A Single-Arm Phase 2 Study With Optimized Standard Protocol for Severe Aplastic Anemia — OSP  

Aplastic Anemia Clinical Trial

Official title:
A Single-Arm Phase 2 Study With Optimized Standard Protocol for Severe Aplastic Anemia

Clinical Trial Summary

Severe acquired aplastic anaemia (SAA) is a bone marrow failure disease characterized by pancytopenia and a hypocellular bone marrow. The corn pathophysiological mechanism is the destruction of hematopoietic stem/progenitor cells mediated by auto-reactive effector T cells. Immunosuppressive therapy with horse antithymocyte globulin (ATG) plus cyclosporine (CSA) is currently the standard of treatment in patients with aplastic anaemia who are not eligible for bone marrow transplantation and with response rates from 40% to 70%. Previous studies showed that horse ATG (hATG) is apparently more effective than rabbit ATG (rATG) as the latter has higher treatment related mortality (TRM). Unfortunately hATG is unavailable in China, so we conduct a optimized standard treatment (9 days protocol) of rATG plus CSA and Levamisole (LMS) Sequential maintaining (termed Optimized Standard Protocol, OSP) for severe aplastic anemia. This prospective study is designed to evaluate the efficacy and safety of Optimized Standard Protocol as first line therapy in newly diagnosed severe aplastic anemia patients.

Clinical Trial Description

During the treatment period, rATG is administered at a dose of 1.97 mg/kg/day for 9 days by slow intravenous infusion. CSA is administered orally at a dose of 3 mg/kg qod, and Levamisole was administered orally at a dose of 2.5 mg/kg qod. The CSA and Levamisole (LMS) is designed to alternately every other day. ;
