To access the anti-tumor efficacy, safety and tolerability of Sunvozertinib combined with chemotherapy in patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) sensitizing mutations who have progressed following standard TKI therapy.

This study is a single arm study to access the anti-tumor efficacy, safety and tolerability of Sunvozertinib combined with chemotherapy in patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) sensitizing mutations who have progressed following standard TKI therapy.

Inclusion Criteria:

1. To provide a signed and dated, written informed consent.
2. 80≥Age ≥ 18 years old
3. Histologically or cytologically confirmed non-squamous NSCLC with documented EGFR mutations from a local laboratory
4. EGFR-sensitive mutations including exon 19 deletion and exon 21 L858R mutated, and exon 20 T790M mutated.
5. Predicted life expectancy ≥ 12 weeks
6. EGFR-TKI resistance or intolerant to standard EGFR TKIs therapy.
7. No previous systemic chemotherapy for advanced or metastatic disease.
8. Adequate organ system function:
9. Patient must have measurable disease according to RECIST 1.1.
10. Patients with stable or pre-treated brain metastasis (BM) can be enrolled

Exclusion Criteria:

1. Spinal cord compression or meningeal metastasis
2. A history of malignant tumors within 2 years.
3. With known resistant mutations that have approved target therapy
4. Recover from AEs caused by previous treatment
5. A history of stroke or intracranial hemorrhage within 6 months prior to initial dosing.
6. Any severe or poorly controlled systemic disease per investigator's judgment active infections, including but not limited to hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency (HIV)
