Long-term Use of Mifepristone in the Treatment of Adenomyosis

Official Title

A Multicenter Randomized Clinical Trial of Mifepristone Versus GnRHa for the Treatment of Adenomyosis

Brief Summary

      The design was a prospective, randomized, positive-control, parallel-group, multicenter
      clinical trial. The study included a randomized, parallel-group treatment for 24 weeks in 140
      subjects from eight hospitals in seven cities across the country who were diagnosed with
      Adenomyosis and associated symptoms (dysmenorrhea, with or without heavy menstrual flow) ,
      the subjects were randomly assigned to the following two groups:

        1. Study Group: mifepristone tablets, 10 mg, 1 tablet daily, taken orally (beginning on the
           third day of Menstruation) for 24 weeks;

        2. Control Group: dafinil (Triptorelin Acetate) , 3.75 mg, first injection on the third day
           of menstruation, followed by intramuscular injection every 28 days for 24 weeks.
