Outcome Measures

Primary Outcomes (1)

  • The total response rate

    Response rate is the ratio of CR and PR patients to all evaluated patients at the time point. CR,PR,NR and relapse is evaluated according to the guidelines for the diagnosis and management of adult aplastic anaemia from British Committee for Standards in Haematology (BCSH)

    Every 3 months to 24 months

Secondary Outcomes (4)

  • Neutrophil recovery time

    From day 0 until the first of 3 consecutive days

  • Infection rates

    1 year

  • Overall survival

    2 years

  • Treatment related mortality

    2 years

Study Arms (2)

ATG, Cy and cord blood transfusion group

EXPERIMENTAL

ATG 3mg/kg/d for 5 days Cy 50mg/kg/d for 2 days CSA Started from 5mg/kg/d and adjusted to maintain trough serum concentration of 200-400ng/ml One unit of cord blood having no more than 3 HLA-A,B and DRB1 mismatches is transfused 24h after last dose of ATG administration. Intervention: Drug: Rabbit ATG, Thymoglobuline (Genzyme) plus Cyclophosphamide plus CSA Biological: Cord blood transfusion

Drug: Rabbit ATG, (Genzyme)Drug: CyDrug: CsABiological: Cord blood

ATG and CSA group

ACTIVE COMPARATOR

ATG 3mg/kg/d for 5 days CSA started from 5mg/kg/d and adjusted to maintain trough serum concentration of 200-400ng/ml Intervention: Drug: Rabbit ATG, Thymoglobuline (Genzyme) plus CSA

Drug: Rabbit ATG, (Genzyme)Drug: CsA

Interventions

ATG is an infusion of rabbit-derived antibodies against human T cells, which is used in the prevention and treatment of acute rejection in organ transplantation and therapy of aplastic anemia

Also known as: Thymoglobuline, Anti-thymoeyteGlobulin
ATG and CSA groupATG, Cy and cord blood transfusion group
CyDRUG

Cyclophosphamide is a medication mainly used in chemotherapy. It is an alkylating agent of the nitrogen mustard type

Also known as: Cyclophosphamide, Cytophosphane
ATG, Cy and cord blood transfusion group
CsADRUG

CsA is an immunosuppressant drug widely used in organ transplantation to prevent rejection. It reduces the activity of the immune system by interfering with the activity and growth of T cells

Also known as: Ciclosporin A, Cyclosporine
ATG and CSA groupATG, Cy and cord blood transfusion group
Cord bloodBIOLOGICAL

Cord blood is blood that remains in the placenta and in the attached umbilical cord after childbirth. Cord blood is collected because it contains stem cells, which can be used to treat hematopoietic and genetic disorders

Also known as: Umbilical cord blood
ATG, Cy and cord blood transfusion group
