G.P.147 - Outcome measures for Duchenne muscular dystrophy from ambulant to non-ambulant: implications for clinical trials

Novel emerging therapies for Duchenne muscular dystrophy (DMD), such as antisense oligomer (AO) mediated exon skipping, have generated the need of understanding the natural history study of the targeted genotype subgroups. Most natural history studies are focused on ambulant subjects; therefore very little data exists on non-ambulant DMD. Specifically targeting skippable deletions, we aim to assess the natural history of DMD through a composite assessment tool capable of capturing disease progression beyond loss of ambulation.
