Item 1. Business.

General

RegeneRx  Biopharmaceuticals,  Inc.  (“RegeneRx”  or  the  “Company”)  (OTCQB:RGRX)  is  a  biopharmaceutical  company  focused  on  the
development of a novel therapeutic peptide, Thymosin beta 4, or Tß4, for tissue and organ protection, repair, and regeneration. We have formulated Tß4
into three distinct product candidates in clinical development:

•        RGN-259, a preservative-free topical eye drop for regeneration of corneal tissues damaged by injury, disease or other pathology;

•        RGN-352,  an  injectable  formulation  to  treat  cardiovascular  diseases,  central  and  peripheral  nervous  system  diseases,  and  other  medical

indications that may be treated by systemic administration; and

•        RGN-137, a topical gel for dermal wounds and reduction of scar tissue.

We are continuing strategic partnership discussions with biotechnology and pharmaceutical companies and the U.S. military regarding the further

clinical development of all of our product candidates.

Current Financial Status

In October 2020, we sold a series of convertible promissory notes to management, the Company’s Board of Directors and accredited investors
including Essetifin S.p.A., our largest stockholder (the “2020 Notes”). The sale of the 2020 Notes resulted in gross proceeds to the Company of $500,000.
The 2020 Notes contain a $0.36 conversion price and the purchasers also received a warrant exercisable at $0.45 to purchase additional shares of common
stock equal to 75% of the number of shares into which each of the 2020 Notes is initially convertible (the “2020 Warrants”). On March 2, 2018, we entered
into  the  Reprice  Agreement  with  Sabby  Healthcare  Master  Fund,  Ltd.,  and  Sabby  Volatility  Warrant  Master  Fund,  Ltd.  (collectively,  “Sabby”).  In
January 2020, Sabby exercised their remaining warrants and the Company received proceeds of $241,911. At present, with the receipt of the sale proceeds
from the closing on the 2020 Notes in October 2020, we have sufficient cash to fund planned operations into the second quarter of 2021. We continue to
evaluate options including the licensing of additional rights to commercialize our clinical products as well as raising capital through the capital markets.
However, our ability to raise additional capital raises significant concerns about our ability to continue as a going concern. Since inception, and through
December 31, 2020, we have an accumulated deficit of $109 million and we had cash and cash equivalents of $427,898 as of December 31, 2020. We
anticipate incurring additional operating losses in the future as we continue to explore the potential clinical benefits of Tß4-based product candidates over
multiple indications. We have entered into a series of strategic partnerships under licensing and joint venture agreements where our partners are responsible
for advancing development of our product candidates by sponsoring multiple clinical trials.

Current Clinical Status

In  January  2015,  we  entered  into  a  Joint  Venture  Agreement  with  GtreeBNT  whereby  we  created  ReGenTree  LLC  (“ReGenTree”  or  “Joint
Venture”) jointly owned by us and GtreeBNT, which intends to commercialize RGN-259 for treatment of dry eye syndrome and neurotrophic keratitis, an
orphan ophthalmic indication in the United States.

To date ReGenTree has sponsored a Phase 2/3 clinical trial (“ARISE-1”) and Phase 3 clinical trials in patients with DES (“ARISE-2”). Last year
ReGenTree  completed  a  Phase  3  clinical  trial  in  patients  with  neurotrophic  keratitis  (“NK”)  (“SEER-1”),  and  is  currently  sponsoring  a  Phase  3  trial
(“ARISE-3”)  in  patients  with  DES,  both  in  the  U.S.  In  May  2016,  we  reported  the  results  of  the  317-patient  ARISE-1  trial  and  in  October  2017,  we
reported the results of the ARISE-2 trial. The ARISE-2 study, which was sponsored by ReGenTree and managed by Ora, Inc. pursuant a contract between
the  parties,  demonstrated  a  number  of  statistically  significant  improvements  in  both  signs  and  symptoms  of  DES  with  0.1%  RGN-259  versus  placebo,
while showing excellent safety, comfort, and tolerability profiles. The ocular discomfort symptom showed a statistically significant reduction in the RGN-
259-treated group at day 15 as compared to placebo (p=0.0149) in the change from baseline. For sign, RGN-259 also improved the dry eye patient’s ability
to withstand an exacerbated condition in a patient subgroup with both compromised corneal fluorescein staining and Schirmer’s test at baseline. In this
population, RGN-259 showed superiority over placebo in reducing corneal fluorescein staining in the change from baseline at days 15 and 29 (p=0.0207
and 0.0254, respectively). RGN-259 confirmed its global effects on dry eye syndrome and fast onset in multiple sign and symptom efficacies with no safety
issues  in  the  ARISE-1  and  ARISE-2  studies  as  well  as  in  the  pooled  data,  although  ARISE-2  was  not  successful  in  duplicating  the  results  of  ARISE-1
where the study population was limited and less diversified. ReGenTree is proceeding with its RGN-259 development plan it discussed with the FDA in
April 2018. ReGenTree and Ora, Inc. have entered into a contract for management of ARISE-3 study. The first patient was enrolled in the second quarter of
2019 and the last patient was enrolled in October 2020. Due to the COVID-19 pandemic, the completion of ARISE-3 study was delayed from the original
timeline but the patent treatment and follow-up was completed in November as ReGenTree previously reported in clinicaltrials.gov. As of the date of this
filing, the patient database has been locked and topline results are expected shortly.

The NK trial (SEER-1), a smaller study in an orphan population, enrolled of 18 patients. On May 14, 2020, the Company reported that the trial
was closed and reported the results of SEER-1. Six out of 10 patients in the RGN-259 treated group and 1 out of 8 patients in the placebo treated group
achieved  complete  corneal  healing  in  four  weeks.  In  terms  of  the  primary  endpoint,  “ratio  of  corneal  wound  healed  patients  after  four  weeks'
administration”, the statistical difference was slightly over 0.05 (p = 0.0656, Fisher's exact test), due to the limited number of patients in each group. When
another  statistical  analysis  method  was  used  to  analyze  the  same  primary  endpoint  (Chi  square  test),  there  was  statistical  significance,  p  =  0.0400.  In
addition, in a pre-specified secondary endpoint evaluating corneal epithelial healing at day 43 (two weeks post-treatment) and the durability of RGN-259
treatment, we also confirmed a clear statistical difference using the Fisher's exact test, p = 0.0359. Several other efficacy parameters were either highly
significant or strongly trending toward statistical significance in the RGN-259 group indicating the depth of patient response to RGN-259.

GtreeBNT has developed the CMC (chemistry, manufacturing and controls) dossier required for Phase 3 clinical trials and commercialization in
the  U.S.  and  in  Korea.  This  comprehensive  and  critical  effort  ensures  that  final  drug  product  manufacturing,  packaging,  stability,  purity,
reproducibility, etc., meets regulatory guidelines and product specifications. The product of this activity is the current product formulation being utilized in
the U.S. trials being conducted by ReGenTree and will also be utilized in the planned clinical activity to be conducted by GtreeBNT under the RGN-259
license agreement for Pan Asia.

During the past several years, ReGenTree, LLC began developing a modified eye drop formulation that it believes will enhance the efficacy of
thymosin  beta  4  for  NK,  improve  the  patient  experience,  and  allow  a  proprietary  valued  orphan  product  price  for  this  rare  disease.  The  Company  has
completed a preliminary formulation for NK patients that will be considered for use in future clinical study. ReGenTree has not yet determined if it will use
this new formulation in the future for NK.

In February 2017, our licensee for RGN-137, GtreeBNT, through its subsidiary, Lenus Therapeutics, LLC, received permission from the FDA to
sponsor a Phase 3 clinical trial using RGN-137 to treat patients with epidermolysis bullosa (“EB”), a genetic disease that causes severe blistering of the
skin and internal organs. In August 2017, the Company amended the agreement for RGN-137 held by GtreeBNT. Under the amendment the Territory was
expanded to include Europe, Canada, South Korea, Australia and Japan. In December 2018, GtreeBNT initiated a small Phase 2 open trial in patients with
EB to evaluate RGN-137 in such patients prior to sponsoring a larger Phase 3 trial. Three patients have been enrolled in the open clinical trial to date. It
was reported in August 2019, that the first patient had positively responded to RGN-137. As of the date of this report, the Company has not been updated
as to current enrollment status.

Currently,  we  have  active  partnerships  in  four  major  territories:  North  America,  Europe,  China  and  Pan  Asia.  Our  partners  have  been  moving
forward and making progress in each territory. In each case, the cost of development is being borne by our partners with no financial obligation for the
Company.  We  still  have  significant  clinical  assets  to  develop,  primarily  RGN-352  (injectable  formulation  of Tß4  for  cardiac  and  CNS  disorders)  in  the
U.S., most of Asia, and Europe, and RGN-259 in the EU. In August 2017 we amended the RGN-137 license agreement with GtreeBNT, expanding the
territory to include Europe, Canada, South Korea, Australia and Japan. Regarding RGN-259, our goal is to wait until satisfactory results are obtained from
the current ophthalmic clinical program in the U.S. before moving into the EU. This should allow us to obtain a higher value for the asset at that time.
However, we intend to continue to develop RGN-352, our injectable systemic product candidate for cardiac and central nervous system indications and for
the  treatment  of  severe  symptoms  resulting  from  COVID-19  infection,  either  by  obtaining  grants  to  fund  a  Phase  2a  clinical  trials  or  finding  a  suitable
partner with the resources and capabilities to develop it as we have with RGN-259.

In March of 2020, the FDA changed the category under which thymosin beta 4 was regulated. Prior to this change, Tβ4 was regulated as a new
chemical entity. Now it is regulated as a biologic. Further details regarding this change the impact on the Company and its work to date is discussed further
in  this  report  (See  –  “Government  Regulation”  below).  We  anticipate  incurring  additional  operating  losses  in  the  future  as  we  continue  to  explore  the
potential clinical benefits of Tß4-based product candidates over multiple indications. To fund further development and clinical trials we have entered into a
series of strategic partnerships under licensing and joint venture agreements (see “Strategic Partnerships” below) where our partners are responsible for
advancing development of our product candidates with multiple clinical trials.

Overview of Tß4

Tß4 is a synthetic copy of a naturally occurring 43-amino acid peptide that was originally isolated from bovine thymus glands. It plays a vital role

in cell structure and motility and in the protection, regeneration, remodeling and healing of tissues.

Although it is recognized that wound healing and tissue regeneration are complex processes, most companies working to develop new drugs in
this area have focused primarily on the development of growth factors and genetic therapies to stimulate healing and have, to date, failed to demonstrate
dramatic  improvements  in  the  healing  process.  Numerous  preclinical  animal  studies,  published  by  independent  researchers,  have  identified  several
important  biological  activities  involving  Tß4  that  we  believe  make  it  potentially  useful  as  a  wound  healing,  repair  and  tissue  regenerating  agent.  These
activities include:

·

·

·

·

Progenitor (Stem) Cell Recruitment and Differentiation.  Independent research published in the journal Nature in November 2006 featured
the discovery that Tß4 is the key signaling molecule that recruits and triggers adult epicardial progenitor cells, or EPCs, to differentiate into
coronary  blood  vessels.  EPCs  are  partially  differentiated  stem  cells  that  can  further  differentiate  into  specific  cell  types  when  needed.
Confirmatory  research  published  in  2009  in  the  Journal  of  Molecular  and  Cellular  Cardiology  concluded  that  Tß4  is  responsible  for  the
initiation  of  the  embryonic  coronary  developmental  program  and  EPC  differentiation  in  adult  mice.  These  publications  confirm  that  Tß4’s
interaction  with  EPCs  is  necessary  for  the  maintenance  of  a  healthy  adult  animal  heart,  as  well  as  for  normal  embryo  and  fetal  heart
development  in  mammals.  In  Neuroscience  (2009  and  2010),  and  the  J.  Neurosurgery  (2010),  Tß4  was  shown  to  similarly  stimulate
oligodendrogenesis, i.e.,  the  differentiation  of  oligodendroctye  progenitor  cells  into  myelin-producing  oligodendrocytes,  whereby  restoring
functional recovery in animal models of multiple sclerosis, stroke, and traumatic brain injury.

Actin Regulation.  Tß4 regulates actin, which comprises up to 10% of the protein of non-muscle cells in the body and plays a central role in
cell  structure  and  in  the  movement  of  cells.  Independent  research  studies  have  indicated  that  Tß4  stimulates  the  migration  of  human
keratinocytes, or skin cells, as well as corneal epithelial cells that protect the eye, human endothelial cells and progenitor cells of the heart and
brain. Endothelial cells are the major cell type responsible for the formation of new blood vessels, a process known as angiogenesis. Certain
of these studies conducted at the National Institutes of Health, or NIH, were the first to suggest the role of Tß4 in wound healing. The data
from these studies encouraged us to license the rights to Tß4 from the NIH in 2001 and to launch an initial clinical development program that
targeted the use Tß4 for chronic dermal wounds.

Reduction  of  Inflammation  and  Scar  Tissue  Formation.    Uncontrolled  inflammation  is  the  underlying  basis  of  many  pathologies  and
injuries. Independent research has shown that Tß4 is a potent anti-inflammatory agent in skin cells and in corneal epithelial cells in the eye.
Tß4 has also been shown to decrease the levels of inflammatory mediators and to significantly reduce the influx of inflammatory cells in the
reperfused heart of animals. More recent preclinical research suggests that Tß4 blocks activation of the NFκB pathway, which is involved in
DNA activation of inflammatory mediators, thereby modulating inflammation in the body. This anti-inflammatory activity may explain, in
part, the mechanism by which Tß4 appeared to improve functional outcome in the mouse multiple sclerosis model described above, as well as
promoting repair in the heart and skin. In the skin, it has been shown to reduce scar formation by reduction of infiltration of myofibroblasts.
Identifying  a  factor  such  as  Tß4  that  reduces  scarring  and  blocks  activation  of  NFκB  suggests  that  Tß4  could  have  additional  important
therapeutic  applications  for  inflammation-related  diseases,  such  as  cancer,  osteoarthritis,  rheumatic  diseases,  autoimmune  diseases,
inflammatory pulmonary disease and pancreatitis.

Collagen  and  Laminin-5  Stimulation.    Tß4  has  a  number  of  additional  biological  activities  shown  to  reduce  inflammation,  stimulate  the
formation of collagen, and up-regulate the expression of laminin-5, a subepithelial basement membrane protein. Both collagen and laminin-5
are central to healthy tissue, wound repair and the prevention of disease. Laminin-5 promotes cell migration and maintains cell-cell and cell-
matrix contacts for intact tissues which are important for preventing fluid loss and bacterial infection.

5

 
 
 
 
 
 
 
 
 
 
·

Anti-Apoptosis.  Tß4 has been shown to prevent apoptosis, or programmed cell death, in two animal models and in two tissue types. In the
rodent  model,  corneal  apoptosis,  or  loss  of  corneal  epithelial  cells  leading  to  corneal  epithelial  thinning,  was  prevented  through  topical
administration of Tß4 eye drops. In the heart muscle of ischemic animal models, such as in mice and pigs, cell death was prevented by either
local or systemic administration of Tß4.

Tß4  has  shown  efficacy  in  heart  repair  and  regeneration  in  numerous  animal  models.  A  2004  paper  in  Nature  showed  that  it  could  reduce  the
lesion size, improve cardiac function and promote survival. The 2006 Nature publication mentioned above further concluded that Tß4’s interaction with
EPCs resulted in the formation of cardiomyocytes that repaired damaged myocardium, or heart tissue, in mice after an induced acute myocardial infarction,
or  AMI,  commonly  known  as  a  heart  attack.  Research  published  in  the  journal  Circulation  showed  Tß4’s  cardioprotective  effects  in  a  pig  ischemic-
reperfusion model. This pig model is accepted as an important model upon which to base human clinical research, as pigs are larger mammals, the anatomy
of the pig heart is similar to that of the human heart, and vascular response processes are completed five to six times faster in pigs than in humans, so that
long-term results can be obtained in a relatively short period of time. This research also identified Tß4’s interaction with EPCs as the underlying basis of
cardioprotection  through  the  differentiation  of  EPCs  into  cardiomyocytes,  yielding  statistically  significant  cardiac  functional  recovery  results  when
compared to the administration of placebo.

Similar  research  in  the  area  of  brain  and  central  nervous  system  tissues  also  showed  efficacy  of  repair  and  regeneration  was  published  in  the
journal  Neuroscience  in  2009.  This  publication  concluded  that  Tß4  triggered  the  differentiation  of  oligodendrocyte  progenitor  cells  to  form  myelin-
producing oligodendrocytes, which led to the remyelination of axons in the brain of mice with experimental autoimmune encephalomyelitis, or EAE. This
mouse model is an accepted small animal model for the study of multiple sclerosis. Research published in the Journal of Neurosurgery in 2010 and also in
the Journal of Neurological Science in 2014 showed that Tß4 could improve functional neurological outcome in an animal stroke model. A second study
was  published  in  the  Journal  of  Neurosurgery  in  2011  demonstrating  that  administration  of  Tß4  can  significantly  improve  histological  and  functional
outcomes  in  rats  with  traumatic  brain  injury,  or  TBI,  indicating  that  Tß4  has  considerable  therapeutic  potential  for  patients  with  TBI.  More  recently,
researchers studying Tß4 under a material transfer agreement (MTA) found that Tß4 had beneficial effects in animal models of peripheral neuropathy, one
of  the  major  complications  of  diabetes.  This  research  was  published  in  the  Journal  of  Neurobiology  of  Disease  in  December  2012  and  appears  to
corroborate previous findings using Tß4 for repair of central nervous system disorders. A paper in Neuropharmacology in 2014 found many benefits of Tß4
administration in a rat model of spinal cord injury, including decreased lesion size at 7 days, increased neural and oligodendrocyte survival, increase levels
of  myelin  basic  protein  (a  marker  of  mature  oligodendrocytes),  decreased  ED1  (a  marker  of  activated  microglia/macrophages),  and  decreased
proinflammatory  cytokines.  Thus,  Tß4  has  efficacy  for  repair  and  regeneration  in  several  nervous  system  injury  models  including  MS,  TBI,  stroke,
peripheral neuropathy, and spinal cord injury and there will likely be additional applications in this area. We believe that these various biological activities
work  in  concert  to  play  a  vital  role  in  the  healing  and  repair  of  injured  or  damaged  tissue  and  suggest  that  Tß4  is  an  essential  component  of  the  tissue
protection  and  regeneration  process  that  may  lead  to  many  potential  medical  applications.  All  of  our  product  candidates  utilize  Tß4  as  the  active
pharmaceutical ingredient (API), which is manufactured by solid-phase peptide synthesis and is an exact copy of the naturally occurring peptide. We have
created three distinct formulations for various routes of administration and medical indications.

Recently, a scientific paper was published by a multi-institutional team of scientists from eight American research centers published describing
new therapeutic approaches for COVID-19 in which they propose that Thymosin beta 4 (Tβ4), because of its ability to induce fibrinolysis, among other
activities, may be useful in treating patients with the COVID-19 virus. According to the scientific team, an increase of fibrinolysis could be achieved by
administering Tβ4. Fibrinolysis is the breakdown of fibrin in blood clots and Tβ4 has been shown to prevent actin from binding to fibrin, which is a major
component of blood clots. Blood clots in the blood stream and organs of patients with COVID-19 have been shown to lead to extensive morbidity and
patient death.

The researchers also found that COVID-19 elevates bradykinin levels in multiple tissues and systems that cause significant increases in vascular
dilation, vascular permeability, and hypotension in infected patients. Previous studies have shown that elevated bradykinin levels induce pain and cause
blood  vessels  to  expand  and  become  leaky,  that  can  lead  to  swelling  and  inflammation  of  the  surrounding  tissue. This  bradykinin-storm  in  COVID-19
patients induces leakage of fluid into the lungs and excessive release of hyaluronic acid preventing oxygen uptake and carbon dioxide release in the lungs
of  severely  affected  COVID-19  patients.  These  bradykinin-driven  outcomes  suggest  that  a  bradykinin  storm  may  be  responsible  for  many  of  the  more
severe symptoms of COVID.

The  researchers  also  looked  at  differences  in  male/female  morbidity  and  mortality  and  noted  a  number  of  interesting  points  linked  with  other
studies. It is known that older age and a high number of co-morbidities are associated with increased severity and mortality in patients with COVID-19 and
other similar infectious viruses such as SARS. They reported that age was comparable between men and women in all data sets. In the case data series,
men's cases tended to be more serious than women's (P = 0.035). In the public data set, the number of men who died from COVID-19 is 2.4 times that of
women  (70.3  vs.  29.7%,  P  =  0.016).  While  men  and  women  have  the  same  prevalence,  men  with  COVID-19  are  more  at  risk  for  worse  outcomes  and
death, independent of age.

That men with COVID-19 are 2.4 times more likely than women to die from the virus is extremely compelling because the gene for Thymosin
beta 4 resides on the X chromosome. Women have two X chromosomes while men only have one. As the researchers suggested, this could explain the
lower incidence of COVID-19 induced mortality in women because it is found on the X chromosome and escapes X-inactivation. Women, therefore, would
have increased levels of Tβ4 compared to men; thus, the possible explanation why women have an improved chance of survival. If true, then administering
pharmacological levels of Tβ4 to COVID-19 patients may significantly reduce morbidity and improve survival.

We believe the potential impact of Tβ4 in the treatment of COVID-19 merits further consideration as this, and other published studies, have shown
Tβ4's  ability  to  not  only  down-regulate  inflammatory  chemokines  and  cytokines  and  proinflammatory  processes  such  as  the  bradykinin  storm,  but  also
increase fibrinolysis and accelerate wound repair in the heart, lungs, kidneys and other organs that are often affected by COVID-19 infection. Moreover,
previously published data have demonstrated a significant decrease of Tβ4 in blood, tears, and saliva with age in humans. Thus, finding a way to control
and dampen this "bradykinin storm" may be important to successfully treating COVID-19 patients, especially in older and more vulnerable patients.

In March of 2020, the FDA changed the category under which thymosin beta 4 was regulated. Prior to this change, Tβ4 was regulated as a new
chemical entity. Now it is regulated as a biologic. Further details regarding this change the impact on the Company and its work to date is discussed further
in this report (See – “Government Regulation” below).

Our Product Candidates

RGN-259

RGN-259 is our proprietary preservative-free eye drop formulation of Thymosin beta 4. In September 2011, we completed a Phase 2a exploratory
clinical trial evaluating the safety and efficacy of RGN-259 in 72 patients with moderate dry eye syndrome. In November 2011, we reported preliminary
safety and efficacy results from the trial. RGN-259 was deemed safe and well-tolerated, with no observed drug-related adverse events.

In  June  2012,  we  reported  preliminary  results  from  a  double-masked,  vehicle-controlled,  physician-sponsored  Phase  2  clinical  trial  evaluating
RGN-259  for  the  treatment  of  nine  patients  (18  eyes)  with  severe  dry  eye.  RGN-259  was  observed  to  be  safe  and  well-tolerated  and  met  key  efficacy
objectives with statistically significant sign and symptom improvements, compared to vehicle control, at various time intervals, including 28 days post-
treatment.

Consistent with the reduction of ocular discomfort and fluorescein staining at the 28-day follow-up visit, other improvements seen in the RGN-
259-treated patients included tear film breakup time and increased tear volume production. Likewise, these improvements were seen at other time points in
the study. These results were published in Cornea in 2015.

In September 2015, ReGenTree began the Phase 2/3 ARISE-1 clinical trial in patients with DES and the Phase 3 SEER-1 clinical trial in patients
with  neurotrophic  keratopathy,  both  in  the  U.S.  In  May  2016,  we  reported  the  results  of  the  317-patient  ARISE-1  dry  eye  trial.  In  the  trial,  RGN-259
demonstrated statistically significant improvements in both signs and symptoms of dry eye with 0.05% and 0.1% RGN-259 compared to placebo in a dose
dependent  manner  during  a  28-day  dosing  period.  While  the  primary  outcome  measures  were  not  met,  several  key  related  pre-specified  endpoints  and
subgroups  of  patients  with  more  severe  dry  eye  showed  statistically  significant  treatment  effects.  These  results  confirm  the  findings  from  the  previous
Phase 2 trial providing clear direction for the clinical regulatory pathway and remaining registration trials for RGN-259. Shortly following the ARISE-1
trial, the FDA approved ReGenTree’s Phase 3, ARISE-2 dry eye protocol and we initiated the ARISE-2 trial that enrolled approximately 600 patients.

The  ARISE-2  study,  which  was  sponsored  by  ReGenTree  and  managed  by  Ora,  Inc.,  demonstrated  a  number  of  statistically  significant
improvements in both signs and symptoms of DES with 0.1% RGN-259 versus placebo, while showing excellent safety, comfort, and tolerability profiles.
The ocular discomfort symptom showed a statistically significant reduction in the RGN-259-treated group at day 15 as compared to placebo (p=0.0149) in
the change from baseline. In addition, RGN-259 also improved the dry eye patient’s ability to withstand an exacerbated condition in a patient subgroup
with  both  compromised  corneal  fluorescein  staining  and  Schirmer’s  test  at  baseline.  In  this  population,  RGN-259  showed  superiority  over  placebo  in
reducing corneal fluorescein staining in the change from baseline at days 15 and 29 (p=0.0207 and 0.0254, respectively). RGN-259 confirmed its global
effects on DES and fast onset in multiple sign and symptom efficacies with no safety issues in the ARISE-1 and ARISE-2 studies as well as in the pooled
data, although ARISE-2 was not successful in duplicating the results of ARISE-1 where the study population was limited and less diversified.

In February 2019, ReGenTree initiated the 700-patient ARISE-3 trial in patients with dry eye syndrome to confirm the results observed in ARISE-
2. The first patient was enrolled in the second quarter of 2019 and the last patient was enrolled in October 2020. Patient enrollment and treatment has been
completed and the patient database has been locked and topline results are expected shortly.

Strategic Partnerships

Lee’s Pharmaceutical. We are a party to a license agreement with Lee’s Pharmaceutical for the license of Thymosin Beta 4 in any pharmaceutical
form, including our RGN-259, RGN-352 and RGN-137 product candidates, in China, Hong Kong, Macau and Taiwan (Greater China). In February 2019,
the license was assigned by Lee’s to their affiliate, Zhaoke Ophthalmology Pharmaceutical Limited. Lee’s previously filed an IND with the Chinese FDA to
conduct a Phase 2, randomized, double-masked, dose-response clinical trial with RGN-259 in China for dry-eye syndrome. Lee's subsequently informed us
that it received notice from China's FDA declining its IND application for a Phase 2 dry eye clinical trial because the API was manufactured outside of
China. The API was manufactured in the U.S. and provided to Lee's by RegeneRx pursuant to the agreement to develop RGN-259 ophthalmic eye drops in
Greater China. However, in mid-2016, we were informed by Lee’s that the CFDA modified its manufacturing regulations and would now allow Chinese
companies to utilize API manufactured outside of China for Phase 1 and 2 clinical trials. Recently, we have been in ongoing discussions with management
of Zhaoke to further refine its development plan for RGN-259. We have not yet been informed of a projected starting date for Phase 2 trials but believe
Lee’s  intends  to  await  the  outcome  of  the  ARISE-3  DES  trial  prior  to  initiating  clinical  trials  in  China.  Lee’s  has  assigned  the  license  to  its  subsidiary
Zhaoke Ophthalmology Pharmaceutical Limited for development of RGN-259 in China and is in the process of funding this development.

