Summary

This early-stage study is testing whether clenbuterol, a drug used for breathing problems, is safe for people with facioscapulohumeral muscular dystrophy (FSHD). About 30 adults with FSHD will receive one of three doses of the drug. Researchers will monitor side effects, heart rate, blood pressure, and lab values to find a dose that people can tolerate.
