8. Uncontrolled severe concurrent infection resulting in disability;
9. Proteinuria ≥ 2 + (1.0 g/24 h);
10. Evidence or history of bleeding tendency within 2 months prior to enrollment, regardless of seriousness;
11. Arterial/venous thromboembolic events, such as cerebrovascular accidents (including transient ischemic attack), within 12 months before the first treatment;
12. Acute myocardial infarction, acute coronary syndrome or CABG within 6 months before the first treatment;

19. Subjects who are allergic to the study drug or any of its adjuvant preparations;
20. Electrolyte abnormalities judged clinically significant by the investigator;
21. Known human immunodeficiency virus (HIV) infection. Known history of clinically significant liver disease, including viral hepatitis [known hepatitis B virus (HBV) carriers must have excluded active HBV infection, ie, positive HBV DNA (> 1 × 104 copies/mL or > 2000 IU/mL); known hepatitis C virus (HCV) infection and positive HCV RNA (> 1 × 103 copies/mL);

24. with brain metastases, or with severe malignant pleural effusion and ascites;
25. Any other diseases, clinically significant metabolic abnormalities, physical examination abnormalities or laboratory abnormalities, according to the investigator 's judgment, there is reason to suspect that the patient has a disease or condition that is not suitable for the use of the study drug (such as having seizures and requiring treatment), or will affect the interpretation of the study results, or put the patient at high risk;
26. Patients who are considered unsuitable for inclusion in this study by the investigator.
