Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Flexible (extended) treatment of EE20/DRSP (YAZ, BAY86-5300)

3 cycles of treatment, each cycle comprising 120 days intended treatment with one tablet daily of 20µg ethinyl estradiol as betadex clathrate (EE20) plus 3 mg drospirenone (DRSP) followed by a 4 day tablet-free interval. If 3 consecutive days of bleeding and/or spotting occurred during the 120 day treatment period, a 4 day tablet free interval was advised. The minimum period between 2 tablet free intervals was 24 days. After each 4 day tablet free interval, a new 120 day intended treatment period was to be restarted, resulting in a minimum of 3 and maximum of 13 withdrawal bleeding episodes during one year of treatment.

Group Type EXPERIMENTAL

If 3 consecutive days of bleeding and/or spotting occurred during the 120 day treatment period, a 4 day tablet free interval was advised. The minimum period between 2 tablet free intervals was 24 days.

Fixed extended treatment of EE20/DRSP (YAZ, BAY86-5300)

3 cycles of treatment, each cycle comprising 120 days uninterrupted treatment with one tablet daily of 20µg ethinyl estradiol as betadex clathrate plus 3 mg drospirenone followed by a 4 day tablet free interval, 3 withdrawal bleeding episodes during one year of treatment were expected.
