Depending on the variant of the disease, patients are divided into 3 groups: A, B and C. Group A include patients with acute myeloid leukemia (AML) inv(16)(p13.1q22) or t(16;16)(p13.1;q22); CBFB-MYH11, group B - AML with t(8;21)(q22;q22.1); RUNX1-RUNX1T1, AML with normal karyotype with or without gene mutations (FLT3, NPM1, CEBPa) regardless of the allele ratio, and also AML with cytogenetic abnormalities not classified as those within groups A/C, group C - AML with myelodysplasia-related changes. Patients from group A receive treatment according to the scheme: 2 courses "7+3", 2 courses "FLAG", then - 6 courses of maintenance therapy according to the scheme "5+5". Patients from group B are given one course of "7+3". After that, their minimal residual disease (MRD) status is assessed. In case MRD negativity is achieved after the 1st course of "7 +3", randomization is carried out: branch 1

  • therapy is similar to therapy for patients from group A (4 courses of induction and consolidation + 6 courses of maintenance chemotherapy (CT), allogeneic hematopoietic stem cell transplantation (allo-HSCT) is not planned), branch 2 - performing allo-HSCT should be done as soon as possible (before the start of maintenance CT is most desirable). If MRD negativity is not achieved after the 1st course of "7+3", the patient is given CT according to the standard program, followed by mandatory allo-HSCT. Patients from group C are treated either according to the "Aza-Ida-Ara-C" scheme, or according to the "Ven-DAC /AZA" scheme, followed by mandatory allo-HSCT.


"7+3" regimen:

  1. Cytarabine 200 mg/m2 (IV continuous infusion over 24 hours), days 1-7
  2. Daunorubicin 60 mg/m2 (IV bolus), days 1-3

"FLAG" regimen:

  1. Fludarabine 25 mg/m2 (IV in 30 minutes), days 1-5
  2. Cytarabine 1500 mg/m2 (IV in 3 hours), days 1-5
  3. Granulocyte colony-stimulating factor 5 mcg/kg (subcutaneous injection), from day 6 until regression of cytopenia

"Aza-Ida-Ara-C" regimen:

  1. Azacitidine 75 mg/m2 (subcutaneous injection), days 1-3
  2. Idarubicin 3 mg/m2 (IV bolus), days 4-10
  3. Cytarabine 15 mg/m2 twice a day (subcutaneous injection), days 4-17


  1. Venetoclax 400 mg once daily (PO), days 1-28
  2. Either Azacitidine or Decitabine Azacitidine 75 mg/m2 (subcutaneous injection), days 1-7 Decitabine 20 mg/m2 (IV in 60 minutes). days 1-5

"5+5" regimen

  1. Cytarabine 50 mg/m2 twice a day (subcutaneous injection), days 1-5
  2. Mercaptopurine 30 mg/m2 twice a day (PO), days 1-5
