In ATTAIN-2, orforglipron met the primary and all key secondary endpoints, with compelling efficacy results and a safety profile consistent with injectable GLP-1 medicines

Participants with obesity or overweight and type 2 diabetes, a population with increased difficulties losing weight, lost an average of 22.9 lbs (10.5%) on the highest dose, with A1C reduced by an average of 1.8%
