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)

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).

Sex

All

Minimum age

18 Years

Inclusion Criteria:

* Eastern Cooperative Oncology Group performance status of 0 or 1
* Histologically or cytologically confirmed, Stage IV non-squamous NSCLC
* Participants with no prior treatment for Stage IV non-squamous NSCLC
* Previously obtained archival tumor tissue or tissue obtained from fresh biopsy at screening
* Measurable disease, as defined by RECIST v1.1
* Adequate hematologic and end organ function

Exclusion Criteria:

Cancer-Specific Exclusions:

* Active or untreated central nervous system metastases
* Malignancies other than NSCLC within 5 years prior to randomization, with the exception of those with a negligible risk of metastasis or death treated with expected curative outcome

General Medical Exclusions:

* Pregnant or lactating women
* History of autoimmune disease
* History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography scan. History of radiation pneumonitis in the radiation field (fibrosis) is permitted
* Positive test for human immunodeficiency virus
* Active hepatitis B or hepatitis C
* Severe infection within 4 weeks prior to randomization
* Significant cardiovascular disease
* Illness or condition that interferes with the participant's capacity to understand, follow and/or comply with study procedures

Exclusion Criteria Related to Medications:
