Brief Summary:
The purpose of this study is to determine the safety, tolerability, and objective response rate (ORR) of pembrolizumab (MK-3475) in Chinese participants with locally advanced or metastatic melanoma, with disease progression following first line chemotherapy or targeted therapy. ORR will be based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1).
