UroGen Pharma Announces First Patient Enrolled in Allergan Phase 2 Clinical Trial of RTGel™ in Combination with BOTOX® for the Treatment of Overactive Bladder

RA’ANANA, Israel and NEW YORK, Nov. 06, 2017 (GLOBE NEWSWIRE) -- UroGen Pharma Ltd. (NASDAQ:URGN), a clinical-stage biopharmaceutical company developing treatments to address unmet needs in the field of urology, today announced the enrollment of the first patient in a Phase 2 clinical trial of RTGel™ in combination with BOTOX® (onabotulinumtoxinA) for the treatment of overactive bladder. The Phase 2 trial is being conducted by Allergan Pharmaceuticals International Limited, or Allergan, a wholly owned subsidiary of Allergan plc, under the terms of a license agreement with UroGen Pharma. RTGel™ is UroGen Pharma’s proprietary sustained release, hydrogel-based formulation technology designed to enable longer exposure of the urinary tract tissue to active pharmaceutical ingredients with which it may be combined, including BOTOX®. BOTOX® injection into the bladder is approved as a pharmacologic therapy for the treatment of overactive bladder.

“The enrollment of the first patient in the Phase 2 clinical trial marks another important milestone in our collaboration with Allergan and further demonstrates Allergan’s continued commitment to this program,” said Ron Bentsur, Chief Executive Officer of UroGen Pharma. “We believe that the innovative RTGel™/BOTOX® combination has the potential to provide an additional treatment option for the many patients suffering from overactive bladder.”

In October 2016, UroGen Pharma granted an exclusive worldwide license to Allergan to research, develop, manufacture and commercialize pharmaceutical products that contain UroGen Pharma's proprietary RTGelTM and clostridial toxins, including BOTOX®. Under the terms of the license agreement, UroGen Pharma is eligible to receive additional payments from Allergan related to the achievement of certain development, regulatory and commercial milestones, in addition to royalties on potential net sales.

About the Phase 2 Clinical Trial

The trial is a multi-center, randomized, double-blind, placebo-controlled, single-treatment, two-stage, dose-finding clinical trial on patients with overactive bladder with urgency urinary incontinence who have an inadequate response to or are intolerant to pharmacologic therapy. The first stage of the trial is a placebo-controlled, dose escalation design, followed by the second stage, a randomized, placebo-controlled design. Up to 335 patients are expected to be enrolled. Patients will receive a single bladder instillation of RTGel™ in combination with BOTOX®. The primary efficacy endpoint is the improvement of overactive bladder symptoms as measured by the reduction in urinary incontinence episodes per day.

About Overactive Bladder and RTGelTM

Overactive Bladder (OAB) is a common, often disabling condition associated with considerable negative impact on quality of life. OAB results in an uncontrolled urge to urinate, frequent urination, and, in many patients, uncontrollable leakage of urine. Standard first-line pharmacologic treatment for OAB is anticholinergic pills. However, the majority of patients stop taking the pills within one year due to an inadequate response to, or intolerance of, the medication. BOTOX® injection into the bladder is approved as a therapy for OAB.

Over 30 million people in the United States alone and 200 million people worldwide suffer from this burdensome disease.

RTGel™ has thermo-sensitive properties that enable it to convert from a liquid state when cold, into a gel once it reaches body temperature. This allows increased residence time of drugs when mixed with the gel and instilled in the bladder.
