Myomectomy vs Uterine Artery Embolization vs GnRh Antagonist for AUB-L

This is a prospective cohort study comparing the novel FDA-approved oral GnRH antagonist ORIAHNN (elagolix, estradiol, and norethindrone acetate capsules; elagolix capsules) to uterine artery embolization (UAE) or myomectomy (abdominal, laparoscopic, or hysteroscopic) for treatment of heavy menstrual bleeding due to leiomyomas. Uterine leiomyomas, also called fibroids, are hormone-dependent growths in the uterine muscle that are common in reproductive-age women (1). Leiomyomas can often lead to heavy menstrual bleeding. Definitive treatment for abnormal uterine bleeding due to leiomyomas is hysterectomy, but for patients who desire uterine conservation, a variety of treatment options exist. Regulation of menses with combined oral contraceptives or progestin only oral formulations are generally considered first line treatment but are not curative or effective for many patients. Another treatment option is a myomectomy, which is the surgical resection or removal of myomas. Myomectomy can be performed via hysteroscopy or laparoscopy, or by a vaginal or an abdominal approach. The route of removal depends on myoma location and patient symptoms. Another treatment option is Uterine fibroid or uterine artery embolization (UFE/UAE). UAE is a minimally invasive procedure where permanent particles are delivered to and block/embolize the blood supply to the myoma via a fluoroscopy directed arterial catheter. This typically leads to a decrease in fibroid size and associated bleeding (2). ORIAHNN, an oral GnRH antagonist that was FDA-approved in 2020, has demonstrated significant decrease in myoma-associated heavy menstrual bleeding compared to placebo (1) but has not been compared to other standard of care interventions. The primary objective of this study is to compare this novel medication to the common AUB-L treatments UAE and Myomectomy.
