All Clinical Trials for Estradiol And Norethindrone Acetate

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00000897 ↗	A Study to Evaluate the Effects of Different Methods of Birth Control on the Drug Actions of Zidovudine (an Anti-HIV Drug) in HIV-Positive Women and to Compare Zidovudine Metabolism in Men and Women	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	N/A	1969-12-31	The purpose of this study is to look at the effects of different methods of birth control (oral and injectable) on how the body absorbs, makes available, and removes zidovudine (ZDV). This study will also evaluate the differences in men and women in how the body absorbs, makes available, and removes ZDV. Past research has shown that the effectiveness of ZDV as an anti-HIV drug might be decreased in individuals who use certain methods of birth control. ZDV may also have different effects in men compared to women.
NCT00229996 ↗	Medical Treatment of Endometriosis-Associated Pelvic Pain	Completed	Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)	Phase 3	2004-07-01	The Specific Aim of this project is to compare the efficacy and cost-effectiveness of continuous oral contraceptives versus leuprolide/norethindrone in the treatment of endometriosis-associated chronic pelvic pain. This comparison will be based on a randomized, double-blind, trial of women with chronic pelvic pain who have been diagnosed with endometriosis at the time of surgery within the last 3 years. We hypothesize that, over a 12-month period of postoperative treatment, the efficacy of oral contraceptives is no worse than leuprolide/norethindrone, and that treatment with oral contraceptives is more cost-effective.
NCT00338052 ↗	Study of Bleeding With Extended Administration of an Oral Contraceptive	Completed	Warner Chilcott	Phase 2	2006-06-01	This is an non-comparative study. There is no statistical hypothesis. The effects of extension of treatment on bleeding will be recorded and described.
NCT00350480 ↗	Treatment of Non-Gestational Acute Uterine Bleeding: A Randomized Trial	Completed	Kaiser Permanente	N/A	2003-04-01	To determine the relative efficacy of multidose medroxyprogesterone acetate (MPA, Provera) and a multidose, monophasic combination oral contraceptive in the treatment of hemodynamically stable women with non-gestational, acute uterine bleeding.
NCT00391807 ↗	Study of Safety and Efficacy of an Oral Contraceptive	Completed	Warner Chilcott	Phase 3	2006-11-01	This is a non-comparative study. The primary objective of the study is to assess the efficacy of a low dose oral contraceptive in the prevention of pregnancy. The secondary objectives are to assess the incidence of intracyclic bleeding; and to assess the safety and tolerability of the product.
NCT00458458 ↗	Treatment of Endometriosis With Norethindrone Acetate ( NA) VS. Gonadotropin- Releasing Hormone (GnRH) Agonist (Lupron Depot 11.25 mg)	Unknown status	National Institutes of Health (NIH)	Phase 3	2004-08-01	(A) Major 1) to compare the effectiveness of norethindrone acetate (NA) with GnRH agonist (Lupron-Depot-3) in relieving symptoms of endometriosis, 2) to compare bone density in the two treated groups in order to demonstrate that NA does not affect bone density; (B) Minor: 1) To compare the lipid profiles of patients in the two groups to confirm the hypothesis that the effects of NA and GnRH agonists on lipid profiles are similar, 2) To determine whether quality of life, assessed by questionnaire, is better in patients assigned to NA than in patients assigned to GnRH, 3) To determine whether NA has fewer adverse effects than GnRH agonist.

Estradiol and Norethindrone Acetate: Clinical Trials, Market Analysis, and Projections

Introduction

Estradiol and Norethindrone Acetate is a combination hormone replacement therapy (HRT) widely used to manage menopausal and post-menopausal symptoms. This article provides an update on the current clinical trials, market analysis, and future projections for this drug.

Clinical Trials Update

Ongoing and Recent Trials

Several clinical trials are currently underway or have recently been completed to evaluate the efficacy and safety of Estradiol and Norethindrone Acetate in various therapeutic areas.

• Relugolix/Estradiol/Norethindrone Acetate Combination: Trials such as those for Myfembree (Relugolix/Estradiol/Norethindrone Acetate) have shown promising results. These trials, which include Phase 3 studies, have evaluated the combination for treating conditions like uterine fibroids and have demonstrated no significant safety concerns[3][5].
• Endometriosis Treatment: Clinical trials are also exploring the use of Estradiol/Norethindrone Acetate in combination with other therapies for the treatment of endometriosis. For example, a trial sponsored by Boston Children's Hospital is investigating the use of an IUD and Norethindrone Acetate for this condition[1].
• Menopausal Symptoms: Various studies have focused on the efficacy of Estradiol/Norethindrone Acetate in managing menopausal symptoms. These trials often compare different formulations and delivery methods, such as oral, transdermal, and vaginal routes, to optimize treatment outcomes[4].

Key Findings

• Safety and Efficacy: Recent trials have shown that Estradiol/Norethindrone Acetate combinations can effectively manage menopausal symptoms without significant adverse effects. For instance, a study on women with polycystic ovarian syndrome (PCOS) and gingivitis found that the combination did not have detrimental effects on gingiva and could reduce systemic and gingival inflammation[1].
• Mechanism of Action: The drug acts through multiple mechanisms, including agonism of estrogen receptors (ERs) and progesterone receptors (PRs), and antagonism of gonadotropin-releasing hormone receptors (GnRHRs). This multifaceted action helps in managing a range of symptoms and conditions associated with hormonal imbalances[3][5].
