Over 7,000 rare diseases affect an estimated 30 million Americans, yet fewer than 5% have FDA-approved treatments. Clinical trials are often the only pathway to experimental therapy for rare disease patients. Orphan drug designation, natural history studies, and gene therapy trials are all active areas with dedicated patient advocacy organizations that can help navigate access.
