Criteria

Inclusion Criteria:

1. Voluntary participation and signing of informed consent

2. Age ≥ 18 years;

3. the Eastern United States cancer cooperation group (ECoG) score 0-1;

4. Platinum-resistant recurrent ovarian cancer (PROC): the patient was diagnosed with platinum-resistant recurrence for the first time. PROC refers to the disease progression that occurred < 6 months after the last dose of platinum-based chemotherapy. Imaging-based evaluation for the latest recurrence/progression before enrollment was required;

5. Malignant epithelial ovarian cancer, fallopian tube cancer or primary peritoneal cancer confirmed by histology or cytology, including high-grade serous cancer, low-grade serous cancer, endometrioid cancer, clear cell cancer, mucinous cancer, and carcinosarcoma;

6. Biomarker detection and tumor sample collection meet the following standards:

• Patients must provide archived tumor tissue samples (formalin-fixed, paraffin-embedded tumor tissue blocks [preferred], or about 20 unstained tissue sections), except for patients with serous carcinoma, endometrioid carcinoma, clear cell carcinoma and gBRCAm

• If the patient has been tested for BRCA1 / 2 gene in the past, only the corresponding test report needs to be provided

7. Sufficient organ functions, which is defined as:

• neutrophil absolute value (ANC) ≥ 1.5 × 109/L

• platelet count (PLT) ≥ 75 × 10*9/L

• hemoglobin ≥ 9 g / dl

• serum creatinine CR < 1.5 × Upper normal value (ULN)

• total serum bilirubin ≤ 1.5 × Upper normal range (ULN)

• both aspartate aminotransferase and alanine aminotransferase ≤ 3 × ULN

• coagulation function: international normalized ratio (INR) ≤ 1.5; Activated partial prothrombin time (APTT) ≤ 1.5 × ULN

8. Patients must have lesions that can be measured according to RECIST v1.1 standard;

9. Participants were allowed to have previously VEGF / VEGFR inhibitors treatment, but the proportion of these patients would not exceed 20%;

10. Participants were allowed to have previously PARP inhibitors treatment. However, for treatment arm 1 (arm1), the exposure time of PARP inhibitors should ≥ 12 months after first-line chemotherapy or ≥ 6 months after second-line and above chemotherapy;

11. Life expectancy ≥ 3 months;

Exclusion Criteria:

1. The exclusion criteria of bevacizumab were clinically significant cardiovascular and cerebrovascular diseases, history of abdominal fistula or gastrointestinal perforation, acute intestinal obstruction or sub obstruction, and active bleeding;

2. Uncontrolled hypertension (systolic blood pressure > 150 mmHg and/or diastolic blood pressure > 100 mmHg) or clinically significant (active) cardiovascular disease: cerebrovascular accident (CVA) / stroke ≤ 6 months from the treatment of the first clinical study; Myocardial infarction ≤ 6 months from the first clinical study treatment; Unstable angina pectoris; Congestive heart failure (CHF) of grade II or above in the cardiac function classification standard of the New York Heart Association (NYHA); Serious arrhythmias requiring treatment;

3. Previous medical history showed newly discovered thrombotic diseases within 6 months before or during the screening period; Patients with severe wound nonunion, ulcer, or fracture;

4. Major surgery within 30 days before the first administration of study treatment; Patients expected to have invasive surgery during treatment;

5. Patients with other malignant tumors;

6. Patients who have previously received anti-programmed cell death protein-1 (anti-PD-1), anti-programmed death ligand-1 (anti-PD-L1) or anti-PD-L2 drugs, or another drug treatment for T cell inhibitory receptors (e.g., cytotoxic T lymphocyte-associated antigen-4 [CTLA-4], OX-40, CD137 [tumor necrosis factor receptor superfamily member 9 (tnfrsf9)];

7. Active autoimmune diseases requiring systemic treatment in the past 2 years;

8. Any case requiring systemic treatment with corticosteroids (prednisone or equivalent > 10 mg/day) or other immunosuppressive drugs ≤ 14 days before the first administration of the study drug;

9. Known history of human immunodeficiency virus (HIV) infection;

10. Untreated chronic hepatitis B or chronic hepatitis B virus (HBV) carriers (HBV DNA > 500 IU / ml) or active HCV carriers with detectable HCV RNA; Note: inactive hepatitis B surface antigen (HBsAg) carriers and treated and stable hepatitis B patients (HBV DNA < 500 IU / ml) can be included in the group;

11. History of interstitial lung disease, noninfectious pneumonia, or uncontrolled diseases, including pulmonary fibrosis, acute lung disease, etc;

12. Previous heterologous stem cell transplantation or organ transplantation;

13. Peripheral neuropathy ≥ grade 2;

14. Foods or drugs that are expected to use CYP3A4 strong inducers or strong inhibitors within 28 days before the use of the study drug;

15. Participate in another clinical study at the same time, unless it is an observational (non-intervention) clinical study or is in the follow-up period of intervention study;

16. Women of childbearing age who are unwilling or unable to use effective methods for contraception during the whole treatment period of this trial and within 6 months after the last administration of the study drug [women of childbearing age include: any women who have had menarche and have not undergone successful artificial sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), or premenopausal], pregnant or lactating women.

17. Other conditions judged by the researcher that do not meet the enrollment requirements.
