• Patients who participated in clinical trials of other new drugs or medical devices within the first month of randomization and took the study drug or used the study device;

Más betegség

• Allergy to experimental drugs and their excipients;
• Patients with a history of congestive heart failure (NYHA grade III or above), unstable angina or myocardial infarction, cerebrovascular accidents or thromboembolism within the first 6 months of screening;
• Patients with congenital or acquired bleeding disorders or unstable thrombotic diseases requiring anticoagulant therapy;
• Any active infection requiring systemic treatment (oral, intravenous, subcutaneous, intramuscular, etc.) within the first 14 days of randomization;
• Patients who are positive for human immunodeficiency virus antibodies (HIV Ab) or anti Treponema pallidum antibodies (TP Ab) (Treponema pallidum antibodies positive);
• Patients with epilepsy or those taking psychotropic or sedative drugs during screening;
• Patients who have suffered from other malignant tumors within the past 5 years before the first administration (excluding cured carcinoma in situ and basal cell carcinoma of the skin);

Laborértékek

• For any significant clinical and laboratory abnormalities, the researchers believe that they affect the safety evaluators, such as: a. uncontrollable diabetes - fasting blood glucose>250 mg/dL (13.9 mmol/L), b. hypertension and cannot be reduced to the following range after treatment with two or more antihypertensive drugs (systolic blood pressure<160 mmHg, diastolic blood pressure<100 mmHg), c. peripheral neuropathy;
• Individuals with impaired cardiac function (those with ejection fraction<45% detected by echocardiography, congenital ventricular arrhythmia, QTcF>450 ms on electrocardiogram (males), QTcF>470 ms on electrocardiogram (females), or those with arrhythmia requiring treatment at the time of screening);
• Active infection of hepatitis B virus (HBV) or hepatitis C virus (HCV), except for the following patients: a) HBV infection: patients who are positive for hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) and undergo peripheral blood HBV-DNA testing, with the lower limit of HBV-DNA detection value (i.e. the upper limit of normal value in the laboratory of each research center) can be enrolled; If the baseline HBsAg is positive, continuous antiviral treatment is required after enrollment, and HBV-DNA testing should be conducted every 12 weeks and at EOT visits; b) Patients who are positive for HCV serology but negative for HCV-RNA can be included in the study;

Egyéb

• Researchers believe that there are other factors that are not suitable for participating in the experiment.

• Age range of 18-80 years old , gender not limited;
• Patients diagnosed with primary myelofibrosis (PMF) according to WHO criteria (2016 edition) or patients diagnosed with post polycythemia vera myelofibrosis (PPV-MF) or post thrombocytopenia myelofibrosis (PET-MF) according to IWG-MRT criteria;
• Expected survival period greater than 24 weeks;
• ECOG score 0-2 points;
• Splenomegaly: Palpation of the splenic margin reaching or exceeding 5cm below the rib ; Or due to physical reasons (such as obesity), it may not be palpable, but MRI/CT spleen evaluation during screening confirms a volume of >= 450 cm\^3;

• Can understand and voluntarily sign an informed consent form.
