Summary

The purpose of this study is to assess the safety and efficacy of pembrolizumab (MK-3475) combined with lenvatinib (MK-7902/E7080) compared to pembrolizumab alone (with placebo for lenvatinib) as first-line treatment in adults with no prior systemic therapy for their advanced melanoma.

The primary study hypotheses are that: 1) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), and 2) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Overall Survival (OS). For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.
