Study Details

Study Description

Brief Summary

The purpose of this study is to determine the efficacy and safety of combined ATG #antithymocyte globulin # regimen (5mg/kg divided from day -5 to day -2) for aGVHD(acute graft-versus-host disease ) prophylaxis in matched sibling donor peripheral blood stem cell transplantation (MSD-PBSCT).

Condition or Disease Intervention/Treatment Phase
  • Drug: Rabbit ATG
Phase 2

Detailed Description

Transplantation with G-CSF #Granulocyte colony stimulating factor #mobilized peripheral blood stem cell (PBSCT) has been a stable transplant setting with matched sibling donor transplantation. Unmanipulated haploidentical donor PBSCT (haplo-PBSCT) has been applied in patients with hematologic malignancies. In our previous cohort study, haplo-PBSCT was associated with lower incidence of severe acute GVHD and extensive chronic GVHD compared with matched sibling donor PBSCT (MSD-PBSCT). Haplo-PBSCT has the same GVHD prophylaxis regimen with MSD-PBSCT, except ATG. It suggested the potential advantage of ATG in prophylaxis of GVHD and improvement of long term quality of life of the transplant recipients, which motivate us to observe the efficacy of combined ATG regimen for GVHD prophylaxis in MSD-PBSCT.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 4-day ATG combined regimen

ATG combined regimen for prophylaxis of GVHD, includes ATG, MMF (Mycophenolate mofetil), CsA (cyclosporin A) and MTX (methotrexate). All recipients in this arm received ATG, CsA, mycophenolate mofetil, and short-term methotrexate for GVHD prophylaxis. ATG (Thymoglobuline, rabbit) was used as 1 mg/kg/d from day -5 to day -3 and 2 mg/kg/d on day -2. CsA (3 mg/kg, q12h, i.v.) was used from day -9, and the concentration was adjusted to 180-200 ng/mL. CsA was switched to oral administration when the patient's bowel function recovered. From day -9, 0.5 g of mycophenolate mofetil was administered orally from every 12 h, which was withdrawn on day +30. After graft infusion, MTX was given for all patients at 15 mg/m2 on day +1 and 10 mg/m2 on days +3, +6 and +11.

Drug: Rabbit ATG
ATG (Thymoglobuline, rabbit) was used as 1 mg/kg/d from day -5 to day -3 and 2 mg/kg/d on day -2.
