- 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)
