Inclusion Criteria:

• (1) Fully understand the purpose of the experiment, the investigator judges that he can abide by the experiment protocol, and voluntarily sign a written informed consent.

  (2) The age at the time of signing the informed consent is ≥18 years old, regardless of gender.

  (3) Patients with non-squamous non-small cell lung cancer (NSCLC) diagnosed by histology/cytology.

  (4) According to the TNM staging of UICC 8th edition, it is determined as ⅢB (not suitable for surgery or radiotherapy)-IV stage NSCLC.

  (5) The patient has EGFR exon 19 deletion (19del) or 21 exon [L858R] mutation confirmed by the central laboratory (only tissue samples are accepted), and it is suitable for first-line treatment of EGFR-TKI.

  (6) Have not received any systemic treatment for non-small cell lung cancer in the past, and have not received any EGFR-TKI drug treatment. If the subject has received adjuvant/neo-adjuvant therapy and then relapses, but the end of adjuvant/neo-adjuvant therapy is more than 6 months after the first dose of this study, the subject can also be included in the group.

  (7) There is at least one measurable lesion based on RECISTv1.1. (8) The ECOG score is 0~1. (9) The functions of major organs and bone marrow are basically normal. It is required that no blood transfusion or hematopoietic stimulating factors have been used within 14 days before screening. The laboratory test results are the results within 7 days before the start of treatment:

  ①Cagulation function INR≤1.5×ULN, aPTT≤1.5×ULN (if the subject is receiving anticoagulant therapy Treatment, as long as the aPTT is within the expected treatment range of anticoagulant drugs);

  ②The subject's liver and kidney function meets the following conditions: total bilirubin≤1.5×ULN, ALT and AST≤2.5×ULN, if the liver is invaded by tumor, AST and ALT≤5×ULN; endogenous creatinine clearance ≥60mL/min (Cockcroft-Gault formula); urine protein is 0 or 1, or urine protein quantitative <1g/24h ；

  ③The blood routine meets: neutrophil count ≥1.5×109/L, platelet ≥100×109/L, hemoglobin ≥9g/dL.

  (10) Adverse reactions caused by previous local treatments, surgery or other anti-cancer treatments have recovered to ≤ CTCAE level 1 (except for hair loss).

  (11) The life expectancy of the patient is> 12 weeks. (12) Take effective contraceptive measures throughout the study period until 12 weeks after the last medication.

     • Severe infections that are active or uncontrolled, such as nosocomial infections, bacteremia, severe lung infections, etc.; ④Patients with severe immunodeficiency (except those related to corticosteroid use), including those who are known to be HIV-positive; ⑤ Liver damage: Child-Pugh grade B (or worse) with severe liver cirrhosis; liver cirrhosis with a history of hepatic encephalopathy; clinically significant ascites caused by liver cirrhosis, which requires diuretic and/or puncture treatment; yes History of hepatorenal syndrome.

10. Evidence of major coagulopathy or other obvious bleeding tendency:

    • Bleeding incidents caused by esophageal and/or gastric varices occurred within 6 months before the start of the study treatment;

      • Hemoptysis occurred within 1 month before the start of study treatment (>2.5 mL bright red blood each time);
