- Normal pap test result on file at Altasciences in the previous 12 months prior to the first vaginal ring insertion or normal pap test result at Screening
- Have no clinically significant diseases captured in the medical history or evidence of clinically significant findings on the physical examination (including breast and gynecological examination) and/or electrocardiogram (ECG), as determined by an Investigator
Exclusion Criteria:
- Female who is lactating
- Female who is pregnant according to the pregnancy test at Screening or prior to the first vaginal ring insertion
- Use of the following systemic contraceptives: oral, patch, or vaginal ring, in the 28 days prior to the first vaginal insertion and until completion of the study
- Use of hormone replacement therapy in the 28 days prior to the first vaginal insertion and until completion of the study

- Post-menopausal status (minimum of a year without menses) and/or has undergone a complete hysterectomy or bilateral oophorectomy
- 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
- 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
- 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
- History of significant cardiovascular, pulmonary, hematologic, neurological, psychiatric, endocrine, immunologic, or dermatologic disease, as defined by the Investigator
- Presence of clinically significant ECG abnormalities at the Screening visit, as defined by the Investigator
- Known presence or history of thrombophlebitis or any thromboembolic disorders (eg, venous thrombosis, arterial thrombosis), with or without pulmonary embolism
- 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)
- Known presence or history of classic migraine
- Known presence of ocular lesion arising from ophthalmic vascular disease, such as partial or complete loss of vision or defect in visual fields
- Known presence, suspected presence or history of cervical, breast, uterine, estrogen-dependent, or progestin-dependent cancer or other sex-steroid sensitive malignancies
- Known presence or history of undiagnosed abnormal vaginal bleeding
- 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
- Any other vaginal condition that would interfere with the vaginal ring or cause an increased health risk
- 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
- Major surgery with prolonged immobilisation in the previous 6 months prior to the first vaginal ring insertion
- Planned major elective surgery in the 3 months following removal of the vaginal ring
- 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)
- Any clinically significant illness in the 28 days prior to the first vaginal ring insertion
- 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
- Use of St. John's wort in the 28 days prior to the first vaginal ring insertion
- Any history of tuberculosis
- Positive test result for alcohol and/or drugs of abuse at Screening or prior to the first vaginal ring insertion
- Positive screening results to HIV Ag/Ab combo, hepatitis B surface antigen, or hepatitis C virus tests
- Serum ferritin value below 24 μg/L at Screening
- 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
- Inclusion in a previous group for this clinical study
- Intake of ethinyl estradiol or etonogestrel in the 28 days prior to the first vaginal ring insertion
- Intake of an IP in the 28 days prior to the first vaginal ring insertion
- Donation of 50 mL or more of blood in the 28 days prior to the first vaginal ring insertion
- Donation of 500 mL or more of blood (Canadian Blood Services, Hema-Quebec, clinical studies, etc.) in the 56 days prior to the first vaginal ring insertion
- Hemoglobin laboratory values below the lower limit of the reference at Screening -
