The  aggregate  gross  proceeds  to  the  Company  from  the  Public  Offering,  including  over-allotment,  totaled
approximately $52.4 million, before deducting underwriting discounts and commissions and offering expenses payable by the Company.

Pre-Funded Warrants

On January 12, 2021, pursuant to the terms of the Underwriting Agreement, the Company issued pre-funded warrants to purchase 926,844 shares of the Company’s common
stock to specified investors in the Public Offering.

Duration and Exercise Price

Each  pre-funded  warrant  has  an  initial  exercise  price  per  share  equal  to  $0.0001.  The  pre-funded  warrants  will  be  immediately  exercisable  and  will  not  expire  prior  to
exercise. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits,
reorganizations or similar events affecting the Company’s common stock.

Exercisability

The pre-funded warrants are exercisable, at the option of each holder, in whole or in part, by delivering to the Company a duly executed exercise notice accompanied by
payment in full for the number of shares of common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together
with its affiliates) may not exercise any portion of the pre-funded warrant to the extent that the holder would own more than 4.99% of the Company’s outstanding common
stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to the Company, the holder may increase the amount of beneficial ownership
of outstanding stock after exercising the holder’s pre-funded warrants up to 9.99% of the number of shares of the Company’s common stock outstanding immediately after
giving  effect  to  the  exercise,  as  such  percentage  ownership  is  determined  in  accordance  with  the  terms  of  the  pre-funded  warrants  and  Delaware  law.  Purchasers  of  pre-
funded warrants may also elect prior to the issuance of the pre-funded warrants to have the initial exercise limitation set at 9.99% of the Company’s outstanding common
stock.

Cashless Exercise

In lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the aggregate exercise price, the holder may elect
instead  to  receive  upon  such  exercise  (either  in  whole  or  in  part)  the  net  number  of  shares  of  common  stock  determined  according  to  a  formula  set  forth  in  the  pre-
funded warrants.

Rights as a Stockholder

Except  as  otherwise  provided  in  the  pre-funded  warrants  or  by  virtue  of  such  holder’s  ownership  of  shares  of  the  Company’s  common  stock,  the  holders  of  the  pre-
funded  warrants  do  not  have  the  rights  or  privileges  of  holders  of  common  stock  with  respect  to  the  shares  of  common  stock  underlying  the  pre-
funded  warrants,  including  any  voting  rights,  until  they  exercise  their  pre-funded  warrants.  The  pre-funded  warrants  provide  that  holders  have  the  right  to  participate  in
distributions or dividends paid on the Company’s common stock.

Fundamental Transaction

In  the  event  of  a  fundamental  transaction,  as  described  in  the  pre-funded  warrants  and  generally  including  any  reorganization,  recapitalization  or  reclassification  of  the
Company’s common stock, the sale, transfer or other disposition of all or substantially all of the Company’s properties or assets, the Company’s consolidation or merger with
or into another person, the acquisition of more than 50% of the Company’s outstanding common stock, or any person or group becoming the beneficial owner of 50% of the
voting  power  represented  by  the  Company’s  outstanding  common  stock,  the  holders  of  the  pre-funded  warrants  will  be  entitled  to  receive  upon  exercise  of  the  pre-
funded warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the pre-funded warrants immediately prior
to such fundamental transaction.

As of March 11, 2021, all pre-funded warrants have been exercised for 926,841 shares of common stock and gross proceeds of approximately $72.

Warrants to Purchase Common Stock

On January 12, 2021, pursuant to the terms of the Underwriting Agreement and December 2020 Exchange Agreement (as defined below), the Company issued warrants to
purchase 12,078,361 shares of the Company’s common stock (collectively, the “Warrants”) in the Public Offering and in connection with the transactions contemplated under
the December 2020 Exchange Agreement.

Duration and Exercise Price

The Warrants are exercisable from and after the date of their issuance and expire on the fifth anniversary of such date, at an exercise price per share of common stock equal to
$6.50 per share. The holder of a Warrant will not be deemed a holder of the underlying common stock until the Warrant is exercised. No fractional shares of common stock
will  be  issued  in  connection  with  the  exercise  of  Warrant.  Instead,  for  any  such  fractional  share  that  would  have  otherwise  been  issued  upon  exercise  of  a  Warrant,  the
Company will round such fraction up to the next whole share.

Exercisability

The Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to the Company a duly executed exercise notice, provided that payment in
full  for  the  number  of  shares  of  the  Company’s  common  stock  purchased  upon  such  exercise  is  delivered  to  the  Company  in  accordance  with  the  terms  of  the  Warrants
(except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Warrant to the extent that the holder
and  its  affiliates  and  any  other  person  or  entities  with  which  such  holder  would  constitute  a  Section  13(d)  “group”  would  own  more  than  4.985%  of  the  Company’s
outstanding common stock immediately after exercise.

