Brief Summary

The primary purpose of this trial is to assess the pharmacokinetic profile of NOMAC, E2 and E1 after multiple and single dose administration of the combined oral contraceptive NOMAC-E2

Detailed Description

This trial was designed to assess the pharmacokinetic profile of NOMAC, E2 and E1 after multiple dose (MD) and single dose (SD) administration of NOMAC-E2 in healthy female volunteers.

In total 25 subjects were to enter the trial. These subjects were synchronized for menstrual cycle by taking 1 tablet NOMAC-E2 (2.5 mg / 1.5 mg) daily for a minimum of 2 weeks. This was followed by a 7-day pill-free interval. After this, all subjects were to be exposed to the open-label MD treatment with 1 tablet NOMAC-E2 (2.5 mg / 1.5 mg) once daily, during 24 days. This was followed by a second pill-free interval of 10 days, to allow for sufficient washout of NOMAC-E2. On treatment day 35, 20 subjects were to receive 1 tablet NOMAC-E2 (2.5 mg / 1.5 mg) and 5 subjects were to receive a placebo tablet in a double blinded setup. After treatment day 35 and before follow-up, all subjects would again have a pill-free interval of 7 days. After follow-up, all subjects could return to their own contraceptive schedule. Follow-up took place on treatment day 42.

Bleeding pattern and tablet intake were assessed by means of a subject diary to be completed on a daily basis. Blood sampling for pharmacokinetic and pharmacodynamic purposes were collected at several time points before, during and after the MD and SD period. In order to explore any possible influence of NOMAC-E2 on the QT/QTc interval, a small placebo group was designed within the SD period, to allow for comparison with the active-treated group. In addition several safety assessments (vital signs, ECGs, trans vaginal ultrasound evaluation, physical, gynecological and breast examinations, cervical smear, routine laboratory parameters and adverse events) were performed.
