Time frame
Pre-dose (0 hours) on Day 1 of Cycle 3 (1 Cycle = 28 days)

Analysis population: PK-evaluable population: first 60 participants who received any dose of Paclitaxel and who have at least one evaluable post-baseline PK sample. For all safety, PK and immunogenicity analyses, participants were grouped according to the treatment actually received, including cases in which atezolizumab was received in error.

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.
