UroGen Announces FDA Acceptance of its New Drug Application for UGN-102

• PDUFA goal date set for June 13, 2025
• UGN-102 would be the first FDA-approved medicine for LG-IR-NMIBC, if approved

UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced U.S. Food and Drug Administration (FDA) acceptance of the New Drug Application (NDA) for investigational drug UGN-102 (mitomycin) for intravesical solution. UGN-102 could become the first FDA-approved medicine for the treatment of low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC). The FDA has assigned a Prescription Drug User Fee Act (PDUFA) goal date of June 13, 2025.

"The FDA acceptance of our NDA is a pivotal moment in our journey to bring UGN-102 to patients,” said Liz Barrett, President and Chief Executive Officer of UroGen. “UGN-102 could be the first FDA-approved medicine for LG-IR-NMIBC, offering a novel approach that could expand treatment options and address unmet needs. There is an urgent need for innovative solutions in this space, and we are dedicated to collaborating with the FDA as we prepare for a potential launch of UGN-102 in 2025.”

Dr. Mark Schoenberg, Chief Medical Officer of UroGen, stated, “The NDA for UGN-102 is backed by a robust data set demonstrating impressive durability of response across three clinical trials and a favorable safety profile. Notably, the ENVISION trial successfully met its primary endpoint, showing a 79.6% complete response rate at three months after the first instillation of UGN-102. Additionally, the latest results from that trial revealed an 82.3% 12-month duration of response by Kaplan-Meier estimate in patients who achieved a complete response at 3 months. The most common treatment-emergent adverse events in the ENVISION trial were dysuria, hematuria, urinary tract infection, pollakiuria, fatigue, and urinary retention. Additionally, the safety profile observed in the ENVISION trial was consistent with that seen in other studies of UGN-102. We believe that, if approved, UGN-102’s ability to achieve durable complete responses and potentially reduce recurrence rates while extending treatment-free intervals will represent a significant advance in managing LG-IR-NMIBC.”

About UGN-102

UGN-102 (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, currently under regulatory review for approval in 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 by a trained healthcare professional. An NDA for UGN-102 is currently under review by the FDA with a potential decision expected by June 13, 2025. The U.S. market for LG-IR-NMIBC that UGN-102 can address, if approved, is valued at approximately $5 billion.

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 LG-IR-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 CR rate at the three-month assessment after the first instillation, and the key secondary endpoint evaluated durability over time in patients who achieved a CR at the three-month assessment.

About Non-Muscle Invasive Bladder Cancer (NMIBC)

In the U.S. bladder cancer is the second most common urologic cancer in men. LG-IR-NMIBC represents approximately 22,000 newly diagnosed bladder cancer patients each year and an estimated 60,000 recurrences annually among patients diagnosed from previous years. Bladder cancer primarily affects older populations with the median age of diagnosis 73 years and an increased risk of comorbidities. Guideline recommendations for the management of NMIBC include 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.