GtreeBNT.  We  are  a  party  to  a  license  agreement  with  GtreeBNT  for  the  license  of  RGN-259  related  to  certain  development  and
commercialization rights for RGN-259, in Asia (excluding Greater China). Separately, we licensed GtreeBNT the rights to RGN-137 which was recently
amended as discussed above. GtreeBNT is currently our second largest stockholder. GtreeBNT filed an IND with the Korean Ministry of Food and Drug
Safety to conduct a Phase 2/3 study with RGN-259 in patients with dry eye syndrome and in July 2015 received approval to conduct the trial. In late 2016
GtreeBNT informed us that it believes marketing approval in the U.S. will allow expedited marketing in Korea, possibly without the need for a clinical trial
and, therefore, will await marketing approval in the U.S.

U.S.  Joint  Venture  (ReGenTree,  LLC).  In  January  2015,  we  entered  into  a  Joint  Venture  Agreement  with  GtreeBNT  whereby  we  created
ReGenTree, jointly owned by us and GtreeBNT, which will commercialize RGN-259 for treatment of dry eye and NK, an orphan indication in the United
States. We are entitled to royalties as a percentage of net sales ranging from single digits to low double digits based on the medical indications approved
and whether the Joint Venture commercializes products directly or through a third party. RegeneRx possesses one of three board seats of ReGenTree and
certain  major  decisions  and  transactions  within  ReGenTree,  such  as  commercialization  strategy,  mergers,  and  acquisitions,  require  RegeneRx’s  board
designee’s consent. We currently hold a 38.5% ownership interest in ReGenTree. This ownership interest may be further reduced to as low as 25% once
ReGenTree obtains FDA approval of a BLA (formerly a NDA) for dry eye syndrome in the U.S. In the event ReGenTree is acquired, or a change of control
occurs  following  achievement  of  n  BLA,  RegeneRx  shall  be  entitled  to  a  minimum  of  40%  of  all  proceeds  paid  or  payable  and  will  forgo  any  future
royalties.

RGN-352

During  2009,  we  completed  a  Phase  1a  and  Phase  1b  clinical  trial  evaluating  the  safety,  tolerability  and  pharmacokinetics  of  the  intravenous
administration of RGN-352 in 60 healthy subjects (40 in each group, 20 of whom participated in both phases). Based on the results of these Phase 1 trials
and extensive preclinical efficacy data published in peer-reviewed journals, in the second half of 2010, we began start-up activities for a Phase 2 study to
evaluate RGN-352 (Tß4 injectable solution) in patients who had suffered an AMI. We had planned to begin enrolling patients in this clinical trial in the
second  quarter  of  2011.  However,  in  March  2011,  we  were  notified  by  the  FDA  that  the  trial  was  placed  on  clinical  hold  as  a  result  of  our  contract
manufacturer’s  alleged  failure  to  comply  with  the  current  Good  Manufacturing  Practices  (cGMP)  regulations.  The  manufacturer  has  since  closed  its
manufacturing facility. The FDA prohibited us from using any of the active drug or placebo formulated by this manufacturer in human trials; consequently,
we must have study drug (RGN-352 and RGN-352 placebo) manufactured by a new cGMP-compliant manufacturer in the event we seek to move forward
with this trial. While we have identified a qualified manufacturer for RGN-352, we elected to postpone activities on this trial until the requisite funding or a
partner is secured.

In  addition  to  the  potential  application  of  RGN-352  for  the  treatment  of  cardiovascular  disease,  preclinical  research  published  in  the  scientific
journals Neuroscience and the Journal of Neurosurgery, among numerous others, indicates that RGN-352 may also prove useful for patients with multiple
sclerosis, or MS, as well as patients suffering a stroke, traumatic brain injury, peripheral neuropathy, or spinal cord injury. In these preclinical studies, the
administration  of  Tß4  resulted  in  regeneration  of  neuronal  tissue  by  promoting  remyelination  of  axons  and  stimulating  oligodendrogenesis,  resulting  in
improvement  of  neurological  functional  activity.  In  2012,  researchers  studying  Tß4  under  a  material  transfer  agreement  (MTA)  found  that  Tß4  had
beneficial  effects  in  animal  models  of  peripheral  neuropathy,  one  of  the  major  complications  of  diabetes.  This  research  was  published  in  the  journal  of
Neurobiology of Disease in 2012 and appears to corroborate previous findings using Tß4 for repair of central nervous system disorders. We are discussing
possible partnership opportunities with companies interested in developing RGN-352 for this indication.

Based  on  our  Phase  1  data  and  the  preclinical  research  discussed  above,  we  are  evaluating  various  opportunities  for  government  funding  for  a
Phase  2a  clinical  trial  to  show  proof-of-concept  in  each  case  while  also  talking  with  prospective  strategic  partners  with  the  interest,  capabilities  and
resources  to  further  develop  product  candidate  in  these  fields.  We  have  also  been  evaluating  the  potential  of  RGN-352  for  the  treatment  of  COVID-19
based on scientific data describe above.

In March of 2020, the FDA changed the category under which thymosin beta 4 was regulated. Prior to this change, Tβ4 was regulated as a new
chemical entity. Now it is regulated as a biologic. Further details regarding this change the impact on the Company and its work to date is discussed further
in this report (See – “Government Regulation” below).

RGN-137

Clinical Development — Epidermolysis Bullosa (EB).  Starting in 2005, we began conducting a Phase 2 clinical trial designed to assess the safety
and effectiveness of RGN-137 for the treatment of patients with EB. EB is a genetic disease of approximately 10 gene mutations that results in fragile skin
and other epithelial structures (e.g., cornea and GI tract) that can blister spontaneously or separate at the slightest trauma or friction, creating a wound that
at times does not heal or heals poorly. In severe cases, recurrent blistering and tissue loss may be life threatening. EB has been designated as an “orphan”
indication  by  the  FDA’s  Office  of  Orphan  Drugs.  We  closed  the  Phase  2  trial  in  late  2011  and  we  submitted  the  final  report  to  the  FDA  in  2014.  In
February 2017, GtreeBNT, our licensee for RGN-137, received permission from the U.S. FDA to sponsor a Phase 3 clinical trial using RGN-137 to treat
patients with EB. Recently, the FDA modified efficacy requirements in EB patients from complete wound closing to partial wound closing, which has had a
positive impact on clinical trial design. Our licensee initiated a Phase 2 open clinical trial on EB patients in the U.S. in December 2018, and 3 of 15 patients
have been enrolled to date. While the trial has been ongoing, due to the COVID-19 pandemic, it is unclear when enrollment will resume.

Clinical  Development  —  Pressure  Ulcers.    In  late  2005,  we  began  conducting  a  Phase  2  clinical  trial  designed  to  assess  the  safety  and
effectiveness of RGN-137 for the treatment of patients with chronic pressure ulcers, commonly known as bedsores.In January 2009, we reported final data
from this trial. RGN-137 was well-tolerated at all three dose levels studied, with no dose-limiting adverse events, which achieved the primary objective of
the study. A follow-on evaluation, reported at the 3rd International Symposium on the Thymosins in Health and Disease in March 2012, showed that for
those pressure ulcer patients’ wounds that healed, RGN-137 mid dose (0.02% Tβ4 gel product) accelerated wound closure with a median time to healing of
22 days as compared to 57 days for the placebo. Although those results were clinically significant, they were not statistically significant.

Clinical  Development  —  Venous  Stasis  Ulcers.  In  mid-2006  we  began  conducting  a  Phase  2  clinical  trial  designed  to  assess  the  safety  and
effectiveness of RGN-137 for the treatment of patients with venous stasis ulcers. Venous stasis ulcers are a common type of chronic wound that develops
on the ankle or lower leg in patients with chronic vascular disease. In these patients’ blood flow in the lower extremities is impaired leading to venous
hypertension, edema (swelling) and mild redness and scaling of the skin that gradually progresses to ulceration. In 2009, we reported final data from that
trial. Those results were both clinically and statistically significant.

Our Strategy

We seek to maximize the value of our product candidates by advancing their clinical development and then identifying suitable partners for further
development,  regulatory  approval,  and  marketing.  We  intend  to  engage  in  strategic  partnerships  with  companies  with  clinical  development  and
commercialization strengths in desired pharmaceutical therapeutic fields. We are actively seeking partners with suitable infrastructure, expertise and a long-
term initiative in our medical fields of interest. Our ability to locate and engage new strategic partners has been limited by the global COVID pandemic.
Historically, we have entered the licensing and joint ventures discussed above. We continue to control the cardiovascular and neurovascular assets (RGN-
352) in the EU and are able to consolidate them with similar assets in the U.S. and other territories in Asia to create a worldwide portfolio that we believe
will be more attractive to multi-national pharmaceutical companies.

We use a major contract manufacturer to produce bulk Tß4, which is the active pharmaceutical ingredient (API) in our product candidates by an
established and proven manufacturing process known as solid-phase peptide synthesis. While we do not currently have long-term supply agreements in
place, we and ReGenTree intend to establish a long-term supply arrangement with at least one manufacturer once practicable. No assurance can be given,
however, that future agreements by us or our partners will be negotiated on favorable terms, or at all. Contractors are selected on the basis of their supply
capability, ability to produce a product in accordance with Current Good Manufacturing Practice, or cGMP, requirements of the FDA and ability to meet
our established specifications and quality requirements. Given our recent licensing and joint venture deals, our partner in Korea and the U.S. are working
closely  with  our  current  primary  contract  manufacturer  on  the  cGMP  validation  process  and  consistency  runs,  among  other  things,  to  prepare  for  the
manufacture  of  bulk  Tß4  for  use  in  future  clinical  trials  and  commercialization  of  our  formulated  product  candidates. Through  ReGenTree  we  are  also
identifying and qualifying other potential API manufacturers. We will have access to the data resulting from this endeavor should we need to use it for
purposes outside the licensed territories.

9

 
 
 
 
 
 
 
 
 
 
 
We and our licensees also use a number of outside contract manufacturers to formulate bulk Tß4 into our product candidates, RGN-137, RGN-259
and  RGN-352.  We  use  separate  manufacturers  for  each  formulation  of  Tß4.  All  of  these  formulations  may  require  modifications,  along  with  additional
studies, as we advance our clinical development programs through commercialization.

Competition

We are engaged in a business that is highly competitive, and our target medical indications are ones with significant unmet needs. Consequently,
there are many enterprises, both domestic and foreign, pursuing therapies and products that could compete with ours. Most of these entities have financial
and human resources that are substantially greater than ours, specifically with regard to the conduct of clinical research and development activities, clinical
testing and in obtaining the regulatory approvals necessary to market pharmaceutical products. Brief descriptions of some of these competitive products
follow:

RGN-259.    Most  specialty  ophthalmic  companies  have  a  number  of  products  on  the  market  that  could  compete  with  RGN-259.  There  are
numerous antibiotics to treat eye infections to promote corneal wound healing and many eye lubrication products that are soothing to the eye and help eye
healing, many of which are sold without prescriptions. Companies also market steroids to treat certain conditions within our area of interest. Allergan, Inc.
markets  Restasis®,  Ophthalmic  Emulsion,  an  FDA-approved  eye  drop  used  to  treat  dry  eye.  Restasis,  and  other  products,  have  been  approved  for
marketing in certain other countries where we have licensed RGN-259. Novartis is marketing the recently FDA-approved product, Xiidra®. We believe
RGN-259 is different from Restasis® and Xiidra® and any other product or product candidate available for dry eye in that it actively promotes repair using
a  multi-faceted  approach  of  increasing  cell  migration  and  laminin-5  production,  and  decreasing  inflammation  and  apoptosis,  without  any  noted  adverse
effects.

In  2018,  Dompé  Farmaceutici  S.p.A.  announced  FDA  approval  of  Oxervate™  to  treat  patients  with  neurotrophic  keratitis.  Oxervate™  is
manufactured using a recombinant form of human nerve growth factor. It is used six times per day for two months and monthly treatment costs can be as
high as $46,760 for one eye according to The Balance, a lifestyle journal covering health care trends and costs. Patients have reported eye pain, corneal
deposits,  foreign  body  sensation  and  inflammation,  among  other  side  effects  associated  with  Oxervate™.  We  believe  that  RGN-259  is  different  from
Oxervate™ in that it is faster acting, shows no adverse effects, and would likely be far less expensive.

In October 2020, the FDA approved loteprednol etabonate ophthalmic suspension (Eysuvis; Kala Pharmaceuticals) a 0.25% ocular corticosteroid
indicated for dry eye disease. As with other ophthalmic corticosteroids, Eysuvis is contraindicated in most viral diseases of the cornea and conjunctiva and
also  in  mycobacterial  infection  of  the  eye  and  fungal  diseases  of  ocular  structures.  Other  warnings  on  the  label  include  delayed  healing  and  corneal
perforation, intraocular pressure (IOP) increase, cataracts, bacterial, viral, and fungal infections.

RGN-352.  Currently, we do not believe there are any approved pharmaceutical products for regenerating cardiac tissue following a heart attack,
nor for regeneration of nervous tissue or for the remyelination of axons of patients with multiple sclerosis or patients suffering from traumatic brain injury.
However, many pharmaceutical companies and research organizations are developing products, pharmacologic and stem cell therapies and technologies
that  are  intended  to  prevent  cardiac  damage,  improve  cardiac  function,  and  regenerate  cardiac  muscle  after  a  heart  attack.  There  are  also  companies
developing products that are purported to remyelinate neurons and provide functional improvement for patients suffering from multiple sclerosis, stroke,
traumatic brain injury, and peripheral neuropathy. If we, or a partner, were to successfully develop RGN-352 for cardiovascular or central nervous system
indications, such products would have to compete with other drugs or therapies currently being developed or marketed by large pharmaceutical companies
for similar indications.

RGN-137.   There are numerous companies developing new pharmaceutical products for wound healing and for EB, in particular. Products and
therapies such as antibiotics, honey-based ointments, silver-based compounds and low frequency cavitational ultrasound are also used to treat certain types
of dermal wounds. Moreover, dermal wound healing is a large and highly fragmented marketplace that includes numerous therapeutic products and medical
devices for treating acute and chronic dermal wounds. Most recently, various other companies are attempting to develop genetic therapies to try to heal or
prevent serious wound disorders.

Government Regulation

In the United States, the Federal Food, Drug, and Cosmetic Act, as amended, or FFDCA, and the regulations promulgated thereunder, and other
federal and state statutes and regulations govern, among other things, the testing, manufacturing, labeling, storing, recordkeeping, distribution, advertising
and promotion of our product candidates. Regulation by governmental authorities in the United States and foreign countries will be a significant factor in
the  manufacturing  and  potential  marketing  of  our  product  candidates  and  in  our  ongoing  research  and  product  development  activities.  Any  product
candidate we develop will require regulatory approval by governmental agencies prior to commercialization. In particular, human therapeutic products are
subject  to  rigorous  preclinical  studies,  clinical  trials  and  other  approval  procedures  by  the  FDA  and  similar  health  authorities  in  foreign  countries.  The
process  of  obtaining  these  approvals  and  subsequent  compliance  with  appropriate  federal  and  state  statutes  and  regulations  requires  the  expenditure  of
substantial resources.

Preclinical  studies  must  ordinarily  be  conducted  to  evaluate  an  investigational  new  drug’s  potential  safety  by  toxicology  studies  and  potential
efficacy  by  pharmacology  studies.  The  results  of  these  studies,  among  other  things,  are  submitted  to  the  FDA  as  part  of  an  Investigational  New  Drug
Application,  or  IND,  which  must  be  reviewed  by  the  FDA  before  clinical  trials  can  begin.  Typically,  clinical  evaluation  involves  a  three-stage  process.
Phase  1  clinical  trials  are  conducted  with  a  small  number  of  healthy  volunteers  to  determine  the  safety  profile  and  the  pattern  of  drug  absorption,
distribution,  metabolism  and  excretion,  and  to  assess  the  drug’s  effect  on  the  patient.  Phase  2,  or  therapeutic  exploratory,  trials  are  conducted  with
somewhat larger groups of patients, who are selected by relatively narrow criteria yielding a more homogenous population that is afflicted with the target
disease, in order to determine preliminary efficacy, optimal dosages and expanded evidence of safety. Phase 2 trials should allow for the determination of
the dose to be used in Phase 3 clinical trials. Phase 3, or therapeutic confirmatory, large scale, multi-center, comparative trials are conducted with patients
afflicted  with  a  target  disease  in  order  to  provide  enough  data  for  the  statistical  proof  of  safety  and  efficacy  required  by  the  FDA  and  other  regulatory
authorities. The primary objective of Phase 3 clinical trials is to show that the drug confers therapeutic benefit that outweighs any safety risks. All clinical
trials must be registered with a central public database, such as www.clinicaltrials.gov, and once completed, results of the clinical trials must be entered in
the database.

Previously, thymosin beta 4 was regulated as a new chemical entity under the FDA’s Center for Drug Evaluation and Research (“CDER”). On
March 23, 2020, a new requirement under the Biologics Price Competition and Innovation Act of 2009 (BPCI Act) was enacted requiring that polypeptides
larger  than  40  amino  acids  in  length,  such  as  thymosin  beta  4  (Tβ4),  be  regulated  as  biologics  under  the  FDA’s  Center  for  Biologics  Evaluation  and
Research (“CBER”). Other such products formerly regulated as drugs, and now as biologics, include insulin and insulin analogs, human growth hormone,
pancreatic  enzymes,  and  reproductive  hormones.  While  the  requirements  of  a  BLA  are  very  similar  to  those  of  an  NDA,  the  FDA  could  require  the
Company to perform additional non-clinical testing or even repeat phase 1 in humans under these new regulations.

Unlike  the  previous  five-year  exclusive  period  for  new  chemical  entities  approved  under  an  NDA,  section  7002  of  the  Patient  Protection  and
Affordable Care Act (PPACA) provides 12 years of exclusivity for products approved under a BLA. Biologics can also receive orphan drug and pediatric
exclusivities. Therefore, if RGN-259 receives a license under a BLA, and with the Tβ4 patents already secured in the U.S, our exclusive market position
should be strengthened.

The results of these preclinical studies and clinical trials, along with detailed information on manufacturing, are submitted to the FDA in the form
of  a  Biologics  License  Application,  or  BLA,  for  approval  to  commence  commercial  sales.  In  responding  to  a  BLA,  the  FDA  may  refuse  to  file  the
application if the FDA determines that the application does not satisfy its regulatory approval criteria, request additional information or grant marketing
approval. Therefore, even if we complete Phase 3 clinical trials for our product candidates and submit a BLA to the FDA, there can be no assurance that the
FDA  will  grant  a  marketing  license,  or  if  granted,  that  it  will  be  granted  on  a  timely  basis.  If  the  FDA  does  grant  a  BLA,  it  may  require,  among  other
things,  post-marketing  testing,  including  potentially  expensive  Phase  4  trials,  which  monitor  the  safety  of  the  drug.  In  addition,  the  FDA  may  in  some
circumstances impose risk evaluation and mitigation strategies that may be difficult and expensive to administer. Product approvals may be withdrawn if
compliance with regulatory requirements is not maintained or if problems occur after the product reaches the market.

Among the conditions for a BLA is the requirement that the applicable clinical, pharmacovigilance, quality control and manufacturing procedures
conform  on  an  ongoing  basis  with  current  Good  Clinical  Practices,  Good  Laboratory  Practices,  current  Good  Manufacturing  Practices,  and  computer
information  system  validation  standards.  During  the  review  of  a  BLA,  the  FDA  will  perform  a  pre-licensing  inspection  of  select  clinical  sites,
manufacturing  facilities  and  the  related  quality  control  records  to  determine  the  applicant’s  compliance  with  these  requirements.  To  assure  compliance,
applicants  must  continue  to  expend  time,  money  and  effort  in  the  area  of  training,  production  and  quality  control.  After  approval  of  any  product,
manufacturers are subject to periodic inspections by the FDA. If a company fails to comply with FDA regulatory requirements, FDA may pursue a wide
range of remedial actions, including seizure of products, corrective actions, warning letters and fines.

We have received orphan drug designation from the FDA for RGN-137 for the treatment of EB and RGN-259 for the treatment of neurotrophic
keratitis or NK, (now to be developed by ReGenTree). The FDA may designate a product or products as having orphan drug status to treat a disease or
condition that affects less than 200,000 individuals in the United States, or, if patients of a disease number more than 200,000, the sponsor can establish
that it does not realistically anticipate its product sales will be sufficient to recover its costs. If a product candidate is designated as an orphan drug, then the
sponsor may receive incentives to undertake the development and marketing of the product, including grants for clinical trials, as well as a waiver of the
user fees for submission of a BLA.

11

 
 
 
 
 
 
 
 
 
 
Generally, if a product with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such
designation, the product is entitled to marketing exclusivity for a period of seven years in the United States and ten years in the EU. There may be multiple
designations of orphan drug status for a given drug and for different indications. Orphan drug designation does not guarantee that a product candidate will
be approved by the FDA for marketing for the designation, and even if a sponsor of a product candidate for an indication for use with an orphan drug
designation is the first to obtain FDA approval of a BLA for that designation and obtains marketing exclusivity, another sponsor’s application for the same
drug product may be approved by the FDA during the period of exclusivity if the FDA concludes that the competing product is clinically superior. In this
instance, the orphan designation and marketing exclusivity originally granted would be lost in favor of the clinically superior product.

Intellectual Property

We  hold  worldwide  patents  and  patent  applications  covering  peptide  compositions,  uses  and  formulations  related  to  dermal  and  ophthalmic
indications and other organ and tissue repair activities. In 2001, we entered into a license agreement with the NIH under which we received an exclusive
worldwide license from the NIH for all claims within the scope of the NIH’s patent application, and any issued patents, covering the use of Tß4 as a tissue
repair and regeneration factor. In 2007, patents were issued in Europe and the United States related to the original NIH patent application. These patents
expired in July 2019. Corresponding patents have also been granted in Hong Kong, Australia and China and certain other territories. The issued European
patent  was  opposed  by  a  third  party  at  the  European  Patent  Office  and,  in  December  2009,  we  argued  the  case  before  the  Opposition  Division  of  the
European Patent Office in Munich, Germany and prevailed with certain amendments to the claims. In exchange for the exclusive license, we agreed to
make certain minimum royalty and milestone payments to the NIH. This license agreement expired with the last of the issued patents. The expiration of the
patents and license has no impact on our current programs.

We hold a U.S. patent relating to the use of Tß4 for the treatment of congestive heart failure. This patent was issued in January 2012. In 2006, we
were issued a patent in China for the use of Tß4 to treat EB. We also hold two patents for the treatment of dry eye in the U.S. or through our in-license from
Henry  Ford  Hospital  System  patents  for  certain  neuro  disorders,  as  well  as  peripheral  neuropathy.  Other  patent  applications  for  our  various  product
candidates, if issued, will offer protection in the U.S. and certain other territories through 2033.

We, and our partners, have also filed additional U.S. and international patent applications covering various compositions, uses, formulations and
other components of Tß4, as well as for novel peptides resulting from our research efforts, the latest of which were filed during 2015. There can be no
assurance that these, or any other future patent applications under which we have rights, will result in the issuance of a patent or that any patent issued will
not be subject to challenge or opposition. In the case of a claim of patent infringement by or against us, there can be no assurance that we will be able to
afford the expense of any litigation that may be necessary to enforce our proprietary rights or that relevant patents will not expire prior to approval of any
of our product candidates.

We continuously evaluate our patents and patent applications in certain territories to determine whether it is cost-effective to continue to maintain
or prosecute them. In some cases, we have determined that the value or potential value of such patents and/or applications is not worth the continued effort
or  expense  and  have  either  ceased  efforts  to  pursue  specific  patents  or  abandoned  any  that  have  short  expiries  or  cover  countries  of  minimal  strategic
interest to us or our partners. We will continue to evaluate our portfolio and take such actions from time to time as appropriate.

Material Agreements

Lee’s Pharmaceuticals

On  July  15,  2012,  we  entered  into  a  license  agreement  with  Lee’s  Pharmaceutical  for  the  license  of  Tß4  in  any  pharmaceutical  formulation,
including  our  RGN-259,  RGN-352  and  RGN-137  product  candidates,  in  China,  Hong  Kong,  Macau  and  Taiwan.  The  terms  of  the  agreement  include
aggregate potential milestone payments of up to $3.6 million and royalties ranging from low double digit to high single digit royalties on commercial sales,
if  any.  Under  the  agreement,  Lee’s  is  responsible  for  all  developmental  costs  associated  with  each  product  candidate.  We  provided  Tß4  to  Lee’s  at  no
charge for a Phase 2 ophthalmic clinical trial and will provide Tß4 to Lee’s for all other developmental and clinical work at a price equal to our cost.

Lee’s originally filed an investigational new drug application IND with the Chinese FDA to conduct a Phase 2, randomized, double-masked, dose-
response clinical trial with RGN-259 in China for dry-eye syndrome. Lee’s subsequently informed us that it received notice from China's FDA (CFDA)
declining its investigational new drug (IND) application for a Phase 2b dry eye clinical trial because the API (active pharmaceutical ingredient or Tß4) was
manufactured outside of China. The API was manufactured in the U.S. and provided to Lee's by RegeneRx pursuant to a license agreement to develop
RGN-259 ophthalmic eye drops in the licensed territory. However, in mid-2016, we were informed by Lee’s that the CFDA modified its manufacturing
regulations and will now allow Chinese companies to utilize API manufactured outside of China for Phase 1 and 2 clinical trials. In February 2019, the
agreement was amended and assigned by Lee’s to their affiliate, Zhaoke Ophthalmology Pharmaceutical Limited. There are no economic changes to the
agreement. Recently, we have been in discussions with management of Zhaoke to further refine its development plan for RGN-259. We have not yet been
informed of a projected starting date for Phase 2 trials, but we believe Lee’s is awaiting the outcome of the ARISE-3 DES trial prior to initiating clinical
trials in China.

GtreeBNT

On March 7, 2014, we entered into license agreements with GtreeBNT Co., Ltd. The two licensing agreements are for the license of territorial

rights to two of our Thymosin Beta 4-based products candidates, RGN-259 and RGN-137.

