Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Cobimetinib
Treatment: Drugs - Atezolizumab
Treatment: Drugs - Pembrolizumab

Experimental: Cobimetinib and Atezolizumab - Participants will receive 60 mg of cobimetinib orally from Days 1 to 21 along with 840 mg of atezolizumab by intravenous (IV) infusion on Days 1 and 15 of each 28-day cycle until investigator-determined disease progression, unacceptable toxicity, death, patient or physician decision to withdraw, or pregnancy, whichever occurs first. There will be no cobimetinib administration for 7 days (Days 22-28) in each cycle.

Active comparator: Pembrolizumab - Participants will receive 200 mg of pembrolizumab administered by IV infusion every 3 weeks (Q3W) until investigator-determined disease progression, unacceptable toxicity, death, patient or physician decision to withdraw, or pregnancy, whichever occurs first.


Treatment: Drugs: Cobimetinib
Cobimetinib 60 mg tablets orally once daily on a 21 days on, 7 days off schedule.

Treatment: Drugs: Atezolizumab
Atezolizumab 840 mg as IV infusion once in every 2 weeks.

Treatment: Drugs: Pembrolizumab
Pembrolizumab 200 mg as IV infusion once in every 3 weeks.
