Time frame
Pre-dose (0 hours) on Day 1 of Cycles 1, 2, 3, 4, 8, 12, 16, and at every 8 cycles thereafter until TD, at TD, and at 90-150 days after TD (maximum up to 45 months) (1 Cycle = 28 days)

Analysis population: Anti-Drug Antibody (ADA) population: * Baseline ADA-evaluable population: all participants with at least one evaluable ADA assay result from a baseline sample * Post baseline ADA-Evaluable population: all participants with at least one evaluable ADA assay result from at least one post-baseline 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

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.
