Details and patient eligibility

About

The purpose of study is to compare bladder intact-event free survival (BI-EFS) in participants receiving TAR-200 in combination with intravenous (IV) cetrelimab versus concurrent chemoradiotherapy.

Enrollment: 550 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• 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 Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 Grade less than (<) 2 prior to randomization
• 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: Bone marrow function (without the support of cytokines or erythropoiesis-stimulating agent in preceding two weeks): Absolute neutrophil count (ANC) greater than or equal to (>=) 1,500/cubic millimeters (mm^3); Platelet count >=80,000/mm^3; Hemoglobin >=9.0 grams per deciliter (g/dL); Liver function: (Total bilirubin less than or equal to (<=) 1.5 * upper limit of normal (ULN) or direct bilirubin <= ULN for participants with total bilirubin levels greater than (>)1.5*ULN (except participants with Gilbert's Syndrome, who must have a total bilirubin < 3.0 mg/dL), and Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) less than or equal to (<=) 2.5* institutional ULN); Renal function: Creatinine clearance >=30 mL/min using the Cockcroft-Gault 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

Exclusion criteria

• Must not have had urothelial carcinoma or histological variant at any site outside of the urinary bladder. Ta/T1/Carcinoma in situ (CIS) of the upper urinary tract (including renal pelvis and ureter) is allowable if treated with complete nephroureterectomy more than 24 months prior to initiating study
• Must not have diffuse CIS based on cystoscopy and biopsy. Diffuse, or multi-focal, CIS is defined as the presence of at least 4 distinct CIS lesions in the bladder at the time of the Screening re-TURBT
• Participants must not have evidence of cT4b, or N1-3, or M1 disease based on local radiology staging (chest, abdomen, and pelvis must be performed using Computed tomography [CT] or Magnetic resonance imaging [MRI]) within 42 days prior to randomization
• 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
• Evidence of bladder perforation during diagnostic cystoscopy. Participant is eligible if perforation has healed prior to randomization

---

550 participants in 2 patient groups

TAR-200 + Cetrelimab

Experimental group

Description:

Participants will receive intravesical TAR-200 every 3 weeks (21 days indwelling) for first 18 weeks and thereafter from Week 24 every 12 weeks through study Year 3 in combination with intravenous (IV) Cetrelimab.

Treatment:

Biological: Cetrelimab

Drug: TAR-200

Chemotherapy (cisplatin or gemcitabine) + Radiation Therapy

Active Comparator group

Description:

Participants will receive chemotherapy based on investigator's choice from either cisplatin intravenously once weekly for 4 to 6 treatment weeks or gemcitabine intravenously twice weekly for 4 to 6 treatment weeks as Standard of Care (SOC) along with radiation therapy from either conventional radiotherapy (64 Gray \[Gy\], bladder only) for up to 6.5 treatment weeks or hypo-fractionated radiotherapy (55 Gy, bladder only) for up to 4 weeks.

Treatment:

Drug: Gemcitabine

Radiation: Conventional radiation therapy

Radiation: Hypo-fractioned radiation therapy

Drug: Cisplatin
