This is a Phase IIb multicenter, open-label, non-comparative trial of continuous daily oral 10 mg of ulipristal acetate (UPA) to evaluate its contraceptive efficacy as the primary method of contraception.
A Multi-center, Open-label, Non-comparative Study of the Safety and Contraceptive Efficacy of Continuous Daily Oral 10 mg of Ulipristal Acetate (UPA)
This is an open-label study being conducted at 18 centers. The dose of 10 mg was chosen for daily continuous use of ulipristal acetate (UPA). The study will enroll approximately 300 subjects to use the UPA for 6 months (182 days). In addition to contraceptive efficacy, safety, overall acceptability of the product, and the number of bleeding/spotting days will be assessed.

- Be in good general overall health with no chronic medical conditions that result in periodic exacerbations that require significant medical care.
- Be women between 18 and 35 years inclusive at the enrollment visit.
- Have regular menstrual cycles that occur every 21-35 days when not using hormonal contraception.
- If subject is postpartum or post-abortal, she must have one menstrual bleed prior to enrollment.
- Be seeking contraception, and willing to use the study drug as the only contraception method during their months of study participation.
- If using a ring, patch, pill, or implant prior to study treatment, the subject must discontinue the active hormone at least 4 days, and no more than 7 days, prior to study drug initiation. Note that for combined oral contraceptive users, placebo pills are not counted as active hormone.
- If using a hormonal intrauterine device (IUD) prior to study treatment, the IUD must be removed prior to study drug initiation; removal and study drug initiation can occur on the same day, but the subject must refrain from sexual intercourse for 7 days following IUD removal.
- If using a copper IUD prior to study treatment, the IUD must be removed prior to study drug initiation; removal and study drug initiation can occur on the same day. The IUD removal and study drug initiation must occur during the first 7 days of a spontaneous menses.
- If using a non-hormonal contraceptive method (e.g. condoms or withdrawal) prior to study treatment, drug initiation should occur within the first 7 days of a spontaneous menses.
- If the woman has received a long-acting injectable contraceptive (e.g. depomedroxyprogesterone acetate) during the 10 months prior to screening, she must have resumed cyclic spontaneous menses (two menstrual bleeds) since last injection.

- Understand and sign an (Institutional Review Board) IRB approved informed consent form prior to screening activities (including fasting blood draws).
- Have a diastolic blood pressure (BP) ≤95 mm Hg and systolic BP ≤145 mm Hg after 5 minutes in a sitting position at the enrollment visit. Hypertensive subjects who are treatment controlled and, in the judgment of the investigator, are good candidates require a waiver for participation.
- Have a body mass index (BMI) < 40 kg/m2.
- Be planning to have at least one act of heterosexual vaginal intercourse each month during study participation.
- Be willing to accept an unknown risk of pregnancy during study participation.
