Endometriosis
About this trial
This is an interventional diagnostic trial for Endometriosis
Eligibility Criteria
Inclusion Criteria:
- Healthy pre-menopausal female subject.
- Age: 18 - 50 years (inclusive) at the first screening visit. For the subject > 45 years follicle stimulating hormone (FSH) will be investigated at the second screening visit to confirm the pre-menopausal status (FSH < 40 IU/L in serum).
- Body mass index (BMI ) above or equal 18, and below or equal 30 kg / m² at the first screening visit.
- Adequate venous access.
- Ability to understand and follow study-related instructions
- Agreement to use adequate non-hormonal contraception.
- Confirmation of the subject's health insurance coverage prior to the first screening examination/visit.
Exclusion Criteria:
- Incompletely cured pre-existing diseases for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study drugs will not be normal.
- Thrombophlebitis, venous / arterial thromboembolic diseases (particularly deep vein thrombosis, pulmonary embolism, stroke, myocardial infarction).
- Presence or history of prodromata of thrombosis (e.g. transient ischemic attack, angina pectoris).
- Known hypersensitivity to the study medications (active substances or excipients of the preparations).
- Regular intake of medication other than hormonal contraceptives.
- Use of systemic or topical medication or substances which oppose the study objectives or which might influence them within 4 weeks before first administration of the study medication,
- Smoking of more than 10 cigarettes daily; if the subject is a smoker: subject is older than 35 years

Administered Antibiotic
Administered Spermicide
Tampons
Investigate the pharmacokinetics effect of a vaginally administered antimycotic (miconazole) during the use of an intra-vaginal ring (IVR) releasing anastrozole (ATZ) and levonorgestrel (LNG)
Investigate the pharmacokinetics effect of a vaginally administered antibiotic (clindamycin) during the use of an IVR releasing ATZ and LNG
Investigate the pharmacokinetics effect of a vaginally administered spermicide (nonoxynol-9) during the use of an IVR releasing ATZ and LNG
Investigate the pharmacokinetics effect of the concomitant use of tampons during the use of an IVR releasing ATZ and LNG; investigate the pharmacokinetics over an extended IVR wearing period of 35 days
