Who can take part
You may be able to join if
- ≥18 years (or the legal age of consent in the jurisdiction in which the study is taking place) at the time of informed consent.
- Participants must be willing and able to adhere to the lifestyle restrictions specified in this protocol
- Histologically proven, cT2-T4a N0, M0 urothelial carcinoma of the bladder. Initial diagnosis must have been within 120 days of randomization date. Participants with variant histologic subtypes (e.g. squamous cell carcinoma) are allowed if urothelial (transitional cell) differentiation is predominant. However, the presence of small cell or neuroendocrine variants will make a participant ineligible.
- Ineligible for or have elected not to undergo radical cystectomy.
- All adverse events associated with any prior surgery and/or intravesical therapy must have resolved to CTCAE version 5.0 Grade ≤ 2 prior to randomization
- Eastern Cooperative Oncology Group (ECOG) performance status Grade 0, 1, or 2
You likely can't join if
- Active malignancies other than the disease being treated under study.
- Received intervening serial intravesical chemotherapy or immunotherapy from the time of pre-screening (diagnostic) or screening (completion) cystoscopy/Transurethral Resection of Bladder Tumor to starting study treatment. Peri-operative intravesical chemotherapy prior to study treatment is allowed per institutional guidelines
- Prior therapy with an anti-programmed cell death 1, anti-PD-ligand agent, or with an agent directed to another co-inhibitory T-cell receptor.
- Participants with a history of Grade ≥3 toxic effects when using antiTNF or anti-IL-6 agents.
- Received prior systemic chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to starting study treatment or not recovered from adverse events due to a previously administered agent. Participants with a history of prior pelvic radiotherapy are excluded

- Eastern Cooperative Oncology Group (ECOG) performance status Grade 0, 1, or 2
- Thyroid function tests are within the normal range per investigator assessment (or stable on hormone supplementation). Investigators may consult an endocrinologist for participant eligibility assessment in the case of equivocal or marginal test results
- Adequate bone marrow, liver, and renal function: a. Bone marrow function (without the support of cytokines or erythropoiesis-stimulating agent in preceding 2 weeks): i. Absolute neutrophil count (ANC) ≥ 1,500/mm^3 ii. Platelet count ≥80,000/mm^3 iii. Hemoglobin ≥9.0 g/dL b. Liver function: i. Total bilirubin ≤1.5 x ULN OR direct bilirubin ≤ULN for participants with total bilirubin levels >1.5xULN (except participants with Gilbert's Syndrome, who must have a total bilirubin < 3.0 mg/dL), ii. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5x institutional ULN c. Renal function: Creatinine clearance ≥30 mL/min using the CockcroftGault formula. 24-hour creatinine clearance test will also be accepted for estimating renal function in situations where Cockcroft-Gault formula is not a good predictor of estimating adequate renal function. Note: If cisplatin is chosen as the radio-sensitizing agent, creatinine clearance must be ≥50 mL/min
- Contraceptive use by participants should be consistent with local regulations regarding the use of contraceptive methods for participants participating in clinical studies. Investigators will advise participants on the options for banking of sperm and ova, for reproductive conservation. a. A participant must be either of the following: i. Not of childbearing potential ii. Of childbearing potential and practicing true abstinence, or have a sole partner who is vasectomized, or practicing at least 1 highly effective user independent method of contraception. Participant must agree to continue the above throughout the study and for 6 months after the last dose of study treatment. Note: If a participant becomes of childbearing potential after start of the study, the participant must comply with point (ii), as described above. A participant must also agree to not donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for at least 6 months after the last dose of study treatment, and not be breastfeeding and not planning to become pregnant during the study and for at least 6 months after the last dose of study treatment. Participants should consider preservation of eggs prior to study treatment as anti-cancer treatments may impair fertility. Investigators will advise participants on the options for banking of ova for reproductive Conservation b. Participants must wear a condom (with or without spermicidal foam/gel/film/cream/suppository) when engaging in any activity that allows for passage of ejaculate to another person during the study and for a minimum of 6 months after receiving the last dose of study treatment. Partners of participants who can conceive a child, if that partner is of childbearing potential, must also be practicing a highly effective method of contraception. If the participant is vasectomized, they still must wear a condom (with or without spermicidal foam/gel/film/cream/suppository), but their partner is not required to use contraception. A participant must also agree to not donate sperm for the purpose of reproduction during the study and for at least 6 months after the last dose of study treatment, and not plan to conceive a child while enrolled in the study or within 6 months after the last dose of study treatment. Participants should consider preservation of sperm prior to study treatment as anti-cancer treatments may impair fertility. Investigators will advise participants on the options for banking of sperm for reproductive conservation

- Criterion added per Global Amendment 3: The participant is unable to comply with the requirements of this protocol, including any factors that are likely to affect the participant's return for scheduled visits and follow-up.
- Criterion added per Global Amendment 3: Any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (eg, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments.
