Mechanism of action

What Mazdutid does in the body — step by step.

01

Mazdutide is a dual agonist at GLP-1 and glucagon receptors, derived from oxyntomodulin (OXM).

02

The GLP-1 action governs insulin secretion and appetite, while the glucagon action is intended to address energy expenditure and hepatic fat metabolism.

03

It is being developed mainly in Asia (Innovent/Eli Lilly) for obesity and type 2 diabetes.

Research status

How far along is the evidence?

PRECLINICALEARLY CLINICAL STUDIESCLINICALLY ESTABLISHED
Mazdutide is in advanced clinical development, focused on Chinese study populations.
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.
