Structure Therapeutics (GPCR) said Tuesday that a single dose of its ACCG-2671 drug candidate reduced body weight by up to 3.3% in a phase 1/2a trial, while its aleniglipron candidate produced up to 16.2% weight loss at 72 weeks.
The company said the 3.3% reduction was observed at day 24 after a single 10 mg dose of ACCG-2671 in healthy participants without obesity. The oral small molecule dual amylin and calcitonin receptor agonist also had a roughly six-day half-life, Structure said, adding that it has started the multiple ascending dose portion of the trial. Topline data are expected in the first half of 2027.
Structure also reported 72-week results for aleniglipron, an oral small molecule GLP-1 receptor agonist, in the Access open-label extension trial. Participants receiving the 180 mg dose achieved up to 16.2% body weight loss with no evidence of a plateau.
The results support the ongoing phase 3 Accomplish program. The company said it expects topline data in H2 2028.
Shares of Structure Therapeutics were down more than 8% in Tuesday trading.
