Endometriosis Study

Endometriosis Study

Endometriosis is a painful uterine condition that affects 6-10% of women of reproductive age. Endometriosis has an impact on everyday life, social interactions, sexuality and sexual activity, as well as mental health. This research will see how effectively elagolix works in the body when used with combined oral contraceptives (COC) and/or how safe it is compared to a placebo (does not contain treatment drug). Participants with endometriosis and related pain will be evaluated for their response to dysmenorrhea (painful periods).

The primary objective is to evaluate the efficacy of elagolix when added to a COC regimen in women with endometriosis and related dysmenorrhea, in reducing pain associated with menstruation, which is measured by:

  1. The mean number of days with moderate or severe menstrual cramps (primary endpoint).
  2. The number of days with vaginal bleeding.

Secondary objectives are to compare the effects of elagolix therapy when it is added to a COC regimen and used alone, and to establish an effect size for dysmenorrhea at the end of the treatment period (to estimate clinical meaningfulness).

  • Evaluating Whether the Study medication (approved), when taken together with an approved birth control pill to reduce moderate to severe endometriosis pain.
  • Study last up to 18-month Period.
  • Premenopausal females (18 to 49) years of age.
  • Have had surgical confirmation of endometriosis and associated moderate to severe pain.
  • Subjects must not be pregnant or breastfeeding.
  • Subjects must not have a surgical history of hysterectomy or bilateral oophorectomy.
  • Patient reimbursement for participation.
