Brief Summary
A randomized study evaluating the continued safety and efficacy of elagolix in the management of moderate to severe endometriosis-associated pain in pre-menopausal women.
Brief Title
Study to Evaluate the Long-Term Safety and Efficacy of Elagolix in Adults With Moderate to Severe Endometriosis-Associated Pain
Detailed Description
This is a Phase 3 multicenter, double blind randomized study to assess the continued safety and efficacy of the 150 mg once daily (QD) and 200 mg twice daily (BID) doses of elagolix in premenopausal women with moderate to severe endometriosis-associated pain who completed the 6 month treatment period in the pivotal study M12-665 (NCT01620528). The study consists of 2 periods: a 6 month Treatment Period and a post treatment follow-up period of up to 12 months.
Participants who received elagolix in the pivotal study who met all entry criteria continued to receive the same dose, either elagolix 150 mg QD or elagolix 200 mg BID for up to an additional 6 months in this extension study; participants who received placebo in the pivotal study were randomized in a 1:1 ratio to receive either elagolix 150 mg QD or elagolix 200 mg BID for up to 6 months.
An electronic diary will be used to collect endometriosis-associated pain, uterine bleeding, and analgesic medication use for endometriosis associated pain on a daily basis.
All participants who prematurely discontinued treatment (unless pregnant or elected surgery for endometriosis) or completed the 6-month Treatment Period in this extension study were to enter the Post-treatment Follow-up (PTFU) Period within this study for up to 12 months.

Extension Study to Evaluate the Long-Term Safety and Efficacy of Elagolix in Subjects With Moderate to Severe Endometriosis-Associated Pain
Primary Outcomes
Outcome Description
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.

Outcome Description
Permitted rescue analgesics varied by country and were limited to non-steroidal anti-inflammatory drugs (NSAID) (naproxen 500 mg), or opioid analgesics (hydrocodone 5 mg + acetaminophen 300 mg or 325 mg, and/or codeine 30 mg + acetaminophen 300 mg). Use of rescue analgesic medications taken for endometriosis-associated pain was recorded by the participant daily in the e-Diary as the total number of pills/tablets of each type taken within a 24-hour period. Any rescue analgesic use (NSAID and/or opioid) was calculated as the total number of pills divided by the number of days in the window (i.e. average daily pill count) over the 35-day window prior to and including the reference study day.

Outcome Description
The EHP-30 is an instrument to measure health-related quality of life in women with endometriosis. The EHP-30 consists of two parts: a core questionnaire containing 5 scales that are applicable to all women with endometriosis and includes pain, control and powerlessness, emotional well-being, social support, and self-image, and a modular part containing 6 scales which do not necessarily apply to all women with endometriosis.
Each question in the core questionnaire is scored on the following scale: 0 = Never, 1 = Rarely, 2 = Sometimes, 3 = Often, 4 = Always.
The pain dimension consists of 11 questions. The dimension score ranges from 0 to 100, where 0 = best possible health status as measured by the questionnaire; 100 = worst possible health status. A negative change from baseline score indicates improvement in quality of life.
