First Big Test Approaches for Urovant

Investors who backed Urovant’s $140m flotation last September will soon find out whether the money was well spent. Before the end of March the company will release topline pivotal data on the overactive bladder project vibegron, a β3-adrenergic receptor agonist licensed from Merck & Co, and a positive result should allow regulatory filings to follow. It seems likely that the trial will hit: Merck successfully conducted a large phase IIb study of vibegron a few years ago, and a similar compound is already on the market in the shape of Myrbetriq, which has been sold by Astellas since 2011. This well-established product has only four years of US patent life left, so if Urovant has any chance of building vibegron into a similarly large product it needs to prove that its contender is both safer and more effective.

FDA Approves Myrbetriq Combo Treatment for Overactive Bladder

The Food and Drug Administration (FDA) has approved Myrbetriq (mirabegron extended-release tablets; Astellas) in combination with the muscarinic antagonist solifenacin succinate for the treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency, and urinary frequency. In clinical trials, the combination of Myrbetriq + solifenacin succinate was associated with greater improvements in the number of incontinence episodes per 24 hours (primary endpoint), the number of micturitions per 24 hours (primary endpoint), and the volume voided per micturition (secondary endpoint) compared to placebo or to individual active components. Long-term data also demonstrated that the effects of combination treatment were maintained throughout a 1-year treatment period. Read more.

Urovant Starts Pursuit of Astellas’ Overactive Bladder Drug Myrbetriq with New Phase 3 Trial

A little later than expected, Roivant group company Urovant has started its confirmatory phase 3 program for overactive bladder (OAB) drug vibegron, originally licensed from Merck & Co. The pivotal trial—which was originally expected to get underway last year—will involve around 1,400 adults with symptoms of OAB such as urge urinary incontinence, urgency, and urinary frequency, according to Urovant. The drug already has positive phase 2b and phase 3 data in hand, so if the latest trial is positive Urovant should be able to move ahead with regulatory filings. If approved, it could become a direct competitor to Astellas’ Myrbetriq (mirabegron), the first beta3-adrenergic agonist to reach the market for OAB. And that could present a big commercial opportunity: Astellas reported sales of its drug rose 30% to 93.1 billion yen ($876 million) in the nine months to end-January 2018 with take-up driven by greater tolerability than the widely used antimuscarinic OAB drug class.