Cashless Exercise

If, at the time a holder exercises its Warrants, a registration statement registering the issuance of the shares of common stock underlying such Warrant under the Securities Act
is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to the Company upon such
exercise  in  payment  of  the  aggregate  exercise  price,  the  holder  may  elect  instead  to  receive  upon  such  exercise  (either  in  whole  or  in  part)  the  net  number  of  shares  of
common stock determined according to a formula set forth in the Warrants.

Right as a Stockholder

Except as otherwise provided in the Warrants or by virtue of such holder’s ownership of shares of the Company’s common stock, the holders of the Warrants do not have the
rights or privileges of holders of common stock with respect to the shares of common stock underlying the Warrants, including any voting rights, until they exercise their
Warrants. The Warrants provide that holders have the right to participate in distributions or dividends paid on the Company’s common stock.

Fundamental Transaction

In  the  event  of  a  fundamental  transaction,  as  described  in  the  Warrants  and  generally  including  any  reorganization,  recapitalization  or  reclassification  of  the  Company’s
common stock, the sale, transfer or other disposition of all or substantially all of the Company’s properties or assets, the Company’s consolidation or merger with or into
another person, the acquisition of more than 50% of the Company’s outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting
power represented by the Company’s outstanding common stock, the holders of the Warrants will be entitled to receive upon exercise of the Warrants the kind and amount of
securities, cash or other property that the holders would have received had they exercised the Warrants immediately prior to such fundamental transaction. In addition, in the
event of a fundamental transaction which is approved by the Company’s board of directors, the holders of the warrants have the right to require the Company or a successor
entity  to  redeem  the  Warrants  for  cash  in  the  amount  of  the  Black  Scholes  value  of  the  unexercised  portion  of  the  Warrants  on  the  date  of  the  consummation  of  the
fundamental transaction. In the event of a fundamental transaction which is not approved by the Company’s board of directors, the holders of the Warrants have the right to
require the Company or a successor entity to redeem the Warrants in the amount of the Black Scholes value of the unexercised portion of the Warrants on the date of the
consummation of the fundamental transaction payable in the form of consideration paid to the holders of common stock in such fundamental transaction.

As of March 11, 2021, 3,057,395 Warrants have have been exercised for 2,626,418 shares of common stock and gross proceeds of approximately $14.3 million. These amounts
are exclusive of the Warrants exercised as part of the Warrant Exercise Inducement transaction discussed below.

Underwriter Warrant

On January 12, 2021, pursuant to the terms of the Underwriting Agreement, the Company issued to the Underwriter a warrant to purchase 806,932 shares of the Company’s
common stock (the “Underwriter Warrant”). The Underwriter Warrant is subject to substantially the same terms and conditions as the Warrants, provided that the exercise price
for the Underwriter Warrant is $8.125 per share. If the Underwriter exercises any additional portion of its over-allotment option, then the Company shall issue the Underwriter
an additional Underwriter Warrant exercisable for a number of shares of common stock equal to 5.0% of the number of shares of common stock issued in such over-allotment
exercise (including the shares of common stock issuable upon the exercise of any Warrants issued in connection therewith). In connection with the closing of the Underwriter's
partial exercise of its over-allotment option, on February 3, 2021, the Underwriter was issued an additional warrant to purchase 18,702 shares of common stock. As of March
11, 2020, no Underwriter Warrants have been exercised.

December 2020 Exchange Agreement Amendment

On  January  12,  2021,  in  connection  with  the  transactions  contemplated  by  the  December  2020  Exchange  Agreement,  the  Company  entered  into  an  Amendment  to  Senior
Secured Convertible Notes and Amendment to Warrant (the “January 2021 Amendment”) with the Deerfield Holders. The January 2021 Amendment modifies certain specified
terms of (i) the Facility Notes and (ii) the Deerfield Warrant to, among other things, exclude the transactions contemplated by the December 2020 Exchange Agreement and
issuance of securities pursuant to the Underwriting Agreement from the anti-dilution provisions of the Facility Notes and the Deerfield Warrant.

Series B-2 Preferred Stock

Pursuant  to  the  December  2020  Exchange  Agreement,  on  January  12,  2021,  the  Company  issued  to  the  Facility  Note  Holders  an  aggregate  of  31,476.98412  shares  of  its
Series B-2 Preferred Stock and warrants exercisable for an aggregate of 3,632,019 shares of the Company’s common stock (the “Exchange Warrants”).

The Series B-2 Preferred Stock is convertible into an aggregate of 4,842,690 shares of the Company’s common stock at a conversion price equal to $6.4999.

Amended and Restated Certificate of Designation of Preferences, Rights and Limitations of the Series B-2 Convertible Preferred Stock

On January 11, 2021, as a condition to closing of the transactions contemplated by the December 2020 Exchange Agreement, the Company filed an Amended and Restated
Certificate of Designation of Preferences, Rights and Limitations of Series B-2 Convertible Preferred Stock (the “Series B-2 Certificate of Designation”) with the Secretary of
State of the State Delaware, setting forth the preferences, rights and limitations of the Series B-2 Preferred Stock.

