Eligible patients will be randomized in a 1:1 ratio to UGN-102 ± TURBT or TURBT alone. Randomization will be stratified by the presence of a previous LG NMIBC episode within 1 year of the current diagnosis (yes or no). Starting at Day 1, patients randomized to the UGN-102 ± TURBT group will receive 6 once-weekly intravesical instillations of UGN-102 and patients randomized to the TURBT alone group will undergo TURBT.~Patients in both treatment groups will return to the clinic at approximately 3 months after the initiation of treatment (7 weeks ± 1 week after the last weekly instillation for the UGN-102 ± TURBT group and 12 weeks ± 1 week after TURBT for the TURBT alone group) to determine response to treatment. Patients determined to have a complete response (CR) will receive no further treatment and will enter the follow-up period of the study. Patients determined to have a non-complete response (NCR) will undergo TURBT of any remaining lesions and will then enter the follow-up period of the study.~During the follow-up period, patients will return to the clinic every 3 months to determine durability of response. Patients will remain on study until completion of all follow-up visits (approximately 24 months after the initiation of treatment) or until recurrence or death is documented, whichever occurs first. Patients determined to have a protocol-defined recurrence at any follow-up or unscheduled visit will be considered to have completed the study and released to the care of their treating physician.~The study is event-driven and patients may be followed beyond 24 months or additional patients may be enrolled to achieve the target number of events required for the study.
This is a global, randomized, controlled, open-label Phase 3 study designed to assess the long-term efficacy and safety of UGN-102 (mitomycin) for intravesical solution with or without (±) transurethral resection of bladder tumors (TURBT) versus TURBT alone for the treatment of patients with low grade intermediate risk non-muscle-invasive bladder cancer (LG IR NMIBC).
