• 7. Significant arterial/venous thrombotic events within 6 months prior to first dose, such as deep vein thrombosis and pulmonary embolism. Superficial vein thrombosis without safety risk judged by the investigator is permitted.
• 8. Cardiac dysfunction or clinically meaningful cardiovascular disease, including: (1)New York Heart Association (NYHA) grade II or higher congestive cardiac failure, unstable angina pectoris, and/or myocardial infarction within the 6 months prior to the first dose of the investigational drug, clinically significant arrhythmia unable to be controlled with medical treatment or left ventricular ejection fraction (LVEF) \< 50% at screening. (2)Primary cardiomyopathies (e.g., dilated cardiomyopathy, hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, restrictive cardiomyopathy, indeterminate cardiomyopathy). (3)Clinically significant history of prolonged QTc interval, or QTcF interval \>470ms for females or \>450 ms for males during the screening period. (4)Coronary heart disease with symptoms requiring medication. (5)Documentation of hypertension treatment with≥3 antihypertensive medications simultaneously within 14 days before the first dose of medication or systolic blood pressure≥140 mmHg and/or diastolic blood pressure≥90 mmHg during the screening period (resting state, measured approximately every 5 minutes, averaged after three consecutive measurements, rounded to the nearest integer). (6)History of hypertensive crisis or hypertensive encephalopathy. (7)Other cardiovascular disease judged by the investigator to be unsuitable for enrolment.
• 9. Active bleeding within 2 months prior to the first dose, or taking anticoagulants, such as warfarin, phenprocoumon (prophylactic low-dose aspirin and low-molecular heparin are permitted) during the screening period, or at high risk of bleeding judged by the investigator during screening period (e.g., esophageal varix associated with bleeding risk, locally active ulcer lesions, positive fecal occult blood that can not exclude gastrointestinal bleeding, intermittent haemoptysis) .
• 10. Presence of significant gastrointestinal abnormalities during the screening period that may interfere with drug intake, transit or absorption (e.g. inability to swallow, chronic diarrhoea, post-small bowel resection or total gastrectomy), according to the investigator's judgment.
• 11. History of gastrointestinal perforation and/or fistula, peptic ulcer disease, intestinal obstruction (including incomplete intestinal obstruction that requires parenteral nutrition), or biliary obstruction within 6 months prior to the first dose.

• 13. For urine protein≥2+ by urinalysis during the screening period, a 24-hour urine protein quantification test should be performed. The subject cannot be enrolled if the quantified urine protein is≥1g/24 h. If the quantified urine protein is \<1 g/24 h, the subject can still be enrolled.
