Comparing the Outcome of Immunotherapy-Based Drug Combination Therapy with or without Surgery to Remove the Kidney in Metastatic Kidney Cancer, the PROBE Trial

Trial Status: active

This phase III trial compares standard systemic treatment alone versus standard systemic treatment plus surgery to remove all or part of the affected kidney (cytoreductive nephrectomy) in treating patients with kidney cancer that has spread to other places in the body (metastatic). Standard systemic therapy for this type of cancer is immunotherapy-based combination therapy which may shrink the tumor and stimulate the immune system to attack the cancer. Systemic therapy is a type of treatment when drugs travel through the blood to cells all over the body. Immunotherapy with monoclonal antibodies, such as nivolumab, ipilimumab, pembrolizumab, and avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cytoreductive nephrectomy is a surgical procedure to remove as many cancer cells from the kidney as possible. This study will help determine whether addition of surgery to standard of care systemic therapy is better than systemic therapy alone for the treatment of metastatic kidney cancer.
