A Study of TAR-200 in Combination With Cetrelimab or TAR-200 Alone Versus Intravesical Bacillus Calmette-Guérin (BCG) in Participants With BCG-naïve High-risk Non-muscle Invasive Bladder Cancer

Objective
The purpose of this study is to compare event-free survival (EFS) in participants with Bacillus Calmette-Guerin (BCG)-naive high-risk non-muscle invasive bladder cancer (HR-NMIBC), including high-grade papillary Ta, any T1, or carcinoma in situ (CIS), between TAR-200 plus cetrelimab (Group A) and TAR-200 alone (Group C) versus intravesical BCG (Group B).

Key Eligibility
Inclusion Criteria:
• Histologically confirmed initial diagnosis by local pathology (within 90 days of the initial signed informed consent) of high grade non-muscle invasive bladder cancer (HR-NMIBC) (high-grade Ta, any T1 or carcinoma in-situ [CIS]), in participants who are Bacillus Calmette Guérin (BCG)-naïve. Mixed histology tumors are allowed if urothelial differentiation (transitional cell histology) is predominant. However, the presence of neuroendocrine, micropapillary, signet ring cell, plasmacytoid, or sarcomatoid features will make a participant ineligible
• BCG-naïve (participants who have not received prior intravesical BCG or who previously received but stopped BCG more than 3 years before date of randomization are eligible)
• All visible papillary disease must be fully resected (absent) prior to date of randomization and documented at baseline cystoscopy
• Eastern Cooperative Oncology Group (ECOG) performance status Grade 0, 1, or 2
• All adverse events associated with any prior surgery and/or intravesical therapy must have resolved to common terminology criteria for adverse events (CTCAE) version 5.0 Grade less than (<) 2 prior to date of randomization
• Participants must be willing to undergo all study procedures
Exclusion Criteria:
• Presence or history of histologically confirmed, muscle invasive, locally advanced, nonresectable, or metastatic urothelial carcinoma (that is, greater than and equal to [>=] T2)
• Must not have had urothelial carcinoma or histological variant at any site outside of the urinary bladder (that is, urethra, ureter, or renal pelvis). Ta/any T1/CIS of the upper urinary tract (including renal pelvis and ureter) is allowable if treated with complete nephroureterectomy more than 24 months prior to randomization
• Presence of any bladder or urethral anatomic feature (example, urethral stricture) that, in the opinion of the investigator, may prevent the safe insertion, indwelling use, removal of TAR-200 or administration of intravesical BCG. Participants with tumors involving the prostatic urethra in men will be excluded
• A history of clinically significant polyuria with recorded 24-hour urine volumes greater than 4000 milliliters (mL)
• Indwelling catheters are not permitted; however, intermittent catheterization is acceptable
