Summary

This Phase 3 study tests whether a weekly injection called zenagamtide helps Asian adults with overweight or obesity lose weight safely. About 400 participants will receive either the drug or a placebo for several weeks. The main goal is to see how much body weight changes, with waist size also measured.
