ITEM 1. BUSINESS

Business

PART I

Abeona Therapeutics Inc., a Delaware corporation (together with our subsidiaries, “we,” “our,” “Abeona” or the “Company”), is a clinical-stage biopharmaceutical company
developing cell and gene therapies for life-threatening diseases. Our lead clinical program is for prademagene zamikeracel (“pz-cel”), our investigational autologous, COL7A1
gene-corrected epidermal sheets currently in development for recessive dystrophic epidermolysis bullosa (“RDEB”). Pz-cel has been granted Orphan Drug and Rare Pediatric
Disease (“RPD”) designations by the U.S. Food and Drug Administration (“FDA”) and Orphan Drug Designation by the European Medicines Agency (“EMA”).

We plan to continue development of adeno-associated virus (“AAV”) based gene therapies designed to treat ophthalmic diseases with high unmet medical need using the novel
AIM™ capsid platform that we have exclusively licensed from the University of North Carolina at Chapel Hill (“UNC”), and internal AAV vector research programs. Abeona’s
novel, next-generation AAV capsids are being evaluated to improve tropism profiles for a variety of devastating diseases.

Our Mission and Strategy

Abeona is a fully-integrated cell and gene therapy company featuring research and clinical development programs, in-house manufacturing facilities, and scientific and clinical
leadership. Our mission is to create, develop, manufacture, and deliver cell and gene therapies to transform the lives of people impacted by life-threatening diseases. In 2023,
we continued to make progress toward fulfilling our goal of harnessing the promise of genetic medicine and redefining the standard of care through cell and gene therapies. In
September 2023, we submitted a Biologics License Application (“BLA”) for pz-cel to the FDA. In November 2023, the FDA accepted and granted priority review for our BLA
for pz-cel. Under the Prescription Drug User Fee Act (“PDUFA”), the FDA has set a target action date of May 25, 2024.

We partner with leading academic researchers, patient advocacy organizations, caregivers and other biotechnology companies to develop therapies that address the underlying
cause of a broad spectrum of rare genetic diseases for which no effective treatment options exist today.

Our strategy consists of:

Advancing and Commercializing our Late-Stage Clinical Cell and Gene Therapy Programs with a Focus on Life-Threatening Diseases.

Through our cell and gene therapy expertise in research and development, we believe we are positioned to introduce efficacious and safe therapeutics to transform the
standard of care in devastating diseases and establish our leadership position in the field. We intend to commercialize our assets either by ourselves or through strategic
partnerships, subject to FDA approval.

Developing Novel In-Vivo Gene Therapies Using AIM™ Capsid Technology.

We are researching and developing AAV-based gene therapy using our novel capsids developed from the AIM™ Capsid Technology Platform and additional Company-
invented AAV  capsids. We  plan  to  continue  to  develop  our  chimeric AAV  capsids  capable  of  improved  tissue  targeting  for  various  indications  and  potentially  evading
immunity to wild-type AAV vectors.

Leveraging our Leadership Position in Commercial-Scale Cell and Gene Therapy Manufacturing.

We established current Good Manufacturing Practice (“cGMP”), clinical-scale manufacturing capabilities for engineered cell therapy and AAV-based gene therapies in our
state-of-the-art  Cleveland,  Ohio  facility.  We  believe  that  our  platform  provides  us  with  distinct  advantages,  including  flexibility,  scale,  reliability,  and  the  potential  for
reduced development risk, reduced cost, and faster times to market. We have focused on establishing internal Chemistry, Manufacturing and Controls (“CMC”) capabilities
that drive value for our organization through process development, assay development and manufacturing. We have also deployed robust quality systems governing all
aspects of product lifecycle from preclinical through commercial stage.

Establishing Additional Cell and Gene Therapy Franchises and Adjacencies through In-Licensing and Strategic Partnerships.

We  seek  to  be  the  partner  of  choice  in  cell  and  gene  therapy  treatments  and  have  closely  collaborated  with  leading  academic  institutions,  key  opinion  leaders,  patient
foundations, and industry partners to accelerate research and development, understand the needs of patients and their families, and generate novel intellectual property.

Maintaining and Growing our IP Portfolio.

We  seek  patent  rights  for  various  aspects  of  our  programs,  including  vector  engineering  and  construct  design,  our  production  process,  and  all  features  of  our  clinical
products including composition of matter and method of administration and delivery. We expect to continue to expand our intellectual property portfolio by aggressively
seeking patent rights for promising aspects of our product engine and product candidates.

Developing Next-Generation Cell and Gene Therapy

Pz-cel for the Treatment of RDEB

Disease Overview

RDEB belongs to a broad group of genetic skin disorders known as epidermolysis bullosa. Patients with RDEB have a defect in the COL7A1 gene, resulting in the inability to
produce Type VII collagen, which plays a vital role in skin functioning by anchoring the skin’s dermal and epidermal layers to one another.

As a result of the genetic defect, RDEB patients have fragile skin, which can easily damage to produce open and blistering wounds, disfiguring scars throughout the body, fused
fingers and toes, limits in range of motion at joints (e.g., arms and legs), corneal abrasions, and an abnormal narrowing of the esophagus. Long-term RDEB patients can suffer
from anemia, are at high risk of developing aggressive squamous cell carcinomas, infections, and premature death. The most severe patients are approximately 20 times more
likely to die by 30 years of age than the general population.

Similar to other rare diseases, the incidence and prevalence of RDEB are not well defined. Incidence of 0.2 to 3.05 per million births and prevalence of 0.14 to 1.35 per million
people  have  been  observed  across  different  geographies,  primarily  estimated  by  limited  population  analyses  of  clinical  databases  or  registries  (Eichstadt  et  al.;  Clinical,
Cosmetic and Investigational Dermatology, 2019). Using genetic modeling of COL7A1 variants, which is believed to cause RDEB, Stanford University estimated the incidence
of RDEB to be approximately 63 per million births, and prevalence could be up to 3,850 patients in the U.S., whose wounds may benefit from COL7A1-mediated treatments
such as pz-cel.

RDEB patients have an active disease with the majority of the wounds typically > 20 cm2 (Stanford University; Solis, D., et al., 2017). In 2020, a survey of RDEB patients
reported that approximately 60% have active wounds covering greater than 30% of their bodies (Bruckner et al.; Orphanet Journal of Rare Diseases, 2020). Wounds covering
up to approximately 80% of body surface area have been recorded in some EB patients (Hirsch et al.; Nature Research, 2017).

4

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In our VIITALTM phase 3 and phase 1/2a clinical trials, pz-cel was applied as a one-time surgical procedure onto RDEB wounds and has shown up to 8 years of durable wound
healing and associated pain reduction even in the toughest-to-treat in RDEB wounds. Patients evaluated in the VIITALTM phase 3 trial had large wounds (> 20cm2) and, on
average, had wounds remained open for 6.2 years, and in some cases up to 21 years, prior to pz-cel treatment. Most RDEB patients have large and chronic wounds that carry
the highest burden, including the need for frequent dressing changes, pain, pruritus, risk of infection, and developing skin cancer.

Current Management of RDEB

Standard of care in RDEB wound management currently consists of time and labor-intensive supportive care to limit contamination and infection, and reduction in mechanical
forces that produce new blisters. Care usually includes treatment of new blisters by lancing and draining. Wounds are then dressed with a non-adherent material, covered with
padding for stability and protection, and secured with an elastic wrap for integrity. In a cost analysis conducted by Debra of America, based on 3,274 patient’s health insurance
claims from private insurance the annual cost of dystrophic epidermolysis bullosa (DEB) was identified to be 465% greater than the annual cost to the healthcare system from
all people. The cost of wound care supplies could be as high as $996,000 per year.

RDEB patients also have periodic surgeries to relieve disease related issues such as narrowing of their esophagus, fusing of fingers, and corneal abrasions.

In  2023,  Vyjuvek®  and  Filsuvez®  were  approved  by  the  FDA  for  treatment  of  wounds  associated  with  DEB  and  wounds  associated  with  Junctional  (JEB)  and  DEB,
respectively. The introduction of these drugs may further increase the total cost of care.

Program Status

Pz-cel is our investigational autologous epidermal sheets in which a functioning COL7A1 gene is inserted into a patient’s own skin cells (keratinocytes) using a retrovirus. The
keratinocytes are then grown into credit card sized sheets and surgically applied to the patient to restore Type VII collagen expression and skin function.

Results from a completed Phase 1/2a study that enrolled seven patients with large and chronic RDEB wounds at Stanford University showed that pz-cel was well-tolerated and
resulted in significant and durable wound healing (Siprashvili, Z., et al., 2016), with up to eight years of follow-up (So. Y, Nazaraoff, et al., Orphanet Journal Rare Disease
2022). To date, there have been no reported serious adverse events.

In November 2022, we announced positive topline data from our VIITAL™ study. The pivotal phase 3 VIITAL™ study evaluated the efficacy, safety, and tolerability of pz-cel
in 43 large chronic wound pairs in 11 subjects with RDEB. The large chronic wounds randomized and treated in VIITAL™ measured greater than 20 cm2 of surface area and
had remained open for a minimum of six months and a maximum of 21 years (mean 6.2 years). The co-primary endpoints of the study were: (1) the proportion of RDEB wound
sites  with  greater  than  or  equal  to  50%  healing  from  baseline,  comparing  randomized  treated  with  matched  untreated  (control)  wound  sites  at  the  six-month  timepoint,  as
determined by direct investigator assessment; and (2) pain reduction associated with wound dressing change assessed by the mean differences in scores of the Wong-Baker
FACES® Pain Rating Scale between randomized treated and matched untreated (control) wounds at the six-month timepoint.

The VIITAL™ study met its two co-primary efficacy endpoints demonstrating statistically significant, clinically meaningful improvements in wound healing and pain reduction
in  large  chronic  RDEB  wounds.  Pz-cel  was  shown  to  be  well-tolerated  with  no  serious  treatment-related  adverse  events  observed,  consistent  with  past  clinical  experience.
There were no deaths or instances of positive replication-competent retrovirus results, and no systemic immunologic responses were reported during the study, as well as no
squamous  cell  carcinoma  at  treatment  sites  after  application  of  pz-cel.  Two  subjects  reported  at  least  one  serious  adverse  event  unrelated  to  pz-cel.  Four  subjects  reported
related treatment emergent adverse events, including procedural pain, muscle spasms and pruritis. Infections unrelated to pz-cel were observed in eight patients.

5

 
 
 
 
 
 
 
 
 
 
 
 
In September 2023, we submitted a BLA for pz-cel to the FDA. In November 2023, the FDA accepted for filing and granted priority review for our BLA for pz-cel. Under the
PDUFA, the FDA has set a target action date of May 25, 2024. Pz-cel has been granted Regenerative Medicine Advanced Therapy (“RMAT”), Breakthrough Therapy, Orphan
Drug and RPD designations by the by the FDA as well as Orphan Drug designation by the EMA.

Among the potential benefits of Orphan Drug designation are a potential seven years of market exclusivity following FDA approval, potentially preventing FDA approval of
another  product  deemed  to  be  the  same  as  the  approved  product  for  the  same  indication,  waiver  of  application  fees,  and  tax  credits  for  qualified  clinical  testing  expenses
conducted after orphan designation is received. A sponsor who receives an approval for a BLA with RPD designation may qualify for a Priority Review Voucher (“PRV”),
subject to final determination by the FDA. A PRV may be used to receive expedited review of a subsequent marketing application for a different product or sold to another
company.

We have continued to prepare our cGMP commercial facility in Cleveland for manufacturing pz-cel to support our planned BLA filing. Pz-cel study drug product for all our
VIITAL™ study participants has been manufactured at our Cleveland facility.

ABO-503 for the treatment of X-linked Retinoschisis (“XLRS”).

Disease Overview and Program Overview

XLRS is a rare, monogenic retinal disease that results in the irreversible loss of photoreceptor cells and severe visual impairment. XLRS is caused by mutations in the RS1
protein, which is normally secreted by retinal photoreceptors and bipolar neurons and functions to mediate cell-cell adhesion. XLRS is characterized by abnormal splitting of
the layers of the retina, resulting in poor visual acuity, which can progress to legal blindness. The incidence of XLRS is estimated to be between 1 in 5,000 and 1 in 20,000 in
males, with an estimated prevalence of 35,000 in the United States and Europe combined. There are currently no disease modifying therapies approved for XLRS, but because
the genetics of the disease are well understood, early intervention via gene therapy has significant potential to reverse or stabilize disease progression at early stages and prevent
vision loss.

ABO-503,  composed  of  a  functional  human  RS1  packaged  in  the  novel AIM™  capsid AAV204,  has  shown  preclinical  efficacy  following  delivery  to  the  retina  in  a  mouse
model of XLRS. Preclinical studies have demonstrated robust RS1 expression in the retina, improved cone photoreceptor density and overall photoreceptor cell survival, as
well as a restoration of outer retina architecture. Results of these studies were presented at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting in May
2023. A pre-IND meeting for ABO-503 was conducted with the FDA in April 2023 and provided Abeona with comprehensive feedback to support a future IND submission.

ABO-504 for the Treatment of Stargardt Disease

Disease Overview and Program Overview

Autosomal recessive Stargardt disease, the most common form of juvenile macular degeneration with estimated incidence of 1 in 8,000 to 10,000 people, causes vision loss in
children  and  young  adults.  The  most  common  form  of  Stargardt  disease  is  caused  by  mutations  in  the  ABCA4  gene,  which  prevent  removal  of  toxic  compounds  from
photoreceptor cells that results in photoreceptor cell death and progressive vision loss. There are currently no FDA approved treatments available, and to date, development of
investigational gene modifying therapies has remained challenging in part due to the large size of the ABCA4 gene, which exceeds the encapsidation capacity of a single AAV
vector.

Abeona’s internal research and development team developed ABO-504, which is designed to efficiently reconstitute the full-length ABCA4 gene by implementing a dual AAV
vector strategy using the Cre-LoxP recombinase system. Abeona previously reported preclinical data demonstrating the ability of the dual AAV vector system to produce full
length ABCA4 protein in cell culture. Recent proof-of-concept studies, presented at the 2023 ASGCT Annual Meeting, have extended these findings by showing expression of
ABCA4 mRNA and full-length ABCA4 protein in the retina of subretinally dosed abca4-/- knockout mice, at levels similar to endogenous ABCA4 in wild-type animals. A pre-
IND meeting for ABO-504 was conducted with the FDA in June 2023 and provided Abeona with comprehensive feedback to support a future IND submission.

ABO-505 for the Treatment of Autosomal Dominant Optic Atrophy (“ADOA”)

Disease Overview and Program Overview

ADOA, a form of hereditary vision loss associated with retinal ganglion cell (“RGC”) death, is predominantly caused by mutations in the Opa1 gene. Opa1, a dynamin-related
GTPase, acts to stabilize the inner mitochondrial membrane and acts in mitochondrial fusion and inner membrane remodeling. Mutant phenotypes present with a progressive
loss of RGCs that results in optic nerve degeneration and legal blindness with a loss of visual acuity, optic disc pallor, and color vision deficits. ADOA affects approximately 1
in 30,000 people worldwide. Currently, there is no approved treatment for people living with ADOA.

ABO-505 is designed to express a functional copy of human Opa1 in the retina following para-retinal injection. ABO-505 aims to take advantage of the robust optic nerve and
RGC transduction ability of AAV204 to deliver its genetic payload to the cells most affected by ADOA. Preclinical studies have confirmed expression of Opa1 in both cell
culture and the retinas of dosed wild-type and disease model animals. Initial efficacy results suggest an improvement in retinal signaling to the brain and improved visual acuity
in treated mutant mice. These studies were presented at the ASGCT Annual Meeting in May 2023.

Gene Therapy Treatments anchored in AIM™ Vector Platform

In 2016, we licensed a library of novel AAV capsids from UNC. The AIM™ vector system is a platform of AAV capsids capable of widespread central nervous system gene
transfer and can be used to confer high transduction efficiency for various therapeutic indications. In partnership with academic institutions, our own scientific research teams
have identified vectors within the AIM™ capsid library showing strong potential to successfully target and reach the central nervous system as well as ocular, lung, muscle,
liver, and other tissues. Based on continuing research by Abeona and our research partners, we have observed improvements in gene delivery to specific tissues compared to
currently available AAV technology. We believe AIM™ vectors also have the potential for redosing subjects who previously received certain AAV gene therapy or subjects who
have pre-existing antibodies to naturally occurring AAV serotypes.

Strategic Licensing Agreements

We  have  out-licensed  certain  clinical  and  research  programs,  including  for  the  treatment  of  Sanfilippo  syndrome  type  A  (MPS  IIIA)  to  Ultragenyx  Pharmaceutical  Inc.
(“Ultragenyx”),  and  for  CLN1  disease  (infantile  Batten  disease)  and  Rett  syndrome  to  Taysha  Gene  Therapies,  Inc.  (“Taysha”).  Under  the  terms  of  our  agreement  with
Ultragenyx, we are eligible to receive payments based on the achievement of certain sales milestones and royalties on net sales. Under our agreements with Taysha, we are
eligible to receive payments based on certain clinical, regulatory, and sales milestones and royalties on net sales.

Leveraging Leadership Position in Commercial-Scale Cell and Gene-Therapy Manufacturing

We have established a cGMP manufacturing facility, the Elisa Linton Center located in Cleveland, Ohio, which enables us to enhance supply chain control, establish tighter
quality  control  testing,  increase  supply  capacity,  reduce  production  costs  and  gain  manufacturing  efficiency  for  clinical  trials  related  to  our  product  candidates  and  ensure
commercial demand is met in the event our therapies receive marketing approval. Our facility is led by a team of highly skilled production, process/assay development and
quality control scientists with expertise in cell and gene therapy, particularly in cell culture, upstream manufacturing, downstream purification, assay development and wet lab
techniques.

We have completed our 16,000+ square foot manufacturing build-out in Cleveland, Ohio. The first phase, completed in 2018, was a 6,000 square foot state-of-the-art cGMP
production  facility  for  the  manufacturing  of  cell  and  gene  therapies.  The  facility  is  designed  to  initially  manufacture  clinical  drug  products  with  intent  of  manufacturing
commercial  grade  cGMP  drug  product. The  second  phase,  completed  in  2019,  was  the  completion  of  an  additional  8,000  square  feet  of  state-of-the-art  laboratory  space  to
support  our  expanding  quality  control,  process  development,  and  assay  development  teams.  The  second  phase  also  included  nearly  2,000  square  feet  of  cGMP  Inventory
Control space.

We  have  advanced  our  in-house  manufacturing  capabilities  for  pz-cel. The  product  is  manufactured  as  a  multilayer  cellular  sheet  containing  corrected  keratinocytes  that  is
fastened to a petrolatum gauze backing with surgical titanium ligating clips. Engineered sheets are applied over wound areas, where they provide keratinocytes with functional
Type VII collagen, providing immediate wound coverage and allowing for long-term wound healing. A key component to the pz-cel drug product manufacturing process is the
retroviral vector, which delivers the functional copy of the Collagen VII Alpha 1 cDNA to the autologous patient cells. Initially developed at the Indiana University Vector
Production Facility, we have transferred the cGMP manufacturing process for the LZRSE-Col7A1 retroviral vector to our Cleveland facility and have demonstrated analytical
comparability  between  IUVPF  and Abeona-produced  retroviral  vector.  In  order  to  support  licensure,  we  have  produced  three  cGMP  process  validation  lots  and  have  also
created and characterized a cGMP master cell bank and a working cell bank to support the cGMP production of the retroviral vector.

We  have  established AAV  vector  manufacturing  capabilities  that  use  the  triple  plasmid  transient  transfection  method.  We  insert,  or  transfect,  many  copies  of  three  DNA
plasmids encoding the specific therapeutic gene sequence, or transgene, the capsid coding sequence, and helper sequences into AAV-293 cells using a serum-free, suspension-
based bioreactor vector production technology. During an incubation period following transfection, each cell produces AAV vectors through biosynthesis using the cells’ natural
machinery. At the end of the incubation period, the newly generated AAV vectors are harvested, filtered, and purified in a multi-step process.

We  have  established  and  maintained  strong  and  collaborative  relationships  with  third-party  companies  specializing  in  the  testing  of  cell  and  gene  therapy  material  to
complement our process and assay development needs.

We  have  made  significant  investments  in  developing  optimized  manufacturing  processes  and  believe  that  our  processes  and  methods  developed  to  date  provide  a
comprehensive manufacturing process for pz-cel and AAV-based vector therapies, including:

● sufficient scale to support commercial manufacturing requirements for pz-cel
● processes related to biopsy, cell collection, storage and transportation as part of manufacturing for pz-cel
● processes related to product release testing for pz-cel
● processes related to the manufacture and release testing of retroviral vector
● establishing transportation and packaging processes and materials for finished pz-cel product
● proprietary AAV vector manufacturing processes and techniques that produce a highly purified product candidate
● AAV serum-free suspension technology that is readily scalable
● multiple assays to accurately characterize our process and the AAV vectors we produce
● a series of purification processes, which may be adapted and customized for multiple different AAV capsids, with a goal of higher concentrations of active vectors, and

that are essentially free of empty capsids.

We believe that these improvements will enable us to develop best-in-class, next-generation cell and gene therapy products. As we look to commercialize pz-cel (subject to
FDA approval), we have filed our BLA to support commercial manufacturing of pz-cel from our Cleveland facility.

Maintain Strong Intellectual Property Protection

We strive to protect our commercially important proprietary technology, inventions, and know-how, including by seeking, maintaining, and defending patent rights, both for
inventions developed internally and for inventions licensed from third parties. We also rely on trade secrets and know-how relating to our proprietary technology platforms,
continuing technological innovation, and in-licensing opportunities to develop, strengthen and maintain our position in the field of cell and gene therapy. We may also rely on
the additional protections afforded by data exclusivity (currently 12 years for biologics), other market exclusivities such as orphan drug exclusivity, and patent term extensions,
where applicable.

Our success may depend in part on our ability to obtain and maintain patents and other protections for commercially important technology, inventions, and know-how related to
our business; defend and enforce our patents; preserve the confidentiality of our trade secrets; and operate without infringing the valid enforceable patents and other intellectual
property rights of third parties. Our ability to stop third parties from making, having made, using, selling, offering to sell, or importing our products may depend on the extent to
which we have rights under valid and enforceable licenses, patents, or trade secrets that cover these activities. In some cases, these rights may need to be enforced by third-party
licensors. With respect to both licensed and company-owned intellectual property, we may not be granted patents with respect to any of our pending patent applications or with
respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be
commercially useful in protecting our commercial products and methods of manufacturing the same.

We  are  actively  seeking  U.S.  and  international  patent  protection,  together  with  our  licensors,  for  a  variety  of  technologies,  including AAV  capsids, AAV-based  biological
products, methods of designing novel AAV constructs, methods for treating diseases of interest, including RDEB, and methods for manufacturing, packaging, and transporting
our product candidates. We also intend to seek patent protection or rely upon trade secret rights to protect other technologies that may be used to discover and validate targets
and that may be used to identify and develop novel biological products. We seek protection, in part, through confidentiality and proprietary information agreements. We are a
party to various license agreements that give us rights to use specific technologies in our research and development, and future commercialization.

We expect to explore in due course strategies to support patent term extensions for all of our patent portfolios.

U.S. Biologic Products Development Process

In  the  United  States,  the  FDA  regulates  biologic  products  including  gene  therapy  products  under  the  Federal  Food,  Drug,  and  Cosmetic Act  (“FDCA”),  the  Public  Health
Service  Act  (“PHSA”),  and  regulations  implementing  these  laws.  The  FDCA,  PHSA  and  their  corresponding  regulations  govern,  among  other  things,  the  testing,
manufacturing, safety, efficacy, labeling, packaging, storage, record keeping, distribution, advertising, and promotion of biologic products. Applications to the FDA are required
before conducting human clinical testing of biologic products. FDA approval also must be obtained before marketing of biologic products. Gene therapy studies may also need
to  comply  with  the  National  Institutes  of  Health  (“NIH”)  Guidelines  for  Research  Involving  Recombinant  or  Synthetic  Nucleic Acid  Molecules  (“NIH  Guidelines”),  which
includes additional requirements, such as the review and approval of the study by an Institutional Biosafety Committee.

Within the FDA, the Center for Biologics Evaluation and Research (“CBER”) regulates gene therapy products. Within CBER, the review of gene therapy and related products
is  consolidated  in  the  Office  of  Tissues  and  Advanced  Therapies  (“OTAT”)  and  the  FDA  has  established  the  Cellular,  Tissue  and  Gene  Therapies  Advisory  Committee
(“CTGTAC”),  a  panel  of  medical  and  scientific  experts  and  consumer  representatives,  to  advise  CBER  on  its  reviews.  The  FDA  has  issued  a  growing  body  of  guidance
documents on CMC, clinical investigations and other areas of gene therapy development, all of which are intended to facilitate the industry’s development of gene therapy
products.

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

● completion  of  preclinical  laboratory  tests  and  in  vivo  studies  in  accordance  with  the  FDA’s  current  Good  Laboratory  Practice  (“GLP”)  regulations  and  applicable

requirements for the humane use of laboratory animals or other applicable regulations;

● submission to the FDA of an application for an IND, which allows human clinical trials to begin unless the FDA objects within 30 days;
● approval by an independent institutional review board (“IRB”), reviewing each clinical site before each clinical trial may be initiated;
● performance  of  adequate  and  well-controlled  human  clinical  trials  according  to  the  FDA’s  Good  Clinical  Practice  (“GCP”)  regulations,  and  any  additional
requirements for the protection of human research subjects and their health information, to establish the safety and efficacy of the proposed biologic product candidate
for its intended use;

● development of manufacturing processes to ensure the product candidate’s identity, strength, quality, purity, and potency;
● preparation and submission to the FDA of a BLA for marketing approval that includes substantial evidence of safety, purity and potency from results of nonclinical

testing and clinical trials;

● satisfactory  completion  of  an  FDA  pre-approval  inspection  of  the  manufacturing  facility  or  facilities  where  the  biologic  product  candidate  is  produced  to  assess
compliance  with  cGMP  and  to  assure  that  the  facilities,  methods  and  controls  are  adequate  to  preserve  the  biologic  product  candidate’s  identity,  safety,  strength,
quality, potency and purity;

● potential FDA audit of the nonclinical and clinical trial sites that generated the data in support of the BLA; and
● payment  of  user  fees  and  the  FDA  review  and  approval,  or  licensure,  of  the  BLA.  BLA  application  fees  for  products  designated  as  orphan  drugs  by  the  FDA  are

waived.

Before testing any biologic product candidate on humans, including a gene therapy product candidate, the product candidate must undergo preclinical testing. Preclinical tests,
also referred to as nonclinical studies, include laboratory evaluations of product chemistry, toxicity, and formulation, as well as in vivo studies to assess the potential safety and
activity of the product candidate. The conduct of the preclinical tests must comply with federal regulations and requirements including GLPs.

If a gene therapy trial is conducted at, or sponsored by, institutions receiving NIH funding for recombinant DNA research, the study must also comply with the NIH Guidelines.
Compliance with the NIH Guidelines is mandatory for investigators at institutions receiving NIH funds for research involving recombinant DNA. However, many companies
and other institutions, not otherwise subject to the NIH Guidelines, voluntarily follow them.

The clinical trial sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a
proposed clinical protocol, to the FDA as part of the IND. Some preclinical testing may continue even after the IND is submitted. The IND automatically becomes effective 30
days after receipt by the FDA, unless the FDA places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns
before the clinical trial can begin. The FDA also may impose clinical holds on a biologic product candidate at any time before or during clinical trials due to safety concerns or
non-compliance. If the FDA imposes a clinical hold, trials may not commence or recommence without FDA authorization and then only under terms authorized by the FDA.

Human clinical trials under an IND

Clinical trials involve the administration of the biologic product candidate to healthy volunteers or patients under the supervision of qualified investigators, which generally are
physicians not employed by, or under the control of, the trial sponsor. Investigators must also provide certain information to the clinical trial sponsors to allow the sponsors to
make certain financial disclosures to the FDA. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures,
subject selection and exclusion criteria and the parameters to be used to monitor subject safety, including stopping rules that assure a clinical trial will be stopped if certain
adverse  events  should  occur.  Each  protocol  and  any  amendments  to  the  protocol  must  be  submitted  to  the  FDA  as  part  of  the  IND.  Clinical  trials  must  be  conducted  and
monitored in accordance with the FDA’s regulations comprising the GCP requirements, including the requirement that all research subjects provide informed consent.

Further,  each  clinical  trial  must  be  reviewed  and  approved  by  an  IRB  at  or  servicing  each  institution  at  which  the  clinical  trial  will  be  conducted. An  IRB  is  charged  with
protecting  the  welfare  and  rights  of  trial  participants  and  considers  items  such  as  whether  the  risks  to  individuals  participating  in  the  clinical  trials  are  minimized  and  are
reasonable in relation to anticipated benefits. The IRB also approves communications to study subjects before a study commences at that site and the form and content of the
informed consent that must be signed by each clinical trial subject, or his or her legal representative, and must monitor the clinical trial until completed. Clinical trials involving
recombinant DNA also must be reviewed by an institutional biosafety committee (“IBC”), a local institutional committee that reviews and oversees basic and clinical research
that utilizes recombinant DNA at that institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment.

Information about certain clinical trials, including a description of the study and study results, must be submitted within specific timeframes to NIH for public dissemination on
their clinicaltrials.gov website. Sponsors or distributors of investigational products for the diagnosis, monitoring, or treatment of one or more serious diseases or conditions
must also have a publicly available policy on evaluating and responding to requests for expanded access requests.

Investigational biologics and therapeutic substances imported into the United States are also subject to regulation by the FDA. Further, the export of investigational products
outside of the United States is subject to regulatory requirements of the receiving country as well as U.S. export requirements under the FDCA.

12

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

● Phase  1:  The  biologic  product  candidate  initially  is  introduced  into  healthy  human  subjects  and  tested  for  safety,  dosage  tolerance,  absorption,  metabolism,
distribution, excretion and, if possible, to gain an early understanding of its effectiveness. In the case of some product candidates for severe or life-threatening diseases,
especially when the product candidate may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

● Phase 2: The biologic product candidate is evaluated in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the

efficacy of the product candidate for specific targeted diseases and to determine dosage tolerance, optimal dosage and dosing schedule.

● Phase  3:  The  biologic  product  candidate  is  administered  to  an  expanded  patient  population  at  geographically  dispersed  clinical  trial  sites  in  adequate  and  well-
controlled  clinical  trials  to  generate  sufficient  data  to  statistically  confirm  the  efficacy  and  safety  of  the  product  for  approval.  These  clinical  trials  are  intended  to
establish the overall risk/benefit ratio of the product candidate and provide an adequate basis for product labeling. Typically, two phase 3 trials are required by the FDA
for product approval. Under some limited circumstances, however, the FDA may approve a BLA based upon a single phase 3 clinical study plus confirmatory evidence
or a single large multicenter trial without confirmatory evidence.

Additional kinds of data may also help to support a BLA, such as patient experience data. Real world evidence may also support a BLA, and, for appropriate indications sought
through supplemental BLAs, data summaries may provide marketing application support. For genetically targeted products and variant protein targeted products intended to
address an unmet medical need in one or more patient subgroups with a serious or life threatening rare disease or condition, the FDA may allow a sponsor to rely upon data and
information  previously  developed  by  the  sponsor  or  for  which  the  sponsor  has  a  right  of  reference,  that  was  submitted  previously  to  support  an  approved  application  for  a
product that incorporates or utilizes the same or similar genetically targeted technology or a product that is the same or utilizes the same variant protein targeted drug as the
product that is the subject of the application.

Post-approval clinical trials, sometimes referred to as phase IV clinical trials, may be conducted or may be required by FDA after initial approval. These clinical trials are used
to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow-up.

During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and clinical trial investigators.
Annual progress reports detailing the results of the clinical trials must be submitted to the FDA.

Written IND safety reports must be promptly submitted to the FDA, IRBs, IBCs, and the investigators for serious and unexpected adverse events; any findings from other trials,
in vivo laboratory tests or in vitro testing that suggest a significant risk for human subjects; any clinically important increase in the rate of a serious suspected adverse reaction
over that listed in the protocol or investigator brochure, or other safety information. The sponsor must submit an IND safety report within 15 calendar days after the sponsor
determines  that  the  information  qualifies  for  reporting. The  sponsor  also  must  notify  the  FDA  of  any  unexpected  fatal  or  life-threatening  suspected  adverse  reaction  within
seven calendar days after the sponsor’s initial receipt of the information.

The FDA, the sponsor or its data safety monitoring board may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients
are  being  exposed  to  an  unacceptable  health  risk.  Similarly,  an  IRB  can  suspend  or  terminate  approval  of  a  clinical  trial  at  its  institution  if  the  clinical  trial  is  not  being
conducted in accordance with the IRB’s requirements or if the biologic product candidate has been associated with unexpected serious harm to patients. The FDA or an IRB
may also impose conditions on the conduct of a clinical trial.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Additional regulation for gene therapy clinical trials

In addition to the regulations discussed above, there are a number of additional standards that apply to clinical trials involving the use of gene therapy. The FDA has issued
various guidance documents regarding gene therapies, which outline additional factors that the FDA will consider at each of the above stages of development and relate to,
among  other  things:  the  proper  preclinical  assessment  of  gene  therapies;  the  CMC  information  that  should  be  included  in  an  IND  application;  the  proper  design  of  tests  to
measure product efficacy in support of an IND or BLA application; and long term patient and clinical study subject follow up and reporting requirements. The FDA has also
issued draft guidance specific to the development of gene therapy products for neurodegenerative diseases as such products may face special challenges related to CMCs and
clinical and preclinical development, due to the nature of the products and potential patient population (e.g., children), the heterogeneity of neurodegenerative disorders, the
route of administration, the volume of the product that can be administered, the delivery device, and the study population size.

Compliance with cGMP requirements

Manufacturers of biologics must comply with applicable cGMP regulations for both clinical and commercial supply. Manufacturers and others involved in the manufacture and
distribution  of  such  products  at  the  commercial  stage  also  must  register  their  establishments  with  the  FDA  and  certain  state  agencies  and  list  the  manufactured  products.
Recently,  the  information  that  must  be  submitted  to  FDA  regarding  manufactured  products  was  expanded  through  the  Coronavirus Aid,  Relief,  and  Economic  Security,  or
CARES, Act  to  include  the  volume  of  drugs  produced  during  the  prior  year.  Both  domestic  and  foreign  manufacturing  establishments  must  register  and  provide  additional
information  to  the  FDA  upon  their  initial  participation  in  the  manufacturing  process.  Establishments  may  be  subject  to  periodic,  unannounced  inspections  by  government
authorities  to  ensure  compliance  with  cGMP  requirements  and  other  laws.  Discovery  of  problems  may  result  in  a  government  entity  placing  restrictions  on  a  product,
manufacturer,  or  holder  of  an  approved  BLA,  and  may  extend  to  requiring  withdrawal  of  the  product  from  the  market. The  FDA  will  not  approve  an  application  unless  it
determines that the manufacturing processes and facilities comply with cGMP requirements and are adequate to assure consistent production of the product within required
specification.

Concurrent with clinical trials, companies usually complete additional preclinical studies and must also develop additional information about the physical characteristics of the
biologic  product  candidate  as  well  as  finalize  a  process  for  manufacturing  the  product  candidate  in  commercial  quantities  in  accordance  with  cGMP  requirements. To  help
reduce  the  risk  of  the  introduction  of  adventitious  agents  or  of  causing  other  adverse  events  with  the  use  of  biologic  products,  the  PHSA  emphasizes  the  importance  of
manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the
product candidate and, among other requirements, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of the final biologic product.
Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the biologic product candidate does not undergo
unacceptable deterioration over its shelf life.

U.S. review and approval processes

The results of the preclinical tests and clinical trials, together with detailed information relating to the product’s CMC and proposed labeling, among other things, are submitted
to the FDA as part of a BLA requesting approval to market the product for one or more indications.

For gene therapies, selecting patients with applicable genetic defects is a necessary condition to effective treatment. For the therapies we are currently developing, we believe
that diagnoses based on symptoms, in conjunction with existing genetic tests developed and administered by laboratories certified under the Clinical Laboratory Improvement
Amendments, are sufficient to select appropriate patients and will be permitted by the FDA. For future therapies, however, it may be necessary to use FDA-cleared or FDA-
approved  diagnostic  tests  to  select  patients  or  to  assure  the  safe  and  effective  use  of  therapies  in  appropriate  patients.  The  FDA  refers  to  such  tests  as  in  vitro  companion
diagnostic devices and the combination of the in vitro companion diagnostic device and the therapeutic would be considered to be a combination product.

14

 
 
 
 
 
 
 
 
 
 
The use of the two products together must be shown to be safe and effective for the proposed intended use and the labeling of the two products must reflect their combined use.
In some cases, the device component may require a separate premarket submission; for example, when the device component is intended for use with multiple drug products.
Sponsors  of  clinical  studies  using  investigational  devices  are  required  to  comply  with  FDA’s  investigational  device  exemption  regulations.  Once  approved  or  cleared,  the
sponsor of the device component submission (or the combination product submission, if both components are covered by one premarket submission) would need to comply
with FDA’s post-market device requirements, including establishment registration, device listing, device labeling, unique device identifier, quality system regulation, medical
device reporting, and reporting of corrections and removals requirements.

The FDA has a policy position that, when safe and effective use of a therapeutic product depends on a diagnostic device, the FDA generally will require approval or clearance
of the diagnostic device at the same time that the FDA approves the therapeutic product. The type of premarket submission required for a companion diagnostic device will
depend  on  the  FDA  classification  of  the  device.  A  premarket  approval,  or  PMA,  application  is  required  for  high  risk  devices  classified  as  Class  III;  a  510(k)  premarket
notification is required for moderate risk devices classified as Class II; and a de novo request may be used for novel devices not previously classified by the FDA that are low or
moderate risk.

The FDA may, however, approve a therapeutic product without the concurrent approval or clearance of a diagnostic device when the therapeutic product is intended to treat
serious and life-threatening conditions for which no alternative exists and the FDA determines that the benefits from the use of the drug/biologic outweigh the risks from the
lack of an approved/cleared companion diagnostic. The FDA would also consider whether additional protections, such as risk evaluation and mitigation strategies, or REMS, or
post-approval requirements, are necessary. At this point, it is unclear how the FDA will apply this policy to our gene therapy candidates. Should the FDA deem genetic tests
used for selecting appropriate patients for our therapies to be in vitro companion diagnostics requiring FDA clearance or approval, we may face significant delays or obstacles
in obtaining approval for a BLA. In addition, under the Pediatric Research Equity Act (“PREA”), a BLA or supplement to a BLA must contain data to assess the safety and
effectiveness of the biologic product candidate for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric
subpopulation for which the product candidate is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers. Unless otherwise required by
regulation, PREA does not apply to any biologic product candidate for an indication for which orphan designation has been granted.

