Eligibility Criteria

Inclusion

  • ≥ 18 and ≤ 75 years of age. Signed the informed consent form prior to patient entry
  • Histologically or pathologically confirmed non-squamous non-small cell lung cancer(NSCLC) with stage IV /III
  • Patients with EGFR sensitive mutations: 19del and L858R who have not been treated with TKI for the first time, the patients need to provide the test results of the certified detection platform, and the PD-L1 expression based on tissue specimen detection is greater than 50% (PD-L1 detection clone number: SP263).
  • A World Health Organization (WHO)/Eastern Cooperative Oncology Group (ECOG) Performance Status Score (PS) of 0 or 1 at the time of recruitment.
  • Adequate organ and bone marrow function, defined as:
  • Hemoglobin≥9.0 g/dL
  • Absolute neutrophil count ≥1.5 × 109/L
  • Platelet count ≥100 × 109/L
  • Serum bilirubin ≤ 1.5 × upper limit of normal range (ULN). This does not apply to patients diagnosed with Gilbert's syndrome (persistent or recurrent hyperbilirubinemia \[primarily unconjugated bilirubin\] without evidence of hemolysis or liver pathology), which may be allowed after consultation with a physician patients participating in the study.
  • ALT and AST ≤2.5 × ULN
  • Measured creatinine clearance (CL) \>40 mL/min or Cockcroft-Gault calculated CL \>40 mL/min (using actual body weight) Men: Creatinine clearance (mLmin⁄) = body weight (kg) x (140-age) 72 x serum creatinine (mg/dL) Female: creatinine clearance (mLmin⁄) = body weight (kg) x (140-age) 72 x serum creatinine (mg/dL) x 0.85
  • The expected survival time of patients is ≥3 months
  • Weight \> 30 kg
  • Have the ability to sign the informed consent form and comply with the requirements and restrictions listed in the informed consent form (ICF) and this protocol.

Exclusion

  • Patients with grade ≥2 non-infectious pneumonia.
  • History of allogeneic organ transplantation, except corneal transplantation.
  • Active or previously documented autoimmune or inflammatory diseases (including inflammatory bowel disease \[eg, colitis or Crohn's disease\], diverticulitis \[except diverticulosis\], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome \[granulomatous vasculitis, Graves disease, rheumatoid arthritis, hypophysitis, uveitis, etc.\]). Exceptions to this standard include:
  • Vitiligo or alopecia patients
  • Patients with hypothyroidism who are stable on hormone replacement therapy (eg, after Hashimoto's syndrome)
  • Any chronic skin disease that does not require systemic treatment
  • Patients without active disease within the past 5 years may be included in the study, but only after consultation with the study physician
  • Patients with celiac disease that can be controlled with diet alone
  • Uncontrolled concurrent diseases, including but not limited to: persistent or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, uncontrolled arrhythmia, active ILD , Severe chronic gastrointestinal disease with diarrhea, or a psychiatric/social condition that may limit compliance with study requirements, cause a significantly increased risk of AEs, or interfere with the subject's ability to provide written informed consent.
  • History of another primary malignant tumor, except for the following cases;
  • Malignant tumors with low potential risk of recurrence and no known active disease ≥5 years prior to first dose treated with curative intent
  • Adequately treated non-melanoma skin cancer with no evidence of disease or lentigo maligna
  • Adequately treated cervical carcinoma in situ without evidence of disease
  • History of active primary immunodeficiency
  • Active infection, including tuberculosis (clinical assessment, including clinical history, physical examination, radiographic findings, and tuberculosis testing consistent with local clinical practice).
  • Known history of human immunodeficiency virus (HIV) infection; known active syphilis infection.
  • Untreated active hepatitis B
  • Hepatitis B patients who meet the following criteria are eligible for inclusion:
  • \- Hepatitis B virus (HBV) load was below the lower limit of detection in our hospital before the first dose, and received anti-HBV therapy throughout the study period to avoid viral reactivation.
  • Subjects with active hepatitis C (HCV) infection, HCV antibody positive patients only meet the study inclusion criteria when the polymerase chain reaction of HCV RNA is negative.
  • Active brain metastases or spinal cord compression. Prior to study entry, all patients underwent MRI (preferred) or CT examination, preferably brain examination with intravenous contrast.
  • Known allergy or hypersensitivity reaction to any study drug or any study drug excipients
  • Previous exposure to immune-mediated therapy, including but not limited to: anti-PD-1, anti-PD-L1 and anti-programmed death ligand 2 (anti-PD-L2) antibodies, except for therapeutic anti-tumor vaccines .
  • Live attenuated vaccine should be vaccinated within 30 days before the first dose, and live vaccine should not be vaccinated within 30 days after the last dose.
  • Major surgery (as defined by the investigator) within 42 days prior to the first dose.
  • Within 14 days before administration, immunosuppressive drugs are being used or have been used in the past. Exceptions to this standard include:
  • Intranasal, inhaled, topical steroids, or topical steroid injections (eg, intra-articular injections)
  • Systemic corticosteroid therapy not exceeding 10 mg/day of prednisone or its physiologic equivalent
  • Steroids administered as prophylactic for hypersensitivity reactions (eg, prophylactic administration of CT scan)
  • Pregnant or lactating female patients and fertile male or female patients are unwilling to take effective contraceptive measures from screening to 6 months after the last dose.
  • Other researchers think that it is not suitable for inclusion.
  • Mixed cell lung cancer: non-small cell and small cell mixed lung cancer and mixed adenosquamous lung cancer dominated by squamous cell carcinoma.
  • Non-squamous non-small cell lung cancer with hemoptysis (\>50 ml/day); clinically significant hemoptysis or bleeding symptoms occurred within 3 months before enrollment.
  • Patients with brain metastases whose symptoms are not controlled after treatment.
  • Imaging (CT/MRI) shows that the tumor lesion is less than 5 mm away from the large blood vessels, there is a central tumor that invades the local large blood vessels and is less than 2 cm away from the bronchial tree; or there is an obvious lung cavity or necrotic tumor.
  • Arterial/venous thrombotic events that occurred within 12 months before enrollment
  • Patients with any severe and/or uncontrolled disease (hypertension, liver cirrhosis, heart failure, etc.)
  • Major surgical operation or severe traumatic injury, fracture or ulcer occurred within 4 weeks before enrollment
  • Severe weight loss (greater than 10%)
  • Abnormal coagulation function, with bleeding tendency or receiving thrombolytic or anticoagulation therapy
