Popis: Background Erenumab is a human anti-calcitonin gene-related peptide monoclonal antibody developed for migraine prevention. Migraine predominately affects women of childbearing age; thus, it is important to determine potential drug–drug interactions between a common oral contraceptive and drugs used to treat migraine. Objectives We sought to evaluate potential drug–drug interactions between erenumab and a common oral contraceptive. Methods Healthy women received three cycles of a norgestimate/ethinyl estradiol-containing oral contraceptive with a single 140-mg subcutaneous dose of erenumab during cycle three. Norgestimate metabolites (norgestrel and norelgestromin) and ethinyl estradiol pharmacokinetics were evaluated in the absence and presence of erenumab. Primary endpoint was peak plasma concentration (Cmax) and area under concentration-time curve from time 0 to 24 h (AUCtau). Luteinizing hormone, follicle-stimulating hormone, and progesterone concentrations were evaluated as pharmacodynamic markers. Results Erenumab did not influence the pharmacokinetics of norelgestromin, norgestrel, or ethinyl estradiol. Least-squares mean estimates (90% confidence interval) for Cmax ratios were 1.05 (0.90–1.23), 1.06 (0.97–1.16), and 1.04 (0.88–1.22) for norelgestromin, norgestrel, and ethinyl estradiol, respectively. Respective AUCtau ratios were 1.02 (0.94–1.12), 1.03 (0.96–1.10), and 1.02 (0.91–1.14). Luteinizing hormone, follicle-stimulating hormone, and progesterone concentrations were similar after exposure to oral contraceptive alone and with erenumab. Conclusion Erenumab did not alter the pharmacokinetics of the active components of an estrogen/progestin combination oral contraceptive. Thus, no change in contraceptive efficacy is expected with erenumab. Trial Registration ClinicalTrials.gov NCT02792517.
