Conditions

Endometriosis

Keywords

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

Outcome Measures

Primary Outcomes (2)

• Percentage of Participants With a Response for Dysmenorrhea at Month 6 Based on Daily Assessment

  Response was defined as a reduction of -0.81 or more from baseline in dysmenorrhea (pain during menstruation) as well as no increase in rescue analgesic use for endometriosis-associated pain (defined as a \< 15% increase in average rescue analgesic pill count and no additional analgesic). The response threshold represents a clinically meaningful response that was determined in pivotal Study M12-665. Participants recorded rescue analgesic use for endometriosis-associated pain daily and dysmenorrhea and its impact on daily activities each day of their period in an electronic diary (e-Diary). Dysmenorrhea was assessed according to the following: * 0: No discomfort * 1: Mild discomfort but I was easily able to do the things I usually do * 2: Moderate discomfort or pain that made it difficult to do some of the things I usually do * 3: Severe pain that made it difficult to do the things I usually do. Analgesic use and pain scores were averaged over the 35 days prior to each visit.

  Baseline (defined as baseline of Study M12-665 for participants who received elagolix in the pivotal study and baseline of the extension study M12-667 for participants who received placebo in the pivotal study) and Month 6

• Percentage of Participants With a Response for Non-menstrual Pelvic Pain at Month 6 Based on Daily Assessment

  Response was defined as a reduction of -0.36 or greater from baseline for non-menstrual pelvic pain as well as no increase in rescue analgesic use for endometriosis-associated pain (defined as a \< 15% increase in average pill count of rescue analgesics and no additional analgesics). The response threshold represents a clinically meaningful response that was determined in pivotal Study M12-665. Participants recorded rescue analgesic medication for endometriosis-associated pain and assessed non-menstrual pelvic pain and its impact on their daily activities each day in an e-Diary according to the following response options: * 0: No discomfort * 1: Mild discomfort but I was easily able to do the things I usually do * 2: Moderate discomfort or pain that made it difficult to do some of the things I usually do * 3: Severe pain that made it difficult to do the things I usually do. Pain scores and analgesic use were averaged over the 35 days prior to each visit.

  Baseline (defined as baseline of Study M12-665 for participants who received elagolix in the pivotal study and baseline of the extension study M12-667 for participants who received placebo in the pivotal study) and Month 6

Secondary Outcomes (16)

• Percentage of Participants With a Response for Dysmenorrhea at Each Month Based on Daily Assessment

  Baseline (defined as baseline of Study M12-665 for participants who received elagolix in the pivotal study and baseline of the extension study M12-667 for participants who received placebo in the pivotal study) and months 1, 2, 3, 4, and 5

• Percentage of Participants With a Response for Non-menstrual Pelvic Pain at Each Month Based on Daily Assessment

  Baseline (defined as baseline of Study M12-665 for participants who received elagolix in the pivotal study and baseline of the extension study M12-667 for participants who received placebo in the pivotal study) and months 1, 2, 3, 4, and 5

• Percentage of Participants With a Response for Dyspareunia at Each Month Based on Daily Assessment

  Baseline (defined as baseline of Study M12-665 for participants who received elagolix in the pivotal study and baseline of the extension study M12-667 for participants who received placebo in the pivotal study) and months 1, 2, 3, 4, 5, and 6

• Percent Change From Baseline in Dysmenorrhea Based on Daily Assessment

  Baseline (defined as baseline of Study M12-665 for participants who received elagolix in the pivotal study and baseline of the extension study M12-667 for participants who received placebo in the pivotal study) and months 1, 2, 3, 4, 5, and 6

• Percent Change From Baseline in Non-menstrual Pelvic Pain Based on Daily Assessment

  Baseline (defined as baseline of Study M12-665 for participants who received elagolix in the pivotal study and baseline of the extension study M12-667 for participants who received placebo in the pivotal study) and months 1, 2, 3, 4, 5, and 6
