Azacitidine in Combination With Venetoclax Treatment for Prevention of Relapse in MRD Positive Post Allogeneic Hematopoietic Stem Cell Transplantation Acute Myelogenous Leukemia/ Myelodysplastic Syndrome Patients
In patients with MRD-positive patients after AML/MDS allogeneic hematopoietic stem cell transplantation, azacytidine combined with venetoclax may be effective in eliminating micro residual diseases, reducing the risk of relapse, and ultimately improving long-term survival.The primary purpose of this study was to explore an effective protocol to reduce the risk of relapse in patients with MRD positive after allogeneic hematopoietic stem cell transplantation for AML/MDS.
• Patients between 18 years old and 65 years old.
• Patients with AML or MDS diagnosed according to WHO diagnostic criteria.
• Patients who received allogeneic hematopoietic stem cell transplantation and achieved complete remission.
• MRD was positive after transplantation, MFC \> 0.1% and / or fusion gene and gene mutation (WT1 \> 0.6%, AML1-ETO \> 0.4%, others \>1%).
• ECOG body status score 0-2.
• Patients with expected survival time \>=3 months.
• Good organ function level: ANC (neutrophil absolute value \>=1.0x10\^9/L; PLT \>=30x10\^9/L; HB \>=80g/L; Tibil \<=1.5 ULN; ALT / AST \<=2.5 ULN; bun / Cr \<=1.5 ULN; LVEF \>=50%).
• Patients who have received any anti-tumor treatment (including radiotherapy, chemotherapy, surgery or molecular targeted treatment) for more than 4 weeks from the end of the previous treatment.
• Patients with no GVHD and no previous history of 3 or more degrees of aGVHD. 10. Patients who voluntarily participate in the clinical trial, understand the research procedure and can sign the informed consent in writing.
