Study Arms:
- A: Cobimetinib (Type: EXPERIMENTAL): Participants will receive the standard single-agent cobimetinib dose of 60 milligrams (mg) (3 tablets of 20 mg each) orally (PO) daily on Days 1-21 of each 28-day cycle until disease progression. Upon progression, participants will be allowed to receive treatment with cobimetinib and atezolizumab at the recommended Phase II dose of cobimetinib 60 mg PO on Days 1-21 plus atezolizumab intravenous (IV) infusion at a fixed dose of 840 mg on Day 1 and Day 15 of each 28-day cycle. Treatment will continue until the participant has disease progression, unacceptable toxicity, death, participant or physician decision to withdraw, or pregnancy, whichever occurs first.
- B: Cobimetinib + Venetoclax (Type: EXPERIMENTAL): Participants will receive cobimetinib PO daily on Days 1-21 of each 28-day cycle plus venetoclax PO daily on Days 1-28 of each 28-day cycle, at the dose level identified in the safety run-in phase. Treatment will continue until the participant has disease progression, unacceptable toxicity, death, participant or physician decision to withdraw, or pregnancy, whichever occurs first.
- C: Cobimetinib + Venetoclax + Atezolizumab (Type: EXPERIMENTAL): Participants will receive cobimetinib PO daily on Days 1-21 of each 28-day cycle plus venetoclax PO daily on Days 1-28 of each 28-day cycle, at the dose level identified in the safety run-in phase plus atezolizumab IV infusion at a fixed dose of 840 mg on Day 1 and Day 15 of each 28-day cycle. Treatment will continue until the participant has disease progression, unacceptable toxicity, death, participant or physician decision to withdraw, or pregnancy, whichever occurs first.
- Safety Run-In: Cobimetinib + Venetoclax (Type: EXPERIMENTAL): Participants will receive cobimetinib (on Day 1-21) plus venetoclax (on Day 1-28) at escalated doses, in 28-day cycles, to identify the dose level with acceptable safety.
- Safety Run-In: Cobimetinib + Venetoclax + Atezolizumab (Type: EXPERIMENTAL): Participants will receive cobimetinib (on Day 1-21) plus venetoclax (on Day 1-28) at escalated doses and atezolizumab (on Day 1 and Day 15) at a fixed dose of 840 mg IV, in 28-day cycles, to identify the dose level with acceptable safety.
