Pembrolizumab and BCG Solution in Treating Patients with Recurrent Non-muscle-invasive Bladder Cancer
The purpose of this study is to evaluate the efficacy (the effect of drug on tumor) and the tolerability (the effect of drug on the body) of pembrolizumab, when given as a single agent in patients with bladder tumors. Another purpose of the study is to see what tumor characteristics are associated with increased efficacy of the pembrolizumab. Pembrolizumab is an antibody (a human protein that sticks to a part of the tumor and/or immune cells) designed to allow the body’s immune system to work against tumor cells. Pembrolizumab is Food and Drug Administration (FDA) approved for the treatment of advanced melanoma (a type of skin cancer) and some types of lung cancer. It is not yet approved by the United States Food and Drug Administration (USFDA) for bladder cancer, hence it is considered an investigational agent for this disease.

OUTLINE: This is a dose-escalation study of pembrolizumab.
PRE-INDUCTION PHASE: Patients receive pembrolizumab intravesically once on day -14.
INDUCTION PHASE: Patients receive BCG solution intravesically once weekly for 6 weeks at weeks 0-5 and pembrolizumab intravesically every 2 weeks at weeks 0, 2, and 4.
MAINTENANCE PHASE: Beginning 2 weeks after the last dose of BCG solution, patients receive pembrolizumab intravesically every 2 weeks for 12 weeks at weeks 7, 9, 11, 13, 15, and 17 for a total of 6 doses. Patients then receive pembrolizumab intravesically every 4 weeks at weeks 21, 25, 29, 33, 37, 41, 45, and 49 for a total of 8 doses.
After completion of study treatment, patients are followed up every 3 months for 2 years, every 4 months for 2 years, every 6 months for 2 years, and then every 12 months thereafter.
