Summary

This is a prospective, single-center, open-label, single-arm study, to evaluate the efficacy and safety of Anti-BCMA chimeric antigen receptor T cell therapy(BCMA CAR-T)for patients with relapse/refractory Immune thrombocytopenia(R/R ITP).

Description

Immune thrombocytopenia (ITP) is a disorder that can lead to easy or excessive bruising and bleeding. Approximately two-thirds of patients achieve remission after/during first-line therapies. However, the other part of patients could not achieve durable remission or even refractory to initial treatments. Those cases, known as relapse/refractory Immune thrombocytopenia (R/R ITP), undergo the heavy burden of disease which decreases the quality of life. Lots of pathogeneses take part in the occurrence of R/R ITP, and the most important one of them is antibody-mediated immune platelet destruction. As far as it is known,human platelet autoantibodies are mainly secreted by plasma cells, especially long-lived plasma cells. Researchers want to explore that can BCMA CAR-T help R/R ITP patients increase platelet count, reduce bleeding episodes and the dose of concomitant medications.
