Asteroid 6 Fibroid Study

 To take part in this clinical study, you have at least one uterine fibroid diagnosed within the last 3 months and you are suffering from at least one symptom of the uterine fibroid such as; heavy menstrual bleeding or you feel pressure or pain in your lower belly. The purpose of this study is to test the safety and efficacy of the long-term treatment with study drug called vilaprisan in treatment of uterine fibroids and any potential effect it may have on the health of the bones, such as bone loss. Also, this study will test the optimal duration of the treatment with study drug.

This study is considered research because the study drug has not yet been approved by the FDA in treatment of uterine fibroids. This study is one in a series of studies being done to obtain approval of vilaprisan for use in treatment of uterine fibroids.

You may be eligible to participate if you:

Are 18 years or older
