What was measured

Cmax is the maximum observed plasma concentration at steady state.

Analysis population: The PK population included participants from Arms B and C who received at least one dose of study medication and for whom at least one evaluable PK sample was collected.

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.

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.
