PDSA Patient Consented Natural History Study Registry

This global ITP registry study is FDA approved and developed in partnership with the National Organization for Rare Disorders (NORD) to follow ITP patients of all ages, in all phases of disease to learn more about the natural history of ITP. The goal of the registry is to learn more about the clinical characteristics of ITP, the incidence of co-morbidities, treatment patterns, adverse outcomes, how quality of life is impacted, how family and socioeconomics is affected, and how ITP patients respond to COVID-19 and vaccinations.  Note: The registry is in English only, currently.
