Dear�Shareholders:�
�
We� have� been� hard� at� work� in� the� clinic� throughout� all� of� 2014,� continuing� our� efforts� to� develop�
oncology� therapies� with� the� potential� to� impact� the� way� cancer� patients� are� treated.� � It� has� truly�
been�a�busy�and�productive�year�for�Rexahn.�After�refocusing�the�Company�in�2013�to�concentrate�in�
the� oncology� space,� we� have� maintained� the� strategy� of� executing� on� the� research� and�
development� of� three� separate� oncology� programs:� Supinoxin™,� RX�3117,� and� Archexin®.� We�
initiated� early� stage� trials� in� each� of� these� programs� in� 2013� and� early� 2014,� and� we� continue� to�
enroll�patients�in�each�study�today.�We�believe�that�data�from�these�trials�will�be�available�in�2015.�
We�are�committed�to�the�development�of�our�diversified�pipeline�to�deliver�the�level�of�success�that�

Pipeline Overview 

Rexahn’s diversified oncology portfolio includes three compounds in human clinical trials.  Each 
compound  has  shown  to  directly  target  cancer  cells  while  sparing  healthy  tissues.  Our  clinical 
trials  are  designed  to  evaluate  the  safety  and  efficacy  associated  with the  specific  targeting  of 
cancer  cells.    In  preclinical  studies,  these  compounds  were  effective  against  numerous  drug-
resistant  cancers  and  work  synergistically  with  FDA-approved  cancer  treatments  to  increase 
efficacy. We are also developing specific biomarkers to help identify patients whom will be most 
responsive to our therapies, thereby enabling targeted, personalized medicine. 

I. 

 Our three clinical development programs are: 

Supinoxin™  (Phase  I)  is  a  potent,  orally  bioavailable,  first-in-class  small  molecule  that 
inhibits the growth of cancer cells by targeting phosphorylated-p68, which is found only 
in cancer cells.  

RX-3117  (Phase  Ib)  is  a  next-generation,  cancer  cell  specific  nucleoside  agent  that 
exhibits  high  oral  bioavailability.  It  may  have  a  superior  safety  profile  compared  to 
gemcitabine, one of the most widely used chemotherapy drugs. In addition, RX-3117 has 
shown  activity  against  gemcitabine-resistant  cancers  in  preclinical  human  and  animal 
studies. 

Archexin® (Phase IIa) is a  best-in-class agent that blocks the activated form of Akt-1, a 
protein kinase that plays a central role in drug resistance and the uncontrolled growth of 
cancer tumor cells.   

Supinoxin™  
Rexahn is developing Supinoxin as an orally-administered, first-in-class phosphorylated-p68 inhibitor 
with great potential to be effective against solid tumors. Phosphorylated-p68 is a protein that plays a 
key role in cancer growth, progression and metastasis in the most difficult cancers, representing the 
fastest  growing  drug-treatable  population.  Over-expression  of  phosphorylated-p68  has  been 
observed  in  solid  tumors, such  as colon,  breast, head and  neck squamous cell carcinomas, prostate 
and ovarian cancers and multiple myeloma. However, phosphorylated-p68 is not present in healthy, 
non-cancerous tissue.  

The Phase I clinical trial for patients with solid cancer tumors commenced in August of 2013, and we 
expect  to  have  results  in  the  first  half  of  2015.  Patients  receive  Supinoxin  once  weekly  for  3  weeks 
followed by 1 week without treatment, and have the ability to continue on the drug for up to eight 
cycles of treatment. The decision to enroll the next group of patients and escalate the dose  is made 
after  one  cycle  of  treatment,  based  on  safety  and  tolerability  seen  in  the  previous  dosing  group. 
Patients are assessed for tumor progression by CT or MRI scan prior to the start of therapy and after 
every  two  cycles  of  therapy.  Rexahn  expects  to  complete  enrollment  of  patients  in  the  first  half  of 
2015, with data available soon after. 

Initial  results  reported  in  March  2014,  indicated  that  Supinoxin  is  safe  and  well-tolerated  over  the 
dose  range  tested  in  cancer  patients  with  solid  tumors  who  have  received  multiple  cycles  of 

 
 
 
  
  
 
  
 
 
 
treatment. In addition, the pharmacokinetic profile and oral bioavailability of Supinoxin is consistent 
with preclinical studies.  

The study is ongoing and the maximum tolerated dose has not yet been determined. Seven dosing 
cycles  have  been  completed  (25,  50,  100,  150,  225,  300  and  425  mg)  and  no  drug  related  adverse 
events  have  been  reported.  Pharmacokinetic  analysis  has  shown  that  Supinoxin  displays  dose-
proportional exposure and an estimated oral bioavailability of 51%.  

RX-3117 
RX-3117  is  a  next-generation,  cancer  cell  specific  nucleoside  compound.  RX-3117  inhibits  DNA  and 
RNA  synthesis  and  induces  apoptotic  cell  death  specifically  in  cancer  cells  by  a  mechanism  distinct 
from other DNA synthesis inhibitors. Preclinical studies have shown it to effectively inhibit the growth 
of  solid  tumors  in  the  pancreas,  lung,  colon,  renal  and  other  cancers.  Additionally,  the  FDA  has 
granted Orphan Drug Designation to RX-3117 in the treatment of pancreatic cancer. 

RX-3117  has  shown  efficacy  in  animal  models  and  human  cancer cell  lines  resistant to gemcitabine, 
which  is  one  of  the  most  widely  used  chemotherapy  drugs  on  the  market  today.  Resistance  to  the 
anti-cancer  effects  of  gemcitabine  represents  a  major  clinical  issue  in  the  treatment  of  cancer 
patients, as it has been estimated that up to 25% of cancer patients receiving one or more cycles of 
gemcitabine rapidly become resistant to its anti-cancer activity. 

In  an  exploratory  Phase  I  clinical  trial  in  cancer  patients  conducted  in  Europe  in  2012,  RX-3117 
demonstrated oral bioavailability, and no adverse events were reported over the dose range tested.  

Rexahn  initiated  a  Phase  Ib  clinical  trial  in  cancer  patients  with  solid  tumors  in  January  2014.  The 
Phase  Ib  trial  is  a multi-center,  dose-escalation  study which  evaluates  the safety,  tolerability,  dose-
limiting toxicities and maximum tolerated dose of RX-3117 in patients with solid tumors. Secondary 
endpoints  include  characterizing  the  pharmacokinetic  profile  of  RX-3117  and  evaluating  the 
preliminary anti-tumor effects of RX-3117. 

Patients enrolled in the Phase Ib trial receive RX-3117 three times a week for 3 weeks followed by 1 
week  without  treatment,  and  have  the  ability  to  continue  on  the  drug  for  up  to  eight  cycles  of 
treatment. The decision to enroll the next group of patients and escalate the dose is made after one 
cycle  of treatment,  based  on  safety  and tolerability seen  in the previous  dosing group.  Patients  are 
assessed for tumor  progression  by  CT or  MRI  scan  prior  to the start of  therapy  and  after  every two 
cycles  of  therapy.  Rexahn  expects  to  complete  enrollment  of  patients  in  the  first  half  of  2015,  with 
data available soon after. 

Archexin® 
Archexin specifically inhibits phosphorylated Akt-1 which is highly over expressed in cancer cells. The 
overall  safety  profile  of  Archexin  may  be  superior  to  existing  cytotoxic  compounds  and 
chemotherapeutic  drugs  which  affect  growth  in  both  cancer  and  non-cancer  cells.    In  two  clinical 
trials, Archexin has shown to have an excellent safety profile in cancer patients. Additionally, the FDA 
has  granted  Orphan  Drug  Designation  to  Archexin  in  the  treatment  of  five  cancers:  renal  cell, 
pancreatic, ovarian, stomach, and glioblastoma. 

In a small Phase IIa trial, Archexin demonstrated safety and preliminary signs of efficacy in advanced 
pancreatic cancer patients when used in combination with gemcitabine. Median survival for patients 
dosed with Archexin plus gemcitabine was 9.1 months as compared to historical survival data of 5.7 
months for gemcitabine alone.  

 
 
 
 
 
 
 
 
 
 
Following  consultation  with  thought  leaders  in  oncology,  Rexahn  initiated  a  Phase  IIa  trial  for 
Archexin  for  metastatic  renal  cell  carcinoma  in  January  2014.  The  combination  of  strong  scientific 
data, unmet clinical need, and the Orphan Drug Designation for renal cell carcinoma was the driving 
factor  for  choosing  this  indication.  In  addition,  resistance  to  the  anti-cancer  effects  of  mTOR 
inhibitors such as everolimus (Afinitor®), a chemotherapy drug which is used as second line therapy in 
renal cell carcinoma patients, has been attributed to an increase in Akt1 activity. Thus, treatment with 
Archexin  may  inhibit  the  growth  of  renal  cell  carcinoma  and  overcome  the  resistance  to  mTOR 
inhibitors, resulting in an increase in efficacy.  

The  on-going  Phase  IIa  trial  for  metastatic  renal  cell  carcinoma  is  a  multi-center  study  designed  to 
evaluate  the  efficacy  of  Archexin  in  combination  with  everolimus  to  treat  metastatic  renal  cell 
carcinoma  patients.    This  trial  is  being  conducted  in  two  stages.  The  first  stage  is  a  dose  ranging 
study, enrolling up to three different cohorts of three renal cell carcinoma patients to determine the 
maximum  tolerated  dose  in  combination  with  everolimus.  The  decision  to  enroll  the  next  group  of 
patients and escalate the dose is made upon completion of the first 21 day cycle of treatment. Based 
on previous clinical data, the target dose of Archexin is anticipated to be no more than 250 mg/m2 per 
day. Patient assessments include safety, pharmacokinetics, and laboratory and physical exams. Once 
the maximum tolerated dose of Archexin in combination with everolimus has been determined, thirty 
additional renal cell carcinoma patients will be enrolled. These patients will be randomized into two 
arms and receive either Archexin in combination with everolimus or everolimus alone, in a ratio of 2:1.  

The  primary  endpoint  is  the  percentage  of  patients  with  progression-free  survival  following  eight 
cycles  of  therapy.  Patients  are  scanned  by  CT  or  MRI  after  every  two  cycles  of  therapy  for  an 
assessment of tumor progression. Secondary endpoints include pharmacokinetic profile, incidence of 
adverse events, changes in clinical laboratory tests and vital signs over time, tumor response, duration 
of response, time to response, and response rate. Exploratory endpoints include blood levels of Akt1 
pathway biomarkers, tumor apoptosis biomarkers or other relevant biomarkers. 

The safety portion of this Phase IIa trial is scheduled for completion in the second half of 2015.  

II. 

Proprietary nano-drug delivery platform for FDA-approved chemo drugs:  

Rexahn’s  Nano-Polymer-Drug  Conjugate  System 
combines  FDA-approved 
chemotherapies with a proprietary polymer carrier that delivers the drug directly into the tumor 
while  bypassing  healthy  cells.  This  minimizes  the  level  of  freely-circulating  drug  in  the  body, 
resulting  in  reducing  side  effects.  It  could  also  maximize  the  amount  of  drug  in  the  tumor, 
thereby increasing its effectiveness. This technology may be of interest to other companies with 
chemotherapy  drugs,  which  can  be  made  more  effective  with  Rexahn’s  NPDCS,  presenting  a 
potential partnering opportunity that could generate revenues and non-dilutive capital. 

(NPDCS) 

RX-21101: Nano-polymer Anticancer Drug 
RX-21101  combines  the  nano-drug  delivery  system  with  docetaxel,  a  widely  used,  FDA-approved 
chemotherapy  drug.  RX-21101  may  bolster  efficacy  while  lowering  toxicity  of  docetaxel  by  specific 
tumor  targeting  and  increased  stability  in  the  body.  Potential  indications  include  breast,  ovarian, 
prostate and lung cancer.

PART I 

Item 1.    Description of Business 

Overview

We are a clinical stage biopharmaceutical company dedicated to the discovery, development and 
commercialization  of  innovative  treatments  for  cancer  and  other  medical  needs.  Our  mission  is  to 
discover  and  develop  new  medicines  for  diseases  that  plague  patients  and  have  no  effective  cures,  in 
particular high-mortality cancers. Our pipeline features one oncology candidate in Phase II clinical trials, 
two oncology candidates in Phase I clinical trials, other candidates in preclinical development, and two 
drug candidates that are not being actively developed. Our strategy is to continue building a significant 
product  pipeline  of  innovative  drug  candidates  that  we  will  commercialize  alone  or  with  partners.  We 
intend  to  initially  develop  drug  candidates  for  cancers  that  are  orphan  indications  and  then  expand  into 
more highly prevalent cancers. 

Our  three  clinical  stage  drug  candidates  in  active  development  are  Archexin®,  RX-3117  and 

SupinoxinTM (RX-5902).   

(cid:31) Archexin  is  a  potential  best-in-class,  potent  inhibitor  of  the  protein  kinase  Akt-1,  which  we 
believe plays critical roles in cancer cell proliferation, survival, angiogenesis, metastasis and drug 
resistance.    Archexin  has  received  “orphan  drug”  designation  from  the  U.S.  Food  and  Drug 
Administration  (the  “FDA”)  for  renal  cell  carcinoma  (“RCC”),  glioblastoma,  ovarian  cancer, 
stomach  cancer  and  pancreatic  cancer.    Orphan  drug  designation  provides  tax  incentives  for 
clinical research and a waiver from user fees. In addition, an orphan drug receives seven years of 
exclusivity after approval, during which the FDA generally cannot approve another product with 
the same active moiety for the same indication.    We have completed a Phase IIa clinical trial for 
Archexin  for  the  treatment  of  pancreatic  cancer,  and  in  January  2014,  we  initiated  a  Phase  IIa 
proof-of-concept clinical trial to study Archexin’s safety and efficacy in patients with metastatic 
RCC.     

(cid:31) RX-3117 is a small molecule nucleoside compound with an anti-metabolite mechanism of action, 
and we believe it has therapeutic potential in a broad range of cancers, including colon, lung and 
pancreatic cancer.    We completed an exploratory Phase I clinical study for RX-3117 in 2012 that 
demonstrated  the  oral  bioavailability  of  RX-3117  in  humans  with  no  adverse  effects  reported.   
In January 2014, we initiated a Phase Ib clinical trial to study the safety and efficacy of RX-3117 
in patients with solid tumors.    RX-3117 has received orphan drug designation from the FDA for 
pancreatic cancer.

the  FDA  for  Supinoxin.  We  initiated  a  Phase  I  clinical  in  August  2013  to  study  Supinoxin’s 
safety and efficacy in patients with solid tumors.

addition to these drug candidates, we have two clinical stage drug  candidates for  indications other  than 
cancer:  SerdaxinTM,  for  major  depressive  disorder;  and  Zoraxel,  for  sexual  dysfunction.  We  are  not 
currently allocating resources to develop these candidates and are actively seeking partners to fund their 
clinical development.

In addition to our drug development, we are also working on proprietary research technologies, 
including  our  multi-target  aimed  ligands  platform  and  nano-based  drug  delivery  systems.  Our  unique 
ligand discovery platform, The Inhibitors of Multi-Expression Signals (“TIMES”), permits us to identify 
potentially  important  targets  that  control  multiple  genes  or  signaling  events  in  cancer  cells.  Our  3-D 
Gateway  of  Ligand  Discovery  (“3-D  GOLD”)  integrates  three-dimensional  molecular  modeling  with 
databases  of  chemicals  and  proteins  and  ligand  filtering  and  generation,  which  helps  us  discover  novel 
lead compounds.    Leveraging this system, we believe that we are able to effectively develop predictive 
models, formulate and test hypotheses for optimizing efficacy and increase drug safety and bioavailability 
early  in  the  drug  discovery  process.  Our  nano-based  drug  delivery  systems,  such  as  those  used  in  the 
multiple  nanoliposomal-  and  nanopolymer-based  anticancer  drugs  that  we  are  currently  testing,  may 
increase  the  availability  of  a  drug  at  the  disease  site,  minimize  adverse  reactions  and  provide  longer 
duration of action.

Industry and Disease Markets   

Market Overview 

Our  primary  research  and  development  focus  is  on  oncology  therapeutics.    Our  strategy  is  to 
develop  innovative  drugs  that  are  potential  first-in-class  or  market-leading  compounds  for  treatment  of 
cancer. According to the Center for Disease Control and Prevention, cancer claims the lives of more than 
half a million Americans each year and is the second leading cause of death among Americans.    In 2014, 
the American Association for Cancer Research (“AACR”) estimated that the 13.3 million new cases of 
cancer diagnosed worldwide in 2010 cost $290 billion, and the 21.5 million new cancer cases anticipated 
to occur in 2030 are projected to cost $458 billion; and approximately 1.7 million new cancer cases in the 
United  States  were  estimated  in  2014  by  the  American  Cancer  Society.  In  2013,  Evaluate  Pharma 
estimated that global annual sales of cancer drugs were predicted to grow to $114 billion by 2018. 

Current Cancer Treatments 

Traditional cancer treatments involve surgery, radiation therapy and chemotherapy.    Surgery is 
widely used to treat cancer, but may result in related or significant complications and may be ineffective 
if metastasis has occurred.    Radiation therapy, or radiotherapy, can be highly effective in treating certain 
types of cancer.    In radiation therapy, ionizing radiation deposits energy that injures or destroys cells in 
the area being treated by damaging their genetic material, making it impossible for these cells to continue 
to grow.    Although radiation damages both cancer cells and normal cells, the normal cells are generally 
able  to  repair  themselves  and  function  properly.    Chemotherapy  involves  the  use  of  cytotoxic  cancer 

2

 
 
 
drugs to destroy cancer cells by interfering with various stages of the cell division process.    For certain 
cancers  and  in  certain  patients,  these  drugs  have  limited  efficacy  and  debilitating  adverse  side  effects. 
Cytotoxic  cancer  drugs  may  also  result  in  the  development  of  multiple  drug,  or  multi-drug,  resistance, 
which  is  a  condition  that  results  when  certain  tumor  cells  that  have  survived  treatment  with  cytotoxic 
drugs are no longer susceptible to treatment by those and other drugs. 

Unmet Needs in Cancer   

Despite  significant  advances  in  cancer  research  and  treatments,  many unmet needs still remain 

including:

(cid:31)

Long-term  management  of  cancers:    Surgery,  radiation  therapy  or  chemotherapy  may  not 
result  in  long-term  remission,  although  surgery  and  radiation  therapies  are  considered 
effective methods for some cancers.    There is a need for more effective drugs and adjuvant 
therapies to treat relapsed and refractory cancers. 

(cid:31) Multi-drug  resistance:    Multi-drug  resistance  is  a  major  obstacle  to  effectively  treating 

various cancers with chemotherapy. 

(cid:31) Debilitating  toxicity  by  chemotherapy: Chemotherapy  as  a  mainstay  of  cancer  treatment 

induces severe adverse reactions and toxicities, affecting quality of life or life itself. 

Market Opportunity 

There  are  several  factors  favorable  for  commercializing  new  cancer  drugs  that  may  be 

first-in-class or market leaders, including: 

(cid:31) Expedited Regulatory or Commercialization Pathways.    Drugs for life-threatening diseases such 
as  cancer  are  often  candidates  for  fast  track  designation,  breakthrough  therapy  designation, 
priority review and accelerated approval, each of which can lead to approval sooner than would 
otherwise be the case. 

(cid:31) Favorable  Environment  for  Formulary  Access  and  Reimbursement.    We  believe  that  cancer 
drugs  with  proven  efficacy  would  gain  rapid  market  uptake,  formulary  listing  and  third-party 
payor reimbursement.    Drugs with orphan designations are generally reimbursed by third-party 
payors because there are few, if any, alternatives.     

(cid:31) Focus  on  Specialty  Markets.    The  marketing  of  new  drugs  to  specialty  physicians  can  be 
accomplished  with  a  specialty  sales  force  that  requires  fewer  personnel  and  lower  related  costs 
than a typical sales force that markets widely to primary care physicians and general practitioners. 

Our Strategy   

Our strategy is to continue building a significant product pipeline of innovative drug candidates 

that we will commercialize alone or with partners.    This strategy has several key components. 

Develop Innovative Therapeutics with the Potential to be First-in-Class or Market Leaders 

We  plan  to  focus  our  research  and  development  pipeline  on  potential  first-in-class  or 
market-leading  compounds  for  the  treatment  of  cancer.    By  expanding  the  breadth  and  depth  of  our 

3

 
 
oncology pipeline, we aim to develop an industry-leading oncology therapeutics franchise.    Our pipeline 
spans  several  major  classes  of  cancer  drugs,  including  molecular  targeted  therapies,  signal  transduction 
and  multi-kinase  inhibitors,  nano-medicines  for  target  delivery  of  compounds  and  small  molecule 
cytotoxic  compounds.  Differentiated  target  product  profiles  and  proprietary  discovery  and  research 
technology platforms further support these strategic efforts.     

Clinically Develop Drug Candidates as Orphan Drugs 

We intend to initially develop drug candidates for cancers that are orphan indications. Under the 
Orphan Drug Act, the FDA may grant orphan drug designation to new drugs that treat diseases affecting 
less than 200,000 patients.    Incentives associated with orphan drug designation include tax incentives for 
research  and  development  and  an  exemption  from  user  fees.    Although  the  standards  for  orphan  drug 
approval  are  not  different  than  for  non-orphan  products,  the  path  to  approval  may  be  faster  because 
clinical trials may be smaller due to the smaller patient population. Additionally, drugs intended to treat 
rare  diseases  or  conditions  may  qualify  for  fast  track  designation,  breakthrough  therapy  designation, 
accelerated approval or priority review, all of which can speed the approval process.    Further, a drug that 
is approved  for its orphan-designated indication receives seven years of orphan drug exclusivity during 
which the FDA generally may not approve any other application for a product containing the same active 
moiety and proposed for the same indication.    We plan to develop drug candidates for cancers that are 
orphan indications in order to reduce the time-to-market and to take advantage of the benefits of orphan 
drug  designation  during  development  and  the  exclusivity  available  under  the  Orphan  Drug  Act  for 
approved products. 

Target Signal Transduction Molecules with Multiple Drug Candidates 

We plan to expand our research and development pipeline to introduce new signal inhibitor drugs 
into clinical trials in the future.    By identifying and characterizing the genes and proteins that control the 
signaling  pathways  and  gene  expression  of  cancer  cells,  we  seek  to  develop  DNA/RNA-based  and 
small-molecule  drugs  to  treat  a  broad  range  of  diseases  caused  by  abnormal  expression  or  functions  of 
those genes and proteins.     

Establish Partnerships with Large Pharmaceutical Companies 

We seek to establish strategic alliances and partnerships with large pharmaceutical companies for 

the development of our drug candidates. 

In-License Unique Technology 

We continually review opportunities to in-license and advance compounds in oncology that have 

value creating potential and will strengthen our clinical development pipeline.   

Capitalize on Our Management Team’s Expertise for Drug Development 

Our management team possesses clinical development experience in oncology and several other 
therapeutic  areas  that  facilitates  strategic  approaches  to  and  competitive  advantages  in,  the  design,  risk 
assessment  and  implementation  of  drug  development  programs.  Our  management  team  also  has  prior 
experience in pharmaceutical alliances, product launches and marketing.

Our Pipeline Drug Candidates 

Clinical Stage Pipeline 

Archexin: Potential Best-in-class Anticancer Akt-1 Inhibitor 

Archexin  is  a  potential  best-in-class,  potent  inhibitor  of  the  protein  kinase  Akt-1,  which  we 
believe  plays  critical  roles  in  cancer  cell  proliferation,  survival,  angiogenesis,  metastasis  and  drug 
resistance.  Archexin  has  received  “orphan  drug”  designation  from  the  FDA  for  RCC,  glioblastoma, 
ovarian cancer, stomach cancer and pancreatic cancer. We believe Archexin is differentiated from other 
Akt-1 inhibitors by its ability to inhibit both activated and inactivated forms of Akt-1 and in that it is not 
expected to lead to drug resistance observed with other protein kinase inhibitors.    Other targeted drugs 
may  only  inhibit  inactivated  Akt-1  and  may  also  cause  drug  resistance.    Akt-1  is  over-activated  in 
patients  with  many  cancers,  including  breast,  colorectal,  gastric,  pancreatic,  prostate  and  melanoma 
cancers.    Akt-1  activity  may  be  inhibited  by  signaling  molecules  upstream  of  Akt-1  in  cancer  cells 
through the use of vascular endothelial growth factor and epidermal growth factor receptor inhibitors, but 
this treatment only affects indirectly the activity of native Akt-1.    Because signal transmission for cancer 
progression  and  resistance  occurs  when  Akt-1  is  activated,  we  believe  it  is  also  important  to  inhibit 
activated Akt-1.    We believe that Archexin inhibits both activated and native Akt-1. 

Archexin is an antisense oligonucleotide compound that is complementary to Akt-1 mRNA and 

highly  selective  for  inhibiting  mRNA  expression  and  leading  to  reduced  production  of  Akt-1  protein.   
Archexin has preliminarily demonstrated safety, tolerability and minimal side effects in a Phase I study in 
patients  with  advanced  cancers,  where  Grade  3  fatigue  was  the  only  dose-limiting  toxicity  and  no 
significant hematological abnormalities were observed. The main objectives of the Phase I study were to 
determine maximum tolerated dose, dose limiting toxicity and pharmacokinetic parameters for Archexin 
monotherapy.    The Archexin Phase I study design was an open label, single arm ascending dose, safety 
and tolerability study.     

