Study Endpoints

Primary Endpoints

Area Under the Plasma Concentration-time Curve From Time Zero Extrapolated to Infinity (AUC0-inf) of Ethinyl Estradiol and Norethisterone
Pre-dose, 0.3, 0.6, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48, 60 and 72 hours post-dose on Days 1, 2, 3, 4, 15, 16, 17 and 18

AUC0-inf was calculated by combining AUC0-t and AUCextra. AUCextra represents an extrapolated value obtained by Clast pred/Lambda z, where Clast pred was the calculated serum concentration at the last sampling time point at which the measured serum concentration is at or above the Lower Limit of quantification (LLOQ) and Lambda z was the apparent terminal rate constant determined by log-linear regression analysis of the measured serum concentrations of the terminal log-linear phase.

Maximum Observed Plasma Concentration (Cmax) of Ethinyl Estradiol and Norethisterone
Pre-dose, 0.3, 0.6, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36, 48, 60 and 72 hours post-dose on Days 1, 2, 3, 4, 15, 16, 17 and 18

Cmax was obtained directly from the concentration versus time curve.
