Study Details

Study Description

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.

Condition or Disease Intervention/Treatment Phase
Phase 3

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.

    Primary Outcome Measures

    1. Percentage of Participants With a Response for Dysmenorrhea at Month 6 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 Month 6]

      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.

    2. Percentage of Participants With a Response for Non-menstrual Pelvic Pain at Month 6 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 Month 6]

      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.

    7. Change From Baseline in Any Rescue Analgesic Use [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]

      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.

    8. Change From Baseline in NSAID Rescue Analgesic Use [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]

      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. NSAID rescue analgesic use was calculated as the total number of NSAID 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.

    9. Change From Baseline in Opioid Rescue Analgesic Use [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]

      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. Opioid rescue analgesic use was calculated as the total number of opioid 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.

    10. Percent Change From Baseline in Endometriosis-Associated Pain Score Assessed With Numeric Rating Scale (NRS) [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]

      The NRS measured endometriosis-associated pain with and without menstruation on an 11-point scale from 0 = no pain to 10 = worst pain ever. Participants were asked to assess their endometriosis pain over the past 24 hours at it's worst at approximately the same time every day in the e-Diary. Pain scores were averaged over the 35 days prior to each visit.

    11. Percentage of Participants With a PGIC Response of Much Improved or Very Much Improved [Months 1, 2, 3, 4, 5, and 6]

      The Patient Global Impression of Change (PGIC) is a questionnaire-based assessment of the change in endometriosis pain since the initiation of study drug. The participant was asked to select from one of seven response categories: Very Much Improved Much Improved Minimally Improved Not Changed Minimally Worse Much Worse Very Much Worse

    12. Change From Baseline in Endometriosis Health Profile-30 (EHP-30) Pain Dimension [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, 3, and 6]

      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.

    13. Change From Baseline in Endometriosis Health Profile-30 (EHP-30) Sexual Intercourse Dimension [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, 3, and 6]

      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 a modular part containing 6 scales which do not necessarily apply to all women with endometriosis; only 1 modular questionnaire (sexual intercourse [5 items]) was used in this study. The Sexual Intercourse dimension consists of 5 questions, each answered on the following scale: 0 = Never, 1 = Rarely, 2 = Sometimes, 3 = Often, 4 = Always, or Not Applicable (not scored). 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.

    14. Change From Baseline in Health-Related Productivity Questionnaire (HRPQ): Hours of Work Lost in Workplace and Household [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]

      The HRPQ consists of 9 questions measuring the impact of endometriosis-associated pain and its treatment on work productivity and daily activities in the home. Absenteeism: Number of hours of intended work lost due to illness or treatment. Presenteeism: Number of hours of work where output was impacted by illness or treatments. Total hours lost is the sum of hours missed due to absenteeism plus presenteeism.

    15. Number of Participants With Non-study Health Visits During the Treatment Period [6 months]

      The Health Resource Use Questionnaire (HRUQ) was used to collect information on non-study-related health visits that participants had during the study.

    16. Number of Days in Hospital During the Treatment Period [6 months]

      The Health Resource Use Questionnaire (HRUQ) was used to collect information on non-study-related health visits that participants had during the study, including physician visits, hospitalizations and types of procedures received.

    Outcome Measures

    1. Primary Outcome
    Title Percentage of Participants With a Response for Dysmenorrhea at Month 6 Based on Daily Assessment
    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.

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

    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.

    Title Change From Baseline in Endometriosis Health Profile-30 (EHP-30) Pain Dimension
    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.
