Maridebart cafraglutide
Based on 1 Customer Validation
Maridebart cafraglutide (AMG 133) is a long-acting peptide-antibody conjugate that combines GLP-1 receptor agonist with glucose-dependent insulinotropic polypeptide (GIP) receptor antagonism. Maridebart cafraglutide shows antagonist activity against human, cynomolgus monkey and rat GIPR with IC50 values of 46.4 nM, 26.5 nM, 822.3 nM, respectively. Maridebart cafraglutide shows agonist activity against human, cynomolgus monkey, rat and mouse GLP-1R with EC50 values of 24.4 pM, 5.7 pM, 2.4 pM and 123 pM, respectively. Maridebart cafraglutide can be used for the study of obesity and type 2 diabetes.

Maridebart cafraglutide is an optimized GIPR/GLP-1R bispecific molecule engineered by conjugating a fully human monoclonal anti-human GIPR-Ab with two GLP-1 analogue agonist peptides using amino acid linkers[1][2].
Maridebart cafraglutide (AMG 133) functionally inhibits GIP signalling through human and cynomolgus monkey GIPR with similar potency, whereas it has more than 20-fold lower potency for inhibition of GIP signalling through rat GIPR and does not fully antagonize mouse GIPR with concentrations of up to 3 µM[1].
Maridebart cafraglutide, prolongs half-life by engaging neonatal Fc receptor (FcRn) recycling and reducing renal clearance, enabling sustained GLP-1 receptor activation with infrequent injections[2].
