This trial is a prospective, multicenter, open-label, non-controlled trial in female subjects, including adolescents between the ages of 15+(inclusive) who present to the clinic seeking contraception, who are postmenarcheal and premenopausal.
At screening, informed consent will be obtained and the screening procedures will be performed. After confirmation of the subject's eligibility, the subject will be provided with the investigational product and trained in the use of an electronic diary. Afterwards, the subjects will attend visit the clinical site on Day 20±2 of the 1st, 3rd, 6th and 9th cycles and on Day 29+2 of the 13th cycle. The last clinical site visit will occur 10-14 days after the 13th cycle visit.
The trial will include women who have never used hormonal contraceptives before consent (naïve users), women who have not used hormonal contraceptives in the past three months before consent or who have used hormonal contraceptives in the past but have a contraceptive-free time of less than three months before consent (previous users) as well as women directly switching from another hormonal method (switchers). Women who have used hormonal contraceptives in the past but have a contraceptive-free time of less than three months before consent are allowed to be included into the trial if they had at least one complete menstrual cycle before enrollment.
A population pharmacokinetic (PK) analysis planned in the whole subject population, will obtain sparse blood samples to determine plasma concentrations. In total, four blood samples will be collected: two samples each will be collected during the 1st cycle and during the 6th cycle of treatment.
Adverse events and safety information will be collected throughout the study.
