IRVINE, CA, USA & BASEL, Switzerland I Urovant Sciences (Nasdaq: UROV), a clinical-stage biopharmaceutical company developing and commercializing innovative therapies for urologic conditions, today announced that it has initiated COURAGE, an international Phase 3 trial to evaluate the safety and efficacy of vibegron for symptoms of overactive bladder (OAB) in men who are receiving pharmacological treatment for benign prostatic hyperplasia (BPH). Vibegron is an investigational beta-3 agonist that has previously been evaluated in Phase 2b and Phase 3 studies in patients with overactive bladder.

“There are limited clinical data available in men who are taking medications for symptoms associated with benign prostatic hyperplasia, yet continue to experience overactive bladder symptoms,” said Dr. Cornelia Haag-Molkenteller, Chief Medical Officer of Urovant.

An estimated 4.5 million men in the United States are being treated for BPH1, however half of them also have OAB symptoms.2 Medications used to treat BPH do not address OAB symptoms. Anticholinergics, a class of medication prescribed for OAB symptoms, are not indicated for OAB symptoms in men receiving pharmacological treatment for BPH and carry risks, including urinary retention, for these patients.3

“COURAGE is an important development program for vibegron as there is currently no FDA-approved treatment specifically indicated for men with OAB who are already on a BPH medication,” Dr. Haag-Molkenteller continued. “Based on our discussions with the FDA, we believe that this study could serve as the basis for a New Drug Application submission for vibegron in this indication.”

About the COURAGE Phase 3 Trial

The COURAGE study is a randomized, double blind, placebo-controlled trial in men with BPH who are also taking BPH medications but continue experiencing OAB symptoms. The study will be conducted in two phases, with the first phase focusing on safety and the second phase assessing efficacy and safety. Approximately 1,000 patients who meet eligibility requirements will be randomized to receive either 75 mg of vibegron or placebo daily for 24 weeks.

The co-primary efficacy endpoints will be measured at 12 weeks and include:

  • Change from baseline in the average number of micturitions per 24 hours
  • Change from baseline in the average number of urgency episodes per 24 hours

Secondary endpoints include change from baseline in the average number of nocturia episodes per night, which is awakening at night to use the bathroom to urinate.

The duration for the double-blind study is 24 weeks. In addition, a 28-week open-label extension study will evaluate the long-term safety and efficacy of vibegron in men with OAB symptoms and on another therapy for BPH. Adverse events will be monitored throughout the trial. The 75 mg dose is the same dose tested in the international EMPOWUR Phase 3 trial for vibegron in patients with OAB. The Company recently announced positive topline results from the pivotal Phase 3 EMPOWUR study.
