    Graft-versus-host disease (GVHD) remains the leading cause of post-transplantation mortality and morbidity after allogeneic hematopoietic cell transplantation (alloHCT), adding a huge economic burden and affecting quality of life, thus, in patients with no increased risk of relapse.


    In this study, researchers tested a new conditioning regimen, total bone marrow and lymphoid irradiation (TMLI) at 2000 cGy and post-transplant cyclophosphamide (PTCy) for the first or second CR.


    2000 cGy of total bone marrow and lymphoid irradiation (TMLI) and post-transplant cyclophosphamide (PTCy) are used in acute myeloid leukemia patients with first or second CR to reduce the risk of chronic GVHD by using PTCy while at the same time.


    Patient safety lead-in was performed first to ensure no unexpected toxicities, and expanded in the absence of dose-limiting toxicities (DLT)

    The results suggest that among 18 patients with a median age of 40 years (range 19-56 years), the highest-grade toxicities were Grade 2 Bearman's bladder toxicity and stomatitis


    Overall, this chemotherapy-free conditioning regimen, along with PTCy and tacrolimus, was safe with no non-relapse mortality (NRM), and preliminary results suggest an improvement in GRFS rates


    This chemotherapy-free conditioning regimen, along with PTCy and tacrolimus, is safe with no non-relapse mortality (NRM), and preliminary results suggest improved GRFS rates
