Combination of Venetoclax, Hypomethylation Agent and Low-dose Cytarabine as a Salvage Therapy for Acute Myeloid Leukemia

May 4, 2022 updated by: Xiao-Ning Gao, Beijing 302 Hospital

A Study of Combination of Venetoclax, Hypomethylation Agent and Low-dose Cytarabine as a Salvage Therapy in Patients With Acute Myeloid Leukemia Who Had Relapsed/Refractory Disease or Positive Minimal Residual Disease

Although studies are ongoing to evaluate the efficiency and safety of venetoclax-based therapy, alone or in combination with hypomethylation agent or low-dose cytarabine, in relapsed/refractory acute myeloid leukemia, data are scarce and heterogenous. In this study, the investigators aimed to assess safety and response to a new venetoclax-based triple-drug combination regimen (venetoclax + hypomethylation agent + low-dose cytarabine) in acute myeloid leukemia patients who had relapsed/refractory disease or positive minimal residual disease.

Study Overview

Detailed Description

Although the promising activity of venetoclax-based therapy is well demonstrated in the treatment of previously untreated elderly or unfit patients with acute myeloid leukemia, there are few data on the efficacy of venetoclax-based salvage therapy in relapsed/refractory patients, which can be difficult to treat. To date, data on venetoclax as monotherapy or in combination with hypomethylation agent or low-dose cytarabine as a salvage regimen in relapsed/refractory AML are scarce and heterogenous. In this study, the investigators aimed to assess safety and efficiency of a new triple-drug combination regimen, venetoclax + hypomethylation agent + low-dose cytarabine, in patients with relapsed/refractory acute myeloid leukemia or persistent positive minimal residual disease in the salvage setting.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: venetoclax + Hypomethylation agent + low-dose cytarabine treatment group
patients treated with venetoclax combined with decitabine/azacytidine and low-dose cytarabine
Venetoclax was given at a dose of 400 mg/day for 28 days per cycle. Decitabine was given at a dose of 20 mg/m2/day for 5 days (n=3) or azacytidine (n=8) was given at a dose of 75 mg/m2/day for 7 days at the discretion of the treating physician. Cytarabine was given at a dose of 10 mg/m2 twice daily for 7 days.
Other Names:
  • Venetoclax (ABT-199, GDC-0199)
  • Decitabine (Dacogen, 5-aza-2-deoxycytidine)
  • Azacitidine (5-Azacytidine, Ladakamycin)
  • Cytarabine (Cytarabine hydrochloride)
