Sponsor:	Duramed Research
Information provided by:	Duramed Research
ClinicalTrials.gov Identifier:	NCT00117273

Purpose

This is a randomized, open-label study to evaluate pituitary ovarian suppression in healthy, reproductive-aged women using three different regimens of oral contraceptives (OCs). Two extended regimen OCs, Seasonale (levonorgestrel/ethinyl estradiol 0.15/0.03 mg for 84 days followed by 7 days of placebo), and Seasonique (levonorgestrel/ethinyl estradiol 0.15/0.03 mg for 84 days followed by 7 days of ethinyl estradiol 0.01 mg), and a 28-day regimen OC, Portia (levonorgestrel/ethinyl estradiol 0.15/0.03 mg for 21 days followed by 7 days of placebo).

Further study details as provided by Duramed Research:

Primary Outcome Measures:

Compare differences in hormone patterns (follicle stimulating hormone [FSH], luteinizing hormone [LH], inhibin-B, and estradiol) [ Time Frame: Before, during and after the 7-day hormone free interval or EE-supplemented interval ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Compare the differences in hormone withdrawal symptoms [ Time Frame: Before, during and after the 7-day hormone free interval or EE-supplemented interval ] [ Designated as safety issue: No ]
Compare differences in ovarian follicular development [ Time Frame: Before, during and after the 7-day hormone free interval or EE-supplemented intervals ] [ Designated as safety issue: No ]
