Abbvie presents new investigational data for elagolix at the 2018 american college of obstetricians endometrial biopsy side effects

We strive to improve care for women living with endometriosis and uterine fibroids, said Dawn Carlson, M.D., M.P.H., vice president, general medicine development. These presentations highlight safety and efficacy data for elagolix and demonstrate AbbVie’s commitment in the field of women’s health.

Primary and secondary efficacy and safety data from two extension Phase 3 studies evaluating the use of elagolix in women with endometriosis with associated moderate to severe pain will be showcased. In addition, new data highlighting rescue analgesic use, fatigue scores and pain burden from pivotal Phase 3 studies of elagolix in women with endometriosis and new data from a Phase 2b study highlighting the impact of elagolix on productivity in women with uterine fibroids will also be presented.


Elagolix is not approved by regulatory authorities and its safety and efficacy have not been established.

Endometriosis is a chronic and painful disease that affects an estimated 1 in 10 women of reproductive age. 1 Endometriosis occurs when tissue similar to that normally found in the uterus begins to grow outside of the uterus, leading to long-term pelvic pain (during or between periods), pain with intercourse and other painful symptoms. 1 These growths are called lesions and can occur on the ovaries, the fallopian tubes, or other areas near the uterus, such as the bowel or bladder. 1, 2 Estrogen fuels the growth of lesions. 2 There is no cure for endometriosis, 3 and the associated pain is currently managed with oral contraceptives, progestins, danazol, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and GnRH agonists, many of which are not specifically indicated for the treatment of endometriosis. 1,4 In more extensive cases, surgical interventions (e.g., laparotomy or laparoscopy) are often pursued, and may not be curative for all individuals. 4

Uterine fibroids (also called leiomyomas or myomas) are non-cancerous, hormonally-responsive muscle tissue tumors of the uterus. 5 Fibroids are the most common benign tumors in women and can affect up to 80 percent of women by age 50. 6,7 African American women are more likely to experience fibroids and do so at a younger age. 7 Fibroids can range in size, shape, number and location. 5 Fibroids can cause symptoms that affect daily life in approximately 25% of women. 7 Symptoms may include heavy menstrual bleeding, painful periods, vaginal bleeding at times other than menstruation, anemia, pain in the abdomen or lower back, pain during sex, difficulty urinating or frequent urination, constipation, rectal pain or difficulty getting pregnant. 5 Treatment options for uterine fibroids include surgery (hysterectomy, myomectomy), hysteroscopy, endometrial ablation, uterine artery embolization, magnetic resonance imaging-guided ultrasound and medical management with treatments such as oral contraceptives, progestins, selective progesterone receptor modulators, and gonadotropin-releasing hormone (GnRH) agonists, some of which are not specifically indicated for the treatment of uterine fibroids. 5

Elagolix, a gonadotropin-releasing hormone (GnRH) receptor antagonist, is an orally administered, short-acting molecule that blocks endogenous GnRH signaling by binding competitively to GnRH receptors in the pituitary gland. Administration results in readily reversible, dose-dependent inhibition of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion, leading to reduced ovarian production of the ovarian sex hormones, estradiol and progesterone, while on therapy. Elagolix is currently being investigated in diseases that are mediated by ovarian sex hormones, such as uterine fibroids and endometriosis. To date, elagolix has been studied in over 40 clinical trials totaling more than 3,700 subjects. In Q4 2017, the FDA granted priority review for AbbVie’s NDA for endometriosis. The Prescription Drug User Fee Act (PDUFA) date for the FDA to complete its review is in Q3 2018.Phase 3 trials of elagolix for the management of uterine fibroids are ongoing.
