Scientists hunt for relapse clues in TTP Patients' immune cells
NCT ID NCT06945861
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at blood samples from 44 people with thrombotic thrombocytopenic purpura (TTP) to understand how certain immune cells (B and T lymphocytes) react to the ADAMTS13 protein during different stages of the disease. The goal is to find early warning signs that could predict a relapse, so doctors can personalize treatment to keep patients in remission longer. Participants must be over 18 and treated at Rouen University Hospital.
