VABu Conditioning in Elderly AML HSCT

This is an open-label, multi-center, single-arm clinical study evaluating the efficacy and safety of the VABu conditioning regimen in elderly patients (≥60 years) with acute myeloid leukemia (AML) undergoing allogeneic hematopoietic stem cell transplantation (HSCT). The VABu regimen consists of Venetoclax, Azacitidine, Semustine, Cytarabine, and Busulfan. All enrolled participants will receive the VABu regimen as conditioning therapy prior to HSCT. The study aims to enroll 20 participants from multiple centers in China. The primary objectives are to evaluate the overall response rate, cumulative relapse rate, overall survival, graft-versus-host disease (GVHD)-free relapse-free survival (GRFS), non-relapse mortality (NRM), incidence of acute and chronic GVHD, and reactivation rates of cytomegalovirus (CMV) and Epstein-Barr virus (EBV). Safety outcomes include treatment-related toxicities, such as bone marrow suppression, infection, and organ dysfunction.
