To Our Stockholders and Friends: 

These are truly exciting times at CytRx Corporation (CytRx), as progress with our clinical programs 
has  moved  us  significantly  closer  to  our  goal  of  commercializing  drugs  aimed  at  reducing  human 
suffering.  We  are  rapidly  approaching  our  planned  initiation  of  a  Phase  II  clinical  trial  for 
amyotrophic  lateral  sclerosis  (ALS,  more  commonly  known  as  Lou  Gehrig’s  disease),  a  life-
threatening  and  debilitating  condition  for  which  there  is  currently  no  effective  treatment.  In  addition, 
we are evaluating patients’ immune response in our Phase I HIV program in collaboration with the 
University  of  Massachusetts  Medical  School  (UMMS)  and  Advanced  BioScience  Laboratories 
(ABL) and funded by the National Institute of Allergy and Infectious Diseases (NIAID), which is part of 
the  National  Institutes  of  Health.  In  the  fall  of  this  year,  we  expect  to  announce  interim  immune 
response  results  from  our  HIV  program.  Further,  we  are  exploring  potential  strategic  partnerships 
through which it is possible that up to two additional Phase II clinical development programs may be 
initiated before the end of next year. 

We have done much during the past year to transform CytRx from a drug discovery entity to a drug 
development  company.  We  embarked  on  an  ambitious  plan  that  has  enabled  us  to  reach  the 
important  clinical  juncture  of  preparing  to  enter  a  Phase  II  clinical  trial.  Among  our  more  notable 
achievements  in  2004  was  seizing  the  opportunity  last  October  to  acquire  breakthrough  small 
molecule  technology  that  included  three  oral,  clinical  stage  drug  candidates  and  a  library  of  500 
small  molecule  drug  candidates.  This  represents  an  exceptional  strategic  fit  with  our  innovative 
ribonucleic  acid  interference,  or  RNAi,  technology,  as  both  employ  mechanisms  of  action  that  we 
believe  repair  or  prevent  the  production  of  toxic,  misfolded  or  mutant  proteins.  Our  small  molecule 
technology  is  believed  to  function  by  stimulating  a  normal  cellular  protein  repair  pathway  through 
the activation of “molecular chaperones.” Since damaged proteins called  aggregates are thought to 
play  a  role  in  many  diseases,  we  believe  that  activation  of  molecular  chaperones  could  have 
therapeutic  efficacy  for  a  broad  range  of  diseases.  Our  small  molecules  are  more  clinically 
advanced than our RNAi programs, providing us the prospect of hastening our move into Phase II 
trials. 

From  a  scientific  standpoint,  CytRx  is  now  in  the  very  enviable  position  of  having  innovative  small 
molecule,  RNAi  and  antiviral  vaccine  drug  candidates  that  have  potential  in  numerous  indications, 
including  neurodegenerative  diseases  such  as  ALS,  diabetes  and  related  conditions, 
cardiovascular  disease  and  HIV.  Our  robust  drug  development  pipeline  and  drug  discovery 
capabilities enables us to move forward with our programs, and to pursue corporate partnering and 
licensing agreements for the development of a select group of our disease indications. 

Planned Entry into Phase II Trial for Lou Gehrig’s Disease 

We  are  excited  about  the  possibility  of  developing  an  effective  therapeutic  treatment  for  the 
neurodegenerative  disease  ALS,  the  focus  of  our  lead  clinical  program,  and  we  expect  to 
commence  our  Phase  II  program  this  quarter.  According  to  the  ALS  Survival  Guide,  50  percent  of 
ALS patients die within 18 months of diagnosis and 80 percent die within five years. In the U.S., an 
estimated 30,000 people are living with ALS and nearly 6,000 new cases are diagnosed each year. 
According  to  the  ALS  Association,  more  than  120,000  people  are  afflicted  with  ALS  worldwide. 
Unfortunately, the only drug currently approved extends a patient’s lifespan by an average of only 60 
days. As would be expected with a paralytic disease, the monetary cost to these patients is high, 
estimated at approximately $200,000 per patient per year. 

In  experimental  animal  models,  our  orally-administered  drug  arimoclomol  has  shown  extensive 
neuroprotective efficacy, including in an animal model of ALS. Further, it was well tolerated in early-
stage  human  trials.  Because  of  the  relative  rarity  of  this  disease  and  the  current  lack  of  effective 
treatment, we applied for and were granted orphan drug status for arimoclomol for this indication. 

 
 
 
This  is  an  important  milestone  for  CytRx,  as  receipt  of  orphan  designation  holds  numerous 
potential  benefits,  including  opportunities  for  grant  funding  towards  clinical  trial  costs,  tax 
advantages,  U.S.  Food  and  Drug  Administration  (FDA)  user-fee  benefits,  seven  years  of  U.S. 
market exclusivity should the FDA grant marketing approval for the drug and an added mechanism 
for more frequent communication with the FDA. 

Again, due to the lack of a therapeutic treatment, a Phase II trial demonstrating significant efficacy 
could be sufficient to enable us to submit a New Drug Application for the marketing of arimoclomol. 
We are exceptionally pleased to report that Dr. Robert Brown, Jr., founder and director of the Cecil B. 
Day  Laboratory  for  Neuromuscular  Research  at  Massachusetts  General  Hospital,  professor  of 
neurology  at  Harvard  Medical  School  and  a  noted  ALS  authority,  has  agreed  to  be  the  principal 
investigator for this trial. Dr. Brown is a member of the CytRx scientific advisory board and we are 
pleased to have a clinician of his caliber involved with this potentially ground breaking program. 

Promising Data in Type 2 Diabetes 

Among the advantages of working with a small molecule that we believe acts as an activator of a 
general cellular repair mechanism is that the same drug may have therapeutic potential in multiple 
indications.  The  potential  versatility  of  this  mechanism  of  action  of  arimoclomol  is  demonstrated  by 
the  compelling  biological  activity  observed  in  experiments  relating  to  such  apparently  unrelated 
animal models as ALS and type 2 diabetes. 

Diabetes  afflicts  about  18.2  million  Americans,  of  which  90%  suffer  from  the  type  2  form  of  this 
disease, according to the Centers for Disease Control and Prevention. In 2002, direct medical and 
indirect  expenditures  attributable  to  diabetes  were  estimated  at  $132  billion  by  the  American 
Diabetes  Association.  Patients  with diabetes tend to accumulate more glucose in their bloodstream 
after eating than those without diabetes. Type 2 diabetes results from abnormally poor metabolism of 
glucose. 

Obese diabetic animals that were fed large amounts of glucose showed a higher level of glucose in 
their  blood  and  maintained  the  corresponding  glucose  levels  for  a  longer  time  period  than  non-
diabetic  animals.  Diabetic  rats  treated  concurrently  with  arimoclomol  and  metformin,  a  commonly 
prescribed  type  2  diabetes  drug,  showed  restored  normal  serum  glucose  levels  in  these  obese 
diabetic animal models. 

It  is  believed  that  type  2  diabetes  may  be  caused  in  part  by  the  accumulation  of  fat  in  internal 
organs,  rather  than  overall  body  fat.  In  this  instance,  internal  organ  tissues  become  less 
responsive  to  insulin  signaling  causing  “insulin  resistance,”  one  of  the  earliest  signs  of  diabetes.  In 
additional  animal  studies,  rats  were  given  diabetes  through  a  high  fat  diet  and  were  then  treated 
with arimoclomol. Interestingly, arimoclomol did not prevent overall weight gain by rats fed high fat 
diets, but did lower the fat accumulated in internal organs. 

Based on these very encouraging results, arimoclomol may help prevent the progression of type 2 
diabetes  in  obese  patients  by  warding  off  insulin  resistance.  If  arimoclomol  continues  to  show 
efficacy  in  preclinical  models,  CytRx’s  plan  is  to  seek  a  partnership  for  a  Phase  II  trial  with 
arimoclomol, perhaps in combination with metformin, in type 2 diabetes sometime next year. 

Multiple Indications addressed with Iroxanadine 

Included  in  our  acquisition  last  year  was  the  small  molecule  oral  drug  candidate  iroxanadine.  This 
drug  has  already  been  proven  to  be  well  tolerated  in  three  clinical  safety  trials.  Scientific  data  has 
shown that iroxanadine may help to reduce damage to blood vessels that occurs when blood flow is 
restricted  and  then  restored,  such  as  during  and  immediately  after  heart  attack  and  stroke. 
Researchers  demonstrated  that  iroxanadine  protects  human  endothelial  cells  that  line  the  walls  of 
blood vessels in an in vitro cellular model system of ischemia, a period of oxygen deprivation caused 

 
 
 
by  the  obstruction  of  blood  flow,  followed  by  reperfusion,  or  restoration  of  oxygen  supply.  Normally, 
when oxygen is restored to oxygen-starved endothelial cells the resulting oxidative cell damage triggers 
programmed  cell  death,  known  as  apoptosis,  resulting  in  death  of  the  endothelial  cells.  However, 
published research indicated that cells treated with iroxanadine showed significantly less cell death 
under those conditions, even when the drug was added 20 hours after onset of oxygen deprivation. This 
finding is important because it is believed that stress-induced endothelial cell damage is a crucial step in 
atherosclerosis. 

Cardiovascular clinical trials are typically long in duration and expensive to run. For these reasons, and 
because  we  have  a  number  of  near-term,  less  expensive  late-stage  drug  development  opportunities, 
our  plan  is  to  attempt  to  develop  iroxanadine  for  cardiovascular  indications  through  a  corporate 
partnership. 

Based on iroxanadine’s apparent ability to protect against damage to endothelial cells, we also plan to 
evaluate  its  preclinical  efficacy  for  two  diabetic  complications  that  involve  vascular  dysfunction, 
retinopathy and wound healing. If the drug proves to be efficacious in preclinical work and the FDA 
agrees  that  it  is  appropriate  to  proceed  with  a  Phase  II  clinical  trial,  we  believe  that  a  Phase  II 
clinical trial for either of these indications could begin next year through a corporate partnership. 

HIV Vaccine Program 

CytRx is delighted to report that we are continuing to make progress with the Phase I clinical trial of our 
HIV  vaccine,  and  are  currently  evaluating  patient  immune  responses.  This  vaccine  is  exclusively 
licensed  to  CytRx  by  UMMS  and  ABL  and  early-stage  trials  are  funded  under  a  five-year  $16 million 
HIV Vaccine Design and Development Team contract from the NIAID. 
The primary objective of the Phase I clinical trial is to determine the safety and tolerability of different 
dosages  and  routes  of  administration  of  the  DMA  vaccine,  and  a  fixed  dosage  and  route  of 
administration  of  an  HIV  protein  boost.  The  vaccine  strategy  is  to  assess  in  human  volunteers 
whether  a  DNA  vaccine  with  a  protein  boost  can  stimulate  both  antibody  and  T-cell  immune 
responses to the virus as previously demonstrated in animal models. 

The HIV vaccine formulation created by researchers at UMMS and ABL is a polyvalent vaccine based 
on  multiple  strains  of  HIV  collected  directly  from  infected  people  living  in  different  parts  of  the  world, 
representing five different strains of the virus. The secondary objectives of the trial will test whether the 
approach  can  generate  cross-clade  anti-HIV  immune  response  in  humans.  The  vaccine  contains 
elements  from  selected  HIV  genes,  not  the  live  virus  and,  therefore,  individuals  receiving  inoculations 
are protected against developing HIV from the vaccine. 

RNAi for Drug Development and Discovery 

RNAi  is  a  recently  discovered  technology  that  uses  short  double-stranded  RNA,  or  dsRNA, 
molecules to silence targeted genes and, as a result, is commonly referred to as “gene silencing.” 
RNAi  has  been  shown  to  effectively  silence  targeted  genes  within  living  cells  with  great  specificity 
and  potency.  As  a  result,  RNAi  technology  is  able  to  effectively  silence  targeted  genes  without 
impacting  other,  non-targeted,  genes.  RNAi  is  regarded  as  a  significant  advancement  in  gene 
silencing  and  was  featured  in  Science  magazine  as  the  “Breakthrough  of  the  Year”  in  2002.  RNAi 
can be delivered in vitro and in vivo to target specific messenger RNAs, thus reducing levels of the 
specific protein product coded for by that gene in the targeted cells. This allows the use of RNAi either 
as an effective drug discovery tool or potentially as a therapeutic product itself. 

CytRx  intends  to  develop  RNAi  technology  as  both  a  discovery  tool  to  expedite  the  discovery  of 
classical,  orally-available  small  molecule  drugs  and  for  direct  therapeutic  applications  when 
technically  feasible.  As  a  drug  discovery  tool,  we  intend  to  use  RNAi  to  identify  and  validate  novel 
targets,  which  could  then  be  used  to  discover  small  molecule  therapeutics  for  the  treatment  and 

 
 
 
prevention  of  obesity  and  type  2  diabetes.  As  a  therapeutic,  we  are  funding  pre-clinical  efficacy 
studies  to  determine  whether  to  proceed  with  human  clinical  trials  using  RNAi  to  silence  specific 
genes that cause ALS, CMV retinitis and type 2 diabetes. 

Corporate Events and Updates 

While  we  strengthened  our  technology  base,  we  also  focused  on  rebuilding  our  corporate 
infrastructure  to  support  our  many  programs.  This  included  rounding  out  our  management 
expertise.  We  currently  can  draw  upon  our  senior  managers’  extensive  experience  in 
biopharmaceutical  research  and  development,  legal  and  business  development.  Further,  we 
raised  $21.3  million  in  gross  proceeds  earlier  this  year  to  support  additional  drug  development, 
which  will  provide  sufficient  capital  to  fund  our  currently  planned  operations  and  development 
programs into the second quarter of 2006. 

Our  work  is  supported  by  an  unparalleled  scientific  advisory  board  that  includes  experts  in  the 
fields  of  medicine,  genetics,  biotechnology,  RNAi,  cell  biology,  finance  and  strategic  partnering. 
Among  these  are  a  recipient  of  the  Nobel  Prize  in  Medicine  and  the  co-discoverer  of  RNAi 
technology. 

We  are  also  taking  measures  to  increase  the  visibility  of  CytRx  and  our  potential  in  the 
investment  community.  This  includes  presenting  at  the  BIO  CEO  &  Investors  Conference,  the 
CIBC  World  Markets  15th  Annual  Healthcare  Conference,  the  Rodman  &  Renshaw  Techvest  2nd 
Annual Global Healthcare Conference, and more recently, the UBS Global Pharmaceuticals Conference. 

Looking Forward 

We  believe  that  2005  will  mark  another  year  of  exceptional  progress  for  CytRx.  In  addition  to 
commencing  our  Phase  II  clinical  trial  with  arimoclomol  for  the  treatment  of  Lou  Gehrig’s  disease 
and  evaluating  patients’  immune  response  from  our  HIV  vaccine  Phase  I  trial,  our  plan  is  to 
develop  small  molecule  drug  leads  from  previously  validated  novel  metabolic  disease  targets  and 
pursue  strategic  alliances.  With  funds  to  support  our  studies,  a  dedicated  management  team  and 
world  class  scientists,  we  are  confident  that  we  are  well-positioned  to  move  our  clinical  programs 
forward, develop partnership opportunities and enhance shareholder value. 

In  closing,  we  believe  that  CytRx  is  now  at  the  stage  in  our  clinical  development  in  which  we  are 
entering a period of high value creation for our shareholders. Further, we are doing so through the 
development  of  important  drugs  that  potentially  can  increase  life  expectancy  and  improve  the 
quality  of  life.  On  behalf  of  our  board  of  directors  and  staff  at  CytRx,  we  would  like  to  thank  our 
shareholders for their continued enthusiasm and support and invite you to watch our progress in the 
year ahead. 

Sincerely, 

Steven A. Kriegsman

“SAFE HARBOR” STATEMENT UNDER THE 
PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 

From time to time, we make oral and written statements that may constitute “forward-looking statements” (rather than historical 
facts) as defined in the Private Securities Litigation Reform Act of 1995 or by the Securities and Exchange Commission (the “SEC”) 
in its rules, regulations and releases, including Section 27A of the Securities Act of 1933, as amended (the Securities Act) and Section 
21E of the Securities Exchange Act of 1934, as amended. We desire to take advantage of the “safe harbor” provisions in the Private 
Securities Litigation Reform Act of 1995 for forward-looking statements made from time to time, including, but not limited to, the 
forward-looking statements made in this Annual Report on Form 10-K (the “Annual Report”), as well as those made in other filings 
with the SEC. 

All statements in this Annual Report, including in “Management’s Discussion and Analysis of Financial Condition and Results of 
Operations,”  other  than  statements  of historical  fact  are  forward-looking  statements  for  purposes of  these provisions,  including  any 
projections  of  financial  items,  any  statements  of  the  plans  and  objectives  of  management  for  future  operations,  any  statements 
concerning  proposed  new  products  or  services,  any  statements  regarding  future  economic  conditions  or  performance,  and  any

are  made  as  of  the  date  hereof,  and  we  assume  no  obligation  to  update  any  such  forward-looking  statement  or  reason  why  actual 
results might differ. 

PART I 

Item 1.  Business 

General 

CytRx  Corporation  is  a  biopharmaceutical  research  and  development  company,  based  in  Los  Angeles,  California,  with  an 
operating obesity and type 2 diabetes subsidiary in Worcester, Massachusetts. We are in the process of developing products, primarily 
in the areas of small molecule therapeutics and ribonucleic acid interference, or RNAi, for the human health care market. RNAi is a 
new  technology  for  silencing  genes  in  living  cells  and  organisms.  Our  small  molecule  therapeutics  efforts  include  our  clinical 
development of three, oral drug candidates that we acquired in October 2004, as well as our drug discovery operations conducted in 
the laboratory of our subsidiary. In addition to our work in small molecule therapeutics and RNAi, we are involved in the development 
of a DNA-based HIV vaccine and have entered into strategic alliances with respect to the development of several other products using 
our other technologies. 

Since our incorporation in Delaware 1985, we have been engaged in the development of pharmaceutical products. July 2002, the 
time  of  our  merger  with  Global  Genomics  Capital,  Inc.,  or  Global  Genomics,  marked  a  change  in  the  focus  of  our  company. 
Subsequent to the Global Genomics merger, we modified our corporate business strategy by discontinuing any further research and 
development  efforts  for  our  pre-merger  pharmaceutical  technologies  and  began  to  seek  strategic  relationships  with  other 
pharmaceutical  companies  to  complete  the  development  of  those  technologies.  Instead  of  continuing  research  and  development  for 

 
 
 
 
 
 
 
 
 
 
those technologies, we focused our efforts on acquiring new technologies and products to serve as the foundation for the future of the 
company. 

In  April  2003,  we  acquired  our  first  new  technologies  by  entering  into  exclusive  license  agreements  with  the  University  of 
Massachusetts Medical School, or UMMS, covering potential applications for the medical school’s proprietary RNAi technology in 
the treatment of specified diseases, including those within the areas of obesity and type 2 diabetes; amyotrophic lateral sclerosis, or 
ALS, commonly referred to as Lou Gehrig’s disease, which is a progressive neurodegenerative disease that results in motor neuron 
degeneration of the brain and spinal cord and eventual paralysis; and human cytomegalovirus, or CMV, which is a herpes virus that 
often affects HIV patients. At that time, we also acquired an exclusive license from UMMS covering the medical school’s proprietary 
technology with potential gene therapy applications within the area of cancer. In May 2003, we broadened our strategic alliance with 
UMMS by  acquiring  an  exclusive  license from  that  institution  covering  a proprietary DNA-based HIV vaccine  technology. In July 
2004, we further expanded our strategic alliance with UMMS by entering into a collaboration and invention disclosure agreement with 
UMMS under which UMMS will disclose to us certain new technologies developed at UMMS over the next three years pertaining to 
RNAi, diabetes, obesity, neurodegenerative diseases (including ALS) and CMV and will give us an option, upon making a specified 
payment, to negotiate an exclusive worldwide license to the disclosed technologies on commercially reasonable terms. 

As part of our strategic alliance with UMMS, we agreed to fund certain discovery and pre-clinical research at the medical school 
relating to the use of our technologies, licensed from UMMS, for the development of therapeutic products within certain fields. To 
date, we have entered into agreements with UMMS to sponsor research in the areas of obesity and type 2 diabetes, ALS and CMV 
retinitis. In addition, we have entered into an agreement with Massachusetts General Hospital to sponsor research at that institution 
that will utilize our proprietary gene silencing technology in the area of ALS. 

In conjunction with our work with UMMS, in September 2003, we purchased 95% of CytRx Laboratories, Inc. (formerly known 
as  Araios,  Inc.),  our  research  and  development  subsidiary,  which  had  been  recently  formed  to  develop  small  molecule  and  RNAi-
based therapeutics for the prevention, treatment and cure of obesity and type 2 diabetes. This subsidiary is focusing on using genomic 
and proteomic based drug discovery technologies combined with our proprietary gene silencing technology to accelerate the process 
of screening and identifying potential drug targets and pathways for these diseases. Through this subsidiary, we are seeking to develop 
orally active drugs against promising targets and pathways relevant to obesity and type 2 diabetes. 

On October 4, 2004, we acquired all of the clinical and pharmaceutical and related intellectual property assets of Biorex Research 
&  Development,  RT,  or  Biorex,  a  Hungary-based  company  focused  on  the  development  of  novel  small  molecules  with  broad 
therapeutic applications in neurology, diabetes and cardiology. The acquired assets include three oral, clinical stage drug candidates 
and a library of 500 small molecule drug candidates. The acquisition positions us as a clinical-stage company, as we expect to initiate 
a Phase II trial for ALS with one of our new compounds, arimoclomol, in the second quarter of 2005. 

Although we intend to internally fund or carry out the research and development related to the drug candidates that we acquired 
from  Biorex,  and,  through  our  obesity  and  type  2  diabetes  subsidiary,  the  early  stage  development  work  for  certain  product 
applications based on the RNAi and other technologies that we licensed from UMMS, we may also seek to secure strategic alliances 
or  license  agreements  with  larger  pharmaceutical  companies  to  fund  the  early  stage  development  work  for  other  gene  silencing 
product applications and for subsequent development of those potential products where we fund the early stage development work. 

Prior  to  2003,  our  primary  technologies  consisted  of  Flocor,  an  intravenous  agent  for  treatment  of  sickle  cell  disease  and  other 
acute vaso-occlusive disorders, and TranzFect, a delivery technology for DNA and conventional-based vaccines. In October 2003, we 
entered  into  a  strategic  relationship  with  another  entity,  which  was  recently  formed,  to  complete  the  development  of  Flocor.  Our 
TranzFect  technology  has  been  licensed  to  two  companies.  We  have  granted  a  third  party  an  option  to  license  our  TranzFect 
technology  for  development  as  a  potential  DNA-based  prostate  cancer  adjuvant  and  may  also  seek  to  license  this  technology  as  a 
potential conventional adjuvant for hepatitis C, human pappiloma virus, herpes simplex virus and other viral diseases. Adjuvants are 
agents added to a vaccine to increase its effectiveness. In addition, we may seek to license TranzFect for use as a non-clinical research 
reagent  to  increase  transfection  in  vitro  or  in  laboratory  animals.  Flocor  and  TranzFect  are  further  described  under  “Pre-Global 
Genomics Merger Technologies.” 

In  addition,  through  our  merger  with  Global  Genomics,  we  acquired  minority  interests  in  two  development-stage  genomics 
companies, Blizzard and Psynomics. In 2003, we recorded a write-off of our investments in those companies. Our decision to record 
the write-off was based upon several factors. Those investments, and the write-off of those investments, are further described under 
“Genomics Investments.” 

 
 
 
 
 
 
 
 
 
 
Molecular Chaperone Co-inducers 

The synthesis of proteins is a normal part of every cell’s activity that is essential for life. Proteins are linear chains of building 
blocks  known  as  amino  acids.  In  order  to  function  normally  in  a  cell,  proteins  must  fold  into  particular  three  dimensional  shapes. 
During stressful conditions (e.g. during certain disease states), proteins can fold into inappropriate shapes that result in aggregation of 
proteins, which can be toxic to the cell. As an example, it is believed that mis-folding and aggregation of certain mutated forms of the 
superoxide dismutase 1 (SOD1) protein leads to the death of motor neurons that causes ALS. 

In nature, the cell has developed a way to deal with these potentially toxic mis-folded proteins. Molecular “chaperone” proteins are 
a  key  component  of  a  universal  cellular  protection,  maintenance  and  repair  mechanism  that  helps  ensure  that  newly  synthesized 
proteins  are  complete,  taken  to  the  correct  position  within  the  cell’s  structure,  and  correctly  folded.  Molecular  chaperones  detect 
proteins that are mis-folded, and have the ability to refold those proteins into the appropriate, non-toxic shape. However, if the protein 
is  so  badly  mis-folded  that  it  cannot  be  repaired,  the  molecular  chaperones  also  have  the  ability  to  “tag”  the  toxic  protein  for 
destruction by the cell. This tag, called ubiquitin, directs the mis-folded protein to a cellular apparatus called the proteasome, whose 
function is to degrade the protein into its constituent amino acids for recycling. 

A core element of the cell’s stress-management techniques is known as the heat shock response. Although this response was so-
named because it was initially discovered by subjecting cells to heat stress, it is now known that the heat shock response is generally 
induced by a variety of physical and chemical stresses. As a cell comes under stress, proteins begin to mis-fold into toxic shapes. The 
heat shock response (also referred to as the stress response) increases the synthesis of molecular chaperones that then repair the mis-
folded proteins. 

The stress response can be an important mechanism for cellular survival during certain acute physical stresses. For instance, prior 
induction  of  the  stress  response  can  protect  tissue  culture  cells  from  heat-induced  cell  death.  However,  it  appears  that  the  constant 
stress that occurs as a result of chronic disease dulls the stress response and erodes the effectiveness of the mechanism. For instance, 
although the stress response is slightly induced in the motor neurons of transgenic mice that express the human mutated SOD1 gene 
that causes certain cases of ALS, the level of expression is apparently insufficient to repair the damage and the mice still die from the 
disease. 

We  believe  that  by  boosting  the  stress  response  to  higher  levels,  the  progression  of  chronic  disease  can  be  slowed,  halted  or 
reversed  and  affected  cells  can  be  restored  to  full  functionality.  In  in  vitro  studies,  mammalian  cells  engineered  to  over-express 
molecular  chaperones  have  increased  cross-protection  against  a  variety  of  otherwise  lethal  and  toxic  stresses.  In  in  vivo  studies, 
transgenic mice engineered to over-express a molecular chaperone had improved myocardial function, preserved metabolic function 
and reduced infarct size after ischemia/reperfusion. Increased molecular chaperone expression also significantly increased the lifespan 
in  a  mouse  model  for  spinal  and  bulbar  muscular  atrophy,  a  motor  neuron  disease.  We  believe  that  these  studies  give  substantial 
support within the scientific community for new drugs that are capable of activating a cytoprotective stress response. 

Among the assets recently acquired from Biorex were several drug candidates whose mechanism of action is believed to be the 
“co-induction” of the stress response, meaning that they do not seem to activate the stress response by themselves, but instead they 
amplify  the  production  of  molecular  chaperone  proteins  that  are  already  activated  by  disease-induced  cellular  stress.  These  drug 
candidates thus may selectively amplify molecular chaperone proteins specifically in diseased tissue, which would minimize potential 
drug  side-effects.  The  amplification  of  this  fundamental  protective  mechanism  may  have  powerful  therapeutic  and  prophylactic 
potential, with the potential for an extremely broad field of medical therapeutic utility. 

We believe that the drug candidates acquired from Biorex can potentially improve the cell’s natural capability to resist the toxic 
effects of protein mis-folding, caused by both acute and chronic diseases. Thus, these orally available small molecule drug candidates 
may accomplish the same goals as RNAi, as described below, but accomplish them by repairing or degrading the offending proteins, 
instead of degrading their corresponding mRNAs. Since the specificity for the recognition of mis-folded proteins is an intrinsic feature 
of the amplified molecular chaperones, it is not necessary to identify the actual molecular target of the stress-induced damage. As a 
result, these drug candidates may allow broader therapeutic utility for the removal of damaged proteins compared to that of RNAi. 

We are not aware of other pharmaceutical companies developing small molecule co-inducers of molecular chaperones. At present, 
a  few  potential  drug  candidates  have  been  reported  in  the  literature  to  activate  molecular  chaperone  expression,  but  these  do  not 
require pre-activation of the stress response, and therefore these drug candidates may simply represent a “stress” to the cell. 

