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 fourth quarter and full year ended December 31, 2024, and provided an overview of recent developments.

“2024 was a pivotal year for UroGen with achievements across our commercial business and pipeline,” said Liz Barrett, President and Chief Executive Officer of UroGen. “The progress with UGN-102 for low-grade intermediate-risk non-muscle invasive bladder cancer, including completion of the submission of our NDA ahead of schedule and compelling DOR data from the Phase 3 ENVISION trial, further positions us to launch a product that we believe will represent a paradigm shift in care, if approved. UGN-102 is supported by a compelling body of clinical data, and we are very pleased to report today the 18-month DOR of 80.6% from the ENVISION trial, maintaining duration of response consistent with 12-month DOR of 82.5% after a three-month CR was achieved. If approved, UGN-102 will address an estimated market opportunity of over $5 billion. We continue to advance our early-stage pipeline, including through the recent purchase of ICVB-1042, a next generation investigational oncolytic virus therapy with potential applications in bladder and other cancers.”

2024 and Recent Business Highlights:

UGN-102 (mitomycin) for intravesical solution:

• UroGen’s NDA for investigational drug UGN-102 (mitomycin) for intravesical solution as a treatment for low-grade intermediate risk non-muscle invasive bladder cancer (LG-IR-NMIBC), is currently under review by the FDA. The FDA assigned a PDUFA target action date of June 13, 2025.
• The Company reported updated 18-month DOR data from the Phase 3 ENVISION trial that evaluated UGN-102 in patients with LG-IR-NMIBC. The 18-month DOR data is consistent with prior Kaplan-Meier estimates, with a DOR rate of 80.6% (95% CI: 74.0, 85.7) at 18-months (N=101) compared to 82.5% (95% CI: 76.1, 87.3) at 12-months (N=146). Median follow-up time at 18 months was 18.7 months after the three-month CR.
• Results from a subgroup analysis of the ENVISION trial were featured in a poster at the American Society of Clinical Oncology’s Genitourinary Cancers Symposium (ASCO-GU 2025) in February 2025. The analysis of pre-specified subgroups (presented by Sandip M Prasad, MD, MPhil et al) suggests that tumor burden and the number of tumors at baseline did not significantly affect the CR rate or DOR for patients treated with UGN-102.

JELMYTO (mitomycin) for pyelocalyceal solution in low-grade upper tract urothelial cancer (LG-UTUC):

• Generated net product revenue of $90.4 million and $82.7 million for the years ended December 31, 2024 and 2023, respectively. Underlying demand revenue increased 12% year-over-year, partially offset by a decrease in CREATES Act sales, which totaled $3.0 million in 2024 compared to $4.4 million in 2023. “New prescribers” and “new patient” starts increased 33% and 13%, respectively, in 2024.
• A long-term study on JELMYTO titled, “Durability of Response of UGN-101: Longitudinal Follow-Up of Multicenter Study,” was published online in Urologic Oncology: Seminars and Investigations in January 2025. The results showed 68% recurrence-free survival rate at three years across a broad patient population with LG-UTUC.
• A long-term follow-up study to the OLYMPUS trial evaluating JELMYTO was presented at the Society for Urologic Oncology annual meeting in December 2024. The study reported a median DOR of 47.8 months in patients who achieved a CR after primary chemoablation with JELMYTO. These results were also published online in the Journal of Urology.

Next-generation novel mitomycin-based formulation for urothelial cancers

• Enrollment is ongoing in the Phase 3 UTOPIA trial of investigational drug UGN-103 (mitomycin) for intravesical solution in patients with LG-IR-NMIBC. UGN-103 is a next generation investigational medicine that combines UroGen’s RTGel^® technology with a novel mitomycin formulation licensed from medac GmbH. UGN-103 is planned to follow the potential FDA approval and launch of UGN-102 for LG-IR-NMIBC. To learn more about the UTOPIA trial, refer to clinicaltrials.gov/NCT06331299.
• UroGen plans to initiate a Phase 3 trial to explore the safety and efficacy of UGN-104, its next generation product for LG-UTUC in the first half of 2025.

