The purpose of this study is to evaluate the long-term safety and efficacy of pembrolizumab (MK-3475) in participants from previous Merck pembrolizumab-based parent studies who rollover into this extension study. This study will consist of three phases: 1) First Course Phase, 2) Survival Follow-up Phase or 3) Second Course Phase. Each participant will roll-over to this extension study in one of the following three phases, depending on the study phase they were in at the completion of the parent study. Participants who were in the First Course Phase of study treatment in their parent study will enter the First Course Phase of this study and complete up to 35 cycles of study treatment with pembrolizumab or a pembrolizumab-based combination. Participants who were in the Follow-up Phase in the parent study (post-treatment or Survival Follow-up Phase) will enter the Survival Follow-up Phase of this study. Participants who were in the Second Course Phase in their parent study will enter Second Course Phase of this study and complete up to 17 cycles of study treatment with pembrolizumab or a pembrolizumab-based combination.
