Summary

This study tested a new medicine called survodutide for weight loss in 274 Japanese adults with obesity and related health problems like diabetes or high blood pressure. Participants received weekly injections of survodutide or a placebo for about 1.5 years, along with diet and exercise advice. The main goals were to see how much weight they lost and if at least 5% of body weight was reduced.
