2. Cytologically or histologically confirmed diagnosis of Stage IV NSCLC as defined by the American Joint Committee on Cancer Staging Criteria for Lung Cancer (AJCC 8th edition).

3. Phase Ib dose escalation Cohort: Previous genetic tests confirmed EGFR-sensitive mutations, and received one or two generations of EGFR TKI treatment. After drug resistance, it was confirmed to be positive for EGFR T790M mutation by biopsy or free DNA test.

•Phase Ib expansion Cohort: Eligible for first-line treatment with erlotinib based on documented evidence of tumor harboring an activating EGFR mutation [exon 19 deletion or exon 21 (L858R) substitution mutation].

4. At least one Measurable lesion.

5. ECOG Performance status (PS) score, 0-1 level.

6. Adequate hematologic function, as defined by: Absolute neutrophil count (ANC) ≥1.5×109/L; hemoglobin concentration ≥90g/L; and platelet count ≥80×109/L.

• Adequate renal function, as defined by: serum creatinine level≤ 1.5 × ULN, or creatinine clearance ≥ 50ml / min.
• 24-hour urine protein quantitation is <1g（24-hour urine protein quantitative test should be performed when urine protein ≥2+ is found during screening visit）.

7. A life expectancy of ≥12 weeks.

8. Aged between 18 and 75 years

9. Subjects (male and female) who have fertility must agree to use reliable contraceptive methods during the trial and in 3 months after the last administration. Female subjects in childbearing age must be negative for blood pregnancy test prior to enrollment.

Exclusion Criteria

1. History of other malignancies, excluding full treated non-melanoma skin cancer, in-situ cancer.

2. Brain metastases unless asymptomatic, stable for at least 4 weeks, and not requiring steroids for at least 2 weeks prior to start of study treatment.

3. Subject with positive HCV-Ab, Anti-HIV or TP-Ab, or positive HBS-Ag with copies of HBV DNA > ULN.

4. Interstitial lung disease

5. Evidence of major coagulopathy or other obvious bleeding tendency，which， in the Investigator's opinion, makes it undesirable for the patient to participate in the trial

6. Any of the following major cardiovascular disease： myocardial infarction or received coronary artery bypass graft within 6 months before the start of the study treatment uncontrolled congestive heart failure unstable angina within 6 months before the start of the study treatment any clinically important abnormalities in rhythm （sustained ventricular tachycardia, second degree heart block and third degree heart block）

7. Uncontrolled diabetes

8. Uncontrolled hypertension (blood pressures: systolic≥140 mmHg and/or diastolic ≥90 mmHg)

9. Uncontrolled third space effusion (pleural effusion and pericardial effusion need to be drained or increased rapidly after drained in three days) .

10. Evidence of active tuberculosis

11. Prior treatment with third generation EGFR-TKIs

12. Previously administrated with anti-angiogenic drugs.

13. Has received systematic anti-tumor therapy such as chemotherapy, targeted therapy, immunotherapy, endocrine therapy, etc. within 4 weeks or 5 half-lives of the drug (whichever is shorter) before the first dose of investigational drug.

14. Has received any biologics that targeted the immune system, such as TNF antagonist, anakinra, rituximab, abatacept and tocilizumab, etc. within 4 weeks before the first dose of investigational drug.

15. Has received Chinese medicine with anti-cancer indications or immunomodulatory drugs （including thymosin，interferon，interleukin，except for the use of treatment for leural effusion）within 2 weeks before the first dose of investigational drug.

16. Has received attenuated live vaccine with 12 weeks before the first dose of investigational drug or would receive attenuated live vaccine during the study (except of COVID-19 vaccines).

17. Has received any other investigational drugs within 4 weeks before the first dose of investigational drug

18. Has participated in a clinical study of a non-approved experimental agent within 4 weeks before the first dose of drug.

19. Has undergone major surgery within 4 weeks before screening visit (not including needle biopsy, video-assisted thoracic surgery, mediastinoscopy)，or would undergo planned surgery during the study.

• Has a nonhealing wound, serious ulcer, or unrecovered bone fracture.

20. Has a known serious allergy reaction to EGFR-TKIs or anti-angiogenic drugs.
