  • Pregnancy or breastfeeding
  • Positive test for human immunodeficiency virus (HIV), with the following exception: Participants with a positive HIV test at screening are eligible provided they are stable on antiretroviral therapy, have a cluster of differentiation 4 (CD4) count ≥ 200 per microliter (/µL), and have an undetectable viral load
  • Participants with active hepatitis B virus (HBV) or hepatitis C virus (HCV). Participants with past HBV infection or resolved HBV infection are eligible. A negative HBV deoxyribonucleic acid (DNA) test must be obtained in these participants prior to enrollment. Participants positive for HCV antibody are eligible only if polymerase chain reaction (PCR) is negative for HCV RNA
  • Active tuberculosis (TB) confirmed by a test performed within 3 months prior to treatment initiation
  • History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins
  • Known hypersensitivity to biopharmaceuticals produced in Chinese hamster ovary cells or any component of the atezolizumab formulation

Participants with controlled type I diabetes mellitus (T1DM) on a stable dose of insulin regimen may be eligible for this study
  • History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest CT scan. History of radiation pneumonitis in the radiation field (fibrosis) is permitted
  • Significant cardiovascular disease, such as New York Heart Association cardiac disease (Class II or greater), myocardial infarction (MI) within the previous 3 months, unstable arrhythmias, or unstable angina

Cancer-Specific Exclusion Criteria for the Surveillance Phase:

  • Any approved anti-cancer therapy, including chemotherapy, or hormonal therapy within 3 weeks prior to study enrollment
  • Adjuvant chemotherapy or radiation therapy for UC following cystectomy
  • Treatment with any other investigational agent or participation in another clinical trial with therapeutic intent within 28 days or 5 half-lives of the drug, whichever is longer, prior to enrollment
  • Malignancies other than UC within 5 years prior to study enrollment

Additional Exclusion Criteria for the Treatment Phase:

  • Any approved anti-cancer therapy, including chemotherapy, or hormonal therapy within 3 weeks prior to randomization to the treatment phase. Hormone-replacement therapy or oral contraceptives are allowed
  • Adjuvant chemotherapy or radiation therapy for UC following cystectomy
  • Treatment with any other investigational agent or participation in another clinical trial with therapeutic intent within 28 days or 5 half-lives of the drug, whichever is longer, prior to randomization to the treatment phase
  • Positive test for HIV, with the following exception: Participants with a positive HIV test at screening are eligible provided they are stable on antiretroviral therapy, have a CD4 count ≥200/μL, and have an undetectable viral load
  • Participants with active HBV or HCV
  • Active tuberculosis confirmed by a test performed within 3 months prior to treatment initiation

INV-assessed DFS was defined as the time from randomization to the first occurrence of a DFS event, defined as any of the following: local (pelvic) recurrence of urothelial carcinoma (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. Participants without an INV-assessed DFS event were censored at the last date the participant was assessed to be alive and recurrence-free as determined with radiographic evidence. Kaplan-Meier (KM) methodology was used to estimate the median DFS.

Overall Survival (OS)
기간: From randomization to death from any cause (Up to 48.2 months)

OS was defined as the time from randomization to death from any cause. Data for participants who did not die at the time of analysis were censored at the date last known to be alive. Data for participants who did not have post-baseline information were censored at the date of randomization. KM methodology was used to estimate the median OS.

Independent Review Facility (IRF)-Assessed DFS
기간: From randomization to the first occurrence of a DFS event (Up to 48.2 months)

IRF-assessed DFS was defined as the time from randomization to the first occurrence of a DFS event, defined as any of the following: 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. Participants without an IRF-assessed DFS event were censored at the last date the participant was assessed to be alive and recurrence-free as determined with radiographic evidence. KM methodology was used to estimate the median DFS.

INV-assessed Disease-specific Survival (DSS)
기간: From randomization to death from UC (Up to 48.2 months)

INV-assessed DSS was defined as the time from randomization to death from UC per investigator assessment of cause of death. Data for participants who did not die will be censored at the last date they were known to be alive. Data for participants who died from causes other than bladder cancer were censored at the date of death. KM methodology was used to estimate the median DSS.

From randomization to death from UC (Up to 48.2 months)
INV-assessed Distant Metastasis-free Survival (DMFS)
기간: From randomization to the first occurrence of a DMFS event (Up to 48.2 months)

INV-assessed DMFS was defined as the time from randomization to the first occurrence of a DMFS event, defined as diagnosis of distant (i.e., non-locoregional) metastasis or death from any cause. Data for participants without a DMFS event were censored at the last date the participant was assessed to be alive and free of distant metastasis. Data for participants with no post-baseline disease assessment were censored at the randomization date. KM methodology was used to estimate the median DMFS.

Time to Confirmed Deterioration (TTCD) in Physical Functioning, Role Functioning & Global Health Status/Quality of Life (GHS/QoL), Assessed by European Organisation for Research & Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30)
기간: Up to 11.8 months

TTCD of physical functioning (PF), role functioning (RF) & health-related quality of life (HRQoL) was defined as time from randomization to first documented confirmed deterioration. Confirmed deterioration=participant's first ≥10-point score decrease from baseline on EORTC QLQ C30 PF, RF or GHS/QoL scale that must be held for ≤2 consecutive time points or followed by death due to cancer progression within 8 weeks from last patient-reported outcomes (PRO) assessment. EORTC QLQ-C30 has 30 questions assessing 5 aspects of participant functioning (physical, emotional, role, cognitive & social), 3 symptom scales (fatigue, nausea & vomiting & pain), GHS/QoL & 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea & financial difficulties). Functioning items are scored on a 4-point scale (1=Not at All to 4=Very Much) & GHS/QoL on a 7-point scale (1=very poor to 7=excellent). Scores are linearly transformed on a scale of 0 to 100. High score=better functioning/better QoL.

Percentage of Participants With ctDNA Clearance
기간: Baseline, Day 1 of Cycles 3 or 5 (Cycle length = 28 days)

ctDNA clearance was defined as the percentage of participants who were ctDNA positive at baseline and ctDNA negative at Cycle 3, Day 1 or Cycle 5, Day 1. Percentages have been rounded off.

Baseline, Day 1 of Cycles 3 or 5 (Cycle length = 28 days)
Number of Participants With Adverse Events (AEs)
기간: From initiation of study treatment up to approximately 5 years

AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

Maximum Serum Concentration (Cmax) of Atezolizumab
기간: 30 minutes post dose on Cycle 1 Day 1 (Cycle length = 28 days)
30 minutes post dose on Cycle 1 Day 1 (Cycle length = 28 days)
Minimum Serum Concentration (Cmin) of Atezolizumab
기간: Pre-dose on Day 1 of Cycles 2, 3, 4, 8 and 12 (Cycle length = 28 days)
Pre-dose on Day 1 of Cycles 2, 3, 4, 8 and 12 (Cycle length = 28 days)
Number of Participants With Anti-drug Antibodies (ADAs) to Atezolizumab
기간: Up to 12.8 months

Participants who received atezolizumab were considered to be treatment-emergent ADA-positive if they were ADA-negative or had missing data at baseline but developed an ADA response following atezolizumab exposure (treatment-induced ADA response), or if they were ADA-positive at baseline and the titer of one or more post-baseline samples was at least 0.60 titer units (t.u.) greater than the titer of the baseline sample (treatment-enhanced ADA response). Participants with a positive post-baseline sample have been reported here.
