A Randomized Phase II Study of Anti-PD1 Antibody [MK-3475 (Pembrolizumab)] Alone Versus Anti-PD1 Antibody Plus Stereotactic Body Radiation Therapy in Advanced Merkel Cell Carcinoma

Study Overview

This randomized phase II trial studies how well pembrolizumab with or without stereotactic body radiation therapy works in treating patients with merkel cell cancer that has spread to other places in the body.
