Primary Objective

The primary goal of this study is to determine whether, in men with post-prostatectomy PSA (prostate specific antigen) recurrences with aggressive disease features, if salvage radiotherapy (SRT) with enhanced androgen deprivation therapy (ADT), consisting of enzalutamide (MDV3100) and a GnRH analog, will improve progression-free survival compared to SRT with standard GnRH analog-based ADT.

Patient Population

Post prostatectomy prostate cancer patients who have had a PSA recurrence and have signs of aggressive disease features, which include Gleason score of 8-10, seminal vesicle invasion, locoregional node involvement at radical prostatectomy.
