Brief 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/refra...
Detailed 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,...
