In Brief

A Phase 3 clinical trial evaluating Pembrolizumab/Vibostolimab and Pembrolizumab for Melanoma. Completed, enrolled 1,594 participants across 205 sites in 26 countries.

Detailed Summary

The primary purpose of this study is to compare pembrolizumab/vibostolimab to pembrolizumab with respect to recurrence-free survival (RFS). The primary hypothesis is that pembrolizumab/vibostolimab is superior to pembrolizumab with respect to RFS as assessed by the investigator in participants with high-risk resected Stage IIB, IIC, III and IV melanoma.
