NCT01763099

Brief Summary

The purpose of this study is to evaluate the utility of treating patients experiencing graft failure after autologous hematopoietic stem cell transplantation with ex-vivo-expanded BM-drived mesenchymal stem cells from third-party donors or mesenchymal stem cells combined with cord blood. The first objective of this study was to evaluate the effect of such treatment on graft failure, and second object was to investigate the safety of such treatment.

Outcome Measures

Primary Outcomes (1)

  • hematopoietic recovery

    Hematopoietic reconstitution post-transplantation is defined as reconstitution of both neutrophil and platelet numbers. Neutrophil reconstitution is defined as occurring on the first 3 consecutive days with an neutrophil(NEU)\>0.5×10\^9/L, and platelet (PLT) reconstitution is defined as the first \>20×10\^9/L for 3 consecutive days.

    1 year

Secondary Outcomes (1)

  • infections, primary underlying disease relapse and any toxic side effects of MSCs treatment

    1 year

Study Arms (2)

Mesenchymal stem cells

EXPERIMENTAL

Mesenchymal stem cells group refers to treatment with mesenchymal stem cells (1×10\^6 cells/kg, intravenously)

Biological: Mesenchymal stem cells

Mesenchymal stem cells and cord blood

EXPERIMENTAL

Mesenchymal stem cells and cord blood group refers to treatment with mesenchymal stem cells (at a dose of 1×10\^6 cells/kg) and cord blood

Biological: Mesenchymal stem cells and cord blood

Interventions

Mesenchymal stem cells will be intravenously infused via a central venous catheter(at a dose of 1×10\^6 cells/kg, over 15 min) in day 1 and day 15 of the cycle. If the NEU and PLT levels do not attain the completely response(CR)standards after this cycle, mesenchymal stem cells combined with cord blood will be given. If the NEU and PLT levels attain the completely response(CR)or partly response(PR) standards after this cycle, another cycle with the same strategy will be given.

Mesenchymal stem cells

Mesenchymal stem cells will be given (at a dose of 1×10\^6 cells/kg,intravenously infused via a central venous catheter)on day 1.day 15, day 29 and day 43 of the cycle. Cord blood will be given intravenously infused via a central venous catheter on day 2 of the cycle.