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

• Completed enrollment of 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.

Next-generation investigational oncolytic virus ICVB-1042

• In February 2025, UroGen expanded its pre-clinical oncology portfolio with the purchase of the product candidate ICVB-1042 and certain related assets from IconOVir Bio, Inc. ICVB-1042 is being developed to be a potent, fast-replicating, next-generation oncolytic virus therapy that can be administered locally to treat bladder cancer and potentially other specialty cancers. UroGen hosted a webinar to discuss ICVB-1042 on February 20, 2025 and a replay can be accessed on the Company’s website here.

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. Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with JELMYTO. Females who are able to become pregnant: You should use effective birth control (contraception) during treatment with JELMYTO and for 6 months after the last dose. Males being treated with JELMYTO: If you have a female partner who is able to become pregnant, you should use effective birth control (contraception) during treatment with JELMYTO and for 3 months after the last dose.
• are breastfeeding or plan to breastfeed. It is not known if JELMYTO passes into your breast milk. Do not breastfeed during treatment with JELMYTO and for 1 week after the last dose.
• Tell your healthcare provider if you take water pills (diuretic).

How will I receive JELMYTO?

• Your healthcare provider will tell you to take a medicine called sodium bicarbonate before each JELMYTO treatment.
• You will receive your JELMYTO dose from your healthcare provider 1 time a week for 6 weeks. It is important that you receive all 6 doses of JELMYTO according to your healthcare provider’s instructions. If you miss any appointments, call your healthcare provider as soon as possible to reschedule your appointment. Your healthcare provider may recommend up to an additional 11 monthly doses.
• JELMYTO is given to your kidney through a tube called a catheter.
• During treatment with JELMYTO, your healthcare provider may tell you to take additional medicines or change how you take your current medicines.

After receiving JELMYTO:

• JELMYTO may cause your urine color to change to a violet to blue color. Avoid contact between your skin and urine for at least 6 hours.
• To urinate, males and females should sit on a toilet and flush the toilet several times after you use it. After going to the bathroom, wash your hands, your inner thighs, and genital area well with soap and water.
• Clothing that comes in contact with urine should be washed right away and washed separately from other clothing.

JELMYTO may cause serious side effects, including:

• Swelling and narrowing of the tube that carries urine from the kidney to the bladder (ureteric obstruction). If you develop swelling and narrowing, and to protect your kidney from damage, your healthcare provider may recommend the placement of a small plastic tube (stent) in the ureter to help the kidney drain. Tell your healthcare provider right away if you develop side pain or fever during treatment with JELMYTO.
• Bone marrow problems. JELMYTO can affect your bone marrow and can cause a decrease in your white blood cell, red blood cell, and platelet counts. Your healthcare provider will do blood tests prior to each treatment to check your blood cell counts during treatment with JELMYTO. Your healthcare provider may need to temporarily or permanently stop JELMYTO if you develop bone marrow problems during treatment with JELMYTO.
• The most common side effects of JELMYTO include: urinary tract infection, blood in your urine, side pain, nausea, trouble with urination, kidney problems, vomiting, tiredness, stomach (abdomen) pain.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1‑800‑FDA‑1088. You may also report side effects to UroGen Pharma at 1-855-987-6436.

About Upper Tract Urothelial Cancer (UTUC)

Urothelial cancer is the ninth most common cancer globally and the eighth most lethal neoplasm in men in the U.S. Between five percent and ten percent of primary urothelial cancers originate in the ureter or renal pelvis and are collectively referred to as UTUC. In the U.S., there are approximately 6,000 - 7,000 new or recurrent low-grade UTUC patients annually. Most cases are diagnosed in patients over 70 years old, and these older patients often face comorbidities. There are limited treatment options for UTUC, with the most common being endoscopic surgery or nephroureterectomy (removal of the entire kidney and ureter). These treatments can be associated with a high rate of recurrence and relapse.
