Trial Title: 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)

Study Design Characteristics:

Study Arms:
- Arm A (Atezolizumab+Paclitaxel+Carboplatin) (Type: EXPERIMENTAL): 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 B (Atezolizumab+Bevacizumab+Paclitaxel + Carboplatin) (Type: EXPERIMENTAL): 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) (Type: ACTIVE_COMPARATOR): 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.
