What was measured

An AE is any untoward medical occurrence in a participant when administered a pharmaceutical product regardless of the causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom/disease temporally associated with the use of an investigational product, whether or not considered related to the investigational product. A SAE is any significant hazard, contraindication, side effect that is fatal or life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is medically significant or requires intervention to prevent one or other of the outcomes listed above. All AEs were reported until 30 days and SAEs until 90 days after the final dose of study treatment or until initiation of subsequent anti-cancer therapy, whichever occurred first.

Analysis population: Safety population included all participants who received any amount of any atezolizumab, cobimetinib, or vemurafenib. 26 were included in the placebo+cobi+vem arm for safety evaluation (22 participants in atezo+cobi+vem arm stopped run-in treatment \& didn't received atezo \& 4 in atezo+cobi+vem arm completed the run-in treatment but did not receive atezo). During the study, 2 participants in placebo+cobi+vem arm received atezo \& were considered in the atezo+cobi+vem arm for safety analysis.

Groups in this outcome

Arm A: Pbo + Cobi + Vem

Participants received vemurafenib, 960 mg (four, 240 mg tablets), PO, BID along with cobimetinib, 60 mg (three, 20 mg tablets) PO, QD on Days 1 to 21 only followed by vemurafenib 960 mg (four, 240 mg tablets), PO, BID on Days 22 to 28 during the 28 day run-in period. During triple combination period (Cycle 1 onwards), participants received atezolizumab matching placebo as IV infusion on Days 1 and 15, cobimetinib, 60 mg (three, 20 mg tablets) PO, QD, on Days 1 to 21 and vemurafenib 960 mg (four, 240 mg tablets) PO, BID on Days 1 to 28. Study treatment was continued until investigator determined PD, death, unacceptable toxicity, withdrawal of consent, or pregnancy, whichever occurred first.

Arm B: Atezo + Cobi + Vem

Participants received vemurafenib, 960 mg (four, 240 mg tablets) PO, BID along with cobimetinib 60 mg (three, 20 mg tablets) PO, QD on Days 1 to 21 only followed by vemurafenib 720 mg (three, 240 mg tablets) PO, BID and vemurafenib matching placebo, PO, BID on Days 22 to 28 during the 28 day run-in period. During triple combination period (Cycle 1 onwards), participants received atezolizumab 840 mg as IV infusion on Days 1 and 15, cobimetinib, 60 mg (three, 20 mg tablets) PO, QD, on Days 1 to 21, vemurafenib 720 mg (three, 240 mg tablets) PO BID on Days 1 to 28, and vemurafenib placebo (1 tablet) PO BID on Days 1 to 28. Study treatment was continued until investigator determined PD, death, unacceptable toxicity, withdrawal of consent, or pregnancy, whichever occurred first.
