SAN FRANCISCO, July 17 /PRNewswire-FirstCall/ -- Medivation, Inc. (Nasdaq: MDVN) today announced publication of the results of its first Alzheimer's disease pivotal clinical trial of the investigational drug Dimebon in the July 19, 2008 issue of The Lancet. In this double-blind, placebo-controlled trial, patients with mild-to-moderate Alzheimer's disease treated with Dimebon experienced statistically significant improvements compared to placebo in all the key aspects of the disease: memory and thinking, activities of daily living, behavior and overall function.

After both six months and a full year of treatment, Dimebon-treated patients were significantly better than placebo-treated patients on all key aspects of the disease. The benefit on the primary endpoint, the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) at six months, was highly significant (p<0.0001). Patients treated with Dimebon were also significantly improved at six months over baseline on all measures (p=0.005 on ADAS-cog). Dimebon's benefit over placebo continued to increase throughout the 12-month treatment period. At the end of 12 months, Dimebon-treated patients preserved their starting level of function on each measure of Alzheimer's disease.

"In this study, Dimebon improved the clinical course of Alzheimer's disease, which is important given that the natural course is progressive deterioration over time," said Rachelle Doody, M.D., Ph.D., lead author and the Effie Marie Cain Chair in Alzheimer's Disease Research at
