“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, or SEC, in its 
rules, regulations and releases, including Section 27A of the Securities Act of 1933, as amended 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, 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 
statement of assumptions underlying any of the foregoing. In some cases, forward-looking statements can be identified by the use of 
terminology  such  as  “may,”  “will,”  “expects,”  “plans,”  “anticipates,”  “estimates,”  “potential”  or  “could”  or  the  negative  thereof  or 
other comparable terminology. Although we believe that the expectations reflected in the forward-looking statements contained herein 
and in documents incorporated by this Annual Report are reasonable, there can be no assurance that such expectations or any of the 
forward-looking statements will prove to be correct, and actual results could differ materially from those projected or assumed in the 
forward-looking statements. 

Our future financial condition and results of operations, as well as any forward-looking statements, are subject to inherent risks 
and uncertainties, including but not limited to the risk factors set forth under the heading “Risk Factors” in this Annual Report, and

PART I 

As  used  in  this  report,  the  terms  “we,”  “our,”  “ours”  and  “us”  refer  to  CytRx  Corporation,  a  Delaware  corporation,  unless  the 

context suggests otherwise. 

General 

We  are  a  biopharmaceutical  research  and  development  company,  based  in  Los  Angeles,  California,  with  an  obesity  and  type  2 
diabetes research laboratory 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. Our small molecule therapeutics 
efforts  include  our  clinical  development  of  three  oral  drug  candidates  that  we  acquired  in  October  2004,  including  a  Phase  II  trial 
initiated  in  September  2005,  as  well  as  our  drug  discovery  operations  conducted  at  our  laboratory  in  Worcester,  Massachusetts. 
Development work on RNAi, a relatively recent technology for silencing genes in living cells and organisms, is still at an early stage, 
and  we  are  aware  of  only  four  clinical  tests  of  therapeutic  applications  using  RNAi  that  have  yet  been  initiated  by  any  party.  In 
addition  to  our  work  in  RNAi  and  small  molecule  therapeutics,  we  recently  announced  that  a  novel  HIV  DNA  +  protein  vaccine 
exclusively licensed to us and developed by researchers at the University of Massachusetts Medical School, or UMMS, and Advanced 
BioScience Laboratories, and funded by the National Institutes of Health, demonstrated promising interim Phase I clinical trial results 
that indicate its potential to produce potent antibody responses with neutralizing activity against multiple HIV viral strains. We have 
also entered into strategic alliances with respect to the development of several other products using our other technologies. 

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 based on molecular 
“chaperone”  co-induction  technology,  with  broad  therapeutic  applications  in  neurology,  type  2  diabetes,  cardiology  and  diabetic 
complications.  The  acquired  assets  include  three  oral,  clinical  stage  drug  candidates  and  a  library  of  500  small  molecule  drug 
candidates. We recently entered the clinical stage of drug development with the initiation of a Phase II clinical program with our lead 
small  molecule  product  candidate  arimoclomol  for  the  treatment  of  amyotrophic  lateral  sclerosis  (ALS  or  Lou  Gehrig’s  disease). 
Arimoclomol has received Orphan Drug and Fast Track designation from the U.S. Food and Drug Administration. 

The  initial  Phase  II  clinical  trial  that  we  have  initiated  for  arimoclomol  for  ALS  (which  we  refer  to  as  the  Phase  IIa  trial)  is  a 
multicenter, double-blind, placebo-controlled study of approximately 80 ALS patients enrolled at ten clinical centers across the U.S. 
Patients  enrolled  in  Phase IIa  trial  will  receive  either placebo (a  capsule  without  drug), or one of  three  dose  levels  of  arimoclomol 
capsules  three  times  daily,  for  a  period  of  12  weeks.  This  treatment  phase  will  be  immediately  followed  by  a  one-month  period 
without  drug.  The  primary  endpoints  of  this  Phase  IIa  trial  are  safety  and  tolerability.  Secondary  endpoints  include  a  preliminary 
evaluation of efficacy using two widely accepted surrogate markers, the revised ALS Functional Rating Scale (ALSFRS-R), which is 
used  to  determine  patients’  capacity  and  independence  in  13  functional  activities,  and  Vital  Capacity  (VC),  an  assessment  of  lung 
capacity.  The  trial  is  powered  to  monitor  only  extreme  responses  in  these  two  categories.  We  recently  announced  initiation  of  an 
“open-label”  (i.e.  the  medication  is  no  longer  blinded  to  the  patients  or  their  doctor)  extension  of  this  clinical  trial.  Patients  who 
complete the Phase IIa study and who still meet the eligibility criteria may have the opportunity to take arimoclomol, at the highest 
investigative dose, for as long as an additional 6 months. 

Depending upon the results of the Phase IIa trial, we plan to initiate a subsequent Phase II trial (which we refer to as the Phase IIb 
trial) that will be powered to detect more subtle efficacy responses. Although this second trial is still in the planning stages and will be 
subject  to  FDA  approval,  it  is  expected  to  include  approximately  300  ALS  patients  recruited  from  25  clinical  sites  and  will  take 
approximately 18 months after initiation to complete. 

The  acquisition  of  the  molecular  “chaperone”  co-induction  technology  from  Biorex  represented  a  continuation  of  our  business 
strategy, adopted subsequent to our merger with Global Genomics, in July 2002, to conduct further research and development efforts 
for our pre-merger adjuvant and co-polymer technologies, including Flocor and TranzFect, through strategic relationships with other 
pharmaceutical  companies,  and  to  focus  our  efforts  on  acquiring  and  developing  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  UMMS  covering 
potential applications for its proprietary RNAi technology in the treatment of specified diseases and in the identification and screening 
of  novel  protein  targets.  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 

4 

 
 
 
 
 
 
 
 
 
 
entering  into  a  collaboration  and  invention  disclosure  agreement  with  UMMS  under  which  UMMS  will  disclose  to  us  certain  new 
technologies  developed  at  UMMS  over  a  three-year  period  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. Approximately one year remains on the technology disclosure option. 
As part of our strategic alliance with UMMS, we agreed to fund certain discovery and pre-clinical research at UMMS relating to the 
use of our technologies, licensed from UMMS, for the development of therapeutic products within certain fields. 

In  conjunction  with  some  of  our  work  with  UMMS,  we  operate  a  research  and  development  laboratory  in  Worcester, 
Massachusetts whose goal is to develop small molecule and RNAi-based therapeutics for the prevention, treatment and cure of obesity 
and type 2 diabetes. This laboratory is focusing on using our proprietary RNAi gene silencing technology, combined with genomic 
and  proteomic  based  drug  discovery  technologies,  to  accelerate  the  process  of  screening  and  identifying  potential  proprietary  drug 
targets  and  pathways  for  these  diseases.  Through  this  laboratory,  we  are  seeking  to  develop  orally  active  drugs  against  promising 
targets and pathways relevant to obesity and type 2 diabetes. 

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 
arimoclomol  for  ALS),  we  may  also  seek  to  secure  strategic  alliances  or  license  agreements  with  larger  pharmaceutical  or 
biotechnology 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 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-Induction Platform 

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  molecular  “chaperone”  proteins  to  deal  with  these  potentially  toxic  mis-folded  proteins. 
Molecular  chaperones  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 or degrade 
the mis-folded proteins. 

5 

 
 
 
 
 
 
 
 
 
 
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 mice in an ALS model, 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  diseases  like  ALS  can  be  slowed, 
halted  or  reversed.  In  test  tube  experiments,  mammalian  cells  engineered  to  have  increased  amounts  of  molecular  chaperones  are 
protected against a variety of otherwise lethal stresses. In animal studies, mice that have been genetically engineered to have increased 
amounts  of  a  molecular  chaperone  had  improved  heart  function  after  an  experimental  heart  attack.  Increased  molecular  chaperone 
amounts also significantly increased the lifespan of mice with a disease similar to ALS, called spinal and bulbar muscular atrophy. We 
believe that these studies give scientifically accepted support for new drugs like arimoclomol that are capable of boosting the stress 
response. 

Among  the  assets  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  our  molecular  chaperone  co-induction  drug  candidates  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 some of 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 scientific papers 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 Platform 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 useful in laboratory cell culture experiments and in animals (including humans) to target 
specific mRNAs, thus reducing the levels of the corresponding specific protein product that is coded for by that RNA 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 to help identify classical, orally-available small  molecule drugs and, potentially 
through the creation of a new subsidiary, for direct therapeutic applications when technically feasible. As a drug discovery tool, we 
use  RNAi  to  identify  and  validate  novel  protein  targets,  which  could  then  be  used  to  discover  small  molecule  therapeutics  for  the 
treatment  and  prevention  of  diseases  such  as  obesity  and  type  2  diabetes.  As  a  therapeutic,  we  are  conducting  pre-clinical  RNAi 
efficacy  studies  to determine  whether  to  proceed  with human  clinical  trials  using  RNAi  to silence  specific genes  that  cause  certain 
forms  of  ALS,  CMV  retinitis,  and  type  2  diabetes.  In  January  2004,  Tariq  Rana,  a  scientific  authority  in  delivery  and  stability  of 

6 

 
 
 
 
 
 
 
 
 
RNAi, and in March 2004, Dr. Craig Mello, the co-discoverer of RNAi, each joined our Scientific Advisory Board and they act in an 
advisory capacity to help us develop RNAi therapeutics for specific diseases. We are currently pursuing a plan, subject to obtaining 
necessary funding, to transfer all of our RNAi therapeutics assets into a newly-formed subsidiary to accelerate the development and 
commercialization of drugs based on RNAi technology. In such event, the Company would continue to use its RNAi gene silencing 
technology as a drug discovery tool to facilitate its small molecule drug discovery program. 

