What this trial studies

The ItaliTTP registry is an observational, prospective, multicenter study that aims to better understand the natural history and clinical outcomes of patients with immune-mediated thrombotic thrombocytopenic purpura (iTTP) in Italy. It will enroll at least 132 patients experiencing either their first episode or a relapse of iTTP over a three-year period, with follow-up extending for another three years. Participants will undergo routine clinical assessments and laboratory tests, including ADAMTS13 analysis, to gather comprehensive data on disease severity and progression.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 12 years or older who are experiencing an acute episode of iTTP with severe ADAMTS13 deficiency.

Not a fit: Patients who do not have an acute episode of iTTP or have not signed the informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term management and outcomes of patients with iTTP, potentially improving patient care.

How similar studies have performed: While there have been studies on iTTP, this registry approach is novel in its comprehensive, multicenter observational design focused on long-term outcomes.
