Outcome Measures
Primary Outcomes (1)
Changes in the Mean Daily Numerical Rating Scale (NRS) Scores for the Worst Endometriosis-related Pain.
Assessed daily by participants in an e-Diary. NRS is an 11-point scale, with 0 indicating no pain and 10 indicating the worst imaginable pain. Changes from baseline to cycle 4.
At baseline and at menstrual cycle 4 (around 4 months, each cycle is approximately 28 days)
Secondary Outcomes (78)
Changes in the Mean Daily Numerical Rating Scale (NRS) Scores for the Worst Endometriosis-related Pain on Days With Menstrual Bleeding and for the Worst Endometriosis-related Pain on Days With no Menstrual Bleeding
At baseline and at menstrual cycle 4 (around 4 months, each cycle is approximately 28 days)
Changes in the Mean Daily Numerical Rating Scale (NRS) Scores for the Worst Endometriosis-related Pain.
From baseline to menstrual cycle 4 (around 4 months, each cycle is approximately 28 days)
Changes in the Mean Daily Numerical Rating Scale (NRS) Scores for the Worst Dysmenorrhea.
From baseline to menstrual cycle 4 (around 4 months, each cycle is approximately 28 days)
Changes in the Mean Daily Numerical Rating Scale (NRS) Scores for the Worst Non-menstrual Pelvic Pain.
From baseline to menstrual cycle 4 (around 4 months, each cycle is approximately 28 days)
Changes in the Mean Daily Numerical Rating Scale (NRS) Scores for the Worst Dyspareunia on Days With Sexual Intercourse.
From baseline to menstrual cycle 4 (around 4 months, each cycle is approximately 28 days)

Eligibility Criteria
You may qualify if:
- Pre-menopausal females aged ≥18 years at time of signing informed consent(s) with regular menstrual cycles.
- Body mass index (BMI) of 18-42 kg/m2 (both inclusive) at screening.
- Initial confirmation of endometriosis by laparoscopy or laparotomy within the last 10 years before the run-in visit or visualization of persistent endometrioma by repeat ultrasound.
- Transvaginal ultrasound documenting a uterus with no clinically significant abnormalities and presence of at least one ovary with no clinically significant abnormalities (with the exception of endometrioma) at the run-in visit.
- Eligible participants experienced moderate to severe endometriosis-related pain, which was defined as at the run-in visit, the participant having an NRS score of ≥5 for the worst endometriosis related pain during the past menstrual cycle and at randomization, the participant having a mean daily NRS score of ≥4 for the worst endometriosis related pain during each run-in menstrual cycle.
You may not qualify if:
- Known bone diseases (e.g. osteoporosis, Paget's disease and osteomalacia) affecting bone resorption or bone formation markers.
- Any significant abnormal findings of heart examinations before randomization.
- History of mental illness including occurrence of acute psychosis, bipolar disorders and schizophrenia (except for well-controlled anxiety and/or depression with no changes to interventions for 6 months prior to start of run-in)
- History of impulse control disorders including pathological gambling, compulsive buying, hypersexuality, and binge eating or being identified with potential impulse control disorder by the questionnaire for impulsive-compulsive disorders (a score ≥2 for any sub-questions of Question 3 or a score ≥1 for any sub-questions of Question 4) prior to randomization.
- History of orthostatic hypotension or recurrent syncope.
