Summary:

      This study will assess the safety, tolerability, and efficacy of every-3-week dosing (Q3W) of
      pembrolizumab (MK-3475) in participants with advanced melanoma; participants may receive
      pembrolizumab for up to 2 years if deriving clinical benefit. The primary study hypothesis is
      that treatment with single agent pembrolizumab will result in a clinically meaningful overall
      response rate.
