Priority Review for Abbvie Endometriosis Therapy
FDA has accepted for priority review an AbbVie NDA for elagolix, an investigational, orally administered gonadotropin-releasing hormone (GnRH) antagonist for managing endometriosis with associated pain. The NDA is supported by data from randomized clinical trials involving nearly 1,700 women with moderate-to-severe endometriosis-associated pain. The company expects that the user fee review action target data will be in the second quarter next year.
Elagolix works by blocking endogenous GnRH signaling by binding competitively to GnRH receptors in the pituitary gland, according to the company. “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,” the company says. It is currently being investigated in diseases that are mediated by ovarian sex hormones, such as uterine fibroids and endometriosis.
