Clinical Trial Summary

This study will assess whether post-surgery therapy with pembrolizumab improves recurrence-free survival (RFS) as compared to placebo for high-risk participants with melanoma (Stage IIIA [> 1 mm metastasis], IIIB and IIIC). The study will also assess whether pembrolizumab improves RFS versus placebo in the subgroup of participants with programmed cell death-ligand 1 (PD-L1)-positive tumor expression. Participants will be stratified for stage of disease and region and then will be randomly assigned to receive either pembrolizumab or placebo as post-surgery therapy in Part 1. In Part 2, participants who experience a disease recurrence are eligible for pembrolizumab treatment (if treated with placebo in Part 1) or pembrolizumab rechallenge (if treated with pembrolizumab in Part 1). Participants deriving benefit from pembrolizumab will be given the opportunity to transfer to a pembrolizumab extension study, if available, upon study closure, and will be monitored following the standard of assessments of the pembrolizumab extension study.
