"E4/DRSP Endocrine Function, Metabolic Control and Hemostasis Study"

A Single Center, Randomized,Open-label,Controlled, Three-arm Study to Evaluate the Effect of a New Combined Oral Contraceptive (COC) Containing 15 mg Estetrol (E4) and 3 mg Drospirenone (DRSP) and of Two Reference COCs Containing Either 30 mcg Ethinylestradiol (EE) and 150 mcg Levonorgestrel (LNG) or 20 mcg EE and 3 mg DRSP on Endocrine Function, Metabolic Control and Hemostasis During 6 Treatment Cycles

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.
