PRINCETON, N.J. May 13, 2024— 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 first quarter ended March 31, 2024, and provided an overview of recent developments.

“In 2024 to date, UroGen has made excellent progress in both our commercial business and pipeline of innovative products designed to treat urothelial and specialty cancers,” said Liz Barrett, President, and Chief Executive Officer of UroGen. “The upcoming announcement of 12-month duration of response results from ENVISION will be a key clinical milestone and we expect the data to support completion of our NDA for UGN-102. Pre-launch activities are underway and we estimate that UGN-102 will address a more than $3 billion market opportunity. If approved, we believe this product will become the major growth driver for UroGen and could establish a new standard of care in LG-IR-NMIBC.”

Q1 2024 and Recent Business Highlights:

UGN-102 (mitomycin) for intravesical solution:

• In January 2024, UroGen initiated submission of a rolling New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for UGN-102 as a treatment of low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC). The company plans to complete the submission in Q3 2024 with a potential FDA decision as early as the first quarter of 2025.

• In May 2024, a subgroup analysis from the UGN-102 ATLAS trial was featured in a podium presentation at the American Urological Association (AUA) 2024 Annual Meeting in San Antonio, Texas. The analysis showed that patients with new and recurrent LG-IR-NMIBC treated with UGN-102 ± TURBT (trans urethral resection of bladder tumor) had high probabilities of remaining event-free for disease free survival (DFS) and high probabilities of remaining in complete response.

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

• A soon-to-be-published post-hoc analysis of the OLYMPUS trial assessed the long-term effects in treating LG-UTUC with JELMYTO. Of the 71 patients who enrolled in OLYMPUS, 41 achieved a complete-response and their health outcomes were tracked for up to 12 months. 20 of these patients remaining in CR enrolled in a 5-year rollover study. All 41 patients with an initial CR indicated a promising median duration of response of 47.8 months, based on a median follow-up of 28.1 months. In the 5-year rollover trial, 75% (N=15) showed no disease recurrence, indicating potential for extended disease-free periods.

• JELMYTO was featured in three presentations at the AUA 2024 Annual Meeting. Independent long-term real-world analyses explored use of the product in broad patient types and with different methods of administration. The results show that JELMYTO treatment demonstrated favorable recurrence free survival rates for patients with LG-UTUC who respond to initial induction. The results were consistent regardless of JELMYTO administration, original tumor size, multifocality or tumor location.

• Continued strong demand for Jelmyto with record patient enrollments forms. Generated net product revenue of $18.8 million in the first quarter of 2024, compared with $17.2 million in the first quarter of 2023, representing ~10% annual growth.

Next-generation novel mitomycin-based formulation for urothelial cancers

• In January 2024, UroGen announced a license and supply agreement with medac GmbH to develop a next-generation novel mitomycin-based formulation for urothelial cancers. UGN-103 and UGN-104 combine UroGen’s RTGel^® technology with medac’s licensed mitomycin formulation. The agreement and development program potentially offer both manufacturing efficiencies and IP protection for the Company’s next-generation urothelial cancer franchise.

• In April 2024, the FDA accepted the Company’s Investigational New Drug (IND) application for UGN-103. If approved, UGN-103 is expected to provide several advantages related to production, cost, supply, and product convenience.

• UroGen plans to initiate Phase 3 studies to explore the safety and efficacy of UGN-103 in LG-IR-NMIBC in 2024 and UGN-104 in LG-UTUC shortly thereafter.

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. 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 upper tract urothelial cancers (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 lead to a high rate of recurrence and relapse.

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 low-grade, intermediate-risk, non-muscle invasive bladder cancer (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. Assuming positive findings from the durability of response endpoint from the ENVISION Phase 3 study, UroGen anticipates completing its NDA submission for UGN-102 in September with a potential FDA decision as early as the first quarter of 2025.
