Multicenter National Immune Thrombocytopenia Registry and Biospecimen Collection

What this Trial Is About

Immune thrombocytopenia ITP is a rare blood disorder caused by an autoimmune condition that reduces platelet counts, increasing the risk of bleeding or prolonged bleeding. New treatments for ITP have emerged recently, but existing clinical studies are limited in their applicability to everyday patient care due to strict criteria. This registry aims to collect real-world clinical data and biospecimens from patients with various types of ITP to improve understanding of diagnosis, therapy, and patient outcomes in routine treatment. The registry includes patients diagnosed with primary or secondary ITP who consent to participate. Data collection occurs at defined points in the disease course either prospectively or retrospectively up to 12 months after diagnosis, provided continuous documentation is available. Biospecimens are collected and stored systematically to support research. Clinical information collected includes disease characteristics, treatment types, complications, quality of life, fatigue scores, and survival data over a follow-up period of up to 5 years. Participants provide clinical data and biosamples at enrollment, then again at 6 months and annually for up to 5 years. Assessments include platelet counts, bleeding and thromboembolic events, laboratory markers such as specific antibodies, and patient-reported outcomes like quality of life and fatigue. The study gathers epidemiological data on incidence, age, sex distribution, causes of ITP, treatment received, and remission status. The registry helps advance knowledge about ITP through long-term monitoring and standardized data collection.
