This clinical trial is focused on studying the treatment of cutaneous malignant melanoma, a type of skin cancer. The study will use two medications: KEYTRUDA (pembrolizumab) and OPDIVO (nivolumab). Both medications are given as a solution for infusion, which means they are administered directly into the bloodstream through a vein.
The purpose of the study is to determine if a shorter duration of treatment with these medications is as effective as a longer one. Specifically, it will compare the effects of 6 months of treatment to 12 months of treatment in patients who have undergone radical surgery for high-risk melanoma. The study aims to see if the shorter treatment duration can provide the same benefits in preventing the cancer from returning or spreading.
Participants in the study will receive either KEYTRUDA or OPDIVO after their surgery. The study will monitor the patients over time to assess their health and the effectiveness of the treatment. The main focus will be on how long patients remain free from distant metastases, which are cancer cells that have spread to other parts of the body, and how long they remain free from any signs of cancer returning. Additionally, the study will look at the overall survival of the patients, which refers to the length of time they live after starting the treatment.
