A Study of Pembrolizumab (MK-3475) Versus Paclitaxel, Docetaxel, or Vinflunine for Participants With Advanced Urothelial Cancer (MK-3475-045/KEYNOTE-045)

Summary

Participants with metastatic or locally advanced/unresectable urothelial cancer that has recurred or progressed following platinum-based chemotherapy will be randomly assigned to receive Investigator's choice of paclitaxel, docetaxel, or vinflunine (Control), or pembrolizumab. The primary study hypotheses are that pembrolizumab will prolong Overall Survival (OS) and Progression-free Survival (PFS) compared to paclitaxel, docetaxel, or vinflunine.
