UroGen Pharma Reports Third Quarter 2021 Financial Results and Recent Corporate Developments

• Shift to single-arm Phase 3 study for UGN-102 in bladder cancer streamlines pivotal study to form basis of FDA submission
• Jelmyto® net product revenue of $11.4 million for the third quarter of 2021; New patient starts in September and October outpace July and August by nearly 60%
• Conference call and webcast to be held today at 10:00 AM ET

UroGen Pharma Ltd. (Nasdaq: URGN), a biopharmaceutical company dedicated to building and commercializing novel solutions that treat urothelial and specialty cancers, today announced financial results for the third quarter ended September 30, 2021, and provided an overview of the Company’s recent developments.

“The third quarter of 2021 was one of continued progress at UroGen, both clinically and commercially,” said Liz Barrett, President and Chief Executive Officer of UroGen. “As we highlighted at our Spotlight Event last week, we will initiate a new single-arm Phase 3 study of UGN-102 in low-grade, intermediate-risk, non-muscle invasive bladder cancer. We believe this new design affords a higher probability of regulatory success for UGN-102 in patients with low-grade IR-NMIBC, while allowing us to remain on-track for a planned NDA submission in 2024.” She added, “Additionally, as we approach the close of 2021, we are pleased with the strong demand we’re seeing for Jelmyto. September and October marked our highest months ever for both new patient starts and patient enrollment forms. We look forward to a strong start to 2022, as we advance and grow our pipeline while furthering the adoption of Jelmyto with the goal of it becoming the standard of care for patients with low-grade UTUC.”

Business Highlights:

Jelmyto (mitomycin) for pyelocalyceal solution:

• Achieved highest-ever Patient Enrollment Forms and New Patient Starts in September and October 2021.
• UroGen generated net product revenue of $11.4 million for the third quarter of 2021, representing over 200% growth over the third quarter of 2020 (first full quarter of launch), this compares to $13.0 million in the second quarter of 2021.
• As of November 1, 2021, 706 sites have been activated, which means they have completed their internal processes and have treated or are ready to treat patients. This represents a 73% increase since August 1, 2021.
• Sites that have treated more than one patient as of November 1, 2021, increased to 86, compared to 63 as of August 1, 2021: an increase of approximately 37%.

UGN-102 (mitomycin) for intravesical solution:

• Following discussions with the U.S. Food & Drug Administration (FDA), the Company announced plans to conduct a new single-arm Phase 3 study of UGN-102 for the treatment of low-grade, intermediate risk non-muscle invasive bladder cancer (LG-IR-NMIBC). The trial, which is expected to initiate in early 2022, will be similar in design to the Company’s previous OPTIMA II study. Based on the results of the OPTIMA II study, the Company believes this new trial carries a high probability of demonstrating a significant benefit for patients.
• Based on the planned initiation of this new Phase 3 study of UGN-102, the Company has ceased enrollment in the ATLAS Phase 3 trial of UGN-102 in LG-IR-NMIBC. The Company plans to complete ongoing treatments and follow up for all patients currently enrolled in the therapy arm. Safety data from the ATLAS study is expected to be included in a planned regulatory submission for UGN-102.

UGN-301:

• Preclinical studies conducted to-date suggest that bladder cancer treated with a combination of TLR-7 agonist and an anti-CTLA4 antibody in RTGel, produces improved survival compared to treatment with other checkpoint inhibitors in RTGel, either alone or in combination with UGN-201.
• Non-human primate toxicity studies underway to facilitate the initiation of a multi-arm Phase 1 study of UGN-301 in combination with other agents.
• First-in-human study planned to start in the first half of 2022.

Geographic expansion:

• Initiated a named-patient access program for Jelmyto in France, Germany, Switzerland, Austria and the UK.

Third Quarter 2021 Financial Results:

Jelmyto Revenue: UroGen reported net product revenue of Jelmyto for the third quarter ended September 30, 2021 of $11.4 million. Net product revenue was $31.9 million for the first three quarters of 2021 compared to $3.8 million for the same period in 2020 due to the launch of Jelmyto in June 2020.

R&D Expense: Research and development expenses for the third quarter ended September 30, 2021 were $11.9 million, including non-cash share-based compensation expense of $1.0 million. This compares to $10.2 million, including non-cash share-based compensation expense of $1.5 million, for the same period in 2020. The increase of $1.7 million is primarily attributable to the launch of our Phase 3 ATLAS study for UGN-102 at the end of 2020, and development cost of UGN-301, partially offset by a decrease in R&D expense related to Jelmyto.

SG&A Expense: Selling, general and administrative expenses for the third quarter ended September 30, 2021 were $21.6 million, including non-cash share-based compensation expense of $4.5 million. This compares to $22.1 million, including non-cash share-based compensation expense of $5.2 million, for the same period in 2020. The $0.5 million decrease is primarily attributable to higher launch related commercial spend in 2020.

Financing on Prepaid Forward Obligation: UroGen reported financing expense related to the prepaid forward obligation to RTW Investments of $6.8 million for the third quarter ended September 30, 2021.

Net Loss: UroGen reported a net loss of $30.2 million, or basic and diluted net loss per ordinary share of $1.35, for the third quarter ended September 30, 2021. This compares to $28.8 million, or basic and diluted net loss per ordinary share of $1.31, for the same period in 2020.

Cash & Cash Equivalents: As of September 30, 2021, cash, cash equivalents and marketable securities totaled $110.3 million.

2021 Operating Expense and Revenue Guidance: The Company is reducing its anticipated full year 2021 operating expenses to the range of $137 million to $142 million, from $155 million to $165 million, the new guidance includes non-cash share-based compensation expense of $22 to $25 million, subject to market conditions. In addition, the Company is providing full year 2021 revenue guidance of $47 million to $51 million.

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 non-muscle invasive bladder cancer. Utilizing the RTGel^TM 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 ATLAS Trial

ATLAS was a global, open-label, randomized controlled Phase 3 trial designed to assess the efficacy and safety of UGN-102, with or without transurethral resection of bladder tumor (TURBT), versus TURBT alone in patients diagnosed with low-grade intermediate risk non-muscle invasive bladder cancer (LG-IR-NMIBC), defined as 1 or 2 of the following: new or recurrent multifocal bladder tumors, a solitary new or recurrent tumor >3 cm, or LG-IR-NMIBC recurrence in less than 12 months following a prior tumor diagnosis requiring endoscopic surgical resection or ablation.

Patients were randomized 1:1 to either UGN-102 or TURBT. Patients in the UGN-102 arm were treated with six weekly intravesical instillations of UGN-102. At the 3-month time point, patients were assessed for response. Patients who have demonstrated a complete response to either UGN-102 or TURBT, will continue for long-term follow-up for evidence of recurrence. Patients who demonstrate presence of persistent disease at 3-months, in either arm, will undergo a TURBT and then will also continue for long-term follow up for evidence of recurrence. The primary endpoint of the study was disease free survival. On November 10, 2021, the Company announced that, following discussions with the U.S. Food & Drug Administration, it has ceased enrollment in the ATLAS study and plans to initiate a new, single-arm Phase 3 study of UGN-102 in early 2022. All patients enrolled in the treatment arm of ATLAS will continue to receive treatment and undergo follow up.
