drugs for overactive bladder (OAB)

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.   Read more.

Kyorin Receives Approval from Japan’s Ministry of Health, Labour and Welfare for Vibegron for Overactive Bladder

Urovant Sciences, a clinical-stage biopharmaceutical company focused on developing novel therapies for urologic conditions, today announced that Kyorin Pharmaceutical Co., Ltd. (Kyorin) received marketing approval from Japan’s Ministry of Health, Labour and Welfare for vibegron for the treatment of adults with overactive bladder (OAB) in Japan.  Kyorin licensed vibegron for Japan from Merck & Co., Inc. in 2014, and later expanded the license to include certain other Asian countries in 2017. Urovant licensed rights to vibegron for the United States and the rest of the world from Merck, Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc. in 2017 and subsequently entered into a collaboration agreement with Kyorin later that year. Under the collaboration agreement, Urovant and Kyorin share information related to the development of vibegron, including clinical trial and nonclinical study data. 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.
