PRINCETON, N.J. August 7, 2025-- UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced financial results for the second quarter ended June 30, 2025, and provided an overview of recent developments.

“The recent FDA approval of ZUSDURI for the treatment of adults with recurrent LG-IR-NMIBC represents a truly transformative milestone for patients and for UroGen, marking our evolution into a multi-product uro-oncology company and our leadership in the field,” said Liz Barrett, President and Chief Executive Officer of UroGen. “Our commercial team is enthusiastically executing the ZUSDURI launch plan as we scale the organization to address the estimated $5 billion+ market opportunity. JELMYTO (mitomycin) for pyelocalyceal solution, our treatment for low-grade upper tract urothelial carcinoma (LG-UTUC), continues to grow with strong underlying demand in the second quarter reflecting continued interest in this important therapy for patients. We are equally excited about the continued progress across our pipeline, including our next-generation mitomycin formulations and immuno-oncology candidates. With a solid balance sheet, we are well positioned to fully support the launch of ZUSDURI while advancing strategic business initiatives to drive sustained growth and innovation.”

Q2 2025 and Recent Business Highlights:

ZUSDURI (mitomycin) for intravesical solution:

●

On June 12, 2025, the U.S. Food and Drug Administration (FDA) approved ZUSDURI (formerly UGN-102), the first and only FDA-approved medication for adults with recurrent LG-IR-NMIBC.

●

Updated Duration of Response (DOR) data from the Phase 3 ENVISION trial evaluating ZUSDURI in patients with recurrent LG-IR-NMIBC demonstrate a probability of remaining in complete response (CR) of 72.2% (95% CI: 64.1%, 78.8%) by Kaplan-Meier estimate, at 24-months after achieving a CR at three-months. Median follow-up time at 24-months was 23.7 months after the three-month CR.

●

Five-year results from the long-term extension study of the Phase 2b OPTIMA II trial evaluating ZUSDURI in patients with newly diagnosed or recurrent LG-IR-NMIBC were published in the Journal of Clinical Genitourinary Cancer. Among the 17 patients who achieved a CR and entered the long-term extension study, the median DOR was approximately 3.5 years by Kaplan-Meier estimate. A copy of the paper can be found here.

JELMYTO (mitomycin) for pyelocalyceal solution in LG-UTUC:

●

Generated net product revenue of $24.2 million in the quarter ended June 30, 2025, an increase of 11% compared to the same quarter in 2024, driven by underlying demand growth of 7% and year-over-year price favorability.

●

JELMYTO is being evaluated in the uTRACT Registry, details of which were presented at the 2025 American Society of Clinical Oncology annual meeting in June 2025. This single-arm, multicenter, prospective and retrospective study is looking at real-world use of JELMYTO for adult patients with UTUC across the United States. Comprehensive data over a three-year period will be collected, with the goal of providing insights into treatment patterns, long-term outcomes, and patient safety in real-world settings.

Next-generation novel mitomycin-based formulations for urothelial cancers

●

Enrollment is now complete in the ongoing Phase 3 UTOPIA clinical trial of investigational drug UGN-103 (mitomycin) for intravesical solution in patients with recurrent LG-IR-NMIBC. UGN-103 is a next-generation product designed to offer improvements over ZUSDURI (mitomycin) for intravesical solution, including a shorter manufacturing process and simplified reconstitution procedure. It combines UroGen’s RTGel® technology with a novel mitomycin formulation licensed from medac GmbH. To learn more about the UTOPIA trial, refer to clinicaltrials.gov/NCT06331299.

●

A Phase 3 study to explore the safety and efficacy of UGN-104 has been initiated. UGN-104 is a next generation product for LG-UTUC. To learn more about this trial, refer to https://clinicaltrials.gov/study/NCT06774131.

UGN-301 (zalifrelimab), an anti-CTLA4 antibody for use in high-grade non-muscle invasive bladder cancer

●

Enrollment is complete in the dose escalation phase of UGN-301, alone and in combination with fixed dose UGN-201 or gemcitabine. The treatments demonstrated an acceptable safety profile and were generally well tolerated across dose levels. Responses were observed in both monotherapy and combination therapy arms, and patient follow-up is ongoing to further assess the durability of these responses.

Second Quarter 2025 Financial Results

JELMYTO Revenue: JELMYTO net product revenues were $24.2 million for the three months ended June 30, 2025, compared with $21.8 million for the same quarter of 2024. Year-over-year revenue growth of 11% was driven by underlying demand growth of 7% and price favorability.

Research & Development Expenses (R&D): R&D expenses for the second quarter of 2025 were $18.9 million, including non-cash share-based compensation expense of $0.4 million as compared to $15.4 million, including non-cash share-based compensation expense of $0.6 million, for the same period in 2024. The increase in R&D expenses of $3.5 million was primarily driven by higher manufacturing costs and costs associated with the Phase 3 UTOPIA trial for UGN-103, partially offset by lower clinical trial costs and regulatory expenses in connection with ZUSDURI.

Selling, General and Administrative Expenses (SG&A): SG&A expenses for the second quarter of 2025 were $43.2 million, including non-cash share-based compensation expense of $2.3 million. This compares to $30.1 million, including non-cash share-based compensation expense of $3.0 million, for the same period in 2024. The increase in SG&A expenses of $13.1 million was primarily driven by ZUSDURI commercial preparation activities as well as an increase in overall commercial operation costs.

Financing on Prepaid Forward Obligation: UroGen reported non-cash financing expense related to the prepaid forward obligation to RTW Investments of $4.6 million in the second quarter of 2025, compared to $5.8 million in the same period in 2024. The decrease was primarily driven by changes in underlying assumptions for remeasuring the effective rate.

Interest Expense on Long-Term Debt: Interest expense related to the $125 million term loan facility with funds managed by Pharmakon Advisors was $4.1 million in the second quarter of 2025, compared to $3.5 million in the same period in 2024. The increase was primarily attributable to the interest expense on the third tranche of the loan that was funded in September 2024.

Net Loss: UroGen reported a net loss of $49.9 million or ($1.05) per basic and diluted share in the second quarter of 2025 compared with a net loss of $33.4 million or ($0.82) per basic and diluted share in the same period in 2024.

Cash and Equivalents: As of June 30, 2025, cash, cash equivalents and marketable securities totaled $161.6 million.

For further details on the Company’s financials, refer to Form 10-Q, filed with the SEC.

2025 JELMYTO Revenue and Company Operating Expense Guidance: Guidance for full-year 2025 net product revenues for JELMYTO remains unchanged and is expected to be in the range of $94 to $98 million. This implies a year-over-year growth rate of approximately 8% to 12% over the $87.4 million in demand driven JELMYTO sales in 2024, which excludes the $3.0 million in CREATES Act sales reported in 2024. Continue to expect full-year 2025 operating expenses to be in the range of $215 to $225 million, including non-cash share-based compensation expense of $11 million to $14 million.

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.

APPROVED USE FOR JELMYTO

JELMYTO® is a prescription medicine used to treat adults with a type of cancer of the lining of the upper urinary tract including the kidney called low-grade Upper Tract Urothelial Cancer (LG-UTUC).

IMPORTANT SAFETY INFORMATION

You should not receive JELMYTO if you have a hole or tear (perforation) of your bladder or upper urinary tract.

Before receiving JELMYTO, tell your healthcare provider about all your medical conditions, including if you:

●

are pregnant or plan to become pregnant. JELMYTO can harm your unborn baby. You should not become pregnant during treatment with JELMYTO.
