Interventions

  • Cobimetinib — DRUG
    Cobimetinib will be administered at a starting dose of 60 mg by mouth (PO) daily (QD) on Days 1-21 of each 28-day cycle (Stage 1) and PO QD on Days 1-21 (21/7 schedule) at the established dose for the doublet regimen in Stage 1 (Stage 2).
  • Niraparib — DRUG
    Niraparib will be administered at a starting dose of 200 mg of niraparib PO QD on Days 1-28 of each 28-day cycle (Stage 1) and PO QD on Days 1-28 of each 28-day cycle at the established dose for the doublet regimen in Stage 1 (Stage 2).
  • Atezolizumab — DRUG
    Atezolizumab will be administered by IV infusion at the fixed dose of 840 mg on Days 1 and 15 (+/-3 days) of each 28-day cycle (Stages 1 and 2).

Study Details

The study will include a safety run-in phase (Stage 1) and a randomization phase (Stage 2). The purpose of Stage 1 is to evaluate the safety of cobimetinib when administered in combination with niraparib (Cohort 1) and cobimetinib with niraparib plus atezolizumab (Cohort 2). Stage 1 will enable patient enrollment in the randomized phase of the study (Stage 2) with both regimens at the recommended dose levels from Stage 1. Stage 2 is a randomized, dose-expansion phase, evaluating clinical outcomes in patients with advanced platinum-sensitive ovarian cancer. All patients will continue to receive study treatment until disease progression (according to "Response Evaluation Criteria in Solid Tumors" (RECIST), Version 1.1, unacceptable toxicity, death, or patient or investigator decision to withdraw, whichever occurs first.
