Testing the Addition of the Immunotherapy Drug, Pembrolizumab, to Radiation Therapy Compared to the Usual Chemotherapy Treatment During Radiation Therapy for Bladder Cancer, the PARRC Trial
Recruiting
This phase II trial compares the use of pembrolizumab and radiation therapy to chemotherapy with cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C and radiation therapy for the treatment of patients with non-muscle invasive bladder cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, gemcitabine, 5-fluorouracil o... Read More
