Accelerating Rare Disease Drug Development: Lessons Learned from Muscular Dystrophy Patient Advocacy Groups.

With scientific and molecular advancements related to disease pathogenesis, advances in gene and stem cell therapies, and the promise of lucrative markets for biopharmaceutical companies, there has been a rapid expansion in the number of potential new muscular dystrophy (MD) treatments. The first champion for a newly diagnosed MD patient and their caregivers is typically an MD-specific patient advocacy group (PAG). Muscular dystrophy PAGs have been among the most active in the rare disease drug development space.
