Cagrilintide vs Semaglutide

A long-acting amylin analog built for once-weekly dosing and GLP-1 pairing. 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 Cagrilintide and Semaglutide?
Cagrilintide is an engineered analog based on Amylin; Semaglutide is an engineered analog based on Glucagon-like peptide-1. Cagrilintide signals at Amylin receptors (calcitonin receptor + RAMP); Semaglutide signals at GLP-1 receptor (GLP-1R).
How do the half-lives of Cagrilintide and Semaglutide compare?
The reported circulating half-life of Cagrilintide is ~7 days (159-195 h); Semaglutide is ~7 days (~165 h). These are reference values for the native or representative form — educational only, not dosing advice.
