Overview
11 DESCRIPTION Eptinezumab-jjmr is a humanized immunoglobulin G1 (IgG1) monoclonal antibody specific for calcitonin gene-related peptide (CGRP) ligand. Eptinezumab-jjmr has an approximate molecular weight of 143 kD. Eptinezumab-jjmr is produced in Pichia pastoris yeast cells by recombinant DNA technology.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Eptinezumab-jjmr is a humanized monoclonal antibody that binds to calcitonin gene-related peptide (CGRP) ligand and blocks its binding to the receptor. 12.2 Pharmacodynamics The relationship between the pharmacodynamic activity and the mechanism(s) by which eptinezumab-jjmr exerts its clinical effects is unknown. 12.3 Pharmacokinetics Eptinezumab-jjmr exhibits linear pharmacokinetics and exposure increases proportionally with doses from 100 mg to 300 mg after intravenous administration. Steady-state plasma concentration is attained after the first dose with a once every 3-month dosing schedule. Distribution The central volume of distribution (Vc) for eptinezumab-jjmr is approximately 3.7 liters.
