Study Arms:
- Cohort 1: Treatment-naive Cisplatin Ineligible Participants (Type: EXPERIMENTAL): Participants with advanced disease who are treatment-naive for advanced urothelial carcinoma and cisplatin ineligible will receive atezolizumab 1200 mg via IV infusion on Day 1 of 21-day cycles until disease progression per RECIST v1.1 criteria or unmanageable toxicity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
