Brief Title: TAR-200 in Combination With Cetrelimab, TAR-200 Alone, or Cetrelimab Alone in Participants With Non-Muscle Invasive Bladder Cancer (NMIBC) Unresponsive to Intravesical Bacillus Calmette-Guerin Who Are Ineligible for or Elected Not to Undergo Radical Cystectomy

PRIMARY OUTCOMES

Primary Outcome 1 - Measure: Overall Complete Response (CR) Rate

Primary Outcome 1 - Timeframe: Up to 5 years

CONDITION

• Urinary Bladder Neoplasms

ELIGIBILITY

Inclusion Criteria:
Histologically confirmed diagnosis of persistent or recurrent (carcinoma in situ [CIS] or Tumour in situ [Tis]), with or without papillary disease (T1, high-grade Ta) within 12 months of completion of the last dose of Bacillus Calmette-Guerin (BCG) therapy, in participants who have received adequate BCG. Mixed histology tumors are allowed if urothelial differentiation (transitional cell histology) is predominant (example, less than (<) 20 percent (%) variant histologic subtype). However, the presence of neuroendocrine, micropapillary, signet ring cell, plasmacytoid, or sarcomatoid features will make a participant ineligible. For participants with lamina propria invasion (T1) on the screening biopsy/ transurethral resection of bladder tumor (TURBT), muscularis propria must be present in order to rule out Muscle Invasive Bladder Cancer (MIBC) - All visible papillary disease must be fully resected (absent) prior to randomization (residual CIS acceptable) and documented in the electronic case report form (eCRF) at screening cystoscopy - Participants must be ineligible for or have elected not to undergo radical cystectomy - BCG-unresponsive high-risk NMIBC after treatment with adequate BCG therapy defined as a minimum of 5 of 6 full doses of an induction course (adequate induction) plus 2 of 3 doses of a maintenance course, or at least 2 of 6 doses of a second induction course - Eastern Cooperative Oncology Group (ECOG) performance status Grade 0, 1, or 2
Exclusion Criteria:
Histologically confirmed, muscle-invasive, locally advanced, nonresectable, or metastatic urothelial carcinoma (that is, T2, T3, T4, and/or Stage IV

- Must not have had urothelial carcinoma or histological variant at any site outside of the urinary bladder. Ta/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

- Participants with an active, known or suspected autoimmune disease. Participants with autoimmune disorders not requiring systemic treatment (example, skin conditions such as vitiligo, psoriasis, alopecia) or conditions requiring hormonal replacement therapies such as type 1 diabetes mellitus or hypothyroidism are permitted to enroll

- Active hepatitis B or C infection (for example, participants with history of hepatitis C infection but undetectable hepatitis C virus polymerase chain reaction (PCR) test and participants with history of hepatitis B infection with positive hepatitis B surface antigen (HBsAg) antibody and undetectable PCR are allowed)

- Prior therapy with an anti-programmed-cell death 1 (PD-1), anti-PD-ligand 2 (L2) agent, or with an agent directed to another co-inhibitory T-cell receptor
