(BW HealthWire) — IDEC Pharmaceuticals Corporation (Nasdaq:IDPH) today announced the signing of exclusive patent and technology license agreements with the National Cancer Institute (NCI) and the University of Iowa Research Foundation (UIRF), strengthening the Company’s oncology pipeline by developing new investigational immunotherapies for prostate cancer.
Under the terms of the NCI license agreement, which was preceded by a Cooperative Research and Development Agreement (CRADA), IDEC has been granted an exclusive worldwide license for the use of PAGE-4 plasmid DNA and PAGE-4 protein for the development and commercialization of a therapeutic vaccine to treat human prostate cancer.
Under the terms of the UIRF license agreement, IDEC has been granted an exclusive, worldwide license for the use of a prostate-specific, surface-reactive monoclonal antibody, named 5E10, for evaluation as a potential therapy of prostate carcinoma.
“Our oncology strategy involves capitalizing on recent advances in genomics and bioinformatics while leveraging IDEC’s core expertise and experience in oncology, monoclonal antibody and radioimmunotherapy technologies,” said Nabil Hanna, Ph.D., IDEC’s chief scientific officer. “We anticipate developing PAGE-4 antigen with our patented PROVAX(TM) adjuvant technology as a therapeutic cancer vaccine and we intend to radiolabel an engineered form of the 5E10 monoclonal antibody with Yttrium 90 for effective targeting of the radioisotope to prostate cancer cells. This is the same radioisotope we used in our Phase III clinical trials for the investigational agent Zevalin(TM) (Ibritumomab tiuxetan), for which IDEC anticipates filing a Biologics License Application in the fourth quarter 2000.”

Prostate Cancer’s Prevalence

Prostate cancer is the second leading cause of cancer death in men, with an estimated 31,900 deaths in 2000, according to the American Cancer Society. The ACS also estimates that 180,400 new cases in the United States will be diagnosed in 2000.
IDEC Pharmaceuticals focuses on the commercialization and development of targeted therapies for the treatment of cancer and autoimmune diseases. IDEC’s antibody products act chiefly through immune system mechanisms, exerting their effect by binding to specific, readily targeted immune cells in the patient’s blood or lymphatic systems.
