Adjuvant Melanoma A091903

Using Nivolumab Alone or With Cabozantinib to Prevent Mucosal Melanoma Return After Surgery.

This phase II trial tests whether nivolumab in combination with cabozantinib works in patients with mucosal melanoma. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It works by blocking the action of an abnormal protein that signals tumor cells to multiply. This helps stop the spread of tumor cells. Giving nivolumab in combination with cabozantinib could prevent cancer from returning.