 
 
 
 
 
 
 
 
 
 
 
RNAi Technology 

RNAi  technology  is  a  recently  discovered  technology  that  uses  short  double-stranded  RNA,  or  dsRNA,  molecules  to  silence 
targeted  genes  and,  as  a  result,  is  commonly  referred  to  as  “gene  silencing.”  RNAi  has  been  shown  to  effectively  silence  targeted 
genes within living cells with great specificity and potency. As a result, RNAi technology is able to effectively silence targeted genes 
without impacting other, non-targeted, genes. 

RNA  is  a  polymeric  constituent  of  all  living  cells  and  many  viruses,  consisting  of  a  long,  usually  single-stranded  chain  of 
alternating phosphate and ribose units with the bases adenine, guanine, cytosine, and uracil bonded to the ribose. The structure and 
base sequence of RNA are determinants of protein synthesis and the transmission of genetic information. RNAi is a technique of using 
short  pieces  of  double-stranded  RNA  to  precisely  target  the  messenger  RNA,  or  mRNA,  of  a  specific  gene.  The  end  result  is  the 
destruction of the specific mRNA, thus silencing that gene. 

RNAi is regarded as a significant advancement in gene silencing and was featured in Science magazine as the “Breakthrough of 
the Year” in 2002. Delivery of RNAi can be in vitro and in vivo to target specific mRNAs, thus reducing the levels of the specific 
protein product coded for by that gene in the targeted cells. This allows the use of RNAi either as an effective drug discovery tool or 
potentially  as  a  therapeutic  product  itself.  We  intend  to  develop  RNAi  technology  as  both  a  discovery  tool  for  classical,  orally-
available small molecule drugs and for direct therapeutic applications when technically feasible. As a drug discovery tool, we intend 
to use RNAi to identify and validate novel targets, which could then be used to discover small molecule therapeutics for the treatment 
and prevention of obesity and type 2 diabetes. As a therapeutic, we are conducting pre-clinical efficacy studies to determine whether 
to  proceed  with  human  clinical  trials  using  RNAi  to  silence  specific  genes  that  cause  ALS,  CMV  retinitis  and  type  2  diabetes.  In 
January  2004,  Tariq  Rana,  a  scientific  authority  in  delivery  and  stability  of  RNAi,  and  in  March  2004,  Dr.  Craig  Mello,  the  co-
discoverer  of  RNAi,  each  joined  our  Scientific  Advisory  Board  and  they  will  act  in  an  advisory  capacity  to  help  us  develop 
therapeutics for specific diseases. 

In mammals and human cells, gene silencing can be triggered by delivering dsRNA molecules directly into the cell’s cytoplasm 
(the region inside the cell membrane but outside the cell nucleus). Specific enzymes (proteins) in the cell called dicer enzymes cut the 
dsRNA  to  form  small  interfering  RNA,  or  siRNA.  These  siRNA  are  approximately  21  to  25  nucleotide  long  pieces  of  RNA.  The 
siRNA then interact with other cellular proteins to form the RNA-induced silencing complex, or RISC, which causes the unwinding of 
the bound siRNA. This unwound strand of the siRNA can then act as a template to seek out and bind with the complementary target 
mRNA, which carries the coding, or instructions, from the cell nucleus DNA. These instructions determine which proteins the cell will 
produce.  When  the  siRNA-loaded  RISC  binds  with  the  corresponding  mRNA,  that  “message”  is  degraded  and  the  cell  does  not 
produce the specific protein that it encodes. Since the siRNA can be designed to specifically interact with a single gene through its 
mRNA, it can prevent the creation of a specific protein without affecting other genes. 

One  reason  for  the  potential  of  RNAi  to  be  effective,  where  previous  nucleic  acid-based  technologies  have,  to  date,  been 
unsuccessful,  is  that  the  cell  already  has  in  place  all  of  the  enzymes  and  proteins  to  effectively  silence  genes  once  the  dsRNA  is 
introduced into the cell. This is in direct contrast to the older technology of antisense, where there were no known proteins present in 
the cells to facilitate the recognition and binding of the antisense molecule to its corresponding mRNA. 

Another reason for the interest in RNAi is its potential to completely suppress or eliminate the viral replicon. A replicon is a DNA 
or RNA element that can act as a template to replicate itself. Once a virus is established in a cell, there are very few drugs that are 
effective in eliminating the virus. The RNAi process, however, has the potential of eliminating viral nucleic acids and, therefore, to 
cure certain viral diseases. Development work on RNAi is still at an early stage, and we are aware of only two clinical trials using 
RNAi, namely safety trials for age-related macular degeneration by Acuity Pharmaceuticals and Sirna Therapeutics. 

Product Development 

University of Massachusetts Medical School 

Through our strategic alliance with UMMS, we have acquired the rights to a portfolio of technologies, including the rights to use 
UMMS’s  proprietary  RNAi  technology  with  potential  therapeutic  applications  in  certain  defined  areas  that  include  obesity,  type  2 
diabetes, ALS and CMV, as well as a DNA-based HIV vaccine technology and a cancer therapeutic technology. In addition, we have 
entered into a collaboration and invention disclosure agreement with the UMMS under which UMMS will disclose to us certain new 
technologies  developed  at  UMMS  over  the  next  three  years  pertaining  to  RNAi,  diabetes,  obesity,  neurodegenerative  diseases 

 
 
 
 
 
 
 
 
 
 
 
(including ALS) and CMV and will give us an option, upon making a specified payment, to negotiate an exclusive worldwide license 
to the disclosed technologies on commercially reasonable terms. 

The HIV subunit vaccine technology that we have licensed from UMMS is based upon a unique mixture of pieces of human HIV-
1  primary  isolates  from  several  genetic  subtypes  of  HIV.  These  pieces,  called  HIV  envelope  proteins,  are  not  sufficient  for  viral 
replication and therefore cannot lead to accidental infection by HIV. This polyvalent naked DNA (isolated, purified DNA) vaccine 
approach  has  the  potential  advantages  of  maintaining  efficacy  despite  the  high  mutation  rate  of  HIV,  a  broader  immune  response 
against divergent HIV-1 glycoproteins and the possible ability to neutralize a wide spectrum of HIV-1 viruses. UMMS has conducted 
animal studies of this vaccine, and UMMS and Advanced BioScience Laboratories, or ABL, which provides an adjuvant for use with 
the  vaccine,  have  received  a  $16  million  grant  from  the  NIH.  This  grant  is  currently  funding  a  Phase  I  clinical  trial  of  a  vaccine 
candidate using our licensed technology. The investigational new drug application, or IND, for that trial was filed in January 2004 and 
allowed by the FDA to go into effect in March 2004. Enrollment of volunteers for this trial began in April 2004, and we anticipate 
completing  this  trial  in  the  first  half  of  2006.  We  have  a  commercial  relationship  with  ABL  which  gives  us  the  ownership  of,  and 
responsibility for, the further development of the vaccine and subsequent FDA registration following the completion of the Phase I 
trial, which is being conducted by UMMS and ABL. We do not have a commercial relationship with a company that is providing an 
adjuvant  for  the  HIV  vaccine  candidate  in  the  current  Phase  I  clinical  trial.  In  any  future  clinical  development  of  the  vaccine 
candidate,  we  may  be  required  either  to  license  that  adjuvant,  or  use  a  different  adjuvant  in  conjunction  with  our  HIV  vaccine 
technology, in which case we may not be able to utilize some or all of the results of the currently planned trial as part of our clinical 
data for obtaining FDA approval of a vaccine. 

Finally, we have also licensed a cancer treatment technology from UMMS that is based on a naked DNA approach in which the 

DNA material will be delivered by direct injection into the tumor or other localized administration. 

Our  agreements  with  UMMS  may  require  us  to  make  significant  expenditures  to  fund  research  at  the  institution  relating  to 
developing  therapeutic  products  based  on  UMMS’s  proprietary  technologies  that  have  been  licensed  to  us.  We  estimate  that  the 
aggregate  amount  of  these  sponsored  research  expenditures  under  our  current  commitments  will  be  approximately  $1.3  million  for 
2005 and approximately $737,000 for 2006. Our license agreements with UMMS require us to make payments of an aggregate of up 
to $105,000 per year to maintain all of our licenses, with such aggregate annual payments increasing to as much as $145,000 if we are 
not  then  conducting  certain sponsored  research  at  the  institution. Our  UMMS  license agreements  also provide,  in  certain  cases, for 
milestone  payments,  from  us  to  UMMS,  based  on  the  progress  we  make  in  the  clinical  development  and  marketing  of  products 
utilizing the technologies licensed from UMMS. In addition, our license agreements with UMMS require us to reimburse UMMS for 
legal expenses that they incur in prosecuting and maintaining of the related licenses patents. We estimate these legal expenses to be 
approximately $200,000 per year. In the event that we were to successfully develop a product in each of the categories of obesity/type 
2 diabetes, ALS, CMV, cancer and an HIV vaccine, under our licenses, those milestone payments could aggregate up to $16.1 million. 
Those milestone payments, however, could vary significantly based upon the milestones we achieve and the number of products we 
ultimately undertake to develop. In addition, our collaboration and invention disclosure agreement with UMMS requires us to make 
payments  totaling  $750,000  in  2005  in  consideration  for  the  option,  upon  making  a  specified  payment,  to  negotiate  an  exclusive 
worldwide license to certain disclosed technologies. 

Obesity and Type 2 Diabetes 

Obesity and type 2 diabetes are significant health problems. The World Health Organization estimates that, on a worldwide basis, 
there  are  more  than  300  million  cases  of  obesity  and  159  million  cases  of  type  2  diabetes.  According  to  the  American  Obesity 
Association, there are currently more than 60 million cases of obesity in the United States, and the American Diabetes Association 
reports that there are more than 16 million cases of type 2 diabetes in the United States. Scientists at UMMS, as part of our strategic 
alliance,  are  researching,  with  funding  that  we  have  provided,  the  specific  genetic  relationship  of  type  2  diabetes  to  obesity.  The 
research is focused on using cultured adipocytes (fat cells) as a model system for studying the regulation of gene expression involved 
in adipocyte differentiation and function. This research may lead to the identification of specific drug targets which regulate insulin 
signaling as well as other metabolic pathways regulating glucose and fatty acids. With this understanding, the program will focus on 
drug  discovery  of  small  molecule  therapeutics  and  potentially  RNAi-based  therapeutics  for  type  2  diabetes  (e.g.,  drugs  that  act  as 
insulin sensitizers and compounds that alleviate obesity). We believe that RNAi could potentially be a reliable method to selectively 
inhibit certain genes and their corresponding protein expression in adipocytes. 

In May 2004, we licensed from the technology transfer company of the Imperial College of Science, Technology & Medicine the 
exclusive rights to intellectual property covering a drug screening method using RIP 140, which is a nuclear hormone co-repressor that 
is believed to regulate fat accumulation. This proprietary technology is covered by a pending patent application. We paid the licensor a 

 
 
 
 
 
 
 
 
license  fee  in  the  form  of  cash  and  shares  of  our  common  stock,  and  we  will  be  required  to  make  defined  milestone  and  royalty 
payments based on sales of products developed using this technology. We believe this license provides us with an important potential 
drug target in the area of obesity and type 2 diabetes in conjunction with our gene silencing technology. 

In addition, one of the drug candidates acquired from Biorex, iroxanadine, was shown to be well tolerated in two Phase I and one 
Phase II clinical trials and demonstrated significant improvement of vascular function in the brachial artery of hypertensive patients. 
We plan to evaluate the preclinical efficacy of this drug for two diabetic complications that involve vascular dysfunction, retinopathy 
and wound healing. If the drug proves to be efficacious in preclinical work and the FDA agrees that it is appropriate to proceed with a 
Phase II clinical trial, we believe that a Phase II clinical trial for either of these indications could begin in 2006. 

Although we initially intend to develop arimoclomol, another of the drug candidates acquired from Biorex, for the treatment of 
ALS, the drug also showed efficacy in preclinical animal models of diabetes. If efficacy is observed in additional preclinical models, 
we would also consider beginning a Phase II clinical trial for diabetes in 2006, as arimoclomol has already been tested in two Phase I 
clinical trials. 

Research and Development Subsidiary 

In addition to the obesity and diabetes work being done under our sponsored research agreement with UMMS, in September 2003, 
we purchased 95% of CytRx Laboratories, Inc. (formerly known as Araios, Inc.), our research and development subsidiary, which had 
been  recently  formed  by  Dr.  Michael  P.  Czech  to  develop  orally  active  small  molecule  and  RNAi-based  drugs  for  the  prevention, 
treatment  and  cure  of  obesity  and  type  2  diabetes.  Our  business  strategy  is  to  use  our  portfolio  of  state  of  the  art  drug  discovery 
technologies and our relationships with leading diabetes and obesity researchers to discover and develop first in class  medicines to 
prevent,  treat  and  cure  obesity  and  type  2  diabetes.  Utilizing  the  RNAi  target  validation  technology  that  we  have  licensed  from 
UMMS,  in  combination  with  state  of  the  art  target  identification  methods,  our  research  and  development  subsidiary  will  focus  on 
using  a  structure  based  drug  discovery  approach  to  accelerate  the  process  of  screening  and  identifying  potential  drug  targets  and 
pathways for these diseases. Through our subsidiary, we will seek to develop orally administered drugs that are based on promising 
targets and pathways that we may be able to identify. 

Dr. Czech is a prominent scientist in the fields of obesity and type 2 diabetes at UMMS, is a member of our Scientific Advisory 
Board, heads our subsidiary’s Scientific Advisory Board and holds a 5% equity interest in the subsidiary. We provided the subsidiary 
in September 2003 with initial capital of approximately $7,000,000 to fund the staffing of its operations with managerial and scientific 
personnel and its initial drug development activities. 

Through our license and sponsored research agreement with UMMS, we have secured rights to novel drug targets believed to be 
involved in obesity and type 2 diabetes. We will seek to validate these targets using the proprietary high throughput RNAi technology 
that we have licensed from UMMS and will apply state of the art structure-based medicinal chemistry to develop small molecules and 
RNAi-based therapeutic products. 

ALS 

The  development  of  therapeutics  for  the  treatment  of  various  forms  of  ALS  is  an  area  of  significant  interest  for  us.  ALS  is  a 
debilitating disease. According to the ALS Survival Guide, 50% of ALS patients die within 18 months of diagnosis and 80% of ALS 
patients  die  within  five  years  of  diagnosis.  According  to  the  ALS  Association,  in  the  United  States,  alone,  approximately  30,000 
people are living with ALS and nearly 6,000 new cases are diagnosed each year. 

Our drug candidate, arimoclomol, acquired from Biorex in October 2004, was previously shown to be well tolerated in two Phase I 
clinical trials in healthy volunteers. Based on this, and results indicating efficacy of the drug candidate in animal models of neuronal 
damage, including the published efficacy data of the drug in animal models of ALS, we expect to begin a Phase II clinical trial with 
arimoclomol for the treatment of ALS in the second quarter of 2005. We are scheduled to discuss the proposed Phase II clinical trial 
with the FDA in the coming weeks. 

In October 2003, we entered into sponsored research agreements with UMMS and Massachusetts General Hospital, pursuant to 
which we will sponsor certain ALS research at those institutions utilizing our proprietary gene silencing technology targeted at the 
mutant SOD1 gene, which is the subject of the ALS technology we have licensed from UMMS. The mutant SOD1 gene is responsible 
for causing ALS in a subset of the 10% of all ALS patients who suffer from the familial, or genetic, form of the disease. 

 
 
 
 
 
 
 
 
 
 
 
 
 
Dr. Zuoshang Xu, an Associate Professor of Biochemistry and Molecular Pharmacology at UMMS, is the principal investigator 
under  our  sponsored  research  agreement  with  UMMS.  We  have  funded  approximately  $302,000  of  research  under  that  agreement 
during its first year, and have committed to fund approximately $280,000 of research under that agreement during its second year and 
approximately $288,000 of research under that agreement during the third year of the program. 

Dr.  Robert  B.  Brown,  Jr.,  a  Professor  of  Neurology  at  Harvard  Medical  School,  Founder  and  Director  of  the  Cecil  B.  Day 
Laboratory  for  Neuromuscular  Research  and  a  co-discoverer  of  the  mutant  SOD1  gene  as  a  cause  for  certain  ALS  cases,  is  the 
principal investigator under our sponsored research agreement with Massachusetts General Hospital. Under the agreement, we have 
agreed to fund approximately $487,000 of sponsored research at Massachusetts General Hospital through the end of 2005. In March 
2004, Dr. Brown joined our Scientific Advisory Board and entered into a consulting agreement with us. 

Cardiovascular Disease 

Preclinical results by third parties with our drug candidate, iroxanadine, indicate that it has therapeutic potential for the treatment 
of  cardiovascular  atherosclerosis.  If  iroxanadine  proves  to  be  effective  in  additional  preclinical  work,  we  plan  to  seek  a  strategic 
alliance with a larger company to support the subsequent clinical development for this indication. 

Pre-Global Genomics Merger Technologies 

Therapeutic Copolymer Program 

Prior  to  the  merger  with  Global  Genomics,  our  primary  focus  was  on  CRL-5861  (purified  poloxamer  188),  which  we  also  call 
Flocor.  Flocor  is  an  intravenous  agent  for  the  treatment  of  sickle  cell  disease  and  other  acute  vaso-occlusive  disorders.  Sickle  cell 
disease  is  an  inherited  disease  caused  by  a  genetic  mutation  of  hemoglobin  in  the  blood,  and  acute  vaso-occlusive  disorders  are  a 
blockage of blood flow caused by deformed, or “sickled,” red blood cells which can cause intense pain in sickle cell disease patients. 
In June 2004, we licensed our copolymer technologies, including Flocor, on an exclusive basis, to SynthRx, Inc., a Houston, Texas-
based biopharmaceutical company. As a result of the SynthRx license, we received a 19.9% ownership interest in SynthRx and a cash 
payment  from  SynthRx  of  approximately  $228,000,  in  return  for  our  rights  to  the  licensed  technologies.  In  addition,  upon 
commercialization of any products developed under our alliance with SynthRx, we may also receive significant milestone payments 
and royalties. Prior to the change in our business strategy that led us to seek licensees for our Flocor technology, we had internally 
developed Flocor. In December 1999, we reported results from a Phase III clinical study of Flocor for treatment of acute sickle cell 
crisis. Although the study did not demonstrate statistical significance in the primary endpoint, or objective, of the study, statistically 
significant  and  clinically  important  benefits  associated  with  Flocor  were  observed  in  certain  subgroups.  All  amounts  paid  to  us  by 
SynthRx are non-refundable upon termination of the agreement and require no additional effort on our part. 

Vaccine Enhancement and Gene Therapy 

Gene therapy and gene-based vaccines are mediated through the delivery of DNA containing selected genes into cells by a process 
known as transfection. We refer to our gene delivery technology as TranzFect. A large majority of the revenues we have generated 
over the past three years has been due to license fees paid to us with respect to our TranzFect technology, representing 93%, 81% and 
94% of our total revenues for 2004, 2003 and 2002, respectively. 

Merck License 

In November 2000, we entered into an exclusive, worldwide license agreement with Merck & Co., Inc. whereby we granted Merck 
the  right  to  use  our  TranzFect  technology  in  DNA-based  vaccines  for  HIV  and  three  other  targets.  To  date,  Merck  has  focused  its 
efforts on the HIV application, which is still at an early stage of clinical development, and, in July 2003, Merck notified us that it was 
returning to us the rights to the three other targets covered by its license, which we are now able to license to other third parties. In 
November 2000, Merck paid us a signature payment of $2 million. In February 2002, we received an additional $1 million milestone 
fee  related  to  the  commencement  of  Merck’s  first  FDA  Phase  I  study  for  a  product  incorporating  TranzFect  designed  for  the 
prevention  and  treatment  of  HIV.  Merck  completed  a  multi-center,  blinded,  placebo  controlled  Phase  I  trial  of  an  HIV  vaccine 
utilizing TranzFect as a component. Although the formulation of this tested vaccine was generally safe, well-tolerated and generated 
an  immune  response,  the  addition  of  TranzFect  to  the  vaccine  did  not  increase  this  immune  response.  Moreover,  the  DNA  single- 
modality vaccine regimen with TranzFect, when tested in humans, yielded immune responses that were inferior to those obtained with 
the DNA vaccines in macaque monkeys. All amounts paid to us by Merck are non-refundable upon termination of the agreement and 
require no additional effort on our part. 

 
 
 
 
 
 
 
 
 
 
 
 
Vical License 

In December 2001, we entered into a license agreement with Vical Incorporated granting Vical exclusive, worldwide rights to use 
or sublicense our TranzFect poloxamer technology to enhance viral or non-viral delivery of polynucleotides, such as DNA and RNA, 
in  all  preventive  and  therapeutic  human  and  animal  health  applications,  except  for  (1)  the  four  targets  previously  licensed  by us to 
Merck,  (2)  DNA  vaccines  or  therapeutics  based  on  prostate-specific  membrane  antigen,  or  PSMA,  and  (3)  sale  of  a  non-regulated 
product  for  use  as  a  non-clinical  research  reagent  to  increase  transfection  in  vitro  or  in  laboratory  animals.  In  addition,  the  Vical 
license permits Vical to use TranzFect poloxamer technology to enhance the delivery of proteins in prime-boost vaccine applications 
that involve the use of polynucleotides (short segments of DNA or RNA). Under the Vical license, we received a non-refundable up-
front payment of $3,750,000, and, in addition to annual maintenance payments, we have the potential to receive milestone and royalty 
payments in the future based on criteria described in the agreement. In April 2004, we received an additional $100,000 milestone fee 
related  to  the  commencement  of  Vical’s  first  FDA  Phase  I  clinical  trial  for  a  product  incorporating  our  TranzFect  technology.  All 
amounts paid to us by Vical are non-refundable upon termination of the agreement and require no additional effort on our part. 

2002 Merger with Global Genomics 

On  July  19,  2002,  we  completed  the  acquisition  of  Global  Genomics.  The  acquisition  of  Global  Genomics  was  accomplished 
through a merger of our wholly-owned subsidiary, GGC Merger Corporation, with and into Global Genomics. Global Genomics was 
the surviving corporation in the merger with GGC Merger Corporation and is now our wholly-owned subsidiary. We have changed 
Global  Genomics’  name  to  GGC  Pharmaceuticals,  Inc.,  but  for  purposes  of  this  Annual  Report,  we  will  continue  to  refer  to  the 
company as Global Genomics. For accounting purposes, we were deemed the acquiror of Global Genomics. 

In the Global Genomics merger, each outstanding share of common stock of Global Genomics was converted into 0.765967 shares 
of our common stock. Accordingly, a total of 8,948,204 shares of our common stock, or approximately 41.7% of our common stock 
outstanding immediately after the merger, were issued to the common stockholders of Global Genomics, and an additional 1,014,677 
shares  of  our  common  stock  were  reserved  for  issuance  upon  the  exercise  of  the  outstanding  Global  Genomics  warrants  that  we 
assumed in the merger. Other than the foregoing stock, we paid no other consideration to the Global Genomics shareholders. 

At  the  time  of  the  Global  Genomics  merger,  there  were  no  material  relationships  between  Global  Genomics  or  any  of  its 
shareholders or affiliates and us, except that on July 16, 2002, Global Genomics’ three designees to our board of directors, Steven A. 
Kriegsman,  Louis  J.  Ignarro,  Ph.D.  and  Joseph  Rubinfeld,  Ph.D.,  were  elected  directors  and  Mr.  Kriegsman  became  our  Chief 
Executive Officer. Mr. Kriegsman was Global Genomics’ Chairman and Dr. Ignarro was a director of Global Genomics at that time. 
On the date of the merger, the controlling shareholder of Global Genomics was Mr. Kriegsman, who beneficially owned, on a fully 
diluted basis, approximately 40.4% of Global Genomics’ equity interests. 

Genomics Investments 

In connection with our merger with Global Genomics, we acquired indirectly equity interests in two development-stage genomics 
companies, a 40% equity interest in Blizzard and a 5% equity interest in Psynomics. In the fourth quarter of 2003, we decided that we 
would cease funding our investments in those genomics companies to focus on our core strategy of developing human therapeutics for 
large market indications. In May 2004, we determined that a write-off of those investments in the third quarter of 2003 should have 
been  made.  Our  decision  to  record  the  write-off  was  based  upon  several  factors,  including  Blizzard’s  lack  of  success  in  raising  a 
significant  amount  of  the  financing  necessary  for  it  to  pursue  the  commercialization  strategy  for  its  products,  current  financial 
projections prepared by Blizzard, application of a discounted cash flow valuation model of Blizzard’s projected cash flows and the 
consideration of other qualitative factors. Based upon the quantitative and qualitative factors described above, in addition to others, we 
determined that the investment in Blizzard had no remaining value as of September 30, 2003 and that a write-off of this investment 
should have been made in the third quarter of 2003. It is our understanding that, by the end of 2003, Blizzard had ceased operations 
and was in the process of returning its licensed intellectual property to the University of Minnesota. 

Research and Development Expenditures 

Expenditures  for  research  and  development  activities  related  to  continuing  operations  were  $9.0  million,  $4.4  million  and 
$767,000 during the years ended December 31, 2004, 2003 and 2002, respectively. Included in research and development expenses for 
2004 was $3.0 million of in-process research and development that was written off in conjunction with our acquisition of assets from 
Biorex. 

 
 
 
 
 
 
 
 
 
 
 
 
Manufacturing 

We do not have the facilities or expertise to manufacture any of the clinical or commercial supplies of any of our products. To be 
successful,  our  products  and  the  products  of  our  partners  must  be  manufactured  in  commercial  quantities  in  compliance  with 
regulatory requirements and at an acceptable cost. To date, we have not commercialized any products, nor have we demonstrated that 
we  can  manufacture  commercial  quantities  of  our  product  candidates  in  accordance  with  regulatory  requirements.  If  we  cannot 
manufacture products in suitable quantities and in accordance with regulatory standards, either on our own or through contracts with 
third parties, it may delay clinical trials, regulatory approvals and marketing efforts for such products. Such delays could adversely 
affect our competitive position and our chances of achieving profitability. We cannot be sure that we can manufacture, either on our 
own or through contracts with third parties, such products at a cost or in quantities, which are commercially viable. We currently rely 
and  intend  to  continue  to  rely  on  third-  party  contract  manufacturers  to  produce  materials  needed  for  research,  clinical  trials  and, 
ultimately, for product commercialization. 

Patents and Proprietary Technology 

We actively seek patent protection for our technologies, processes, uses, and ongoing improvements and consider our patents and 
other  intellectual  property  to be  critical  to  our  business. We  have filed  applications for  a number of patents  and have been granted 
patents related to technologies, primarily TranzFect and Flocor, we were developing prior to our 2002 merger with Global Genomics. 
Subsequent to the merger, we acquired patents in connection with our acquisition of intellectual property rights of Biorex and we have 
licensed additional technologies covered by patents or patent applications, most of which are in the RNAi field. 

As part of our development  process, we evaluate the patentability of new inventions and improvements developed by us or our 
collaborators. Whenever appropriate, we will endeavor to file United States and international patent applications to protect these new 
inventions  and  improvements.  However,  we  cannot  be  certain  that  any  of  the  current  pending  patent  applications  we  have  filed  or 
licensed, or any new patent applications we may file or license, will ever be issued in the United States or any other country. Even if 
issued, there can be no assurance that those patents will be sufficiently broad to prevent others from using our products or processes. 
Furthermore, our patents, as well as those we have licensed or may license in the future, may be held invalid or unenforceable by a 
court, or third parties could obtain patents that we would need to either license or to design around, which we may be unable to do. 
Current and future competitors may have licensed or filed patent applications or received patents, and may acquire additional patents 
and proprietary rights relating to small molecule technology, RNAi technology, DNA-based vaccines or other compounds, products or 
processes competitive with ours. 

In addition to patent protection, we also attempt to protect our proprietary products, processes and other information by relying on 
trade  secrets  and  non-disclosure  agreements  with  our  employees,  consultants  and  certain  other  persons  who  have  access  to  such 
products,  processes  and  information.  Under  the  agreements,  all  inventions  conceived  by  employees  are  our  exclusive  property. 
Nevertheless,  there  can  be  no  assurance  that  these  agreements  will  afford  significant  protection  against  misappropriation  or 
unauthorized disclosure of our trade secrets and confidential information. 

