According to the results of a large phase I study, a new drug called MK-3475 may benefit people with melanoma that has spread to other parts of the body. MK-3475 blocks the function of a protein called PD-1 (programmed death-1) found on T-cells, a type of white blood cell that directly helps fight disease. Because PD-1 keeps the immune system from destroying cancer cells, stopping PD-1 from working allows the immune system to better eliminate melanoma.
