XTANDI is an oral, once-daily androgen receptor inhibitor. Medivation is headquartered in San Francisco, California, and it began operations in December 2004 with the acquisition of Medivation Neurology, Inc. The current CEO is David Hung.

Class action lawsuit
On March 3, 2010, Medivation's stock dropped $27.15 per share to close at $13.10, a 67% one-day decline on volume of 45 million shares. In response, a security fraud class-action lawsuit was initiatied by Izard Nobel LLP, alleging that Medivation made false and misleading statements regarding the effectiveness of Dimebon as a treatment for Alzheimer's disease, before being revealed that it did not meet primary and secondary goals in a Phase 3 trial for patients with mild to moderate Alzheimer's disease.

The counsel for the case was Bernstein Liebhard and the lead plaintiffs were initially David Applestein then Catoosa Fund, LP. On March 22, 2012, the case was dismissed with prejudice. The plaintiffs appealed the dismissal in the Ninth Circuit Court of Appeals. The Ninth Circuit granted oral argument which will be held on Friday, January 17, 2014.
