* If it is safety and tolerant in Non-small cell lung cancer patients with MET exon 14 mutation

Participants will

1. be given PLB1001 200mg BID,oral.
2. be received hematology and urine and ECG examinations every 14 days (First 3 months) or every 28 days (After 3 months)
3. be received Image examination every 8 weeks(First year) or every 12 weeks(After one year)


Eligibility criteria: Inclusion Criteria:

2. Male or female aged 18 years and above;
3. patients with histologically or cytologically confirmed locally advanced or metastatic non-small cell lung cancer (including sarcomatoid carcinoma of the lung, according to the AJCC 8th edition of lung cancer staging, Stage IIIB - Stage IV) (non-site pathology reports are acceptable);Patients have not received any prior systemic antineoplastic drug therapy for advanced diseaseor disease progression or toxicity intolerance after prior systemic therapy (≤3 lines);
4. The presence of MET exon 14 jump mutation was confirmed by the NGS test in the central laboratory, and the 'Combined Human 9 Gene Mutation Detection Kit (Reversible End Termination Sequencing)' produced by Guangzhou Burning Stone Medical Laboratory Ltd. will be used for the testing and analysis of the samples in the central laboratory. Patients are required to provide sufficient blood samples for retrospective analysis by the central laboratory ('Human Circulating Tumour DNA Multi-Gene Mutation Test Kit (Reversible End Termination Sequencing Method)' manufactured by Guangzhou Burnstone Medical Laboratory Co.
