Purpose

This phase II trial studies the effect of adding pembrolizumab to gemcitabine in treating patients with non-muscle invasive bladder cancer whose cancer does not respond to Bacillus Calmette-Guerin (BCG) treatment. Chemotherapy drugs, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the patient's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Adding pembrolizumab to gemcitabine may delay the return of BCG-unresponsive bladder cancer for longer period compared to gemcitabine alone.

      Treatment (pembrolizumab, gemcitabine hydrochloride)

      		INDUCTION: Patients receive pembrolizumab IV over 25-40 minutes on day 1 of cycles 1-4. Patients also receive gemcitabine hydrochloride intravesically on days 1, 8 and 15 of cycles 1 and 2. Treatment repeats every 3 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. MAINTENANCE: Beginning cycle 5, patients with no evidence of disease after induction receive pembrolizumab IV over 25-40 minutes and gemcitabine intravesically on day 1. Treatment repeats every 3 weeks for 12 cycles in the absence of disease progression or unacceptable toxicity.