Under the agreement for RGN-259, our preservative-free eye drop product candidate, GtreeBNT will have the right to develop and commercialize
RGN-259  in  Asia  (excluding  Greater  China).  The  rights  will  be  exclusive  in  Korea,  Japan,  Australia,  New  Zealand,  Brunei,  Cambodia,  East
Timor, Indonesia, Laos, Malaysia, Mongolia, Myanmar (Burma), Philippines, Singapore, Thailand, Vietnam, and Kazakhstan, and semi-exclusive in India,
Pakistan,  Bangladesh,  Bhutan,  Maldives,  Nepal,  Sri  Lanka,  Kyrgyzstan,  Tajikistan,  Turkmenistan  and  Uzbekistan,  collectively,  the  Territory  (the  “259
Territory”  or  Pan  Asia).  Under  the  agreement  for  RGN-259  we  are  eligible  to  receive  aggregate  potential  milestone  payments  of  up  to  $3.5  million.  In
addition, we are eligible to receive royalties of a low double-digit percentage of any commercial sales of the licensed product sold by GtreeBNT in the 259
Territory.

Under  the  license  agreement  for  RGN-137,  our  topical  dermal  gel  product  candidate,  GtreeBNT  will  have  the  exclusive  right  to  develop  and
commercialize  RGN-137  in  the  U.S.  (the  “137  Territory”).  Under  the  agreement  for  RGN-137  we  are  eligible  to  receive  aggregate  potential  milestone
payments of up to $3.5 million. In addition, we are eligible to receive royalties of a low double-digit percentage of any commercial sales of our licensed
product sold by GtreeBNT in the 137 Territory. Under an amendment to the agreement for RGN-137, for which we were compensated, the 137 Territory
was expanded to include Europe, Canada, South Korea, Australia and Japan.

Both the license agreement for RGN-137 and the license agreement for RGN-259 contain diligence provisions that require the initiation of certain
clinical trials within certain time periods that, if not met, would result in the loss of rights or exclusivity in certain countries. GtreeBNT will pay for all
developmental costs associated with each product candidate. We will also have the right to exclusively license any improvements made by GtreeBNT to
our products outside of the licensed territory on a royalty-free basis.

The  two  firms  have  created  a  joint  development  committee  and  continue  to  discuss  and  the  development  of  the  licensed  products  and  share
information  relating  thereto.  Both  companies  will  also  share  all  non-clinical  and  clinical  data  and  other  information  related  to  the  development  of  the
licensed product candidates.

ReGenTree - U.S. Joint Venture

On  January  28,  2015,  we  entered  into  the  Joint  Venture  Agreement  with  GtreeBNT,  a  shareholder  in  the  Company  and  licensee  in  certain  Pan
Asian  countries.  The  Joint  Venture  Agreement  provides  for  the  creation  of  the  Joint  Venture,  ReGenTree,  LLC  (“ReGenTree”),  jointly  owned  by  the
Company and GtreeBNT that will commercialize RGN-259 for treatment of dry eye and neurotrophic keratitis in the United States, as well as any other
relevant ophthalmic indications.

GtreeBNT  is  solely  responsible  for  funding  all  of  the  product  development  and  commercialization  efforts  of  ReGenTree.  GtreeBNT  made  an
initial contribution of $3 million in cash and received an initial equity stake of 51%. RegeneRx received and initial equity stake of 49% of ReGenTree.
GtreeBNT’s  equity  stake  may  increase  (and  RegeneRx’s  would  proportionally  decrease)  upon  ReGenTree  achieving  certain  product  development
milestones (including receipt of a new biologics license application “BLA” by the U.S. FDA). GtreeBNT has subsequently funded the initial Phase 2b/3
and the ongoing Phase 3 U.S. clinical trials for dry eye syndrome and neurotrophic keratitis, respectively.

Our initial ownership interest in ReGenTree was 49% and was reduced to 38.5% after filing of the final clinical study report with the FDA for the
Phase 3 trial for Dry Eye Syndrome completed in 2017. Based on when, and if, ReGenTree achieves certain additional development milestones in the U.S.
with RGN-259, our equity ownership may be incrementally reduced to between 38.5% and 25%, with 25% being the final equity ownership upon FDA
approval of an BLA for Dry Eye Syndrome in the U.S. In addition to our equity ownership, RegeneRx retains a royalty on net sales that varies between
single and low double digits, depending on whether commercial sales are made by ReGenTree or a licensee. In the event the ReGenTree entity is acquired
or there is a change of control that occurs following achievement of an BLA, RegeneRx shall be entitled to a minimum of 40% of all proceeds paid or
payable and will forgo any future royalties.

The Company is not required or otherwise obligated to provide financial support to ReGenTree.

ReGenTree  is  controlled  by  a  Board  of  Directors  consisting  of  three  members,  one  of  which  must  be  from  RegeneRx.  Certain  critical  matters
require  unanimous  board  approval,  including  merger,  consolidation,  or  sale  of  the  JV,  transfer  or  licensing  of  any  intellectual  property,  incurring
indebtedness, and entering into any material agreements, among others.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
ReGenTree is responsible for executing all development and commercialization activities under the Joint Venture Agreement, which activities will
be directed by a joint development committee comprised of representatives of the Company and GtreeBNT. The agreement has a term that extends to the
later of the expiration of the last patent covered by the agreement or 25 years from the first commercial sale under the agreement. The agreement may be
earlier terminated if the Joint Venture fails to meet certain commercialization milestones, or if either party breaches the Joint Venture Agreement and fails
to cure such breach, or as a result of government action that limits the ability of the Joint Venture to commercialize the product, as a result of a challenge to
a licensed patent, following termination of the license between the Company and certain agencies of the United States federal government, or upon the
bankruptcy of either party.

Development Agreements

While we are not currently directly engaged in development activities, historically we have entered into agreements with outside service providers
for the manufacture and development of Tß4, the formulation of Tß4 into our product candidates, the conduct of nonclinical safety, toxicology and efficacy
studies in animal models, and the management and execution of clinical trials in humans. Terms of these agreements vary in that they can last from a few
months  to  more  than  a  year  in  duration.  For  additional  information  regarding  our  research  and  development  expenses  over  the  past  two  years,  see
“Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations” in this report.

Employees

We  currently  have  three  full  time  employees  including  our  President  and  CEO  and  one  part  time  financial,  accounting  and  SEC  compliance

consultant. We also retain three independent contractors. We believe that we have good relations with our employees and contractors.

Corporate Information

We  were  incorporated  in  Delaware  in  1982  under  the  name  Alpha  1  Biomedicals,  Inc.  In  2000,  we  changed  our  corporate  name  to  RegeneRx
Biopharmaceuticals,  Inc.  Our  principal  executive  office  is  located  at  15245  Shady  Grove  Road,  Suite  470,  Rockville,  Maryland  20850.  Our  telephone
number is (301) 208-9191.

Available Information

Our corporate website is www.regenerx.com. Our electronic filings with the U.S. Securities and Exchange Commission, or SEC, including our
annual report on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, and any amendments to these reports filed or furnished
pursuant  to  Section  13(a)  or  15(d)  of  the  Securities  Exchange  Act  of  1934,  as  amended,  are  available  free  of  charge  through  our  website  as  soon  as
reasonably practicable after we have electronically filed such information with, or furnished such information to, the SEC.

Item 1A. Risk Factors

Set forth below and elsewhere in this report and in other documents we file with the SEC are risks and uncertainties that could cause actual results
to differ materially from the results contemplated by the forward-looking statements contained in this report. The descriptions below include any material
changes to and supersede the description of the risk factors affecting our business previously disclosed in “Part II, Item 1A. Risk Factors” of the Annual
Report.

Risks Related to Our Liquidity and Need for Financing

Before giving effect to any potential additional sales of our securities, we estimate that our existing capital will only be sufficient to fund our operations
into the second quarter of 2021.

Before giving effect to any potential additional sales of our securities, we estimate that our existing capital resources coupled with the proceeds
from the October 2020 note sales will only be sufficient to fund our operations into the second quarter of 2021. Even though we sold the 2020 Notes in
October  2020  for  proceeds  of  $500,000,  these  proceeds  are  only  projected  to  fund  our  operations  at  the  current  level  into  the  second  quarter  of  2021;
therefore, we will need to secure additional operating capital to continue operations substantially beyond the first quarter of 2021. We continuously monitor
our cash use as well as the clinical timelines. We will need to secure additional operating capital in early 2021 and are evaluating options including the
licensing of additional rights to commercialize our clinical products as well as raising capital through the capital markets, either of which could cause a
reduction in the trading price of our common stock. The COVID global pandemic may impact our ability to secure additional financing.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We will need substantial additional capital for the continued development of product candidates through marketing approval and for our longer-term
future operations.

We anticipate that substantial new capital resources will be required to continue our longer-term product development efforts, including any and
all follow-on trials that will result from our current clinical programs beyond those currently contemplated, and to scale up manufacturing processes for our
product candidates. However, the actual amount of funds that we will need will be determined by many factors, some of which are beyond our control.
These factors include, without limitation:

·

·

·

·

·

the scope of our, or our partners’, clinical trials, which is significantly influenced by the quality of clinical data achieved as trials are completed
and the requirements established by regulatory authorities;
the speed with which we, or our partners, complete our clinical trials, which depends on our ability to attract and enroll qualifying patients and
the quality of the work performed by our clinical investigators and contract research organizations chosen to conduct the studies or events such
as the COVID-19 pandemic;
the time required to prosecute, enforce and defend our intellectual property rights, which depends on evolving legal regimes and infringement
claims that may arise between us and third parties;
the  ability  to  manufacture  at  scales  sufficient  to  supply  commercial  quantities  of  any  of  our  product  candidates  that  receive  regulatory
approval, which may require levels of effort not currently anticipated; and
the successful commercialization of our product candidates, which will depend on our, or our partners’, ability to either create or partner with
an effective commercialization organization and which could be delayed or prevented by the emergence of equal or more effective therapies.

Emerging biotechnology companies like us may raise capital through corporate collaborations and by licensing intellectual property rights to other
biotechnology or pharmaceutical enterprises. We intend to pursue this strategy, but there can be no assurance that we will be able to enter into additional
license  agreements  with  respect  to  our  intellectual  property  or  product  development  programs  on  commercially  reasonable  terms,  if  at  all.  There  are
substantial  challenges  and  risks  that  will  make  it  difficult  to  successfully  implement  any  of  these  alternatives.  If  we  are  successful  in  raising  additional
capital through such a license or collaboration, we may have to give up valuable rights to our intellectual property. In addition, the business priorities of a
strategic partner may change over time, which creates the possibility that the interests of the strategic partner in developing our technology may diminish
and could have a potentially material negative impact on the value of our interest in the licensed intellectual property or product candidates.

Further, if we raise additional funds by selling shares of our common stock or securities convertible into our common stock the ownership interest
of  our  existing  stockholders  may  be  significantly  diluted.  If  additional  funds  are  raised  through  the  issuance  of  preferred  stock  or  debt  securities,  these
securities are likely to have rights, preferences and privileges senior to our common stock and may involve significant fees, interest expense, restrictive
covenants or the granting of security interests in our assets.

Our failure to successfully address our short-term capital needs and our long-term liquidity requirements would have a material negative impact on
our business, including the possibility of surrendering our rights to some technologies or product opportunities, delaying our clinical trials or ceasing our
operations.

We have incurred losses since inception and expect to incur significant losses in the foreseeable future and may never become profitable.

We have not commercialized any product candidates to date and incurred net operating losses every year since our inception in 1982. We believe
these losses will continue for the foreseeable future, and may increase, as we pursue our product development efforts related to Tß4. As of December 31,
2020, our accumulated deficit totaled approximately $109 million.

As we expand our research and development efforts and seek to obtain regulatory approval of our product candidates to make them commercially
viable,  we  anticipate  substantial  and  increasing  operating  losses.  Our  ability  to  generate  revenues  and  to  become  profitable  will  depend  largely  on  our
ability,  alone  or  through  the  efforts  of  third-party  licensees  and  collaborators,  to  efficiently  and  successfully  complete  the  development  of  our  product
candidates,  obtain  necessary  regulatory  approvals  for  commercialization,  scale-up  commercial  quantity  manufacturing  capabilities  either  internally  or
through third-party suppliers, and market our product candidates. There can be no assurance that we will achieve any of these objectives or that we will
ever  become  profitable  or  be  able  to  maintain  profitability.  Even  if  we  do  achieve  profitability,  we  cannot  predict  the  level  of  such  profitability.  If  we
continue  to  sustain  losses  over  an  extended  period  of  time  and  are  not  otherwise  able  to  raise  necessary  funds  to  continue  our  development  efforts  and
maintain our operations, we may be forced to cease operations.

Our common stock is quoted on the over-the-counter market, which subjects us to the SEC’s penny stock rules and may decrease the liquidity of our
common stock.

15

 
 
 
 
 
 
 
 
 
 
 
 
Our common stock is traded over-the-counter on the OTC Bulletin Board. Over-the-counter markets are generally considered to be less efficient
than, and not as broad as, a stock exchange. There may be a limited market for our stock now that it is quoted on the OTC Bulletin Board, trading in our
stock may become more difficult and our share price could decrease. Specifically, you may not be able to resell your shares of common stock at or above
the price you paid for such shares or at all.

In  addition,  our  ability  to  raise  additional  capital  may  be  impaired  because  of  the  less  liquid  nature  of  the  over-the-counter  markets.  While  we
cannot guarantee that we would be able to complete an equity financing on acceptable terms, or at all, we believe that dilution from any equity financing
while our shares are quoted on an over-the-counter market would likely be substantially greater than if we were to complete a financing while our common
stock is traded on a national securities exchange. Further, we are unable to use short-form registration statements on Form S-3 for the registration of our
securities, which could impair our ability to raise additional capital as needed.

Our  common  stock  is  also  subject  to  penny  stock  rules,  which  impose  additional  sales  practice  requirements  on  broker-dealers  who  sell  our
common  stock.  The  SEC  generally  defines  “penny  stock”  as  an  equity  security  that  has  a  market  price  of  less  than  $5.00  per  share,  subject  to  certain
exceptions. The ability of broker-dealers to sell our common stock and the ability of our stockholders to sell their shares in the secondary market will be
limited and, as a result, the market liquidity for our common stock will likely be adversely affected. We cannot assure you that trading in our securities will
not be subject to these or other regulations in the future.

Further, recently some discount and major brokerage firms have implemented new rules regarding the deposit of penny stock shares into new or
existing accounts where such stocks do not meet minimum price and volume requirements. Such rules may make it difficult or even prevent stockholders
from timely selling their shares through such brokerage firms unless the shares meet such minimum requirements.

The  report  of  our  independent  registered  public  accounting  firm  contains  explanatory  language  that  substantial  doubt  exists  about  our  ability  to
continue as a going concern.

The  report  of  our  independent  registered  public  accounting  firm  on  our  financial  statements  for  the  year  ended  December  31,  2020  contains
explanatory language that substantial doubt exists about our ability to continue as a going concern, without raising additional capital. As described in this
report,  even  though  we  sold  the  2020  Notes  in  October  2020  for  proceeds  of  $500,000,  these  proceeds  are  only  projected  to  fund  our  operations  at  the
current level into the second quarter of 2021; therefore, we will need to secure additional operating capital to continue operations substantially beyond the
first  quarter  of  2021.  Therefore,  we  are  seeking  sources  of  capital,  but  if  we  are  unable  to  obtain  sufficient  financing  to  support  and  complete  these
activities, then we would, in all likelihood, experience severe liquidity problems and may have to curtail our operations. If we curtail our operations, we
may be placed into bankruptcy or undergo liquidation, the result of which will adversely affect the value of our common shares.

Public health threats could have an adverse effect on our clinical trials and financial results.

Risks Related to Our Business and Operations

Public  health  threats  could  adversely  affect  our  ongoing  or  planned  business  operations.  In  particular,  the  novel  coronavirus  (COVID-19)  has
resulted  in  quarantines,  restrictions  on  travel  and  other  business  and  economic  disruptions.  We  cannot  presently  predict  the  scope  and  severity  of  any
potential business shutdowns or disruptions, but if we or any of the third parties with whom we engage, including the partners and other third parties with
whom  we  conduct  business,  were  to  experience  shutdowns  or  other  business  disruptions,  our  ability  to  conduct  our  business  in  the  manner  and  on  the
timelines presently planned could be materially and adversely impacted. The COVID-19 pandemic has affected patient accrual in our ARISE-3 clinical trial
and with the last patient being enrolled in October and completed patient treatment and follow-up in November 2020. As of the date of this report, while
we do not specifically foresee additional delays, it is impossible for us to predict further impact the COVID-19 global pandemic may have.

Our planned Phase 2 clinical trial of RGN-352 was placed on clinical hold by the FDA in March 2011 due to non-compliance of cGMP regulations by
a contract manufacturer and we are unsure when, if ever, we will be able to resume this trial.

In  the  second  half  of  2010,  we  implemented  the  development  plans  for  our  Phase  2  clinical  trial  to  evaluate  RGN-352  in  patients  who  have
suffered  an  acute  myocardial  infarction,  or  AMI.  We  had  planned  to  begin  enrolling  patients  near  the  end  of  the  first  quarter  of  2011.  However,  in
March 2011, we were notified by the FDA that the trial was placed on clinical hold as a result of our contract manufacturer’s alleged failure to comply with
current Good Manufacturing Practice (“cGMP”) regulations. The FDA has prohibited us from using any of the active drug or placebo manufactured by this
manufacturer in human trials, which will require us to identify a cGMP-compliant manufacturer and to have new material produced in the event that we
seek to resume this trial. We learned that the contract manufacturer has closed its manufacturing facility and has filed for bankruptcy protection. Significant
preparatory time and procedures will be required before any new suitable manufacturer would be able to manufacture RGN-352 for the AMI trial. Since we
are unable to estimate the length of time that the trial will be on clinical hold, we have elected to cease activities on this trial until the FDA clinical hold is
resolved  and  the  requisite  funding  might  be  secured.  Consequently,  there  can  be  no  assurance  that  we  will  be  able  to  timely  initiate  trial  activities  or
complete this trial, if at all. As of the date of this report, we have received no new information on that status of this trial.

16

 
 
 
 
 
 
 
 
 
 
 
 
 
All of our drug candidates are based on a single compound.

Our current primary business focus is the development of Tß4, and its analogues, derivatives and fragments, for the regeneration and accelerated
repair of damaged tissue from non-healing dermal and corneal wounds, cardiac injury, central/peripheral nervous system diseases and other conditions, as
well  as  an  improvement  in  various  functions,  such  as,  but  not  limited  to,  cardiac  and  neurological.  Unlike  many  pharmaceutical  companies  that  have  a
number of unique chemical entities in development, we are dependent on a single molecule, formulated for different routes of administration and different
clinical  indications,  for  our  potential  commercial  success.  As  a  result,  any  common  safety  or  efficacy  concerns  for  Tß4-based  products  that  cross
formulations would have a much greater impact on our business prospects than if our product pipeline were more diversified.

We may never be able to commercialize our product candidates.

Although Tß4 has shown biological activity in in vitro studies and in vivo animal models and while we observed clinical activity and efficacious
outcomes in our recent RGN-259 Phase 2a trial and earlier Phase 2 dermal trials, we cannot assure you that our product candidates will exhibit activity or
importance  in  humans  in  large-scale  trials.  Our  drug  candidates  are  still  in  research  and  development,  and  we  do  not  expect  them  to  be  commercially
available  for  the  foreseeable  future,  if  at  all.  Only  a  small  number  of  research  and  development  programs  ultimately  result  in  commercially  successful
drugs. Potential products that appear to be promising at early stages of development may not reach the market for a number of reasons. These include the
possibility that the potential products may:

·
·
·
·
·

be found ineffective or cause harmful side effects during preclinical studies or clinical trials;
fail to receive necessary regulatory approvals;
be precluded from commercialization by proprietary rights of third parties;
be difficult to manufacture on a large scale; or
be uneconomical or otherwise fail to achieve market acceptance.

If any of these potential problems occurs, we may never successfully market Tß4-based products.

We are subject to intense government regulation, and we may not receive regulatory approvals for our drug candidates.

Our product candidates will require regulatory approvals prior to sale. In particular, therapeutic agents are subject to stringent approval processes,
prior  to  commercial  marketing,  by  the  FDA  and  by  comparable  agencies  in  most  foreign  countries.  The  process  of  obtaining  FDA  and  corresponding
foreign  approvals  is  costly  and  time-consuming,  and  we  cannot  assure  you  that  such  approvals  will  be  granted. Also,  the  regulations  we  are  subject  to
change frequently and such changes could cause delays in the development of our product candidates.

Three of our drug candidates are currently in the clinical development stage, and we cannot be certain that we, or our partners, will successfully
complete the clinical trials necessary to receive regulatory product approvals. The regulatory approval process is lengthy, unpredictable and expensive. To
obtain regulatory approvals in the United States, we or a partner must ultimately demonstrate to the satisfaction of the FDA that our product candidates are
sufficiently safe and effective for their proposed administration to humans. Many factors, known and unknown, can adversely impact clinical trials and the
ability to evaluate a product candidate’s safety and efficacy, including:

·

·

·
·
·

the  FDA  or  other  health  regulatory  authorities,  or  institutional  review  boards,  or  IRBs,  do  not  approve  a  clinical  trial  protocol  or  place  a
clinical trial on hold;
suitable  patients  do  not  enroll  in  a  clinical  trial  in  sufficient  numbers  or  at  the  expected  rate,  for  reasons  such  as  the  size  of  the  patient
population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the perceptions of investigators and patients regarding
safety, and the availability of other treatment options;
clinical trial data is adversely affected by trial conduct or patient withdrawal prior to completion of the trial;
there may be competition with ongoing clinical trials and scheduling conflicts with participating clinicians;
patients experience serious adverse events, including adverse side effects of our drug candidates, for a variety of reasons that may or may not
be related to our product candidates, including the advanced stage of their disease and other medical problems;

17

 
 
 
 
 
 
 
 
 
 
 
 
·
·

·

patients in the placebo or untreated control group exhibit greater than expected improvements or fewer than expected adverse events;
third-party clinical investigators do not perform the clinical trials on the anticipated schedule or consistent with the clinical trial protocol and
good clinical practices, or other third-party organizations do not perform data collection and analysis in a timely or accurate manner;
service providers, collaborators or co-sponsors do not adequately perform their obligations in relation to the clinical trial or cause the trial to be
delayed or terminated;

· we are unable to obtain a sufficient supply of manufactured clinical trial materials;
·

regulatory inspections of manufacturing facilities, which may, among other things, require us or a co-sponsor to undertake corrective action or
suspend the clinical trials, such as the clinical hold with respect to our Phase 2 clinical trial of RGN-352;
the interim results of the clinical trial are inconclusive or negative;
the  clinical  trial,  although  approved  and  completed,  generates  data  that  is  not  considered  by  the  FDA  or  others  to  be  clinically  relevant  or
sufficient to demonstrate safety and efficacy; and
changes in governmental regulations or administrative actions affect the conduct of the clinical trial or the interpretation of its results.

·
·

·

There can be no assurance that clinical trials sponsored by our partners will in fact demonstrate, to the satisfaction of the FDA and others, that our
product candidates are sufficiently safe or effective. The FDA or we may also restrict or suspend our clinical trials at any time if it is believed that subjects
participating in the trials are being exposed to unacceptable health risks.

Clinical trials for product candidates such as ours are often conducted with patients who have more advanced forms of a particular condition or
other unrelated conditions. For example, in clinical trials for our product candidate RGN-137, we have studied patients who are not only suffering from
chronic epidermal wounds but who are also older and much more likely to have other serious adverse conditions. During the course of treatment with our
product candidates, patients could die or suffer other adverse events for reasons that may or may not be related to the drug candidate being tested. Further,
and as a consequence that all of our drug candidates are based on Tß4, crossover risk exists such that a patient in one trial may be adversely impacted by
one drug candidate, and that adverse event may have implications for our other trials and other drug candidates. However, even if unrelated to our product
candidates, such adverse events can nevertheless negatively impact our clinical trials, and our business prospects would suffer.

These factors, many of which may be outside of our control, may have a negative impact on our business by making it difficult to advance product
candidates or by reducing or eliminating their potential or perceived value. As a consequence, we may need to perform more or larger clinical trials than
planned. Further, if we are forced to contribute greater financial and clinical resources to a study, valuable resources will be diverted from other areas of our
business. If we fail to complete or if we experience material delays in completing our clinical trials as currently planned, or we otherwise fail to commence
or complete, or experience delays in, any of our other present or planned clinical trials, including as a result of the actions of third parties upon which we
rely for these functions, our ability to conduct our business as currently planned could materially suffer.

We may not successfully establish and maintain development and testing relationships with third-party service providers and collaborators, which could
adversely affect our ability to develop our product candidates.

We have only limited resources, experience with and capacity to conduct requisite testing and clinical trials of our drug candidates. As a result, we
rely  and  expect  to  continue  to  rely  on  third-party  service  providers  and  collaborators,  including  corporate  partners,  licensors  and  contract  research
organizations, or CROs, to perform a number of activities relating to the development of our drug candidates, including the design and conduct of clinical
trials, and potentially the obtaining of regulatory approvals. For example, we currently rely on several third-party contractors to manufacture and formulate
Tß4  into  the  product  candidates  used  in  our  clinical  trials,  develop  assays  to  assess  Tß4’s  effectiveness  in  complex  biological  systems,  recruit  clinical
investigators and sites to participate in our trials, manage the clinical trial process and collect, evaluate and report clinical results.

We may not be able to maintain or expand our current arrangements with these third parties or maintain such relationships on favorable terms. Our
agreements with these third parties may also contain provisions that restrict our ability to develop and test our product candidates or that give third parties
rights  to  control  aspects  of  our  product  development  and  clinical  programs.  In  addition,  conflicts  may  arise  with  our  collaborators,  such  as  conflicts
concerning  the  interpretation  of  clinical  data,  the  achievement  of  milestones,  the  interpretation  of  financial  provisions  or  the  ownership  of  intellectual
property developed during the collaboration. If any conflicts arise with our existing or future collaborators, they may act in their self-interest, which may be
adverse to our best interests. Any failure to maintain our collaborative agreements and any conflicts with our collaborators could delay or prevent us from
developing our product candidates. We and our collaborators may fail to develop products covered by our present and future collaborations if, among other
things:

18

 
 
 
 
 
 
 
 
 
· we or our partners do not achieve our objectives under our collaboration agreements;
· we or our partners are unable to obtain patent protection for the products or proprietary technologies we develop in our partnerships;
· we are unable to manage multiple simultaneous product development partnerships;
·
· we or our partners encounter regulatory hurdles that prevent commercialization of our product candidates; or
· we develop products and processes or enter into additional partnerships that conflict with the business objectives of our other partners.

our partners become competitors of ours or enter into agreements with our competitors;

We also have less control over the timing and other aspects of our clinical trials than if we conducted the monitoring and supervision entirely on
our own. Third parties may not perform their responsibilities for our clinical trials on our anticipated schedule or consistent with a clinical trial protocol or
applicable regulations. We, and our partners, also rely on clinical research organizations to perform much of our data management and analysis. They may
not provide these services as required or in a timely manner. If any of these parties do not meet deadlines or follow proper procedures, including procedures
required  by  law,  the  preclinical  studies  and  clinical  trials  may  take  longer  than  expected,  may  be  delayed  or  may  be  terminated,  which  would  have  a
materially negative impact on our product development efforts. If we were forced to find a replacement entity to perform any of our preclinical studies or
clinical trials, we may not be able to find a suitable entity on favorable terms or at all. Even if we were able to find a replacement, resulting delays in the
tests or trials may result in significant additional expenditures and delays in obtaining regulatory approval for drug candidates, which could have a material
adverse impact on our results of operations and business prospects.