In August 2012, we announced top-line results of an open label 2-stage Phase IIa clinical trial for 
Archexin that was designed to assess the safety and efficacy of Archexin in combination with gemcitabine. 
Gemcitabine is used to treat pancreatic, breast, ovarian, and lung cancers, and may be used for other cancers 
as well.    Gemcitabine is a member of a group of chemotherapy drugs known as anti-metabolites, which 
prevent cells from making DNA and RNA, which stops cell growth and causes cells to die.    Stage 1 was 
the dose-finding portion of the study, and Stage 2 was the dose-expansion portion of the study using the 
dose identified in Stage 1 administered together with gemcitabine.    The study enrolled 31 subjects aged 18 
to  65  with  metastatic  pancreatic  cancer  at  nine  centers  in  the  United  States  and  India.    The  primary 
endpoint  was  overall  survival  following  four  cycles  of  therapy  with  a  six  month  follow-up.    For  those 
evaluable patients, the study demonstrated that treatment with Archexin in combination with gemcitabine 
provided a median survival rate of 9.1 months compared to the historical survival data of 5.65 months for 
standard  single  agent  gemcitabine  therapy.      The  most  frequently  reported  adverse  events  were 
constipation, nausea, abdominal pain and pyrexia, regardless of relatedness.     

We initiated a Phase IIa clinical proof-of-concept clinical trial of Archexin in January 2014 to study 
its  safety  and  efficacy  in  patients  with  metastatic  RCC.  In  the  trial,  Archexin  will  be  administered  in 
combination  with  Afinitor®  (everolimus)  tablets.    The  trial  will  be  conducted  in  two  stages.    The  first 
stage will be the dose ranging portion of the study, with up to three dose groups with three RCC patients 
each, to determine its maximal tolerated dose (“MTD”) in combination with everolimus.    Once the MTD 
has  been  determined,  thirty  RCC  patients  will  be  randomized  to  either  Archexin  in  combination  with 
everolimus or everolimus alone, in a ratio of 2:1.    We plan to complete the initial safety component of this 
study in the second half of 2015.     

5

 
The Company has been issued a U.S. patent for Archexin that covers composition of matter and 
broad  claims  for  the  nucleotide  sequences  of  the  antisense  compounds  that  target  and  inhibit  the 
expression  of  Akt-1  in  human  tissues  or  cells,  and  the  method  of  using  the  compounds  to  induce 
cytotoxicity in cancer cells. 

RX-3117: Small Molecule Nucleoside 

RX-3117 is a small molecule nucleoside compound with an anti-metabolite mechanism of action, 
and  we  believe  it  has therapeutic  potential  in  a  broad  range  of  cancers,  including  colon,  lung  and 
pancreatic  cancer.    We  completed  an  exploratory  Phase  I  clinical  study  of  RX-3117  in  2012  that 
demonstrated the oral bioavailability of RX-3117 in humans with no adverse effects reported in the study.     

In  January  2014,  we  initiated  a  Phase  Ib  clinical  trial  to  study  the  safety,  tolerability, 
dose-limiting toxicities and MTD of RX-3117 in patients with solid tumors.    Secondary endpoints will 
include characterizing the pharmacokinetic profile of RX-3117 and evaluating the preliminary anti-tumor 
effects of RX-3117.    Patient enrollment has been completed in eight dose groups (30mg, 60mg, 100mg, 
150mg, 200mg, 500mg, 1,000mg and 1,500mg) and the MTD of RX-3117 has not yet been achieved.    We 
expect to complete patient enrollment in the first half of 2015.         

Supinoxin: Potential First-in-Class p68 RNA Inhibitor 

Supinoxin is a potential first-in-class small molecule that inhibits the phosphorylation of p68, a 
protein that we believe plays a key role in cancer growth, progression and metastasis. Phosphorylated p68, 
which  is  highly  expressed  in  cancer  cells,  but  not  in  normal  cells,  results  in  up-regulation  of 
cancer-related  genes  and  a  subsequent  proliferation  or  tumor  growth  of  cancer  cells.    Supinoxin 
selectively blocks phosphorylated p68, thereby decreasing the proliferation or growth of cancer cells.    In 
pre-clinical tissue culture models and in-vivo xenograft  models,  Supinoxin has demonstrated synergism 
with cytotoxic agents and activity against drug resistant cancer cells.    In July 2012, we submitted an IND 
application to the FDA for Supinoxin.   

We  initiated  a  Phase  I  clinical  trial  in  August  2013  to  study  Supinoxin’s  safety  and  efficacy  in 
patients with solid tumors.    Patients in seven dose groups (25mg, 50mg, 100mg, 150mg, 225mg, 300mg 
and 425mg) have been enrolled and the MTD of Supinoxin has not yet been reached.    Depending on the 
number of dose groups needed to determine the MTD, we expect to complete this trial in the first half of 
2015.    Based  on  the  progress  of  the  Supinoxin  clinical  development  program  and  the  level  of  interest 
expressed  from  a  number  of  oncology-focused  pharmaceutical  companies,  Rexahn  is  continuing  its 
discussions with multiple companies to explore collaborative business structures in an effort to maximize 
the potential upside value of the program. 

Non-Oncology Candidates 

We  have  two  candidates  for  indications  other  than  oncology:  Serdaxin,  for  major  depressive 
disorder,  and  Zoraxel,  for  sexual  dysfunction.  In  January,  2013,  we  determined  to  cease  allocating 
resources to develop these candidates. We are seeking partners to fund their clinical development. 

Pre-Clinical Pipeline 

Archexin-Nano:    Nanoliposomal anticancer Akt-1 inhibitor 

6

 
Archexin  is  a  potential  first-in-class,  potent  inhibitor  of  Akt-1,  and  Archexin-Nano  is  a 
nanoliposomal product of Archexin with high incorporation efficiency and good stability. We believe that 
Archexin-Nano  may  provide  significant  clinical  benefits  including  targeted  higher  cellular  intake, 
extended circulation time, reduced drug toxicity, and improved efficacy. 

RX-21101:    Nano-polymer Anticancer Drug 

RX-21101 is an investigational anticancer nano-polymer drug that we believe can mitigate some 
of  the  limitations  of  cytotoxic  compounds,  such  as  poor  solubility  and  severe  adverse  reactions. 
Conjugating  water-soluble  and  non-toxic  HPMA  to  conventional  anticancer  compounds  may  bolster 
efficacy while lowering toxicity by specific tumor targeting and increased stability in the body.   

Research and Development Process

We  have  engaged  third-party  contract  research  organizations  and  other  investigators  and 
collaborators, such as universities and medical institutions, to conduct our pre-clinical studies, toxicology 
studies and clinical trials. Engaging third-party contract research organizations is typical practice in our 
industry. However, relying on such organizations means that the clinical trials and other studies described 
above are being conducted at external locations and that the completion of these trials and studies is not 
within our direct control. Trials and studies may be delayed due to circumstances outside our control, and 
such delays may result in additional expenses for us. 

Competition 

We  compete  against  fully  integrated  pharmaceutical  companies  and  smaller  companies  that  are 
collaborating  with  larger  pharmaceutical  companies,  as  well  as  academic  institutions,  government 
agencies and other public and private research organizations. Many of these competitors, either alone or 
together  with  their  collaborative  partners,  operate  larger  research  and  development  programs  or  have 
substantially greater financial resources than we do, as well as more experience in: 

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

developing drugs; 

undertaking pre-clinical testing and human clinical trials; 

obtaining FDA and other regulatory approvals of drugs; 

formulating and manufacturing drugs; and 

launching, marketing and selling drugs. 

Large  pharmaceutical  companies  currently  sell  both  generic  and  proprietary  compounds  for  the 
treatment  of  cancer.  In  addition,  companies  pursuing  different  but  related  fields  represent  substantial 
competition. Many of these organizations have substantially greater capital resources, larger research and 
development staff and facilities, longer drug development history in obtaining regulatory approvals and 
greater manufacturing and marketing capabilities than we do. These organizations also compete with us to 
attract qualified personnel, parties for acquisitions, joint ventures or other collaborations. 

We are aware of products under development by our competitors that target the same indications 
as our clinical stage drug candidates. If  approved,  Archexin could compete with other Akt-1 inhibitors, 
such  as  MK-2206  and  GSK-2141795,  which  are  under  development  by  Merck  &  Company,  Inc.  and 

7

 
 
 
GlaxoSmithKline,  respectively.    If  approved,  RX-3117  could  compete  with  other  compounds  with  an 
anti-metabolite  mechanism  of  action  in  cancers,  such  as  Sapacitabine  which  is  under  development  by 
Cyclacel.    We  are  not  currently  aware  of  known  inhibitors  of  phosphorylated  p68  that  would  compete 
with  Supinoxin  if  Supinoxin  were  approved.  Our  competitors  may  succeed  in  developing  products  that 
are more safe and/or effective than ours, which could render our product candidates less competitive prior 
to recovery by us of expenses incurred with respect to their development. 

Government Regulation   

Regulation by governmental authorities in the United States and in other countries is a significant 
consideration in our product development, manufacturing and marketing strategies.    We expect that all 
of our drug candidates will require regulatory approval by the FDA and by similar regulatory authorities 
in foreign countries prior to commercialization and will be subjected to rigorous pre-clinical, clinical, and 
post-approval  testing  to  demonstrate  safety  and  effectiveness,  as  well  as  other  significant  regulatory 
requirements  and  restrictions  in  each  jurisdiction  in  which  we  would  seek  to  market  our  products.   
U.S. federal  regulations  control  the  testing,  development,  manufacture,  quality  control,  safety, 
effectiveness,  approval,  storage,  labeling,  record  keeping,  reporting,  distribution,  import,  export  and 
marketing of all biopharmaceutical products intended for therapeutic purposes.    We believe that we and 
the  third  parties  that  work  with  us  are  in  compliance  in  all  material  respects  with  currently  applicable 
rules and regulations.    Those rules and regulations are subject to change, however, and in any event, a 
failure  to  comply  could  have  a  material  negative  impact  on  our  ability  to  successfully  develop  and 
commercialize our products, and therefore on our financial performance. 

Obtaining  governmental  approvals  and  maintaining  ongoing  compliance  with  applicable 
regulations  are  expected  to  require  the  expenditure  of  significant  financial  and  human  resources  not 
currently  at  our  disposal.    We  plan  to  fulfill  our  short-term  needs  through  consulting  agreements  and 
joint  ventures  with  academic  or  corporate  partners  while  developing  our  own  internal  infrastructure  for 
long-term corporate growth. 

Development and Approval

The process to approve biopharmaceutical compounds for therapeutic use for commercialization 
in the United States and many other countries is lengthy, complex and expensive, and the outcome is far 
from certain.    Although foreign requirements for conducting clinical trials and obtaining approval may 
be different than in the United States, they often are equally rigorous and the outcome cannot be predicted 
with confidence. A key component of any submission for approval in any jurisdiction is pre-clinical and 
clinical data demonstrating the product’s safety and effectiveness.     

Pre-clinical Testing.    Before testing any compound in humans in the United States, a company 
must  develop  pre-clinical  data,  generally  including  laboratory  evaluation  of  product  chemistry  and 
formulation, as well as toxicological and pharmacological studies in animal species to assess safety and 
quality.    Animal  studies  must  be  conducted  in  compliance  with  the  FDA’s  Good  Laboratory  Practice 
(“GLP”) regulations and the Animal Welfare Act, which is enforced by the Department of Agriculture. 

IND  Application.    In  the  United  States,  FDA  regulations  require  that  the  person  or  entity 
sponsoring or conducting a clinical study for the purpose of investigating a potential drug product’s safety 
and effectiveness submit to the FDA an IND application, which contains pre-clinical testing results and 
provides a basis for the FDA to conclude that there is an adequate basis for testing the drug in humans.   
If  the  FDA  does  not  object  to  the  IND  application  within  30  days  of  submission,  the  clinical  testing 
proposed in the IND may begin.    Even after the IND has gone into effect and clinical testing has begun, 

8

 
the  FDA  may  put  the  clinical  trials  on  “clinical  hold,”  suspending  (or  in  some  cases,  ending)  them 
because of safety concerns or for other reasons.     

Clinical  Trials.    Clinical  trials  involve  administering  a  drug  to  human  volunteers  or  patients, 
under  the  supervision  of  a  qualified  clinical  investigator.    Clinical  trials  are  subject  to  extensive 
regulation.    In  the  United  States,  this  includes  compliance  with  the  FDA’s  bioresearch  monitoring 
regulations and Good Clinical Practice (“GCP”) requirements, which establish standards for conducting, 
recording data from, and reporting the results of, clinical trials, with the goal of assuring that the data and 
results are credible and accurate and that study participants’ rights, safety and well-being are protected.   
Each  clinical  trial  must  be  conducted  under  a  protocol  that  details  the  study  objectives,  parameters  for 
monitoring safety and the efficacy criteria, if any, to be evaluated.    The protocol is submitted to the FDA 
as  part  of  the  IND  and  reviewed  by  the  agency  before  the  study  is  commenced.    Additionally,  each 
clinical  trial  must  be  reviewed,  approved  and  conducted  under  the  auspices  of  an  Institutional  Review 
Board (“IRB”) at the institution at which the trial is being conducted.    The sponsor of a clinical trial, the 
investigators  and  IRBs  each  must  comply  with  requirements  and  restrictions  that  govern  obtaining 
informed  consent  from  each  study  subject,  complying  with  the  protocol  and  investigational  plan, 
adequately monitoring the clinical trial, and timely reporting adverse events.    Foreign studies conducted 
under  an  IND  must  meet  the  same  requirements  applicable  to  studies  conducted  in  the  United  States.   
However, if a foreign study is not conducted under an IND, the data may still be submitted to the FDA in 
support of a product application, if the study was conducted in accordance with GCP and the FDA is able 
to validate the data. 

Sponsors  of  clinical  trials  are  required  to  make  public  certain  information  about  active  clinical 
trials  and  trial  results  by  posting  the  information  on  government  or  independent  websites,  such  as 
http://clinicaltrials.gov.    Clinical testing is typically performed in three phases. 

In Phase I, the drug is administered to a small number of human subjects to confirm its safety and 
to  develop  detailed  profiles  of  its  pharmacological  and  pharmacokinetic  actions  (i.e.,  absorption, 
distribution,  metabolism,  and  excretion).    Although  Phase  I  trials  typically  are  conducted  in  healthy 
human subjects, in some instances (including, for example, with some cancer therapies) the study subjects 
are patients with the targeted disease or condition. 

In Phase II, the drug is administered to groups of patients (usually no more than several hundred) 
to develop initial data regarding efficacy against the targeted disease and determine the requisite dose and 
dose intervals, and generate additional information regarding the drug’s safety.    In a typical development 
program, additional animal toxicology studies precede this phase.    In some cases, the trial can be split 
into Phase IIa and IIb studies in order to test smaller subject pools.    Some Phase I clinical studies may 
proceed in parallel with some Phase II studies.   

In Phase III, the drug is administered to a larger group of patients (usually from several hundred 
to several thousand or more).    Phase III studies also can include patients with concomitant diseases and 
medications.    Larger  patient  populations  are  evaluated  in  Phase  III  at  multiple  study  sites  and  many 
clinical  trial  programs  or  registration  studies  are  conducted  concurrently  for  the  sake  of  time  and 
efficiency.    The  extensive  clinical  testing  is  intended  to  obtain  additional  information  about  product 
safety and effectiveness necessary to evaluate the drug’s overall risk-benefit profile and to provide a basis 
for  physician  labeling.    Phase  III  data  often  form  the  core  basis  on  which  the  FDA  evaluates  the 
product’s safety and effectiveness when considering an application to market the drug. 

The study sponsor, the FDA or an IRB may suspend or terminate a clinical trial at any time on 
various  grounds,  including  a  determination  that  study  subjects  are  being  exposed  to  an  unacceptable 
health  risk.    Additionally,  success  in  early-stage  clinical  trials  does  not  assure  success  in  later-stage 

9

 
 
clinical  trials,  and  data  from  clinical  trials  are  not  always  conclusive  and  may  be  subject  to  alternative 
interpretations that could delay, limit or prevent approval. 

NDA Submission and Review.    After completing the clinical studies, a sponsor seeking approval 
to market a drug in the United States submits to the FDA a New Drug Application (“NDA”).    The NDA 
is  a  comprehensive,  multi-volume  application  intended  to  demonstrate  the  product’s  safety  and 
effectiveness and includes, among other things, pre-clinical and clinical data, information about the drug’s 
composition,  the  sponsor’s  plans  for  manufacturing  and  packaging  and  proposed  labeling.    When  an 
NDA is submitted, the FDA  makes an initial  determination as to whether the  application is sufficiently 
complete to be accepted for review.    If the application is not, the FDA may refuse to accept the NDA for 
filing  and  request  additional  information.    A  refusal  to  file,  which  requires  resubmission  of  the  NDA 
with the requested additional information, delays review of the application.   

FDA performance goals regarding the timeliness of NDA review generally provide for action on 
an  NDA  within  12  months  of  its  submission.    That  deadline  can  be  extended  under  certain 
circumstances, including by FDA requests for additional information.    The targeted action date can also 
be  shortened  to  eight  months  after  submission,  for  products  that  are  intended  to  treat  serious  or 
life-threatening conditions and demonstrate the potential to address unmet medical needs.    Additionally, 
the  FDA  has  programs  for  enhanced  communication  and  consultation  and  other  steps  to  expedite 
submission and consideration of such products.    We anticipate, but cannot ensure, that our products will 
qualify for such programs. 

If  it  concludes  that  an  NDA  does  not  meet  the  regulatory  standards  for  approval,  the  FDA 
typically issues a Complete Response letter, which communicates the reasons for the agency’s decision 
not to approve the application and may request additional information, including additional clinical data.   
An  NDA  may  be  resubmitted  with  the  deficiencies  addressed,  but  that  does  not  guarantee  approval.   
Data from clinical trials are not always conclusive, and the FDA’s interpretation of data may differ from 
the  sponsor’s.    Obtaining  approval  can  take  years,  requires  substantial  resources  and  depends  on  a 
number  of  factors,  including  the  severity  of  the  targeted  disease  or  condition,  the  availability  of 
alternative  treatments,  and  the  risks  and  benefits  demonstrated  in  clinical  trials.    Additionally,  as  a 
condition of approval, the FDA may impose restrictions that could affect the commercial prospects of a 
product, such as a Risk Evaluation and Mitigation Strategy (“REMS”), and could require post-approval 
commitments  to  conduct  additional  studies  or  conduct  surveillance  programs  to  monitor  the  drug’s 
effects.     

Moreover, once a product is approved, information about its safety or effectiveness from actual 
use  can  limit  or  prevent  successful  commercialization,  either  because  of  regulatory  action  or  market 
forces.    Post-approval  modifications  to  a  drug  product,  such  as  changes  in  indications,  labeling  or 
manufacturing processes or facilities, may require development and submission of additional information 
or data in a new or supplemental NDA, which would also require FDA approval. 

One  of  our  drug  candidates,  Archexin  is  an  antisense  oligonucleotide  (“ASO”)  compound.  To 
date, the FDA has not approved any NDAs for any ASO compounds for cancer treatment; however, the 
FDA  has  approved  the  ASO  compounds  fomivirsen  (marketed  as  Vitravene®)  as  a  treatment  for 
cytomegalovirus  retinitis,  and  mipomersen  sodium  (marketed  as  Kynamro®),  as  a  treatment  for 
homozygous familial hypercholesterolemia. In addition, Archexin and Archexin-nano are in a drug class 
known as Akt-1 inhibitors, and drugs from this class has not been approved by the FDA to date, and we 
have not submitted an NDA for any of these drug candidates.   

Exclusivity  and  Patent  Protection.    In  the  United  States  and  elsewhere,  certain  regulatory 
exclusivities  and  patent  rights  can  provide  an  approved  drug  product  with  protection  from  certain 

10 

 
competitors’  products  for  a  period  of  time  and  within  certain  scopes.    In  the  United  States,  those 
protections include exclusivity under the Orphan Drug Act, which is available for drugs intended to treat 
rare  diseases  or  conditions,  which  generally  are  diseases  or  conditions  that  affect  fewer  than 
200,000 persons  in  the  United  States.    If  a  sponsor  demonstrates  that  a  drug  is  intended  to  treat  a  rare 
disease or condition, the FDA grants orphan drug designation to the product for that use.    A product that 
has received orphan drug designation is eligible for research and development tax credits and is exempt 
from user fees.    Additionally, a drug that is approved for its orphan-designated indication receives seven 
years  of  orphan  drug  exclusivity.    During  that  period,  FDA  generally  may  not  approve  any  other 
application for a product containing the same active moiety and proposed for the same indication.    There 
are  exceptions,  however,  most  notably  when  the  later  product  is  shown  to  be  clinically  superior  to  the 
product with exclusivity.    Products that qualify for orphan designation may also qualify for other FDA 
programs that are intended to expedite the development and approval process and, as a practical matter, 
clinical  trials  for  orphan  products  may  be  smaller,  simply  because  of  the  smaller  patient  population.   
Nonetheless, the same approval standards apply to orphan-designated products as for other drugs.     

Archexin  has  received  orphan  drug  designation  from  the  FDA  for  RCC,  glioblastoma,  ovarian 
cancer,  stomach  cancer  and  pancreatic  cancer.    RX-3117  received  orphan  drug  designation  for 
pancreatic cancer in September 2014. 

Post-Approval Regulation 

Once approved, products are subject to continuing extensive regulation by the FDA.    If ongoing 
regulatory requirements are not met, or if safety problems occur after a product reaches market, the FDA 
may take actions to change the conditions under which the product is marketed, including suspending or 
even  withdrawing  approval.    In  addition  to  FDA  regulation,  the  healthcare  industry,  and  therefore  our 
business, is also subject to extensive federal, state, local and foreign regulation.     

Good  Manufacturing  Practices.    Companies  engaged  in  manufacturing  drug  products  or  their 
components must comply with applicable current Good Manufacturing Practice (“cGMP”) requirements, 
which  include  requirements  regarding  organization  and  training  of  personnel,  building  and  facilities, 
equipment, control of components and drug product containers, closures, production and process controls, 
packaging  and  labeling  controls,  holding  and  distribution,  laboratory  controls  and  records  and  reports.   
The  FDA  inspects  equipment,  facilities  and  manufacturing  processes  before  approval  and  conducts 
periodic  re-inspections  after  approval.    Failure  to  comply  with  applicable  cGMP  requirements  or  the 
conditions  of  the  product’s  approval  may  lead  the  FDA  to  take  administrative  enforcement  action.   
Although  we  periodically  monitor  the  FDA  compliance  of  the  third  parties  on  which  we  rely  for 
manufacturing  our  drug  products,  we  cannot  be  certain  that  our  present  or  future  third-party 
manufacturers will consistently comply with cGMP or other applicable FDA regulatory requirements. 

Sales and Marketing.    Once a product is approved, its advertising, promotion and marketing will 
be  subject  to  close  regulation,  including  with  regard  to  promotion  to  healthcare  practitioners, 
direct-to-consumer advertising, communications regarding unapproved uses, industry-sponsored scientific 
and  educational  activities  and  promotional  activities  involving  the  internet.  In  addition  to  FDA 
restrictions  on  marketing  of  pharmaceutical  products, state  and  federal  fraud  and  abuse  laws  have  been 
applied  to  restrict  certain  marketing  practices  in  the  pharmaceutical  industry  in  recent  years.    Some  of 
the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and 
their provisions are open to a variety of interpretations. In addition, these laws and their interpretations are 
subject to change.   

