AbbVie issued the following announcement on April 10.
AbbVie (NYSE:ABBV), a global research and development-based biopharmaceutical company in cooperation with Neurocrine Biosciences, Inc. (NASDAQ: NBIX), announced notification by the U.S. Food and Drug Administration (FDA) that it requires extended time to review additional information regarding the results of liver function tests provided by AbbVie in connection with its New Drug Application (NDA) for elagolix in endometriosis-associated pain. The Prescription Drug User Fee Act (PDUFA) date has been extended three months to Q3 2018.
In Q4 2017, the FDA granted priority review for AbbVie's NDA for endometriosis. The FDA grants priority review to medicines it determines have potential to provide significant improvements in the safety and effectiveness of the treatment of a serious disease. If approved, elagolix will be the first new oral medical management treatment option for endometriosis-associated pain in more than a decade.
"Based on our review of the data, we remain confident in our New Drug Application for elagolix in the treatment of endometriosis-associated pain," said Michael Severino, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "Elagolix has the potential to be an important new treatment option for women suffering from endometriosis and we are committed to working with the FDA to bring this therapy to patients."
The NDA for elagolix is supported by data from the largest prospective randomized clinical trials conducted to date for endometriosis. The safety and efficacy of elagolix were evaluated in nearly 1,700 women with moderate-to-severe endometriosis-associated pain. Clinical trial data demonstrated elagolix was well-tolerated and significantly reduced the three types of endometriosis-associated pain – daily menstrual pelvic pain, non-menstrual pelvic pain and painful intercourse.
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 3,000 subjects.
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.2 In more extensive cases, surgical interventions (e.g., laparotomy or laparoscopy) are often pursued, and may not be curative for all individuals.4
