5. Suffering from active autoimmune diseases that require systematic treatment within the past two years
6. History of immunodeficiency; Individuals who test positive for HIV antibodies; Currently in long-term use of systemic corticosteroids or other immunosuppressants
7. Subjects who are known to have active pulmonary tuberculosis (TB) and suspected of having TB need to undergo clinical examination to exclude them; Known active syphilis infection
8. Known history of allogeneic organ transplantation and allogeneic hematopoietic stem cell transplantation
9. Previous or current non infectious pneumonia/interstitial lung disease requiring systemic corticosteroid therapy
10. Serious infection occurred within 4 weeks prior to the first administration, including but not limited to comorbidities requiring hospitalization, sepsis, or severe pneumonia; Active infections that have received systemic anti infective therapy within 2 weeks prior to the first administration (excluding antiviral therapy for hepatitis B or C)
11. Current active hepatitis B subjects (HBsAg positive and HBV-DNA exceeding 1000 copies/ml (200IU/ml) or above the detection limit)
12. Tumor invasion or compression of important surrounding organs (such as aorta, heart and pericardium, superior vena cava, trachea, esophagus, etc.) or the risk of developing esophagotracheal fistula or esophageal pleural fistula; Tumor mediastinal lymph node metastasis invading the trachea and main bronchus with the risk of bronchial fistula
13. History of myocarditis, cardiomyopathy, and malignant arrhythmia in the past

15. Any arterial thromboembolic event, NCI CTCAE 5.0 grade 3 or higher venous thromboembolic event, transient ischemic attack, cerebrovascular accident, hypertensive crisis, or hypertensive encephalopathy occurred within 6 months prior to the first administration; Currently, there is hypertension and after treatment with oral antihypertensive drugs, the systolic blood pressure is ≥ 160mmHg or the diastolic blood pressure is ≥ 100mmHg

21. Any past or current diseases, treatments, or laboratory abnormalities that may confuse the research results, affect the participants' full participation in the study, or may not be in the best interests of the participants
22. Local or systemic diseases caused by non malignant tumors, or diseases or symptoms secondary to tumors, which can lead to higher medical risks and/or uncertainty in survival evaluation, such as tumor like leukemia reactions (white blood cell count\>20 × 109/L), cachexia manifestations (such as known weight loss of more than 10% in the first 3 months of screening), etc
