Aim: To evaluate if additional cord blood transfusion could accelerate the hematopoietic reconstitution in severe aplastic anemia(SAA) patients receiving immunosuppressive therapy (IST).
Study design: open-labed, prospective, multicenter, randomized control study Number of subjects: 60 each group
Treatment:
IST group: ATG (Thymoglobuline®, Genzyme) 3.5mg/kg/d×5d plus oral cyclosporine A (CSA) Cord blood transfusion group: In addition to the same dose and course of ATG and CSA , one unit of cord blood having no more than 2 HLA-A, B or DRB1 mismatches is transfused 24h after last dose of ATG administration.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Severe Aplastic Anemia | Drug: Thymoglobulin Procedure: Cord blood Drug: Cyclosporine Oral Product | Phase 4 |
Eligible patients should be under 60 years old with confirmed SAA, without HLA matched siblings and previous ATG treatment history. Patients will be excluded if they present any fatal disease, including respiratory failure, heart failure, liver or kidney function failure et al or severely allergic to biologic products.
To evaluate if additional cord blood transfusion could accelerate the hematopoietic reconstitution in severe aplastic anemia(SAA) patients receiving IST therapy, 120 eligible patients will be randomized to two groups, the IST group and the cord blood transfusion group. Patients in the IST group receive standard IST which including ATG (Thymoglobuline®, Genzyme) 3.5mg/kg/d×5d plus oral cyclosporine A（CSA ) started from 5mg/kg/d and adjusted to maintain trough serum concentration of 200-300ng/ml. While patients in the cord blood transfusion group receive the same dose and course of ATG and CSA as the control group and one unit of cord blood having no more than 2 HLA-A, B and DRB1 mismatches is transfused 24h after last dose of ATG administration.
The neutrophil recovery day is defined as the first day of 3 consecutive days during which the absolute neutrophil count (ANC) is >0.5×109/L, without G-CSF adminstration. Platelet recovery day is defined to have occurred on the first of 7 consecutive days with a blood platelet count (BPC) of >20×109/L, without transfusion support. Response (CR, PR or NR) is evaluated on 3, 4, 6,9, 12, 18 and 24months after treatment.
The primary end point is the neutrophil recovery day and second end points are response rate (CR+PR), treatment related mortality, disease free survival and overall survival.

- neutrophil recovery day [ Time Frame: 5 days to 365 days ]
the first day of 3 consecutive days when the absolute neutrophil count (ANC) reaches 0.5×10^9/L, without G-CSF administration .
The day of first dose of ATG administration is record as day 0.
- overall response rate [ Time Frame: 3 months to 24 months ]overall response rate is the percentage of patients who acquire complete remission and partial remission according to the criteria of British Committee for Standards in Haematology (BCSH).
- overall survival [ Time Frame: 24month ]The length of time from the start of treatment for patients with SAA are still alive.
- Treatment related mortality [ Time Frame: 3months, 24months ]The death rate of patients because of treatment