Under the PDUFA, each BLA must be accompanied by a substantial user fee that must be paid at the time of the first submission of the application, even if the application is
being submitted on a rolling basis. The FDA adjusts the PDUFA user fees on an annual basis. Fee waivers or reductions are available in certain circumstances, including a
waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on BLAs for product candidates designated as orphan
drugs, unless the product candidate also includes a non-orphan indication.

The FDA reviews a BLA within 60 days of submission to determine if it is substantially complete before the agency accepts it for filing. The FDA may refuse to accept for
filing  any  BLA  that  it  deems  incomplete  or  not  properly  reviewable  at  the  time  of  submission  and  may  request  additional  information.  In  that  event,  the  BLA  must  be
resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing. Once the submission is accepted for
filing, the FDA begins an in-depth, substantive review of the BLA.

The FDA reviews the BLA to determine, among other things, whether the proposed product candidate is safe and potent, or effective, for its intended use, has an acceptable
purity  profile  and  whether  the  product  candidate  is  being  manufactured  in  accordance  with  cGMP  to  assure  and  preserve  the  product  candidate’s  identity,  safety,  strength,
quality, potency, and purity. The FDA may refer applications for novel biologic products or biologic products that present difficult questions of safety or efficacy to an advisory
committee, typically a panel that includes clinicians and other experts, for review, evaluation, and 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.
During  the  product  approval  process,  the  FDA  also  will  determine  whether  a  REMS  is  necessary  to  assure  the  safe  use  of  the  product  candidate. A  REMS  could  include
medication guides, physician communication plans and elements to assure safe use, such as restricted distribution methods, patient registries, and other risk minimization tools.
If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS; the FDA will not approve the BLA without a REMS, if required.

15

 
 
 
 
 
 
 
 
Before  approving  a  BLA,  the  FDA  will  inspect  the  facilities  at  which  the  product  candidate  is  manufactured.  The  FDA  will  not  approve  the  product  candidate  unless  it
determines that the manufacturing processes and facilities comply with cGMP requirements and are adequate to assure consistent production of the product candidate within
required  specifications. Additionally,  before  approving  a  BLA,  the  FDA  typically  will  inspect  one  or  more  clinical  sites  to  assure  that  the  clinical  trials  were  conducted  in
compliance with IND trial requirements and GCP requirements.

On  the  basis  of  the  BLA  and  accompanying  information,  including  the  results  of  the  inspection  of  the  manufacturing  facilities,  the  FDA  may  issue  an  approval  letter  or  a
complete response letter. An approval letter authorizes commercial marketing of the biologic product with specific prescribing information for specific indications. A complete
response  letter  (“CRL”)  generally  outlines  the  deficiencies  in  the  submission  and  may  require  substantial  additional  testing  or  information  for  the  FDA  to  reconsider  the
application. If a CRL is issued, the applicant may either: resubmit the marketing application, addressing all of the deficiencies identified in the letter; withdraw the application;
or request an opportunity for a hearing. If those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA, the FDA will issue an approval letter.

If a product candidate receives regulatory approval, the approval may be significantly limited to specific diseases, patient populations, and dosages or the indications for use
may otherwise be limited. Further, the FDA may require that certain contraindications, warnings, or precautions be included in the product labeling. The FDA also may not
approve  label  statements  that  are  necessary  for  successful  commercialization  and  marketing.  The  FDA  may  impose  restrictions  and  conditions  on  product  distribution,
prescribing or dispensing in the form of a REMS, or otherwise limit the scope of any approval. In addition, the FDA may require post-marketing clinical trials, sometimes
referred to as phase IV clinical trials, designed to further assess a biologic product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of
approved products that have been commercialized.

The FDA has agreed to specified performance goals in the review of BLAs under the PDUFA. One such goal is to review 90% of standard BLAs in 10 months after the FDA
accepts the BLA for filing, and 90% of priority BLAs in six months, whereupon a review decision is to be made. The FDA does not always meet its PDUFA goal dates for
standard and priority BLAs and its review goals are subject to change from time to time. The review process and the PDUFA goal date may also be extended if new information
is submitted to the application.

Orphan drug designation

Under the Orphan Drug Act, the FDA may designate a biologic product as an “orphan drug” if it is intended to treat a rare disease or condition (generally meaning that it affects
fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the cost of developing and making a biologic product
available in the United States for treatment of the disease or condition will be recovered from sales of the product). Additionally, sponsors must present a plausible hypothesis
for  clinical  superiority  to  obtain  orphan  drug  designation  if  there  is  a  product  already  approved  by  the  FDA  that  is  considered  by  the  FDA  to  be  the  same  as  the  already
approved product and is intended for the same indication. This hypothesis must be demonstrated to obtain orphan exclusivity. Orphan product designation must be requested
before submitting a BLA. After the FDA grants orphan product designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA.
If granted, prior to product approval, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical study costs, tax
advantages,  and  certain  user-fee  waivers.  The  tax  advantages,  however,  were  limited  in  the  2017  Tax  Cuts  and  Jobs Act.  Orphan  product  designation  does  not  shorten  the
duration of the regulatory review and approval process.

If  a  product  with  orphan  status  receives  the  first  FDA  approval  for  the  disease  or  condition  for  which  it  has  such  designation,  the  product  is  entitled  to  orphan  product
exclusivity, meaning that the FDA may not approve any other applications to market the same drug or biologic product for the same indication for seven years, except in limited
circumstances, such as a showing of clinical superiority to the product with orphan exclusivity or if the party holding the exclusivity fails to assure the availability of sufficient
quantities of the drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan product sameness decisions are an evolving space.
FDA has issued a final guidance document on how the agency will determine the “sameness” of gene therapy products. Pursuant to the guidance, “sameness” will depend on
the product’s transgene expression, viral vectors groups and variants, and other product features that may have a therapeutic effect. Generally, minor differences between gene
therapy products will not result in a finding that two products are different. Any FDA sameness determinations could impact our ability to receive approval for our product
candidates and to obtain or retain orphan drug exclusivity. Competitors additionally may receive approval of different products for the same indication for which the orphan
product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan medicinal product status in
the European Union has similar, but not identical, benefits.

Expedited development and review programs

The FDA is authorized to expedite the review of BLAs in several ways. Under the Fast Track program, the sponsor of a biologic product candidate may request the FDA to
designate the product for a specific indication as a Fast Track product concurrent with or after the filing of the IND. Biologic products are eligible for Fast Track designation if
they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition. Fast Track designation applies
to the combination of the product candidate and the specific indication for which it is being studied. In addition to other benefits, such as the ability to have greater interactions
with the FDA, the FDA may initiate review of sections of a Fast Track BLA before the application is complete, a process known as rolling review. This “rolling review” is
available if the applicant provides and the FDA approves a schedule for the remaining information.

Any product submitted to the FDA for marketing, including under a Fast Track program, may be eligible for other types of FDA programs intended to expedite development
and review, such as breakthrough therapy designation, priority review and accelerated approval.

● Breakthrough therapy designation: To qualify for the breakthrough therapy program, product candidates must be intended to treat a serious or life-threatening disease
or  condition  and  preliminary  clinical  evidence  must  indicate  that  such  product  candidates  may  demonstrate  substantial  improvement  on  one  or  more  clinically
significant endpoints over existing therapies. The FDA will seek to ensure the sponsor of a breakthrough therapy product candidate receives the following: intensive
guidance  on  an  efficient  drug  development  program;  intensive  involvement  of  senior  managers  and  experienced  staff  on  a  proactive,  collaborative,  and  cross-
disciplinary review; and rolling review.

● Priority review: A product candidate is eligible for priority review if it treats a serious condition and, if approved, it would be a significant improvement in the safety
or  effectiveness  of  the  treatment,  diagnosis  or  prevention  of  a  serious  condition  compared  to  marketed  products. The  FDA  aims  to  complete  its  review  of  priority
review applications within six months as opposed to 10 months for standard review.

● Accelerated approval: Drug or biologic products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful
therapeutic benefit over existing treatments may receive accelerated approval. Accelerated approval means that a product candidate may be approved on the basis of
adequate and well-controlled clinical trials establishing that the product candidate has an effect on a surrogate endpoint that is reasonably likely to predict a clinical
benefit, or on the basis of an effect on a clinical endpoint other than survival or irreversible morbidity or mortality or other clinical benefit, taking into account the
severity, rarity and prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require that a sponsor of
a drug or biologic product candidate receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials. In addition, the FDA currently
requires as a condition for accelerated approval pre-approval of promotional materials. Failure to conduct required post-approval studies, or confirm a clinical benefit
during post-marketing studies, will allow the FDA to withdraw the drug or biologic from the market on an expedited basis.

Fast Track designation, breakthrough therapy designation, priority review and accelerated approval do not change the standards for approval but may expedite the development
or approval process. Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or
decide that the time period for FDA review or approval will not be shortened.

Finally,  with  passage  of  the  21st  Century  Cures  Act  (the  “Cures  Act”)  in  December  2016,  Congress  authorized  the  FDA  to  accelerate  review  and  approval  of  products
designated as regenerative advanced therapies. A product is eligible for this designation if it is a regenerative medicine therapy (which may include a cell or gene therapy) that
is  intended  to  treat,  modify,  reverse,  or  cure  a  serious  or  life-threatening  disease  or  condition  and  preliminary  clinical  evidence  indicates  that  the  drug  has  the  potential  to
address unmet medical needs for such disease or condition. The benefits of a regenerative advanced therapy designation include early interactions with the FDA to expedite
development  and  review,  benefits  available  to  breakthrough  therapies,  potential  eligibility  for  priority  review  and  accelerated  approval  based  on  surrogate  or  intermediate
endpoints.

Post-approval requirements

Rigorous and extensive FDA regulation of biologic products continues after approval, particularly with respect to cGMP requirements. Manufacturers are required to comply
with  applicable  requirements  in  the  cGMP  regulations,  including  quality  control  and  quality  assurance  and  maintenance  of  records  and  documentation.  Other  post-approval
requirements  applicable  to  biologic  products  include  reporting  of  cGMP  deviations  that  may  affect  the  identity,  potency,  purity  and  overall  safety  of  a  distributed  product,
record-keeping requirements, reporting of adverse events, reporting updated safety and efficacy information, and complying with electronic record and signature requirements.

To  help  reduce  the  increased  risk  of  the  introduction  of  adventitious  agents,  the  PHSA  emphasizes  the  importance  of  manufacturing  controls  for  products  whose  attributes
cannot be precisely defined. The PHSA also provides authority to the FDA to immediately suspend licenses in situations where there exists a danger to public health, to prepare
or procure products in the event of shortages and critical public health needs, and to authorize the creation and enforcement of regulations to prevent the introduction or spread
of communicable diseases in the United States and between states. After a BLA is approved, the product also may be subject to official lot release. If the product is subject to
official lot release by the FDA, the manufacturer submits samples of each lot of product to the FDA, together with a release protocol, showing a summary of the history of
manufacture of the lot and the results of all tests performed on the lot. The FDA also may perform certain confirmatory tests on lots of some products before releasing the lots
for distribution. In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biologic products.

There also are continuing annual program user fee requirements for approved products, excluding orphan products. In addition, manufacturers and other entities involved in the
manufacture and distribution of approved therapeutics are subject to periodic announced and unannounced inspections by the FDA and these state agencies for compliance with
cGMP and other requirements, which impose certain procedural and documentation requirements upon the company and third-party manufacturers.

A sponsor also must comply with the FDA’s marketing, advertising, and promotion requirements, such as those related to direct-to-consumer advertising, the prohibition on
promoting products for uses or in patient populations that are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored scientific and
educational activities and promotional activities involving the Internet. A company can make only those claims relating to a product that are approved by the FDA. Physicians,
in their independent professional medical judgment, may prescribe legally available products for unapproved indications that are not described in the product’s labeling and that
differ from those tested and approved by the FDA. Biopharmaceutical companies, however, are required to promote their products only for the approved indications and in
accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a
company that is found to have improperly promoted off-label uses may be subject to significant liability, including, but not limited to, criminal and civil penalties under the
FDCA and False Claims Act, exclusion from participation in federal healthcare programs, mandatory compliance programs under corporate integrity agreements, suspension
and debarment from government contracts, and refusal of orders under existing government contracts.

In addition, the distribution of prescription biopharmaceutical samples is subject to the Prescription Drug Marketing Act, or PDMA, which regulates the distribution of samples
at the federal level. Both the PDMA and state laws limit the distribution of prescription biopharmaceutical product. Certain reporting related to samples is also required. Free
trial or starter prescriptions provided through pharmacies are also subject to regulations under the Medicaid Drug Rebate Program and potential liability under anti-kickback
and false claims laws.

Moreover,  the  enacted  Drug  Quality  and  Security Act,  or  DQSA,  imposed  obligations  on  sponsors  of  biopharmaceutical  products  related  to  product  tracking  and  tracing.
Among the requirements of this legislation, sponsors are required to provide certain information regarding the products to individuals and entities to which product ownership
is transferred, are required to label products with a product identifier, and are required to keep certain records regarding the product. The transfer of information to subsequent
product owners by sponsors is also required to be done electronically. Sponsors must also verify that purchasers of the sponsors’ products are appropriately licensed. Further,
under this legislation manufacturers have product investigation, quarantine, disposition, and notification responsibilities related to counterfeit, diverted, stolen, and intentionally
adulterated products that would result in serious adverse health consequences or death to humans, 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. Similar requirements additionally are and will be
imposed through this legislation on other companies within the biopharmaceutical product supply chain, such as distributors and dispensers, as well as certain sponsor licensees
and affiliates.

18

 
 
 
 
 
 
 
 
 
Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or
withdrawal of the product from the market as well as possible civil or criminal sanctions. Further, should new safety information arise, additional testing or FDA notification
may be required. In addition, changes to the manufacturing process or facility generally require prior FDA approval before being implemented and other types of changes to the
approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant or
manufacturer to administrative or judicial civil or criminal actions and adverse publicity. These actions could include refusal to approve pending applications or supplemental
applications,  withdrawal  of  an  approval,  clinical  hold,  suspension  or  termination  of  clinical  trial  by  an  IRB,  warning  or  untitled  letters,  product  recalls,  adverse  publicity,
product seizures, total or partial suspension of production or distribution, injunctions, fines or other monetary penalties, refusals of government contracts, mandated corrective
advertising  or  communications  to  healthcare  professionals  or  patients,  exclusion  from  participation  in  federal  and  state  healthcare  programs,  debarment,  restitution,
disgorgement of profits or other civil or criminal penalties.

U.S. patent term restoration and marketing exclusivity

Depending upon the timing, duration, and specifics of FDA approval of product candidates, some of a sponsor’s U.S. patents may be eligible for limited patent term extension
under the Drug Price Competition and Patent Term Restoration Act of 1984. The Hatch-Waxman Amendments permit a patent restoration term of up to five years to account for
patent term lost during the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the
product’s approval date. The patent term restoration period generally is one-half the time between the effective date of an IND and the submission date of a BLA plus the time
between the submission date of a BLA and the approval of that application. This period may also be reduced by any time that the applicant did not act with due diligence. Only
one patent applicable to an approved biologic product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent.
The United States Patent and Trademark Office (“USPTO”), in consultation with the FDA, reviews and approves the application for any patent term extension or restoration.

Pediatric exclusivity

Pediatric exclusivity is a type of non-patent marketing exclusivity in the United States that, if granted, provides for the attachment of an additional six months of marketing
protection  to  the  term  of  any  existing  regulatory  exclusivity,  including  the  non-patent  and  orphan  exclusivity. This  six-month  exclusivity  may  be  granted  if  a  BLA  sponsor
submits pediatric data that fairly responds to a written request from the FDA for such data. The data do not need to show the product to be effective in the pediatric population
studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports of requested pediatric studies are submitted to,
and accepted by, the FDA within the statutory time limits, whatever statutory or regulatory periods of exclusivity or patent protection that cover the product are extended by six
months. This is not a patent term extension, but it effectively extends the regulatory period during which the FDA cannot accept or approve a biosimilar application.

Biosimilars and exclusivity

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (“PPACA”), created an abbreviated approval pathway for
biologic products shown to be similar to, or interchangeable with, an FDA-licensed reference biologic product, referred to as biosimilars. For the FDA to approve a biosimilar
product, it must find that the biosimilar product is highly similar to the reference product notwithstanding minor differences in clinically inactive components, and that there are
no clinically meaningful differences between the reference product and proposed biosimilar product. Interchangeability requires that a product is biosimilar to the reference
product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product and, for products administered multiple times, the
biologic  and  the  reference  biologic  may  be  switched  after  one  has  been  previously  administered  without  increasing  safety  risks  or  risks  of  diminished  efficacy  relative  to
exclusive use of the reference biologic.

19

 
 
 
 
 
 
 
 
 
 
A reference biologic is granted 12 years of exclusivity from the time of first licensure of the reference product. An application for a biosimilar product may not be submitted to
the  FDA  until  four  years  following  approval  of  the  reference  product,  and  it  may  not  be  approved  until  12  years  thereafter.  These  exclusivity  provisions  only  apply  to
biosimilars—companies that rely on their own data and file a full BLA may be approved earlier than 12 years. Moreover, certain changes and supplements to an approved BLA,
and  subsequent  applications  filed  by  the  same  sponsor,  manufacturer,  licensor,  predecessor  in  interest,  or  other  related  entity  do  not  qualify  for  the  twelve-year  exclusivity
period.  The  PHSA  also  includes  provisions  to  protect  reference  products  that  have  patent  protection.  The  biosimilar  product  sponsor  and  reference  product  sponsor  may
exchange  certain  patent  and  product  information  for  the  purpose  of  determining  whether  there  should  be  a  legal  patent  challenge.  Based  on  the  outcome  of  negotiations
surrounding the exchanged information, the reference product sponsor may bring a patent infringement suit and injunction proceedings against the biosimilar product sponsor.
The biosimilar applicant may also be able to bring an action for declaratory judgment concerning the patent.

In an effort to increase competition in the biologic product marketplace, Congress, the executive branch, and the FDA have taken certain legislative and regulatory steps. For
example, in 2020 the FDA finalized a guidance to facilitate product importation. Moreover, the 2020 Further Consolidated Appropriations Act included provisions requiring
that  sponsors  of  approved  biologic  products,  including  those  subject  to  REMS,  provide  samples  of  the  approved  products  to  persons  developing  biosimilar  products  within
specified timeframes, in sufficient quantities, and on commercially reasonable market-based terms. Failure to do so can subject the approved product sponsor to civil actions,
penalties, and responsibility for attorney’s fees and costs of the civil action. This same bill also includes provisions with respect to shared and separate REMS programs for
reference and generic drug products.

Rare Pediatric Disease Voucher Program

Under the Rare Pediatric Disease Voucher Program, the FDA can award priority review vouchers to sponsors of rare pediatric disease products where the product is intended to
treat serious or life-threatening diseases that primarily affect individuals up to age 18. To qualify, the product must contain no active ingredient (including any ester or salt of the
active ingredient) that has been previously approved by the FDA. The application must also meet other qualifying criteria, including eligibility for FDA priority review. If the
necessary qualifying criteria are met, upon a sponsor’s request and product approval, the FDA may award a priority review voucher. This voucher may be transferred and may
be redeemed to receive priority review of a subsequent marketing application for a different product. Use of a priority review voucher is subject to an FDA user fee. As these
vouchers are transferable, sponsors may sell these vouchers for substantial sums of money. Vouchers may, however, be revoked by the FDA under certain circumstances and
sponsors of approved rare pediatric disease products must submit certain reports to the FDA. To take advantage of the benefits of this program, the product must be designated
by the FDA for a rare pediatric disease no later than September 30, 2024, and approved no later than September 30, 2026, unless the law is reauthorized by Congress.

Government regulation outside of the United States

In  addition  to  regulations  in  the  United  States,  sponsors  are  subject  to  a  variety  of  regulations  in  other  jurisdictions  governing,  among  other  things,  clinical  trials  and  any
commercial sales and distribution of biologic products. Because biologically-sourced raw materials are subject to unique contamination risks, their use may be restricted in
some countries.

Whether  or  not  a  sponsor  obtains  FDA  approval  for  a  product,  a  sponsor  must  obtain  the  requisite  approvals  from  regulatory  authorities  in  foreign  countries  prior  to  the
commencement  of  clinical  trials  or  marketing  of  the  product  in  those  countries.  Certain  countries  outside  of  the  United  States  have  a  similar  process  that  requires  the
submission of a clinical trial application, much like the IND, prior to the commencement of human clinical trials. Save where the Clinical Trial Regulation applies (see below)
in  relation  to  cross-border  trials,  in  the  European  Union,  for  example,  a  request  for  a  Clinical  Trial Authorization  (“CTA”)  must  be  submitted  to  the  competent  regulatory
authorities and the competent Ethics Committees in the European Union Member States in which the clinical trial takes place, much like the FDA and the IRB, respectively.
Once the CTA request is approved in accordance with the European Union and the European Union Member State’s requirements, clinical trial development may proceed.

20

 
 
 
 
 
 
 
 
 
The requirements and processes governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical
trials are conducted in accordance with GCPs and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

Failure to comply with applicable foreign regulatory requirements may result in, among other things, fines, suspension, variation or withdrawal of regulatory approvals, product
recalls, seizure of products, operating restrictions, and criminal prosecution.

European Union regulation and exclusivity

To obtain regulatory approval of an investigational biologic product under European Union regulatory systems, applicants must submit a marketing authorization application
(“MAA”).  The  grant  of  marketing  authorization  in  the  European  Union  for  products  containing  viable  human  tissues  or  cells  such  as  gene  therapy  medicinal  products  is
governed  by  Regulation  1394/2007/EC  on  advanced  therapy  medicinal  products,  read  in  combination  with  Directive  2001/83/EC  of  the  European  Parliament  and  of  the
Council, commonly known as the Community code on medicinal products and Regulation (EC) 726/2004 of the European Parliament and of the Council laying down Union
procedures for the authorization and supervision of medicinal products for human and veterinary use and establishing a European Medicines Agency. Regulation 1394/2007/EC
lays  down  specific  rules  concerning  the  authorization,  supervision  and  pharmacovigilance  of  gene  therapy  medicinal  products,  somatic  cell  therapy  medicinal  products  and
tissue  engineered  products.  Manufacturers  of  advanced  therapy  medicinal  products  must  demonstrate  the  quality,  safety  and  efficacy  of  their  products  to  the  European
Medicines  Agency  (“EMA”)  which  provides  an  opinion  regarding  the  application  for  marketing  authorization.  The  European  Commission  grants  or  refuses  marketing
authorization in light of the opinion delivered by EMA.

Innovative  medicinal  products  are  authorized  in  the  European  Union  based  on  a  full  marketing  authorization  application  (as  opposed  to  an  application  for  marketing
authorization  that  relies  on  data  in  the  marketing  authorization  dossier  for  another,  previously  approved  medicinal  product).  Applications  for  marketing  authorization  for
innovative medicinal products must contain the results of pharmaceutical tests, preclinical tests and clinical trials conducted with the medicinal product for which marketing
authorization is sought. Innovative medicinal products for which marketing authorization is granted are entitled to eight years of data exclusivity. During this period, applicants
for approval of generics or biosimilars of these innovative products cannot make an MMA relying on data contained in the marketing authorization dossier submitted for the
innovative medicinal product to support their application and such generics or biosimilars cannot be placed on the market until 10 years after the first EU marketing of the
reference product. The overall 10-year period will be extended to a maximum of 11 years if, during the first eight years of those 10 years, the marketing authorization holder
obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical
benefit in comparison with existing therapies. Even if a compound is considered to be a new chemical entity and the innovator is able to gain the period of data exclusivity,
another company, nevertheless, could also market another competing medicinal product for the same therapeutic indication if such company obtained marketing authorization
based on an MAA with a complete independent data package of pharmaceutical tests, preclinical tests and clinical trials.

Products receiving orphan designation in the European Union can receive 10 years of market exclusivity. During this 10-year period, the competent authorities of the European
Union  Member  States  and  European  Commission  may  not  accept  applications  or  grant  marketing  authorization  for  other  similar  medicinal  product  for  the  same  orphan
indication. There are, however, three exceptions to this principle. Marketing authorization may be granted to a similar medicinal product for the same orphan indication if:

● The second applicant can establish in its application that its medicinal product, although similar to the orphan medicinal product already authorized, is safer, more

effective or otherwise clinically superior;

● The holder of the marketing authorization for the original orphan medicinal product consents to a second orphan medicinal product application; or
● The holder of the marketing authorization for the original orphan medicinal product cannot supply sufficient quantities of orphan medicinal product.

21

 
 
 
 
 
 
 
 
 
 
 
 
An orphan product can also obtain an additional two years of market exclusivity in the European Union for the conduct of pediatric trials. The 10-year market exclusivity may
be  reduced  to  six  years  if,  at  the  end  of  the  fifth  year,  it  is  established  that  the  product  no  longer  meets  the  criteria  for  orphan  designation;  for  example,  if  the  product  is
sufficiently profitable and no longer justifies the maintenance of market exclusivity or if the manufacturer cannot produce sufficient quantities to supply the orphan population.

The criteria for designating an “orphan medicinal product” in the European Union are similar, in principle, to those in the United States. Orphan medicinal products are eligible
for  financial  incentives  such  as  reduction  of  fees  or  fee  waivers.  The  application  for  orphan  medicinal  product  designation  must  be  submitted  before  the  application  for
marketing authorization. Orphan medicinal product designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

In April  2014,  the  EU  adopted  a  new  Clinical  Trials  Regulation  (EU)  No  536/2014  (the  “Clinical  Trials  Regulation”),  which  replaced  the  current  Clinical  Trials  Directive
2001/20/EC (the “Clinical Trials Directive”) on January 31, 2022. The Clinical Trial Regulation has overhauled the previous system of approvals for clinical trials in the EU
whereby all clinical trial approvals were granted purely on a national basis. Specifically, the legislation, which is directly applicable in all member states, aims at simplifying
and streamlining the approval of clinical trials in the EU, whereby there is a streamlined application procedure via a single-entry point and strictly defined deadlines for the
assessment of clinical trial applications. However, the Clinical Trial Regulation does increase public disclosure requirements in relation to clinical trial information.

In the European Union there are also broadly equivalent regimes for the other issues addressed in relation to US regulation including cGMP requirements, accelerated access
(generally through so-called Conditional Marketing Authorizations), pediatric requirements and incentives and patent term restoration (supplementary protection certificates).

Other Healthcare Laws and Regulations

Healthcare providers, physicians and third-party payors play a primary role in the recommendation and use of pharmaceutical products that are granted marketing approval.
Arrangements  with  third-party  payors,  existing  or  potential  customers  and  referral  sources  are  subject  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and
regulations, and these laws and regulations may constrain the business or financial arrangements and relationships through which manufacturers market, sell and distribute the
products for which they obtain marketing approval. Such restrictions under applicable federal and state healthcare laws and regulations include the following:

● the federal Anti-Kickback Statute, which prohibits, among other things, persons, and entities from knowingly and willfully soliciting, receiving, offering or paying
remuneration, directly or indirectly, in cash or kind, in exchange for, or to induce, either the referral of an individual for, or the purchase, order or recommendation of,
any  good  or  service  for  which  payment  may  be  made  under  federal  healthcare  programs  such  as  the  Medicare  and  Medicaid  programs.  This  statute  has  been
interpreted  to  apply  to  arrangements  between  pharmaceutical  manufacturers,  on  the  one  hand,  and  prescribers,  purchasers,  and  formulary  managers  on  the  other.
Although a number of statutory exemptions and regulatory safe harbors exist to protect certain common activities from falling under the Anti-Kickback Statute, these
are narrow, and practices may not fall under the applicable safe harbors and exemptions. For example, the United States Department of Health and Human Services
recently promulgated a regulation that is effective in two phases. First, the regulation excludes from the definition of “remuneration” limited categories of (a) PBM
rebates or other reductions in price to a plan sponsor under Medicare Part D or a Medicaid Managed Care Organization plan reflected in point-of sale reductions in
price and (b) PBM service fees. Second, effective January 1, 2023, the regulation expressly provides that rebates to plan sponsors under Medicare Part D either directly
to the plan sponsor under Medicare Part D, or indirectly through a pharmacy benefit manager will not be protected under the anti-kickback discount safe harbor. The
PPACA amended the intent requirement of the federal Anti-Kickback Statute. A person or entity no longer needs to have actual knowledge of this statute or specific
intent to violate it in order to commit a violation;

22

 
 
 
 
 
 
 
 
 
 
● the federal false claims and civil monetary penalties laws, including the civil False Claims Act (the “FCA”), which prohibit, among other things, individuals, or entities
from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid or other third-party payors that are false or fraudulent, or making
a false statement to avoid, decrease, or conceal an obligation to pay money to the federal government. Certain marketing practices, including off-label promotion, also
may implicate the FCA. FCA claims may be pursued by whistleblowers through qui tam actions, even if the government declines to intervene and civil liability may be
predicated on reckless disregard for the truth. The PPACA also codified case law that a claim including items or services resulting from a violation of the federal Anti-
Kickback  Statute  constitutes  a  false  or  fraudulent  claim  for  purposes  of  the  FCA.  Separately,  the  criminal  federal  False  Claims  Act  imposes  criminal  fines  or
imprisonment against individuals or entities who make or present a claim to the government knowing such claim to be false, fictitious, or fraudulent;

● the federal Physician Payments Sunshine Act, which requires certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available
under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services
(“CMS”), information related to payments and other transfers of value made to or at the request of covered recipients, such as, but not limited to, physicians, physician
assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  registered  nurse  anesthetists  and  teaching  hospitals,  as  well  as  ownership  and  investment  interests
held by physicians and their immediate family. Payments made to physicians and certain research institutions for clinical trials are included within the ambit of this
law. Reported information is made publicly available in searchable formats by CMS;

● additional federal false statements and fraud and abuse statutes prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud or to 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, a healthcare benefit
program, regardless of whether the payor is public or private, in connection with the delivery or payment for health care benefits, 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.  PPACA  amended  the  intent  requirement  of  certain  of  these  criminal  statutes  under  the  Health
Insurance Portability and Accountability Act of 1996 (“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; and

● state and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by
any  third-party  payor,  including  commercial  insurers;  state  laws  that  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical  industry’s  voluntary
compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare
providers  and  other  potential  referral  sources;  state  laws  that  require  drug  manufacturers  to  report  information  related  to  payments  and  other  transfers  of  value  to
physicians and other healthcare providers or marketing expenditures; and European Union and state laws governing the privacy and security of health information in
certain circumstances, many of which differ from each other in significant ways, may be stricter than those applicable in the US and may not have the same effect, thus
complicating compliance efforts.

Violation  of  the  laws  described  above  or  any  other  governmental  laws  and  regulations  may  result  in  penalties,  including  civil  and  criminal  penalties,  damages,  fines,  the
curtailment or restructuring of operations, the exclusion from participation in federal and state healthcare programs, debarment from government contracting or refusal of orders
under existing contracts, corporate integrity agreements or consent decrees, disgorgement, contractual damages, reputational harm, diminished profits and future earnings, and
imprisonment. Furthermore, efforts to ensure that business activities and business arrangements comply with applicable healthcare laws and regulations can be costly.

Data Privacy and Security

● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH Act, and similar state laws impose obligations
on certain entities with respect to safeguarding the privacy, security and transmission of protected health information. HIPAA’s security and certain privacy standards
are directly applicable to persons or organizations of covered entities, other than members of the covered entity’s workforce, that create, receive, maintain or transmit
protected  health  information  on  behalf  of  a  covered  entity  for  a  function  or  activity  regulated  by  HIPAA.  The  HITECH Act  strengthened  the  civil  and  criminal
penalties  that  may  be  imposed  against  covered  entities,  business  associates  and  individuals,  and  gave  state  attorneys  general  new  authority  to  file  civil  actions  for
damages  or  injunctions  in  federal  courts  to  enforce  the  federal  HIPAA  laws  and  seek  attorneys’  fees  and  costs  associated  with  pursuing  federal  civil  actions.  In
addition, other federal and state laws, such as the California Consumer Privacy Act, may regulate the privacy and security of information that we maintain, many of
which may differ from each other in significant ways and may not be preempted by HIPAA; and

● the General European Data Protection Regulation (“GDPR”), which became applicable May 25, 2018, harmonizes data privacy laws across Europe. The GDPR sets
forth  rules  relating  to  the  protection  with  regard  to  the  processing  and  transfer  of  personal  data  as  well  as  an  individual’s  right  to  the  protection  of  personal  data,
including  medical  information  and  clinical  trial  related  data.  In  addition,  there  are  rules  relating  to  the  export  of  personal  data  outside  the  European  Union  and  in
particular there are certain challenges in relation to export to the United States.

Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any products for which we may obtain regulatory approval. In the United States, sales of any
product candidates for which regulatory approval for commercial sale is obtained will depend in part on the availability of coverage and adequate reimbursement from third-
party payors. Third-party payors include government authorities and health programs in the United States such as Medicare and Medicaid, managed care providers, private
health  insurers  and  other  organizations. These  third-party  payors  are  increasingly  reducing  reimbursements  for  medical  products  and  services. The  process  for  determining
whether a payor will provide coverage for a drug product may be separate from the process for setting the reimbursement rate that the payor will pay for the drug product.
Third-party payors may limit coverage to specific drug products on an approved list, or formulary, which might not include all FDA-approved drugs for a particular indication.
Additionally, the containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The U.S.
government,  state  legislatures  and  foreign  governments  have  shown  significant  interest  in  implementing  cost-containment  programs,  including  price  controls,  required
disclosures  of  pricing  and  sensitive  cost  data,  requirement  for  payment  of  manufacturer  rebates  and  negotiation  of  supplemental  rebates,  restrictions  on  reimbursement  and
requirements  for  substitution  of  generic  products.  Coverage  policies  and  third-party  reimbursement  rates  may  change  at  any  time.  Even  if  favorable  coverage  and
reimbursement  status  is  attained  for  one  or  more  products  for  which  we  receive  regulatory  approval,  less  favorable  coverage  policies  and  reimbursement  rates  may  be
implemented in the future.

In the EU, pricing and reimbursement schemes vary widely from country to country. Some countries provide that products may be marketed only after a reimbursement price
has been agreed. Some countries may require the completion of additional studies as part of health technology assessment that compare the cost-effectiveness of a particular
product candidate to currently available therapies. EU member states may approve a specific price for a product, or it may instead adopt a system of direct or indirect controls
on  the  profitability  of  the  company  placing  the  product  on  the  market.  Other  member  states  allow  companies  to  fix  their  own  prices  for  products  but  monitor  and  control
company profits. The downward pressure on health care costs has become intense. As a result, increasingly high barriers are being erected to the entry of new products. In
addition,  in  some  countries,  cross-border  imports  from  low-priced  markets  exert  competitive  pressure  that  may  reduce  pricing  within  a  country. Any  country  that  has  price
controls or reimbursement limitations may not allow favorable reimbursement and pricing arrangements.

24

 
 
 
 
 
 
 
 
 
 
 
 
Health Reform

The United States and some foreign jurisdictions are considering or have enacted a number of reform proposals to change the healthcare system. There is significant interest in
promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality, or expanding access. In the United States, the pharmaceutical
industry has been a particular focus of these efforts. For example, healthcare reform measures under the Affordable Care Act included increased Medicaid rebates, expanded the
340B drug discount program, and changes requiring manufacturer discounts currently set at 70 percent on Part D utilization in the Part D coverage gap or “donut hole” and
multiple provisions that could affect the profitability of our drug products. There is continuing development of value-based pricing and reimbursement models. Moreover, on
November 27, 2020, CMS issued an interim final rule implementing a Most Favored Nation payment model under which reimbursement for certain Medicare Part B drugs and
biologicals  will  be  based  on  a  price  that  reflects  the  lowest  per  capita  Gross  Domestic  Product-adjusted  (GDP-adjusted)  price  of  any  non-U.S.  member  country  of  the
Organization  for  Economic  Co-operation  and  Development  (OECD)  with  a  GDP  per  capita  that  is  at  least  sixty  percent  of  the  U.S.  GDP  per  capita.  Current  and  future
healthcare  reform  measures  may  significantly  affect  our  sale  of  any  products,  and  we  continue  to  face  major  uncertainty  due  to  the  status  of  major  legislative  initiatives
surrounding healthcare reform.

Additional Regulation

In  addition  to  the  foregoing,  state  and  federal  laws  regarding  environmental  protection  and  hazardous  substances,  including  the  Occupational  Safety  and  Health  Act,  the
Resource Conservation and Recovery Act and the Toxic Substances Control Act, affect our business. These and other laws govern the use, handling and disposal of various
biologic and chemical substances used in, and wastes generated by, operations. If our operations result in contamination of the environment or expose individuals to hazardous
substances, we could be liable for damages and governmental fines. Equivalent laws have been adopted in other countries that impose similar obligations.

U.S. Foreign Corrupt Practices Act

The  U.S.  Foreign  Corrupt  Practices Act  (“FCPA”),  prohibits  U.S.  corporations  and  individuals  from  engaging  in  certain  activities  to  obtain  or  retain  business  abroad  or  to
influence a person working in an official capacity. It is illegal to pay, offer to pay or authorize the payment of anything of value to any foreign government official, government
staff member, political party, or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity. The scope of the
FCPA  includes  interactions  with  certain  healthcare  professionals  in  many  countries.  Equivalent  laws  have  been  adopted  in  other  foreign  countries  that  impose  similar
obligations.

Competition

Companies  that  are  currently  engaged  in  gene  therapy  or  companies  not  yet  focused  on  developing  cell  and  gene  therapies  could  at  any  time  decide  to  develop  therapies
relevant to our business. Many of our competitors, either alone or with their strategic partners, may have substantially greater financial, technical, and human resources than we
do and may have significantly greater experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of product candidates
and  commercializing  those  product  candidates. Accordingly,  our  competitors  may  be  more  successful  than  us  in  obtaining  approval  for  product  candidates  and  achieving
widespread  market  acceptance.  Our  competitors’  product  candidates  may  be  more  effective,  or  more  effectively  marketed  and  sold,  than  any  product  candidate  we  may
commercialize  and  may  render  our  treatments  obsolete  or  non-competitive  before  we  can  recover  the  expenses  of  developing  and  commercializing  any  of  our  product
candidates.

Mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors.
These  competitors  also  may  compete  with  us  in  recruiting  and  retaining  qualified  scientific  and  management  personnel  and  establishing  clinical  trial  sites  and  subject
registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Smaller or early-stage companies may also prove to be
significant competitors, particularly through collaborative arrangements with large and established companies.