In  mammals  and  human  cells,  gene  silencing  can  be  triggered  by  dsRNA  molecules  present  in  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 four clinical trials using 
RNAi, namely trials for age-related macular degeneration by Acuity Pharmaceuticals and Sirna Therapeutics, for respiratory syncytial 
virus by Alnylam Pharmaceuticals and for diabetic macular edema by Acuity Pharmaceuticals. 

Product Development 

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. 

We recently entered the clinical stage of drug development in ALS with the initiation of a Phase II clinical program with our lead 
small  molecule  product  candidate  arimoclomol  for  the  treatment  of  ALS.  Arimoclomol  has  received  Orphan  Drug  and  Fast  Track 
designation  from  the  U.S.  Food  and  Drug  Administration.  The  initial  portion  of  the  Phase  II  clinical  program  was  initiated  in 
September  2005.  We  expect  enrollment  in  this  Phase  IIa  trial  to  be  complete  shortly,  and  expect  to  announce  results  in  the  third 
quarter of 2006. 

In October 2003, we entered into sponsored research agreements with UMMS and Massachusetts General Hospital, pursuant to 
which we sponsored certain ALS research at those institutions utilizing our proprietary RNAi 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,  through  which  we  have  agreed  to  fund  approximately  $870,000  of  research 
related to the development of an RNAi therapeutic targeting the mutant form of SOD1 that causes certain forms of ALS, of which 
$654,000  had  been  paid  as  of  December  31,  2005.  We  anticipate  that  the  development  of  this  program  will  be  continued  by  our 
planned RNAi subsidiary. 

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 

7 

 
 
 
 
 
 
 
 
 
 
 
principal investigator under our sponsored research agreement with Massachusetts General Hospital. Under the agreement, we have 
funded  approximately  $556,000  of  sponsored  research  at  Massachusetts  General  Hospital  to  increase  our  basic  understanding  of 
certain  aspects  of  the  ALS  disease  process.  In  March  2004,  Dr.  Brown  joined  our  Scientific  Advisory  Board  and  entered  into  a 
consulting agreement with us. 

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  in  the  identification  and screening of novel protein  targets  and  as  a  potential  therapeutic  in 
certain  defined  areas  that  include  obesity,  type  2  diabetes,  ALS  and  CMV,  as  well  as  a  DNA-based  HIV  vaccine  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 a three-year period 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. Approximately one year remains on the technology disclosure 
option. 

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,  received  a $16 million grant from  the NIH. This grant funded  a Phase I clinical  trial  of  a vaccine  candidate using  our 
licensed technology. We have previously announced that the vaccine candidate demonstrated very promising interim Phase I clinical 
trial results that indicate its ability to produce potent antibody responses with neutralizing activity against multiple HIV viral strains, 
and we  expect  to  announce  final  results  from  the  Phase  I  clinical  trial  in  mid-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. 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. 

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 $842,000 for 2006, 
although a significant portion of those commitments may be assumed by our planned RNAi subsidiary. Our license agreements with 
UMMS require us to make payments of an aggregate of up to $94,000 per year to maintain all of our licenses, with such aggregate 
annual payments increasing to as much as $154,000 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 $250,000 during 2006 and 2007. In the event that we 
were to successfully develop a product in each of the categories of obesity/type 2 diabetes, ALS, CMV 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 up to $375,000 in 2006 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 in our Worcester laboratory and 
scientists  at  UMMS,  as  part  of  our  strategic  alliance,  are  focused  on  using  cultured  adipocytes  (fat  cells)  as  a  model  system  for 

8 

 
 
 
 
 
 
 
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 through a 
newly-created subsidiary, 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 RNAi 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 2007. 

Although we initially intend to develop arimoclomol 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 2007, as arimoclomol has already been tested in two Phase I clinical trials. 

Research and Development Laboratory 

In addition to the obesity and diabetes work being done under our sponsored research agreement with UMMS, our research and 
development  laboratory  located  in  Worcester,  Massachusetts  is  working  to  develop  orally-active  small-molecule  and  RNAi-based 
drugs for the prevention and treatment 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 and treat 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  laboratory  is  focused  on 
using  a  structure-based  drug  discovery  approach  to  accelerate  the  process  of  screening  and  identifying  potential  proprietary  drug 
targets and pathways for these diseases. Through our laboratory, we are seeking to develop orally-administered drugs that are based on 
promising targets and pathways that we may be able to identify. 

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 screening 
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. 

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 

The following discussion describes our primary scientific programs prior to our merger with Global Genomics on July 19, 2002, 

and the status of those programs today. 

Therapeutic Copolymer Program 

Before the Global Genomics merger, 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 

9 

 
 
 
 
 
 
 
 
 
 
 
 
 
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 54%, 93% and 
81% of our total revenues for 2005, 2004 and 2003, 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 each of April 2004 and January 2005, we received additional 
$100,000  milestone  fees  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. 

Genomics Investments 

In connection with our merger with Global Genomics in July 2002, 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 

10 

 
 
 
 
 
 
 
 
 
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, in 2004, returned its licensed intellectual property to the Minnesota Research Fund. 

Research and Development Expenditures 

Expenditures  for  research  and  development  activities  were  $9.1  million,  $9.0  million  and  $4.4  million  during  the  years  ended 
December 31, 2005, 2004 and 2003, 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, 
including our supply of arimoclomol used for our clinical program. 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 molecular chaperone co-induction and other 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, Ono Pharmaceuticals, Trophos SA, FaustPharmaceuticals SA 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., Cephalon, Inc., Ceregene, Inc., Elan Pharmaceuticals, plc, H. Lundbeck A/S, Phytopharm plc, and Schwarz Pharma AG. 

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,  Acuity  Pharmaceuticals,  Nastech 
Pharmaceutical Company Inc., Nucleonics, Inc. 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., 
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. 

12 

 
 
 
 
 
 
 
 
Employees 

As  of  December  31,  2005,  we  had  28  employees,  18  of  whom  were  engaged  in  research  and  development  activities  and  10  of 
whom  were  involved  in  management  and  administrative  operations.  All  of  the  full-time  employees  engaged  in  research  and 
development activities hold Ph.D. degrees. 

Item 1A. 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 $15.1 million, $16.4 million and $17.8 million 
for  the  years  ended  December  31,  2005, 2004 and 2003,  respectively,  and  we  had  an  accumulated  deficit  of  approximately  $121.3 
million as of December 31, 2005. 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. 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 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 $184,000, $428,000, and $94,000 during the years ended December 31, 2005, 2004 and 2003, 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 expect to incur losses from operations until such time, if ever, as we can generate significant recurring revenues. On March 7, 
2006, we completed a private placement financing and received net proceeds of approximately $12.4 million. Although we believe 
that we have adequate financial resources to support our currently planned level of operations into the third quarter of 2007, we will be 
dependent on obtaining financing from third parties in order to maintain our operations, including our Phase II clinical program with 
arimoclomol for ALS, our planned levels of operations for our obesity and type 2 diabetes laboratory, our planned RNAi subsidiary 
and  our  ongoing  research  and development  efforts  related  to our other  small  molecule  drug  candidates,  and  in order  to  continue to 
meet our obligations to UMMS. 

We have no commitments from third parties to provide us with any additional debt or equity financing, and may not be able to 
obtain future financing on favorable terms, or at all. A lack of needed financing would force us to reduce the scope of, or terminate, 
our operations, or to seek to merge with or to 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 54%, 93% and 81% of our total revenues for the 
years  ended December 31, 2005,  2004  and  2003,  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. Since TranzFect is to be used as a component in 

13 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 our small molecule drug candidates, and 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  or 
biotechnology companies for this purpose. 

There can be no assurance that any of 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  recently-completed  Phase  I  clinical  trial  conducted  by 
UMMS and Advanced BioScience Laboratories 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 may 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 

14 

 
 
 
 
 
 
 
 
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  UMMS  relating  to  the 
development  of  therapeutic  products  based  on  UMMS’s  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 approximately $1,186,000 million for 2006 and approximately $450,000 for 2007. 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 and an HIV vaccine, under our licenses, those milestone payments could aggregate 
up to $16.1 million. 

