11. Sign a written informed consent (ICF) voluntarily, and have good compliance with the protocol requirements for visits or planned visits and other relevant research procedures.
Exclusion Criteria:
* Subjects who meet any of the following criteria will not be eligible to participate in this clinical trial:

2. Any NCI CTCAE5.0 immune-related adverse reaction (irAE) grade \>3 that has been permanently discontinued during any previous immunotherapy;
3. Patients with prior primary immunodeficiency and active autoimmune disease;
4. Previous history of organ allotransplantation, allogeneic stem cell transplantation and kidney replacement therapy;
5. Patients with current or past irreversible interstitial lung disease (except those caused by radiotherapy);
6. Combined with 2 or more malignant tumors; (Except for the following cases: malignant tumors that have been cured, such as non-melanoma skin cancer and in situ cervical cancer, bladder cancer, breast cancer, thyroid cancer, etc. that have survived more than 5 years without disease.)
7. Uncontrolled co-morbidity includes, but is not limited to, uncontrolled hypertension (systolic blood pressure ≥160mmHg and/or diastolic blood pressure ≥100mmHg) even after standard treatment, or any unstable cardiovascular and cerebrovascular disease, including transient ischemic attack, cerebrovascular accident, myocardial infarction, and unstable angina pectoral, that has occurred in the 6 months prior to treatment induction; Congestive heart failure rated III or IV by the New York Heart Association (NYHA); Ejection fraction \< 50%; Severe heart rhythm or conduction abnormalities, such as ventricular arrhythmias requiring clinical intervention, degree II-III atrioventricular block, etc. Electrocardiogram results show clinically significant abnormalities, or QTcF≥450ms (if the first examination is abnormal, the interval of at least 5 minutes, retest twice, using the comprehensive result/average value to judge eligibility);
8. Patients with esophageal or gastric varices that require immediate intervention (such as ligation or sclerotherapy) or are considered by the investigator or gastroenterologist or hepatologist to be at high risk of bleeding, have evidence of portal hypertension (including splenomegalysis on imaging), or have a history of varicose bleeding must undergo endoscopic evaluation within 3 months prior to enrollment;
9. Uncontrolled metabolic disorders, such as in patients with diabetes, or other non-malignant organ or systemic disease or cancer secondary reactions that can lead to higher medical risk and/or uncertainty in the evaluation of survival;
10. Hepatic encephalopathy, hepatorenal syndrome or Child-Pugh grade C or more severe cirrhosis, liver failure;
11. Clinically uncontrollable third space effusion, such as pleural fluid and ascites that could not be controlled by drainage or other methods before enrollment;
