What potential drug-drug interactions does Emgality®▼ (galcanezumab) have?

Detailed information

Pharmacokinetic Characteristics

As a humanised IgG4 monoclonal antibody, galcanezumab is expected to be degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG.¹

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

No drug interaction studies were conducted. No pharmacokinetic drug interactions are expected based on the characteristics of galcanezumab.¹

There are no known interactions for galcanezumab, drug-drug or otherwise.²
