Design outcomes

Primary

MeasureTime frame
Main Objective: To explore the pharmacodynamic (PD) effects, and specifically on occurrence and timing of ovulation with pregnancy risk, of ellaOne taken after pills of combined oral contraception (COC) were missed for three consecutive days during the first week of COC use and were resumed either on the day of ellaOne intake or five days later.;Secondary Objective: To explore in the 5 days after ellaOne intake the PD effects on ovarian activity (particularly ovulation risk) of ellaOne taken after 3 consecutive COC pills missed in 1st week of use then resumed on ellaOne intake day or 5 days later To show ovarian activity (particularly occurrence and timing of ovulations) in baseline period (BAS); assess similarity level with experimental period (EXP) where women missed 3 COC pills, took ellaOne, resumed COC on ellaOne intake day or 5 days later To evaluate ovarian quiescence (OQ) duration &proportion of women with OQ over the 28-day BAS To evaluate OQ duration and proportion of women with OQ over the 28-day EXP where women missed 3 COC pills, took ellaOne, resumed COC on ellaOne intake day or 5 days later; with specific attention to 5 days after ellaOne intake To evaluate safety (specifically effects on spotting and vaginal bleeding) of ellaOne taken after 3 COC pills missed in 1st week of use then resumed on ellaOne intake day or 5 days later;Primary end point(s): a. Ovarian Activity Score (quiescence, ovarian activity, ovulation at risk of pregnancy) b.Occurrence of ovulation with risk of pregnancy c.Time to ovulation with risk of pregnancy ;Timepoint(s) of evaluation of this end point: Follicular diameter and levels of hormones in serum will be measured throughout baseline, experimental and post-experimental periods Ovulation at risk of pregnancy will be defined as: a. A postovulatory image is observed on transvaginal ultrasound. It is defined as follow: Image observed after abrupt disappearance of FLS OR Image observed after reduction in size of the leading fol

Secondary

MeasureTime frame
Secondary end point(s): Safety of treatment intake;Timepoint(s) of evaluation of this end point: Analysis of spotting / vaginal bleeding under treatment and occurrence of adverse events. Vital signs and laboratory safety parameters will also be described by quantitative statistics, at each time point
