Corporate Update
  • On July 27, 2010, data from a Phase 1 trial testing AG-707 in genital herpes was presented at the International Herpes Workshop. The data showed that 100% of evaluable patients receiving AG-707 with our proprietary QS-21 Stimulon® adjuvant demonstrated a statistically significant CD4+ T-cell response to HSV-2 antigens detected by interferon-gamma ELISPOT, and the majority of those patients (63%) demonstrated a CD8+ T-cell response. Eliciting both CD4+ and CD8+ T-cell responses is a first of its kind achievement in herpes therapy. This data suggests that there is potential for AG-707 to manage outbreaks and transmission, impacting the epidemiology of the virus. AG-707 represents proof of concept for a platform technology enabling development of additional heat shock protein-based infectious disease vaccines. The company plans to seek a partner to further clinical development of its infectious disease technology.
  • On May 20, 2010, data from a Phase 2 clinical trial testing Oncophage vaccine in recurrent glioma, or brain cancer, was presented at the International Conference on Brain Tumor Research and Therapy. Data from the first 32 patients showed median survival of 44 weeks compared with a historical median of 26 weeks. Approximately 70% of these patients survived beyond 36 weeks, and 41% survived for at least one year. All patients tested exhibited a significant generalized innate immune response, and 92% showed an adaptive tumor-antigen specific immune response demonstrated by a significant increase in CD4+ and CD8+ T-cell responses. A Phase 2 trial testing Oncophage in newly diagnosed glioma continues to enroll. The trials are being led by Dr. Andrew Parsa of the University of California, San Francisco (UCSF) and are sponsored by the National Institutes of Health in conjunction with patient advocacy groups.
  • Antigenics is working with the Pediatric Brain Tumor Consortium to explore initiation of a Phase 1 trial testing Oncophage in pediatric brain tumors.
  • Based on the encouraging results to date with the use of Oncophage in glioma, Antigenics is assessing late-stage development strategies that could lead to potential US registration.
  • Sales of Oncophage for intermediate-risk renal cell carcinoma (RCC; kidney cancer) in Russia continue on a very limited basis, as the company continues to explore local distribution partnerships that might enable broader commercialization efforts and potential government reimbursement.
  • Antigenics continues to evaluate its options in Europe with respect to Oncophage for non-metastatic RCC, with a final decision anticipated by the end of 2010. Potential outcomes include discontinuation of efforts in Europe, planning for resubmission of a marketing authorization application, implementation of named patient or similar programs, and/or a local partnership agreement.
  • A survival registry following patients from a Phase 3 trial testing Oncophage in non-metastatic RCC has been closed, and final data analysis is underway.
  • The company continues to explore both academic and industry collaborations as a means of advancing preclinical and clinical research utilizing Oncophage in combination with other novel and potentially synergistic immunotherapies, such as anti-CTLA-4 antibody.
  • Antigenics’ QS-21 licensees, such as GlaxoSmithKline, continue clinical development of multiple vaccines containing Antigenics’ QS-21 investigational adjuvant. Phase 3 programs include vaccines for malaria, melanoma and non-small cell lung cancer. Antigenics would be entitled to milestone payments as these programs advance, as well as royalties for at least 10 years after commercial launch. The cost of developing and marketing these vaccines is assumed by the company’s licensees. The first products containing QS-21 could be launched in 2013/2014.
  • As of July 20, 2010, the company is non-compliant with the minimum bid price continued listing requirement of the NASDAQ Capital Markets. There is no change in the trading of our common stock at this time, and Antigenics has an initial period of until January 18, 2011 to regain compliance. The company can also appeal a potential delisting.
