Abstract
Objective: The objective of this study was to identify the dose for a contraceptive patch that provides a predetermined level of ovulation suppression and cycle control and that is well tolerated. Study Design: In this randomized study, 610 subjects received 10-, 15-, or 20-cm2 patch dose sizes (20-cm2, Ortho Evra/Evra) (Janssen Pharmaceutica, NV Belgium) or Ortho-Cyclen/Cilest (Janssen Pharmaceutica, NV Belgium) for up to 4 cycles. As with Ortho-Cyclen, patch regimens included 21 dosing days (3 consecutive 7-day patches) followed by 1 dose-free week. Results: The patch regimens demonstrated a dose-response for ovulation suppression and cycle control. Presumed ovulation, determined on the basis of serum progesterone concentrations ≥3 ng/mL in cycles 1 and 3, occurred in 6.2% (Ortho Evra) and 7.2% (Ortho-Cyclen) of subjects. At cycle 3, breakthrough bleeding/spotting was reported by 10.5% and 15.0% of subjects, respectively. Compliance with each patch was superior to that with Ortho-Cyclen (all P <.001). All regimens had safety profiles typical of oral contraceptives. Conclusion: The 20-cm2 patch (Ortho Evra) provided ovulation suppression, cycle control, and safety similar to that of Ortho-Cyclen, with significantly better compliance.
