About

This research is being done to assess the therapeutic efficacy and safety of a promising (venetoclax and decitabine) versus conventional "7+3"chemotherapy in induction young patients with acute myeloid leukemia.

This study involves the following:

Venetoclax and decitabine (investigational combination) Cytarabine and idarubicin (per standard of care)

Full description

This is an open-label, multicenter, phase 2 randomized clinical trial to compare the therapeutic efficacy and safety of venetoclax and decitabine to the conventional induction chemotherapy (7+3 regimen) among fit, young adults with newly diagnosed acute myeloid leukemia (AML).

Conventional induction chemotherapy with idarubicin and cytarabine is the standard of induction chemotherapy for acute myeloid leukemia (AML).

The FDA has approved the combination therapy of venetoclax and decitabine for elderly (> 60 year old) patients with newly diagnosed AML not eligible for intensive chemotherapy. Venetoclax is an inhibitor of BCL-2 (B-cell lymphoma 2, a protein that initiates tumor growth, disease progression, and drug resistance), which can lead to cancer cell death. Decitabine, a demethylation agent, has the potential to synergically target leukemia stem cell populations when combined with venetoclax as its homologous drug azacytidine.

Participants will be randomly assigned to one of the different induction groups and followed with either consolidation chemotherapy or allogeneic hematopoietic stem cell transplantation after remission. After completion of study treatment, participants are followed up every 3 to 6 months for up to 2 years.

It is expected that about 188 people will take part in this research study.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

188 participants in 2 patient groups

Investigational ( venetoclax, decitabine)

Experimental group

Description:

Randomized participants will receive induction as decitabine on days 1-5 and venetoclax daily on days 1-28. Second Induction (if not reach complete remission, but the percentage of blaste cells in bone marrow decreased by more than 50%):Re-induction with pre-induction therapy. Consolidation: If patients with favorable risk and MRD (Minimal Residual Disease) negative or refuse to allo-HSCT (Hematopoietic stem-cell transplantation), intermediate-dose (2g/m2 q12h days 1-3) for 4 cycles. If patients with intermediate or poor risk or favorable risk but MRD positive, intermediate-dose cytarabine for 1-2 cycles and follow up with allo-HSCT. For patients with FLT3 mutation, gilteritinib can be combined with the follow-up treatment after the end of initial induction.

Treatment:

Drug: Decitabine for Injection

Drug: Venetoclax

Drug: Gilteritinib

Standard of Care (Conventional Induction "7+3")

Experimental group

Description:

Randomized participants will receive cytarabine and idarubicin per standard of care as follows: Induction: cytarabine on days 1-7 and idarubicin (12mg/m2) on days 1-3 . Second Induction (if not reach complete remission, but the percentage of blaste cells in bone marrow decreased by more than 50%): Re-induction with pre-induction therapy. Consolidation: If patients with favorable risk and MRD negative or refuse to allo-HSCT, intermediate-dose cytarabine (2g/m2 q12h days 1-3) for 4 cycles. If patients with intermediate or poor risk or favorable risk but MRD positive, intermediate-dose cytarabine for 1-2 cycles and follow up with allo-HSCT. For patients with FLT3 mutation, gilteritinib can be combined with the follow-up treatment after the end of initial induction.

Treatment:

Drug: Cytarabine

Drug: Idarubicin

Drug: Gilteritinib
