This clinical trial is focused on studying treatments for Muscle-Invasive Bladder Cancer, a type of cancer that affects the bladder muscle. The study is comparing different treatment approaches to see which is more effective. One group of participants will receive standard chemotherapy, which involves using drugs to kill cancer cells. The chemotherapy drugs being used in this study include gemcitabine hydrochloride and cisplatin. Another group will receive chemotherapy combined with a drug called nivolumab, which is an immunotherapy that helps the immune system fight cancer. Some participants may also receive an additional drug known as BMS-986205, which is being tested for its potential to enhance the effects of nivolumab.
The purpose of the study is to determine if adding nivolumab, with or without BMS-986205, to chemotherapy before surgery can improve outcomes for patients with muscle-invasive bladder cancer. Participants will be randomly assigned to one of the treatment groups. After receiving the initial treatment, participants will undergo surgery to remove the bladder cancer. Following surgery, some participants will continue to receive nivolumab, with or without BMS-986205, to see if it helps prevent the cancer from returning.
The study will last for a period of time, during which participants will receive their assigned treatments and be monitored for any changes in their condition. The researchers will be looking at various outcomes, such as the rate of complete response to the treatment, which means no signs of cancer are found after treatment, and event-free survival, which refers to the length of time participants remain free from cancer-related events. The study will also track overall survival and any side effects or adverse events that may occur during the trial.