25

 
 
 
 
 
 
 
 
 
 
 
We  anticipate  facing  intense  and  increasing  competition  as  new  product  candidates  enter  the  market  and  advanced  technologies  become  available.  We  expect  any  product
candidates  that  we  develop  and  commercialize  to  compete  on  the  basis  of,  among  other  things,  efficacy,  safety,  convenience  of  administration  and  delivery,  price,  and  the
availability of reimbursement from government and other third-party payors.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side
effects, are more convenient or are less expensive than any products that we may develop. 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.

ITEM 1A. RISK FACTORS

Our  business,  financial  condition,  financial  results,  and  future  growth  prospects  are  subject  to  a  number  of  risks  and  uncertainties,  including  those  set  forth  below.  The
occurrence of any of the following risks could have a material adverse effect on our business, financial condition, financial results, and future growth prospects.

Our business is subject to numerous risks and uncertainties, including those described in Item 1A “Risk Factors.” These risks include, but are not limited to the following:

RISK FACTOR SUMMARY

● Our  cell  and  gene  therapy  product  candidates  are  based  on  proprietary  methodologies,  which  makes  it  difficult  to  predict  the  time  and  cost  of  product  candidate
development and regulatory approval. Additionally, regulatory requirements governing cell and gene therapy products have evolved and may continue to change in the
future.

● If we do not obtain the necessary U.S. or worldwide regulatory approvals to commercialize pz-cel, we will not be able to sell pz-cel.
● Even  if  we  receive  regulatory  approval  for  pz-cel,  our  lead  drug  candidate,  we  may  not  be  able  to  successfully  manufacture  or  commercialize  the  product  and  the

revenue that we generate from its sales, if any, may be limited.

● We may encounter substantial delays in our clinical studies, or we may fail to demonstrate safety and efficacy to the satisfaction of applicable regulatory authorities.

Additionally, we may find it difficult to enroll patients in our clinical studies, which could delay or prevent clinical studies of our product candidates.

● We have received and may apply for additional designations such as breakthrough therapy designation, RMAT designation, fast track designation, and rare pediatric
disease designation from the FDA intended to facilitate or encourage product candidate development. We may not receive any such designations or be able to maintain
them. Moreover, any such designations may not lead to faster development or regulatory review or approval and it does not increase the likelihood that our product
candidates will receive marketing approval.

● While certain of our product candidates have received orphan drug designation from the FDA, there is no guarantee that we will be able to maintain this designation,

receive this designation for any of our other product candidates, or receive or maintain any corresponding benefits, including periods of exclusivity.

● Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.
● We  could  experience  production  problems  in  our  manufacturing  facility  that  result  in  delays  in  our  development  or  commercialization  programs.  We  might  also
experience  delays  in  manufacturing  if  any  of  our  vendors,  contract  laboratories  or  suppliers  are  found  to  be  out  of  compliance  with  current  Good  Manufacturing
Practice.

● If we fail to comply with applicable regulations, the relevant regulatory authority may require remedial measures that may be costly or time-consuming to implement

and that may include the suspension of a clinical trial or commercial sales or the closure of a manufacturing facility.

● The widespread outbreak of an illness, communicable disease, or any other public health crisis could adversely affect our business, results of operations and financial

condition.

● We expect to rely on third parties, and these third parties may not perform satisfactorily. Additionally, our reliance on third parties requires us to share our trade secrets,

which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated.

● Our drug candidates are subject to the risks of failure inherent in the development of pharmaceutical products based on new technologies, and our failure to develop

safe and commercially viable drugs would severely limit our ability to become profitable or to achieve significant revenues.

● We may be unable to successfully develop, market, or commercialize our products or our product candidates without establishing new relationships and maintaining
current relationships and our ability to successfully commercialize, and market our product candidates could be limited if a number of these existing relationships are
terminated.

● We may incur substantial product liability expenses due to the use or misuse of our products for which we may be unable to obtain insurance coverage.

27

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● Our ability to successfully develop and commercialize our drug candidates will substantially depend upon the availability of reimbursement funds for the costs of the

resulting drugs and related treatments.

● The market may not accept any pharmaceutical products that we develop, and adverse public perception of gene therapy products may negatively affect demand for, or

regulatory approval of, our product candidates.

● We may be subject to federal, state, and foreign healthcare laws and regulations, including fraud and abuse laws, false claims laws, health information privacy and

security laws and data privacy laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

● Trends toward managed health care and downward price pressures on medical products and services may limit our ability to profitably sell any drugs that we may

develop.

● Our rights to develop and commercialize our product candidates are subject to, in part, the terms and conditions of licenses granted to us by others.
● If we are unable to obtain and maintain patent protection for our product candidates and technology, or if the scope of the patent protection obtained is not sufficiently

broad, our competitors could develop and commercialize products and technology similar or identical to ours.
● Our intellectual property licenses with third parties may be subject to disagreements over contract interpretation.
● We may not be successful in obtaining necessary rights to our product candidates through acquisitions and in-licenses.
● Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court. We may not be able to protect our trade secrets in court,

and intellectual property litigation could cause us to spend substantial resources.

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

our business.

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

employers or claims asserting ownership of what we regard as our own intellectual property.

● If we do not obtain patent term extension and data exclusivity for our product candidates, our business may be harmed.
● We have experienced a history of losses; we expect to incur future losses and we may be unable to obtain necessary additional capital to fund operations in the future.

We do not have significant operating revenue and may never achieve profitability.

● We expect to continue to need to raise additional capital to operate our business, and our failure to obtain funding when needed or on terms that are favorable to us

may force us to delay, reduce or eliminate our development programs or aspects thereof.

● Failure to achieve and maintain effective internal controls could have a material adverse effect on our business.
● The market price of our common stock may be volatile and adversely affected by several factors.
● Raising  additional  funds  by  issuing  securities  or  through  licensing  or  lending  arrangements  or  through  our  at-the-market  sale  agreement  may  cause  dilution  to  our

existing stockholders, restrict our operations or require us to relinquish proprietary rights.

● Breaches of data security or unauthorized disclosures of personal information could effect our business or make us subject to liability.

Risks related to the discovery and development of our product candidates

Our  cell  and  gene  therapy  product  candidates  are  based  on  proprietary  methodologies,  which  makes  it  difficult  to  predict  the  time  and  cost  of  product  candidate
development and subsequently obtaining regulatory approval. Only a few gene therapy products have been approved in the U.S. and the EU.

We  have  concentrated  our  therapeutic  product  research  and  development  efforts  on  our  cell  and  gene  therapy  platform,  and  our  future  success  depends  on  the  successful
development of this therapeutic approach. There can be no assurance that any development problems we experience in the future related to our cell and gene therapy platform
will  not  cause  significant  delays  or  unanticipated  costs,  or  that  such  development  problems  can  be  solved.  We  may  also  experience  delays  in  developing  a  sustainable,
reproducible and commercial-scale manufacturing process or transferring that process to commercial partners, which may prevent us from completing our clinical studies or
commercializing our products on a timely or profitable basis, if at all.

In addition, the clinical study requirements of the FDA, the EMA, and other regulatory agencies and the criteria these regulators use to determine the safety and efficacy of a
product candidate vary substantially according to the type, complexity, novelty and intended use and market of the potential products. The regulatory approval process for novel
product candidates such as ours can be more expensive and take longer than for other, better known or more extensively studied pharmaceutical or other product candidates.
Given that only a few gene therapy products have been approved in the Western world, it is not possible to predict how long it will take or how much it will cost to obtain
regulatory approvals for our product candidates in the United States, the EU or other jurisdictions. Approvals by the EMA and the European Commission may not be indicative
of what the FDA may require for approval.

Regulatory  requirements  governing  cell  and  gene  therapy  products  have  evolved  and  may  continue  to  change  in  the  future.  For  example,  the  FDA  has  established  the
Office Tissues and Advanced Therapies within CBER to consolidate the review of gene therapy and related products, and the Cellular, Tissue and Gene Therapies Advisory
Committee to advise CBER on its review.

Regulatory requirements in the United States and in other jurisdictions governing gene therapy products have changed frequently and will continue to change in the future as
scientific knowledge is acquired. The FDA and EMA have each expressed interest in further regulating gene therapy. For example, the FDA has established the Office Tissues
and Advanced Therapies within CBER to consolidate the review of gene therapy and related products, and the Cellular, Tissue and Gene Therapies Advisory Committee to
advise CBER on its review. Over the last few years, FDA, through CBER, has provided significant guidance regarding the development of gene therapies. Additionally, the
EMA  advocates  a  risk-based  approach  to  the  development  of  a  gene  therapy  product. Agencies  at  both  the  federal  and  state  level  in  the  United  States,  as  well  as  the  U.S.
congressional committees and other governments or governing agencies, have also expressed interest in further regulating the biotechnology industry. Such action may delay or
prevent  commercialization  of  some,  or  all,  of  our  product  candidates.  These  regulatory  review  agencies,  committees  and  advisory  groups  and  the  new  requirements  and
guidelines they promulgate may lengthen the regulatory review process, require us to perform additional or larger studies, increase our development costs, lead to changes in
regulatory positions and interpretations, delay or prevent approval and commercialization of these treatment candidates or lead to significant post-approval studies, limitations,
or restrictions. As we advance our product candidates, we will be required to consult with these regulatory and advisory groups and comply with applicable requirements and
guidelines. If we fail to do so, we may be required to delay or discontinue development of our product candidates. Delay or failure to obtain, or unexpected costs in obtaining,
the regulatory approval necessary to bring a potential product to market could decrease our ability to generate sufficient product revenue to maintain our business.

We  may  encounter  substantial  delays  in  our  clinical  studies,  such  as  clinical  holds,  or  we  may  fail  to  demonstrate  safety  and  efficacy  to  the  satisfaction  of  applicable
regulatory authorities.

Before obtaining marketing approval from regulatory authorities for the sale of our product candidates, we must conduct extensive clinical studies to demonstrate the safety,
purity and potency, and efficacy, of the product candidates in humans. Clinical testing is expensive, time-consuming, and uncertain as to outcome. This is especially true for
rare and/or complicated diseases. We cannot guarantee that any clinical studies will be conducted as planned or completed on schedule, if at all. A failure of one or more clinical
studies can occur at any stage of testing.

The results of preclinical studies, preliminary study results, and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials or
the  ultimately  completed  trial.  Product  candidates  in  later  stages  of  clinical  trials  may  fail  to  show  the  desired  safety  and  efficacy  traits  despite  having  progressed  through
preclinical studies and initial clinical trials. Preclinical and early clinical studies may also reveal unfavorable product candidate characteristics, including safety concerns.

We  may  also  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 or continue a clinical trial, conduct a clinical trial at a prospective trial site, or amend trial

protocols, or regulators or IRBs may require that we modify or amend our clinical trial protocols;

● 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 our

contract research organizations (“CROs’);

● regulators  may  require  us  to  perform  additional  or  unanticipated  clinical  trials  to  obtain  approval  or  we  may  be  subject  to  additional  post-marketing  testing,

surveillance, or REMS requirements to maintain regulatory approval;

● flaws in a clinical trial may not become apparent until the trial is well advanced;
● clinical trials of our product candidates may produce negative or inconclusive results, or our studies may fail to reach the necessary level of statistical significance, and

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

● clinical trials of our product candidates may require us to provide follow-up patient visits for safety for a minimum of five years even if we were to terminate and/or

abandon a product development program;

● our third-party contractors may fail to comply with regulatory requirements or the clinical trial protocol, or fail to meet their contractual obligations to us in a timely

manner, or at all, or we may be required to engage in additional clinical trial site monitoring;

● we, the regulators, or IRBs may require the suspension or termination of clinical research for various reasons, including noncompliance with regulatory requirements
or a finding that the participants are being exposed to unacceptable health risks, undesirable side effects, or other unexpected characteristics (alone or in combination
with other products) of the product candidate, or due to findings of undesirable effects caused by a chemically or mechanistically similar therapeutic or therapeutic
candidate;

● changes in marketing approval and regulatory review policies or changes in or the enactment of additional statutes or regulations;
● the cost of clinical trials of and marketing applications for our product candidates may be greater than we anticipate;
● the supply or quality of our product candidates or other materials necessary to conduct clinical trials may be insufficient or inadequate;
● we  may  decide,  or  regulators  may  require  us,  to  conduct  or  gather,  as  applicable,  additional  clinical  trials,  analyses,  reports,  data,  or  preclinical  trials,  or  we  may

abandon product development programs;

● we may fail to reach an agreement with regulators or IRBs regarding the scope, design, or implementation of our clinical trials. For instance, the FDA or comparable

foreign regulatory authorities may require changes to our study design that make further study impractical or not financially prudent;

● we may have delays in adding new investigators or clinical trial sites, or we may experience a withdrawal of clinical trial sites;
● there may be regulatory questions or disagreements regarding interpretations of data and results, or new information may emerge regarding our product candidates;
● we  may  make  changes  to  our  product  candidates  or  their  manufacturing  process  that  necessitate  additional  studies  or  that  result  in  our  product  candidates  not

performing as expected;

● the FDA or comparable foreign regulatory authorities may disagree with our study design, including endpoints, or our interpretation of data from preclinical studies

and clinical trials or find that a product candidate’s benefits do not outweigh its safety risks;

● the FDA or comparable foreign regulatory authorities may not accept data from studies with clinical trial sites in foreign countries;
● the FDA or comparable regulatory authorities may disagree with our intended indications;
● the FDA or comparable foreign regulatory authorities may fail to approve or subsequently find fault with the manufacturing processes or our contract manufacturer’s

manufacturing facility for clinical and future commercial supplies;

30

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● the data collected from clinical trials of our product candidates may not be sufficient to the satisfaction of the FDA or comparable foreign regulatory authorities to
support the submission of a marketing application, or other comparable submission in foreign jurisdictions or to obtain regulatory approval in the United States or
elsewhere;

● if one of our product candidates does not receive marketing approval in one country, it may impact our ability to receive marketing approval in other countries;
● the FDA or comparable regulatory authorities may take longer than we anticipate to make a decision on our product candidates; and
● we  may  not  be  able  to  demonstrate  that  a  product  candidate  provides  an  advantage  over  current  standards  of  care  or  current  or  future  competitive  therapies  in

development.

Delays in launching clinical trials resulting from FDA or other regulatory actions, such as a clinical hold letter, would delay the commercialization of our product candidates
and our ability to generate revenue, which would have an adverse effect on our business. For example, in September 2019, we received a clinical hold letter in connection with
our phase 3 clinical trial for pz-cel stating that the FDA would not provide approval for us to begin our planned phase 3 clinical trial for pz-cel until we submitted additional
data points on transport stability of pz-cel to clinical sites. Although the FDA removed the clinical hold in December 2019 and provided clearance for us to proceed with our
planned phase 3 clinical trial, we may encounter similar delays in our clinical studies in the future.

Significant  delays  relating  to  any  preclinical  or  clinical  trials  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. This may prevent us from receiving marketing approvals and impair our ability to successfully
commercialize our product candidates. If any of the foregoing were to occur, our business, financial condition, results of operations, and prospects will be materially harmed.

We may find it difficult to enroll patients in our clinical studies, which could delay or prevent clinical studies of our product candidates.

Identifying and qualifying patients to participate in clinical studies of our product candidates is critical to our success. The timing of our clinical studies depends on the speed at
which we can recruit eligible patients to participate in testing our product candidates. We have experienced delays in some of our clinical studies due to the ultra-rare nature of
the diseases we aim to treat, and we may experience similar delays in the future. If patients are unwilling to participate in our cell and gene therapy studies because of negative
publicity from adverse events in the biotechnology or gene therapy industries or for other reasons, including competitive clinical studies for similar patient populations, the
timeline for recruiting patients, conducting studies, and obtaining regulatory approval of potential products may be delayed. These delays could result in increased costs, delays
in advancing our product development, delays in testing the effectiveness of our technology or termination of the clinical studies altogether.

We may not be able to identify, recruit or enroll a sufficient number of patients, or those with required or desired characteristics to achieve diversity in a study, to complete our
clinical studies in a timely manner. Patient enrollment is affected by factors including:

● severity of the disease under investigation;
● design of the study protocol;
● size and nature of the patient population;
● eligibility criteria for and design of the study in question;
● perceived risks and benefits of the product candidate under study, including as a result of adverse effects observed in similar or competing therapies;
● proximity and availability of clinical study sites for prospective patients;
● availability of competing therapies and clinical studies;
● efforts to facilitate timely enrollment in clinical studies;
● ability to compensate patients for their time and effort;
● risk that enrolled patients will drop out before completion or not return for post-treatment follow-up;
● inability to obtain or maintain patient informed consents;
● effectiveness of publicity created by clinical trial sites regarding the trial;
● patient referral practices of physicians; and
● ability to monitor patients adequately during and after treatment.

31

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We also plan to seek initial marketing approval in the European Union in addition to the U.S. Our ability to successfully initiate, enroll and complete a clinical study in any
foreign country is subject to additional risks unique to conducting business in foreign countries, such as different standards for the conduct of clinical studies; different laws,
medical standards, and regulatory requirements; and the ability to establish or manage relationships with treatment centers, contract research organizations and physicians.

If we have difficulty enrolling a sufficient number of patients to conduct our clinical studies as planned our development costs may increase, the time for completion of clinical
trials may increase, we may need to delay, limit or terminate ongoing or planned clinical studies, any of which would have an adverse effect on our business.

Our products or product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval or commercialization.

Undesirable side effects caused by our products or product candidates, including adverse events associated with our product candidates, could interrupt, delay, or halt clinical
trials and could result in the denial of regulatory approval or more limited approvals by the FDA, EMA or other regulatory authorities for any or all targeted indications, or the
inclusion of unfavorable information in our product labeling, such as limitations on the indicated uses or populations for which the products may be marketed or distributed, a
label  with  significant  safety  warnings,  including  boxed  warnings,  contraindications,  and  precautions,  a  label  without  statements  necessary  or  desirable  for  successful
commercialization, or may result in requirements for costly post-marketing testing and surveillance, or other requirements, including REMS, to monitor the safety or efficacy of
the products. These could in turn prevent us from commercializing our products or product candidates and generating revenues from their sale.

In addition, if we or others identify undesirable side effects caused by our product candidates after receipt of marketing approval, the regulatory authorities may require the
addition  of  restrictive  labeling  statements.  Regulatory  authorities  may  withdraw  their  approval  of  the  product.  We  also  may  be  required  to  change  the  way  the  product  is
administered or conduct additional clinical trials. Any of these events could prevent us from achieving or maintaining market acceptance of the affected products or product
candidate or could substantially increase the costs and expenses of commercializing the products or product candidate, which in turn could delay or prevent us from generating
significant revenues from its sale or adversely affect our reputation.

Even if we complete the necessary preclinical and clinical studies, we cannot predict when or if we will obtain regulatory approval to commercialize a product candidate or
the approval may be for a narrower indication than we expect.

We cannot commercialize a product until the appropriate regulatory authorities have reviewed and approved the product candidate. Even if our product candidates demonstrate
safety and efficacy in clinical studies, the regulatory agencies may not complete their review processes in a timely manner, or we may not be able to obtain regulatory approval.
Additional delays may result if an FDA Advisory Committee or other regulatory advisory group or authority recommends non-approval or restrictions on approval. In addition,
we  may  experience  delays  or  rejections  based  on  additional  government  regulation  from  future  legislation  or  administrative  action,  or  changes  in  regulatory  agency  policy
during  the  period  of  product  development,  clinical  studies,  and  the  review  process.  Regulatory  agencies  also  may  approve  a  treatment  candidate  for  fewer  or  more  limited
indications, populations, or uses than requested or may grant approval subject to the performance of post-marketing studies, surveillance, or other requirements. In addition,
regulatory  agencies  may  not  approve  the  labeling  claims  that  are  necessary  or  desirable  for  the  successful  commercialization  of  our  treatment  candidates,  or  may  require
significant safety warnings, including black box warnings, contraindications, and precautions. For example, the development of our product candidates for pediatric use is an
important part of our current business strategy, and if we are unable to obtain regulatory approval for the desired age ranges, our business may suffer.

32

 
 
 
 
 
 
 
 
 
We have received and may apply for additional designations intended to facilitate or encourage product candidate development. We may not receive any such designations
or be able to maintain them. Moreover, any such designations may not lead to faster development or regulatory review or approval and it does not increase the likelihood
that our product candidates will receive marketing approval.

Our product candidates have received regulatory designations including breakthrough therapy designation, RMAT designation, fast track designation, and rare pediatric disease
designation from the FDA. In the future and as appropriate, we may seek additional product designations. Receipt of such a designation is within the discretion of the FDA.
Even  if  we  believe  one  of  our  product  candidates  meets  the  criteria  for  a  designation,  the  FDA  may  disagree.  In  any  event,  the  receipt  of  such  a  designation  for  a  product
candidate may not result in a faster development process, review, or approval compared to product candidates considered for approval under conventional FDA procedures and
does not assure ultimate marketing approval by the FDA. In addition, the FDA may later decide that the product candidates no longer meet the designation conditions, in which
case any granted designations may be revoked. Finally, specifically with respect to our rare pediatric disease designations, if we are not able to obtain FDA approval of our
designated product candidates before the statute sunsets, we would not be eligible to receive priority review vouchers.

Certain of our product candidates have received orphan drug designation from the FDA, there is no guarantee that we will be able to maintain this designation, receive
this designation for any of our other product candidates, or receive or maintain any corresponding benefits, including periods of exclusivity.

While orphan drug designation provides certain advantages, it neither shortens the development time or regulatory review time of a product candidate nor gives the product
candidate any advantage in the regulatory review or approval process. Generally, if a product candidate with orphan drug designation subsequently receives marketing approval
before another product considered by the FDA or comparable foreign regulatory authorities to be the same, for the same orphan indication, the product is entitled to a period of
marketing exclusivity, which precludes the FDA or comparable foreign regulatory authorities from approving another marketing application for the same drug or biologic for
the same indication for seven years. We may not be able to obtain any future orphan drug designations that we apply for, orphan drug designations do not guarantee that we will
be able to successfully develop our product candidates, and there is no guarantee that we will be able to maintain any orphan drug designations that we receive. For instance,
orphan drug designation may be revoked if the FDA finds that the request for designation contained an untrue statement of material fact or omitted material information, or if
the FDA finds that the product candidate was not eligible for designation at the time of the submission of the request. Moreover, we may ultimately not receive any period of
regulatory exclusivity if our product candidates are approved. For instance, we may not receive orphan product regulatory exclusivity if the indication for which we receive
FDA approval is broader than the designation. Orphan exclusivity may also be lost for the same reasons that the designation may be lost. Orphan exclusivity may further be lost
if we are unable to assure a sufficient quantity of the product to meet the needs of patients with the rare disease or condition.

Even if we obtain orphan exclusivity for any of our current or future product candidates, that exclusivity may not effectively protect the product from competition as different
products can be approved for the same condition or products that are the same as ours can be approved for different conditions. Even after an orphan product is approved, the
FDA or comparable foreign regulatory authorities can also subsequently approve a product containing the same principal molecular features for the same condition if the FDA
concludes that the later product is clinically superior. The FDA may further grant orphan drug designation to multiple sponsors for the same compound or active molecule and
for  the  same  indication.  If  another  sponsor  receives  FDA  or  comparable  foreign  regulatory  authority  approval  for  such  product  before  we  do,  we  would  be  prevented  from
launching our product for the orphan indication for a period of at least seven years unless we can demonstrate clinical superiority. FDA’s thinking around sameness with respect
to  gene  therapies,  and  thus  the  circumstances  when  clinical  superiority  would  need  to  be  shown,  is  evolving.  While  the  agency  has  issued  guidance  on  the  topic,  certain
decisions may need to be made on a case by case basis, given the novelty of the technology. Moreover, third-party payors may reimburse for products off-label even if not
indicated for the orphan condition.

33

 
 
 
 
 
 
 
Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.

Even  if  we  obtain  regulatory  approval  in  a  jurisdiction,  regulatory  authorities  may  still  impose  significant  restrictions  on  the  indicated  uses  or  marketing  of  our  product
candidates  or  impose  ongoing  requirements  for  potentially  costly  post-approval  studies,  post-market  surveillance  or  patient  or  drug  restrictions.  Moreover,  the  FDA  and
comparable foreign regulatory authorities will continue to closely monitor the safety profile of any product even after approval, including gene therapy specific requirements
for long term follow up. Additionally, the holder of an approved BLA is obligated to monitor and report adverse events and any failure of a product to meet the specifications in
the BLA. The holder of an approved BLA must also submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product
labeling  or  manufacturing  process.  Advertising  and  promotional  materials  must  comply  with  FDA  rules  and  are  subject  to  FDA  review,  in  addition  to  other  potentially
applicable federal and state laws.

In  addition,  product  manufacturers  and  their  facilities  are  subject  to  payment  of  user  fees  and  continual  review  and  periodic  inspections  by  the  FDA  and  other  regulatory
authorities for compliance with cGMP and adherence to commitments made in the BLA. If we or a regulatory agency discovers previously unknown problems with a product,
such as adverse events of unanticipated severity or frequency, or that the product is less effective than previously thought, or problems with the facility where the product is
manufactured, a regulatory agency may impose restrictions relative to that product or the manufacturing facility, including requiring recall or withdrawal of the product from
the market or suspension of manufacturing.

If  we  fail  to  comply  with  applicable  regulatory  requirements  following  approval  of  any  of  our  product  candidates  or  during  product  development,  or  if  we  later  discovery
previously unknown safety, efficacy, or manufacturing issues, the following may result:

● restrictions  on  manufacturing,  distribution,  marketing,  or  labeling  of  such  products,  including  restrictions  on  the  indication  or  approved  patient  population,  and

required additional warnings, such as black box warnings, contraindications, and precautions;

● requirements to conduct post-marketing studies or clinical trials, or to institute risk mitigation strategies, such as REMS;
● issuance of corrective information;
● the product may become less competitive, we may face reputational harm, or we may face liability for any harm caused to patients or subjects;
● modifications on the way the product is administered;
● modifications on promotional pieces;
● issuance of warning, untitled, or cyber letters asserting that we are in violation of the law, or of safety alerts, Dear Healthcare Provider letters, press releases, or other

communications containing warnings or other safety information about the product;

● injunction or imposition civil or criminal penalties or monetary fines, restitution, or disgorgement of profits or revenues;
● suspension or withdrawal of regulatory approval;
● suspension or termination of any ongoing clinical studies;
● refusal to approve a pending marketing application, such as a BLA or supplements to a BLA submitted by us;
● seizure, detention, or recall of product;
● refusal to permit the import or export of our products; or
● refusal to allow us to enter into supply contracts, including government contracts, exclusion from federal healthcare programs, FDA debarment, consent decrees, or

corporate integrity agreements.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The
occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenues.

34

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The FDA’s policies may change, and additional government regulations may be enacted, that could prevent, limit or delay regulatory approval of our product candidates, that
could limit the marketability of our product candidates, or that could impose additional regulatory obligations on us. For example, a change in administration in the U.S. may
result in new, revised, postponed or frozen regulatory requirements and associated compliance obligations. Changes in medical practice and standard of care may also impact
the marketability of our product candidates. If we are slow or unable to adapt to changes in existing requirements, standards of care, or the adoption of new requirements or
policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and be subject to regulatory enforcement
action.

Should  any  of  the  above  actions  take  place,  they  could  adversely  affect  our  ability  to  achieve  or  sustain  profitability.  Further,  the  cost  of  compliance  with  post-approval
regulations may have a negative effect on our operating results and financial condition.

Risks related to manufacturing

We could experience production problems in our manufacturing facilities that result in delays in our development or commercialization programs or otherwise adversely
affect our business.

We are susceptible to production interruptions that may impede our ability to manufacture cell and gene therapy products and produce an adequate product supply to support
clinical  trials  and  potentially  future  commercialization.  Several  factors  could  cause  production  interruptions,  including  equipment  malfunctions,  facility  contamination,  raw
material shortages or contamination, natural disasters, public health emergencies such as the COVID-19 pandemic, disruption in utility services, human error, or disruptions in
the operations of our suppliers. Our products and product candidates are biologic drugs requiring processing steps that are more complex than those required for most chemical
pharmaceuticals. We characterize our processes and products, and perform testing to ensure the safety, quality and efficacy of each product produced. While we take significant
measures to fully understand and characterize each product, the steps we take may not be sufficient to ensure that a given lot will perform in the intended manner.

There are several risks specific to the manufacturing process for pz-cel which require close attention. As an autologous product there are challenges associated with viability of
biopsies as an incoming material. Due to variables such as the fragility of RDEB skin and site of the biopsy, initiation of autologous keratinocyte growth and expansion can be
challenging or may be extended beyond the scheduled timing. Another concern during manufacturing is the slowing of cell proliferation, resulting in extended manufacturing
time. If pre-release criteria are not met, the production process must be stopped, and a new biopsy must be obtained. If release criteria are out of range, epidermal sheets must
be discarded and the manufacturing process must be repeated.

We currently do not have a backup manufacturer to supply clinical trial material for pz-cel. An alternative manufacturer would need to be qualified, through regulatory filings,
which  could  result  in  delays  to  our  clinical  trial  timeline.  The  regulatory  authorities  also  may  require  additional  clinical  trials  if  a  new  manufacturer  is  relied  upon  for
commercial production. Switching manufacturers may involve substantial costs and could result in a delay in our desired clinical and commercial timelines.

Accordingly, we employ multiple steps to control our manufacturing process to assure that the products or product candidate is made strictly and consistently in compliance
with the process. Problems with the manufacturing process, including even minor deviations from the normal process, could result in product defects or manufacturing failures
that result in lot failures, product recalls, product liability claims, or insufficient inventory. We may encounter problems achieving adequate quantities and quality of clinical
grade materials that meet FDA, EU or other applicable standards or specifications with consistent and acceptable production yields and costs. In addition, the FDA, EMA and
other foreign regulatory authorities may require us to submit samples of any lot of any approved product together with the protocols showing the results of applicable tests at
any  time.  Under  some  circumstances,  the  FDA,  EMA  or  other  foreign  regulatory  authorities  may  require  that  we  not  distribute  a  lot  until  the  agency  authorizes  its  release.
Slight deviations in the manufacturing process, including those affecting quality attributes and stability, may result in unacceptable changes in the product that could result in lot
failures or product recalls for approved and marketed products.

35

 
 
 
 
 
 
 
 
 
 
Lot failures or product recalls could cause us to delay product launches or clinical trials, which could be costly to us and otherwise harm our business, financial condition,
results of operations and prospects. We also may encounter problems hiring and retaining the experienced scientific, quality control and manufacturing personnel needed to
operate  our  manufacturing  process,  which  could  result  in  delays  in  our  production  or  difficulties  in  maintaining  compliance  with  applicable  regulatory  requirements. Any
problems in our manufacturing process or facilities could make us a less attractive collaborator for potential partners, including larger pharmaceutical companies and academic
research  institutions,  which  could  limit  our  access  to  additional  attractive  development  programs.  Problems  in  our  manufacturing  process  including  in  internal  and  external
facilities providing supply necessary for manufacturing or challenges with procuring supplies, such as due to global trade policies, also could restrict our ability to meet clinical
trial supply demand, and eventually market demand for any product candidates for which we may receive marketing approval. Disruptions in our manufacturing process may
delay or disrupt our commercialization efforts.

If we or any of our vendors, contract laboratories or suppliers are found to be out of compliance with cGMP, we may experience delays or disruptions in manufacturing
while  we  implement  corrective  actions  or  work  with  these  third  parties  to  remedy  the  violation  or  while  we  work  to  identify  suitable  replacement  vendors,  contract
laboratories or suppliers.

To obtain regulatory approval for commercial manufacturing, we will need to continue to ensure that all of our processes, methods and equipment are compliant with cGMP
and perform extensive audits of vendors, contract laboratories and suppliers. The cGMP requirements govern quality control of the manufacturing process and documentation
policies and procedures. Complying with cGMP requires us to expend time, money and effort in production, record keeping and quality control to assure that the product meets
applicable specifications and other requirements. If we fail to comply with these requirements, we would be subject to possible regulatory action and may not be permitted to
sell any products that we may develop.

We may rely on third parties to conduct aspects of our product manufacturing, and these third parties may not perform satisfactorily. We may rely on third parties to produce
certain materials for our product candidates and, therefore, we can control only certain aspects of their activities.

We and our third-party suppliers, laboratories, and manufacturers may be unable to comply with our specifications, cGMP requirements and with other FDA, state, and foreign
regulatory  requirements.  Poor  control  of  production  processes  can  lead  to  the  introduction  of  adventitious  agents  or  other  contaminants,  or  to  inadvertent  changes  in  the
properties or stability of a product candidate that may not be detectable in final product testing. If we or 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 or our contract manufacturers will not be able to secure
or maintain regulatory approval for their manufacturing facilities. Any such deviations may also require remedial measures that may be costly and/or time-consuming for us or
a third party to implement and may include the temporary or permanent suspension of a clinical trial or commercial sales or the temporary or permanent closure of a facility.
Any such remedial measures imposed upon or by us or third parties with whom we contract could materially harm our business. Any delays in obtaining products or product
candidates that comply with the applicable regulatory requirements may result in delays to clinical trials, product approvals, and commercialization. It may also require that we
conduct additional studies.

We have manufacturing agreements with third parties that provide for, among other things, production of product candidates for our current and future early-stage clinical trials.
Under  certain  circumstances,  the  other  party  is  entitled  to  terminate  its  arrangement  with  us.  If  we  need  to  enter  into  alternative  arrangements,  it  could  delay  our  product
development activities. Our reliance on third parties for certain manufacturing activities will reduce our control over these activities but will not relieve us of our responsibility
to ensure compliance with all required regulations. If a third party does not successfully carry out its contractual duties, meet expected deadlines or manufacture our product
candidates in accordance with regulatory requirements, or if there are disagreements between us and any such third party, we will not be able to complete, or may be delayed in
completing, the preclinical studies required to support future IND submissions and the clinical trials required for approval of our product candidates. In such instances, we may
need  to  enter  into  an  appropriate  replacement  third-party  relationship,  which  may  not  be  readily  available  or  on  acceptable  terms,  which  would  cause  additional  delay  or
increased expense prior to the approval of our product candidates and would thereby have a material adverse effect on our business, financial condition, results of operations
and prospects.

36

 
 
 
 
 
 
 
 
In addition, if the FDA or a comparable foreign regulatory authority does not approve our or a third party’s facilities for the manufacture of our 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  and
maintain regulatory approval for or market our product candidates, if approved. Any new manufacturers would need to either obtain or develop the necessary manufacturing
know-how, and obtain the necessary equipment and materials, which may take substantial time and investment. We must also receive FDA approval for the use of any new
manufacturers  for  commercial  supply. We  may  not  succeed  in  our  efforts  to  establish  manufacturing  relationships  or  other  alternative  arrangements  for  any  of  our  product
candidates, components, and programs. For example, our product candidates may compete with other products and product candidates for access to manufacturing facilities.
There are a limited number of manufacturers that operate under cGMP regulations and that are both capable of manufacturing for us and willing to do so.

The  manufacture  of  biologic  products  requires  significant  expertise  and  capital  investment,  including  the  development  of  advanced  manufacturing  techniques  and  process
controls.  Manufacturers  of  therapeutics  often  encounter  difficulties  in  production,  particularly  in  scaling  up  initial  production.  These  problems  include  difficulties  with
production costs and yields, quality control, including stability of the product candidate and quality assurance testing, shortages of qualified personnel, and compliance with
strictly enforced federal, state, and foreign regulations. If we or our manufacturers were to encounter any of these difficulties and were unable to perform as agreed, our ability
to provide product candidates to patients in our clinical trials and for commercial use, if approved, would be jeopardized.

Our reliance on these third parties entails risks to which we would not be subject if we manufactured the product candidates ourselves, including:

● reduced control for certain aspects of manufacturing activities;
● reduced control over the protection of our trade secrets and know-how from misappropriation or inadvertent disclosure;
● inability to negotiate manufacturing agreements with third parties under commercially reasonable terms;

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

● termination or nonrenewal of manufacturing and service agreements with third parties in a manner or at a time that is costly or damaging to us; and
● disruptions  to  the  operations  of  our  third-party  manufacturers  and  service  providers  caused  by  conditions  unrelated  to  our  business  or  operations,  including  the

bankruptcy of the manufacturer or service provider.

Any of these events could lead to clinical trial delays or failure to obtain regulatory approval or impact our ability to successfully commercialize future product candidates.
Some of these events could be the basis for FDA action or action of equivalent competent authorities in foreign jurisdictions, including injunction, recall, seizure or total or
partial  suspension  of  product  manufacturing.  Failure  to  comply  with  ongoing  regulatory  requirements  could  cause  us  to  suspend  production  or  put  in  place  costly  or  time-
consuming remedial measures.

If  any  inspection  or  audit  by  regulatory  authorities  identifies  a  failure  to  comply  with  applicable  regulations,  or  if  a  violation  of  product  specifications  or  applicable
regulations occurs independent of such an inspection or audit, the relevant regulatory authority may require remedial measures that may be costly or time-consuming to
implement and that may include the temporary or permanent suspension of a clinical trial or commercial sales or the temporary or permanent closure of a manufacturing
facility.

Regulatory authorities may inspect or audit the manufacturing facilities for our products and product candidates at any time. Any such remedial measures imposed upon us
could materially harm our business, financial condition, results of operations and prospects. If we fail to comply with applicable cGMP regulations, FDA and foreign regulatory
authorities could impose regulatory sanctions including, among other things, refusal to approve a pending application for a new product candidate or suspension or revocation
of a pre-existing approval. Such an occurrence may cause our business, financial condition, results of operations and prospects to be materially harmed. Additionally, if supply
from our facility is interrupted, there could be a significant disruption in commercial supply of any of our product candidates for which we obtain marketing approval, and in
clinical supply for our product candidates.

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

Although  we  maintain  general  liability  insurance  and  workers’  compensation  insurance  for  certain  costs  and  expenses  that  we  may  incur  due  to  injuries  to  our  employees
resulting from the use of hazardous materials or other work-related injuries, 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 biologic and hazardous materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations, which have tended to become more
stringent over time. These current or future laws and regulations may impair our research, development, or production efforts. Failure to comply with these laws and regulations
also may result in substantial fines, penalties or other sanctions or liabilities, which could harm our business, financial condition, results of operations and prospects.

The widespread outbreak of an illness, communicable disease, or any other public health crisis could adversely affect our business, results of operations and financial
condition.