Immediately following, the closing of the Public Offering, pursuant to the terms of the December 2020 Exchange Agreement, the Company:

● Exchanged approximately $31.5 million (the "Exchange") of the outstanding principal and accrued interest on the Facility Notes for (i) the Series B-2 Preferred Stock

and (ii) the Exchange Warrants; and

● made a payment of approximately $30.3 million (the “Debt Payment”) in partial repayment of the remaining outstanding principal and accrued interest on the Facility

Notes.

Immediately following the completion of the Exchange and Debt Payment, the aggregate balance of principal and accrued interest remaining outstanding under the Facility
Notes was approximately $7.6 million.

Upon  the  closing  of  the  Exchange  and  related  Debt  Payment,  the  amendments  to  the  Facility  Agreement,  the  Notes  and  the  Investors’  Rights  Agreement,  dated  as  of
February  19,  2015,  by  and  among  the  Company,  Deerfield  and  the  other  parties  signatory  thereto,  contemplated  by  the  December  2020  Exchange  Agreement  that  were
conditional upon, among other things, the closing of the Public Offering, the filing of the Series B-2 Certificate of Designation and/or the approval for listing of the Company’s
common stock, including the shares issuable upon conversion of the Series B-2 Preferred Stock and exercise of the Exchange Warrants, on the Nasdaq Capital Market, became
effective on January 12, 2021.

As of March 11, 2021, all shares of Series B-2 Preferred Stock have have been converted into 4,842,699 shares of common stock. 

Listing on the Nasdaq Capital Market

On  January  7,  2021,  the  Company’s  common  stock  was  approved  for  listing  on  The  Nasdaq  Capital  Market.  The  Company’s  common  stock  began  trading  on  The  Nasdaq
Capital Market on January 8, 2021 under the ticker symbol “KMPH”.

Warrant Exercise Inducement Letters and Issuance of Warrants

On January 26, 2021, the Company entered into warrant exercise inducement offer letters (“Inducement Letters”) with certain holders of warrants issued in the Public Offering
discussed  above  (the  "Existing  Warrants")  (collectively,  the  “Exercising  Holders”)  pursuant  to  which  such  holders  agreed  to  exercise  for  cash  their  Existing  Warrants  to
purchase 6,620,358 shares of the Company’s common stock in exchange for the Company’s agreement to issue new warrants (the “Inducement Warrants”) on substantially the
same terms as the Existing Warrants, except as set forth in the following sentence, to purchase up to 7,944,430 shares of the Company’s common stock, which is equal to 120%
of the number of shares of the Company’s common stock issued upon exercise of the Existing Warrants. The purchase price of the Inducement Warrants was $0.125 per share
underlying  each  Inducement  Warrant,  and  the  Inducement  Warrants  have  an  exercise  price  of  $6.36  per  share.  The  Company  received  aggregate  gross  proceeds  of
approximately $44.0 million from the exercise of the Existing Warrants by the Exercising Holders and the sale of the Inducement Warrants. The Company engaged Roth as its
exclusive placement agent in connection with these transactions and paid Roth a fee equal to 6% of gross proceeds from the exercise of the Existing Warrants by the Exercising
Holders and the sale of the Inducement Warrants. As a result of this transaction the anti-dilution provisions contained with the Deerfield Warrant were triggered and the exercise
price of the Deerfield Warrant was reduced from $93.60 per share to $46.25 per share.

The  Company  also  agreed  to  file  a  registration  statement  covering  the  resale  of  the  shares  of  the  Company’s  common  stock  issued  or  issuable  upon  the  exercise  of  the
Inducement Warrants no later than 10 calendar days following the date of the Inducement Letters.

Inducement Warrant Terms

Duration and Exercise Price

The Inducement Warrants are exercisable from and after the date of their issuance and expire on the fifth anniversary of such date, at an exercise price per share of common
stock equal to $6.36 per share. The holder of an Inducement Warrant will not be deemed a holder of the underlying common stock until the Inducement Warrant is exercised.
No  fractional  shares  of  common  stock  will  be  issued  in  connection  with  the  exercise  of  the  Inducement  Warrants.  Instead,  for  any  such  fractional  share  that  would  have
otherwise been issued upon exercise of an Inducement Warrant, the Company will round such fraction up to the next whole share.

Exercisability

The Inducement Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to the Company a duly executed exercise notice, provided that
payment in full for the number of shares of the Company’s common stock purchased upon such exercise is delivered to the Company in accordance with the terms of the
Inducement Warrants (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Inducement
Warrant to the extent that the holder and its affiliates and any other person or entities with which such holder would constitute a Section 13(d) “group”  would own more than
4.99% (or, upon election by a holder prior to the issuance of its Inducement Warrants, 9.99%) of the Company’s outstanding common stock immediately after exercise.

Cashless Exercise

If,  at  the  time  a  holder  exercises  its  Inducement  Warrants,  a  registration  statement  registering  the  issuance  of  the  shares  of  common  stock  underlying  such  Inducement
Warrant under the Securities Act is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made
to the Company upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net
number of shares of common stock determined according to a formula set forth in the Inducement Warrants.