GtreeBNT Co., Ltd. has limited drug development experience.

We  are  a  party  to  several  license  agreements  and  a  Joint  Venture  with  GtreeBNT.  Historically,  GtreeBNT’s  business  focus  has  been  in  the  IT
software industry in Korea with strong IP positions addressing specific software tools and apps such as optimized multimedia software for smart phones.
GtreeBNT  made  a  strategic  decision  in  November  2013  to  expand  into  the  biopharmaceutical  business  through  selected  strategic  alliances  with
biopharmaceutical companies in the U.S. and EU. The collaboration with RegeneRx is the first strategic investment in this initiative. While GtreeBNT has
hired executives and staff with significant pharmaceutical experience, the company has no internal drug development experience. As a result, GtreeBNT
may face more and different challenges in the development of these product candidates than would more established pharmaceutical companies.

GtreeBNT Co., Ltd. may have different public reporting requirements than RegeneRx and communications between the two companies may sometimes
conflict or be less than clear.

GtreeBNT is a public company traded on the Korean stock market. Certain disclosure requirements may differ from RegeneRx’s. Moreover, due
to  different  language  conventions,  translations  may  be  less  than  100%  accurate.  Further,  RegeneRx  may  not  always  get  material  information  related  to
clinical trials or manufacturing development or strategic product development strategy in a timely or clear manner.

GtreeBNT Co., Ltd. has limited financial resources.

GtreeBNT  has  informed  us  that  they  have  limited  financial  resources.  They  have  to  continuously  raise  capital  to  fund  research,  development,
clinical trials, and operations. Therefore, their ability to finance each of these areas is subject to its ability to secured adequate capital. While GtreeBNT has
been able to finance each of these areas, to date, there is no assurance that they will be able to do so in the future. If GtreeBNT is unable to secure necessary
financing  to  fund  clinical  trials  or  operations,  it  could  have  a  material  adverse  impact  on  RGN-137  and  RGN-259  and  our  ability  to  continue  funding
operations while these products are under development.

We  are  subject  to  intense  competition  from  companies  with  greater  resources  and  more  mature  products,  which  may  result  in  our  competitors
developing or commercializing products before or more successfully than we do.

We are engaged in a business that is highly competitive. Research and development activities for the development of drugs to treat indications
within our focus are being sponsored or conducted by private and public research institutions and by major pharmaceutical companies located in the United
States and a number of foreign countries. Most of these companies and institutions have financial and human resources that are substantially greater than
our own and they have extensive experience in conducting research and development activities and clinical trials and in obtaining the regulatory approvals
necessary  to  market  pharmaceutical  products  that  we  do  not  have.  As  a  result,  they  may  develop  competing  products  more  rapidly  that  are  safer,  more
effective,  or  have  fewer  side  effects,  or  are  less  expensive,  or  they  may  develop  and  commercialize  products  that  render  our  product  candidates  non-
competitive or obsolete.

With respect to our product candidate RGN-259, there are also numerous ophthalmic companies developing drugs for corneal wound healing and
other  front-of-the-eye  diseases  and  injuries,  including  dry  eye  syndrome.  Amniotic  membranes  have  been  successfully  used  to  treat  corneal  wounds  in
certain cases, as have topical steroids and antibacterial agents. Most specialty ophthalmic companies have a number of products on the market that could
compete with RGN-259. There are numerous antibiotics to treat eye infections to promote corneal wound healing and many eye lubrication products that
are  soothing  to  the  eye  and  help  eye  healing,  many  of  which  are  sold  without  prescriptions.  Companies  also  market  steroids  to  treat  certain  conditions
within our area of interest. Allergan, Inc. markets Restasis™, Ophthalmic Emulsion, which was the only commercially available and FDA-approved eye
drop to treat dry eye. Shire PLC recently received FDA approval to market Xiidra™ for the treatment of dry eye and has launched the product in the U.S.
Restasis. In October 2020, the FDA approved loteprednol etabonate ophthalmic suspension (Eysuvis; Kala Pharmaceuticals) a 0.25% ocular corticosteroid
indicated for dry eye disease, and other products, have been approved for marketing in certain other countries where we have licensed RGN-259.

We have initially targeted our product candidate RGN-352 for cardiovascular indications. We have also been exploring the potential of RGN-352
for the treatment of COVID-19. Most large pharmaceutical companies and many smaller biomedical companies are vigorously pursuing the development
of  therapeutics  to  treat  patients  after  heart  attacks  and  for  other  cardiovascular  indications.  Numerous  biotechnology  and  pharmaceutical  companies  are
developing products to treat COVID-19.

With respect to our product candidate RGN-137 for wound healing, Johnson & Johnson has previously marketed Regranex™ for this purpose in
patients with diabetic foot ulcers. Other companies, such as Novartis, are developing and marketing artificial skins, which we believe could also compete
with RGN-137. Moreover, wound healing is a large and highly fragmented marketplace attracting many companies, large and small, to develop products
for treating acute and chronic wounds.

We  are  also  interested  in  developing  potential  cosmeceutical  products,  which  are  loosely  defined  as  products  that  bridge  the  gap  between
cosmetics and pharmaceuticals, for example, by improving skin texture and reducing the appearance of aging. This industry is intensely competitive, with
potential  competitors  ranging  from  large  multinational  companies  to  very  small  specialty  companies.  New  cosmeceutical  products  often  have  a  short
product life and are frequently replaced with newer products developed to address the latest trends in appearance and fashion. We may not be able to adapt
to changes in the industry as quickly as larger and more experienced cosmeceutical companies. Further, larger cosmetics companies have the financial and
marketing resources to effectively compete with smaller companies like us in order to sell products aimed at larger markets.

Even if approved for marketing, our technologies and product candidates are unproven, and they may fail to gain market acceptance.

Our product candidates, all of which are based on the molecule Tß4, are new and unproven and there is no guarantee that health care providers or
patients will be interested in our product candidates, even if they are approved for use. If any of our product candidates are approved by the FDA, our
success  will  depend  in  part  on  our  ability  to  demonstrate  sufficient  clinical  benefits,  reliability,  safety,  and  cost  effectiveness  of  our,  or  our  partners’,
product  candidates  relative  to  other  approaches,  as  well  as  on  our  ability  to  continue  to  develop  our  product  candidates  to  respond  to  competitive  and
technological changes. If the market does not accept our product candidates, when and if we are able to commercialize them, then we may never become
profitable. Factors that could delay, inhibit or prevent market acceptance of our product candidates may include:

·
·
·
·
·

the timing and receipt of marketing approvals;
the safety and efficacy of the products;
the emergence of equivalent or superior products;
the cost-effectiveness of the products; and
ineffective marketing.

It is difficult to predict the future growth of our business, if any, and the size of the market for our product candidates because the markets are
continually evolving. There can be no assurance that our product candidates will prove superior to products that may currently be available or may become
available in the future or that our research and development activities will result in any commercially profitable products.

We have no marketing experience, sales force or distribution capabilities. If our product candidates are approved, and we are unable to recruit key
personnel to perform these functions, we may not be able to commercialize them successfully.

Although we do not currently have any marketable products, our ability to produce revenues ultimately depends on our, or our partners’, ability to
sell our product candidates if and when they are approved by the FDA and other regulatory authorities. We currently have no experience in marketing or
selling pharmaceutical products, and we do not have a marketing and sales staff or distribution capabilities. Developing a marketing and sales force is also
time-consuming and could delay the launch of new products or expansion of existing product sales. In addition, we will compete with many companies that
currently have extensive and well-funded marketing and sales operations. If we fail to establish successful marketing and sales capabilities or fail to enter
into successful marketing arrangements with third parties, our ability to generate revenues will suffer.

If we enter markets outside the United States our business will be subject to political, economic, legal and social risks in those markets, which could
adversely affect our business.

There are significant regulatory and legal barriers to entering markets outside the United States that must be overcome if we, or our partners, seek
regulatory approval to market our product candidates in countries other than the United States. We would be subject to the burden of complying with a
wide variety of national and local laws, including multiple and possibly overlapping and conflicting laws. We also may experience difficulties adapting to
new cultures, business customs and legal systems. Any sales and operations outside the United States would be subject to political, economic and social
uncertainties including, among others:

·
·
·
·
·
·
·

changes and limits in import and export controls;
increases in custom duties and tariffs;
changes in currency exchange rates;
economic and political instability;
changes in government regulations and laws;
absence in some jurisdictions of effective laws to protect our intellectual property rights; and
currency transfer and other restrictions and regulations that may limit our ability to sell certain product candidates or repatriate profits to the
United States.

Any changes related to these and other factors could adversely affect our business if and to the extent we enter markets outside the United States.
Additionally, we have entered into license agreements with Lee’s Pharmaceutical Limited and GtreeBNT Co, Ltd. for the development of certain of our
product  candidates  in  international  markets.  As  a  result,  these  development  activities  will  be  subject  to  compliance  in  all  respects  with  local  laws  and
regulations and may be subject to many of the risks described above.

Governmental and third-party payors may subject any product candidates we develop to sales and pharmaceutical pricing controls that could limit our
product revenues and delay profitability.

The  successful  commercialization  of  our  product  candidates,  if  they  are  approved  by  the  FDA,  will  likely  depend  on  our  ability  to  obtain
reimbursement  for  the  cost  of  the  product  and  treatment.  Government  authorities,  private  health  insurers  and  other  organizations,  such  as  health
maintenance organizations, are increasingly seeking to lower the prices charged for medical products and services. Also, the trend toward managed health
care  in  the  United  States,  the  growth  of  healthcare  maintenance  organizations,  and  recently  enacted  legislation  reforming  healthcare  and  proposals  to
reform government insurance programs could have a significant influence on the purchase of healthcare services and products, resulting in lower prices and
reducing  demand  for  our  product  candidates.  The  cost  containment  measures  that  healthcare  providers  are  instituting,  and  any  healthcare  reform  could
reduce our ability to sell our product candidates and may have a material adverse effect on our operations. We cannot assure you that reimbursement in the
United States or foreign countries will be available for any of our product candidates, and that any reimbursement granted will be maintained, or that limits
on reimbursement available from third-party payors will not reduce the demand for, or the price of, our product candidates. The lack or inadequacy of third-
party reimbursements for our product candidates would decrease the potential profitability of our operations. We cannot forecast what additional legislation
or regulation relating to the healthcare industry or third-party coverage and reimbursement may be enacted in the future, or what effect the legislation or
regulation would have on our business.

We have no manufacturing or formulation capabilities and are dependent upon third-party suppliers to provide us with our product candidates. If these
suppliers do not manufacture our product candidates in sufficient quantities, at acceptable quality levels and at acceptable cost, or if we are unable to
identify suitable replacement suppliers if needed, our clinical development efforts could be delayed, prevented or impaired.

We do not own or operate manufacturing facilities and have little experience in manufacturing pharmaceutical products. We currently rely, and
expect  to  continue  to  rely,  primarily  on  peptide  manufacturers  to  supply  us  with  Tß4  for  further  formulation  into  our  product  candidates.  We  have
historically engaged three separate smaller drug formulation contractors for the formulation of clinical grade product candidates, one for each of our three
product candidates in clinical development, although, as described in this report, the contractor we engaged to formulate and vial RGN-352 has filed for
bankruptcy and closed its manufacturing facility, and our clinical trial involving RGN-352 has been placed on clinical hold. We currently do not have an
alternative source of supply for either Tß4 or the individual drug candidates. If these suppliers, together or individually, are not able to supply us with either
Tß4 or individual product candidates on a timely basis, in sufficient quantities, at acceptable levels of quality and at a competitive price, or if we are unable
to  identify  a  replacement  manufacturer  to  perform  these  functions  on  acceptable  terms  as  needed,  our  development  programs  could  be  seriously
jeopardized.

The clinical hold on our RGN-352 trial will require us to have new material manufactured by a cGMP-compliant manufacturer in the event that
we seek to resume this trial. Significant preparatory time and procedures will be required before any new manufacturer would be able to manufacture RGN-
352  for  the  AMI  trial,  due  to  the  time  required  for  revalidation  of  processes  and  assays  related  to  such  production  that  were  already  in  place  with  the
original manufacturer. Since we are unable to estimate the length of time that the trial will be on clinical hold, we have elected to cease activities on this
trial until the FDA clinical hold is resolved and the requisite funding might be secured.

21

 
 
 
 
 
 
 
 
 
 
 
Other risks of relying solely on single suppliers for each of our product candidates include:

·

·

·
·
·

·

·

·

the possibility that our other manufacturers, and any new manufacturer that we, or our partners, may identify for RGN-352, may not be able to
ensure quality and compliance with regulations relating to the manufacture of pharmaceuticals;
their  manufacturing  capacity  may  not  be  sufficient  or  available  to  produce  the  required  quantities  of  our  product  candidates  based  on  our
planned clinical development schedule, if at all;
they may not have access to the capital necessary to expand their manufacturing facilities in response to our needs;
commissioning replacement suppliers would be difficult and time-consuming;
individual suppliers may have used substantial proprietary know-how relating to the manufacture of our product candidates and, in the event
we must find a replacement or supplemental supplier, our ability to transfer this know-how to the new supplier could be an expensive and/or
time-consuming process;
an  individual  supplier  may  experience  events,  such  as  a  fire  or  natural  disaster,  that  force  it  to  stop  or  curtail  production  for  an  extended
period;
an individual supplier could encounter significant increases in labor, capital or other costs that would make it difficult for them to produce our
products cost-effectively; or
an individual supplier may not be able to obtain the raw materials or validated drug containers in sufficient quantities, at acceptable costs or in
sufficient time to complete the manufacture, formulation and delivery of our product candidates.

Our suppliers may use hazardous and biological materials in their businesses. Any claims relating to improper handling, storage or disposal of these
materials could be time-consuming and costly to us, and we are not insured against such claims.

Our  product  candidates  and  processes  involve  the  controlled  storage,  use  and  disposal  by  our  suppliers  of  certain  hazardous  and  biological
materials  and  waste  products.  We  and  our  suppliers  and  other  collaborators  are  subject  to  federal,  state  and  local  regulations  governing  the  use,
manufacture, storage, handling and disposal of materials and waste products. Even if we and these suppliers and collaborators comply with the standards
prescribed by law and regulation, the risk of accidental contamination or injury from hazardous materials cannot be completely eliminated. In the event of
an accident, we could be held liable for any damages that result, and we do not carry insurance for this type of claim. We may also incur significant costs to
comply with current or future environmental laws and regulations.

We face the risk of product liability claims, which could adversely affect our business and financial condition.

We, or our partners, may be subject to product liability claims as a result of our testing, manufacturing, and marketing of drugs. In addition, the
use of our product candidates, when and if developed and sold, will expose us to the risk of product liability claims. Product liability may result from harm
to  patients  using  our  product  candidates,  such  as  a  complication  that  was  either  not  communicated  as  a  potential  side  effect  or  was  more  extreme  than
anticipated.  We  require  all  patients  enrolled  in  our  clinical  trials  to  sign  consents,  which  explain  various  risks  involved  with  participating  in  the  trial.
However, patient consents provide only a limited level of protection, and it may be alleged that the consent did not address or did not adequately address a
risk  that  the  patient  suffered.  Additionally,  we  will  generally  be  required  to  indemnify  our  clinical  product  manufacturers,  clinical  trial  centers,  medical
professionals and other parties conducting related activities in connection with losses they may incur through their involvement in the clinical trials.

Our ability to reduce our liability exposure for human clinical trials and commercial sales, if any, of Tß4 is dependent in part on our ability to
obtain sufficient product liability insurance or to collaborate with third parties that have adequate insurance. Although we intend to obtain and maintain
product liability insurance coverage if we gain approval to market any of our product candidates, we cannot guarantee that product liability insurance will
continue to be available to us on acceptable terms, or at all, or that its coverage will be sufficient to cover all claims against us. A product liability claim,
even  one  without  merit  or  for  which  we  have  substantial  coverage,  could  result  in  significant  legal  defense  costs,  thereby  potentially  exposing  us  to
expenses significantly in excess of our revenues, as well as harm to our reputation and distraction of our management.

If any of our key employees discontinue their services with us, our efforts to develop our business may be delayed.

We  are  highly  dependent  on  the  principal  members  of  our  management  team.  The  loss  of  our  chairman  and  Chief  Scientific  Officer,  Allan
Goldstein,  or  chief  executive  officer,  J.J.  Finkelstein  could  prevent  or  significantly  delay  the  achievement  of  our  goals.  We  cannot  assure  you  that
Dr. Goldstein or Mr. Finkelstein, or any other key employees or consultants, will not elect to terminate their employment or consulting arrangements. In
addition, we do not maintain a key man life insurance policy with respect to any of our management personnel. In the future, we anticipate that we will also
need to add additional management and other personnel. Competition for qualified personnel in our industry is intense, and our success will depend in part
on our ability to attract and retain highly skilled personnel. We cannot assure you that our efforts to attract or retain such personnel will be successful.

Mauro Bove, a member of our Board is a consultant to Lee’s Pharmaceuticals, a relationship which could give rise to a conflict of interest for

Mr. Bove.

Mauro Bove is a member of our Board of Directors and currently provides consulting services to Lee’s Pharmaceuticals Group in Hong Kong. There
can be no assurance that we will ever receive any further payments from Lee’s under the current agreement established between RegeneRx and Lee’s. As a
result of Mr. Bove’s relationship with Lee’s, Mr. Bove may have interests that are different from our other stockholders in connection with our agreement
with Lee’s and circumstances may arise that require the exercise of the Board’s discretion with respect to Lee’s that require the exclusion of Mr. Bove.

Risks Related To Our Intellectual Property

We  may  not  be  able  to  maintain  broad  patent  protection  for  our  product  candidates,  which  could  limit  the  commercial  potential  of  our  product
candidates.

Our success will depend in part on our, or our partners’, ability to obtain, defend and enforce patents, both in the United States and abroad. We
have attempted to create a substantial intellectual property portfolio, submitting patent applications for various compositions of matter, methods of use and
fragments  and  derivatives  of  Tß4.  As  described  elsewhere  in  this  report,  we  currently  do  not  have  adequate  financial  resources  to  fund  our  ongoing
business activities beyond the third quarter of 2020 without additional funding. Thus, we continuously evaluate our issued patents and patent applications
and may decide to limit their therapeutic and/or geographic coverage in an effort to enhance our ability to focus on certain medical conditions and countries
within our financial constraints. As a result, we may not be able to protect our intellectual property rights in indications and/or territories that we otherwise
would, and, therefore, our ability to commercialize Tß4, if at all, could be substantially limited, which could have a material adverse impact on our future
results of operations.

Our patents may expire before any of our product candidates reach commercialization.

Our  success  will  depend  in  part  on  our,  or  our  partners’,  patents  to  provide  market  exclusivity  for  our  product  candidates.  We  have  numerous
patent and patent applications in the U.S. and abroad. However, some of our patents are reaching the end of their 20-year patent exclusivity and, therefore,
may expire prior to developing any marketable products or expire shortly after product launch, which could negatively affect our commercial success.

If we, or our partners, are not able to maintain adequate patent protection for our product candidates, we may be unable to prevent our competitors
from using our technology or technology that we license.

Our  success  will  depend  in  substantial  part  on  our,  or  our  partners’,  abilities  to  obtain,  defend  and  enforce  patents,  maintain  trade  secrets  and
operate without infringing upon the proprietary rights of others, both in the United States and abroad. While patents covering our use of Tß4 have been
issued in some countries, we cannot guarantee whether or when corresponding patents will be issued, or the scope of any patents that may be issued, in
other countries. We have attempted to create a substantial intellectual property portfolio, submitting patent applications for various compositions of matter,
methods of use and fragments and derivatives of Tß4. We have also in-licensed other intellectual property rights from third parties that could be subject to
the same risks as our own patents. If any of these patent applications do not issue, or are not issued in certain countries, or are not enforceable, the ability to
commercialize Tß4 in various medical indications could be substantially limited or eliminated.

In addition, the patent positions of the products being developed by us and our collaborators involve complex legal and factual uncertainties. As a
result, we cannot assure you that any patent applications filed by us, or by others under which we have rights, will result in patents being issued in the
United States or foreign countries. In addition, there can be no assurance that any patents will be issued from any pending or future patent applications of
ours or our partners, that the scope of any patent protection will be sufficient to provide us with competitive advantages, that any patents obtained by us or
our partners will be held valid if subsequently challenged or that others will not claim rights in or ownership of the patents and other proprietary rights we
or  our  partners  may  hold.  Unauthorized  parties  may  try  to  copy  aspects  of  our  product  candidates  and  technologies  or  obtain  and  use  information  we
consider proprietary. Policing the unauthorized use of our proprietary rights is difficult. We cannot guarantee that no harm or threat will be made to our or
our  partners’  intellectual  property.  In  addition,  changes  in,  or  different  interpretations  of,  patent  laws  in  the  United  States  and  other  countries  may  also
adversely affect the scope of our patent protection and our competitive situation.

Due to the significant time lag between the filing of patent applications and the publication of such patents, we cannot be certain that our licensors
were the first to file the patent applications we license or, even if they were the first to file, also were the first to invent, particularly with regards to patent
rights in the United States. In addition, a number of pharmaceutical and biotechnology companies and research and academic institutions have developed
technologies,  filed  patent  applications  or  received  patents  on  various  technologies  that  may  be  related  to  our  product  candidates.  Some  of  these
technologies,  applications  or  patents  may  conflict  with  our  or  our  licensors’  technologies  or  patent  applications.  A  conflict  could  limit  the  scope  of  the
patents,  if  any,  that  we  or  our  licensors  may  be  able  to  obtain  or  result  in  denial  of  our  or  our  licensors’  patent  applications.  If  patents  that  cover  our
activities are issued to other companies, we may not be able to develop or obtain alternative technology.

Additionally,  there  is  certain  subject  matter  that  is  patentable  in  the  United  States  but  not  generally  patentable  outside  of  the  United  States.
Differences  in  what  constitutes  patentable  subject  matter  in  various  countries  may  limit  the  protection  we  can  obtain  outside  of  the  United  States.  For
example,  methods  of  treating  humans  are  not  patentable  in  many  countries  outside  of  the  United  States.  These  and  other  issues  may  prevent  us  from
obtaining  patent  protection  outside  of  the  United  States,  which  would  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of
operations.

Changes to U.S. patent laws could materially reduce any value our patent portfolio may have.

The value of our patents depends in part on their duration. A shorter period of patent protection could lessen the value of our rights under any
patents that may be obtained and may decrease revenues derived from its patents. For example, the U.S. patent laws were previously amended to change
the term of patent protection from 17 years following patent issuance to 20 years from the earliest effective filing date of the application. Because the time
from filing to issuance of biotechnology applications may be more than three years depending on the subject matter, a 20-year patent term from the filing
date may result in substantially shorter patent protection. Moreover, a divisional patent that is filed after a parent patent, if granted, would begin its term
beginning when the parent patent was initially filed, thus having an impact on the divisional patent’s practical patent life, Future changes to patent laws
could shorten our period of patent exclusivity and may decrease the revenues that we might derive from the patents and the value of our patent portfolio.

We,  or  our  partners,  may  not  have  adequate  protection  for  our  unpatented  proprietary  information,  which  could  adversely  affect  our  competitive
position.

In  addition  to  our  patents,  we,  and  our  partners,  also  rely  on  trade  secrets,  know-how,  continuing  technological  innovations  and  licensing
opportunities  to  develop  and  maintain  our  competitive  position.  However,  others  may  independently  develop  substantially  equivalent  proprietary
information  and  techniques  or  otherwise  gain  access  to  our  trade  secrets  or  disclose  our  technology.  To  protect  our  trade  secrets,  we  may  enter  into
confidentiality  agreements  with  employees,  consultants  and  potential  collaborators.  However,  we  may  not  have  such  agreements  in  place  with  all  such
parties and, where we do, these agreements may not provide meaningful protection of our trade secrets or adequate remedies in the event of unauthorized
use or disclosure of such information. Also, our trade secrets or know-how may become known through other means or be independently discovered by our
competitors. Any of these events could prevent us from developing or commercializing our product candidates.

We may be subject to claims that we or our employees have wrongfully used or disclosed alleged trade secrets of former employers.

As is commonplace in the biotechnology industry, we employ now, and may hire in the future, individuals who were previously employed at other
biotechnology or pharmaceutical companies, including competitors or potential competitors. Although there are no claims currently pending against us, we
may be subject to claims that we or certain employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of
former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could
result in substantial costs and would be a significant distraction to management.

Risks Related To Our Securities

Our common stock price is volatile, our stock is highly illiquid, and any investment in our securities could decline substantially in value.

For  the  period  from  January  1,  2020  through  March  1,  2021  the  closing  price  of  our  common  stock  has  ranged  from  $0.14  to  $0.75,  with  an
average daily trading volume of approximately 96,000 shares. In light of our small size and limited resources, as well as the uncertainties and risks that can
affect our business and industry, our stock price is expected to continue to be highly volatile and can be subject to substantial drops, with or even in the
absence of news affecting our business. The following factors, in addition to the other risk factors described in this report, and the potentially low volume
of trades in our common stock since it is not listed on a national securities exchange, may have a significant impact on the market price of our common
stock, some of which are beyond our control:

·
·
·

results of pre-clinical studies and clinical trials;
commercial success of approved products;
corporate partnerships;

24

 
 
 
 
 
 
 
 
 
 
 
 
 
·
·
·
·
·
·
·
·
·

technological innovations by us or competitors;
changes in laws and government regulations both in the U.S. and overseas;
changes in key personnel at our company;
developments concerning proprietary rights, including patents and litigation matters;
public perception relating to the commercial value or safety of any of our product candidates;
other issuances of our common stock, or securities convertible into or exercisable for our common stock, causing dilution;
anticipated or unanticipated changes in our financial performance;
general trends related to the biopharmaceutical and biotechnological industries; and
general conditions in the stock market.

The stock market in general has recently experienced relatively large price and volume fluctuations. In particular, the market prices of securities of
smaller biotechnology companies have experienced dramatic fluctuations that often have been unrelated or disproportionate to the operating results of these
companies. Continued market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in its value. You
should also be aware that price volatility may be worse if the trading volume of the common stock remains limited or declines.

Our principal stockholders have significant voting power and may take actions that may not be in the best interests of our other stockholders.

