Three-year-old Areteia Therapeutics Inc. hit the primary endpoint in its Exhale-4 phase III study of dexpramipexole for eosinophilic asthma, bringing the oral small molecule one step closer to the U.S. market, where it could challenge currently approved injectable anti-IL-5/5R biologics.

Areteia Therapeutics Inc. has launched to put its lead candidate, dexpramipexole, an oral treatment for eosinophilic asthma, through a phase III trial. Areteia was created by Knopp Biosciences LLC, which has put the small-molecule eosinophil maturation inhibitor through a phase II study, and also by Population Health Partners. Areteia has both the development and commercial rights to dexpramipexole.

Biohaven Pharmaceutical Holding Co. Ltd. signed a deal that could be worth more than $1 billion to take over Channel Biosciences LLC, a subsidiary of Knopp Biosciences LLC, and its Kv7 channel targeting platform. A key part of the deal is BHV-7000, formerly known as KB-3061, described as a potent activator of Kv7.2 and Kv7.3, key subunits involved in neuronal signaling and in regulating the hyperexcitable state in epilepsy. The compound is expected to enter clinical investigation this year, with focal epilepsy as the lead indication.
