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).
NCT00128934 ↗ Study Evaluating Combination of Levonorgestrel (LNG) and Ethinyl Estradiol (EE) in Premenstrual Dysphoric Disorder Completed Wyeth is now a wholly owned subsidiary of Pfizer Phase 3 2005-08-01 The purpose of this study is to determine whether levonorgestrel (LNG)/ethinyl estradiol (EE) is effective in treating the symptoms of severe premenstrual syndrome (PMS).
NCT00161681 ↗ Study Evaluating Levonorgestrel/Ethinyl Estradiol (LNG/EE) in PMS Completed Wyeth is now a wholly owned subsidiary of Pfizer Phase 3 2005-07-01 The purpose of this study is to determine whether LNG/EE is effective in the treatment of menstrual cycle related symptoms.
NCT00195559 ↗ Study Evaluating Combination of Levonorgestrel and Ethinyl Estradiol in Pre-Menstrual Dysphoric Disorder Completed Wyeth is now a wholly owned subsidiary of Pfizer Phase 3 2005-09-01 The purpose of this study is to determine whether Levonorgestrel/Ethinyl Estradiol (LNG/EE) is effective in treating the symptoms of severe Premenstrual Dysphoric Disorder.
NCT00204451 ↗ Human Ovarian Follicular Dynamics and Emergency Contraception Completed Canadian Institutes of Health Research (CIHR) Phase 4 2005-07-01 The researchers hypothesize that emergency contraception (EC) will initiate the changes associated with atresia or ovulatory failure at all stages of follicular development and that the image attributes associated with atresia will be similar regardless of the diameter of the dominant follicle when ovarian suppression is initiated. Second, changes associated with atresia may be observed, but ovulation of the dominant follicle is unimpeded.
NCT00204451 ↗ Human Ovarian Follicular Dynamics and Emergency Contraception Completed University of Saskatchewan Phase 4 2005-07-01 The researchers hypothesize that emergency contraception (EC) will initiate the changes associated with atresia or ovulatory failure at all stages of follicular development and that the image attributes associated with atresia will be similar regardless of the diameter of the dominant follicle when ovarian suppression is initiated. Second, changes associated with atresia may be observed, but ovulation of the dominant follicle is unimpeded.
NCT00213096 ↗ Effects of Hormonal Contraceptives on Liver Proteins and Coagulation Factors: A Comparison of a Contraceptive Vaginal Ring and an Oral Contraceptive Completed United States Agency for International Development (USAID) Phase 2 2003-03-01 The purpose of this 3-month (cycle) study was to evaluate the effects of hormonal contraceptives containing a progestin and an estrogen on liver proteins and coagulation factors that are sensitive to estrogen. In this study, a contraceptive vaginal ring containing Nestorone┬« (a progestin with no androgenic properties) and ethinyl estradiol was compared to an oral contraceptive containing levonorgestrel (an androgenic progestin) and ethinyl estradiol.
