PD is defined as \>/=20% relative increase and \>/=5 mm of absolute increase in the SD of TLs, taking as reference the smallest SD recorded since treatment started, or appearance of 1 or more new lesions.

Analysis population: ITT population: all randomized participants, whether or not the assigned study treatment was received

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.
