A Phase II Clinical Trial of Single Agent Pembrolizumab (MK-3475) in Subjects With Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma (HNSCC) Who Have Failed Platinum and Cetuximab

This is a study of single-agent pembrolizumab (MK-3475) in participants with recurrent and/or metastatic head and neck squamous cell carcinoma (HNSCC) who have progressed on platinum-based and cetuximab therapy. The primary study hypothesis is that pembrolizumab will provide a clinically meaningful objective response rate (ORR). With protocol amendment 05 (02-Jan-2018), once study participants have achieved the study objective or the study has ended, participants will be discontinued from this study and enrolled in an extension study to continue protocol-defined assessments and treatment.
