After observing benefits in OS and radiographic PFS (co-primary endpoints), the IDMC for Medivation (MDVN +3.7%) and Astellas Pharma's (ALPMF +0.9%) Phase 3 PREVAIL trial of enzalutamide in metastatic prostate cancer recommends "the study be stopped and patients treated with placebo be offered enzalutamide."

Enzalutamide reduced the risk of death by 30% (Hazard Ratio .70), and patients saw an 81% reduction in risk of radiographic progression or death (Hazard Ratio 0.19).

Here's Dr. Tomasz Beer, professor of medicine and deputy director of the Knight Cancer Institute: "To my knowledge, the benefits in overall survival and radiographic progression-free survival reported in today's PREVAIL trial results are unprecedented in this patient population." (PR)
