9. Voluntarily signed written informed consent form, willing and able to comply with scheduled visits and other requirements of the study.

Exclusion Criteria:

1. Should receive subsequent adjuvant therapy (such as radiotherapy, chemotherapy, immunotherapy)

2. Received major surgery (such as craniotomy, thoracotomy or laparotomy) within 4 weeks of the first dose of study drugs or open wound, ulcer or fracture.

3. Received any anti-tumor therapy (chemotherapy, targeted therapy, tumor immunotherapy or arterial embolization) or radiotherapy within 4 weeks of the first dose of study treatment.

4. Prior therapy with anti-PD-1,anti-PD-L1,anti-CTLA4 antibody.

5. Currently participating in interventional clinical research treatment, or receiving other research medications within 4 weeks prior to the first dose or used research equipment

6. Received any investigational agent within 4 weeks of the first dose of study treatment.

7. Received radiotherapy within 4 weeks of the first dose of study treatment. Received systemic treatment with high-dose corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive drugs within 4 weeks of first dose.
