Inclusion criteria
Inclusion criteria: - Histologically confirmed initial diagnosis by local pathology (within 90 days of the most recent 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 Guerin (BCG)-naive. - 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 Guerin (BCG)-naive. 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 - All visible papillary disease must be fully resected (absent) prior to date of randomization and documented at baseline cystoscopy.Local urine cytology at screening must be negative or atypical (for high-grade urothelial carcinoma [HGUC]) for patients with papillary only disease (without CIS) - 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
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
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| -Event-free Survival (EFS):Up to 5 years 2 months:EFS is defined as the time from randomization to either the time of the first recurrence of high-risk disease, progression, or death due to any cause, whichever occurs first. For participants with carcinoma In-situ (CIS), persistent disease at 6 months (Week 24) is also considered an EFS event. Progression is defined as: an increase of stage from Ta to T1 or from CIS to T1 or progression to muscle invasive bladder cancer (MIBC) (T greater than or equal to [>=] 2) or to lymph node (N+) or to distant disease (M+), whichever occurs first. | — |
Secondary
| Measure | Time frame |
|---|---|
| -Overall Complete Response (CR) Rate:Up to 5 years 2 months:Overall CR will be measured by determining the percentage of participants with CIS who have no presence of high-risk disease at 6 months. -Duration of CR:Up to 5 years 2 months:Duration of CR is defined from the time of first CR achieved to first evidence of recurrence, progression or death due to any cause (whichever occurs first) for participants who achieve a CR. -Recurrence-Free Survival (RFS):Up to 5 years 2 months:RFS is defined as the time from randomization to the time of the first recurrence of high-risk disease, or death due to any cause, whichever occurs first. -Time to Progression (TTP):Up to 5 years 2 months:TTP is defined as the time from randomization to the date of first documented evidence of disease progression or death due to disease progression, whichever occurs first. -Overall Survival (OS):Up to 5 years 2 months:OS is defined as the time from randomization to death, due to any cause. -Cancer Specific Survival (CSS):Up to 5 years 2 months:CSS is defined as the time from randomization to the date of death due to bladder cancer. -Number of Participants with Adverse Events (AEs) by Grades According to Common Terminology Criteria for Adverse Events (CTCAE):Up to 5 years 2 months:Number of participants with AEs by severity grade as assessed by CTCAE version 5 will be reported. Grade refers to the severity of AE as follows: Grade 1- Mild; Grade 2- Moderate; Grade 3- Severe; Grade 4- Life-threatening; Grade 5- Death related to adverse event. -Number of Participants with Adverse Events (AEs):Up to 5 years 2 months:Number of participants with AEs will be reported. An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintendedsign (including an abnormal finding), symptom, or | — |