Right as a Stockholder

Except as otherwise provided in the Inducement Warrants or by virtue of such holder’s ownership of shares of the Company’s common stock, the holders of the Inducement
Warrants do not have the rights or privileges of holders of common stock with respect to the shares of common stock underlying the Inducement Warrants, including any
voting rights, until they exercise their Inducement Warrants. The Inducement Warrants provide that holders have the right to participate in distributions or dividends paid on
the Company’s common stock.

Fundamental Transaction

In  the  event  of  a  fundamental  transaction,  as  described  in  the  Inducement  Warrants  and  generally  including  any  reorganization,  recapitalization  or  reclassification  of  the
Company’s common stock, the sale, transfer or other disposition of all or substantially all of the Company’s properties or assets, the Company’s consolidation or merger with
or into another person, the acquisition of more than 50% of the Company’s outstanding common stock, or any person or group becoming the beneficial owner of 50% of the
voting power represented by the Company’s outstanding common stock, the holders of the Inducement Warrants will be entitled to receive upon exercise of the Inducement
Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Inducement Warrants immediately prior to
such fundamental transaction. In addition, in the event of a fundamental transaction which is approved by the Company’s board of directors, the holders of the Inducement
Warrants have the right to require the Company or a successor entity to redeem the Inducement Warrants for cash in the amount of the Black Scholes value of the unexercised
portion of the Inducement Warrants on the date of the consummation of the fundamental transaction. In the event of a fundamental transaction which is not approved by the
Company’s board of directors, the holders of the Inducement Warrants have the right to require the Company or a successor entity to redeem the Inducement Warrants in the
amount  of  the  Black  Scholes  value  of  the  unexercised  portion  of  the  Warrants  on  the  date  of  the  consummation  of  the  fundamental  transaction  payable  in  the  form  of
consideration paid to the holders of common stock in such fundamental transaction.

As of March 11, 2021, 1,676,921 Inducement Warrants have have been exercised for 1,676,921 shares of common stock and gross proceeds of approximately $10.7 million.

Payoff of Facility Agreement Notes and Termination of Facility Agreement

On  February  8,  2021,  the  Company  entered  into  a  payoff  letter  with  the  Facility  Agreement  Note  Holders,  pursuant  to  which  the  Company  agreed  to  pay  off  and  thereby
terminate the Facility Agreement.

Pursuant to the payoff letter, the Company paid a total of $8.0 million to the Facility Agreement Note Holders, representing the principal balance, accrued interest outstanding
and a prepayment fee in repayment of the Company’s outstanding obligations under the Facility Agreement.

Pursuant to the payoff letter, all outstanding indebtedness and obligations of the Company owing to the Facility Agreement Note Holders under the Facility Agreement have
been paid in full. The Facility Agreement and the notes thereunder, as well as the security interests in the assets of the Company securing the Facility Agreement and note
obligations, have been terminated. The Facility Agreement Note Holders will retain the warrants previously issued to them by the Company. 

FDA Approval of the AZSTARYS NDA

On March 2, 2021, the Company announced that the FDA approved the NDA for AZSTARYS™ (serdexmethylphenidate and dexmethylphenidate capsules, for oral use, CII), a
once-daily  product  for  the  treatment  of  ADHD  in  patients  age  six  years  and  older.  As  a  result  of  the  FDA’s  approval  of  the  AZSTARYS  NDA,  the  Company  has  earned  a
regulatory milestone payment  as provided under the KP415 License Agreement.

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

Exhibit 4.8

KemPharm, Inc. (“we,” “our,” or “us”) has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended, our common stock, par
value $0.0001 per share, or common stock. The following description of our capital stock is a summary and does not purport to be complete. It is qualified in its entirety by, and
should be read in conjunction with, our amended and restated certificate of incorporation, amended and restated bylaws and applicable Delaware law.

General

Under our amended and restated certificate of incorporation we are authorized to issue up to 250,000,000 shares of common stock and 10,000,000 shares of preferred stock,
$0.0001  par  value  per  share,  of  which  9,578  shares  have  been  designated  Series  A  preferred  stock,  or  the  Series  A  Preferred  Stock,  1,576  shares  have  been  designated  as
Series B-1 preferred stock, or the Series B-1 Preferred Stock, and 31,480 shares have been designated as Series B-2 preferred stock, or the Series B-2 Preferred Stock (and
together with the Series B-1 Preferred Stock, the Series B Preferred Stock). As of March 10, 2021, we had outstanding (i) 28,376,321 shares of common stock, and (ii) no
shares of Series B-2 Preferred Stock. Our board of directors may establish the rights and preferences of the undesignated preferred stock from time to time.

Common Stock 

Voting Rights

Each holder of our 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 our
amended and restated certificate of incorporation and amended and restated bylaws, our stockholders do not have cumulative voting rights. Because of this, the holders of a
majority of the shares of our 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 our 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 our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to
stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then-outstanding shares of
preferred stock.

