E.3 | Principal inclusion criteria |
1. Informed consent signed and dated prior to any trial-related procedures. 2. In good physical and mental health to participate in the trial. 3. Pre-menopausal females between the ages of 18-45 years (both inclusive) at the time of signing the informed consent. 4. A menstrual cycle of 24-35 days (both inclusive) based on observation made in the absence of drugs that can affect the cycle length (e.g. oral contraceptives) prior to the screening visit. 5. Body mass index (BMI) of 18-35 kg/m2 (both inclusive) at screening. 6.

Willing and able to use a non-hormonal single-barrier method (i.e. condom) for contraception from the start of screening to the end-of-treatment. This is not required if adequate contraception is achieved by vasectomy of the male sexual partner, surgical sterilisation (e.g. tubal ligation and blockage methods such as ESSURE) of the subject, or true abstinence of the subject (sporadic sexual intercourse with men requiring condom use). 9. Willing to avoid the use of vaginal douches or any other intravaginally administered medications or devices (except for tampons) from randomisation to the end of treatment. 10. Documentation of normal cervical cytology or negative human papilloma virus (HPV) results for high-risk viral subtypes upon presence of atypical squamous cells of undetermined significance, based on test(s) performed within 24 months of randomisation. 11. Willing and able to comply with trial procedures, including attending scheduled visits and adherence to treatment plan. |

Undiagnosed abnormal vaginal bleeding within the last 3 months of the screening visit. 6. History of recurrent bacterial, fungal or viral vaginal infection (i.e. ≥4 episodes within a year). 7. History of malignancy within 5 years prior to the screening visit, except for adequately managed basal cell carcinoma and squamous cell carcinoma of the skin. 8. History of orthostatic hypotension or recurrent syncope. 9. History of mental illness including occurrence of acute psychosis and bipolar schizophrenia (except for well-controlled mild or moderate anxiety and/or depression with no changes to interventions for 3 months prior to the screening visit). 10. History of sudden sleep onset episodes. 11. Known diagnosis of impulse control disorders including pathological gambling, compulsive buying, hypersexuality, and binge eating. 12. Known positive results of Human Immunodeficiency Virus (HIV) antibody tests. 13. Any other incidental, clinically significant abnormal findings than endometriotic / adenomyotic lesions identified at the screening MRI assessment (e.g. suspected tumour). 14. Any clinically significant abnormal findings from vital signs, blood tests of haematology and clinical chemistry at screening, including alanine aminotransferase (ALT) >2.5 times upper limit of normal (ULN) or bilirubin >1.5 times ULN or creatinine >1.5 times ULN. 15. Any clinically significant abnormal findings at physical examination at screening. 16. Any vaginal or vulvar lesions that would interfere with vaginal ring usage. 17. Current pregnancy as confirmed by a positive serum pregnancy test at screening or planning a pregnancy within the duration of the trial, or currently breast-feeding or less than 6 months post-partum prior to the screening visit. 18. Planned surgical treatment of endometriosis or adenomyosis during the duration of the trial. 19. Continuous use of strong opioids (e.g. morphine) and/or illicit drugs (e.g. marijuana and amphetamine) for more than 2 weeks within 6 months prior to the screening visit. 20. Alcohol abuse (>14 units of alcohol a week) within 2 years prior to the screening visit. 21. Previous or current participation in a clinical trial involving a non-registered investigational medicinal product within 1 month of screening. If the trial involves a hormonal drug, the exclusion criteria 1-4 shall apply. 22. Contraindications to MRI such as having internal/external metallic devices and/or accessories (e.g. cardiac pacemakers and leg braces). |