Competition 

Currently,  Rilutek(R),  which  was  developed  by  Aventis  Pharma  AG,  is  the  only  drug  of  which  we  are  aware  that  has  been 
approved  by  the  FDA  for  the  treatment  of  ALS.  Other  companies  are  working  to  develop  pharmaceuticals  to  treat  ALS,  including 
Aeolus  Pharmaceuticals  and  Oxford  BioMedica  plc.  In  addition,  ALS  belongs  to  a  family  of  diseases  called  neurodegenerative 
diseases,  which  includes  Alzheimer’s,  Parkinson’s  and  Huntington’s  disease.  Due  to  similarities  between  these  diseases,  a  new 
treatment for one ailment potentially could be useful for treating others. There are many companies that are producing and developing 
drugs  used  to  treat  neurodegenerative  diseases  other  than  ALS,  including  Amgen,  Inc.,  Guilford  Pharmaceuticals,  Phytopharm  plc, 
Cephalon, Inc. and Ceregene, Inc. 

The RNAi field, though at an early stage of development, is already a competitive one and the competition is expected to increase. 
We  face  competition  on  many  fronts  —  ranging  from  large  and  small  pharmaceutical,  chemical  and  biotechnology  companies  to 
universities, government agencies and other public and private research organizations. Examples of companies that are focusing their 
commercial  efforts  in  the  RNAi  field  are  Sirna  Therapeutics,  Alnylam  Pharmaceuticals  and  Benitec  Ltd.  A  number  of  the 
multinational pharmaceutical companies also either have their own gene silencing product development programs or are working with 
smaller biopharmaceutical companies in this area. In addition to our RNAi competitors, companies in other fields may be using other 
technologies to target the same diseases that we are targeting. The competition from other firms and institutions will manifest itself not 

 
 
 
 
 
 
 
 
 
 
 
only in our potential product  markets but also, and importantly at this stage in development of RNAi technology, in recruiting and 
retaining key scientific and management personnel. 

Companies  developing  HIV  vaccines  that  could  compete  with  our  HIV  vaccine  technology  include  Merck,  VaxGen,  Inc., 
Epimmune, Inc., AlphaVax, Inc. and Immunitor Corporation, and ABL may also seek to develop competing HIV vaccines that could 
utilize a portion of the technology that we have licensed from UMMS and ABL. 

With respect to both our RNAi and non-RNAi products, many companies, including large pharmaceutical and biotechnology firms 
with financial resources, research and development staffs, and facilities that may, in certain cases, be substantially greater than those 
of  ours  or  our  strategic  partners  or  licensees,  are  engaged  in  the  research  and  development  of  pharmaceutical  products  that  could 
compete  with  our  potential  products.  To  the  extent  that  we  seek  to  acquire,  through license  or otherwise,  existing  or potential  new 
products, we will be competing with numerous other companies, many of which will have substantially greater financial resources, 
large acquisition and research and development staffs that may give those companies a competitive advantage over us in identifying 
and  evaluating  these  drug  acquisition  opportunities.  Any  products  that  we  acquire  will  be  competing  with  products  marketed  by 
companies that in many cases will have substantially greater marketing resources than we have. The industry is characterized by rapid 
technological advances and competitors may develop their products more rapidly and such products may be more effective than those 
currently under development or that may be developed in the future by our strategic partners or licensees. Competitive products for a 
number  of  the  disease  indications  that  we  have  targeted  are  currently  being  marketed  by  other  parties,  and  additional  competitive 
products are under development and may also include products currently under development that we are not aware of or products that 
may be developed in the future. 

Government Regulation 

The  marketing  of  pharmaceutical  products  requires  the  approval  of  the  FDA  and  comparable  regulatory  authorities  in  foreign 
countries.  The  FDA  has  established  guidelines  and  safety  standards  which  apply  to  the  pre-clinical  evaluation,  clinical  testing, 
manufacture  and  marketing  of  pharmaceutical  products.  The  process  of  obtaining  FDA  approval  for  a  new  drug  product  generally 
takes  a  number  of  years  and  involves  the  expenditure  of  substantial  resources.  The  steps  required  before  such  a  product  can  be 
produced and marketed for human use in the United States include preclinical studies in animal models, the filing of an Investigational 
New Drug (IND) application, human clinical trials and the submission and approval of a New Drug Application (NDA) or a Biologics 
License  Application  (BLA).  The  NDA  or  BLA  involves  considerable  data  collection,  verification  and  analysis,  as  well  as  the 
preparation of summaries of the manufacturing and testing processes, preclinical studies, and clinical trials. The FDA must approve 
the NDA or BLA before the drug may be marketed. There can be no assurance that we or our strategic alliance partners or licensees 
will be able to obtain the required FDA approvals for any of our products. 

The manufacturing facilities and processes for our products, which we anticipate will be manufactured by our strategic partners or 
licensees or other third parties, will be subject to rigorous regulation, including the need to comply with Federal Good Manufacturing 
Practice  regulations.  Our  manufacturers  also  will  be  subject  to  regulation  under  the  Occupational  Safety  and  Health  Act,  the 
Environmental  Protection  Act,  the  Nuclear  Energy  and  Radiation  Control  Act,  the  Toxic  Substance  Control  Act  and  the  Resource 
Conservation and Recovery Act. 

Employees 

As of December 31, 2004, we had 23 full-time employees, 14 of whom were engaged in research and development activities and 
nine  of  whom  were  involved  in  management  and  administrative  operations.  All  of  the  employees  engaged  in  research  and 
development activities hold Ph.D. degrees, and one also holds an M.D. degree. 

Item 2.  Properties 

Our operations are based in Los Angeles, California, and Worcester, Massachusetts. The lease for our headquarters facility in Los 
Angeles covers approximately 3,300 square feet of office space and expires in June 2005. We are currently considering renewing the 
lease  or  alternatively  locating  substantially  similar,  alternative  office  space.  The  lease  for  our  subsidiary  in  Worcester  covers 
approximately 6,900 square feet of office and laboratory space and expires in December 2005. Our facilities are suitable and adequate 
for our current operations. We have the right to extend the Worcester lease until December 2007. 

 
 
 
 
 
 
 
 
 
 
 
 
Item 3.  Legal Proceedings 

We are occasionally involved in claims arising out of our operations in the normal course of business, none of which are expected, 

individually or in the aggregate, to have a material adverse effect on us. 

In February 2004, we were notified by the Massachusetts State Ethics Commission, or the Massachusetts Commission, that it had 
initiated  a  preliminary  inquiry  into  whether  our  previous  retention  of  a  consultant  who  introduced  us  to  UMMS  constituted  an 
improper conflict of interest under Massachusetts’ ethics laws. UMMS has advised us that it continues to believe that its agreements 
with  us  provided  excellent  value  for  UMMS,  that  it  anticipates  that  the  Massachusetts  Commission’s  review  of  the  terms  of  those 
agreements will confirm that the agreements were fair to UMMS, and that it believes that the Massachusetts Commission will concur 
with the resolution of the conflict proposed by UMMS under which the consultant will forfeit to UMMS certain of the compensation 
that the consultant was to receive from us. 

Item 4.  Submission of Matters to a Vote of Security Holders

In the fourth quarter of 2004, we completed our acquisition of all of the clinical, pharmaceutical and related intellectual property 
assets of Biorex, a Hungary-based company focused on the development of novel small molecules with broad therapeutic applications 
in neurology, diabetes and cardiology. We paid Biorex $3.0 million in cash for the assets at the closing, and incurred approximately 
$500,000 in expenses related to the transaction. 

The assets acquired from Biorex include three drug candidates that had completed the equivalent of a Phase I clinical trial. We 
intend  to  perform  additional  testing  on  those  drug  candidates,  and  expect  to  initiate  a  Phase  II  clinical  trial  for  one  of  the  drug 
candidates, arimoclomol, for ALS in the second quarter of 2005. In addition, we acquired a 500-compound molecular library, which 
we plan to use in high throughput screening at our obesity and diabetes laboratory. With the assistance of an outside appraiser, we 
evaluated the technology assets acquired from Biorex, including their current state of development, the severability of the assets, and 
alternative uses of the compounds. Based in part on that appraisal, we concluded that the $3.0 million value allocated to the three drug 
candidates  should  be  written  off  at  the  time  of  acquisition  as  in-process  research  and  development,  and  that  the  $500,000  value 
attributable to the 500-compound molecular library should be included in our fixed assets at December 31, 2004. 

In the third quarter of 2003, we recorded an impairment charge of $5.9 million related to our investments in Blizzard’s acquired 
developed  technology  and  in  Psynomics,  based  upon  our  analysis  of  the  recoverability  of  the  carrying  amount  of  these  assets  in 
accordance  with  the  Accounting  Principles Board  Opinion  No.  18,  The  Equity  Method  of  Accounting  for  Investments  in  Common 
Stock.  This  impairment  charge  represented  the  total  net book value  of  these  assets  at  the  time  of  the  write-off. See  Note 12  to our 
audited financial statements. 

In 2002, we recorded an impairment charge of $921,000 related to certain equipment and leasehold improvements based on our 
evaluation of the recoverability of the carrying amount of those assets in accordance with the Financial Accounting Standards Board, 
or FASB, Statement of Financial Accounting Standards No. 144 — Accounting for the Impairment or Disposal of Long-Lived Assets. 
This impairment charge represented the total net book value of those assets. See Note 6 to our audited financial statements. 

 
 
 
  
  
  
  
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
  
 
 
 
  
 
 
  
 
 
 
 
  
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
  
  
 
  
 
 
 
 
 
During 2002, we recorded a loss of $478,000 associated with the closure of our Atlanta headquarters and relocation to Los Angeles 
subsequent to our merger with Global Genomics. This loss represents the total remaining lease obligations and estimated operating 
costs through the remainder of the lease, which expires in 2008, less estimated sublease income. This accrued charge was combined 
with  deferred  rent  of  $85,000  already  recorded,  so  that  the  total  accrual  related  to  the  facility  abandonment  was  $563,000  as  of 
December 31, 2002. To the extent that we are able to negotiate a termination of the Atlanta lease, our operating costs are different or 
our estimates related to sublease income are different, the total loss ultimately recognized may be different than the amount recorded 
as of December 31, 2002 and such difference may be material. As of December 31, 2004 and 2003, we had remaining lease closure 
accruals of $312,000 and $418,000, respectively. 

Pursuant to his employment agreement, our former President and Chief Executive Officer, Jack Luchese, was entitled to a payment 
of  $435,000  upon  the  execution  of  the  merger  agreement  between  Global  Genomics  and  us  and  an  additional  $435,000  upon  the 
closing  of  the  merger.  In  order  to  reduce  the  amount  of  cash  that  we  had  to  pay  Mr.  Luchese,  Mr.  Luchese  and  we  agreed  that 
approximately  $325,000 of the first $435,000 payment would be satisfied by our grant to Mr. Luchese under our 2000 Long-Term 
Incentive Plan pursuant of an award of 558,060 shares of our common stock. Those shares of stock were issued at a value equal to 
85%  of  the  volume  weighted  average  price  of  our  common  stock  for  the  20  trading  days  ended  on  February  8,  2002.  The  cash 
payment and fair value of the shares issued were recognized as expense (total of $428,000) during the first quarter of 2002. 

The  terms  of  our  merger  with  Global  Genomics  contemplated  that  its  management  team  would  replace  ours  subsequent  to  the 
closing  of  the  merger.  On  July  16,  2002,  we  terminated  the  employment  of  all  of  our  then-current  officers,  resulting  in  total 
obligations for severance, stay bonuses, accrued vacation and other contractual payments of $1.4 million (including the final $435,000 
owed to Mr. Luchese as discussed above). Prior to the merger closing date, we advanced part of these amounts to three of our officers 
(through salary continuance), such that the total remaining obligation at the closing date was $1.2 million. Four of our officers agreed 
to accept an aggregate total of $177,000 of this amount in the form of our common stock, in lieu of cash, resulting in the issuance of 
248,799 shares. Thus, the net cash payout in satisfaction of these obligations was $1.0 million, before taxes. The severance payments 
and fair value of the shares issued (total  expense of $1.4 million) were recognized as expense during the third quarter of 2002 and 
reported  as  a  separate  line  item  on  the  accompanying  consolidated  statement  of  operations,  together  with  the  final  payment  to  Mr. 
Luchese discussed above. 

License fees for 2002 include a $1.0 million milestone payment received from Merck related to the commencement by Merck of a 

Phase I human clinical trial incorporating our TranzFect technology. 

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

The  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  should  be  read  together  with  the 
discussion under “Selected Financial Data” and our consolidated financial statements included in this Annual Report. This discussion 
contains forward-looking statements, based on current expectations and related to future events and our future financial performance, 
that  involve  risks  and  uncertainties.  Our  actual  results  may  differ  materially  from  those  anticipated  in  these  forward-looking 
statements as a result of many important factors, including those set forth under “Risk Factors” and elsewhere in this Annual Report. 

Overview 

We  are  in  the  process  of  developing  products,  primarily  in  the  areas  of  small  molecule  therapeutics  and  ribonucleic  acid 
interference, or RNAi, for the human health care market. RNAi is a new technology for silencing genes in living cells and organisms. 
Development work on RNAi is still at an early stage, and we are aware of only two clinical tests of medical applications using RNAi 
that have yet been initiated by any party. Our small molecule therapeutics efforts include our clinical development of three, oral drug 
candidates that we acquired in October 2004, as well as our drug discovery operations conducted at CytRx Laboratories. In addition to 
our  work  in  RNAi  and  small  molecule  therapeutics,  we  are  involved  in  the  development  of  a  DNA-based  HIV  vaccine  and  have 
entered into strategic alliances with respect to the development of several other products using our other technologies. 

Subsequent to our merger with Global Genomics, in July 2002, we modified our business strategy by discontinuing any further 
research and development efforts for our pre-merger pharmaceutical technologies and began to seek strategic relationships with other 
pharmaceutical  companies  to  complete  the  development  of  those  technologies.  Instead  of  continuing  research  and  development  for 
those technologies, we focused our efforts on acquiring new technologies and products to serve as the foundation for the future of the 
company. 

 
 
 
 
 
 
 
 
 
 
 
 
In  April  2003,  we  acquired  our  first  new  technologies  by  entering  into  exclusive  license  agreements  with  the  University  of 
Massachusetts  Medical  School,  or  UMMS,  covering  potential  applications  for  its  proprietary  RNAi  technology  in  the  treatment  of 
specified diseases. At that time, we also acquired an exclusive license from UMMS covering its proprietary technology with potential 
gene therapy applications within the area of cancer. In May 2003, we broadened our strategic alliance with UMMS by acquiring an 
exclusive license from it covering a proprietary DNA-based HIV vaccine technology. In July 2004, we further expanded our strategic 
alliance  with  UMMS  by  entering  into  a  collaboration  and  invention  disclosure  agreement  with  UMMS  under  which  UMMS  will 
disclose  to  us  certain  new  technologies  developed  at  UMMS  over  the  next  three  years  pertaining  to  RNAi,  diabetes,  obesity, 
neurodegenerative  diseases  (including  amyotrophic  lateral  sclerosis,  also  known  as  Lou  Gehrig’s  disease  or  ALS)  and 
cytomegalovirus, or CMV, and will give us an option, upon making a specified payment, to negotiate an exclusive worldwide license 
to the disclosed technologies on commercially reasonable terms. 

As part of our strategic alliance with UMMS, we agreed to fund certain discovery and pre-clinical research at the medical school 
relating  to  the  use  of  our  technologies,  licensed  from  UMMS,  for  the  development  of  therapeutic  products  within  certain  fields. 
Although we  intend  to  internally  fund  the  early  stage  development  work  for  certain product  applications (including  obesity,  type 2 
diabetes and ALS) and may seek to fund the completion of the development of certain of these product applications (such as ALS), we 
may  also  seek  to  secure  strategic  alliances  or  license  agreements  with  larger  pharmaceutical  companies  to  fund  the  early  stage 
development work for other gene silencing product applications and for subsequent development of those potential products where we 
fund the early stage development work. 

On October 4, 2004, we acquired all of the clinical and pharmaceutical and related intellectual property assets of Biorex Research 
&  Development,  RT,  or  Biorex,  a  Hungary-based  company  focused  on  the  development  of  novel  small  molecules  with  broad 
therapeutic applications in neurology, diabetes and cardiology. The acquired assets include three oral, clinical stage drug candidates 
and a library of 500 small molecule drug candidates. The acquisition positions us as a clinical-stage company, as we expect to initiate 
a Phase II trial for ALS with one of our new drug candidates, arimoclomol, in the second quarter of 2005. 

We have not achieved profitability on a quarterly or annual basis and we expect to continue to incur significant additional losses 
over the next several years. Our net losses may increase from current levels primarily due to activities related to our collaborations, 
technology acquisitions, research and development programs and other general corporate activities. We anticipate that our operating 
results will fluctuate for the foreseeable future. Therefore, period-to-period comparisons should not be relied upon as predictive of the 
results in future periods. 

To  date,  we  have  relied  primarily  upon  the  sale  of  equity  securities  and,  to  a  lesser  extent,  upon  payments  from  our  strategic 
partners and licensees to generate the funds needed to finance the implementation of our business plans. We will be required to obtain 
additional funding in order to execute our long-term business plans. Our sources of potential funding for the next several years are 
expected  to  consist  primarily  of  proceeds  from  sales  of  equity,  but  could  also  include  license  and  other  fees,  funded  research  and 
development payments, and milestone payments under existing and future collaborative arrangements. 

Research and Development 

Following our 2003 acquisition of rights from UMMS to the new technologies, we initiated research and development programs 
for  products  based  upon  those  technologies.  Expenditures  for  research  and  development  activities  related  to  continuing  operations 
were $9.0 million, $4.4 million and $767,000 for the years ended December 31, 2004, 2003 and 2002, respectively, with research and 
development expenses representing approximately 53%, 39% and 11% of our total expenses for the years ended December 31, 2004, 
2003  and 2002, respectively.  Included  in research  and  development  expenses for  2004  was  $3.0  million  of  in-process  research  and 
development that was written off in conjunction with our acquisition of assets from Biorex. Research and development expenses are 
further discussed below under “Critical Accounting Policies and Estimates” and “Results of Operations.” 

In  September  2003,  we  purchased  95%  of  CytRx  Laboratories,  Inc.  (formerly  known  as  Araios,  Inc.),  our  research  and 
development  subsidiary,  which  had  been  recently  formed  to  develop  orally  active  small  molecule-based  drugs  for  the  prevention, 
treatment and cure of obesity and type 2 diabetes. Utilizing the RNAi technology that we have licensed from UMMS, in combination 
with state of the art target identification methods, our subsidiary will focus on using a genomic and proteomic based drug discovery 
approach to accelerate the process of screening and identifying potential drug targets and pathways for these diseases to discover and 
develop molecular based medicines for the treatment of obesity and type 2 diabetes. We provided our subsidiary in September 2003 
with initial capital of approximately $7,000,000 to fund the staffing of its operations with managerial and scientific personnel and its 
initial drug development activities. 

 
 
 
 
 
 
 
 
 
 
In  October  2004,  we  acquired  all  of  the  clinical,  pharmaceutical  and  related  intellectual  property  assets  of  Biorex,  a  company 
focused on the development of novel small molecules with broad therapeutic applications in neurology, diabetes and cardiology. The 
acquired assets include three oral, clinical stage drug candidates and a library of 500 small molecule drug candidates. We expect to 
initiate a Phase II trial for ALS with one of the compounds, arimoclomol, in the second quarter of 2005, and estimate that the Phase II 
trial  will  require  us  to  expend  approximately  $5.5  million  over  a  period  of  twelve  to  eighteen  months,  which  includes  a  $500,000 
milestone payment that may become payable to Biorex under certain circumstances. 

There is a risk that any drug discovery and development program may not produce revenue because of the risks inherent in drug 
discovery  and  development.  Moreover,  there  are  uncertainties  specific  to  any  new  field  of  drug  discovery,  including  RNAi.  The 
successful development of any product candidate we develop is highly uncertain. We cannot reasonably estimate or know the nature, 
timing and costs of the efforts necessary to complete the development of, or the period in which material net cash inflows are expected 
to commence from any product candidate, due to the numerous risks and uncertainties associated with developing drugs, including the 
uncertainty of: 

•  Our ability to advance product candidates into pre-clinical and clinical trials. 

•  The scope, rate and progress of our pre-clinical trials and other research and development activities. 

•  The scope, rate of progress and cost of any clinical trials we commence. 

•  The cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights. 

•  Future clinical trial results.  

•  The terms and timing of any collaborative, licensing and other arrangements that we may establish. 

•  The cost and timing of regulatory approvals.  

•  The cost and timing of establishing sales, marketing and distribution capabilities. 

•  The cost of establishing clinical and commercial supplies of our product candidates and any products that we may develop. 

•  The effect of competing technological and market developments.  

Any failure to complete any stage of the development of our products in a timely manner could have a material adverse effect on 
our operations, financial position and liquidity. A discussion of the risks and uncertainties associated with completing our projects on 
schedule, or at all, and the potential consequences of failing to do so, are set forth in the “Risk Factors” section of this Annual Report. 

Critical Accounting Policies and Estimates 

Management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial 
statements,  which  have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States.  The 
preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of 
assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, management 
evaluates  its  estimates,  including  those  related  to  revenue  recognition,  bad  debts,  impairment  of  long-lived  assets,  including  finite 
lived intangible assets, accrued liabilities and certain expenses. We base our estimates on historical experience and on various other 
assumptions  that  are  believed  to  be  reasonable  under  the  circumstances,  the  results  of  which  form  the  basis  for  making  judgments 
about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially 
from these estimates under different assumptions or conditions. 

Our significant accounting policies are summarized in Note 2 to our audited financial statements. We believe the following critical 
accounting  policies  affect  our  more  significant  judgments  and  estimates  used  in  the  preparation  of  our  consolidated  financial 
statements: 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Revenue Recognition 

Nonrefundable license fee revenue is recognized when collectibility is reasonably assured, which is generally upon receipt, when 
no continuing involvement on our part is required and payment of the license fee represents the culmination of the earnings process. 
Nonrefundable license fees received subject to future performance by us, or that are credited against future payments due to us are 
deferred and recognized as services are performed and collectibility is reasonably assured, which is generally upon receipt, or upon 
termination of the agreement and all related obligations thereunder, whichever is earlier. Our revenue recognition policy may require 
us in the future to defer significant amounts of revenue. 

Research and Development Expenses 

Research and development expenses consist of costs incurred for direct and overhead-related research expenses and are expensed 
as incurred. Costs to acquire technologies which are utilized in research and development and which have no alternative future use are 
expensed  when  incurred.  Technology  developed  for  use  in  our  products  is  expensed  as  incurred,  until  technological  feasibility  has 
been established. Expenditures, to date, have been classified as research and development expense in the consolidated statements of 
operations and we expect to continue to expense research and development for the foreseeable future. 

Stock-based Compensation 

We grant stock options and warrants for a fixed number of shares to key employees and directors with an exercise price equal to 
the  fair  market  value  of  the  shares  at  the  date  of  grant.  We  account  for  stock  option  grants  and  warrants  in  accordance  with  APB 
Opinion  No.  25,  Accounting  for  Stock  Issued  to  Employees  (APB  25)  and  related  interpretations  and,  accordingly,  recognize  no 
compensation expense for the stock option grants and warrants issued to employees and directors for which the terms are fixed. 

For  stock  option  grants  and  warrants  which  vest  based  on  certain  corporate  performance  criteria,  compensation  expense  is 
recognized  to  the  extent  that  the  market  price  per  share  exceeds  the  exercise  price  on  the  date  such  criteria  are  achieved  or  are 
probable. At each reporting period end, we must estimate the probability of the criteria specified in the stock based awards being met. 
Different assumptions in assessing this probability could result in additional compensation expense being recognized. 

In  October  1995,  the  FASB  issued  Statement  of  Financial  Accounting  Standards  No.  123,  Accounting  for  Stock-based 
Compensation  (SFAS  123),  which  provides  an  alternative  to  APB  25  in  accounting  for  stock-based  compensation  issued  to 
employees. However, we have continued to account for stock-based compensation in accordance with APB 25. See Notes 2 and 14 to 
our audited financial statements. 

We have also granted stock options and warrants to certain consultants and other third parties. Common stock, stock options and 
warrants granted to consultants and other third parties are accounted for in accordance with SFAS 123 and related interpretations and 
are valued at the fair market value of the common stock, options and warrants granted, as of the date of grant or services received, 
whichever is more reliably measurable. Expense is recognized in the period in which a performance commitment exists or the period 
in which the services are received, whichever is earlier. We anticipate that we will continue to rely on the use of consultants and that 
we  will  be  required  to  expense  the  associated  costs.  We  anticipate  continuing  the  use  of  stock  options  to  compensate  employees, 
directors and consultants, and continuing to expense the options in accordance with APB 25. 

Impairment of Long-Lived Assets 

We review long-lived assets, including finite lived intangible assets, for impairment on an annual basis, as of December 31, or on 
an  interim  basis  if  an  event occurs  that  might reduce  the  fair value of such  assets below  their  carrying  values. An impairment loss 
would  be  recognized  based  on  the  difference  between  the  carrying  value  of  the  asset  and  its  estimated  fair  value,  which  would  be 
determined based on either discounted future cash flows or other appropriate fair value methods. 

In 2002, we recorded an impairment charge of $921,000 related to certain equipment and leasehold improvements based on our 
evaluation  of  the  recoverability  of  the  carrying  amount  of  these  assets  in  accordance  with  the  FASB  Statement  of  Financial 
Accounting  Standards  No.  144  —  Accounting  for  the  Impairment  or  Disposal  of  Long-Lived  Assets  (SFAS  144).  This  impairment 
charge represented the total net book value of these assets. See Note 6 to our audited financial statements. 

In  accordance  with  the  provisions  of  Accounting  Principles  Board  Opinion  No.  18,  The  Equity  Method  of  Accounting  for 
Investments  in  Common  Stock  (APB  18),  we  reviewed  the  net  values  on  our  balance  sheet,  as  of  September  30,  2003,  assigned  to 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Investment in Minority — Owned Entity — Acquired Developed Technology resulting from our acquisition of Blizzard Research and 
Development  Company,  or  Blizzard.  Blizzard  was  recorded  as  an  acquired  development-stage  company  and  there  was  an  external 
valuation  used  for  substantiation  of  the  value  of  the  technology  and  the  investment,  which  was  prepared  as  of  the  date  of  the 
announcement of the transaction February 11, 2002. For our annual audit of fiscal 2002, potential impairment was addressed and the 
valuation  was  updated  internally  using  similar  methods  used  for  the  original  investment.  Based  upon  our  analysis  there  was  no 
impairment. Our auditors for that fiscal year concurred. We continued to measure impairment through these methods on a quarterly 
basis and through the second quarter of 2003, we continued to believe that Blizzard’s proprietary technology was commercially viable, 
subject to its ability to obtain significant financing. At that time we believed there was no impairment. APB 18 requires that a loss in 
value of an investment, which is other than a temporary decline, should be recognized as an impairment loss. Through the third quarter 
of  2003,  Blizzard  had  been  unsuccessful  in  its  attempts  to  raise  a  significant  amount  of  financing  necessary  for  it  to  pursue  its 
commercialization strategy for its products and we subsequently decided not to further invest in this entity. We believe that Blizzard 
was unable to obtain substantial third-party financing primarily because (1) the genomics market, which the Blizzard technology was 
targeting,  had  begun  to  decline  in  2003,  (2)  Blizzard  had  not  completed  a  production  unit  of  its  principal  product  for  testing  by 
potential investors, and (3) certain investors were unwilling to invest without a simultaneous infusion of additional capital from us as 
Blizzard’s 40% shareholder, and we were unable to reach satisfactory terms for such financing. Our analysis consisted of a review of 
the  financial  projections  prepared  by  Blizzard,  application  of  a  discounted  cash  flow  valuation  model  of  Blizzard’s  projected  cash 
flows,  and  consideration  of  other  qualitative  factors  such  as  Blizzard’s  termination  of  its  employees,  its  office  lease  and  its 
engagement of its investment banker. Based upon the quantitative and qualitative factors described above, in addition to others, our 
management  determined  that  the  estimated  fair  value  of  our  investment  in  Blizzard  was  $0  and  that  an  impairment  charge  of  $5.9 
million  was  necessary.  In  considering  the  timing  of  the  write-off,  we  looked  to  Blizzard’s  termination  of  its  employees,  lease  and 
investment banker in October 2003 as affirmation of conditions that existed at September 2003, and therefore recorded the write-off in 
the third quarter of 2003. The write-off had no impact upon our cash or working capital position. It is our understanding that, by the 
end of 2003, Blizzard had ceased operations and was in the process of returning its licensed intellectual property to the University of 
Minnesota. 

