A Phase 3 Study of UGN-102 for Low Grade Intermediate Risk Non-Muscle Invasive Bladder Cancer — ATLAS  

Bladder Cancer Clinical Trial

Official title: A Randomized, Controlled, Open-Label Study of the Efficacy, Durability, and Safety of UGN-102 With or Without TURBT in Patients With Low Grade Intermediate Risk Non-Muscle Invasive Bladder Cancer (LG IR NMIBC)

Status Terminated

Clinical Trial Summary

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).

Clinical Trial Description

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 arm will receive 6 weekly intravesical instillations of UGN-102 and patients randomized to the TURBT alone arm will undergo TURBT. Patients in both treatment arms will return to the clinic at approximately 3 months after the start of treatment to determine response to treatment. Patients confirmed to have a complete response (CR) will receive no further treatment and will enter the Follow-up Period of the study. Patients confirmed to have a non-complete response (NCR) will undergo TURBT of any remaining lesions and 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 or until disease recurrence, disease progression, or death is documented, whichever occurs first. Patients determined to have a protocol-defined recurrence or progression at any follow-up or unscheduled visit will be considered to have completed the study and released to the care of their treating physician. Study enrollment was stopped early by the sponsor to pursue an alternative development strategy for UGN-102 in the treatment of bladder cancer. Patients who had consented at the time the trial terminated were permitted to continue, but follow-up was terminated once the last patient had been followed for 15 months after the start of treatment. ;
