Description

Summary

This is a Phase III, double-blinded, placebo-controlled, randomized, multicenter study designed to evaluate the efficacy, safety, and pharmacokinetics of atezolizumab + cobimetinib + vemurafenib compared with placebo + cobimetinib + vemurafenib in patients with previously untreated BRAFv600 mutation-positive metastatic or unresectable locally advanced melanoma.

Official Title