Our officers, directors and principal stockholders together control approximately 48.2% of our outstanding common stock. Included in this group
are previous stockholders of Sigma-Tau and their affiliates, which now have consolidated their holding into Essetifin S.p.A. which holds outstanding shares
representing approximately 26.2% of our outstanding common stock and GtreeBNT which owns approximately 14.7% of our outstanding common stock.
These  stockholders  also  hold  options,  warrants,  convertible  promissory  notes  and  stock  purchase  rights  that  provide  them  with  the  right  to  acquire
significantly more shares of common stock. Accordingly, if these stockholders acted together, they could control the outcome of all stockholder votes. This
concentration of ownership may have the effect of delaying or preventing a change in control and might adversely affect the market price of our common
stock, and therefore may not be in the best interest of our other stockholders.

If securities or industry analysts do not publish research or reports or publish unfavorable research about our business, the price of our common stock
and other securities and their trading volume could decline.

The trading market for our common stock and other securities will depend in part on the research and reports that securities or industry analysts
publish  about  us  or  our  business.  We  currently  have  research  coverage  by  one  securities  and  industry  analyst,  and  from  time-to-time  other  independent
analysts. If securities or industry analysts do not commence or maintain coverage of us, the trading price for our common stock and other securities would
be negatively affected. In the event one or more of the analysts who covers us downgrades our securities, the price of our securities would likely decline. If
one or more of these analysts ceases to cover us or fails to publish regular reports on us, interest in the purchase of our securities could decrease, which
could cause the price of our common stock and other securities and their trading volume to decline.

The  exercise  of  options  and  warrants,  conversion  of  convertible  promissory  notes,  and  other  issuances  of  shares  of  common  stock  or  securities
convertible into common stock will dilute your interest.

As of December 31, 2020, there were outstanding options to purchase an aggregate of 11,951,250 shares of our common stock under our 2010 and
2018 incentive equity plans at exercise prices ranging from $0.16 per share to $0.64 per share and outstanding warrants to purchase 9,529,288 shares of our
common stock at a weighted average exercise price of $0.21 per share. In October 2020, we sold a series of convertible promissory notes that will initially
be  convertible  at  $0.36  into  1,391,982  shares  and  we  also  issued  warrants  to  purchase  1,043,988  shares  with  an  exercise  price  $0.45  per  share.  In
February 2019 we sold a series of convertible promissory notes that will initially be convertible at $0.12 into 10,833,333 shares and also issued warrants to
purchase 8,125,000 shares with an exercise price of $0.18 per share. The exercise of options and warrants or note conversions at prices below the market
price of our common stock could adversely affect the price of shares of our common stock. Additional dilution may result from the issuance of shares of
our capital stock in connection with collaborations or manufacturing arrangements or in connection with other financing efforts.

Any issuance of our common stock that is not made solely to then-existing stockholders proportionate to their interests, such as in the case of a
stock dividend or stock split, will result in dilution to each stockholder by reducing his, her or its percentage ownership of the total outstanding shares.
Moreover, if we issue options or warrants to purchase our common stock in the future and those options or warrants are exercised or we issue restricted
stock, stockholders may experience further dilution. Holders of shares of our common stock have no preemptive rights that entitle them to purchase their
pro rata share of any offering of shares of any class or series.

25

 
 
 
 
 
 
 
 
 
 
 
Our certificate of incorporation and Delaware law contain provisions that could discourage or prevent a takeover or other change in control, even if
such a transaction would be beneficial to our stockholders, which could affect our stock price adversely and prevent attempts by our stockholders to
replace or remove our current management.

Our certificate of incorporation provides our Board with the power to issue shares of preferred stock without stockholder approval. In addition, we
are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. Subject to specified exceptions, this section provides
that  a  corporation  may  not  engage  in  any  business  combination  with  any  interested  stockholder,  as  defined  in  that  statute,  during  the  three-year  period
following the time that such stockholder becomes an interested stockholder. This provision could also have the effect of delaying or preventing a change of
control of our company. The foregoing factors could reduce the price that investors or an acquirer might be willing to pay in the future for shares of our
common stock.

We  may  become  involved  in  securities  class  action  litigation  that  could  divert  management’s  attention  and  harm  our  business  and  our  insurance
coverage may not be sufficient to cover all costs and damages.

The stock market has from time-to-time experienced significant price and volume fluctuations that have affected the market prices for the common
stock of pharmaceutical and biotechnology companies. These broad market fluctuations may cause the market price of our common stock to decline. In the
past, following periods of volatility in the market price of a particular company’s securities, securities class action litigation has often been brought against
that company. If we experience this sort of volatility, we may become involved in this type of litigation in the future. Litigation often is expensive and
diverts management’s attention and resources, which could hurt our business, operating results and financial condition.

We have never declared or paid a cash dividend on our common stock and since all of our funds are committed to clinical research, we do not

anticipate that any cash dividends will be paid on our common stock in the foreseeable future.

In October 2020, we sold the 2020 Notes. The sale of the 2020 Notes resulted in gross proceeds to the Company of $500,000. In January 2020,
Sabby  exercised  their  remaining  warrants  and  the  Company  received  proceeds  of  $241,911.  At  present,  with  the  receipt  of  the  sale  proceeds  from  the
closing on the 2020 Notes in October 2020, we have sufficient cash to fund planned operations into the second quarter of 2021.

In February 27, 2019 we sold a series of convertible promissory notes to accredited investors including Essetifin S.p.A., our largest stockholder
(the “2019 Notes”). The sale of in the 2019 Notes resulted in gross proceeds to the Company of $1,300,000 over two closings. The first closing in the
amount of $650,000 occurred in February 2019 and the second closing, also in the amount of $650,000, occurred on May 13, 2019, after the Company
provided notice of the enrollment of the first patent in the ARISE-3 clinical trial in patients with dry eye syndrome (“DES”) sponsored by ReGenTree. The
2019 Notes contain a $0.12 conversion price and are initially convertible into 10,833,333 shares of common stock. The purchasers also received a warrant
exercisable at $0.18 to purchase additional 8,125,000 shares of common stock.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operation.

You  should  read  the  following  discussion  and  analysis  together  with  our  financial  statements  and  the  related  notes  included  elsewhere  in  this

annual report.

Business Overview

We are a biopharmaceutical company focused on the development of a novel therapeutic peptide, Thymosin beta 4, or Tß4, for tissue and organ

protection, repair, and regeneration. We have formulated Tß4 into three distinct product candidates in clinical development:

•

•

•

RGN-259, a preservative-free topical eye drop for regeneration of corneal tissues damaged by injury, disease or other pathology;

RGN-352,  an  injectable  formulation  to  treat  cardiovascular  diseases,  central  and  peripheral  nervous  system  diseases,  and  other  medical
indications that may be treated by systemic administration; and

RGN-137, a topical gel for dermal wounds and reduction of scar tissue.

We are continuing strategic partnership discussions with biotechnology and pharmaceutical companies regarding the further clinical development

of all of our product candidates.

Current Financial Circumstances

In October 2020, we sold the 2020 Notes. The sale of the 2020 Notes resulted in gross proceeds to the Company of $500,000. In January 2020,
Sabby  exercised  their  remaining  warrants  and  the  Company  received  proceeds  of  $241,911.  At  present,  with  the  receipt  of  the  sale  proceeds  from  the
closing on the 2020 Notes in October 2020, we have sufficient cash to fund planned operations into the second quarter of 2021.

Current Clinical Status

In  January  2015,  we  entered  into  a  Joint  Venture  Agreement  with  GtreeBNT  whereby  we  created  ReGenTree  LLC  (“ReGenTree”  or  “Joint
Venture”) jointly owned by us and GtreeBNT, which will commercialize RGN-259 for treatment of dry eye syndrome and neurotrophic keratitis, an orphan
ophthalmic indication in the United States.

To date ReGenTree has sponsored a Phase 2/3 clinical trial (“ARISE-1”) and Phase 3 clinical trials in patients with DES (“ARISE-2”). Last year it
completed  a  Phase  3  clinical  trial  in  patients  with  neurotrophic  keratitis  (“NK”)  (“SEER-1”),  and  is  currently  sponsoring  a  Phase  3  trial  (ARISE-3)  in
patients with DES, both in the U.S. In May 2016, we reported the results of the 317-patient ARISE-1 trial and in October 2017, we reported the results of
the  ARISE-2  trial.  The  ARISE-2  study,  which  was  sponsored  by  ReGenTree  and  managed  by  Ora,  Inc.  pursuant  a  contract  between  the  parties,
demonstrated a number of statistically significant improvements in both signs and symptoms of DES with 0.1% RGN-259 versus placebo, while showing
excellent  safety,  comfort,  and  tolerability  profiles.  The  ocular  discomfort  symptom  showed  a  statistically  significant  reduction  in  the  RGN-259-treated
group  at  day  15  as  compared  to  placebo  (p=0.0149)  in  the  change  from  baseline.  For  sign,  RGN-259  also  improved  the  dry  eye  patient’s  ability  to
withstand  an  exacerbated  condition  in  a  patient  subgroup  with  both  compromised  corneal  fluorescein  staining  and  Schirmer’s  test  at  baseline.  In  this
population, RGN-259 showed superiority over placebo in reducing corneal fluorescein staining in the change from baseline at days 15 and 29 (p=0.0207
and 0.0254, respectively). RGN-259 confirmed its global effects on dry eye syndrome and fast onset in multiple sign and symptom efficacies with no safety
issues  in  the  ARISE-1  and  ARISE-2  studies  as  well  as  in  the  pooled  data,  although  ARISE-2  was  not  successful  in  duplicating  the  results  of  ARISE-1
where the study population was limited and less diversified. ReGenTree is proceeding with its RGN-259 development plan as discussed with the FDA in
April 2018. ReGenTree and Ora, Inc. have entered into a contract for management of ARISE-3. The first patient was enrolled in the second quarter of 2019
and the last patient was enrolled in October 2020. Due to the COVID-19 pandemic, the completion of ARISE-3 was delayed from the original timeline but
the patent treatment and follow-up was completed in November as ReGenTree previously reported in clinicaltrials.gov. As of the date of this filing, the
patient database has been locked and topline results are expected shortly.

The NK trial (SEER-1), a smaller study in an orphan population, enrolled of 18 patients. On May 14, 2020, the Company reported that the trial
was closed and reported the results of SEER-1. Six out of 10 patients in the RGN-259 treated group and 1 out of 8 patients in the placebo treated group
achieved  complete  corneal  healing  in  four  weeks.  In  terms  of  the  primary  endpoint,  “ratio  of  corneal  wound  healed  patients  after  four  weeks'
administration”, the statistical difference was slightly over 0.05 (p = 0.0656, Fisher's exact test), due to the limited number of patients in each group. When
another  statistical  analysis  method  was  used  to  analyze  the  same  primary  endpoint  (Chi  square  test),  there  was  statistical  significance,  p  =  0.0400.  In
addition, in a pre-specified secondary endpoint evaluating corneal epithelial healing at day 43 (two weeks post-treatment) and the durability of RGN-259
treatment, we also confirmed a clear statistical difference using the Fisher's exact test, p = 0.0359. Several other efficacy parameters were either highly
significant or strongly trending toward statistical significance in the RGN-259 group indicating the depth of patient response to RGN-259.

GtreeBNT has developed the CMC (chemistry, manufacturing and controls) dossier required for Phase 3 clinical trials and commercialization in
the  U.S.  and  in  Korea.  This  comprehensive  and  critical  effort  ensures  that  final  drug  product  manufacturing,  packaging,  stability,  purity,
reproducibility, etc., meets regulatory guidelines and product specifications. The product of this activity is the current product formulation being utilized in
the U.S. trials being conducted by ReGenTree and will also be utilized in the planned clinical activity to be conducted by GtreeBNT under the RGN-259
license agreement for Pan Asia.

During the past several years, ReGenTree, LLC began developing a modified eye drop formulation that it believes will enhance the efficacy of
thymosin  beta  4  for  NK,  improve  the  patient  experience,  and  allow  a  proprietary  valued  orphan  product  price  for  this  rare  disease.  The  Company  has
completed a preliminary formulation for NK patients that will be considered for use in future clinical study. ReGenTree has not yet determined if it will use
this new formulation in the future for NK.

In February 2017, our licensee for RGN-137, GtreeBNT, through its subsidiary, Lenus Therapeutics, LLC, received permission from the FDA to
sponsor a Phase 3 clinical trial using RGN-137 to treat patients with epidermolysis bullosa (“EB”), a genetic disease that causes severe blistering of the
skin and internal organs. In August 2017, the Company amended the agreement for RGN-137 held by GtreeBNT. Under the amendment the Territory was
expanded to include Europe, Canada, South Korea, Australia and Japan. In December 2018, GtreeBNT initiated a small Phase 2 open trial in patients with
EB to evaluate RGN-137 in such patients prior to sponsoring a larger Phase 3 trial. Three patients have been enrolled in the open clinical trial to date. It
was reported in August 2019, that the first patient had positively responded to RGN-137. As of the date of this report, the Company has not been updated
as to current enrollment status.

Financial Operations Overview

We  have  never  generated  product  revenues,  and  we  do  not  expect  to  generate  product  revenues  until  the  FDA  approves  one  of  our  product
candidates, if ever, and we begin marketing and selling it. We anticipate incurring additional operating losses in the future as we continue to explore the
potential clinical benefits of Tß4-based product candidates over multiple indications. To fund further development and clinical trials we have entered into a
series of strategic partnerships under licensing and joint venture agreements (see Note 4 of our financial statements) where our partners are responsible for
advancing development of our product candidates with multiple clinical trials.

In October 2020, we sold the 2020 Notes. The sale of the 2020 Notes resulted in gross proceeds to the Company of $500,000. In January 2020,
Sabby  exercised  their  remaining  warrants  and  the  Company  received  proceeds  of  $241,911.  At  present,  with  the  receipt  of  the  sale  proceeds  from  the
closing  on  the  2020  Notes  in  October  2020,  we  have  sufficient  cash  to  fund  planned  operations  into  the  second  quarter  of  2021.  Accordingly,  we  will
continue to evaluate opportunities to raise additional capital and are in the process of exploring various alternatives, including, without limitation, a public
or private placement of our securities, debt financing, corporate collaboration and licensing arrangements, government grants, or the sale of our company or
certain of our intellectual property rights.

Most of our expenditures to date have been for research and development, or R&D, activities and general and administrative, or G&A, activities.
R&D costs include all of the wholly-allocable costs associated with our various clinical programs passed through to us by our outsourced vendors. Those
costs include manufacturing Tß4 and peptide fragments, formulation of Tß4 into our product candidates, stability studies for both Tß4, and the various
formulations,  preclinical  toxicology,  safety  and  pharmacokinetic  studies,  clinical  trial  management,  medical  oversight,  laboratory  evaluations,  statistical
data analysis, regulatory compliance, quality assurance and other related activities. R&D includes cash and non-cash compensation, payroll taxes, travel
and other miscellaneous costs of our internal R&D personnel, three persons in total, who are dedicated on a part-time hourly basis to R&D efforts. R&D
also includes a proration of our common infrastructure costs for office space and communications. We expense our R&D costs as they are incurred.

R&D expenditures are subject to the risks and uncertainties associated with clinical trials and the FDA review and approval process. As a result,
these expenses could exceed our expectations, possibly materially. We are uncertain as to what we will incur in future research and development costs for
our clinical studies, as these amounts are subject to, management's continuing assessment of the economics of each individual research and development
project and the internal competition for project funding.

28

 
 
 
 
 
 
 
 
 
 
 
G&A costs include outside professional fees for legal, business development, audit and accounting services. G&A also includes cash and non-cash
compensation,  travel  and  other  miscellaneous  costs  of  our  internal  G&A  personnel,  two  in  total,  who  are  wholly  dedicated  to  G&A  efforts.  G&A  also
includes  a  proration  of  our  common  infrastructure  costs  for  office  space  and  communications.  Our  G&A  expenses  also  include  costs  to  maintain  our
intellectual property portfolio. Historically we have expanded our patent prosecution activities, and in some cases, we have filed patent applications for
non-critical strategic purposes intended to prevent others from filing similar patent claims. We continue to closely monitor our patent applications in the
United States, Europe and other countries with the advice of outside legal counsel to determine if they will continue to provide strategic benefits. In cases
where we believe the benefit has been realized or it becomes unnecessary due to the issuance of other patents, or for other reasons that will not affect the
strength of our intellectual property portfolio, we have and will continue to abandon these patent applications in order to reduce our costs of continued
prosecution or maintenance.

Critical Accounting Policies

We prepare our financial statements in conformity with accounting principles generally accepted in the United States of America. Such accounting
principles require that our management make estimates and assumptions that affect the amounts reported in our financial statements and accompanying
notes.  Our  actual  results  could  differ  materially  from  those  estimates.  The  items  in  our  financial  statements  that  have  required  us  to  make  significant
estimates and judgments are as follows:

Revenue Recognition

The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with
customers, (ii) identification of distinct performance obligations in the contract, (iii) determination of contract transaction price, (iv) allocation of contract
transaction price to the performance obligations and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation.
The  Company  recognizes  revenues  upon  the  satisfaction  of  its  performance  obligation  (upon  transfer  of  control  of  promised  goods  or  services  to  our
customers)  in  an  amount  that  reflects  the  consideration  to  which  it  expects  to  be  entitled  to  in  exchange  for  those  goods  or  services.  Whenever  we
determine  that  an  arrangement  should  be  accounted  for  as  a  single  unit  of  accounting,  we  must  determine  the  period  over  which  the  performance
obligations will be performed, and revenue will be recognized. Revenue will be recognized using either a relative performance or straight-line method. We
recognize revenue using the relative performance method provided that we can reasonably estimate the level of effort required to complete our performance
obligations under an arrangement and such performance obligations are provided on a best-efforts basis. Revenue recognized is limited to the lesser of the
cumulative amount of payments received or the cumulative amount of revenue earned, as determined using the relative performance method, as of each
reporting period.

The  Company’s  contracts  with  customers  may  at  times  include  multiple  promises  to  transfer  products  and  services.  Contracts  with  multiple
promises are analyzed to determine whether the promises, which may include a license together with performance obligations such as providing a clinical
supply of product and steering committee services, are distinct and should be accounted for as separate performance obligations or whether they must be
accounted  for  as  a  single  performance  obligation.  The  Company  accounts  for  individual  performance  obligations  separately  if  they  are  distinct.
Determining  whether  products  and  services  are  considered  distinct  performance  obligations  may  require  significant  judgment.  If  we  cannot  reasonably
estimate  when  our  performance  obligation  either  ceases  or  becomes  inconsequential  and  perfunctory,  then  revenue  is  deferred  until  we  can  reasonably
estimate  when  the  performance  obligation  ceases  or  becomes  inconsequential.  Revenue  is  then  recognized  over  the  remaining  estimated  period  of
performance.

Whenever the Company determines that an arrangement should be accounted for as a combined performance obligation, we must determine the
period  over  which  the  performance  obligation  will  be  performed  and  when  revenue  will  be  recognized.  Revenue  is  recognized  using  either  a  relative
performance or straight-line method. We recognize revenue using the relative performance method provided that we can reasonably estimate the level of
effort required to complete our performance obligation under an arrangement and such performance obligation is provided on a best-efforts basis. Revenue
recognized is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined using the
relative performance method, as of each reporting period.

If  the  Company  cannot  reasonably  estimate  the  level  of  effort  required  to  complete  our  performance  obligation  under  an  arrangement,  the
performance  obligation  is  provided  on  a  best-efforts  basis  and  we  can  reasonably  estimate  when  the  performance  obligation  ceases  or  the  remaining
obligations  become  inconsequential  and  perfunctory,  then  the  total  payments  under  the  arrangement,  excluding  royalties  and  payments  contingent  upon
achievement of substantive milestones, would be recognized as revenue on a straight-line basis over the period we expect to complete our performance
obligations. Revenue is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined
using the straight-line basis, as of the period ending date.

29

 
 
 
 
 
 
 
 
 
 
If the Company cannot reasonably estimate when our performance obligation either ceases or becomes inconsequential and perfunctory, revenue is
deferred  until  we  can  reasonably  estimate  when  the  performance  obligation  ceases  or  becomes  inconsequential.  Revenue  is  then  recognized  over  the
remaining estimated period of performance.

At  the  inception  of  each  arrangement  that  includes  development  milestone  payments,  the  Company  evaluates  the  probability  of  reaching  the
milestones and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue
reversal would not occur in the future, the associated milestone value is included in the transaction price. 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  and
therefore revenue recognized is constrained as management is unable to assert that a reversal of revenue would not be possible. The transaction price is
then  allocated  to  each  performance  obligation  on  a  relative  standalone  selling  price  basis,  for  which  the  Company  recognizes  revenue  as  or  when  the
performance  obligations  under  the  contract  are  satisfied.  At  the  end  of  each  subsequent  reporting  period,  the  Company  re-evaluates  the  probability  of
achievement of such development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such
adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

Amounts received prior to satisfying the above revenue recognition criteria are recorded as unearned revenue in our accompanying balance sheets.

Contract assets are generated when contractual billing schedules differ from revenue recognition timing. Contract assets represent a conditional
right to consideration for satisfied performance obligations that becomes a billed receivable when the conditions are satisfied. There were no contract assets
as of December 31, 2020.

Contract liabilities result from arrangements where we have received payment in advance of performance under the contract. Changes in contract

liabilities are generally due to either receipt of additional advance payments or our performance under the contract.

We have the following amounts recorded for contract liabilities:

The  contract  liabilities  amounts  disclosed  above  as  of  December  31,  2020  and  2019,  are  primarily  related  to  revenue  being  recognized  on  a
straight-line  basis  over  periods  ranging  from  23  to  30  years,  which,  in  management’s  judgment,  is  the  best  measure  of  progress  towards  satisfying  the
performance obligations and represents the Company’s best estimate of the period of the obligation.

Share-based payment

We account for share-based compensation based on the estimated grant date fair value of the award using the Black-Scholes option-pricing model.

The estimated grant date fair value is recognized over the requisite service period.

Determining the appropriate fair value model and calculating the fair value of share-based payment awards require the input of highly subjective
assumptions, including the expected life of the share-based payment awards and stock price volatility. Since our historical data is limited, the expected life
was determined in accordance with SEC Staff Accounting Bulletin No. 107 guidance for “plain vanilla” options. Since our historical trading volume is
relatively low, we estimated the expected volatility based on monthly closing prices for a period consistent with the expected life of the option.

The  assumptions  used  in  calculating  the  fair  value  of  share-based  payment  awards  represent  management’s  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,  our  stock-
based compensation expense could be materially different in the future. See Notes 2 and 8 to the Financial Statements for a further discussion on stock-
based compensation and the relative ranges of our historical, underlying assumptions.

Results of Operations

Comparison of years ended December 31, 2020 and 2019

Revenues. For the year ended December 31, 2020, we recorded revenue in the amount of approximately $77,000 versus $77,000 recorded for the
year ended December 31, 2019. The revenue reflects the amortization over 30 years of the payments we received under the original joint venture license
agreement and the payment we received for the expansion of the territorial rights to include Canada in April 2016. The payments received under the 2017
RGN-137 license amendment were amortized for revenue over 23 years.

Expenses — Research and development. For the year ended December 31, 2020, our R&D expenditures decreased by $60,000, or 92%, to $5,000,
from approximately $65,000 in 2019. The limited R&D expenditures reflects the shift of our internal R&D efforts as our partners assume full responsibility
for clinical development. The decrease in 2020 results from the classification of stock option compensation expense in G&A to more accurately reflect the
Company’s current operations versus 2019. We expect our R&D expenses will remain at low levels unless we decide to reinitiate internal R&D efforts for
our unpartnered programs.

Expenses — General and administrative. For the year ended December 31, 2020, our G&A expenses increased by approximately $93,000, or 7%,
to  $1,366,000  from  $1,274,000  in  2019.  Increases  are  reflected  in  2020  expenses  for  personnel  and  related  (increase  of  $39,000)  and  stock  option
compensation  expense  (increase  of  $125,000)  ,  These  increases  were  partially  offset  by  decreases  in  professional  fees  (decrease  of  $7,000),  insurance
(decrease of $13,000), sponsorship (decrease of $5,000), travel (decrease of $9,000), investor relations (decrease of $25,000), facility and related (decrease
of $4,000), license fees (decrease of $2,000) and other (decrease of $6,000). We believe that our G&A expenses will remain at current levels as we wait for
data from the upcoming clinical trials being conducted by our partners. If we enter into additional partnerships or other business transactions, including
financings, we will incur additional legal and transaction related expenses.

Interest Expense. Our statement of operations reflects interest expense of $232,631 for the year ended December 31, 2020 versus $153,410 for the
year  ended  December  31,  2019.  The  increase  reflects  the  2019  Notes  being  outstanding  for  the  full  year  as  well  as  the  issuance  of  the  2020  Notes  in
October 2020.

Net Loss. Our statement of operations reflects a net loss of $1,523,368 for the year ended December 31, 2020 versus net loss of $1,404,247 for the

year ended December 31, 2019. Losses from operations increased in 2020 versus 2019, $1,294,543 and $1,261,881, respectively.

Liquidity and Capital Resources

We  have  not  commercialized  any  of  our  product  candidates  to  date  and  have  incurred  significant  losses  since  inception.  In  addition,  we  have
primarily  financed  our  operations  through  the  equity  or  issuance  of  debt  including  the  sale  of  a  series  of  convertible  promissory  notes  through  private
placements with accredited investors and the March and August 2014 private placements of common stock with GtreeBNT as well as our entry into the
ReGenTree  joint  venture  in  early  2015.  The  report  of  our  independent  registered  public  accounting  firm  regarding  our  financial  statements  for  the  year
ended  December  31,  2020  contains  an  explanatory  paragraph  regarding  our  ability  to  continue  as  a  going  concern  based  upon  our  history  of  operating
losses and dependence on future financing in order to meet our planned operating activities.

Our  statement  of  operations  reflects  a  net  loss  of  $1,523,368  for  the  year  ended  December  31,  2020.  We  had  cash  and  cash  equivalents  of
$427,898  at  December  31,  2020.  In  October  2020,  we  sold  the  2020  Notes,  resulting  in  gross  proceeds  to  the  Company  of  $500,000.  In  January  2020,
Sabby  exercised  their  remaining  warrants  and  the  Company  received  proceeds  of  $241,911.  At  present,  with  the  receipt  of  the  sale  proceeds  from  the
closing on the 2020 Notes in October 2020, we have sufficient cash to fund planned operations into the second quarter of 2021.

We  may  also  receive  funds  from  grants,  new  partnerships  or  the  raising  of  additional  capital  if  the  market  climate  warrants.  Additionally,  we
intend to continue to pursue additional partnering activities, particularly for RGN-352, our injectable systemic product candidate for cardiac and central
nervous system indications. This estimate also does not include receipt of any funds from grants, new partnerships or the raising of additional capital if the
market climate warrants. A sale of common stock and warrants, a convertible instrument or additional partnering of licensed rights are possible sources of
operating  capital  in  the  future.  Additionally,  we  intend  to  continue  to  pursue  additional  partnering  activities,  particularly  for  RGN-352,  our  injectable
systemic product candidate for cardiac and central nervous system indications.