Estimated Facility Abandonment Accrual 

During  2002,  we  recorded  a  loss  of  $478,000  associated  with  the  closure  of  our  Atlanta  headquarters  and  relocation  to  Los 
Angeles,  subsequent  to  our  merger  with  Global  Genomics.  This  loss  represents  the  total  remaining  lease  obligations  and  estimated 
operating  costs  through  the  remainder  of  the  lease  term,  less  estimated  sublease  income.  This  accrued  charge  was  combined  with 
deferred rent of $85,000 already recorded, so that the total accrual related to the facility abandonment was $563,000 as of December 
31, 2002. As of December 31, 2004, we had a remaining lease closure accrual of $312,000. To the extent that we are able to negotiate 
a termination of the Atlanta lease, our operating costs are different or our estimates related to sublease income are different, the total 
loss ultimately recognized may be different than the amount accrued as of December 31, 2004 and such difference may be material. 

Quarterly Financial Data 

The following table sets forth unaudited statement of operations data for our most recent two completed fiscal years. This quarterly 
information has been derived from our unaudited financial statements and, in the opinion of management, includes all adjustments, 
consisting  only  of  normal  recurring  adjustments,  necessary  for  a  fair  presentation  of  the  information  for  the  periods  covered.  The 
quarterly financial data should be read in conjunction with our financial statements and related notes. The operating results for any 
quarter are not necessarily indicative of the operating results for any future period.

Quarterly and year to date loss per share amounts are computed independently of each other. Therefore, the sum of the per share 

amounts for the quarters may not agree to the per share amounts for the year. 

Liquidity and Capital Resources 

At December 31, 2004, we had cash, cash equivalents and short-term investments of $3.0 million and total assets of $5.0 million 
compared to $11.6 million and $12.3 million, respectively, at December 31, 2003. Working capital totaled $1.2 million at December 
31, 2004, compared to $10.8 million at December 31, 2003. 

To date, we have relied primarily upon selling equity securities and, to a lesser extent, upon payments from our strategic partners 
and licensees to generate funds needed to finance the implementation of our plans of operations. As a result of the $21.3 million equity 
financing that we completed in January 2005, we believe that our cash and short-term investments balances will be sufficient to meet 
our  cash  requirements  into  the  second  quarter  of  2006.  We  nonetheless  will  be  required  to  obtain  significant  additional  funding  in 
order to execute our business plans. We cannot assure that additional funding will be available on favorable terms, if at all. If we fail 
to obtain additional funding when needed, we may not be able to execute our business plan and our business prospects may suffer, 
which could have a material adverse effect on our ability to become profitable. 

Net  cash  used  in  operating  activities  for  the  year  ended  December  31,  2004  was  $12.4  million,  compared  to  net  cash  used  in 
operating activities of $4.3 million in 2003 and $3.5 million in 2002. Revenues earned and received during 2004, 2003 and 2002 were 
$428,000, $94,000 and $1.1 million respectively. These revenues have been insignificant in relation to our ongoing expenses and arise 
from  our  licensing  of  our  Tranzfect  technology,  which  we  no  longer  consider  part  of  our  core  drug  discovery  and  development 
strategy. Future revenues from these licenses are dependent upon the licensee successfully reaching certain development milestones. 
We do not expect any significant revenues from these licensing agreements in 2005. 

Our net loss for the year ended December 31, 2004 was $16.4 million, which includes the write-off of $3.0 million of in-process 
research and development related to the acquisition of assets from Biorex. The $16.4 million loss resulted in net cash used in operating 
activities of $12.4 million. Adjustments to reconcile net loss to net cash used in operating activities for the year ended December 31, 
2004 were primarily $873,000 of common stock, options and warrants issued in lieu of cash for selling, general and administrative 
services. Additionally, we issued $388,000 of common stock, options and warrants in lieu of cash in connection with certain license 
fees and $1.0 million in connection with research and development activities. Our net loss for the year-ended December 31, 2003 was 
$17.8 million, which resulted in net cash used in operating activities of $4.3 million. Adjustments to reconcile net loss to net cash used 
in operating activities for the year ended December 31, 2003 were primarily $6.7 million of losses from a minority-owned entity, $1.5 
million of common stock, options and warrants issued in lieu of cash for selling, general and administrative services, $1.8 million of 
common  stock  issued  in  connection  with  certain  license  agreements  and  $1.1  million  of  common  stock  issued  in  connection  with 
research and development activities. 

In the year ended December 31, 2004, net cash used in investing activities consisted of $962,000 for the purchase of securities to 
be held to maturity and $772,000 for property and equipment, which includes $447,000 related to assets acquired in connection with 
the  molecular  library  assets  of  Biorex.  The  remaining  fixed  assets  acquired  relate  primarily  to  laboratory  equipment  for  CytRx 
Laboratories. We expect capital spending to remain at current levels for fiscal 2005. Net cash provided by investing activities for the 
year ended December 31, 2003 was $1.2 million, compared to net cash used in investing activities of $2.0 million in 2002. The change 
was primarily due to the purchase, in 2002, of held-to-maturity investments, which subsequently matured in 2003, an increase in fixed 
asset purchases in 2003, as compared to 2002 and the absence of acquisition costs in 2003, as compared to 2002. 

Net cash provided by financing activities in the year ended December 31, 2004 was $4.4 million. The cash provided was the result 
of $430,000 received upon the exercise of stock options and warrants and the $4.0 million private equity financing in October 2004. 
Net cash provided by financing activities for the year ended December 31, 2003 was $14.4 million, compared to net cash provided by 
financing activities of $628,000 in 2002. In May and September 2003, we completed private equity financings raising net proceeds of 
$4.9 million and $7.7 million, respectively. For the year ended December 31, 2003, we also received proceeds from the exercise of 
stock  options  and  warrants  totaling  $1.9  million.  Cash  provided  by  financing  activities  in  2002  was  comprised  primarily  of  the 
exercise of stock options and warrants. 

Based  on  our  internal  projections  of  expected  expenses,  we  believe  that  we  will  have  adequate  working  capital  to  allow  us  to 
operate at our currently planned levels into the second quarter of 2006. Our strategic alliance with UMMS may require us to make 
significant expenditures to fund research at UMMS relating to developing therapeutic products based on UMMS’s proprietary gene 

 
 
 
 
 
 
 
 
 
 
silencing technology that has been licensed to us. The aggregate amount of these expenditures was approximately $2.0 million during 
2004, and is expected under certain circumstances to be approximately $2.4 million during 2005. 

We will require additional capital in order to fund ongoing research and development related to the drug candidates acquired from 
Biorex in October 2004. We expect to initiate a Phase II trial for ALS with one of the compounds, arimoclomol, in the second quarter 
of 2005, and estimate that the Phase II trial will require us to expend approximately $5.5 million over a period of twelve to eighteen 
months,  including  milestone  payments  of  $500,000  that  may  become  payable  to  Biorex  under  certain  circumstances.  We  also  may 
require additional working capital in order to fund any product acquisitions that we consummate. 

Potential  strategic  alliance  partners  or  licensees  of  our  technologies  may  be  a  source  of  future  capital.  The  results  of  our 
technology licensing efforts and the actual proceeds of any fund-raising activities will determine our ongoing ability to operate as a 
going  concern.  Our  ability  to  obtain  future  financings  through  joint  ventures,  product  licensing  arrangements,  equity  financings  or 
otherwise is subject to market conditions and our ability to identify parties that are willing and able to enter into such arrangements on 
terms that are satisfactory to us. There can be no assurance that we will be able to obtain future financing from these sources. 

We expect to incur significant losses for the foreseeable future and there can be no assurance that we will become profitable. Even 

if we become profitable, we may not be able to sustain that profitability. 

The above statements regarding our plans and expectations for future financing are forward-looking statements that are subject to a 
number  of  risks  and  uncertainties.  Our  ability  to  obtain  future  financings  through  joint  ventures,  product  licensing  arrangements, 
equity financings or otherwise is subject to market conditions and our ability to identify parties that are willing and able to enter into 
such arrangements on terms that are satisfactory to us. There can be no assurance that we will be able to obtain future financing from 
these sources. Additionally, depending upon the outcome of our fund raising efforts, the accompanying financial information may not 
necessarily be indicative of future operating results or future financial condition. 

Contractual Obligations 

We  have  no  current  commitments  for  capital  expenditures  in  2005;  however,  we  anticipate  incurring  capital  expenditures  in 
connection with the expansion of our subsidiary’s laboratory. We have no committed lines of credit or other committed funding or 
long-term  debt.  As  of  December  31,  2004,  minimum  annual  future  obligations  for  operating  leases,  minimum  annual  future 
obligations  under  various  license  agreements  and  minimum  annual  future  obligations  under  employment  agreements  consist  of  the

We  have  employment  agreements  with  our  executive  officers,  the  terms  of  which  expire  at  various  times  through  July  2006. 
Certain  agreements  provide  for  minimum  salary  levels,  which  are  subject  to  increase  annually  in  the  Compensation  Committee’s 
discretion,  as  well  as  for  minimum  annual  bonuses.  The  reported  commitment  for  employment  agreements  includes,  among  other 
things, a total of $1.0 million of compensation payable to members of our Scientific Advisory Board through 2008, and a total of $1.2 
million of minimum salary and guaranteed bonuses payable to our executives. 

License and Collaboration Agreements 

In  April  2003,  we  acquired  new  technologies  by  entering  into  exclusive  license  arrangements  with  UMMS  covering  potential 
applications of the medical institution’s proprietary RNAi technology in the treatment of specified diseases, including those within the 
areas of obesity, type 2 diabetes ALS, CMV and covering UMMS’s proprietary technology with potential gene therapy applications 
within the area of cancer. In consideration of the licenses, we made cash payments to UMMS totaling $186,000 and issued it a total of 
1,613,258  shares  of  our  common  stock  which  were  valued,  for  financial  statement  purposes,  at  $1.5  million.  In  May  2003,  we 

 
 
 
 
 
 
 
 
 
  
  
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
   
   
 
 
 
 
broadened  our  strategic  alliance  with  UMMS  by  acquiring  an  exclusive  license  from  that  institution  covering  a  proprietary  DNA-
based  HIV  vaccine  technology.  In  consideration  of  this  license,  we  made  cash  payments  to  UMMS  totaling  $18,000  and  issued  it 
215,101  shares  of  our  common  stock  which  were  valued,  for  financial  statement  purposes,  at  $361,000.  In  July  2004,  we  further 
expanded our strategic alliance with UMMS by entering into a collaboration and invention disclosure agreement with UMMS under 
which  UMMS  will  disclose  to  us  certain  new  technologies  developed  at  UMMS  over  the  next  three  years  pertaining  to  RNAi, 
diabetes,  obesity,  neurodegenerative  diseases  (including  ALS)  and  CMV  and  will  give  the  Company  an  option,  upon  making  a 
specified payment, to negotiate an exclusive worldwide license to the disclosed technologies on commercially reasonable terms. As of 
December 31, 2004, we have made cash payments to UMMS totaling $187,500 pursuant to the collaboration agreement with UMMS, 
but have not yet acquired or made any payments to acquire any options under that agreement. 

In May 2004, we licensed from the technology transfer company of the Imperial College of Science, Technology & Medicine, or 
Imperial  College,  the  exclusive  rights  to  intellectual  property  covering  a  drug  screening  method  using  RIP  140,  which  is  a  nuclear 
hormone co-repressor that is believed to regulate fat accumulation. In consideration of the license, we made cash payments to Imperial 
College  totaling  $87,000  and  issued  it  a  total  of  75,000  shares  of  our  common  stock  which  were  valued,  for  financial  statement 
purposes,  at  $108,000.  As  the  drug  screening  technology  from  Imperial  College  and  the  RNAi  technology  from  UMMS  had  not 
achieved technological feasibility at the time of their license by us, had no alternative future uses and, therefore, no separate economic 
value,  the  total  value  of  all  cash  payments  and  stock  issued  for  acquisition  of  the  technology  was  expensed  as  research  and 
development in our financial statements. 

Net Operating Loss Carryforward 

At December 31, 2004, we had consolidated net operating loss carryforwards for income tax purposes of $73.7 million, which will 
expire in 2005 through 2024 if not utilized. We also have research and development tax credits and orphan drug tax credits available 
to reduce income taxes, if any, of $6.3 million, which will expire in 2005 through 2020 if not utilized. The amount of net operating 
loss  carryforwards  and  research  tax  credits  available  to  reduce  income  taxes  in  any  particular  year  may  be  limited  in  certain 
circumstances. Based on an assessment of all available evidence including, but not limited to, our limited operating history in our core 
business and lack of profitability, uncertainties of the commercial viability of our technology, the impact of government regulation and 
healthcare reform initiatives, and other risks normally associated with biotechnology companies, we have concluded that it is  more 
likely  than  not  that  these  net  operating  loss  carryforwards  and  credits  will  not  be  realized  and,  as  a  result,  a  100%  deferred  tax 
valuation allowance has been recorded against these assets. 

Results of Operations 

CytRx  Corporation  earned  revenues  of  $428,000,  $94,000  and  $1.1  million  during  the  years  ended  2004,  2003  and  2002, 
respectively, primarily from our licensing agreements related to our Tranzfect technology. All future licensing fees under our current 
agreements  are  dependent  upon  successful  development  milestones  being  achieved  by  the  licensor.  In  2005,  we  do  not  anticipate 
receiving any significant licensing fees. 

In 2002, we received a $46,000 grant from the Small Business Innovation Research (SBIR) program for domestic small business 
concerns to engage in research and development related to of our Flocor technology. There were no grant revenues in 2004 or 2003, 
and we do not currently expect to receive SBIR or other similar grants that would provide us funding in 2005.

Research  expenses  are  expenses  incurred  by  us  in  the  discovery  of  new  information  that  will  assist  us  in  the  creation  and  the 
development  of  new  drugs  or  treatments.  Development  expenses  are  expenses  incurred  by  us  in  our  efforts  to  commercialize  the 
findings generated through our research efforts. Our research and development expenses were $9.0 million in 2004, $4.4 million in 
2003 and $800,000 in 2002.

Research and development expenses during 2004 were primarily the result of efforts to develop RNAi through new and existing 
licensing  agreements,  sponsored  research  agreements,  as  well  as  research  and  development  efforts  performed  at  our  obesity  and 
diabetes  subsidiary.  Our  subsidiary  is  working  to  develop  small  molecule  inhibitors  against  proprietary  protein  targets  identified 
through sponsored research agreements and licensing of intellectual property. Research and development expenses incurred in 2003 
were  primarily  for  the  acquisition  and  licensing  of  intellectual  property  and  the  commencement  of  operations  of  our  subsidiary’s 
operations. Research and development expenses in 2002 were primarily related to our Flocor technology, which was subsequently out-
licensed as the technology no longer fit our strategic direction. Also, included in research and development expenses in 2002 was a 
small amount of in-process research and development expense related to a former subsidiary. 

In October 2004, we acquired all of the clinical and pharmaceutical and related intellectual property assets of Biorex, a Hungry-
based company focused on the development of novel small molecules with broad therapeutic applications in neurology, diabetes and 
cardiology for approximately $3.5 million in cash. Included in the assets acquired from Biorex are a 500-compound molecular library, 
as  well  as  the  molecules  arimoclomol,  iroxanadine  and  bimoclomol,  each  of  which  had,  at  the  time  of  acquisition,  successfully 
completed  the  European  equivalent  of  a  Phase  I  clinical  trial.  After  management’s  evaluation  of  the  acquired  technology, 
approximately $3.0 million was written-off as in-process research and development. 

In 2005, we expect our research and development expenses to increase primarily as a result of our expected initiation of a Phase II 
clinical trial with arimoclomol for the treatment of ALS in the second quarter of 2005. We estimate that the Phase II trial will cost 
approximately $5.5 million and will last between 12 and 18 months. Additionally, we estimate that our costs related to the activities of 
our subsidiary to increase by approximately $1.0 million in 2005 as the subsidiary expands its research activities.

General  and  administrative  expenses  include  all  administrative  salaries  and  general  corporation  expenses.  Our  general  and 
administrative  expenses  were  $7.9  million  in  2004,  $7.0  million  in  2003  and  $1.9  million  in  2002.  The  increase  in  general  and 
administrative expenses during 2004 as compared to 2003 is primarily the result of increased audit fees due to our change in auditors, 
severance  paid  to  certain  members  of  management  in  the  first  half  of  2004,  the  hiring  of  additional  executive  officers  and  the 
settlement of certain legal proceedings, for which there was no comparable expenses in 2003. The increase in general administrative 
expenses during 2003 as compared to 2002 is due primarily to our change in our business strategy, which led to an increase in activity 
and, as a result, a greater use of consultants for financial and business development advisory services. 

From time to time, we issue shares of our common stock or warrants to purchase shares or our common stock to consultants and 
other  service  providers  in  exchange  for  services.  For  financial  statement  purposes,  we  value  these  shares  of  common  stock,  stock 
options, and warrants at the fair value of the common stock, stock options or warrants granted, or the services received, whichever is 
more  reliably  measurable.  We  recorded  non-cash  charges  of  $2.0  million,  $3.1  million  and  $200,000  during  2004,  2003  and  2002, 
respectively. These charges relate primarily to common stock, stock options and warrants issued in connection with the engagement 
and retention of financial, business development and scientific advisors. The significant increase in 2003 as compared to 2002 was due 
primarily to the change in our business strategy, which led to greater activity and, as a result, a greater use of consultants, primarily for 
financial and business development services. During 2004, as our business strategy progressed, less use of financial business advisors 
was required, which resulted in substantially fewer options and common stock being issued as compared to 2003. 

Depreciation and amortization expense — Depreciation and amortization expense was $104,000, $2,000 and $794,000 in 2004, 
2003 and 2002 respectively. During the fourth quarter of 2003 and the first two quarters of 2004, we increased our capital spending as 
part of its overall strategy to establish a laboratory subsidiary. During 2004 capital assets increased by $668,000 to $895,000, net of 
depreciation.  As  a  result  of  these  additions  to  assets,  depreciation  related  to  capital  equipment  increased  from  $2,000  in  2003  to 
$104,000  in  2004.  The  $792,000  decrease  in  depreciation  in  2003  as  compared  to  2002  was  the  result  of  an  impairment  charge 
(discussed below) taken in the fourth quarter of 2002. We anticipate our need for additional capital equipment will be modest in the 
future. 

 
 
 
 
 
 
  
 
 
  
 
 
 
 
 
 
 
 
 
Severance and other contractual payments to officers 

In  accordance  with  a  Mutual  General  Release  and  Severance  Agreement  in  May  2004,  we  agreed  to  pay  our  former  General 
Counsel, approximately $87,500 and 12 months of related benefits, and agreed to immediately vest options to purchase 87,500 shares 
of our common stock that were granted upon the commencement of his employment. In accordance with a Mutual General Release 
and Severance Agreement in May 2004, we agreed to pay our former Chief Financial Officer, approximately $150,000 and 18 months 
of related benefits, and agreed to immediately vest options to purchase 105,000 shares of our common stock that were granted upon 
the commencement of his employment. 

Pursuant to his employment agreement, our former President and CEO, Jack Luchese, was entitled to a payment of $435,000 upon 
the execution of the merger agreement between Global Genomics and us and an additional $435,000 upon the closing of the merger. 
In order to reduce the amount of cash that we had to pay to Mr. Luchese, Mr. Luchese and we agreed that approximately $325,200 of 
the first $435,000 payment would be satisfied by CytRx granting a stock award to Mr. Luchese under our 2000 Long-Term Incentive 
Plan pursuant to which we issued Mr. Luchese 558,060 shares of our common stock. Those shares of stock were issued at a value 
equal to 85% of the volume weighted average price of our common stock for the 20 trading days ended on February 8, 2002. The cash 
payment and fair value of the shares issued were recognized as expense (total of $428,000) during the first quarter of 2002. 

The terms of our merger with Global Genomics contemplated that their management team would replace ours subsequent to the 
closing of the merger. On July 16, 2002, we terminated the employment of all of our then current officers, resulting in total obligations 
for severance, stay bonuses, accrued vacation and other contractual payments of $1.4 million (including the final $435,000 owed to 
Mr. Luchese as discussed above). Prior to the merger closing date, we advanced part of these amounts to three of our officers (through 
salary continuance), such that the total remaining obligation at the closing date was $1.2 million. Four of our officers agreed to accept 
an aggregate total of $177,000 of this amount in the form of our common stock in lieu of cash, resulting in the issuance of 248,799 
shares. Thus, the net cash payout in satisfaction of these obligations was $1.0 million, before taxes. The severance payments and fair 
value of the shares issued (total expense of $1.4 million) was recognized as expense during the third quarter of 2002 and is reported as 
a  separate  line  item  on  the  accompanying  consolidated  statement  of  operations,  together  with  the  final  payment  to  Mr.  Luchese 
discussed above. 

Asset  impairment  charge  —  During  the  fourth  quarter  of  2002,  we  recognized  an  asset  impairment  charge  of  approximately 
$921,000  related  to  our  equipment  and  facility  used  for  Flocor  production.  We  recorded  an  impairment  loss  equal  to  the  net  book 
value of the equipment and related leasehold improvements. 

Loss on facility abandonment — During the fourth quarter of 2002, we recognized a loss of $478,000 associated with the closure 
of our Atlanta headquarters and relocation to Los Angeles subsequent to our merger with Global Genomics. This loss represents the 
difference  between  the  total  remaining  lease  obligations  and  estimated  operating  costs  through  the  remainder  of  the  lease,  which 
expires in 2008, less estimated sublease income. 

Interest  income  —  Interest  income  was  $60,000  in  2004,  as  compared  to  $82,000  in  2003  and  $96,000  in  2002.  The  variances 

between years are primarily attributable to the cash available for investment.

Blizzard ceased operations at the end of 2003. Prior to that time, we recorded our portion of the net loss of Blizzard in accordance 
with  the  equity  method  of  accounting.  In  2003,  we  recorded  $6.7  million  in  equity  losses,  of  which  $5.9  million  was  an  asset 
impairment  charge,  $245,000  was our 40% share  of  the net  loss  in  Blizzard  and $548,000 was  amortization  of  acquired  developed 
technology. For the period July 19, 2002 (date of acquisition of Global) to December 31, 2002, we recorded $665,000 in equity losses, 
of  which  $330,000  was  our  share  in  the  net  losses  of  Blizzard  Genomics  and  $335,000  was  amortization  of  acquired  developed 
technology. 

 
 
 
 
 
 
 
 
 
 
  
 
 
  
 
 
 
 
 
 
 
 
Minority interest in losses of subsidiary — We recorded $160,000 in 2004 and $20,000 in 2003 related to the 5% minority interest 

in losses of CytRx Laboratories, which we acquired in September 2003. 

Recently Issued Accounting Standards 

On  December  16,  2004,  the  Financial  Accounting  Standards  Board  (FASB)  issued  FASB  Statement  No.  123  (revised  2004), 
“Share-Based  Payment,”  or  SFAS  123(R),  which  is  a  revision  of  FASB  Statement  No.  123,  “Accounting  for  Stock-Based 
Compensation.”  SFAS  123(R)  supersedes  APB  Opinion  No.  25,  “Accounting  for  Stock  Issued  to  Employees,”  and  amends  FASB 
Statement  No.  95,  “Statement  of  Cash  Flows.”  Generally,  the  approach  in  SFAS  123(R)  is  similar  to  the  approach  described  in 
Statement 123. However, SFAS 123(R) requires all share-based payments to employees, including grants of employee stock options, 
to be recognized in the statement of operations based on their fair values. Pro forma disclosure is no longer an alternative. 

SFAS 123(R) must be adopted by us for interim periods beginning after July 1, 2005. Early adoption will be permitted in periods 
in  which  financial  statements  have  not  yet  been  issued.  We  expect  to  adopt  SFAS  123(R)  on  July  1,  2005.  SFAS  123(R)  permits 
companies to adopt its requirements using one of two methods. 

The  first  method  is  a  modified  prospective  transition  method  whereby  a  company  would  recognize  share-based  employee  costs 
from  the  beginning  of  the  fiscal  period  in  which  the  recognition  provisions  are  first  applied  as  if  the  fair  value-based  accounting 
method had been used to account for all employee awards granted, modified, or settled after the effective date and to any awards that 
were not fully vested as of the effective date. Measurement and attribution of compensation cost for awards that are nonvested as of 
the effective date of SFAS 123(R) would be based on the same estimate of the grant-date fair value and the same attribution method 
used previously under SFAS 123. 

The  second  adoption  method  is  a  modified  retrospective  transition  method  whereby  a  company  would  recognize  employee 
compensation cost for periods presented prior to the adoption of SFAS 123(R) in accordance with the original provisions of SFAS 
123, that is, an entity would recognize employee compensation cost in the amounts reported in the pro forma disclosures provided in 
accordance  with  SFAS  123.  A  company  would  not  be  permitted  to  make  any  changes  to  those  amounts  upon  adoption  of  SFAS 
123(R) unless those changes represent a correction of an error. For periods after the date of adoption of SFAS 123(R), the modified 
prospective transition method described above would be applied. 

We currently expect to adopt SFAS 123(R) using the modified prospective transition method, and expect the adoption to have an 
effect on our results of operations similar to the amounts reported historically in our footnotes (see Note 14 to our audited financial 
statements) under the pro forma disclosure provisions of SFAS 123. 

Related Party Transactions 

Dr.  Michael  Czech,  a  5%  shareholder  of  our subsidiary  (see  Note  19  to  our  audited  financial  statements)  and  a  member  of  our 
subsidiary’s Scientific Advisory Boards, is an employee of UMMS and party, as the principal investigator, to a sponsored research 
agreement between UMMS and us. As of December 31, 2004, we recorded a minority interest liability of $350,000 representing the 
5% interest in our subsidiary held by Dr. Czech. Additionally, we have recorded the fair value of 300,000 shares of our common stock 
as additional paid-in capital for our right to call and the Dr. Czech’s right to put the remaining 5% interest to us in exchange for a 
guaranteed amount of 300,000 shares of our common stock. The fair value of these shares on the purchase date was approximately 
$723,000. During 2004 and 2003, Dr. Czech was paid $171,000 and $18,000, respectively, for his Scientific Advisory Board services. 
During  each  of  2004  and  2003,  we  paid  UMMS  $403,000  under  a  sponsored  research  agreement  to  fund  a  portion  of  Dr.  Czech’s 
research. 

Off-Balance Sheet Arrangements 

We have not entered into off-balance sheet financing arrangements, other than operating leases. 

 
 
 
 
 
 
 
 
 
 
 
 
 
RISK FACTORS 

If any of the following risks actually occur, our business or prospects could be materially adversely affected. You should also refer 

to the other information in this Annual Report, including our financial statements and the related notes. 

We Have Operated at a Loss and Will Likely Continue to Operate at a Loss For the Foreseeable Future 

We have incurred significant losses over the past five years, including net losses of $16.4 million, $17.8 million and $6.2 million 
for  the  years  ended  December  31,  2004, 2003 and 2002,  respectively,  and  we  had  an  accumulated  deficit  of  approximately  $106.2 
million as of December 31, 2004. Our operating losses have been due primarily to our expenditures for research and development on 
our  products  and  for  general  and  administrative  expenses  and  our  lack  of  significant  revenues.  We  are  likely  to  continue  to  incur 
operating losses until such time, if ever, that we generate significant recurring revenues. Unless we are able to acquire products from 
third parties that are already being marketed and that can be profitably marketed by us, we anticipate it will take a minimum of three 
years  (and  possibly  longer)  for  us  to  generate  recurring  revenues,  since  we  expect  that  it  will  take  at  least  that  long  before  the 
development of any of our licensed or other current potential products is completed, marketing approvals are obtained from the United 
States Food and Drug Administration, or FDA, and commercial sales of any of these products can begin. 

We Have No Source of Significant Recurring Revenues, Which Makes Us Dependent on Financing to Sustain Our Operations 

Our revenues were $428,000, $94,000 and $1.1 million during the years ended December 31, 2004, 2003 and 2002, respectively. 

We will not have significant recurring operating revenues until at least one of the following occurs: 

•  We are able to complete the development of and commercialize one or more of the products that we are currently developing, 

which may require us to first enter into license or other arrangements with third parties. 

•  One or more of our currently licensed products is commercialized by our licensees, thereby generating royalty income for us. 

•  We are able to acquire products from third parties that are already being marketed or are approved for marketing. 

