MEDIVATION REPORTS THIRD QUARTER 2010

FINANCIAL RESULTS AND PROVIDES CORPORATE UPDATE

— Conference Call Today at 4:30 p.m. Eastern Time —

SAN FRANCISCO, November 5, 2010 – Medivation, Inc. (NASDAQ: MDVN) today provided a corporate update and reported its financial results for the third quarter ended September 30, 2010.

“In the third quarter, we began the expansion of our MDV3100 development program into earlier stage patients with the initiation of the Phase 3 PREVAIL trial, which is enrolling men with advanced prostate cancer who have not yet received chemotherapy. Additionally, we believe that the positive interim analysis of the abiraterone Phase 3 study is a net positive for MDV3100, as it provides further clinical validation for the importance of the androgen receptor signaling pathway in advanced prostate cancer,” said David Hung, MD, president and chief executive officer of Medivation. “Together with our partner Pfizer, we continue to investigate dimebon’s potential clinical benefit in the ongoing Phase 3 HORIZON trial in Huntington disease and the ongoing Phase 3 CONCERT trial in mild-to-moderate Alzheimer’s disease patients who are taking donepezil. We remain on track to complete enrollment in the CONCERT trial this year and look forward to announcing top-line results from the HORIZON trial in the first half of 2011.”
