Brief Summary

In this prospective study, 30 newly untreated elderly patients with acute myeloid leukemia(AML) who were not suitable for standard chemotherapy were enrolled to observe the efficacy and side effects of venetoclax (VEN) combined with azacytidine (AZA) and chemotherapy in newly treated elderly patients with AML. Overall survival (OS), complete remission rate/complete remission with incomplete recovery of blood cell count (CR/ CRi) were used as the primary endpoints, and time to response (TTR), duration of response (DOR), mortality, and recurrence rate were used as secondary endpoints,and the incidence of adverse events were evaluated.

Detailed Description

Induction therapy: venetoclax d1 100mg, d2 200mg, d3-28 400mg, po; azacytidine 75mg/m2, d1-7, sc. Consolidation therapy: Regimen A or B was chosen according to the wishes of the patients. In addition, venetoclax was used for 14 days for positive minimal residual disease(MRD) and 7 days for MRD negative.

regimen A: the first two cycles: venetoclax 400mg, d1-7/14, po; cladribine 5mg/m2, d1-3, ivgtt; cytarabine 10mg/m2, q12h, d1-10, sc; the last two cycles: venetoclax 400mg, d1-7/14, po; cytarabine 0.5-1.0g/m2, d1-3, ivgtt; regimen B: the first two cycles: venetoclax 400mg, d1-7/14, po; cytarabine 100mg/m2, d1-5/7, ivgtt; idarubicin 8mg/m2, d1-2/3, ivgtt; the last two cycles: venetoclax 400mg, d1-7/14, po; cytarabine 0.5-1.0g/m2, d1-3, ivgtt; If the patient's ECOG performance status ≥2, the reduction of regimen IA(cytarabine+idarubicin)was 5+2. Maintenance therapy: azacytidine 75mg/m2, d1-7, sc.
