MEDIVATION REPORTS FIRST QUARTER 2009 FINANCIAL RESULTS AND PROVIDES CORPORATE UPDATE

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

SAN FRANCISCO, May 11, 2009 – Medivation, Inc. (NASDAQ: MDVN)today reported on its corporate progress and financial results for the first quarter ended March 31, 2009.

“We continue to make significant progress with both of our product candidates — Dimebon in patients with Alzheimer’s and Huntington’s diseases and MDV3100 in patients with prostate cancer. Having received written permission from the FDA to initiate a pivotal Phase 3 trial of MDV3100 in castration-resistant prostate cancer, we are on track to be in Phase 3 testing in all of our clinical programs this year,” said David Hung, M.D., president and chief executive officer of Medivation. “We expect to achieve a significant milestone in June – completion of enrollment in our six-month, confirmatory, pivotal Phase 3 CONNECTION trial in mild-to-moderate Alzheimer’s disease. And as part of our plan to support a broad and differentiated label for Dimebon in Alzheimer’s disease, we are pleased to have initiated the Phase 3 CONCERT trial of Dimebon in combination with donepezil (Aricept^®), and intend to begin two additional Phase 3 trials in moderate-to-severe Alzheimer’s disease patients this year.”

Recent Highlights and Accomplishments

Dimebon

• Expect to complete patient enrollment in CONNECTION, a confirmatory, pivotal Phase 3 trial in patients with mild-to-moderate Alzheimer’s disease, in June.

• Initiated the Phase 3 CONCERT trial in patients with mild-to-moderate Alzheimer’s disease; the 12-month clinical trial is designed to evaluate the efficacy of Dimebon when added to ongoing treatment with donepezil (Aricept^®), the leading Alzheimer’s disease medication worldwide, and builds on data from a small-scale safety and tolerability trial of Dimebon added to donepezil, which found the combination to be well tolerated.

• Completed a multicenter, randomized, double-blind, placebo-controlled Phase 1 study to evaluate the safety and tolerability of Dimebon given to Alzheimer’s disease patients who currently are on a stable dose and regimen of memantine (Namenda^®) or memantine plus donepezil. The study showed that these combinations were well tolerated.

• In addition to the CONNECTION and CONCERT trials and a Phase 3 safety study already underway, we and Pfizer plan to initiate two additional Phase 3 studies in 2009 that will evaluate Dimebon in a total of approximately 1,100 patients with moderate-to-severe Alzheimer’s disease.

• Expect to initiate a Phase 3 trial this year to evaluate Dimebon’s potential benefits on cognition in patients with mild-to-moderate Huntington’s disease.

• Presented posters featuring Dimebon at the 61^st American Academy of Neurology Annual Meeting in Seattle on April 29 and 30, including a poster entitled “Estimating Disease-Modifying Effects Using a Staggered Start Approach and a Natural History Staggered Start (NHSS) Approach: Preliminary Results from a 12-Month Study of Dimebon and a 6-Month Open-Label Period.”

• Presented a poster at the American Geriatrics Society meeting in Chicago on May 1.

MDV3100

• Received written permission from the U.S. Food and Drug Administration to initiate a pivotal Phase 3 trial of MDV3100 in castration-resistant prostate cancer in men who were previously treated with docetaxel-based chemotherapy; the primary endpoint of this randomized, placebo-controlled, double-blind, multinational trial will be overall survival.

• Announced publication of an article in the May 8 issue ofScience,presenting the discovery, novel mechanism of action and potent anti-androgen properties of MDV3100.

• Conducted a podium presentation featuring MDV3100 at the 2009 American Urological Association Annual Meeting in Chicago on April 26.

• Received acceptance by the American Society of Clinical Oncology (ASCO) of an abstract, entitled “Antitumor activity of MDV3100 in a Phase 1-2 study of castration-resistant prostate cancer (CRPC),” for oral presentation at the 2009 ASCO Annual Meeting on May 30 at 4:15 p.m. Eastern Time.

• MDV3100 abstract selected by ASCO for inclusion in the Best of ASCO^® program, an educational initiative covering highlights from the ASCO Annual Meeting to increase global access to cutting-edge science.

First Quarter 2009 Financial Results

Revenue for the first quarter of 2009 was $16.3 million, consisting of partial recognition of the non-refundable up-front payment of $225.0 million received from Pfizer in October 2008. The up-front payment was recorded as deferred revenue upon receipt and is being recognized on a straight-line basis over the estimated performance period of the Company’s obligations under its collaboration agreement with Pfizer, which the Company presently expects to complete in the first quarter of 2012.

For the three months ended March 31, 2009, total operating expenses were $22.1 million, compared with total operating expenses of $15.9 million for the same period in 2008. These figures include non-cash stock-based compensation expense of $2.6 million in the quarter ended March 31, 2009, compared with $2.1 million for the same period in 2008.

Beginning October 21, 2008, Pfizer became responsible for 60 percent of all Dimebon-related development and commercialization costs in the U.S., and 100 percent of such costs outside the U.S. The parties are making quarterly true-up payments as necessary to ensure that each bears its applicable share of costs. For the first quarter of 2009, the true-up payment payable to Medivation was $5.8 million. Medivation presents these cost-sharing true-up payments in the applicable expense line of its statement of operations.

Medivation reported a net loss for the quarter ended March 31, 2009, of $5.6 million, or $0.19 per share, compared with a net loss of $15.5 million, or $0.54 per share, for the same period in 2008.
