The North America Duchenne Muscular Dystrophy (DMD) Treatment Market was valued at US$ 2.06 billion in 2024 and is projected to reach US$ 8.84 billion by 2033, growing at a remarkable CAGR of 20.2% from 2025 to 2033.

DMD is a severe, progressive genetic disorder characterized by muscle weakness and degeneration, predominantly affecting young boys. Despite being rare, the high disease burden and lack of curative therapies have made this area a focus of intensive research, innovation, and policy support. North America leads the global landscape due to advanced healthcare infrastructure, strong clinical research, high diagnosis rates, and the presence of leading pharmaceutical companies driving innovation in gene therapies, exon-skipping drugs, and novel treatment modalities.