We  are  likely  to  incur  negative  cash  flow  from  operations  until  such  time,  if  ever,  as  we  can  generate  significant  recurring 
revenues.  On  January  26,  2005,  we  completed  a  private  placement  financing  and  received  net  proceeds  of  approximately  $19.5 
million. Although we believe that we have adequate financial resources to support our currently planned level of operations into the 
second  quarter  of  2006,  it  is  likely  that  we  will  be  dependent  on  obtaining  financing  from  third  parties  to  continue  to  meet  our 
obligations  to  UMMS,  and  maintain  our  operations,  including  our  planned  levels  of  operations  for  our  obesity  and  type  2  diabetes 
subsidiary  and  our  ongoing  research  and  development  efforts  related  to  the  drug  candidates  acquired  from  Biorex.  We  have  no 
commitments  from  third  parties  to  provide  us  with  any  additional  debt  or  equity  financing.  Accordingly,  future  financing  may  be 
unavailable to us or only available on terms that substantially dilute our existing stockholders. A lack of needed financing could force 
us to reduce the scope of, or terminate, our operations, or to seek a merger with or be acquired by another company. There can be no 
assurance that we would be able to identify an appropriate company to merge with or be acquired by or that we could consummate 
such a transaction on terms that would be attractive to our stockholders or at all. 

Most  of  Our  Revenues  Have  Been  Generated  by  License  Fees  for  TranzFect,  Which  May  Not  be  a  Recurring  Source  of 
Revenue for Us 

License fees paid to us with respect to our TranzFect technology have represented 93%, 81% and 94% of our total revenues for the 
years  ended December 31, 2004,  2003  and  2002,  respectively. We have  already  licensed  most  of  the  potential  applications for  this 
technology, and there can be no assurance that we will be able to generate additional license fee revenues from any new licensees for 
this technology. Our current licensees for TranzFect, Merck, and Vical,  may be required to make further milestone payments to us 
under their licenses based on their future development of products using TranzFect. However, Vical has only recently commenced two 
Phase I clinical trials of products utilizing TranzFect as a component of a vaccine to prevent CMV. Since TranzFect is to be used as a 
component in vaccines, we do not need to seek FDA approval, but any vaccine manufacturer will need to seek FDA approval for the 
final vaccine formulation containing TranzFect. Merck has completed a multi-center, blinded, placebo controlled Phase I trial of an 
HIV vaccine utilizing TranzFect as a component. In the Merck trials, although the formulation of the tested vaccine using TranzFect 
was generally safe, well-tolerated and generated an immune response, the addition of TranzFect to the vaccine did not increase this 
immune  response.  Moreover,  the  DNA  single-modality  vaccine  regimen  with  TranzFect,  when  tested  in  humans,  yielded  immune 
responses  that  were  inferior  to  those  obtained  with  the  DNA  vaccines  in  macaque  monkeys.  Accordingly,  there  is  likely  to  be  a 

 
 
 
 
 
 
 
 
 
 
 
 
 
substantial  period  of  time,  if  ever,  before  we  receive  any  further  significant  payments  from  Merck  or  Vical  under  their  TranzFect 
licenses. 

We Have Changed Our Business Strategy, Which Will Require Us, in Certain Cases, to Find and Rely Upon Third Parties for 
the Development of Our Products and to Provide Us With Products 

Following  our  merger  with  Global  Genomics,  we  modified  our  business  strategy  of  internally  developing  Flocor  and  the  other, 
then-current, potential products that we had not yet licensed to third parties. Instead, we began to seek to enter into strategic alliances, 
license agreements or other collaborative arrangements with other pharmaceutical companies that would provide for those companies 
to  be  responsible  for  the  development  and  marketing  of  those  products.  In  June  2004,  we  licensed  Flocor,  the  primary  potential 
product that we held prior to the Global Genomics merger and which we had not already licensed to a third party, to SynthRx, Inc., a 
recently formed Houston, Texas-based biopharmaceutical company, under a strategic alliance that we entered into with that company 
in October 2003. Although we intend to internally fund or carry out a significant portion of the research and development related to at 
least  one  of  the  drug  candidates  that  we  acquired  from  Biorex,  and,  through  our  subsidiary,  the  early  stage  development  work  for 
certain product applications based on the RNAi and other technologies that we licensed from UMMS, and we may seek to fund all of 
the later stage development work for our potential ALS products, the completion of the development, manufacture and marketing of 
these  products  is  likely  to  require,  in  many  cases,  that  we  enter  into  strategic  alliances,  license  agreements  or  other  collaborative 
arrangements with larger pharmaceutical companies for this purpose. 

There  can  be  no  assurance  that  our  products  will  have  sufficient  potential  commercial  value  to  enable  us  to  secure  strategic 
alliances, license agreements or other collaborative arrangements with suitable companies on attractive terms or at all. If we are unable 
to  enter  into  collaborative  agreements,  we  may  not  have  the  financial  or  other  resources  to  continue  development  of  a  particular 
product or the development of any of our products. In connection with the Phase I clinical trial currently being conducted by UMMS 
and  ABL  on  an  HIV  vaccine  candidate  that  utilizes  a  technology  that  we  licensed  from  UMMS,  we  do  not  have  a  commercial 
relationship with the company that provided an adjuvant for the vaccine for the trial. If we are not able to enter into an agreement with 
this company on terms favorable to us or at all, we may be unable to use some or all of the results of the clinical trial as part of our 
clinical data for obtaining FDA approval of this vaccine, which will delay the development of the vaccine. 

If we enter into these collaborative arrangements, we will be dependent upon the timeliness and effectiveness of the development 
and marketing efforts of our contractual partners. If these companies do not allocate sufficient personnel and resources to these efforts 
or encounter difficulties in complying with applicable regulatory (including FDA) requirements, the timing of receipt or amount of 
revenues  from  these  arrangements  may  be  materially  and  adversely  affected.  By  entering  into  these  arrangements  rather  than 
completing  the  development  and  then  marketing  these  products  on  our  own,  we  may  suffer  a  reduction  in  the  ultimate  overall 
profitability for us of these products. In addition, if we are unable to enter into these arrangements for a particular product, we may be 
required to either sell our rights in the product to a third party or abandon it unless we are able to raise sufficient capital to fund the 
substantial expenditures necessary for development and marketing of the product. 

We will also seek to acquire products from third parties that already are being marketed or have previously been marketed. We 
have not yet identified any of these products. Even if we do identify such products, it may be difficult for us to acquire them with our 
limited financial resources and, if we acquire products using our securities as currency, we may incur substantial shareholder dilution. 
We do not have any prior experience in acquiring or marketing products and may need to find third parties to market these products 
for  us.  We  may  also  seek  to  acquire  products  through  a  merger  with  one  or  more  companies  that  own  such  products.  In  any  such 
merger, the owners of our merger partner could be issued or hold a substantial, or even controlling, amount of stock in our company 
or, in the event that the other company is the surviving company, in that other company. 

Our Current Financial Resources May Limit Our Ability to Execute Certain Strategic Initiatives 

In June 2004, we licensed Flocor to SynthRx, which will be responsible for developing potential product applications for Flocor. 
Although  we  are  not  doing  any  further  development  work  on  TranzFect  or  Flocor,  should  our  three  principal  licensees  for  those 
technologies successfully meet the defined milestones, we could receive future milestone payments and, should any of the licensees 
commercialize products based upon our technology, future royalty payments. However, there can be no assurance that our licensees 
will continue to develop or ever commercialize any products that are based on our Flocor or our TranzFect technology. 

Our strategic alliance with UMMS will require us to make significant expenditures to fund research at the institution relating to the 
development  of  therapeutic  products  based  on  the  UMMS  proprietary  technologies  that  we  have  licensed  and  pursuant  to  our 
collaboration and invention disclosure agreement with UMMS. We estimate that the aggregate amount of these expenditures under our 

 
 
 
 
 
 
 
 
 
 
current commitments will be $2.4 million for 2005, approximately $1.5 million for 2006 and approximately $310,000 for 2007. We 
have also agreed to fund approximately $209,000 of sponsored research at Massachusetts General Hospital during 2005 and 2006. Our 
license agreements with UMMS also provide, in certain cases, for milestone payments based on the progress we make in the clinical 
development and marketing of products utilizing the licensed technologies. In the event that we were to successfully develop a product 
in  each  of  the  categories  of  obesity/type  2  diabetes,  ALS,  CMV,  cancer  and  an  HIV  vaccine,  under  our  licenses,  those  milestone 
payments  could  aggregate  up  to  $16.1  million.  In  addition,  the  agreement  pursuant  to  which  we  acquired  the  clinical  and 
pharmaceutical assets of Biorex provides for milestone payments based on the occurrence of certain regulatory filings and approvals 
related  to  the  acquired  products.  In  the  event  that  we  were  to  successfully  develop  any  of  those  products,  the  milestone  payments 
could  aggregate  up  to  $4.2  million.  Each  of  the  foregoing  milestone  payments,  however,  could  vary  significantly  based  upon  the 
milestones we achieve and the number of products we ultimately undertake to develop. 

Although we believe that an existing grant from the National Institute of Health, or NIH, will be sufficient to fund substantially all 
of the costs of an ongoing Phase I trial of the HIV vaccine candidate using the technology we licensed from UMMS and Advanced 
BioScience Laboratories, or ABL, we could be required to fund substantial expenses of the trial not covered by the grant. Under our 
license  for  this  technology,  following  the  completion  of  the  current  Phase  I  trial,  we  will  be  responsible  for  all  of  the  costs  for 
subsequent clinical trials for this vaccine. The costs of subsequent trials for the HIV vaccine will be very substantial. We do not have 
any  NIH  or  other  governmental  funding  for  these  future  trials,  and  there  can  be  no  assurance  that  we  will  be  able  to  secure  such 
funding for any of these trials. 

The  expenditures  potentially  required  under  our  agreements  with  UMMS  and  ABL,  together  with  the  operating  capital 
requirements  of  our  obesity  and  type  2  diabetes  subsidiary,  our  planned  sponsored  research  funding  for  Massachusetts  General 
Hospital  and  our  development  of  the  drug  candidates  acquired  from  Biorex,  substantially  exceed  our  current  financial  resources. 
Although  we  raised  approximately  $19.5  million  in  January  2005,  net  of  transaction  expenses,  those  required  expenditures  will 
nonetheless require us to raise additional capital or to secure a licensee or strategic partner to fulfill our obligations to UMMS and to 
develop any products based on the technologies that we have licensed from UMMS or any products that we acquired from Biorex, and 
to  continue  the  operations  of  our  subsidiary  at  the  currently  contemplated  level.  If  we  are  unable  to  meet  our  various  financial 
obligations  under  license  agreements  with  UMMS,  we  could  lose  all  of  our  rights  under  those  agreements.  If  we  were  to  have 
inadequate financial resources at that time, we also could be forced to reduce the level of, or discontinue, operations at our subsidiary. 

If Our Products Are Not Successfully Developed and Approved by the FDA, We May Be Forced to Reduce or Terminate Our 
Operations 

All  of  our  products  are  at  various  stages  of  development  and  must  be  approved  by  the  FDA  or  similar  foreign  governmental 
agencies before they can be marketed. The process for obtaining FDA approval is both time-consuming and costly, with no certainty 
of  a  successful  outcome.  This  process  typically  includes  the  conduct  of  extensive  pre-clinical  and  clinical  testing,  which  may  take 
longer or cost more than we or our licensees anticipate, and may prove unsuccessful due to numerous factors. Product candidates that 
may appear to be promising at early stages of development may not successfully reach the market for a number of reasons. The results 
of preclinical and initial clinical testing of these products may not necessarily indicate the results that will be obtained from later or 
more extensive testing. Companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced 
clinical trials, even after obtaining promising results in earlier trials. 

Numerous factors could affect the timing, cost or outcome of our drug development efforts, including the following: 

•  Difficulty in securing centers to conduct trials.  

•  Difficulty in enrolling patients in conformity with required protocols or projected timelines. 

•  Unexpected adverse reactions by patients in trials.  

•  Difficulty in obtaining clinical supplies of the product.  

•  Changes in the FDA’s requirements for our testing during the course of that testing. 

• 

Inability to generate statistically significant data confirming the efficacy of the product being tested. 

•  Modification of the drug during testing.  

 
 
 
 
 
 
 
 
 
 
 
 
 
 
•  Reallocation of our limited financial and other resources to other clinical programs. 

It is possible that none of the products we develop will obtain the appropriate regulatory approvals necessary for us to begin selling 
them. The time required to obtain FDA and other approvals is unpredictable but often can take years following the commencement of 
clinical trials, depending upon the complexity of the drug candidate. Any analysis we perform of data from clinical activities is subject 
to  confirmation  and  interpretation  by  regulatory  authorities,  which  could  delay,  limit  or  prevent  regulatory  approval.  Any  delay  or 
failure in obtaining required approvals could have a material adverse effect on our ability to generate revenues from the particular drug 
candidate and we may not have the financial resources to continue to develop our products and may have to terminate our operations. 

The Approach We Are Taking to Discover and Develop Novel Drugs Using RNAi and Other Technologies is Unproven and 
May Never Lead to Marketable Products 

The RNAi and other technologies that we have acquired from UMMS have not yet been clinically tested by us, nor are we aware 
of any clinical trials having been completed by third parties involving similar technologies. Neither we nor any other company has 
received  regulatory  approval  to  market  therapeutics  utilizing  RNAi.  The  scientific  discoveries  that  form  the  basis  for  our  efforts  to 
discover and develop new drugs are relatively new. The scientific evidence to support the feasibility of developing drugs based on 
these discoveries is both preliminary and limited. Successful development of RNAi-based products will require solving a number of 
issues,  including  providing  suitable  methods  of  stabilizing  the  RNAi  drug  material  and  delivering  it  into  target  cells  in  the  human 
body. We may spend large amounts of money trying to solve these issues, and never succeed in doing so. In addition, any compounds 
that we develop may not demonstrate in patients the chemical and pharmacological properties ascribed to them in laboratory studies, 
and they may interact with human biological systems in unforeseen, ineffective or harmful ways. 

The Drug Candidates Acquired from Biorex May Not Obtain Regulatory Marketing Approvals 

On October 4, 2004, we acquired all of the clinical and pharmaceutical assets and related intellectual property of Biorex, including 
three drug candidates (arimoclomol, iroxanadine and bimoclomol), and a library of small molecule drug candidates. Although each of 
arimoclomol, iroxanadine and bimoclomol has undergone clinical testing, significant and costly additional testing will be required in 
order to bring any product to market. We may be unable to confirm in our pre-clinical or clinical trials with arimoclomol, iroxanadine 
or  bimoclomol  the  favorable  pre-clinical  or  clinical  data  previously  generated  by  European  investigators  for  these  drug  candidates, 
which could require us to have to modify our development plans for these compounds. 

We  expect  to  initiate  Phase  II  clinical  testing  for  arimoclomol  for  ALS  in  the  second  quarter  of  2005,  however  there  are  no 
assurances that the clinical testing will be successful. We believe that the FDA may accept the completion of a successful Phase II 
clinical trial as sufficient to enable us to submit a New Drug Application, or NDA, however there are no guarantees that the FDA will 
accept our Phase II study in lieu of a Phase III clinical trial. If the FDA requires us to complete a Phase III clinical trial, the cost of 
development of arimoclomol will increase beyond our estimated costs. In addition, the FDA ultimately could require us to achieve an 
efficacy end point in the clinical trials for arimoclomol that could be more difficult, expensive and time-consuming than our planned 
end point. Although we anticipate developing arimoclomol for the treatment of ALS, arimoclomol has also shown therapeutic efficacy 
in  a  preclinical  animal  model  of  diabetes  and we  may  pursue development  of  arimoclomol  for  diabetic  indications.  However,  such 
development would require significant and costly additional testing. There is no guarantee that arimoclomol would show any efficacy 
for any other indications. 

Iroxanadine has been tested in two Phase I clinical trials and one Phase II clinical trial which showed improvement in the function 
of  endothelial  cells  in  blood  vessels  of  patients  at  risk  of  cardiovascular  disease.  We  intend  to  develop  this  product  to  improve 
endothelial  dysfunction  in  indications  such  as  diabetic  retinopathy  and  wound  healing,  which  will  require  significant  and  costly 
additional testing. There is no guarantee that iroxanadine will show any efficacy in the intended uses we are seeking. We may also 
attempt to license iroxanadine to larger pharmaceutical or biotechnology companies for cardiovascular indications; however, there is 
no guarantee that any such company will be interested in licensing iroxanadine from us or on terms that are favorable to us. 

Bimoclomol has been tested in two Phase II clinical trials where it was shown to be safe, but where it did not show efficacy for 
diabetic  neuropathy,  the  indication  for  which  it  was  tested.  We  intend  to  develop  this  compound  for  other  therapeutic  indications, 
however there can be no guarantee that this compound will be effective in treating any diseases. In addition, the FDA may require us 
to perform new safety clinical trials, which would be expensive and time consuming and would delay development of bimoclomol. 
There is no guarantee that any additional clinical trials will be successful or that the FDA will approve any of these products and allow 
us to begin selling them in the United States. 

 
 
 
 
 
 
 
 
 
 
 
Our Obesity and Type 2 Diabetes Subsidiary May Not Be Able to Develop Products 

In  order  to  develop  new  obesity  and  type  2  diabetes  products,  our  subsidiary,  CytRx  Laboratories,  will  first  need  to  identify 
appropriate  drug  targets  and  pathways.  We  will  be  using  novel  RNAi-based  techniques  to  accelerate  this  process,  but  there  is  no 
assurance that these techniques will accelerate our work or that we will be able to identify highly promising targets or pathways using 
these  techniques  or  otherwise.  Even  if  we  are  successful  in  identifying  these  targets  or  pathways,  we  will  need  to  then  develop 
proprietary molecules that are safe and effective against these targets. The development process and the clinical testing of our potential 
products will take a lengthy period of time and involve expenditures substantially in excess of our current financial resources that are 
available for this purpose. We currently plan to seek a strategic alliance with a major pharmaceutical or biotechnology company at a 
relatively early stage in our development work to complete the development, clinical testing and manufacturing and marketing of our 
obesity and type 2 diabetes products, but we may not be able to secure such a strategic partner on attractive terms or at all. We do not 
have  prior  experience  in  operating  a  genomic  and  proteomic-based  drug  discovery  company.  Accordingly,  we  will  be  heavily 
dependent on the prior experience and current efforts of Dr. Michael P. Czech, the Chairman of the Scientific Advisory Board of our 
subsidiary, Dr. Jack Barber, our Senior Vice President — Drug Development, and Dr. Mark A. Tepper, the President of our subsidiary 
and a Vice President of CytRx Corporation, in establishing the scientific goals and strategies of our subsidiary. 

We Will Be Reliant Upon SynthRx to Develop and Commercialize Flocor 

In June 2004, we licensed Flocor and our other co-polymer technologies to SynthRx and acquired a 19.9% equity interest in that 
newly  formed  biopharmaceutical  company.  SynthRx  has  only  limited  financial  resources  and  will  have  to  either  raise  significant 
additional  capital  or  secure  a  licensee  or  strategic  partner  to  complete  the  development  and  commercialization  of  Flocor  and  these 
other technologies. We are not aware that SynthRx has any commitments from third parties to provide the capital that it will require, 
and there can be no assurance that it will be able to obtain this capital or a licensee or strategic partner on satisfactory terms or at all. 

Our  prior  Phase  III  clinical  trial  of  Flocor  for  the  treatment  of  sickle  cell  disease  patients  experiencing  an  acute  vaso-occlusive 
crisis did not achieve its primary objective. However, in this study, for patients 15 years of age or younger, the number of patients 
achieving a resolution of crisis was higher for Flocor-treated patients at all time periods than for placebo-treated patients, which may 
indicate that future clinical trials should focus on juvenile patients. Generating sufficient data to seek FDA approval for Flocor will 
require additional clinical studies which have not yet been funded or commenced by SynthRx, and those studies will entail substantial 
time and expense for SynthRx. 

The  manufacture  of  Flocor  involves  obtaining  new  raw  drug  substance  and  a  supply  of  the  purified  drug  from  the  raw  drug 
substance,  which  requires  specialized  equipment.  Should  SynthRx  encounter  difficulty  in  obtaining  the  purified  drug  substance  in 
sufficient amounts and at acceptable prices, SynthRx may be unable to complete the development or commercialization of Flocor on a 
timely basis or at all. 

We Are Unlikely to Recover Any Amounts from Global Genomics’ Portfolio Companies 

Due to its inability to raise needed capital, Blizzard, which was Global Genomics’ principal portfolio company, has been unable to 
complete the development of any of its products and has been notified by the licensor of its core technologies that it is in default under 
its license for those technologies. Global Genomics’ other portfolio company is at a very early stage, is operating without any full-time 
or salaried employees and has not been able to raise the capital it will need to fund its planned operations and to acquire licenses to 
certain  technologies  that  it  will  require.  Accordingly,  it  appears  unlikely  that  either  of  Global  Genomics’  portfolio  companies  will 
generate  revenues  for  us  in  the  future  and,  in  2003,  we  recorded  a  write-off  of  the  carrying  value  of  our  investments  in  those 
companies. 

We May Be Involved in Legal Proceedings That Could Affect Our Business Operations or Financial Condition 

We may be involved, from time to time, in investigations and proceedings by governmental or self-regulatory agencies, certain of 
which  could  result  in  adverse  judgments,  fines  or  other  sanctions.  In  February  2004,  we  were  notified  by  the  Massachusetts  State 
Ethics Commission, or the Massachusetts Commission, that it had initiated a preliminary inquiry into whether our previous retention 
of a consultant who introduced us to UMMS constituted an improper conflict of interest under Massachusetts’ ethics laws. UMMS has 
recently advised us that it continues to believe that its agreements with us provided excellent value for UMMS, that it anticipates that 
the Massachusetts Commission’s review of the terms of those agreements will confirm that the agreements were fair to UMMS, and 

 
 
 
 
 
 
 
 
 
 
 
 
that it believes that the Massachusetts Commission will concur with the resolution of the conflict proposed by UMMS under which the 
consultant will forfeit to UMMS certain of the compensation that the consultant was to receive from us. 

We Are Subject to Intense Competition That Could Materially Impact Our Operating Results 

We and our strategic partners or licensees may be unable to compete successfully against our current or future competitors. The 
pharmaceutical,  biopharmaceutical  and  biotechnology  industry  is  characterized  by  intense  competition  and  rapid  and  significant 
technological advancements. Many companies, research institutions and universities are working in a number of areas similar to our 
primary fields of interest to develop new products. There also is intense competition among companies seeking to acquire products 
that  already  are  being  marketed.  Many  of  the  companies  with  which  we  compete  have  or  are  likely  to  have  substantially  greater 
research  and  product  development  capabilities  and  financial,  technical,  scientific,  manufacturing,  marketing,  distribution  and  other 
resources than at least some of our present or future strategic partners or licensees. 

As a result, these competitors may:  

•  Succeed in developing competitive products sooner than us or our strategic partners or licensees. 

•  Obtain FDA and other regulatory approvals for their products before approval of any of our products. 

•  Obtain patents that block or otherwise inhibit the development and commercialization of our product candidates. 

•  Develop products that are safer or more effective than our products. 

•  Devote greater resources to marketing or selling their products. 

• 

• 

Introduce or adapt more quickly to new technologies or scientific advances. 

Introduce products that render our products obsolete.  

•  Withstand price competition more successfully than us or our strategic partners or licensees. 

•  Negotiate third-party strategic alliances or licensing arrangements more effectively. 

•  Take advantage of other opportunities more readily.  

A  number  of  medical  institutions  and  pharmaceutical  companies  are  seeking  to  develop  products  based  on  gene  silencing 
technologies.  Companies  working  in  this  area  include  Sirna  Therapeutics,  Inc.,  Alnylam  Pharmaceuticals,  Inc.,  Benitec  Ltd., 
Nucleonics, Inc. and a number of the multinational pharmaceutical companies. A number of products currently are being marketed by 
a  variety  of  the  multinational  or  other  pharmaceutical  companies  for  treating  type  II  diabetes,  including  among  others  the  diabetes 
drugs Avandia(R) by Glaxo SmithKline PLC, Actos(R) by Eli Lilly & Co., Glucophage(R) by Bristol-Myers Squibb Co., Symlin(R) 
by  Amylin  Pharmaceuticals,  Inc.  and  Starlix(R)  by  Novartis  and  the  obesity  drugs  Xenical(R)  by  F.  Hoffman-La  Roche  Ltd.  and 
Meridia(R)  by  Abbott  Laboratories.  Many  major  pharmaceutical  companies  are  also  seeking  to  develop  new  therapies  for  these 
disease  indications.  Companies  developing  HIV  vaccines  that  could  compete  with  our  HIV  vaccine  technology  include  Merck, 
VaxGen, Inc., Epimmune, Inc., AlphaVax, Inc. and Immunitor Corporation. 

Currently,  Rilutek(R),  which  was  developed  by  Aventis  Pharma  AG,  is  the  only  drug  of  which  we  are  aware  that  has  been 
approved  by  the  FDA  for  the  treatment  of  ALS.  Other  companies  are  working  to  develop  pharmaceuticals  to  treat  ALS,  including 
Aeolus  Pharmaceuticals  and  Oxford  BioMedica  plc.  In  addition,  ALS  belongs  to  a  family  of  diseases  called  neurodegenerative 
diseases,  which  includes  Alzheimer’s,  Parkinson’s  and  Huntington’s  disease.  Due  to  similarities  between  these  diseases,  a  new 
treatment for one ailment potentially could be useful for treating others. There are many companies that are producing and developing 
drugs  used  to  treat  neurodegenerative  diseases  other  than  ALS,  including  Amgen,  Guilford  Pharmaceuticals,  Phytopharm  plc, 
Cephalon, Inc. and Ceregene, Inc. 

Although we do not expect Flocor to have direct competition from other products currently available or that we are aware of that 
are being developed related to Flocor’s ability to reduce blood viscosity in the cardiovascular area, there are a number of anticoagulant 
products  that  Flocor  would  have  to  compete  against,  such  as  tissue  plasminogen  activator,  or  t-PA,  and  streptokinase  (blood  clot 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
dissolving  enzymes)  as  well as  blood  thinners  such  as heparin  and  coumatin,  even  though  Flocor  acts  by  a different  mechanism  to 
prevent damage due to blood coagulation. In the sickle cell disease area, Flocor would compete against companies that are developing 
or marketing other products to treat sickle cell disease, such as Droxia(R) (hydroxyurea) marketed by Bristol-Myers Squibb Co. and 
Dacogen(TM), which is being developed by SuperGen, Inc. Our TranzFect technology will compete against a number of companies 
that  have  developed  adjuvant  products,  such  as  the  adjuvant  QS-21(TM)  marketed  by  Antigenics,  Inc.  and  adjuvants  marketed  by 
Corixa  Corp.  Blizzard’s  products,  if  ever  developed,  will  compete  with  a  number  of  currently  marketed  products,  including  those 
offered by Axon Instruments, Inc., Affymetrix, Inc., Applied Precision, LLC, Perkin Elmer, Inc. and Agilent Technologies, Inc. 

We  Do  Not  Have  the  Ability  to  Manufacture  Any  of  Our  Products  and  Will  Need  to  Rely  upon  Third  Parties  for  the 
Manufacture of Our Clinical and Commercial Product Supplies 

We  do  not  currently  have  the  facilities  or  expertise  to  manufacture  any  of  the  clinical  or  commercial  supplies  of  any  of  our 
products.  Accordingly,  we  will  be  dependent  upon  contract  manufacturers  or  our  strategic  alliance  partners  to  manufacture  these 
supplies, or we will need to acquire the ability to manufacture these supplies ourselves, which could be very difficult, time-consuming 
and costly. We do not have manufacturing supply arrangements for our products, including any of the licensed RNAi technology, the 
drug  candidates  acquired  from  Biorex  or,  with  the  exception  of  the  clinical  supplies  for  the  current  Phase  I  trial,  the  HIV  vaccine 
product that utilizes the HIV vaccine technology that we have licensed from UMMS. There can be no assurance that we will be able to 
secure needed manufacturing supply arrangements, or acquire the ability to manufacture the products ourselves, on attractive terms or 
at all. Delays in, or a failure to, secure these arrangements or abilities could have a materially adverse effect on our ability to complete 
the development of our products or to commercialize them. 