Fraud and Abuse Laws.    The restrictions under applicable federal and state health care fraud and 

abuse laws and regulations that may affect our ability to operate include: 

11 

 
 
     
(cid:31) The  federal  Anti-Kickback  Law,  which  prohibits,  among  other  things,  knowingly  or 
willingly offering, paying, soliciting or receiving remuneration, directly or indirectly, in 
cash or in kind, to induce or reward the purchasing, leasing, ordering or arranging for or 
recommending the purchase, lease or order of any health care items or service for which 
payment  may  be  made,  in  whole  or  in  part,  by  federal  healthcare  programs  such  as 
Medicare  and  Medicaid.  This  statute  has  been  interpreted  to  apply  to  arrangements 
between  pharmaceutical  companies  on  one  hand  and  prescribers,  purchasers  and 
formulary managers on the other. Further, the Patient Protection and Affordable Care Act, 
as amended by the Health Care and Education Reconciliation Act of 2010, together the 
Affordable Care Act, clarified among other things that liability may be established under 
the federal Anti-Kickback law without proving actual knowledge of the statute or specific 
intent to violate it. In addition, the Affordable Care Act amended the Social Security Act 
to  provide  that  the  government  may  assert  that  a  claim  including  items  or  services 
resulting  from  a  violation  of  the  federal  Anti-Kickback  Law  constitutes  a  false  or 
fraudulent claim for purposes of the federal civil False Claims Act. Although there are a 
number of statutory exemptions and regulatory safe harbors to the federal Anti-Kickback 
Law protecting certain common business arrangements and activities from prosecution or 
regulatory sanctions, the exemptions and safe harbors are drawn narrowly, and practices 
that do not fit squarely within an exemption or safe harbor may be subject to scrutiny; 

(cid:31) The  federal  civil  False  Claims  Act,  which  prohibits, among  other  things,  individuals  or 
entities from knowingly presenting, or causing to be presented, a false or fraudulent claim 
for payment of government funds or knowingly making, using or causing to be made or 
used,  a  false  record  or  statement  material  to  an  obligation  to  pay  money  to  the 
government or knowingly concealing or knowingly and improperly avoiding, decreasing 
or  concealing  an  obligation  to  pay  money  to  the  federal  government.  Many 
pharmaceutical and other healthcare companies have been investigated and have reached 
substantial financial settlements with the federal government under the civil False Claims 
Act  for  a  variety  of  alleged  improper  marketing  activities,  including:  providing  free 
product to customers with the expectation that the customers would bill federal programs 
for  the  product;  providing  consulting  fees,  grants,  free  travel  and  other  benefits  to 
physicians  to  induce  them  to  prescribe  the  company’s  products;  and  inflating  prices 
reported  to  private  price  publication  services,  which  are  used  to  set  drug  payment  rates 
under government healthcare programs. In addition, in recent years the government has 
pursued civil False Claims Act cases against a number of pharmaceutical companies for 
causing  false  claims  to  be  submitted  as  a  result  of  the  marketing  of  their  products  for 
unapproved,  and  thus  non-reimbursable,  uses.  Pharmaceutical  and  other  healthcare 
companies  also  are  subject  to  other  federal  false  claim  laws,  including,  among  others, 
federal  criminal  healthcare  fraud  and  false  statement  statutes 
to 
non-government health benefit programs; 

that  extend 

(cid:31) Analogous state laws and regulations, such as state anti-kickback and false claims laws, 
may apply to items or services reimbursed under Medicaid and other state programs or, in 
several states, apply regardless of the payor. Some state laws also require pharmaceutical 
companies to report expenses relating to the marketing and promotion of pharmaceutical 
products  and  to  report  gifts  and  payments  to  certain  healthcare  providers  in  the  states. 
Other states prohibit providing meals to prescribers or other marketing related activities. 
In  addition,  California,  Connecticut,  Nevada  and  Massachusetts  require  pharmaceutical 
companies to implement compliance programs or marketing codes of conduct.   

12 

 
(cid:31) The federal Physician Payment Sunshine Act, being implemented as the Open Payments 
Program, requires certain pharmaceutical manufacturers to engage in extensive tracking 
of  payments  and  other  transfers  of  value  to  physicians  and  teaching  hospitals,  and  to 
submit such data to the Centers for Medicare and Medicaid Studies (“CMS”), which will 
then  make  all  of  this  data  publicly  available  on  the  CMS  website.  Pharmaceutical 
manufacturers with products for which payment is available under Medicare, Medicaid or 
the  State  Children’s  Health  Insurance  Program  are  required  to  have  started  tracking 
reportable payments on August 1, 2013 and must submit a report to CMS on or before the 
90th  day  of  each  calendar  year  disclosing  reportable  payments  made  in  the  previous 
calendar  year.    Failure  to  comply  with  the  reporting  obligations  may  result  in  civil 
monetary penalties; 

(cid:31) The federal Foreign Corrupt Practices Act of 1997 and other similar anti-bribery laws in 
other jurisdictions generally prohibit companies and their intermediaries from providing 
money or anything of value to officials of foreign governments, foreign political parties, 
or  international  organizations  with  the  intent  to  obtain  or  retain  business  or  seek  a 
business advantage.    Recently, there has been a substantial increase in anti-bribery law 
enforcement activity by U.S. regulators, with more frequent and aggressive investigations 
and enforcement proceedings by both the Department of Justice and the U.S. Securities 
and  Exchange  Commission  (“SEC”).    Violations  of  United  States  or  foreign  laws  or 
regulations  could  result  in  the  imposition  of  substantial  fines,  interruptions  of  business, 
loss  of  supplier,  vendor  or  other  third-party  relationships,  termination  of  necessary 
licenses and permits and other legal or equitable sanctions. Other internal or government 
investigations  or  legal  or  regulatory  proceedings,  including  lawsuits  brought  by  private 
litigants, may also follow as a consequence. 

Violations of any of the laws described above or any other governmental regulations are punishable by 
significant  civil,  criminal  and  administrative  penalties,  damages,  fines  and  exclusion  from 
government-funded  healthcare  programs,  such  as  Medicare  and  Medicaid.    Although  compliance 
programs  can  mitigate  the  risk  of  investigation  and  prosecution  for  violations  of  these  laws,  the  risks 
cannot  be  entirely  eliminated.    Moreover,  achieving and  sustaining  compliance  with  applicable  federal 
and state privacy, security and fraud laws may prove costly. 

Privacy  Laws.    We  are  also  subject  to  laws  and  regulations  covering  data  privacy  and  the 
protection of health-related and other personal information. The legislative and regulatory landscape for 
privacy and data protection continues to evolve, and there has been an increasing focus on privacy and 
data protection issues which may affect our business, including recently enacted laws in all jurisdictions 
where  we  operate.   Numerous  federal  and  state  laws,  including  state  security  breach  notification  laws, 
state  health  information  privacy  laws  and  federal  and  state  consumer  protection  laws,  govern  the 
collection, use and disclosure of personal information. In addition, if we successfully commercialize our 
drug candidates, we may obtain patient health information from healthcare providers who prescribe our 
products  and  research  institutions  we  collaborate  with,  and  they  are  subject  to  privacy  and  security 
requirements under the Health Insurance Portability and Accountability Act of 1996, as amended by the 
Health Information Technology for Economic and Clinical Health Act (“HIPAA”).   Although we are not 
directly  subject  to  HIPAA  other  than  with  respect  to  providing  certain  employee  benefits,  we  could 
potentially  be  subject  to  criminal  penalties  if  we  knowingly  obtain  or  disclose  individually  identifiable 
health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted 
by HIPAA. 

13 

 
Other  Requirements.    Companies  that  manufacture  or  distribute  drug  products  that  are  the 
subject  of  approved  NDAs  must  meet  other  regulatory  requirements,  including  reporting  and 
record-keeping obligations. 

Coverage and Reimbursement

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

Our ability to commercialize any products successfully also will depend in part on the extent to 
which coverage and adequate reimbursement for these products and related treatments will be available in a 
timely manner from government third-party  payors,  including  government  healthcare  programs  such  as 
Medicare  and  Medicaid,  commercial  health  insurers  and  managed  care  organizations.    Government 
authorities  and  other  third-party  payors,  such  as  private  health  insurers  and  health  maintenance 
organizations,  determine  which  medications  they  will  cover  and  establish  reimbursement  levels.   
Third-party  payors  may  limit  coverage  to  specific  products  on  an  approved  list,  or  formulary,  which 
might  not  include  all  of  the  FDA  approved  products  for  a  particular  indication.    The  process  for 
determining whether  a  payor  will  provide  coverage for  a  product  may  be  separate  from  the  process  for 
setting the price or reimbursement rate that the payor will pay for the product once coverage is approved.     

A primary trend in the U.S. healthcare industry and elsewhere is cost containment.    Government 
healthcare  programs  and  other  third-party  payors  are  increasingly  challenging  the  prices  charged  for 
medical  products  and  services  and  examining  the  medical  necessity  and  cost-effectiveness  of  medical 
products  and  services,  in  addition  to  their  safety  and  efficacy,  and  have attempted to control costs by 
limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party 
payors are requiring that drug companies provide them with predetermined discounts from list prices and 
are  challenging  the  prices  charged  for  medical  products.  We  cannot  be  sure  that  coverage  and 
reimbursement  will  be  available  promptly  or  at  all  for  any  product  that  we  commercialize  and,  if 
reimbursement is available, what the level of reimbursement will be. Moreover, eligibility for coverage and 
reimbursement does not imply that any drug will be paid for in all cases. Limited coverage may impact the 
demand for, or the price of, any product candidate for which we obtain marketing approval. If coverage and 
reimbursement  are  not  available  or  reimbursement  is  available  only  to  limited  levels,  we  may  not 
successfully commercialize any product candidate for which we obtain marketing approval.   

Payors also are increasingly considering new metrics as the basis for reimbursement rates, such as 
average sales price (“ASP”), average manufacturer price, and actual acquisition cost. The existing data for 
reimbursement based on these metrics is relatively limited, although certain states have begun to survey 
acquisition cost data for the purpose of setting Medicaid reimbursement rates.    The Centers for Medicare 
and Medicaid Services (“CMS”), the federal agency that administers the Medicare and Medicaid programs, 
has made draft National Average Drug Acquisition Cost (“NADAC”), and draft National Average Retail 

14 

 
Price (“NARP”), data publicly available on at least a monthly basis.    In July 2013, CMS suspended the 
publication  of  draft  NARP  data,  pending  funding  decisions.    In  November  2013,  CMS  moved  to 
publishing final rather than draft NADAC data and has since made updated NADAC data publicly available 
on a weekly basis.    Therefore, it may be difficult to project the impact of these evolving reimbursement 
mechanics  on  the  willingness  of  payors  to  cover  any  products  that  we  are  able  to  successfully 
commercialize. 

If we successfully commercialize any of our products, we may participate in the Medicaid Drug 
Rebate  Program.    Participation  is  required  for  federal  funds  to  be  available  for  our  products  under 
Medicaid and Medicare Part B.    Under the Medicaid Drug Rebate Program, we would be required to pay a 
rebate  to  each  state  Medicaid  program  for  our  covered  outpatient  drugs  that  are  dispensed  to  Medicaid 
beneficiaries and paid for by a state Medicaid program as a condition of having federal funds being made 
available to the states for our drugs under Medicaid and Part B of the Medicare program.     

Federal law requires that any company that participates in the Medicaid Drug Rebate Program also 
participate  in  the  Public  Health  Service’s  340B  drug  pricing  program  in  order  for  federal  funds  to  be 
available  for  the  manufacturer’s  drugs  under  Medicaid  and  Medicare  Part  B.    The  340B  drug  pricing 
program  requires  participating  manufacturers  to  agree  to  charge  statutorily-defined  covered  entities  no 
more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs.    These 340B covered 
entities include a variety of community health clinics and other entities that receive health services grants 
from  the  Public  Health  Service,  as  well  as  hospitals  that  serve  a  disproportionate  share  of  low-income 
patients.     

In  addition,  in  order  to  be  eligible  to  have  its  products  paid  for  with  federal  funds  under  the 
Medicaid  and  Medicare  Part  B  programs  and  purchased  by  certain  federal  agencies  and  grantees,  a 
manufacturer  also  must  participate  in  the  Department  of  Veterans  Affairs  Federal  Supply  Schedule 
(“FSS”), pricing program, established by Section 603 of the Veterans Health Care Act of 1992 (“VHCA”).   
Under  this  program,  the  manufacturer  is  obligated  to  make  its  innovator  and  single  source  products 
available for procurement on an FSS contract and charge a price to four federal agencies, Department of 
Veterans  Affairs,  Department  of  Defense  (“DoD”),  Public  Health  Service,  and  Coast  Guard,  that  is  no 
higher  than  the  statutory  Federal  Ceiling  Price.    Moreover,  pursuant  to  regulations  issued  by  the  DoD 
TRICARE  Management  Activity  (“TMA”),  now  the  Defense  Health  Agency  (“DHA”),  to  implement 
Section 703 of the National Defense Authorization Act for Fiscal Year 2008, manufacturers are required to 
provide rebates on utilization of their innovator and single source products that are dispensed to TRICARE 
beneficiaries  by  TRICARE  network  retail  pharmacies.    The  formula  for  determining  the  rebate  is 
established  in  the  regulations  and  is  based  on  the  difference  between  the  annual  non-federal  average 
manufacturer price and the Federal Ceiling Price (these price points are required to be calculated by us 
under  the  VHCA).  The  requirements  under  the  340B,  FSS,  and  TRICARE  programs  could  reduce  the 
revenue  we  may  generate  from  any  products  that  are  commercialized  in  the  future  and  could  adversely 
affect our business and operating results. 

There  may  be  significant  delays  in  obtaining  coverage  and  reimbursement  for  newly  approved 
drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or 
comparable foreign regulatory authorities. Moreover, eligibility for coverage and reimbursement does not 
imply  that  a  drug  will  be  paid  for  in  all  cases  or  at  a  rate  that  covers  our  costs,  including  research, 
development, manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, 
may also not be sufficient to cover our costs and may only be temporary. Reimbursement rates may vary 
according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement 
levels already set for lower cost drugs and may be incorporated into existing payments for other services.   
Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare 
programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from 

15 

 
countries where they may be sold at lower prices than in the United States. Limited  coverage  may  impact 
the  demand  for,  or  the  price  of,  any  product  candidate  for  which  we  obtain  marketing  approval.   
Third-party  payors  also  may  seek  additional  clinical  evidence,  including  expensive  pharmacoeconomic 
studies, beyond the data required to obtain marketing approval, demonstrating clinical benefits and value 
in  specific  patient  populations,  before  covering  our  products  for  those  patients.    If  reimbursement  is 
available  only  for  limited  indications,  we  may  not  be  able  to  successfully  commercialize  any  product 
candidate  for  which  we  obtain  marketing  approval.    Our  inability  to  promptly  obtain  coverage  and 
profitable reimbursement rates from both government-funded and private payors for any approved products 
that we develop could have a material adverse effect on our operating results, our ability to raise capital 
needed to commercialize products and our overall financial condition. 

United States Healthcare Reform 

The  United  States  and  many  foreign  jurisdictions  have  enacted  or  proposed  legislative  and 
regulatory changes affecting the healthcare system that could prevent or delay marketing approval of our 
product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any 
product  candidate  for  which  we  obtain  marketing  approval.  The  United  States  government,  state 
legislatures  and  foreign  governments  also  have  shown  significant 
implementing 
cost-containment  programs  to  limit  the  growth  of  government-paid  healthcare  costs,  including  price 
controls, restrictions on reimbursement and requirements for substitution of generic products for branded 
prescription drugs.

in 

In recent years, Congress has considered reductions in Medicare reimbursement levels for drugs 
administered by physicians. CMS, the agency that administers the Medicare and Medicaid programs, also 
has authority to revise reimbursement rates and to implement coverage restrictions for some drugs. Cost 
reduction initiatives and changes in coverage implemented through legislation or regulation could decrease 
utilization of and reimbursement for any approved products, which in turn would affect the price we can 
receive  for  those  products.  While  Medicare  regulations  apply  only  to  drug  benefits  for  Medicare 
beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their 
own reimbursement rates. Therefore, any reduction in reimbursement that results from federal legislation or 
regulation may result in a similar reduction in payments from private payors. 

In March 2010, President Obama signed into law the Affordable Care Act.    This law substantially 
changes  the  way  healthcare  is  financed  by  both  governmental  and  private  insurers,  and  significantly 
impacts  the  pharmaceutical  industry.    The  Affordable  Care  Act  is  intended  to broaden  access  to  health 
insurance,  reduce  or  constrain  the  growth  of  healthcare  spending,  enhance  remedies  against  healthcare 
fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose 
new  taxes  and  fees  on  pharmaceutical  and  medical  device  manufacturers,  and  impose  additional  health 
policy  reforms.  Among  other  things,  the  Affordable  Care  Act  expanded  manufacturers’  rebate  liability 
under the Medicaid Drug Rebate Program by increasing the minimum Medicaid rebate for both branded 
and generic drugs, expanded the 340B program, and revised the definition of average manufacturer price 
(“AMP”), which could increase the amount of Medicaid drug rebates manufacturers are required to pay to 
states.  The  legislation  also  extended  Medicaid  drug  rebates,  previously  due  only  on  fee-for-service 
Medicaid utilization, to include the utilization of Medicaid managed care organizations as well and created 
an alternative rebate formula for certain new formulations of certain existing products that is intended to 
increase  the  amount  of  rebates  due  on  those  drugs.    In  2012,  CMS  issued  proposed  regulations  to 
implement the changes to the Medicaid program under the Affordable Care Act, but CMS has not yet issued 
final regulations.    CMS is currently expected to release the final regulations in 2015.    Although it is too 
early  to  determine  the  full  effect  of  the  Affordable  Care  Act,  this  law  appears  likely  to  continue  the 
downward  pressure  on  pharmaceutical  pricing,  especially  under  the  Medicare  program,  and  may  also 
increase our regulatory burdens and operating costs. 

16 

 
The Affordable Care Act requires pharmaceutical manufacturers of branded prescription drugs to 
pay  a  branded  prescription  drug  fee  to  the  federal  government.    Each  individual  pharmaceutical 
manufacturer pays a prorated share of the branded prescription drug fee of $3.0 billion in 2015, based on the 
dollar  value  of  its  branded  prescription  drug  sales  to  certain  federal  programs  identified  in  the  law.   
Furthermore, the new law requires manufacturers to provide a 50% discount off the negotiated price of 
prescriptions filled by beneficiaries in the Medicare Part D coverage gap, referred to as the “donut hole.”   

The Affordable Care Act also expanded the Public Health Service’s 340B drug pricing discount 
program.    As noted above, the 340B drug pricing program requires participating manufacturers to agree to 
charge statutorily-defined covered entities no more than the 340B “ceiling price” for the manufacturer’s 
covered  outpatient  drugs.    The  Affordable  Care  Act  expanded  the  340B  program  to  include  additional 
types  of  covered  entities:  certain  free-standing  cancer  hospitals,  critical  access  hospitals,  rural  referral 
centers and sole community hospitals, each as defined by the Affordable Care Act. The Affordable Care 
Act  exempts  “orphan  drugs”—those  designated  under  section  526  of  the  Food,  Drug,  and  Cosmetic 
Act—from  the  ceiling  price  requirements  for  these  newly-eligible  entities.    The  Health  Resources  and 
Services  Administration,  or  HRSA,  which  administers  the  340B  program,  issued  an  interpretive  rule  to 
implement  the  orphan  drug  exception  which  interprets  the  orphan  drug  exception  narrowly.  It  exempts 
orphan drugs from the ceiling price requirements for the newly eligible entities only when the orphan drug 
is used for its orphan indication. The newly eligible entities are entitled to purchase orphan drugs at the 
ceiling price when the orphan drug is not used for its orphan indication. A manufacturer trade group has 
filed a lawsuit challenging the interpretive rule as inconsistent with the statutory language. That challenge 
remains ongoing. The uncertainty regarding how the statutory orphan drug exception will be applied will 
increase the complexity of compliance, will make compliance more time-consuming, and could negatively 
impact  our  results  of  operations  if  we  are  able  to  commercialize  our  products.  If  HRSA's  narrow 
interpretation of the scope of the orphan drug exception prevails, it could potentially negatively impact the 
price we are paid by certain entities for orphan drugs that we successfully commercialize and increase the 
complexity  of  compliance  with  the  340B  program.  In  addition,  because  the  340B  ceiling  price  is 
determined based on AMP and Medicaid drug rebate data, the revisions to the Medicaid rebate formula and 
AMP definition described above could cause the required 340B discounts to increase. 

In addition, other legislative changes have been proposed and adopted since the Affordable Care 
Act was enacted.    For example, recent legislative enactments have resulted in Medicare payments being 
subject to a two percent reduction, referred to as sequestration, until 2024.    Continuation of sequestration 
or enactment of other reductions in Medicare reimbursement for drugs could affect our ability to achieve 
a profit on any candidate products that are approved for marketing.   

We expect that the Affordable Care Act, as well as other healthcare reform measures that have and 
may be adopted in the future, may result in more rigorous coverage criteria and in additional downward 
pressure  on  the  price  that  we  receive  for  any  approved  product  and  could  seriously  harm  our  future 
revenues. Any reduction in reimbursement from Medicare, Medicaid, or other government programs may 
result  in  a  similar  reduction  in  payments  from  private  payors.  The  implementation  of  cost  containment 
measures  or  other  healthcare  reforms  may  prevent  us  from  being  able  to  generate  revenue,  attain 
profitability or commercialize our products. 

Foreign Regulation

In  addition  to  regulations  in  the  United  States,  we  will  be  subject  to  a  number  of  significant 
regulations  in  other  jurisdictions  regarding  clinical  trials,  approval,  manufacturing,  marketing  and 
promotion and safety reporting.    These requirements and restrictions vary from country to country, but 

17 

 
 
in many instances are similar to the United States requirements, and failure to comply with them could 
have the same negative effects as noncompliance in the United States. 

Sales and Marketing 

We do not currently have the sales and marketing infrastructure in place that would be necessary 
to  sell  and  market  products.  As  our  drug  candidates  progress  in  clinical  trials,  we  may  build  the 
commercial  infrastructure  that  would  be  needed  to  successfully  market  and  sell  any  successful  drug 
candidate. For drug candidates that may require larger clinical trials or sales efforts, we intend to establish 
strategic alliances and partnerships with large pharmaceutical companies during the development process. 

Research Technologies 

Our research technologies are focused on our proprietary multi-target aimed ligands platform and 
nano-based  drug  delivery,  which  are  described  further  below.  For  a  discussion  of  collaboration 
arrangements pursuant to which we obtain research and development services from universities, research 
institutions and other organizations, see “Collaboration and License Agreements” in this Item 1. 

The Inhibitors of Multi-Expression Signals (TIMES) 

TIMES  is  our  platform  for  discovering  ligands,  which  are  molecules  coordinated  to  a  central 
atom or molecule in a larger chemical complex, that target multi-expression signals. Because cancer is a 
complex disease caused by multiple factors as well as genetic modifications, cancer treatment involves a 
combination of drugs with different mechanisms of action, which may result in compounding the degree 
and  extent  of  toxicities  to  which  a  patient  is  exposed.    TIMES  permits  us  to  control  multiple  targets 
important  for  cancer  proliferation  with  a  single  agent.    In  doing  so,  we  utilize  a  proprietary, 
genomics-based  integrated,  gene  expression  system  to  identify potentially  important  targets  that  control 
multiple genes or signaling events in cancer cells. 

3-D Gateway of Ligand Discovery (3-D GOLD) 

3-D  GOLD  is  a  drug  discovery  platform  that  integrates  three-dimensional  (“3D”)  molecular 
modeling, databases of chemicals and proteins and ligand filtering and generation. The chemical database 
contains  3D  structures  of  approximately  seven  million  compounds.  Our  proprietary  docking  tools 
quantitative structure-activity relationship tool for innovative discovery are parts of the platform. Ligand 
filtering  highlights  similarities  in  pharmacophore  and  3D  fingerprinting,  while  ligand  generation  helps 
optimize the identification of such similarities. 

Nano-medicine Drug Delivery   

We have developed unique proprietary drug delivery nano-systems that we believe may increase 
the availability of a drug at the disease site, minimize adverse reactions, and provide longer duration of 
action.  We  are  currently  testing  multiple  nanoliposomal-  and  nanopolymer-based  anticancer  drugs.   
RX-21101  is  an  investigational  nanoliposomal-based  drug,  and  Archexin-Nano  is  an  investigational 
nanopolymer-based anticancer drug. 

Manufacturing and Distribution 

We  have  no  experience  in  drug  formulation  or  manufacturing,  and  we  lack  the  resources  and 
expertise  to  formulate  or  manufacture  our  own  drug  candidates  internally.  Therefore,  we  rely  on 

18 

 
third-party  expertise  to  support  us  in  this  area.  We  have  entered  into  contracts  with  third-party 
manufacturers to manufacture, supply, store and distribute supplies of our drug candidates for our clinical 
trials. If any of our drug candidates receive FDA approval, we expect to rely on third-party contractors to 
manufacture  our  drugs.  We  have  no  current  plans  to  build  internal  manufacturing  capacity  for  any 
product, and we have no long-term supply arrangements. 

Intellectual Property   

We  generally  seek  proprietary  patent  and  intellectual  property  (“IP”)  protection  for  our  drug 
candidates, processes, and other know-how. In addition to patent protection, we rely upon trade secrets, 
know-how, continuing technological innovation and licensing opportunities to develop and safeguard and 
maintain our IP. 

We hold U.S. and foreign patents for our drug candidates that expire from 2020 to 2030. We hold 
U.S. patents for Archexin, RX-3117 and Supinoxin. We also hold multiple foreign patents for Archexin, 
RX-3117, and Supinoxin.    Additional U.S. and foreign patent applications related to Archexin, RX-3117, 
Supinoxin, and RX-21101 are pending.  

In 2014, we were granted a U.S. patent for a novel targeted cancer drug delivery platform, and 

multiple foreign patents for novel anti-tumor isoquinolinamine compounds. 

In  February 2005,  we  in-licensed  the  intellectual  property  rights  to  Zoraxel  and  Serdaxin  from 
Revaax  Pharmaceuticals,  LLC  (“Revaax”).   Under  the  agreement  with  Revaax,  we  obtained  exclusive 
rights  to  four  U.S.  and  several  foreign  patents  related  to Serdaxin  and  to  two  U.S.  patents  related  to 
Zoraxel.   We  also  have  rights  to  additional  pending  U.S.  and  foreign  patent  applications  related  to 
Zoraxel and Serdaxin.   See “Collaboration and License Arrangements” below for additional information. 

