Venetoclax combined with CACAG regimen for newly diagnosed AML. Recipients were randomized and those entering the experimental group received azacytidine, cytarabine,aclacinomycin,chidamide,venetoclax and granulocyte colony-stimulating factor. Azacytidine was used as 75 mg/m2/day from day 1 to day 7. Cytarabine was used as 75-100 mg/m2 bid from day 1 to day 5. Aclacinomycin was used as 20 mg/day on days 1,3,5. Chidamide was used as 30 mg/day on days 1,4,8,11. Venetoclax was used as 400 mg/day from day 1 to day 14;Combined with posaconazole, reduced to 100 mg/day;Combined with voriconazole, reduced to 200 mg/day.Granulocyte colony-stimulating factor was used as 300 μg/day from day 0 until agranulocytosi recovery .

Idarubicin+cytarabine(IA) regimen or daunorubicin+cytarabine(DA) regimen for newly diagnosed AML.Recipients were randomized and those entering this group received IA or DA induction chemotherapy. With the IA regimen,recipients received idarubicin(8-10 mg/m2) for three days and cytarabine(75-100 mg/m2, every 12 hrs) for seven days. With the DA regimen,recipients received daunorubicin(60 mg/m2)for three days and cytarabine(75-100 mg/m2,every 12 hrs)for seven days.

1. Azacytidine (75 mg/m2/day, days 1 to 7).
2. Cytarabine (75-100 mg/m2 bid, days 1 to 5).
3. Aclacinomycin(20 mg/day, days 1,3,5).
4. Chidamide (30 mg/day , days 1,4,8,11).
5. Venetoclax (400 mg/day, days 1 to 14,Combined with posaconazole reduced to 100 mg/day,Combined with voriconazole reduced to 200 mg/day ).
6. Granulocyte colony-stimulating factor (300 μg/day, day 0 until agranulocytosis recovery)

Defined as the percentage of participants achieving a best overall response of complete response (CR) or CR with incomplete blood count recovery (CRi).Biological characteristics exploratory studies were analyzed by single-cell sequencing and Atac-seq. Further, according to European LeukemiaNet risk group, we analyzed the outcomes of patients by molecular subtype as a sub-group analysis.

Defined in accordance with the IWG Response Criteria in AML. Bone marrow blasts<5 percent; absence of blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count >1.0 x 109/L (1000/µL); platelet count >100 x 109/L (100,000/µL); independence of red cell transfusions.
