- •ECOG rating 0-3
- •Leukocyte ≤ 20×10^9/L (allowing hydroxyurea to lower leukocyte therapy); HB ≥ 70g/L, platelet ≥ 30×10^9/L (allow blood transfusion or supportive therapy such as erythropoietin/thrombopoietin, for those who have met all inclusion criteria but hemoglobin and/or platelet count are not fulfilled, discussion with the sponsor is required to determine the eligibility of the subject based on his/her risk and benefit)
- •Liver function: total bilirubin ≦ 1.5 x ULN; alanine aminotransferase ≦ 3 x ULN; aspartate aminotransferase ≦ 3 x ULN; (except for leukemia infiltration)
- •Renal function: endogenous creatinine clearance ≧60ml/min
- •the international normalized ratio ≤ 1.5, and the prothrombin time or activated partial thromboplastin time ≤ 1.5 × ULN
- •Tolerate bone marrow puncture and undergo the test at the time point required by the program
- •Patients who sign the informed consent form must have the ability to understand and be willing to participate in this study, and sign the informed consent form at the same time.
排除标准
- •Active aGVHD.
- •Patients with a history of myeloproliferative disorders (including myelofibrosis, essential thrombocythemia, polycythemia vera, chronic myeloid leukemia) or with BCR-ABL1 translocation
- •Concomitant central nervous system leukemia
- •Previous history of chronic hemolytic anemia or Coomb test (+) during the screening period
- •Patients who were allergic to azacytidine or CD47 inhibitors or experienced serious adverse reactions because of azacytidine or CD47 inhibitors
- •Simultaneous participation in another interventional clinical study, except for: only participate in an observational (non-interventional) clinical study; in the survival follow-up phase of an interventional study
- •Glucocorticoids for therapeutic purposes have been used within 7 days prior to the first treatment. Nasal spraying, inhalational, topical glucocorticoids or low-dose intravenous glucocorticoids (i.e., no more than 10 mg/day prednisone or equivalent doses) are permitted. Prophylactic use of glucocorticoids is permitted to avoid allergic reactions from medical interventions (e.g., intravenous contrast gents, chemotherapeutic drugs, or blood transfusions)
- •Live attenuated vaccines within 4 weeks prior to the first day of the study or planned for the treatment period, have undergone major surgical procedures (craniotomy, thoracic or open surgery) or are expected to receive major surgeries during the treatment period (except for PICC and deep vein catheterization)
- •Patients who have non-hematologic toxicity caused by previous anti-leukemia treatment and the toxicity is not returned to NCI CTCAE v5.0 grade 0 to 1 (except for hair loss, fatigue), have uncontrolled active bleeding, coagulation disorders, or require therapeutic treatment with anticoagulants (such as warfarin, low molecular weight heparin, antiplatelet drugs, etc.)
- •Presence of an active or suspected autoimmune disease or a history of the disease in recent 2 years (except for vitiligo, psoriasis, Hashimoto's thyroiditis or Grave's disease that do not require a systemic treatment within the last 2 years, hypothyroidism that only requires thyroid hormone replacement therapy, or type 1 diabetic subjects requiring only insulin therapy)
- •A history of primary immunodeficiency
- •A history of primary immunodeficiency
- •Uncontrolled concurrent diseases include, but are not limited to:
- •HIV infection (HIV antibody positive); Severe infections; Symptomatic congestive heart failure (New York Heart Association Grade II to IV) or poorly controlled arrhythmias that may pose a serious risk of cardiac arrest; Arterial hypertension (systolic blood pressure ≥ 160 mmHg or diastolic ≥ 100 mmHg) even with standardized treatment; Any arterial thromboembolic events, including myocardial infarction, unstable angina, cerebrovascular accident, or transient ischemic attack, occurred within 6 months prior to enrollment; History of deep vein thrombosis, pulmonary embolism, or any other severe thromboembolism within 6 months prior to enrollment; Any life-threatening bleeding events such as intracranial hemorrhage or grade 3 or 4 gastrointestinal/variceal bleeding events requiring transfusion, endoscopic or surgical treatment occurred within 6 months prior to enrollment; Subjects with evidence of portal hypertension or previous history of varicose vein bleeding; A history of gastrointestinal perforation and/or fistula within 6 months prior to enrollment.
- •Uncontrolled metabolic disorders or other non-malignant systemic diseases that lead to a higher risk and/or uncertainty in survival evaluation.
- •Hepatic encephalopathy, hepatorenal syndrome, or Child-Pugh grade B or more severe liver cirrhosis.
- •History of intestinal obstruction or the following: inflammatory bowel disease or extensive bowel resection, Crohn's disease, ulcerative colitis, or chronic diarrhea.
- •Other acute or chronic illnesses, psychiatric disorders, or abnormal laboratory test values that may result in poor adherence or increased risk associated with drug administration, or interference with the interpretation of study results, and who, based on investigator's judgment, are classified as ineligible for this study.
- •Acute or chronic active hepatitis B or C infection: HbsAg and/or HbcAb positive and HBV DNA above the upper limit of normal, HBV DNA is not within the normal range after treatment, hepatitis C virus (HCV) antibody positive and RNA positive
