Clinical Trial Summary

PD-1/PD-L1 pathway play an important role in Inhibiting the function of antigen-specific CD8+T cells, thus matter a lot in immune escape. We intend to use PD-1 antibody to improve the function of lymhocyte and improve the chimerism in patients after allo-HCT.


Clinical Trial Description

Mixed chimerism is a trouble condition after allogeneic hematopoietic cell transplantation (Allo-HCT),all targeted treatment are aimed to improve the function of lymphocyte recipient. PD-1 antibody was reported to restored the function of impaired lymphocyte. Therefore, we want to use PD-1 antibody to improve the function of lymhocyte and improve the chimerism in HLH patients after allo-HCT. ;
