Eligibility

Inclusion Criteria:

• Premenopausal women18 years and above at the time of screening.
• Women with endometriosis confirmed by laparoscopy or laparotomy within the last ten years but not less than 8 weeks before the screening visit In Japan, diagnosis based on imaging (transvaginal ultrasound or MRI) also qualifies for inclusion.
• Moderate to severe endometriosis-associated pelvic pain (EAPP) of =5 in the last 28 days before screening visit 1 measured on the numeric rating scale (NRS; i.e. 4-week recall period).
• At randomization: Adherence to the study procedures during the screening period, at least 24 diary entries of ESD item 1 during the last 28 consecutive days before the randomization visit, and a sum of the available ESD item 1 ('worst pain' on the daily NRS) entries during this period of at least 98 (corresponding to an average score of = 3.5).
• Willingness to use only ibuprofen as rescue pain medication for EAPP, if needed according to investigator's instruction.
• Use of a non-hormonal barrier method (i.e. spermicide-coated condoms) for contraception from screening visit until the end of the study. This is not required if adequate contraception is achieved by vasectomy of the partner

Exclusion Criteria:

• Pregnancy or lactation (less than three months since delivery, abortion, or lactation before start of treatment)
• Any diseases or conditions that can compromise the function of the body systems and could result in altered absorption, excessive accumulation, impaired metabolism, or altered excretion of the study drug
• Any diseases or conditions that might interfere with the conduct of the study or the interpretation of the results.
• Any disease or condition that may worsen under hormonal treatment according to the assessment and opinion of the investigator.
• Undiagnosed abnormal genital bleeding
• Wish for pregnancy during the study
• Regular use of pain medication due to other underlying diseases
• Non-responsiveness of endometriosis associated pelvic pain (EAPP) to GnRH-a or surgery (partial response is not exclusionary).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Absolute Change in Mean Pain of the 7 Days With Worst EAPP From Baseline (Last 28 Days Before Randomization) to End of Treatment (Last 28 Days of Treatment Period, Days 57-84) as Measured on NRS by Question 1 of ESD	Pain intensity was assessed on 11-point (0-10) NRS by question 1. In question 1, participants were asked to rate the pain in the target area during the past 24 hours, where 0= no pain and 10= worst imaginable pain and responses were recorded in ESD. The mean pain of the 7 days with worst EAPP within a 28-day window was calculated as the sum of ESD item 1 on 7 days with worst EAPP within that 28-day window divided by 7.	Baseline (last 28 days before randomization), end of treatment (Treatment 3) (last 28 days of the treatment period, Day 57-84)
Secondary	Absolute Change in Mean Pain of the 7 Days With Worst EAPP From Baseline (Last 28 Days Before Randomization) to First Cycle Under Study Treatment (Day 1-28) and to Second Cycle Under Study Treatment (Day 29-56) as Measured on NRS by Question 1 of ESD	Pain intensity was assessed on 11-point (0-10) NRS by question 1. In question 1, subjects were asked to rate the pain in the target area during the past 24 hours, where 0= no pain and 10= worst imaginable pain and responses were recorded in ESD. The mean pain of the 7 days with worst EAPP within a 28-day window was calculated as the sum of ESD item 1 on 7 days with worst EAPP within that 28-day window divided by 7.	Baseline (last 28 days before randomization), first cycle (Treatment 1) (Day 1-28), second cycle (Treatment 2) (Day 29-56)
Secondary	Absolute Change in Mean Pain From Baseline (Last 28 Days Before Randomization) to First Cycle Under Study Treatment(Day1-28), Second Cycle Under Study Treatment(Day29-56),Third Cycle Under Study Treatment (Day57-84) as Measured on NRS by Question1 of ESD	Pain intensity was assessed on 11-point (0-10) NRS by question 1. In question 1, subjects were asked to rate the pain in the target area during the past 24 hours, where 0= no pain and 10= worst imaginable pain and responses were recorded in ESD. The mean pain within a 28-day window was calculated as the sum of ESD item 1 within that 28-day window divided by the number with non-missing days within that 28-day window. Here, number of subjects 'n' signifies evaluable subjects for the respective category.	Baseline (last 28 days before randomization), first cycle (Treatment 1) (Day 1-28), second cycle (Treatment 2) (Day 29-56), and third cycle (Treatment 3) (last 28 days of the treatment period, Day 57-84)
Secondary	Percentage of Days During Baseline (Last 28 Days Before Randomization) and Cycles 1, 2, and 3 With Pain Greater Than or Equal to (>=) 7 as Measured on NRS by Question 1 of ESD as Measured on NRS by Question 1 of ESD	Pain intensity was assessed on 11-point (0-10) NRS by question 1. In question 1, subjects were asked to rate the pain in the target area during the past 24 hours, where 0= no pain and 10= worst imaginable pain and responses were recorded in ESD. The percentage of days with pain >=7 within a 28-day window was calculated as 100 divided by the number of non-missing days within that 28-day window multiplied by the number of days within that 28-day window where item 1 of the ESD was >=7.	Baseline (last 28 days before randomization), Cycle 1 (Treatment 1), Cycle 2 (Treatment 2), and Cycle 3 (Treatment 3)
Secondary	Change From Baseline (Last 28 Days Before Randomization) to Cycle 1, 2, and 3 in Percentage of Days With Pain >=7 as Measured on NRS by Question 1 of ESD	Pain intensity was assessed on 11-point (0-10) NRS by question 1. In question 1, subjects were asked to rate the pain in the target area during the past 24 hours, where 0= no pain and 10= worst imaginable pain and responses were recorded in ESD. The percentage of days with pain >=7 within a 28-day window was calculated as 100 divided by the number of non-missing days within that 28-day window multiplied by the number of days within that 28-day window where item 1 of the ESD was >=7. Here, number of subjects 'n' signifies evaluable subjects for the respective category.	Baseline (last 28 days before randomization), Cycle 1 (Treatment 1), Cycle 2 (Treatment 2), and Cycle 3 (Treatment 3)
Secondary	Percentage of Days During Baseline (Last 28 Days Before Randomization) and Cycles 1, 2, and 3 With Pain >=4 as Measured on NRS by Question 1 of ESD	Pain intensity was assessed on 11-point (0-10) NRS by question 1. In question 1, subjects were asked to rate the pain in the target area during the past 24 hours, where 0= no pain and 10= worst imaginable pain and responses were recorded in ESD. The percentage of days with pain >=4 within a 28-day window was calculated as 100 divided by the number of non-missing days within that 28-day window multiplied by the number of days within that window where Item 1 of the ESD was >=4. Here, number of subjects 'n' signifies evaluable subjects for the respective category.	Baseline (last 28 days before randomization), Cycle 1 (Treatment 1), Cycle 2 (Treatment 2), and Cycle 3 (Treatment 3)
Secondary	Change From Baseline (Last 28 Days Before Randomization) to Cycle 1, 2, and 3 in Percentage of Days With Pain >=4 as Measured on NRS by Question 1 of ESD	Pain intensity was assessed on 11-point (0-10) NRS by question 1. In question 1, subjects were asked to rate the pain in the target area during the past 24 hours, where 0= no pain and 10= worst imaginable pain and responses were recorded in ESD. The percentage of days with pain >=4 within a 28-day window was calculated as 100 divided by the number of non-missing days within that 28-day window multiplied by the number of days within that window where Item 1 of the ESD was >=4.
