NEW YORK, May 9, 2019 - UroGen Pharma Ltd. (Nasdaq:URGN), a clinical-stage biopharmaceutical company developing treatments to address unmet needs in uro-oncology, today announced financial results for the first quarter ended March 31, 2019 and provided an overview of the Company’s recent developments.

“The accomplishments and performance of UroGen during the first quarter have set the stage for a pivotal and exciting year ahead as we prepare for the potential approval and commercialization ofUGN-101, our first investigational candidate. Our top priority remains completion of our rolling New Drug Application (NDA) forUGN-101 for the treatment of patients withlow-grade upper tract urothelial cancer (LG UTUC) and, with our commercial preparations well underway, we are confident in our readiness to deliver on a strong launch in the first half of 2020,” said Liz Barrett, President and Chief Executive Officer of UroGen. “Our company sees great possibilities for the RTGel platform within uro-oncology, especially around new therapeutic modalities. Our goal is to leverage that and continue to build a company with sustainable growth via a robust pipeline as well as assessing opportunities via external partnerships.”

Recent Highlights

• UGN-101 Clinical Development:

• At the 114^th American Urological Association (AUA) Annual Meeting in Chicago, Seth Lerner, M.D. delivered a presentation during the plenary session that highlighted the unmet need and potential forUGN-101 to change the treatment paradigm for patients with LG UTUC.

• The updated analysis demonstrated that in the OLYMPUSintent-to-treat population, 71 patients had undergone primary disease evaluation (PDE) at the time of the analysis and 42 of the 71 patients (59 percent) achieved a complete response (CR).Forty-one patients enteredfollow-up. At the time of the analysis, 27 patients underwent asix-month evaluation, and 24 out of 27 patients (89 percent) have remained disease free at six months. The most common adverse events observed were urinary tract infection, ureteral narrowing and stricture formation. The majority of ureteral events were reported as mild to moderate and have resolved. Full Phase 3 data from the OLYMPUS trial is anticipated for 2H 2019.

• The Company remains on track to complete its rolling NDA forUGN-101 in 2H 2019 and is planning for approval in 1H 2020. If approved,UGN-101 would be the first drug approved for thenon-surgical treatment of LG UTUC. Full data is planned for 2H 2019.

• Pipeline Advancement:

• UGN-102:

• The Company continues to enroll patients in its Phase 2b OPTIMA II clinical trial ofUGN-102 (mitomycin gel) for intravesical instillation as a first-line chemoablation agent in the treatment of patients with intermediate risklow-gradenon-muscle invasive bladder cancer (LG NMIBC), a form of disease associated with a high risk of recurrence.

• Initial data from the OPTIMA II trial ofUGN-102 is expected in 2H 2019.

• There are currently no drugs approved by the FDA as first-line treatment for LG NMIBC.UGN-102 represents a substantial opportunity in UroGen’s pipeline and has the potential to be a treatment option for up to approximately 80,000 patients for whom repetitive surgical resection via Transurethral Resection of Bladder Tumor (TURBT) remains the standard of care.

• UGN-201:

• UroGen is currently evaluating the optimal pathway to advanceUGN-201, a TLR7/8 immunomodulatory agent for the treatment of high-grade bladder disease.

• Commercial Preparations:

• The Company continues to accelerate itspre-commercial activities and infrastructurebuild-out to support the anticipated U.S. approval and launch ofUGN-101 targeted for 1H 2020. The focus is on building awareness of our RTGel technology and unmet needs in UTUC to support rapid adoption and seamless integration ofUGN-101 into the urologist practice following regulatory approval.

• A strong team of seven medical science liaisons (MSLs) have been strategically deployed across the U.S. to engage in scientific exchange and clinical support.

• The Company launched www.UTUC.com, the first resource designed to address a void in the urology space by educating patients about UTUC and available treatment options.

• Business Development:

• UroGen recently entered into an agreement with Janssen Research & Development, LLC (Janssen) to conduct an early-stage feasibility evaluation in a therapeutic area of mutual interest. UroGen and Janssen will each conduct certain activities under the terms of the agreement.
