UroGen Pharma Reports Second Quarter 2022 Financial Results and Recent Corporate Developments

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, 2022 and provided an overview of recent developments.

"Positive momentum established last quarter has accelerated into the second quarter of 2022 and we remain confidently on track to meet our anticipated guidance, both financial and in terms of clinical development," said Liz Barrett, President, and Chief Executive Officer of UroGen. "Jelmyto adoption continues to grow and real-world evidence supports the use of our medicine for LG-UTUC patients. The use of in-office nephrostomy tube administration has grown and data on the potential benefits of this alternate mode of administration was presented at the American Urological Association meeting in May. Enrollment in the Phase 3 ENVISION pivotal trial of UGN-102 in low-grade, intermediate-risk NMIBC is on pace for completion by year-end, while our Phase 1 clinical study of UGN-301 in high-grade NMIBC is well underway. With intent to provide reassurance in this challenging capital market environment, we are continuously assessing the strategic and efficient deployment of capital across our operations and have made a modest reduction to our operating expense forecast. We remain focused towards our goal of reaching cash flow break-even in 2025 while not compromising the success of Jelmyto and UGN-102 as well as our long-term growth potential. We will remain flexible and opportunistic and continuously evaluate new and current levers in the event we find a need to conserve or access additional working capital."

Business Highlights:

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

• Generated net product revenues of $16.6 million for the second quarter of 2022, representing a 22% increase over the first quarter of 2022, and a 28% increase over the same period in 2021.
• Activated sites on August 1 were 893, compared to 857 on May 1, 2022 while repeat accounts on August 1 were 144, compared to 114 on May 1, 2022.
• Nephrostomy tube administration of Jelmyto has increased from approximately 20% to approximately 40% of instillations over the past 3 months, benefits of which include avoiding the necessity of medical equipment as well as conferring more flexibility with scheduling and instillation.
• Empirical data of Jelmyto instillation via Nephrostomy were presented at the American Urological Association meeting in May by Dr. Kyle Rose demonstrating that 13 of 26 patients examined exhibited a complete response, while another 12 patients had a partial response. Importantly, ureteral stenosis occurred in 4 (15%) patients, compared to 31 (44%) patients in the pivotal OLYMPUS trial, where all participants were administered Jelmyto via retrograde administration. There were no severe adverse events reported and no patients had impaired renal function.

UGN-102 (mitomycin) for intravesical solution:

• Enrollment ongoing and active in the single-arm Phase 3 ENVISION pivotal trial of UGN-102 for the treatment of LG-IR-NMIBC. Completion of enrollment continues to be anticipated by the end of 2022.
• ENVISION is similar in design to the previously completed Phase 2b OPTIMA II study which demonstrated a complete response (CR) rate of 65% and probability of remaining in CR 12 months after therapy of 72.5% by Kaplan Meier analysis. UroGen continues to anticipate submitting a New Drug Application (NDA) to the FDA for UGN-102 in 2024.

UGN-301 (zalifrelimab) for intravesical solution:

• UroGen's first-in-human, novel, multi-arm Phase 1 clinical trial of UGN-301, the Company's anti-CTLA4 antibody, in HG-NMIBC is ongoing. 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.

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 LG IR NMIBC

Out of the 80,000 estimated cases of bladder cancer per year in the U.S., approximately 35,000 are low-grade NMIBC patients comprised of both low-risk (approximately 15,000) and intermediate risk (approximately 20,000). These patients face a future of recurrence and additional surgeries. Recurrence in low-grade intermediate-risk NMIBC is pervasive and often underestimated. In patients who recur, approximately 68 percent will experience two or more recurrence episodes throughout the course of their disease, a high and frequent rate in contrast to other non-metastatic cancers. Currently, the only effective primary treatment available is a surgical procedure known as transurethral resection of bladder tumor, or TURBT. Every time TURBT is performed it imposes more burden and serious risks on patients. Approximately 25 percent of patients are not appropriate for TURBT, whether due to physical factors such as age and comorbidities or an unwillingness to undergo surgery.

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.
