Mechanism

Activates GLP-1 receptors on pancreatic beta cells and hypothalamic neurons to boost insulin release, cut glucagon, and suppress appetite, while GIP receptor activation strengthens the incretin effect; the Fc fusion extends circulation via FcRn recycling for monthly dosing.

Safety file

GI effects (nausea, vomiting, constipation) are most common, mild to moderate and dose-dependent; no unexpected safety signals or major cardiac events reported in Phase 2.
