• Status: Unknown status
• Trial end date: 2018-07-30
• Target enrollment: 0
• Participant gender: Female

Summary

Objectives: To assess if the administration of ulipristal acetate (UPA) in users of the levonorgestrel-releasing intrauterine system (LNG-IUS) with breakdown bleeding or abnormal bleeding, could be able to inhibit the bleeding and if this effect will be sustainable up to three months after treatment.

Material and methods: A total of 32 women aged between 18-45 years, users of the LNG-IUS with breakdown bleeding, abnormal bleeding or prolonged bleeding (bleeding more than 14 days) or episodes of bleeding with intervals less than 24 days). The study is an experimental, double blind randomized (16 women will receive UPA 5 mg/day/5 days; 16 women will receive placebo/1 time/day/5 day). The women will invited to participated at the Family Planning clinic at the day they consulted with the complaint of bleeding. That day they will allocated at random to UPA or placebo group. They will oriented to fill out a bleeding calendar through 90 days after the pill intake. In addition a ultrasonography scan will be perform before the first day of pill intake and at 90 days after.

Statistical analysis: A a pilot study the sample was estimated in 26 women (13 at each group) based at the estimative of success of 0.95 with UPA and 0.35 with placebo with significance of 0.05 and power of 80%. The sociodemographic characteristics will be analyzed as mean and SD and will compared through Mann-Whitney, Yates χ2 and Fisher exact tests as apropriate. Also, a regression analysis (Poisson analysis) with the dependent significant variables. The established level of significance will be p < 0.05.
