§ 1

Mechanism of action

  • Mazdutide is a dual agonist at GLP-1 and glucagon receptors, derived from oxyntomodulin (OXM).
  • The GLP-1 action governs insulin secretion and appetite, while the glucagon action is intended to address energy expenditure and hepatic fat metabolism.
  • It is being developed mainly in Asia (Innovent/Eli Lilly) for obesity and type 2 diabetes.
§ 2

Research status

  • Mazdutide is in advanced clinical development, focused on Chinese study populations.
  • A Phase III study published in 2025 (GLORY-1) in Chinese adults with obesity or overweight documented significant weight reductions versus placebo.
  • Further Phase II/III studies are investigating efficacy and safety in obesity without diabetes.
  • There is no approval outside China to date.
