- More than 1,500 patients enrolled in international Phase 3 clinical trial EMPOWUR, exceeding recruitment target
- Top-line efficacy and safety data from Phase 3 trial expected by the end of March 2019
BASEL, Switzerland & IRVINE, Calif.–(BUSINESS WIRE)–Nov. 8, 2018– Urovant Sciences (Nasdaq: UROV), a clinical-stage biopharmaceutical company focused on developing novel therapies for urologic conditions, today announced it completed enrollment in its international Phase 3 clinical trial, EMPOWUR, evaluating the safety and efficacy of vibegron as a treatment for adults with symptoms of overactive bladder. Vibegron is an investigational oral beta-3 adrenergic agonist.
“I am proud of the progress made since initiating our robust EMPOWUR clinical trial in March of 2018,” said Dr. Cornelia Haag-Molkenteller, Chief Medical Officer of Urovant. “Exceeding our enrollment ahead of schedule underscores the interest in this trial and reinforces the need for this significantly underserved patient population.”
EMPOWUR is a randomized, double-blind placebo- and active comparator controlled clinical trial in men and women with symptoms of overactive bladder, including frequent urination, sudden urge to urinate, and urge incontinence or leakage. Top-line efficacy and safety data are anticipated by the end of March 2019.
A total of 1,530 patients who met the enrollment criteria were randomized across 216 study sites into one of three groups for a 12-week treatment period with a four-week safety follow up period: vibegron 75 mg administered orally once daily; placebo administered orally once daily; or tolterodine ER 4 mg administered orally once daily. Additionally, the first 507 patients who completed the EMPOWUR trial have been enrolled in a 40-week double-blind extension study to evaluate the safety of longer-term treatment.
The co-primary endpoints of the EMPOWUR study are:
- Change from baseline in the average number of micturitions per 24 hours in all patients
- Change from baseline in the average number of urge urinary incontinence (UUI) episodes per 24 hours in patients who have one or more UUI episodes per day prior to treatment
Vibegron, which has been widely studied and recently received regulatory approval in Japan, is investigational in the United States and has not been approved by the U.S. Food and Drug Administration. Vibegron has previously been evaluated in multiple clinical trials with more than 2,600 OAB patients, including a completed international randomized, double-blind, placebo-controlled Phase 2b study with more than 1,300 subjects.
In 2017, Urovant licensed global rights, excluding Japan and certain Asian territories, for the development and commercialization of vibegron. Urovant initiated EMPOWUR, its international Phase 3 clinical trial for vibegron, in March 2018.
About Overactive Bladder
Overactive bladder is a clinical condition characterized by the sudden urge to urinate that is difficult to control (urgency), with or without accidental urinary leakage (urge urinary incontinence), and usually with increased frequency of urination. The exact cause is unknown, making this a difficult condition to treat. In the United States, more than 30 million people over the age of 40 suffer from the bothersome symptoms of OAB1, which can lead to depression, anxiety and a negative impact on quality of life.2