Collaboration and License Arrangements 

We have numerous collaborative research and development relationships with universities, research 

institutions pharmaceutical companies and other organizations. 

The University of Maryland Baltimore (“UMB”)  

On  February  1,  2007,  we  entered  into  a  Maryland  Industrial  Partnership  Agreement  with  UMB  to 
collaborate with and sponsor the joint development of polymer-drug conjugates for the targeted delivery 
of cancer drugs.  Intellectual property made or developed under this agreement is jointly owned by us and 
UMB. 

In  July  2013,  we  entered  into  an  exclusive  license  agreement  with  UMB  for  a  novel  drug  delivery 
platform,  Nano-Polymer-Drug  Conjugate  Systems.    This  platform  combines  existing  chemotherapeutic 
agents  with  a  proprietary  polymer  carrier  that  contains  a  signaling  moiety  to  direct  the  agents  into  a 
tumor.    RX-21101  is  our  first  drug  candidate  utilizing  this  platform  and  is  a  conjugated  form  of 
docetaxel,  a  common  chemotherapy  agent.    This  agreement  requires  us  to  make  payments  to  UMB  if 
RX-21101  or  any  other  products  developed  from  the  licensed  delivery  platform  achieve  development 
milestones.     

Ohio State University 

In  October  2013,  we  entered  into  an  exclusive  license  agreement  with  the  Ohio  State  Innovation 
Foundation, an affiliate of the Ohio State University, for a novel oligonucleotide drug delivery platform, 
Lipid-Coated  Albumin  Nanoparticle  (“LCAN”).    The  LCAN  platform  incorporates  both  cationic  lipid 
and  cationized  albumin  that  can  form  an  electrostatic  complex  with  oligonucleotides  and  be 

19 

 
co-encapsulated by lipids.    Archexin-Nano is our first drug candidate to be developed with this platform. 
The agreement requires us to make payments to the Ohio State if any products from the licensed delivery 
platform achieve development milestones.     

Korea Research Institute of Chemical Technology (“KRICT”) 

On  June  22,  2009,  we  entered  into  a  license  agreement  with  KRICT  to  acquire  all  intellectual 
property  related  to  Quinoxaline-Piperazine  derivatives,  which  includes  Supinoxin.    We  paid  an  initial 
license fee of $100,000 in July 2009, and will pay $1,000,000 to KRICT upon marketing approval from 
the FDA for the first commercial product stemming from the agreement. 

Rexgene Biotech Co., Ltd. (“Rexgene”) 

On  February  6,  2003,  we  entered  into  a  research  collaboration  agreement  with  Rexgene,  which  is 
engaged in the development of pharmaceutical products in Asia. Rexgene has agreed to assist us with the 
research,  development  and  clinical  trials  necessary  for  registration  of  Archexin  in  Asia.    Under  the 
agreement,  Rexgene  has  exclusive  rights  to  license,  sublicense,  make,  have  made,  use,  sell  and  import 
Archexin in Asia. In accordance with the agreement, Rexgene paid the us a one-time fee of $1,500,000 in 
2003.  Rexgene  also  agreed  to  pay  us  a  royalty  fee  of  3%  of  net  sales  of  licensed  products  related  to 
Archexin in all countries in Asia by Rexgene or any sublicensee of Rexgene. 

The agreement expires upon the last to expire of all U.S. and foreign patents presently or in the future 
issued that cover Archexin, or, if no licensed patent is issued, within 20 years from the date of execution 
of  the  agreement.  A  breach  of  the  agreement  by  either  party  give  the  non-breaching  party  the  right  to 
terminate the agreement upon 90 days written notice of termination specifying the obligations breached, 
provided that within said 90 days the breaching party does not remedy the breach.   

Revaax Pharmaceuticals LLC (“Revaax”) 

On February 10, 2005, we in-licensed on an exclusive basis, with the right to sublicense, all of the IP 
of Revaax with respect to certain chemical structures that have demonstrated in pre-clinical research the 
potential  to  treat  certain  behavioral  disorders,  such  as  anxiety,  depression  and  cognitive  disorders  (the 
“Licensed  Products”),  which  includes  four  patents  and  multiple  patent  applications.  This  intellectual 
property was used to develop Serdaxin and Zoraxel.    This agreement expires upon the expiration of the 
royalty  term  for  all  Licensed  Products  in  all  countries,  which  is no  earlier  than  August  2020  and  could 
extend to August 2024.   

Under the agreement, we paid Revaax an initial license fee over a period of two years beginning in 
2005.  We  also  agreed  to  make  payments  to  Revaax  upon  the  achievement  of  certain  development 
milestones, such as dosing the first patient in a Phase III clinical trial or other controlled study in humans 
of  the  efficacy  and  safety  for  a  Licensed  Product  and  obtaining  approval  by  any  federal,  state  or  local 
regulatory, department, bureau or other governmental entity necessary prior to the commercial sale for a 
Licensed  Product.  We  are  not  obligated  to  make  any  payments  for  development  milestone  events  for 
which  we  receive  non-creditable  upfront  fees  or  milestone  payments  received  from  any  sublicense  in 
connection with the development and commercialization of a Licensed Product by such sublicense, less 
any  license  fees,  milestone  payments,  or  royalties  payable  by  us  to  a  third  party  under  any  technology 
acquisition agreement in connection with the development or commercialization of a Licensed Product, 
but specifically excluding any royalties revenues derived from any sublicense agreements. 

In  addition  to  milestone  payments,  we  agreed  to  pay  Revaax  royalty  payments  on  all  sales  of  a 
Licensed Product to third parties. Such royalty payments are equal to a low single digit percentage of the 
aggregate net sales of the Licensed Product, with the percentage increasing in relation to the aggregate net 
sales. Royalty payments for a Licensed Product expire upon the later of (a) the expiration of any claim of 

20 

 
an issued and unexpired patent of the Licensed Product that has not been held unenforceable or invalid 
and that has not been disclaimed or admitted to be invalid or unenforceable through reissue or otherwise 
and (b) 10 years after the first commercial sale of the Licensed Product. Royalty payments are reduced 
upon expiration of any patent claims for the Licensed Product within a particular country. 

Total Research and Development Costs 

We  have  incurred  research  and  development  costs  of  $7,015,901  and  $3,253,139  for  the  years 
ended December 31, 2014 and 2013 respectively.    Research and development costs primarily consist of 
clinical trials and pre-clinical development costs, as well as payroll costs for research and development 
personnel.   

Employees 

We  currently  have  22  full-time  employees,  all  of  whom  are  based  either  at  our  Rockville, 
Maryland  office  or  our  Germantown,  Maryland  lab  facility.    Our  employees  are  not  covered  by  any 
collective  bargaining  agreement  and  we  have  never  experienced  a  work  stoppage.    We  believe  our 
relationships with our employees are satisfactory.

Item 1A.    Risk Factors. 

You should carefully consider the risks described below together with the other information included in 
this Form 10-K. Our business, financial condition or results of operations could be adversely affected by 
any of these risks. If any of these risks occur, the value of our common stock could decline.

Risks Related to Our Financial Position and Capital Needs 

We  currently  have  no  product  revenues,  have  incurred  negative  cash  flows  from  operations  since 
inception and will need to raise additional capital to operate our business.

To  date,  we  have  generated  no  product  revenues  and  have  incurred  negative  cash  flow  from 
operations.  Until  we  receive  approval  from  the  FDA  and  other  regulatory  authorities  for  our  drug 
candidates, we cannot sell our drugs and will not have product revenues. We expect to continue to incur 
significant  development  and  other  expenses  related  to  our  ongoing  operations.    Therefore,  for  the 
foreseeable  future,  we  will  have  to  fund  all  of  our  operations  and  capital  expenditures  from  the  net 
proceeds of equity or debt offerings, cash on hand, licensing fees and grants, if any.    If we are not able to 
raise sufficient funds, we will have to reduce our research and development activities. We will first reduce 
research and development activities associated with our pre-clinical compounds. To the extent necessary, 
we will then  reduce our research  and development  activities  related  to some  or all of our clinical stage 
product candidates.   

Unforeseen events, difficulties, complications and delays may occur that could cause us to utilize 
our existing capital at a faster rate than projected, including the progress of our research and development 
efforts, the cost and timing of regulatory approvals and the costs of protecting our intellectual property 
rights.  We  may  seek  additional  financing  to  implement  and  fund  other  drug  candidate  development, 
clinical trial and research and development efforts, including clinical trials for other new drug candidates, 
as well as other research and development projects. 

We will need additional financing to continue to develop our drug candidates, which may not be 
available  on  favorable  terms,  if  at  all.  If  we  are  unable  to  secure  additional  financing  in  the  future  on 
acceptable terms, or at all, we may be unable to complete our planned pre-clinical and clinical trials or 
obtain  approval  of  our  drug  candidates  from  the  FDA  and  other  regulatory  authorities.  In  addition,  we 
may be forced to reduce or discontinue product development or product licensing, reduce or forego sales 
and  marketing  efforts  and  forego  attractive  business  opportunities  in  order  to  improve  our  liquidity  to 
enable us to continue operations. Any additional sources of financing will likely involve the sale of our 
equity securities or securities convertible into our equity securities, which may have a dilutive effect on 
our stockholders. 

We are not currently profitable and may never become profitable.

To  date,  we  have  generated  no  product  revenues  and  have  incurred  negative  cash  flow  from 
operations.  Our  accumulated  deficit  as  of  December  31,  2014  and  2013  was  $91,332,308  and 
$72,810,707,  respectively.  For  the  years  ended  December  31,  2014,  and  2013,  we  had  net  losses  of 
$18,521,601 and $9,499,424, respectively. Even if we succeed in developing and commercializing one or 
more  of  our  drug  candidates,  we  expect  to  incur  substantial  losses  for  the  foreseeable  future  and  may 
never  become  profitable.  We  also  expect  to  continue  to  incur  significant  operating  and  capital 
expenditures and anticipate that our expenses will increase substantially in the foreseeable future, based 
on the following considerations: 

22 

 
(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

continued pre-clinical development and clinical trials for our current and new drug candidates; 

finding suitable partners to help us research, develop and commercialize new drug candidates; 

efforts to seek regulatory approvals for our drug candidates; 

implementing additional internal systems and infrastructure; 

in-licensing additional technologies to develop; and 

hiring additional personnel or entering into relationships with third parties to perform functions 
that we are unable to perform on our own. 

We also expect to continue to experience negative cash flow for the foreseeable future as we fund 
our operations and capital expenditures. Until we have the capacity to generate revenues, we are relying 
upon  outside  funding  resources  to  fund  our  cash  flow  requirements.  If  these  resources  are  depleted  or 
unavailable,  we  may  be  unable  to  continue  to  expand  our  operations  or  otherwise  capitalize  on  our 
business opportunities, and our business, financial condition and results of operations would be materially 
adversely affected. 

We have a limited operating history, and we have not demonstrated an ability to commercialize drug 
candidates.

We are a clinical-stage company with a limited number of drug candidates. We currently do not 
have  any  products  that  have  gained  regulatory  approval,  and  we  have  not  demonstrated  an  ability  to 
perform the functions necessary for the successful commercialization of any of our drug candidates. The 
successful commercialization of our drug candidates will require us to first perform a variety of functions, 
including: 

(cid:31)

(cid:31)

(cid:31)

(cid:31)

conducting pre-clinical and clinical trials; 

participating in regulatory approval processes; 

formulating and manufacturing products; and 

conducting sales and marketing activities. 

To  date,  our  operations  have  been  limited  to  organizing  and  staffing  the  Company,  acquiring, 
developing  and  securing  our  proprietary  technology,  and  undertaking  drug  candidate  research  and 
development,  including  pre-clinical  trials  and  clinical  trials  of  our  principal  drug  candidates.  These 
operations provide a limited basis for assessing our ability to commercialize drug candidates. 

Several  of  our  drug  candidates  are  in  clinical  trials,  which  are  very  expensive,  time-consuming  and 
difficult to design and implement.

Our drug candidates are in various stages of development and require extensive clinical testing. 

Such  testing  is  expensive  and  time-consuming  and  requires  specialized  knowledge  and  expertise.   
Archexin entered a Phase IIa clinical trial in January 2014, RX-3117 entered a Phase Ib clinical trial in 
January 2014, and Supinoxin entered a Phase I clinical trial in August 2013.

they are subject to rigorous regulatory requirements. The clinical trial process is also time-consuming, and 
the outcome is not certain; the results of pre-clinical studies and early clinical trials may not be predictive 
of the results of later-stage clinical trials. We estimate that clinical trials of our current drug candidates 
will take multiple years to complete. Furthermore, failure can occur at any stage of a clinical trial, and we 
could  encounter  problems  that  cause  us  to  abandon  or  repeat  clinical  trials.  The  commencement  and 
completion of clinical trials may be delayed or precluded by a number of factors, including: 

(cid:31)

(cid:31)

(cid:31)

delay  or  failure  in  reaching  agreement  with  the  FDA  or  a  foreign  regulatory  authority  on  the 
design of a given trial, or in obtaining authorization to commence a trial; 

delay  or  failure  in  reaching  agreement  on  acceptable  terms  with  prospective  contract  research 
organizations (“CROs”) and clinical trial sites; 

delay or failure in obtaining approval of an IRB to conduct a clinical trial at a given site; 

(cid:31) withdrawal of clinical trial sites from our clinical trials as a result of changing standards of care of 

the ineligibility of a site to participate;

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

delay or failure in recruiting and enrolling study subjects; 

delay or failure in having subjects complete a clinical trial or return for post-treatment follow up; 

clinical  sites  or  investigators  deviating  from  trial  protocol,  failing  to  conduct  the  trial  in 
accordance with applicable regulatory requirements, or dropping out of a trial; 

inability to identify and maintain a sufficient number of trial sites; 

failure of third-party clinical trial managers to meet their contractual obligations or deadlines; 

the need to modify a study protocol; 

unforeseen safety issues; 

emergence of dosing issues; 

lack of effectiveness during clinical trials; 

change in the standard of care of the indication being studied; 

reliance on third-party suppliers for the clinical trial supply of drug candidates; 

inability to monitor patients adequately during or after treatment; 

lack of sufficient funding to finance the clinical trials; and 

changes in governmental regulations or administrative action. 

We, the FDA or an IRB may suspend a clinical trial at any time if it appears that we are exposing 
participants to unacceptable health risks or if the FDA finds deficiencies in our IND applications or the 

24 

 
conduct of these trials. Additionally, we may have difficulty enrolling patients in our clinical trials.    If 
we  experience  such  difficulties,  we  may  not  be  able  to  complete  a  clinical  trial  or  we  may  experience 
significant delays in completing a clinical trial.  

If  the  results  of  our  clinical  trials  fail  to  support  the  claims  of  any  of  our  drug  candidates,  the 
completion  of  development  of  that  candidate  may  be  significantly  delayed,  or  we  may  be  forced  to 
abandon  development  altogether,  which  will  significantly  impair  our  ability  to  generate  product 
revenues.

Even if our clinical trials are completed as planned, we cannot be certain that clinical results will 
support our drug candidate claims. Success in pre-clinical testing and early clinical trials does not ensure 
that later clinical trials will be successful, and we cannot be sure that the results of later clinical trials will 
replicate  the  results  of  prior  clinical  trials  and  pre-clinical  testing.  The  clinical  trial  process  may  fail  to 
demonstrate that one or more of our drug candidates is safe and effective for indicated uses. As a result, 
we  may  have  to  conduct  additional  clinical  trials  or may  decide  to  abandon  a drug  candidate,  in  which 
case  we  may  never  recognize  any  revenue  related  to  such  candidate.  Standard  of  care  treatments  may 
change,  which  may  require  additional  clinical  trials.  Repeating  clinical  trials  or  conducting  additional 
clinical trials will delay the filing of an NDA and, ultimately, delay our ability to commercialize our drug 
candidates and generate product revenues.   

We  may  not  obtain  the  necessary  U.S.  or  worldwide  regulatory  approvals  to  commercialize  our  drug 
candidates,  and  we  cannot  guarantee  how  long  it  will  take  the  FDA  or  other  comparable  regulatory 
agencies to review applications for our drug candidates.

We  will  need  FDA  approval  to  commercialize  our  drug  candidates  in  the  United  States  and 
approvals  from  the  comparable  regulatory  authorities  to  commercialize  our  drug  candidates  in  foreign 
jurisdictions.

The  time  it  takes  to  obtain  approval,  either  in  the  United  States  or  foreign  jurisdictions,  is 
unpredictable,  but  typically  takes  many  years,  depending  upon  a  variety  of  factors,  including  the  type, 
complexity  and  novelty  of  the  drug  candidate.  Obtaining  approval  requires  substantial  resources  and  is 
subject to regulatory authorities’ substantial discretion.    In addition, approval policies, regulations or the 
type and amount of clinical data necessary to gain approval may change during the course of a product 
candidate’s  development  and  may  vary  among  jurisdictions.  We  cannot  guarantee  that  any  of  our  drug 
candidates will ultimately be approved by the FDA or any other regulatory authority, or the length of time 
obtaining approval will take.   One of our drug candidates, Archexin is an ASO compound. To date, the 
FDA has approved very few ASO compounds. In addition, Archexin, and Archexin-Nano are in the drug 
class known as Akt-1 inhibitors that to date have not been approved by the FDA, nor have we submitted 
an  NDA.  After  clinical  trials  are  completed,  the  FDA  has  substantial  discretion  in  the  drug  approval 
process  and  may  require  us  to  conduct  additional  pre-clinical  and  clinical  testing  or  to  perform 
post-marketing studies. 

Our product candidates could fail to receive regulatory approval from the FDA or a comparable 

foreign authority for a variety of reasons, including: 

(cid:31)

(cid:31)

(cid:31)

disagreement with the design or implementation of our clinical trials; 

failure  to  demonstrate  to  the  authority’s  satisfaction  that  the  product  candidate  is  safe  and 
effective for the proposed indication; 

failure of clinical trials to meet the level of statistical significance required for approval; 

25 

 
(cid:31)

(cid:31)

(cid:31)

failure to demonstrate that the product’s benefits outweigh its risks; 

disagreement with our interpretation of pre-clinical or clinical data; and 

inadequacies in the manufacturing facilities or processes of third-party manufacturers. 

The FDA or a comparable foreign authority may require us to conduct additional pre-clinical and 
clinical  testing,  which  may  delay  or  prevent  approval  and  our  commercialization  plans  or  cause  us  to 
abandon the development program.    Further, any approval we receive may be for fewer or more limited 
indications than we request, may not include labeling claims necessary for successful commercialization 
of the product candidate or may be contingent upon our conducting costly post-marketing clinical trials,   
Any of these scenarios could materially harm the commercial prospects of a product candidate. 

Even  if  our  product  candidates  obtain  approval,  they  may  face  future  development  and  regulatory 
difficulties that can negatively affect commercial prospects. 

Even  if  we  obtain  approval  for  a  product  candidate,  it  would  be  subject  to  ongoing  regulatory 
requirements and restrictions of the FDA and comparable regulatory authorities regarding manufacturing, 
quality control, further development, labeling, packaging, storage, distribution safety surveillance, import, 
export, advertising, promotion, recordkeeping and reporting.    Failure by us or any of the third parties on 
which we rely to meet those requirements can lead to enforcement action that could significantly impair 
our  ability  to  successfully  commercialize  a  given  product.    If  the  FDA  or  a  comparable  regulatory 
authority  becomes  aware  of  new  safety  information,  it  can  impose  additional  restrictions  on  how  the 
product is marketed, if at all.   

There  is  no  assurance  that  any  of  our  products  that  has  received  or  will  receive  orphan  drug 
designation will subsequently obtain orphan drug exclusivity, or that any such exclusivity will provide 
the desired benefit.

Although we have obtained orphan drug designation for several uses of Archexin and one use of 
RX-3117 and may obtain additional orphan drug designation for these or other product candidates, we are 
not  assured  of  being  awarded  orphan  drug  exclusivity  or  the  enjoying  the  benefits  of  such  exclusivity, 
even if any of these products is approved for its orphan-designated use.    If another company also holding 
orphan  drug  designation  for  a  product  containing  the  same  active  moiety  intended  for  the  same  rare 
disease  or  condition  receives  approval  before  our  orphan-designated  product,  approval  of  our  product 
could be precluded for seven years, because of that product’s orphan drug exclusivity, unless we  could 
demonstrate our product to be clinically superior to the earlier-approved product.    Similarly, even if our 
orphan designated drug were approved first and awarded seven-year orphan drug exclusivity, it would not 
block approval of the other product, if that product were shown to be clinically superior, or if we fail to 
assure  a  sufficient  quantity  of  our  orphan  drug.    Additionally,  because  orphan  drug  exclusivity  is 
product-  and  indication-specific,  it  does  not  prevent  approval  of  another  drug  for  the  same  orphan 
indication or the same drug for a different use.   

If physicians and patients do not accept and use our drugs, our ability to generate revenue from sales 
of our products will be materially impaired.

Even if the FDA approves our drug candidates, physicians and patients may not accept and use 

them. Future acceptance and use of our products will depend upon a number of factors including: 

26 

 
 
(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

awareness of a drug’s availability and benefits; 

perceptions by members of the health care community, including physicians, about the safety and 
effectiveness of our drugs; 

pharmacological benefit and cost-effectiveness of our products relative to competing products; 

availability of reimbursement for our products from government or other third-party payors; 

effectiveness of marketing and distribution efforts by us and our licensees and distributors, if any; 
and

the price at which we sell our products. 

Because we expect sales of our current drug candidates, if approved, to generate substantially all 
of  our  product  revenues  for  the  foreseeable  future,  the  failure  of  any  of  these  drugs  to  find  market 
acceptance would harm our business and could require us to seek additional financing. 

Even if we are able to commercialize any of our product candidates, these products may become subject 
to unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives, 
which could harm our business. 

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

Our ability to commercialize any products successfully also will depend in part on the extent to 

which coverage and adequate reimbursement for these products and related treatments will be available in a 
timely manner from government third-party payors, including governmental healthcare programs such as 
Medicare and Medicaid, commercial health insurers and managed care organizations. Government 
authorities and other third-party payors, such as private health insurers and health maintenance 
organizations, determine which medications they will cover and establish reimbursement levels. 
Third-party payors may limit coverage to specific products on an approved list, or formulary, which 
might not include all of the FDA approved products for a particular indication.    The process for 
determining whether a payor will provide coverage for a product may be separate from the process for 
setting the price or reimbursement rate that the payor will pay for the product once coverage is approved. 

A primary trend in the U.S. healthcare industry and elsewhere is cost containment.    Government 

healthcare programs and other third-party payors are increasingly challenging the prices charged for 
medical products and services and examining the medical necessity and cost-effectiveness of medical 
products and services, in addition to their safety and efficacy, and have attempted to control costs by 
limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party 
payors are requiring that drug companies provide them with predetermined discounts from list prices and 

27 

 
are challenging the prices charged for medical products. We cannot be sure that coverage and 
reimbursement will be available promptly or at all for any product that we commercialize and, if 
reimbursement is available, what the level of reimbursement will be. Moreover, eligibility for coverage and 
reimbursement does not imply that any drug will be paid for in all cases. Limited coverage may impact the 
demand for, or the price of, any product candidate for which we obtain marketing approval. If coverage and 
reimbursement are not available or reimbursement is available only to limited levels, we may not 
successfully commercialize any product candidate for which we obtain marketing approval.   

Payors also are increasingly considering new metrics as the basis for reimbursement rates, such as 
average sales price (“ASP”), average manufacturer price, and actual acquisition cost. The existing data for 
reimbursement based on these metrics is relatively limited, although certain states have begun to survey 
acquisition cost data for the purpose of setting Medicaid reimbursement rates.    The Centers for Medicare 
and Medicaid Services (“CMS”), the federal agency that administers the Medicare and Medicaid programs, 
has made draft National Average Drug Acquisition Cost (“NADAC”), and draft National Average Retail 
Price (“NARP”), data publicly available on at least a monthly basis.    In July 2013, CMS suspended the 
publication of draft NARP data, pending funding decisions.    In November 2013, CMS moved to 
publishing final rather than draft NADAC data and has since made updated NADAC data publicly available 
on a weekly basis.    Therefore, it may be difficult to project the impact of these evolving reimbursement 
mechanics on the willingness of payors to cover any products that we are able to successfully 
commercialize. 

If we successfully commercialize any of our products, we may participate in the Medicaid Drug 

Rebate program.    Participation is required for federal funds to be available for our products under 
Medicaid and Medicare Part B.    Under the Medicaid Drug Rebate Program, we would be required to pay a 
rebate to each state Medicaid program for our covered outpatient drugs that are dispensed to Medicaid 
beneficiaries and paid for by a state Medicaid program as a condition of having federal funds being made 
available to the states for our drugs under Medicaid and Part B of the Medicare program.     

Federal law requires that any company that participates in the Medicaid Drug Rebate Program also 

participate in the Public Health Service’s 340B drug pricing program in order for federal funds to be 
available for the manufacturer’s drugs under Medicaid and Medicare Part B.    The 340B drug pricing 
program requires participating manufacturers to agree to charge statutorily-defined covered entities no 
more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs.    These 340B covered 
entities include a variety of community health clinics and other entities that receive health services grants 
from the Public Health Service, as well as hospitals that serve a disproportionate share of low-income 
patients.     

