Kaplan-Meier methodology was used to estimate DOR.

Minimum Serum Concentration (Cmin) of AtezolizumabPre-infusion (0 hour) on Day 1 of Cycles 2 and 4; Day 22 of Cycles 1, 2, and 4 (1 cycle=6 weeks) (infusion length=30-60 minutes)
M.D. Anderson Symptom Inventory (MDASI) Interference ScoreDays 1 and 22 of Cycles 1 to 24; Day 1 of Cycle 25; treatment discontinuation (up to approximately 2.75 years) (1 cycle=6 weeks)

MDASI questionnaire comprises of 2 parts: symptoms (16 items), interference with daily life (6 items). Participants were asked to rate how much their symptoms interfered with general activity, mood, work, relations with other people, walking, and enjoyment of life during the last 24 hours. Each item in the interference score was answered on a scale of 0 (did not interfere) to 10 (interfered completely). The mean score of all 6 items was reported on the scale of 0 (did not interfere) to 10 (interfered completely).

Percentage of Participants Who Died in IC1/2/3 PopulationRandomization until death due to any cause (until data cut-off date 17 October 2016, up to approximately 2.75 years)
PFS Per RECIST v.1.1 Via Investigator Assessment in Crossover PopulationFrom start of crossover treatment until disease progression or death due to any cause (until data cut-off date 17 October 2016, up to approximately 2.75 years)

PFS was defined as the time from randomization to the first occurrence of PD or death due to any cause. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study, including baseline, and an absolute increase of at least 5 mm; appearance of one or more new target or non-target lesions; or unequivocal progression of existing non-target lesions. Kaplan-Meier methodology was used to estimate PFS.

Percentage of Participants With Anti-Therapeutic Antibodies (ATA) to AtezolizumabCycle 1 Day 1 until treatment discontinuation (until data cut-off date 17 October 2016, up to approximately 2.75 years) (1 cycle=6 weeks)

This outcome measure was planned to be analyzed in 'Atezolizumab' and 'Atezolizumab and Bevacizumab' arms only.

Brief Fatigue Inventory (BFI) Fatigue Level ScoreDays 1 and 22 of Cycles 1 to 24; Day 1 of Cycle 25; treatment discontinuation (up to approximately 2.75 years) (1 cycle=6 weeks)

BFI questionnaire comprises of 2 parts: fatigue level (3 items), interference with daily life (1 item with 6 sub-items). Each items in the fatigue level score was answered on a scale of 0 (no fatigue) to 10 (as bad as you can imagine). The mean score of all 3 items was reported on the scale of 0 (no fatigue) to 10 (as bad as you can imagine).
