Brief Summary:
The purpose of this study is to evaluate elagolix (NBI-56418) compared to placebo for its effects on endometriosis related pelvic pain and its safety.

Condition or disease Intervention/treatment Phase
Endometriosis, Pain Drug: Placebo Drug: Elagolix Phase 2

Detailed Description:

Participants were randomized (1:1) to 150 mg elagolix once daily or placebo once daily for the first 8 weeks of the study. Following 8 weeks of dosing, participants continued in the study for an additional 16 weeks in an open-label phase where all participants still enrolled in the study received 150 mg elagolix once daily.

There was no pre-specified primary efficacy end point for this study as there is no single key efficacy outcome measure in this exploratory Phase 2 study. However, the efficacy measures of primary interest included the daily assessment of dysmenorrhea, non-menstrual pelvic pain and dyspareunia on a 4-point scale (0 = none, 1 = mild, 2 = moderate, 3 = severe) using an e-Diary.

  17. Change From Baseline to the End of the Double-blind Treatment Phase in Endometriosis Health Profile-5 (EHP-5) [ Time Frame: Baseline and week 8 ]

    The EHP-5 is an instrument to measure health-related quality of life in women with endometriosis. The EHP-5 consists of two parts:

    • A core questionnaire consisting of five questions that measure the impact of endometriosis in areas of pain, control and powerlessness, emotional well-being, social support, and self-image with five response categories for each item (Never, Rarely, Sometimes, Often, Always)
    • A supplemental questionnaire consisting of six additional questions which assess the impact of endometriosis on the areas of work, relationship with children, sexual intercourse, feelings about the medical profession, treatment, and infertility with the same five response categories plus an additional response category of Not Relevant which was not scored.

    The scores associated with each possible outcome category are as follows: never (0), rarely (25), sometimes (50), often (75), and always (100). A negative change from baseline score indicates improvement in quality of life.


  18. Change From Baseline to the End of the Open-label Treatment Phase in Endometriosis Health Profile-5 (EHP-5) [ Time Frame: Baseline and week 24 ]

    The EHP-5 is an instrument to measure health-related quality of life in women with endometriosis. The EHP-5 consists of two parts:

    Uterine bleeding was reported daily by participants during the study using the e-Diary.

    The percentage of days a participant reported any bleeding was calculated as the total number of days the participant reported any bleeding ( light, moderate, or heavy) divided by the total number of days the participant had a non-missing e-Diary report of vaginal bleeding in the phase.


  20. Number of Days to First Posttreatment Menses [ Time Frame: From last day of study drug up to 6 weeks after the last dose. ]
    Defined as the number of days from the last dose of study drug until the start date of the first post-treatment menses.
