The Company And Summary Of Significant Accounting Policies
The Company And Summary Of Significant Accounting Policies	NOTE 1 — THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES *The Company* Medivation, Inc. (the "Company") 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. The Company's product candidates in clinical development are MDV3100, which is in Phase 3 development for the treatment of advanced prostate cancer, and dimebon (latrepirdine), which is in Phase 3 development for the treatment of mild-to-moderate Alzheimer's disease. The Company's MDV3100 program is partnered with Astellas Pharma Inc., or Astellas, and its dimebon program is partnered with Pfizer Inc., or Pfizer. In October 2009, the Company entered into a collaboration agreement with Astellas. Under the terms of the agreement, the Company and Astellas agreed to develop and commercialize MDV3100 for the treatment of prostate cancer. The Company and Astellas share equally the costs and expenses of developing and commercializing MDV3100 for the United States market, except that development costs for studies useful in both the United States market and either Europe or Japan are shared two-thirds by Astellas and one-third by the Company. The Company and Astellas will share equally profits (or losses) resulting from commercialization of MDV3100 in the United States. Outside the United States, Astellas will bear all development and commercialization costs and will pay the Company tiered double-digit royalties on aggregate net sales of MDV3100. In September 2008, the Company announced a collaboration agreement with Pfizer, which became effective in October 2008. Under the terms of the agreement, the Company and Pfizer agreed to develop and commercialize dimebon for the treatment of Alzheimer's disease and Huntington disease. The Company and Pfizer share the costs and expenses of developing and commercializing dimebon for the United States market on a 60% Pfizer/40% Medivation basis, and will share profits (or losses) resulting from commercialization of dimebon in the United States in the same proportions. Outside the United States, Pfizer will bear all development and commercialization costs and will pay the Company tiered royalties on aggregate net sales of dimebon. The first two Phase 3 clinical studies of dimebon that the Company has completed under its collaboration agreement with Pfizer were both negative. In March 2010, the Company reported negative top-line results from its 598-patient Phase 3 CONNECTION trial of dimebon in patients with mild-to-moderate Alzheimer's disease, and in April 2011 the Company reported negative top-line results from its 403-patient Phase 3 HORIZON trial of dimebon in patients with Huntington disease. Dimebon failed to show a statistically significant benefit over placebo on any of the primary or secondary endpoints in both the CONNECTION and HORIZON trials, and thus did not meet any of either study's efficacy endpoints. Due to the negative results in the CONNECTION trial, Pfizer has the right to terminate the collaboration agreement with the Company at any time. Due to the negative results in the HORIZON trial, the Company and Pfizer discontinued development of dimebon for Huntington disease in April 2011. The Company has funded its operations primarily through private and public offerings of its common stock, and from the up-front, development milestone and cost-sharing payments from its collaboration agreements with Astellas and Pfizer. As of June 30, 2011, the Company had an accumulated deficit of $229.4 million and it expects to incur substantial additional losses for the foreseeable future as it continues to finance clinical and preclinical studies of its existing and potential future product candidates and its corporate overhead costs. *Basis of Presentation* The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.

In May 2011, the FASB amended ASC 820, "Fair Value Measurement." This amendment is intended to result in convergence between U.S. GAAP and International Financial Reporting Standards ("IFRS") requirements for measurement of and disclosures about fair value. This guidance clarifies the application of existing fair value measurements and disclosures, and changes certain principles or requirements for fair value measurements and disclosures. The amendment will be effective for the Company in the second quarter of fiscal year 2012. The Company is currently assessing the potential impact, if any, this amendment may have on its consolidated financial position, results of operations and cash flows.