Rights and Preferences

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

Preferred Stock

Pursuant to our amended and restated certificate of incorporation, our board of directors has the authority, without further action by the stockholders (unless such stockholder
action is required by applicable law or stock exchange listing rules), to designate and issue up to 10,000,000 shares of preferred stock in one or more series, to establish from
time to time the number of shares to be included in each such series, to fix the designations, powers, preferences, privileges and relative participating, optional or special rights
and the qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all
of which may be greater than the rights of our common stock, and to increase or decrease the number of shares of any such series, but not below the number of shares of such
series then outstanding. Our board of directors, without stockholder approval, can issue preferred stock with voting, conversion or other rights that could adversely affect the
voting power and other rights of the holders of our common stock. Preferred stock could be issued quickly with terms designed to delay or prevent a change in control of our
company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock
and  may  adversely  affect  the  voting  power  of  holders  of  our  common  stock  and  reduce  the  likelihood  that  our  common  stockholders  will  receive  dividend  payments  and
payments upon liquidation.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our board of directors will fix the designations, voting powers, preferences and rights, as well as the qualifications, limitations or restrictions, of the preferred stock of each
series that we offer in the certificate of designation relating to that series.

The Delaware General Corporation Law, the law governing corporations in the state of our incorporation, provides that the holders of preferred stock will have the right to vote
separately as a class (or, in some cases, as a series) on an amendment to our certificate of incorporation if the amendment would change the par value or, unless the certificate of
incorporation provided otherwise, the number of authorized shares of the class or change the powers, preferences or special rights of the class or series so as to adversely affect
the class or series, as the case may be. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation.

As of March 10, 2021, we have designated an aggregate of 42,634 shares of preferred stock, of which 9,578 are designated Series A Preferred Stock, 1,576 are designated
Series B-1 Preferred Stock and 31,480 are designated Series B-2 Preferred Stock.

Amended and Restated Series B-2 Certificate of Designation

On January 11, 2021, we filed an Amended and Restated Series B-2 Certificate of Designation with the Secretary of State of the State Delaware, setting forth the preferences,
rights and limitations of the Series B-2 Preferred Stock. As of March 10, 2021, we had designated 31,480 shares of preferred stock as Series B-2 Preferred Stock, of which no
shares were outstanding.

Each share of Series B-2 Preferred Stock has an aggregate stated value of $1,000 and is convertible into shares of our common stock at a per share price equal to $6.4999
(subject to adjustment to reflect stock splits and similar events).

The Series B-2 Preferred Stock are convertible at any time on or after the PDUFA Date (as defined in the Amended and Restated Series B-2 Certificate of Designation) at the
option of the holders thereof; provided that the holders thereof will be prohibited from converting shares of Series B-2 Preferred Stock into shares our common stock if, as a
result of such conversion, such holders (together with certain affiliates and “group” members of such holders) would beneficially own more than 4.985% of the total number of
shares of our common stock then issued and outstanding. The Series B-2 Preferred Stock are not be redeemable. In the event of our liquidation, dissolution or winding up or our
change in control, the holders of Series B-2 Preferred Stock will receive, prior to any distribution or payment on our common stock, an amount equal to the greater of (i) $1,000
per share (in the case of a change in control, transaction consideration with such value), or (ii) the amount (in the case of a change in control, in the form of the transaction
consideration) per share each such holder would have been entitled to receive if every share of Series B-2 Preferred Stock had been converted into common stock immediately
prior to such event, in each case, plus any declared but unpaid dividends thereon. With respect to rights upon liquidation, the Series B-2 Preferred Stock rank senior to our
common stock, on parity with any Parity Securities (as defined in the Amended and Restated Series B-2 Certificate of Designation) and junior to any Senior Securities (as
defined  in  the  Amended  and  Restated  Series  B-2  Certificate  of  Designation)  and  existing  and  future  indebtedness.  Except  as  otherwise  required  by  law  (or  with  respect  to
approval of certain actions involving our organizational documents that adversely affect the holders of Series B-2 Preferred Stock and other specified matters regarding the
rights, preferences and privileges of the Series B-2 Preferred Stock), the Series B-2 Preferred Stock do not have voting rights. The Series B-2 Preferred Stock are not be subject
to any price-based anti-dilution protections and do not provide for any accruing dividends, but do provide that holders of Series B-2 Preferred Stock will participate in any
dividends  on  our  common  stock  on  an  as-converted  basis  (without  giving  effect  to  the  limitation  on  conversion  described  above).  The  Amended  and  Restated  Series  B-2
Certificate of Designation also provides for partial liquidated damages in the event that we fail to timely convert shares of Series B-2 Preferred Stock into common stock in
accordance with the Amended and Restated Series B-2 Certificate of Designation.

