Urovant Sciences® Presents New Data from EMPOWUR Study, Advancing Knowledge of the Treatment of Overactive Bladder at the 2022 American Urological Association Meeting

  • New analyses of data from the Phase 3 EMPOWUR Extension Study of GEMTESA® (vibegron) 75 mg provided additional insight into the long-term effects of the product. These data were featured in podium presentations PD38-11 and PD38-12:
    • In a subgroup analysis of adults, 65 years old or above with overactive bladder, treatment with GEMTESA was safe and well tolerated. Treatment with GEMTESA was associated with sustained reductions from baseline in average daily micturition, urge urinary incontinence (UUI) episodes and urgency episodes. These results were consistent with the overall EMPOWUR study population (PD38-11).
    • GEMTESA at 52 weeks was associated with sustained and patient-perceived meaningful improvements in both the OAB questionnaire (OAB-q) and Patient Global Impression (PGI) scores in the EMPOWUR extension trial (PD38-12).

IRVINE, Calif. & BASEL, Switzerland--(BUSINESS WIRE)-- Urovant Sciences, a wholly owned subsidiary of Sumitovant Biopharma Ltd., announced new analyses from the Phase 3 EMPOWUR Extension Study of GEMTESA, presented Sunday at the 2022 annual meeting of the American Urological Association (AUA2022). The meeting is being held in New Orleans from May 13-16, 2022.

“The additional analyses of data on our overactive bladder therapy, GEMTESA, further confirm this drug’s potential utility and durability in this patient population,” said Sef Kurstjens, MD, PhD, Executive Vice President and Chief Medical Officer of Urovant Sciences. “This is an additional demonstration of Urovant’s commitment to providing effective therapies for patients with urologic conditions.”

Two podium presentations at AUA2022 on May 15 featured new analyses of data from the EMPOWUR 40-week extension trial of GEMTESA (vibegron) 75 mg. This was a Phase 3, randomized, double-blind, active-comparator controlled, parallel-group multicenter study to evaluate long-term safety and efficacy in patients with symptoms of OAB. GEMTESA is approved by the U.S. Food and Drug Administration for the treatment of OAB symptoms of UUI, urgency, and urinary frequency in adults.

The first podium presentation, PD38-11, presented at 8:40-8:50 a.m. by Jeffrey Frankel, MD, Medical Director, Seattle Urology Research Center, Seattle, Washington, is titled, “Long-Term Efficacy and Safety of Vibegron for Overactive Bladder in Patients ≥65 Years Old: Analysis from the EMPOWUR Extension Trial.” In a subgroup analysis of adults, 65 years old or above with overactive bladder, treatment with GEMTESA was safe and well tolerated. Treatment with GEMTESA was associated with sustained reductions from baseline in average daily micturition, UUI episodes, and urgency episodes. These results were consistent with the overall EMPOWUR Extension Study population.

The second podium presentation, PD38-12, presented at 8:50-9:00 a.m. by David Staskin, MD, Associate Professor of Urology, Tufts University School of Medicine, is titled, “Long-Term Patient-Reported Outcomes of Vibegron for Overactive Bladder: Analyses from the EMPOWUR Extension Trial.” This analysis of data from the EMPOWUR Extension Trial supports that patient-perceived meaningful improvements in OAB questionnaire (OAB-q) and Patient Global Impression (PGI) scores were consistent with GEMTESA’s improvements in OAB symptoms and a favorable safety and tolerability profile during the 52-week treatment period.

About the EMPOWUR Trial

The EMPOWUR trial was an international, randomized, double-blind, placebo, and active comparator-controlled Phase 3 clinical trial evaluating the safety and efficacy of investigational vibegron in men and women with symptoms of overactive bladder, including frequent micturition, urgency, and UUI. 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.

About the 40-Week EMPOWUR Extension

The EMPOWUR 40-week extension trial was a Phase 3, randomized, double-blind, active-comparator controlled multicenter study to evaluate the long-term safety and efficacy of vibegron in patients with symptoms of overactive bladder. The extension study enrolled approximately 500 EMPOWUR completers. The primary endpoint was safety, measured by incidence of adverse events. Secondary endpoints were changes from EMPOWUR baseline at week 52 in average daily micturitions, UUI, urgency, and total urinary incontinence.

About Overactive Bladder

Overactive bladder (OAB) is a clinical condition that occurs when the bladder muscle contracts involuntarily. Symptoms may include urinary urgency (the sudden urge to urinate that is difficult to control), urgency incontinence (unintentional loss of urine immediately after an urgent need to urinate), frequent urination (usually eight or more times in 24 hours), and nocturia (waking up more than two times in the night to urinate).1

Approximately 30 million Americans suffer from bothersome symptoms of OAB, which can have a significant impairment on a patient’s day-to-day activities.1, 2


GEMTESA is a prescription medicine for adults used to treat the following symptoms due to a condition called overactive bladder:

  • urge urinary incontinence: a strong need to urinate with leaking or wetting accidents
  • urgency: the need to urinate right away
  • frequency: urinating often

It is not known if GEMTESA is safe and effective in children.


Do not take GEMTESA if you are allergic to vibegron or any of the ingredients in GEMTESA.

Before you take GEMTESA, tell your doctor about all your medical conditions, including if you have liver problems; have kidney problems; have trouble emptying your bladder or you have a weak urine stream; take medicines that contain digoxin; are pregnant or plan to become pregnant (it is not known if GEMTESA will harm your unborn baby; talk to your doctor if you are pregnant or plan to become pregnant); are breastfeeding or plan to breastfeed (it is not known if GEMTESA passes into your breast milk; talk to your doctor about the best way to feed your baby if you take GEMTESA).

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

What are the possible side effects of GEMTESA?

GEMTESA may cause serious side effects including the inability to empty your bladder (urinary retention). GEMTESA may increase your chances of not being able to empty your bladder, especially if you have bladder outlet obstruction or take other medicines for treatment of overactive bladder. Tell your doctor right away if you are unable to empty your bladder.

The most common side effects of GEMTESA include headache, urinary tract infection, nasal congestion, sore throat or runny nose, diarrhea, nausea, and upper respiratory tract infection. These are not all the possible side effects of GEMTESA. For more information, ask your doctor or pharmacist.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
