Key facts

Disease & market context

Duchenne Muscular Dystrophy

400 US cases/yr · $2.1B North America DMD Treatment (2024)

Disease Overview

Duchenne muscular dystrophy affects ~16,000+ Americans, caused by dystrophin gene mutations. It is the most common childhood muscular dystrophy. Vertex acquired Exonics for CRISPR-based gene editing to restore dystrophin expression, a fundamentally different approach from gene replacement.

Therapeutic Landscape

DMD treatments: exon-skipping ASOs (Sarepta: eteplirsen, casimersen, golodirsen), gene therapy (Elevidys, Sarepta/Roche, $1B+ in 2024), steroids. Vertex's CRISPR approach (VX-981) aims for permanent genomic correction rather than transient gene expression. The approach is earlier stage but potentially more durable than AAV gene therapy.

Myotonic Dystrophy Type 1 (DM1)

Competitive Landscape

DM1 has no approved disease-modifying therapy; the competitive landscape is entirely pipeline-stage, split across three MOA classes targeting the CUG-expansion RNA toxicity of DMPK. Antibody-oligonucleotide conjugates (AOC): Avidity Biosciences' del-desiran (AOC 1001) is the furthest-advanced, a TfR1-antibody-siRNA conjugate in the Phase 3 HARBOR trial after positive MARINA readouts showing splicing correction and video hand-opening improvement. Dyne Therapeutics' DYNE-101 (FORCE platform TfR1-PMO) entered Phase 1/2 ACHIEVE and reported functional improvements in 2024. Oral small-molecule splicing modulators: Pepgen's PGN-EDODM1 (Phase 1 FREEDOM/FREEDOM2) uses enhanced delivery oligonucleotide chemistry for DMPK knockdown. Gene editing: Vertex's acquired Exonics program (CRISPR-based DMPK targeting), plus Entrada Therapeutics' ENTR-701 (Endosomal Escape Vehicle conjugate) in early clinical development. Sarepta also disclosed preclinical DM1 programs. Commercial threat sizing: Avidity leads by ~2 years clinical-timeline and has established TfR1-conjugate validation. Vertex's CRISPR approach competes on durability (potentially one-time dose versus chronic Q-weekly/monthly conjugate dosing) but faces longer regulatory path, CMC complexity for muscle-wide delivery, and safety scrutiny on off-target editing. Commercial wedge for Vertex is curative positioning; near-term share belongs to AOC/PMO conjugates.
