Recruitment & Eligibility

• Status: ACTIVE_NOT_RECRUITING
• Sex: All
• Target Recruitment: 21

Inclusion Criteria

• Adults aged ≥ 18 and ≤ 70 years
• Patients diagnosed with AML according to 2016 WHO myeloid malignant disease diagnosis standard (Non-APL)
• Patients with AML must meet one of the following criteria, A or B:

A: Refractory AML disease was defined as follows: (1) failure to attain CR following exposure to at least 2 courses of standard or intensive induction therapy; or (2) bone marrow leukemia cell decline index (BMCDI) < 50% and > 20% after 1 course of standard or intensive induction therapy. B: Relapsed AML disease was defined as follows: (1) reappearance of leukemic blasts in the peripheral blood after CR; or (2) detection of ≥ 5% blasts in the BM not attributable to another cause (e.g., BM regeneration after consolidation therapy); or (3) extramedullary relapse.

• ECOG performance status score less than 3
• Expected survival time ˃ 3 months
• Patients without serious heart, lung, liver, or kidney disease
• Ability to understand and voluntarily provide informed consent

Exclusion Criteria

• Patients who are allergic to the study drug or drugs with similar chemical structures
• Pregnant or lactating women, and women of childbearing age who do not want to practice effective methods of contraception
• Active infection
• Active bleeding
• Patients with new thrombosis, embolism, cerebral hemorrhage, or other diseases or a medical history within one year before enrollment
• Patients with mental disorders or other conditions whereby informed consent cannot be obtained and where the requirements of the study treatment and procedures cannot be met
• Liver function abnormalities (total bilirubin > 1.5 times the upper limit of the normal range, ALT/AST > 2.5 times the upper limit of the normal range or patients with liver involvement whose ALT/AST > 1.5 times the upper limit of the normal range), or renal anomalies (serum creatinine > 1.5 times the upper limit of the normal value)
• Patients with a history of clinically significant QTc interval prolongation (male > 450 ms; female > 470 ms), ventricular heart tachycardia and atrial fibrillation, II-degree heart block, myocardial infarction attack within one year before enrollment, and congestive heart failure, and patients with coronary heart disease who have clinical symptoms and requiring drug treatment

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
Chidamide+AZA+HHT+AraC+G-CSF group	CAHAG regimen	The patients are randomized into the group. Patients whose last induction failure regimen is a demethylated agent combined with priming regimen enter the experimental group directly.
Placebo+AZA+HHT+AraC+G-CSF group	Placebo regimen	The patients are randomized into the group.

Primary Outcome Measures

Name	Time	Method
Complete remission without minimal residual disease (CR with MRD-)	At the end of Cycle 1 (each cycle is 28 days)	If studied pretreatment, CR with negativity for a genetic marker by RT-qPCR, or CR with negativity by MFC
Overall response rate (ORR)	At the end of Cycle 1 (each cycle is 28 days)	The overall response (completed remission without minimal residual disease, completed remission with incomplete blood count recovery, morphologic leukemia-free state and partial remission) rate achieved after one or two courses(28 days) induction therapy by CAHAG regimen.
Complete remission with incomplete hematologic recovery (CRi)	At the end of Cycle 1 (each cycle is 28 days)	All CR criteria except for residual neutropenia (,1.0\*10E9/L \[1000/uL\]) or thrombocytopenia (\<100\*10E9/L \[100 000/uL\])
Partial remission (PR)	At the end of Cycle 1 (each cycle is 28 days)	All hematologic criteria of CR; decrease of bone marrow blast percentage to 5% to 25%; and decrease of pretreatment bone marrow blast percentage by at least 50%.
Morphologic leukemia-free state (MLFS)	At the end of Cycle 1 (each cycle is 28 days)	Bone marrow blasts ,5%; absence of blasts with Auer rods; absence of extramedullary disease; no hematologic recovery required

Secondary Outcome Measures

Name	Time	Method
Duration of Response (DOR)	1 year	It is measured the time from initial response to subsequent disease progression or relapse.
Overall Survival (OS)	1 year	It is measured from the time of entry into this trial to the date of death from any cause; patients not known to have died at last follow-up are censored on the date they were last known to be alive.
Progression-Free Survival (PFS)	1 year	It is measured from the time from randomization to progression or death.