We could be negatively impacted by the widespread outbreak of an illness, communicable disease, or any other public health crisis that results in economic or trade disruptions,
including the disruption of global supply chains. The COVID-19 pandemic negatively impacted the economy on a global, national, and local level, disrupted global supply
chains,  and  created  volatility  and  disruption  of  financial  markets.  Responses  from  governmental  authorities  and  companies  to  reduce  the  spread  of  COVID-19  affected
economic  activity  through  various  containment  measures  including,  among  others,  business  closures,  work  stoppages,  quarantine  and  work-from-home  guidelines,  limiting
capacity at public spaces and events, vaccination requirements, or restrictions of global and regional travel. Another outbreak of an illness, a communicable disease, or any
other public health crisis, and any resulting impacts, such as an extended period of global supply chain and/or economic disruption, labor shortages, or government-mandated
actions in response to such public health crisis could materially affect our business, results of operations, access to sources of liquidity, and financial condition.

Risks related to our reliance on third-parties

We expect to rely on third parties to conduct some or all aspects of our viral vector production, drug product manufacturing, research and preclinical, and clinical testing,
and these third parties may not perform satisfactorily.

We do not expect to independently conduct all aspects of our viral vector production, drug product manufacturing and distribution, research and preclinical, and clinical testing.
We currently rely, and expect to continue to rely, on third parties with respect to these matters. In some cases, these third parties are academic, research or similar institutions
that may not apply the same quality control protocols utilized in certain commercial settings.

38

 
 
 
 
 
 
 
 
 
 
 
Our  reliance  on  these  third  parties  for  research  and  development  activities  reduces  our  control  over  these  activities  but  does  not  relieve  us  of  our  responsibility  to  ensure
compliance with all required regulations and study protocols. For example, for product candidates that we develop and commercialize on our own, we remain responsible for
ensuring that each of our IND-enabling studies and clinical studies are conducted in accordance with the study plan and protocols, and that our viral vectors and drug products
are manufactured in accordance with GMP as applied in the relevant jurisdictions. We must also ensure that our preclinical trials are conducted in accordance with GLPs, as
appropriate. Moreover, the FDA and comparable foreign regulatory authorities require us to comply with 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 requirements through periodic inspections. If we or any of our third-party service providers fail to comply with applicable regulatory requirements, we or they
may be subject to enforcement or other legal actions, the data generated in our trials or manufacturing development may be deemed unreliable, and the FDA or comparable
foreign regulatory authorities may require us to perform additional studies and manufacturing development. If these third parties do not successfully carry out their contractual
duties, meet expected deadlines, conduct our studies in accordance with regulatory requirements or our stated study plans and protocols, or manufacture our viral vectors and
drug products in accordance with cGMP, or if they need to be replaced or if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to our
protocols, regulatory requirements or for other reasons, we will not be able to complete, or may be delayed in completing, the preclinical and clinical studies and manufacturing
process validation activities required to support future IND, MAA and BLA submissions and approval of our product candidates.

Any  of  these  third  parties  may  terminate  their  engagements  with  us  at  any  time.  If  we  need  to  enter  into  alternative  arrangements,  it  could  delay  our  product  development
activities. Any of these events could lead to clinical study delays or failure to obtain regulatory approval or impact our ability to successfully commercialize future products.
Some of these events could be the basis for FDA action, including injunction, recall, seizure or total or partial suspension of production.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be
misappropriated or disclosed.

Because we rely on third parties to manufacture our vectors and our product candidates, and because we collaborate with various organizations and academic institutions on the
advancement of our cell and gene therapy platform, we must, at times, share trade secrets with them. We seek to protect our proprietary technology in part by entering into
confidentiality  agreements  and,  if  applicable,  material  transfer  agreements,  collaborative  research  agreements,  consulting  agreements  or  other  similar  agreements  with  our
collaborators, advisors, employees, and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third
parties to use or disclose our confidential information, such as trade secrets. Despite the contractual provisions employed when working with third parties, the need to share
trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology
of others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s
discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on our business.

In addition, these agreements typically restrict the ability of our collaborators, advisors, employees, and consultants to publish data potentially relating to our trade secrets. Our
academic collaborators typically have rights to publish data, provided that we are notified in advance and may delay publication for a specified time in order to secure our
intellectual property rights arising from the collaboration. In other cases, publication rights are controlled exclusively by us, although in some cases we may share these rights
with  other  parties.  We  also  conduct  joint  research  and  development  programs  that  may  require  us  to  share  trade  secrets  under  the  terms  of  our  research  and  development
partnerships or similar agreements. Despite our efforts to protect our trade secrets, our competitors may discover our trade secrets, either through breach of these agreements,
independent  development  or  publication  of  information  including  our  trade  secrets  in  cases  where  we  do  not  have  proprietary  or  otherwise  protected  rights  at  the  time  of
publication. A competitor’s discovery of our trade secrets would impair our competitive position and have an adverse impact on our business.

Risks related to with commercializing our product candidates

If we do not obtain the necessary U.S. or worldwide regulatory approvals to commercialize pz-cel, we will not be able to sell pz-cel.

If we cannot obtain regulatory approval for pz-cel, we will not be able to generate revenue from this product candidate. As a result, our ability to generate revenue from product
commercialization may be further delayed. We cannot assure you that we will receive the approvals necessary to commercialize pz-cel or any other product candidate we may
develop in the future. In order to obtain FDA approval of pz-cel or any other product candidate requiring FDA approval, we must successfully complete an FDA BLA review.
Obtaining FDA approval of any other product candidate generally requires significant research and testing, referred to as preclinical studies, as well as human tests, referred to
as clinical trials. Satisfaction of the FDA’s regulatory requirements typically takes many years, depends upon the type, complexity and novelty of the product candidate and
requires  substantial  resources  for  research,  development  and  testing.  We  cannot  predict  whether  our  research  and  clinical  approaches  will  result  in  products  that  the  FDA
considers  safe  for  humans  and  effective  for  indicated  uses.  The  FDA  has  substantial  discretion  in  the  product  approval  process  and  may  require  us  to  conduct  additional
preclinical  and  clinical  testing  or  to  perform  post-marketing  studies.  The  approval  process  may  also  be  delayed  by  changes  in  government  regulation,  future  legislation  or
administrative action or changes in FDA policy that occur prior to or during our regulatory review.

Delays in obtaining regulatory approvals may:

● delay commercialization of, and our ability to derive product revenues from, pz-cel or any other product candidate;
● impose costly procedures on us; and
● diminish any competitive advantages that we may otherwise enjoy.

Even if we comply with all FDA requests, the FDA may ultimately reject our BLA. In addition, the FDA could determine that we must test additional subjects or require that
we  conduct  further  studies  with  more  subjects. We  may  never  obtain  regulatory  approval  for  pz-cel,  or  any  other  future  potential  product  candidate.  Failure  to  obtain  FDA
approval  of  any  of  our  product  candidates  will  severely  undermine  our  business  by  leaving  us  without  the  ability  to  generate  additional  accretive  revenues.  There  is  no
guarantee that we will ever be able to develop or acquire other product candidates. In foreign jurisdictions, we must receive approval from the appropriate regulatory authorities
before we can commercialize any products or product candidates outside the U.S. Foreign regulatory approval processes generally include all of the risks and uncertainties
associated with the FDA approval procedures described above. We cannot assure you that we will receive the approvals necessary to commercialize any product candidate for
sale outside the U.S.

Even if we receive regulatory approval for pz-cel, our lead drug candidate, we may not be able to successfully commercialize the product and the revenue that we generate
from its sales, if any, may be limited.

If  approved  for  marketing,  the  commercial  success  of  pz-cel  will  depend  upon  the  product’s  acceptance  by  the  medical  community,  including  physicians,  patients  and
healthcare payors. The degree of market acceptance for our drug candidate will depend on a number of factors, including:

● actual and perceived efficacy and safety of pz-cel;
● relative convenience, dosing burden and ease of administration;
● potential or perceived advantages or disadvantages over alternative treatments;
● potential post-marketing commitments imposed by regulatory authorities, such as patient registries;
● strength of sales, marketing and distribution support;
● price of our future products, both in absolute terms and relative to alternative treatments;
● the effect of current and future healthcare laws on pz-cel; and
● availability of coverage and reimbursement from government and other third party payers.

40

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If our drug candidate is approved but does not achieve an adequate level of acceptance by physicians, healthcare payors and patients, we may not generate sufficient revenue
and we may not be able to achieve or sustain profitability. Our efforts to educate the medical community and third-party payors on the benefits of our drug candidates may
require significant resources and may never be successful.

Our drug candidates are subject to the risks of failure inherent in the development of pharmaceutical products based on new technologies, and our failure to develop safe
and commercially viable drugs would severely limit our ability to become profitable or to achieve significant revenues.

We may be unable to successfully commercialize our product candidates if some or all of our product candidates are found to be unsafe or ineffective or otherwise fail to meet
applicable  regulatory  standards  or  receive  necessary  regulatory  clearances. Additionally,  our  product  candidates  may  be  deemed  too  difficult  to  develop  into  commercially
viable drugs. We may encounter difficulty in manufacturing or marketing our product candidates on a large scale, and proprietary rights of third parties may preclude us from
marketing  our  drug  candidates.  Moreover,  competitors  may  be  able  to  market  superior  or  equivalent  drugs  successfully.  Failure  to  successfully  commercialize  our  product
candidates would have a material adverse effect on our business.

We  may  be  unable  to  successfully  develop,  market,  or  commercialize  our  products  or  our  product  candidates  without  establishing  new  relationships  and  maintaining
current  relationships  and  our  ability  to  successfully  commercialize,  and  market  our  product  candidates  could  be  limited  if  a  number  of  these  existing  relationships  are
terminated.

Our strategy for the research, development and commercialization of our potential pharmaceutical products may require us to enter into various arrangements with corporate
and academic collaborators, licensors, licensees and others, in addition to our existing relationships with other parties. Specifically, we may seek to joint venture, sublicense or
enter into other marketing arrangements with parties that have an established marketing capability, or we may choose to pursue the commercialization of such products on our
own. We may, however, be unable to establish such additional collaborative arrangements, license agreements, or marketing agreements as we may deem necessary to develop,
commercialize and market our potential pharmaceutical products on acceptable terms. Furthermore, since we maintain and establish arrangements or relationships with third
parties, our business may depend upon the successful performance by these third parties of their responsibilities under those arrangements and relationships. If we are unwilling
or unable to perform our obligations under any license or collaboration arrangement, a third party may have the right to terminate such arrangement with us.

We are subject to extensive governmental regulation, which increases our cost of doing business and may affect our ability to commercialize any new products that we may
develop.

The  FDA  and  comparable  agencies  in  foreign  countries  impose  substantial  requirements  upon  the  introduction  of  pharmaceutical  products  through  lengthy  and  detailed
laboratory, preclinical and clinical testing procedures and other costly and time-consuming procedures to establish safety and efficacy. All of our drugs and drug candidates
require receipt and maintenance of governmental approvals for commercialization. Preclinical and clinical trials and manufacturing of our drug candidates will be subject to the
rigorous testing and approval processes of the FDA and corresponding foreign regulatory authorities. Satisfaction of these requirements typically takes a significant number of
years and can vary substantially based upon the type, complexity, and novelty of the product.

Due to the time-consuming and uncertain nature of the drug candidate development process and the governmental approval process described above, we cannot be certain when
we, independently or with our collaborative partners, might submit a BLA for FDA or other regulatory review. Further, our ability to commence and/or complete development
projects  will  be  subject  to  our  ability  to  raise  enough  funds  to  pay  for  the  development  costs  of  these  projects.  Government  regulation  also  affects  the  manufacturing  and
marketing  of  pharmaceutical  products.  Government  regulations  may  delay  marketing  of  our  potential  drugs  for  a  considerable  or  indefinite  period  of  time,  impose  costly
procedural requirements upon our activities and furnish a competitive advantage to larger companies or companies more experienced in regulatory affairs. Delays in obtaining
governmental regulatory approval could adversely affect our marketing as well as our ability to generate significant revenues from commercial sales.

41

 
 
 
 
 
 
 
 
 
 
Our  drug  candidates  may  not  receive  FDA  or  other  regulatory  approvals  on  a  timely  basis  or  at  all.  Moreover,  if  regulatory  approval  of  a  drug  candidate  is  granted,  such
approval may impose limitations on the indicated use for which such drug may be marketed. Even if we obtain initial regulatory approvals for our drug candidates, our drugs
and our manufacturing facilities would be subject to continual review and periodic inspection, and later discovery of previously unknown problems with a drug, manufacturer
or facility may result in restrictions on the marketing or manufacture of such drug, including withdrawal of the drug from the market. The FDA and other regulatory authorities
stringently apply regulatory standards and failure to comply with regulatory standards can, among other things, result in fines, denial or withdrawal of regulatory approvals,
product recalls or seizures, operating restrictions, and criminal prosecution.

We may incur substantial product liability expenses due to the use or misuse of our products for which we may be unable to obtain insurance coverage.

Our  business  exposes  us  to  potential  liability  risks  that  are  inherent  in  the  testing,  manufacturing,  and  marketing  of  pharmaceutical  products. These  risks  will  expand  with
respect to our drug candidates, if any, that receive regulatory approval for commercial sale and we may face substantial liability for damages in the event of adverse side effects,
including injury or death, or product defects identified with any of our products that are used in clinical tests or marketed to the public. Product liability actions can also have
regulatory consequences, including the withdrawal of clinical trial participants and potential termination of clinical trial sites or entire clinical programs, and the initiation of
investigations, and enforcement actions by regulators, product recalls, withdrawals, revocation of approvals, or labeling, marketing, or promotional restrictions.

Product liability insurance for the biotechnology industry is generally expensive, if available at all, and as a result, we may be unable to obtain insurance coverage at acceptable
costs or in a sufficient amount in the future, if at all. We may be unable to satisfy any claims for which we may be held liable as a result of the use or misuse of products which
we developed, manufactured, or sold and any such product liability claim could adversely affect our business, operating results, or financial condition.

Intense competition may limit our ability to successfully develop and market commercial products.

The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. Our competitors in the U.S. and elsewhere
are  numerous  and  include,  among  others,  major  multinational  pharmaceutical  and  chemical  companies,  specialized  biotechnology  firms  and  universities  and  other  research
institutions.  Many  of  our  competitors  have  and  employ  greater  financial  and  other  resources,  including  larger  research  and  development,  marketing,  and  manufacturing
organizations. As a result, our competitors may successfully develop technologies and drugs that are more effective or less costly than any that we are developing, which could
render our technology and future products obsolete and noncompetitive.

In  addition,  some  of  our  competitors  have  greater  experience  than  we  do  in  conducting  preclinical  and  clinical  trials  and  obtaining  FDA  and  other  regulatory  approvals.
Accordingly, our competitors may succeed in obtaining FDA or other regulatory approvals for drug candidates more rapidly than we can. Companies that complete clinical
trials, obtain required regulatory agency approvals, and commence commercial sale of their drugs before their competitors may achieve a significant competitive advantage.
Drugs  resulting  from  our  research  and  development  efforts  or  from  our  joint  efforts  with  collaborative  partners  therefore  may  not  be  commercially  competitive  with  our
competitors’ existing products or products under development.

42

 
 
 
 
 
 
 
 
 
Our products and product candidates may face competition sooner than anticipated.

Our products and product candidates may face competition from other products that are the same as or similar to ours. If the FDA or comparable foreign regulatory authorities
approve biosimilar versions of our products or product candidates, or such authorities do not grant our products appropriate or anticipated periods of regulatory exclusivity, the
sales of our products could be adversely affected. Moreover, even if we receive periods of regulatory exclusivity, that exclusivity may not adequately protect us from biosimilar
or other product competition. There may also be changes in regulatory exclusivity policies. For example, there have been efforts to decrease the biologic period of exclusivity to
a shorter timeframe. Future proposed budgets, international trade agreements and other arrangements or proposals may affect periods of exclusivity. If another company pursues
approval of a product that is biosimilar to any biologic product for which we receive FDA approval, we may need to pursue costly and time-consuming patent infringement
actions, which may include certain statutorily specified regulatory steps before an infringement action may be brought. Biosimilar applicants may also be able to bring an action
for declaratory judgment concerning our patents, requiring that we spend time and money defending the action.

Our  ability  to  successfully  develop  and  commercialize  our  drug  candidates  will  substantially  depend  upon  the  availability  of  reimbursement  funds  for  the  costs  of  the
resulting drugs and related treatments.

Market  acceptance  and  sales  of  our  product  candidates  may  depend  on  coverage  and  reimbursement  policies  and  health  care  reform  measures.  Decisions  about  formulary
coverage as well as levels at which government authorities and third-party payors, such as private health insurers and health maintenance organizations, reimburse patients for
the price they pay for our products as well as levels at which these payors pay directly for our products, where applicable, could affect whether we are able to commercialize
these products. We cannot be sure that reimbursement will be available for any of these products. Also, we cannot be sure that coverage or reimbursement amounts will not
reduce the demand for, or the price of, our products. We have not commenced efforts to have our product candidates reimbursed by the government or third-party payors. If
coverage and reimbursement are not available or are available only at limited levels, we may not be able to commercialize our products. In recent years, officials have made
numerous proposals to change the health care system in the U.S. These proposals include measures that would limit or prohibit payments for certain medical treatments or
subject the pricing of drugs to government control. In addition, in many foreign countries, particularly the countries of the European Union, the pricing of prescription drugs is
subject to government control. If our products are or become subject to government regulation that limits or prohibits payment for our products, or that subjects the price of our
products to governmental control, we may not be able to generate revenue, attain profitability or commercialize our products.

As a result of legislative proposals and the trend towards managed health care in the U.S., third-party payors are increasingly attempting to contain health care costs by limiting
both coverage and the level of reimbursement of new drugs. They may also impose strict prior authorization requirements and/or refuse to provide any coverage of uses of
approved products for medical indications other than those for which the FDA has granted market approvals. As a result, significant uncertainty exists as to whether and how
much third-party payors will reimburse patients for their use of newly approved drugs, which in turn will put pressure on the pricing of drugs.

The market may not accept any pharmaceutical products that we develop, thereby materially impairing our ability to generate revenue from such products.

The products that we are attempting to develop may compete with drugs manufactured and marketed by other pharmaceutical companies. The degree of market acceptance of
any drugs developed by us will depend on a number of factors, including the establishment and demonstration of the clinical efficacy and safety of our drug candidates, the
potential advantage of our drug candidates over existing therapies and the reimbursement policies of government and third-party payors. Physicians, patients, or the medical
community in general may not accept or use any drugs that we may develop independently or with our collaborative partners and if they do not, our business could suffer.

43

 
 
 
 
 
 
 
 
 
Adverse public perception of gene therapy products may negatively affect demand for, or regulatory approval of, our product candidates.

Our product candidates involve altering genes, and the clinical and commercial success of our product candidates will depend in part on public acceptance of the use of gene
altering therapies for the treatment of genetic diseases. Public attitude may be influenced by claims that gene therapy is unsafe, unethical, or immoral, and, as a result, our
product candidates may not gain the acceptance of the public or the medical community. Negative public reaction to gene therapy in general could result in greater government
regulation and stricter labeling requirements of gene therapy products, including any of our product candidates, and could cause a decrease in the demand for any products we
may develop. Adverse public opinion also may adversely affect our ability to enroll patients in clinical trials.

Healthcare reform measures could hinder or prevent our product candidates’ commercial success.

Any government-adopted reform measures could adversely affect the pricing of healthcare products and services in the U.S. or internationally and the amount of reimbursement
available  from  governmental  agencies  or  other  third-party  payors.  The  continuing  efforts  of  the  U.S.  and  foreign  governments,  insurance  companies,  managed  care
organizations and other payors of health care services to contain or reduce health care costs may adversely affect our ability to set prices for our products which we believe are
fair, restrict coverage and reimbursement, or require payment of increased rebates and our ability to generate revenues and achieve and maintain profitability.

New laws, regulations and judicial decisions, or new interpretations of existing laws, regulations, and decisions, which relate to healthcare availability, methods of delivery or
payment for products and services, or sales, marketing, or pricing, may limit our potential revenue, and we may need to revise our research and development programs. The
pricing and reimbursement environment may change in the future and become more challenging due to several reasons including new healthcare legislation or regulation and
fiscal challenges faced by government health administration authorities. Specifically, in both the U.S. and some foreign jurisdictions, there have been a number of legislative
and regulatory proposals to change the health care system in ways that could affect our ability to sell our products profitably.

We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United
States or abroad.

We  may  be  subject,  directly  or  indirectly,  to  federal,  state,  and  foreign  healthcare  laws  and  regulations,  including  fraud  and  abuse  laws,  false  claims  laws  and  health
information privacy and security laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

If  we  obtain  FDA  approval  for  any  of  our  product  candidates  and  begin  commercializing  those  products  in  the  United  States,  our  operations  will  be  directly,  or  indirectly
through our prescribers, customers, and purchasers, subject to various federal and state laws and regulations, including, without limitation, the federal Anti-Kickback Statute,
the federal civil and criminal false claims act, the civil monetary penalties statute, HIPAA, and the Physician Payments Sunshine Act and regulations. These laws are further
described in the U.S. Biologic Products Development Process section of this annual report. These laws will impact, among other things, our proposed sales, marketing, and
educational programs. In addition, we may be subject to data privacy laws by both the federal government and the states in which we conduct our business. Failure to comply
with these laws could result in penalties, including civil and criminal penalties, damages, fines, the curtailment or restructuring of operations, the exclusion from participation in
federal and state healthcare programs, debarment from government contracting or refusal of orders under existing contracts, corporate integrity agreements or consent decrees,
disgorgement,  contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings,  and  imprisonment.  Furthermore,  efforts  to  ensure  that  business  activities  and
business arrangements comply with applicable healthcare laws and regulations can be costly. Comparable laws and regulations apply internationally.

44

 
 
 
 
 
 
 
 
 
 
We are subject to extensive laws and regulations related to data privacy, and our failure to comply with these laws and regulations could harm our business.

Numerous foreign, federal, and state laws and regulations govern collection, dissemination, use and confidentiality of personally identifiable health information, including state
privacy  and  confidentiality  laws  (including  state  laws  requiring  disclosure  of  breaches),  HIPAA  and  the  European  Union’s  General  Data  Protection  Regulation  (“GDPR”).
These laws and regulations are increasing in complexity and number and may change frequently and sometimes conflict.

HIPAA  establishes  a  set  of  national  privacy  and  security  standards  for  the  protection  of  individually  identifiable  health  information,  including  protected  health  information
(“PHI”),  by  health  plans,  certain  healthcare  clearinghouses  and  healthcare  providers  that  submit  certain  covered  transactions  electronically,  or  covered  entities,  and  their
“business  associates,”  which  are  persons  or  entities  that  perform  certain  services  for,  or  on  behalf  of,  a  covered  entity  that  involve  creating,  receiving,  maintaining  or
transmitting PHI. While we are not currently a covered entity or business associate under HIPAA, we may receive identifiable information from these entities. Failure to protect
this information properly could subject us to HIPAA’s criminal penalties, which may include fines up to $250,000 per violation and/or imprisonment.

GDPR imposes numerous requirements on entities that process personal data in the context of an establishment in the European Economic Area (“EEA”) or that process the
personal  data  of  data  subjects  who  are  located  in  the  EEA. These  requirements  include,  for  example,  establishing  a  basis  for  processing,  providing  notice  to  data  subjects,
developing procedures to vindicate expanded data subject rights, implementing appropriate technical and organizational measures to safeguard personal data, and complying
with restrictions on the cross-border transfer of personal data from the EEA to countries that the European Union does not consider to have in place adequate data protection
legislation, such as the United States. GDPR additionally establishes heightened obligations for entities that process “special categories” of personal data, such as health data.
Nearly all clinical trials involve the processing of these “special categories” of personal data, and thus processing of personal data collected during the course of clinical trials is
subject to heightened protections under GDPR.

Moreover, California adopted the California Consumer Privacy Act of 2018 (“CCPA”), which went into effect in January 2020. The CCPA has been characterized as the first
“GDPR-like” privacy statute to be enacted in the United States because it mirrors a number of the key provisions of the GDPR. The CCPA establishes a new privacy framework
for  covered  businesses  in  the  State  of  California,  by  creating  an  expanded  definition  of  personal  information,  establishing  new  data  privacy  rights  for  consumers  imposing
special  rules  on  the  collection  of  consumer  data  from  minors,  and  creating  a  new  and  potentially  severe  statutory  damages  framework  for  violations  of  the  CCPA  and  for
businesses that fail to implement reasonable security procedures and practices to prevent data breaches.

The legislative and regulatory landscape for privacy and data security continues to evolve, and there has been an increasing focus on privacy and data security issues which may
affect  our  business.  Failure  to  comply  with  current  and  future  laws  and  regulations  could  result  in  government  enforcement  actions  (including  the  imposition  of  significant
penalties), criminal and/or civil liability for us and our officers and directors, private litigation and/or adverse publicity that negatively affects our business.

Trends toward managed health care, health technology assessment, and downward price pressures on medical products and services may limit our ability to profitably sell
any drugs that we may develop.

Lower prices for pharmaceutical products or reduced profitability may result from:

● third-party-payors’  increasing  challenges  to  the  prices  charged  for  medical  products  and  services,  including  by  limiting  coverage  and  reimbursement  and  requiring

payment of increased manufacturer rebates;

● the trend toward managed health care in the U.S. and the concurrent growth of Health Maintenance Organizations (“HMOs”) and similar organizations that can control

or significantly influence the purchase of healthcare services and products; and

● state, federal, and foreign legislative proposals to control drug prices, reform healthcare or reduce government insurance programs.

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The  cost  containment  measures  that  healthcare  providers  are  instituting,  including  practice  protocols  and  guidelines  and  clinical  pathways,  and  the  effect  of  any  healthcare
reform, could limit our ability to profitably sell any drugs that we may successfully develop. Moreover, any future legislation or regulation, if any, relating to the healthcare
industry or third-party coverage and reimbursement, may cause our business to suffer.

Risks related to our intellectual property

Our rights to develop and commercialize our product candidates are subject to, in part, the terms and conditions of licenses granted to us by others.

We rely upon licenses to certain patent rights and proprietary technology from third parties that are important or necessary to the development of our technology and products,
including  technology  related  to  our  manufacturing  process  and  our  product  candidates.  These  and  other  licenses  may  not  provide  exclusive  rights  to  use  such  intellectual
property and technology in all relevant fields of use and in all territories in which we may wish to develop or commercialize our technology and products in the future. As a
result, we may not be able to prevent competitors from developing and commercializing competitive products in territories included in all of our licenses. These licenses may
also require us to grant back certain rights to licensors and to pay certain amounts relating to sublicensing patent and other rights under the agreement.

In some circumstances, particularly in-licenses with academic institutions, we may not have the right to control the preparation, filing and prosecution of patent applications, or
to maintain the patents, covering in-licensed technologies. Therefore, in those cases we cannot be certain that these patents and applications will be prosecuted, maintained and
enforced in a manner consistent with the best interests of our business. If our licensors fail to maintain such patents, or lose rights to those patents or patent applications, the
rights we have licensed may be reduced or eliminated and our right to develop and commercialize any of our products that are the subject of such licensed rights could be
adversely affected. In certain circumstances, we have or may license technology from third parties on a non-exclusive basis. In such instances, other licensees may have the
right to enforce our licensed patents in their respective fields, without our oversight or control. Those other licensees may choose to enforce our licensed patents in a way that
harms our interest, for example, by advocating for claim interpretations or agreeing on invalidity positions that conflict with our positions or our interest. In addition to the
foregoing, the risks associated with patent rights that we license from third parties will also apply to patent rights we may own in the future.

Further, in many of our license agreements we are responsible for bringing any actions against any third party for infringing the patents we have licensed. Certain of our license
agreements  also  require  us  to  meet  development  milestones  to  maintain  the  license,  including  establishing  a  set  timeline  for  developing  and  commercializing  products  and
minimum  yearly  diligence  obligations  in  developing  and  commercializing  the  product.  Disputes  may  arise  regarding  intellectual  property  subject  to  a  licensing  agreement,
including:

● the scope of rights granted under the license agreement and other interpretation-related issues;
● the extent to which our technology and processes infringe intellectual property rights of the licensor that are not subject to the licensing agreement;
● the sublicensing of patent and other rights under our collaborative development relationships;
● our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
● the inventorship or ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and
● the priority of invention of patented technology.

If any dispute over in-licensed intellectual property prevents or impairs our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to
successfully develop and commercialize the affected product candidates.

If we fail to comply with our obligations under these license agreements, or we are subject to a bankruptcy, the licensor may have the right to terminate the license, in which
event  we  would  not  be  able  to  develop,  manufacture,  or  market  products  covered  by  the  license  or  may  face  other  penalties  under  the  agreements.  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. It is possible that such termination may occur even if
we believe that we have complied with our obligations under a license agreement, if a dispute arises between us and a licensor.

Furthermore, to the extent that the research resulting in certain of our licensed patent rights and technology was funded by the U.S. government, the government may have
certain rights, or march-in rights, to such patent rights and technology. When new technologies are developed with U.S. government funding, the U.S. government generally
obtains certain rights in any resulting patents, including a non-exclusive, royalty-free license authorizing the U.S. government, or a third party on its behalf, to use the invention
for non-commercial purposes. These rights may permit the government to disclose our confidential information to third parties and to exercise march-in rights to use or allow
third parties to use our licensed technology. The U.S. government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical
application  of  the  government-funded  technology,  because  action  is  necessary  to  alleviate  health  or  safety  needs,  to  meet  requirements  of  federal  regulations  or  to  give
preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United
States. Any exercise by the government, or a third party on its behalf, of such rights could harm our competitive position, business, financial condition, results of operations and
prospects.

If we are unable to obtain and maintain patent protection for our product candidates and technology, or if the scope of the patent protection obtained is not sufficiently
broad, our competitors could develop and commercialize products and technology similar or identical to ours, and our ability to successfully commercialize our products
and technology may be adversely affected.

Our  success  depends,  in  large  part,  on  our  and  our  licensors’  ability  to  obtain  and  maintain  patent  protection  in  the  United  States  and  other  countries  with  respect  to  our
proprietary product candidates and manufacturing technology. We and our licensors have sought, and we intend to seek in the future, to protect our proprietary positions by
filing patent applications in the United States and abroad related to many of our novel technologies and product candidates that are important to our business.

The patent prosecution process is expensive, time-consuming and complex, and we may not have and may not in the future be able to file, prosecute, maintain, enforce, or
license all necessary or desirable patent applications at a reasonable cost or in a timely manner. For example, in some cases, the work of certain academic researchers in the
gene therapy field has entered the public domain, which may compromise our ability to obtain patent protection for certain inventions related to or building upon such prior
work. Consequently, we will not be able to obtain any such patents to prevent others from using our technology for, and developing and marketing competing products to treat,
these indications. 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.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has, in recent years, been
the subject of much litigation. As a result, the issuance, scope, validity, enforceability, and commercial value of our and our licensors’ patent rights are highly uncertain. Our
pending  and  future  patent  applications  may  not  result  in  patents  being  issued  which  protect  our  technology  or  product  candidates  or  which  effectively  prevent  others  from
commercializing  competitive  technologies  and  product  candidates.  In  particular,  during  prosecution  of  any  patent  application,  the  issuance  of  any  patents  based  on  the
application may depend upon our ability to generate additional preclinical or clinical data that support the patentability of our proposed claims. We may not be able to generate
sufficient additional data on a timely basis, or at all. 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 and our licensors’ patent protection.

47

 
 
 
 
 
 
 
 
We may not be aware of all third-party intellectual property rights potentially relating to our product candidates. Publications of discoveries in the scientific literature often lag
the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing or, in some cases, not at all.

Therefore, we cannot be certain that we were the first to make the inventions claimed in any owned or any licensed patents or pending patent applications, or that we were the
first  to  file  for  patent  protection  of  such  inventions.  Databases  for  patents  and  publications,  and  methods  for  searching  them,  are  inherently  limited,  so  it  is  not  practical  to
review and know the full scope of all issued and pending patent applications. As a result, the issuance, scope, validity, enforceability, and commercial value of our and our
licensed patent rights are uncertain.

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

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or patent offices in the United
States and abroad. Such challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated, or held unenforceable, which could limit our ability to stop
others  from  using  or  commercializing  similar  or  identical  technology  and  products,  or  limit  the  duration  of  the  patent  protection  of  our  technology  and  product  candidates.
Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or
shortly  after  such  candidates  are  commercialized. As  a  result,  our  intellectual  property  may  not  provide  us  with  sufficient  rights  to  exclude  others  from  commercializing
products similar or identical to ours.

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

The  agreements  under  which  we  currently  license  intellectual  property  or  technology  from  third  parties  are  complex,  and  certain  provisions  in  such  agreements  may  be
susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to
the relevant intellectual property or technology or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could harm our
business, financial condition, results of operations and prospects.

We may not be successful in obtaining necessary rights to our product candidates through acquisitions and in-licenses.

We currently have rights to certain intellectual property, through licenses from third parties, to develop our product candidates. Because our programs may require the use of
proprietary rights held by third parties, the growth of our business likely will depend, in part, on our ability to acquire, in-license or use these proprietary rights. We may be
unable to acquire or in-license any compositions, methods of use, processes, or other intellectual property rights from third parties that we identify as necessary for our product
candidates. The licensing or acquisition of third-party intellectual property rights is a competitive area, and several more established companies may pursue strategies to license
or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to their size,
capital resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or
license  rights  to  us. We  also  may  be  unable  to  license  or  acquire  third-party  intellectual  property  rights  on  terms  that  would  allow  us  to  make  an  appropriate  return  on  our
investment.

48

 
 
 
 
 
 
 
 
 
 
We  sometimes  collaborate  with  non-profit  and  academic  institutions  to  accelerate  our  preclinical  research  or  development  under  written  agreements  with  these  institutions.
Typically, these institutions provide us with an option to negotiate a license to any of the institution’s rights in technology resulting from the collaboration. Regardless of such
an option, we may be unable to negotiate a license within the specified timeframe or under terms that are acceptable to us. If we are unable to do so, the institution may offer
the intellectual property rights to other parties, potentially blocking our ability to develop our program.

If we are unable to successfully obtain rights to required third-party intellectual property rights or maintain the existing intellectual property rights we have, we may be required
to  expend  significant  time  and  resources  to  redesign  our  product  candidates  or  the  methods  for  manufacturing  them  or  to  develop  or  license  replacement  technology,  all  of
which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates, which
could harm our business significantly.

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

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

In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable or that
we elect not to patent, processes for which patents are difficult to enforce and any other elements of our product candidate discovery and development processes that involve
proprietary know-how, information or technology that is not covered by patents. However, trade secrets can be difficult to protect. Some courts inside and outside the United
States are less willing or unwilling to protect trade secrets. We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with
our employees, consultants, scientific advisors, collaborators, contractors, and other third-parties. We cannot guarantee that we have entered into such agreements with each
party that may have or have had access to our trade secrets or proprietary technology and processes. We also seek to preserve the integrity and confidentiality of our data and
trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence in these
individuals, organizations and systems, agreements or security measures may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets
may otherwise become known or be independently discovered by competitors.

49

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

Our commercial success depends upon our ability and the ability of our collaborators to develop, manufacture, market and sell our product candidates and use our proprietary
technologies without infringing the proprietary rights and intellectual property of third parties. The biotechnology and pharmaceutical industries are characterized by extensive
and complex litigation regarding patents and other intellectual property rights. We may become party to, or threatened with, infringement litigation claims regarding our product
candidates and technology, including claims from competitors or from non-practicing entities that have no relevant product revenue and against whom our own patent portfolio
may have no deterrent effect. Moreover, we may become party to, or be threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect
to  our  product  candidates  and  technology,  including  interference  or  derivation  proceedings,  post  grant  review  and  inter  partes  review  before  the  USPTO  or  foreign  patent
offices. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit. There is a risk
that third parties may choose to engage in litigation with us to enforce or to otherwise assert their patent rights against us. Even if we believe such claims are without merit, a
court of competent jurisdiction could hold that these third-party patents are valid, enforceable, and infringed, which could adversely affect our ability to commercialize our
product candidates or any other of our product candidates or technologies covered by the asserted third-party patents. In order to successfully challenge the validity of any such
U.S. patent in federal court, we would need to overcome a statutory presumption of validity. As this burden is a high one requiring us to prove by clear and convincing evidence
the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of any such U.S. patent. Similar challenges
exist in other jurisdictions. If we are found to infringe a third-party’s valid and enforceable intellectual property rights, we could be required to obtain a license from such third-
party  to  continue  developing,  manufacturing,  and  marketing  our  product  candidates  and  technology.  However,  we  may  not  be  able  to  obtain  any  required  license  on
commercially reasonable terms, or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the
same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. We could be forced, including by court order, to cease developing,
manufacturing, and commercializing the infringing technology or product candidates. In addition, we could be found liable for monetary damages, including treble damages
and attorneys’ fees, if we are found to have willfully infringed a patent or other intellectual property right. A finding of infringement could prevent us from manufacturing and
commercializing our product candidates or force us to cease some of our business operations, which could harm our business. In addition, we may be forced to redesign our
product  candidates,  seek  new  regulatory  approvals,  and  indemnify  third  parties  pursuant  to  contractual  agreements.  Claims  that  we  have  misappropriated  the  confidential
information or trade secrets of third parties could have a similar negative impact on our business, reputation, financial condition, results of operations and prospects.

We  may  be  subject  to  claims  asserting  that  our  employees,  consultants,  or  advisors  have  wrongfully  used  or  disclosed  alleged  trade  secrets  of  their  current  or  former
employers or claims asserting ownership of what we regard as our own intellectual property.

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

In  addition,  while  it  is  our  policy  to  require  our  employees  and  contractors  who  may  be  involved  in  the  conception  or  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, conceives or develops intellectual
property that we regard as our own. The assignment of intellectual property rights may not be self-executing or the assignment agreements may be breached, and we may be
forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property.

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. Even if we are
successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to management.

50

 
 
 
 
 
 
 
 
If we do not obtain patent term extension and data exclusivity for our product candidates, our business may be harmed.

Depending upon the timing, duration and specifics of any FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent
term extension (“PTE”) under the Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Amendments”). The Hatch-Waxman Amendments
permit a PTE of up to five years as compensation for patent term lost during the FDA regulatory review process. PTE cannot extend the remaining term of a patent beyond a
total of 14 years from the date of product approval, only one patent may be extended per FDA-approved product, and only those claims covering the approved drug, a method
for using it or a method for manufacturing it may be extended. Further, certain of our licenses currently or in the future may not provide us with the right to control decisions of
the licensor or its other licensees with respect to PTE under the Hatch-Waxman Act. Thus, if one of our important licensed patents is eligible for PTE, and it covers a product of
another licensee in addition to our own product candidate, we may not be able to obtain that extension if the other licensee seeks and obtains that extension first. Moreover, we
may  not  be  granted  an  extension  because  of,  for  example,  failing  to  exercise  due  diligence  during  the  testing  phase  or  regulatory  review  process,  failing  to  apply  within
applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements, or the applicable time-period or the scope of
patent protection afforded during any such extension could be less than we request. If we are unable to obtain PTE or the duration of any such extension is less than we request,
the period during which we will have the right to exclusively market our product may be shortened and our competitors may obtain approval of competing products following
our patent expiration, and our revenue could be materially reduced.

