This is an open-label,single center, clinical trial to evaluate the efficacy and safety of Venetoclax in combination with Azacitidine and Harringtonine in patients with sAML~The FDA has approved the combination therapy of Venetoclax and Decitabine/Azacitidine for elderly (> 60-year-old) patients with newly diagnosed AML not eligible for intensive chemotherapy. Venetoclax is an inhibitor of BCL-2 (B-cell lymphoma 2, a protein that initiates tumor growth, disease progression, and drug resistance), which can lead to cancer cell death.~Homoharringtonine (HHT), a plant alkaloid with antitumor properties originally identified nearly 40 years ago, has a unique mechanism of action by preventing the initial elongation step of protein synthesis. HHT has been used widely in China for the treatment of chronic myeloid leukemia (CML), acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS)~Participants will receive 1-2 cycles of intensive treatment and followed with consolidated therapy with the same regimen of 4-6 cycles.If CR is not achieved by induction therapy, re-induction therapy can be continued, and those who have not achieved CR after re-induction therapy will withdraw from the study. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) if the patient meets the criteria for transplantation during treatment and a suitable donor exists After completion of study treatment, participants are followed up every 3 months for up to 2 years.~It is expected that about 30 people will take part in this research study.
This research is being done to assess the therapeutic efficacy and safety of a promising regimen (Venetoclax combined with Azacitidine and Harringtonine) in patients with secondary AML~This study involves the following:~Venetoclax combined with Azacitidine and Harringtonine
