Prospective natural history studies track the course of a disease in a group of people over time, identifying demographic, genetic, environmental, and other variables, that correlate with its development and outcomes. Thorough understanding of a disease’s progression is the foundation upon which a clinical development program for drugs, biologics, medical foods, or medical devices is built.1