Risks related to our financial condition and capital requirements

We have experienced a history of losses; we expect to incur future losses and we may be unable to obtain necessary additional capital to fund operations in the future.

We have recorded minimal revenue to date and have incurred an accumulated deficit of $749.5 million through December 31, 2023. The net loss for the year ended December
31,  2023,  was  $54.2  million.  Our  losses  have  resulted  principally  from  costs  incurred  in  research  and  development  activities  related  to  our  efforts  to  develop  clinical  drug
candidates and from the associated administrative costs.

We  require  substantial  capital  for  our  development  programs  and  operating  expenses,  to  pursue  regulatory  clearances  and  to  prosecute  and  defend  our  intellectual  property
rights. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. We anticipate that our expenses will increase substantially
if and as we:

● seek regulatory and marketing approvals for our product candidates that successfully complete clinical studies;
● continue our research and preclinical and clinical development of our product candidates;
● further develop the manufacturing process for our vectors or our product candidates;
● expand the scope of our current clinical studies for our product candidates;
● change or add additional manufacturers or suppliers;
● seek to identify and validate additional product candidates;
● acquire or in-license other product candidates and technologies;
● make milestone or other payments under any license agreements;
● maintain, protect and expand our intellectual property portfolio;
● establish  a  sales,  marketing  and  distribution  infrastructure  in  the  United  States  and  Europe  to  commercialize  any  products  for  which  we  may  obtain  marketing

approval;

● attract and retain skilled personnel;
● build  additional  infrastructure  to  support  our  operations  as  a  larger  public  company  and  our  product  development  and  planned  future  commercialization  efforts,

including manufacturing capacity; and

● experience any delays or encounter issues with any of the above.

The net losses we incur may fluctuate significantly from quarter to quarter and year to year, such that a period-to-period comparison of our results of operations may not be a
good indication of our future performance. In any particular quarter or quarters, our operating results could be below the expectations of securities analysts or investors, which
could cause our stock price to decline.

51

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
As of December 31, 2023, our cash, cash equivalents, restricted cash and short-term investments were $52.6 million. Based upon our existing cash resources and our recently
announced credit facility of up to $50 million, we believe that we have sufficient resources to fund operations through at least the next 12 months from the date of the issuance
of our consolidated financial statements. However, our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional
funds  sooner  than  planned,  through  public  or  private  equity,  government  or  other  third-party  funding,  marketing  and  distribution  arrangements  and  other  collaborations,
strategic alliances and licensing arrangements or a combination of these approaches. In any event, we will require additional capital to obtain potential regulatory approval for,
and to potentially commercialize, our product candidates. Even if we believe we have sufficient funds for our current or future operating plans, we may seek additional capital
if market conditions are favorable or if we have specific strategic objectives.

Any  additional  fundraising  efforts  may  divert  our  management  from  their  day-to-day  activities,  which  may  adversely  affect  our  ability  to  develop  and  commercialize  our
product candidates. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of
any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities, whether common stock, preferred stock or debt, by
us,  or  the  possibility  of  such  issuance,  may  cause  the  market  price  of  our  shares  to  decline.  The  sale  of  additional  equity  or  convertible  securities  would  dilute  all  of  our
stockholders. The incurrence of indebtedness would result in increased fixed payment obligations, and we may be required to agree to certain restrictive covenants, such as
limitations  on  our  ability  to  incur  additional  debt,  limitations  on  our  ability  to  acquire,  sell  or  license  intellectual  property  rights  and  other  operating  restrictions  that  could
adversely impact our ability to conduct our business. We could also be required to seek funds through arrangements with collaborative partners or otherwise at an earlier stage
than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us,
any of which may have a material adverse effect on our business, operating results, and prospects.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay, or discontinue one or more of our research or development programs or
the commercialization of any product candidates or be unable to expand our operations or otherwise capitalize on our business opportunities, as desired, which could materially
affect our business, financial condition, and results of operations.

We do not have significant operating revenue and may never achieve profitability.

To date, we have funded our operations primarily through public offerings of our common stock. Our ability to achieve significant revenue or profitability depends upon our
ability to complete the development of our drug candidates, to develop and obtain patent protection and regulatory approvals for our drug candidates and to manufacture and
commercialize the resulting drugs. We are not expecting any significant revenues in the short-term from our products or product candidates. Furthermore, we may not be able to
ever  successfully  identify,  develop,  commercialize,  patent,  manufacture,  obtain  required  regulatory  approvals  or  market  any  products.  Moreover,  even  if  we  do  identify,
develop,  commercialize,  patent,  manufacture,  or  obtain  required  regulatory  approvals  to  market  additional  products,  we  may  not  generate  revenues  or  royalties  from
commercial  sales  of  these  products  for  a  significant  number  of  years,  if  at  all. Therefore,  our  operations  are  subject  to  all  the  risks  inherent  in  the  establishment  of  a  new
business  enterprise.  In  the  next  couple  of  years,  we  expect  limited  revenues  from  product  sales,  if  any,  and  any  amounts  that  we  receive  under  strategic  partnerships  and
research or drug development collaborations that we may establish and, as a result, we may be unable to achieve or maintain profitability in the future or to achieve significant
revenues in order to fund our operations.

Failure to achieve and maintain effective internal controls could have a material adverse effect on our business.

Effective internal controls are necessary for us to provide reliable financial reports. If we cannot provide reliable financial reports, our operating results could be harmed. All
internal  control  systems,  no  matter  how  well  designed,  have  inherent  limitations.  Therefore,  even  those  systems  determined  to  be  effective  can  provide  only  reasonable
assurance with respect to financial statement preparation and presentation.

52

 
 
 
 
 
 
 
 
 
Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results, or cause us to fail to meet
our  reporting  obligations.  Failure  to  achieve  and  maintain  an  effective  internal  control  environment  could  cause  investors  to  lose  confidence  in  our  reported  financial
information, which could have a material adverse effect on our stock price. Failure to comply with Section 404 of the Sarbanes-Oxley Act could also potentially subject us to
actions or investigations by the SEC or other regulatory authorities.

We expect to continue to need to raise additional capital to operate our business, and our failure to obtain funding when needed or on terms that are favorable to us may
force us to delay, reduce or eliminate our development programs or commercialization efforts.

We may need to raise additional capital to fund our future operations and we cannot be certain that funding will be available to us on acceptable terms on a timely basis, or at
all. We expect to continue to spend substantial amounts on regulatory approval efforts, product development (including commercialization activities), and conducting potential
future pre-clinical or clinical trials for our product candidates. Our ability to raise capital through the sale of securities may be limited by our number of authorized shares of
common stock and various rules of the SEC and the Nasdaq that place limits on the number and dollar amount of securities that we may sell. If we fail to raise additional funds
on acceptable terms or at all, we may be unable to complete planned preclinical and clinical trials, obtain approval of our product candidates from the FDA and other regulatory
authorities,  or  successfully  commercialize  any  of  our  product  candidates.  In  addition,  we  could  be  forced  to  delay,  discontinue,  or  curtail  product  development,  or  forego
licensing in attractive business opportunities. Any additional sources of financing will likely involve the issuance of our equity or debt securities, which will have a dilutive
effect on our stockholders.

Risks related to our common stock

The market price of our common stock may be volatile and adversely affected by several factors.

The market price of our common stock could fluctuate significantly in response to various factors and events, including:

● our ability to integrate operations, technology, products, and services;
● our ability to execute our business plan;
● operating results below expectations;
● announcements concerning product development results, including clinical trial results;
● regulatory or legal developments in the U.S. or EU, including decisions from regulatory agencies relating to our product candidates;
● litigation or public concern about the safety of our potential products;
● our issuance of additional securities, including debt or equity or a combination thereof, which will be necessary to fund our operating expenses;
● announcements of technological innovations or new products by us or our competitors;
● loss of any strategic relationship;
● industry developments, including, without limitation, changes in healthcare policies or practices or third-party reimbursement policies;
● economic and other external factors;
● period-to-period fluctuations in our financial results; and
● whether an active trading market in our common stock develops and is maintained.

In addition, the securities markets have from time-to-time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular
companies. These market fluctuations may also materially and adversely affect the market price of our common stock.

Raising  additional  funds  by  issuing  securities  or  through  licensing  or  lending  arrangements  or  through  our  at-the-market  sale  agreement  may  cause  dilution  to  our
existing stockholders, restrict our operations, or require us to relinquish proprietary rights.

If we raise additional capital by issuing equity securities, the share ownership of existing stockholders will be diluted. Any future debt financing may involve covenants that,
among other restrictions, limit our ability to incur liens or additional debt, pay dividends, redeem, or repurchase our common stock, make certain investments or engage in
certain merger, consolidation, or asset sale transactions. In addition, if we raise additional funds through licensing arrangements or the disposition of any of our assets, it may be
necessary to relinquish potentially valuable rights to our product candidates or grant licenses on terms that are not favorable to us.

The terms of any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities, whether equity or debt, or the possibility
of such issuance, may cause the market price of our shares to decline. We may sell shares or other securities in other offerings, including under our open market sale agreement,
at a price per share that is less than the prices per share paid by other investors, and investors purchasing shares of our common stock, preferred stock or other securities in the
future could have rights superior to existing stockholders. The sale of additional equity or convertible securities would dilute all of our stockholders and the terms of these
securities may include liquidation or other preferences that adversely affect our existing stockholders.

Our ability to use our net operating loss carry forwards may be subject to limitation.

Generally, a change of more than 50% in the ownership of a company’s stock, by value, over a three-year period constitutes an ownership change for U.S. federal income tax
purposes or applicable state tax law. An ownership change may limit our ability to use our net operating loss carryforwards attributable to the period prior to the change. As a
result, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards to offset U.S. federal and state taxable income may become subject to
limitations, which could potentially result in increased future tax liability for us. As of December 31, 2023, we had net operating loss carryforwards aggregating $377.5 million.

Risks related to cybersecurity

Significant  disruptions  of  information  technology  (“IT”)  systems,  breaches  of  data  security,  or  unauthorized  disclosures  of  personal  information  (including  sensitive
personal information) could adversely affect our business and could subject us to liability or reputational damage.

We operate information systems that contain limited amounts of client data. As a routine element of our business, we collect, analyze, and retain data pertaining to the clinical
trials we conduct for our products. Unauthorized third parties could attempt to gain entry to such information systems to steal data or disrupt the systems or for financial gain.
Like other companies we may experience threats and incursions to our data and systems, including malicious software and viruses, phishing, business email compromise and
social engineering attacks or other cyber-attacks. The number and complexity of these threats continue to increase over time.

We  have  implemented  and  maintain  security  systems  measures  and  safeguards,  which  we  believe  to  be  reasonable,  to  protect  our  information  systems  and  confidential
information, including personal information, and that of our customers, clients and suppliers that is held or processed by us, against unauthorized access or disclosure and to
prevent, detect, contain, respond to, and mitigate security-related threats and potential incidents. We undertake ongoing improvements to the security of our systems, connected
devices,  and  information-sharing  products  in  order  to  minimize  potential  vulnerabilities,  in  accordance  with  industry  and  regulatory  standards.  Despite  such  efforts,  our
safeguards may fail, or we may be subject to breaches of our security resulting in unauthorized access to our facilities or information systems and the information we are trying
to protect. Moreover, our business or operations may be affected in the event our customers, clients and suppliers experience data security incidents, cyber-attacks or extended
interruptions of their services or systems.

54

 
 
 
 
 
 
 
 
 
 
 
We are continuously evaluating and, where appropriate, enhancing our IT systems to address our planned growth, including to support our planned manufacturing operations.
There are inherent costs and risks associated with implementing the enhancements to our IT systems, including potential delays in access to, or errors in, critical business and
financial  information,  substantial  capital  expenditures,  additional  administrative  time  and  operating  expenses,  retention  of  sufficiently  skilled  personnel  to  implement  and
operate the enhanced systems, demands on management time, and costs of delays or difficulties in transitioning to the enhanced systems, any of which could harm our business
and results of operations. In addition, the implementation of enhancements to our IT systems may not result in productivity improvements at a level that outweighs the costs of
implementation, or at all.

While we do not believe cybersecurity incidents have resulted in any material impact on our business, operations or financial results or our ability to service our customers or
run our business, past and future incidents resulting in unauthorized access to our facilities or information systems, or those of our suppliers, or accidental loss or disclosure of
proprietary or confidential information about us, our clients or our customers could result in, among other things, a total shutdown of our systems that would disrupt our ability
to conduct business or pay vendors and employees, violations of applicable privacy and other laws, significant legal and financial exposure, damage to our reputation, and a
loss of investor confidence in our security measures. Additional impacts from cybersecurity incidents could include remediation costs to our customers or business partners,
such as liability for stolen assets or information, repairs of system damage, and incentives for continued business; increased cybersecurity protection costs, which may include
the  costs  of  making  organizational  changes,  deploying  additional  personnel,  resources  and  security  technologies,  training  employees,  and  engaging  third-party  experts  and
consultants;  lost  revenue  resulting  from  the  unauthorized  use  of  proprietary  information  or  the  failure  to  retain  or  attract  business  partners  following  an  incident;  increased
insurance premiums; and damage to the Company’s competitiveness, stock price, and long-term shareholder value. In addition, cybersecurity risks and data security incidents
could lead to unfavorable publicity, governmental inquiry and oversight, regulatory actions by federal, state and non-U.S. governmental authorities, litigation by affected parties
and possible financial obligations for damages related to the theft or misuse of such information, any of which could have a material adverse effect on our profitability and cash
flow.

ITEM 1C, Cybersecurity

Cybersecurity Management and Strategy

In the ordinary course of our business, we collect, use, store, and transmit confidential, financial, sensitive, proprietary, personal, and health-related information. The secure
maintenance of this information and our information technology systems is important to our operations and business strategy. To this end, we consider cybersecurity, along with
other significant risks that we face, within our overall enterprise risk management framework, and have implemented processes designed to assess, identify, and manage risks
from potential unauthorized occurrences on or through our information technology systems that may result in adverse effects on the confidentiality, integrity, and availability of
these  systems  and  the  data  residing  therein.  These  processes  are  managed  and  monitored  by  a  dedicated  Director  of  Information  Technology.  Our  processes  include
mechanisms, controls, technologies, and systems designed to prevent or mitigate data loss, theft, misuse, or other security incidents or vulnerabilities affecting the data and
maintain a stable information technology environment. For example, we conduct penetration and vulnerability testing, and data recovery testing on a periodic basis. In addition,
we consult with outside advisors and experts, when appropriate, to assist with assessing, identifying, and managing cybersecurity risks, including to anticipate future threats and
trends,  and  their  impact  on  the  Company’s  risk  environment. We  also  provide  cybersecurity  training  to  our  employees  and  are  formalizing  an  ongoing  information  security
training program for active employees and relevant consultants to address matters such as phishing, email security, and training on data privacy.

55

 
 
 
 
 
 
 
 
 
 
We have not identified any cybersecurity incidents or threats that have materially affected us or are reasonably likely to materially affect us. However, like other companies in
our industry, we and our third-party vendors have from time-to-time experienced threats to and security incidents relating to information systems. Additional information on
cybersecurity risks we face is discussed in Part I, Item 1A, “Risk Factors,” under the heading “Risks related to cybersecurity.”

Governance

Our Director of Information Technology, who reports to our CFO, is responsible for assessing and managing cybersecurity risks. Our Director of Information Technology has
over 25 years of experience managing information technology and cybersecurity. He has a bachelor’s degree in electrical engineering from Wright State University as well as a
master’s degree in business administration from Ashland University. He has certifications from various information technology vendors as well as experience in implementing
security frameworks such as International Organization for Standardization (“ISO”) 27001 and National Institute of Standards and Technology (“NIST”).

We report on our information security program, including the results of periodic testing, to the Audit Committee of the Board of Directors. Our Board’s Audit Committee is
responsible for overseeing our cybersecurity and information security procedures. The Audit Committee reviews management presentations concerning cybersecurity-related
issues, including information security, technology risks, policies, and risk mitigation programs. The Audit Committee reports matters to the Board of Directors as needed. Our
CFO,  with  the  support  of  our  Director  of  Information  Technology  and  third-party  consultants,  assesses  and  manages  cybersecurity  risk,  including  preventing,  mitigating,
detecting, and addressing cybersecurity incidents, if any. Our CFO also works closely with other management positions and external legal counsel to ensure that we understands
our cybersecurity risk management responsibilities.

ITEM 2. PROPERTIES

Our corporate headquarters are located in Cleveland, Ohio, where we currently lease 45,705 square feet of manufacturing, laboratory and office space. That lease expires in
December 2030. We also lease 10,400 square feet of office space located in New York, New York. That lease expires in December 2030 and has been sublet as of December 31,
2023. We believe that our facilities are sufficient to meet our current needs and that suitable space will be available as and when needed for potential commercialization.

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

You should read the following discussion and analysis together with our consolidated financial statements and related notes included in this Form 10-K. This discussion and
analysis  contains  forward-looking  statements,  which  involve  risks  and  uncertainties.  As  a  result  of  many  factors,  such  as  those  described  under  “Forward-Looking
Statements,” “Risk Factors” and elsewhere in this Form 10-K, our actual results may differ materially from those anticipated in these forward-looking statements.

OVERVIEW

Abeona  is  a  clinical-stage  biopharmaceutical  company  developing  cell  and  gene  therapies  for  life-threatening  diseases.  Our  lead  clinical  program  is  pz-cel,  investigational
autologous, COL7A1 gene-corrected epidermal sheets, currently in development for recessive dystrophic epidermolysis bullosa (“RDEB”). We have announced positive data
from  the  VIITAL™  study  evaluating  the  efficacy,  safety  and  tolerability  of  pz-cel.  The  VIITAL™  study  met  both  its  two  co-primary  efficacy  endpoints  demonstrating
statistically  significant,  clinically  meaningful  improvements  in  wound  healing  and  pain  reduction  in  large  chronic  RDEB  wounds.  On  September  25,  2023,  we  submitted  a
Biologics  License Application  (“BLA”)  for  pz-cel  to  the  U.S.  Food  and  Drug Administration  (“FDA”). As  part  of  the  submission,  we  requested  Priority  Review,  which,  if
granted, would shorten the FDA’s review period to six months from the filing acceptance of the BLA instead of ten months under standard review. In November 2023, the FDA
accepted and granted priority review for our BLA for pz-cel. Under the Prescription Drug User Fee Act (“PDUFA”), the FDA has set a target action date of May 25, 2024.

We have continued to prepare our current Good Manufacturing Practices (“cGMP”) commercial facility in Cleveland, Ohio for manufacturing pz-cel drug product to support
our planned commercial launch of pz-cel, if approved. Pz-cel study drug product for all our VIITAL™ study participants has been manufactured at our Cleveland facility. As
part of our commercial planning, we continue to engage with stakeholders across the healthcare system, including public and private payors, and healthcare providers to better
understand  market  access  and  potential  pricing  for  pz-cel.  We  have  also  begun  discussions  with  high  volume  treatment  centers  of  excellence  to  onboard  them  for  pz-cel
application upon potential FDA approval.

Our development portfolio also features adeno-associated virus (“AAV”) based gene therapies designed to treat ophthalmic diseases using the novel AIM™ capsid platform that
we have exclusively licensed from the University of North Carolina at Chapel Hill, and internal AAV vector research programs.

Preclinical Pipeline

Our preclinical programs are investigating the use of novel AAV capsids in AAV-based therapies for serious genetic eye diseases, including ABO-504 for Stargardt disease,
ABO-503  for  X-linked  retinoschisis  (“XLRS”)  and ABO-505  for  autosomal  dominant  optic  atrophy  (“ADOA”).  We  completed  pre-Investigational  New  Drug Application
(“pre-IND”) meetings with the FDA regarding the preclinical development plans and regulatory requirements to support first-in-human trials.

Recent Developments

On January 8, 2024, we entered into a $50 million credit facility with the Avenue Venture Opportunities Fund, L.P. The credit agreement, which has a term of three and a half
years, includes a first tranche of $20 million at closing, a second tranche of $10 million of committed capital, and an additional accordion option to upsize the credit facility by
an additional $20 million upon satisfaction of certain terms and conditions.

Additionally, the Bioresearch Monitoring (“BIMO”) inspection was conducted from January 22, 2024 through January 24, 2024 at our headquarters in Cleveland, Ohio, and
reviewed the conduct and practices that pertain to the clinical studies of pz-cel. The FDA inspector did not issue any observations or FDA Form 483s during the inspection. The
formal report from the FDA regarding the BIMO inspection will be received at a later date.  FDA’s BIMO program is a comprehensive program of on-site inspections, data
audits,  and  remote  regulatory  assessments  designed  to  monitor  all  aspects  of  the  conduct  and  reporting  of  FDA  regulated  research. The  BIMO  program  was  established  to
assure the quality and integrity of data submitted to the agency in support of new product approvals and marketing applications.

Following the BIMO inspection, the BLA mid-cycle review meeting took place on January 25, 2024. The FDA reaffirmed its earlier indication that it does not currently plan to
convene an Advisory Committee for pz-cel. In addition, the FDA advised that Risk Evaluation and Mitigation Strategies (REMS) are not anticipated for the pz-cel application
at  this  time,  though  application  review  is  ongoing,  and  reconfirmed  the  PDUFA  target  action  date  of  May  25,  2024,  on  which  an  approval  decision  on  the  pz-cel  BLA  is
expected.

Subsequent to the mid-cycle review meeting, the FDA completed a Pre-License Inspection (PLI) of our Cleveland, Ohio manufacturing facility related to our BLA for pz-cel.
During the inspection, the FDA reviewed the facilities, systems, and processes at our Cleveland site. The FDA also observed the manufacturing process for pz-cel, as well as
performance  of  in-process  and  release  assays.  The  two-week  PLI,  which  was  conducted  by  five  FDA  inspectors,  concluded  on  March  1,  2024.  Upon  completion  of  the
inspection, a Form 483 was issued with observations related to process controls. On March 15, 2024, we submitted a response to the FDA, outlining already implemented and
ongoing steps toward resolution that follow FDA guidance provided during the audit. In addition, the FDA completed the clinical study site inspections of the two clinical sites
in the U.S. that enrolled subjects in the pivotal Phase 3 VIITAL™ study supporting the pz-cel BLA with no Form 483 observations noted.

License and other revenues for the year ended December 31, 2023 was $3.5 million, as compared to $1.4 million for the same period of 2022. The revenues in both periods
mainly result from clinical milestones achieved under a sublicense agreement we entered into with Taysha Gene Therapies in October 2020 relating to an investigational AAV-
based gene therapy for Rett syndrome. In 2022, there was also $0.3 million in revenue consisting of the recognition of deferred revenue related to grants for the ABO-102 and
ABO-101 development programs.

Royalties

Total royalty expenses were $1.6 million for the year ended December 31, 2023, as compared to $0.4 million for the same period of 2022, an increase of $1.2 million. The
increase in expense was due to royalties owed to our licensors resulting from the milestones due from Taysha related to Rett syndrome.

Research and development

Research  and  development  expenses  include,  but  are  not  limited  to,  payroll  and  personnel  expense,  lab  supplies,  preclinical  and  development  costs,  clinical  trial  costs,
manufacturing and manufacturing facility costs, costs associated with regulatory approvals, depreciation on lab supplies and manufacturing facilities, and consultant-related
expenses.

Total research and development spending for the year ended December 31, 2023 was $31.1 million, as compared to $29.0 million for the same period of 2022, an increase of
$2.1 million. The increase in expenses was primarily due to an $2.2 million increase in salaries and $0.1 million in non-cash stock-based compensation costs due to increased
headcount related to the filing of our BLA.

We expect our research and development activities to continue as we work towards advancing our product candidates towards potential regulatory approval, reflecting costs
associated with the following:

● employee and consultant-related expenses;
● preclinical and developmental costs;
● clinical trial costs;
● the cost of acquiring and manufacturing clinical trial materials; and
● costs associated with regulatory approvals.

General and administrative

General and administrative expenses primarily consist of payroll and personnel costs, office facility costs, public reporting company related costs, professional fees (e.g., legal
expenses), pre-commercial launch activity costs and other general operating expenses not otherwise included in research and development expenses.

Total general and administrative expenses were $19.0 million for the year ended December 31, 2023, as compared to $17.3 million for the same period of 2022, an increase of
$1.7 million. The increase in expenses was primarily due to:

● increased salary and related costs of $1.8 million;
● increased pre-commercial preparation costs of $1.2 million;
● increased non-cash stock-based compensation of $1.6 million; partially offset by
● decreased other costs such as insurance, rent and offering costs of $2.9 million.

Impairment of licensed technology

Impairment of licensed technology was nil for the year ended December 31, 2023, as compared to $1.4 million in the same period of 2022. The licensed technology was for the
ABO-102 and ABO-101 development programs and as a result of our shift in priorities in 2022, we determined the remaining value of the licensed technology had no future
value and thus recorded an impairment charge of $1.4 million for the year ended December 31, 2022.

Loss/(gain) on operating lease right-of-use assets

The gain on operating lease right-of-use assets was $1.1 million for the year ended December 31, 2023, as compared to a loss on operating lease right-of-use assets of $2.5
million in the same period of 2022. The gain on operating lease right-of-use assets for 2023 was related to the termination of our operating leases for office space that we no
longer use, resulting in a gain from the difference between the carrying value of the right-of-use lease assets and the related lease liabilities.

The loss on operating lease right-of-use assets for 2022 was related to a lease for a future manufacturing facility for the ABO-102 and ABO-101 development programs, which,
as a result of our shift in priorities in 2022, we determined the remaining value of the portion of this lease had no future value and thus recorded an impairment charge of $1.6
million for the year ended December 31, 2022. In addition, we sublet a portion of our leased properties which indicated that a portion of the lease had a reduced future value
and thus recorded impairment of $0.9 million for the year ended December 31, 2022.

Impairment of construction-in-progress

Impairment of construction-in-progress was nil for the year ended December 31, 2023, as compared to $1.8 million in the same period of 2022. The construction-in-progress
was for a facility for the ABO-102 and ABO-101 development programs. As a result of our shift in priorities, we determined the remaining value of the construction-in-progress
facility had no future value and thus, we recorded impairment of $1.8 million for the for the year ended December 31, 2022, which was net of a cash refund from the builder of
$1.5 million.

Interest income

Interest income was $2.1 million for the year ended December 31, 2023, as compared to $0.4 million in the same period of 2022. The increase resulted from higher earnings on
short-term investments driven by higher interest rates and increased average short-term investment balances.

Interest expense

Interest expense was $0.4 million for the year ended December 31, 2023, as compared to $0.7 million in the same period of 2022. The decrease results primarily from the $5.0
million settlement payment made in November 2022 of a disputed liability owed to our prior licensor, REGENXBIO, Inc.

Change in fair value of warrant liabilities

The change in fair value of warrant liabilities was a loss of $11.7 million for the year ended December 31, 2023, as compared to a gain of $11.4 million in the same period of
2022.

We issued stock purchase warrants that are required to be classified as a liability and valued at fair market value at each reporting period. The change in the fair value of warrant
liabilities is primarily due to the fluctuation in our stock price year over year and a shorter term.

Other income

Other income was $2.9 million for the year ended December 31, 2023, as compared to $0.1 million in the same period of 2022. The change was primarily a result of $2.1
million in other income related to the impact of the employee retention credit that we submitted for 2020 and 2021.

Net cash used in operating activities was $37.0 million for the year ended December 31, 2023, primarily comprised of our net loss of $54.2 million and increases in operating
assets and liabilities of $1.8 million partially offset by net non-cash charges of $19.0 million. Non-cash charges consisted primarily of $11.7 million of the change in fair value
of warrant liabilities, $4.8 million of stock-based compensation and $2.2 million of depreciation and amortization.

Net cash used in operating activities was $43.5 million for the year ended December 31, 2022, primarily comprised of our net loss of $39.7 million and decrease in operating
assets and liabilities of $5.9 million partially offset by net non-cash charges of $2.1 million.

Investing activities

Net cash provided by investing activities was $0.2 million for the year ended December 31, 2023, primarily comprised of proceeds from maturities of short-term investments of
$51.9 million and proceeds from the disposal of property and equipment of $0.2 million, partially offset by purchases of short-term investments of $51.6 million and capital
expenditures of $0.3 million.

Net cash used in investing activities was $24.0 million for the year ended December 31, 2022, primarily comprised of purchases of short-term investments of $78.2 million and
capital expenditures of $0.1 million, partially offset by proceeds from maturities of short-term investments of $52.6 million and proceeds from the disposal of property and
equipment of $1.7 million.

Financing activities

Net cash provided by financing activities was $37.1 million for the year ended December 31, 2023, primarily comprised of proceeds of $14.4 million from open market sales of
common stock pursuant to the ATM Agreement (as defined below) and net proceeds of $23.0 million from our July 2023 direct placement offering of common stock.

Net cash provided by financing activities was $43.2 million for the year ended December 31, 2022, primarily comprised of proceeds of $12.8 million from open market sales of
common stock pursuant to the ATM Agreement (as defined below) and proceeds of $34.1 million from a private offering of common stock and warrants on November 3, 2022,
partially offset by the proceeds and redemption of our convertible redeemable preferred stock.

We have historically funded our operations primarily through sales of common stock.

Our principal source of liquidity is cash, cash equivalents, restricted cash and short-term investments, collectively referred to as our cash resources. As of December 31, 2023,
our cash resources were $52.6 million. We believe that our current cash and cash equivalents, restricted cash and short-term investments, as well as our credit facility with
Avenue Venture Opportunities Fund, L.P, are sufficient to fund operations through at least the next 12 months from the date of this report on Form 10-K. We may need to secure
additional  funding  to  carry  out  all  of  our  planned  research  and  development  and  potential  commercialization  activities.  If  we  are  unable  to  obtain  additional  financing  or
generate license or product revenue, the lack of liquidity and sufficient capital resources could have a material adverse effect on our future prospects.

We have an open market sale agreement with Jefferies LLC (as amended, the “ATM Agreement”) pursuant to which, we may sell from time to time, through Jefferies LLC,
shares of our common stock for an aggregate sales price of up to $150.0 million. Any sales of shares pursuant to this agreement are made under our effective “shelf” registration
statement on Form S-3 that is on file with and has been declared effective by the SEC. We sold 3,659,882 shares of our common stock under the ATM Agreement and received
$14.4 million of net proceeds during the year ended December 31, 2023. We sold 3,479,016 shares of our common stock under the ATM Agreement and received $12.8 million
of net proceeds during the year ended December 31, 2022. Subsequent to December 31, 2023 and through March 1, 2024, we sold 724,659 shares of our common stock under
the ATM Agreement resulting in $5.3 million in net proceeds.

Since our inception, we have incurred negative cash flows from operations and have expended, and expect to continue to expend, substantial funds to complete our planned
product development and potential commercialization efforts. We have not been profitable since inception and to date have received limited revenues from the sale of products
or licenses. We expect to incur losses for the next several years as we continue to invest in commercialization, product research and development, preclinical studies, clinical
trials, and regulatory compliance and cannot provide assurance that we will ever be able to generate sufficient product sales or royalty revenue to achieve profitability on a
sustained basis, or at all.

If we raise additional funds by selling additional equity securities, the relative equity ownership of our existing investors will be diluted, and the new investors could obtain
terms more favorable than previous investors. If we raise additional funds through collaborations, strategic alliances, or licensing arrangements with third parties, we may have
to relinquish valuable rights to our technologies, future revenue streams, research programs, or product candidates or grant licenses on terms that may not be favorable to us. If
we are unable to raise additional funds through equity or debt financing when needed, we may be required to delay, limit, or terminate our product development programs or
any future commercialization efforts or grant rights to develop and market product candidates to third parties that we would otherwise prefer to develop and market ourselves.

Our future capital requirements and adequacy of available funds depend on many factors, including:

● the successful development, regulatory approval and commercialization of our cell and gene therapy and other product candidates;
● the ability to establish and maintain collaborative arrangements with corporate partners for the research, development, and commercialization of products;
● continued scientific progress in our research and development programs;
● the magnitude, scope and results of preclinical testing and clinical trials;
● the costs involved in filing, prosecuting, and enforcing patent claims;
● the costs involved in conducting clinical trials;
● competing technological developments;
● the cost of manufacturing and scale-up;
● the ability to establish and maintain effective commercialization arrangements and activities; and
● the successful outcome of our regulatory filings.

Due  to  uncertainties  and  certain  of  the  risks  described  above,  our  ability  to  successfully  commercialize  our  product  candidates,  our  ability  to  obtain  applicable  regulatory
approval  to  market  our  product  candidates,  our  ability  to  obtain  necessary  additional  capital  to  fund  operations  in  the  future,  our  ability  to  successfully  manufacture  our
products  and  our  product  candidates  in  clinical  quantities  or  for  commercial  purposes,  government  regulation  to  which  we  are  subject,  the  uncertainty  associated  with
preclinical and clinical testing, intense competition that we face, the potential necessity of licensing technology from third parties and protection of our intellectual property, it
is not possible to reliably predict future spending or time to completion by project or product category or the period in which material net cash inflows from significant projects
are expected to commence. If we are unable to timely complete a particular project, our research and development efforts could be delayed or reduced, our business could suffer
depending on the significance of the project and we might need to raise additional capital to fund operations, as discussed in the risks above.

We plan to continue our policy of investing any available funds in suitable certificates of deposit, money market funds, government securities and investment-grade, interest-
bearing securities. We do not invest in derivative financial instruments.

Contractual Obligations

We  enter  into  agreements  in  the  normal  course  of  business  with  clinical  research  organizations  for  clinical  trials  and  clinical  manufacturing  organizations  for  supply
manufacturing and with vendors for preclinical research studies and other services and products for operating purposes. These contractual obligations are cancelable at any time
by us, generally upon prior written notice to the vendor, and are thus not included in the contractual obligations table.

Operating lease amounts represent future minimum lease payments under our non-cancelable operating lease agreements. The minimum lease payments above do not include
any related common area maintenance charges or real estate taxes.

On November 12, 2021, we entered into a Settlement Agreement with REGENXBIO to resolve all current disputes between the parties including the aforementioned AAA
arbitration and New York State Supreme Court action. In accordance with the Settlement Agreement, we agreed to pay REGENXBIO a total of $30 million, payable as follows:
(1)  $20  million  payable  that  was  paid  in  2021  after  execution  of  the  Settlement Agreement,  (2)  $5  million  on  the  first  anniversary  of  the  effective  date  of  the  Settlement
Agreement  that  was  paid  in  2022,  and  (3)  $5  million  upon  the  earlier  of:  (i)  the  third  anniversary  of  the  effective  date  of  the  Settlement Agreement  or  (ii)  the  closing  of  a
Strategic Transaction, as defined in the Settlement Agreement. As of December 31, 2023, we have recorded the payable to licensor in the contractual obligations as the one
remaining payment due to REGENXBIO under the Settlement Agreement.

64

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  addition,  we  are  also  party  to  other  license  agreements,  which  include  contingent  payments.  However,  contingent  payments  related  to  these  license  agreements  are  not
disclosed as the satisfaction of these contingent payments is uncertain as of December 31, 2023 and, if satisfied, the timing of payment for these amounts was not reasonably
estimable as of December 31, 2023. Commitments related to the license agreements include contingent payments that will become payable if and when certain development,
regulatory and commercial milestones are achieved. During the next 12 months, certain contingent payments could become due upon potential BLA approval and sales of pz-
cel related to such license agreements.

Critical Accounting Estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates
and assumptions that affect the reported amounts and related disclosures in the financial statements. Management considers an accounting estimate to be critical if:

● it requires assumptions to be made that were uncertain at the time the estimate was made, and
● changes in the estimate or different estimates that could have been selected could have a material impact in our results of operations or financial condition.

While we base our estimates and judgments on our experience and on various other factors that we believe to be reasonable under the circumstances, actual results could differ
from those estimates and the differences could be material.

While  our  significant  accounting  policies  are  described  in  greater  detail  in  Note  1  to  our  consolidated  financial  statements  appearing  elsewhere  in  this Annual  Report,  we
believe that the following accounting policies are the most critical to the judgements and estimates used in the preparation of our consolidated financial statements.

Leases

We account for leases pursuant to ASC 842, Leases (“ASC 842”). ASC 842 requires the recognition of lease assets and lease liabilities by lessees for those leases classified as
operating leases. We determine if an arrangement is a lease at inception or when amended. Right-of-use lease assets represent our right to use an underlying asset for the lease
term and lease liabilities represent our obligation to make lease payments arising from the lease. The classification of our leases as operating or finance leases along with the
initial measurement and recognition of the associated right-of-use assets and lease liabilities is performed at the lease commencement date or when amended. The measurement
of lease liabilities is based on the present value of future lease payments over the lease term. As our leases do not provide an implicit rate, we use our incremental borrowing
rate based on the information available at the lease commencement date in determining the present value of future lease payments. As we have no external borrowings, the
incremental borrowing rates are determined using information on indicative borrowing rates that would be available to us based on the value, currency and borrowing term
provided by financial institutions, adjusted for company and market specific factors. Although we do not expect our estimates of the incremental borrowing rates to generate
material differences within a reasonable range of sensitivities, judgement is involved in selecting an appropriate rate, and the rate selected for each lease will have an impact on
the value of the lease liability and corresponding right-of-use lease asset in the consolidated balance sheets.

The right-of-use asset is based on the measurement of the lease liability and includes any lease payments made prior to or on lease commencement or lease amendment and
excludes lease incentives and initial direct costs incurred, as applicable. Rent expense for our operating leases is recognized on a straight-line basis over the lease term. We do
not have any leases classified as finance leases.

Our leases do not have significant rent escalation, holidays, concessions, material residual value guarantees, material restrictive covenants or contingent rent provisions. Our
leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs), which are
accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. We have elected the practical
expedient to exclude short-term leases from our right-of-use assets and lease liabilities.

Most leases include one or more options to renew. The exercise of lease renewal options is typically at our sole discretion; therefore, the majority of renewals to extend the
lease terms are not included in our right-of-use assets and lease liabilities as they are not reasonably certain of exercise. We regularly evaluate the renewal options and when
they are reasonably certain of exercise, we include the renewal period in our lease term.

In June 2023, we terminated one of our operating leases for office space. The termination resulted in a gain of $1.1 million for the year ended December 31, 2023, representing
the  difference  between  the  carry  value  of  the  right-of-use  assets  and  the  related  lease  liabilities.  This  gain  is  included  in  loss/(gain)  on  right-of-use  lease  assets  in  the
consolidated statement of operations and comprehensive loss.

