A Phase 3 Randomized Study of Cystectomy plus Perioperative Pembrolizumab versus Cystectomy Alone in Cisplatin-ineligible Participants with Muscle invasive Bladder Cancer (KEYNOTE-905)


General Information

Age Group




Protocol Number


Background Information

The purpose of this study is to see if pembrolizumab before and after surgery is more effective than surgery alone in patients with muscle-invasive bladder cancer (MIBC). This will be measured by tissue samples that are taken during surgery as well as imaging performed at different time points. The study will test the safety of the study drug, pembrolizumab given before and after surgery, and see how well the body handles pembrolizumab before and after surgery. The study will help determine if pembrolizumab and surgery, compared to surgery alone, helps patients have a better quality of life and helps patients live longer.
