Other Name: Tecentriq
Active Comparator: Arm B: Chemotherapy (Vinflunine, Paclitaxel, or Docetaxel)
Participants randomized to the chemotherapy arm will receive vinflunine, paclitaxel, or docetaxel per the investigator's choice. Vinflunine 320 milligrams per square meter (mg/m^2), paclitaxel 175 mg/m^2, or docetaxel 75 mg/m^2 will be administered intravenously on Day 1 of each 21-day cycle until disease progression per standard RECIST v1.1 or unacceptable toxicity.
 Drug: Docetaxel
Docetaxel 75 mg/m^2 will be administered intravenously on Day 1 of each 21-day cycle.

Drug: Paclitaxel
Paclitaxel 175 mg/m^2 will be administered intravenously on Day 1 of each 21-day cycle.

Vinflunine 320 mg/m^2 will be administered intravenously on Day 1 of each 21-day cycle.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: Between randomization and death due to any cause, up to approximately 25 months after first participant enrolled ]
    OS was defined as time from randomization to death from any cause.


Secondary Outcome Measures :
  1. Progression-free Survival (PFS) as Determined by the Investigator With Use of RECIST v1.1 [ Time Frame: Up to approximately 25 months after first participant enrolled ]
    PFS was defined as the time between the date of randomization and the date of first documented progression of disease (PD) or death, whichever occurred first. PD was determined on the basis of investigator assessment with use of RECIST v1.1. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum of diameters on study (including baseline). In addition to the relative increase of 20%, the sum of diameters had to demonstrate an absolute increase of >/= 5 millimeters (mm).

  2. Unconfirmed Duration of Response (DOR) as Determined by the Investigator With Use of RECIST v1.1 [ Time Frame: Up to approximately 25 months after first participant enrolled ]
    DOR was defined as the time from first occurrence of a CR or PR, whichever came first, to first documented PD or death, whichever occurred first. Disease progression was determined on the basis of investigator assessment with use of RECIST v1.1. CR: disappearance of all target lesions. PR: At least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum of diameters on study (including baseline). In addition to the relative increase of 20%, the sum of diameters must also demonstrate an absolute increase of >/= 5 mm.

  3. Percentage of Participants With Adverse Events (AEs) [ Time Frame: Up to approximately 46 months after first participant enrolled ]
    An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

  4. Percentage of Participants With Post-Baseline Anti-therapeutic Antibodies (ATA) to Atezolizumab [ Time Frame: Predose (0 hours) on Day 1 of Cycles 1, 2, 3, 4 and every 8 cycles thereafter; at treatment discontinuation (up to 25 months); at 120 days after last dose of atezolizumab (up to 25 months; each cycle is 21 days) ]
    Participants were considered post-baseline ATA positive if they had post-baseline ATAs to Atezolizumab that were treatment-induced or treatment-enhanced. Participants had treatment-induced ATAs if they had a baseline-negative ATA result and developed ATAs at any time after initial drug administration. Participants had treatment-enhanced ATAs if they had a baseline-positive ATA result that showed an enhanced signal that was >/= 0.60 titer units at any time after initial drug initiation.

  5. Minimum Observed Serum Atezolizumab Concentration (Cmin) [ Time Frame: Predose (0 hours) on Day 1 of Cycles 1, 2, 3, 4 and every 8 cycles thereafter; at treatment discontinuation (up to 25 months); at 120 days after last dose of atezolizumab (up to 25 months; each cycle is 21 days) ]
    Cmin was measured for all participants that received at least one dose of Atezolizumab.

  6. Percentage of Participants With Unconfirmed Objective Response Rate (ORR) as Determined by the Investigator With Use of Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST v1.1) [ Time Frame: Up to approximately 25 months after first participant enrolled ]
    ORR was defined as the percentage of participants, who had an objective response. Objective response was defined as either a complete response (CR) or partial response (PR) as determined by the investigator with use of Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1). Objective response in this study did not need to be a confirmed response. CR: disappearance of all target lesions. PR: At least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR. ORR=CR+PR

  7. Maximum Observed Serum Atezolizumab Concentration (Cmax) [ Time Frame: 30 minutes post dose on Day 1 of Cycles 1 ]
    Cmax was measured for all participants that received at least one dose of Atezolizumab.

  8. Change From Baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire Core 30 (QLQ-C30) Score: Global Health Status Scale [ Time Frame: Cycle 1 Day 1 (prior to any health care interaction), on Day 1 of each subsequent cycle, and at 30 days after the last treatment dose (Up to approximately 25 months; each cycle is 21 days) ]
    The EORTC QLQ-C30 includes five functional scales (physical, role, cognitive, emotional, social); a global health status (GHS)/quality of life (QoL) scale; and items measuring fatigue, pain, nausea and vomiting, dyspnea, appetite loss, sleep disturbance, constipation, diarrhea, and financial difficulties. The score range for each scale and single-item measure is 0 to 100, where higher scores indicate a higher response level (i.e., better functioning, better QoL, worse symptoms). Key scales included physical functioning, and fatigue, and GHS.

  9. Change From Baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire Core 30 (QLQ-C30) Score: Physical Functioning Scale [ Time Frame: Cycle 1 Day 1 (prior to any health care interaction), on Day 1 of each subsequent cycle, and at 30 days after the last treatment dose (Up to approximately 25 months; each cycle is 21 days) ]
    The EORTC QLQ-C30 includes five functional scales (physical, role, cognitive, emotional, social); a global health status (GHS)/quality of life (QoL) scale; and items measuring fatigue, pain, nausea and vomiting, dyspnea, appetite loss, sleep disturbance, constipation, diarrhea, and financial difficulties. The score range for each scale and single-item measure is 0 to 100, where higher scores indicate a higher response level (i.e., better functioning, better QoL, worse symptoms). Key scales included physical functioning, and fatigue, and GHS.

  10. Change From Baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire Core 30 (QLQ-C30) Score: Fatigue Symptom Scale [ Time Frame: Cycle 1 Day 1 (prior to any health care interaction), on Day 1 of each subsequent cycle, and at 30 days after the last treatment dose (Up to approximately 25 months; each cycle is 21 days) ]
    The EORTC QLQ-C30 includes five functional scales (physical, role, cognitive, emotional, social); a global health status (GHS)/quality of life (QoL) scale; and items measuring fatigue, pain, nausea and vomiting, dyspnea, appetite loss, sleep disturbance, constipation, diarrhea, and financial difficulties. The score range for each scale and single-item measure is 0 to 100, where higher scores indicate a higher response level (i.e., better functioning, better QoL, worse symptoms). Key scales included physical functioning, and fatigue, and GHS.
