Brief Summary:
This Phase III, open-label, randomized, multicenter study is to evaluate the efficacy and safety of adjuvant treatment with atezolizumab compared with observation in participants with muscle-invasive UC who are at high risk for recurrence following resection. Eligible participants were randomized by a 1:1 ratio into atezolizumab group or control group.

Primary Outcome Measures :
  1. Disease-Free Survival (DFS), as Assessed by Investigator [ Time Frame: Randomization up to first occurrence of DFS event (up to approximately 50 months) ]
    DFS is defined as the time from randomization to the time of first occurrence of a DFS event. DFS events include: local (pelvic) recurrence of UC (including soft tissue and regional lymph nodes); urinary tract recurrence of UC (including all pathological stages and grades); distant metastasis of UC; or death from any cause. Tumor assessment will be performed using radiographic evaluations.


Secondary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: Randomization until death due to any cause (up to approximately 50 months) ]
    Overall survival is defined as the time from randomization to the date of death from any cause, regardless of whether the death occurs during study treatment or following treatment discontinuation.

  2. Disease-Specific Survival (DSS), as Assessed by Investigator [ Time Frame: Randomization until death due to UC (up to approximately 50 months) ]
    DSS is defined as the time from randomization until the date of death from UC.

  3. Distant Metastasis-Free Survival (DMFS) [ Time Frame: Randomization up to diagnosis of distant metastases or death from any cause (up to approximately 50 months) ]
    DMFS is defined as the time from randomization to the date of diagnosis of distant (that is, non-locoregional) metastases or death from any cause. Tumor assessment will be performed using radiographic evaluations.

  4. Non-Urinary Tract Recurrence-Free Survival (NURFS) [ Time Frame: Randomization up to time of first occurrence of a NURFS event (up to approximately 50 months) ]
    NURFS is defined as the time from randomization to the time of first occurrence of a NURFS event. NURFS events include: local (pelvic) recurrence of UC (including soft tissue and regional lymph nodes); distant metastasis of UC; or death from any cause. Tumor assessment will be performed using radiographic evaluations.

  5. Percentage of Participants With Adverse Events (AEs) [ Time Frame: Screening up to approximately 50 months ]
    Percentage of participants with at least one Adverse Event.

  6. Percentage of Participants With Anti-Therapeutic Antibodies (ATAs) to Atezolizumab [ Time Frame: Baseline up to approximately 50 months ]
    Percentage of participants with anti-therapeutic antibodies to atezolizumab.

  7. EuroQol 5-Dimension 5-Level (EQ-5D-5L) Visual Analogue Scale Score [ Time Frame: Day 1 of Cycle 1 up to approximately 50 months (Cycle length = 21 days) ]
    The EQ-5D-5L is a generic preference-based HRQoL questionnaire that provides a single index value for health status and is used to inform pharmacoeconomic evaluations and to measure general health status. Visual analog scale (VAS) allows the patient to indicate, on a scale of 0-100, how his or her health is on the day of assessment, with 100 being the "best imaginable health state" and 0 being the "worst imaginable health state."

  8. Minimum Observed Serum Atezolizumab Concentration (Cmin) [ Time Frame: Pre-dose (Hour 0) on Day 1 of Cycles 1, 2, 3, 4, every 8 cycles from Cycle 8, at treatment discontinuation, 120 days after treatment discontinuation (up to approximately 50 months))(Cycle length = 21 days) ]
    Minimum observed serum atezolizumab concentration (Cmin) prior to infusion on Day 1 of Cycles 1, 2, 3, and 4; every 8 cycles starting on Cycle 8; at treatment discontinuation; and at 120 days after the last dose of atezolizumab.

  9. Maximum Observed Serum Atezolizumab Concentration (Cmax) [ Time Frame: Day 1 of Cycle 1 (Cycle length = 21 days) ]
    Maximum observed serum atezolizumab concentration (Cmax) after infusion on Day 1 of Cycle 1.