We estimate that the Phase II clinical program with arimoclomol for ALS, including the recently-initiated Phase IIa trial and the 
Phase IIb trial that we expect to initiate soon after completion of the present Phase IIa trial subject to FDA approval, will require us to 
expend approximately $17.8 million over a period of 24 to 30 months. 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 successfully develop any of the products acquired from Biorex, 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. 

Under our license for our HIV vaccine candidate, 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. Although we are seeking NIH or other governmental funding for these future trials, we do not have, 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  laboratory,  our  planned  sponsored  research  funding  for  Massachusetts  General 
Hospital,  our  Phase  II  clinical  program  with  arimoclomol  for  ALS  and  our  development  of  our  small  molecule  drug  candidates, 
substantially  exceed  our  current  financial  resources.  Although  we  raised  approximately  $12.4  million  in  March  2006,  net  of 
transaction  expenses,  those  required  expenditures  will  nonetheless  require  us  to  raise  additional  capital  or  to  secure  a  licensee  or 
strategic partner in order to maintain our operations, including our Phase II clinical program with arimoclomol for ALS, our planned 
levels  of  operations  for  our  obesity  and  type  2  diabetes  laboratory,  our  planned  RNAi  subsidiary  and  our  ongoing  research  and 
development efforts related to our other small molecule drug candidates, and in order to continue to meet our obligations to UMMS. 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 laboratory. 

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.  

15 

 
 
 
 
 
 
 
 
 
 
 
•  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 Therapeutics Using RNAi is Unproven and May Never Lead to 
Marketable Products 

The RNAi 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. 

Our  Planned  RNAi  Subsidiary  May  Not  Be  Able  to  Obtain  Sufficient  Funding,  and  We  May  Not  Control  a  Majority  of  the 
Planned Subsidiary if We Obtain Financing 

We are currently pursuing a plan to transfer all of our RNAi therapeutics assets into a newly-formed subsidiary to accelerate the 
development and commercialization of drugs based on RNAi technology. Although we believe that this structure may facilitate our 
obtaining additional financing to pursue our RNAi development efforts, we have no commitments or arrangements for any financing, 
and there is no assurance that we will be able to obtain financing for this purpose. Our planned RNAi subsidiary will be only partially 
owned by us. Depending upon the amount and terms of its future financing activities, we may not control the subsidiary, or may share 
control with other shareholders whose interests may not be directly aligned with ours. It also is possible that any products developed 
by the RNAi subsidiary could eventually compete with our products for some disease indications, such as ALS, type 2 diabetes and 
obesity. 

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. 

In September 2005, we initiated Phase II clinical testing for arimoclomol for ALS. There are no assurances that the clinical testing 
will  be  successful,  or  that  the  FDA  will  permit  us  to  commence  our  planned  Phase  IIb  clinical  trial  upon  the  completion  of  our 
ongoing Phase IIa clinical trial. Any additional requirements imposed by the FDA in connection with the ongoing Phase IIa trial, or in 
connection with our planned Phase IIb trial, could add further time and expense for us to carry out this trial. 

16 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
We believe that the FDA may accept the completion of a successful Phase II clinical program as sufficient to enable us to submit a 
New Drug Application, or NDA; however there are no assurances that the FDA will accept our Phase II program 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 
significantly  beyond  our  estimated  costs,  and  the  time  to  completion  of  clinical  testing  would  be  delayed.  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 Laboratory May Not Be Able to Develop Products 

In order to develop new obesity and type 2 diabetes products, we will first need to identify appropriate drug targets and pathways. 
We are 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  are  currently 
seeking a strategic alliance with a major pharmaceutical or biotechnology company to complete the development, clinical testing and 
manufacturing and marketing of our potential obesity and type 2 diabetes products, which are at an early stage of development, 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  our  Scientific  Advisory  Board,  Dr.  Jack  Barber,  our  Senior  Vice  President  —  Drug 
Development,  and  Dr.  Mark  A.  Tepper,  our  Senior  Vice  President  —  Drug  Discovery,  in  establishing  our  scientific  goals  and 
strategies. 

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.  

17 

 
 
 
 
 
 
 
 
 
 
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 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, Alnylam Pharmaceuticals, Acuity Pharmaceuticals, Nastech 
Pharmaceutical Company Inc., Nucleonics, Inc., Benitec Ltd. 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 Acomplia(R) by Sanofi-Aventis SA, 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.,  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, Ono Pharmaceuticals, Trophos SA, FaustPharmaceuticals SA 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., Cephalon, Inc., Ceregene, Inc., Elan Pharmaceuticals, plc, H. Lundbeck A/S, Phytopharm plc, and Schwarz Pharma AG.

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. 

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, including the supply of arimoclomol used in our Phase II clinical trials. Accordingly, we are and 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  have  a  manufacturing  supply 
arrangement in place with respect to the clinical supplies for both the Phase IIa and Phase IIb trials for arimoclomol for ALS. We do 
not  otherwise  have  manufacturing  supply  arrangements  for  our  other  product  candidates,  including  any  of  the  licensed  RNAi 
technology, the other 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. In particular, although we conducted certain due diligence regarding the patents and patent 
applications acquired from Biorex and received certain representations and warranties from Biorex in connection with the acquisition, 
the patents and patent applications acquired from Biorex were issued or filed, as applicable, prior to our acquisition and thus there can 
be no assurance that the validity, enforceability and ownership of those patents and patent applications will be upheld if challenged by 
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 commercial marketing of these products. We have obtained clinical trial insurance for our recently-
initiated Phase IIa clinical trial with arimoclomol for the treatment of ALS and will seek to obtain such insurance for any other clinical 
trials that we conduct, including the planned Phase IIb clinical trial for arimoclomol, as well as liability insurance for any products that 
we market, although there can be no assurance that we will be able to obtain additional insurance in the amounts we seek 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. 

Compliance  with  Requirements  of  Section  404  of  the  Sarbanes-Oxley  Act  of  2002  Will  Increase  Our  Costs  and  Require 
Additional Management Resources, and We May Not Successfully Comply 

As directed by Section 404 of the Sarbanes-Oxley Act of 2002, the SEC adopted rules requiring public companies to include a 
report of management on the company’s internal controls over financial reporting in their annual reports on Form 10-K. In addition, 
the  independent  registered  public  accounting  firm  auditing  the  company’s  financial  statements  must  attest  to  and  report  on 
management’s  assessment  of  the  effectiveness  of  the  company’s  internal  controls  over  financial  reporting.  Although  the  SEC  has 
postponed the effectiveness of this requirement several times, if the SEC does not postpone or otherwise alter the requirement again, 
then  we  expect  that  it  will  first  apply  to  our  annual  report  on  Form  10-K  for  our fiscal  year ending  December  31,  2006.  If we  are 
required to comply, we will incur significant legal, accounting, and other expenses and compliance will occupy a substantial amount 
of time of our board of directors and management. Uncertainty exists regarding our ability to comply with these requirements by the 
SEC’s current deadlines. If we are unable to complete the required assessment as to the adequacy of our internal control reporting or if 
we conclude that our internal controls over financial reporting are not effective or if our independent registered public accounting firm 
is  unable  to  provide  us  with  an  unqualified  report  as  to  the  effectiveness  of  our  internal  controls  over  financial  reporting  as  of 
December 31, 2006 and future year ends, investors could lose confidence in the reliability of our financial reporting. In addition, while 
we  plan  to  expand  our  staff  to  assist  in  complying  with  the  additional  requirements  when  and  if  they  become  applicable,  we  may 
encounter substantial difficulty attracting qualified staff with requisite experience due to the high level of competition for experienced 
financial professionals. 

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. 

20 

 
 
 
 
 
 
 
 
 
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, 2005, there were outstanding stock options and warrants to purchase approximately 24.7 million shares of our 
common stock at exercise prices ranging from $0.20 to $2.73 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  addition, warrants  issued  in  connection with  our financings  in  2003 contain 
anti-dilution provisions that are triggered upon certain events, including any issuance of securities by us below the market price. In the 
event  that  those  anti-dilution  provisions  are  triggered  by  us  in  the  future,  we  would  be  required  to  reduce  the  exercise  price,  and 
increase the number of shares underlying, those warrants, which would 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 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  registered  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.  In  April  2006,  we  expect  to  file  a 
registration  statement  to  register  10,650,794  shares  of  our  common  stock  and  an  additional  5,325,397  shares  of  our  common  stock 
issuable upon the exercise of warrants in connection with the $13.4 million private equity financing that we completed in March 2006. 
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 first quarter of 2006. We 

21 

 
 
 
 
 
 
 
 
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.  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 2. Properties 

Our operations are based in Los Angeles, California, and Worcester, Massachusetts. The lease for our headquarters facility in Los 
Angeles covers approximately 4,700 square feet of office space and expires in June 2008. The lease for our laboratory in Worcester 
covers approximately 6,900 square feet of office and laboratory space and expires in December 2007. Our facilities are suitable and 
adequate for our current operations. 

