Exclusion criteria
Exclusion criteria: Phase Ib and II: 1. Patients with active autoimmune diseases or a history of autoimmune diseases, including, but not limited to: hepatitis, interstitial pneumonia, uveitis, inflammatory bowel disease, hypophysitis, vasculitis, nephritis, hyperthyroidism, hypothyroidism (can be included after effective hormone replacement therapy); patients with vitiligo or asthma that has completely resolved in childhood, who do not need any intervention as an adult and require bronchodilators for medical intervention can be included; 2. Subjects who require systemic treatment with corticosteroids (>10mg/day prednisone effective dose) or other immunosuppressants within 14 days before the administration of the investigational drug. Inhaled or topical steroids and adrenal hormone replacement with a dose of >10mg/day prednisone effective dose are allowed in the absence of active autoimmune diseases; 3. Known allergy to antibody drugs, or allergy to the investigational drug and/or its excipients. 4. Subjects who had coughing up blood or hemoptysis within 28 days before enrollment (defined as coughing up =1 teaspoon of fresh blood or small blood clots or only coughing up blood without sputum), but blood in sputum is not excluded; 5. Imaging within 28 days before enrollment showed that the tumor surrounded important blood vessels or had the risk of invading blood vessels, and the investigator determined that entering the study would cause bleeding risk; 6. Toxicity related to previous anti-tumor treatment has not recovered to = CTCAE grade 1, excluding alopecia and neurotoxicity; 7. Suffering from other malignant tumors in the past 5 years (excluding basal cell carcinoma of the skin and cervical carcinoma in situ that have been effectively controlled); 8. Central nervous system (CNS) metastasis or malignant tumor-related epilepsy that requires clinical intervention. Patients with CNS metastases that have been treated and are stable for =3 months (no need for glucocorticoids or anti-epileptic drugs), as well as CNS metastases without brain metastasis-related symptoms, can participate in this study; 9. Patients who have received chemotherapy, molecular targeted therapy, immunotherapy, biological therapy, hormone therapy within 4 weeks before the first dose, or received anti-tumor Chinese medicine treatment within 2 weeks (subject to the indications in the Chinese medicine instructions, see Appendix 5 for details) and other systemic anti-tumor treatments; except for the following items: nitrosourea or mitomycin C within 6 weeks before the first use of the study drug; oral fluorouracil and small molecule targeted drugs within 2 weeks before the first use of the study drug or within 5 half-lives of the drug (whichever is longer); 10. Vaccinated with live vaccines within 4 weeks before the start of study treatment; 11. Received radical radiotherapy (including more than 25% bone marrow radiotherapy) within 4 weeks before the first dose, or received local palliative radiotherapy for bone metastases within 2 weeks; 12. Clinically uncontrollable serous effusion (such as pleural effusion that cannot be controlled by drainage or other methods); 13. Past or recent history of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonia, drug-related pneumonia, severe lung function impairment, etc. 14.
