The purpose of this study is to test the safety of the study drug, pembrolizumab in combination with a hormone drug (enzalutamide) for prostate cancer. Other aims of the study are to see how well your body handles pembrolizumab compared to placebo (a look-alike with no active ingredients) in combination with enzalutamide, see how well pembrolizumab compared to placebo works in combination enzalutamide, see if pembrolizumab in combination with enzalutamide helps patients have a better quality of life and see if pembrolizumab in combination with enzalutamide helps patients live longer.