Outstanding Warrants

As of March 10, 2021, we had outstanding warrants to purchase up to 9,645,193 shares of our common stock at a weighted average exercise price of $7.142 per share and
which expire between October 24, 2023 and January 26, 2026. The warrants include a net exercise provision and contain provisions for the adjustment of the exercise price and
the number of shares issuable upon the exercise of each warrant in the event of certain stock dividends, stock splits, reorganizations, reclassifications and consolidations. We
have also granted registration rights to Deerfield Private Design Fund III, L.P., or Deerfield, as more fully described below under “—Registration Rights.”

In June 2014, in connection with our entering into a facility agreement, we issued to Deerfield a warrant, or the Deerfield Warrant, to purchase 14,423,076 shares of Series D
redeemable  convertible  preferred  stock  at  an  exercise  price  of  $0.78  per  share,  which  is  exercisable  until  June  2,  2024.  Upon  completion  of  our  initial  public  offering,  the
Deerfield Warrant automatically converted into a warrant to purchase 120,192 shares of our common stock at an exercise price of $93.60 per share. According to the terms of
the Deerfield Warrant, in no event may Deerfield exercise this warrant if such exercise would result in Deerfield beneficially owning more than 4.985% of the then issued and
outstanding shares of our common stock. This exercise limitation may not be waived and any purported exercise that is inconsistent with this exercise limitation is null and
void.  This  exercise  limitation  will  not  apply  to  any  exercise  made  immediately  prior  to  a  change  of  control  transaction.  If  Deerfield  is  only  able  to  exercise  the  Deerfield
Warrant for a limited number of shares due to this exercise limitation, the Deerfield Warrant could subsequently become exercisable to purchase the remainder of the shares as a
result of a variety of events. This could occur, for example, if we issue more shares or Deerfield sells some of its existing shares. The Deerfield Warrant includes a net exercise
provision  and  contains  provisions  for  the  adjustment  of  the  exercise  price  and  the  number  of  shares  issuable  upon  the  exercise  of  the  warrant  in  the  event  of  certain  stock
dividends,  stock  splits,  recapitalizations,  reclassifications  and  consolidations.  Under  the  Deerfield  Warrant,  Deerfield  also  has  the  right  to  demand  upon  the  occurrence  of
specified events, including a merger, asset sale or other change of control transaction, that we redeem the Deerfield Warrant for a cash amount equal to the Black-Scholes value
of the portion of the Deerfield Warrant to be redeemed. If Deerfield chooses not to redeem the Deerfield Warrant upon the occurrence of such an event, we may not enter into
any such transaction unless our successor entity assumes in writing all our obligations under both the Deerfield Warrant and the Deerfield facility and provides Deerfield with
certain registration rights.

 
 
 
 
 
 
 
 
 
 
 
 
 
The Deerfield Warrant includes certain exercise price protection provisions pursuant to which the exercise price of the Deerfield Warrant will be adjusted downward on a broad-
based weighted average basis if we issue or sell any shares of common stock, convertible securities, warrants or options, at a sale or exercise price per share less than the greater
of the Deerfield Warrant’s exercise price or the closing sale price of our common stock on our principal market or exchange on the last trading date immediately prior to such
issuance or, in the case of a firm commitment underwritten offering, on the date of execution of the underwriting agreement between us and the underwriters for such offering.
The sale price for purposes of this adjustment is measured after giving effect to any underwriting discounts and commissions. This exercise price adjustment does not apply to
certain specified sales and in any offering deemed by the Securities and Exchange Commission, or the SEC, to constitute an “at the market offering” as defined in Rule 415 of
the Securities Act  of 1933, or the Securities Act, of our common stock, the exercise price of the Deerfield Warrant will be adjusted downward pursuant to this anti-dilution
adjustment only if such sales are made at a price less than $93.60 per share. On January 26, 2021, we entered into a Warrant Inducement transaction which triggered these
exercise price protection provision and the exercise price of the Deerfield Warrant was reduced from $93.60 per share to $46.25 per share.

In January 2021, and in February 2021 in accordance with the underwriter's partial exercise of their over-allotment option, we issued the Underwritten Warrants and additional
substantially similar warrants to purchase shares of our common stock pursuant to an underwriting agreement and the December 2020 Exchange Agreement (as defined below),
or, collectively with the Underwritten Warrants and the Warrants, the January 2021 Warrants.

The January 2021 Warrants are exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full
for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise). A holder (together with its affiliates) may not exercise
any portion of a January 2021 Warrant to the extent that the holder would own more than 4.99% of our outstanding common stock immediately after exercise, except that upon
at least 61 days’ prior notice from the holder of a January 2021 Warrant issued under the underwriting agreement, the holder may increase the amount of beneficial ownership
of outstanding stock after exercising the holder’s January 2021 Warrant up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect
to the exercise, as such percentage ownership is determined in accordance with the terms of the January 2021 Warrant and Delaware law. Purchasers of January 2021 Warrants
under the underwriting agreement may have also elected prior to the issuance of the January 2021 Warrants to have the initial exercise limitation set at 9.99% of our outstanding
common stock.

