PRINCETON, N.J. / Aug 13, 2024 / Business Wire / 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, 2024, and provided an overview of recent developments.

“Our immediate priority is completing the submission of a New Drug Application in the very near term for UGN-102, which we believe has the potential to be a practice-changing therapy for the treatment of low-grade intermediate-risk non-muscle invasive bladder cancer,” said Liz Barrett, President and Chief Executive Officer of UroGen. “The compelling body of clinical data, including the ENVISION trial, which demonstrated an unprecedented 82.3% 12-month duration of response by Kaplan-Meier analysis in patients who had previously achieved a complete response at three months, reinforces the opportunity for UGN-102 to be the first FDA-approved medicine for the treatment of low-grade intermediate-risk non-muscle invasive bladder cancer.”

Ms. Barrett continued, “We estimate that approximately 82,000 patients suffering from this highly recurrent disease each year may benefit from an innovative treatment, creating an estimated five-billion-dollar market opportunity. Our immediate commercial focus is preparing for UGN-102’s potential approval and launch with the goal to establish our leadership in urothelial cancers.”

Q2 2024 and Recent Business Highlights:

UGN-102 (mitomycin) for intravesical solution:

• In June 2024, UroGen reported positive 12-month duration of response (DOR) data from the Phase 3 ENVISION pivotal trial evaluating UGN-102 (mitomycin) for intravesical solution in patients with low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC). The 12-month DOR was 82.3% (95% CI, 75.9%, 87.1%) by Kaplan-Meier estimate in patients who had achieved complete response (CR) at three months from the first instillation of investigational drug UGN-102. The ENVISION trial previously met its primary endpoint by demonstrating that patients treated with UGN-102 had a 79.6% (95% CI, 73.9%, 84.5%) CR rate at three months following the first instillation of UGN-102. UGN-102 was well tolerated, with a safety profile that was consistent with previous clinical trials.

• The ENVISION 12-month DOR data were presented in a virtual event “New Horizons in Bladder Cancer” hosted by UroGen on June 13. This event included presentations by company management and several key opinion leaders with expertise in urology. There was also a panel discussion on the treatment of LG-IR-NMIBC and insights from a patient from the ENVISION trial. A replay of the event can be accessed here.

• The latest DOR data is expected to support a New Drug Application (NDA) for UGN-102 as a treatment for LG-IR-NMIBC, which the Company plans to complete in the very near term. There is potential for an FDA decision as early as the first quarter of 2025, assuming the FDA grants priority review. UroGen initiated submission of the rolling NDA for UGN-102 in January 2024.

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

• Generated net product revenue of $21.8 million in the second quarter of 2024, compared to $21.1 million in the second quarter of 2023.

• 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 showed that JELMYTO treatment appears to demonstrate favorable recurrence-free survival rates for patients with LG-UTUC who respond to initial induction. There does not appear to be a recurrence difference according to the intent of JELMYTO induction, original tumor size, multifocality or tumor location.

Next-generation novel mitomycin-based formulation for urothelial cancers

• UroGen is developing UGN-103 and UGN-104, next-generation novel mitomycin-based formulations for UGN-102 and JELMYTO, respectively. These candidates combine UroGen’s RTGel® technology with a novel mitomycin formulation licensed from medac GmbH in an agreement signed in January 2024. The development programs potentially offer both manufacturing efficiencies and additional intellectual property protection for the Company’s low-grade urothelial cancer franchise.

• In April 2024, the U.S. 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 has initiated the Phase 3 study and has onboarded three clinical sites to explore the safety and efficacy of UGN-103 in LG-IR-NMIBC. UroGen plans to initiate a Phase 3 study of UGN-104 in LG-UTUC early next year.

Corporate

• In June 2024, UroGen appointed David Lin as Chief Commercial Officer and member of the Executive Leadership Team. Mr. Lin is spearheading UroGen’s commercial strategy and will be leveraging his extensive experience to prepare for the potential launch of UGN-102, if approved.

Public offering of ordinary shares and pre-funded warrants

• In June 2024, the Company completed an underwritten public offering of 5,000,000 ordinary shares at a price to the public of $17.50 per ordinary share, and, to certain investors in lieu of issuing ordinary shares, pre-funded warrants to purchase 1,142,857 ordinary shares at a purchase price of $17.499 per pre-funded warrant, which equals the public offering price per ordinary share less the $0.001 per share exercise price for each pre-funded warrant. Gross proceeds to UroGen from the offering, before deducting underwriting discounts and commissions and estimated offering expenses, were approximately $107.5 million.

• In July 2024 the underwriters exercised their option to purchase the full 921,428 additional shares. This yielded further gross proceeds to the Company of $16.1 million, before deducting underwriting discounts and commissions and estimated offering expenses.

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.

• 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.

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.
