EMGALITY® (galcanezumab-gnlm): Metabolism and Elimination
Emgality (galcanezumab) is expected to be degraded via catabolic pathways in the same manner as endogenous IgG.
Additional Information Regarding Metabolism and Elimination
Galcanezumab is an IgG4 monoclonal antibody and is expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG.1,2
As such, it is not expected to
inhibit metabolic or induce enzymatic pathways
be metabolized by the cytochrome P450 families of drug-metabolizing enzymes, and
The CL/F was 0.008 L/h and the elimination half-life of galcanezumab was approximately 27 days.1,2
