A Phase II Trial of Total Body Irradiation-Based Myeloablative Conditioning and Transplantation of Partially HLA-Mismatched Peripheral Blood Stem Cells for Patients With Hematologic Malignancies
In Brief
A Phase 2 clinical trial evaluating Peripheral Blood Stem Cell Transplant for Chronic Leukemia and 4 related conditions. Completed, enrolled 30 participants across 1 site.
Detailed Summary
In this study, patients will receive a myeloablative preparative regimen consisting of fludarabine and total body irradiation (TBI), followed by a T cell replete, mobilized peripheral blood stem cell (PBSC) allograft from a partially matched related donor. All patients will receive post-transplant Cy in addition to standard post transplant immunosuppression with tacrolimus and MMF. The treatment protocol will be essentially identical to the prior study, with the exception of the substitution of TBI for Busulfan. The investigators hypothesize that this change will significantly reduce the risk of HC, while maintaining the efficacy of the transplant.
