Medivation and Astellas Complete Enrollment in Phase 3 AFFIRM trial of MDV3100 in Advanced Prostate Cancer
San Francisco and Tokyo, November 30 (ots/PRNewswire) - Medivation, Inc. and Astellas Pharma Inc. today announced that patient enrollment was completed on November 15, 2010 in the Phase 3 AFFIRM study of the investigational drug MDV3100, a novel, triple-acting oral androgen receptor antagonist, in patients with advanced prostate cancer who have previously been treated with chemotherapy.
"There has been a lot of positive news for advanced prostate cancer patients over this past year, and the completion of patient enrollment in AFFIRM is yet another significant achievement in the development of new therapies to treat this devastating disease," said Lynn Seely, M.D., chief medical officer of Medivation.
"While AFFIRM is focused on patients with the most advanced stage of disease, earlier stage prostate cancer patients are also in need of new treatment options," said Steve Ryder, MD, president, Astellas Pharma Global Development."The first step in our expanded development of MDV3100 into earlier stage patients is our ongoing Phase 3 PREVAIL trial, in which we are studying advanced prostate cancer patients who are chemotherapy naïve. In addition, Medivation and Astellas plan to initiate two Phase 2 trials in earlier stage prostate cancer early next year."
The randomized, double-blind, placebo-controlled Phase 3 AFFIRM study enrolled 1,199 patients. The trial is evaluating 160 mg/day of MDV3100 versus placebo. The primary endpoint is overall survival, and secondary endpoints include progression-free survival, safety and tolerability. The AFFIRM study is being conducted at sites in the United States, Canada, Europe, Australia, South America and South Africa.
About the Medivation/Astellas Collaboration
In October 2009, Medivation and Astellas entered into a global agreement to jointly develop and commercialize MDV3100. The companies are collaborating on a comprehensive development program that includes studies to develop MDV3100 for both early-stage and advanced prostate cancer. Subject to receipt of regulatory approval, the companies will jointly commercialize MDV3100 in the U.S. and Astellas will have responsibility for commercializing MDV3100 outside the U.S. Medivation received a $110 million up-front payment upon entering into the collaboration agreement, and is eligible to receive up to $335 million in development milestone payments, up to $320 million in commercial milestone payments, 50% of profits on sales in the U.S., and tiered, double-digit royalties on sales outside the U.S.
MDV3100 is an investigational therapy in clinical development for advanced prostate cancer. The novel, triple-acting, oral androgen receptor antagonist has been shown to slow growth and induces cell death in bicalutamide-resistant cell-lines via three complementary actions - MDV3100 blocks testosterone binding to the androgen receptor, impedes movement of the androgen receptor to the nucleus of prostate cancer cells (nuclear translocation) and inhibits binding to DNA. Preclinical data comparing MDV3100 and bicalutamide in each of these three actions was published in Science in April 2009.
About Prostate Cancer
Prostate cancer is the second most common non-skin cancer among men in the world and it is the sixth leading cause of cancer death among men worldwide. Patients whose prostate tumors have stopped responding to, or are growing despite the use of, active hormone treatment strategies are considered to have advanced prostate cancer. These patients have a poor prognosis and few treatment options.
Medivation, Inc. is a biopharmaceutical company focused on the rapid development of novel small molecule drugs to treat serious diseases for which there are limited treatment options.
