Exclusion Criteria

• •Subjects will not be admitted to the study if they have any of the following conditions:
• •have received any anti-tumor therapy in the past, including radiotherapy, chemotherapy, immunotherapy and traditional Chinese medicine anti-tumor therapy (except the treatment of malignant tumors with radical treatment and no recurrence and metastasis for more than 5 years);
• •Subjects with non-squamous cell histological types of NSCLC with EGFR mutation positive or ALK positive. Non-squamous cell carcinoma subjects must undergo EGFR gene testing and ALK gene and/or immunohistochemical testing;
• •Patients with distant metastases (including M1a, M1b, and M1c);
• •Have any active autoimmune disease or history of autoimmune disease (such as uveitis, enteritis, hepatitis, pituitaritis, vasculitis, myocarditis, nephritis, hyperthyroidism, hypothyroidism (may be included after hormone replacement therapy), tuberculosis); Skin conditions (such as vitiligo, psoriasis, or alopecia) with complete remission of childhood asthma that do not require any intervention in adulthood and do not require systemic treatment may be included, but patients requiring medical intervention with bronchodilators may not be included;
• •Exclude evidence of past or current pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiological pneumonia, drug-induced pneumonia, radiographic evidence of active pneumonia, and severe impairment of lung function;
• •Subjects who have received systemic treatment with corticosteroids (\>10 mg/ day of prednisone or other equivalent hormones) or other immunosuppressants within 2 weeks prior to initial dosing. In the absence of active autoimmune disease, inhaled or topical corticosteroids are permitted, as well as adrenal hormone replacement therapy at doses ≤10 mg/ day of prednisone efficacy;
• •Imaging (CT or MRI) shows that the tumor has invaded large blood vessels or the boundary with blood vessels is blurred; Or imaging (CT or MRI) showing the presence of any pulmonary cavities or necrotic lesions, as determined by the investigator;
• •Patients who had experienced arteriovenous thrombosis events, such as cerebrovascular accident (including temporary ischemic attack, cerebral hemorrhage, cerebral infarction), deep vein thrombosis and pulmonary embolism within 6 months before enrollment;
• •Had clinically significant bleeding symptoms or definite bleeding tendency, such as gastrointestinal bleeding, hemorrhagic gastric ulcer, etc., or were receiving thrombolytic or anticoagulant therapy within 3 months before enrollment;
• •Obvious symptoms of hemoptysis or daily hemoptysis volume of 2.5mL or more within 1 month before enrollment;
• •Patients with hypertension who are not well controlled by antihypertensive drugs (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg); Or grade II or above myocardial ischemia or myocardial infarction, poorly controlled arrhythmias (including QTc interval ≥450ms in men and women)≥470ms); According to NYHA criteria, patients with grade Ⅲ to Ⅳ cardiac insufficiency or left ventricular ejection fraction (LVEF) \< 50% indicated by cardiac color ultrasound;
• •Major operations or serious external injuries of other systems were performed within 2 months before the start of the study;
• •Urine routine indicated urinary protein ≥(++), or 24h urinary protein ≥1g or severe hepatic and renal insufficiency;
• •Uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage;
• •Allergic to the experimental drug;
• •Co-existing with HIV infection or active viral hepatitis;
• •Pregnant or lactating women; The fertile subject is unwilling or unable to take effective contraceptive measures;
• •Those who suffer from neurological diseases or mental diseases and cannot cooperate;
• •Other malignancies developed within 5 or less years before admission, excluding adequately treatable cervical carcinoma in situ, basal cell or squamous cell skin cancer, local prostate cancer after radical surgery, and ductal carcinoma in situ after radical surgery;
• •Other situations deemed unsuitable for inclusion by the researcher.
