Brief summary

A randomized study evaluating the safety and efficacy of elagolix in the management of moderate to severe endometriosis-associated pain in adult premenopausal female subjects.

Detailed description

The study consists of 4 periods: 1) Washout Period (if applicable); 2) a Screening Period of up to 100 days prior to first dose; 3) a 6 month Treatment Period; and 4) a Post treatment Follow-up Period of up to 12 months (if applicable). An electronic diary will be dispensed and training provided to record endometriosis-associated pain, uterine bleeding, and analgesic medication use for endometriosis-associated pain on a daily basis. Pregnancy testing will be performed monthly throughout the study. Subjects will be required to use nonhormonal dual contraception during the study, and will be counseled on appropriate and effective forms of birth control to promote pregnancy prevention.

Percentage of Responders at Month 3 Based on Daily Assessment of Dysmenorrhea (DYS)

The DYS pain scale ranges from 0 (none) to 3 (severe) as recorded in a daily electronic diary. The criteria for defining a participant as a responder included a reduction of -0.85 or greater from Baseline in DYS pain as well as no increased rescue analgesic use for endometriosis-associated pain.

Time frame: At Month 3 of the Treatment Period

Population: The modified intent-to-treat (mITT) analysis set; all randomized participants who took at least 1 dose of randomized, double-blind study drug. Population included mITT participants who either had data during the Month 3 35-day window or who prematurely discontinued prior to or at Month 3 and met the rules for last observation carried forward.

Patient Global Impression of Change (PGIC) Questionnaire

The PGIC questionnaire is a self-reported 7-point scale rating a participant's overall impression of change from 1 = very much improved to 7 = very much worse. Participants evaluated the change in their endometriosis-associated pain since initiation of study drug.

Time frame: Months 1, 2, 3, 4, 5, 6 of Treatment Period

Population: The mITT analysis set included all randomized participants who took at least 1 dose of randomized, double-blind study drug. Last observation carried forward. Participants with an assessment at given time point.
