Conditioning Regimen Containing Melphalan and Cladribine for Refractory / Relapsed AML
Study Details
Study Description
Brief Summary
This project is a prospective, multicenter, randomized controlled clinical study. The subjects were refractory / relapsed AML patients aged ≤ 60 years diagnosed by bone marrow cell morphology, immunology, genetics and therapeutic efficacy evaluation. The classical Bu / Cy scheme or MCBC scheme was used for pretreatment. The primary endpoint of the study was the 3-year recurrence-free survival rate after allogeneic hematopoietic stem cell transplantation, and the secondary endpoints were 3-year overall survival rate, recurrence rate, treatment-related mortality, and pretreatment-related toxicity.
