Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Ansuvimab-zykl is a recombinant human monoclonal antibody with antiviral activity against Zaire ebolavirus [see Microbiology (12.4) ]. 12.2 Pharmacodynamics Ansuvimab-zykl exposure-response relationship and the time course of pharmacodynamic response is unknown. 12.3 Pharmacokinetics Limited data from 18 healthy subjects 22 to 56 years of age suggests that the pharmacokinetic profile of ansuvimab-zykl is consistent with the profile of other IgG1 monoclonal antibodies. Pharmacokinetic data are not available for Zaire ebolavirus infected patients. Specific Populations The effect of age, renal impairment or hepatic impairment on the pharmacokinetics of ansuvimab-zykl is unknown. 12.
