Inclusion criteria

Patients must meet all of the following criteria before entering the group:

1. At least 18 years old; 2. Based on the World Health Organization (WHO) 2016 classification, the patients who were confirmed by the morphology of bone marrow cells and met the diagnosis criteria of relapsed / refractory AML (refer to the Chinese diagnosis and treatment guidelines for relapsed and refractory acute myeloid leukemia (2017 version)), the diagnosis criteria of relapsed AML: after CR, the peripheral blood once again showed leukemia cells or the original / immature cells in bone marrow were more than 5% (except the bone marrow after consolidated chemotherapy) The diagnosis standard of refractory AML: the primary refractory disease that has not been completely relieved after two courses of chemotherapy induced by standard regimen (including cytarabine and an anthracycline or anthraquinone drug); 3. ECOG physical fitness score is ≤ 2 points ; 4 Estimated survival time ≥ 12 weeks; 5 The organ function level of subjects must meet the following requirements:

  • Blood routine test: WBC ≤ 30 × 109 / L (it is allowed to take hydroxyurea until 3 days before administration of test drug to stabilize WBC);
  • Blood biochemistry: serum creatinine (Scr) ≤ 1.5 × ULN or creatinine clearance rate (Ccr) ≥ 60 ml / min (using Cockcroft -Gault formula); alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) ≤ 2.5 × ULN (liver with leukemia cell infiltration ≤ 5 × ULN), total bilirubin (TBIL) ≤ 1.5 × ULN;
  • Electrolyte: the content of potassium, sodium, calcium and magnesium in the blood is within the normal value range of the laboratory (if the abnormal laboratory result judged by the researcher is of no clinical significance or can be controlled within the normal value range by drugs in the screening period, the subject can be included in the group);
  • Coagulation function: INR ≤ 1.5 × ULN, APTT < 10 seconds, PT < 3 seconds, FIB ≥ 1.5g/l (blood products or drugs are allowed to be corrected 3 days before administration of test drugs);
  • Friderica corrected QT value (QTC) for male ≤ 450 ms or female ≤ 470 MS;
  • LVEF≥ 50%;
  • Urinary protein < 2 + was detected in urine routine. If urinary protein ≥ 2 +, 24-hour urinary protein quantification is needed, and only when 24-hour urinary protein < 2g can be enrolled in the group; 6. The serum pregnancy test must be carried out within 28 days before receiving the first dose of study drug and the result must be negative. The women of childbearing age and the male subjects agree to adopt the routine and effective contraceptive measures during the whole study period and within 6 months after the treatment; 7. The subjects should be willing to provide effective diagnosis evidence before treatment or accept bone marrow puncture or biopsy for diagnosis, and accept bone marrow puncture or biopsy for efficacy evaluation after treatment; 8. Volunteer to participate in clinical research and sign informed consent in writing.

  • Major surgery or significant traumatic injury within 28 days prior to the first administration of the study treatment or maybe major surgery is needed during the study treatment period;
  • Concomitant drugs that may cause QTc prolongation or induce torsade de pointes (TdP) are required, in addition to antimicrobials used as standard therapy for the prevention or treatment of infection and other such drugs considered essential by the researchers;
  • The toxic and side effects caused by previous treatment did not recover to CTCAE ≤ 1, except for hair loss and other tolerable events judged by the researchers;