65

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In June of 2023, we modified one of our operating leases for office space to add up to 14,032 square feet to our existing facility in Cleveland, Ohio. The lease modification
resulted in the recognition of $0.4 million of additional right-of-use assets and related lease liabilities in our consolidated balance sheet during the year ended December 31,
2023.

On March 31, 2022, we announced that we were pursuing a strategic partner to take over development activities of ABO-102 and we were discontinuing development of ABO-
101. As a result of this shift in priorities, we determined the portion of the lease that was dedicated to the future facility for the ABO-101 and ABO-102 programs had no future
value  and  thus,  we  recorded  an  impairment  charge  of  $1.6  million  for  the  year  ended  December  31,  2022.  In  addition,  we  sublet  a  portion  of  our  leased  properties  which
indicated that a portion of the lease had a reduced future value and thus recorded impairment of $0.9 million for the year ended December 31, 2022. Both impairment charges
are included in loss/(gain) on operating lease right-of-use assets in the consolidated statement of operations and comprehensive loss.

Impairment of Long-Lived Assets

Long-Lived Assets consist of property and equipment, licensed technology, and right-of-use (“ROU”) assets. We test our long-lived assets for impairment on an annual basis, or
when events and circumstances indicate that the carrying value of an asset or group of assets may not be fully recoverable. If indicators are present or changes in circumstance
suggest that impairment may exist. We assess the recoverability of the affected long-lived assets by determining whether the carrying value of such assets can be recovered
through undiscounted future operating cash flows. If the carrying amount is not recoverable, we measure the amount of any impairment by comparing the carrying value of the
asset to the present value of the expected future cash flows associated with the use of the asset. The undiscounted future operating cash flows require considerable judgement
and are sensitive to changes in underlying assumptions such as operating costs related to our current facilities, headcount requirements and our clinical costs. As a result, there
can be no assurance that the estimates and assumptions made for purpose of our impairment determinations would prove to be an accurate predication of the future.

Revenue Recognition

We account for revenue under ASC 606, Revenue from Contracts with Customers, (“ASC 606”). We recognize revenue when our customer obtains control of promised goods or
services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements
that we determine are within the scope of ASC 606, we perform the following five steps: (i) identify the contract(s) with our customer; (ii) identify the performance obligations
in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we
satisfy a performance obligation.

Exclusive Licenses

For licenses that are combined with other performance obligation, we utilize judgment to assess the nature of the combined performance obligation to determine whether the
combined  performance  obligation  is  satisfied  over  time  or  at  a  point  in  time  and,  if  over  time,  the  appropriate  method  of  measuring  progress  for  purposes  of  recognizing
revenue. We  evaluate  the  measure  of  progress  each  reporting  period  and,  if  necessary,  adjust  the  measure  of  performance  and  related  revenue  recognition. The  measure  of
progress,  and  thereby  periods  over  which  revenue  should  be  recognized,  are  subject  to  estimates  by  management  and  may  change  over  the  course  of  the  research  and
development and licensing agreement. Such a change could have a material impact on the amount of revenue we record in future periods.

Milestone Payments

At the inception of each arrangement that includes research or development milestone payments, we evaluate whether the milestones are considered probable of being achieved
and estimate the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant cumulative revenue reversal would not
occur, the associated milestone value is included in the transaction price. An output method is generally used to measure progress toward complete satisfaction of a milestone.
Milestone  payments  that  are  not  within  our  control  or  the  licensee,  such  as  regulatory  approvals,  are  not  considered  probable  of  being  achieved  until  those  approvals  are
received. We evaluate factors such as the scientific, clinical, regulatory, commercial, and other risks that must be overcome to achieve the particular milestone in making this
assessment. There is considerable judgment involved in determining whether it is probable that a significant cumulative revenue reversal would not occur. At the end of each
subsequent reporting period, we re-evaluate the probability of achievement of all milestones subject to constraint and, if necessary, adjust our estimate of the overall transaction
price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and earnings in the period of adjustment.

Sublicense and Inventory Purchase Agreements Relating to CLN1 Disease:

In August 2020, we entered into sublicense and inventory purchase agreements with Taysha Gene Therapies (“Taysha”) relating to a potential gene therapy for CLN1 disease.
Under the sublicense agreement, Taysha received worldwide exclusive rights to intellectual property and know-how relating to the research, development, and manufacture of
the potential gene therapy, which we had referred to as ABO-202. Under the inventory purchase agreement, we sold to Taysha certain inventory and other items related to ABO-
202. We assessed the nature of the promised license to determine whether the license has significant stand-alone functionality and evaluated whether such functionality can be
retained without ongoing activities by us and determined that the license has significant stand-alone functionality. Furthermore, we have no ongoing activities associated with
the license to support or maintain the license’s utility. Based on this, we determined that the pattern of transfer of control of the license to Taysha was at a point in time.

The transaction price of the contract includes (i) $7.0 million of fixed consideration, (ii) up to $26.0 million of variable consideration in the form of event-based milestone
payments,  (iii)  up  to  $30.0  million  of  variable  consideration  in  the  form  of  sales-based  milestone  payments,  and  (iv)  other  royalty-based  payments  based  on  net  sales. The
event-based  milestone  payments  are  based  on  certain  development  and  regulatory  events  occurring. At  inception,  we  evaluated  whether  the  milestone  conditions  had  been
achieved and if it was probable that a significant cumulative revenue reversal would not occur before recognizing the associated revenue and determined that these milestone
payments were not within our control or the licensee’s control, such as regulatory approvals, and were not considered probable of being achieved until those approvals were
received. Accordingly, at inception, we fully constrained the $26.0 million of event-based milestone payments until such time that it is probable that significant cumulative
revenue reversal would not occur. The sales-based milestone payments and other royalty-based payments are based on a level of sales for which the license is deemed to be the
predominant  item  to  which  the  royalties  relate. We  will  recognize  revenue  for  these  payments  at  the  later  of  (i)  when  the  related  sales  occur,  or  (ii)  when  the  performance
obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, we have not recognized any sales-based or royalty revenue
resulting from this licensing arrangement.

There was no revenue recognized under this agreement during the years ended December 31, 2023 and 2022. As of December 31, 2023 and 2022, we have no contract assets or
contract liabilities as a result of this transaction.

Sublicense Agreement Relating to Rett Syndrome:

In October 2020, we entered into a sublicense agreement with Taysha for a gene therapy for Rett syndrome and MECP2 gene constructs and regulation of their expression. The
agreement  grants  Taysha  worldwide  exclusive  rights  to  intellectual  property  developed  by  scientists  at  the  University  of  North  Carolina  at  Chapel  Hill,  the  University  of
Edinburgh and us, and our know-how relating to the research, development, and manufacture of the gene therapy for Rett syndrome and MECP2 gene constructs and regulation
of their expression.

We  assessed  the  nature  of  the  promised  license  to  determine  whether  the  license  has  significant  stand-alone  functionality  and  evaluated  whether  such  functionality  can  be
retained without ongoing activities by us and determined that the license has significant stand-alone functionality. Furthermore, we have no ongoing activities associated with
the license to support or maintain the license’s utility. Based on this, we determined that the pattern of transfer of control of the license to Taysha was at a point in time.

The transaction price of the contract includes (i) $3.0 million of fixed consideration, (ii) up to $26.5 million of variable consideration in the form of event-based milestone
payments,  (iii)  up  to  $30.0  million  of  variable  consideration  in  the  form  of  sales-based  milestone  payments,  and  (iv)  other  royalty-based  payments  based  on  net  sales. The
event-based milestone payments are based on certain development and regulatory events occurring. We evaluated whether the milestone conditions have been achieved and if it
is probable that a significant cumulative revenue reversal would not occur before recognizing the associated revenue. We determined that these milestone payments are not
within our control or the licensee’s control, such as regulatory approvals, and are not considered probable of being achieved until those approvals are received. Accordingly, we
have fully constrained the $26.5 million of event-based milestone payments until such time that it is probable that significant cumulative revenue reversal would not occur. The
sales-based  milestone  payments  and  other  royalty-based  payments  are  based  on  a  level  of  sales  for  which  the  license  is  deemed  to  be  the  predominant  item  to  which  the
royalties relate. We will recognize revenue for these payments at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the
royalty has been allocated has been satisfied or partially satisfied. To date, we have not recognized any sales-based or royalty revenue resulting from this licensing arrangement.

67

 
 
 
 
 
 
 
 
 
 
Under  this  arrangement,  we  recognized  $3.5  million  and  $1.0  million  of  revenue  during  the  years  ended  December  31,  2023  and  2022,  respectively,  which  amount  related
solely to variable consideration. As of December 31, 2023 and 2022, we do not have any contract assets or contract liabilities as a result of this transaction.

Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves
reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service
performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers
invoice  us  in  arrears  for  services  performed,  on  a  pre-determined  schedule  or  when  contractual  milestones  are  met;  however,  some  require  advance  payments.  We  make
estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. There may
be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. In accruing service fees, we estimate
the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of
effort  varies  from  our  estimate,  we  adjust  the  accrual  or  amount  of  prepaid  expense  accordingly. Although  we  do  not  expect  our  estimates  to  be  materially  different  from
amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may
result  in  us  reporting  amounts  that  are  too  high  or  too  low  in  any  particular  period. To  date,  we  have  not  made  any  material  adjustments  to  our  prior  estimates  of  accrued
research and development expenses.

Share-Based Compensation Expense

We account for share-based compensation expense in accordance with ASC 718, Stock Based Compensation. We have share-based compensation plans under which incentive
and qualified stock options and restricted shares may be granted to employees, directors, and consultants. We measure the cost of the employee/director/consultant services
received in exchange for an award of equity instruments based on the fair value for employees and directors and vesting date fair value of the award for consultants. We use the
Black-Scholes option pricing model to determine the fair value of options as of the grant date and the Hull White I lattice model as of any option repricing dates. The model
used to determine the fair value of options includes assumptions for expected volatility, risk-free interest rate, dividend yield and estimated expected term. Expected volatility is
estimated considering the Company’s own historical volatility. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected term of
the stock options. The expected dividend yield is assumed to be zero as we have never paid dividends and have no current plans to pay any dividends on our common stock.
Expected term is estimated using the “simplified” method, as outlined in SEC Staff Accounting Bulletin No. 107, “Share-Based Payment.” We use the closing price of our
common stock as quoted on Nasdaq to determine the fair value of restricted stock. We account for forfeitures as they occur, which may result in the reversal of compensation
costs in subsequent periods as the forfeitures arise.

Stock option-based compensation expense recognized for the years ended December 31, 2023 and 2022 was $1.4 million and $2.0 million, respectively. Restricted stock-based
compensation expense recognized for the years ended December 31, 2023 and 2022 was $3.4 million and $1.1 million, respectively.

Warrants

We  have  issued  warrants  associated  with  capital  raises  from  time  to  time.  We  determine  the  accounting  and  value  of  any  issued  warrants  in  accordance  with  ASC  480,
Distinguishing Liabilities from Equity and ASC 815, Derivatives and Hedging. The first step is to determine if the warrants are to be classified as either a liability or equity
depending on the warrant terms. The second step is to then determine the value of the warrants. We measure the value of any liability classified warrants on their issuance date
based  on  their  fair  value  using  the  Black-Scholes  pricing  model. The  model  used  to  determine  the  fair  value  of  these  warrants  utilizes  certain  unobservable  inputs  and  this
therefore considered a Level 3 fair value measurement. Inputs used in the model include assumptions for expected volatility, risk-free interest rate, dividend yield and estimated
expected term. The liability classified warrants are revalued on each subsequent balance sheet date until such instruments are exercised or expire, with any changes in the fair
value between reporting periods recorded in the consolidated statements of operations and comprehensive loss. Certain inputs used in this Black-Scholes pricing model may
fluctuate in future periods based upon factors that are outside of our control, including a potential change in control. A significant change in one or more of these inputs used in
the calculation of the fair value may cause a significant change to the fair value of our warrant liabilities, which could also result in material non-cash gains or losses being
reported in the Company’s statement of operations. In addition, the inputs we utilized to value our warrant liabilities are highly subjective. The assumptions used in calculating
the fair value of our warrant liabilities represent our best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result,
if factors change and we use different assumptions, the fair value of the warrant liabilities may be materially different in the future.

The change in fair value of warrant liability recognized for the year ended December 31, 2023 resulted in a loss of $11.7 million. The change in fair value of warrant liability
recognized for the year ended December 31, 2022 resulted in a gain of $11.4 million.

Our  management,  with  the  participation  of  our  principal  executive  officer  and  principal  financial  officer,  has  evaluated  the  effectiveness  of  our  disclosure  controls  and
procedures (as defined in Rules 13a- 15(e) and 15d- 15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by
this Annual Report on Form 10-K. Based on such evaluation, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure
controls and procedures were effective.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules
13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officers 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:

● Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

● 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

● Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on

the financial statements.

Under  the  supervision  and  with  the  participation  of  management,  including  our  principal  executive  and  financial  officers,  we  assessed  our  internal  control  over  financial
reporting  as  of  December  31,  2023,  based  on  criteria  for  effective  internal  control  over  financial  reporting  established  in  Internal  Control  —  Integrated  Framework  (2013),
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our management’s assessment of the effectiveness of our internal control over
financial reporting included testing and evaluating the design and operating effectiveness of our internal controls. In our management’s opinion, we have maintained effective
internal control over financial reporting as of December 31, 2023, based on criteria established in the COSO 2013 framework.

Because we are a non-accelerated filer and smaller reporting company, Deloitte & Touche LLP, our independent registered public accounting firm, is not required to attest to or
issue a report on the effectiveness of our internal control over financial reporting.

Inherent Limitations of Internal Controls

Our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures or our internal controls
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.  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, within the Company 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 control. 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 the policies or procedures may deteriorate. Projections of any evaluation of effectiveness to future periods are subject to
the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the 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.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15(d)-15(f) promulgated under the Exchange Act,
during the fourth quarter of 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Abeona Therapeutics Inc

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Abeona Therapeutics Inc (the “Company”) as of December 31, 2023, the related consolidated statements of
operations and comprehensive loss, statement of stockholders’ equity and statement of cash flows for the year ended December 31, 2023, and the related notes (collectively
referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December
31, 2023, and the results of its operations and its cash flows for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United
States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our
audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with
respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange  Commission  and  the
PCAOB.

We  conducted  our  audit  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 audit, 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 audit 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 audit provides 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 a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Direct Placement Offering — Refer to Note 9 to the financial statements

Critical Audit Matter Description

As more fully described in Note 9 to the financial statements, On July 6, 2023, the Company sold 3,284,407 shares of its common stock, and in lieu of shares of common stock,
pre-funded  warrants  exercisable  for  2,919,140  shares  of  common  stock  (the  “2023  Pre-Funded  Warrants”),  to  a  group  of  existing  institutional  investors  for  an  aggregate
purchase price of $25.0 million gross, or $23.0 million net of related costs. The offering price for each share of common stock was $4.03, and the offering price for the 2023
Pre-Funded Warrants was $4.0299, which represents the per share offering price for the Company’s common stock less a $0.0001 per share exercise price for each such 2023
Pre-Funded  Warrant.  The  2023  Pre-Funded  Warrants  are  immediately  exercisable  at  a  nominal  exercise  price  of  $0.0001  per  share  and  may  be  exercised  at  any  time.  The
prefunded warrants are classified as equity in accordance with ASC 815, Derivatives and Hedging, given the prefunded warrants are indexed to the Company’s own shares of
common stock and meet the requirements to be classified in equity.

We identified the assessment of the initial accounting for the Direct Placement Offering, specifically the accounting for the 2023 Pre-Funded Warrants as a critical audit matter
because of the complexity in applying the accounting framework and the significant judgments made by management in the determination of the classification of the 2023 Pre-
Funded Warrants. Auditing these conclusions involved especially subjective judgment and audit effort.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to accounting for the 2023 Pre-Funded Warrants included the following, among others:

● We obtained and read the agreements associated with the Direct Placement Offering, including the related 2023 Pre Funded Warrant agreements, and tested the accuracy

and completeness of the significant terms identified by management for purposes determining the classification and earnings per share treatment.

● With  the  assistance  of  professionals  in  our  firm  having  expertise  in  the  accounting  treatment  for  equity  instruments,  including  warrants,  we  evaluated  the  Company’s
conclusions  regarding  the  accounting  treatment  applied  to  the  2023  Pre-Funded Warrants,  including  the  classification  of  warrants  as  equity  and  the  treatment  of  shares
associated with the 2023 Pre-Funded Warrants within weighted average number of shares of common stock outstanding.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders
Abeona Therapeutics Inc. and Subsidiaries

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheet  of Abeona  Therapeutics  Inc.  and  Subsidiaries  (the  “Company”)  as  of  December  31,  2022  and  the  related
consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for the year then ended, and the related notes (collectively referred to as the
“financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31,
2022,  and  the  results  of  their  operations  and  their  cash  flows  for  the  years  then  ended,  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of
America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit. We
are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to
the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We  conducted  our  audit  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 audit 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 entity’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit 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 audit 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 audit provides a reasonable basis for our opinion.

Critical Audit Matters

Critical  audit  matters  are  matters  arising  from  the  current  period  audit  of  the  financial  statements  that  were  communicated  or  required  to  be  communicated  to  the  audit
committee  and  that:  (1)  relate  to  accounts  or  disclosures  that  are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective,  or  complex
judgments. We determined that there are no critical audit matters.

We served as the Company’s auditor from 2006 to 2023.

ABEONA THERAPEUTICS INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements

NOTE 1 – NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Background

Abeona Therapeutics Inc. (together with the Company’s subsidiaries, “Abeona” or the “Company”), a Delaware corporation, is a clinical-stage biopharmaceutical company
developing  cell  and  gene  therapies  for  life-threatening  diseases.  The  Company’s  lead  clinical  program  is  for  pz-cel,  an  autologous,  engineered  cell  therapy  currently  in
development  for  recessive  dystrophic  epidermolysis  bullosa  (“RDEB”).  The  Company’s  development  portfolio  also  features  adeno-associated  virus  (“AAV”)-based  gene
therapies designed to treat highly unmet, medically needed ophthalmic diseases using the novel AIM™ capsid platform that the Company has exclusively licensed from the
University of North Carolina at Chapel Hill, and internal AAV vector research programs.

Reverse Stock Split

On June 30, 2022, the Company filed a Certificate of Amendment to the Company’s Restated Certificate of Incorporation with the Secretary of State of the State of Delaware
(the “Certificate of Amendment”), to effectuate a reverse stock split of the Company’s outstanding common stock, par value $0.01 per share, at an exchange ratio of 25-to-1
(the “Reverse Stock Split”). The Reverse Stock Split was effective on July 1, 2022. The number of authorized shares of common stock immediately after the Reverse Stock
Split (“New Common Stock”) remains at 200,000,000 shares. All share and per share information has been retroactively adjusted to give effect to the Reverse Stock Split for all
periods presented, unless otherwise indicated.

As a result of the Reverse Stock Split, every 25 shares of common stock outstanding immediately prior to the effectiveness of the Reverse Stock Split were combined and
converted into one share of New Common Stock without any change in the par value per share. No fractional shares were issued in connection with the Reverse Stock Split.
Stockholders who would otherwise be entitled to a fraction of one share of New Common Stock as a result of the Reverse Stock Split instead received an amount in cash equal
to such fraction multiplied by the closing sale price of Common Stock on the Nasdaq Capital Market on July 1, 2022, as adjusted for the Reverse Stock Split.

Proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all stock options, restricted stock and
warrants outstanding at July 1, 2022, which resulted in a proportional decrease in the number of shares of the Company’s common stock reserved for issuance upon exercise or
vesting of such stock options, restricted stock and warrants, and, in the case of stock options and warrants, a proportional increase in the exercise price of all such stock options
and warrants.

Liquidity

In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, the Company has evaluated whether there are conditions and events, considered in the
aggregate,  that  raise  substantial  doubt  about  the  Company’s  ability  to  continue  as  a  going  concern  within  one  year  after  the  date  the  accompanying  consolidated  financial
statements were issued.

As a biopharmaceutical organization, the Company has devoted substantially all of its resources since inception to research and development activities for pz-cel and other
product candidates, business planning, raising capital, establishing its intellectual property portfolio, acquiring or discovering product candidates, and providing general and
administrative support for these operations. As a result, the Company has incurred significant operating losses and negative cash flows from operations since its inception and
anticipates such losses and negative cash flows will continue for the foreseeable future.

F-7

 
 
 
 
 
 
 
 
 
 
 
 
 
Since  its  inception,  the  Company  has  funded  its  operations  primarily  with  proceeds  from  sales  of  shares  of  its  stock.  The  Company  has  incurred  recurring  losses  since  its
inception, including net losses contributable to Common Shareholders of $54.2 million and $43.5 million for the years ended December 31, 2023 and 2022, respectively. As of
December 31, 2023, the Company had an accumulated deficit of $749.5 million. To date, the Company has not generated any significant revenues and expects to continue to
generate  operating  losses  for  the  foreseeable  future.  As  of  the  issuance  date  of  these  consolidated  financial  statements,  the  Company  expects  that  its  existing  cash,  cash
equivalents, restricted cash and short-term investments of $52.6 million as of December 31, 2023 in addition to the $20 million received in January 2024 as part of a credit
facility with Avenue Venture Opportunities Fund, L.P. (see Footnote 15) and the $5.3 million in net proceeds from the Company’s common stock sales subsequent to December
31, 2023, will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next 12 months from the issuance date of these consolidated
financial statements.

While the Company believes its capital resources are sufficient to fund the Company’s on-going operations for the next 12 months from the issuance date of these consolidated
financial statements, the Company’s liquidity could be materially affected over this period by: (1) its ability to raise additional capital through equity offerings, debt financings,
or  other  non-dilutive  third-party  funding;  (2)  costs  associated  with  new  or  existing  strategic  alliances,  or  licensing  and  collaboration  arrangements;  (3)  negative  regulatory
events or unanticipated costs related to pz-cel; (4) any other unanticipated material negative events or costs. One or more of these events or costs could materially affect the
Company’s liquidity. If the Company is unable to meet its obligations when they become due, the Company may have to delay expenditures, reduce the scope of its research
and development programs, or make significant changes to its operating plan. The accompanying consolidated financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

Summary of Significant Accounting Policies

A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements follows:

Principles of Consolidation

The consolidated financial statements include the financial statements of Abeona Therapeutics Inc. and the Company’s wholly-owned subsidiaries. All intercompany balances
and transactions have been eliminated in consolidation.

Use of Estimates

The  preparation  of  consolidated  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of America  (“U.S.  GAAP”)  requires
management  to  make  estimates  and  assumptions  that  affect  the  reported  amount  of  assets  and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  consolidated
financial statements and the reported amounts of revenue and expenses during the reported period. The Company’s significant estimates include, but are not limited to, fair
value of warrant liabilities, the incremental borrowing rate related to the Company’s operating leases and stock-based compensation. Due to the uncertainty inherent in such
estimates, actual results could differ from these estimates and assumptions.

Cash and Cash Equivalents

The  Company  considers  all  highly  liquid  investments  with  a  maturity  of  three  months  or  less  when  purchased  to  be  cash  equivalents.  The  Company  maintains  deposits
primarily  in  financial  institutions,  which  may  at  times  exceed  amounts  covered  by  insurance  provided  by  the  U.S.  Federal  Deposit  Insurance  Corporation  (“FDIC”).  The
Company has not experienced any losses related to amounts in excess of FDIC limits.

Restricted Cash

Restricted cash serves as collateral for leased office space.

Short-term Investments

Short-term  investments  consist  of  investments  in  U.S.  government,  U.S.  agency  and  U.S.  treasury  securities. The  Company  determines  the  appropriate  classification  of  the
securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date. The Company classifies its short-term investments as
available-for-sale pursuant to Accounting Standards Codification (“ASC”) 320, Investments – Debt and Equity Securities. Investments classified as current have maturities of
less  than  one  year. The  Company  reviews  its  short-term  investments  for  other-than-temporary  impairment  whenever  the  fair  value  of  a  marketable  security  is  less  than  the
amortized cost and evidence indicates that a short-term investment’s carrying amount is not recoverable within a reasonable period of time.

Other Receivables

Other receivables include employee retention credits (“ERC”), sublease rent receivables and other miscellaneous receivables that are expected to be collected within the next
twelve  months. As  of  December  31,  2023  and  December  31,  2022,  the  Company  had  ERC  receivables  of  $2.1  million  and  nil,  respectively  which  was  recorded  in  other
receivables and as a component of other income in the consolidated statements of operations and comprehensive loss.

Property and Equipment

Property and equipment are recorded at cost. Depreciation is provided using the straight-line method over estimated useful lives ranging from three to five years. Leasehold
improvements  are  amortized  over  the  shorter  of  the  asset’s  useful  life  or  the  life  of  the  lease  term  ranging  from  five  to  ten  years.  Expenditures  for  major  renewals  and
betterments that extend the useful lives are capitalized. Expenditures for normal maintenance and repairs are expensed as incurred. The cost of assets sold or abandoned, and the
related accumulated depreciation are eliminated from the accounts and any gains or losses are recognized in the accompanying consolidated statements of operations of the
respective period.

Leases

The Company accounts for leases in accordance with ASC 842, Leases. Right-of-use lease assets represent the Company’s right to use an underlying asset for the lease term
and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The measurement of lease liabilities is based on the present value of
future lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information
available at the lease commencement date in determining the present value of future lease payments. The right-of-use asset is based on the measurement of the lease liability
and includes any lease payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as applicable. Rent expense for the
Company’s operating leases is recognized on a straight-line basis over the lease term. The Company does not have any leases classified as finance leases.

The  Company’s  leases  do  not  have  significant  rent  escalation,  holidays,  concessions,  material  residual  value  guarantees,  material  restrictive  covenants  or  contingent  rent
provisions. The Company’s leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other
maintenance costs), which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all
leases.

Most leases include one or more options to renew. The exercise of lease renewal options is typically at the Company’s sole discretion; therefore, the majority of renewals to
extend the lease terms are not included in the Company’s right-of-use assets and lease liabilities as they are not reasonably certain of exercise. The Company regularly evaluates
the renewal options and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term.

Licensed Technology

The  Company  has  entered  into  agreements  to  license  the  rights  to  certain  technologies. The  Company  records  the  purchase  price  paid  for  the  license,  which  represents  fair
value,  on  its  consolidated  balance  sheet.  Licensed  technology  is  amortized  over  the  life  of  the  patent  or  the  agreement. The  Company  maintains  licensed  technology  on  its
consolidated balance sheet until either the licensed technology agreement underlying it is completed or the asset becomes impaired. When the Company determines that an
asset has become impaired, as discussed below, or the Company abandons a project, the Company writes down the carrying value of the related intangible asset to its fair value
and recognizes an impairment charge in the period in which the impairment occurs.

F-9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Impairment of Long-Lived Assets

Long-lived  assets  consist  of  property  and  equipment,  licensed  technology,  and  right-of-use  assets. The  Company  tests  its  long-lived  assets  for  impairment  when  events  and
circumstances indicate that the carrying value of an asset or group of assets may not be fully recoverable. If indicators are present or changes in circumstance suggest that
impairment may exist, the Company assesses the recoverability of the affected long-lived assets or group of assets by determining whether the carrying value of such assets or
group  of  assets  can  be  recovered  through  undiscounted  future  operating  cash  flows.  If  the  carrying  amount  is  not  recoverable,  the  Company  measures  the  amount  of  any
impairment by comparing the carrying value of the asset or group of assets to its fair value.

Credit Losses

The Company reviews its available-for-sale investments for credit losses on a collective basis by major security type and in line with the Company’s investment policy. As of
December 31, 2023, the Company’s available-for-sale investments were in securities that are issued by the U.S. treasury and U.S. federal agencies, are highly rated, and have a
history of zero credit losses. The Company reviews the credit quality of its accounts receivables by monitoring the aging of its accounts receivable, the history of write offs for
uncollectible accounts, and the credit quality of its significant customers, the current economic environment/macroeconomic trends, supportable forecasts, and other relevant
factors. The Company’s accounts receivable are with customers that do not have a history of uncollectibility nor a history of significantly aged accounts receivables. As of
December 31, 2023, the Company did not recognize a credit loss allowance for its investments or accounts receivable.

Segments

The Company operates in a single segment. The Company’s chief operating decision maker, its Chief Executive Officer, manages the Company’s operations on a consolidated
basis for the purpose of allocating resources.

Revenue Recognition

The Company accounts for contracts with customers in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). ASC 606 applies to all contracts with
customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods
or  services,  in  an  amount  that  reflects  the  consideration  that  the  entity  expects  to  receive  in  exchange  for  those  goods  or  services.  To  determine  revenue  recognition  for
arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the
performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize
revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the
consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of
ASC 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations and assesses whether each promised
good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as)
the performance obligation is satisfied.

The  Company  enters  into  licensing  agreements  that  are  within  the  scope  of ASC  606,  under  which  it  may  exclusively  license  rights  to  research,  develop,  manufacture  and
commercialize  its  product  candidates  to  third  parties.  The  terms  of  these  arrangements  typically  include  payment  to  the  Company  of  one  or  more  of  the  following:  non-
refundable, upfront license fees; reimbursement of certain costs; customer option exercise fees; development, regulatory and commercial milestone payments; and royalties on
net sales of licensed products.

As  part  of  the  accounting  for  these  arrangements,  the  Company  must  use  significant  judgment  to  determine:  (a)  the  number  of  performance  obligations  based  on  the
determination  under  step  (ii)  above;  (b)  the  transaction  price  under  step  (iii)  above;  and  (c)  the  stand-alone  selling  price  for  each  performance  obligation  identified  in  the
contract  for  the  allocation  of  transaction  price  in  step  (iv)  above. The  Company  uses  judgment  to  determine  whether  milestones  or  other  variable  consideration,  except  for
royalties,  should  be  included  in  the  transaction  price  as  described  further  below. The  transaction  price  is  allocated  to  each  performance  obligation  on  a  relative  stand-alone
selling  price  basis,  for  which  the  Company  recognizes  revenue  as  or  when  the  performance  obligations  under  the  contract  are  satisfied. Amounts  received  prior  to  revenue
recognition are recorded as deferred revenue.

F-10

 
 
 
 
 
 
 
 
 
 
 
 
Exclusive Licenses

If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes
revenue from non-refundable, upfront fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. In
assessing  whether  a  performance  obligation  is  distinct  from  the  other  performance  obligations,  the  Company  considers  factors  such  as  the  research,  development,
manufacturing  and  commercialization  capabilities  of  the  collaboration  partner  and  the  availability  of  the  associated  expertise  in  the  general  marketplace.  In  addition,  the
Company  considers  whether  the  collaboration  partner  can  benefit  from  a  performance  obligation  for  its  intended  purpose  without  the  receipt  of  the  remaining  performance
obligation,  whether  the  value  of  the  performance  obligation  is  dependent  on  the  unsatisfied  performance  obligation,  whether  there  are  other  vendors  that  could  provide  the
remaining performance obligation, and whether it is separately identifiable from the remaining performance obligation. For licenses that are combined with other performance
obligation, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied
over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. The Company evaluates the measure of
progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. The measure of progress, and thereby periods over which
revenue  should  be  recognized,  are  subject  to  estimates  by  management  and  may  change  over  the  course  of  the  research  and  development  and  licensing  agreement.  Such  a
change could have a material impact on the amount of revenue the Company records in future periods.

Milestone Payments

At the inception of each arrangement that includes research or development milestone payments, the Company evaluates whether the milestones are considered probable of
being achieved and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant cumulative revenue
reversal  would  not  occur,  the  associated  milestone  value  is  included  in  the  transaction  price.  An  output  method  is  generally  used  to  measure  progress  toward  complete
satisfaction of a milestone. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of
being achieved until those approvals are received. The Company evaluates factors such as the scientific, clinical, regulatory, commercial, and other risks that must be overcome
to  achieve  the  particular  milestone  in  making  this  assessment. There  is  considerable  judgment  involved  in  determining  whether  it  is  probable  that  a  significant  cumulative
revenue  reversal  would  not  occur.  At  the  end  of  each  subsequent  reporting  period,  the  Company  re-evaluates  the  probability  of  achievement  of  all  milestones  subject  to
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 revenue
and earnings in the period of adjustment.

Collaborative Arrangements

The  Company  analyzes  its  collaboration  arrangements  to  assess  whether  such  arrangements  involve  joint  operating  activities  performed  by  parties  that  are  both  active
participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities and therefore within the scope of ASC 808,
Collaborative  Arrangements  (ASC  808).  This  assessment  is  performed  throughout  the  life  of  the  arrangement  based  on  changes  in  the  responsibilities  of  all  parties  in  the
arrangement. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, the Company first determines which elements of the collaboration are
deemed to be within the scope of ASC 808 and which elements of the collaboration are more reflective of a vendor-customer relationship and therefore within the scope of ASC
606.  For  elements  of  collaboration  arrangements  that  are  accounted  for  pursuant  to  ASC  808,  an  appropriate  recognition  method  is  determined  and  applied  consistently,
generally by analogy to ASC 606. Amounts that are owed to collaboration partners are recognized as an offset to collaboration revenue as such amounts are incurred by the
collaboration partner. For those elements of the arrangement that are accounted for pursuant to ASC 606, the Company applies the five-step model described above under ASC
606.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses include, but are not limited to, payroll and personnel expense, lab supplies,
preclinical  and  development  cost,  clinical  trial  expense,  manufacturing,  regulatory,  and  consulting.  The  cost  of  materials  and  equipment  or  facilities  that  are  acquired  for
research and development activities and that have alternative future uses are capitalized when acquired.

General and Administrative Expenses

General  and  administrative  expenses  primarily  consist  of  personnel,  contract  personnel,  personnel-related  expenses  to  support  the  Company’s  administrative  and  operating
activities, facility costs, professional expenses (i.e., legal expenses), investor relations fees and commercial readiness costs.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences
between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards.
Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation
allowance is provided for deferred tax assets to the extent their realization is in doubt.

The Company accounts for uncertain income tax positions in accordance with ASC 740, Income Taxes. Interest costs and penalties related to income taxes are classified as
interest expense and general and administrative costs, respectively, in the consolidated financial statements. For the years ended December 31, 2023 and 2022, the Company did
not  recognize  any  uncertain  tax  positions,  interest  or  penalty  expense  related  to  income  taxes.  It  is  not  reasonably  likely  for  the  amounts  of  unrecognized  tax  benefits  to
significantly increase or decrease within the next 12 months. The Company files U.S. federal and state income tax returns as necessary. The federal return generally has a three-
year statute of limitations and most states have a four-year statute of limitations; however, the taxing authorities are allowed to review the tax year in which the net operating
loss was generated when the loss is utilized on a tax return. The Company currently does not have any open income tax audits.

Net Loss Per Share

Basic  and  diluted  net  loss  per  share  is  computed  by  dividing  net  loss  attributable  to  common  shareholders  by  the  weighted-average  number  of  shares  of  common  stock
outstanding  during  the  period.  The  weighted  average  number  of  shares  of  common  stock  includes  the  weighted  average  effect  of  outstanding  pre-funded  warrants  for  the
purchase of shares of common stock for which the remaining unfunded exercise price is $0.0001 or less per share (Note 9). The Company does not include the potential impact
of dilutive securities in diluted net loss per share, as the impact of these items is anti-dilutive. Potential dilutive securities result from outstanding restricted stock, stock options,
and stock purchase warrants.

The following table sets forth the potential securities that could potentially dilute basic loss per share in the future that were not included in the computation of diluted net loss
per share because to do so would have been anti-dilutive for the periods presented:

9,397,879 
10,455,607 

The  Company  accounts  for  stock-based  compensation  expense  in  accordance  with  ASC  718,  Stock  Based  Compensation.  The  Company  measures  the  cost  of  the
employee/director/consultant services received in exchange for an award of equity instruments based on the grant date fair value for the employees and directors and vesting
date fair value for consultants of the award. The Company uses the Black-Scholes option pricing model to determine the fair value of options on the grant date which includes
assumptions for expected volatility, risk-free interest rate, dividend yield and estimated expected term. The Company uses the closing price of its common stock as quoted on
the  Nasdaq  to  determine  the  fair  value  of  restricted  stock.  The  Company  accounts  for  forfeitures  as  they  occur,  which  may  result  in  the  reversal  of  compensation  costs  in
subsequent periods as the forfeitures arise. The Company estimates the expected term using the “simplified” method, as outlined in SEC Staff Accounting Bulletin No. 107,
“Share-Based Payment.”

Warrants

On  November  3,  2022,  the  Company  issued  warrants  to  purchase  7,609,879  shares  of  common  stock,  with  an  exercise  price  of  $4.75  per  share,  subject  to  customary
adjustments thereunder. On December 17, 2021, the Company issued warrants to purchase 1,788,000 shares of common stock, with an exercise price of $9.75 (post-split) per
share, subject to customary adjustments thereunder. The warrants issued in 2022 and 2021 were determined to be freestanding instruments as they are legally detachable and
separately exercisable from each other and from the common stock issued.

The common stock warrants are accounted for as liabilities in the consolidated balance sheets at their estimated fair value because they are not indexed to the Company’s own
stock. The warrants are revalued on each subsequent balance sheet date until such instruments are exercised or expire, with any changes in the fair value between reporting
periods recorded in the consolidated statements of operations and comprehensive loss.

On July 6, 2023, the Company issued pre-funded warrants to purchase 2,919,140 shares of common stock, with an exercise price of $4.0299 per share. The prefunded warrants
are classified as equity in accordance with ASC 815, Derivatives and Hedging, given the prefunded warrants are indexed to the Company’s own shares of common stock and
meet  the  requirements  to  be  classified  in  equity.  The  prefunded  warrants  were  recorded  at  their  relative  fair  value  at  issuance  in  the  stockholders’  equity  section  of  the
consolidated balance sheet and the prefunded warrants are considered outstanding shares in the basic earnings per share calculation given their nominal exercise price.

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-13 (Topic 326), Financial Instruments—Credit Losses: Measurement of Credit Losses
on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized
cost to be presented at the net amount expected to be collected. The new guidance was effective for the Company on January 1, 2023, and the adoption did not have a material
impact on the Company’s consolidated financial statements.

Recently Issued Accounting Pronouncements

In  December  2023,  the  FASB  issued  ASU  No.  2023-09,  Income  Taxes  (Topic  740):  Improvements  to  Income  Tax  Disclosures.  ASU  2023-09  is  intended  to  enhance  the
transparency and decision usefulness of income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes
paid information. The standard is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted. The Company is currently assessing
the impact that the adoption will have on its consolidated financial statements.

public entity’s reportable segments and requires more enhanced information about a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s
chief operating decision maker uses reported segment profit or loss information in assessing segment performance and allocating resources. The standard is effective for annual
reporting periods beginning after December 15, 2023, and interim periods within years beginning after December 15, 2024, with early adoption permitted. The Company is

As of December 31, 2023, the available-for-sale securities classified as short-term investments mature in one year or less. The Company carries its available-for-sale securities
at  fair  value  in  the  consolidated  balance  sheets.  Unrealized  losses  on  available-for-sale  securities  as  of  December  31,  2023,  were  not  significant  and  were  primarily  due  to
changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. None of the short-term investments have been
in a continuous unrealized loss position for more than 12 months. Accordingly, no other-than-temporary impairment was recorded for the year ended December 31, 2023.

