This protocol applies to patients diagnosed with Duchenne muscular dystrophy (DMD) whose underlying genetic mutation is amenable to exon 53 skipping — a specific subset of the DMD population identifiable through molecular genetic testing.
Management in this setting involves an antisense oligonucleotide (ASO) exon-skipping therapy specifically approved for the exon 53-amenable DMD population. The full treatment selection criteria, sequencing, and monitoring guidance are available in the complete protocol.