Net Cash Used in Operating Activities. Net cash used in operating activities was $1,007,000 and $1,138,000 for the years ended December 31,

2020 and 2019, respectively. The decrease is 2020 reflects an increase in accrued expenses on the 2020 balance sheet.

Net Cash Used in Investing Activities. We did not use any cash for investing activities in 2020 or 2019.

Net  Cash  Provided  by  Financing  Activities.  Net  cash  provided  by  financing  activities  totaled  $795,000  and  $1,541,000  for  the  years  ended
December 31, 2020 and 2019, respectively. In 2020, the cash provided by financing activities consisted of the proceeds from the sale of the 2020 Notes of
$500,000 and $242,000 from the exercise of warrants and the receipt of a Paycheck Protection Program loan, administered by the U.S. Small Business
Administration, of $55,000, while in 2019 the cash provided by financing activities consisted of the proceeds from the sale of the 2019 Notes of $1,300,000
and $241,000 from the exercise of warrants.

Future Funding Requirements

The expenditures that will be necessary to execute our business plan are subject to numerous uncertainties that may adversely affect our liquidity
and capital resources. Currently, RegeneRx has active partnerships in four major territories: the U.S., Europe, China and Pan Asia. Our partners have been
moving forward and making progress in each territory. In each case, the cost of development is being borne by our partners with no financial obligation for
RegeneRx. Patient accrual, treatment, and follow-up for ophthalmic trials are, in general, relatively fast, as opposed to most other clinical efforts, ARISE-3,
ReGenTree’s Phase 3 trial, was initiated and the first patient was enrolled in the second quarter of 2019 and enrollment was completed in November 2020.
Top line data from ARISE-3 is expected shortly.

We still have significant clinical assets to develop, primarily RGN-352 (injectable formulation of Tß4 for cardiac and CNS disorders) in the U.S.,
Pan Asia, and Europe, and RGN-259 in the EU. Our goal is to wait until the results are obtained from the current ophthalmic clinical trials before moving
into the EU with RGN-259. If successful, this should allow us to obtain a higher value for the clinical asset at that time. However, we intend to continue to
develop RGN-352, either by obtaining grants to fund a Phase 2a clinical trial in the cardiovascular or central nervous system fields or finding a suitable
partner with the resources and capabilities to develop it as we have with RGN-259.

In  addition,  the  length  of  time  required  for  clinical  trials  varies  substantially  according  to  the  type,  complexity,  novelty  and  intended  use  of  a

product candidate. Some of the factors that could impact our liquidity and capital needs include, but are not limited to:

·
·
·
·
·
·

·
·

the progress of our clinical trials;
the progress of our research activities;
the number and scope of our research programs;
the progress of our preclinical development activities;
the costs involved in preparing, filing, prosecuting, maintaining, enforcing and defending patent and other intellectual property claims;
the costs related to development and manufacture of preclinical, clinical and validation lots for regulatory purposes and commercialization of
drug supply associated with our product candidates;
our ability to enter into corporate collaborations and the terms and success of these collaborations;
the costs and timing of regulatory approvals; and

32

 
 
 
 
 
 
 
 
 
 
 
 
·

the costs of establishing manufacturing, sales and distribution capabilities.

Moreover, the duration and the cost of clinical trials may vary significantly over the life of a project as a result of differences arising during the

clinical trial protocol, including, among others, the following:

·
·
·
·

the number of patients that ultimately participate in the trial;
the duration of patient follow-up that seems appropriate in view of the results;
the number of clinical sites included in the trials; and
the length of time required to enroll suitable patient subjects.

Also, we test our product candidates in numerous preclinical studies to identify indications for which they may be efficacious. We may conduct
multiple clinical trials to cover a variety of indications for each product candidate. As we obtain results from trials, we may elect to discontinue clinical
trials for certain product candidates or for certain indications in order to focus our resources on more promising product candidates or indications.

Our proprietary product candidates have not yet achieved FDA regulatory approval, which is required before we can market them as therapeutic
products. In order to proceed to subsequent clinical trial stages and to ultimately achieve regulatory approval, the FDA must conclude that our clinical data
establish safety and efficacy. Historically, the results from preclinical studies and early clinical trials have often not been predictive of results obtained in
later  clinical  trials.  A  number  of  new  drugs  and  biologics  have  shown  promising  results  in  clinical  trials,  but  subsequently  failed  to  establish  sufficient
safety and efficacy data to obtain necessary regulatory approvals.

Sources of Liquidity

We have not commercialized any of our product candidates to date and have primarily financed our operations through the issuance of common
stock and common stock warrants in private and public financings. In June of 2016, we raised $1,520,000 by selling 5,147,059 shares of common stock and
warrants  to  purchase  5,147,059  shares  of  common  stock  to  Sabby.  On  March  2,  2018,  we  entered  into  a  warrant  reprice  and  exercise  and  issuance
agreement with Sabby, which, in consideration of the holders exercising in full all of the 2016 Offering warrants the exercise price per share of the warrants
was reduced to $0.20 per share. In addition, and as further consideration, we issued to the holders of the 2016 Offering warrants 3,860,294 new warrants
with an exercise price of $0.2301 per share. Pursuant to the terms of the Reprice Agreement the exercise price of the new warrants will be reduced from
$0.2301  to  $0.125  as  a  result  of  the  sale  of  the  2019  Notes.  We  received  gross  proceeds  of  approximately  $1,000,000  pursuant  the  exercise  and  issued
5,147,059  of  common  stock.  In  February  2019,  we  sold  a  series  of  convertible  promissory  notes  to  accredited  investors  including  Essetifin  S.p.A.,  our
largest shareholder. The sale of the notes resulted in gross proceeds to the Company of $1,300,000 over two closings. The first closing in the amount of
$650,000 occurred in February 2019 and the second closing, also in the amount of $650,000, occurred on May 13, 2019 after the Company provided notice
of the enrollment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. The notes contain a $0.12 conversion price and are
initially convertible into 10,833,333 chares off common stock. The purchasers also received a warrant exercisable at $0.18 to purchase additional 8,125,000
shares  of  common  stock.  In  addition,  we  received  proceeds  of  $115,625  pursuant  to  the  exercise  of  warrants  held  by  Sabby  Management  as  well  as
$125,000 for April 2019 warrant exercises. In January 2020, Sabby exercised their remaining warrants and the Company received proceeds of $241,911. In
October 2020, we sold the 2020 Notes resulting in gross proceeds to the Company of $500,000. The 2020 Notes were accompanied by 2020 Warrants. At
present,  with  the  receipt  of  the  sale  proceeds  from  the  closing  on  the  2020  Notes  and  proceeds  from  the  January  2020  warrant  exercises,  we  will  have
sufficient cash to fund planned operations into the second quarter of 2021.

We continuously monitor our cash use as well as the clinical timelines. We continue to evaluate options including the licensing of additional rights

to commercialize our clinical products as well as raising capital through the capital markets.

We have various strategic agreements and license agreements with: GtreeBNT, ReGenTree and Lee’s. These license agreements provide for the
opportunity for us to receive milestone payments upon specified commercial events and royalty payments in connection with any commercial sales of the
licensed products in the respective territories. However, there are no assurances that we will be able to attain any such milestones or generate any such
royalty payments under the agreements.

Licensing Agreements

As noted above, we have entered into two strategic agreements with GtreeBNT. GtreeBNT licensed the development and commercialization rights
for RGN-259, in Asia (excluding China, Hong Kong, Macau and Taiwan) while also licensing the development and commercialization rights for RGN-137
in  the  U.S.  In  August  2017,  the  Company  amended  the  license  agreement  for  RGN-137  held  by  GtreeBNT.  Under  the  amendment  the  Territory  was
expanded to include Europe, Canada, South Korea, Australia and Japan. In January 2015, we entered into a joint venture and licensing agreement with
GtreeBNT that will commercialize RGN-259 for treatment of dry eye and neurotrophic keratitis in the United States, as well as any other indications within
the field of ophthalmology. The license agreements provide for the opportunity for us to receive milestone payments upon specified commercial events and
royalty payments in connection with any commercial sales of the licensed products in the respective territories. However, there are no assurances that we
will be able to attain any such milestones or generate any such royalty payments under the agreements.

33

 
 
 
 
 
 
 
 
 
 
 
 
 
We also have entered into a license agreement with Lee’s Pharmaceuticals that provides for the opportunity for us to receive milestone payments
upon specified events and royalty payments in connection with any commercial sales of Tß4-based products in China, Hong Kong, Macau and Taiwan
(Greater  China).  However,  there  are  no  assurances  that  we  will  be  able  to  attain  any  such  milestones  or  generate  any  such  royalty  payments  under  the
agreement. In February 2019, the agreement was amended and assigned by Lee’s to their affiliate, Zhaoke Ophthalmology Pharmaceutical Limited. There
were no economic changes to the agreement.

Government Grants

We  have  pursued,  and  may  continue  to  pursue,  government  funding  for  both  RGN-259  and  RGN-352.  We  are  not  currently  receiving  funding

under a Government Grant.

Other Financing Sources

Other potential sources of outside capital include entering into additional strategic business relationships, additional issuances of equity securities
or debt financing or other similar financial instruments. If we raise additional capital through a strategic business relationship, we may have to give up
valuable rights to our intellectual property. If we raise funds by selling additional shares of our common stock or securities convertible into our common
stock, the ownership interest of our existing stockholders may be significantly diluted. In addition, if additional funds are raised through the issuance of
preferred  stock  or  debt  securities,  these  securities  are  likely  to  have  rights,  preferences  and  privileges  senior  to  our  common  stock  and  may  involve
significant fees, interest expense, restrictive covenants and the granting of security interests in our assets.

Our failure to successfully address liquidity requirements could have a materially negative impact on our business, including the possibility of
surrendering our rights to some technologies or product opportunities, delaying our clinical trials, or ceasing operations. There can be no assurance that we
will be able to obtain additional capital in sufficient amounts, on acceptable terms, or at all.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as such term is defined in Item 303(a)(4) of Regulation S-K.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Not applicable.

Item 8. Financial Statements and Supplementary Data.

The financial statements required by this item are included beginning on page F-1 of this report.

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

None.

Item 9A. Controls and Procedures.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in reports that we file
or submit under the Exchange Act is recorded, processed, summarized and timely reported as provided in SEC rules and forms and that such information is
accumulated and communicated to our management, including our Chief Executive Officer who currently serves as both our principal executive officer and
our  principal  financial  officer,  as  appropriate,  to  allow  for  timely  decisions  regarding  required  disclosure.  We  periodically  review  the  design  and
effectiveness  of  our  disclosure  controls  and  procedures,  including  compliance  with  various  laws  and  regulations  that  apply  to  our  operations.  We  make
modifications to improve the design and effectiveness of our disclosure controls and procedures and may take other corrective action if our reviews identify
a  need  for  such  modifications  or  actions.  In  designing  and  evaluating  the  disclosure  controls  and  procedures,  we  recognize  that  any  controls  and
procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and we apply
judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in
part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals
under  all  potential  future  conditions;  over  time,  controls  may  become  inadequate  because  of  changes  in  conditions,  or  the  degree  of  compliance  with
policies or procedures may deteriorate. Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be
detected.

34

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We have carried out an evaluation, under the supervision and the participation of our management, including our Chief Executive Officer, of the
effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act),
as of December 31, 2020 the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer, in his capacity as principal
executive officer and principal financial officer, concluded that our disclosure controls and procedures were effective as of December 31, 2020.

Management’s Annual Report on Internal Control over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting,  as  such  term  is  defined  in
Exchange Act Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting
principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that,
in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the  company;  (ii)  provide  reasonable  assurance  that
transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that
receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and
(iii)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or  disposition  of  the  company’s  assets  that
could have a material effect on our financial statements.

Because of its inherent limitations, including the possibility of human error and the circumvention or overriding of controls, a system of internal
control  over  financial  reporting  can  provide  only  reasonable  assurance  and  may  not  prevent  or  detect  all  misstatements. Therefore,  even  those  systems
determined  to  be  effective  can  provide  only  reasonable  assurance  with  respect  to  financial  statement  preparation  and  presentation.  Further,  because  of
changes in conditions, effectiveness of internal control over financial reporting may vary over time.

A  significant  deficiency  is  a  control  deficiency,  or  combination  of  control  deficiencies,  in  internal  control  over  financial  reporting  that  is  less
severe than a material weakness, yet important enough to merit attention by those responsible for oversight of the company’s financial reporting. A material
weakness is a deficiency, or combination of control deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a
material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Under the supervision and with the participation of our management, including our Chief Executive Officer in his capacity as principal executive
officer  and  principal  financial  officer,  we  conducted  an  evaluation  of  the  effectiveness  of  our  internal  control  over  financial  reporting  based  on  the
framework  set  forth  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.
Based on our evaluation, management has concluded that our internal control over financial reporting was effective as of December 31, 2020.

This  Annual  Report  does  not  include  an  attestation  report  of  the  Company’s  independent  registered  public  accounting  firm  regarding  internal
control  over  financial  reporting.  Management’s  report  was  not  subject  to  attestation  by  the  Company’s  independent  registered  public  accounting  firm
pursuant to the rules of the Securities and Exchange Commission that permit the Company to provide only management’s report in this Annual Report.

Changes in Internal Control over Financial Reporting

There were no changes to the Company’s Internal Controls over Financial Reporting in the year ended December 31, 2020.

Executive Officers and Directors

PART III

The following table sets forth as of March 1, 2020, the name, age and position of each person who serves as an executive officer or director of our
company. There are no family relationships among any of our executive officers or directors, with the exception that Mr. Finkelstein is the first cousin of
Dr. Goldstein’s wife.

We seek to assemble a board that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and

1998 as Director of Scientific Office and Strategic Alliances within the Corporate R&D organization. In this position he managed key R&D projects and

of  our  company.  Officers,  directors  and  greater  than  ten  percent  stockholders  are  required  by  SEC  regulation  to  furnish  us  with  copies  of  all
Section 16(a) forms they file.

To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations of our directors and officers
that  no  other  reports  were  required,  during  the  fiscal  year  ended  December  31,  2020,  all  Section  16(a)  filing  requirements  applicable  to  our  officers,

Corporate Code of Conduct and Ethics

We have adopted a corporate code of conduct and ethics that applies to all of our employees, officers and directors, as well as a separate code of

ethics  for  our  principal  executive  and  financial  officers  are  available  on  our  corporate  website  at  www.regenerx.com.  If  we  make  any  substantive
amendments to the corporate code of conduct and ethics or the code of ethics for our principal executive and financial officers or grant any waivers from a
provision of these codes to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website.

Audit Committee and Audit Committee Financial Expert

We have a separately designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. The members

of the audit committee are Messrs. McNay and Elsey. Mr. McNay serves as chairman of the audit committee.

Our board of directors periodically reviews the independence of our audit committee members and has determined that all current members of our
audit committee are independent under NYSE Amex listing standards. Although our common stock is no longer listed on the NYSE Amex exchange, we
have determined the independence of our audit committee members using the NYSE Amex definitions of independence.

Our board of directors has also determined that each of Mr. McNay and Mr. Elsey qualifies as an audit committee financial expert, as defined in

applicable SEC rules.

Employment Agreements; Potential Payments Upon Termination or Change in Control

Employment Agreement with Mr. Finkelstein

We entered into an employment agreement with Mr. Finkelstein on April 16, 2014 for him to serve as our president and chief executive officer.
Mr. Finkelstein’s employment agreement has an initial three-year term, which is automatically renewed for additional one-year periods unless either we or
Mr.  Finkelstein  elect  not  to  renew  it.  Mr.  Finkelstein’s  annual  base  salary  was  $125,000,  which  was  increased  to  $150,000  on  January  1,  2015  and
subsequently reduced back to $125,000 in March 2018. Mr. Finkelstein’s salary may not be adjusted downward without his written consent, except in a
circumstance  which  is  part  of  a  general  reduction  or  other  concessionary  arrangement  affecting  all  employees  or  affecting  senior  executive  officers.
Effective January 1, 2019, Mr. Finkelstein suggested and consented that his salary be reduced to $80,000 annually, a level at which it remained in 2020.
Mr. Finkelstein is also eligible to receive an annual bonus in an amount established by the Board and is entitled to participate in and receive all standard
employee benefits and to participate in all of our applicable incentive plans, including stock option, stock, bonus, savings and retirement plans. We also
provide him with $1 million in life insurance.

Mr. Finkelstein is eligible to receive options to purchase common stock under our equity incentive plans. The decision to grant any such options
and the terms of such options are within the discretion of our Board or the compensation committee thereof. All vested options are exercisable for a period
of time following any termination of Mr. Finkelstein’s employment as may be set forth in the applicable benefit plan or in any option agreement between
Mr. Finkelstein and us.

In the event that Mr. Finkelstein’s employment is terminated by us without “cause” or by Mr. Finkelstein for “good reason,” each as defined in his
employment agreement, subject to Mr. Finkelstein’s entering into and not revoking a release of claims in a form acceptable to us, Mr. Finkelstein will be
entitled  to  receive  (i)  a  lump  sum  payment  in  an  amount  equal  to  one-half  of  his  then  annual  base  salary  if  within  the  first  anniversary  date  of  this
Agreement; or (ii) a lump sum payment in an amount equal to three-fourths of his then annual base salary if within the first anniversary date and second
anniversary date of this Agreement; or (iii) a lump sum payment in an amount equal to his then annual base salary if any time after the second anniversary
date  of  this  Agreement,  less  all  federal  and  state  withholdings.  In  the  event  of  a  “change  in  control,”  as  defined  in  his  employment  agreement  and
Mr. Finkelstein is involuntarily terminated within 12 months after a change in control event or within 12 months after a change in control event he resigns
his employment for “good reason”, then the Company shall (i) pay Mr. Finkelstein, in a lump sum cash payment, an amount equal to his annual base salary
in  effect  on  the  date  of  his  termination  from  employment,  less  any  applicable  federal  and  state  taxes  and  withholdings.  In  addition,  in  each  instance
Mr. Finkelstein would also be eligible to receive (i) any earned bonus and accrued vacation pay, and (ii) to the extent that he is eligible for and participates
in a Company sponsored health insurance plan the Company shall pay or reimburse Executive for the amount of any insurance premiums for a twelve-
month period, but these payments shall be limited to the amount of the premiums being paid by the Company for Executive’s coverage or the amount being
reimbursed for insurance premiums immediately prior to the date of his termination from employment.

In addition, if Mr. Finkelstein’s employment is terminated without “cause,” or if there is a “change in control” event, in each case as defined in
either the applicable benefit plan or in Mr. Finkelstein’s employment agreement, then the unvested portion of Mr. Finkelstein’s outstanding options would
accelerate in full.

2020 Convertible Notes

In October 2020, we sold the 2020 Notes to management, the Company’s Board of Directors and accredited investors including Essetifin S.p.A.,
our largest stockholder. The 2020 Notes bear interest at a rate of five percent (5%) per annum and are convertible into shares of our common stock at a
conversion price of twelve cents ($0.36) per share (subject to adjustment as described in the 2020 Notes) at any time prior to repayment, at the election of
the investors. In the aggregate, the 2020 Notes issued in both closings are convertible into up to 1,391,382 shares of our common stock excluding interest.

At any time prior to maturity of the 2020 Notes, with the consent of the holders of a majority in interest of the 2020 Notes, we can prepay the
outstanding principal amount of the 2020 Notes plus unpaid accrued interest without penalty. The outstanding principal and all accrued interest on the 2020
Notes will accelerate and automatically become immediately due and payable upon the occurrence of certain events of default.

In connection with the issuance of the 2020 Notes we also issued the 2020 Warrants to each investor. The 2020 Warrants are exercisable for an

aggregate of 1,043,988 shares of common stock with an exercise price of forty-five cents ($0.45) per share for a period of five years.

2019 Convertible Notes

In February 2019, we sold the 2019 Notes to management, the Company’s Board of Directors and accredited investors including Essetifin S.p.A.,
our largest stockholder.”). The sale of the 2019 Notes resulted in gross proceeds to the Company of $1,300,000 over two closings. The first closing in the
amount of $650,000 occurred in February 2019 and the second closing, also in the amount of $650,000, occurred on May 13, 2019 after the Company
provided notice of the enrollment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. The 2019 Notes will mature on March 1,
2024. The 2019 Notes bear interest at a rate of five percent (5%) per annum and are convertible into shares of our common stock at a conversion price of
twelve cents ($0.12) per share (subject to adjustment as described in the 2019 Notes) at any time prior to repayment, at the election of the investors. In the

Scientific Advisor and Chairman of our Board of Directors.

GtreeBNT

In August 2017, the Company and GtreeBNT reached an agreement to expand the territorial definition of the RGN-137 license agreement in Japan
in  exchange  for  a  series  of  payments,  two  of  which  were  received  in  2017  with  the  remaining  two  were  received  in  2018.  Under  the  amendment  the
Territory was expanded to include Europe, Canada, South Korea, Australia and Japan.

U.S. Joint Venture

On  January  28,  2015,  we  announced  that  we  had  entered  into  a  Joint  Venture  Agreement  with  GtreeBNT  a  shareholder  of  the  Company.
ReGenTree,  LLC  was  created  under  the  Agreement  and  is  jointly  owned  by  us  and  GtreeBNT.  ReGenTree  intends  to  commercialize  RGN-259  for
treatment  of  dry  eye  and  neurotrophic  keratitis,  an  orphan  indication  in  the  United  States.  GtreeBNT  will  be  responsible  for  funding  all  product
development  and  commercialization  efforts  and  holds  a  majority  interest  in  ReGenTree  that  varies  depending  on  development  milestones  achieved  and
eventual  commercialization  path,  if  successful.  In  conjunction  with  the  Joint  Venture  Agreement,  we  also  entered  into  a  royalty-bearing  license  with
ReGenTree pursuant to which we granted to ReGenTree the right to develop and exclusively commercialize RGN-259 in the United States. We received a
total of $1 million in two tranches under the terms of the agreement. The first tranche of $500,000 was received in March 2015 and a second in the amount
of  $500,000,  was  received  in  September  2015.  On  April  6,  2016,  we  received  $250,000  from  ReGenTree  and  executed  an  amendment  to  the  license
agreement on April 28, 2016. Under the amendment, the territorial rights were expanded to include Canada.

Our initial ownership interest in ReGenTree was 49% and has been reduced to 38.5% after filing of the final clinical study report with the FDA for
the Phase 3 trial for Dry Eye Syndrome completed in 2017. Based on when, and if, ReGenTree achieves certain additional development milestones in the
U.S. with RGN-259, our equity ownership may be incrementally reduced to between 38.5% and 25%, with 25% being the final equity ownership upon
FDA  approval  of  an  BLA  for  Dry  Eye  Syndrome  in  the  U.S.  In  addition  to  our  equity  ownership,  RegeneRx  retains  a  royalty  on  net  sales  that  varies
between single and low double digits, depending on whether commercial sales are made by ReGenTree or a licensee. In the event ReGenTree is acquired,
or a change of control occurs following achievement of an BLA, RegeneRx shall be entitled to a minimum of 40% of all proceeds paid or payable and will
forgo any future royalties.

In September 2015, ReGenTree began a Phase 2/3 clinical trial in patients with dry eye syndrome (“DES”) and a Phase 3 clinical trial in patients
with neurotrophic keratitis (“NK”), both in the U.S. In May 2016, we reported the results of the 317-patient Phase 2/3 trial (ARISE-1). The FDA approved
ReGenTree’s Phase 3 protocol for DES in late summer 2016 and we initiated a second Phase 3 trial (ARISE-2) that was completed in approximately 600
patients, the results of which were reported in October 2017. ReGenTree initiated a third Phase 3 trial (ARISE-3), and the first patient was enrolled in the
second quarter of 2019 and enrollment is expected to be completed in the summer of 2020.

The NK trial (SEER-1), a smaller study in an orphan population, has enrolled seventeen patients. ReGenTree had previously disclosed that 7 of the
17  patients  enrolled  in  SEER-1  had  completely  healed.  To  participate  in  the  trial  the  patients  were  required  to  have  a  persistent  epithelial  defect  (non-
healing corneal wound). While these preliminary observations are encouraging, it should be noted that the patients and treating physicians remain masked
while the trial is on-going, so it is not known whether the healed patients are in the RGN-259 group, placebo group, or distributed among both. We expect
ReGenTree will report top line data in the next few months.

Director Independence

Under  NYSE Amex  listing  standards,  a  majority  of  the  members  of  a  listed  company’s  board  of  directors  must  qualify  as  “independent,”  as
affirmatively  determined  by  the  board.  Although  our  common  stock  is  no  longer  listed  on  the  NYSE  Amex  exchange,  we  have  determined  the
independence of our directors using the NYSE Amex definitions of independence. Our board consults with counsel to ensure that its determinations are
consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing
standards of the NYSE Amex, as in effect from time to time.

44

 
 
 
 
 
 
 
 
 
 
 
 
Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his family
members,  and  our  company,  our  senior  management  and  our  independent  auditors,  our  board  has  determined  that  the  following  three  directors  are
independent  directors  within  the  meaning  of  the  applicable  NYSE  Amex  listing  standards:  Mr.  Elsey,  Mr.  Bove  and  Mr.  McNay.  In  making  this
determination, the board found that none of these directors had a material or other disqualifying relationship with us. Mr. Finkelstein, our President and
Chief Executive Officer, and Dr. Goldstein our Chief Scientific Officer, are not independent by virtue of their employment with us.

In determining the independence of Mr. Bove, the board of directors considered the significant ownership of our common stock by Essetifin S.p.A.
and our license agreement with Lee’s Pharmaceuticals. The board of directors does not believe that any of the transactions with Lee’s or Essetifin and its
affiliates described in this report has interfered or would reasonably be expected to interfere with Mr. Bove’s exercise of independent judgment in carrying
out his responsibilities as a director of our company.

Our  audit  committee  has  adopted  a  policy  and  procedures  for  the  pre-approval  of  audit  and  non-audit  services  rendered  by  our  independent
registered public accounting firm. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services,
and tax services up to specified amounts. Pre-approval may also be given as part of the audit committee’s approval of the scope of the engagement of the
independent registered public accounting firm or on an individual explicit case-by-case basis before the independent registered public accounting firm is
engaged  to  provide  each  service.  On  a  periodic  basis,  the  independent  registered  public  accounting  firm  reports  to  the  audit  committee  on  the  status  of
actual costs for approved services against the approved amounts.

