Korábbi kezelés

• Must not have received prior systemic chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to starting study treatment
• Participants must not have evidence of cT4b, or N1-3, or M1 disease based on central radiology staging (chest, abdomen, and pelvis must be performed using computed tomography [CT] or magnetic resonance imaging [MRI]) within 42 days prior to randomization
• Prior systemic chemotherapy for urothelial cell carcinoma of the bladder at any time
• Currently participating or has participated in a study of an investigational agent and received study therapy or investigational device within 4 weeks prior to enrollment
• Participants with evidence of bladder perforation during diagnostic cystoscopy. Participant is eligible if perforation has resolved prior to dosing

Egyéb

• Presence of any bladder or urethral anatomic feature that, in the opinion of the Investigator, may prevent the safe placement, indwelling use, or removal of TAR-200

• Histologically proven, cT2-T4a N0, M0 infiltrating urothelial carcinoma of the bladder. Initial diagnosis must have been within 120 days of randomization date. Participants with variant histologic subtypes are allowed if tumor(s) demonstrate urothelial predominance. However, the presence of small cell or neuroendocrine variants will make a participant ineligible
• Participants with no residual tumor, or intravesical tumor size of less than or equal to (<=)3 centimeter (cm) following transurethral resection of bladder tumor (TURBT) are eligible; debulking TURBT for any residual disease is encouraged but not mandated. Participants with persistent tumors greater than (>)3 cm at screening must undergo a second debulking, re-staging TURBT. Participants will be ineligible if any individual tumor is >3 cm after debulking TURBT
• Deemed eligible for and willing to undergo RC by the operating urologist
• Eastern Cooperative Oncology Group (ECOG) performance status Grade 0 or 1
• Thyroid function tests within normal range or stable on hormone supplementation per investigator assessment. Investigators may consult an endocrinologist for participant eligibility assessment in the case of equivocal or marginal tests results
• All adverse events associated with any prior surgery must have resolved to common terminology criteria for adverse events (CTCAE) version 5.0 Grade less than (<) 2 prior to randomization
