On May 21, 2025 UroGen Pharma Ltd. (Nasdaq: URGN), a leading biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, reported the outcome of today’s meeting of the Oncologic Drugs Advisory Committee (ODAC) of the U.S. Food and Drug Administration (FDA), which discussed the new drug application (NDA) for investigational drug UGN-102 (mitomycin) for intravesical solution (Press release, UroGen Pharma, MAY 21, 2025, View Source [SID1234653276]). By a narrow margin, the ODAC voted 4 to 5 that the benefit/risk of UGN-102 (mitomycin) for intravesical solution was favorable for the treatment of recurrent LG-IR-NMIBC.

"While we are disappointed by today’s outcome, we continue to believe our clinical data support UGN-102 for the treatment of recurrent LG-IR-NMIBC, a disease with no FDA-approved therapies," said Liz Barrett, President and CEO of UroGen. "The FDA carefully considers the independent advice from ODAC, and we look forward to working with the FDA as they complete their review of the application for UGN-102."

The ODAC reviewed the body of clinical data supporting the efficacy and safety of UGN-102, including the results from the Phase 3 ENVISION study. "Low-grade intermediate-risk non-muscle invasive bladder cancer is a highly recurrent disease and often requires patients – many of whom are elderly – to undergo repeat surgeries under general anesthesia. This is a disease with high unmet needs, and we believe patients deserve more options," said Mark Schoenberg, M.D., Chief Medical Officer, UroGen. "UroGen remains committed to developing innovative treatment options to people living with recurrent LG-IR-NIMBC."

The most common treatment-emergent adverse events in the ENVISION trial were dysuria, hematuria, urinary tract infection, pollakiuria, fatigue, and urinary retention, which are typically manageable in routine urologic practice. The ENVISION trial demonstrated a similar safety profile to that observed in other studies of UGN-102.

The NDA for UGN-102 is currently under review by the FDA with a Prescription Drug User Fee Act (PDUFA) date of June 13, 2025.

About UGN-102

UGN-102 (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, currently in Phase 3 development for the treatment of recurrent 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 by a trained healthcare professional. UroGen completed the submission of the rolling NDA for UGN-102 in August 2024, ahead of schedule. The FDA accepted the NDA for UGN-102 and assigned a PDUFA target action date of June 13, 2025.

About Non-Muscle Invasive Bladder Cancer (NMIBC)

LG-IR-NMIBC affects around 82,000 people in the U.S. every year and of those, an estimated 59,000 are recurrent. Bladder cancer primarily affects older populations with increased risk of comorbidities, with the median age of diagnosis being 73 years. Guideline recommendations for the management of NMIBC include trans-urethral resection of bladder tumor (TURBT) as the standard of care. Up to 70 percent of NMIBC patients experience at least one recurrence and LG-IR-NMIBC patients are even more likely to recur and face repeated TURBT procedures.

About ENVISION

The Phase 3 ENVISION trial is a single-arm, multinational, multicenter pivotal study evaluating the efficacy and safety of UGN-102 (mitomycin) for intravesical solution as a chemoablative therapy in patients with LG-IR-NMIBC. The Phase 3 ENVISION trial completed target enrollment with 240 patients across 56 sites. Study participants received six once-weekly intravesical instillations of UGN-102. The primary endpoint evaluated the CR rate at three months after the first instillation, and the key secondary endpoint evaluated durability over time in patients who achieved a CR at the three-month assessment.
