Clinical Study of Mitoxantrone Hydrochloride Liposome Injection in Subjects With Acute Myeloid Leukemia

This is an interventional treatment trial for Relapsed or Refractory Acute Myeloid Leukemia focused on measuring venetoclax; Mitoxantrone liposomes; Acute myeloid leukemia Read More

Inclusion Criteria:

1. AML confirmed by bone marrow cytology and pathology;
2. Meet the diagnostic criteria for relapsed and refractory AML. Diagnostic criteria for relapsed AML: leukemia cells reappeared in peripheral blood after complete remission or blast cells in bone marrow >0.05 (except for other reasons such as bone marrow regeneration after consolidation chemotherapy) or extramedullary leukemia cell infiltration. Diagnostic criteria for refractory AML: naive patients who were ineffective after 2 courses of standard regimens; patients who relapsed within 12 months after consolidation and intensive therapy after CR; patients who relapsed after 12 months but were ineffective after conventional chemotherapy; 2 or more Secondary relapse; persistent extramedullary leukemia;
3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2;
4. Liver and kidney function: Alanine aminotransferase (AST) and aspartate aminotransferase (ALT) ≤2.5 x upper limit of normal (ULN) (≤5 x ULN for patients with liver infiltrates); Total bilirubin ≤1.5 x ULN (≤3 x ULN for patients with liver infiltration); Serum creatinine ≤1.5 x ULN;
5. Normal cardiac function: left ventricular ejection fraction (LVEF) ≥ 45% assessed by echocardiography or radionuclide active angiography (MUGA);
6. Pulmonary function: dyspnea ≤ CTC AE grade 1 and SaO2 ≥ 92% in indoor air environment;
7. The expected survival time is greater than 3 months;
8. Patients voluntarily participated in this study and signed the informed consent.

Exclusion Criteria:

1. The subject had previously received any of the following anti-tumor treatments: a)Those who have previously received mitoxantrone or mitoxantrone liposome; b)Previously received doxorubicin or other anthracycline treatment, and the total cumulative dose of doxorubicin is more than 360 mg/m^2 (1 mg doxorubicin converted from other anthracycline drugs is equivalent to 2 mg daunorubicin or 0.5 mg idarubicin); c)Have received anti-tumor treatment (including chemotherapy, targeted therapy, hormone therapy, taking traditional Chinese medicine with anti-tumor activity, etc.) or participated in other clinical trials and received clinical trial drugs within 4 weeks before the first use of the study drugs;
2. Heart function and disease meet one of the following conditions: a)Long QTc syndrome or QTc interval > 480 ms; b)Complete left bundle branch block, grade II or III atrioventricular block; c)Serious and uncontrolled arrhythmias requiring drug treatment; d)New York Heart Association grade ≥ II; e)A history of myocardial infarction, unstable angina pectoris, severe unstable ventricular arrhythmia or any other arrhythmia requiring treatment, a history of clinically serious pericardial disease, or ECG evidence of acute ischemia or active conduction system abnormalities within 6 months before recruitment.
3. Identify patients with central nervous system invasion;
4. Other malignancies, except for effectively controlled non melanoma skin basal cell carcinoma, breast / cervical carcinoma in situ, and other malignancies that have been effectively controlled without treatment in the past five years;
5. Non controlled systemic diseases (such as active infection, non controlled hypertension, diabetes, etc.);
6. Human immunodeficiency virus (HIV) infection (HIV antibody positive);
7. Active hepatitis B and C infection (hepatitis B test: if there is a positive hepatitis B surface antigen or core antibody, add HBV DNA, and the hepatitis B virus DNA exceeds 1x10^3 copies/mL to exclude; hepatitis C: if the hepatitis C antibody is positive, further test HCV RNA, hepatitis C Viral RNA exceeding 1x10^3 copies/mL was excluded);
8. Hypersensitivity to any study drug or its components;
9. Pregnant women, lactating women, patients who refused to take effective contraceptive measures during the study;
10. Serious neurological or psychiatric history;
11. Unsuitable subjects for this study determined by the investigator.
