What was measured

ORR was defined as a stringent complete response (sCR), complete response (CR), very good partial response (VGPR), or partial response (PR) and was analyzed in the safety evaluable population and in the biomarker-selected sub-populations of t(11;14) and RAS mutations.

Analysis population: The safety evaluable population included all participants who received any amount of study drug.

Groups in this outcome

Safety Run-In: Cobimetinib + Venetoclax

Participants received 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

Participants received 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.

A: Cobimetinib

Participants received 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 were 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 continued until disease progression, unacceptable toxicity, death, participant or physician decision to withdraw, or pregnancy, whichever occurred first.

B: Cobimetinib + Venetoclax

Participants received 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 continued until disease progression, unacceptable toxicity, death, participant or physician decision to withdraw, or pregnancy, whichever occurred first.

C: Cobimetinib + Venetoclax + Atezolizumab

Participants received 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 continued until disease progression, unacceptable toxicity, death, participant or physician decision to withdraw, or pregnancy, whichever occurred first.
