Brief summary
The proposed study will provide an assessment of the effect of this combination on endocrine function, metabolic control and hemostasis during 6 treatment cycles. This will be compared to the effects of two reference COCs.
Interventions
15 mg E4 combined with 3 mg DRSP administered in a 24/4-day regimen (i.e. 24 days of pink active tablets followed by 4 days of white placebo tablets). One tablet per day orally for 6 treatment cycles.
DRUG30 mcg EE/150 mcg LNG
30 mcg EE combined with 150 mcg LNG administered in a 21/7-day regimen (i.e. 21 days of yellow active tablets followed by 7 days of white placebo tablets). One tablet per day orally for 6 treatment cycles.
20 mcg EE combined with 3 mg DRSP administered in a 24/4-day regimen (i.e. 24 days of pink active tablets followed by 4 days of white placebo tablets). One tablet per day orally for 6 treatment cycles.
