Duchenne Muscular Dystrophy Therapeutics segmentation by Type distinguishes the molecular modality used to restore or replace dystrophin. Exon-skipping antisense oligonucleotides (eteplirsen, viltolarsen) command the largest share because they convert an out-of-frame deletion into an in-frame transcript, delaying wheelchair dependence in amenable ~13% of patients; payers accept premium pricing given the prolongation of ambulation by ~2–3 years. Stop-codon read-through drugs (ataluren) target nonsense mutations (~10–15% of DMD), but commercial uptake is capped by heterogeneous efficacy signals and reimbursement restrictions, translating into mid-single-digit market share. Gene therapies—micro-dystrophin AAV vectors (SRP-9001, PF-06939926) and CRISPR/Cas9 editors—are fastest-growing yet collectively <5% of 2023 revenues because launch volumes remain gated by manufacturing scale-up, durability questions, and one-time pricing negotiations averaging US$3–4 million per treatment; nevertheless forecast CAGR >30% through 2030 as pivotal read-outs de-risk coverage. Finally, steroid-based pharmacological agents (deflazacort, prednisone) retain a defensive revenue base (~one-fifth of total) as chronic co-medication, though conversion to generics is eroding value.
