The dash for MASH is gaining momentum, with Roche AG acquiring 89bio Inc. and its phase III FGF21 analogue, pegozafermin, for treating metabolic dysfunction-associated steatohepatitis, in a deal worth up to $3.5 billion.

“People have some inability to focus on [Regeneron Pharmaceuticals Inc.’s] pipeline,” which stands as “the most prolific in the industry, I would dare to say,” CEO Leonard Schleifer remarked during the Morgan Stanley health care conference Sept. 8. Most recently, Regeneron bragged on two prospects. The ultra-rare disease fibrodysplasia ossificans progressiva (FOP) took center stage Sept. 17 with news that the phase III Optima trial testing fully human monoclonal antibody garetosmab met its primary endpoint. Separately, Regeneron provided updated analyses of the phase II Courage trial that tested new pairings of GLP-1 receptor agonist semaglutide plus the anti-GDF8/anti-myostatin compound trevogrumab, with or without garetosmab, in obesity.

Artificial intelligence is no longer just a supporting tool in biotechnology – it is beginning to define the way drugs are discovered, tested and advanced into the clinic, speakers said during the Bio Hong Kong conference Sept. 10 to 13.

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.

Activity in some clinical parameters is leading Atyr Pharma Inc. to plan a sit-down with regulators, even though the tRNA synthetase-derived drug efzofitimod missed its primary endpoint of steroid tapering in the phase III Efzo-Fit study against the interstitial lung disease pulmonary sarcoidosis (PS). CEO Sanjay Shukla said his firm maintains “a high degree of conviction” regarding the candidate. “But I want to make sure we have the best briefing book possible” before consulting with the U.S. FDA, which will happen as soon as possible.

As Avidity Biosciences Inc. brought the second-largest follow-on offering of the year to the market, the company also released positive early and midstage stage results of del-zota, an antibody-oligonucleotide conjugate, in treating Duchenne muscular dystrophy.