In addition, in order to be eligible to have its products paid for with federal funds under the 
Medicaid and Medicare Part B programs and purchased by certain federal agencies and grantees, a 
manufacturer also must participate in the Department of Veterans Affairs Federal Supply Schedule 
(“FSS”), pricing program, established by Section 603 of the Veterans Health Care Act of 1992 (“VHCA”).   
Under this program, the manufacturer is obligated to make its innovator and single source products 
available for procurement on an FSS contract and charge a price to four federal agencies, Department of 
Veterans Affairs, Department of Defense (“DoD”), Public Health Service, and Coast Guard, that is no 
higher than the statutory Federal Ceiling Price.    Moreover, pursuant to regulations issued by the DoD 
TRICARE Management Activity (“TMA”), now the Defense Health Agency (“DHA”), to implement 
Section 703 of the National Defense Authorization Act for Fiscal Year 2008, manufacturers are required to 
provide rebates on utilization of their innovator and single source products that are dispensed to TRICARE 
beneficiaries by TRICARE network retail pharmacies.    The formula for determining the rebate is 
established in the regulations and is based on the difference between the annual non-federal average 
manufacturer price and the Federal Ceiling Price (these price points are required to be calculated by us 
under the VHCA). The requirements under the 340B, FSS, and TRICARE programs could reduce the 

28 

 
revenue we may generate from any products that are commercialized in the future and could adversely 
affect our business and operating results. 

There  may  be  significant  delays  in  obtaining  coverage  and  reimbursement  for  newly  approved 
drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or 
comparable foreign regulatory authorities. Moreover, eligibility for coverage and reimbursement does not 
imply  that  a  drug  will  be  paid  for  in  all  cases  or  at  a  rate  that  covers  our  costs,  including  research, 
development, manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, 
may also not be sufficient to cover our costs and may only be temporary. Reimbursement rates may vary 
according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement 
levels already set for lower cost drugs and may be incorporated into existing payments for other services. 
Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare 
programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from 
countries where they may be sold at lower prices than in the United States.    Limited coverage may impact 
the  demand  for,  or  the  price  of,  any  product  candidate  for  which  we  obtain  marketing  approval.   
Third-party  payors  also  may  seek  additional  clinical  evidence,  including  expensive  pharmacoeconomic 
studies beyond the data required to obtain marketing approval, demonstrating clinical benefits and value 
in  specific  patient  populations,  before  covering  our  products  for  those  patients.    If  reimbursement  is 
available  only  for  limited  indications,  we  may  not  be  able  to  successfully  commercialize  any  product 
candidate  for  which  we  obtain  marketing  approval.      Our  inability  to  promptly  obtain  coverage  and 
profitable reimbursement rates from both government-funded and private payors for any approved products 
that we develop could have a material adverse effect on our operating results, our ability to raise capital 
needed to commercialize products and our overall financial condition. 

Changes in healthcare law and implementing regulations, including those based on recently enacted 
and future legislation, as well as changes in healthcare policy, may increase the difficulty and cost for us 
to commercialize our product candidates and affect the prices we may obtain. 

The United States and many foreign jurisdictions have enacted or proposed legislative and 
regulatory changes affecting the healthcare system that could prevent or delay marketing approval of our 
product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any 
product candidate for which we obtain marketing approval. The United States government, state 
legislatures and foreign governments also have shown significant interest in implementing 
cost-containment programs to limit the growth of government-paid healthcare costs, including price 
controls, restrictions on reimbursement and requirements for substitution of generic products for branded 
prescription drugs. 

In recent years, Congress has considered reductions in Medicare reimbursement levels for drugs 

administered by physicians. CMS also has authority to revise reimbursement rates and to implement 
coverage restrictions for some drugs. Cost reduction initiatives and changes in coverage implemented 
through legislation or regulation could decrease utilization of and reimbursement for any approved 
products, which in turn would affect the price we can receive for those products. While Medicare 
regulations apply only to drug benefits for Medicare beneficiaries, private payors often follow Medicare 
coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction 
in reimbursement that results from federal legislation or regulation may result in a similar reduction in 
payments from private payors. 

In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, 

as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the “Affordable 
Care Act”).    This law substantially changes the way healthcare is financed by both governmental and 
private insurers, and significantly impacts the pharmaceutical industry.    The Affordable Care Act is 
intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, 

29 

 
enhance remedies against healthcare fraud and abuse, add new transparency requirements for healthcare 
and health insurance industries, impose new taxes and fees on pharmaceutical and medical device 
manufacturers, and impose additional health policy reforms. Among other things, the Affordable Care Act 
expanded manufacturers’ rebate liability under the Medicaid Drug Rebate Program by increasing the 
minimum Medicaid rebate for both branded and generic drugs, expanded the 340B program, and revised 
the definition of average manufacturer price (“AMP”), which could increase the amount of Medicaid drug 
rebates manufacturers are required to pay to states. The legislation also extended Medicaid drug rebates, 
previously due only on fee-for-service Medicaid utilization, to include the utilization of Medicaid managed 
care organizations as well and created an alternative rebate formula for certain new formulations of certain 
existing products that is intended to increase the amount of rebates due on those drugs.    In 2012, CMS 
issued proposed regulations to implement the changes to the Medicaid program under the Affordable Care 
Act, but CMS has not yet issued final regulations.    CMS is currently expected to release the final 
regulations in 2015.    Although it is too early to determine the full effect of the Affordable Care Act, this 
law appears likely to continue the downward pressure on pharmaceutical pricing, especially under the 
Medicare program, and may also increase our regulatory burdens and operating costs. 

The Affordable Care Act requires pharmaceutical manufacturers of branded prescription drugs to 

pay a branded prescription drug fee to the federal government.    Each individual pharmaceutical 
manufacturer pays a prorated share of the branded prescription drug fee of $3.0 billion in 2015, based on the 
dollar value of its branded prescription drug sales to certain federal programs identified in the law.   
Furthermore, the new law requires manufacturers to provide a 50% discount off the negotiated price of 
prescriptions filled by beneficiaries in the Medicare Part D coverage gap, referred to as the “donut hole.”   

The Affordable Care Act also expanded the Public Health Service’s 340B drug pricing discount 

program.    The 340B drug pricing program requires participating manufacturers to agree to charge 
statutorily-defined covered entities no more than the 340B “ceiling price” for the manufacturer’s covered 
outpatient drugs.    The Affordable Care Act expanded the 340B program to include additional types of 
covered entities: certain free-standing cancer hospitals, critical access hospitals, rural referral centers and 
sole community hospitals, each as defined by the Affordable Care Act. The Affordable Care Act exempts 
“orphan drugs”—those designated under section 526 of the Food, Drug, and Cosmetic Act—from the 
ceiling price requirements for these newly-eligible entities.    The Health Resources and Services 
Administration (“HRSA”), which administers the 340B program, issued an interpretive rule to implement 
the orphan drug exception which interprets the orphan drug exception narrowly. It exempts orphan drugs 
from the ceiling price requirements for the newly eligible entities only when the orphan drug is used for its 
orphan indication. The newly eligible entities are entitled to purchase orphan drugs at the ceiling price when 
the orphan drug is not used for its orphan indication. A manufacturer trade group has filed a lawsuit 
challenging the interpretive rule as inconsistent with the statutory language. That challenge remains 
ongoing. The uncertainty regarding how the statutory orphan drug exception will be applied will increase 
the complexity of compliance, will make compliance more time-consuming, and could negatively impact 
our results of operations if we are able to commercialize our products. If HRSA's narrow interpretation of 
the scope of the orphan drug exception prevails, it could potentially negatively impact the price we are paid 
by certain entities for orphan drugs that we successfully commercialize and increase the complexity of 
compliance with the 340B program. In addition, because the 340B ceiling price is determined based on 
AMP and Medicaid drug rebate data, the revisions to the Medicaid rebate formula and AMP definition 
described above could cause the required 340B discounts to increase. 

In addition, other legislative changes have been proposed and adopted since the Affordable Care 
Act was enacted.    For example, recent legislative enactments have resulted in Medicare payments being 
subject to a two percent reduction, referred to as sequestration, until 2024. Continuation of sequestration or 
enactment of other reductions in Medicare reimbursement for drugs could affect our ability to achieve a 
profit on any candidate products that are approved for marketing.   

30 

 
We expect that the Affordable Care Act, as  well as other healthcare reform  measures that have 
and  may  be  adopted  in  the  future,  may  result  in  more  rigorous  coverage  criteria  and  in  additional 
downward pressure on the price that we receive for any approved product and could seriously harm our 
future  revenues.  Any  reduction  in  reimbursement  from  Medicare,  Medicaid,  or  other  government 
programs may result in a similar reduction in payments from private payors. The implementation of cost 
containment measures or other healthcare reforms may prevent us from being able to generate revenue, 
attain profitability or commercialize our products.   

If we are able to successfully commercialize any of our products and if we participate in the Medicaid 
drug  rebate  program  or  other  governmental  pricing  programs,  failure  to  comply  with  reporting  and 
payment  obligations  under  these  programs  could  result  in  additional  reimbursement  requirements, 
penalties,  sanctions  and  fines  which  could  have  a  material  adverse  effect  on  our  business,  financial 
condition, results of operations and growth prospects. 

The  Medicaid  Drug  Rebate  Program  and  other  governmental  pricing  programs  require 
manufacturers to report pricing data to the government.    Pricing calculations vary among products and 
programs and include average manufacturer price and best price for the Medicaid Drug Rebate Program, 
average sales price for certain categories of drugs that are paid under Part B of the Medicare program, and 
non-federal average manufacturer price for the FSS pricing program.    If we successfully commercialize 
any of our products and participate in such governmental pricing programs, we will be liable for errors 
associated with our submission of pricing data.    That liability could be significant.    For example, if we 
are found to have knowingly submitted false average manufacturer price, average sales price, best price, 
or  non-federal  average  manufacturer  price  information  to  the  government,  we  may  be  liable  for  civil 
monetary  penalties  in  the  amount  of  $100,000  per  item  of  false  information.    If  we  are  found  to  have 
made a misrepresentation in the reporting of average sales price, the statute provides for civil monetary 
penalties  of  up  to  $10,000  for  each  misrepresentation  for  each  day  in  which  the  misrepresentation  was 
applied.    Our  failure  to  submit  monthly/quarterly  average  manufacturer  price,  average  sales  price,  and 
best price, and quarterly/annual non-federal average manufacturer price data on a timely basis could result 
in a civil monetary penalty of $10,000 per day for each day the information is late beyond the due date.   
Such  failure  also  could  be  grounds  for  other  sanctions,  such  as  termination  from  the  Medicaid  Drug 
Rebate Program. 

Our  relationships  with  customers  and  third-party  payors  will  be  subject  to  applicable  anti-kickback, 
fraud  and  abuse,  transparency  and  other  healthcare  laws  and  regulations,  which  could  expose  us  to 
criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and 
diminished profits and future earnings. 

Healthcare providers, physicians and third-party payors play a primary role in the recommendation 
and  prescription  of  any  product  candidates  for  which  we  obtain  marketing  approval.  Our  future 
arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuse 
and other healthcare laws and regulations that may constrain the business or financial arrangements and 
relationships  through  which  we  market,  sell  and  distribute  our  products  for  which  we  obtain  marketing 
approval.  Restrictions  under  applicable  federal  and  state  healthcare  laws  and  regulations,  include  the 
following:   

(cid:31)

the federal Anti-Kickback Statute prohibits persons from, among other things, knowingly 
and  willfully  soliciting,  offering,  receiving  or  providing  remuneration,  directly  or 
indirectly,  in  cash  or  in  kind,  to  induce  or  reward,  or  in  return  for,  the  referral  of  an 
individual for the furnishing or arranging for the furnishing, or the purchase, lease or order, 

31 

 
or arranging for or recommending purchase, lease or order, any good or service for which 
payment may be made under a federal healthcare program such as Medicare and Medicaid; 

(cid:31)

(cid:31)

the federal civil False Claims Act imposes penalties, including through civil whistleblower 
or  qui  tam  actions,  against  individuals  or  entities  for,  among  other  things,  knowingly 
presenting, or causing to be presented, to the federal government, claims for payment that 
are false or fraudulent or making a false statement material to an obligation to pay money 
to  the  government  or  knowingly  concealing  or  knowingly  and  improperly  avoiding, 
decreasing, or concealing an obligation to pay money to the federal government; 

the  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA, 
imposes criminal liability for knowingly and willfully executing a scheme to defraud any 
healthcare benefit program, knowingly and willfully embezzling or stealing from a health 
care benefit program, willfully obstructing a criminal investigation of a health care offense, 
or knowingly and willfully making false statements relating to healthcare matters; 

(cid:31) HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical 
Health Act of 2009 and its implementing regulations, also imposes obligations on certain 
covered entity health care providers, health plans and health care clearinghouses as well as

the federal Open Payments program, created under Section 6002 of the Affordable Care 
Act and its implementing regulations, requires manufacturers of drugs, devices, biologics 
and  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid  or  the 
Children’s Health Insurance Program (with certain exceptions) to report annually to the 
CMS  information  related  to  “payments  or  other  transfers  of  value”  made  to  physicians 
(defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors)  and 
teaching  hospitals,  and  applicable  manufacturers  and  applicable  group  purchasing 
organizations  to  report  annually  CMS  ownership  and  investment  interests  held  by 
physicians (as defined above) and their immediate family members; and 

analogous  state  and  foreign  laws  and  regulations,  such  as  state  anti-kickback  and  false 
claims laws, which may apply to sales or marketing arrangements and claims involving 
healthcare items or services reimbursed by non-governmental third-party payors, including 
private insurers; state and foreign laws that require pharmaceutical companies to comply 
with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant 
compliance  guidance  promulgated  by  the  federal  government  or  otherwise  restrict 
payments  that  may  be  made  to  certain  healthcare  providers;  state  and  foreign  laws  that 
require drug manufacturers to report information related to payments and other transfers of 
value to physicians and other healthcare providers or marketing expenditures; and state and 
foreign  laws  that  govern  the  privacy  and  security  of  health  information  in  certain 
circumstances, many of which differ from each other in significant ways and often are not 
preempted by HIPAA, thus complicating compliance efforts. 

Efforts  to  ensure  that  our  business  arrangements  with  third  parties  will  comply  with  applicable 
healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities 
will conclude that our business practices may not comply with current or future statutes, regulations or case 
law interpreting applicable fraud and abuse or other healthcare laws and regulations. If our operations are 

32 

 
found to be in violation of any of these laws or any other governmental regulations that may apply to us, we 
may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, 
exclusion  from  government  funded  healthcare  programs,  such  as  Medicare  and  Medicaid,  and  the 
curtailment  or  restructuring  of  our  operations.  If  any  of  the  physicians  or  other  healthcare  providers  or 
entities with whom we expect to do business is found not to be in compliance with applicable laws, that 
person or entity may be subject to criminal, civil or administrative sanctions, including exclusions from 
government funded healthcare programs.    For a fuller discussion of the applicable anti-kickback fraud and 
abuse,  transparency  and  other  healthcare  laws  and  regulations  applicable  to  our  business,  see  Item  1, 
‘Description of Business – Government Regulation” 

Developments by competitors may render our products or technologies obsolete or non-competitive.

We  compete  against  fully  integrated  pharmaceutical  companies  and  smaller  companies  that  are 
collaborating  with  larger  pharmaceutical  companies  as  well  as  academic  institutions,  government 
agencies and other public and private research organizations. Many of these competitors, either alone or 
together  with  their  collaborative  partners,  operate  larger  research  and  development  programs  or  have 
substantially greater financial resources than we do, as well as more experience in: 

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

developing drugs; 

undertaking pre-clinical testing and human clinical trials; 

obtaining FDA and other regulatory approvals of drugs; 

formulating and manufacturing drugs; and 

launching, marketing and selling drugs. 

Large  pharmaceutical  companies  currently  sell  both  generic  and  proprietary  compounds  for  the 
treatment  of  cancer.  In  addition,  companies  pursuing  different  but  related  fields  represent  substantial 
competition. Many of these organizations have substantially greater capital resources, larger research and 
development staff and facilities, longer drug development history in obtaining regulatory approvals and 
greater manufacturing and marketing capabilities than we do. These organizations also compete with us to 
attract qualified personnel, parties for acquisitions, joint ventures or other collaborations. Our competitors 
may succeed in developing products that are more effective and/or safe than ours, which could render our 
product  candidates  less  competitive  prior  to  recovery  by  us  of  expenses  incurred  with  respect  to  their 
development. 

If we are unable to successfully manage our growth, our business may be harmed.

In  addition  to  our  own  internally  developed  drug  candidates,  we  are  actively  seeking 
opportunities to in-license compounds in oncology and other therapeutic areas that are strategic additions 
to  our  product  pipeline.  Such  additional  drug  candidates  could  significantly  increase  our  capital 
requirements  and place further strain on our resources,  including on the time of our existing personnel, 
which  may  delay  or  otherwise  adversely  affect  the  development  of  our  existing  drug  candidates.  As  of 
December 31, 2014, we had 20 full-time employees. We may need to hire more employees as our product 
pipeline and operations expand, further increasing the size of our organization and related expenses. If we 
are unable to manage our growth effectively, we may not efficiently use our resources, which may delay 
the  development  of  our  drug  candidates  and  negatively  impact  our  business,  results  of  operations  and 
financial condition. 

33 

 
We  may  not  be  able  to  attract  and  retain  qualified  personnel  necessary  for  the  development  and 
commercialization  of  our  drug  candidates.  Our  success  may  be  negatively  impacted  if  key  personnel 
leave.

Attracting  and  retaining  qualified  personnel  is  critical  to  our  future  success.  We  compete  for 
qualified  individuals  with  numerous  biopharmaceutical  companies,  universities  and  other  research 
institutions.  Competition  for  such  individuals  is  intense,  and  we  cannot  assure  you  that  we  will  be 
successful in engaging personnel with the skills and experience to support our business and research and 
development activities. 

Our  key  personnel,  especially  Dr.  Chang  H.  Ahn,  our  Chairman  and  Chief  Scientist,  Dr.  Peter 
Suzdak,  our  Chief  Executive  Officer,  and  Dr.  Tae  Heum  Jeong,  our  Chief  Financial  Officer,  provide 
critical technical knowledge and expertise.    The loss of Dr. Ahn, Dr. Suzdak, Dr. Jeong, or any  of  the 
other members of our management team, could result in delays in product development and diversion of 
management resources, which could adversely affect our operating results. We do not have “key person” 
life insurance policies for any of our executive officers. 

Risks Related to Reliance on Third Parties 

Much of our drug development program depends upon third-party researchers, and the results of our 
clinical trials and such research activities are, to a limited extent, beyond our control.

We  have  engaged  third-party  contract  research  organizations  and  other  investigators  and 
collaborators, such as universities and medical institutions, to conduct our pre-clinical studies, toxicology 
studies and clinical trials. Engaging third-party contract research organizations is typical practice in our 
industry. However, relying on such organizations means that the clinical trials and other studies described 
above are being conducted at external locations and that the completion of these trials and studies is not 
within our direct control. Trials and studies may be delayed due to circumstances outside our control, and 
such delays may result in additional expenses for us. 

While  we  make  every  effort  internally  to  oversee  the  work  of  third-party  contractors,  these 
collaborators are not our employees, and we cannot control the effort, time or other resources that they 
devote to our programs. Third parties may not assign priority to our programs or pursue them as diligently 
as we would if we were undertaking them ourselves. If outside collaborators fail to devote sufficient time 
and resources to our drug-development programs, or if their performance is substandard, the approval of 
our FDA applications and introduction of new drugs to the market may be delayed. These collaborators 
may also have relationships with other commercial entities, some of which may compete with us. If our 
collaborators assist our competitors at our expense, our competitive position would be harmed. 

We rely exclusively on third parties to formulate and manufacture our drug candidates, which exposes 
us to a number of risks that may delay development, regulatory approval and commercialization of our 
products or result in higher product costs.

We  have  no  experience  in  drug  formulation  or  manufacturing  and  we  lack  the  resources  and 
expertise  to  formulate  or  manufacture  our  own  drug  candidates  internally.  Therefore,  we  rely  on 
third-party  expertise  to  support  us  in  this  area.  We  have  entered  into  contracts  with  third-party 
manufacturers to manufacture, supply, store and distribute supplies of our drug candidates for our clinical 
trials. If any of our drug candidates receives FDA approval, we expect to rely on third-party contractors to 
manufacture  our  drugs.  We  have  no  current  plans  to  build  internal  manufacturing  capacity  for  any 
product, and we have no long-term supply arrangements. 

34 

 
Our reliance on third-party manufacturers exposes us to the following potential risks: 

(cid:31) We  may  be  unable  to  contract  with  third-party  manufacturers  on  acceptable  terms,  or  at  all, 
because the number of potential manufacturers is limited and is subject to FDA approval. FDA 
approval requires testing and compliance inspections. In addition, any new manufacturer would 
have to be qualified and approved to produce our products after receipt of FDA approval, if any; 

(cid:31) Our  third-party  manufacturers  might  be  unable  to  formulate  and  manufacture  our  drugs  in  the 

volume and of the quality required to meet our clinical and commercial needs, if any; 

(cid:31) Our  third-party  manufacturers  may  not  perform  as  agreed  or  may  not  remain  in  the  contract 
manufacturing business for the time required to supply our clinical trials through completion or to 
successfully produce, store and distribute our commercial products, if approved; 

(cid:31) Drug  manufacturers  are  subject  to  ongoing  periodic  unannounced  inspection  by  the  FDA,  and 
other  government  agencies  to  ensure  compliance  with  cGMP  and  other  government  regulations 
and  corresponding  foreign  standards.  We  do  not  have  control  over  third-party  manufacturers’ 
compliance with these regulations and standards, but we may ultimately be responsible for any of 
their failures; 

(cid:31)

If  any  third-party  manufacturer  makes  improvements  in  the  manufacturing  process  for  our 
products,  we  may  not  own,  or  may  have  to  share,  the  intellectual  property  rights  to  such 
improvements; and 

(cid:31) A  third-party  manufacturer  may  gain  knowledge  from  working  with  us  that  could  be  used  to 

supply one of our competitors with a product that competes with ours. 

Each  of  these  risks  could  delay  or  have  other  adverse  impacts  on  our  clinical  trials  and  the 
approval  and  commercialization  of  our  drug  candidates,  potentially  resulting  in  higher  costs,  reduced 
revenues or both. 

We have no experience selling, marketing or distributing products and currently no internal capability 
to do so.

We currently have no sales, marketing or distribution capabilities. While we intend to have a role 
in  the  commercialization  of  our  products,  we  do  not  anticipate  having  the  resources  in  the  foreseeable 
future  to  develop  global  sales  and  marketing  capabilities  for  all  of  our  proposed  products.  Our  future 
success depends, in part, on our ability to enter into and maintain collaborative relationships with other 
companies  that  have  sales,  marketing  and  distribution  capabilities,  a  strategic  interest  in  the  products 
under  development  and  the  ability  to  successfully  market  and  sell  our  products.  To  the  extent  that  we 
decide  not  to,  or  are  unable  to,  enter  into  collaborative  arrangements  with  respect  to  the  sales  and 
marketing of our proposed products, significant capital expenditures, management resources and time will 
be required to establish and develop an in-house marketing and sales force with the necessary expertise. 
We  cannot  assure  you  that  we  will  be  able  to  establish  or  maintain  relationships  with  third-party 
collaborators or develop in-house sales and distribution capabilities. To the extent that we depend on third 
parties for marketing and distribution, any revenues we receive will depend upon the efforts of such third 
parties, as well as the terms of our agreements with such third parties, which cannot be predicted at this 
early stage of our development. We cannot assure you that such efforts will be successful. In addition, we 
cannot assure you that we will be able to market and sell our products in the United States or overseas. 

35 

 
We may incur substantial liabilities and may be required to limit commercialization of our products in 
response to product liability lawsuits.

The testing and marketing of medical products entail an inherent risk of product liability. Product 
liability claims may be brought against us by subjects enrolled in our clinical trials, patients, healthcare 
providers or others using, administering or selling our products. Large judgments have been awarded in 
class action lawsuits based on drugs that had unanticipated side effects. If we cannot successfully defend 
ourselves  against  product  liability  claims,  we  may  incur  substantial  liabilities  or  be  required  to  limit 
commercialization  of  our  products.  Our  inability  to  obtain  sufficient  product  liability  insurance  at  an 
acceptable  cost  to  protect  against  potential  product  liability  claims  could  prevent  or  inhibit  the 
commercialization  of  pharmaceutical  products  we  develop,  alone  or  with  collaborators.  Although  we 
currently carry clinical trial insurance and product liability insurance we, or any collaborators, may not be 
able to maintain such insurance at a reasonable cost. Even if our agreements with any future collaborators 
entitle us to indemnification against losses, such indemnification may not be available or adequate should 
any claims arise. 

Risks Related to Our Intellectual Property 

If we breach the license agreements for our product candidates, we could lose the ability to continue 
the development and commercialization of our product candidates. 

