UroGen Pharma Reports Highest Revenue Quarter and Significant Full Year 2022 Growth and Recent Corporate Developments

• Reported JELMYTO® full year 2022 net product revenues of $64.4 million, an increase of 34% from full year 2021
• Completed enrollment of the ENVISION Phase 3 pivotal clinical trial for UGN-102 for LG-IR-NMIBC
• Topline data readout from ATLAS clinical study and Complete Response from ENVISION pivotal study expected to be reported mid-year 2023

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 fourth quarter and full year ended December 31, 2022, and overview of recent developments.

“I’m proud of our progress in 2022 and encouraged by our pipeline advancement and expanded access to JELMYTO as we work to fundamentally change the treatment paradigm of urologic cancers,” said Liz Barrett, President and Chief Executive Officer of UroGen. “Last year was a marked year for our exciting investigational product, UGN-102, with the potential to transform the treatment of bladder cancer as the only non-surgical therapeutic for LG-IR-NMIBC. As we have shared many times, we believe UGN-102 could be a transformational product, and one that represents a significant opportunity to address the estimated 80,000 patients suffering from LG-IR-NMIBC in the U.S. each year. In 2022, we initiated and completed enrollment of ENVISION, our Phase 3 pivotal study of UGN-102, and more recently shared long-term follow up data from the previously completed OPTIMA II study, which showed a 24.4-month median time to recurrence in evaluable patients who completed the study. Topline data from the ATLAS and ENVISION trials are expected mid-year 2023, and assuming positive results, we remain on track to submit a New Drug Application (NDA) in 2024. Supported by a growing body of real-world outcomes data, we delivered our strongest ever JELMYTO net sales in Q4 helping propel ~34% full-year growth for fiscal 2022. Looking ahead, we remain confident in the long-term success of JELMYTO in low-grade upper tract urothelial cancer (LG-UTUC) and the significant market opportunity of UGN-102, if approved, to drive growth in the years ahead.”

Business Highlights:

UGN-102 (mitomycin) for intravesical solution:

• Announced full enrollment in Phase 3 ENVISION pivotal study of UGN-102 for the treatment of LG-IR-NMIBC, which targeted enrollment of ~220 patients across 90 sites. Assuming positive findings, UroGen anticipates submitting an NDA for UGN-102 in 2024. Topline results from the primary endpoint evaluating the complete response rate at 3-months after first instillation are expected mid-year 2023.
• Topline data from the ATLAS trial, the predecessor to ENVISION, is expected mid-year 2023 and will evaluate complete response, duration of response and safety from ~280 patients that completed the trial.
• Shared new long-term follow up data from the Phase 2b OPTIMA II study at the Annual Society of Urologic Oncology (SUO) Meeting demonstrating a median DOR of 24.4 months (10.1 to 30.7 months) with UGN-102 in 15 of 25 evaluable patients.
• 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):

• JELMYTO^® generated net product revenues of $18.1 million and $64.4 million for the fourth quarter and full year 2022, respectfully, compared to $16.2 million and $48.0 million for the same periods in 2021.
• Activated sites on March 1, 2023 were 983, compared to 930 on November 1, 2022, while repeat accounts on March 1, 2023 were 214, compared to 177 on November 1, 2022.
• Highlighted results from the first and largest post-commercial utilization review of JELMYTO published in Urologic Oncology: Seminars and Original Investigations. The study evaluated 132 patients from 15 high-volume academic and community centers and describes several uses of JELMYTO that differ from the pivotal OLYMPUS trial, including for the treatment of large tumors (>3cm in 15% of cases), high grade tumors (9% of cases), ureteral tumors (35% of cases), and as a valuable multimodal adjunct following complete endoscopic ablation. JELMYTO is not approved for the treatment of high-grade upper tract urothelial cancer.
• Shared new long-term follow up data from the OLYMPUS registration trial at the Annual Society of Urologic Oncology (SUO) Meeting demonstrating a median durability of response (DOR) of 28.9 months (14.6 to 47.6 months) with JELMYTO in 16 of 23 evaluable patients.
• Retrospective, multi-center study of 32 patients evaluating the safety of antegrade administration of JELMYTO was published in The British Journal of Urology International showing a favorable safety and tolerability profile for JELMYTO when administered via nephrostomy tube. At a median follow-up of 15 months following initiation of induction therapy, ureteral stenosis occurred in only three (9%) patients, with none having recurrent stenosis at a median 16-month follow-up.

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.

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 completed target enrollment of 220 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.
