A Phase 1b Study of Atezolizumab in Combination With Vemurafenib or Vemurafenib Plus Cobimetinib in Participants With BRAFV600-Mutation Positive Metastatic Melanoma
July 20, 2020 updated by: Genentech, Inc.
A Phase Ib, Open-Label Study of The Safety and Pharmacology of Atezolizumab (Anti PD-L1 Antibody) Administered in Combination With Vemurafenib or Vemurafenib Plus Cobimetinib in Patients With BRAFV600-Mutation Positive Metastatic Melanoma
This is an open-label, multicenter, Phase Ib, dose-escalation and cohort-expansion study of atezolizumab (anti-programmed death-ligand 1 [PD-L1] antibody) in combination with vemurafenib or vemurafenib plus cobimetinib in participants with BRAFV600-mutation positive metastatic melanoma.
Enrolled participants may continue treatment until they are no longer experiencing clinical benefit as assessed by the investigator and in alignment with the protocol.
