Study Arms:
- Arm A (Atezolizumab+Nab-Paclitaxel+Carboplatin) (Type: EXPERIMENTAL): Participants received intravenous (IV) infusion of atezolizumab and carboplatin on Day 1 of each 21-day cycle, and nab-paclitaxel on Days 1, 8, and 15 of each 21-day cycle for 4 or 6 cycles or until loss of clinical benefit whichever occurred first during induction treatment phase. Participants received IV infusion of atezolizumab during maintenance treatment phase until loss of clinical benefit.
- Arm B (Nab-Paclitaxel+Carboplatin) (Type: ACTIVE_COMPARATOR): Participants received IV infusion of carboplatin on Day 1 and nab-paclitaxel on Days 1, 8, and 15 of each 21-day cycle for 4 or 6 cycles or until disease progression whichever occurred first during induction treatment phase. Participants received best supportive care during maintenance treatment phase. Switch maintenance to pemetrexed was also permitted. Participants who were consented prior to approval of protocol Version 5 were given the option to cross over to receive atezolizumab as monotherapy until disease progression.

Based on this trial design, predict the completion outcome and termination type (if applicable).
