UroGen Pharma Ltd. (Nasdaq: URGN), a biopharmaceutical company dedicated to building and commercializing novel solutions that treat specialty cancers and urologic diseases, today announced financial results for the first quarter ended March 31, 2021 and provided an overview of the Company’s recent developments.

“We are pleased with the progress we have made across our expanded pipeline and the momentum we’ve seen since we reported fourth quarter 2020 earnings in March. The number of patient enrollments, patient starts and doses shipped in April were each up more than 100% compared to January. We believe this signifies broader awareness of Jelmyto and increasing physician support,” said Liz Barrett, President and Chief Executive Officer of UroGen. “As we look to the remainder of 2021, with increased vaccination rates and eased COVID-19 restrictions across the United States, we feel confident that this momentum will continue as we advance our mission to bring novel solutions to patients with specialty cancers and urologic diseases.”

Business Highlights and Upcoming Milestones:

Jelmyto (mitomycin) for pyelocalyceal solution:

• UroGen achieved net product revenue of $7.5 million for the first quarter of 2021.
• As of May 1, 2021, 316 sites have been activated, which means they have completed their internal processes and have treated or are ready to treat patients. This represents a 26% increase since March 1, 2021.
• Sites that have treated more than one patient as of May 1, 2021 increased to 40, compared to 31 as of March 1, 2021: an increase of approximately 30%.

UGN-102 (mitomycin) for intravesical solution:

• ATLAS, the Phase 3 trial of UGN-102, continues to enroll patients with low-grade intermediate risk non-muscle invasive bladder cancer (LG-IR-NMIBC). The ATLAS trial is expected to enroll approximately 630 patients and is evaluating UGN-102 as a primary non-surgical treatment compared to standard of care – transurethral resection of bladder tumor (TURBT) – in patients diagnosed with LG-IR-NMIBC.

Platform expansion:

About Jelmyto^®

Jelmyto (mitomycin) for pyelocalyceal solution, is a drug formulation of mitomycin indicated for the treatment of adult patients with low-grade upper tract urothelial cancer (LG-UTUC). Utilizing the RTGel™ technology platform, UroGen’s proprietary sustained release, hydrogel-based formulation, Jelmyto is designed to enable longer exposure of urinary tract tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. Jelmyto is delivered to patients using standard ureteral catheters or nephrostomy tube. The U.S. FDA previously granted Orphan Drug, Fast Track, and Breakthrough Therapy Designations to Jelmyto for the treatment of LG-UTUC. On April 15, 2020, the FDA approved Jelmyto, making it the first drug approved for the treatment of LG-UTUC in adult patients.

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.

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 reported topline interim results from the Phase 2b OPTIMA II trial in May 2020 and initiated a Phase 3 study to further investigate UGN-102 in the treatment of this condition in December 2020.

About the Phase 3 ATLAS Trial

ATLAS is 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. The trial is anticipated to enroll approximately 630 patients in over 100 clinical sites in the U.S., Europe and Israel.

Patients will be randomized 1:1 to either UGN-102 or TURBT. Patients in the UGN-102 arm will be treated with six weekly intravesical instillations of UGN-102. At the 3-month time point, patients will be 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 is disease free survival.
