Exclusion Criteria

• 1.Patients with EGFR 19del mutation , ALK or ROS1 gene fusions.

2. Patients with symptomatic, neurologically unstable central nervous system (CNS) metastases, or CNS diseases that require increased steroid doses to control.

3. Presence or history of a malignant disease other than NSCLC that has been diagnosed and/or required therapy within the past 3 years. Exceptions to this exclusion include: completely resected basal cell and squamous cell skin cancers, and completely resected carcinoma in situ of any type.

4.Previous treatment history meets one of the following criteria: 1)prior treated with systemic treatment. 2)The last administration of other anti-tumor drugs was less than 14 days or 5 half-life period before the initiation of study agents. 3)Received traditional Chinese medicine with anti-tumor indications within 1 week prior to initiation of treatment, 4)Thoracic radiotherapy to lung fields (including whole brain radiotherapy) ≤4 weeks prior to initiation of study treatment , for all other sites (except lung and whole brain) ≤2 weeks prior to initiation of study treatment. 5)Received major surgery within the past 4 weeks, or received resection of brain metastatic lesion within 2 weeks, or the side effects of such surgery have not yet been recovered.

5.Previous anti-tumor therapy toxicity have not been recovered to ≤ Grade 1 (NCI-CTCAE 5.0) or baseline, except for alopecia, skin pigmentation and grade 2 peripheral neurotoxicity.

6.Receive a potent inducer and/or potent inhibitor of CYP3A4 within 1 week prior to initiation of study drug or need receive a potent inducer and/or potent inhibitor of CYP3A4 during the study period.

7.Any serious or uncontrolled systemic disease, including, but not limited to, other serious or psychiatric disorders or laboratory abnormalities, in which the investigator determines that the study drug is not suitable for the patient or affects protocol adherence.

8.Cardiac function and disease meet one of the following criterias: QTc > 470 ms, Severe cardiac arrhythmia; Any risk factors that increase the length of the QTc; New York College of Cardiology (NYHA) Heart function grade ≥3. Poorly controlled hypertension.

9.Have a history of interstitial lung disease, drug-induced interstitial lung disease, or radiation pneumonia requiring steroid therapy, or are currently receiving drug therapy or other clinical interventions, or have existing active interstitial lung disease.

10.A history of thromboembolic or venous thromboembolic events (including myocardial infarction, cerebrovascular event or transient ischemic attack, pulmonary embolism, deep vein thrombosis, or any other severe thromboembolic event) in the 6 months prior to the initial study drug administration, Any life-threatening bleeding event (including treatment requiring blood transfusion, surgery or local treatment, and ongoing medication) was judged to have a bleeding tendency.

11.Active gastrointestinal disorders (such as ulcerative lesions, uncontrolled nausea, vomiting, diarrhea, and malabsorption syndrome) or other conditions (such as inability to swallow the investigational agent, or prior major gastrointestinal surgery) may significantly affect the absorption, distribution, metabolism, or excretion of the oral investigational agent.

12.Patients with poorly controlled pleural effusion, peritoneal effusion, or pericardial effusion were judged by the investigators to be unsuitable for inclusion.

13.Any systemic disease that the investigator determines to require treatment .

14.A history of acute or chronic pancreatitis, pancreatic surgery, or risk factors that may increase the risk of developing pancreatitis.

15.Active infection, including but not limited to:infected with hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) (HIV antibody positive), infected with syphilis, active tuberculosis, the presence of active infections (such as pneumonia) requiring systematic anti-infective therapy within 2 weeks before drug administration in the first study.

16.Patients being treated with warfarin or any other anticoagulant, except low-dose warfarin (< 2 mg) for the prevention of central catheter-associated thrombosis;

17.Participants with known hypersensitivity or contraindications to study drug of same class or any excipient of these agents.

19.Patients were currently enrolled in another clinical study or received another clinical study drug within 2 weeks prior to initiation of study treatment.

20. Other circumstances that, in the judgment of the investigator, may affect the conduct of the clinical study and the determination of the results of the study or increase the risks associated with drug administration.
