Summary

This study tests a drug called pembrolizumab in 40 men with advanced prostate cancer that has stopped responding to hormone therapy. The drug helps the immune system attack cancer cells. The study focuses on men whose tumors have specific genetic changes. The goal is to see if the drug can shrink tumors or slow the disease, but it is not a cure.