If,  at  the  time  a  holder  exercises  its  January  2021  Warrants,  a  registration  statement  registering  the  issuance  of  the  shares  of  common  stock  underlying  such  January  2021
Warrant under the Securities Act is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to
us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares
of common stock determined according to a formula set forth in the January 2021 Warrants.

In  the  event  of  a  fundamental  transaction,  as  described  in  the  January  2021  Warrants  and  generally  including  any  reorganization,  recapitalization  or  reclassification  of  our
common  stock,  the  sale,  transfer  or  other  disposition  of  all  or  substantially  all  of  our  properties  or  assets,  a  consolidation  or  merger  of  us  with  or  into  another  person,  the
acquisition  of  more  than  50%  of  our  outstanding  common  stock,  or  any  person  or  group  becoming  the  beneficial  owner  of  50%  of  the  voting  power  represented  by  our
outstanding common stock, the holders of the January 2021 Warrants will be entitled to receive upon exercise of the January 2021 Warrants the kind and amount of securities,
cash or other property that the holders would have received had they exercised the January 2021 Warrants immediately prior to such fundamental transaction. In addition, in the
event of a fundamental transaction which is approved by our board of directors, the holders of the January 2021 Warrants have the right to that we or a successor entity to
redeem the January 2021 Warrants for cash in the amount of the Black Scholes value of the unexercised portion of the January 2021 Warrants on the date of the consummation
of the fundamental transaction. In the event of a fundamental transaction which is not approved by our board of directors, the holders of the January 2021 Warrants have the
right to require that we or a successor entity to redeem the January 2021 Warrants in the amount of the Black Scholes value of the unexercised portion of the January 2021
Warrants on the date of the consummation of the fundamental transaction payable in the form of consideration paid to the holders of our common stock in such fundamental
transaction.

 
 
 
 
 
 
 
 
Registration Rights

Investors’ Rights Agreement

We and the holders of shares of our common stock issued upon the conversion or reclassification of our redeemable convertible preferred stock have entered into an investors’
rights agreement. The registration rights provisions of this agreement expired as to all holders of our capital stock, other than Deerfield, on the second anniversary of our initial
public offering. The registration rights provisions of our investors’ rights agreement currently provide Deerfield with the registration rights described in more detail below.

Demand Registration Rights

Deerfield  has  the  right  to  demand  that  we  file  a  Form  S-1  registration  statement,  as  long  as  the  anticipated  aggregate  offering  price,  net  of  underwriting  discounts  and
commissions, would exceed $15.0 million. These registration rights are subject to specified conditions and limitations, including the right of the underwriters, if any, to limit the
number of shares included in any such registration under specified circumstances. Upon such a request, we are required to effect the registration as soon as reasonably possible.

Piggyback Registration Rights

If we propose to register any of our securities under the Securities Act either for our own account or for the account of other stockholders, Deerfield will be entitled to include
its shares of our common stock in the registration statement. These piggyback registration rights are subject to specified conditions and limitations, including the right of the
underwriters to limit the number of shares included in any such registration under specified circumstances.

Registration on Form S-3

Deerfield is entitled, upon its written request, to have such shares registered by us on a Form S-3 registration statement at our expense, subject to other specified conditions and
limitations.

Expenses of Registration

We will pay all expenses relating to any demand, piggyback or Form S-3 registration, other than underwriting discounts and commissions, subject to specified conditions and
limitations.

Termination of Registration Rights

The registration rights granted under the investors’ rights agreement terminated as to all the holders of our capital stock, other than Deerfield, on the two-year anniversary of our
initial public offering. These registration rights will terminate as to Deerfield upon the earliest to occur of (i) written consent of Deerfield, (ii) such time that the Deerfield
Warrant has been exercised in full and Rule 144 or another similar exemption under the Securities Act is available for the sale of all shares of our capital stock held by Deerfield
without limitation during a three-month period without registration or (iii) six-months following the expiration of the Deerfield Warrant.

Anti-Takeover Provisions

Section 203 of the Delaware General Corporation Law

We  are  subject  to  Section  203  of  the  Delaware  General  Corporation  Law,  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

Our amended and restated certificate of incorporation provides for our 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  our  stockholders,  with  the  other  classes  continuing  for  the  remainder  of  their  respective  three-year  terms.  Because  our
stockholders do not have cumulative voting rights, stockholders holding a majority of the shares of our common stock outstanding will be able to elect all of our directors. Our
amended and restated certificate of incorporation and our amended and restated bylaws also provide that directors may be removed by the stockholders only for cause upon the
vote of 66 2/3% or more of our 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  of  directors,  only  be  filled  by  a
majority vote of the directors then serving on the board of directors, even though less than a quorum.

Our amended and restated certificate of incorporation and amended and restated bylaws also provide that all stockholder actions must be effected at a duly called meeting of
stockholders and eliminates the right of stockholders to act by written consent without a meeting. Our amended and restated bylaws also provide that only our 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.

Our  amended  and  restated  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.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that the stockholders cannot amend many of the provisions described above
except by a vote of 66 2/3% or more of our outstanding common stock.