We  do  not  own  the  rights  to  the  intellectual  property  underlying  Serdaxin  and  Zoraxel.    Our 
rights to these product candidates have been granted by third parties pursuant to license agreements.    If 
we  fail  to  meet  our  obligations  under  these  license  agreements  or  otherwise  breach  the  agreements,  we 
may  lose  our  exclusive  rights,  which may  result  in  a  complete  termination  of  our  product development 
and any commercialization efforts for the applicable product candidate. 

If we fail to adequately protect or enforce our intellectual property rights or secure rights to patents of 
others, the value of our intellectual property rights would diminish, and our business and competitive 
position would suffer.

Our success, competitive position and future revenues will depend in part on our ability and the 
abilities of our licensors and licensees to obtain and maintain patent protection for our products, methods, 
processes and other technologies, to preserve our trade secrets, to prevent third parties from infringing on 
our proprietary rights and to operate without infringing the proprietary rights of third parties. We have an 
active patent protection program that includes filing patent applications on new compounds, formulations, 
delivery systems and methods of making and using products and prosecuting these patent applications in 
the  United  States  and  abroad.  As  patents  issue,  we  also  file  continuation  applications  as  appropriate. 
Although we have taken steps to build a strong patent portfolio, we cannot predict: 

(cid:31)

(cid:31)

the  degree  and  range  of  protection  any  patents  will  afford  us  against  competitors,  including 
whether third parties find ways to invalidate or otherwise circumvent our licensed patents; 

if and when patents will issue in the United States or any other country; 

(cid:31) whether or not others will obtain patents claiming aspects similar to those covered by our licensed 

patents and patent applications; 

(cid:31) whether we will need to initiate litigation or administrative proceedings to protect our intellectual 

36 

 
 
property rights, which may be costly whether we win or lose; 

(cid:31) whether  any  of  our  patents  will  be  challenged  by  our  competitors  alleging  invalidity  or 
unenforceability and, if opposed or litigated, the outcome of any administrative or court action as 
to patent validity, enforceability or scope; 

(cid:31) whether  a  competitor  will  develop  a  similar  compound  that  is  outside  the  scope  of  protection 
afforded  by  a  patent  or  whether  the  patent  scope  is  inherent  in  the  claims  modified  due  to 
interpretation of claim scope by a court; 

(cid:31) whether  there  were  activities  previously  undertaken  by  a  licensor  that  could  limit  the  scope, 

validity or enforceability of licensed patents and intellectual property; or 

(cid:31) whether  a  competitor  will  assert  infringement  of  its  patents  or  intellectual  property,  whether  or 

not meritorious, and what the outcome of any related litigation or challenge may be. 

Our  success  also  depends  upon  the  skills,  knowledge  and  experience  of  our  scientific  and 
technical  personnel, our consultants and advisors  as  well as our licensors, sublicensees and contractors. 
To help protect our proprietary know-how and our inventions for which patents may be unobtainable or 
difficult  to  obtain,  we  rely  on  trade  secret  protection  and  confidentiality  agreements.  To  this  end,  we 
require all employees to enter into agreements that prohibit the disclosure of confidential information and, 
where  applicable,  require  disclosure  and  assignment  to  us  of  the  ideas,  developments,  discoveries  and 
inventions important to our business. These agreements may not provide adequate protection for our trade 
secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure or 
the  lawful  development  by  others  of  such  information.  If  any  of  our  trade  secrets,  know-how  or  other 
proprietary information is disclosed, the value of our trade secrets, know-how and other proprietary rights 
would be significantly impaired, and our business and competitive position would suffer. 

Due to legal and factual uncertainties regarding the scope and protection afforded by patents and other 
proprietary rights, we may not have meaningful protection from competition.

 Our  long-term  success  will  substantially  depend  upon  our  ability  to  protect  our  proprietary 
technologies  from  infringement,  misappropriation,  discovery  and  duplication  and  avoid  infringing  the 
proprietary  rights  of  others.  Our  patent  rights,  and  the  patent  rights  of  biopharmaceutical  companies  in 
general, are highly uncertain and include complex legal and factual issues. These uncertainties also mean 
that any patents that we own or may obtain in the future could be subject to challenge, and even if not 
challenged, may not provide us with meaningful protection from competition. Patents already issued to us 
or our pending applications may become subject to dispute, and any dispute could be resolved against us. 

In  connection  with  the  process  of  seeking  patent  protection  for  Supinoxin  in  Japan,  we  filed  a 
patent  application  including  claims  covering  Supinoxin  with  the  Japanese  Patent  Office  (“JPO”)  for 
examination.  The  JPO  initially  agreed  that  the  claims  covering  the  compound  for  Supinoxin  were 
allowable, but as a result of a mistake in the patent application filing as prepared and submitted by our 
Japanese patent attorneys and incomplete review by the JPO’s patent examiner, the JPO issued a decision 
to grant a patent with claims that did not include Supinoxin.   We appealed this decision with the JPO to 
request  withdrawal  of  the  decision  to  grant  so  that  the  correct  claims  would  be  allowed,  but  the  JPO 
refused  to  withdraw  its  decision. As  a  result,  and  in  accordance  with  Japanese  law  and  procedure  for 
appealing patent application decisions, we have filed a lawsuit against the JPO in Tokyo District Court to 
cause the JPO to reverse its decision to grant the errant patent and to allow a patent that includes claims 
covering  Supinoxin.   The  patent  application  at  issue  remains  pending  subject  to  the  outcome  of  this 

37 

 
action. There can be no guarantee that we will be successful in winning the appeal to correct the error in 
the patent registration that would exclude the compound for Supinoxin. 

If we infringe the rights of third parties, we could be prevented from selling products and be forced to 
defend against litigation and pay damages.

If our products, methods, processes and other technologies infringe the proprietary rights of other 

parties, we could incur substantial costs and may have to:     

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

obtain licenses, which may not be available on commercially reasonable terms, if at all; 

redesign our products or processes to avoid infringement; 

stop using the subject matter claimed in patents held by others, which could cause us to lose the 
use of one or more of our drug candidates; 

pay damages; or 

defend  litigation  or  administrative  proceedings  that  may  be  costly  whether  we  win  or  lose  and 
that could result in a substantial diversion of our management resources. 

Although we have not received any claims of infringement by any third parties to date, we expect 
that as our drug candidates move further into clinical trials and commercialization and our public profile 
is raised, we may be subject to such claims. 

Risks Related to Ownership of Our Common Stock 

An investment in shares  of our common stock is very speculative and involves a very high degree of 
risk.

To  date,  we  have  generated  no  revenues  from  product  sales  and  only  minimal  revenues  from  a 
research  agreement  with  a  minority  shareholder  and  interest  on  bank  account  balances  and  short-term 
investments.  Our  accumulated  deficit  as  of  December  31,  2014  and  2013  was  $91,332,308  and 
$72,810,707,  respectively.  For  the  years  ended  December  31,  2014,  and  2013,  we  had  net  losses  of 
$18,521,601  and  $9,499,424,  respectively,  partially  as  a  result  of  expenses  incurred  through  a 
combination of research and development activities related to the various technologies under our control 
and expenses supporting those activities. Until we receive approval from the FDA and other regulatory 
authorities for our drug candidates, we cannot sell our drugs and will not have product revenues. 

The market price of our common stock may fluctuate significantly.

The market price of our common stock may fluctuate significantly in response to factors, some of 

which are beyond our control, such as: 

(cid:31)

(cid:31)

(cid:31)

the announcement of new products or product enhancements by us or our competitors; 

changes in our relationships with our licensors or other strategic partners; 

developments concerning intellectual property rights and regulatory approvals; 

38 

 
(cid:31)

(cid:31)

(cid:31)

(cid:31)

variations in our and our competitors’ results of operations; 

changes in earnings estimates or recommendations by securities analysts;   

changes in the structure of healthcare payment systems; and 

developments and market conditions in the pharmaceutical and biotechnology industries. 

Further, the stock market, in general, and the market for biotechnology companies, in particular, 
have  experienced  extreme  price  and  volume  fluctuations.  Continued  market  fluctuations  could  result  in 
extreme volatility in the price of our common stock, which may be unrelated or disproportionate to our 
operating performance and which could cause a decline in the value of our common stock. You should 
also be aware that price volatility might be worse if the trading volume of our common stock is low.   

We will require additional capital funding the receipt of which may impair the value of our common 
stock.

Our  future  capital  requirements  depend  on  many  factors,  including  our  research,  development, 
sales and marketing activities. We will need to raise additional capital through public or private equity or 
debt  offerings  or  through  arrangements  with  strategic  partners  or  other  sources  in  order  to  continue  to 
develop our drug candidates.    There can be no assurance that additional capital will be available when 
needed or on terms satisfactory to us, if at all.  To the extent we raise additional capital by issuing equity 
securities, our stockholders may experience substantial dilution and the new equity securities may have 
greater rights, preferences or privileges than our existing common stock. 

We have not paid dividends to our stockholders in the past, and we do not anticipate paying dividends 
to our stockholders in the foreseeable future.

We have not declared or paid cash dividends on our common stock. We currently intend to retain 
all  future  earnings,  if  any,  to  fund  the  continuing  operation  of  our  business,  and  therefore  we  do  not 
anticipate  paying  dividends  on  our  common  stock  in  the  foreseeable  future.  As  a  result,  you  will  not 
realize  any  income  from  an  investment  in our  common  stock  until  and  unless  you  sell your  shares  at  a 
profit. 

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

The market price of our common stock may be volatile, and in the past companies that have 

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

described herein or implied by such forward-looking statements. 

OVERVIEW

We are a clinical stage biopharmaceutical company dedicated to the discovery, development and 
commercialization of innovative treatments for cancer and other medical needs. Our pipeline features one 
oncology candidate in Phase II clinical trials, two oncology candidates in Phase I clinical trials, and other 
drug  candidates  in  pre-clinical  development.  Our  strategy  is  to  continue  building  a  significant  product 
pipeline of innovative medicines that we will commercialize alone or with pharmaceutical partners. 

Since  our  inception,  our  operations  have  been  limited  to  organizing  and  staffing  the  Company, 
acquiring,  developing,  and  securing  our  proprietary 
technology,  drug  candidate  research  and 
development, and undertaking, through third parties, pre-clinical and clinical trials of our principal drug 
candidates.  As a clinical stage company, we have no product sales to date, and we will not generate any 
product sales until we receive approval from FDA or equivalent foreign regulatory bodies to begin selling 
our pharmaceutical candidates.  Our  major sources of working capital have been proceeds from various 
private  financings,  primarily  private  sales  of  common  stock  and  debt  securities  and  collaboration 
agreements with our strategic investors. 

Critical Accounting Policies 

A  “critical  accounting  policy”  is  one  which  is  both  important  to  the  portrayal  of  our  financial 
condition  and  results  and  requires  our  management’s  most  difficult,  subjective  or  complex  judgments, 
often as a result of the need to make estimates about the effect of matters that are inherently uncertain.   
Our  accounting  policies  are  in  accordance  with  U.S.  generally  accepted  accounting  principles  and  their 
basis  of  application  is  consistent  with  that  of  the  previous  year.    Our  significant  estimates  include 
assumptions  made  in  estimating  the  fair  values  of  stock-based  compensation,  warrant  liabilities, 
marketable  securities,  and  our  assessment  relating  to  costs  incurred  on  research  and  development 
contracts.   

Research and Development 

Research and development costs are expensed as incurred.    Research and development expenses 
consist  primarily  of  third  party  service  costs  under  research  and  development  agreements,  salaries  and 
related  personnel  costs,  as  well  as  stock  compensation  related  to  these  costs,  costs  to  acquire 
pharmaceutical  products  and  product  rights  for  development  and  amounts  paid  to  contract  research 
organizations, hospitals and laboratories for the provision of services and materials for drug development 
and clinical trials. 

Costs incurred in obtaining the license rights to technology in the research and development stage 

42 

 
that have no alternative future uses and are for unapproved product compounds are expensed as incurred. 

Fair Value of Financial Instruments 

The  carrying  amounts  reported  in  the  accompanying  financial  statements  for  cash  and  cash 
equivalents,  prepaid  expenses  and  other  current  assets  and  accounts  payable  and  accrued  expenses 
approximate fair value because of the short-term maturity of these financial instruments.    The fair value 
methodology for our warrant liabilities and marketable securities is described in detail in Item 8 of this 
Annual Report on Form 10-K. 

Income Taxes 

We  account  for  income  taxes  in  accordance  with  Accounting  Standards  Codification  (“ASC”) 
740,  “Income  Taxes.”    Deferred  tax  assets  and  liabilities  are  recorded  for  differences  between  the 
financial  statement  and  tax  basis  of  the  assets  and  liabilities  that  will  result  in  taxable  or  deductible 
amounts in the future based on enacted tax laws and rates.    ASC 740 requires that a valuation allowance 
be established when it is more likely than not that all portions of a deferred tax asset will not be realized.   
A review of all positive and negative evidence needs to be considered, including a company’s current and 
past  performance,  the  market  environment  in  which  the  company  operates,  length  of  carryback  and 
carryforward  periods  and  existing  contracts  that  will  result  in  future  profits.    Income  tax  expense  is 
recorded for the amount of income tax payable or refundable for the period, increased or decreased by the 
change in deferred tax assets and liabilities during the period. 

As a result of our significant cumulative losses, we determined that it was appropriate to establish 

a valuation allowance for the full amount of our deferred tax assets. 

The  calculation  of  our  tax  liabilities  involves  the  inherent  uncertainty  associated  with  the 
application  of  complex  tax  laws.    We  are  subject  to  examination  by  various  taxing  authorities.    We 
believe that as a result of our losses sustained to date, any examination would result in a reduction of our 
net operating loss carryforward rather than a tax liability.    As such, we have not provided for additional 
taxes estimated under ASC 740.   

Warrant Liabilities 

In  accordance  with  ASC  480,  “Distinguishing  Liabilities  from  Equity,”  we  record  warrant 
liabilities at fair value due to provisions in our warrant agreements, as discussed in Footnote 12 of Item 8 
of  this  Annual  Report  on  Form  10-K.    We  reevaluate  the  fair  value  of  our  warrants  at  each  reporting 
period,  and  changes  in  the  fair  value  between  reporting  periods  is  recorded  as  “unrealized  loss  on  fair 
value of warrants” in the statement of operations.     

Stock-Based Compensation 

In accordance with ASC 718, “Stock Compensation” compensation costs related to share-based 
payment transactions, including employee stock options, are to be recognized in the financial statements. In 
addition, we adhere to the guidance set forth within SEC Staff Accounting Bulletin No. 107 (“SAB 107”), 
which provides the Staff’s views regarding the interaction between ASC 718 and certain SEC rules and 
regulations, and provides interpretations with respect to the valuation of share-based payments for public 
companies.   

Concentration of Credit Risk 

ASC 825, “Financial Instruments,” requires disclosure of any significant off-balance sheet risk and 
credit risk concentration.    We do not have significant off-balance sheet risk or credit concentration.    We 
maintain cash and short-term investments with major financial institutions.    From time to time we have 
funds on deposit with commercial banks that exceed federally insured limits.    The balances are insured by 
the  Federal  Deposit  Insurance  Corporation  up  to  $250,000.  At  December  31,  2014,  our  uninsured  cash 

43 

 
balance was $7,671,892. Management does not consider this to be a significant credit risk as the banks are 
large, established financial institutions. 

Recently Issued Accounting Standards

In  June  2014,  the  Financial  Accounting  Standards  Board  (the  “FASB”)  issued  Accounting 
Standards  Update  (“ASU”)  2014-10,  “Development  Stage  Entities:  Elimination  of  Certain  Financial 
Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, 
Consolidation.”    ASU  2014-10  eliminates  several  of  the  reporting  requirements  for  development  stage 
entities, including the requirement to present inception to date information in the statements of income, 
comprehensive income, cash flows, and shareholder equity, and to label the financial statements as those 
of  a  development  stage  entity.    ASU  2014-10  also  clarifies  that  the  guidance  in  Accounting  Standards 
Codification  (“ASC”)  Topic  275,  “Risks  and  Uncertainties”,  is  applicable  to  entities  that  have  not 
commenced  principal  operations,  and  eliminates  an  exception  to  the  sufficiency-of-equity  risk  criterion 
for development stage entities, and will require all reporting entities that have an interest in development 
stage enterprises to apply consistent consolidation guidance for variable interest entities. ASU 2014-10 is 
effective  for  all  annual  reporting  periods  beginning  after  December  15,  2014,  with  early  adoption 
permitted.    We  adopted  ASU  2014-10  during  the  year  ended  December  31,  2014,  and  removed  the 
incremental reporting requirements for development stage entities. 

In  May  2014,  the  FASB  issued  ASU  2014-09,  “Revenue  from  Contracts  with  Customers”,  a 
comprehensive  new  revenue  recognition  standard  that  will  supersede  nearly  all  existing  revenue 
recognition  guidance  under  US  Generally  Accepted  Accounting  Principles.    The  standard’s  core 
principle is that a company should recognize revenue when it transfers goods or services to customers in 
an  amount  that  reflects  the  consideration  to  which  the  company  expects  to  be  entitled  in  exchange  for 
those  goods  and  services,  and  provides  a  revenue  recognition  framework  in  accordance  with  this 
principle.    ASU  2014-09  is  effective  for  annual  reporting  periods  beginning  after  December  15,  2016 
and interim periods therein.    We are currently evaluating the impact that the adoption of this guidance 
will have on our financial statements and future operating results. 

In  August  2014,  the  FASB  issued  ASU  2014-15:  Disclosure  of  Uncertainties  about  an  Entity’s 
Ability  to  Continue  as  a  Going  Concern,  which  requires  management  to  perform  interim  and  annual 
assessments  as  to  the  entity’s  ability  to  continue  as  a  going  concern  and  provides  related  disclosure 
guidance.    ASU 2014-15 will be effective for reporting periods beginning after December 15, 2016, with 
early adoption permitted. We are currently evaluating the impact the adoption of this guidance will have 
on its financial statements.     

Results of Operations

Comparison of the Years Ended December 31, 2014 and December 31, 2013 

Total Revenues 

We had no revenues for the years ended December 31, 2014 or 2013. 

General and Administrative Expenses 

General  and  administrative  expenses  consist  primarily  of  salaries  and  related  expenses  for 
executive, finance and other administrative personnel, recruitment expenses, professional fees and other 
corporate expenses, including business development, investor relations, and general legal activities. 

44 

 
General  and  administrative  expenses  increased  $1,527,629,  or  32.3%,  to  $6,253,328  for  the  year  ended 
December  31,  2014  from  $4,725,699  for  the  year  ended  December  31,  2013.      The  year  over  year 
increase  is  primarily  attributable  to  an  increase  in  professional  fees  and  personnel  expenses.   
Professional fees increased approximately $1,015,000 during the year ended December 31, 2014 due to 
increased  legal  and  accounting  fees  regarding  corporate  organizational  matters,  consulting,  proxy 
solicitation fees, and investor relations fees and compensatory stock.    For the year ended December 31, 
2014, general and administrative expenses also increased approximately $175,000 due to an increase in 
personnel, and $150,000 due to an increase in insurance coverage. 

Research and Development Expenses 

Research and development expenses consist primarily of salaries and related personnel costs, fees 
paid to consultants and outside service providers for laboratory development and other expenses relating 
to the design, development, testing, and enhancement of our drug candidates.    We expense our research 
and development costs as they are incurred. 

Research and development expenses increased $3,762,762, or 115.7%, to $7,015,901 for the year 
ended  December  31  2014,  from  $3,253,139  for  the  year  ended  December  31,  2013.    The  increase  is 
primarily attributable to the advancement of our drug candidates.    During the year ended December 31, 
2014,  one  of  our  drug  candidates,  Archexin,  entered  a  Phase  IIa  clinical  trial  to  study  its  safety  and 
efficacy in patients with metastatic renal cell carcinoma (“RCC”) and another drug candidate, RX-3117, 
entered a Phase Ib clinical trial to study its safety and efficacy in patients with solid tumors. Our Phase I 
trial for Supinoxin was initiated in August 2013 and continued through 2014. Research and development 
personnel and overhead increased due to the hiring of additional personnel. 

The  table  below  summarizes  the  approximate  amounts  spent  on  each  of  our  research  and 

development projects for the years ended December 31, 2014 and 2013:

Interest income increased $84,627, or 171.7% to $133,907 for the year ended December 31, 2014 
from  $49,280  for  the  year  ended  December  31,  2013.    The  increase  is  primarily  attributable  to  higher 
cash  and  cash  equivalents  and  marketable  securities  balances  due  to  our  registered  direct  offering  in 
January 2014 and the exercise of warrants in 2014. 

45 

 
     
Unrealized Loss on Fair Value of Warrants 

Our warrants are recorded as liabilities at fair value, and the warrants are valued using a lattice 
model.    Changes in the fair value of warrants are recorded as an unrealized gain or loss in our statement 
of operations.    During the years ended December 31, 2014 and 2013, we recorded unrealized losses on 
the  fair  value  of  our  warrants  of  $5,180,107  and  $1,365,654,  respectively.    Estimating  fair  values  of 
warrants  requires  the  development  of  significant  and  subjective  estimates  that  may,  and  are  likely  to, 
change  over  the  duration  of  the  warrant  with  related  changes  to  external  market  factors.  The  large 
unrealized loss for the year ended December 31, 2014 primarily resulted from an increased stock price of 
the  underlying  common  stock  at  December  31,  2014  and  on  the  dates  in  2014  when  warrant  holders 
exercised their warrants.   

Financing Expense 

We incurred $206,172 and $204,212 of financing expenses during the years ended December 31, 
2014 and 2013, respectively, related to our registered direct offerings in January 2014, October, 2013 and 
July 2013.     

Net Loss 

As  a  result  of  the  above,  net  loss  for  the  years  ended  December  31,  2014  and  2013  was 

$18,521,601 and $9,499,424 or $0.11 and $0.07 per share, respectively. 

Research and Development Projects 

Research  and  development  costs  are  expensed  as  incurred.  These  costs  consist  primarily  of 
salaries  and  related  personnel  costs,  costs  to  acquire  pharmaceutical  products  and  product  rights  for 
development  and  amounts  paid  to  contract  research  organizations,  hospitals  and  laboratories  for  the 
provision of services and materials for drug development and clinical trials.  Costs incurred in obtaining 
the license rights to technology in the research and development stage that have no alternative future uses 
are  expensed  as  incurred.  Our  research  and  development  programs  are  related  to  our  oncology  clinical 
stage  drug  candidates,  Archexin,  RX-3117  and  Supinoxin,  and  our  pre-clinical  stage  drug  candidates, 
Archexin-Nano  and  RX-21101.  As  we  expand  our  clinical  studies,  we  will  enter  into  additional 
development agreements.  Significant additional expenditures will be required if we complete our clinical 
trials, start new trials, apply for regulatory approvals, continue development of our technologies, expand 
our operations and bring our products to market.  The eventual total cost of each clinical trial is dependent 
on a number of uncertainties such as trial design, the length of the trial, the number of clinical sites and 
the  number  of  patients.  The  process  of  obtaining  and  maintaining  regulatory  approvals  for  new 
therapeutic  products  is  lengthy,  expensive  and  uncertain.  Because  the  successful  development  of  our 
most  advanced  drug  candidates,  Archexin,  RX-3117  and  Supinoxin,  is  uncertain,  and  because 
Archexin-Nano,  and  RX-21101  are  in  early-stage  development,  we  are  unable  to  estimate  the  costs  of 
completing our research and development programs, the timing of bringing such programs to market and, 
therefore, when material cash inflows could commence from the sale of these drug candidates, if any.  If 
these  projects  are  not  completed  as  planned,  our  results  of  operations  and  financial  condition  would be 
negatively affected.   

Archexin®

Archexin is a potential best-in-class, potent inhibitor of the protein kinase phosphorylated Akt-1, 
which  is  over-expressed  in  cancer  cells  and  which  we  believe  plays  a  critical  role  in  cancer  cell 

46 

 
proliferation, survival, angiogenesis, metastasis and drug resistance.  Archexin has received “orphan drug” 
designation from the FDA, for RCC, glioblastoma, ovarian cancer, stomach cancer and pancreatic cancer.   
That designation provides tax incentives for clinical research and a waiver of user fees.    In addition, a drug 
that is approved for its orphan-designated use receives seven years of exclusivity after approval, during 
which  the  FDA  generally  cannot  approve  another  product  with  the  same  active  moiety  for  the  same 
indication.   

  In August 2012, we announced top line results of an open label 2-stage Phase IIa clinical trial for 
Archexin that was designed to assess the safety and efficacy of Archexin in combination with gemcitabine.   
Gemcitabine is used to treat pancreatic, breast, ovarian and lung cancers.    Gemcitabine is a member of a 
group of chemotherapy drugs known as anti-metabolites.    It prevents cells from making DNA and RNA, 
which stops cell growth and causes cells to die.    Stage 1 was the dose-finding portion of the study, and 
Stage 2 was the dose-expansion portion of the study using the dose identified in Stage 1 administered with 
gemcitabine.      The  study  enrolled  31  subjects  aged  18  to  65  with  metastatic  pancreatic  cancer  at  nine 
centers in the United States and India.    The primary endpoint was overall survival following four cycles of 
therapy with a six month follow-up.    For those evaluable patients, the study demonstrated that treatment 
with Archexin in combination with gemcitabine provided a median survival rate of 9.1 months compared to 
the  historical  survival  data  of  5.65  months  for  standard  single  agent  gemcitabine  therapy.    The  most 
frequent  reported  adverse  events  were  constipation,  nausea,  abdominal  pain  and  pyrexia,  regardless  of 
relatedness.   

