UroGen Announces New Data Presentations at the Society of Urologic Oncology 2024 Annual Meeting Highlighting Urothelial Cancer Portfolio Aimed at Addressing Unmet Needs

UroGen Pharma Ltd. (NASDAQ:URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced that new data on UGN-102 (mitomycin) for intravesical solution, JELMYTO (mitomycin) for pyelocalyceal solution, and UGN-301(zalifrelimab intravesical solution) will be presented at the Society of Urologic Oncology (SUO) 2024 annual meeting being held in Dallas, Texas from December 4 – 6.

"We are excited that the SUO has accepted data highlighting the potential of our investigational treatment, UGN-102, in development for patients with low-grade, intermediate-risk non-muscle-invasive bladder cancer (LG-IR-NMIBC), as well as the ongoing clinical value of JELMYTO for treating low-grade upper tract urothelial carcinoma (LG-UTUC)," said Mark Schoenberg, M.D., Chief Medical Officer of UroGen. "These presentations underscore our ongoing commitment to addressing the critical unmet needs of patients with urothelial cancers, as well as our mission to provide innovative treatment options that seek to improve both outcomes and quality of life for those battling these challenging conditions."

Key details of UGN-102, JELMYTO and UGN-301 abstracts accepted by SUO:

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 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 NDA submission in August, ahead of schedule. The FDA accepted the NDA for UGN-102 and assigned a PDUFA goal date of June 13, 2025.

About JELMYTO

JELMYTO® (mitomycin) for pyelocalyceal solution is a mitomycin-containing reverse thermal gel containing 4 mg mitomycin per mL gel indicated for the treatment of adult patients with LG-UTUC. It is recommended for primary treatment of biopsy-proven LG-UTUC in patients deemed appropriate candidates for renal-sparing therapy. JELMYTO is a viscous liquid when cooled and becomes a semi-solid gel at body temperature. The drug slowly dissolves over four to six hours after instillation and is removed from the urinary tract by normal urine flow and voiding. It is approved for administration in a retrograde manner via ureteral catheter or antegrade through nephrostomy tube. The delivery system allows the initial liquid to coat and conform to the upper urinary tract anatomy. The eventual semisolid gel allows for chemoablative therapy to remain in the collecting system for four to six hours without immediately being diluted or washed away by urine flow.

UGN-301

UGN-301 is our investigational, in-licensed, anti-CTLA-4 monoclonal antibody (zalifrelimab), prepared with reverse-thermal hydrogel for intravesical administration into the bladder. Intravesical administration of UGN-301 is designed to increase drug concentrations in the bladder without significant systemic exposure, potentially diminishing the systemic toxicity associated with CTLA-4 blockade. UroGen is evaluating UGN-301 as combination therapy for the intravesical treatment of high-grade NMIBC.

About UroGen Pharma Ltd.

UroGen is a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers because patients deserve better options. UroGen has developed RTGel® reverse-thermal hydrogel, a proprietary sustained-release, hydrogel-based platform technology that has the potential to improve the therapeutic profiles of existing drugs. UroGen's sustained release technology is designed to enable longer exposure of the urinary tract tissue to medications, making local therapy a potentially more effective treatment option. Our first product to treat LG-UTUC and investigational treatment UGN-102 (mitomycin) for intravesical solution for patients with low-grade non-muscle invasive bladder cancer are designed to ablate tumors by non-surgical means.
