New weekly shot challenges semaglutide for diabetes and weight loss
NCT ID NCT06184568
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 3 study tested a new drug called IBI362 (mazdutide) against the well-known semaglutide in 349 Chinese adults with early type 2 diabetes and obesity. Participants received weekly injections for 32 weeks, with some continuing for an extra 24 weeks. The main goal was to see how many people achieved both good blood sugar control (HbA1c below 7%) and significant weight loss (at least 10%).