There were no significant realized gains or losses recognized on the sale or maturity of available-for-sale investments during the years ended December 31, 2023 or 2022.

Depreciation and amortization on property and equipment was $2.3 million and $3.1 million for the years ended December 31, 2023 and 2022, respectively. The Company
incurred a loss on disposal of equipment of $47,000 and $0.1 million during the years ended December 31, 2023 and 2022, respectively, which is reflected in other income in
the consolidated statements of operations and comprehensive loss.

On March 31, 2022, the Company announced that it was pursuing a strategic partner to take over development activities of ABO-102 and that it was discontinuing development
of ABO-101. As  a  result,  the  Company  determined  the  construction-in-progress  that  was  dedicated  to  the ABO-101  and ABO-102  programs  had  no  future  value,  and  thus
recorded an impairment charge of $1.8 million for the year ended December 31, 2022, which was net of a cash refund from the builder of $1.5 million.

NOTE 4 – LICENSED TECHNOLOGY

On May 15, 2015, the Company acquired Abeona Therapeutics LLC, which had an exclusive license through Nationwide Children’s Hospital to the AB-101 and AB-102 patent
portfolios for developing treatments for patients with Sanfilippo Syndrome Type B and Sanfilippo Syndrome Type A, respectively. The license was being amortized to expense
over the life of the license of 20 years. On March 31, 2022, the Company announced that it was pursuing a strategic partner to take over development activities of ABO-102 and
that it was discontinuing development of ABO-101. As a result of this shift in priorities, the Company determined the remaining value of the licensed technology had no future
value and thus recorded an impairment charge of $1.4 million for the year ended December 31, 2022. There is no remaining net value of licensed technology as of December
31, 2023 and December 31, 2022.

The  Company  calculates  the  fair  value  of  the  Company’s  assets  and  liabilities  that  qualify  as  financial  instruments  and  includes  additional  information  in  the  notes  to  the
consolidated financial statements when the fair value is different than the carrying value of these financial instruments. The estimated fair value of other receivables, prepaid
expenses and other current assets, other assets, accounts payable, accrued expenses, and payables to licensor approximate their carrying amounts due to the relatively short
maturity of these instruments.

U.S. GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market
for  the  asset  or  liability  in  an  orderly  transaction  between  market  participants  at  the  measurement  date.  This  guidance  establishes  a  three-level  fair  value  hierarchy  that
prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The
three levels of inputs used to measure fair value are as follows:

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

● Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for

identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

● Level  3  -  Unobservable  inputs  that  are  supported  by  little  or  no  market  activity  and  that  are  significant  to  the  fair  value  of  the  assets  and  liabilities. This  includes

certain pricing models, discounted cash flow methodologies and similar valuation techniques that use significant unobservable inputs.

The Company has segregated all financial assets and liabilities that are measured at fair value on a recurring basis (at least annually) into the most appropriate level within the
fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the table below.

The following table provides a summary of financial assets measured at fair value on a recurring and non-recurring basis (in thousands):

As of December 31, 2023 and 2022, the Company had outstanding warrant liabilities related to the 2022 private placement that allow the holders to purchase 7,609,879 shares
of common stock at an exercise price of $4.75 per share. The expiration date for these warrant liabilities is November 2027. As of December 31, 2023 and 2022, the Company
had outstanding warrant liabilities related to the 2021 public offering that allow the holders to purchase 1,788,000 shares of common stock at an exercise price of $9.75 per
share. The expiration date for these warrant liabilities is December 2026. The common stock warrants are not indexed to the Company’s own stock and therefore have been
classified as liabilities at their estimated fair value. Changes in the estimated fair value of the warrant liabilities is recorded as changes in fair value of warrant liabilities in the
consolidated statement of operations and comprehensive loss.

The warrant liabilities are valued using significant inputs not observable in the market. Accordingly, the warrant liability is measured at fair value on a recurring basis using
unobservable inputs and are classified as Level 3 inputs within the fair value hierarchy. Fair value measurements categorized within Level 3 are sensitive to changes in the
assumptions or methodology used to determine fair value and such changes could result in a significant increase or decrease in the fair value. The Company’s valuation of the
common stock warrants utilized the Black-Scholes option-pricing model, which incorporated assumptions and estimates to value the common stock warrants. The Company
assessed these assumptions and estimates at the end of each reporting period.

On November 12, 2021, the Company entered into a settlement agreement (“Settlement Agreement”) with the Company’s prior licensor REGENXBIO Inc. (“REGENXBIO”)
to resolve all existing disputes between the parties. In accordance with the Settlement Agreement, the Company agreed to pay REGENXBIO a total of $30.0 million, payable as
follows: (1) $20.0 million paid in November 2021 after execution of the Settlement Agreement, (2) $5.0 million on the first anniversary of the effective date of the Settlement
Agreement (paid in November 2022), and (3) $5.0 million upon the earlier of (i) the third anniversary of the effective date of the Settlement Agreement or (ii) the closing of a
Strategic Transaction, as defined in the Settlement Agreement.

As of December 31, 2023 and 2022, the Company recorded the payable due to REGENXBIO in the consolidated balance sheet based on the present value of the remaining
payments due to REGENXBIO under the Settlement Agreement using an effective interest rate of 9.6%. The present value of the amount due in November 2024 was $4.6
million and $4.2 million as of December 31, 2023 and 2022, respectively.

The Company leases space under operating leases for administrative, manufacturing and laboratory facilities in Cleveland, Ohio. The Company also leases office space in New
York, New York, that the Company sublets. The Company also leases certain office equipment under operating leases, which have a non-cancelable lease term of less than one
year and the Company has elected the practical expedient to exclude these short-term leases from the Company’s right-of-use assets and lease liabilities.

During 2023, the Company terminated one of its operating leases for office space. The termination resulted in a gain of $1.1 million representing the difference between the
carry value of the right-of-use assets and the related lease liabilities. This gain was recorded in the year ended December 31, 2023, and is included in loss/(gain) on operating
lease right-of-use assets in the consolidated statement of operations and comprehensive loss.

During 2023, the Company modified one of its operating leases for office space to add up to 14,032 square feet to the Company’s existing facility in Cleveland, Ohio. The lease
modification resulted in the recognition of $0.4 million of additional right-of-use assets and related lease liabilities in the Company’s consolidated balance sheet during the year
ended December 31, 2023.

During 2022, the Company announced a strategic partner to take over development activities of ABO-102 and that the Company was discontinuing development of ABO-101.
As a result, the Company determined the portion of the lease that was dedicated to the future facility for the ABO-101 and ABO-102 programs, had no future value and thus,
the Company recorded an impairment charge of $1.6 million for the year ended December 31, 2022 and is included in loss/(gain) on operating lease right-of-use assets in the
consolidated statement of operations and comprehensive loss.

In November 2022, the Company entered into a sublease agreement with an unrelated third party to occupy approximately 5,700 square feet of the Company’s administrative
offices  in  New  York,  New  York.  Because  the  future  sublease  income  under  the  executed  sublease  agreement  is  less  than  the  amount  the  Company  pays  its  landlord,  the
Company recorded an impairment charge of $0.9 million for the year ended December 31, 2022. In April of 2023, the Company entered into a sublease agreement with an
unrelated third party to occupy approximately 4,670 square feet of the Company’s administrative offices in New York, New York. The Company expects to receive $1.1 million
in future sublease income through September 2025 from the two subleases noted above.

Series A and B Convertible Redeemable Preferred Stock

On  May  2,  2022,  the  Company  consummated  an  offering  with  certain  institutional  investors  for  the  private  placement  of  1,000,006  shares  of  the  Company’s  Series  A
Convertible Redeemable Preferred Stock (the “Series A Preferred Stock”) and 250,005 shares of the Company’s Series B Convertible Redeemable Preferred Stock (the “Series
B  Preferred  Stock”  and  together  with  the  Series  A  Preferred  Stock,  the  “Preferred  Stock”).  The  shares,  which  have  since  been  redeemed  in  accordance  with  their  terms
described  below  and  were  thus  no  longer  outstanding  as  of  December  31,  2022,  had  an  aggregated  stated  value  of  $25.0  million.  Each  share  of  the  Preferred  Stock  had  a
purchase price of $19.00, representing an original issue discount of 5% of the stated value. In connection with this offering, the Company had net proceeds of $22.5 million and
recognized a deemed dividend of $3.8 million. In connection with this transaction, the Company placed $26.3 million into an escrow account for any future redemption which
consisted of the gross proceeds of $25.0 million and the redemption value of $1.3 million.

The Preferred Stock was convertible, at the option of the holders and, in certain circumstances, by the Company, into shares of common stock at a conversion price of $11.25
per share. The holders of the Series A Preferred Stock and Series B Preferred Stock had the right to require the Company to redeem their shares of preferred stock for cash at
105%  of  the  stated  value  of  such  shares  commencing  after  the  earlier  of  the  receipt  of  stockholder  approval  of  an  amendment  to  the  Company’s  Restated  Certificate  of
Incorporation to effect a reverse stock split and 60 days after the closing of the issuances of the Series A Preferred Stock and Series B Preferred Stock and until 90 days after
such closing. The Company had the option to redeem the Series A Preferred Stock for cash at 105% of the stated value commencing after the 90th day following the closing of
the  issuance  of  the  Series A  Preferred  Stock,  subject  to  the  holders’  rights  to  convert  the  shares  prior  to  such  redemption. As  a  result,  the  Preferred  Stock  was  recorded
separately from stockholders’ equity because it was redeemable upon the occurrence of redemption events that were considered not solely withing the Company’s control. As
such, during the year ended December 31, 2022, the Company recognized $3.8 million in deemed dividends related to the Preferred Stock in the consolidated statements of
operations and comprehensive loss and the consolidated statements of changes in stockholders’ equity.

On June 17, 2022, the holders of all 1,000,006 shares of Series A Preferred Stock and 250,005 shares of Series B Preferred Stock exercised their right to cause the Company to
redeem all such shares for $26.3 million, which represented a price equal to 105% of the stated value. The redemption of these shares was paid out of the escrow account noted
above.

Common Stock and Warrants

Reverse Stock Split

Effective July 1, 2022, the Company’s stock underwent a 25:1 Reverse Stock Split. The number of authorized shares of common stock immediately after the Reverse Stock
Split remained at 200,000,000 shares.

Public Offerings

On December 21, 2021, the Company closed an underwritten public offering of 1,788,000 post-split shares of common stock at a public offering price of $9.75 post-split per
share and stock purchase warrants to purchase 1,788,000 post-split shares of common stock at an exercise price of $9.75 post-split. The net proceeds to the Company were
$16.0 million, after deducting $1.5 million of underwriting discounts and commissions and offering expenses payable by the Company. The net proceeds were allocated to the
warrant liability as noted below with the remainder of $7.0 million recorded in common stock and additional paid-in capital. In the event of certain fundamental transactions
involving the Company, the holders of the stock purchase warrants may require the Company to make a payment based on a Black-Scholes valuation, using specific inputs that
are  not  considered  indexed  to  the  Company’s  stock  in  accordance  with ASC  815,  Derivatives  and  Hedging  (“ASC  815”). Therefore,  the  Company  accounted  for  the  stock
purchase warrants as liabilities, which were recorded at the closing date fair value of $9.0 million which was based on a Black-Scholes option pricing model. The remainder of
the proceeds were allocated to common stock issued and recorded as a component of equity.

As of December 31, 2023, there were 1,788,000 post-split stock purchase warrants outstanding. These stock purchase warrants expire on December 21, 2026. During such time
as each warrant is outstanding, the holder of the warrant is entitled to participate in any dividends or other distribution of assets along with the holders of shares of common
stock. There was no warrant activity during the year ended December 31, 2023, other than the change in fair value of the warrants.

Open Market Sale Agreement

On August 17, 2018, the Company entered into an open market sale agreement (as amended, the “ATM Agreement”) with Jefferies LLC (“Jefferies”) pursuant to which, the
Company may sell from time to time, through Jefferies, shares of its common stock for an aggregate sales price of up to $150.0 million. Any sales of shares pursuant to this
agreement are made under the Company’s effective “shelf” registration statement on Form S-3 that is on file with and has been declared effective by the SEC. The Company
sold  3,659,882  and  3,479,016  shares  of  its  common  stock  under  the ATM Agreement  during  the  years  ended  December  31,  2023  and  2022,  respectively,  resulting  in  net
proceeds of $14.4 million and $12.8 million during the years ended December 31, 2023 and 2022, respectively. Subsequent to December 31, 2023 and through March 1, 2024,
the Company sold 724,659 shares of its common stock under the ATM Agreement resulting in $5.3 million in net proceeds.

Private Placement Offering

On November 3, 2022, the Company sold 7,065,946 shares of its common stock, and in lieu of shares of common stock, pre-funded warrants exercisable for 543,933 shares of
common stock and accompanying warrants to purchase 7,609,879 shares of its common stock to a group of new and existing institutional investors in a private placement. The
offering price for each share of common stock and accompanying warrant was $4.60, and the offering price for each pre-funded warrant and accompanying warrant was $4.59,
which  equaled  the  offering  price  per  share  of  the  common  stock  and  accompanying  warrant,  less  the  $0.01  per  share  exercise  price  of  each  pre-funded  warrant.  Each
accompanying warrant represents the right to purchase one share of the Company’s common stock at an exercise price of $4.75 per share of common stock. The pre-funded
warrants were exercised in December 2022 and converted to 543,933 shares of commons stock. Total shares sold and converted during the year ended December 31, 2022 were
7,609,879  for  an  aggregate  purchase  price  of  $35.0  million  gross,  or  $32.6  million  net  of  related  costs  of  $1.5  million  which  was  expensed  to  general  and  administrative
expenses and $0.9 million which was recorded as a reduction to additional paid-in-capital. The net proceeds were allocated to the warrant liability as noted below with the
remainder of $12.9 million and $0.1 million recorded in additional paid-in capital and common stock, respectively.

F-21

 
 
 
 
 
 
 
 
 
 
 
 
In the event of certain fundamental transactions involving the Company, the holders of the stock purchase warrants may require the Company to make a payment based on a
Black-Scholes valuation, using specific inputs that are not considered indexed to the Company’s stock in accordance with ASC 815. Therefore, the Company is accounting for
the stock purchase warrants as liabilities. On November 3, 2022, the stock purchase warrants were recorded at the closing date fair value of $22.0 million which was based on a
Black-Scholes option pricing model. The remainder of the proceeds were allocated to common stock issued and recorded as a component of equity.

As of December 31, 2023, there were 7,609,879 warrants outstanding related to this private placement offering. The warrants expire on November 3, 2027. During such time as
each warrant is outstanding, the holder of the warrant is entitled to participate in any dividends or other distribution of assets to holders of shares of common stock. There was
no warrant activity during the year ended December 31, 2023, other than the change in fair value of the warrants.

Direct Placement Offering

On July 6, 2023, the Company sold 3,284,407 shares of its common stock, and in lieu of shares of common stock, pre-funded warrants exercisable for 2,919,140 shares of
common stock (the “2023 Pre-Funded Warrants”), to a group of existing institutional investors for an aggregate purchase price of $25.0 million gross, or $23.0 million net of
related costs. The offering price for each share of common stock was $4.03, and the offering price for the 2023 Pre-Funded Warrants was $4.0299, which represents the per
share  offering  price  for  the  Company’s  common  stock  less  a  $0.0001  per  share  exercise  price  for  each  such  2023  Pre-Funded Warrant. The  2023  Pre-Funded Warrants  are
immediately  exercisable  at  a  nominal  exercise  price  of  $0.0001  per  share,  may  be  exercised  at  any  time  and  do  not  have  an  expiration  date.  None  of  the  2023  Pre-Funded
Warrants  have  been  exercised  as  of  December  31,  2023. The  prefunded  warrants  are  classified  as  equity  in  accordance  with ASC  815,  Derivatives  and  Hedging,  given  the
prefunded warrants are indexed to the Company’s own shares of common stock and meet the requirements to be classified in equity. The prefunded warrants were recorded at
their relative fair value at issuance in the stockholders’ equity section of the consolidated balance sheet and the prefunded warrants are considered outstanding shares in the
basic earnings per share calculation for the year ended December 31, 2023 given their nominal exercise price.

NOTE 10 – STOCK-BASED COMPENSATION

The Company previously granted stock options under its 2005 Equity Incentive Plan (the “2005 Incentive Plan”), under which no further grants can be made. In addition, prior
to May 17, 2023, the Company had previously granted stock options and stock awards under the Abeona Therapeutics Inc. 2015 Equity Incentive Plan (the “2015 Incentive
Plan”). As  of  May  17,  2023,  no  further  grants  can  be  made  under  the  2015  Incentive  Plan.  The  Company  now  grants  stock  options  and  stock  awards  under  the Abeona

Stock Options

The Company estimates the fair value of each option award on the date of grant using the Black-Scholes option-pricing model. The Company then recognize the grant date fair
value of each option as compensation expense ratably using the straight-line attribution method over the service period (generally the vesting period). The Black-Scholes model
incorporates the following assumptions:

● Expected volatility – the Company estimates the volatility of the share price at the date of grant using a “look-back” period which coincides with the expected term,
defined below. The Company believes using a “look-back” period which coincides with the expected term is the most appropriate measure for determining expected
volatility.

● Expected  term  –  the  Company  estimates  the  expected  term  using  the  “simplified”  method,  as  outlined  in  SEC  Staff Accounting  Bulletin  No.  107,  “Share-Based

Payment.”

● Risk-free interest rate – the Company estimates the risk-free interest rate using the U.S. Treasury yield curve for periods equal to the expected term of the options in

effect at the time of grant.

● Dividends – the Company uses an expected dividend yield of zero because the Company has not declared nor paid a cash dividend, nor are there any plans to declare a

dividend.

The Company estimated the fair value of stock options granted in the periods presented utilizing a Black-Scholes option-pricing model utilizing the following assumptions:

NOTE 11 – LICENSE/SUPPLIER AGREEMENTS

Sublicense and Inventory Purchase Agreements Relating to CLN1 Disease

In August 2020, the Company entered into sublicense and inventory purchase agreements with Taysha Gene Therapies (“Taysha”) relating to a potential gene therapy for CLN1
disease.  Under  the  sublicense  agreement,  Taysha  received  worldwide  exclusive  rights  to  intellectual  property  and  know-how  relating  to  the  research,  development,  and
manufacture  of  the  potential  gene  therapy,  which  the  Company  had  referred  to  as ABO-202.  Under  the  inventory  purchase  agreement,  the  Company  sold  to Taysha  certain
inventory  and  other  items  related  to  ABO-202.  The  Company  assessed  the  nature  of  the  promised  license  to  determine  whether  the  license  has  significant  stand-alone
functionality and evaluated whether such functionality can be retained without ongoing activities by the Company and determined that the license has significant stand-alone
functionality.  Furthermore,  the  Company  has  no  ongoing  activities  associated  with  the  license  to  support  or  maintain  the  license’s  utility.  Based  on  this,  the  Company
determined that the pattern of transfer of control of the license to Taysha was at a point in time.

The transaction price of the contract includes (i) $7.0 million of fixed consideration, (ii) up to $26.0 million of variable consideration in the form of event-based milestone
payments,  (iii)  up  to  $30.0  million  of  variable  consideration  in  the  form  of  sales-based  milestone  payments,  and  (iv)  other  royalty-based  payments  based  on  net  sales. The
event-based milestone payments are based on certain development and regulatory events occurring. At inception, the Company evaluated whether the milestone conditions had
been  achieved  and  if  it  was  probable  that  a  significant  cumulative  revenue  reversal  would  not  occur  before  recognizing  the  associated  revenue  and  determined  that  these
milestone payments were not within the Company’s control or the licensee’s control, such as regulatory approvals, and were not considered probable of being achieved until
those approvals were received. Accordingly, at inception, the Company fully constrained the $26.0 million of event-based milestone payments until such time that it is probable
that significant cumulative revenue reversal would not occur. The sales-based milestone payments and other royalty-based payments are based on a level of sales for which the
license is deemed to be the predominant item to which the royalties relate. The Company will recognize revenue for these payments at the later of (i) when the related sales
occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, the Company has not
recognized any sales-based or royalty revenue resulting from this licensing arrangement.

Under  this  arrangement,  the  Company  has  not  recognized  any  revenue  during  the  years  ended  December  31,  2023  and  2022,  respectively  based  on  event-based-milestone
payments. The Company has no contract assets as of December 31, 2023 and 2022. As of December 31, 2023 and 2022, the Company does not have any contract liabilities as a
result of this transaction.

Sublicense Agreement Relating to Rett Syndrome:

In October 2020, the Company entered into a sublicense agreement with Taysha for a gene therapy for Rett syndrome, including intellectual property related to MECP2 gene
constructs and regulation of their expression. The agreement grants Taysha worldwide exclusive rights to intellectual property developed by scientists at the University of North
Carolina  at  Chapel  Hill,  the  University  of  Edinburgh  and  the  Company,  and  the  Company’s  know-how  relating  to  the  research,  development,  and  manufacture  of  the  gene
therapy for Rett syndrome and MECP2 gene constructs and regulation of their expression.

The Company assessed the nature of the promised license to determine whether the license has significant stand-alone functionality and evaluated whether such functionality
can be retained without ongoing activities by the Company and determined that the license has significant stand-alone functionality. Furthermore, the Company has no ongoing
activities associated with the license to support or maintain the license’s utility. Based on this, the Company determined that the pattern of transfer of control of the license to
Taysha was at a point in time.

The transaction price of the contract includes (i) $3.0 million of fixed consideration, (ii) up to $26.5 million of variable consideration in the form of event-based milestone
payments,  (iii)  up  to  $30.0  million  of  variable  consideration  in  the  form  of  sales-based  milestone  payments,  and  (iv)  other  royalty-based  payments  based  on  net  sales. The
event-based  milestone  payments  are  based  on  certain  development  and  regulatory  events  occurring.  The  Company  evaluated  whether  the  milestone  conditions  have  been
achieved and if it is probable that a significant cumulative revenue reversal would not occur before recognizing the associated revenue. The Company determined that these
milestone payments are not within the Company’s control or the licensee’s control, such as regulatory approvals, and are not considered probable of being achieved until those
approvals are received. Accordingly, the Company has fully constrained the $26.5 million in event-based milestone payments until such time that it is probable that a significant
cumulative  revenue  reversal  would  not  occur. The  sales-based  milestone  payments  and  other  royalty-based  payments  are  based  on  a  level  of  sales  for  which  the  license  is
deemed to be the predominant item to which the royalties relate. The Company will recognize revenue for these payments at the later of (i) when the related sales occur, or (ii)
when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, the Company has not recognized any
sales-based or royalty revenue resulting from this licensing arrangement.

Under this arrangement, the Company recognized $3.5 million and $1.0 million in revenue during the years ended December 31, 2023 and 2022. The revenue recognized was
related to clinical milestones achieved by our sublicensor as per the sublicense agreement noted above. As of December 31, 2023 and 2022, the Company does not have any
contract assets or contract liabilities as a result of this transaction.

Ultragenyx License Agreement

On  May  16,  2022,  the  Company  and  Ultragenyx  Pharmaceutical  Inc.  (“Ultragenyx”)  entered  into  an  exclusive  license  agreement  (the  “License Agreement”)  for AAV  gene
therapy, ABO-102, for the treatment of Sanfilippo syndrome type A (MPS IIIA). Under the License Agreement, Ultragenyx assumed responsibility for the ABO-102 program
from the Company, with the exclusive right to develop, manufacture, and commercialize ABO-102 worldwide. Also pursuant to the License Agreement, following regulatory
approval, the Company is eligible to receive tiered royalties from mid-single-digit up to 10% on net sales and up to $30.0 million in commercial milestone payments. Both
forms of consideration comprise the transaction price to which the Company expects to be entitled in exchange for transferring the related intellectual property and certain,
contractually-specified, transition services to Ultragenyx. The sales-based royalty and milestone payments are subject to the royalty recognition constraint. As such, these fees
are not recognized as revenue until the later of: (a) the occurrence of the subsequent sale, and (b) the performance obligation to which they relate has been satisfied.

Additionally, pursuant to the License Agreement, Ultragenyx will reimburse the Company for certain development and transition costs actually incurred by the Company. These
costs  are  passed  through  to  Ultragenyx  without  mark-up.  The  Company  has  determined  that  these  costs  are  not  incurred  for  the  purpose  of  satisfying  any  performance
obligation under the License Agreement. Accordingly, the reimbursement of these costs is recognized as a reduction of research and development costs. As of December 31,
2023 and 2022, the Company does not have any contract assets or contract liabilities as a result of this transaction.

NOTE 12 – 401(k) PLAN

The Company has a tax-qualified employee savings and retirement plan (the “401(k) Plan”) covering all the Company’s employees in the United States. Pursuant to the 401(k)
Plan, employees may elect to reduce their current compensation by up to the statutorily prescribed annual limit ($22,500 in 2023 and $20,500 in 2022 for employees who are
under age 50 and $30,000 in 2023 and $27,000 in 2022 for employees who are age 50 and older) and to have the amount of such reduction contributed to the 401(k) Plan. The
401(k) Plan is intended to qualify under Section 401 of the Internal Revenue Code so that contributions by employees or by us to the 401(k) Plan, and income earned on 401(k)
Plan contributions, are not taxable to employees until withdrawn from the 401(k) Plan, and so that contributions by us, if any, will be deductible by us when made. At the
direction of each participant, the Company invests the assets of the 401(k) Plan in any of over 50 investment options. Company contributions under the 401(k) Plan were $0.3
million for the years ended December 31, 2023 and 2022.

On December 22, 2017, the “Tax Cuts and Jobs Act” was signed into law. The tax reform has the following effects on the Company: (1) permanently reduces the maximum
corporate income tax rate from 35% to 21% effective for tax years beginning after December 31, 2017, (2) allows temporary 100% expensing for certain business assets and
property placed in service after September 27, 2018 and before January 1, 2023, (3) disallows NOL carrybacks but allows for the indefinite carryforward of those NOLs which
applies to losses arising in tax years beginning after December 31, 2018 and, (4) limits NOL deductions for each year equal to the lesser of the available carryover or 80% of a
taxpayer’s  pre-NOL  deduction  taxable  income.  This  applies  to  losses  arising  in  tax  years  ending  on  or  after  December  31,  2017. As  of  December  31,  2023  and  2022,  the
Company has concluded that it is more likely than not that the Company will not realize the benefit of its deferred tax assets due to its history of losses. Accordingly, the net
deferred tax assets have been fully reserved.

In accordance with Section 382 of the Internal Revenue Code of 1986, as amended, a change in equity ownership of greater than 50% within a three-year period results in an
annual limitation on the Company’s ability to utilize its NOL carryforwards created during the tax periods prior to the change in ownership. The Company has not completed an
ownership  change  analysis  pursuant  to  Section  382.  Because  the  Company  has  incurred  cumulative  net  operating  losses  since  inception,  all  tax  years  remain  open  to
examination by U.S. federal and state income tax authorities.

As of December 31, 2023, the Company had $265.2 million of U.S. federal net operating loss carryforwards that do not expire and can be carried forward indefinitely. Such net
operating  loss  carryforwards  can  only  be  used  to  offset  80%  of  taxable  income  in  any  given  tax  year.  The  Company  also  has  $3.6  million  of  state  net  operating  loss
carryforwards in varying amounts depending on the different state tax laws.

The  Company  acquired  MacroChem  Corporation  on  March  25,  2009,  and  Somanta  Pharmaceuticals,  Inc.  on  January  4,  2008.  Both  of  these  corporations  were  loss-making
entities at the time of acquisition. As a result, the net operating losses related to those acquisitions may be subject to annual limitations. The Company has not performed a study
to determine whether or not there is such a limitation.

Valuation Allowance

At December 31, 2023 and 2022, the Company maintained a full valuation allowance on its deferred tax assets based on a history of cumulative losses. The Company will not
record income tax benefits in the financial statements until it is determined that it is more likely than not that the Company will generate sufficient taxable income to realize the
deferred  income  tax  assets.  In  2023,  the  valuation  allowance  increased  by  approximately  $8.7  million.  In  2022,  the  valuation  allowance  increased  by  approximately  $9.5
million.

Unrecognized Tax Benefits

At December 31, 2023 and 2022, the Company had no reserves for unrecognized tax benefits.

The Company and its subsidiaries are subject to taxation in the United States. The Company is subject to U.S. federal and state examinations for 2020 and forward, and 2019
and forward, respectively. However, net operating losses are subject to audit in any tax year in which those losses are utilized, notwithstanding the year of origin.

NOTE 14 – COMMITMENTS AND CONTINGENCIES

Litigation

The Company recognizes a liability for a contingency when it is probable that liability has been incurred and when the amount of loss can be reasonably estimated. When a
range of probable loss can be estimated, the Company accrues the most likely amount of such loss, and if such amount is not determinable, then the Company accrues the
minimum of the range of probable loss. As of December 31, 2023 and 2022, there was no litigation against the Company.

NOTE 15 – SUBSEQUENT EVENTS

Loan and Security Agreement

On  January  8,  2024  (the  “Closing  Date”),  the  Company  entered  into  a  Loan  and  Security Agreement  (the  “Agreement”)  with Avenue  Venture  Opportunities  Fund,  L.P.,  a
Delaware limited partnership, as administrative agent and collateral agent (“Avenue” and the “Agent”) and Avenue Venture Opportunities Fund II, L.P. , a Delaware limited
partnership (“Avenue 2” and, together with Avenue, the “Lenders”). Also on January 8, 2024, the Company entered into a Supplement to the Agreement (collectively with the
Agreement,  the  “Loan Agreement”)  with  the Agent  and  the  Lenders.  The  Loan Agreement  provides  for  senior  secured  term  loans  (the  “Loans”)  in  an  aggregate  principal
amount up to $50 million, with (i) a committed tranche of $20 million advanced on the Closing Date (“Tranche 1”), (ii) a committed tranche of up to $10 million which may be
advanced upon the request of the Company between June 30, 2024 and September 30, 2024, subject to the Company obtaining FDA approval of pz-cel in recessive dystrophic
epidermolysis bullosa, with the issuance of a Priority Review Voucher (“Tranche 2”), and (iii) a discretionary tranche of up to $20 million which may be advanced between
March 31, 2025 and March 31, 2026 (the “Discretionary Tranche”) provided at the discretion of the Lenders. The Loans are due and payable on July 1, 2027 (the “Maturity
Date”). The proceeds of the Loans are to be used for general corporate purposes.

F-29

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Loan principal is repayable in equal monthly installments beginning on April 8, 2025, with the possibility of deferring principal payments an additional nine to fifteen
months contingent upon (i) the Company obtaining FDA approval of pz-cel in recessive dystrophic epidermolysis bullosa, with the issuance of a Priority Review Voucher and
(ii) the Company raising $90 million of cumulative equity and/or non-dilutive capital subsequent to the Closing Date. The Loans bear interest at a rate per annum (subject to
increase during an event of default) equal to the greater of (i) the prime rate, as published by the Wall Street Journal from time to time, plus 5.00% and (ii) 13.50%.

The  Company  may,  subject  to  certain  parameters,  voluntarily  prepay  the  Loans,  in  whole,  at  any  time.  If  prepayment  occurs  on  or  before  the  one-year  anniversary  of  the
Closing  Date,  the  Company  is  required  to  pay  a  prepayment  fee  equal  to  3.00%  of  the  principal  amount  of  the  Loans  prepaid;  if  prepayment  occurs  after  the  one-year
anniversary of the Closing Date and on or before the two-year anniversary of the Closing Date, the Company is required to pay a fee equal to 2.00% of the principal amount of
the Loans; if prepayment occurs after the two-year anniversary of the Closing Date, the Company is required to pay a fee equal to 1.00% of the principal amount of the Loans.
A final payment fee of 5.00% of the principal amount of the funded Tranche 1, Tranche 2 Loans and Discretionary Tranche Loans is also due upon the Maturity Date or any
earlier date of prepayment.

The Company’s obligations under the Loan Agreement are secured by a pledge of substantially all of the Company’s assets. Pursuant to the Loan Agreement, the Company is
subject  to  a  financial  covenant  requiring  the  Company  to  maintain  at  all  times  $5  million  in  unrestricted  cash. The  Loan Agreement  also  contains  affirmative  and  negative
covenants customary for financings of this type that, among other things, limit the ability of the Company and its subsidiaries to (i) incur additional debt, guarantees or liens;
(ii) pay dividends; (iii) enter into certain change of control transactions; (iv) sell, transfer, lease, license, or otherwise dispose of certain assets; (v) make certain investments or
loans; and (vi) engage in certain transactions with related persons, in each case, subject to certain exceptions. The Loan Agreement also includes events of default customary for
financings of this type, in certain cases subject to customary periods to cure, following which the Agent may accelerate all amounts outstanding under the Loans.

Pursuant to the Supplement to the Loan and Security Agreement, Avenue also has the right to convert up to $3 million of the outstanding principal of the Loans into shares of
Company common stock (the “Conversion Right”) at a price per share equal to 120% of the exercise price of the Warrants (further discussed below) at any time while the
Loans are outstanding, subject to certain terms and conditions, including ownership limitations.

In  addition,  subject  to  applicable  law  and  specified  provisions  set  forth  in  the  Supplement  to  the  Loan  and  Security Agreement  and  solely  to  the  extent  permitted  under
applicable stock exchange rules without requiring stockholder approval, the Lenders may participate in certain equity financing transactions of the Company in an aggregate
amount of up to $1 million on the same terms, conditions and pricing offered by the Company to other investors participating in such financing transactions (such right, the
“Participation Right”). The Participation Right automatically terminates upon the earliest of (i) July 1, 2027, (ii) such time that the Lenders have purchased $1 million of the
Company’s equity securities in the aggregate pursuant to the Participation Right, and (iii) the repayment in full of all of the obligations under the Loan Agreement.

Warrants

On the Closing Date and pursuant to the funding of Tranche 1 of the Loan Agreement, the Company issued to each of Avenue and Avenue 2 (collectively, the “Warrantholders”)
warrants  to  purchase  up  to  $480,000  and  $1,920,000  worth  of  shares,  respectively,  of  Company  common  stock  (each,  a  “Warrant”  and  collectively,  the  “Warrants”).  The
Warrants expire on January 8, 2029 (the “Expiration Date”) and have an exercise price per share equal to the lesser of (i) $4.75 and (ii) the price per share of the Company’s
next bona fide round of equity financing before September 30, 2024 in which the Company sells or issues shares of its common stock, excluding certain excluded issuances as
defined in the Supplement. In addition, upon a change of control where the per share price of the Company common stock is less than or equal to two times that of the exercise
price, the Warrantholders would be entitled to receive the shares of common stock underlying the Warrant without payment of the exercise price.

The Warrantholders may exercise the Warrants at any time, or from time to time up to and including the Expiration Date, by making a cash payment equal to the exercise price
multiplied by the quantity of shares. The Warrantholders may also exercise the Warrants on a cashless basis by receiving a net number of shares calculated pursuant to the
formula set forth in the Warrants. The Warrants are subject to anti-dilution adjustments for stock dividends, stock splits, and reverse stock splits.

OUR MISSION

Abeona Therapeutics Inc.
Code of Business Conduct and Ethics

Our mission to harness the promise of genetic medicine to transform the lives of patients is inspired by our vision, to realize a world where cure is the new standard of care.

OUR VALUES

Working together to deliver cell and gene therapies for people impacted by serious diseases, and underpinned by our corporate values:

Patients First

Integrity

Innovation

Determination

Quality

Each of us knows and understands the responsibility we have. Our mission is supported by our commitment to respectful behavior, conducting business ethically and ensuring
compliance with the laws and regulations that govern our business and industry. Abeona’s leadership, including its Board of Directors, is committed to promoting an ethical and
compliant culture.

It is everyone’s responsibility to do the right thing by conducting business ethically, and we take it very seriously.

ABOUT THIS CODE

This Code of Conduct contains standards of conduct that apply to all Abeona employees and contractors, including our members of senior management, directors, vendors and
other business partners. Each of you has a personal responsibility to ensure that his or her actions abide by the letter and the spirit of this Code. All of our external stakeholders
– patients, providers, payors, governments – expect ethical behavior by all of our employees and contractors. This Code focuses on key areas of ethical responsibility, provides
guidance on appropriate behavior, and seeks to foster a culture of honesty and accountability throughout the Company. The values and principles set forth in this Code are
critically  important  to  the  Company  and  must  be  taken  seriously.  Violations  of  applicable  law  could  expose  Abeona  and  its  employees,  senior  managers,  directors,  and
contractors to fines, civil liability and/or criminal liability, and harm the Company’s reputation. For that reason, violations of applicable laws, this Code, or Company policies,
will lead to appropriate disciplinary action in accordance with the Company’s policies. Such disciplinary action may include reprimand, reimbursement of any loss or damage
suffered by the Company, or termination of employment or a contract. Under certain circumstances, the Company may be obligated to disclose violations of this Code to law
enforcement authorities or regulatory agencies.

COMPLIANCE WITH LAWS AND REGULATIONS

We  work  in  a  heavily  regulated  business  environment. Accordingly,  all Abeona  employees  and  contractors  must  obey  all  applicable  laws  and  regulations  that  govern  the
Company’s business operations. Additionally, all employees and contractors must abide by all Company policies and procedures that apply to the individual employee’s duties
and with the applicable laws of the country in which they operate. Abeona maintains a corporate compliance program led by our General Counsel and Head of Compliance. The
corporate compliance program is a system of controls designed to prevent or detect and correct violations of laws. Among the elements of our compliance program are policies,
standard operating procedures, training, and other control documents which all employees and contractors are expected to follow.

