Purpose

This is a multicenter, prospective, observational Phase 4 study in the United States. The study is designed to collect both medical history and prospective data on Duchenne muscular dystrophy (DMD) treatment outcomes in participants receiving delandistrogene moxeparvovec as part of clinical care, compared to participants with DMD receiving or prescribed to start chronic glucocorticoid treatment at baseline in routine clinical practice.
