FDA Approves Orilissa for Endometriosis Pain
Posted on August 14, 2018

The Food and Drug Administration has approved elagolix (Orilissa) for oral treatment of moderate to severe pain associated with endometriosis, announced AbbVie and Neurocrine Biosciences; this approval makes it the first such treatment in more than a decade.
Elagolix is a gonadotropin-releasing hormone (GnRH) antagonist and the first and only one developed specifically for managing this kind of pain.
The approval is based on two 6-month, randomized, double-blind, placebo-controlled phase 3 trials that compared a total of 952 adult women treated with either elagolix with 734 treated with placebo. All of the women experienced moderate to severe endometriosis pain; their ages ranged from 18 to 49 years.
