About this trial

This is an interventional treatment trial for Severe Aplastic Anemia focused on measuring ATG, SAA, immunosuppressive treatment, cyclosporine

Eligibility Criteria

1 Year - 18 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • clinical diagnosis of childhood acquired severe aplastic anemia(SAA)

Exclusion Criteria:

  • clinical diagnosis of no childhood acquired severe aplastic anemia(SAA)

Sites / Locations

  • Department of Pediatrics, Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical SciencesRecruiting

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

high dose ATG,low dose ATG

Arm Description

Outcomes

Primary Outcome Measures

the response and complete remission rate with different doses of ATG to treat child severe aplastic anemia
Complete response (CR) was defined as achieving normal levels of hemoglobin adjusted for age, platelet count >100×109/L, and ANC>1.5×109/L. Partial response (PR) was defined as transfusion independence, reticulocyte count >30×109/L, platelet count >20×109/L, and ANC >0.5×109/L above the baseline. Persistence of transfusion requirement or death was evidence of no response (NR).

Secondary Outcome Measures

the relapse rate with different doses of ATG to treat child severe aplastic anemia
relapse was defined as transfusion dependence again; or progressed to paroxysmal nocturnal hemoglobinuria (PNH) /acute myeloid leukemia/myelodysplasia syndrome (MDS); or CSA dependence

5. Study Description

Brief Summary
Severe acquired aplastic anaemia (SAA) is a life-threatening disease characterized by pancytopenia and hypoplastic bone marrow. Immunosuppressive treatment with antithymocyte globulin (ATG)and cyclosporine remain the standard regimen with response rates of 70% or more and excellent overall survival. However ,there are no clinical trials to illustrate the response and complete remission rate with different doses of ATG.And there are no data reported on children with SAA so far.
