Brief 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).

Outcome Measures
Primary Outcomes (2)
Part 1: Percentage of Participants With Recurrence-Free Survival (RFS) At 6 Months Among All Participants
RFS was defined as the time between the date of randomization and the date of first melanoma recurrence (local, regional, distant metastasis) or death (whatever the cause), whichever occurred first. For participants who remained alive and whose disease had not recurred, RFS was censored on the date of last visit/contact with disease assessments. The percentage of participants with RFS at Month 6 was reported for all participants in both treatment arms of Part 1.
6 months
Part 1: Percentage of Participants With Recurrence-Free Survival (RFS) At 6 Months Among Participants With PD-L1-positive Tumor Expression
RFS was defined as the time between the date of randomization and the date of first melanoma recurrence (local, regional, distant metastasis) or death (whatever the cause), whichever occurred first. For participants who remained alive and whose disease had not recurred, RFS was censored on the date of last visit/contact with disease assessments. The percentage of participants with RFS at Month 6 was reported for all participants with PD-L1-positive tumors in both treatment arms of Part 1.

Study Arms (2)
Pembrolizumab
EXPERIMENTALIn Part 1, participants receive pembrolizumab 200 mg intravenously (IV) as post-surgery therapy every 3 weeks (Q3W) for up to 1 year. During Part 2, participants with documented recurrence may receive optional re-treatment with pembrolizumab Q3W for up to 2 years or disease progression.
Placebo
PLACEBO COMPARATORIn Part 1, participants receive placebo IV as post-surgery therapy Q3W. During Part 2, participants with documented recurrence who received placebo in Part 1 may receive optional treatment with pembrolizumab Q3W for up to 2 years or disease progression.
Interventions
Pembrolizumab 200 mg administered intravenously (IV) on Day 1 of each 21-day cycle

- Prior treatment with any anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA4) monoclonal antibody or anti-programmed cell death receptor 1 (PD-1), anti-programmed cell death receptor ligand 1 (PD-L1), or anti-programmed cell death receptor ligand 2 (PD-L2) agent, or prior participation in any Merck pembrolizumab clinical trial
- Currently participating and receiving study therapy, or participated in a study of an investigational agent and received study therapy or used an investigation device within 4 weeks of the first dose of study medication
- Pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 120 days after the last dose of study medication
- Participant is or has an immediate family member (e.g., spouse, parent/legal guardian, sibling or child) who is investigational site or Sponsor staff directly involved with this trial without prospective Institutional Review Board approval (by chair or designee) is given
