Overview
The purpose of this study is to assess the safety and efficacy of avelumab in combination with other anti-tumor agents as a maintenance treatment in participants with bladder cancer.
Eligibility
Inclusion Criteria:
- Participants with histologically confirmed, unresectable locally advanced or metastatic urothelial carcinoma. Both transitional cell and mixed transitional/nontransitional cell histologies are allowed, but transitional cell carcinoma must be the predominant histology
- Participants has documented Stage IIIA/IIIB with N1-N3, or Stage IV disease (per American Joint Committee on Cancer/International Union for Cancer Control Tumor Node Metastasis system, 8th edition) at the start of first line chemotherapy.
- The last dose of first line chemotherapy must have been received no less than 4 weeks, and no more than 10 weeks, prior to randomization in the present study
- Estimated life expectancy of at least 3 months
- Participants without progressive disease as per RECIST v1.1 guidelines following completion of 4 to 6 cycles of 1L chemotherapy. Eligibility based on this criterion will be determined by Investigator review of pre chemotherapy and post chemotherapy radiological assessments (CT/MRI scans).
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
- Adequate hematological, hepatic, and renal function as defined in the protocol
- Other protocol defined inclusion criteria could apply
Exclusion Criteria:

- Participants with active infection 48 hours before randomization requiring systemic therapy
- Participants with known prior or suspected hypersensitivity to study drugs or any component in their formulations
- Participants with prior adjuvant or neoadjuvant systemic therapy within 12 months of randomization
- Participants with vaccination within 4 weeks of the first dose of study treatment and while on trial is prohibited except for administration of inactivated vaccines (for example, inactivated influenza vaccines) administered >= 2 weeks prior first dose of study treatment. All severe acute respiratory syndrome coronavirus (SARS-CoV-2) vaccines approved or authorized by local Health Authorities are allowed
