Other interventions - Atezolizumab
Treatment: Drugs - Cobimetinib
Other interventions - Atezolizumab
Other interventions - Atezolizumab

Experimental: Cohort A - Participants with disease progression on or after treatment with an anti-PD-1 agent will receive cobimetinib and atezolizumab treatment during 28-day cycles.

Summary
Brief summary
This study will evaluate the preliminary efficacy, safety, and pharmacokinetics of
cobimetinib and atezolizumab in participants with advanced BRAF V600-wild type (WT),
metastatic, or unresectable locally advanced melanoma who have progressed on prior anti-PD-1
therapy. In addition, this study will evaluate the efficacy, safety, and pharmacokinetics of
atezolizumab monotherapy in participants with BRAFV600-WT metastatic or unresectable locally
advanced melanoma, who have not been previously treated.
