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 participants.

Conditions

Endometriosis

Keywords

Gonadotropin-Releasing Hormone Antagonist; Endometriosis associated pain; Dysmenorrhea (DYS); Non-Menstrual Pelvic Pain (NMPP); Elagolix

Outcome Measures

Primary Outcomes (2)

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

  The DYS pain scale ranges from 0 (none) to 3 (severe). The criteria for a responder was based on a pre-defined threshold and accounted for analgesic use.

  At Month 3 of the Treatment Period

• Percentage of Responders at Month 3 Based on Daily Assessment of Non-Menstrual Pelvic Pain (NMPP)

  The NMPP pain scale ranges from 0 (none) to 3 (severe). The criteria for a responder was based on a pre-defined threshold and accounted for analgesic use.

  At Month 3 of Treatment Period

Secondary Outcomes (109)

• Change From Baseline to Month 3 in Numeric Rating Scale (NRS) Scores

  Baseline, Month 3 of the Treatment Period

• Change From Baseline to Month 6 in DYS

  Baseline, Month 6 of Treatment Period

• Change From Baseline to Month 6 in NMPP

  Baseline, Month 6 of Treatment Period

• Change From Baseline to Month 3 in Analgesic Use Across Both Classes of Rescue Analgesics

  Baseline, Month 3 of Treatment Period

Eligibility Criteria

• Age: 18 Years - 49 Years
• Sex: female
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Premenopausal female, between 18 and 49 years of age, inclusive, at the time of signing consent.
• Clinical diagnosis of endometriosis (laparoscopy or laparotomy) performed within 10 years of entry into Washout (if applicable) or Screening.
• Agrees to use required birth control methods during the entire length of participation in the study.
• Subject has a Composite Pelvic Signs and Symptoms Score total score of ≥ 6 at Screening with a score of at least 2 for dysmenorrhea AND at least 2 for non-menstrual pelvic pain. 5. Subjects must have at least two menstrual cycles 24 to 38 days within the Screening Period, prior to Day 1

You may not qualify if:

• Subject is pregnant or breast feeding or is planning a pregnancy within the next 24 months or is less than 6 months postpartum, post-abortion, or post-pregnancy at the time of entry into the Screening Period.
• Subject has chronic pelvic pain that is not caused by endometriosis that requires chronic analgesic or other chronic therapy, or that would interfere with the assessment of endometriosis related pain.
• Clinically significant gynecologic condition identified on Screening transvaginal ultrasound or endometrial biopsy.
• Subject has a history of osteoporosis or other metabolic bone disease.
• Subject has a current history of undiagnosed abnormal genital bleeding.
