Current Primary Outcome:

Current Secondary Outcome:

  • Duration of response (DOR) Assessed by Investigator Using RECIST v1.1 [ Time Frame: From first documented objective response (CR or PR) to disease progression, death, or loss of follow-up, whichever occurs first (assessed at baseline, every 9 weeks for 54 weeks and every 12 weeks thereafter up to 44 months) ]
  • Percentage of Participants Who Were Alive at Year 1 [ Time Frame: Year 1 ]
  • Percentage of Participants Who Were Alive and Progression Free at Year 1 Using RECIST v1.1 [ Time Frame: Year 1 ]
  • Median Time to Deterioration in Global Health Status as Measured by the European Organisation for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire Core 30 (QLQ-C30) Score [ Time Frame: Cycle 1 Day 1 (cycle length = 21 days), on Day 1 of each subsequent cycle up treatment discontinuation visit (up to 44 months) ]
  • Median Time to Deterioration in Physical Function as Measured by the EORTC QLQ-C30 Score [ Time Frame: Cycle 1 Day 1 (cycle length = 21 days), on Day 1 of each subsequent cycle up treatment discontinuation visit (up to 44 months) ]
  • Maximum Atezolizumab Serum Concentration [ Time Frame: Pre-dose,30 min post-end of infusion(infusion length=60min) on Cycle 1 Day 1(1 cycle=21days), pre-dose on Day 1 of Cycles 2,3,4,8 and every 8th cycle thereafter(up to 44months),120 days after last dose or treatment discontinuation visit(up to 44 months) ]
  • Minimum Atezolizumab Serum Concentration [ Time Frame: Pre-dose on Day 1 (1 cycle = 21 days) of Cycles 1,2,3,4,8 and every 8th cycle thereafter (up to 44 months) ]
  • Percentage of Participants With Anti-Therapeutic (Anti-Atezolizumab) Antibodies (ATAs) [ Time Frame: Baseline up to 44 months ]
  • Progression-Free Survival (PFS) Assessed by Investigator Using RECIST v1.1 in Participants Treated with Atezolizumab Montotherapy Compared With Placebo Arm [ Time Frame: Baseline up to disease progression, death, or loss of follow-up, whichever occurs first (assessed at baseline, every 9 weeks for 54 weeks and every 12 weeks thereafter up to 44 months) ]


Original Secondary Outcome:

  • Percentage of Participants with Objective Response, assessed using RECIST v1.1 [ Time Frame: Baseline up to Disease progression or death, whichever occurred first (up to 33 months) ]
  • Duration of response (DOR) Assessed Using RECIST v1.1 [ Time Frame: Baseline up to Disease progression or death, whichever occurred first (up to 33 months) ]
  • PFS Assessed by Independent Review Facility (IRF) Using RECIST v1.1 [ Time Frame: Baseline up to Disease progression or death, whichever occurred first (up to 33 months) ]

  • Percentage of Participants Who Were Alive and Progression Free at Year 1 [ Time Frame: Year 1 ]
  • Median Time to Deterioration in Global Health Status as Measured by the European Organisation for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire Core 30 (QLQ-C30) Score [ Time Frame: Cycle 1 Day 1 (cycle length = 21 days), on Day 1 of each subsequent cycle up treatment discontinuation visit (up to 33 months) ]
  • Median Time to Deterioration in Physical Function as Measured by the EORTC QLQ-C30 Score [ Time Frame: Cycle 1 Day 1 (cycle length = 21 days), on Day 1 of each subsequent cycle up treatment discontinuation visit (up to 33 months) ]
