What was measured

OR is defined as either a CR or PR as determined by the investigator with the use of RECIST v1.1 for patients with measurable residual disease after primary surgery.

Analysis population: Objective Response Rate (ORR) - evaluable population is defined as primary surgery patients in the PD-L1-Positive subpopulation with measurable disease at baseline.

Groups in this outcome

Placebo With Paclitaxel, Carboplatin and Bevacizumab

Participants in the primary tumor-reductive surgery group received paclitaxel, carboplatin, atezolizumab placebo IV infusion on Day 1 of each 21-day cycle for a total of 6 cycles, and bevacizumab IV infusion starting with Cycle 2 for a total of 5 cycles, followed by maintenance therapy bevacizumab with atezolizumab placebo for a total of 22 cycles of atezolizumab placebo and 21 cycles of bevacizumab. Participants in the neoadjuvant therapy group received paclitaxel, carboplatin and placebo for 6 cycles and bevacizumab for 4 cycles. Interval surgery will occur between cycles 3 and 4. Each cycle is 21 days long. After 6 cycles, participants started maintenance therapy of bevacizumab and placebo for additional 16 cycles.

Atezolizumab With Paclitaxel, Carboplatin and Bevacizumab

Participants in the primary tumor-reductive surgery group received paclitaxel, carboplatin, atezolizumab intravenous (IV) infusion on Day 1 of each 21-day cycle for a total of 6 cycles, and bevacizumab IV infusion starting with Cycle 2 for a total of 5 cycles, followed by maintenance therapy bevacizumab with atezolizumab for a total of 22 cycles of atezolizumab and 21 cycles of bevacizumab. Participants in the neoadjuvant therapy group received paclitaxel, carboplatin and atezolizumab for 6 cycles and bevacizumab for 4 cycles. Interval surgery will occur between cycles 3 and 4. Each cycle is 21 days long. After 6 cycles, participants started maintenance therapy of bevacizumab and atezolizumab for additional 16 cycles.
