Primary objective: Assess the efficacy of a levonorgestrel 52 mg intrauterine system (LNG20 IUS) as a treatment for heavy menstrual bleeding. Secondary objectives: Assess safety, tolerability, bleeding patterns, and continuation rates of LNG20 IUS in women using LNG20 IUS for heavy menstrual bleeding.
The study is a multicenter, open-label, evaluation of the efficacy and safety of LNG20 IUS for treatment of heavy menstrual bleeding.
