What was measured

ORR (confirmation not required) is defined as proportion of participants with an objective response, either CR or PR, with the use of RECIST v1.1, as determined by investigator in ITT population, PD-L1 Expression population, and PD-L1 Expression WT population. ITT population was defined as all randomized participants, regardless of receipt of the assigned treatment. PD-L1 expression population is defined as one of the following: PD-L1 IHC TC1/2/3 or IC1/2/3 population, defined as ITT participants with PD-L1 IHC TC1/2/3 or IC1/2/3 expression in baseline tumor tissue; PD-L1 IHC TC2/3 or IC2/3 population, defined as ITT participants with PD-L1 IHC TC2/3 or IC2/3 expression in baseline tumor tissue; PD-L1 IHC TC3 or IC3 population, defined as ITT participants with PD-L1 IHC TC3 or IC3 expression in baseline tumor tissue. PD-L1 expression WT population is defined as PD-L1 expression population excluding participants with an activating EGFR mutation or ALK translocation.

Groups in this outcome

Arm A (Atezolizumab+Nab-Paclitaxel+Carboplatin)

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 occurs 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)

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 occurs first during induction treatment phase. Participants will receive best supportive care during maintenance treatment phase. Switch maintenance to pemetrexed is also permitted. Participants who were consented prior to approval of protocol Version 5 will be given the option to cross over to receive atezolizumab as monotherapy until disease progression.
