HVA vs IA/DA or VA in the Treatment of ND HR-AML

The Efficacy and Safety of Homoharringtonine Combined With Venetoclax and Azacitidine Versus Standard Chemotherapy or VA in the Treatment of Acute Myeloid Leukemia With High-risk, a Multicenter, Prospective, Randomized Study

The aim of this study is to evaluate the safety and efficacy of homohartonine combined with venetoclax and azacitidine (HVA) versus intensive chemotherapy (IA/DA) or venetoclax combined with azacitidine (VA) in newly diagnosed high-risk AML patients.

The HVA regimen exerts a synergistic pro-apoptotic effect and has demonstrated significant clinical efficacy against R/R AML and also overcomes adaptive resistance observed in the VA regimen. Exploratory work with small sample sizes in first-line settings suggests that combination of HHT and Ven+AZA exhibits potent anti-AML effects with good safety profiles, particularly in overcoming the impact of high-risk factors associated with AML relative to standard treatments. This indicates its potential as a more ideal option for the treatment of newly diagnosed AML with high risk factors. Therefore a prospective, multi-center, randomized controlled clinical study is planned to evaluate the efficacy and safety of the HVA regimen compared to intensive chemotherapy (IA/DA) or Venetoclax plus azacitidine (VA) regimens in newly diagnosed high-risk fit-AML or unfit AML patients.
