Clinical Study of a Conventional and Flexible Extended Oral Contraceptive of EE/DRSP With or Without Metafolin in Latin America

July 14, 2014 updated by: Bayer

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

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.
