Exclusion Criteria:

1. Female who is lactating

7. Post-menopausal status (minimum of a year without menses) and/or has undergone a complete hysterectomy or bilateral oophorectomy

8. Seated blood pressure higher than 140/90 mmHg at the Screening visit and prior to the first vaginal ring insertion, unless deemed non-significant by an Investigator

9. History of significant hypersensitivity to ethinyl estradiol, etonogestrel, or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions (like angioedema) to any drugs

10. Presence or history of significant genital, gastrointestinal, liver or kidney disease, or any other condition that is known to interfere with drug absorption, distribution, metabolism or excretion, or known to potentiate or predispose to undesired effects

11. History of significant cardiovascular, pulmonary, hematologic, neurological, psychiatric, endocrine, immunologic, or dermatologic disease, as defined by the Investigator

12. Presence of clinically significant ECG abnormalities at the Screening visit, as defined by the Investigator

13. Known presence or history of thrombophlebitis or any thromboembolic disorders (eg, venous thrombosis, arterial thrombosis), with or without pulmonary embolism

14. Known predisposition for venous or arterial thrombosis, with or without hereditary involvement such as Activated Protein C-resistance (including Factor V Leiden), antithrombin-III deficiency, protein C deficiency, protein S deficiency, hyperhomocysteinemia, and antiphospholipid antibodies (anticardiolipin antibodies, lupus anticoagulant)

15. Known presence or history of classic migraine

16. Known presence of ocular lesion arising from ophthalmic vascular disease, such as partial or complete loss of vision or defect in visual fields

17. Known presence, suspected presence or history of cervical, breast, uterine, estrogen-dependent, or progestin-dependent cancer or other sex-steroid sensitive malignancies

18. Known presence or history of undiagnosed abnormal vaginal bleeding

19. Known presence of any condition that makes the use of the vaginal ring difficult such as prolapse of the uterine cervix, cystocele, and/or rectocele, severe or chronic constipation

20. Any other vaginal condition that would interfere with the vaginal ring or cause an increased health risk

21. Scheduled immunization with a Coronavirus Disease 2019 (COVID-19) vaccine during the study that, in the opinion of an Investigator, could potentially interfere with subject participation, subject safety, study results, or any other reason

22. Major surgery with prolonged immobilisation in the previous 6 months prior to the first vaginal ring insertion

23. Planned major elective surgery in the 3 months following removal of the vaginal ring

24. Maintenance therapy with any drug or significant history of drug dependency or alcohol abuse (> 3 units of alcohol per day, intake of excessive alcohol, acute or chronic)

25. Any clinically significant illness in the 28 days prior to the first vaginal ring insertion

26. Use of any prescription drugs in the 28 days prior to the first vaginal ring insertion, that in the opinion of an Investigator would put into question the status of the participant as healthy

27. Use of St. John's wort in the 28 days prior to the first vaginal ring insertion

28. Any history of tuberculosis

29. Positive test result for alcohol and/or drugs of abuse at Screening or prior to the first vaginal ring insertion

31. Serum ferritin value below 24 µg/L at Screening

32. Any other clinically significant abnormalities in laboratory test results at Screening that would, in the opinion of an Investigator, increase the subject's risk of participation, jeopardize complete participation in the study, or compromise interpretation of study data

33. Inclusion in a previous group for this clinical study

34. Intake of ethinyl estradiol or etonogestrel in the 28 days prior to the first vaginal ring insertion
