Thrombotic Thrombocytopenic Purpura, Acquired Clinical Trial
Official title:
The Efficacy and Safety of Bortezomib as First-line Treatment for Acquired Thrombotic Thrombocytopenic Purpura
To evaluate the efficacy and safety of bortezomib in the first-line treatment of patients with acquired TTP，we design this prospective, multi-center, single-arm interventional study.All enrolled TTP patients were given bortezomib 1.3 mg/m2 intravenous injection d1, 4, 8, on the basis of standard single membrane plasma exchange (2L/d) and hormone therapy (1mg/kg prednisone or equivalent methylprednisolone). 11 (4 doses in total). Bortezomib should be administered immediately after each plasma exchange, and the interval between the next plasma exchange is> 24h. Plasma exchange continued until the patient's platelet count was >100×109/L for 2 consecutive days, and then changed to once every other day for a total of two times and then stopped.
