Brief Summary

This is a single-arm, open-label, Phase III study in approximately 100 sites in the United States (US) over seven cycles of use in women aged 18 to 35 years who are at risk of pregnancy.

Detailed Description

Through assessments including pelvic examination, laboratory procedures, and medical and gynecological history, subjects will be screened for eligibility in order to enroll approximately 1349 subjects into the study. After a screening period of up to 60 days, enrolled women will receive study drug. Each woman will participate in the study until after she has completed treatment during seven study cycles. Women who have individual cycles that do not meet the criteria for an evaluable cycle will not have those cycles replaced by subsequent cycles in order to provide a total of seven evaluable cycles.

  5. Have a negative urine pregnancy test at enrollment.

  6. Have normal, cyclic menses with a usual length of 21 to 35 days over the last two cycles or at least two consecutive spontaneous menses (21 to 35 days in length) since delivery, abortion, or after discontinuing hormonal contraception or hormonal therapy prior to the date of consent.

    4. If an intrauterine device (IUD) was recently removed, the subject must have had at least one spontaneous menses following removal and prior to the date of consent.
  7. Be willing to engage in at least three acts of heterosexual vaginal intercourse per cycle.

  8. Be willing to use the study drug as the only method of contraception over the course of the study (with the exception of emergency contraception [EC] in the event a subject engages in vaginal intercourse but believes that the study drug was not used properly or she is at risk for pregnancy for any other reason).

  9. Be capable of using the study drug properly and agree to comply with all study directions and requirements, including retaining the wrappers and returning them to the clinical site at the next study visit.

  10. Be willing to keep a daily electronic diary (eDiary) to record coital information, study drug use information, use of concomitant medications including other vaginal products and other contraceptives, menses, and sign and symptom data for the subject or as reported to her by her partner.

Less than 21 years of age. ii. A colposcopy (with or without biopsy) found no evidence of dysplasia requiring treatment or treatment was performed and follow up at least six months after the treatment showed no evidence of disease.

    c. Pap test in the past 12 months from the date of screening with atypical squamous cells in which high grade squamous intraepithelial lesion cannot be excluded (ASC-H), atypical glandular cells, high grade squamous intraepithelial lesion (HSIL), or ≥30 years old who are cytology negative and HPV 16- or HPV 18-positive unless colposcopy and/or treatment was performed and follow up at least six months after the colposcopy and/or treatment showed no evidence of disease.