We May Be Unable to Protect Our Intellectual Property Rights, Which Could Adversely Affect the Value of Our Assets 

We believe that obtaining and maintaining patent and other intellectual property rights for our technologies and potential products 
is critical to establishing and maintaining the value of our assets and our business. Although we believe that we have significant patent 
coverage for the technologies that we acquired from Biorex and for our TranzFect technologies, there can be no assurance that this 
coverage will be broad enough to prevent third parties from developing or commercializing similar or identical technologies, that the 
validity  of  our  patents  will  be  upheld  if  challenged  by  third  parties  or  that  our  technologies  will  not  be  deemed  to  infringe  the 
intellectual property rights of third parties. We have a nonexclusive license to a patent owned by UMMS and the Carnegie Institution 
of  Washington  that  claims  various  aspects  of  gene  silencing,  or  genetic  inhibition  by  double-stranded  RNA,  but  there  can  be  no 
assurance that this patent will withstand possible third-party challenges or otherwise protect our technologies from competition. The 
medical  applications  of  the  gene  silencing  technology  and  the  other  technologies  that  we  have  licensed  from  the  UMMS  also  are 
claimed  in  a  number  of  pending  patent  applications,  but  there  can  be  no  assurance  that  these  applications  will  result  in  any  issued 
patents  or  that  those  patents  will  withstand  third-party  challenges  or  protect  our  technologies  from  competition.  Moreover,  we  are 
aware of at least one other issued United States patent claiming broad applications for RNAi, and many patent applications covering 
different methods and compositions in the field of RNAi therapeutics have been and are expected to be filed, and certain organizations 
or researchers may hold or seek to obtain patents that could make it more difficult or impossible for us to develop products based on 
the gene silencing technology that we have licensed. We are aware that at least one of our competitors is seeking patent coverage in 
the RNAi field that could restrict our ability to develop certain RNAi-based therapeutics. 

Any  litigation  brought  by  us  to  protect  our  intellectual  property  rights  or  by  third  parties  asserting  intellectual  property  rights 
against  us,  or  challenging  our  patents,  could  be  costly  and  have  a  material  adverse  effect  on  our  operating  results  or  financial 
condition, make it more difficult for us to enter into strategic alliances with third parties to develop our products, or discourage our 
existing licensees from continuing their development work on our potential products. If our patent coverage is insufficient to prevent 
third parties from developing or commercializing similar or identical technologies, the value of our assets is likely to be materially and 
adversely affected. 

We are sponsoring research at UMMS and Massachusetts General Hospital under agreements that give us certain rights to acquire 
licenses  to  inventions,  if  any,  that  arise  from  that  research,  and  we  may  enter  into  additional  research  agreements  with  those 
institutions,  or  others,  in  the  future.  We  also  have  a  collaboration  and  invention  disclosure  agreement  with  UMMS  under  which 
UMMS  has  agreed  to  disclose  to  us  certain  inventions  it  makes  and  to  give  us  an  option  to  negotiate  licenses  to  the  disclosed 
technologies. There can be no assurance, however, that any such inventions will arise, that we will be able to acquire licenses to any 
inventions under satisfactory terms or at all, or that any licenses will be useful to us commercially. 

 
 
 
 
 
 
 
 
 
We May Incur Substantial Costs from Future Clinical Testing or Product Liability Claims 

If any of our products are alleged to be defective, they may expose us to claims for personal injury by patients in clinical trials of 
our products or by patients using our commercially marketed products. Even if the commercialization of one or more of our products 
is approved by the FDA, users may claim that such products caused unintended adverse effects. We currently do not carry product 
liability insurance covering the use of our products in human clinical trials or the commercial marketing of these products. We are in 
the process of obtaining clinical trial insurance for our planned clinical trial of arimoclomol for the treatment of ALS and will seek to 
obtain  such  insurance  for  any  other  clinical  trials  that  we  conduct,  as  well  as  liability  insurance  for  any  products  that  we  market, 
although there can be no assurance that we will be able to obtain such insurance in the amounts we are seeking or at all. We anticipate 
that our licensees who are developing our products will carry liability insurance covering the clinical testing and marketing of those 
products. However, if someone asserts a claim against us and our insurance or the insurance coverage of our licensees or if their other 
financial  resources  are  inadequate  to  cover  a  successful  claim,  such  successful  claim  could  have  a  material  adverse  effect  on  our 
financial  condition  or  cause  us  to  discontinue  operations.  Even  if  claims  asserted  against  us  are  unsuccessful,  they  may  divert 
management’s attention from our operations and we may have to incur substantial costs to defend such claims. 

We May Be Delisted from the Nasdaq SmallCap Market if Our Future Filings Are Not Timely 

In May 2004, a Nasdaq Listing Qualifications Panel ruled that our common stock would remain listed on the Nasdaq SmallCap 
Market, notwithstanding the fact that we filed our Annual Report on Form 10-K for the year ended December 31, 2003 with the SEC 
after the deadline for its filing. In addition, that Panel also ruled that our common stock would be delisted if we failed to timely file 
any reports with the SEC required for any period ending on or before June 30, 2005, and that we would not be entitled to a hearing 
before a Nasdaq Listing Qualifications Panel with respect to any finding by Nasdaq’s staff of such a filing deficiency. Our inability to 
receive a hearing would make it extremely difficult, if not impossible, to cure any late filing deficiency. If we fail to comply with this 
condition for continued listing and our common stock is delisted from the Nasdaq Small Cap Market, we may seek to list our common 
stock for trading on the American Stock Exchange or a regional stock exchange or to facilitate trading of our common stock in the 
over-the-counter market. If our common stock is delisted from the Nasdaq SmallCap Market, however, there is no assurance that our 
common  stock  will  be  listed for  trading  elsewhere,  and  an  active trading  market  for our  common  stock  may  cease  to  exist  and  the 
delisting could materially and adversely impact the market value of our common stock. 

Our  Anti-Takeover  Provisions  May  Make  It  More  Difficult  to  Change  Our  Management  or  May  Discourage  Others  From 
Acquiring Us and Thereby Adversely Affect Stockholder Value 

We have a stockholder rights plan and provisions in our bylaws that may discourage or prevent a person or group from acquiring 
us without the approval of our board of directors. The intent of the stockholder rights plan and our bylaw provisions is to protect our 
stockholders’ interests by encouraging anyone seeking control of our company to negotiate with our board of directors. 

We have a classified board of directors, which requires that at least two stockholder meetings, instead of one, will be required to 
effect  a  change  in  the  majority  control  of  our  board  of  directors.  This  provision  applies  to  every  election  of  directors,  not  just  an 
election occurring after a change in control. The classification of our board increases the amount of time it takes to change majority 
control of our board of directors and may cause our potential purchasers to lose interest in the potential purchase of us, regardless of 
whether our purchase would be beneficial to us or our stockholders. The additional time and cost to change a majority of the members 
of our board of directors makes it more difficult and may discourage our existing stockholders from seeking to change our existing 
management in order to change the strategic direction or operational performance of our company. 

Our bylaws provide that directors may only be removed for cause by the affirmative vote of the holders of at least a majority of the 
outstanding  shares  of  our  capital  stock  then  entitled  to  vote  at  an  election  of  directors.  This  provision  prevents  stockholders  from 
removing any incumbent director without cause. Our bylaws also provide that a stockholder must give us at least 120 days notice of a 
proposal  or  director  nomination  that  such  stockholder  desires  to  present  at  any  annual  meeting  or  special  meeting  of  stockholders. 
Such  provision  prevents  a  stockholder  from  making  a  proposal  or  director  nomination  at  a  stockholder  meeting  without  us  having 
advance notice of that proposal or director nomination. This could make a change in control more difficult by providing our directors 
with  more  time  to  prepare  an  opposition  to  a  proposed  change  in  control.  By  making  it  more  difficult  to  remove  or  install  new 
directors, the foregoing bylaw provisions may also make our existing management less responsive to the views of our stockholders 
with respect to our operations and other issues such as management selection and management compensation. 

 
 
 
 
 
 
 
 
 
 
Our Outstanding Options and Warrants and the Registrations of Our Shares Issued in the Global Genomics Merger and Our 
Recent Private Financings May Adversely Affect the Trading Price of Our Common Stock 

As of December 31, 2004, there were outstanding stock options and warrants to purchase approximately 14.5 million shares of our 
common stock at exercise prices ranging from $0.01 to $2.94 per share. Our outstanding options and warrants could adversely affect 
our ability to obtain future financing or engage in certain mergers or other transactions, since the holders of options and warrants can 
be expected to exercise them at a time when we may be able to obtain additional capital through a new offering of securities on terms 
more favorable to us than the terms of outstanding options and warrants. For the life of the options and warrants, the holders have the 
opportunity to profit from a rise in the market price of our common stock without assuming the risk of ownership. To the extent the 
trading price of our common stock at the time of exercise of any such options or warrants exceeds the exercise price, such exercise 
will also have a dilutive effect on our stockholders. 

In  August  2003,  we  registered  with  the  SEC  for  resale  by  the  holders  a  total  of  14,408,252  shares  of  our  outstanding  common 
stock  and  an  additional  3,848,870  shares  of  our  common  stock  issuable  upon  exercise  of  outstanding  options  and  warrants,  which 
shares  and  options  and  warrants  were  issued  primarily  in  connection  with  our  merger  with  Global  Genomics  and  the  $5.4  million 
private equity financing that we completed in May 2003. In December 2003, we registered a total of 6,113,448 shares of our common 
stock, consisting of the 5,175,611 shares issued, or that are issuable upon exercise of the warrants issued, in connection with the $8.7 
million private equity financing that we completed in September 2003, and an additional 937,837 shares of our common stock that we 
issued,  or  that  are  issuable  upon  the  exercise  of  warrants  that  we  issued,  to  certain  other  third  parties.  In  April  2004,  we  became 
ineligible  to  continue  to  use  Form  S-3  for  both  of  these  registrations,  so  that  the  holders  of  these  shares  could  no  longer  sell  their 
shares  under  these  registrations.  Our  ineligibility  to  register  resales  on  Form  S-3  may  have  created  liability  under  certain  of  our 
registration rights agreements if we are not deemed to have amended certain existing registrations in a reasonable period of time so as 
to permit the holders to again be able to sell their shares under those registrations. We are in the process of reinstating the registrations 
so as to permit the holders to again be able to sell their shares under these registrations. In November 2004, we registered 4,000,000 
shares  of  our  common  stock  and  an  additional  3,080,000  shares  of  our  common  stock  issuable  upon  the  exercise  of  warrants  in 
connection with the $4,000,000 private equity financing that we completed in October 2004, and an additional 1,550,000 shares of our 
common  stock  issued  or  issuable  upon  exercise  of  warrants  to  other  third  parties.  In  February  2005,  we  filed  with  the  SEC  a 
registration  statement  covering  17,334,494  shares  of  our  common  stock  and  an  additional  9,909,117  shares  of  our  common  stock 
issuable  upon  the  exercise  of  warrants  in  connection  with  the  $21.3  million  private  equity  financing  that  we  completed  in  January 
2005.  Both  the  availability  for  public  resale  of  these  various  shares  and the  actual  resale  of  these shares  could  adversely  affect  the 
trading price of our common stock. 

We May Issue Preferred Stock in the Future, and the Terms of the Preferred Stock May Reduce the Value of Our Common 
Stock 

We are authorized to issue up to 5,000,000 shares of preferred stock in one or more series. Our board of directors may determine 
the terms of future preferred stock offerings without further action by our stockholders. If we issue preferred stock, it could affect your 
rights or reduce the value of our outstanding common stock. In particular, specific rights granted to future holders of preferred stock 
may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights, sinking fund provisions, and 
restrictions on our ability to merge with or sell our assets to a third party. 

Changes in Stock Option Accounting Rules May Adversely Impact Our Reported Operating Results, Our Stock Price and Our 
Competitiveness in the Employee Marketplace 

In December 2004, the Financial Accounting Standards Board published new rules that will require companies in 2005 to record 
all stock-based employee compensation as an expense. The new rules apply to stock options grants, as well as a range of other stock-
based  compensation  arrangements,  including  restricted  share  plans,  performance-based  awards,  share  appreciation  rights,  and 
employee share purchase plans. We will have to apply the new financial accounting rules beginning in the third quarter of 2005. We 
have depended in the past upon compensating our officers, directors, employees and consultants with such stock-based compensation 
awards in order to limit our cash expenditures and to attract and retain officers, directors, employees and consultants. Accordingly, if 
we continue to grant stock options or other stock-based compensation awards to our officers, directors, employees, and consultants 
after the new rules apply to us, our future earnings, if any, will be reduced (or our future losses will be increased) by the expenses 
recorded for those grants. These compensation expenses may be larger than the compensation expense that we would be required to 
record were we able to compensate these persons with cash in lieu of securities. The expenses we may have to record as a result of 
future options grants may be significant and may materially negatively affect our reported financial results. The adverse effects that 
the new accounting rules may have on our future financial statements should we continue to rely heavily on stock-based compensation 

 
 
 
 
 
 
 
 
may reduce our stock price and make it more difficult for us to attract new investors. In addition, reducing our use of stock plans to 
reward  and  incentivize  our  officers,  directors  and  employees  could  result  in  a  competitive  disadvantage  to  us  in  the  employee 
marketplace. 

We May Experience Volatility in Our Stock Price, Which May Adversely Affect the Trading Price of Our Common Stock 

The market price of our common stock has experienced significant volatility in the past and may continue to experience significant 
volatility from time to time. Our stock price has ranged from $0.21 to $3.74 per share over the past three years. Factors such as the 
following may affect such volatility: 

•  Our quarterly operating results.  

•  Announcements of regulatory developments or technological innovations by us or our competitors. 

•  Government regulation of drug pricing.  

•  Developments in patent or other technology ownership rights.  

•  Public concern regarding the safety of our products.  

Other  factors which  may  affect  our  stock price  are  general  changes  in the  economy,  financial  markets  or  the  pharmaceutical  or 

biotechnology industries. 

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk 

Our exposure to market risk is limited primarily to interest income sensitivity, which is affected by changes in the general level of 
United States interest rates, particularly because a significant portion of our investments are in short-term debt securities issued by the 
U.S.  government  and  institutional  money  market  funds.  The  primary  objective  of  our  investment  activities  is  to  preserve  principal 
while  at  the  same  time  maximizing  the  income  received  without  significantly  increasing  risk.  Due  to  the  nature  of  our  short-term 
investments,  we  believe  that  we  are  not  subject  to  any  material  market  risk  exposure.  We  do  not  have  any  derivative  financial 
instruments or foreign currency instruments. 

Item 8.  Financial Statements and Supplementary Data 

Our consolidated financial statements and supplemental schedule and notes thereto as of December 31, 2004 and 2003, and for 
each of the three years ended December 31, 2004, 2003 and 2002, together with the independent registered public accounting firms’ 
reports thereon, are set forth on pages F-1 to F-24 of this Annual Report. 

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

Effective as of January 20, 2004, the Audit Committee of our board of directors dismissed Ernst & Young LLP, or E&Y, as our 
independent auditors. Effective as of January 30, 2004, our Audit Committee engaged PricewaterhouseCoopers LLP, or PwC, as our 
new  independent  auditors  and  to  audit  our  financial  statements  for  the  year  ended  December  31,  2003.  During  the  years  ended 
December 31, 2002 and December 31, 2001 and the subsequent period through January 30, 2004, neither we nor anyone on our behalf 
consulted  with  PwC  regarding  either  (i)  the  application  of  accounting  principles  to  a  specified  transaction,  either  completed  or 
proposed or the type of audit opinion that might be rendered on our financial statements, and either a written report was provided to us 
or oral advice was provided that PwC concluded was an important factor considered by us in reaching a decision as to the accounting, 
auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement, as that term is defined in Item 
304(a)(1)(iv)  of  SEC  Regulation  S-K  and  the  related  instructions  thereof,  or  a  reportable  event,  as  that  term  is  defined  in  Item 
304(a)(1)(v) of SEC Regulation S-K. 

On April 12, 2004, our Audit Committee dismissed PwC as our independent auditors. PwC was dismissed prior to completing its 
audit  procedures  and  did  not  issue  any  report  on  our  financial  statements.  On  April  14,  2004,  our  Audit  Committee  engaged  BDO 
Seidman, LLP, or BDO, which completed its client acceptance process on that date, to serve as our independent auditors and to audit 
our financial statements for the year ended December 31, 2003. Based on our desire to have the audit of these financial statements 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
completed in as expeditious a fashion as possible, our Audit Committee had concluded that it was in our best interests to dismiss PwC 
and to engage new independent accountants to complete the audit of these financial statements. 

During the period from January 30, 2004 through April 12, 2004, there had been no disagreements with PwC on any matter of 
accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements if not resolved 
to the satisfaction of PwC would have caused it to make reference thereto in its report had it completed an audit and issued a report on 
our  financial  statements,  except  as  disclosed  in  the  sixth  paragraph  below.  In  addition,  for  the  same  period,  there  had  been  no 
reportable  events  (as  defined  in  SEC  Regulation  S-K  Item  304(a)(1)(v)),  except  as  described  in  the  sixth  paragraph  below.  We 
recorded  all  material  adjustments  that  were  communicated  to  us  by  PwC  during  PwC’s  engagement  or  to  BDO  prior  to  BDO’s 
engagement. 

In our Current Report on Form 8-K filed with the SEC on April 1, 2004, we indicated that we were reviewing, with the assistance 
of  PwC,  the  accounting  treatment  of our  July  2002  acquisition of  Global  Genomics  and Global Genomics’  assets  at  the  time  of  its 
merger  with  us,  which  included  Global  Genomics’  investments  in  two  genomics  companies,  Blizzard  and  Psynomics.  These 
investments had an aggregate carrying value on our financial statements, as of September 30, 2003, of approximately $5.87 million. 
This accounting review delayed the completion of our financial statements for the year ended December 31, 2003 and the filing with 
the SEC of our Annual Report on Form 10-K. 

Although we had previously disclosed, in our Current Report on Form 8-K dated January 16, 2004, that we would write off our 
investments in Blizzard and Psynomics in the quarter ended December 31, 2003, the following principal issues were identified during 
our accounting review: 

•  Whether a portion of the purchase price in our July 2002 merger with Global Genomics (accounted for as a purchase of a group 
of  assets,  not  a  business  combination)  should  have  been  allocated  to  an  acquired  assembled  workforce,  which  would  have 
reduced  the  amount  of  the  purchase  price  allocated  to  the  Blizzard  and  Psynomics  investments  ($7.3  million  and  $78,000, 
respectively) and whether the amount originally determined to be the fair value of the Blizzard investment was overstated. 

•  Whether an other-than-temporary impairment charge should have been taken by us against the appropriate carrying value of the 

Blizzard investment earlier than in the fourth quarter of 2003. 

The resolution of these issues in a manner that would result in a different accounting than originally reported would have had no 
effect on our cash or working capital position for any accounting period nor would it have had a material effect on our net worth as of 
December 31, 2003. One possible resolution could, however, have resulted in our net loss for the year ended December 31, 2002 being 
materially larger than that reported by us in our financial statements for that year and in our reporting a net worth significantly lower 
than the net worth we reported in our financial statements for that year. Such a resolution, in turn, could have required a restatement of 
those financial statements as well as our unaudited financial statements for the quarterly periods ended March 31, 2003, June 30, 2003 
and  September  30,  2003.  Other  possible  resolutions  could  have  resulted  in  the  recognition  of  an  other-than-temporary  impairment 
charge  in  an  earlier  2003  quarter  and  could  have  required  a  restatement  of  our  unaudited  financial  statements  for  that  and  any 
subsequent quarter. However, the impact of the resolution of these issues on our net loss for the year ended December 31, 2002 and/or 
subsequent  periods  were  not  readily  estimable  by  us,  because  it  would  have  depended  on  the  amount  of  the  purchase  price  to  be 
allocated to other assets and the nature of those assets and the valuation of our investment in Blizzard as of December 31, 2002 and as 
of  the  end  of  each  of  the  three  subsequent  quarters,  each  of  which  would  be  dependent  upon  various  assumptions  and  valuation 
methods. 

As a result of the issues that were brought to our attention by PwC, we thoroughly re-reviewed, in late March and early April 2004, 
the prior accounting treatment for the Global Genomics acquisition and the Blizzard investment. This review included, among other 
things, (i) our submission of additional documentation to PwC, (ii) discussions of these issues by our Audit Committee with PwC, (iii) 
discussions between PwC and us, (iv) discussions between E&Y and us and (v) the retention of a nationally respected valuation firm 
to review certain of the methodologies that were used by us in connection with the purchase price allocation for Global Genomics, 
including  amounts,  if  any,  that  would  be  attributable  to  an  acquired  assembled  workforce  and  methodologies  utilized  in  our  other-
than-temporary impairment analyses and to assess what amount of the purchase price for Global Genomics could appropriately have 
been attributable to an acquired assembled work force, if any. 

Following our re-review of the accounting treatment for the purchase price for the Global Genomics merger and the carrying value 
of the Blizzard investment, we advised PwC, in early April 2004, that we continued to believe that our prior accounting treatment was 

 
 
 
 
 
 
 
 
 
 
correct  in  all  material  respects.  We  also  advised  PwC  that  our  valuation  firm  had  concluded  that,  even  if  any  amount  were  to  be 
allocated to an acquired assembled workforce, the valuation of such an acquired workforce would be only $250,000. 

During  the  course  of  its  engagement  PwC  informed  us  that  it  disagreed  with  the  timing  of  the  fourth  quarter  2003  other-than-
temporary impairment charge that we had recorded related to our investment in Blizzard. PwC also informed us that PwC needed to 
significantly expand the scope of its audit procedures with respect to the matters identified in the fourth paragraph above, including 
procedures designed to understand the impact, if any, of certain third party comments regarding indicators of value, and that it had not 
completed audit procedures regarding the nature and timing of our impairment of Blizzard and the original purchase price allocation 
upon our acquisition of Global Genomics in 2002. PwC has advised us that, as a result of their dismissal, they were unable to complete 
their expanded audit procedures, and as a consequence, PwC had not formed a view as to whether our accounting for these matters 
was in conformity with accounting principles generally accepted in the United States. 

E&Y’s  report  on  our  financial  statements  for  the  years  ended  December  31,  2001  and  December  31,  2002  did  not  contain  any 
adverse opinion or a disclaimer of an opinion or any qualification as to uncertainty, audit scope or accounting principles. In connection 
with E&Y’s audits for those years there were no “disagreements” or “reportable events” as defined in Item 304 of SEC Regulation S-
K, except as described in this paragraph. However, we were informed by E&Y, in April 2004, that, until such time as the impact of the 
third party comments regarding indicators of value concerning Blizzard, referred to by PwC, were further evaluated, E&Y was not 
able to conclude as to whether the prior accounting treatment was appropriate in all material respects. E&Y advised us that, depending 
upon  the  outcome  of  those  procedures,  the  financial  statements  for  the  year  ended  December  31,  2002,  audited  by  E&Y,  or  the 
unaudited interim financial statements for the quarters ended March 31, June 30, and September 30, 2003, might require restatement. 
However, E&Y has not withdrawn its opinion on our 2002 audited financial statements. 

A special committee consisting of two of our Audit Committee members subsequently performed an evaluation of the impact of 
the  third  party  comments  regarding  indicators  of  value  concerning  Blizzard.  This  special  committee  concluded  that  we  did  not 
withhold  from  E&Y  any  documents  that  would  have  changed  the  conclusions  reached  by  E&Y  relative  to  the  carrying  value  of 
Blizzard  and  its  audit  of  our  financial  statements.  After  reviewing  this  evaluation,  E&Y  advised  us  that  it  had  concluded  that  our 
audited 2002 financial statements and our unaudited interim financial statements for the quarters ended March 31, 2003 and June 30, 
2003 did not require any restatement. Accordingly, no information has come to the Company’s attention that would lead us to believe 
that an investor could no longer rely on E&Y’s opinion on our 2002 audited financial statements. 

In connection with the preparation of our financial statements for the year ended December 31, 2003, we believed that we had a 
reasonable basis for taking the Blizzard impairment charge in the fourth quarter of 2003; however, after further review of the issues 
relating to the timing of this charge, we determined in May 2004 that this charge should have been taken in the third quarter of 2003. 
We filed an amended Form 10-Q for the period ended September 30, 2003 in May 2004 to reflect the impairment charges taken during 
that period. 

During  our  two  fiscal  years  ended  December  31,  2002  and  December  31,  2003  and  the  interim  period  through  the  date  of  our 
engagement of BDO to perform the audit of our financial statements for the year ended December 31, 2003, we did not consult with 
BDO regarding (i) the application of accounting principles to a specified transaction, either completed or proposed or the type of audit 
opinion that might be rendered on our financial statements, and either a written report was provided to us or oral advice was provided 
that  BDO  concluded  was  an  important  factor  considered  by  us  in  reaching  a  decision  as  to  an  accounting,  auditing  or  financial 
reporting  issue  or  (ii)  any  matter  that  was  either  the  subject  of  a  disagreement  (as  defined  in  paragraph  304(a)(1)(iv)  of  SEC 
Regulation  S-K  and  the  related  instructions  to  this  item)  or  a  reportable  event  (as  described  in  paragraph  304(a)(1)(v)  of  SEC 
Regulation S-K), except as follows: 

•  On  April  2,  2004,  our  Audit  Committee  engaged  BDO  to  perform  agreed-upon  procedures  with  respect  to  our  financial 
statements for the year ended December 31, 2003. Due to our Audit Committee’s concerns that the concurrent involvement of 
two auditing firms might create the appearance that we were shopping for a particular audit opinion, the terms of our April 2, 
2004 engagement of BDO stated that BDO was not to conduct a compilation, review or audit, but rather was to conduct only 
certain agreed upon procedures. We agreed with BDO that the procedures would be conducted solely in order to assist BDO in 
completing a potential future audit of our financial statements in the event the Audit Committee subsequently engaged BDO to 
opine  on  our  financial  statements.  Since  the  agreed  upon  procedures  specified  in  our  engagement  agreement  were  to  be 
conducted in preparation for a possible future audit, they included a majority of the procedures that would have been necessary 
in order for BDO to opine with respect to our financial statements. The specific procedures were proposed by BDO and were 
jointly accepted by BDO and us without modification. We have been advised by BDO that, as of April 14, 2004, the date on 
which we engaged BDO to become our independent auditor, BDO had completed approximately 64% of the hours that they 

 
 
 
 
 
 
 
 
eventually  worked  to  complete  their  audit,  but  a  significant  portion  of  the  manager  and  partner  review  had  not  yet  been 
completed. 

•  Subsequent  to  engaging  BDO  to  perform  these  agreed-upon  procedures,  we  consulted  with  BDO  concerning  the  need  to 
include separate audited financial statements of Blizzard in our Annual Report for the year ended December 31, 2003. BDO 
orally advised us that separate audited Blizzard financial statements were required to be included in this Annual Report. This 
advice was consistent with the advice previously received by us from PwC on this issue, no disagreement on this issue existed 
between PwC and us, and we subsequently filed these financial statements in our Annual Report for the year ended December 
31, 2003, together with our financial statements. 

•  During the course of BDO’s performance of the above agreed-upon procedures, we did not solicit or receive any oral or written 
opinion  from  BDO  with  respect  to  the  proper  accounting  treatment  for  the  allocation  of  the  purchase  price  paid  by  us  in 
connection with our merger with Global Genomics or the subsequent carrying value of our investment in Blizzard. However, 
we did discuss with BDO our views on the proper accounting treatment for these items and provided BDO with certain of our 
accounting records, a valuation analysis prepared by a valuation firm in 2002 utilized by management in connection with its 
allocation of the purchase price for the Global Genomics merger and an analysis prepared in April 2004 by another valuation 
firm covering certain aspects of the allocation of that purchase price and the subsequent carrying value of Blizzard. 

Item 9A.  Controls and Procedures 

An evaluation was performed by our management team, with the participation of our Chief Executive Officer and Chief Financial 
Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered 
by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure 
controls  and  procedures  were  effective  as  of  December  31,  2004  to  provide  reasonable  assurance  that  information  required  to  be 
disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the 
time periods specified in the Securities and Exchange Commission rules and forms. 

There were no changes in our internal control over financial reporting that occurred during the year ended December 31, 2004, that 

materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our board of directors has determined that Messrs. Link, Rubinfeld, Selter and Wennekamp are “independent” under the current 
independence standards of both the Nasdaq Stock Market and the SEC, and have no material relationships with us (either directly or as 
a partner, shareholder or officer of any entity) which could be inconsistent with a finding of their independence as members of our 
board  of  directors  or  as  the  members  of  our  Audit  Committee.  In  making  these  determinations,  our  board  of  directors  has  broadly 
considered all relevant facts and circumstances, recognizing that material relationships can include commercial, banking, consulting, 
legal, accounting, and familial relationships, among others. 

