About the AFFIRM Trial
The Phase 3 AFFIRM trial is a randomized, double-blind, placebo-controlled, multinational trial evaluating MDV3100 (160 mg/day) versus placebo in 1,199 men with advanced prostate cancer who were previously treated with docetaxel-based chemotherapy. In November 2011, the Independent Data Monitoring Committee overseeing the AFFIRM trial informed the companies of positive overall survival results from the planned interim analysis and recommended that the study be stopped early and that all patients who received placebo be offered MDV3100. MDV3100 has been granted Fast Track designation by the FDA for the post-chemotherapy indication.
