A Phase II Clinical Trial to Study the Efficacy and Safety of Pembrolizumab (MK-3475) and Pembrolizumab in Combination with Other Investigational Agents in Subjects with High-risk Non-muscle-Invasive Bladder Cancer (NMIBC) Unresponsive to Bacillus Calmette-Guerin (BCG) Therapy


This trial will evaluate other treatment options for high-risk NMIBC patients who were unresponsive to Bacillus Calmette Guerin (BCG therapy). We are studying two different drugs in combination with pembrolizumab. Participants will receive up to 35 doses of the trial drug and have tumor assessments for about 2 years. This will be followed by treatment tumor assessment for another 3 years for a total trial duration of 5 years.
