Enzalutamide in First Line Androgen Deprivation Therapy for Metastatic Prostate Cancer

Summary

The purpose of this study is to determine the effectiveness of enzalutamide, versus a conventional non-steroidal anti androgen (NSAA), when combined with a luteinizing hormone releasing hormone analog (LHRHA) or surgical castration, as first line androgen deprivation therapy (ADT) for newly diagnosed metastatic prostate cancer.