Our board of directors has determined that Mr. Selter, one of the independent directors serving on our Audit Committee, also is an 

audit committee financial expert as defined by the SEC’s rules. 

Section 16(a) Beneficial Ownership Reporting Compliance 

Our  executive  officers  and  directors  and  any  person  who  owns  more  than  10%  of  our  outstanding  shares  of  common  stock  are 
required by Section 16(a) of the Securities Exchange Act to file with the SEC initial reports of ownership and reports of changes in 
ownership of our common stock and to furnish us with copies of those reports. Based solely on our review of copies of reports we 
have  received  and  written  representations  from  certain  reporting  persons,  we  believe  that  all  Section  16(a)  filing  requirements 
applicable to our directors and executive officers and greater than 10% shareholders for 2003 were complied with, except that reports 
for the following transactions were filed late due to administrative oversights: 

•  Grants of stock options to Messrs. Ignarro, Rubinfeld, Link, Selter and Wennekamp, directors of the Company, in July 2004; 

and 

•  The acquisition by Mr. Wennekamp of shares of our common stock in August 2004. 

Forms 4 reporting each of the above transactions were subsequently filed by these individuals. 

Code of Ethics 

We  have  adopted  a  Code  of  Ethics  applicable  to  our  principal  executive  officer,  principal  financial  officer,  and  principal 

accounting officer or controller, a copy of which is filed as an exhibit to this Form 10-K.

Compensation of Directors 

Periodically,  our  board  of  directors  reviews  our  director  compensation  policies  and,  from  time  to  time,  makes  changes  to  such 
policies based on various criteria the board deems relevant. During 2004, directors who were employees of our company received no 
compensation for their service as directors or as members of board committees. 

During  2004,  our  non-employee  directors  received  a  quarterly  retainer  of  $1,500  and  a  fee  of  $1,500  for  each  board  meeting 
attended ($750 for meetings attended by teleconference and for board actions taken by unanimous written consent) and $750 for each 
committee meeting attended. Non-employee directors who chair the board or a board committee receive an additional $250 for each 
meeting attended as the chair. In May 2004 we made a payment of $7,500, plus reimbursement of certain expenses, to each of Messrs. 
Selter and Wennekamp in connection with their services as members of our Audit Committee. We grant options to purchase 15,000 
shares of common stock at an exercise price equal to the current market value of our common stock to each non-employee director 
annually,  usually  in  the  summer  of  each  year.  Such  option  grants  are  made  subject  to  vesting  in  annual  increments  of  1/3rd  each, 
subject to the director remaining as a director.

Perquisites 

In  general,  we  afford  our  directors  and  executive  officers  no  perquisites  apart  from  the  compensation  and  stock  option  benefits 
described above and any benefits specifically provided for under the terms of any employment agreement as described below. We do, 
however, bear the cost of outside counsel employed by us to assist directors and executive officers in preparing reports of changes in 
beneficial  ownership  under  Section  16  of  the  Securities  Exchange  Act  of  1934  and  other  Section  16  compliance  matters.  We  also 
permit Mr. Kriegsman, our President and Chief Executive Officer, and our directors to fly first-class for business travel, which is an 
exception to our usual practice for business travel by our officers and employees. 

Employment Agreements; Change in Control Agreements 

Employment Agreement with Steven A. Kriegsman 

Mr. Kriegsman is employed as our Chief Executive Officer pursuant to an employment agreement that was amended and restated 
as  of  June  10,  2003  to  continue  through  July  15,  2006.  The  employment  agreement  will  automatically  renew  in  July  2006  for  an 
additional one-year period, unless either Mr. Kriegsman or we elect not to renew it. 

Under his employment agreement, Mr. Kriegsman is entitled to an annual base salary of $360,000. Our board of directors (or its 
Compensation Committee) will review the base salary annually and may increase (but not decrease) it in its sole discretion, and on 
March 14, 2005, the Compensation Committee determined to increase Mr. Kriegsman’s base salary to $400,000, effective January 1, 
2005. In addition to his annual salary, Mr. Kriegsman is eligible to receive an annual bonus as determined by our board of directors (or 
its Compensation Committee) in its sole discretion, but not to be less than $150,000. Pursuant to his employment agreement with us, 
we have agreed that he shall serve on a full-time basis as our Chief Executive Officer and that he may continue to serve as President of 
the Kriegsman Group only so long as necessary to complete certain current assignments. 

Mr. Kriegsman is eligible to receive grants of options to purchase shares of our common stock. The number and terms of those 
options,  including  the  vesting  schedule,  will  be  determined  by  our  board  of  directors  (or  its  Compensation  Committee)  in  its  sole 
discretion. 

Under Mr. Kriegsman’s employment agreement, we have agreed that, if he is made a party, or threatened to be made a party, to a 
suit or proceeding by reason of his service to us, we will indemnify and hold him harmless from all costs and expenses to the fullest 
extent permitted or authorized by our certificate of incorporation or bylaws, or any resolution of our board of directors, to the extent 
not inconsistent with Delaware law. We also have agreed to advance to Mr. Kriegsman such costs and expenses upon his request if he 
undertakes  to repay such  advances  if  it  ultimately  is  determined  that he  is  not  entitled  to  indemnification with respect  to  the  same. 
These  employment  agreement  provisions  are  not  exclusive  of  any  other  rights  to  indemnification  to  which  Mr.  Kriegsman  may  be 
entitled and are in addition to any rights he may have under any policy of insurance maintained by us. 

In  the  event  we  terminate  Mr.  Kriegsman’s  employment  without  “cause”  (as  defined),  or  if  Mr.  Kriegsman  terminates  his 
employment with “good reason” (as defined), (i) we have agreed to pay Mr. Kriegsman a lump-sum equal to his salary and prorated 
minimum annual bonus through to his date of termination, plus his salary and minimum annual bonus for a period of two years after 
his  termination  date,  or  until  the  expiration  of  the  amended  and  restated  employment  agreement,  whichever  is  later,  (ii)  he  will  be 
entitled to immediate vesting of all stock options or other awards based on our equity securities, and (iii) he will also be entitled to 
continuation of his life insurance premium payments and continued participation in any of our health plans through to the later of the 
expiration of the amended and restated employment agreement or 24 months following his termination date. Mr. Kriegsman will have 
no obligation in such events to seek new employment or offset the severance payments to him by the Company by any compensation 
received from any subsequent reemployment by another employer. 

Under Mr. Kriegsman’s employment agreement, he and his affiliated company, The Kriegsman Group, are to provide us during 
the term of his employment with the first opportunity to conduct or take action with respect to any acquisition opportunity or any other 
potential transaction identified by them within the biotech, pharmaceutical or health care industries and that is within the scope of the 
business  plan  adopted  by  our  board  of  directors.  Mr.  Kriegsman’s  employment  agreement  also  contains  confidentiality  provisions 
relating  to  our  trade  secrets  and  any  other  proprietary  or  confidential  information,  which  provisions  shall  remain  in  effect  for  five 
years after the expiration of the employment agreement with respect to proprietary or confidential information and for so long as our 
trade secrets remain trade secrets. 

 
 
 
 
 
 
 
 
 
 
 
 
Change in Control Agreement with Steven A. Kriegsman 

Mr. Kriegsman’s employment agreement contains no provision for payment to him in the event of a change in control of CytRx. If, 
however,  a  change  in  control  (as  defined  in  our  2000  Long-Term  Incentive  Plan)  occurs  during  the  term  of  the  employment 
agreement,  and  if,  during  the  term  and  within  two  years  after  the  date  on  which  the  change  in  control  occurs,  Mr.  Kriegsman’s 
employment is terminated by us without cause or by him for good reason (each as defined in his employment agreement), then, to the 
extent that any payment or distribution of any type by us to or for the benefit of Mr. Kriegsman resulting from the termination of his 
employment is or will be subject to the excise tax imposed under Section 4999 of the Internal Revenue Code of 1986, as amended, we 
have agreed to pay Mr. Kriegsman, prior to the time the excise tax is payable with respect to any such payment (through withholding 
or otherwise), an additional amount that, after the imposition of all income, employment, excise and other taxes, penalties and interest 
thereon, is equal to the sum of (i) the excise tax on such payments plus (ii) any penalty and interest assessments associated with such 
excise tax. 

Employment Agreement with Matthew Natalizio 

Matthew Natalizio became our Chief Financial Officer on July 12, 2004 pursuant to a one-year employment agreement with us. 
Mr. Natalizio is entitled under his employment agreement to an annual base salary of $175,000 and is eligible to receive an annual 
bonus  as determined  by our board  of  directors (or  its  Compensation  Committee)  in  its  sole  discretion. As  an  incentive  to  enter  the 
employment  agreement,  Mr.  Natalizio  was  granted  as  of  July  12,  2004  a  ten-year,  nonqualified  option  under  our  2000  Long-Term 
Incentive Plan to purchase 100,000 shares of our common stock at a price of $1.11 per share. This option will vest as to 1/3rd of the 
shares covered thereby on each of the first three anniversaries of the employment agreement, provided that Mr. Natalizio remains in 
our continuous employ. 

In the event we terminate Mr. Natalizio’s employment without cause (as defined), we have agreed to pay him a lump-sum equal to 
his accrued but unpaid salary and vacation, plus an amount equal to 1/360th of his salary for each four days (prorated for any period of 
less than four days) that he was employed prior to the date of his termination. 

Employment Agreement with Jack R. Barber, Ph.D.

employment agreement with us. Under his employment agreement, Dr. Barber is entitled to an annual base salary of $230,000 and is 
eligible to receive an annual bonus as determined by our board of directors (or its Compensation Committee) in its sole discretion. As 
an incentive to enter the employment agreement, Dr. Barber was granted as of July 6, 2004 a ten-year, nonqualified option under our 
2000 Long-Term Incentive Plan to purchase 100,000 shares of our common stock at a price of $1.13 per share. This option will vest as 
to 1/3rd of the shares covered thereby on each of the first three anniversaries of the employment agreement, provided that Dr. Barber 
remains in our continuous employ. 

In the event we terminate Dr. Barber’s employment without cause (as defined), we have agreed to pay him a lump-sum equal to his

Mark A. Tepper, Ph.D., became President of our CytRx Laboratories, Inc. subsidiary on September 17, 2003 pursuant to a two-
year employment agreement with CytRx Laboratories, Inc. Under his employment agreement, Dr. Tepper is entitled to an annual base 
salary  of $200,000  and  is  eligible  to receive  an  annual  bonus  targeted  at  $50,000 based  upon achievement  of  certain  milestones as 
agreed  upon  by  Dr.  Tepper  and  the  board  of  directors  of  CytRx  Laboratories,  Inc.  As  an  incentive  to  enter  into  the  employment 
agreement,  Dr.  Tepper  was  granted  ten-year,  nonqualified  options  under  our  2000  Long-Term  Incentive  Plan  to  purchase  120,000 
shares  of  our  common  stock  at  a  price  of  $2.41  per  share  and  a  separate  ten-year  nonqualified  option  under  the  Plan  to  purchase

Compensation Committee Interlocks and Insider Participation in Compensation Decisions 

There are no “interlocks,” as defined by the SEC, with respect to any member of the compensation committee. Joseph Rubinfeld, 

Ph.D., Marvin R. Selter and Richard L. Wennekamp are the current members of the compensation committee. 

Item 12.  Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters 

Based  solely  upon  information  made  available  to  us,  the  following  table  sets  forth  information  with  respect  to  the  beneficial 
ownership of our common stock as of January 31, 2005 by (1) each person who is known by us to beneficially own more than five 
percent of the common stock; (2) each director; (3) the named executive officers listed in the Summary Compensation Table under 
Item 11; and (4) all executive officers and directors as a group. 

Beneficial ownership is determined in accordance with the SEC rules. Shares of common stock subject to any warrants or options 
that  are  presently  exercisable,  or  exercisable  within  60  days  of  January  31,  2005,  which  are  indicated  by  footnote,  are  deemed 
outstanding for the purpose of computing the percentage ownership of the person holding the warrants or options, but are not treated 
as outstanding for the purpose of computing the percentage ownership of any other person. The percentage ownership reflected in the 
table  is  based  on  57,048,449  shares  of  our  common  stock  outstanding  as  of  January  31,  2005.  Except  as  otherwise  indicated,  the 
holders listed below have sole voting and investment power with respect to all shares of common stock shown, subject to applicable 
community property laws. An asterisk represents beneficial ownership of less than 1%.

Item 13.  Certain Relationships and Related Transactions 

Since July 16, 2002, Steven A. Kriegsman has been our Chief Executive Officer and one of our directors. In July 2002, we entered 
into an agreement with the Kriegsman Capital Group, or KCG, an affiliate of Mr. Kriegsman, whereby KCG agreed to provide us with 
office space and certain administrative services. In 2003, we paid a total of approximately $70,000 to KCG under this agreement. The 
charges  were  determined  based  upon  actual  space  used  and  estimated  percentages  of  employee  time  used.  In  October  2003,  the 
services and facilities agreement with KCG was terminated as substantially all of the on-going operations of KCG have ceased. The 
obligations under the facility lease at our headquarters were transferred from KCG to us in July 2003. We believe that the terms under 
which we paid KCG for rent and other expenses are at least as favorable to us as could have been obtained from an unrelated third 
party. 

We entered into an agreement, dated as of July 17, 2003 (and subsequently amended on October 18, 2003), with Louis Ignarro, 
Ph.D., one of our current directors. Pursuant to the agreement, Dr. Ignarro agreed to serve as our Chief Scientific Spokesperson to the 
medical and financial communities. As payment for his services, Dr. Ignarro was granted a non-qualified stock option under our 2000 
Long-Term Incentive Plan to purchase 350,000 registered shares of our common stock at an exercise price equal to $1.89, the closing 
price for our common stock on Nasdaq on the date of grant. The option has a term of seven years, and from July 17, 2003 to October 
17, 2003, vested monthly at the rate of 4,839 shares for each day of services provided by Dr. Ignarro in that month and, from October 
18, 2003, vests monthly at a rate of 15,975 shares for the remaining term of the agreement. Either party may terminate the agreement 
at any time, and any unvested shares under the option as of the date of termination of the agreement will be cancelled. As of January 
31, 2005, 270,117 shares of common stock under the option had vested. 

Item 14.  Principal Accountant Fees and Services 

BDO  Seidman,  LLP,  or  BDO,  serves  as  our  independent  accountants  and  audited  our  financial  statements  for  the  years  ended 
December  31,  2003  and  2004.  Ernst  &  Young  LLP,  or  E&Y,  previously  served  as  our  independent  accountants  and  audited  our 
financial statements for the year ended December 31, 2002.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1.  Nature of Business 

CytRx  Corporation  (“CytRx”  or  the  “Company”)  is  a  biopharmaceutical  research  and  development  company,  based  in  Los 
Angeles,  California,  with  a  development-stage  subsidiary,  CytRx  Laboratories,  Inc.  (the  “Subsidiary”),  based  in  Worcester, 
Massachusetts (see Note 11). The Company’s small molecule therapeutics efforts include the clinical development of three, oral drug 
candidates that it acquired in October 2004, as well as a drug discovery operation conducted by the Subsidiary. The Company owns 
the rights to a portfolio of technologies, including ribonueleic acid interference (RNAi or gene silencing) technology in the treatment 
of specified diseases, including those within the areas of amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease), obesity and type 
2 diabetes and human cytomegalovirus (CMV), as well as a DNA-based HIV vaccine technology and a cancer therapeutic technology. 
In addition, the Company has entered into strategic alliances with third parties to develop several of the Company’s other products. 

On  October  4,  2004,  CytRx  acquired  all  of  the  clinical  and  pharmaceutical  and  related  intellectual  property  assets  of  Biorex 
Research & Development, RT, or Biorex, a Hungary-based company focused on the development of novel small molecules with broad 
therapeutic applications in neurology, diabetes and cardiology. The acquired assets include three oral, clinical stage drug candidates 
and a library of 500 small molecule drug candidates. The acquisition positions CytRx as a clinical-stage company with a Phase II trial 
for ALS with one of its new compounds, arimoclomol, expected to be initiated by the second quarter of 2005. 

To date, the Company has relied primarily upon selling equity securities and, to a lesser extent, upon payments from its strategic 
partners  and  licensees  to  generate  the  funds  needed  to  finance  its  operations.  Management  believes  the  Company’s  cash  and  cash 
equivalents balances will be sufficient to meet cash requirements into the second quarter of 2006. The Company will be required to 
obtain additional funding in order to execute its long-term business plans. The Company cannot assure that additional funding will be 
available on favorable terms, or at all. If the Company fails to obtain significant additional funding when needed, it may not be able to 
execute its business plans and its business may suffer, which would have a material adverse effect on its financial position, results of 
operations and cash flows. 

2.  Summary of Significant Accounting Policies 

Basis  of  Presentation  and  Principles  of  Consolidation  —  The  consolidated  financial  statements  include  the  accounts  of  CytRx 
together  with  those  of  its  majority-owned  subsidiaries.  The  accounts  of  the  Subsidiary  are  included  since  September  17,  2003  (see 
Note 11). The accounts of Global Genomics are included since July 19, 2002 (see Note 12). 

Revenue  Recognition  —  Service  revenues  relate  to  recruiting  services  rendered  and  are  recognized  at  the  time  services  are 
rendered because all obligations necessary to earn such revenues have been completed by the Company at that time. Revenues from 
collaborative research arrangements and grants are generally recorded as the related costs are incurred. The costs incurred under such 
arrangements  are  recorded  as  research  and  development  expense  and  approximate  the  revenues  reported  in  the  accompanying 
statements  of  operations.  Non-refundable  license  fee  revenue  is  recognized  when  collectibility  is  reasonably  assured,  which  is 
generally  upon  receipt, when  no  continuing  involvement  of  the  Company  is  required and  payment  of  the  license  fee  represents  the 
culmination of the earnings process. Non-refundable license fees received subject to future performance by the Company or that are 
credited  against  future  payments  due  to  the  Company  are  deferred  and  recognized  as  services  are  performed  and  collectibility  is 
reasonably  assured,  which  is  generally  upon  receipt,  or  recognized  upon  termination  of  the  agreement  and  all  related  obligations 
thereunder. 

Cash Equivalents — The Company considers all highly liquid debt instruments with an original maturity of 90 days or less to be 

cash equivalents. Cash equivalents consist primarily of amounts invested in money market accounts. 

Investments — Management determines the appropriate classification of debt securities at the time of purchase. Debt securities are 
classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity 
securities are stated at amortized cost. Marketable equity securities and debt securities not classified as held-to-maturity are classified 
as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported as a separate 
component of stockholders’ equity. Realized gains and losses are included in investment income and are determined on a first-in, first-
out basis. 

 
 
 
 
 
 
 
 
 
 
 
 
 
Fair Value of Financial Instruments — The carrying amounts reported in the balance sheet for cash and cash equivalents, short-

term investments, notes receivable and accounts payable approximate their fair values. 

Property and Equipment — Property and equipment are stated at cost and depreciated using the straight-line method based on the 
estimated useful lives (generally five years for equipment and furniture) of the related assets. Whenever there is a triggering event that 
might suggest an impairment, management evaluates the realizability of recorded long-lived assets to determine whether their carrying 
values  have  been  impaired.  The  Company  records  impairment  losses  on  long-lived  assets  used  in  operations  when  events  and 
circumstances indicate that the assets might be impaired and the nondiscounted cash flows estimated to be generated by those assets 
are  less  than  the  carrying  amount  of  those  assets.  Any  impairment  loss  is  measured  by  comparing  the  fair  value  of  the  asset  to  its 
carrying amount. 

Patents  and  Patent  Application  Costs  —  Although  the  Company  believes  that  its  patents  and  underlying  technology  have 
continuing value, the amount of future benefits to be derived therefrom is uncertain. Patent costs are therefore expensed rather than 
capitalized. 

Basic  and  Diluted  Loss  per  Common  Share  —  Basic  and  diluted  loss  per  common  share  are  computed  based  on  the  weighted 
average  number  of  common  shares  outstanding.  Common  share  equivalents  (which  consist  of  options,  warrants  and  convertible 
Subsidiary  common  stock)  are  excluded  from  the  computation  of  diluted  loss  per  share  since  the  effect  would  be  antidilutive. 
Common share equivalents which could potentially dilute basic earnings per share in the future, and which were excluded from the 
computation  of  diluted  loss  per  share,  totaled  approximately  14.5  million  shares,  10.1  million  shares  and  6.7  million  shares  at 
December 31, 2004, 2003 and 2002, respectively. 

Shares  Reserved  for  Future  Issuance  —  As  of  December  31,  2004,  the  Company  has  reserved  approximately  5,488,974  of  its 
authorized but unissued shares of common stock for future issuance pursuant to its employee stock option plans and warrants issued to 
consultants and investors. 

Stock-based Compensation — The Company grants stock options and warrants for a fixed number of shares to key employees and 
directors  with  an  exercise  price  equal  to  the  fair  market  value  of  the  shares  at  the  date  of  grant.  The  Company  accounts  for  stock 
option grants and warrants in accordance with Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to 
Employees (“APB 25”) and related interpretations, and, accordingly, recognizes no compensation expense for the stock option grants 
and  warrants  issued  to  employees  for  which  the  terms  are  fixed.  For  stock  option  grants  and  warrants  which  vest  based  on  certain 
corporate performance criteria, compensation expense is recognized to the extent that the quoted market price per share exceeds the 
exercise price on the date such criteria are achieved or are probable. Statement of Financial Accounting Standards (“SFAS”) No. 123, 
Accounting  for  Stock-based  Compensation  (“SFAS  123”),  provides  an  alternative  to  APB  25  in  accounting  for  stock-based 
compensation issued to employees. However, the Company has continued to account for stock-based compensation for employees in 
accordance with APB 25 (See Note 14). The Company has also granted stock options and warrants to certain consultants and other 
third parties. Stock options and warrants granted to consultants and other third parties are accounted for in accordance with SFAS 123 
and  related  interpretations  and  are  valued  at  the  fair  market  value  of  the  options  and  warrants  granted  or  the  services  received, 
whichever is more reliably measurable. Expense is recognized in the period in which a performance commitment exists or the period 
in which the services are received, whichever is earlier. 

SFAS  123,  as  amended  by  SFAS  No.  148,  Accounting  for  Stock-Based  Compensation  —  Transition  and  Disclosure  (“SFAS 
148”),  requires  the  presentation  of  pro  forma  information  as  if  the  Company  had  accounted  for  its  employee  stock  options  and 
performance awards under the fair value method of that statement. For purposes of pro forma disclosure, the estimated fair value of 
the  options  and  performance  awards  at  the  date  of  the  grant  is  amortized  to  expense  over  the  vesting  period.  The  following  table 
illustrates the effect on net loss and loss per share if the Company had applied the fair value recognition provisions of SFAS 123 to 
stock-based employee compensation (amounts in thousands except per share data):

The fair value for the Company’s options and warrants was estimated at the date of grant using a Black-Scholes option pricing 

model with the following assumptions: 

Weighted average risk free interest rate....................................................................................................
Dividend yields .........................................................................................................................................
Volatility factors of the expected market price of the Company’s common stock ...................................
Weighted average years outstanding.........................................................................................................

The  Black-Scholes  option  valuation  model  was  developed  for  use  in  estimating  the  fair  value  of  traded  options  which  have  no 
vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions 
including  the  expected  stock  price  volatility.  Because  the  Company’s  employee  stock  options  have  characteristics  significantly 
different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value 
estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its 
warrants and employee stock options. 

Research and Development Expenses —  Research  and development  expenses  consist of costs  incurred for direct  and  overhead-
related research expenses and are expensed as incurred. Costs to acquire technologies which are utilized in research and development 
and which have no alternative future use are expensed when incurred. Technology developed for use in our products is expensed as 
incurred until technological feasibility has been established. Expenditures to date have been classified as research and development 
expense. 

Income Taxes — Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax 
assets  and  liabilities  for  the  expected  future  tax  consequences  of  events  that  have  been  recognized  in  the  Company’s  financial 
statements or tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will 
more than likely not be realized. 

Concentrations of Credit Risk — Financial instruments that potentially subject the Company to significant concentrations of credit 
risk consist principally of cash and cash equivalents, short-term investments and note receivable. The Company maintains cash and 
cash equivalents in large well-capitalized financial institutions and the Company’s investment policy disallows investment in any debt 
securities rated less than “investment-grade” by national ratings services. The Company has not experienced any losses on its deposits 
of  cash  and  cash  equivalents.  The  Company  is  at  risk  to  the  extent  accounts  receivable  and  note  receivable  amounts  become 
uncollectible. 

Use of Estimates — The preparation of the financial statements in conformity with accounting principles generally accepted in the 
United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial 
statements and accompanying notes. Actual results could differ materially from those estimates. 

Segment Information — Management uses consolidated financial information in determining how to allocate resources and assess 

financial performance. For this reason, the Company has determined that it is principally engaged in one industry segment. 

3.  Recent Accounting Pronouncements 

Recently  Issued  Accounting  Standards  —  In  December  2004,  the  Financial  Accounting  Standards  Board  (“FASB”)  revised  and 
issued SFAS 123, Share-Based Payment (SFAS 123(R)). SFAS 123(R) eliminates the alternative of using the APB 25 intrinsic value 
method of accounting for stock options. This revised statement will require recognition of the cost of employee services received in 
exchange for awards of equity instruments based on the fair value of the award at the grant date. This cost is required to be recognized 
over the vesting period of the award. The stock-based compensation table in Note 2 illustrates the effect on net income and earnings 
per share if we had applied the fair value recognition provisions of SFAS 123 to stock-based employee compensation. SFAS 123(R) 
applies  to  all  awards granted,  modified,  repurchased, or  cancelled  after  June  30, 2005. We  will  early-adopt  SFAS 123(R)  effective 
January 1, 2005, using the modified prospective method. As a result of the adoption of this statement, our compensation expense for 
share-based payments is expected to be approximately $1.5 million in 2005. 

 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
4.  Investments 

At  December  31,  2004  the  Company  held  approximately  $1.0  million  in  short-term  investments.  At  December  31,  2003  the 
Company did not have any investments. The contractual maturities of securities held at December 31, 2004 were one year or less. At 
December 31, 2004, the Company classified all of its investments (consisting entirely of Certificates of Deposit) as held-to-maturity. 
The fair market value approximated the carrying costs and gross unrealized and realized gains/losses were immaterial. 

5.  Restricted Assets 

At December 31, 2004 and 2003, the Company held approximately $51,000 and $50,000, respectively, in investments (consisting 
entirely of Certificates of Deposit), reported in Prepaid and Other Current Assets in the accompanying consolidated balance sheets. 
The  contractual  maturities  of  securities  held  at  December  31,  2004  were  one  year  or  less.  At  December  31,  2004  and  2003,  the 
investments were pledged as collateral for a letter of credit for the same amount issued in connection with one of the Company’s lease 
agreements. 

6.  Property and Equipment 

Property and equipment at December 31 consist of the following (in thousands): 

Equipment and furnishings .........................................................................................................................................

At December 31, 2004, the molecular library had been purchased, but had not been placed in service by the Company, because the 

compounds had not been physically received. Therefore, no amortization of the related patents was recorded in fiscal 2004. 

Asset  Impairment  Loss  —  In  May  2002,  Organichem,  Corp.,  which  was  to  provide  CytRx  with  commercial  supplies  of  Flocor 
purified drug substance, advised CytRx that it did not intend to renew the Company’s agreement when it expired in December 2003. 
During the fourth quarter of 2002, the Company determined that, in light of the relatively short remaining term of the Organichem 
contract, the significant costs that would be associated with relocating the equipment owned by CytRx in connection with this contract 
and the Company’s lack of success to date in its continuing search for a strategic partner for the development of Flocor, an impairment 
loss  of  approximately  $921,000  should  be  recorded,  which  equals  the  then  net  book  value  of  this  equipment  and  related  leasehold 
improvements. This charge is reflected as a separate line item in the accompanying consolidated statement of operations for the year 
ended December 31, 2002 as an asset impairment charge. 

