What was measured

Deterioration in Global Health Status/HRQoL is defined as a decrease of at least 10 points on the Global Health Status /HRQoL scale (comprised of 2 items: 29 and 30) of the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). The 2 items use 7-point scale (1 = very poor to 7 = Excellent). Scores are averaged, transformed to 0-100 scale; where higher score=better level of functioning or greater degree of symptoms.

Analysis population: PRO-evaluable populations: participants in the ITT population with baseline PRO assessment and at least one post-baseline PRO assessment in the questionnaire of interest (European Organization for the Research and Treatment of Cancer \[EORTC\] Quality-of-life Questionnaire \[QLQ\] C30, EORTC QLQ BR-23 or FACT-G)

Groups in this outcome

Placebo and Paclitaxel

Participants will receive placebo matching to atezolizumab via IV infusion on Days 1 and 15 (± 3 days) of every 28-day cycle along with paclitaxel administered at a dose of 90 mg/m\^2 via IV infusion on Days 1, 8, and 15 of every 28-day cycle until disease progression or unacceptable toxicity.

Atezolizumab and Paclitaxel

Participants will receive atezolizumab at a dose of 840 milligrams (mg) via intravenous (IV) infusion on Days 1 and 15 (± 3 days) of every 28-day cycle along with paclitaxel administered at a dose of 90 mg per square meter (mg/m\^2) via IV infusion on Days 1, 8, and 15 of every 28-day cycle until disease progression or unacceptable toxicity.
