General information about the trial
|
|||
Main objective of the trial |
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.
|
||
Protection of trial subjects |
Subjects had to be withdrawn from study medication under the following circumstances:
• Pregnancy (every attempt must be made to follow up subjects who become pregnant to determine the outcome of the pregnancy),
• Serious intercurrent problems requiring admission to the critical care unit or surgery,
• Subject unable to comply with study visits or requirements,
• Suspected unexpected serious adverse reaction to study medication,
• Subject withdraws informed consent,
• Liver enzymes levels above three times the upper limit of normal at D1 or D15 of the EXP period,
• Upon discretion of the investigator in the event of a protocol violation (inclusion/ exclusion criteria).

Recruitment
|
|||||||||||||||||||
Recruitment details |
The screening period was performed within a maximum of 28 days before start of Baseline period. The Baseline period was performed after all screening assessments are checked by the investigator. The Baseline period was from D1 to D28. The randomization was performed at D29 (= V2: D1: 1st day of the Experimental period) | ||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||
Screening details |
The women screened had a BMI <30.0 kg/m2, relied on a COC as their primary method of contraception for at least 2 cycles before they enter the baseline (B) period and were willing to continue with a COC for at least 1 cycle after end of experimental (EXP) period, must not be at risk of pregnancy and were willing to use condoms during the study. | ||||||||||||||||||