We initiated a Phase IIa clinical proof-of-concept clinical trial of Archexin in January 2014 to study 
its  safety  and  efficacy  in  patients  with  metastatic  RCC.  In  the  trial,  Archexin  will  be  administered  in 
combination with everolimus (Afinitor®), and will be conducted in two stages.    The first stage will be dose 
ranging, with up to three dose groups with three RCC patients each, to determine its maximal tolerated dose 
(“MTD”) in combination with everolimus.    Once the MTD has been determined, thirty RCC patients will 
be randomized to either Archexin in combination with everolimus or everolimus alone, in a ratio of 2:1.   
Rexahn plans to complete the initial safety component of this study in the second half of 2015.    We expect 
that expenses related to Archexin will increase in 2015 compared to 2014 as we carry out the Phase IIa 
clinical trial.     

RX-3117 

  RX-3117  is  a  small  molecule  nucleoside  compound  with  an  anti-metabolite  mechanism  of 
action, and we believe it has therapeutic potential in a broad range of cancers including colon, lung, and 
pancreatic  cancer.    RX-3117  has  received  orphan  drug  designation  for  the  treatment  of  patients  with 
pancreatic  cancer.    RX-3117  has  also  been  shown  to  be  effective  in  inhibiting  the  growth  of 
gemcitabine-resistant  human  cancers  and  in  improving  overall  survival  in  pre-clinical  animal  models.   
We  completed  an  exploratory  Phase  I  clinical  study  of  RX-3117  in  2012  that  demonstrated  the  oral 
bioavailability of RX-3117 in humans with no adverse effects reported in the study.       

In  January  2014,  we  initiated  a  Phase  Ib  clinical  trial  to  study  the  safety,  tolerability, 
dose-limiting toxicities and MTD of RX-3117 in patients with solid tumors.    Secondary endpoints will 
include characterizing the pharmacokinetic profile of RX-3117 and evaluating the preliminary anti-tumor 
effects of RX-3117.    Patient enrollment has been completed in eight dose groups (30mg, 60mg, 100mg, 
150mg,  200mg,  500mg,  1,000mg  and  1,500mg).  The MTD of RX-3117 has not yet been achieved. We 
expect  to  complete  patient  enrollment  in  the  first  half  of  2015.    RX-3117  continues  to  preliminarily 
demonstrate safety and tolerability, requiring higher dose levels than expected to be tested to achieve the 
MTD.    To date, no dose-limiting toxicities have been associated with RX-3117 treatment.    Based on the 
progress of the RX-3117 clinical development program and the level of interest expressed from a number of 
oncology-focused  pharmaceutical  companies,  Rexahn  is  continuing  its  discussions  with  multiple 

47 

 
companies to explore collaborative business structures in an effort to maximize the potential upside value 
of the program.    We expect that expenses related to RX-3117 will increase in 2015 compared to 2014 as 
we carry out the Phase I trial and continue to seek collaboration partners. 

Supinoxin (RX-5902) 

Supinoxin  is  a  potential  first-in-class  small  molecule  that  inhibits  the  phosphorylation  of  p68 
RNA  helicase,  a  protein  that  we  believe  plays  a key  role  in  cancer  growth,  progression  and  metastasis. 
Phosphorylated  p68,  which  is  highly  expressed  in  cancer  cells,  but  not  in  normal  cells,  results  in 
up-regulation  of  cancer-related  genes  and  a  subsequent  proliferation  or  tumor  growth  of  cancer  cells.   
Supinoxin selectively blocks phosphorylated p68, thereby decreasing the proliferation or growth of cancer 
cells.    In  pre-clinical  tissue  culture  models  and  in-vivo  xenograft  models,  Supinoxin  has  demonstrated 
single-agent tumor growth inhibition synergism with cytotoxic agents and activity against drug resistant 
cancer cells.    In particular, in in-vivo xenograft models of human RCC and pancreatic cancer, treatment 
with Supinoxin on days 1 to 20 in mouse models produced a survival benefit beyond 65 days.     

In  July  2012,  we  submitted  an  investigational  new  drug  application,  or  IND,  to  the  FDA  for 
Supinoxin. We initiated a Phase I clinical trial in August 2013 to study Supinoxin’s safety and efficacy in 
patients with solid tumors.    Patients in seven dose groups (25mg, 50mg, 100mg, 150mg, 225mg, 300mg 
and 425mg) have been enrolled and the MTD of Supinoxin has not yet been reached.    Depending on the 
number of dose groups needed to determine the MTD, we expect to complete this trial in the first half of 
2015.    Supinoxin  continues  to  preliminarily  demonstrate  safety  and  tolerability,  requiring  higher  dose 
levels than expected to achieve the MTD.    Based on the progress of the Supinoxin clinical development 
program and the level of interest expressed from a number of oncology-focused pharmaceutical companies, 
Rexahn is continuing its discussions with multiple companies to explore collaborative business structures in 
an  effort  to  maximize  the  potential  upside  value  of  the  program.    We  expect  that  expenses  related  to 
Supinoxin will increase in 2015 compared to 2014 as we complete the Phase I clinical trial and continue 
development.   

Pre-clinical Pipeline 

Archexin-Nano  and  RX-21101  are  in  a  pre-clinical  stage  of  development.    We  expect  that 
expenses related to our pre-clinical candidates will remain flat in 2015 compared to 2014 as we continue 
research and development efforts related to these candidates. 

Research and Development Process

We  have  engaged  third-party  contract  research  organizations  and  other  investigators  and 
collaborators, such as universities and medical institutions, to conduct our pre-clinical studies, toxicology 
studies and clinical trials.    Engaging third-party contract research organizations is typical practice in our 
industry. However, relying on such organizations means that the clinical trials and other studies described 
above are being conducted at external locations and that the completion of these trials and studies is not 
within our direct control. Trials and studies may be delayed due to circumstances outside our control, and 
such delays may result in additional expenses for us. 

Liquidity and Capital Resources

Cash Flows 

Cash used in operating activities was $11,041,211 for the year ended December 31, 2014.    The 
operating cash flows during the year ended December 31, 2014 reflect our net loss of $18,521,601, which 

48 

 
includes an unrealized loss on fair value of warrants of $5,180,107 and a net increase of cash components 
of  working  capital  and  other  non-cash  charges  totaling  $2,300,283.    Cash  used  in  operating  activities 
was $7,984,856 for the year ended December 31, 2013, which reflects our net loss of $9,499,424 and a 
net increase of cash components of working capital and non-cash charges totaling $1,514,568. 

Cash used in investing activities was $22,661,045 for the year ended December 31, 2014, which 
consisted  of  $26,075,926  and  $41,249  for  the  purchases  of  marketable  securities  and  equipment, 
respectively,  offset  by  a  decrease  in  restricted  cash  equivalents  of  $196,130  and  $3,260,000  from  the 
redemption of marketable securities.    Cash provided by investing activities for the year ended December 
31, 2013 was $845,522, which consisted of a decrease in restricted cash equivalents of $895,671, offset 
by $50,149 for the purchase of equipment.   

Cash  provided  by  financing  activities  was  $24,840,470  for  the  year  ended  December  31,  2014, 
which  consisted  of  net  proceeds  of  $18,634,247  from  our  registered  direct  public  offering  in  January 
2014, $258,955 from the exercise of stock options and $5,947,268 from the exercise of warrants.    Cash 
provided by financing activities was $12,340,822 for the year ended December 31, 2013, which consisted 
of  net  proceeds  of  $10,041,155  from  our  registered  direct  public  offerings  in  July  and  October,  2013, 
$90,000 from the exercise of stock options, and $2,209,667 from the exercise of warrants. 

Financings

On  July  26,  2013  we  closed  on  a  registered  direct  public  offering  to  issue  and  sell  11,400,000 
shares  of  common  stock  and  warrants  to  purchase  up  to  3,990,000  shares  of  common  stock.    The 
common  stock  and  warrants  were  sold  in  units,  consisting  of  common  stock  and  a  warrant  to  purchase 
0.35  shares  of  common  stock,  at  a  price  of  $0.50  per  unit,  and  the  warrants  have  an  exercise  price  of 
$0.59  per  share.    The  total  gross  proceeds  of  the  offering  were  $5,700,000.    The  warrants  issued  are 
exercisable beginning six months after the closing date until the five-year anniversary of the closing date. 

On October 16, 2013 we closed on a registered direct public offering to issue and sell 10,192,309 
shares  of  common  stock  and  warrants  to  purchase  up  to  3,567,309  shares  of  common  stock.    The 
common  stock  and  warrants  were  sold  in  units,  consisting  of  common  stock  and  a  warrant  to  purchase 
0.35  shares  of  common  stock,  at  a  price  of  $0.52  per  unit,  and  the  warrants  have  an  exercise  price  of 
$0.575 per share.    The total gross proceeds of the offering were $5,300,001.    The warrants issued are 
exercisable beginning six months after the closing date until the five-year anniversary of the closing date. 

On January 21, 2014 we closed on a registered direct public offering to issue and sell 19,047,620 
shares  of  common  stock  and  warrants  to  purchase  up  to  4,761,905  shares  of  common  stock.    The 
common  stock  and  warrants  were  sold  in  units,  consisting  of  common  stock  and  a  warrant  to  purchase 
0.25  shares  of  common  stock,  at  a  price  of  $1.05  per  unit,  and  the  warrants  have  an  exercise  price  of 
$1.28 per share.    The total gross proceeds of the offering were $20,000,001.    The warrants issued are 
exercisable beginning six months and one day after the closing date until the five-year anniversary of the 
closing date. 

We  will  need  to  raise  additional  capital  through  public  or  private  equity  or  debt  offerings  or 
through  arrangements  with  strategic  partners  or  other  sources  in  order  to  continue  to  develop  our  drug 
candidates.    There can be no assurance that additional capital will be available when needed or on terms 
satisfactory to us, if at all.  If we are not able to raise sufficient additional capital, we will have to reduce 
our  research  and  development  activities. We  will  first  reduce  research  and  development  activities 
associated  with  our  pre-clinical  compounds.  To  the  extent  necessary,  we  will  then  reduce  our  research 
and development activities related to some or all of our clinical drugs.

At Market Issuance Sales Agreement 

On  March  16,  2015,  we  entered  into  an  at  market  issuance  sales  agreement  (the  “Sales 
Agreement”)  with  MLV  &  Co.  LLC  (“MLV”),  pursuant  to  which  we  may  issue  and  sell  shares  of  our 
common stock having an aggregate offering price of up to $40 million from time to time, at our option, 
through MLV as our sales agent, subject to certain terms and conditions. Upon our delivery and MLV’s 
acceptance of a placement notice, MLV will use commercially reasonable efforts to sell shares, consistent 
with  its  normal  trading  and  sales  practices,  in  transactions  deemed  to  be  “at  the  market”  offerings  as 
defined in Rule 415 of the Securities Act of 1933, as amended, including by means of ordinary brokers’ 
transactions at market prices, in block transactions or as otherwise agreed by MLV and us. MLV may also 
sell the shares of common stock in negotiated transactions, subject to our prior approval. Any shares sold 
will be sold pursuant to our effective shelf registration statement on Form S-3 (File No. 333-196255), as 
supplemented  by  a  prospectus  supplement  dated  March  16,  2015.  We  will  pay  MLV  a  commission  of 
3.0% of the gross proceeds of the sale of any shares sold through MLV. To date, no shares have been sold 
under the Sales Agreement. We are not obligated to make any sales under the Sales Agreement and no 
assurance can be given that we will sell any shares under the Sales Agreement, or, if we do, as to the price 
or  amount  of  shares  that  we  will  sell,  or  the  dates  on  which  any  such  sales  will  take  place  The  Sales 
Agreement  will  terminate  upon  the  earlier  of  the  issuance  and  sale  of  all  common  stock  subject  to  the 
Sales  Agreement  or  termination  of  the  Sales  Agreement  by  us  or  MLV.  We  have  provided  MLV  with 
customary indemnification rights. The foregoing description of the Sales Agreement is not complete and 
is qualified in its entirety by reference to the full text of the Sales Agreement, a copy of which is filed as 
Exhibit 10.18 to this Annual Report.     

Contractual Obligations   

We  have  contracted  with  various  vendors  for  research  and  development  services.  The  terms  of 
these  agreements  usually  require  an  initial  fee  and  monthly  or  periodic  payments  over  the  term  of  the 
agreement, ranging from two months to 36 months. The costs to be incurred are estimated and are subject 
to  revision.  As  of  December  31,  2014,  the  total  estimated  cost  to  complete  these  agreements  was 
approximately $8,440,000.    All of these agreements may be terminated by either party upon appropriate 
notice as stipulated in the respective agreements. 

On  June  22,  2009,  we  entered  into  a  License  Agreement  with  Korea  Research  Institute  of 
Chemical  Technology  (“KRICT”)  to  acquire  the  rights  to  all  intellectual  properties  related  to 
Quinoxaline-Piperazine derivatives that were synthesized under a Joint Research Agreement.    The initial 
license fee was $100,000, all of which was paid as of December 31, 2009.    The agreement with KRICT 
calls  for  a  one-time  milestone  payment  of  $1,000,000  within  30  days  after  the  first  achievement  of 
marketing  approval  of  the  first  commercial  product  arising  out  of  or  in  connection  with  the  use  of 
KRICT’s intellectual properties.    As of December 31, 2014, the milestone has not occurred. 

On  June  29,  2009,  we  signed  a  five-year  commercial  lease  agreement  for  5,466  square  feet  of 
office  space  in  Rockville,  Maryland.    Under  the  lease  agreement,  we  pay  our  allocable  portion  of  real 
estate  taxes  and  common  area  operating  charges.  Rent  paid  under  our  lease  during  the  years  ended 
December  31,  2014  and  2013,  including  the  amendments’  terms  described  below,  was  $155,057  and 
$117,977, respectively.    On June 7, 2013, we entered into the first amendment to the lease agreement. 
According  to  the  terms  of  this  amendment,  we  extended  the  lease  term  until  June  30,  2019.    The 
amendment term began on July 1, 2013 with an initial base rent of $100,210 and requires annual base rent 
increases  over  the  remaining  term  of  the  lease.      On  July  26,  2014  we  entered  into  the  second 
amendment to the lease agreement pursuant to which we leased an additional 1,637 square feet of office 
space with an initial term beginning on September 1, 2014 and ending on August 31, 2015.   

50 

 
On  August  26,  2014  and  June  24,  2013,  we  signed  one-year  renewals  to  use  laboratory  space 
commencing  on  July  1,  2014  and  2013,  respectively.    The  laboratory  lease  originally  commenced  on 
July  1,  2009  and  has  thereafter  been  renewed  annually  for  successive  one-year  terms      The  lease 
requires  monthly  rental  payments  of  $4,554.    Rent  paid  under  the  Company’s  lease  during  the  years 
ended December 31, 2014 and 2013 was $54,648.     

We have established a 401(k) plan for our employees.    We have elected to match 100% of the 
first  3%  of  an  employee’s  compensation  plus  50%  of  an  additional  2%  of  the  employee’s  deferral. 
Expense  related  to  this  matching  contribution  aggregated  to  $91,241  and  $78,487  for  the  years  ended 
December 31, 2014 and 2013, respectively. 

In  July  2013,  we  entered  into  an  exclusive  license  agreement  with  the  University  of  Maryland, 
Baltimore for a novel drug delivery platform, Nano-Polymer Drug Conjugate Systems.    RX-21101 is the 
Company’s first drug candidate utilizing this platform.    The agreement requires us make payments to the 
University  of  Maryland  if  RX-21101  or  any  products  from  the  licensed  delivery  platform  achieve 
development milestones.    As of December 31, 2014, no development milestones have occurred. 

In  October  2013  we  signed  an  exclusive  license  agreement  with  the  Ohio  State  Innovation 
Foundation,  for  a  novel  oligonucleotide  drug  delivery  platform,  Lipid-Coated  Albumin  Nanoparticle 
(“LCAN”).    The  agreement  requires  us  to  make  payments  to  the  Ohio  State  Innovation  Foundation  or 
any products from the licensed delivery platform achieve development milestones.    As of December 31, 
2014, no development milestones have occurred. 

Current and Future Financing Needs 

We  have  incurred  negative  cash  flow  from  operations  since  we  started  our  business.  We  have 
spent, and expect to continue to spend, substantial amounts in connection with implementing our business 
strategy,  including  our  planned  product  development  efforts,  our  clinical  trials  and  our  research  and 
development  efforts.  We  will  need  to  raise  additional  capital  through  public  or  private  equity  or  debt 
offerings or through arrangements with strategic partners or other sources in order to continue to develop 
our drug candidates.    There can be no assurance that additional capital will be available when needed or 
on terms satisfactory to us, if at all.    If we are not able to raise sufficient additional capital, we will have 
to reduce our research and development activities. The Company believes that its cash, cash equivalents, 
and marketable securities will be sufficient to cover its cash flow requirements for its current activities for 
at least the next 12 months.

The actual amount of funds we will need to operate is subject to many factors, some of which are 

beyond our control.    These factors include the following: 

(cid:31)

(cid:31)

(cid:31)

(cid:31)

(cid:31)

the progress of our product development activities; 

the number and scope of our product development programs; 

the progress of our pre-clinical and clinical trial activities; 

the  progress  of  the  development  efforts  of  parties  with  whom  we  have  entered  into 
collaboration agreements; 

our ability to maintain current collaboration programs and to establish new collaboration 
arrangements;

Off-Balance Sheet Arrangements 

We do not have any off-balance sheet arrangements.

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

For the year ended December 31, 2014, we are exposed to the following market risks: 

Interest Rate Risk 

We invest our cash in a variety of financial instruments.    At December 31, 2014, our cash was 
invested primarily in short term bank deposits and municipal obligations, all of which were denominated 
in  U.S.  dollars.    Due  to  the  conservative  nature  of  these  investments,  which  primarily  bear  interest  at 
fixed rates, we do not believe we have material exposure to interest rate risk.     

Foreign Currency Risk 

We are exposed to risks associated with foreign currency transactions on contracts with vendors 
associated outside of the United States.    Accordingly changes in the value of the U.S. dollar, relative to 
other currencies, may have an impact on our financial statements and earnings.    The number and dollar 
amount of contracts denominated in foreign currency is immaterial; therefore, we believe we do not have 
material exposure to foreign currency risk.

Item 9. Changes In and Disagreements With Accountants on Accounting and Financial Disclosure. 

None.

Item 9A.    Controls and Procedures.   

Evaluation  of  Disclosure  Controls  and  Procedures.  Under  the  supervision  and  with  the 
participation of our management, including our Chief Executive Officer and Chief Financial Officer, we 
evaluated  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 Securities Exchange Act of 1934 (the “Exchange Act”)) 
as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer 
and  Chief  Financial  Officer  concluded  that  our  disclosure  controls  and  procedures  as  of  the  end  of  the 
period covered by this report were effective such that the information required to be disclosed by us in 
reports filed under the Exchange Act is (i) recorded, processed, summarized and reported within the time 
periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, 
including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions 
regarding disclosure. A controls system cannot provide absolute assurance, however, that the objectives of 
the controls system are met, and no evaluation of controls can provide absolute assurance that all control 
issues and instances of fraud, if any, within a company have been detected. 

Changes  in  Internal  Control  Over  Financial  Reporting.    During  the  most  recent  quarter  ended 
December 31, 2014, there has been no change in our internal control over financial reporting (as defined in 
Rule 13a-15(f) and 15d-15(f) under the Exchange Act) ) that has materially affected, or is reasonably likely 
to materially affect, our internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING 

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over 
financial  reporting  (as  defined  in  Rule 13a-15(f)  under  the  Exchange  Act).    Our  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 
generally accepted accounting principles and includes those policies and procedures that:     

(cid:31)

(cid:31)

(cid:31)

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

Provide reasonable assurance that transactions are recorded as necessary to permit 
preparation  of  financial  statements  in  accordance  with  generally  accepted 
accounting principles, and that our receipts and expenditures are being made only in 
accordance with authorization of our management and the board of directors; and 

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements.    Also, projections of any evaluations of effectiveness to future periods are subject to risk 
that controls may become inadequate because of changes in conditions or because of declines in the degree 
of compliance with the policies or procedures.     

Our management, with the participation of the Chief Executive Officer and Chief Financial Officer, 
assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December 31,  2014.    In 
making  this  assessment,  our  management  used  the  criteria  set  forth  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission in the Internal Control-Integrated Framework (2013). 

Based on this evaluation, our management, with the participation of the Chief Executive Officer and 
Chief  Financial  Officer,  concluded  that,  as  of  December  31,  2014  our  internal  control  over  financial 
reporting was effective.     

Management’s  assessment  of  the  effectiveness  of  the  Company’s  internal  control  over  financial 
reporting  has  been  audited  by  Baker  Tilly  Virchow  Krause,  LLP,  an  independent  registered  public 
accounting firm.    Baker Tilly Virchow Krause, LLP has issued an attestation report on the effectiveness of 
the Company’s internal control over financial reporting, which appears herein.

Report of Independent Registered Public Accounting Firm 

Board of Directors and Stockholders 
Rexahn Pharmaceuticals, Inc.   

We have audited Rexahn Pharmaceuticals Inc.’s internal control over financial reporting as of December 
31,  2014,  based  on  criteria  established  in  Internal  Control—Integrated  Framework  (2013  framework) 
issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  Rexahn 
Pharmaceuticals Inc.’s management is responsible for maintaining effective internal control over financial 
reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in 
the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility 
is to express an opinion on the entity’s internal control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight 
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether effective internal control over financial reporting was maintained in all material 
respects. Our audit of internal control over financial reporting included obtaining an understanding of 
internal control over financial reporting, assessing the risk that a material weakness exists, and testing and 
evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit 
also included performing such other procedures as we considered necessary in the circumstances. We 
believe that our audit provides a reasonable basis for our opinion. 

An entity’s 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 accounting principles generally accepted in the United States of America. An 
entity’s internal control over financial reporting includes those policies and procedures that (1) pertain to 
the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the entity; (2) provide reasonable assurance that transactions are recorded as 
necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the entity are being made only in accordance with 
authorizations of management and directors of the entity; and (3) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the entity’s assets that 
could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk 
that controls may become inadequate because of changes in conditions, or that the degree of compliance 
with the policies or procedures may deteriorate. 

(cid:31) (cid:31)

In our opinion, Rexahn Pharmaceuticals Inc. maintained, in all material respects, effective internal control 
over  financial  reporting  as  of  December 31,  2014,  based  on  criteria  established  in  Internal 
Control—Integrated Framework (2013 framework) issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO). 

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight 
Board  (United  States),  the  balance  sheets  and  the  related  statements  of  operations,  comprehensive  loss, 
stockholders’ equity, and cash flows of Rexahn Pharmaceuticals Inc., and our report dated March 16, 2015 
expressed an unqualified opinion.

Report of Independent Registered Public Accounting Firm 

Board of Directors and Stockholders 
Rexahn Pharmaceuticals, Inc. 

We have audited the accompanying balance sheet of Rexahn Pharmaceuticals, Inc. as of December 31, 2014 
and 2013, and the related statements of operations, comprehensive loss, stockholders’ equity, and cash flows 
the years then ended. These financial statements are the responsibility of the entity’s management. Our 
responsibility is to express an opinion on these financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight 
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of material misstatement. An audit includes 
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An 
audit also includes assessing the accounting principles used and significant estimates made by management, 
as well as evaluating the overall financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion. 

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial 
position of Rexahn Pharmaceuticals, Inc. as of December 31, 2014 and 2013, 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.   

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), Rexahn Pharmaceuticals, Inc.’s internal control over financial reporting as of December 31, 
2014, based on criteria established in Internal Control—Integrated Framework (2013 framework) issued by 
the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated 
March 16, 2015 expressed an unqualified opinion.

Notes to Financial Statements 

1.  Operations and Organization 

Operations

Rexahn  Pharmaceuticals,  Inc.  (the  “Company,”  or  “Rexahn  Pharmaceuticals”),  a  Delaware 
corporation,  is  a  biopharmaceutical  company  whose  principal  operations  are  the  discovery, 
development  and  commercialization  of  innovative  treatments  for  cancer  and  other  medical  needs.   
The  Company  had  an  accumulated  deficit  of  $91,332,308  at  December  31,  2014  and  anticipates 
incurring  losses  through  fiscal  year  2015  and  beyond.    The  Company  has  not  yet  generated 
commercial  revenues  and  has  funded  its  operating  losses  to  date  through  the  sale  of  shares  of  its 
common stock and warrants to purchase shares of its  common stock, convertible debt, financings, 
interest  income  from  cash,  cash  equivalents  and  marketable  securities,  and  proceeds  from 
reimbursed  research  and  development  costs.        The  Company  believes  that  its  cash,  cash 
equivalents, and marketable securities, will be sufficient to cover its cash flow requirements for its 
current activities for at least the next 12 months.    Management has the capability of managing the 
Company’s  operations  within  existing  cash  available  by  focusing  on  select  research  and 
development  activities,  selecting  projects  in  conjunction  with  potential  financings  and  milestones, 
and efficiently managing its general and administrative affairs. 

