PRIMARY outcome

Timeframe: Cycle 2, day 21 and cycle 3, day 21 at predose and 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, and 24 hours post oral contraceptive dose.

Population: The pharmacokinetic (PK) analysis set included all participants for whom at least 1 EE, NGMN, and NG PK parameter or endpoint could be adequately estimated. Data are reported for participants with observations at each time point.

The pharmacokinetics of ethinyl estradiol (EE) were characterized during cycle 2 following the last active dose of oral contraceptive in the cycle (cycle day 21) without erenumab, and during cycle 3 following the last active dose of oral contraceptive in the cycle (cycle day 21), 11 days after a single dose of erenumab.