TRUTHFUL COMMUNICATIONS

Patients, healthcare providers, payors, investors, and regulators expect our employees and contractors to communicate in a truthful, non-misleading manner. This means that
statements about our company and its products must be accurate, balanced, substantiated by sound evidence, and in the best interests of patient care. Scientific exchange is also
an  important  element  of  our  business.  Preparing  and  sharing  timely,  accurate,  and  balanced  scientific  information  about  our  products  and  areas  of  therapeutic  interest  with
members  of  the  healthcare  community  is  vital  to  our  mission  to  serve  patients.  Similarly,  it  is  critical  that  we  share  high-quality,  timely  information  about  the  value  of  our
products with payors and other deliberative decision makers who make critical decisions about coverage, reimbursement, and purchasing of our products. Finally, Abeona is
committed  to  research  transparency  and  we  will  post  information  about  our  company’s  clinical  trials  on  public  registries  in  compliance  with  applicable  transparency  laws.
Employees and contractors are expected to use sound judgment and refer to Company policies and procedures when interacting with external parties on behalf of the Company,
whether through live interactions, social media, or other communications.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
GOOD OPERATING PRACTICES

Abeona  is  committed  to  researching,  developing,  manufacturing,  and  distributing  investigational  and  commercial  products  in  compliance  with  all  applicable  regulatory
standards and industry best practices. Our supply chain is subject to controls designed to ensure our products and product components are ethically and lawfully sourced, and
held,  packaged,  and  distributed  in  secure  conditions  intended  to  ensure  their  safety,  quality,  identify,  purity  and  potency.  We  are  committed  to  developing  and  maintaining
research,  development,  manufacturing,  testing,  distribution,  and  product  safety  systems  that  meet  Good  Clinical  Practices,  current  Good  Manufacturing  Practices,  Good
Laboratory Practices, and other relevant regulatory and industry standards. We must maintain a supplier controls program which includes diligence and oversight over our key
third-party partners, including contract research organizations, contract manufacturing organizations, suppliers, service providers and distributors. Together, these commitments
form  the  basis  of  Abeona’s  approach  to  overall  Good  Operating  Practices.  All  employees  and  contractors  involved  in  research,  development,  manufacturing,  and
distribution/supply chain functions are expected to follow applicable regulations and company standards governing these Good Operating Practices and report any incidents of
non-compliance to your supervisor or the General Counsel and Head of Compliance.

PRODUCT SAFETY AND INTEGRITY

Abeona  understands  its  responsibility  to  patients  regarding  the  safety  and  efficacy  of  our  products  and  each  employee  and  contractor  is  expected  to  take  this  responsibility
seriously. While no pharmaceutical product is ever entirely free from safety risks, we believe our commitment to Good Operating Practices and our commitment to comply with
the highest standards of pharmacovigilance and product safety reflect this patient responsibility. Abeona remains committed to timely notification of regulators, distribution
partners, providers, and patients of significant product quality issues in compliance with applicable regulations. All employees and customer-facing contractors are expected to
understand  and  follow  company  policies  governing  adverse  event  or  product  quality  incident  reporting  and  recordkeeping.  Employees  and  contractors  involved  in  product
development  or  supply  chain  are  expected  to  understand  and  follow  procedures  governing  product  quality  complaint  investigations,  recalls  or  corrections,  and  other  safety,
quality, and integrity matters.

MAINTAIN FAIR DEALING AND ETHICAL BUSINESS PRACTICES

Abeona and its employees and contractors must never provide an item of value to any party with the intent to improperly influence a decision to purchase, prescribe, refer, or
recommend Abeona products or services or for any other improper business advantage. We must follow company policies when interacting with healthcare providers, patients,
representatives  of  any  local  or  foreign  government  entity,  or  any  other  third-party.  We  must  also  abide  by  all  local  laws  governing  value  transfers,  gifts,  and  gratuities  to
healthcare providers and government officials. No person may take unfair advantage of any other employee, customer, patient, vendor, or competitor through manipulation,
concealment, abuse of privileged or confidential information, or disparagement of colleagues, customers, or competitors.

PROTECT CONFIDENTIAL INFORMATION AND RESPECTING PATIENT PRIVACY

Equally important is safeguarding the confidentiality of the personal information entrusted to us by healthcare providers and patients and abiding by legal and ethical standards
protecting that information. Acting in the best interest of patients as an organization means that we must protect and never misuse information entrusted to us. This obligation
continues after employment with the Company ends. Questions regarding the release or disclosure of confidential information or violations of the federal or state privacy laws
must be directed to the General Counsel and Head of Compliance.

 
 
 
 
 
 
 
 
 
 
 
AVOID CONFLICTS OF INTEREST

A “conflict of interest” exists when a person’s private interest interferes in any way, or appears to interfere, with the interests of the Company. A conflict situation may arise
when an employee or contractor takes actions or has personal, financial or other interests that may interfere with his or her ability to perform any of his or her work objectively
and effectively for the Company. Conflicts of interest may also arise when an employee or contractor, or a member of his or her family, receives improper personal benefits as a
result of his or her connection with the Company, such as inappropriately awarding a vendor contract to a family member. Similarly, employees and contractors are prohibited
from  competing  with Abeona  and  owe  a  duty  to  the  Company  to  advance  the  Company’s  interest  to  the  best  of  their  abilities.  Because  it  is  impossible  to  describe  every
potential conflict of interest, Abeona relies on the commitment of its employees and directors to exercise good judgment, to seek advice when appropriate, and to adhere to high
ethical standards in the conduct of their professional and personal affairs. Potential conflicts of interest include a situation in which an employee hires a vendor in which a
family member has a financial interest or a situation where an employee is on the board of a professional society that is soliciting financial support from Abeona. Potential
conflicts of interest should be discussed and resolved with the General Counsel and Head of Compliance.

FINANCIAL INTEGRITY

We have a responsibility to provide full, fair, accurate, timely, and clear disclosures in reports and documents we file with governmental and regulatory agencies. You must help
ensure that we meet that responsibility. Our CEO and CFO have additional responsibilities. Financial records are not only those that we report publicly. Records containing
financial information are found across the company and form the foundation of our public disclosures. Every financial record in every function must be accurate, true, and
complete. If you are involved in preparing reports and documents that Abeona submits to the U.S. Securities and Exchange Commission, be sure that the content is full, fair,
accurate, timely, and clear. Personnel must cooperate fully with Abeona’s independent public accountants and internal auditors and never take any action to coerce, manipulate
or mislead them.

BUSINESS RECORDS AND INFORMATION

Abeona has a responsibility to manage all records and information in a manner that protects the integrity of the information and ensures appropriate access. Our policy relating
to  records  and  information  facilitates  decision  making,  supports Abeona’s  legal,  financial,  regulatory,  and  contractual  obligations,  and  promotes  organizational  efficiency.
Confidential disclosure agreements protect a party’s disclosure of information by requiring the party that receives the information to use and handle it in a confidential manner.
Be familiar with the Records Retention Schedule as it applies to your function’s records. Retain all records for the time needed to comply with applicable laws and Abeona’s
policies. If a document hold order is issued by the General Counsel, do not destroy any records, information or data (regardless of its form, e.g., paper, electronic, microfiche)
that  you  are  required  to  retain  under  that  hold  order.  Never  create,  alter,  or  destroy  records  or  documents  for  the  purpose  of  impeding  the  efforts  of  any  governmental  or
regulatory agency.

SAFEGUARDING ABEONA’S INFORMATION

Information is an especially important asset for a company like Abeona. It gives us a key competitive advantage and must be protected. Information you create or receive on the
job is the company’s property, and you are responsible for safeguarding it. Abeona is well known in business and financial communities, and you may know someone who
would be interested in information you have about Abeona. However, employees must never discuss Abeona’s protected information with anyone outside the company unless
such  disclosure  has  been  approved  in  advance  as  required  by  our  policy. Abeona  employees  and  contractors  must  respect  and  maintain  the  confidentiality  of  information
entrusted  to  them  by  the  Company  or  its  customers.  Confidential  information  includes  all  non-public  information  that  might  be  of  use  to  competitors,  or  harmful  to  the
Company or its customers, if disclosed, such as patents, trade secrets, business planning documents, product pricing information, clinical data, and other sensitive information.
Before sending confidential information to any outside companies, institutions, or individuals, you need to obtain appropriate corporate authorization. A written confidential
disclosure agreement is also needed, except when the other party is a governmental regulatory authority, or a non-governmental body working on behalf of a governmental
authority. For example, a confidential disclosure agreement would not be required if the other party is a national health or drug regulatory agency, or a committee of scientists
officially tasked to work on the agency’s behalf. Contact the General Counsel and Head of Compliance with any questions, or to obtain a confidential disclosure agreement or
to ensure the appropriate confidentiality language is included in the applicable agreement with such company, institution or individual.

 
 
 
 
 
 
 
 
 
 
 
PROTECT COMPANY ASSETS

Theft,  carelessness,  and  waste  of  corporate  assets  and  resources,  including  paid  employment  time,  have  a  direct  impact  on  the  Company’s  profitability.  Employees  and
contractors  are  responsible  for  ensuring  that  the  Company’s  assets  are  utilized  efficiently  and  appropriately  for  legitimate  business  purposes  only.  Employees  who  engage
contractors or vendors are responsible for ensuring that these parties abide by the principles in this Code, including to ensure that the Company only pays for necessary, lawful
services that are actually performed by these parties for the Company in a quality and timely manner, in compliance with company policies governing service arrangements,
travel expenses, and financial recordkeeping.

ENSURE ACCURATE RECORDKEEPING

Abeona  requires  honest  and  accurate  recording  and  reporting  of  financial  information  and  data  to  make  responsible  business  decisions. All  employees  must  ensure  that  all
documentation, including, but not limited to records, production standards, quality control, expense reports, formal certifications, and financial statements, accurately reflect the
true nature of a fact or event and are completed and maintained in compliance with company document control standards. Specific regulations apply to accounting, research,
manufacturing, and pharmacovigilance records, and employees or contractors working in those functional areas are expected to understand and abide by those regulations. All
employees and contractors are responsible to report to their manager or the General Counsel and Head of Compliance any questionable accounting, recordkeeping, or data that
may come to their attention. Records should be retained, disposed, or destroyed according to the Company’s record retention policies and legal and regulatory requirements. All
employees and contractors must maintain records in the appropriate format and have them readily accessible for the timeframes required by federal and state regulations.

INSIDER TRADING

Many countries have laws regarding insider trading. In the U.S., for example, you may not buy or sell any type of security while aware of material, non-public information
relating to the company issuing the security, whether that company is Abeona or another company. You also may not share material, non-public information with others. Even if
the activities prohibited under Abeona’s Insider Trading Policy are not illegal in the country where you are based, our Insider Trading Policy applies to you regardless of your
location.  Abeona’s  policy  requirements  also  apply  to  family  (including  spouses,  minor  children,  or  any  family  member  living  in  the  same  household)  of  Abeona  staff.
Employees are responsible for reviewing and acknowledging the Abeona’s Insider Trading Policy.

INVESTOR AND MEDIA RELATIONS

As a publicly traded company, Abeona has a responsibility to maintain an orderly flow of information to the general public and to its investors. All of Abeona’s dealings with
the investment community and the media, including reporters, must be properly managed to make certain that accurate and timely information is given to investors and the
public. We  also  need  to  be  careful  to  comply  fully  with  all  laws  governing  our  disclosures.  Reporters,  media  representatives,  investors,  and  investment  analysts  may  try  to
solicit information directly from you. Only members of senior management or designated spokespersons are authorized to speak to the news media. Investor inquiries will be
handled in a similar manner by Investor Relations. Employees or contractors who receive an inquiry about Abeona from an investor, financial analyst, the media or any other
outside party, should not respond to the request unless specifically authorized and trained to do so by the Company.

 
 
 
 
 
 
 
 
 
 
 
SEEK GUIDANCE AND REPORT VIOLATIONS

Abeona actively promotes lawful, honest, and ethical behavior in all its business activities and by all of its employees and contractors. The Company expects supervisors to
model this behavior for their employees. Employees are encouraged to speak to their supervisors or the General Counsel and Head of Compliance, at any time, if there is any
doubt about the best course of action in a particular situation. If an Abeona employee or contractor has reason to believe that there has been a violation of this Code, company
policies, or the law, such information should immediately be reported to the General Counsel and Head of Compliance directly, or through the mechanisms provided below.
This duty to report includes any suspected violation of any Federal healthcare program requirements (such as suspected fraud, waste, or abuse under the Medicare program), as
well as FDA and other regulatory requirements. Employees or contractors (including external vendors) who wish to report a suspected compliance issue anonymously may do
so by leaving a message via the Abeona Compliance Helpline: 844-855-9977.

NON-RETALIATION STATEMENT

Abeona takes a zero-tolerance approach to retaliation. Under Abeona policy, no employee or contractor will suffer any adverse consequence or retaliation as a result of good
faith  reporting  of  suspected  fraud  or  other  misconduct  or  a  possible  violation  of  law.  If  you  believe  you  have  been  retaliated  against,  you  should  immediately  contact  the
General Counsel and Head of Compliance. All reported or suspected retaliation will be investigated thoroughly and expeditiously.

COOPERATION WITH REGULATORS AND LAW ENFORCEMENT

Abeona is committed to acting in a transparent, cooperative manner with regulators and law enforcement authorities. For example, it is our policy to receive and interact with
regulatory agency inspectors in a professional, courteous, and transparent manner. It is also our policy to cooperate with government inquiries and investigations. Employees
and contractors must never intentionally mislead or knowingly withhold information from a regulator or member of law enforcement. Employees and contractors should refrain
from engaging with regulators or enforcement authorities on behalf of Abeona without approval from the General Counsel. The company maintains protocols for dealing with
regulatory inspections or requests for information from regulators and enforcement authorities. If you are contacted by a regulator or member of law enforcement regarding
Abeona, please immediately contact the General Counsel’s office for guidance.

 
 
 
 
 
 
 
 
 
 
EXHIBIT 19

I.

Purpose

ABEONA THERAPEUTICS INC.
POLICY ON INSIDER TRADING AND CONFIDENTIALITY

The  purpose  of  this  Policy  on  Insider  Trading  and  Confidentiality  (the  “Policy”)  is  to  provide  guidelines  with  respect  to  securities  of  Abeona  Therapeutics  Inc.
(“Abeona” or “Company”) and the handling of confidential and material nonpublic information about the Company and the companies with which the Company does business.
The  Company’s  Board  of  Directors  has  adopted  this  Policy  to  promote  compliance  with  federal  securities  laws  that  prohibit  certain  persons  who  are  aware  of  material
nonpublic information about a company from: (i) trading in securities of that company, or (ii) providing material nonpublic information to other persons who may trade based
on that information.

II.

Persons Subject to the Policy

This Policy applies to all officers of the Company and its subsidiaries, all members of the Company’s Board of Directors, and all employees of the Company and its
subsidiaries. The Company may also determine that other persons should be subject to this Policy, such as contractors or consultants who have access to material nonpublic
information. This Policy also applies to family members, other members of a person’s household and entities controlled by a person covered by this Policy, as described below.

III.

Transactions Subject to the Policy

This Policy applies to transactions in the Company’s securities (collectively referred to in this Policy as “Company Securities”), including the Company’s common
stock, options to purchase common stock, or any other type of securities that the Company may issue, including (but not limited to) preferred stock, convertible debentures and
warrants, as well as derivative securities, such as restricted stock awards, and derivative securities that are not issued by the Company, such as exchange-traded put or call
options or swaps relating to the Company’s Securities.

IV.

Administration of the Policy

The Company’s Chief Financial Officer shall serve as the Compliance Officer for the purposes of this Policy, and in his absence, the Company’s General Counsel or
another employee designated by the Compliance Officer shall be responsible for administration of this Policy. All determinations and interpretations by the Compliance Officer
shall be final and not subject to further review.

V.

General Trading Policy

Generally,  it  is  against  the  law  to  buy  or  sell  any  securities  while  in  possession  of  material  nonpublic  information  (“MNPI”)  relevant  to  that  security,  or  to
communicate such information to others who trade based on such information (known as “tipping”). In recent years, Congress has toughened the penalties for trading on or
tipping MNPI and the U.S. Securities and Exchange Commission (“SEC”) has aggressively brought actions against such traders and tippers.

ANY  PERSON WHO  ENGAGES  IN  INSIDER TRADING  OR TIPPING  CAN  FACE A  SUBSTANTIAL  JAIL TERM  (UP TO  10 YEARS) AND  FINES  UP TO THREE
TIMES THE PROFIT GAINED (OR LOSS AVOIDED) BY THAT PERSON AND/OR HIS OR HER “TIPPEES”, AS WELL AS SUBSTANTIAL CIVIL LIABILITIES.

Abeona may also be liable for the insider trading violations of an employee, if it is found that the Company failed to take appropriate steps to prevent insider trading

by an employee or director.

Abeona’s employees, officers, and directors must not engage in transactions in Company Securities if they possess MNPI as to Abeona and must not communicate

such information to any third party except persons who have a legitimate need to know such information and understand their obligation not to trade on it.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Whether  a  particular  item  was  “material”  will  be  judged  with  20-20  hindsight.  Accordingly,  when  in  doubt  as  to  a  particular  item  of  information,  you  should

presume it to be material and not to have been disclosed to the public.

More generally, all our employees, officers, and directors are reminded to use extreme care to assure that confidential information is not inadvertently disclosed to
others. Be particularly careful to avoid discussing in public places, such as lobbies, trains, airports, or restaurants, any matter that might be sensitive or confidential. Meetings in
which confidential information is discussed should be conducted behind closed doors. Even inadvertent “leaks” of confidential information can create problems for Abeona and
our employees, officers, and directors.

AS WITH OUR OTHER EMPLOYEE POLICIES, VIOLATION OF THIS POLICY BY ANY EMPLOYEE OF ABEONA OR ANY OF OUR SUBSIDIARIES (OR BY ANY
FAMILY MEMBER OF THE EMPLOYEE) IS GROUNDS FOR IMMEDIATE DISCIPLINARY ACTION, INCLUDING POSSIBLE DISMISSAL FROM EMPLOYMENT.

VI.

Definition of Material Nonpublic Information

In general, information is “material” as to a security if a reasonable investor would consider the information significant in deciding whether to buy, hold, or sell the
security. Examples of events or developments that should be presumed to be “material” in the context of Company Securities would be events such as the following, when they
have not yet been fully disclosed to the public:

● the execution of a licensing or collaboration agreement;
● clinical results for an Abeona product candidate (whether favorable or adverse);
● any significant regulatory action, including the receipt or non-receipt of a regulatory approval;
● knowledge of a trend in Abeona’s results of operations not yet fully disclosed to the public;
● gain or loss not yet disclosed to the public;
● termination of a significant agreement;
● a significant acquisition;
● major litigation;
● significant related party transactions;
● a purchase or sale of substantial assets or other significant corporate transaction;
● a change in management; or
● impending bankruptcy or the existence of severe liquidity problems.

These examples are illustrative only and are not intended to be exhaustive examples of material information.

Information that has not been disclosed to the public is generally considered to be nonpublic information. To establish that the information has been disclosed to the
public, it may be necessary to demonstrate that the information has been widely disseminated. Information generally would be considered widely disseminated if it has been
disclosed through newswire services, publication in a widely available newspaper, magazine or news website, the Dow Jones “broad tape,” or public disclosure documents filed
with the SEC that are available on the SEC’s website. By contrast, information would likely not be considered widely disseminated if it is available only to the Company’s
employees, or if it is only available, for example, to a select group of analysts, brokers, and/or institutional investors.

Once information is widely disseminated, it is still necessary to provide the investing public with sufficient time to absorb the information. Generally, information
should not be considered fully absorbed by the marketplace until after the first business day after the day on which the information is released. If, for example, the Company
were to make an announcement on a Monday, you should not trade in Company Securities until the market opens on Wednesday. Depending on the particular circumstances,
the Company may determine that a longer or shorter period should apply to the release of specific material nonpublic information.

 
 
 
 
 
 
 
 
 
 
 
 
VII.

Policy Procedures

The  Company  has  established  additional  procedures  to  assist  the  Company  in  the  administration  of  this  Policy,  facilitate  compliance  with  laws  prohibiting  insider
trading  while  in  possession  of  material  nonpublic  information,  and  avoid  the  appearance  of  any  impropriety.  These  additional  procedures  are  applicable  only  to  those
individuals described below.

A.

Pre-Clearance Procedures

The persons designated by the Compliance Officer as being subject to these procedures, as well as the Family Members and Controlled Entities of such persons, may
not engage in any transaction in Company Securities without first obtaining pre-clearance of the transaction from the Compliance Officer. A request for pre-clearance should be
submitted to the Compliance Officer at least two business days in advance of the proposed transaction. The Compliance Officer is under no obligation to approve a transaction
submitted for pre-clearance and may determine not to permit the transaction. If a person seeks pre-clearance and permission to engage in the transaction is denied, then he or
she should refrain from initiating any transaction in Company Securities and should not inform any other person of the restriction.

When a request for pre-clearance is made, the requestor should carefully consider whether he or she may be aware of any material nonpublic information about the
Company  and  should  describe  fully  those  circumstances  to  the  Compliance  Officer.  The  requestor  should  also  indicate  whether  he  or  she  has  effected  any  non-exempt
“opposite-way” transactions within the past six months and should be prepared to report the proposed transaction on an appropriate Form 4 or Form 5. The requestor should
also be prepared to comply with SEC Rule 144 and file a Form 144, if necessary, at the time of any sale.

In  this  regard,  directors  and  certain  officers  of  the  Company  are  subject  to  certain  reporting  requirements,  trading  restrictions  and  “short  swing”  profit  recovery
provisions under Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In particular, each director and executive officer of Abeona must, as a
general rule pursuant to Section 16, report transactions in Company Securities on a Form 4 filed with the SEC no later than 10:00 p.m. Eastern Time on the second business day
following the day on which the transaction occurs (the trade date, not the settlement date). This general requirement that a Form 4 be filed within two business days of the trade
date  is  modified  in  the  case  of  purchases  and  sales  of  Company  Securities  made  pursuant  to  a  contract,  instruction,  or  written  plan  that  satisfies  the  affirmative  defense
conditions of Rule 10b5-1(c) of the Exchange Act (i.e., a Rule 10b5-1 trading plan) or discretionary transactions made pursuant to an employee benefit plan, provided that the
director or executive officer of Abeona does not select or has not selected the date of execution of the transaction. In these particular cases, a director or executive officer of
Abeona  must  file  a  Form  4  reporting  the  applicable  transaction  before  the  end  of  the  second  business  day  following  the  day  on  which  the  executing  broker,  dealer  or  plan
administrator, as applicable, notifies the director or executive officer of the execution of the transaction (rather than two business days after the trade date), provided that the
notification date is not later than the third business day following the trade date. If the notification is provided after the third business day following the trade date, the two-day
period runs from that third business day and the transaction must be reported on a Form 4 no later than the fifth business day following the trade date.

B.

Quarterly Trading Restrictions

The  persons  designated  by  the  Compliance  Officer  as  subject  to  this  restriction,  as  well  as  their  Family  Members  or  Controlled  Entities,  may  not  conduct  any
transactions involving the Company’s Securities (other than as specified by this Policy), during a “Blackout Period” beginning 14 calendar days prior to the date of the public
release of the Company’s earnings results for each fiscal quarter and ending at the market open of the second business day following such release.

C.

Event-Specific Trading Restriction Periods

From time to time, an event may occur that is material to the Company and is known by only a few directors, officers, or employees. So long as the event remains

material and nonpublic, the persons designated by the Compliance Officer may not trade Company Securities.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  addition,  the  Company’s  financial  results  may  be  sufficiently  material  in  a  particular  fiscal  quarter  that,  in  the  judgment  of  the  Compliance  Officer,  designated
persons should refrain from trading in Company Securities even sooner than the typical Blackout Period described above. In that situation, the Compliance Officer may notify
these persons that they should not trade in the Company’s Securities, without disclosing the reason for the restriction.

The existence of an event-specific trading restriction period or extension of a Blackout Period may not necessarily be announced to the Company as a whole, and when
not announced to the Company as a whole should not be communicated to any other person. Even if the Compliance Officer has not designated you as a person who should not
trade due to an event-specific restriction, you should not trade while aware of material nonpublic information. Exceptions will not be granted during an event-specific trading
restriction period.

VIII.

Transactions by Family Members and Others

This Policy applies to your family members who reside with you (including a spouse, a child, a child away at college, stepchildren, grandchildren, parents, stepparents,
grandparents, siblings and in-laws), anyone else who lives in your household, and any family members who do not live in your household but whose transactions in Company
securities are directed by you or are subject to your influence or control, such as parents or children who consult with you before they trade in Company Securities (collectively
referred to as “Family Members”). You are responsible for the transactions of these other persons and therefore should make them aware of the need to confer with you before
they trade in Company Securities, and you should treat all such transactions for the purposes of this Policy and applicable securities laws as if the transactions were for your
own account. This Policy does not, however, apply to personal securities transactions of Family Members where the purchase or sale decision is made by a third party not
controlled by, influenced by, or related to you or your Family Members.

IX.

Trading by Officer, Director, or Employee Fiduciary Accounts

This Policy applies to any entities that you influence or control, including any trusts, partnerships, or corporations (collectively referred to as “Controlled Entities”),

and transactions by these Controlled Entities should be treated for the purposes of this Policy and applicable securities laws as if they were for your own account.

X.

Transactions Under Company Plans

A.

Restricted Stock Awards

This Policy does not apply to the vesting of restricted stock, or the exercise of a tax withholding right pursuant to which you elect to have the Company withhold

shares of stock to satisfy tax withholding requirements upon the vesting of any restricted stock. The Policy does apply, however, to any market sale of restricted stock.

B.

Stock Options

The foregoing trading period restrictions do not apply to exercises of stock options under our stock option and equity incentive plans. Exercises of stock options by
directors and certain officers of Abeona, however, do require prior notice as described above. Sales of option shares require prior notice and remain subject to other applicable
restrictions.

C.

Other Similar Transactions

Any other purchase of Company Securities from the Company or sales of Company Securities to the Company are not subject to this Policy.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
XI.

Special and Prohibited Transactions

A.

“Short Sales”

“Short sales” of Company Securities by any employee, officer, or director (i.e., the sale of a security that the seller does not own) are absolutely prohibited. Short sales
may  evidence  an  expectation  on  the  part  of  the  seller  that  the  securities  will  decline  in  value,  and  therefore  have  the  potential  to  signal  to  the  market  that  the  seller  lacks
confidence in the Company’s prospects In addition, Section 16(c) of the Exchange Act prohibits officers and directors from engaging in short sales.

B.

Hedging Transactions

Hedging  or  monetization  transactions  can  be  accomplished  through  a  number  of  possible  mechanisms,  including  through  the  use  of  financial  instruments  such  as
prepaid variable forwards, equity swaps, collars, and exchange funds. Such transactions may permit a director, officer, or employee to continue to own Company Securities
obtained through employee benefit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, the director, officer or employee may no longer
have the same objectives as the Company’s other shareholders. Therefore, directors, officers and employees are prohibited from engaging in any such transactions.

XII.

Rule 10b5-1 Plans

Rule 10b5-1 under the Exchange Act provides a defense from insider trading liability. To be eligible to rely on this defense, a person subject to this Policy must enter
into a Rule 10b5-1 plan for transactions in Company Securities that meets certain conditions specified in the Rule (a “Rule 10b5-1 Plan”). If the plan meets the requirements of
Rule  10b5-1,  Company  Securities  may  be  purchased  or  sold  without  regard  to  certain  insider  trading  restrictions.  To  comply  with  the  Policy,  a  Rule  10b5-1  Plan  must  be
approved by the Compliance Officer and meet the requirements of Rule 10b5-1 and the Company’s Guidelines for Rule 10b5-1 Plans, if any, which may be obtained from the
Compliance Officer. In general, a Rule 10b5-1 Plan must be entered into at a time when the person entering into the plan is not aware of material nonpublic information. Once
the plan is adopted, the person must not exercise any influence over the amount of securities to be traded, the price at which they are to be traded or the date of the trade. The
plan must either specify the amount, pricing, and timing of transactions in advance or delegate discretion on these matters to an independent third party.

Any Rule 10b5-1 Plan must be submitted for approval to the Compliance Officer five days prior to the entry into the Rule 10b5-1 Plan. No further pre-approval of
transactions  conducted  pursuant  to  the  Rule  10b5-1  Plan  will  be  required.  Please  note  that  under  Rule  10b5-1,  there  is  generally  a  90-day  “cooling  off”  period  after  the
adoption of a 10b5-1 trading plan, before the expiration of which no purchases or sales may occur.

XIII.

Confidentiality

Serious  problems  could  be  caused  for Abeona  by  unauthorized  disclosure  of  internal  information  about  us,  whether  or  not  for  the  purpose  of  facilitating  improper
trading in the stock. Abeona personnel should not discuss internal company matters or developments with anyone outside of Abeona, except as required in the performance of
regular corporate duties.

This prohibition applies specifically (but not exclusively) to inquiries about us which may be made by the financial press, investment analysts or others in the financial
community. It is important that all such communications on behalf of Abeona be through an appropriately designated officer under carefully controlled circumstances. Unless
you are expressly authorized to the contrary, if you receive any inquiries of this nature, you should decline comment and refer the inquirer to the Compliance Officer.

XIV.

Post-Termination Transactions

This Policy continues to apply to transactions in Company Securities even after termination of service to the Company. If an individual is in possession of material
nonpublic  information  when  his  or  her  service  terminates,  that  individual  may  not  trade  in  Company  Securities  until  that  information  has  become  public  or  is  no  longer
material.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
XV.

Disclaimer of New Liabilities

This Policy is not intended and shall not be deemed to impose on Abeona or its employees, officers, or directors any civil, criminal or other liability that would not

exist in the absence of this policy statement.

XVI.

Certification

All persons subject to this Policy must certify their understanding of, and intent to comply with, this Policy.

1.

I have read and understand the Abeona Therapeutics Inc. Policy on Insider Trading and Confidentiality (the “Policy”). I understand that the Compliance Officer is

“Incentive-Based Compensation” means any compensation that is granted, earned, or vested, based wholly or in part upon the attainment of a Financial Reporting
Measure.2  Incentive-Based  Compensation  does  not  include,  among  other  forms  of  compensation,  equity  awards  that  vest  exclusively  upon  completion  of  a
specified  employment  period,  without  any  performance  condition,  and  bonus  awards  that  are  discretionary  or  based  on  subjective  goals  or  goals  unrelated  to
Financial Reporting Measures.
“Received” — Incentive-Based Compensation is deemed “Received” for the purposes of this Policy in the Company’s fiscal period during which the Financial
Reporting Measure applicable to the Incentive-Based Compensation award is attained, even if the payment or grant of the Incentive-Based Compensation occurs
after the end of that period.
“Recovery Period” means the three completed fiscal years immediately preceding the date on which the Company is required to prepare a Restatement, which
date is the earlier of (i) the date the Board, a committee of the Board, or the officer or officers of the Company authorized to take such action if Board action is not
required, concludes, or reasonably should have concluded, that the Company is required to prepare a Restatement or (ii) a date that a court, regulator or other
legally authorized body directs the Company to prepare a Restatement.
“Restatement”  means  that  the  Company  is  required  to  prepare  an  accounting  restatement  due  to  material  noncompliance  of  the  Company  with  any  financial
reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements (i) that
is material to the previously issued financial statements, or (ii) that would result in a material misstatement if the error were corrected in the current period or left
uncorrected in the current period. Determination of whether noncompliance is material for the purpose of the preceding sentence will be determined consistent
with the Applicable Rules.3

Section B-2. Recovery on a Restatement.

In the event that the Company is required to prepare a Restatement, the Company shall reasonably promptly recover from an Executive Officer the amount of any erroneously
awarded  Incentive-Based  Compensation  that  is  Received  by  such  Executive  Officer  during  the  Recovery  Period.  The  amount  of  erroneously  Received  Incentive-Based
Compensation  will  be  the  excess  of  the  Incentive-Based  Compensation  Received  by  the  Executive  Officer  (whether  in  cash  or  shares)  based  on  the  erroneous  data  in  the
original financial statements over the Incentive-Based Compensation (whether in cash or in shares) that would have been Received by the Executive Officer had such Incentive-
Based Compensation been based on the restated results, without respect to any tax liabilities incurred or paid by the Executive Officer.

Recovery of any erroneously awarded compensation under this Policy is not dependent on fraud or misconduct by any Executive Officer in connection with a Restatement.

Without limiting the foregoing, for Incentive-Based Compensation based on the Company’s stock price or total shareholder return, where the amount of erroneously awarded
compensation  is  not  subject  to  mathematical  recalculation  directly  from  the  information  in  the  Restatement,  (a)  the  amount  shall  be  based  on  the  Company’s  reasonable
estimate of the effect of the Restatement on the stock price or total shareholder return upon which the Incentive-Based Compensation was Received and (b) the Company shall
maintain documentation of the determination of that reasonable estimate and provide such estimate to the Regulators as required by the Applicable Rules.

2  “Incentive-Based  Compensation”,  includes,  but  is  not  limited  to,  (i)  non-equity  incentive  plan  awards  that  are  earned  based  wholly  or  in  part  on  satisfying  a  Financial
Reporting  Measure  performance  goal;  (ii)  bonuses  paid  from  a  “bonus  pool,”  the  size  of  which  is  determined  based  wholly  or  in  part  on  satisfying  a  Financial  Reporting
Measure  performance  goal;  (iii)  other  cash  awards  based  on  satisfaction  of  a  Financial  Reporting  Measure  performance  goal;  (iv)  restricted  stock,  restricted  stock  units,
performance  share  units,  stock  options,  and  stock  appreciation  rights  that  are  granted  or  become  vested  wholly  or  in  part  on  satisfying  a  Financial  Reporting  Measure
performance goal; and (v) proceeds received upon the sale of shares acquired through an incentive plan that were granted or vested based wholly or in part on satisfying a
Financial Reporting Measure performance goal.
3 The issuing release for the Applicable Rules suggests that determinations of materiality should be made on a facts and circumstances basis, consistent with accounting rules
and  consistent  prior  SEC  guidance  on  level  of  materiality.  Specifically,  they  point  to:  Staff  Accounting  Bulletin  No.  99,  Materiality  (Aug.  12,  1999)  and  Staff  Accounting
Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (Sept. 13, 2006).

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Section B-3. Covered Executive Officers and Covered Incentive-Based Compensation.

This  Policy  covers  all  persons  who  are  Executive  Officers  at  any  time  during  the  Recovery  Period  for  which  Incentive-Based  Compensation  is  Received  or  during  the
performance period applicable to such Incentive-Based Compensation. Incentive-Based Compensation shall not be recovered under this Policy to the extent Received by any
person  before  the  date  the  person  served  as  an  Executive  Officer.  Subsequent  changes  in  an  Executive  Officer’s  employment  status,  including  retirement  or  termination  of
employment, do not affect the Company’s right to recover Incentive-Based Compensation pursuant to this Policy.

This Policy shall apply to Incentive-Based Compensation that is Received by any Executive Officer on or after the Effective Date and that results from attainment of a Financial
Reporting Measure based on or derived from financial information for any fiscal period ending on or after the Effective Date. For the avoidance of doubt, this will include
Incentive-Based  Compensation  that  may  have  been  approved,  awarded,  or  granted  to  an  Executive  Officer  on  or  before  the  Effective  Date  if  such  Incentive-Based
Compensation is Received after the Effective Date.

Section B-4. Methods of Recovery; Limited Exceptions.

The Board shall determine, in its sole discretion, the method of recovering any Incentive-Based Compensation Received pursuant to this Policy, consistent with applicable law,
which may include, without limitation, the methods of recovery described in Article C.

No recovery shall be required if any of the following conditions are met and the Committee (or an independent committee of the Board consistent with the Applicable Rules)
determines that, on such basis, recovery would be impracticable:

(a)

(b)

(c)

the direct expense paid to a third party to assist in enforcing this Article B would exceed the amount to be recovered; provided that prior to making a determination
that it would be impracticable to recover any Incentive-Based Compensation based on the expense of enforcement, the Company shall (i) have made a reasonable
attempt to recover the Incentive-Based Compensation, (ii) have documented such reasonable attempts to recover, and (iii) provide the documentation to Nasdaq;

recovery would violate home country law where that law was adopted prior to November 28, 2022; provided that, prior to making a determination that it would be
impracticable to recover any Incentive-Based Compensation based on a violation of home country law, the Company shall (i) have obtained an opinion of home
country counsel, acceptable to Nasdaq, that recovery would result in such violation, and (ii) provide a copy of such opinion to Nasdaq; or

recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees, to fail to meet the requirements
of Section 401(a)(13) or Section 411(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and U.S. Treasury regulations promulgated thereunder.

Section B-5. Reporting; Disclosure; Monitoring.

The Company shall make all required disclosures and filings with the Regulators with respect to this Policy in accordance with the requirements of the Applicable Rules, and
any other requirements applicable to the Company, including the disclosures required in connection with SEC filings.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ARTICLE C
METHODS OF RECOVERY

Section C-1. Subject to Section B-4, in the event that the Board determines that this Policy should apply, to the extent permitted by applicable law, the Company shall, as
determined by the Board in its sole discretion, take any such actions as it deems necessary or appropriate to recover Clawback Compensation. The actions may include, without
limitation (and as applicable):

(a)
(b)
(c)
(d)

(e)
(f)
(g)

forfeit, reduce, or cancel any Clawback Compensation (whether vested or unvested)that has not been distributed or otherwise settled;
seek recovery of any Clawback Compensation that was previously paid to the Executive Officer;
seek recovery of any amounts realized on the vesting, exercise, settlement, sale, transfer, or other disposition of any equity-based Clawback Compensation;
recoup any amount in respect of Clawback Compensation that was contributed or deferred to a plan that takes into account Clawback Compensation (excluding
certain tax-qualified plans, but including deferred compensation plans, and supplemental executive retirement plans, and insurance plans to the extent otherwise
permitted by applicable law, including Section 409A of the Code) and any earnings accrued on such Clawback Compensation;
except as otherwise required by this Policy, determine whether Clawback Compensation should be recouped on a pre-tax or after-tax basis;
offset, withhold, eliminate or cause to be forfeited any compensation that could be paid or awarded to the Executive Officer after the date of determination; and
take any other remedial and recovery action permitted by law, as determined by the Board.

In addition, (x) if a breach of fiduciary duty or other violation of law has occurred, the Board may authorize legal action for such breach of fiduciary duty or other violation of
law and take such other actions to enforce the obligations of the Executive Officer to the Company as the Board deems appropriate or (y) in the event that an Executive Officer
fails to repay or reimburse erroneously awarded compensation that is subject to recovery, the Board may seek to compel such individual to reimburse the Company for any and
all expenses reasonably incurred (including legal fees) by the Company in recovering erroneously awarded compensation under this Policy.

Section  C-2.  Notice.  Before  the  Company  takes  action  to  seek  recovery  of  compensation  pursuant  to  this  Policy  against  an  Executive  Officer,  the  Company  may,  in  its
discretion, take steps to provide such individual with advance written notice of such clawback; provided that such provision of notice shall not in any way delay the reasonably
prompt recovery of any erroneously awarded Incentive-Based Compensation pursuant to this Policy.

Section C-3. No Indemnification. The Company shall not indemnify any current or former Executive Officer against the loss of erroneously awarded compensation, and shall
not pay or reimburse any such person for premiums incurred or paid for any insurance policy to fund such person’s potential recovery obligations.