2. Summary of Significant Accounting Policies 

a) Cash and Cash Equivalents 

Cash  and  cash  equivalents  include  cash  on  hand  and  short-term  investments  purchased  with 
remaining maturities of three months or less at acquisition. 

b) Marketable Securities 

Marketable securities are considered “available-for-sale” in accordance with Financial Statement 
Accounting Board (“FASB”) Accounting Standard Codification (“ASC”) 320, “Debt and Equity 
Securities”, and thus are reported at fair value in the Company’s accompanying balance sheet, with 
unrealized  gains  and  losses  excluded  from  earnings  and  reported  as  a  separate  component  of 
stockholders’ equity.    Amounts reclassified out of accumulated other comprehensive income into 
realized gains and losses are accounted for on the basis of specific identification and are included in 
other income or expense in the statement of operations.    The Company classifies such investments 
as current on the balance sheet as the investments are readily marketable and available for use in 
Rexahn Pharmaceuticals’ current operations.     

c) Equipment 

Equipment is stated at cost less accumulated depreciation. Depreciation, based on the lesser of the 
term of the lease or the estimated useful life of the assets, is provided as follows: 

Life Depreciation Method 

Furniture and fixtures 
Office equipment 
Lab equipment 
Computer equipment 
Leasehold improvements 

7 years
5 years
5-7 years
3-5 years
3-5 years

F-8

 
 
 
REXAHN PHARMACEUTICALS, INC.
Notes to Financial Statements 

d) Research and Development   

Research and development costs are expensed as incurred.    Research and development expenses 
consist primarily of third party service costs under research and development agreements, salaries 
and related personnel costs, as well as stock compensation related to these costs, costs to acquire 
pharmaceutical products and product rights for development and amounts paid to contract research 
organizations,  hospitals  and  laboratories  for  the  provision  of  services  and  materials  for  drug 
development and clinical trials. 

Costs incurred in obtaining the licensing rights to technology in the research and development stage 
that have no alternative future uses and are for unapproved product compounds are expensed as 
incurred.

e) Use of Estimates 

The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally 
accepted in the United States requires management to make estimates and assumptions that affect 
the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities 
at the date of the financial statements and the reported amounts of revenues and expenses during the 
reporting period.    These estimates are based on management’s best knowledge of current events 
and actions the Company may undertake in the future.    Actual results may ultimately differ from 
these estimates.    These estimates are reviewed periodically and as adjustments become necessary, 
they are reported in earnings in the period in which they become available. 

f) Fair Value of Financial Instruments 

The  carrying  amounts  reported  in  the  accompanying  financial  statements  for  cash  and  cash 
equivalents, prepaid expenses and other current assets, the security deposit and accounts payable 
and accrued expenses approximate fair value because of the short-term maturity of these financial 
instruments.    The fair value for marketable securities, warrant liabilities, and certain other assets 
and liabilities is discussed in Notes 3, 12, and 15, respectively. 

g) Income Taxes 

The Company accounts for income taxes in accordance with ASC 740, “Income Taxes”.    Deferred 
tax assets and liabilities are recorded for differences between the financial statement and tax basis 
of the assets and liabilities that will result in taxable or deductible amounts in the future based on 
enacted tax laws and rates.    ASC 740 requires that a valuation allowance be established when it is 
more likely than not that all portions of a deferred tax asset will not be realized.    A review of all 
positive  and  negative  evidence  needs  to  be  considered,  including  a  company’s  current  and  past 
performance,  the  market  environment  in  which  the  company  operates,  length  of  carryback  and 
carryforward periods and existing contracts that will result in future profits.    Income tax expense is 
recorded for the amount of income tax payable or refundable for the period, increased or decreased 
by the change in deferred tax assets and liabilities during the period. 

As a result of the Company’s significant cumulative losses, the Company determined that it was 
appropriate to establish a valuation allowance for the full amount of deferred tax assets. 

The calculation of the Company’s tax liabilities involves the inherent uncertainty associated with 
the application of complex tax laws.    The Company is subject to examination by various taxing 

F-9

 
REXAHN PHARMACEUTICALS, INC.
Notes to Financial Statements 

authorities.    The Company believes that, as a result of its loss carryforward sustained to date, any 
examination would result in a reduction of its net operating losses rather than a tax liability.    As 
such, the Company has not provided for any additional taxes that would be estimated under ASC 
740. 

h) Stock-Based Compensation 

In accordance with ASC 718, “Stock Compensation,” compensation costs related to share-based 
payment  transactions,  including  employee  stock  options,  are  to  be  recognized  in  the  financial 
statements.  In  addition,  the  Company  adheres  to  the  guidance  set  forth  within  Securities  and 
Exchange Commission (“SEC”) Staff Accounting Bulletin (“SAB”) No. 107, which provides the 
Staff’s views regarding the interaction between ASC 718 and certain SEC rules and regulations, 
and  provides  interpretations  with  respect  to  the  valuation  of  share-based  payments  for  public 
companies.   

i) Concentration of Credit Risk 

ASC 825, “Financial Instruments,” requires disclosure of any significant off balance sheet risk and 
credit risk concentration.    The Company does not have significant off-balance sheet risk or credit 
concentration.    The  Company  maintains  cash  and  cash  equivalents  with  major  financial 
institutions.    From time to time the Company has funds on deposit with commercial banks that 
exceed  federally  insured  limits.    The  balances  are  insured  by  the  Federal  Deposit  Insurance 
Corporation up to $250,000. At December 31, 2014, the Company’s uninsured cash balance was 
$7,671,892. Management does not consider this to be a significant credit risk as the banks are large, 
established financial institutions. 

j) Reclassification 

Certain amounts in the prior year’s financial statements have been reclassified to conform to the 
current year presentation with no material effect on the financial statements.   

k) Recent Accounting Pronouncements Affecting the Company 

Development Stage Entities: Elimination of Certain Financial Reporting Requirements, Including 
an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation 

In  June  2014,  the  Financial  Accounting  Standards  Board  (the  “FASB”)  issued  Accounting 
Standards  Update  (“ASU”)  2014-10  “Development  Stage  Entities:  Elimination  of  Certain 
Financial  Reporting  Requirements,  Including  an  Amendment  to  Variable  Interest  Entities 
Guidance  in  Topic  810,  Consolidation.”    ASU  2014-10  eliminates  several  of  the  reporting 
requirements for development stage entities, including the requirement to present inception to date

equity, and to label the financial statements as those of a development stage entity.    ASU 2014-10 
also clarifies that the guidance in Accounting Standards Codification (“ASC”) Topic 275, “Risks 
and  Uncertainties”,  is  applicable  to  entities  that  have  not  commenced  principal  operations,  and 
eliminates an exception to the sufficiency-of-equity risk criterion for development stage entities, 
and will require all reporting entities that have an interest in development stage enterprises to apply 
consistent consolidation guidance for variable interest entities.    ASU 2014-10 is effective for all 
annual reporting periods beginning after December 15, 2014, with early adoption permitted.    The 
Company  adopted  ASU  2014-10  during  the  year  ended  December  31,  2014,  and  removed  the 
incremental reporting requirements for development stage entities from the financial statements for 
this period.

Revenue from Contracts with Customers

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers”, a 
comprehensive new revenue recognition standard that will supersede nearly all existing revenue 
recognition guidance under US Generally Accepted Accounting Principles.    The standard’s core 
principle is that a company should recognize revenue when it transfers goods or services to 
customers in an amount that reflects the consideration to which the company expects to be 
entitled in exchange for those goods and services, and provides a revenue recognition framework 
in accordance with this principle.    ASU 2014-09 is effective for annual reporting periods 
beginning after December 15, 2016 and interim periods therein.    The Company is currently 
evaluating the impact that the adoption of this guidance will have on its financial statements and 
future operating results. 

Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern 

In August 2014, the FASB issued ASU 2014-15: Disclosure of Uncertainties about an Entity’s 
Ability to Continue as a Going Concern, which requires management to perform interim and 
annual assessments as to the entity’s ability to continue as a going concern and provides related 
disclosure guidance.    ASU 2014-15 will be effective for reporting periods beginning after 
December 15, 2016, with early adoption permitted. The Company is currently evaluating the 
impact the adoption of this guidance will have on its financial statements.

The  Company  typically  invests  in  highly-rated  securities,  with  the  primary  objective  of  minimizing 
the  potential  risk  of  principal  loss.    As  of  December  31,  2014,  the  Company  had  certificates  of 
deposit with a fair value of $18,598,211 and unrealized losses of $26,789, commercial paper with a 
fair  value  of  $998,180  and  unrealized  losses  of  $153,  and  corporate  bonds  with  a  fair  value  of 
$2,035,870 and unrealized losses of $6,827, all of which have been unrealized losses for less than 12 
months.    The Company does not have the intent to sell its marketable securities in an unrealized loss 
position.    Based  upon  the  Company’s  securities’  fair  value  relative  to  the  cost,  high  ratings,  and 
volatility  of  fair  value,  the  Company  considers  the  declines  in  market  value  of  its  marketable

7.    Deferred Research and Development Arrangements

Rexgene Biotech Co., Ltd. 

In 2003, the Company entered into a collaborative research agreement with Rexgene Biotech Co., 
Ltd.  (“Rexgene”),  a  shareholder.    Rexgene  is  engaged  in  the  development  of  pharmaceutical 
products in Asia and has agreed to assist the Company with the research, development and clinical 
trials  necessary  for  registration  of  the  Company’s  drug  candidate  Archexin  in  Asia.    This 
agreement provides Rexgene with exclusive rights to license, sublicense, make, have made, use, sell 
and  import  Archexin  in  Asia.    In  accordance  with  the  agreement,  Rexgene  paid  the  Company  a 
one-time fee of $1,500,000 in 2003.    The agreement terminates at the later of 20 years or the term 
of  the  patent.    The  amortization  reduces  research  and  development  expenses  for  the  periods 
presented.     

The  Company  is  using  20  years  as  its  basis  for  recognition  and  accordingly  research  and 
development expenses were reduced by $75,000 for the years ended December 31, 2014 and 2013, 
respectively.    The  remaining  $600,000  and  $675,000  to  be  amortized  at  December  31,  2014  and 
December 31, 2013, respectively, are reflected as deferred research and development arrangements 
on the balance sheet.    The payment from Rexgene is being used in the cooperative funding of the 
costs  of  development  of  Archexin.  Royalties  of  3%  of  net  sales  of  licensed  products  will  become 
payable by Rexgene to the Company on a quarterly basis once commercial sales of Archexin begin 
in Asia.    The product is still under development and commercial sales in Asia are not expected to 
begin until at least 2016.    Under the terms of the agreement, Rexgene does not receive royalties on 
the Company’s net sales outside of Asia.   

Teva Pharmaceutical Industries, Ltd. 

On  September  21,  2009,  the  Company  closed  on  a  securities  purchase  agreement  (the  “Purchase 
Agreement”) with Teva Pharmaceutical Industries Limited (“Teva”), and contemporaneous with the 
execution  and  delivery  of  the  Purchase  Agreement,  the  parties  executed  a  research  and  exclusive 
license option agreement (the “RELO Agreement”) pursuant to which the Company agreed to use 
proceeds from the issuance and sale of shares to Teva to fund a research and development program 
for  the  pre-clinical  development  of  RX-3117.    On  November  27,  2012,  the  Company  and  Teva 
entered  into  a  second  amendment  to  the  RELO  Agreement,  pursuant  to  which  Teva  provided  the 
Company with an additional $926,000 of research funding for the development of RX-3117, which 
was recorded as restricted cash on the Company’s balance sheet.    The contribution from the second 
amendment was recorded in deferred research and development arrangements on the balance sheet.   
Costs incurred for the development of RX-3117 were paid from restricted cash, reduced the deferred 
research  and  development  arrangement  and  therefore  were  not  an  expense  in  the  Company’s 
statement of operations.    On August 28, 2013, the Company announced that Teva had decided not 
to exercise its option to license RX-3117, and as a result the RELO Agreement was terminated, and 
any  proceeds  remaining  from  the  restricted  cash  at  that  time  would  be  used  to  pay  for  unbilled 
expenses.    As  of  December  31,  2013,  the  Company  had  proceeds  remaining  of  $158,630,  which 
was included in restricted cash and deferred research and development arrangements on the balance 
sheet.    During  the  year  ended  December  31,  2014,  $158,630  was  reduced  from  the  deferred 
research and development arrangement to pay for costs incurred for the development of RX-3117, 
and  therefore,  as  of  December  31,  2014,  no  proceeds  remained  in  restricted  cash  or  a  deferred 
research and development liability related to Teva.

8. Other Liabilities 

Deferred Lease Incentive 

On June 29, 2009, the Company entered into a five-year office lease agreement as disclosed in Note 
14.    The lessor agreed to grant a leasehold improvement allowance of $100,000 to the Company to 
be  used  for  the  construction  cost  of  improvements  to  the  leased  property,  which  included 
architectural and engineering fees, government agency plan check, permit and other fees, sales and 
use  taxes,  testing  and  inspection  costs  and  telephone  and  data  cabling  and  wiring  in  the  premises.   
The Company accounted for the benefit of the leasehold improvement allowance as a reduction of 
rental expense over the five-year term of the office lease. 

On  June  7,  2013,  the  Company  entered  into  the  first  amendment  to  the  lease  agreement,  also 
disclosed  in  Note  14.  According  to  the  terms  of  the  amendment,  the  Company  extended  the  lease 
term  until  June  30,  2019,  and  the  amendment  term  began  on  July  1,  2013.    The  lessor  agreed  to 
grant  an  additional  leasehold  improvement  allowance  of  $54,660  to  the  Company  to  be  used  for 
further  construction  to  the  leased  property,  furniture  and  equipment.    The  Company  accounts  for 
this benefit, including the unamortized portion from the original lease agreement, as a reduction of 
rental expense over the six-year amended term of the lease. 

The following table sets forth the cumulative deferred lease incentive:

The lease agreement, as amended and disclosed above, requires an initial annual base rent with 
annual increases over the next six years.    The Company recognizes rental expense on a straight-line 
basis over the term of the lease, which resulted in a deferred rent liability of $68,960 and $61,126 as 
of December 31, 2014 and 2013, respectively. 

9.  Net Loss per Common Share

Basic loss per common share is computed by dividing net loss by the weighted average number of 
shares of common stock outstanding for the period.    Diluted loss per common share is computed by 
dividing net loss by the weighted average number of shares of common stock outstanding, plus the 
number of common share equivalents that would be dilutive.    As of December 31, 2014 and 2013, 
there  were  stock  options  and  warrants  to  acquire,  in  the  aggregate,  24,606,677  and  34,325,663 
shares of the Company’s common stock, respectively, that are potentially dilutive. However, diluted 
loss per share for all periods presented is the same as basic loss per share because the inclusion of 
common share equivalents would be anti-dilutive.

11. Stock-Based Compensation

As of December 31, 2014, the Company had 11,400,806 options outstanding.

consultants of the Company.    A total of 17,000,000 shares of common stock have been reserved for 
issuance  pursuant  to  the  2013  Plan.    As  of  December  31,  2014,  there  were  2,978,499  options 
outstanding under the 2013 Plan, and 14,021,501 shares were available for issuance from the 2013 
Plan.

On  August  5,  2003,  the  Company  established  a  stock  option  plan  (the  “2003  Plan”).    Under  the 
2003  Plan,  the  Company  granted  stock  options  to  key  employees,  directors  and  consultants  of  the 
Company.    With the adoption of the 2013 Plan, no new stock options may be issued under the 2003 
Plan,  but  previously  issued  options  under  the  2003  Plan  remain  outstanding  until  their  expiration.   
As of December 31, 2014, there were 8,422,307 outstanding options under the 2003 Plan. 

For the majority of the grants to employees, the vesting period is 30% on the first anniversary of the 
grant date, an additional 30% on the second anniversary of the grant date and the remaining 40% on 
the third anniversary.    Options expire between five and ten years from the date of grant. For grants 
to  non-employee  consultants  of  the  Company,  the  vesting  period  is  between  one  and  three  years, 
subject to the fulfillment of certain conditions in the individual stock agreements, or 100% upon the 
occurrence of certain events specified in the individual stock agreements. 

Accounting for Employee Awards 

The  Company’s  results  of  operations  for  the  years  ended  December  31,  2014  and  2013  include 
stock-based  employee  compensation  expense  totaling  $587,414  and  $553,163  respectively.  Such 
amounts  have  been  included  in  the  statement  of  operations  in  general  and  administrative  and 
research and development expenses.    No income tax benefit has been recognized in the statement of 
operations  for  stock-based  compensation  arrangements  as  the  Company  has  provided  for  a  100% 
valuation allowance on its deferred tax assets. 

Employee  stock  option  compensation  expense  is  the  estimated  fair  value  of  options  granted 
amortized on a straight-line basis over the requisite vesting service period for the entire portion of 
the award.   

Accounting for Non-Employee Awards

Stock-based compensation expenses related to non-employee options were $21,381 and $12,265 for 
the years ended December 31, 2014 and 2013, respectively.    Such amounts have been included in 
the statement of operations in general and administrative and research and development expenses.

Summary of Stock Option Transactions 

There were 2,528,499 stock options granted at exercise prices ranging from $0.68 to $1.35 with an 
aggregate  fair  value  of  $1,737,087  during  the  year  ended  December  31,  2014.    There  were 
2,450,000 stock options granted at exercise prices ranging from $0.31 to $0.61 with an aggregate fair 
value of $681,752 during the year ended December 31, 2013. 

The fair value of options at the date of grant was estimated using the Black-Scholes option pricing 
model.    The  Company  took  into  consideration  guidance  under  ASC  718,  “Compensation-Stock 
Compensation” and Staff Accounting Bulletin No. 107 (“SAB 107”) when reviewing and updating 
assumptions.    The  expected  volatility  is  based  upon  historical  volatility  of  the  Company’s  stock.   
The expected term is based upon the simplified method as allowed under SAB 107.

At December 31, 2014 and 2013, the average remaining contractual life of the outstanding warrants 
was 3.2 years.   

The  warrants  issued  to  investors  in  the  June  2009,  October  2009,  June  2010,  March  2011  and 
December  2012  offerings  contain  a  provision  for  net  cash  settlement  in  the  event  that  there  is  a 
fundamental  transaction  (contractually  defined  as  a  merger,  sale  of  substantially  all  assets,  tender 
offer  or  share  exchange).    If  a  fundamental  transaction  occurs  in  which  the  consideration  issued 

F-23

 
     
 
REXAHN PHARMACEUTICALS, INC.
Notes to Financial Statements 

consists principally of cash or stock in a non-public company, then the warrant holder has the option 
to receive cash, equal to the fair value of the remaining unexercised portion of the warrant.    Due to 
this contingent redemption provision, the warrants require liability classification in accordance with 
ASC 480 and are recorded at fair value.    The warrants issued to investors in the July 2013, October 
2013  and  January  2014  offerings  contain  a  fundamental  transaction  provision,  but  the  warrant 
holders only have an option as to the type of consideration received if the holders of common stock 
receive  an  option  as  to  their  consideration.    In  addition,  the  warrants  issued  in  the  June  2009, 
October 2009, June 2010, March 2011, December 2012, July 2013, October 2013, and January 2014 
offerings contain a cashless exercise provision that is exercisable only in the event that a registration 
statement is not effective. That provision may not be operative if an effective registration statement 
is not available because an exemption under the U.S. securities laws may not be available to issue 
unregistered  shares.    As  a  result,  net  cash  settlement  may  be  required,  and  the  warrants  require 
liability classification. 

ASC  820  provides  requirements  for  disclosure  of  liabilities  that  are  measured  at  fair  value  on  a 
recurring  basis  in  periods  subsequent  to  the  initial  recognition.    Fair  values  for  warrants  are 
determined using the Binomial Lattice (“Lattice”) valuation technique. The Lattice model provides 
for  dynamic  assumptions  regarding  volatility  and  risk-free  interest  rates  within  the  total  period  to 
maturity.  Accordingly,  within  the  contractual  term,  the  Company  provided  multiple  date  intervals 
over  which  multiple  volatilities  and  risk  free  interest  rates  were  used.  These  intervals  allow  the 
Lattice  model  to  project  outcomes  along  specific  paths  that  consider  volatilities  and  risk  free  rates 
that would be more likely in an early exercise scenario.   

Significant assumptions are determined as follows:   
Trading market values—Published trading market values;   
Exercise price—Stated exercise price;   
Term—Remaining contractual term of the warrant;   
Volatility—Historical trading volatility for periods consistent with the remaining terms;   
Risk-free rate—Yields on zero coupon government securities with remaining terms consistent with 
the remaining terms of the warrants.   

Due  to  the  fundamental  transaction  provision,  which  could  provide  for  early  redemption  of  the 
warrants,  the  model  also  considered  the  probability  the  Company  would  enter  into  a  fundamental 
transaction  during  the  remaining  term  of  the  warrant.  Because  the  Company  is  not  yet  achieving 
positive cash flow, management believes the probability of a fundamental transaction occurring over 
the  term  of  the  warrant  is  unlikely  and  therefore  estimates  the  probability  of  entering  into  a 
fundamental transaction to be 5%.    For valuation purposes, the Company also assumed that if such 
a transaction did occur, it was more likely to occur towards the end of the term of the warrants. 

The  significant  unobservable  inputs  used  in  the  fair  value  measurement  of  the  warrants  include 
management’s  estimate  of  the  probability  that  a  fundamental  transaction  may  occur  in  the  future.   
Significant  increases  (decreases)  in  the  probability  of  occurrence  would  result  in  a  significantly 
higher (lower) fair value measurement.

13. Income Taxes

No provision for federal and state income taxes was required for the years ended December 31, 2014 
and  2013  due  to  the  Company’s  operating  losses  and  increased  deferred  tax  asset  valuation 
allowance.    At  December  31,  2014  and  2013,  the  Company  had  unused  net  operating  loss 
carry-forwards of approximately $81,619,000 and $69,036,000, respectively, which expire at various 
dates  through  2034.    Some  of  this  amount  may  be  subject  to  annual  limitations  under  certain 
provisions of the Internal Revenue Code related to “changes in ownership.”     

As  of  December  31,  2014  and  2013,  the  deferred  tax  assets  related  to  the  aforementioned 
carry-forwards have been fully offset by valuation allowances, because significant utilization of such 
amounts is not presently expected in the foreseeable future.     

Deferred tax assets and valuation allowances consist of:

15.    Fair Value Measurements 

ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a 
liability in an orderly transaction between market participants at the measurement date, not adjusted 
for transaction costs.    ASC 820 also establishes a fair value hierarchy that prioritizes the inputs to 
valuation techniques used to measure fair value into three broad levels giving the highest priority to 
quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to 
unobservable inputs (Level 3).     

The three levels are described below:   

Level 1 Inputs  — Unadjusted quoted prices in active markets for identical assets or 
liabilities that are accessible by the Company; 

Level 2 Inputs  — Quoted prices in markets that are not active or financial instruments for 
which all significant inputs are observable, either directly or indirectly; 

Level 3 Inputs  — Unobservable inputs for the asset or liability including significant 

assumptions of the Company and other market participants. 

The following tables present assets and liabilities that are measured at fair value on a recurring 
basis  and  are  categorized  using  the  fair  value  hierarchy.    There  have  been  no  changes  in  the 
methodologies used at December 31, 2014 and 2013.

As  of  December  31, 2013,  the  Company’s  restricted  cash  equivalents  also  included  money market 
funds valued at net asset value of shares held by the Company and classified within level 1 of the fair 
value  hierarchy,  and  a  certificate  of  deposit,  valued based  upon  the  underlying  terms  of  a  letter  of

REXAHN PHARMACEUTICALS, INC.
Notes to Financial Statements 

credit, as disclosed in Note 14, and classified within level 2 of the fair value hierarchy. 

The fair value of the Company’s Level 2 marketable securities is determined by using quoted prices 
from independent pricing services that use market data for comparable securities in active or inactive 
markets.    A  variety  of  data  inputs,  including  benchmark  yields,  interest  rates,  known  historical 
trades and broker dealer quotes are using with pricing models to determine the quoted prices. 

The fair value methodology for the warrant liabilities is disclosed in Note 12. 

The carrying amounts reported in the financial  statements for cash  and  cash  equivalents (Level  1), 
prepaid expenses, and other current assets and accounts payable and accrued expenses approximate 
fair value because of the short term maturity of these financial instruments. 

The following table sets forth a reconciliation of changes in the years ended December 31, 2014 and 
2013 in the fair value of the liabilities classified as Level 3 in the fair value hierarchy: 

Balance at January 1, 2014

Additions consist of the fair value of warrant liabilities upon issuance.    Transfers out of Level 3 for 
warrant liabilities consist of warrant exercises, where the liability is converted to additional paid-in 
capital upon exercise.    The Company’s policy is to recognize transfers in and transfers out as of the 
actual date of the event or change in circumstance that caused the transfer.
