SAT-013 Segesterone Acetate (SA) Serum Levels with a Statistical Model of Continued Use of the SA/Ethinyl Estradiol (EE) Contraceptive Vaginal System

摘要

The novel, ring-shaped, contraceptive vaginal system (CVS; Annovera™), contains 103 mg of SA and 17.4 mg of EE, and delivers a mean dose of SA 0.15/EE 0.013 mg/day. The CVS was designed to last thirteen cycles in a 21 day-in/7 day-out regimen. Objectives of these analyses were to determine the amount of SA/EE remaining in the CVS after 13 cycles of use and to estimate the SA level in serum after 1 year of continuous use.
