💬In plain words
What the trial is, and whether it could suit you
The major morbidities of allogeneic hematopoietic stem cell transplant with non-human leukocyte antigen (HLA) matched siblings are graft vs host disease (GVHD) and life threatening infections. T depletion of the donor hematopoietic stem cell graft is effective in preventing GVHD, but immune reconstitution is slow, increasing the risk of infections. An addback of donor CD45RA (naive T cells) depleted cells may improve immune reconstitution and help decrease the risk of infections.
