 IRVINE, Calif. & BASEL, Switzerland--(BUSINESS WIRE)--Sep. 24, 2019--

 Urovant Sciences (Nasdaq: UROV), a clinical-stage biopharmaceutical company focused on developing novel therapies for urologic conditions, today announced positive data from the ongoing double-blind extension of the Phase 3 trial of its investigational drug candidate vibegron, a next-generation, once-daily oral beta-three adrenergic agonist in development for the treatment of overactive bladder.

As previously reported, once-daily vibegron met both co-primary endpoints in the 12-week Phase 3 EMPOWUR study, achieving statistical significance over placebo on both reduction in daily urge urinary incontinence (UUI) episodes (p<0.0001) and reduction in daily micturitions (p<0.001).

Highlights from the double-blind extension of the Phase 3 EMPOWUR study include:

 
     
  • Vibegron further improved treatment benefit on key OAB symptoms (micturitions, UUI, urgency, and total incontinence) over the 40-week extension period
  •  
  • 61% of patients on vibegron achieved at least a 75% reduction in their daily urge urinary incontinence episodes from baseline at week 52
  •  
  • 41% of patients on vibegron became “dry,” defined as having no urge urinary incontinence episodes at week 52
  •  
  • Vibegron demonstrated a favorable long-term safety and tolerability profile consistent with previous clinical experience
  •  
 

“The double-blind extension of the EMPOWUR study provides further compelling data that vibegron has the potential to provide long-term benefits for people suffering with overactive bladder,” said Dr. Cornelia Haag-Molkenteller, Chief Medical Officer at Urovant. “These data increase our confidence in the vibegron OAB development program and we believe vibegron has the potential, if approved by the FDA, to become an exciting next-generation treatment option for patients suffering from OAB.”

More details from the extension study will be presented at future medical meetings. Urovant intends to file a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) by early 2020.

 About EMPOWUR 

EMPOWUR was an international randomized, double-blind placebo- and active comparator controlled clinical trial evaluating the safety and efficacy of investigational vibegron in men and women with symptoms of overactive bladder, including frequent urination, sudden urge to urinate, and urge incontinence or leakage. A total of 1,518 patients were randomized across 215 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, 506 patients who completed the EMPOWUR trial were enrolled in a 40-week double-blind extension study to evaluate the safety of longer-term treatment up to 52 weeks. The co-primary endpoints of the EMPOWUR study were: change from baseline in the average number of micturitions per 24 hours; and change from baseline in the average number of urge urinary incontinence (UUI) episodes per 24 hours in patients who have an average of one or more UUI episodes per day prior to treatment. Secondary endpoints included changes in the frequency of urinary urgency episodes and incontinence episodes, and self-reported quality of life scores.