The combination of these provisions make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by
replacing  our  board  of  directors.  Since  our  board  of  directors  has  the  power  to  retain  and  discharge  our  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 our board of directors to
issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change our control.

These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage coercive takeover
practices and inadequate takeover bids. These provisions are also designed to reduce our 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 our shares and may have the effect of delaying changes in our
control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of our stock that could result from actual or rumored takeover
attempts. We believe that the benefits of these provisions, including increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited
proposal to acquire or restructure our company, outweigh the disadvantages of discouraging takeover proposals, because negotiation of takeover proposals could result in an
improvement of their terms.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Choice of Forum

Our amended and restated bylaws provide that (1) unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if
and only if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any state court located within the State of Delaware or, if and only if all such state
courts  lack  subject  matter  jurisdiction,  the  federal  district  court  for  the  District  of  Delaware)  shall  be  the  sole  and  exclusive  forum  for  the  following  types  of  actions  or
proceedings under Delaware statutory or common law: (A) any derivative action or proceeding brought on behalf of us; (B) any action or proceeding asserting a claim of breach
of a fiduciary duty owed by any current or former director, officer or other employee of us, to us or our stockholders; (C) any action or proceeding asserting a claim against us
any  current  or  former  director,  officer  or  other  employee  of  us,  arising  out  of  or  pursuant  to  any  provision  of  the  Delaware  General  Corporation  Law,  or  the  DGCL,  our
amended and restated certificate of incorporation or our amended and restated bylaws (as each may be amended from time to time); (D) any action or proceeding to interpret,
apply, enforce or determine the validity of our amended and restated certificate of incorporation or our amended and restated bylaws (including any right, obligation, or remedy
thereunder);  (E)  any  action  or  proceeding  as  to  which  the  DGCL  confers  jurisdiction  to  the  Court  of  Chancery  of  the  State  of  Delaware;  and  (F)  any  action  or  proceeding
asserting a claim against us or any director, officer or other employee of us, governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and
subject to the court’s having personal jurisdiction over the indispensable parties named as defendants, provided that this provision shall not apply to suits brought to enforce a
duty or liability created by the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction; (2) unless we consent in writing to
the  selection  of  an  alternative  forum,  to  the  fullest  extent  permitted  by  law,  the  federal  district  courts  of  the  United  States  of  America  shall  be  the  exclusive  forum  for  the
resolution of any complaint asserting a cause of action arising under the Securities Act; and (3) any person or entity holding, owning or otherwise acquiring any interest in any
of our securities shall be deemed to have notice of and consented to the provisions of our amended and restated bylaws.

Company shall be entitled to the following compensation for service on the Board and its committees:

Cash Compensation

Cash compensation shall be paid in the following annual amounts. Payments shall be made in quarterly installments in arrears on the last day of each calendar
quarter  in  which  service  occurred,  and  shall  be  prorated  as  appropriated  for  a  director  who  does  not  serve  for  the  full  quarter.    For  the  avoidance  of  doubt,  the  cash
compensation set forth below shall apply for the entire quarter in which this policy is adopted by the Board.

1. Annual Board Service Retainer:

a. All non-employee directors: $35,000
b. Chairman of the Board, if not an employee, or lead independent director, if any (in addition to the retainer for all non-employee directors): $15,000

2. Annual Committee Member Service Retainer:

a. Member of the Audit Committee: $7,500
b. Member of the Compensation Committee: $5,000
c. Member of the Nominating and Corporate Governance Committee: $5,000

b. Chairman of the Compensation Committee: $10,000
c. Chairman of the Nominating and Corporate Governance Committee: $7,500

Equity Compensation

The equity compensation set forth below will be granted under the Company’s 2014 Equity Incentive Plan, or, as the case may be, any successor equity incentive
plan approved by the stockholders of the Company (the “Plan”). All stock options granted under this policy will be nonqualified stock options using the Company’s standard
form of Nonqualified Stock Option Agreement under the Plan, with an exercise price per share equal to the last reported sale price of the Company’s common stock on the
NASDAQ Capital Market on the date of grant or, if such grant date is not a trading date, on the last trading date prior to the grant date, and with a term of ten years from the
date of grant (subject to earlier termination in connection with a termination of service as provided in the Plan).

Annual Grant: On the date of each annual stockholders meeting of the Company, each director who continues to serve as a non-employee member of the Board
following such stockholders meeting will be automatically, and without further action by the Board or the Compensation Committee of the Board, be granted a stock option for
15,000 shares of common stock. The stock options will vest and become exercisable in full on the earlier of (1) the first anniversary of the grant date, (2) the day before the first
annual  stockholders  meeting  occurring  after  the  grant  date  or  (3)  immediately  prior  to  a  “Change  in  Control”  as  defined  in  the  Plan,  subject  in  each  case  to  the  director’s
continued service on such vesting date.  For the avoidance of doubt, the common stock share number set forth above shall be on a post-reverse stock split basis (giving effect to
the reverse stock split adopted by the Company in December 2020).
