PART II. OTHER INFORMATION
 
 ITEM 1. LEGAL PROCEEDINGS
  
 ITEM 1A. RISK FACTORS
 We wish to caution readers that the following important factors, among others, in some cases have
affected our results and in the future could cause our actual results and needs to vary materially
from forward-looking statements made from time to time by us on the basis of managements
then-current expectations. The business in which we are engaged is in a rapidly changing and
competitive market and involves a high degree of risk, and accuracy with respect to forward-looking
projections is difficult.
 The Company has marked with an asterisk those risk factors that reflect changes from the risk
factors included in the Companys Annual Report on Form 10-K filed with the SEC.
 *Our lead product candidate, Junovan, may never obtain regulatory approval.
   38




---



##### Table of Contents



*Even
if we receive regulatory approval for Junovan, we may not be able to
commercialize it immediately or market it successfully.
    *The process of developing immunotherapeutic products requires significant research and
development, preclinical testing and clinical trials, all of which are extremely expensive and
time-consuming and may not result in a commercial product.
  
    
    the results of preclinical studies may be inconclusive, or they may not be indicative
of results that will be obtained in human clinical trials;
    
    after reviewing test results, we may abandon projects that we might previously have
believed to be promising;
    
    after reviewing test results, our collaborators may abandon projects that we might
believe are still promising and we would either have to bear the operating expenses and
capital requirements of continued development of our therapeutic cancer vaccines or abandon
the projects outright;

##### Table of Contents




    
    we, our collaborators or government regulators may suspend or terminate clinical trials
if the participating subjects or patients are being exposed to unacceptable health risks;
    
    clinical trials may be delayed as a result of difficulties in identifying and enrolling
patients who meet trial eligibility criteria;
    
    safety and efficacy results attained in early human clinical trials may not be
indicative of results that are obtained in later clinical trials; and
    
    the effects of our product candidates may not be the desired effects or may include
undesirable side effects that preclude regulatory approval or limit their commercial use,
if approved.
  *Our principal source of revenues and cash receipts is a collaboration agreement under which our
partner has limited obligations.
  Our revenues and operating results are likely to fluctuate.
  
    
    any payments from Sanofi-Aventis and any other current or future collaborative partners;

*Unexpected or undesirable side effects or other characteristics of our products and technology may
delay or otherwise hurt the development of our drug candidates, or may expose us to significant
liability that could cause us to incur significant costs.
   Adverse publicity regarding the safety or side effects of the technology approach or products of
others could negatively impact us and cause the price of our common stock to decline.
  *Our treatment approach may not prove effective.

or in sufficient quantities to be recognized by immune system cells, such as T cells or

    the immune response stimulated by the immunotherapeutic agent is not strong enough to
destroy all of the cancer cells ; or
    
    cancer cells may, through various biochemical mechanisms, escape an immune response.
  *If we cannot enter into and maintain strategic collaborations on acceptable terms in the future,
we may not be able to develop products in markets where it would be too costly or complex to do so
on our own.
  *If our collaboration or license arrangements are unsuccessful, our revenues and product
development may be limited.
  
    
    collaborations and licensee arrangements may be terminated, in which case we will
experience increased operating expenses and capital requirements if we elect to pursue
further development of the product candidate;
    
    collaborators and licensees may delay clinical trials and prolong clinical development,
underfund a clinical trial program, stop a clinical trial or abandon a product candidate;
    
    expected revenue might not be generated because milestones may not be achieved and
product candidates may not be developed;
    
    collaborators and licensees could independently develop, or develop with third parties,
products that could compete with our future products;
    
    the terms of our contracts with current or future collaborators and licensees may not
be favorable to us in the future;
    
    a collaborator or licensee with marketing and distribution rights to one or more of our
products may not commit enough resources to the marketing and distribution of our products,
limiting our potential revenues from the commercialization of a product; and

commercialization of our product candidates, or result in significant and costly litigation

Our failure to obtain issued patents and, consequently, to protect our proprietary technology,
could hurt our competitive position.

If we are unable to protect our trade secrets, we may be unable to protect from competitors our
interests in proprietary know-how that is not patentable or for which we have elected not to seek
patent protection.
  Some of our programs will be funded by the U.S. government and, therefore, the U.S. government may
have rights to certain of our technology and could require us to grant licenses of our inventions
to third parties.
