NORTH CHICAGO, Ill., May 17, 2017 /PRNewswire/ -- AbbVie (NYSE: ABBV), a global biopharmaceutical company, in cooperation with Neurocrine Biosciences, Inc. (NASDAQ: NBIX), today announced that data from two replicate Phase 3 studies evaluating the efficacy and safety of elagolix, an investigational, orally administered gonadotropin-releasing hormone (GnRH) antagonist, in premenopausal women with endometriosis, will be presented at the 13th World Congress on Endometriosis in Vancouver, Canada.  New data highlighting the effects of two different elagolix doses and dosing regimens on ovarian sex hormones and ovulation will also be presented.

"Endometriosis is associated with painful symptoms that can be debilitating and there have been few recent medical advancements for women suffering from this disease," said Rob Scott, M.D., Vice President, Development and Chief Medical Officer, AbbVie.

About Endometriosis
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.^1,2 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.^1,3 There is no cure for endometriosis,⁴ 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.⁵ In more extensive cases, surgical interventions (e.g., laparotomy or laparoscopy) are often pursued, and may not be curative for all individuals.⁵

About Elagolix
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 rapid, reversible, dose-dependent inhibition of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion, leading to reduced ovarian production of the sex hormones, estradiol and progesterone, while on therapy. Elagolix is currently being investigated in diseases that are mediated by sex hormones, such as uterine fibroids and endometriosis. To date, elagolix has been studied in over 40 clinical trials totaling more than 3,000 subjects. AbbVie plans to submit a New Drug Application to the U.S. Food and Drug Administration (FDA) for endometriosis in 2017. Phase 3 trials of elagolix for the management of uterine fibroids are ongoing.
