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[1][2].
