• Reported JELMYTO^® Q1 2023 net product revenues of $17.2 million, an increase of ~27% from Q1 2022
• Complete Response data from ENVISION pivotal trial and topline data readout from ATLAS trial on track for summer 2023

PRINCETON, N.J. / May 11, 2023 / 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 first quarter ended March 31, 2023, and provided an overview of recent developments.

“2023 is off to a promising start as we reported double-digit year-over-year growth in worldwide JELMYTO net sales during the first quarter,” said Liz Barrett, President, and Chief Executive Officer of UroGen. “JELMYTO adoption continues to grow, attributable to the growing body of evidence supporting its benefits in a real-world setting, combined with key initiatives that have expanded access and improved logistical efficiencies for physicians and patients. As we look ahead to summer 2023, we have several key events to prepare for, primarily topline results from both the ENVISION and ATLAS clinical trials investigating the potential of UGN-102 for the treatment of LG-IR-NMIBC. With prospective favorable results, we will look to submit a New Drug Application (NDA) for UGN-102 in 2024 to the U.S. Food & Drug Administration (FDA), for which we are already actively preparing.”

Business Highlights:

UGN-102 (mitomycin) for intravesical solution:

• A topline data readout of the primary endpoint from the ENVISION Phase 3 pivotal study of UGN-102 evaluating the complete response (CR) rate of ~240 patients at 3-months after first instillation is expected this summer.
• Topline data from the ATLAS clinical trial, the predecessor to ENVISION, is expected summer 2023 and will evaluate complete response, duration of response and safety from ~280 patients that completed the trial.
• Announced preliminary results of a study to assess the feasibility of home instillation of UGN-102. In this study, UGN-102 was suitable to administer at home by a visiting nurse under the supervision of a treating physician and resulted in 75% (n=8) of patients achieving a complete response, defined as no detectable disease 3 months after starting treatment.

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

• Generated net product revenue of $17.2 million for the first quarter of 2023, representing ~27% growth over the first quarter of 2022.
• Activated sites on May 1, 2023 were 1,009, compared to 983 on March 1, 2023, while repeat accounts on May 1, 2023 were 235, compared to 214 on March 1, 2023.
• A positive American Urologic Association (AUA) meeting was headlined by the first ever AUA and Society of Urologic Oncology (SUO) treatment guideline for LG-UTUC, recommending use of JELMYTO in certain clinical scenarios. The guideline states that tumor ablation should be the initial management option for patients with low-risk favorable UTUC, for which JELMYTO can be a treatment option as part of a kidney sparing approach intended to prevent radical nephroureterectomies (RNU) in low-risk UTUC patients.
• New retrospective study presented at AUA 2023 reported on the use of JELMYTO in treating patients with UTUC after complete endoscopic ablation. Patients in this retrospective study who underwent complete endoscopic ablation followed by JELMYTO were more likely to be disease-free at first endoscopic evaluation than those who underwent chemoablation alone (69% vs. 40%). In the Phase 3 OLYMPUS study of JELMYTO, LG-UTUC patients in the primary chemoablation setting achieved a 58% complete response rate at first endoscopic evaluation.
• New retrospective study presented at AUA 2023 reported similar outcomes when utilizing Jelmyto in treating LG-UTUC of the ureter compared to renal pelvic cancers. In this analysis, 47 patients had UTUC tumors involving the ureter, with 12 cases of ureteral tumor only (8.8%) and 35 cases of ureteral plus renal pelvic tumors (25.7%). The investigators reported no difference in outcomes at first endoscopic evaluation based on tumor location (p=0.644). JELMYTO is approved for the chemoablation of low-grade upper tract urothelial cancer (LG-UTUC) involving the renal pelvis and calyces.

About Jelmyto®

JELMYTO® (mitomycin) for pyelocalyceal solution is a mitomycin-containing reverse thermal gel containing 4 mg mitomycin per mL gel indicated for primary chemoablative treatment of LG-UTUC in adults. 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.

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 investigational drug formulation of mitomycin in Phase 3 development for the treatment of low-grade intermediate risk NMIBC. Utilizing the RTGel^® Technology Platform, UroGen’s proprietary 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. The Company presented results from the Phase 2b OPTIMA II trial in September 2021.

About the Phase 3 ENVISION Trial

The Phase 3 ENVISION trial is a single-arm, multinational, multicenter study evaluating the efficacy and safety of UGN-102 (mitomycin) as primary chemoablative therapy in patients with low-grade, intermediate-risk NMIBC. The Phase 3 ENVISION trial completed target enrollment with approximately 240 patients across 90 sites. Study participants will receive six once-weekly intravesical instillations of UGN-102. The planned primary endpoint will evaluate the complete response rate at three months after the first installation, and the key secondary endpoint will evaluate durability over time in patients who achieve complete response at the three-month assessment. Based on discussions with the FDA, and assuming positive findings, UroGen anticipates submitting an NDA for UGN-102 in 2024.
