We evaluated the efficacy and safety of a chemo-free combination of venetoclax, azacitidine and flumatinib (VAF) in patients with ND Ph+AL and accelerated or blast phase chronic myeloid leukemia(CML)....After one cycle of VAF, CR/CRi rate was 100% (13/13). Of the 13 patients, 92.3% had a molecular response with76.9% CMR and 15.4% MMR, and another one achieved a CCyR. The CMR rate at end of two cycles of VAF, the primary endpoint, increased to 83.3%....VAF is a highly effective and safe strategy to achieve early and deep molecular response in patients with ND Ph+AL in the frontline setting, providing a potential Day ward/Out-patient treatment strategy for Ph+AL.