7.  Accrued Expenses

8.  Facility Abandonment 

In the fourth quarter of 2002, the Company recorded a loss of approximately $478,000 associated with the closure of its Atlanta 
headquarters and relocation to Los Angeles subsequent to its  merger with Global Genomics (see Note 12). This loss represents the 
total  remaining  lease  obligations  and  estimated  operating  costs  through  the  remainder  of  the  lease  term,  less  estimated  sublease 
income  and  is  reflected  in  Note  9  —  Commitments  and  Contingencies.  This  accrued  charge  was  combined  with  deferred  rent  of 
$85,000 already recorded, so that the total accrual related to the facility abandonment was $563,000 as of December 31, 2002. As of 
December 31, 2004 and 2003, the accrued loss on facility abandonment was $312,000, $105,000 of which was reflected as a current 
liability and $207,000 as a non-current liability. As of December 31, 2003, the accrued loss on facility abandonment was $418,000, 
$106,000 of which was  reflected  as  a  current  liability  and  $312,000  as  a  non-current  liability.  During  2004,  the  Company  incurred 
expenditures  totaling  $210,000  for  the  abandoned  facility  and  utilized  $106,000  of  the  accrual  related  to  the  facility  abandonment. 
During 2003, the Company incurred expenditures totaling $224,000 for the abandoned facility and utilized $145,000 of the accrual 
related to the facility abandonment.

Under  the  various  license  agreements  and  sponsored  research  agreements  with  University  of  Massachusetts  Medical  School 
(“UMMS”)  (see  Note  17)  and  other  institutions,  CytRx  will  be  required  to  make  annual  license  maintenance  payments  as  well  as 
milestone payments, ranging from $11 million to $14 million per approved product, to UMMS and/or other institutions based on the 
development  of  products  utilizing  the  licensed  technology  and  will  be  required  to  pay  royalties,  based  on  future  sales  of  those 
products, which will generally range from 3% to 7.5% of such sales, depending upon the product and the technology being utilized. In 
connection  with  the  sponsored  research  agreements,  CytRx  agreed  to  fund  certain  pre-clinical  research  at  UMMS  and  other 
institutions related to the use of CytRx’s licensed technologies for the development of therapeutic products. 

The  Company  has  employment  agreements  with  its  executive  officers,  the  terms  of  which  expire  at  various  times  through  July 
2006. Certain agreements, which have been revised from time to time, provide for minimum salary levels, adjusted annually at the 
Compensation  Committee’s  determination,  as  well  as  for  minimum  bonuses  that  are  payable.  The  reported  commitment  for 
employment  agreements  includes,  among  other  things,  a  total  of  $1.0  million  of  compensation  payable  to  members  of  CytRx’s 
Scientific Advisory Board, and a total of $1.2 million of salary and guaranteed bonuses payable to CytRx’s executives. 

Rent  expense  under  operating  leases  during  2004,  2003  and  2002  was  approximately  $260,000,  $258,000  and  $171,000, 

respectively. 

10.  Private Placements of Common Stock 

In  October  2004,  the  Company  entered  into  a  Stock  Purchase  Agreement  with  a  group  of  institutional  and  other  investors  (the 
“October 2004 Investors”). The October 2004 Investors purchased, for an aggregate purchase price of $4.0 million, 4,000,000 shares 
of the Company’s common stock and warrants to purchase an additional 3,080,000 shares of the Company’s common stock, at $1.69 
per share, expiring in 2009. After consideration of offering expenses, net proceeds to the Company were approximately $3.7 million. 
The shares and the shares underlying the warrants issued to the October 2004 Investors were subsequently registered. In addition, the 
Company issued approximately $204,000 worth of common stock in January 2004. 

 
 
 
 
 
 
  
  
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
   
   
 
 
 
 
 
 
 
In September 2003, the Company entered into a Stock Purchase Agreement with a group of institutional and other investors (the 
“September 2003 Investors”). The September 2003 Investors purchased, for an aggregate purchase price of $8.7 million , 4,140,486 
shares of the Company’s common stock and warrants to purchase an additional 1,035,125 shares of the Company’s common stock, at 
$3.05 per share, expiring in 2008. After consideration of offering expenses, net proceeds to the Company were approximately $7.7 
million. The shares and the shares underlying the warrants issued to the September 2003 Investors were subsequently registered. 

In  May  2003,  the  Company  entered  into  a  Stock  Purchase  Agreement  with  a  group  of  institutional  investors  (the  “May  2003 
Investors”). The May 2003 Investors purchased, for an aggregate purchase price of $5.4 million , 2,940,539 shares of the Company’s 
common stock and warrants to purchase an additional 735,136 shares of the Company’s common stock, at $3.05 per share, expiring in 
2008. After  consideration  of offering  expenses, net  proceeds  to  the  Company were  approximately  $4.8  million.  The  shares  and  the 
shares underlying the warrants issued to the May 2003 Investors were subsequently registered. 

11.  Investment in Subsidiary 

On  September  17,  2003,  CytRx  purchased  2,000  shares  of  convertible  preferred  stock  for  $7  million,  representing  a  95% 
ownership interest in the Subsidiary. The Subsidiary is a newly formed entity that plans to develop orally active small molecule based 
drugs  to  prevent,  treat  and  cure  obesity  and  type  2  diabetes.  This  funding  was  provided  out  of  the  proceeds  of  CytRx’s  private 
placement financing that was completed in September 2003. Since September 17, 2003, CytRx has consolidated the Subsidiary, based 
on CytRx’s ability to control the stockholders’ votes and the Board of Directors of the Subsidiary, and recorded a minority interest 
liability of $350,000, representing the 5% interest in the Subsidiary held by Dr. Michael Czech (see Note 19). Prior to September 17, 
2003, the Subsidiary had no operations. Additionally, the Company has recorded the fair value of 300,000 shares of its common stock 
as additional paid-in capital for the Company’s right to call and Dr. Czech’s right to put his remaining 5% interest in the Subsidiary to 
CytRx in exchange for a guaranteed amount of 300,000 shares of CytRx common stock. The fair value of these shares on the purchase 
date  was  approximately  $723,000.  In  addition,  upon  the  occurrence  of  certain  events,  Dr.  Czech  may  receive  up  to  an  additional 
350,000 shares of CytRx common stock. 

In  connection  with  the  investment  in  the  Subsidiary,  CytRx  acquired  the  rights  to  certain  in-process  research  and  development 
related to obesity and type 2 diabetes, which was owned by Dr. Czech. Because the in-process research and development acquired was 
not yet technologically feasible, CytRx recorded research and development expense of $1,073,000. 

12.  Merger with Global Genomics 

On February 11, 2002, CytRx entered into an agreement to acquire Global Genomics, a privately-held genomics holding company, 
through a merger of GGC Merger Corporation, a wholly-owned subsidiary of CytRx, into Global Genomics. Global Genomics is a 
genomics  holding  company  that  currently  has  a  40%  ownership  interest  in  Blizzard  and  a  5%  ownership  interest  in  Psynomics. 
CytRx’s  primary  reasons  for  the  acquisition  were  to  (a)  expand  its  business  into  the  genomics  field  to  diversify  its  product  and 
technology  base,  and (b) gain  the  management  and directors  of Global Genomics,  who  could  assist CytRx  in  developing  corporate 
partnerships and acquisition, investment and financing opportunities not previously available to CytRx. 

The transaction closed on July 19, 2002, after approval by the stockholders of each company and satisfaction of other customary 
closing conditions. Pursuant to the merger agreement, each outstanding share of common stock of Global Genomics was converted 
into  .765967  shares  of  the  Company’s  common  stock.  The  merger  resulted  in  the  issuance  of  8,948,204  shares  of  the  Company’s 
common stock and options and warrants to purchase 1,014,677 shares of the Company’s common stock to the former security holders 
of Global Genomics, with 498,144 shares of the Company’s common stock being held in escrow and subject to cancellation in whole 
or in part to satisfy any indemnification claims made by the Company under the merger agreement. These shares were released from 
escrow in 2003. CytRx issued an additional 548,330 shares of its Common Stock for investment banking and legal fees as part of the 
merger. 

The  merger  was  accounted  for  as  a  purchase  by  CytRx  of  a  group  of  assets  of  Global  Genomics  in  a  transaction  other  than  a 
business  combination  and  was  not  considered  to  be  a  reverse  acquisition.  The  Company  considered  the  provisions  of  Statement  of 
Financial  Accounting  Standards  No.  141,  Business  Combinations  (“SFAS  141”)  and  determined  CytRx  to  be  the  acquiror  for 
accounting purposes. Because the current activities of Global Genomics were focused on the development of a business rather than the 
operation  of  a  business  and  planned  principal  operations  of  Global  Genomics  had  not  yet  commenced,  Global  Genomics  was 
considered a development-stage company. Therefore, in accordance with the guidance in Emerging Issues Task Force Issue No. 98-3 
(“EITF 98-3”), “Determining Whether a Nonmonetary Transaction Involves Receipt of Productive Assets or of a Business,” Global 
Genomics did not constitute a business as defined in SFAS 141. Therefore, the Company allocated the purchase price in accordance 

 
 
 
 
 
 
 
 
 
 
with  the provisions of  Statement  of  Financial  Accounting  Standards  No. 142,  Goodwill  and Other  Intangible  Assets  (“SFAS 142”) 
related to the purchase of a group of assets. SFAS 142 provides that the cost of a group of assets acquired in a transaction other than a 
business combination shall be allocated to the individual assets acquired based on their relative fair values and shall not give rise to 
goodwill. 

The purchase price was determined in accordance with SFAS 141 and SFAS 142. A summary of the determination of the purchase 

price is as follows: 

Issuance of 8,948,204 shares of CytRx common stock at $0.6475 per share ......................................................................
Fair value of 1,014,677 vested warrants issued to purchase CytRx common stock.............................................................
Transaction costs..................................................................................................................................................................
Total purchase price.............................................................................................................................................................

$  5,793,962

$  7,364,490 

Since Global Genomics was a development-stage company and no goodwill can arise from the purchase of a development-stage 
company,  in  accordance  with  the  provisions  of  SFAS  141  and  SFAS  142,  all  identifiable  assets  acquired,  including  identifiable 
intangible assets, were assigned a portion of the purchase price on the basis of their relative fair values. To this end, an independent 
appraisal of Global Genomics’ assets was used as an aid in determining the fair value of the identifiable assets, including identified 
intangible assets, in allocating the purchase price among the acquired assets. 

Global Genomics’ primary assets were its investments in Blizzard and Psynomics and thus, the fair value of each of these entities 
was determined. The discounted cash flow approach was used to determine the estimated fair value of the acquired intangible assets of 
Blizzard  and  Psynomics  underlying  Global  Genomics’  investment  in  each  company.  Cash  flows  were  projected  for  a  period  of  10 
years and were discounted to net present value using discount factors of 46% to 60%. Material cash inflows from product sales were 
projected to begin in 2003 for Blizzard. A summary of the purchase price allocation is as follows: 

Current assets.....................................................................................................................................................................
Investment in minority-owned entity — acquired developed technology .........................................................................
In-process research and development (recognized as an expense) ....................................................................................
Less: Liabilities assumed ...................................................................................................................................................

The  in-process  research  and  development  was  recorded  as  a  charge  for  acquired  incomplete  research  and  development  in  the 
accompanying consolidated statement of operations and relates primarily to Global Genomics’ investment in Psynomics. The acquired 
developed technology primarily represents values assigned to Global Genomics’ investment in Blizzard’s DNA chip reader, thermal 
gradient station and T-Chips. The acquired technology was being amortized over a period of ten years until 2003, when CytRx wrote 
off its investment in Blizzard. The ten-year amortization period was determined through consideration of relevant patent terms (legal 
life), estimated technological and economic life, and the range of useful lives observed in public filings of other companies involved in 
similar DNA technologies. 

Equity in Losses of Blizzard.  The Company recorded its portion of the losses of Blizzard using the equity method. The equity in 
losses of Blizzard and the amortization of the acquired developed technology are reported as a separate line item in the accompanying 
consolidated statement of operations. 

Impairment  Test  of  Intangible  Assets.    In  accordance  with  the  provisions  of  Accounting  Principles  Board  Opinion  No.  18,  The 
Equity Method of Accounting for Investments in Common Stock (“APB 18”), the Company reviewed the net values on its balance 
sheet as of September 30, 2003 assigned to Investment in Minority — Owned Entity — Acquired Developed Technology resulting 
from  its  acquisition  of  Global  Genomics.  APB  18  requires  that  a  loss  in  value  of  an  investment,  which  is  other  than  a  temporary 
decline, should be recognized as an impairment loss. Through the third quarter of 2003, Blizzard had been unsuccessful in its attempts 
to raise a significant amount of the financing necessary for it to pursue the commercialization strategy for its products. 

CytRx’s analysis consisted of a review of current financial projections prepared by Blizzard, application of a discounted cash flow 
valuation  model  of  Blizzard’s  projected  cash  flows,  and  consideration  of  other  qualitative  factors.  Based  upon  the  quantitative  and 
qualitative factors described above and in addition to others, CytRx’s management determined that the estimated fair value of CytRx’s 
investment in Blizzard was $0 and that an impairment charge of $5,868,000 was necessary in 2003. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
As of December 31, 2003, the following assets related to Blizzard were reflected in CytRx’s balance sheets: 

Investment in minority owned entity — acquired developed technology.........................................................................
Receivable from Blizzard .................................................................................................................................................
Less: Accumulated amortization.......................................................................................................................................

In addition, $16,640 of receivable from Blizzard was recorded in prepaid and other current assets as of December 31, 2002. 

13.  Severance Payments to Officers 

In accordance with a Mutual General Release and Severance Agreement in May 2004, the Company agreed to pay the Company’s 
former  General  Counsel,  approximately  $87,500  and  12  months  of  related  benefits,  and  agreed  to  immediately  vest  options  to 
purchase  87,500  shares  of  its  common  stock  that  were  granted  upon  the  commencement  of  his  employment.  In  accordance  with  a 
Mutual General Release and Severance Agreement in May 2004, the Company agreed to pay the Company’s former Chief Financial 
Officer,  approximately  $150,000  and  18  months  of  related  benefits,  and  agreed  to  immediately  vest  options  to  purchase  105,000 
shares of its common stock that were granted upon the commencement of his employment. 

Pursuant  to  his  employment  agreement,  CytRx’s  former  President  and  CEO  (“Former  CEO”)  was  entitled  to  a  payment  of 
$435,150 upon the execution of the merger agreement between CytRx and Global Genomics (see Note 11) and an additional $435,150 
upon  the  closing  of  the  merger.  In  order  to  reduce  the  amount  of  cash  that  CytRx  had  to  pay  to  the  Former  CEO,  CytRx  and  the 
Former CEO agreed that approximately $325,200 of the first $435,150 payment would be satisfied by CytRx granting a stock award to 
the Former CEO under the CytRx Corporation 2000 Long-Term Incentive Plan under which CytRx issued the Former CEO 558,060 
shares of the Company’s common stock. Those shares of stock were issued at a value equal to 85% of the volume weighted average 
price of CytRx common stock for the 20 trading days ended on February 8, 2002. The cash payment and fair value of the shares issued 
were recognized as expense during the first quarter of 2002. 

The terms of CytRx’s merger with Global Genomics contemplated that Global Genomics’ management team would replace that of 
CytRx’s  subsequent  to  the  closing  of  the  merger.  On  July  16,  2002,  CytRx  terminated  the  employment  of  all  of  its  then-current 
officers,  resulting  in  total  obligations  for  severance,  stay  bonuses,  accrued  vacation  and  other  contractual  payments  of  $1,394,000 
(including the final $435,150 owed to the Former CEO). Prior to the merger closing date, CytRx advanced part of these amounts to 
three  of  its  officers,  such  that  the  total  remaining  obligation  at  the  closing  date  was  $1,179,000.  Four  officers  agreed  to  accept  an 
aggregate total of $177,000 of such amount in the form of the Company’s common stock, in lieu of cash, resulting in the issuance of 
248,799 shares. Thus, the net cash payout in satisfaction of these obligations was $1,002,000, before taxes. The severance payments 
and fair value of the shares issued were recognized as expense during the third quarter of 2002 and is reported as a separate line item 
on  the  accompanying  consolidated  statement  of  operations  together  with  the  cash  payment  and  fair  value  of  shares  issued  to  the 
Former CEO discussed above. 

14.  Stock Options and Warrants 

CytRx has stock option plans pursuant to which certain key employees, directors and consultants are eligible to receive incentive 
and/or  nonqualified  stock  options  to  purchase  shares  of  CytRx’s  common  stock.  Fixed  options  granted  under  the  plans  generally 
become exercisable over a three-year period from the dates of grant and have lives of ten years. The Company may also grant stock 
options  and/or  warrants  to  its  Chief  Executive  Officer  and  other  executive  officers  containing  alternative  or  additional  vesting 
provisions  based  on  the  achievement  of  corporate  objectives.  Exercise  prices  of  all  stock  options  and  warrants  for  employees  and 
directors are set at the fair market values of the common stock on the dates of grant. 

In  connection  with  the  Company’s  private  equity  financing  that  was  consummated  on  October  4,  2004,  the  Company  repriced 
warrants to purchase approximately 2.8 million shares of its common stock, as a result of anti-dilution provisions in those warrants 
that were triggered by the Company’s issuance of common stock in that equity financing at a price below the closing market price on 
the date of the transaction. As a result of the modification, these warrants are required to be accounted for as variable options under 
APB  25  and  related  Interpretations.  Pursuant  to  the  anti-dilution  provision,  the  exercise  price  of  those  warrants  was  reduced  from 
between  $1.85  and  $3.05  per  share,  to  between  $1.78  and  $2.94  per  share,  and  the  number  of  shares  underlying  the  warrants  was 
increased to approximately 2.9 million. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In connection with the Company’s acquisition of Global Genomics in July 2002 (see Note 12), CytRx issued 1,014,677 warrants to 
the holders of Global Genomics warrants in return for the cancellation of all of their outstanding Global Genomics warrants. The new 
warrants  were  100%  vested  upon  their  issuance,  have  an  exercise  price  of  $0.01  per  share  and  expire  on  January  31,  2007. 
Additionally,  the  acquisition  of  Global  Genomics  triggered  the  “Change  of  Control”  provisions  contained  in  the  Company’s  stock 
option plans and in the warrants held by the Company’s Former CEO, resulting in the immediate vesting of all outstanding warrants 
held by the Former CEO and of all outstanding stock options issued pursuant to the Company’s various stock options plans. 

During  2004,  2003  and  2002,  services  were  received  in  exchange  for  stock  options  and  warrants  issued  to  certain  consultants, 

resulting in aggregate non-cash charges of $1.1 million, $1.6 million and $230,000, respectively.

15.  Stockholder Protection Rights Plan 

Effective April 16, 1997, the Company’s Board of Directors declared a distribution of one right (“Rights”) for each outstanding 
share  of  the  Company’s  common  stock  to  stockholders  of  record  at  the  close  of  business  on  May  15,  1997  and  for  each  share  of 
common  stock  issued  by  the  Company  thereafter  and  prior  to  a  Flip-in  Date  (as  defined  below).  Each  Right  entitles  the  registered 
holder to purchase from the Company one-ten thousandth (1/10,000th) of a share of Series A Junior Participating Preferred Stock, at 
an exercise price of $30. The Rights are generally not exercisable until 10 business days after an announcement by the Company that a 
person or group of affiliated persons (an “Acquiring Person”) has acquired beneficial ownership of 15% or more of the Company’s 
then  outstanding  shares  of  common  stock  (a  “Flip-in  Date”).  In  connection  with  the  merger  agreement  with  Global  Genomics,  the 
Company’s Board of Directors amended the stockholders protection rights agreement to exempt the merger from triggering a Flip-in 
Date. 

In the event the Rights become exercisable as a result of the acquisition of shares, each Right will enable the owner, other than the 
Acquiring  Person,  to  purchase  at  the  Right’s  then-current  exercise  price  a  number  of  shares  of  common  stock  with  a  market  value 
equal to twice the exercise price. In addition, unless the Acquiring Person owns more than 50% of the outstanding shares of common 
stock, the Board of Directors may elect to exchange all outstanding Rights (other than those owned by such Acquiring Person) at an 

 
 
 
 
 
 
  
  
  
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
  
  
 
 
 
 
 
  
  
  
  
  
 
 
 
 
  
  
 
  
 
 
  
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
exchange ratio of one share of common stock per Right. All Rights that are owned by any person on or after the date such person 
becomes an Acquiring Person will be null and void. 

The Rights have been distributed to protect the Company’s stockholders from coercive or abusive takeover tactics and to give the 

Board of Directors more negotiating leverage in dealing with prospective acquirors. 

16.  Income Taxes 

For  income  tax  purposes,  CytRx  and  its  subsidiaries  have  an  aggregate  of  approximately  $79.6  million  of  net  operating  losses 
available  to  offset  against  future  taxable  income,  subject  to  certain  limitations.  Such  losses  expire  in  2005  through  2023  as  of 
December 31, 2004. CytRx also has an aggregate of approximately $6.3 million of research and development and orphan drug credits 
available for offset against future income taxes that expire in 2005 through 2021. 

Deferred income taxes reflect the net effect of temporary differences between the financial reporting carrying amounts of assets 
and liabilities and income tax carrying amounts of assets and liabilities. The components of the Company’s deferred tax assets and 
liabilities, all of which are long-term, are as follows (in thousands):

Based on assessments of all available evidence as of December 31, 2004 and 2003, management has concluded that the respective 
deferred income tax assets should be reduced by valuation allowances equal to the amounts of the net deferred income tax assets since 
it is management’s conclusion that it is more likely than not that the deferred tax assets will not be realized. Furthermore, it is likely 
the July 19, 2002 acquisition of Global Genomics caused a change of ownership as defined by Internal Revenue Code Section 382 
which may substantially limit the ability of the Company to utilize net operating losses incurred prior to that date. Generally, the net 
operating losses will be limited to an annual utilization of approximately 4.9% of the purchase price of Global Genomics. 

For all years presented, the Company did not recognize any deferred tax assets or liabilities and deferred tax provision or benefit. 

The  provision  for  income  taxes  differs  from  the  provision  computed  by  applying  the  Federal  statutory  rate  to  net  loss  before 

income taxes as follows (in thousands):

17.  License Agreements 

University  of  Massachusetts  Medical  School  —  In  April  2003,  CytRx  acquired  the  rights  to  new  technologies  by  entering  into 
exclusive license arrangements with the UMMS covering potential applications of the medical institution’s proprietary gene silencing 
technology  in the  treatment  of  specified diseases,  including  those within  the  areas of obesity  and  type 2 diabetes, and  amyotrophic 
lateral  sclerosis,  commonly  known  as  Lou  Gehrig’s  disease  (ALS),  human  cytomegalovirus,  and  covering  UMMS’s  proprietary 
technology  with  potential  gene  therapy  applications  within  the  area  of  cancer.  In  consideration  of  the  licenses,  CytRx  made  cash 
payments to UMMS totaling approximately $186,000 and issued it a total of 1,613,258 shares of CytRx common stock, which were 

 
 
 
 
 
 
 
  
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
valued  for  financial  statement  purposes  at  approximately  $1,468,000.  In  May  2003,  CytRx  broadened  its  strategic  alliance  with 
UMMS  by  acquiring  an  exclusive  license  from  that  institution  covering  a  proprietary  DNA-based  HIV  vaccine  technology.  In 
consideration of this license, CytRx made cash payments to UMMS totaling approximately $18,000 and issued it 215,101 shares of 
CytRx common stock, which were valued for financial statement purposes at approximately $361,000. In July 2004, CytRx further 
expanded its strategic alliance with UMMS by entering into a collaboration and invention disclosure agreement with UMMS under 
which UMMS  will  disclose  to  CytRx  certain new  technologies developed  at  UMMS  over  the next  three  years pertaining  to  RNAi, 
diabetes,  obesity,  neurodegenerative  diseases  (including  ALS)  and  CMV  and  will  give  CytRx  an  option,  upon  making  a  specified 
payment,  to  negotiate  an  exclusive  worldwide  license  to  the  disclosed  technologies  on  commercially  reasonable  terms.  As  of 
December  31,  2004,  CytRx  had  made  cash  payments  to  UMMS  totaling  $187,500  pursuant  to  the  collaboration  agreement  with 
UMMS, but has not yet acquired or made any payments to acquire any options under that agreement. 

In May 2004, CytRx licensed from the technology transfer company of the Imperial College of Science, Technology & Medicine, 
or Imperial College, the exclusive rights to intellectual property covering a drug screening method using RIP 140, which is a nuclear 
hormone  co-repressor  that  is  believed  to  regulate  fat  accumulation.  In  consideration  of  the  license,  CytRx  made  cash  payments  to 
Imperial  College  totaling  $87,000  and  issued  it  a  total  of  75,000  shares  of  CytRx  common  stock  which  were  valued,  for  financial 
statement purposes, at $108,000. As the drug screening technology from Imperial College and the RNAi technology from UMMS had 
not achieved technological feasibility at the time of their license by CytRx, had no alternative future uses and, therefore, no separate 
economic value, the total value of all cash payments and stock issued for acquisition of the technology was expensed as research and 
development in our financial statements.

19.  Related Party Transactions 

In July 2002, the Company entered into an agreement with Kriegsman Capital Group (“KCG”), whereby KCG or its affiliate The 
Kriegsman Group (“TKG”) agreed to provide CytRx with office space and certain administrative services. KCG and TKG are owned 
by Steven A. Kriegsman, CytRx’s President and CEO. During the years ended December 31, 2003 and 2002, the Company made net 
payments of $70,000 and $59,000, respectively, to KCG under this agreement. The charges were determined based upon actual space 
used and estimated percentages of employee time used. The Company believes that such charges approximated the fair value of the 
space and services provided. In October 2003, the services and facilities agreement with KCG was terminated as substantially all of 
the on-going operations of KCG have ceased. The obligations under the facility lease at the Company’s headquarters were transferred 
from KCG to CytRx in July 2003 and are reflected in Note 9 — Commitments and Contingencies. 

Dr.  Michael  Czech,  a  5%  minority  stockholder  of  the  Subsidiary  (see  Note  11) and  a  member  of  CytRx’s  and  the  Subsidiary’s 
Scientific  Advisory  Boards,  is  an  employee  of  UMMS  and  party,  as  the  principal  investigator,  to  a  sponsored  research  agreement 
between  CytRx  and  UMMS.  The  Company  recorded  a  minority  interest  liability  of  $350,050,  representing  the  5%  interest  in  the 
Subsidiary held by Dr. Czech. Additionally, the Company recorded the fair value of 300,000 shares of its common stock as additional 
paid-in capital for the Company’s right to call and Dr. Czech’s right to put the remaining 5% interest in the Subsidiary to CytRx in 

 
 
 
 
 
 
  
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
exchange for a guaranteed amount of 300,000 shares of CytRx common stock. The fair value of these shares on the purchase date was 
approximately $723,000. During 2003, Dr. Czech was paid $18,000 for his Scientific Advisory Board services. In addition, upon the 
occurrence of certain events, Dr. Czech may receive up to an additional 350,000 shares of CytRx common stock. During 2004 and 
2003,  CytRx  paid  UMMS  $806,000  and  $403,000,  respectively,  under  the  sponsored  research  agreement  to  fund  a  portion  of  Dr. 
Czech’s research. 

20.  Subsequent Event 

On January 20, 2005, the Company completed a $21.3 million private equity financing in which we issued 17,334,494 shares of 
our common stock and warrants to purchase an additional 8,667,247 shares of our common stock at an exercise price of $2.00 per 
share. Net of investment banking commissions, legal, accounting and other fees related to the transaction, we received proceeds of 
approximately $19.5 million. The following selected pro forma balance sheet data is derived from our balance sheet as of December 
31, 2004 and gives effect to the completion of that private equity financing, but does not give effect to other events that occurred since 
December 31, 2004 and thus may not be indicative of our current financial condition. The information should be read in conjunction 
with our balance sheet as of December 31, 2004 and related notes.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Stockholders and Board of Directors 
CytRx Corporation 
Los Angeles, California 

We have audited the accompanying consolidated balance sheets of CytRx Corporation and subsidiaries as of December 31, 2004 
and 2003 and the related consolidated statements of operations, stockholders’ equity and cash flows for the years then ended. We have 
also  audited  the  schedule  listed  in  the  accompanying  index.  These  financial  statements  and  schedule  are  the  responsibility  of  the 
Company’s management. Our responsibility is to express an opinion on the 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. The Company is not required to have, nor were we engaged to perform, an audit of its internal control 
over  financial  reporting.  Our  audit  included  consideration  of  internal  control  over  financial  reporting  as  a  basis  for  designing  audit 
procedures  that  are  appropriate  in  the  circumstances,  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the 
Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a 
test basis, evidence supporting the amounts and disclosures in the financial statements, and 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 consolidated financial statements referred to above present fairly, in all material respects, the financial position 
of CytRx Corporation and subsidiaries at December 31, 2004 and 2003 and the results of their operations and their cash flows for the 
years then ended, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, 
the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly 
in all material respects the information set forth therein.

15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States).

In  our  opinion,  the  consolidated  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  consolidated
