Arms & Interventions
Arm A: Atezolizumab + Paclitaxel + Carboplatin
The induction phase of the study will consist of four or six cycles; atezolizumab, paclitaxel, and carboplatin will be administered on Day 1 of each 21-day cycle. The Day 1 order of drug administration is as follows: atezolizumab, then paclitaxel, then carboplatin. Participants who experience no further clinical benefit at any time during the induction phase will discontinue all study treatments. In the absence of the above criteria, after the 4- or 6-cycle induction phase, participants will begin maintenance therapy with atezolizumab. Atezolizumab will be continued as long as there is a clinical benefit to the participant.
