Study Summary

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.

Primary Outcome

The safety profiles of Cobimetinib plus Niraparib and Cobimetinib plus Niraparib plus Atezolizumab will be evaluated in terms of number of patients reporting serious and non-serious AEs with severity graded according to National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI - CTCAE v5.0)