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.

Factors Affecting Comparability 

In  January  2005,  we  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 
$19.4 million. 

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  initiated  a  Phase  II  clinical  trial  for  one  of  the  drug  candidates, 
arimoclomol, for ALS in September 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. 

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. Our small molecule therapeutics efforts include our clinical development of 
three oral drug candidates that we acquired in October 2004, including a Phase II trial initiated in September 2005, as well as our drug 
discovery  operations  conducted  at  our  laboratory  in  Worcester,  Massachusetts.  Development  work  on  RNAi,  a  relatively  recent 
technology for silencing genes in living cells and organisms, is still at an early stage, and we are aware of only four clinical tests of 
therapeutic applications using RNAi that have yet been initiated by any party. In addition to our work in RNAi and small molecule 
therapeutics, we recently announced that a novel HIV DNA + protein vaccine exclusively licensed to us and developed by researchers 
at the University of Massachusetts Medical School, or UMMS, and Advanced BioScience Laboratories, and funded by the National 
Institutes of Health, demonstrated promising interim Phase I clinical trial results that indicate its potential to produce potent antibody 
responses with neutralizing activity against multiple HIV viral strains. We have also entered into strategic alliances with respect to the 
development of several other products using our other technologies. 

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 based on molecular 
“chaperone”  co-induction  technology,  with  broad  therapeutic  applications  in  neurology,  type  2  diabetes,  cardiology  and  diabetic 
complications.  The  acquired  assets  include  three  oral,  clinical  stage  drug  candidates  and  a  library  of  500  small  molecule  drug 
candidates. We recently entered the clinical stage of drug development with the initiation of a Phase II clinical program with our lead 
small  molecule  product  candidate  arimoclomol  for  the  treatment  of  ALS.  Arimoclomol  has  received  Orphan  Drug  and  Fast  Track 
designation from the U.S. Food and Drug Administration. 

24 

 
 
 
 
 
 
 
 
 
 
The  initial  Phase  II  clinical  trial  that  we  have  initiated  for  arimoclomol  for  ALS  (which  we  refer  to  as  the  Phase  IIa  trial)  is  a 
multicenter, double-blind, placebo-controlled study of approximately 80 ALS patients enrolled at ten clinical centers across the U.S. 
Patients will receive either placebo (a capsule without drug), or one of three dose levels of arimoclomol capsules three times daily, for 
a period of 12 weeks. This treatment phase will be immediately followed by a one-month period without drug. The primary endpoints 
of this Phase IIa trial are safety and tolerability. Secondary endpoints include a preliminary evaluation of efficacy using two widely 
accepted surrogate markers, the revised ALS Functional Rating Scale (ALSFRS-R), which is used to determine patients’ capacity and 
independence  in  13 functional  activities,  and  Vital  Capacity  (VC), an  assessment  of  lung capacity.  The  trial  is  powered  to  monitor 
only extreme responses in these two categories. We recently announced initiation of an “open-label” (i.e. the medication is no longer 
blinded to the patients or their doctor) extension of this clinical trial. Patients who complete the Phase IIa study and who still meet the 
eligibility  criteria  may  have  the  opportunity  to  take  arimoclomol,  at  the  highest  investigative  dose,  for  as  long  as  an  additional  6 
months. 

Depending upon the results of the Phase IIa trial, we plan to initiate a subsequent Phase II trial (which we refer to as the Phase IIb 
trial) that will be powered to detect more subtle efficacy responses. Although this second trial is still in the planning stages and will be 
subject  to  FDA  approval,  it  is  expected  to  include  approximately  300  ALS  patients  recruited  from  25  clinical  sites  and  will  take 
approximately 18 months after initiation to complete. 

The  acquisition  of  the  molecular  “chaperone”  co-induction  technology  from  Biorex  represented  a  continuation  of  our  business 
strategy, adopted subsequent to our merger with Global Genomics, in July 2002, to conduct further research and development efforts 
for our pre-merger adjuvant and co-polymer technologies, including Flocor and Tranzfect, through strategic relationships with other 
pharmaceutical  companies,  and  to  focus  our  efforts  on  acquiring  and  developing  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  UMMS  covering 
potential  applications  for  its  proprietary  RNAi  technology  in  the  treatment  of  specified  diseases.  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  a  three-year 
period 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. Approximately one year remains on the technology disclosure option. As part of our strategic alliance with UMMS, we agreed 
to fund certain discovery and pre-clinical research at UMMS relating to the use of our technologies, licensed from UMMS, for the 
development of therapeutic products within certain fields. 

We have no significant revenues and we expect not to have significant revenues and to continue to incur significant losses over the 
next several years. Our net losses may increase from current levels primarily due to activities related to our collaborations, technology 
acquisitions,  ongoing  and  planned  clinical  trials,  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 sales of equity securities and, to a much lesser extent, upon payments from our strategic 
partners and licensees and upon proceeds received upon the exercise of options and warrants, to generate the funds needed to finance 
our  business  plans  and  operations.  We  will  be  required  to  obtain  significant  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,  gifts  and  grants,  and  milestone 
payments  under  existing  and  future  collaborative  arrangements.  However,  we  have  no  commitment  or  arrangements  for  such 
additional funding. 

Research and Development 

Following  our  2003  acquisition  of  rights  to  new  technologies  from  UMMS  and  our  2004  acquisition  of  the  clinical  assets  of 
Biorex, we initiated research and development programs for products based upon those technologies. Expenditures for research and 
development activities related to continuing operations were $9.1 million, $9.0 million and $4.4 million for the years ended December 
31, 2005, 2004 and 2003, respectively, with research and development expenses representing approximately 58%, 53% and 39% of 
our  total  expenses  for  the  years  ended  December  31,  2005,  2004  and  2003,  respectively.  Included  in  research  and  development 

25 

 
 
 
 
 
 
 
 
 
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.” 

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  molecular 
chaperone co-induction technology or 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 

26 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 

Clinical Trial Expenses 

Clinical trial expenses, which are included in research and development expenses, include obligations resulting from our contracts 
with  various  clinical  research  organizations  in  connection  with  conducting  clinical  trials  for  our  product  candidates.  We  recognize 
expenses for these activities based on a variety of factors, including actual and estimated labor hours, clinical site initiation activities, 
patient enrollment rates, estimates of external costs and other activity-based factors. We believe that this method best approximates the 
efforts expended on a clinical trial with the expenses we record. We adjust our rate of clinical expense recognition if actual results 
differ from our estimates. 

Stock-based Compensation 

We  apply  Accounting  Principles  Board  Opinion  No.  25  (“APB  25”),  Accounting  for  Stock  Issued  to  Employees,  and  related 
interpretations  in  accounting  for  our  stock-based  employee  compensation  plans,  rather  than  the  alternative  fair  value  accounting 
method provided for under Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (“SFAS 
123”). In the Notes to Consolidated Financial Statements, we provide pro forma disclosures in accordance with SFAS 123 and related 
pronouncements. Under APB 25, compensation expense is recorded on the date of grant of an option to an employee or member of the 
Board only if the fair market value of the underlying stock at the date of grant exceeds the exercise price. In addition, we have granted 
options to certain outside consultants, which are required to be measured at fair value and recognized as compensation expense in our 
financial  statements.  We  apply  the  Black-Scholes  option-pricing  model  for  estimating  the  fair  value  of  options,  which  involves  a 
number  of  judgments  and  variables,  including  estimates  of  the  life  of  the  options  and  expected  volatility  which  are  subject  to 
significant  change.  A  change  in  the  fair  value  estimate  could  have  a  significant  effect  on  the  amount  of  pro  forma  compensation 
expense calculated. 

In December 2004, the FASB released its revised standard, SFAS No. 123(R) (SFAS  123(R)”), “Share-Based Payment.” SFAS 
123(R) requires that a public entity measure the cost of equity-based service awards based on the fair value of the award on the date of 
grant.  That  cost  will  be  recognized  over  either  the  vesting  period  or  the  period  during  which  an  employee  is  required  to  provide 
service in exchange for the award. We are required to adopt the provisions of SFAS 123(R) for periods after January 2006, and we 
will adopt the new requirements using the modified prospective transition method. The adoption of SFAS 123(R) requires us to value 
stock  options  granted  prior  to  adoption  of  SFAS  123(R)  under  the  fair  value  method  and  expense  these  amounts  in  the  income 
statement over the stock option’s remaining vesting period. The adoption of SFAS 123(R) will result in recognition of additional non-
cash stock-based compensation expense and, accordingly, will increase net losses in amounts which likely will be considered material, 
although it will not impact our cash position. 

