OS in Arm B Versus Arm C in Teff High-WT Population, Teff High Population, and ITT Population

A Study of Atezolizumab in Combination With Carboplatin Plus (+) Paclitaxel With or Without Bevacizumab Compared With Carboplatin+Paclitaxel+Bevacizumab in Participants With Stage IV Non-Squamous Non-Small Cell Lung Cancer (NSCLC) · Source last updated 2021-09-23

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: MEDIAN
Unit: Months
Interval / dispersion: 95% Confidence Interval
Time frame: Baseline until death (up to approximately 34 months)

Analysis population: Teff-high WT population, defined as the Teff-high population excluding patients with activating EGFR mutation or ALK translocation. Teff-high population, defined as participants in the ITT population with Teff signature expression \>=-1.91. ITT population, defined as all randomized patients, regardless of receipt of the assigned treatment.

Groups in this outcome

Arm B (Atezolizumab+Bevacizumab+Paclitaxel + Carboplatin)

Participants received IV infusion of atezolizumab and 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 until loss of clinical benefit whichever occurs first, during induction treatment phase. Participants received IV infusion of atezolizumab until loss of clinical benefit and bevacizumab until progressive disease, unacceptable toxicity, or death during maintenance treatment phase.

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.
