UGN-102, in Development as the Potential First Non-Surgical Therapy for LG-IR-NMIBC, Met Primary Endpoints in Both Phase 3 ATLAS and ENVISION Clinical Trials - Seite 2

The Phase 3 ATLAS clinical trial, the predecessor to ENVISION, evaluated the efficacy, durability, and safety of UGN-102 with or without TURBT vs. TURBT alone in 282 patients with LG-IR-NMIBC. ENVISION evaluated the efficacy and safety of UGN-102 as a primary chemoablative therapy in 240 patients with LG-IR-NMIBC.

UGN-102 ATLAS & ENVISION Top-line Data Review

About UGN-102

UGN-102 (mitomycin) for intravesical solution is an investigational drug formulation of mitomycin in Phase 3 development for the treatment of LG-IR-NMIBC. Utilizing UroGen’s proprietary RTGel technology, a sustained release, hydrogel-based formulation, UGN-102 is designed to enable longer exposure of bladder tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. UGN-102 is delivered to patients using a standard urinary catheter in an outpatient setting. Assuming positive findings from the ENVISION Phase 3 study, UroGen anticipates submitting a New Drug Application (NDA) for UGN-102 in 2024. If approved, UGN-102 would be the first non-surgical primary therapeutic to treat a subset of bladder cancer characterized by high recurrence rates and multiple surgeries.

About ENVISION

The Phase 3 ENVISION trial is a single-arm, multinational, multicenter study evaluating the efficacy and safety of UGN-102 (mitomycin) for intravesical solution as primary chemoablative therapy in patients with low-grade, intermediate-risk NMIBC. The Phase 3 ENVISION trial completed target enrollment with approximately 240 patients across 56 sites. Study participants received six once-weekly intravesical instillations of UGN-102. The primary endpoint evaluated the complete response rate at the 3-month assessment after the first instillation, and the key secondary endpoint will evaluate durability over time in patients who achieved a complete response at the three-month assessment. Based on discussions with the FDA, and assuming positive findings, UroGen anticipates submitting an NDA for UGN-102 in 2024.