We account for equity instruments issued to non-employees in accordance with the provisions of SFAS 123 and Emerging Issues 
Task Force Issue (“EITF”) No. 96-18, Accounting for Equity Instruments that Are Issued to other than Employees for Acquiring, or in 
conjunction with Selling Goods, or Services (“ EITF 96-18”) which require that such equity instruments are recorded at their fair value 
on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity 
instruments vest. Non-employee stock-based compensation charges are amortized over the vesting period on a straight-line basis. 

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  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, in 2004, returned its licensed intellectual property to the Minnesota Research Fund. 

Estimated Facility Abandonment Accrual 

Subsequent  to  our  merger  with  Global  Genomics  in  2002,  we  recorded  a  loss  of  $563,000  associated  with  the  closure  of  our 
Atlanta  headquarters  and  our  relocation  to  Los  Angeles.  This  loss  represented  the  total  remaining  lease  obligations  and  estimated 
operating costs through the remainder of the lease term, less estimated sublease rental income and deferred rent at the time. In August 
2005, we entered into a lease termination agreement pursuant to which we were released from all future obligations on the lease in 
exchange for a one-time $110,000 payment and the forfeiture of a $49,000 security deposit. As a result of this agreement, we realized 
a $164,000 offset against third quarter general and administrative expenses. 

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.

Liquidity and Capital Resources 

At December 31, 2005, we had cash, cash equivalents and short-term investments of $8.3 million and total assets of $9.9 million 
compared to $3.0 million and $5.0 million, respectively, at December 31, 2004. Working capital totaled $6.3 million at December 31, 
2005, compared to $1.2 million at December 31, 2004. 

To date, we have relied primarily upon sales of equity securities and, to a much lesser extent, payments from our strategic partners 
and licensees and upon proceeds received upon the exercise of options and warrants, to generate funds needed to finance our business 
and operations. As a result of the $12.4 million equity financing, net of expenses, that we completed in March 2006, we believe that 
we have adequate working capital to support our currently planned level of operations into the third quarter of 2007, including our 
current and planned clinical trials for arimoclomol, drug discovery efforts related to additional product candidates, working capital and 
general corporate purposes. Included in our planned expenses are approximately $3.2 million for our Phase II clinical program with 
arimoclomol for ALS during 2006, and an additional $4.5 million in 2007 and $6.3 million in 2008. The cost of our clinical program 
for ALS could vary significantly from our current projections due to any additional requirements imposed by the FDA in connection 
with  the  ongoing  Phase  IIa  trial,  or  in  connection  with  our  planned  Phase  IIb  trial,  or  if  actual  costs  are  higher  than  current 
management estimates for other reasons. In the event that actual costs of our clinical program for ALS, or any of our other ongoing 
research activities, are significantly higher than our current estimates, we may be required to significantly modify our planned level of 
operations. In the future, we will be dependent on obtaining financing from third parties in order to maintain our operations, including 
our Phase II clinical program with arimoclomol for ALS, our planned levels of operations for our obesity and type 2 diabetes research 
laboratory  and  our  ongoing  research  and  development  efforts  related  to  our  other  small  molecule  drug  candidates,  and  in  order  to 
continue to meet our obligations to UMMS. We currently have no commitments from any third parties to provide us with capital. We 
cannot assure that additional funding will be available to us on favorable terms, or at all. If we fail to obtain additional funding when 
needed,  we  would  be  forced  to  scale  back,  or  terminate,  our  operations,  or  to  seek  to  merge  with  or  to  be  acquired  by  another 
company. 

For the year ended December 31, 2005, net cash provided by investing activities consisted of $964,000, of which $1.0 million was 
from the redemption of short-term securities, which was partially offset by the acquisition of $48,000 of property and equipment. We 
expect capital spending to increase during 2006 over our 2005 levels to support our increasing research and development efforts and 
the  implementation  of  Sarbanes-Oxley.  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. Net cash provided by investing activities for the 
year ended December 31, 2003 was $1.2 million which was primarily due to the maturity of held-to-maturity investments acquired in 
2002. 

Cash  provided  by  financing  activities  for  the  year-ended  December  31,  2005  was  $19.8  million.  The  cash  provided  includes 
$256,000 received upon the exercise of stock options and warrants. Additionally, we raised $19.6 million through the sale of equity, of 
which $19.4 million was raised in connection with a private equity financing, net of expenses, that closed in January 2005. Net cash 
provided by financing activities in the year ended December 31, 2004 was $4.4 million. The cash provided was the result of $526,000 
received upon the exercise of stock options and warrants and the $4.0 million private equity financing completed in October 2004. Net 
cash  provided  by  financing  activities  for  the  year  ended  December  31,  2003  was  $14.4  million.  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. 

Our net loss for the year-ended December 31, 2005 was $15.1 million, which resulted in net cash used in operating activities of 
$14.5 million. Adjustments to reconcile net loss to net cash used in operating activities for the year-ended December 31, 2005 include 
$586,000 of common stock, options and warrants issued in lieu of cash for research and development and general and administrative 
services,  as  well  as  a  net  change  in  assets  and  liabilities  of  $210,000  offset  by  the  recording  of  $217,000  in  depreciation  and 
amortization. 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  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 

29 

 
 
 
 
 
 
 
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 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. 

We believe that we have adequate working capital to allow us to operate at our currently planned levels into the third quarter of 
2007.  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 $2.5 million during 2005, and if we retain our current license portfolio, we expect 
expenditures to be approximately $1.2 million during 2006. 

We will require significant additional capital in order to fund the completion of our Phase II clinical program with our lead small 
molecule  product  candidate  arimoclomol  for  the  treatment  of  ALS,  which  commenced  in  September  2005,  and  the  other  ongoing 
research  and  development  related  to  the  drug  candidates  acquired  from  Biorex  in  October  2004.  We  spent  $3.8  million  on  the 
arimoclomol clinical program in 2005, and we estimate that the overall program, including the ongoing Phase IIa trial and the planned 
Phase IIb trial that we expect to initiate soon after completion of the present Phase IIa trial subject to FDA approval, will require us to 
expend approximately $3.2 million in 2006, and an additional $10.8 million over the following 12 to 18 months. However, we may 
incur substantial additional expense and the trial may be delayed if the FDA requires us to generate additional pre-clinical or clinical 
data in connection with the clinical trial, or the FDA requires us to revise significantly our planned protocol for the Phase IIb. 

Any additional capital may be provided by potential milestones payments pursuant to our licenses with Merck and Vical, both of 
which  relate  to  Tranzfect,  or  our  license  with  SynthRx  related  to  Flocor,  or  by  potential  payments  from  future  strategic  alliance 
partners or licensees of our technologies. However, Merck is at an early stage of clinical trials of a product utilizing TransFect and 
Vical has only recently commenced a Phase IIa clinical trial of a product using TransFect, so there is likely to be a substantial period 
of time, if ever, before we receive any further significant payments from Merck or Vical. 

We  intend  also  to  pursue  other  sources  of  capital,  although  we  do  not  currently  have  commitments  from  any  third  parties  to 
provide  us  with  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,  gifts,  and  grants  or  otherwise  is  subject  to  market  conditions  and  out  ability  to  identify 
parties that are willing and able to enter into such arrangements on terms that are satisfactory to us. Depending upon the outcome of 
our fundraising efforts, the accompanying financial information may not necessarily be indicative of future operating results or future 
financial condition. 

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.

We  have  no  current  commitments  for  capital  expenditures  in  2006;  however,  we  anticipate  incurring  capital  expenditures  in 
connection with the expansion of our laboratory. As of December 31, 2005, we had no committed lines of credit or other committed 
funding or long-term debt. As of December 31, 2005, 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 
following:

We  have  employment  agreements  with  our  executive  officers,  the  terms  of  which  expire  at  various  times  through  July  2008. 
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 $0.9 million of compensation payable to members of our Scientific Advisory Board through 2008, and a total of $1.6 
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 and CMV. 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 a three-year period 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. 
Approximately  one  year  remains  on  the  technology  disclosure  option.  As  of  December  31,  2005,  we  have  made  cash  payments  to 
UMMS totaling $1.1 million 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 the then-aggregate fair market value of $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, 2005, we had consolidated net operating loss carryforwards for income tax purposes of $35.6 million, which will 
expire in 2006 through 2025 if not utilized. We also have research and development tax credits and orphan drug tax credits available 
to reduce income taxes, if any, of $6.4 million, which will expire in 2006 through 2025 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 recorded net losses of $15.1 million, $16.4 million and $17.8 million during the years ended 2005, 2004 and 

2003. 

We earned an immaterial amount in licensing fees during the years ended 2005, 2004 and 2003. All future licensing fees under out 
current  licensing  agreements  are  dependent  upon  successful  development  milestones  being  achieved  by  the  licensor.  During  fiscal 
2006, we are not anticipating receiving any significant licensing fees.

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 $9.1 million in 2005, $9.0 million in 
2004 and $4.4 million in 2003. 

