About this trial
The main purpose of this study is to compare the disease-free survival between participants receiving treatment with TAR-210 versus investigator's choice of intravesical chemotherapy for treatment of intermediate-risk NMIBC.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Main study only: Have a histologically confirmed diagnosis (within 90 days of randomization) of IR-NMIBC with at least one of the following criteria fulfilled: a. Ta low grade (LG)/ Grade 1 (G1): primary or recurrent, b. Ta LG/G2: primary or recurrent and c. Greater than or equal to (>=) 1 of the following risk factors: i. Multiple Ta LG tumors, ii. Solitary LG tumor >= 3 cm, iii. Early recurrence (less than [<] 1 year), iv. Frequent recurrence (greater than [>] 1 per year), v. Recurrence after prior adjuvant intravesical treatment (single perioperative dose of chemotherapy does not fulfill this risk factor)
Substudy only: Have a histologically confirmed new diagnosis (within 90 days of randomization) of IR-NMIBC for whom MMC is deemed the therapy of choice according to local standard of care with at least 1 of the following criteria fulfilled: a. Ta LG/G1, b. Ta LG/G2, and >=1 of the following risk factors: i) Multiple Ta LG tumors, ii) Solitary LG tumor >=3 cm
Have a susceptible fibroblast growth factor receptor (FGFR) mutation or fusion either by urine testing or tumor tissue testing (from TURBT tissue), as determined by central or local testing
Participants must be willing to undergo all study procedures (e.g., multiple cystoscopies from Screening through the end of study and TURBT for assessment of recurrence/progression) and receive the assigned treatment, including intravesical chemotherapy if randomized into that arm.
Disqualifiers
Known allergies, hypersensitivity, or intolerance to any study component or its excipients, including: a. Erdafitinib excipients; b.TAR-210 drug delivery system constituent materials ; c. urinary placement catheter materials; d. MMC or chemically related drugs; e. Gemcitabine or chemically related drugs
Presence of any bladder or urethral anatomic feature (that is, urethral stricture) that, in the opinion of the investigator, may prevent the safe insertion, indwelling use, removal of TAR-210 or passage of a urethral catheter for intravesical chemotherapy
Polyuria with recorded 24-hour urine volumes > 4000 milliliters (mL)
Current indwelling urinary catheters, however, intermittent catheterization is acceptable

Treatment groups
Trial outcomes
Primary outcomes
Disease Free Survival (DFS)
DFS is measured as the time from randomization to the date of the first documented recurrence of Ta non-muscle invasive bladder cancer (NMIBC) of any grade, disease progression, or death due to any cause, whichever occurs first.
Secondary outcomes
Time to next Treatment (TTNT)
TTNT is measured as the time from randomization to the date of first documented subsequent treatment (local, systemic, surgical, or interventional) for bladder cancer.
High Grade Recurrence-free Survival (HG RFS)
HG RFS is measured as the time from randomization to the date of first documented evidence of HG NMIBC or death, whichever occurs first
Progression Free Survival (PFS)
PFS is measured as the time from randomization to the date of first documented evidence of disease progression or death, whichever occurs first.
Number of Diagnostic and Therapeutic Invasive Urological Interventions after Study Treatment
Number of diagnostic and therapeutic invasive urological interventions after study treatment, that is, endoscopic procedures (e.g., cystoscopies, transurethral resection of bladder tumors (TURBTs), ureteroscopies, urethral interventions, urethral stricture/bladder neck incision), catheterization (intravesical, suprapubic), intravesical treatments, major surgeries (e.g., radical cystectomy, simple cystectomy, urethroplasty) will be reported.
