9. Kidney function (based on the clinical trial center's normal values):

Serum creatinine ≤1.5 × ULN, or calculated creatinine clearance (CrCl) by the Cockcroft-Gault formula ≥60 mL/min, or measured 24-hour urine CrCl ≥60 mL/min.

10. Heart function:

11. All subjects must have locally advanced or metastatic non-small cell lung cancer (NSCLC) confirmed by histology or cytology.

12. Must have at least one EGFR-sensitive mutation: exon 19 deletion, L858R mutation in exon 21, T790M mutation in exon 20, G719X mutation in exon 18, S768I mutation in exon 20, or L871Q mutation in exon 21 (inclusion of patients with exon 20 insertion mutation is allowed).

13. Must have received approved first/second/third-generation EGFR-TKI treatment in the past and experienced radiological progression during EGFR-TKI treatment. The patient is allowed to have received other systemic treatments such as chemotherapy and anti-angiogenic agents, regardless of the sequence with EGFR-TKI treatment.

14. Must provide a tumor tissue sample that meets the central laboratory's testing requirements and has MET (IHC) expression of 1+, 2+, or 3+ as determined by the central laboratory.

15. Must agree to provide tumor tissue or blood samples collected during or after previous EGFR-TKI treatment-induced radiological progression for EGFR T790M detection or provide the results of EGFR T790M detection in the tumor tissue sample.

16. Must provide the most recent tumor tissue sample for PD-L1 expression testing, which will be used to stratify subjects for randomization.

17. At least one measurable lesion according to RECIST 1.1 criteria.

Exclusion Criteria

15. Women who are pregnant or breastfeeding or women/men who are planning to have children.

16. Subjects who are estimated to have insufficient patient compliance to participate in this clinical study or who, in the opinion of the investigator, have other factors that make them inappropriate for participation in this study.

Subjects who have been treated for brain metastases may be considered for participation in this study provided that the disease has been stable for at least 3 months, no disease progression has occurred as determined by imaging within 4 weeks prior to the first dose of study treatment, all neurological symptoms have returned to baseline levels, there is no evidence of new or expanding brain metastases, and treatment with radiation, surgery, or steroids has been discontinued at least 28 days prior to the first dose of study treatment .

19. Other malignancies (except non-melanoma skin cancer, cervical carcinoma in situ or other tumors that have been effectively treated and are considered cured) within 5 years prior to signing the informed consent form.

20. Known hypersensitivity or delayed allergic reactions to certain components of RC108 for injection, vomitinib or similar drugs, in addition to non-enrollment in Cohort 2 and Cohort 4 for hypersensitivity or delayed allergic reactions to certain components of treprolizumab or similar drugs

21. Have received drugs targeting the HGF and/or MET pathways prior to study administration.

22. Prior use of PD-1/L1 inhibitors is inadmissible to Cohort 2 and Cohort 4.

23. Chemotherapy, radiotherapy, immunotherapy and targeted therapy received prior to the start of study dosing less than 4 weeks or less than 5 half-lives (whichever is shorter) from the first dose of this study.
