The objective of this three-arm study is to evaluate the effect of a flexible extended regimen of an EE+DRSP containing OC on bleeding pattern and to investigate the compliance with daily pill intake when the investigational product is provided in a blister package or a compliance aiding dispenser with a pill reminder function. The third treatment arm will be a reference comparator arm of a standard 24+4 regimen of the identical hormone combination.

Condition Intervention Phase
Contraception Drug: EE20/DRSP (BAY86-5300) Drug: EE20/DRSP/L-5-MTHF (BAY98-7071) Drug: EE20/DRSP/L-5-MTHF (BAY98-7071) + L-5-MTHF (BAY86-7660) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Multicenter, Open-label, 3-arm, Active-controlled, Parallel-group, 1-year Study to Investigate the Efficacy and Safety of a Flexible Regimen of the Combined Oral Contraceptive, With and Without 0.451 mg Levomefolate Calcium (BAY98-7071 and BAY86-5300, Respectively) Versus the Standard 24 + 4 Regimen With Levomefolate (BAY98-7071 + BAY86-7660) and to Assess Compliance With a Device (CADDY) in Healthy Women Who Desire Contraception
