• Full enrollment of ENVISION Phase 3 pivotal trial with UGN-102 in low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC) expected as soon as the end of November 2022; NDA submission anticipated in first half of 2024
• Reported JELMYTO® net product revenue of $16.1 million, an increase of 41% from the same period last year
• FDA authorized extension of the in-use period for JELMYTO^® admixture from 8 to 96 hours following reconstitution further simplifying workflow for urologists

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 third quarter ended September 30, 2022, and provided an overview of recent developments.

“From a consistent vision to pipeline advancement and product commercialization, we remain highly encouraged by the inroads we have made creating a new market in how urologic cancers are treated. Despite slightly lower revenue compared to the previous quarter, JELMYTO’s favorable growth trends, which include a substantial increase of year-over-year net product revenues, new site activations, and recent real-world outcomes data, continues to give us confidence in the LG-UTUC opportunity as we work to replicate the success we’ve had in certain key markets,” said Liz Barrett, President and Chief Executive Officer of UroGen. “We anticipate that the FDA authorization this quarter to extend JELMYTO’s in-use period for the admixture from 8 hours to 96 hours following reconstitution will provide yet another significant opportunity towards driving market adoption and expansion.”

“In parallel, we are rapidly advancing perhaps the most exciting investigational product in our pipeline, UGN-102, which has the potential to transform the treatment of bladder cancer and significantly broaden the utilization of our RTGel™ reverse-thermal hydrogel technology,” continued Ms. Barrett. “ENVISION, our Phase 3 pivotal trial of UGN-102 in LG-IR-NMIBC, is on pace to complete enrollment as soon as the end of the month, bringing us one step closer to realizing UGN-102’s potential as the first non-surgical primary therapeutic to treat this important subset of bladder cancer patients. As we advance each of these programs, as well as our broader portfolio, we continue a disciplined and balanced approach to capital preservation in support of growing our business and maintaining a strong balance sheet.”

Business Highlights:

Jelmyto (mitomycin) for pyelocalyceal solution in low-grade Upper Tract Urothelial Cancer (LG-UTUC):

• Reported net product revenue of JELMYTO for the third quarter 2022 of $16.1 million, compared to $11.4 million in the third quarter of 2021, representing an increase of 41% from the same period last year.
• Activated sites and repeat accounts as of November 1 were 930 and 177, respectively as compared to 893 and 144 on August 1, 2022.
• FDA authorized an extension of the in-use period for JELMYTO admixture from 8 hours to 96 hours following reconstitution. This extension expands access to JELMYTO and gives urologists greater flexibility in choosing when to reconstitute and schedule instillations, including early morning instillation which we estimate is preferred by nearly all prescribing HCPs.
• A multi-center retrospective analysis published in the British Journal of Urology International by Kyle Rose, M.D. Society of Urologic Oncology Fellow, Moffitt Cancer Center, and colleagues showed that 17 of 32 (59%) patients who received JELMYTO via antegrade administration had no evidence of disease at the primary disease evaluation and did not recur at a median follow up of 13 months. Importantly, ureteral stenosis occurred in just 3 (9%) of treated patients. This retrospective analysis concluded that antegrade administration of JELMYTO demonstrated a favorable safety profile, including a low rate of ureteral stenosis and can be administered without general anesthesia.

UGN-102 (mitomycin) for intravesical solution:

• Full enrollment of approximately 220 patients across 90 sites in the single-arm Phase 3 ENVISION pivotal trial of UGN-102, for the treatment of low-grade, intermediate-risk NMIBC is expected to be completed as soon as the end of November 2022.
• Hosted thought-leader webinar on UGN-102 and non-muscle invasive bladder cancers on October 18, 2022, which underscored the magnitude of the patient population and high unmet need in LG-IR-NMIBC.

UGN-301 (zalifrelimab) for intravesical solution:

• UroGen continues to enroll subjects for its first-in-human, novel, multi-arm Phase 1 clinical trial of UGN-301, the Company’s anti-CTLA4- antibody, in high-grade NMIBC.
• This Phase 1 clinical trial will utilize a Master Protocol to evaluate the safety and tolerability of UGN-301 as monotherapy and in combination with other immunomodulators, including UGN-201, the Company’s proprietary toll-like receptor 7 (TLR7) agonist, as well as other potential chemo and/or immune therapies in patients with NMIBC.

Board of Directors Appointments

• Announced the appointment of two new independent members to the Board of Directors: Dr. Leana S. Wen, an emergency medicine physician and public health policy expert, and Dan Wildman, a seasoned executive with more than forty years of Medical Device and Pharmaceutical industry experience developing and commercializing meaningful innovations that changed the standard of care, including Auris Heath’s (a division of Ethicon Inc.) Monarch robotic surgery system

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 RTGelTM 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 is expected to enroll approximately 220 patients across 90 sites and 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 enrollment expected by the end of 2022, assuming positive findings, UroGen anticipates submitting an NDA for UGN-102 in 2024.