Research and development expenses incurred during 2005 relate primarily to (i) the initiation of our Phase II clinical program for 
arimoclomol  in  ALS,  (ii)  our  ongoing  research  and  development  related  to  other  drug  candidates  purchased  from  Biorex,  (iii)  our 
research and development activities conducted at UMMS related to the technologies covered by the UMMS license agreements, (iv) 
our collaboration and invention disclosure agreement pursuant to which UMMS has agreed to disclose certain inventions to us and 
provide us with the right to acquire an option to negotiate exclusive licenses for those disclosed technologies, and (v) the on-going 
small molecule drug discovery operations at our Massachusetts laboratory. Although our future research and development activities 
could  vary  substantially,  our  research  and  development  activities  will  remain  substantial  in  the  future  as  a  result  of  commitments 
related  to  the  foregoing  activities.  Research  and  development  expenses  presented  in  the  accompanying  consolidated  financial 
statements  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 Massachusetts laboratory. Research and 
development  expenses  incurred  in  2003  were  primarily  for  the  acquisition  and  licensing  of  intellectual  property  and  the 
commencement  of  operations  of  our  Massachusetts  laboratory.  All  research  and  development  costs  related  to  the  activities  of  our 
laboratory are expensed. No in-process research and development costs were eligible for capitalization at the time we purchased the 
minority interest in our prior subsidiary, CytRx Laboratories. 

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 of the acquisition price was expensed in 2004 as in-process research and development. 

As  compensation  to  members  of  our  scientific  advisory  board  and  consultants,  and  in  connection  with  the  acquisition  of 
technology, we issue shares of our common stock, stock options and warrants to purchase shares of our common stock. 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 $0.2 
million, $1.4 million, and $2.9 million during 2005, 2004, and 2003, respectively. 

In  2006,  we  expect  our  research  and  development  expenses  to  increase  primarily  as  a  result  of  our  ongoing  Phase  II  clinical 
program with arimoclomol and related studies for the treatment of ALS. We estimate that the Phase II trial and related studies will 
cost approximately $17.8 million, of which approximately $3.8 million had been spent as of December 31, 2005, and will last between 
24 to 30 months. Additionally, we estimate that our costs related to the activities of our Massachusetts laboratory will be consistent 
with expenses incurred in 2005.

General  and  administrative  expenses  include  all  administrative  salaries  and  general  corporation  expenses.  Our  total  general  and 
administrative expenses, including common stock, stock options and warrants issued, were $6.4 million in 2005, $7.9 million in 2004 
and $7.0 million in 2003. Our general and administrative expenses, net of common stock, stock options and warrants issued, were $6.1 
million in 2005, $5.9 million in 2004 and $3.8 million in 2003. General and administrative expenses during 2005 as compared to 2004 
were relatively constant. During 2005 the Company incurred approximately $0.9 million in higher salary expense than 2004, although 
the difference in total general and administrative expense was substantially smaller between 2005 and 2004 due to one-time expenses 
associated with our change in auditors in 2004, severance paid to certain members of management in the first half of 2004, and the 
settlement  of  certain  legal  proceedings,  for  which  there  was  no  comparable  expenses  in  2005.  For  the  same  reasons,  general  and 
administrative expenses during 2004 were higher as compared to 2003. We expect our general and administrative expenses in 2006 to 
be slightly higher than those incurred in 2005, as a result of our ongoing Sarbanes-Oxley compliance efforts. 

From  time  to  time,  we  issue  shares  of  our  common  stock  or  warrants  or  options  to  purchase  shares  of  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 $0.4 million, $2.0 million, and $3.1 million during 2005, 
2004, and 2003, 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.  During  2004,  as  our  business  strategy 
matured, 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 expenses were $217,000, $104,000, and $2,000 in 2005, 2004 and 2003 respectively. Depreciation 
and amortization expenses recorded in 2005 reflect the depreciation of fixed assets located at our obesity and diabetes laboratory, as 
well as $75,000 of amortization expenses related to the molecular screening library acquired from Biorex in October 2004 and placed 
in service in March 2005. Depreciation incurred in 2004 consists almost entirely of depreciation on assets acquired for our obesity and 
diabetes laboratory. During the fourth quarter of 2003 and the first two quarters of 2004, we increased our capital spending as part of 
our overall strategy to establish our obesity and diabetes laboratory. As our need for additional equipment was nominal during 2005, 
our  net  capital  assets  declined  to  $726,000,  net  of  depreciation,  from  $895,000  at  December  31,  2004.  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. 

Severance and other contractual payments to officers 

In  accordance  with  a  Mutual  General  Release  and  Severance  Agreement  in  May  2004,  we  paid  our  former  General  Counsel, 
approximately  $52,000  and  12  months  of  related  benefits,  and  vested  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 paid our former Chief Financial Officer, approximately $150,000 and 18 months of related benefits, and vested options 
to purchase 105,000 shares of our common stock that were granted upon the commencement of his employment. 

Loss on facility abandonment 

Subsequent  to  our  merger  with  Global  Genomics  in  2002,  we  recorded  a  loss  of  $478,000  associated  with  the  closure  of  our 
Atlanta  headquarters  and  our  relocation  to  Los  Angeles.  This  loss  represented  the  total  remaining  lease  obligations  and  estimated 
operating costs through the remainder of the lease term, less estimated sublease rental income and deferred rent at the time. In August 
2005, we entered into a lease termination agreement pursuant to which we were released from all future obligations on the lease in 
exchange for a one-time $110,000 payment and the forfeiture of a $49,000 security deposit. As a result of this agreement, we realized 
a $163,000 offset against third quarter general and administrative expenses. 

Interest income 

Interest income was $206,000 in 2005, as compared to $60,000 in 2004 and $82,000 in 2003. The variances between years are 

primarily attributable to the cash available for investment and higher interest yields.

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  $81,000  in  2005,  $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.  On  June  30,  2005,  we  repurchased  the  outstanding  5%  interest  in  CytRx 
Laboratories from Dr. Michael Czech, and on September 30, 2005, we completed the merger of CytRx Laboratories with and into the 
Company. 

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 to our audited financial statements illustrates the effect on net income and earnings per share 
for 2005, 2004 and 2003 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  adopt  SFAS  123(R) 
effective  January  1,  2006,  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 $0.6 million in 2006, but may be significantly greater dependant 
upon levels of share-based payments granted in the future, option valuation models utilized and assumptions selected at the time of the 
future grants. 

In December 2004, the FASB issued SFAS 153 (“SFAS 153”), “Exchanges of Nonmonetary Assets, an amendment of APB No. 
29, Accounting for Nonmonetary Transactions.” SFAS 153 requires exchanges of productive assets to be accounted for at fair value, 
rather than at carryover basis, unless (1) neither the asset received nor the asset surrendered has a fair value that is determinable within 
reasonable limits or (2) the transactions lack commercial substance. SFAS 153 is effective for nonmonetary asset exchanges occurring 
in fiscal periods beginning after June 15, 2005. Adoption of this standard did not have a material effect on our consolidated financial 
statements. 

In  May  2005,  the  FASB  issued  Statement  of  Financial  Accounting  Standards  No.  154,  “Accounting  Changes  and  Error 
Corrections”,  (“SFAS  154”).  SFAS  154  replaces  APB  Opinion  No.  20,  “Accounting  Changes,”  and  SFAS  No.  3,  “Reporting 
Accounting Changes in Interim Financial Statements,” and changes the requirements for the accounting for and reporting of a change 
in accounting principle. We are required to adopt SFAS 154 in 2006. Our results of operations and financial condition will only be 
impacted  by  SFAS  154  if  we  implement  changes  in  accounting  principles  that  are  addressed  by  the  standard  or  correct  accounting 
errors in future periods. 

Related Party Transactions 

Dr. Michael Czech, who was until June 30, 2005 a 5% minority shareholder of our prior subsidiary, CytRx Laboratories, and who 
is a member of our Scientific Advisory Board, is an employee of UMMS and is the principal investigator for a sponsored research 
agreement between CytRx and UMMS. During each of 2005 and 2004, Dr. Czech was paid $80,000 for his Scientific Advisory Board 
services.  In  addition,  during  2005  and  2004,  we  paid  UMMS  $1,410,000  and  $403,000,  respectively,  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. 

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. If interest rates had varied by 10% in 2005, it would not have had a material effect on our 
statement of operations or cash flows for 2005 based upon our December 31, 2005 balances. 

Item 8. Financial Statements and Supplementary Data 

Our consolidated financial statements and supplemental schedule and notes thereto as of December 31, 2005 and 2004, and for 
each of the three years ended December 31, 2005, 2004 and 2003, together with the independent registered public accounting firms’ 
reports thereon, are set forth on pages F-1 to F-21 of this Annual Report. 

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 December 31, 2005, the end of 
the  period  covered by  this  Annual  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, 2005 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 SEC rules and forms. 

