Exclusion Criteria:

1. Patients with symptomatic brain metastasis, cancerous meningitis, spinal cord compression, or diseases of the brain or pia meningeal revealed by imaging CT or MRI examination during screening (patients with brain metastasis who had completed treatment 4 weeks before enrollment and had stable symptoms without progression could be enrolled, but were confirmed to have no symptoms of cerebral hemorrhage by craniocerebral MRI, CT or venography evaluation);

2. The patient is participating in other clinical studies (excluding non-interventional studies) or less than 4 weeks after the completion of treatment in the previous clinical study;

3. has had or is currently co-existing with other malignancies within the past 2 years, except for cured cervical carcinoma in situ, non-melanoma skin cancer, and superficial bladder tumors [Ta (non-invasive tumor), Tis (carcinoma in situ), and T1 (tumor infiltrating basal membrane)];

4. Have an active, known or suspected autoimmune disease, including a history of allogeneic organ transplantation, allogeneic hematopoietic stem cell transplantation, hiv-positive history, or acquired immune deficiency syndrome (AIDS).

5. Randomize patients with any disease requiring systemic treatment with corticosteroids (prednisone >10 mg/ day or equivalent) or other immunosuppressive agents within the first 14 days of treatment.

6. Patients who did not recover to NCI-CTCAE≤1 for adverse reactions related to previous anti-tumor therapy (except hair loss);

7. Suffering from serious cardiovascular diseases: grade ⅱ or above myocardial ischemia or myocardial infarction, poorly controlled arrhythmia;Patients with grade ⅲ ~ ⅳ cardiac insufficiency according to NYHA standard, or left ventricular ejection fraction (LVEF) < 50% as indicated by color doppler echocardiography;

9. A known history of severe hypersensitivity to other monoclonal antibodies;

10. A known history of psychotropic drug abuse, alcoholism or drug abuse;

11. Active hepatitis that cannot be controlled after treatment (HEPATITIS B: HBsAg positive and HBV DNA≥1 x 103 copies /ml;Hepatitis C: HCV RNA positive and abnormal liver function);Co-infection with hepatitis B and c; (5) In the judgment of the researcher, the patient may have other factors that may lead to the termination of the study, such as other serious diseases or serious abnormal laboratory tests, or other factors that may affect the safety of the subjects, or family or social factors that may affect the collection of test data and samples.
