This is a Phase II, open-label, multicenter and multi-cohorts study of PLB1001 administered orally twice daily to locally advanced/metastatic NSCLC patients with c-Met dysregulation.

PLB1001 will be administrated 200mg twice daily. The treatment will be discontinued for the patients who experience disease progression, death, adverse event (AE) leading to discontinuation or withdrawal of consent. A cycle of study treatment will be defined as 28 days of continuous dosing. The study includes 4 cohorts.

• At least one measurable lesion as per RECIST v1.1
• Patients must have recovered from all toxicities related to prior anticancer therapies to grade ≤ 1
• ECOG Performance Status of 0-1.

Exclusion Criteria:
