Overview

The purpose of this study is to determine the efficacy and safety of Ruxolitinib and Chidamide intensified conditioning regimen in patients with Acute B cell Lymphoblast leukemia Underwenting Haploidenticl Peripheral blood Stem Cell Transplantation.

Haploidenticl Peripheral blood Stem Cell Transplantation should be offered to eligible patients with Acute B cell Lymphoblast leukemia whenever feasible. To further improve the outcome of transplantation patients with Acute B cell Lymphoblast leukemia, we developed a modified Bu/Cy conditioning regimen intensified by Ruxolitinib and Chidamide. In this study, we tested the efficacy and feasibility of the modified Bu/Cy conditioning regimen intensified by Ruxolitinib and Chidamide in patients with Acute B cell Lymphoblast leukemia undergoing allogeneic peripheral blood stem cell transplantation.
