MEDIVATION REPORTS FOURTH QUARTER AND YEAR-END 2010 FINANCIAL

RESULTS AND PROVIDES CORPORATE UPDATE

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

San Francisco(March 16, 2011) — Medivation, Inc. (Nasdaq: MDVN) today provided a corporate update and reported its financial results for the year ended December 31, 2010.

“We are pleased with the progress we made with our MDV3100 and dimebon programs in 2010, and we look forward to reporting Phase 3 data from each of these programs in the near-term. With regard to dimebon, we expect to report top-line data from our Phase 3 Huntington disease trial in the first half of this year, with top-line data from our Phase 3 mild-to-moderate Alzheimer’s disease trial expected to follow in the first half of 2012. And with MDV3100, we expect to report top-line data from our Phase 3 AFFIRM trial in advanced prostate cancer in 2012, although those data could come in 2011 if an interim analysis is conducted,” said David Hung, MD, president and chief executive officer of Medivation. “Our company also remains in a strong financial position, with more than $200 million in cash at December 31, 2010 and strong corporate partnerships for each of our programs that provide substantial cost-sharing benefits. Based on our current budget, we believe our existing cash is adequate to fund our currently planned operations beyond the end of 2012, by which time we expect to have completed and reported top-line data from all three of our Phase 3 programs.”

Recent Accomplishments and Anticipated Milestones

MDV3100

• Completed patient enrollment in the Phase 3 AFFIRM trial in November 2010. This trial is evaluating MDV3100 in men with advanced prostate cancer who have previously been treated with docetaxel-based chemotherapy. Top-line data are expected in 2012, although they could be reported in 2011 if an interim analysis is conducted.

• Announced positive, new, long-term follow-up data from the Phase 1-2 trial of MDV3100 in patients with advanced prostate cancer showing that MDV3100 continues to demonstrate durable antitumor activity as evaluated by median times to prostate-specific antigen (PSA) progression and radiographic progression. These findings confirm the initial Phase 1-2 results published inThe Lancet, in which MDV3100 consistently demonstrated anti-tumor activity in both chemotherapy-naïve and post-chemotherapy patients across endpoints, as evaluated by PSA levels, radiographic findings and circulating tumor cell (CTC) counts.

• Continued to enroll patients in the Phase 3 PREVAIL trial of MDV3100 in men with advanced prostate cancer who have not yet received chemotherapy. The trial is expected to enroll approximately 1,700 patients globally.

• On track to initiate two new Phase 2 trials to explore the potential benefit of MDV3100 in earlier-stage patient populations – a Phase 2 trial comparing MDV3100 with bicalutamide, a commonly used anti-androgen, in the treatment of advanced prostate cancer patients who have progressed following medical or surgical castration; and a Phase 2 monotherapy trial in advanced prostate cancer patients who have not yet been treated with any hormonal therapy.

• Began clinical development of MDV3100 in Japan, with the initiation of patient dosing in a Phase 1-2 clinical study.

Dimebon (latrepirdine)

• On track to report top-line results from the HORIZON trial in the first half of 2011. This six-month Phase 3 trial is evaluating the potential benefits of dimebon on cognition and global function in patients with Huntington disease.

• Completed patient enrollment in the CONCERT trial in November 2010; on track to report top-line results in the first half of 2012. This 12-month Phase 3 clinical trial in patients with mild-to-moderate Alzheimer’s disease is evaluating the potential efficacy of dimebon when added to ongoing treatment with donepezil.

Corporate

• Received a $10 million milestone payment from Astellas in the fourth quarter of 2010 for the initiation of our Phase 3 PREVAIL trial of MDV3100 in chemotherapy-naïve advanced prostate cancer patients.

Fourth Quarter and Year-End 2010 Financial Results

Revenue for the year ended December 31, 2010, was $62.5 million, consisting of partial recognition of the non-refundable up-front and development milestone payments to date from the Company’s corporate partners Pfizer and Astellas. These payments were recorded as deferred revenue upon receipt and are being recognized as revenue on a straight-line basis over the estimated performance period of the Company’s obligations under the applicable collaboration agreement.

For the quarter and year ended December 31, 2010, total operating expenses were $17.5 million and $95.2 million, respectively, compared with total operating expenses of $42.9 million and $116.7 million, respectively, for the same periods in 2009. The year-end figures include non-cash stock-based compensation expense of $13.5 million in 2010 compared with $10.7 million in 2009.

Medivation reported a net loss for the quarter ended December 31, 2010, of $3.9 million, or $0.11 per share, compared with a net loss of $26.2 million, or $0.78 per share, for the same period in 2009. For the year ended December 31, 2010, the net loss was $34.0 million, or $0.99 per share, compared with a net loss of $54.8 million, or $1.71 per share, for the same period in 2009.

Cash, cash equivalents and short-term investments at December 31, 2010, totaled $207.8 million, compared with $278.2 million at December 31, 2009.

2011 Financial Outlook

Medivation currently expects total operating expenses for 2011, net of cost-sharing payments from Pfizer and Astellas, to be between $100.0 and $110.0 million. This forecast includes approximately $12.0 million of non-cash stock-based compensation expense.

Medivation expects that its existing cash resources are adequate to fund currently planned operations beyond the end of 2012. By the end of 2012, the Company expects to have completed and reported top-line data from the Phase 3 AFFIRM trial of MDV3100 in advanced prostate cancer patients who have failed chemotherapy, the Phase 3 HORIZON trial of dimebon in Huntington disease, and the Phase 3 CONCERT trial of dimebon in mild-to-moderate Alzheimer’s disease.
