Inclusion Criteria

- Women of at least 18 years of age at the time of signing of informed consent
- Women with endometriosis confirmed by at least one of the two criteria:
. Visually-confirmed endometriosis within 10 years
. Imaging-confirmed endometriosis within 12 months prior to screening
- Both criteria regarding pain symptoms have to be fulfilled:
. At Visit 1: at least a score of 40 (for subjects not on hormonal treatment) on visual analogue scale (VAS; 4-week recall period) for endometriosis-associated pelvic pain (EAPP), and at least a score of 30 for subjects on hormonal treatment. Subjects are regarded to be on hormonal treatment if hormonal contraception was used any time during the 4 weeks prior to Visit 1.
. During the screening period (before randomization):
o At least 24 daily diary entries during the 28 consecutive days starting on the first day with menstrual bleeding on or after Visit 1
o A sum of at least 98 of the available entries in the endometriosis symptom
diary (ESD) item 1 (‘worst pain’ on the daily numerical rating scale [NRS]; 24-hour recall), corresponding to an average score of = 3.5 over the 28-day period
- Willingness to use only ibuprofen as rescue pain medication for EAPP, if required, according to investigator’s instruction
- Good general health (except for findings related to endometriosis) as proven by medical
history, physical and gynecological examinations and laboratory test results
- Normal or clinically insignificant cervical smear not requiring further follow up (a cervical smear has to be taken at screening visit or a normal result has to be documented within the
previous 6 months). Human papilloma virus (HPV) testing in subjects with atypical squamous cells of unknown significance (ASCUS) can be used as an adjunctive test.
Subjects with ASCUS can be included if they are negative for high-risk HPV strains.
- Willingness to use non-hormonal barrier method for contraception (here spermicide-coated
condoms) from screening visit until the end of the study. This is not required if adequate contraception is achieved by vasectomy of the partner or use of copper intrauterine device (IUD) or commitment to abstinence and refrain from using hormonal contraception.
9. Willingness to be trained/instructed in using barrier method of contraception (here
spermicide-coated condoms)
10. Willingness and ability to attend the scheduled study visits and comply with study
procedures

F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 120

Exclusion Criteria

- Pregnancy or lactation (less than three months since delivery, abortion, or lactation before start of treatment) OR wish for pregnancy during the study
- Hypersensitivity to any ingredient of the study drug and/or ibuprofen
- Contraindications to study drug (as described in the investigator brochure) and/or ibuprofen (based on the country-specific label)
- Presence of at least one of the following risks related to bilirubin metabolism and liver function at Visit 1:
? . Total bilirubin above upper limit of normal (ULN)
? . Glutamic oxaloacetic transaminase (GOT) / aspartate aminotransferase (AST) above ULN
? . Glutamic pyruvic transaminase (GPT) / alanine aminotransferase (ALT) above ULN
? . Alkaline phosphatase (AP) equal or above 2 times ULN
? . Positive results for a) hepatitis B virus surface antigen (HBsAg) or b) hepatitis C virus antibodies and mRNA (anti-HCV and HCV-mRNA)
. Any disease influencing bilirubin values such as thalassemia, Morbus Gilbert/Meulengracht, Crigler-Najjar syndrome, Rotor syndrome or other
genetic predispositions to altered bilirubin metabolism
- Presence of at least one of the following risks related to hyperandrogenemia at Visit 1
? . Total testosterone above 1.5 times ULN
? . Any disease influencing testosterone metabolism such as adrenogenital syndrome Diagnosed polycystic ovary syndrome (PCOS) based on
Rotterdam criteria or suspicion of polycystic ovaries (elements of the Rotterdam criteria but insufficient for diagnosis e.g. clinical features of PCOS
like hirsutism or biochemical features of PCOS like hyperandrogenemia or oligo-/amenorrhea or polycystic ovary)
- 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, for example impaired function of kidneys and liver, chronic bowel disease
- Any diseases or conditions that might interfere with the conduct of the study or the interpretation of the results (e.g. pain caused by other diseases such as uterine fibroids, fibromyalgia, chronic bowel disease)
- Any disease or condition that may worsen under treatment according to the assessment and opinion of the investigator
- Abnormal vaginal/genital bleeding in terms of regularity or heaviness (caused by organic reasons such as uterine fibroids or uterine polyps or undiagnosed; adenomyosis-related changes in regularity or heaviness of vaginal/genital bleeding are not an exclusion criterion)
- Suspicion of menopausal transition, such as absence of regular menstrual cycles based on investigator’s judgment (absence of information regarding menstrual bleeding pattern e.g. due to long term use of hormonal contraception and elevated FSH plasma concentrations
at screening are not an exclusion criterion)
- Uncontrolled thyroid disorders (well controlled hyper- and hypothyroid disorders, as proven by thyroid-stimulating hormone [TSH] at screening are allowed)
- Any medication that could result in excessive accumulation, increased or impaired metabolism, or altered excretion of the study drug or might interfere with the conduct of the study or the interpretation of the results such as:
? . Moderate or strong CYP3A4 enzyme and P-gp inducers (with an expected decrease in systemic exposure to 50% or less) (see Appendix 16.1)
? . Moderate or strong CYP3A4 enzyme and P-gp inhibitors (with an expected increase in systemi
