AbbVie NDA for Endometriosis Pain Drug Approved
FDA has approved an AbbVie NDA for Orilissa (elagolix), the first oral gonadotropin-releasing hormone (GnRH) antagonist specifically developed for women with moderate to severe endometriosis pain. Approval is supported by data from two replicate Phase 3 studies involving nearly 1,700 women with moderate to severe endometriosis pain. Clinical trial data demonstrated Orilissa significantly reduced the three most common types of endometriosis pain — daily menstrual pelvic pain, non-menstrual pelvic pain and pain with sex, according to the company. “A higher proportion of women treated with Orilissa 150 mg once daily and 200 mg twice daily were responders for daily menstrual pain and non-menstrual pelvic pain compared to placebo in a dose-dependent manner at month three,” Abbvie says. Women were defined as responders if they experienced a reduction in daily menstrual pain and non-menstrual pelvic pain with no increase in analgesic use.
AbbVie says the recommended duration of use for Orilissa is up to 24 months for the 150 mg once daily dose and up to six months for the 200 mg twice daily dose because it causes a dose-dependent decrease in bone mineral density (BMD). BMD loss is greater with increasing duration of use and may not be completely reversible after stopping treatment, it says.
