NCT00474851 ↗	The Effect of Hormonal Add-Back Therapy in Adolescents Treated With a GnRH Agonist for Endometriosis: A Randomized Trial	Completed	Boston Children’s Hospital	Phase 2	2007-08-01	The purpose of this study is to determine whether a regimen of norethindrone acetate + placebo or norethindrone acetate + conjugated estrogens is superior in maintaining skeletal health and quality of life in adolescents treated with a GnRH agonist for endometriosis.
NCT01391052 ↗	Pretreatment With Norethindrone Acetate Prior to Levonorgestrel IUS Insertion for Heavy Menstrual Bleeding	Unknown status	Scott and White Hospital & Clinic	Phase 4	2011-01-01	Problematic uterine bleeding after the insertion of the LNG IUS is a well documented side effect. The levonorgestrel intrauterine system (LNG IUS) was approved for treatment of heavy menstrual bleeding (HMB) by the FDA in October 2009. To reduce the incidence and severity of post-insertional uterine bleeding, pretreatment with norethindrone acetate may effectively slough the endometrium prior to insertion of the LNG IUS.
NCT02353247 ↗	Use of Norethindrone Acetate for Management of Bleeding Associated With the Etonogestrel Contraceptive Implant	Unknown status	Norton Healthcare	N/A	2015-08-01	The overall objective of this study is to confirm that oral progesterone is an effective way to manage bothersome bleeding; thus increasing the rate of continuation of the etonogestrel contraceptive implant in adolescents.
NCT02542410 ↗	Dopamine Receptor Agonist Therapy for Pain Relief in Women Suffering From Endometriosis: A Pilot Study	Completed	Boston Children's Hospital	Phase 2	2016-05-01	The proposed pilot study will estimate the efficacy and safety of a novel therapeutic agent, cabergoline, with a clinical standard therapy, norethindrone acetate, for the treatment of endometriosis-associated pain in young women with endometriosis.
