1.=18 years (or the legal age of consent where the study takes place)
2.Histologically proven, cT2-T4a N0, M0 infiltrating urothelial carcinoma (AJCC 2017) 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
3.Participants with no residual tumor, or intravesical tumor size of =3 cm following TURBT are eligible; debulking TURBT for any residual disease is encouraged but not mandated. Participants with persistent tumors >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
4.Deemed eligible for and willing to undergo RC by the attending urologist
5.Eastern Cooperative Oncology Group (ECOG) performance status Grade 0 or 1
6.Thyroid function tests within normal range or stable on hormone supplementation per Investigator assessment
7.Adequate bone marrow, liver, and renal function (refer to study protocol for details)
8.Participants must refuse cisplatin-based combination chemotherapy (and understand the risk and benefits of doing so) or be deemed ineligible for cisplatin-based chemotherapy by meeting at least one of the following criteria:
• GFR <60 mL/min/1.73 m2 (assessed using the CKD-EPI equation)
• Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 Grade =2 audiometric hearing loss
• CTCAE version 5.0 Grade =2 peripheral neuropathy
9.Prior systemic chemotherapy for indications other than urothelial cell carcinoma of the bladder is permitted, but interval between this treatment and study enrollment must exceed 24 months. All toxicities attributed to prior anti-cancer therapy other than alopecia and fatigue must have resolved to Grade 1 (NCI-CTCAE version 5.0) or baseline before administration of study treatment. Participants with toxicities attributed to prior anticancer therapy which are not expected to resolve and result in long lasting sequelae, such as peripheral neuropathy after platinum-based therapy or audiometric hearing loss, are ineligible.
10.All adverse events associated with any prior surgery must have resolved to CTCAE version 5.0 Grade <2 prior to randomization
11.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 female participants must agree not to be pregnant, breastfeeding, or planning to become pregnant while enrolled in this study or within 6 months after the last dose of study treatment
a. A female 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)
A female participant must also:
• agrees to not donate eggs (ova, oocytes, or freeze for future use) for the purposes of assisted reproduction during the study and for at least 6 months after the last dose of study
1. Active malignancies other than the disease being treated under study
2. Must not have received prior systemic chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to starting study treatment
3. Must not have had urothelial carcinoma or histological variant at any site outside of the urinary bladder
4. Participants must not have evidence of cT4b, or N1-3, or M1 disease based on central radiology staging within 42 days prior to randomization
5. 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
6. Uncontrolled adrenal insufficiency
7. A history of clinically significant polyuria with recorded 24-hour urine volumes greater than 4,000 mL
8. History of uncontrolled cardiovascular disease
9. Must not have active tuberculosis
10. Criterion - deleted per Amendment 1
11.Pyeloureteral tube externalized to the skin is exclusionary
12.Indwelling catheters are not permitted
13. Participants with an active autoimmune disease that required systemic treatment in the past 2 years
14. Participants must not have clinically significant liver disease that precludes participant treatment regimens prescribed on the study
15.Human immunodeficiency virus infection
16.Evidence of active or chronic hepatitis B or C infection
17.Concurrent urinary tract infection (UTI), that cannot be cleared with antibiotic therapy
18.Criterion deleted per Amendment 2
19.Evidence of interstitial lung disease or active non-infectious pneumonitis.
20.Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, unstable angina pectoris, or psychiatric illness/social situations that would limit compliance with study requirements
21.Participants with current acute diverticulitis, intra-abdominal abscess, gastrointestinal obstruction and abdominal carcinomatosis which are known risk factors for bowel perforation, and participants who have a history immune-mediated colitis
22.Criterion deleted per Amendment 2
23.Not recovered from adverse events due to a previously administered agent
24.Prior systemic chemotherapy for urothelial cell carcinoma of the bladder at any time.
25.Pelvic radiotherapy administered less than 6 months prior to screening.
26.Received a live virus vaccine within 30 days of initiation of study treatment. Inactivated (non-live or non-replicated) vaccines approved or authorized for emergency use (eg, Coronavirus Disease 2019 [COVID-19]) are allowed
27.Criterion deleted per Amendment 2
28.Active infection requiring systemic intravenous therapy within 14 days prior to randomization.
29.Received intervening intravesical chemotherapy or immunotherapy from the time of most recent cystoscopy/TURBT to starting study treatment. Immediate post-TURBT single-dose peri-operative intravesical chemotherapy is allowed per institutional guidelines in the screening phase.
30.Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti cytotoxic T-lymphocyte antigen-4 (CTLA-4) antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways.
31.Participants with a history of Grade =3 toxic effects when using anti-TNF or anti-IL-6 agents are excluded.
32.Participants still recovering from toxicity of prior anticancer therapy which was received more than 24 months prior to enrollment (except toxicities which are not clinically signific
