Urovant Sciences Announces Publication of Phase 2b Data for Vibegron in European Urology
The study, which demonstrated once-daily vibegron was well-tolerated and improved OAB symptoms, was published online by European Urology, a peer-reviewed medical journal and official journal of the
The international, randomized double-blind, placebo-controlled Phase 2b study including an active comparator enrolled more than 1,300 patients with OAB symptoms including frequent urination, sudden urge to urinate, and urge incontinence (leakage). In the two-part trial, patients were first randomized to once-daily oral vibegron monotherapy (3 mg, 15 mg, 50 mg or 100 mg); tolterodine extended release (4 mg); or placebo for eight weeks. In part two, patients were randomized to monotherapy, combination therapy or placebo and received either vibegron (100 mg); tolterodine (4 mg); combination vibegron (100 mg) and tolterodine (4 mg); or placebo for four weeks.
In part one, patients randomized to vibegron 50 mg and 100 mg had clinically and statistically significant decreases in the daily number of micturitions, urgency urinary incontinence episodes, total incontinence episodes and urgency episodes at week 8, versus placebo. Moreover, as early as week 2, treatment with both vibegron 50 mg and vibegron 100 mg was associated with statistically significant decreases compared to placebo across all of these key overactive bladder endpoints. Vibegron was generally well-tolerated and there were no meaningful differences in incidence or severity of adverse events observed between the treatment groups and placebo. In part two of the study, the efficacy of vibegron monotherapy on the primary endpoint – reduction in micturitions – was statistically significant and similar to results observed in part one. The incidence of dry mouth was higher among patients treated with tolterodine alone or given concomitantly with vibegron, versus those treated with vibegron monotherapy.

The exact cause is unknown, making this a difficult condition to treat. In
