What was measured

OS at 1- and 2-year landmark timepoints in Teff-high WT population and ITT-WT population.

Analysis population: Teff-high WT population is defined as the Teff-high population excluding patients with an activating EGFR mutation or ALK translocation. ITT-WT population is defined as the ITT population excluding patients with an activating EGFR mutation or ALK translocation.

Groups in this outcome

Arm A (Atezolizumab+Paclitaxel+Carboplatin)

Participants received intravenous (IV) infusion of atezolizumab on Day 1 of each 21-day cycle followed by IV infusion of paclitaxel and carboplatin on Day 1 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 C (Bevacizumab+Paclitaxel+Carboplatin)

Participants received IV infusion of bevacizumab on Day 1 of each 21-day cycle followed by IV infusion of paclitaxel and carboplatin on Day 1 of each 21-day cycle for 4 or 6 cycles or loss of clinical benefit whichever occurs first, during induction treatment phase. Participants received IV infusion of bevacizumab during maintenance treatment phase until progressive disease, unacceptable toxicity, or death.
