Eli Lilly and CompanyStructure Therapeutics' trial data for its obesity drugs failed to impress, reinforcing the competitive strength of Eli Lilly's established oral weight loss therapies.
Structure Therapeutics shares fell on Tuesday after trial data for its lead obesity candidates, ACCG-2671 and aleniglipron, failed to lift investor expectations amid competition from established drugs by Novo Nordisk and Eli Lilly. In a Phase 1/2a single ascending dose trial, ACCG-2671, a dual amylin and calcitonin receptor agonist, caused about a 3% average weight reduction after a single dose in healthy volunteers without obesity, with a half-life of about six days supporting a potential once-weekly oral regimen. The company has started the multiple ascending dose portion of the trial, with topline data expected in the first half of 2027. For aleniglipron, data from the ACCESS open-label extension trial showed that patients on the 180 mg dose lost up to 16% of their weight after 72 weeks with no plateau, while enrollment continues in the ACCOMPLISH-1 and ACCOMPLISH-2 Phase 3 studies, with topline data expected in the second half of 2028. In comparison, FDA-approved oral weight loss therapies from Novo Nordisk and Eli Lilly have achieved average weight loss of up to 14% and 11% over 64 and 72 weeks, respectively.