The  audit  committee  has  determined  that  the  rendering  of  the  services  other  than  audit  services  by  CohnReznick  LLP  is  compatible  with

maintaining that firm’s independence.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
RegeneRx Biopharmaceuticals, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of RegeneRx Biopharmaceuticals, Inc. (the “Company”) as of December 31, 2020 and 2019, and the
related statements of operations, changes in stockholders’ deficit and cash flows for the years then ended and the related notes (collectively referred to as
the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the
Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for the years then ended in conformity with accounting
principles generally accepted in the United States of America.

The Company's Ability to Continue as a Going Concern

The  financial  statements  have  been  prepared  assuming  that  the  Company  will  continue  as  a  going  concern.  As  discussed  in  Note  1  to  the  financial
statements, the Company has incurred losses from operations since inception and will need additional capital to fund future operations. These conditions
raise  substantial  doubt  about  the  Company's  ability  to  continue  as  a  going  concern.  The  financial  statements  do  not  include  any  adjustments  that  might
result from the outcome of this uncertainty.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of
internal  control  over  financial  reporting,  but  not  for  the  purposes  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over
financial reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding amounts and disclosures in the
financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit 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.

/s/ CohnReznick LLP

We have served as the Company’s auditor since 2012.

1.

ORGANIZATION AND BUSINESS

Organization and Nature of Operations.

RegeneRx Biopharmaceuticals, Inc. (“RegeneRx”, the “Company”, “We”, “Us”, “Our”), a Delaware corporation, was incorporated in 1982. We
are  focused  on  the  discovery  and  development  of  novel  molecules  to  accelerate  tissue  and  organ  repair.  Our  operations  are  confined  to  one  business
segment: the development and marketing of product candidates based on Thymosin Beta 4 (“Tß4”), an amino acid peptide.

Management Plans to Address Operating Conditions.

Our  strategy  is  aimed  at  being  capital  efficient  while  leveraging  our  portfolio  of  clinical  assets  by  seeking  strategic  relationships  with
organizations with clinical development capabilities including development capital. Currently, we have active partnerships in four major territories: North
America, Europe, China and Pan Asia. In each case, the cost of development is being borne by our partners with no financial obligation for RegeneRx. We
still have significant clinical assets to develop, primarily RGN-352 (injectable formulation of Tß4 for cardiac and CNS disorders) in the U.S., Pan Asia, and
Europe, and RGN-259 in the EU. Our goal is to wait until satisfactory results are obtained from the current ophthalmic clinical program in the U.S. before
moving  into  the  EU.  However,  we  intend  to  continue  to  develop  RGN-352,  our  injectable  systemic  product  candidate  for  cardiac  and  central  nervous
system indications, either by obtaining grants to fund a Phase 2a clinical trial in the cardiovascular or central nervous system fields or finding a suitable
partner with the resources and capabilities to develop it as we have with RGN-259.

Since  inception,  and  through  December  31,  2020,  we  have  an  accumulated  deficit  of  $109  million  and  we  had  cash  and  cash  equivalents  of
$427,898 as of December 31, 2020. We anticipate incurring additional operating losses in the future as we continue to explore the potential clinical benefits
of  Tß4-based  product  candidates  over  multiple  indications.  We  have  entered  into  a  series  of  strategic  partnerships  under  licensing  and  joint  venture
agreements where our partners are responsible for advancing development of our product candidates by sponsoring multiple clinical trials. In October 2020,
we sold a series of convertible promissory notes to management, the Company’s Board of Directors and accredited investors including Essetifin S.p.A., our
largest stockholder (the “2020 Notes”). The sale of the 2020 Notes resulted in gross proceeds to the Company of $500,000. The 2020 Notes contain a $0.36
conversion  price  and  the  purchasers  also  received  a  warrant  exercisable  at  $0.45  to  purchase  additional  shares  of  common  stock  equal  to  75%  of  the
number of shares into which each note is initially convertible (the “2020 Warrants”). In February 2019, we sold a series of convertible promissory notes to
management, the Company’s Board of Directors and accredited investors including Essetifin S.p.A., our largest stockholder (the “2019 Notes”). The sale of
the  2019  Notes  resulted  in  gross  proceeds  to  the  Company  of  $1,300,000  over  two  closings.  The  first  closing  in  the  amount  of  $650,000  occurred  in
February 2019 and the second closing, also in the amount of $650,000, occurred on May 13, 2019 after the Company provided notice of the enrollment of
the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. The 2019 Notes contain a $0.12 conversion price and the purchasers also
received  a  warrant  exercisable  at  $0.18  to  purchase  additional  shares  of  common  stock  equal  to  75%  of  the  number  of  shares  into  which  each  note  is
initially convertible (the “2019 Warrants”). In addition, we received proceeds of $115,625 pursuant to the exercise of warrants held by Sabby Management
as well as $125,000 for April 2019 warrant exercises. In January 2020, Sabby exercised their remaining warrants and the Company received proceeds of
$241,911. At present, with the receipt of the proceeds the 2020 Notes, we will have sufficient cash to fund planned operations into the second quarter of
2021.

While  we  successfully  secured  additional  operating  capital  to  continue  operations  into  the  second  quarter  of  2021,  we  will  need  substantial
additional funds in order to significantly advance development of our unlicensed programs. Accordingly, we will continue to evaluate opportunities to raise
additional capital and are in the process of exploring various alternatives, including, without limitation, a public or private placement of our securities, debt
financing, corporate collaboration and licensing arrangements, or the sale of our Company or certain of our intellectual property rights.

These factors raise substantial doubt about our ability to continue as a going concern. The accompanying financial statements have been prepared
assuming that we will continue as a going concern. This basis of accounting contemplates the recovery of our assets and the satisfaction of our liabilities in
the normal course of business.

Although  we  intend  to  continue  to  seek  additional  financing  or  additional  strategic  partners,  we  may  not  be  able  to  complete  a  financing  or
corporate transaction, either on favorable terms or at all. If we are unable to complete a financing or strategic transaction, we may not be able to continue as
a going concern after our funds have been exhausted, and we could be required to significantly curtail or cease operations, file for bankruptcy or liquidate
and dissolve. There can be no assurance that we will be able to obtain any sources of funding. The financial statements do not include any adjustments
relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should we be forced to
take any such actions.

F-7

 
 
 
 
 
 
 
 
 
 
 
 
In  addition  to  our  current  operational  requirements,  we  continually  refine  our  operating  strategy  and  evaluate  alternative  clinical  uses  of  Tß4.
However, substantial additional resources will be needed before we will be able to achieve sustained profitability. Consequently, we continually evaluate
alternative sources of financing such as the sharing of development costs through strategic collaboration agreements. There can be no assurance that our
financing efforts will be successful and, if we are not able to obtain sufficient levels of financing, we would delay certain clinical and/or research activities
and  our  financial  condition  would  be  materially  and  adversely  affected.  Even  if  we  are  able  to  obtain  sufficient  funding,  other  factors  including
competition,  dependence  on  third  parties,  uncertainty  regarding  patents,  protection  of  proprietary  rights,  manufacturing  of  peptides,  and  technology
obsolescence could have a significant impact on us and our operations.

To achieve profitability, we, and/or a partner, must successfully conduct pre-clinical studies and clinical trials, obtain required regulatory approvals
and successfully manufacture and market those pharmaceuticals we wish to commercialize. The time required to reach profitability is highly uncertain, and
there can be no assurance that we will be able to achieve sustained profitability, if at all.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use  of  Estimates.  The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of
America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported earnings, financial position and various
disclosures. Critical accounting policies involved in applying our accounting policies are those that require management to make assumptions about matters
that are highly uncertain at the time the accounting estimate was made and those for which different estimates reasonably could have been used for the
current period. Critical accounting estimates are also those which are reasonably likely to change from period to period and would have a material impact
on  the  presentation  of  our  financial  condition,  changes  in  financial  condition  or  results  of  operations.  Our  most  critical  accounting  estimates  relate  to
accounting policies for revenue recognition, discount rate used to calculate the present value of the future lease payments and share-based arrangements.
Management bases its estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances. Actual
results could differ from these estimates.

Cash and Cash Equivalents. Cash and cash equivalents consist of cash and highly liquid investments with original maturities of three months or

less when acquired and are stated at cost that approximates their fair market value.

Concentration of Credit Risk. Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of
cash and cash equivalents. We limit our exposure to credit loss by placing our cash and cash equivalents with high quality financial institutions and, in
accordance with our investment policy, in securities that are rated investment grade.

Property and Equipment. Property and equipment consist of office furniture and equipment and is stated at cost and depreciated over the estimated
useful lives of the assets (generally two to five years) using the straight-line method. Expenditures for maintenance and repairs which do not significantly
prolong  the  useful  lives  of  the  assets  are  charged  to  expense  as  incurred.  All  property  and  equipment  is  fully  depreciated  at  December  31,  2020.
Depreciation expense was $0 and $1,418 for the years ended December 31, 2020 and 2019, respectively.

Impairment  of  Long-lived  Assets.  When  we  record  long-lived  assets,  our  policy  is  to  regularly  perform  reviews  to  determine  if  and  when  the

carrying value of our long-lived assets becomes impaired. During the years ended December 31, 2020 and 2019, no impairment losses were recorded.

Convertible  Notes  with  Detachable  Warrants.  In  accordance  with  the  Financial  Accounting  Standards  Board  (“FASB”)  Accounting  Standards
Codification (“ASC”) 470-20, Debt  with  Conversion  and  Other  Options,  the  proceeds  received  from  convertible  notes  are  allocated  to  the  instruments
based on the relative fair values of the convertible notes without the warrants and of the warrants themselves at the time of issuance. The portion of the
proceeds allocated to the warrants is recognized as additional paid-in capital and a debt discount. The debt discount related to warrants is accreted into
interest expense through maturity of the notes.

Revenue  Recognition.  The  Company  analyzes  contracts  to  determine  the  appropriate  revenue  recognition  using  the  following  steps:
(i) identification of contracts with customers, (ii) identification of distinct performance obligations in the contract, (iii) determination of contract transaction
price,  (iv)  allocation  of  contract  transaction  price  to  the  performance  obligations  and  (v)  determination  of  revenue  recognition  based  on  timing  of
satisfaction of the performance obligation. The Company recognizes revenues upon the satisfaction of its performance obligation (upon transfer of control
of promised goods or services to our customers) in an amount that reflects the consideration to which it expects to be entitled to in exchange for those
goods or services. Whenever we determine that an arrangement should be accounted for as a single unit of accounting, we must determine the period over
which the performance obligations will be performed, and revenue will be recognized. Revenue will be recognized using either a relative performance or
straight-line method. We recognize revenue using the relative performance method provided that we can reasonably estimate the level of effort required to
complete our performance obligations under an arrangement and such performance obligations are provided on a best-efforts basis. Revenue recognized is
limited  to  the  lesser  of  the  cumulative  amount  of  payments  received  or  the  cumulative  amount  of  revenue  earned,  as  determined  using  the  relative
performance method, as of each reporting period.

F-8

 
 
 
 
 
 
 
 
 
 
 
 
 
The  Company’s  contracts  with  customers  may  at  times  include  multiple  promises  to  transfer  products  and  services.  Contracts  with  multiple
promises are analyzed to determine whether the promises, which may include a license together with performance obligations such as providing a clinical
supply of product and steering committee services, are distinct and should be accounted for as separate performance obligations or whether they must be
accounted  for  as  a  single  performance  obligation.  The  Company  accounts  for  individual  performance  obligations  separately  if  they  are  distinct.
Determining  whether  products  and  services  are  considered  distinct  performance  obligations  may  require  significant  judgment.  If  we  cannot  reasonably
estimate  when  our  performance  obligation  either  ceases  or  becomes  inconsequential  and  perfunctory,  then  revenue  is  deferred  until  we  can  reasonably
estimate  when  the  performance  obligation  ceases  or  becomes  inconsequential.  Revenue  is  then  recognized  over  the  remaining  estimated  period  of
performance.

Whenever the Company determines that an arrangement should be accounted for as a combined performance obligation, we must determine the
period  over  which  the  performance  obligation  will  be  performed  and  when  revenue  will  be  recognized.  Revenue  is  recognized  using  either  a  relative
performance or straight-line method. We recognize revenue using the relative performance method provided that we can reasonably estimate the level of
effort required to complete our performance obligation under an arrangement and such performance obligation is provided on a best-efforts basis. Revenue
recognized is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined using the
relative performance method, as of each reporting period.

If  the  Company  cannot  reasonably  estimate  the  level  of  effort  required  to  complete  our  performance  obligation  under  an  arrangement,  the
performance  obligation  is  provided  on  a  best-efforts  basis  and  we  can  reasonably  estimate  when  the  performance  obligation  ceases  or  the  remaining
obligations  become  inconsequential  and  perfunctory,  then  the  total  payments  under  the  arrangement,  excluding  royalties  and  payments  contingent  upon
achievement of substantive milestones, would be recognized as revenue on a straight-line basis over the period we expect to complete our performance
obligations. Revenue is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined
using the straight-line basis, as of the period ending date.

At  the  inception  of  each  arrangement  that  includes  development  milestone  payments,  the  Company  evaluates  the  probability  of  reaching  the
milestones and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue
reversal would not occur in the future, the associated milestone value is included in the transaction price. 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  and
therefore revenue recognized is constrained as management is unable to assert that a reversal of revenue would not be possible. The transaction price is
then  allocated  to  each  performance  obligation  on  a  relative  standalone  selling  price  basis,  for  which  the  Company  recognizes  revenue  as  or  when  the
performance  obligations  under  the  contract  are  satisfied.  At  the  end  of  each  subsequent  reporting  period,  the  Company  re-evaluates  the  probability  of
achievement of such development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such
adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

Amounts received prior to satisfying the above revenue recognition criteria are recorded as unearned revenue in our accompanying balance sheets.

Contract assets are generated when contractual billing schedules differ from revenue recognition timing. Contract assets represent a conditional
right to consideration for satisfied performance obligations that becomes a billed receivable when the conditions are satisfied. There were no contract assets
as of December 31, 2020 and 2019.

Contract liabilities result from arrangements where we have received payment in advance of performance under the contract. Changes in contract

liabilities are generally due to either receipt of additional advance payments or our performance under the contract.

We have the following amounts recorded for contract liabilities:

Unearned revenue

December 31

2020
2,101,325    $

2019
2,178,086 

  $

The contract liabilities amount disclosed above are primarily related to revenue being recognized on a straight-line basis over periods ranging from
23  to  30  years,  which,  in  management’s  judgment,  is  the  best  measure  of  progress  towards  satisfying  the  performance  obligations  and  represents  the
Company’s best estimate of the period of the obligation.

Revenue  recognized  from  contract  liabilities  during  the  years  ended  December  31,  2020  and  2019,  totaled  $76,761  and  $76,762,  respectively.

Revenue is expected to be recognized in the future from contract liabilities as the related performance obligations are satisfied.

Variable  Interest  Entities.  On  January  28,  2015,  the  Company  entered  into  a  Joint  Venture  Agreement  with  GtreeBNT,  a  shareholder  in  the
Company.  The  Joint  Venture  Agreement  provides  for  the  operation  of  the  joint  venture,  jointly  owned  by  the  Company  and  GtreeBNT,  which  is
commercializing  RGN-259  for  the  treatment  of  dry  eye  and  neurotrophic  keratitis  in  the  U.S.  and  Canada.  The  Company  has  determined  that  the  Joint
Venture is a “variable interest entity” since the total equity investment at risk is not sufficient to permit the Joint Venture to finance its activities without
additional subordinated financial support. Further, because of GtreeBNT’s majority equity stake in the Joint Venture, voting control, control of the board of
directors,  and  substantive  management  rights,  and  given  that  the  Company  does  not  have  the  power  to  direct  the  Joint  Venture’s  activities  that  most
significantly  impact  its  economic  performance,  the  Company  determined  that  it  is  not  the  primary  beneficiary  of  the  Joint  Venture  and  therefore  is  not
required to consolidate the Joint Venture. The Company reports its equity stake in the Joint Venture using the equity method of accounting because, while it
does not control the Joint Venture, the Company can exert significant influence over the Joint Venture’s activities by virtue of its board representation.

Because the Company is not obligated to fund the Joint Venture and has not provided any financial support and has no commitment to provide
financial support in the future to the Joint Venture, the carrying value of its investment in the Joint Venture is zero at both Decembers 31, 2020 and 2019.
As a result, the Company is not recognizing its share (38.5%) of the Joint Venture’s operating losses and will not recognize any such losses until the Joint
Venture produces net income (as opposed to net losses) and at that point the Company will reduce its share of the Joint Venture’s net income by its share of
previously suspended net losses. As of December 31, 2020, because it has not provided any financial support, the Company has no financial exposure as a
result of its variable interest in the Joint Venture.

Research  and  Development.  R&D  expenditures  are  expensed  as  incurred  and  are  subject  to  the  risks  and  uncertainties  associated  with  clinical
trials and the FDA review and approval process. As a result, these expenses could exceed our expectations, possibly materially. We are uncertain as to what
we will incur in future research and development costs for our clinical studies, as these amounts are subject to management's continuing assessment of the
economics of each individual research and development project and the internal competition for project funding.

Patent Costs.  Costs  related  to  filing  and  pursuing  patent  applications  are  recognized  as  general  and  administrative  expenses  as  incurred  since

recoverability of such expenditures is uncertain.

Income  Taxes.  Income  taxes  are  accounted  for  under  the  asset  and  liability  method.  Deferred  tax  assets  and  liabilities  are  recognized  for  the
estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their
respective tax basis 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.

The  ultimate  realization  of  deferred  tax  assets  is  dependent  upon  the  generation  of  future  taxable  income  during  the  periods  in  which  those
temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax
planning strategies in making that assessment. We recorded a full valuation allowance against all estimated net deferred tax assets at December 31, 2020
and 2019.

We  recognize  the  effect  of  income  tax  positions  only  if  those  positions  are  more  likely  than  not  of  being  sustained.  Recognized  income  tax
positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the
period in which the change in judgment occurs. Our policy for recording interest and penalties associated with audits is that penalties and interest expense
are recorded in provision for income taxes in our statements of operations.

We  have  significant  net  operating  loss  carryforwards  to  potentially  reduce  future  federal  and  state  taxable  income,  and  research  and
experimentation tax credit carryforwards available to potentially offset future federal and state income taxes. Use of our net operating loss and research and
experimentation credit carryforwards may be limited due to changes in our ownership as defined within Section 382 of the Internal Revenue Code.

Net Loss Per Common Share. Basic net loss per common share for 2020 and 2019 is based on the weighted average number of shares of common
stock outstanding during the years. Diluted loss per share is based on the weighted average number of shares of common stock outstanding during each
year  in  which  a  loss  is  incurred;  potentially  dilutive  shares  are  excluded  because  the  effect  is  antidilutive.  In  years  where  there  is  net  income,  diluted
income per share is based on the weighted average number of shares of common stock outstanding plus dilutive securities with a purchase or conversion
price  below  the  per  share  price  of  our  common  stock  on  the  last  day  of  the  year.  The  potentially  dilutive  securities  include  33,705,854  shares  and
31,075,178 shares in 2020 and 2019, respectively, reserved for the conversion of convertible debt or exercise of outstanding options and warrants.

Share-Based  Compensation.  We  measure  share-based  compensation  expense  based  on  the  grant  date  fair  value  of  the  awards  which  is  then
recognized over the period which service is required to be provided. We estimate the grant date fair value using the Black-Scholes option-pricing model
(“Black-Scholes”).  We  recognized  $332,003  and  $269,740  in  share-based  compensation  expense  for  the  years  ended  December  31,  2020  and  2019,
respectively.

Fair  Value  of  Financial  Instruments.  The  carrying  amounts  of  our  financial  instruments,  as  reflected  in  the  accompanying  balance  sheets,
approximate fair value. Financial instruments consist of cash and cash equivalents, accounts payable, and convertible debt and accrued interest. Because the
convertible  debt  with  an  interest  rate  of  5%  is  with  related  parties,  it  was  not  practicable  to  estimate  the  effect  of  subjective  risk  factors,  which  might
influence the value of the debt. The most significant of these risk factors include the lack of collateralization.

Recently Adopted Accounting Pronouncements. In June 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-07, Compensation –
Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This ASU expands the scope of Topic 718 to include
share-based payment transactions for acquiring goods and services from non-employees, and as a result, the accounting for share-based payments to non-
employees  will  be  substantially  aligned.  The  Company  adopted  ASU  2018-07  in  the  first  quarter  of  2019  and  the  adoption  of  this  ASU  did  not  have  a
material impact on its financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASC 842”), which amends the existing accounting standards for leases.
The new standard requires lessees to record an ROU asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases),
whereas under prior accounting standards, the Company’s lease portfolio consists of an operating lease and was not recognized on its balance sheets. The
new standard also requires expanded disclosures regarding leasing arrangements. The new standard was effective for the Company beginning January 1,
2019. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides an alternative modified transition method.
Under this method, the cumulative-effect adjustment to the opening balance of retained earnings is recognized on the date of adoption with prior periods
not  restated.  The  guidance  must  be  adopted  on  a  modified  retrospective  basis  and  provides  for  certain  practical  expedients.  We  adopted  this  guidance
effective January 1, 2019, using the following practical expedients:

•

•

We did not reassess if any expired or existing contracts are, or contain, leases.

We did not reassess the classification of any expired or existing leases.

Additionally, we made ongoing accounting policy elections whereby we (i) do not recognize ROU assets or lease liabilities for short-term leases

(those with original terms of 12 months or less) and (ii) combine lease and non-lease elements of our operating leases.

Upon adoption of the new guidance on January 1, 2019, we recorded a ROU asset of approximately $60,000 (net of existing deferred rent liability)
and recognized a lease liability of approximately $65,000, with no resulting cumulative effect adjustment to accumulated deficit. In June 2020, we renewed
our office lease for two years and we recorded a ROU asset of approximately $82,000 and recognized a lease liability of approximately $82,000.

Accounting  Standard  Not  Yet  Adopted.  In  December  2019,  the  FASB  issued  ASU  No.  2019-12,  Income  Taxes  (Topic  740):  Simplifying  the
Accounting for Income Taxes, which simplifies the accounting for income taxes. The new guidance removes certain exceptions to the general principles for
income taxes and also improves consistent application of accounting by clarifying or amending existing guidance. The new standard is effective for fiscal
years beginning after December 15, 2020, and interim periods within those years. We are currently evaluating the impact that the new guidance will have
on our financial statements. The Company has evaluated all other issued and unadopted ASUs and believes the adoption of these standards will not have a
material impact on its results of operations, financial position or cash flows.

FAIR VALUE MEASUREMENTS

The  authoritative  guidance  for  fair  value  measurements  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  the  most  advantageous  market  for  the  asset  or  liability  in  an  orderly  transaction  between  market
participants  on  the  measurement  date.  Market  participants  are  buyers  and  sellers  in  the  principal  market  that  are  (i)  independent,  (ii)  knowledgeable,
(iii) able to transact, and (iv) willing to transact. The guidance describes a fair value hierarchy based on the levels of inputs, of which the first two are
considered observable and the last unobservable, that may be used to measure fair value which are the following:

•

•

•

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

Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities.

Level 3 — Unobservable inputs.

As of December 31, 2020, and 2019, our only qualifying assets that required measurement under the foregoing fair value hierarchy were funds

held in our Company bank accounts included in cash and cash equivalents valued at $427,898 and $639,916, respectively, using Level 1 inputs.

LICENSES, INTELLECTUAL PROPERTY, AND RELATED PARTY TRANSACTIONS

We have filed numerous additional patent applications covering various compositions, uses, formulations and other components of Tb4, as well as

to novel peptides resulting from our research efforts. Some of these patents have been issued, while many patent applications are still pending.

We  have  also  entered  into  an  agreement  with  a  university  under  the  terms  of  which  we  have  received  an  exclusive  license  to  technology  and
intellectual  property.    The  agreement,  which  is  generally  cancelable  by  us,  provided  for  the  payment  of  a  license  issue  fee  and/or  minimum  annual
payments.  The initial license fee of $25,000 was paid in 2010 and no minimum fees were due for the year ended December 31, 2011. Beginning in 2012,
minimum  annual  maintenance  fees  are  $5,000  annually  which  was  paid  in  2012  but  has  not  been  paid  since.  In  addition,  the  agreements  provide  for
payments upon the achievement of certain milestones in product development.  The agreement also requires us to fund certain costs associated with the
filing and prosecution of patent applications. In February 2013, this agreement was amended to include additional technology and intellectual property. The
expanded  license  does  not  require  payment  of  an  initial  license  fee  or  additional  annual  maintenance  fees  but  will  be  subject  to  payments  upon  the
achievement of certain milestones for a product developed under the amended license of the additional technology and intellectual property.

All license fees are included in Research and Development in the accompanying statements of operations.

In 2012, we entered into a license agreement (the “Agreement”) with Lee’s Pharmaceutical (HK) Limited (“Lee’s”), headquartered in Hong Kong,
for  the  license  of  Thymosin  Beta  4  in  any  pharmaceutical  form,  including  our  RGN-259,  RGN-352  and  RGN-137  product  candidates,  in  China,  Hong
Kong, Macau and Taiwan. Under the Agreement, we are eligible to receive milestone payments and royalties, ranging from low double digit to high single
digit percentages of any commercial sales of the licensed products. Lee’s will pay for all developmental costs associated with each product candidate. We
will provide Tß4 to Lee’s at no charge for a Phase 2 ophthalmic clinical trial and will provide Tß4 to Lee’s for all other developmental and clinical work at
a  price  equal  to  our  cost.  We  will  also  have  the  right  to  exclusively  license  any  improvements  made  by  Lee’s  to  RegeneRx’s  products  outside  of  the
licensed  territory.  Lee’s  paid  us  $200,000  upon  signing  of  a  term  sheet  in  March  2012,  and  Lee’s  paid  us  an  additional  $200,000  upon  signing  of  the
definitive license agreement. The Company is accounting for the license agreement as a revenue arrangement. Since participation in the joint development
committee is required it was deemed to be a material promise. Management has concluded that the participation in the joint development committee is not
distinct from other promised goods and services. The Company evaluated the promised goods and services under the agreement and determined that there
was one combined performance obligation representing a series of distinct goods and services including the license to research, develop and commercialize
Tß4 in any pharmaceutical form and participation in the joint development committee. To date, management has not been able to reasonably measure the
outcome of the performance obligation, but still expects to recover the costs incurred in satisfying the performance obligation. Accordingly, the Company
has  deferred  all  revenue  until  such  time  that  it  can  reasonably  measure  the  outcome  of  the  performance  obligation  or  until  the  performance  obligation
becomes  onerous.  As  of  December  31,  2020  and  2019,  we  have  unearned  revenue  totaling  $400,000  pursuant  to  this  Agreement.  Revenue  will  be
recognized for future royalty payments as they are earned. In February 2019, the license agreement was amended and assigned by Lee’s to their affiliate,
Zhaoke Ophthalmology Pharmaceutical Limited. There are no economic changes to the Agreement.

