This clinical trial is focused on studying a type of cancer called urothelial cancer, which affects the urinary system, including the bladder. The trial is specifically for cases where the cancer is advanced and cannot be removed by surgery. The study is investigating the effectiveness of two medications, Nivolumab and Ipilimumab, used together as a maintenance therapy. These medications are given after patients have completed their initial chemotherapy treatment. Nivolumab and Ipilimumab are types of immunotherapy, which means they help the body’s immune system fight cancer.
The purpose of the study is to see if this combination of medications can help delay the progression of the cancer. Patients who participate in the study will receive the medications through an infusion, which is a way of delivering the drugs directly into the bloodstream. The study will monitor patients over a period to see how the cancer responds to the treatment and to check for any side effects. Some patients in the study may receive a placebo, which is a substance with no active medication, to compare the effects of the treatment.
Throughout the study, researchers will collect information on how long patients live without the cancer getting worse, overall survival rates, and any changes in the size of the cancer. They will also look at the quality of life reported by patients using questionnaires. The study aims to provide valuable insights into whether this treatment approach can offer benefits to patients with advanced urothelial cancer.
