Study Summary

The purpose of this study is to describe the rate of 3-year progression free survival in men with recurrent PSA-only disease after prostatectomy, who receive combined apalutamide (ARN-509) and standard ADT with salvage radiation therapy followed by docetaxel, ADT, and apalutamide, AND who have had testosterone recovery to \>100 ng/dl at 36 months. The hypothesis is that AR inhibition with apalutamide added to standard salvage external beam radiation with androgen deprivation therapy, as well as the addition of 6 cycles of docetaxel, will further prolong progression free survival.

Primary Outcome

The percentage of subjects with testosterone \>100 ng/dl at 36 months post-Cycle 1 Day 1 without one or more of the following: Serum PSA value of 0.2 ng/mL or more above the post-radiotherapy PSA nadir and confirmed (at least) 4 weeks later by a second PSA measurement higher than the first by any amount; Continued rise in the PSA level following study treatment if no nadir is experienced, defined as 2 rising values greater than the baseline PSA and separated by at least 4 weeks; Evidence of clin
