Cougar Biotechnology Announces Agreement with FDA on Special Protocol Assessment for Phase III trial of CB7630 (Abiraterone Acetate)
Los Angeles, CA, April 1, 2008 /PSA Rising/ -- Cougar Biotechnology, Inc. (NASDAQ: CGRB) today announced that it reached agreement with the U.S. Food and Drug Administration (FDA) under a Special Protocol Assessment (SPA) for its planned Phase III clinical trial of the Company's lead drug candidate CB7630 (abiraterone acetate). The SPA is a written agreement between the trial's sponsor and the FDA regarding the design, endpoints, and planned statistical analysis approach of the Phase III trial to be used in support of a new drug application (NDA). The European Medicines Agency (EMEA) has also provided protocol advice consistent with that of the FDA regarding the Company's Phase III trial design.
Pursuant to the SPA, the Phase III trial will be a randomized, double-blind, placebo-controlled trial of CB7630 plus prednisone in patients with metastatic castration-resistant prostate cancer who have failed docetaxel-based chemotherapy. Similar to the patient populations in the Company's Phase II trials COU-AA-003 and COU-AA-004, patients are allowed to have received up to two prior chemotherapy regimens before entering the trial. The trial is expected to enroll approximately 1160 patients who will be randomized (2:1) to receive either CB7630 plus prednisone or placebo plus prednisone. The trial will be conducted at approximately 150 sites in North America, Europe and Australia. The primary endpoint of the trial will be overall survival. The Company expects to begin patient enrollment later this month.
Alan H. Auerbach, Chief Executive Officer and President of Cougar Biotechnology, said, "Obtaining FDA agreement on our overall Phase III trial design, patient population and endpoints represents an important milestone in the global development of CB7630 and for Cougar as a company."
Arturo Molina, M.D., M.S., FACP, Senior Vice President of Clinical Research and Development of Cougar, added, "We are pleased to be able to reach agreement with the FDA on our Phase III trial design. We look forward to commencing patient enrollment in this Phase III trial shortly."About Cougar Biotechnology
