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 across the full spectrum of advanced prostate cancer disease states. 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 United States.

About MDV3100
MDV3100 is an investigational therapy in clinical development for advanced prostate cancer. In a Phase 1-2 trial in 140 patients with advanced prostate cancer published in The Lancet, encouraging antitumor activity was noted with MDV3100 across endpoints. In preclinical experiments published in Science in April 2009, the triple-acting, oral androgen receptor antagonist provided more compIete suppression of the androgen receptor pathway than bicalutamide, the most commonly used anti-androgen. MDV3100 slows growth and induces cell death in bicalutamide-resistant cancers 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. In the preclinical experiments published in Science, MDV3100 was superior to bicalutamide in each of these three actions.

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.
