Brief summary: This phase II trial studies how well the combination of based decitabine and olverembatinib（HQP1351)chemotherapy work for the treatment of blast phase or accelerated phase chronic myelogenous leukemia. Drugs used in chemotherapy such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. HQP1351 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving decitabine and ponatinib based chemotherapy may help to control blast phase or accelerated phase chronic myelogenous leukemia.

Detailed description: Accelerated Phase CML treated with decitabine10mg/m2 d1-5 intravenously (IV) over 60 minutes on days 1-5 and olverembatinib（HQP1351) 40mg qod every 28 days.After completion of HQP1351 lead-in, patients will receive HQP1351 PO daily on days 1-28 of subsequent cycles.

chronic myeloid leukaemia in blast phase:treated with decitabine 20mg/m2 d1-5 intravenously (IV) over 60 minutes on days 1-5 and HQP1351 40mg qod every 28 days,with or without other chemotherapy drugs

Eligibility criteria: Inclusion Criteria:

* Performance status =\< 3 (Eastern Cooperative Oncology Group \[ECOG\] scale)
* Total serum bilirubin =\< 2 x upper limit of normal (ULN), unless due to Gilbert's syndrome, hemolysis or the underlying leukemia approved by the principal investigator (PI) Alanine aminotransferase (ALT) =\< 1.5 x ULN, unless due to the underlying leukemia approved by the PI Aspartate aminotransferase (AST) =\< 1.5 x ULN unless due to the underlying leukemia approved by the PI Creatinine clearance \>= 30 mL/min Serum lipase =\< 1.5 x ULN Amylase =\< 1.5 x ULN Ability to swallow Signed informed consent

Exclusion Criteria:

Active serious infection not controlled by oral or intravenous antibiotics (e.g. persistent fever or lack of improvement despite antimicrobial treatment) History of acute pancreatitis within 6 months of study or history of chronic pancreatitis Uncontrolled hypertriglyceridemia (triglycerides \> 450 mg/dL) Active secondary malignancy that in the investigator's opinion will shorten survival to less than 1 year Active grade III-V cardiac failure as defined by the New York Heart Association criteria

Clinically significant, uncontrolled, or active cardiovascular disease, specifically including, but not restricted to:

Myocardial infarction (MI), stroke, revascularization, unstable angina or transient ischemic attack within 6 months Left ventricular ejection fraction (LVEF) less than lower limit of normal per local institutional standards prior to enrollment Diagnosed or suspected congenital long QT syndrome Clinically significant atrial or ventricular arrhythmias (such as uncontrolled, clinically significant atrial fibrillation, ventricular tachycardia, ventricular fibrillation, or torsades de pointes) as determined by the treating physician Prolonged corrected QT (QTc) interval on pre-entry electrocardiogram (\> 480 msec) unless corrected after electrolyte replacement History of venous thromboembolism including deep venous thrombosis or pulmonary embolism within the past 3 months, excluding line-associated deep venous thrombosis (DVT) of the upper extremity Uncontrolled hypertension (diastolic blood pressure \> 100 mmHg; systolic \> 150 mmHg)
