UroGen Announces Agreement Resolving Patent Litigation Relating to JELMYTO (mitomycin) for pyelocalyceal solution

• Agreement reinforces the value of UroGen’s innovation and reflects the strength of the Company’s intellectual property portfolio
• Teva will be granted a non-exclusive license to sell its generic version of JELMYTO beginning on September 15, 2030, if approved by the FDA

PRINCETON, N.J., June 02, 2026 (GLOBE NEWSWIRE) -- UroGen Pharma Ltd. (Nasdaq: URGN), a biotechnology company dedicated to developing and commercializing innovative solutions that treat urothelial and specialty cancers, today announced that it has entered into a settlement and license agreement (the “Agreement”’) with Teva Pharmaceuticals, Inc. and Teva Pharmaceuticals, USA, Inc. (collectively, “Teva”). This Agreement resolves the patent litigation UroGen initiated in response to Teva’s submission of an Abbreviated New Drug Application (ANDA) to the U.S. Food and Drug Administration (“FDA”) seeking approval to market a generic version of JELMYTO® (mitomycin) for pyelocalyceal solution prior to the expiration of the relevant Company patents. Please note, that the Teva ANDA has not received tentative approval from the FDA, according to the Agency’s public database.

Under the terms of the Agreement, UroGen will grant Teva a non-exclusive license to sell its generic version of JELMYTO beginning on September 15, 2030, if approved by the FDA, unless certain limited circumstances customarily included in these types of agreements occur. In accordance with the Agreement, the parties will ask the court to dismiss the pending patent litigation with prejudice.

“We believe this resolution underscores the innovation behind our RTGel^® technology and the strength of our intellectual property portfolio,” said Liz Barrett, President and Chief Executive Officer of UroGen. “We look forward to continuing to execute on our mission to transform paradigms in uro-oncology with our innovative treatments.”

JELMYTO has regulatory exclusivity through April 15, 2027, and is covered by Orange Book-listed patents expiring on January 20, 2031. The negotiated license date preserves nearly all of this patent protection period, reflecting the strength of the Company’s intellectual property.

As required by law, the companies will submit the Agreement to the U.S. Federal Trade Commission and U.S. Department of Justice for review.

About JELMYTO

JELMYTO^® (mitomycin) for pyelocalyceal solution is a mitomycin-containing reverse thermal gel containing 4 mg mitomycin per mL gel approved 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 a 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.

About Upper Tract Urothelial Cancer

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 LG-UTUC patients annually. Most cases are diagnosed in patients over 70 years old, and these older patients often have multiple comorbidities. There are limited treatment options for UTUC, with the most common being endoscopic surgery or nephroureterectomy (removal of the entire kidney and ureter). Treatment with endoscopic surgery can be associated with a high rate of recurrence and relapse.

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 is approved to treat low-grade upper tract urothelial cancer, and our second product is approved for adult patients with recurrent LG-IR-NMIBC. Both products are designed to ablate tumors by non-surgical means. UroGen is headquartered in Princeton, NJ with operations in Israel.

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.

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.

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.