There was no change in our internal control over financial reporting that occurred during the quarter ended December 31, 2005, 

that materially affected, or is 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 Capital 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 a standing Audit Committee currently composed of Messrs. Selter, Link, Rubinfeld and Wennekamp. 
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 2005 were complied with. 

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 2005, directors who were employees of our company received no 
compensation for their service as directors or as members of board committees. 

Effective  October  1,  2005,  our  non-employee  directors  receive  a  quarterly  retainer  of  $2,000  ($8,000  for  the  Chairman  of  the 
Board), a fee of $2,000 for each board meeting attended ($750 for meetings attended by teleconference and for board actions taken by 
unanimous written consent) and $1,000 for each committee meeting attended. Non-employee directors who serve as the Chairman a 
Board  committee  receive  an  additional  $1,500  for  each  meeting  attended  as  the  Chairman  of  the  Nomination  and  Governance 
Committee  or  the  Compensation  Committee  and  an  additional  $2,000  for  each  meeting  attended  as  the  Chairman  of  the  Audit 
Committee. Prior to October 2005, our non-employee directors received a quarterly retainer of $1,500, 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 served as Chairman of a Board committee received an additional 
$500 for each meeting attended as the Chairman of the Nomination and Governance Committee or the Compensation Committee and 
an additional $1,000 for each meeting attended as the Chairman of the 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. Past option grants were made subject to vesting in annual increments of 1/3rd each, subject to the 
director remaining as a director.

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 May 17, 2005 to continue through July 1, 2008. As an incentive to enter the amended and restated employment agreement, Mr. 
Kriegsman was granted as of May 17, 2005, a ten-year, nonqualified option under our 2000 Long-Term Incentive Plan to purchase 
300,000 shares of our common stock at a price of $0.79 per share. The employment agreement will automatically renew in July 2008 
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 $400,000. 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. 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 Chairman 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.

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 March 10, 2006 by (1) each person who is known by us to beneficially own more than five 
percent of our 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  March  10,  2006  (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 69,515,867 shares of our common stock outstanding as of March 10, 2006. 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

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 an obesity and type 2 diabetes research laboratory in Worcester, Massachusetts (see Note 11). On September 
30, 2005, the Company completed the merger of CytRx Laboratories, Inc., previously a wholly owned subsidiary of the Company and 
the owner of its Massachusetts laboratory (the “Subsidiary”), with and into the Company. 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  its  laboratory  in  Worcester,  Massachusetts.  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). In addition, the Company recently announced that a novel HIV DNA + protein boost vaccine exclusively 
licensed  to  the  Company  and  developed  by  researchers  at  University  of  Massachusetts  Medical  School  and  Advanced  BioScience 
Laboratories, and funded by the National Institutes of Health, demonstrated promising interim Phase I clinical trial results that indicate 
its  potential  to  produce  potent  antibody  responses  with  neutralizing  activity  against  multiple  HIV  viral  strains.  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 based on 
molecular  “chaperone”  co-induction  technology,  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 Company 
recently entered the clinical stage of drug development with the initiation of a Phase II clinical program with its lead small molecule 
product candidate arimoclomol for the treatment of ALS. Arimoclomol has received Orphan Drug and Fast Track designation from 
the U.S. Food and Drug Administration. 

To  date,  the  Company  has  relied  primarily  upon  selling  equity  securities  and,  to  a  much  lesser  extent,  upon  payments  from  its 
strategic partners and licensees and upon proceeds received upon the exercise of options and warrants to generate the funds needed to 
finance its operations. Management believes the Company’s cash and cash equivalents balances are sufficient to meet projected cash 
requirements into the third quarter of 2007. The Company will be required to obtain significant additional funding in order to execute 
its long-term business plans, although it does not currently have commitments from any third parties to provide it with capital. 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, less the minority interest, are included from 
September 17, 2003 until June 30, 2005, when the Company purchased the outstanding 5% interest in the Subsidiary (see Note 11) 
and the Subsidiary became wholly owned by the Company. The accounts of Global Genomics are included since July 19, 2002 (see 
Note 12). 

Revenue Recognition — Biopharmaceutical revenues consist of license fees and milestone payments from strategic alliances from 

pharmaceutical companies as well as contract research. Service revenues consist of government grants, and laboratory consulting. 

Monies  received  for  license  fees  are  deferred  and  recognized  ratably  over  the  performance  period  in  accordance  with  Staff 
Accounting  Bulletin  (SAB)  No.  101,  Revenue  Recognition.  Milestone  payments  will  be  recognized  upon  achievement  of  the 
milestone  as  long  as  the  milestone  is  deemed  substantive  and  the  Company  has  no  other  performance  obligations  related  to  the 
milestone and collectibility is reasonably assured, which is generally upon receipt, or recognized upon termination of the agreement 
and all related obligations. Unbilled costs and fees represent revenue recognized prior to billing. Deferred revenue represents amounts 
received prior to revenue recognition. 

59 

 
 
 
 
 
 
 
 
 
 
 
Revenues from contract research, government grants, and consulting fees are recognized over the respective contract periods as the 
services are performed, provided there is persuasive evidence or an arrangement, the fee is fixed or determinable and collection of the 
related  receivable  is  reasonably  assured.  The  percentage  of  services  performed  related  to  contract  research,  government  grants  and 
consulting services is based upon the ratio of the number of direct labor hours performed to date to the total hours the Company is 
obligated to perform under the related contract. 

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, accounts 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. 

Molecular  Library—The  Molecular  Library,  a  collection  of  chemical  compounds  that  we  believe  may  be  developed  into  drug 
candidates, are stated at cost and depreciated over five years; the estimated useful life of the molecular library, which is less than the 
remaining life of the related patents. On an annual basis, or whenever there is a triggering event that might suggest an impairment, 
management  evaluates  the  realizability  of  the  molecular  library  to  determine  whether  its  carrying  value  has  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  from  the  patents  is  uncertain.  Patent  costs  are  therefore  expensed  as 
incurred. 

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 and warrants) 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 24.7 million shares, 14.5 million shares and 10.1 million shares at December 31, 2005, 2004 and 2003, respectively. 

Shares Reserved for Future Issuance — As of December 31, 2005, the Company has reserved approximately 3.96 million 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  accounts  for  stock-based  compensation  using  the  intrinsic  value  method  in 
accordance with APB No. 25 (Note 14), Accounting for Stock Issued to Employees (“APB 25”). Under APB 25, when stock options 
are issued with an exercise price equal to the market price of the underlying stock price on the date of grant, no compensation expense 
is  recognized.  The  Company  continues  to  follow  the  disclosure-only  provisions  of  SFAS  No.  123,  Accounting  for  Stock-Based 
Compensation (“SFAS 123”), as amended by SFAS No. 148, which requires the disclosure of proforma net income and earnings per 
share as if the Company had applied the fair value recognition provisions of SFAS 123. 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. 

Other  comprehensive  income/(loss)  —  The  Company  follows  the  provisions  of  Statement  of  Financial  Accounting  Standards 
(“SFAS”)  No.  130,  “Reporting  Comprehensive  Income,”  which  requires  separate  representation  of  certain  transactions,  which  are 
recorded directly as components of shareholders’ equity. The Company has no other comprehensive income/(loss).

3. Recent Accounting Pronouncements 

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) requires a company using the modified prospective transition method to 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  Company  expects  the  adoption  of  SFAS  123(R)  to  result  in  recognition  of  additional  non-cash  stock-based  compensation 
expense  which  will  increase  net  losses  in  amounts  which  likely  will  be  considered  material,  although  it  will  not  impact  its  cash 
position (see Note 2). 

In December 2004, the FASB issued SFAS 153 (“SFAS 153”), “Exchanges of Nonmonetary Assets, an amendment of APB No. 
29, Accounting for Nonmonetary Transactions.” SFAS 153 requires exchanges of productive assets to be accounted for at fair value, 
rather than at carryover basis, unless (1) neither the asset received nor the asset surrendered has a fair value that is determinable within 
reasonable limits or (2) the transactions lack commercial substance. SFAS 153 is effective for nonmonetary asset exchanges occurring 
in  fiscal  periods  beginning  after  June  15,  2005.  Adoption  of  this  standard  did  not  have  a  material  effect  on  the  Company’s 
consolidated financial statements. 

In  May  2005,  the  FASB  issued  Statement  of  Financial  Accounting  Standards  No.  154,  “Accounting  Changes  and  Error 
Corrections”,  (“SFAS  154”).  SFAS  154  replaces  APB  Opinion  No.  20,  “Accounting  Changes,”  and  SFAS  No.  3,  “Reporting 
Accounting Changes in Interim Financial Statements,” and changes the requirements for the accounting for and reporting of a change 
in accounting principle. We are required to adopt SFAS 154 in 2006. the Company’s results of operations and financial condition will 
only  be  impacted  by  SFAS  154  if  it  implements  changes  in  accounting  principles  that  are  addressed  by  the  standard  or  correct 
accounting errors in future periods. 

