About this study

Allogeneic hematopoietic cell transplantation (HCT) is one of the only curative intent therapies available for hematologic malignancies. HLA-matched sibling donors have historically offered the best clinical results but are unavailable for the majority of patients, while most patients do have readily available haploidentical donors. One of the risks of a haploidentical HCT is graft vs. host disease (GVHD), but it is difficult to reduce the incidence of GVHD without compromising the graft vs. leukemia (GVL) effect. The hypothesis of this study is that JAK inhibition with and without CTLA-4 Ig with haploidentical HCT may mitigate GVHD and cytokine release syndrome while retaining the GVL effect and improving engraftment.