On March 7, 2014, we entered into license agreements with GtreeBNT Co., Ltd. The two Licensing Agreements are for the license of territorial

rights to two of our Thymosin Beta 4-based products candidates, RGN-259 and RGN-137.

Under  the  license  agreement  for  RGN-259,  our  preservative-free  eye  drop  product  candidate,  GtreeBNT  will  have  the  right  to  develop  and
commercialize  RGN-259  in  Asia  (excluding  China,  Hong  Kong,  Taiwan,  and  Macau).  The  rights  will  be  exclusive  in  Korea,  Japan,  Australia,  New
Zealand,  Brunei,  Cambodia,  East  Timor,  Indonesia,  Laos,  Malaysia,  Mongolia,  Myanmar  (Burma),  Philippines,  Singapore,  Thailand,  Vietnam,  and
Kazakhstan, and semi-exclusive in India, Pakistan, Bangladesh, Bhutan, Maldives, Nepal, Sri Lanka, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan,
collectively, the Territory (the “259 Territory”). Under the 259 license agreement we are eligible to receive aggregate potential milestone payments of up to
$3.5  million.  In  addition,  we  are  eligible  to  receive  royalties  of  a  low  double  digit  percentage  of  any  commercial  sales  of  the  licensed  product  sold  by
GtreeBNT in the 259 Territory.

Under  the  license  agreement  for  RGN-137,  our  topical  dermal  gel  product  candidate,  GtreeBNT  will  have  the  exclusive  right  to  develop  and
commercialize RGN-137 in the U.S. (the “137 Territory”). Under the 137 agreement we are eligible to receive aggregate potential milestone payments of
up to $3.5 million. In addition, we are eligible to receive royalties of a low double digit percentage of any commercial sales of the Company’s licensed
product  sold  by  GtreeBNT  in  the  137  Territory.  In  August  2017,  we  amended  the  license  agreement  for  RGN-137  held  by  GtreeBNT.  Under  the
amendment, the 137 Territory was expanded to include Europe, Canada, South Korea, Australia and Japan. Under the agreement, the Company received a
series of non-refundable payments and is entitled to receive royalties on the future sales of products. The Company is accounting for the license agreement
as a revenue arrangement. Since participation in the joint development committee is required, it was deemed to be a material promise. Management has
concluded that the participation in the joint development committee is not distinct from other promised goods and services. The Company evaluated the
promised  goods  and  services  under  the  agreement  and  determined  that  there  was  one  combined  performance  obligation  representing  a  series  of  distinct
goods and services including the license to research, develop and commercialize RGN-137 and participation in the joint development committee. Revenue
is being recognized on a straight-line basis over a period of 23 years, which, in management’s judgment, is the best measure of progress towards satisfying
the  performance  obligation  and  represents  the  Company’s  best  estimate  of  the  period  of  the  obligation.  As  of  December  31,  2020  and  2019,  we  have
unearned revenue totaling $684,058 and $718,840, respectively, pursuant to this agreement. Revenue will be recognized for future royalty payments as they
are earned.

Each license agreement contains diligence provisions that require the initiation of certain clinical trials within certain time periods that, if not met,
would result in the loss of rights or exclusivity in certain countries. GtreeBNT will pay for all developmental costs associated with each product candidate.
We have the right to exclusively license any improvements made by GtreeBNT to our products outside of the licensed territory on a royalty free basis. The
two firms have created a joint development committee and continue to discuss the development of the licensed products and share information relating
thereto. Both companies will also share all non-clinical and clinical data and other information related to development of the licensed product candidates.

On January 28, 2015, the Company entered into the Joint Venture Agreement with GtreeBNT, a shareholder in the Company. The Joint Venture
Agreement provides for the creation of the Joint Venture, jointly owned by the Company and GtreeBNT, which is commercializing RGN-259 for treatment
of dry eye and neurotrophic keratitis in the U.S. and Canada.

GtreeBNT is solely responsible for funding all the product development and commercialization efforts of the Joint Venture. GtreeBNT made an
initial contribution of $3 million in cash and received an initial equity stake of 51%. RegeneRx’s ownership interest in ReGenTree was reduced to 38.5%
when the Clinical Study Report was filed for the Phase 2/3 dry eye clinical trial. Based on when, and if, certain additional development milestones are
achieved  in  the  U.S.  with  RGN-259,  our  equity  ownership  may  be  incrementally  reduced  to  between  38.5%  and  25%,  with  25%  being  the  final  equity
ownership upon approval of a BLA for DES in the U.S. In addition to our equity ownership, RegeneRx retains a royalty on net sales that varies between
single and low double digits, depending on whether commercial sales are made by ReGenTree or a licensee. In the event ReGenTree is acquired or there is
a change of control that occurs following achievement of a BLA, RegeneRx shall be entitled to a minimum of 40% of all proceeds paid or payable and will
forgo any future royalties. The Company is not required or otherwise obligated to provide financial support to the Joint Venture.

F-13

 
 
 
 
 
 
 
 
The Joint Venture is responsible for executing all development and commercialization activities under the license agreement, which activities will
be directed by a joint development committee comprised of representatives of the Company and GtreeBNT. The license agreement has a term that extends
to  the  later  of  the  expiration  of  the  last  patent  covered  by  the  agreement  or  25  years  from  the  first  commercial  sale  under  the  agreement.  The  license
agreement may be earlier terminated if the Joint Venture fails to meet certain commercialization milestones, if either party breaches the license agreement
and fails to cure such breach, as a result of government action that limits the ability of the Joint Venture to commercialize the product, as a result of a
challenge to a licensed patent, following termination of the license between the Company and certain agencies of the United States federal government, or
upon the bankruptcy of either party.

Under the license agreement, the Company received $1.0 million in up-front payments and is entitled to receive royalties on the Joint Venture’s
future sales of products. On April 6, 2016, we received $250,000 from ReGenTree and executed an amendment to the license agreement on April 28, 2016.
Under the amendment the territorial rights were expanded to include Canada. The Company is accounting for the license agreement with the Joint Venture
as a revenue arrangement. Since participation in the joint development committee is required, it was deemed to be a material promise. Management has
concluded that the participation in the joint development committee is not distinct from other promised goods and services. The Company evaluated the
promised goods and services under the license agreements and determined that there was one combined performance obligation representing a series of
distinct goods and services including the license to research, develop and commercialize RGN-259 and participation in the joint development committee.
Revenue is being recognized on a straight-line basis over a period of 30 years, which, in management’s judgment, is the best measure of progress towards
satisfying the performance obligation and represents the Company’s best estimate of the period of the obligation. As of December 31, 2020 and 2019, we
have  unearned  revenue  totaling  $1,017,267  and  $1,059,246,  respectively,  pursuant  to  this  agreement.  Revenue  will  be  recognized  for  future  royalty
payments as they are earned.

CONVERTIBLE NOTES

2014 Convertible Notes

On January 7, 2014, we completed a private placement of convertible notes raising an aggregate of $55,000 in gross proceeds (the “January 2014
Notes”).   The January 2014 Notes bore interest at a rate of 5% per annum, mature sixty (60) months after their date of issuance and were convertible into
shares of our common stock at a conversion price of six cents ($0.06) per share (subject to adjustment as described in the January 2014 Notes) at any time
prior to repayment, at the election of the investor.  In the aggregate, the January 2014 Notes were initially convertible into up to 916,667 shares of our
common stock.

At any time prior to maturity of the January 2014 Notes, with the consent of the holders of a majority in interest of the January 2014 Notes, we
could prepay the outstanding principal amount of the January 2014 Notes plus unpaid accrued interest without penalty.  Upon the commission of any act of
bankruptcy by the Company, the execution by the Company of a general assignment for the benefit of creditors, the filing by or against the Company of a
petition in bankruptcy or any petition for relief under the federal bankruptcy act or the continuation of such petition without dismissal for a period of 90
days or more, or the appointment of a receiver or trustee to take possession of the property or assets of the Company, the outstanding principal and all
accrued interest on the January 2014 Notes would accelerate and automatically become immediately due and payable.

The investors in the offering included two current and one former member of the Board of Directors. The principal amounts of their respective

January 2014 Notes were as set forth below:

25,000 
10,000

The Company evaluated the terms of the January 2014 Notes which contain a down round provision under which the conversion price could be
decreased  as  a  result  of  future  equity  offerings,  as  defined  in  the  January  2014  Notes.    The  adjustment  would  reduce  the  conversion  price  of  the
January 2014 Notes to be equivalent to that of the newly issued stock or stock-related instruments.  As a result, the Company concluded that the conversion
feature represented an embedded conversion feature for accounting purposes and should be recognized as a derivative liability, requiring a mark-to-market
adjustment at the end of each reporting period until the related January 2014 Notes were settled. The bifurcated liability of $55,000 was recorded on the
date of issuance which resulted in a residual debt value of $0. The discount related to the embedded feature is being accreted back to debt through the
maturity  of  the  notes.  The  January  2014  Notes  matured,  and  the  holders  elected  to  convert  the  note  balances  of  $55,000  and  accrued  interest  of
approximately $14,000 into common stock in January 2019.

2019 Convertible Notes

In February 2019, we sold a series of convertible promissory notes to management, the Company’s Board of Directors and accredited investors
including Essetifin S.p.A., our largest stockholder. The sale of the notes resulted in gross proceeds to the Company of $1,300,000 over two closings (the
“2019 Notes”). The first closing in the amount of $650,000 occurred in February 2019 and the second closing, also in the amount of $650,000, occurred on
May 13, 2019 after the Company provided notice of the enrollment of the first patent in the ARISE-3 clinical trial in DES sponsored by ReGenTree. The
2019 Notes will mature on March 1, 2024. The 2019 Notes bear interest at a rate of five percent (5%) per annum and are convertible into shares of our
common stock at a conversion price of twelve cents ($0.12) per share (subject to adjustment as described in the 2019 Notes) at any time prior to repayment,
at the election of the investors. In the aggregate, the 2019 Notes issued in both closings are convertible into up to 10,833,333 shares of our common stock
excluding interest.

At any time prior to maturity of the 2019 Notes, with the consent of the holders of a majority in interest of the 2019 Notes, we can prepay the
outstanding principal amount of the 2019 Notes plus unpaid accrued interest without penalty. The outstanding principal and all accrued interest on the 2019
Notes will accelerate and automatically become immediately due and payable upon the occurrence of certain events of default.

In  connection  with  the  issuance  of  the  2019  Notes  we  also  issued  warrants  to  each  investor.  The  warrants  are  exercisable  for  an  aggregate  of
8,125,000 shares of common stock with an exercise price of eighteen cents ($0.18) per share for a period of five years (the “2019 Warrants”). The relative
fair  value  of  the  2019  Warrants  issued  was  $348,443  calculated  using  the  Black-Scholes-Merton  valuation  model  value  of  $0.06  with  an  expected  and
contractual life of five years, an assumed volatility of 67.86%, and a risk-free interest rate of 2.49%. The 2019 Warrants are classified in equity.

The Company allocated $348,443 of the gross proceeds to the warrants, on a relative fair value basis. In addition, because the effective conversion
price of the 2019 Notes was less than the fair value of the underlying common stock on the issuance date, we allocated the intrinsic value of that feature to
additional paid-in capital. The debt discount created by the 2019 Warrants and beneficial conversion feature is amortized over the term of the 2019 Notes as
additional interest expense using the effective interest method.

2020 Convertible Notes

In October 2020, we sold a series of convertible promissory notes to management, the Company’s Board of Directors and accredited investors
including Essetifin S.p.A., our largest stockholder. The sale of the notes resulted in gross proceeds to the Company of $500,000 (the “2020 Notes”). The
2020 Notes will mature on October 15, 2025. The 2020 Notes bear interest at a rate of five percent (5%) per annum and are convertible into shares of our
common  stock  at  a  conversion  price  of  thirty-six  cents  ($0.36)  per  share  (subject  to  adjustment  as  described  in  the  2020  Notes)  at  any  time  prior  to
repayment, at the election of the investors. In the aggregate, the 2020 Notes are convertible into up to 1,391,982 shares of our common stock excluding
interest.

At any time prior to maturity of the 2020 Notes, with the consent of the holders of a majority in interest of the 2020 Notes, we can prepay the
outstanding principal amount of the 2020 Notes plus unpaid accrued interest without penalty. The outstanding principal and all accrued interest on the 2020
Notes will accelerate and automatically become immediately due and payable upon the occurrence of certain events of default.

In  connection  with  the  issuance  of  the  2020  Notes  we  also  issued  warrants  to  each  investor.  The  warrants  are  exercisable  for  an  aggregate  of
1,043,988 shares of common stock with an exercise price of forty-five cents ($0.45) per share for a period of five years (the “2020 Warrants”). The relative
fair  value  of  the  2020  Warrants  issued  was  $176,573  calculated  using  the  Black-Scholes-Merton  valuation  model  value  of  $0.26  with  an  expected  and
contractual life of five years, an assumed volatility of 74.6%, and a risk-free interest rate of 0.32%. The 2020 Warrants are classified in equity.

The Company allocated $176,573 of the gross proceeds to the warrants, on a relative fair value basis. In addition, because the effective conversion
price of the 2020 Notes was less than the fair value of the underlying common stock on the issuance date, we allocated $289,045, the intrinsic value of that
feature to additional paid-in capital. The debt discount created by the 2020 Warrants and beneficial conversion feature is amortized over the term of the
2020 Notes as additional interest expense using the effective interest method.

Common Stock. In January 2019, the January 2014 Notes matured, and the holders elected to convert the note balances and accrued interest into

common stock. As a result, we issued 1,149,016 shares of common stock.

On  March  2,  2018,  we  entered  into  the  Reprice  Agreement  with  Sabby  Healthcare  Master  Fund,  Ltd.,  and  Sabby  Volatility  Warrant  Master
Fund, Ltd. (collectively, “Sabby”). In connection with that certain securities purchase agreement between the Company and Sabby dated June 27, 2016 (the
“Purchase Agreement”) we also issued to Sabby warrants to purchase 5,147,059 shares of common stock (the “Warrant Shares”) at an exercise price of
$0.51 per share (the “Sabby Warrants”). Under the terms of the Reprice Agreement, in consideration of Sabby exercising in full all of the Sabby Warrants
(the “Warrant Exercise”), the exercise price per share of the Sabby Warrants was reduced to $0.20 per share. We received gross proceeds of approximately
$1,029,000 from the warrant reprice transaction. In addition, and as further consideration, we issued to Sabby warrants to purchase up to 3,860,294 shares
of  common  stock  at  an  exercise  price  of  $0.2301  per  share,  the  closing  bid  price  for  the  Company’s  Common  Stock  on  February  28,  2018  (the
“March Warrants”).

The exercise price under the March Warrants is subject to a limited anti-dilution provision, such that in the event the Company makes an issuance
of common stock (subject to customary exceptions) at a price per share less than the applicable exercise price of the March Warrants, the exercise price of
the March Warrants will be reduced to the price per share applicable to such new issuance but will not adjust to an exercise price below $0.125. As a result
of the issuance of the 2019 Notes and Warrants, the exercise price of the March Warrants was adjusted to $0.125 per share. The estimated fair value of the
effect of the exercise price adjustment of $82,566 is reflected as a dividend to Sabby for the year end December 31, 2019.

Subsequent  to  the  reduction  of  the  exercise  price  of  the  March  Warrants  to  $0.125  in  2019,  Sabby  exercised  warrants  for  925,000  shares  of
common stock and the Company received exercise proceeds of $115,625. Sabby exercised additional warrants on April 23, 2019 for 1,000,000 shares of
common  stock  and  the  Company  received  exercise  proceeds  of  $125,000.  Sabby  exercised  their  remaining  warrants  on  January  17,  2020  for  1,935,294
shares of common stock and the Company received exercise proceeds of $241,911.

Registration Rights Agreements. In connection with the sale of certain equity instruments, we have entered into Registration Rights Agreements.
Generally, these Agreements required us to file registration statements with the Securities and Exchange Commission to register common shares to permit
re-sale of common shares previously sold under an exemption from registration or to register common shares that may be issued on exercise of outstanding
warrants.

The Registration Rights Agreements usually require us to pay penalties for any failure or time delay in filing or maintaining the effectiveness of
the required registration statements. These penalties are usually expressed as a fixed percentage, per month, of the original amount we received on issuance
of  the  common  shares,  options  or  warrants.  While  to  date  we  have  not  incurred  any  penalties  under  these  agreements,  if  a  penalty  is  determined  to  be
probable, we would recognize the amount as a contingent liability and not as a derivative instrument.

Share-Based Compensation. We recognized $332,003 and $269,740 in stock-based compensation expense for the years ended December 31, 2020
and  2019,  respectively.  We  expect  to  recognize  the  compensation  cost  related  to  non-vested  options  as  of  December  31,  2020  of  $423,000  over  the
weighted average remaining recognition period of 1.27 years.

Stock Option and Incentive Plans. On June 13, 2018, at our Annual Meeting of Stockholders, our stockholders approved the 2018 Equity Incentive
Plan  (the  “2018  Plan”).  The  terms  of  the  2018  Plan  provide  for  the  discretionary  grant  of  incentive  stock  options,  nonstatutory  stock  options,  stock
appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, other stock awards and performance cash awards to our
employees, directors and consultants. The total number of shares of our common stock reserved for issuance under the 2018 Plan was initially 5,000,000
shares of common stock with additional shares being available for grant under the plan annually in an amount equal to 2% of the then outstanding shares of
common  stock  on  July  1  of  each  calendar  year.  Pursuant  to  this  plan  provision,  on  July  1,  2020,  2,668,836  additional  shares  of  common  stock  became
available for grant under the 2018 Plan. On July 1, 2019, 2,630,130 additional shares of common stock became available for grant under the 2018 Plan.

We have previously adopted two equity incentive plans, known as the 2000 Equity Incentive Plan, or the 2000 Plan, and the 2010 Equity Incentive
Plan, or the 2010 Plan. Both the 2000 Plan and the 2010 Plan have a term of ten years, with the 2000 Plan already expired and the 2010 Plan expired in
July 2020. No further awards may be granted under the 2010 Plan with the approval of the 2018 Plan. All outstanding option awards granted under the
2010 Plan will continue to be subject to the terms and conditions as set forth in the agreements evidencing such option awards and the terms of the 2010
Plan. Shares remaining available for issuance under the shares reserved under the 2010 Plan will not be subject to future awards under the 2018 Plan, and
shares subject to outstanding awards under the 2010 Plan that are terminated or forfeited in the future will not be subject to future awards under the 2018
Plan. All outstanding option awards granted under the 2000 Plan have expired.

Determining the Fair Value of Options. We use the Black-Scholes valuation model to estimate the fair value of options granted. Black-Scholes
considers a number of factors, including the market price and volatility of our common stock. We used the following forward-looking range of assumptions
to value each stock option granted to employees, directors and consultants during the years ended December 31, 2020 and 2019:

Dividend yield
Risk-free rate of return
Expected life in years
Volatility
Forfeiture rate

   2020  

  2019  

0.0%  
0.33%  
5.88 

0.0%
2.15%
5.88 

   74.57%   93.59%
2.6%

2.6%  

Our dividend yield assumption is based on the fact that we have never paid cash dividends and do not anticipate paying cash dividends in the
foreseeable future. Our risk-free interest rate assumption is based on yields of U.S. Treasury notes in effect at the date of grant. Our expected life represents
the  period  of  time  that  options  granted  are  expected  to  be  outstanding  and  is  calculated  in  accordance  with  the  Securities  and  Exchange  Commission
(“SEC”) guidance provided in the SEC’s Staff Accounting Bulletin (“SAB”) 107 and SAB 110, using a “simplified” method. The Company has used the
simplified method and will continue to use the simplified method as it does not have sufficient historical exercise data to provide a reasonable basis upon
which to estimate an expected term. Our volatility assumption is based on reviews of the historical volatility of our common stock. Using Black-Scholes
and  these  factors,  the  weighted  average  fair  value  of  stock  options  granted  to  employees  and  directors  was  $0.19  and  $0.16  for  the  years  ended
December 31, 2020 and 2019, respectively. We do not record tax-related effects on stock-based compensation given our historical and anticipated operating
experience and offsetting changes in our deferred income tax valuation allowance which fully reserves against our deferred tax assets.

At December 31, 2020, we had net operating loss carryforwards for Federal income tax purposes of approximately $51.1 million and research and
research and experimental tax credit carryforwards of approximately $2.3 million, which are available to offset future federal income. Approximately $47.9
million of the net operating loss carryforwards, generated prior to 2018, expires in increments through 2037, while carryforwards generated in 2018 or later
do not expire.

Section 382 of the Internal Revenue Code imposes substantial restrictions on the utilization of net operating losses and tax credits in the event of a
corporation’s ownership change. During 2009, the Company completed a preliminary study to compute any limits on the net operating losses and credit
carryforwards  for  purposes  of  Section  382.  It  was  determined  that  the  Company  experienced  a  cumulative  change  in  ownership,  as  defined  by  the
regulations, in 2002. This change in ownership triggers an annual limitation on the Company’s ability to utilize certain U.S. federal and state net operating
loss carryforwards and research tax credit carryforwards, resulting in the potential loss of approximately $9.8 million of net operating loss carryforwards
and  $0.2  million  in  research  credit  carryforwards.  The  Company  has  reduced  the  deferred  tax  assets  associated  with  these  carryforwards  in  its  balance
sheets. The Company believes that the future use of net operating loss-es and tax credits presented above may be further reduced as a result of additional
ownership changes subsequent to 2009.

The provision for income taxes on earnings subject to income taxes differs from the statutory federal rate for the years ended December 31, 2020

and 2019, due to the following:

As discussed in Note 2, we recognize the effect of income tax positions only if those positions are more likely than not of being sustained. At
December 31, 2020 and 2019, we had no gross unrecognized tax benefits. We do not expect any significant changes in unrecognized tax benefits over the
next 12 months. In addition, we did not recognize any interest or penalties related to uncertain tax positions at December 31, 2020 and 2019.

The 2007 through 2019 tax years generally remain subject to examination by federal and most state tax authorities. In addition, we would remain

open to examination for earlier years if we were to utilize net operating losses or tax credit carryforwards that originated prior to 2012.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was signed into law in response to the COVID-
19  pandemic.  The  CARES  Act  provides  numerous  tax  provisions  and  stimulus  measures,  including  temporary  changes  regarding  the  prior  and  future
utilization of net operating losses, temporary changes to the prior and future limitations on interest deductions, and technical corrections from prior tax
legislation for tax depreciation of certain qualified improvement property. The Company has evaluated the provisions of the CARES Act relating to income
taxes which will result in adjustments to certain deferred tax assets and liabilities. Due to the Company’s U.S. valuation allowance, the Company noted the
provisions of the CARES Act did not have a material impact on its financial statements.

LEASES

In June 2020, we amended our office lease agreement, and the term has been extended through July 2022. During the extended term, our rental
payments will be approximately $4,200 per month. We had previously amended the office lease to extend through July 2020. Our facility lease is our only
existing  lease  as  of  December  31,  2020  and  is  classified  as  an  operating  lease.  The  discount  rate  used  in  the  calculation  of  our  lease  liability  is
approximately 20%, which is based on our estimate of the rate of interest that we would have to pay to borrow on a collateralized basis over a similar term
and amount equal to the lease payments in a similar economic environment as the lease does not provide an implicit rate.

The following table summarizes the Company’s recognition of its operating lease as of December 31, 2020:

PROMISSORY NOTE

On April 24, 2020, the Company entered into a Promissory Note (the “Loan”) with PNC Bank (the “Bank”) pursuant to the Paycheck Protection

Program (the “PPP”) of the CARES Act administered by the U.S. Small Business Administration. The principal amount of the Loan is $55,400.

In accordance with the requirements of the CARES Act, the Company used the proceeds from the Loan in accordance with the requirements of the
PPP to cover certain qualified expenses, including payroll costs, rent and utility costs. Interest accrues on the Loan at the rate of 1.00% per annum. The
Company may apply for forgiveness of amount due under the Loan, in an amount equal to the sum of qualified expenses under the PPP, which include
payroll costs, rent obligations, and covered utility payments incurred during the forgiveness period following disbursement of the Loan.

Subject to any forgiveness under the PPP, the Loan matures two years following the date of issuance of the Loan and includes a period for the first
six months during which time required payments of interest and principal are deferred. In June 2020, the Flexibility Act which amended the CARES Act
was signed into law. The Flexibility Act provides that if a borrower does not apply for forgiveness of a loan within 10 months after the last day of the
measurement period (“covered period”), the PPP loan is no longer deferred, and the borrower must begin paying principal and interest. In addition, the
Flexibility Act extended the length of the covered period from eight weeks to 24 weeks from receipt of proceeds, while allowing borrowers that received
PPP loans before June 5, 2020 to determine, at their sole discretion, a covered period of either eight weeks or 24 weeks.

No interest or principal will be due during the deferral period, although interest will continue to accrue over this period. After the deferral period
and after taking into account any loan forgiveness applicable to the Note, any remaining principal and accrued interest will be payable in substantially equal
monthly installments over the remaining term of the Note. The Loan may be prepaid at any time prior to maturity with no prepayment penalties. The Loan
provides  for  customary  events  of  default,  including,  among  others,  those  relating  to  breaches  of  their  obligations  under  the  Loan,  including  a  failure  to
make payments, any bankruptcy or similar proceedings involving the Company, and certain material effects on the Company’s ability to repay the Loan.
The Company did not provide any collateral or guarantees for the Loan.

12. COMMITMENTS

Employment Continuity Agreements. We have entered into employment contracts with our executive officers which provide for severance if the
executive is dismissed without cause or under certain circumstances after a change of control in our ownership. At December 31, 2020, these obligations, if
triggered, could amount to a maximum of approximately $170,000.

Designed  such  internal  control  over  financial  reporting,  or  caused  such  internal  control  over  financial  reporting  to  be  designed  under  our

external purposes in accordance with generally accepted accounting principles;

Evaluated  the  effectiveness  of  the  registrant's  disclosure  controls  and  procedures  and  presented  in  this  report  our  conclusions  about  the
effectiveness of the disclosure controls and procedures, as of the end of the period covered by this report based on such evaluation; and

Disclosed in this report any change in the registrant's internal control over financial reporting that occurred during the registrant's most recent
fiscal  quarter  (the  registrant's  fourth  fiscal  quarter  in  the  case  of  an  annual  report)  that  has  materially  affected,  or  is  reasonably  likely  to
materially affect, the registrant's internal control over financial reporting; and

The registrant's other certifying officer and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the
registrant's auditors and the audit committee of the registrant's board of directors (or persons performing the equivalent functions):

All  significant  deficiencies  and  material  weaknesses  in  the  design  or  operation  of  internal  control  over  financial  reporting  which  are
reasonably likely to adversely affect the registrant's ability to record, process, summarize and report financial information; and

Any  fraud,  whether  or  not  material,  that  involves  management  or  other  employees  who  have  a  significant  role  in  the  registrant's  internal
control over financial reporting.
