   • If no lesion is assessed prior to chemotherapy, CA125 should be alleviated to the ULN during treatment and maintained at <1xULN for 7 days prior to the first treatment.

Exclusion Criteria:

1. Prior malignancy unless curatively treated and disease-free for > 5 years prior to study entry. Prior adequately treated non-melanoma skin cancer, in situ cancer of the cervix or breast cancer without recurrence over 3 years allowed.
2. Untreated and/or uncontrolled brain metastases.
3. Not able to swallow pills normally, or have abnormal gastrointestinal function affecting drug absorption as judged by the researcher.
4. Intestinal obstruction within 3 months.
5. The urine protein ≥ ++ and 24-hour urine protein level > 1.0g.
6. Patients with clinical symptoms of cancer ascites, pleural effusion, who need to drainage, or who have undergone ascites drainage within 3 months prior to the first administration;
7. Uncontrolled heart clinical symptoms or diseases, such as :(1) NYHA 2 or more heart failure, (2) Unstable angina pectoris, (3) myocardial infarction within 1 year, (4) Ventricular arrhythmias requiring intervention, (5) QTc>470ms.
8. Abnormal coagulation function (INR > 1.5 or prothrombin time (PT) > ULN+4 seconds), bleeding tendency or receiving thrombolytic therapy are allowed to receive low-dose low-molecular weight heparin or oral aspirin preventive anticoagulant therapy during the study.
9. Significant bleeding symptoms or clear bleeding tendency, such as gastrointestinal bleeding, hemorrhagic gastric ulcer or vasculitis, etc., within the first 3 months of the randomization. If fecal occultation blood is positive at baseline, gastroscopy should be performed if still positive after reexamination.
10. Active ulcers, unhealed wounds or fractures.
11. Uncontrolled hypertension by antihypertensive medication (systolic blood pressure ≥140mmHg or diastolic blood pressure ≥90mmHg).
12. Any bleeding event with grade 2 or higher in CTCAE 5.0 within 4 weeks prior randomization.
13. Active infection or unexplained fever >38.5 degrees during screening or before first treatment.
14. Known to be human immunodeficiency virus positive; Known active hepatitis C virus, or known active hepatitis B virus.
15. Received radiotherapy, chemotherapy, hormone therapy, or molecular targeted therapy, less than 4 weeks after the completion of the last dose or less than 5 drug half-lives before the study for oral molecular targeted drug; Adverse events caused by previous treatment (except hair loss) and not recover to ≤1 degree (CTCAE 5.0).
16. Arteriovenous thrombosis events, such as cerebrovascular accident (including transient ischemic attack, cerebral hemorrhage, cerebral infarction), deep vein thrombosis and pulmonary embolism, etc. occurred within 6 months.
17. History of hereditary or acquired bleeding or coagulation disorders (e.g., hemophilia, coagulopathy, thrombocytopenia, etc.).
