Ruxolitinib and Chidamide Intensified Bu/CY Conditioning Regimen

Ruxolitinib and Chidamide Intensified Bu/CY Conditioning Regimen for Patients With Acute B Cell Lymphoblast Leukemia Underwenting Haploidenticl Peripheral Blood Stem Cell Transplantation

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.

Study Overview

• Status: Recruiting
• Conditions: Peripheral Blood Stem Cell Transplantation
• Intervention / Treatment: Drug: Ruxolitinib combined with Chidamide.

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Proportion of participants relapse as assessed by NCCN (National Comprehensive Cancer Network ) criteria	Defined as the proportion of participants whose underlying malignancy relapsed.	365 days after transplantation

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
DFS(disease-free survival )	DFS was defined as survival with no evidence of relapse or progression.	365 days after transplantation
TRM(treatment-related mortality )	Defined as the proportion of subjects who died due to causes other than malignancy relapse.	365 days after transplantation
OS(overall survival )	OS was defined as the time from transplantation to death due to any cause.	365 days after transplantation
