| NCT00117273 ↗ | A Study to Evaluate Suppression of the Pituitary-Ovarian Axis With Three Different Oral Contraceptive Regimens | Completed | Duramed Research | Phase 3 | 2005-06-01 | 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). |
| NCT00196365 ↗ | A Study to Evaluate the Efficacy of Seasonique for the Treatment of Cyclic Pelvic Pain | Completed | Duramed Research | Phase 3 | 2005-01-01 | This study is being conducted to evaluate the effects of treatment with Seasonique an extended-regimen oral contraceptive that utilizes low dose ethinyl estradiol during the typical hormone-free interval. Patients will receive 26 weeks of treatment. The overall study duration will be approximately 9 months. Patients will be required to record menstrual pain in a daily diary. |
| NCT01170390 ↗ | Oral Contraceptives and Body Mass Index | Completed | Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) | Phase 4 | 2009-09-01 | The main hypothesis for this study is that increased Body Mass Index (BMI) alters oral contraceptive metabolism in a manner which results in decreased effectiveness in obese women. |
| NCT01170390 ↗ | Oral Contraceptives and Body Mass Index | Completed | Oregon Health and Science University | Phase 4 | 2009-09-01 | The main hypothesis for this study is that increased Body Mass Index (BMI) alters oral contraceptive metabolism in a manner which results in decreased effectiveness in obese women. |
| NCT02922127 ↗ | Compare Daily Ulipristal Acetate and Combined Oral Contraceptive Effects on Breast Epithelial Cell Proliferation | Completed | Memorial Sloan Kettering Cancer Center | Phase 1 | 2016-12-16 | Breast cancer accounts for almost a quarter of all cancers in women. In the United States (U.S.) in 2014, more than 230,000 women were diagnosed and 40,000 died of breast cancer. There is an urgent need to develop acceptable means of preventing breast cancer both for high risk and average risk women. The proposed study is a clinical trial in premenopausal women aged 18-39 to evaluate the capacity of daily Ulipristal Acetate (UPA) to reduce breast epithelial cell proliferation (increase in number of cells in the breast) and to measure its effect compared to that found with a combined estrogen-progestin oral contraceptive (COC). UPA is an anti-progestin in use as daily medication up to 12 months for the treatment of abnormally heavy bleeding at menstruation due to uterine fibroids, and is currently in trials in the U.S. to evaluate its use as a daily contraceptive. The investigators will use breast biopsies to compare breast cell proliferation, comparing biopsies at the end of 3 months treatment to biopsies taken at baseline in the 2 groups (UPA and COC). The investigators will also compare the changes in the 2 groups to each other. The comparison of the effect of UPA to that of a conventional COC is because of UPA's potential use as a daily contraceptive. Cell proliferation in the breast occurs throughout the menstrual cycle. The actions of hormones on the breast are rapid and an anti-progestin such as UPA, which will block the action of progesterone in the breast, would be predicted to quickly lower breast cell proliferation in premenopausal women. Effects of UPA on the uterus continue to be studied and are reassuring. COC use has not been found to lower breast cell proliferation and is not associated with any decrease in risk of breast cancer. The changes in breast cell proliferation will also be compared to changes seen on breast MRI. If the changes are highly correlated future studies will be able to be done without the need for breast biopsies. |
