4. Heart: left ventricular ejection fraction (LVEF)≥50% as assessed by echocardiography (ECHO) or multigated acquisition (MUGA).

5. Thyroid function: thyroid stimulating hormone (TSH) ≤ ULN; if abnormal, T3 and T4 levels should be investigated, and normal T3 and T4 levels can be included.

10. Female subjects of childbearing potential must have a negative serum pregnancy test within 7 days before the first dose and must be willing to use very efficient barrier methods of contraception for the course of the study through 6 months after the last dose of study treatment.

11. The patient can swallow pills.

Exclusion Criteria:

2. Other clinical trials of drugs were used in the first four weeks before the first dose.

3. Subjects with severe allergic reactions to other monoclonal antibodies.

4. Received other anti-tumor treatments within 28 days before the first dose.

5. A heart condition or disease that is not well controlled.

6. Subjects with treatment history of anti-angiogenesis drugs, or immunotherapy (previous use of anti-PD-1/PD-L1 antibodies was allowed) or eribulin.

14. Patients who are allergic to or contraindicated to the experimental drugs.

15. Concurrent medical conditions that, in the judgment of the investigator, would jeopardize the subject's safety, could confound the study results, or affect the subject's completion of this study.
