Additional Information Regarding Galcanezumab Drug Interactions

Pharmacokinetic Characteristics

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

  • produce any active metabolites.2-4

Drug Interactions Studies Were Not Conducted

Galcanezumab is not metabolized by cytochrome P450 enzymes; therefore, interactions with concomitant medications that are substrates, inducers, or inhibitors of cytochrome P450 enzymes are unlikely.1 Therefore, no drug interaction studies were conducted.3

There are no known interactions for galcanezumab, drug-drug or otherwise.3
