Maridebart cafraglutide vs Semaglutide

GLP-1 agonism paired with GIP receptor antagonism — the opposite GIP direction to tirzepatide. A long-acting GLP-1 receptor agonist engineered for once-weekly dosing. Side by side: type, evidence tier, receptor, molecular weight, and half-life — the same fields as each monograph, rearranged so the engineering difference is visible.

Common questions

What is the difference between Maridebart cafraglutide and Semaglutide?
Maridebart cafraglutide is an engineered analog based on Glucagon-like peptide-1; Semaglutide is an engineered analog based on Glucagon-like peptide-1. Maridebart cafraglutide signals at GLP-1 receptor (agonist) + GIP receptor (antagonist); Semaglutide signals at GLP-1 receptor (GLP-1R).
How do the half-lives of MariTide and Semaglutide compare?
The reported circulating half-life of Maridebart cafraglutide is ~21 days (monthly dosing); Semaglutide is ~7 days (~165 h). These are reference values for the native or representative form — educational only, not dosing advice.
