- Prior exposure to any anti-PD-1, anti-PD-L1, anti-CTLA-4 antibodies, or any other antibody or drug therapy against T cell co-stimulation or checkpoint pathways;
- Patients have had other malignancies within the past 5 years or at the same time (except for cured basal cell carcinoma of the skin and carcinoma in situ of the cervix);
- There are obvious clinical bleeding symptoms or obvious bleeding tendency, hemoptysis, etc. within 3 months before treatment. or venous/venous thrombotic event treatment within the preceding 6 months, such as cerebrovascular accident (including transient ischemic attack, intracerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism; or requiring long-term anticoagulation with warfarin or heparin, or requiring long-term antiplatelet therapy (aspirin≥ 300 mg/day or clopidogrel ≥75 mg/day);
