A Study of Atezolizumab in Combination With Carboplatin Plus (+) Nab-Paclitaxel Compared With Carboplatin+Nab-Paclitaxel in Participants With Stage IV Non-Squamous Non-Small Cell Lung Cancer (NSCLC)

Conditions

• Carcinoma, Non-Squamous Non-Small Cell Lung

Interventions

• Atezolizumab (MPDL3280A), an engineered anti-PD-L1 antibody — DRUG
  Atezolizumab was administered as IV infusion at a dose of 1200 milligrams (mg) on Day 1 of each 21-day cycle. Atezolizumab was administered to participants who were randomized to "Arm A (Atezolizumab + Nab-Paclitaxel + Carboplatin)" and to participants in "Arm B (Nab-Paclitaxel + Carboplatin)" who cross over at progression.
• Carboplatin — DRUG
  Carboplatin was administered at area under the concentration curve (AUC) 6 milligrams per milliliter per minute (mg/mL/min) on Day 1 of each 21-day cycle.
• Nab-Paclitaxel — DRUG
  Nab-paclitaxel was administered as IV infusion at a dose of 100 milligrams per square meter (mg/m\^2) on Days 1, 8, and 15 of each 21-day cycle.
• Pemetrexed — DRUG
  Switch maintenance to pemetrexed can be administered within 6 weeks of Day 1 of the last induction cycle.

Study Details

This randomized Phase III, multicenter, open-label study designed to evaluate the safety and efficacy of atezolizumab (an engineered anti-programmed death-ligand 1 \[PD-L1\] antibody) in combination with carboplatin+nab-paclitaxel compared with treatment with carboplatin+nab-paclitaxel in chemotherapy-naive participants with Stage IV non-squamous NSCLC. Participants were randomized in a 2:1 ratio to Arm A (Atezolizumab+Nab-Paclitaxel+Carboplatin) or Arm B (Nab-Paclitaxel+Carboplatin).

Arms

• Experimental: 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 occurred first during induction treatment phase. Participants received IV infusion of atezolizumab during maintenance treatment phase until loss of clinical benefit.
• Active Comparator: 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 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.

Primary Outcome Measure

Progression-Free Survival (PFS) as Determined by the Investigator Using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) in the ITT-WT Population [ Time Frame: Up to approximately 35 months after first patient enrolled ]
