The purpose of this phase 3 study is to assess the safety and efficacy of enzalutamide (a newer antiandrogen agent) in patients with non metastatic prostate cancer.

The study will assess primarily, the time to delay metastatic disease. Secondary outcomes include assessment of improved overall survival, reduction in pain requirements, need for other treatments, PSA change and overall quality of life.