4. Investments 

At December 31, 2005, the Company did not have any investments. At December 31, 2004, the Company held approximately $1.0 
million  in  short-term  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,  2005,  the  Company  had  $150,000  on  deposit  with  its  landlords  related  to  its  leased  facilities,  which  were 
classified  as  other  assets.  At  December  31,  2004  the  Company  held  approximately  $51,000  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, 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. 
During 2005, the letter of credit was replaced by a cash deposit for the lease on the rental property.

At December 31, 2004, the molecular library had been purchased from Biorex, but was not placed in service by the Company, as 
the compounds were not physically received until March 2005. Therefore, no amortization of the related patents was recorded in 2004. 
The molecular library is being amortized over 60 months, which is less than the estimated effective life of the patents. The result will 
be that the Company will incur approximately $89,000 in amortization over the next four years and approximately $16,000 in 2010, 
the final year.

Subsequent to the Company’s merger with Global Genomics in 2002, it recorded a loss of $563,000 associated with the closure of 
the Atlanta headquarters and its relocation to Los Angeles. This loss represented the total remaining lease obligations and estimated 
operating costs through the remainder of the lease term, less estimated sublease rental income and deferred rent at the time. In August 
2005, the Company entered into a lease termination agreement pursuant to which it was released from all future obligations on the 
lease in exchange for a one-time $110,000 payment and the forfeiture of a $49,000 security deposit. As a result of this agreement the 
Company realized $164,000 in other income.

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 
2008. 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  $0.9  million  of  compensation  payable  to  members  of  CytRx’s 
Scientific Advisory Board, and a total of $1.6 million of salary and guaranteed bonuses payable to CytRx’s executives. 

Rent  expense  under  operating  leases  during  2005,  2004  and  2003  was  approximately  $380,000,  $364,000  and  $258,000, 

respectively. 

The Company applies the disclosure provisions of FASB Interpretation No. (“FIN”) 45, “Guarantor’s Accounting and Disclosure 
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others,” (“ FIN 45”), to its agreements that contain 
guarantee or indemnification clauses. The Company provides (i) indemnifications of varying scope and size to certain investors and 
other parties for certain losses suffered or incurred by the indemnified party in connection with various types of third-party claims; and 
(ii)  indemnifications  of  varying  scope  and  size  to  officers  and  directors  against  third  party  claims  arising  from  the  services  they 
provide to us. These indemnifications and guarantees give rise only to the disclosure provisions of FIN 45. To date, the Company has 
not incurred material costs as a result of these obligations and does not expect to incur material costs in the future. Accordingly, the 
Company has not accrued any liabilities in its consolidated financial statements related to these indemnifications or guarantees. 

10. Private Placements of Common Stock 

In  January  2005,  the  Company  entered  into  a  Stock  Purchase  Agreement  with  a  group  of  institutional  and  other  investors  (the 
“January 2005 Investors”). The January 2005 Investors purchased, for an aggregate purchase price of $21.3 million, 17,334,494 shares 
of the Company’s common stock and warrants to purchase an additional 8,667,247 shares of the Company’s common stock, at $2.00 
per share, expiring in 2010. After consideration of offering expenses, net proceeds to the Company were approximately $19.4 million. 
The shares and the shares underlying the warrants issued to the January 2005 Investors were subsequently registered. In addition, the 
Company issued approximately $158,000 worth of common stock in February 2005. 

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 June 30, 2005, the Company issued 650,000 shares of its common stock to Dr. Michael Czech as part of a transaction in which 
the  Company  purchased  Dr.  Czech’s  5%  interest  in  the  Subsidiary,  which,  as  a  result  of  the  purchase,  became  a  wholly-owned 
subsidiary of CytRx. The Subsidiary was subsequently merged with and into the Company on September 30, 2005. The purchase of 
Dr. Czech’s interest in the Subsidiary was consummated pursuant to the terms of the Stockholders Agreement dated September 17, 
2003, by and among CytRx, the Subsidiary and Dr. Czech, 300,000 of the shares of CytRx common stock issued to Dr. Czech were 
unrestricted and in exchange for his 5% interest in the Subsidiary. That stock is valued at $0.91 per share, the then fair value of the 
common stock, for financial statement purposes. The non-cash transaction was accounted for using purchase accounting, and resulted 
in $184,000 of goodwill for financial statement purposes, which represents the difference between the market value of the 300,000 
unrestricted shares issued to Dr. Czech and the fair value of the minority interest at June 30, 2005. 

12. Merger with Global Genomics 

In July 2002, CytRx acquired 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 at 
the  time  of  the  merger  owned  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. 

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. 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 its investment in Blizzard had no value, 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 
Less: Equity-method losses to date 
Less: Impairment charge

In accordance with a Mutual General Release and Severance Agreement in May 2004, the Company paid the Company’s former 
General Counsel, $52,000 and 12 months of related benefits, and immediately vested 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  paid  the  Company’s  former  Chief  Financial  Officer,  $150,000  and  18  months  of  related 
benefits, and immediately vested options to purchase 105,000 shares of its common stock that were granted upon the commencement 
of his employment.

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 financings that were consummated on October 4, 2004 and January 20, 2005, the 
Company re-priced warrants to purchase approximately 2.8 million shares as a result of anti-dilution provisions in those warrants that 
were triggered by the Company’s issuance of common stock in these equity financings at a price below the closing market price on the 
date of the transaction. The warrants were issued in connection with the Company’s May and September 2003 private investment in 
public  equity  (PIPE)  transactions.  The  antidilution  provision  is  required  to  be  accounted  for  as  a  liability  under  SFAS  150  and  is 
adjusted on a mark to market basis. To date the fair value of the liability has been immaterial. Pursuant to the anti-dilution provision, 
the exercise price of these warrants was reduced from $3.05 per share, to $2.70 per share, and the number of shares underlying the 
warrants was increased to approximately 3.1 million shares. 

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. 

We recorded approximately $586,000, $1.1 million and $1.6 million of non-cash charges related to the issuance of stock options 

and warrants to certain consultants in exchange for services during 2005, 2004 and 2003, 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  $35.6  million  of  net  operating  losses 
available  to  offset  against  future  taxable  income,  subject  to  certain  limitations.  Such  losses  expire  in  2006  through  2025  as  of 
December 31, 2005. CytRx also has an aggregate of approximately $6.4 million of research and development and orphan drug credits 
available for offset against future income taxes that expire in 2006 through 2025. 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, the Company’s limited operating history in its core business and 
lack of profitability, uncertainties of the commercial viability of its technology, the impact of government regulation and healthcare 
reform  initiatives,  and  other  risks  normally  associated  with  biotechnology  companies,  the  Company  has  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.

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, 2005 and 2004, 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, and the Company’s subsequent private investment in public equity transactions, 
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 the dates of those transactions. 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): 

Federal benefit at statutory rate 
State income taxes, net of Federal taxes

University of Massachusetts Medical School(UMMS) — 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,  the  then  fair  value  of  the  common  stock.  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 a 
three-year period 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.  Approximately  one  year  remains  on  the  technology  disclosure  option.  As  of  December  31,  2005,  CytRx  has  not 
acquired or made any payments to acquire any options under that Collaboration 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 

Dr.  Michael  Czech,  who  was  until  June  30,  2005  a  5%  minority  shareholder  of  the  Company’s  prior  subsidiary,  CytRx 
Laboratories,  and  who  is  a  member  of  the  Company’s  Scientific  Advisory  Board,  is  an  employee  of  UMMS  and  is  the  principal 
investigator for a sponsored research agreement between the Company and UMMS. During each of 2005 and 2004, Dr. Czech was 
paid $80,000 for his Scientific Advisory Board services. In addition, during 2005 and 2004, the Company paid UMMS $1,410,000 
and $403,000, respectively, under a sponsored research agreement to fund a portion of Dr. Czech’s research. 

20. Subsequent Event 

On March 2, 2006, the Company completed a $13.4 million private equity financing in which we issued 10,650,794 shares of our 
common stock and warrants to purchase an additional 5,325,397 shares of our common stock at an exercise price of $1.54 per share. 
Net  of  investment  banking  commissions,  legal,  accounting  and  other  fees  related  to  the  transaction,  we  received  proceeds  of 
approximately $12.4 million.

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, 2005 
and 2004 and the related consolidated statements of operations, stockholders’ equity and cash flow for the three years in the period 
ended  December  31,  2005.  We  have  also  audited  the  schedule  listed  in  the  accompanying  index  on  page  F-1.  These  financial 
statements  and  schedule  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the 
financial statements and schedule 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 and 
schedule 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.  An  audit  also 
includes  assessing  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position 
of CytRx Corporation and subsidiaries as of December 31, 2005 and 2004 and the results of its operations and its cash flows for the 
three years in the period ended December 31, 2005, 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.
