What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 42 participants in total. It began in 2025-04-08 with a primary completion date of 2027-04.

Brief Summary

The goal of phase Ib study was to evaluate efficacy and tolerability of the combination of vebreltinib and furmonertinib in patients with locally advanced or metastatic non-small cell lung cancer with c-met amplification after failure of EGFR-TKI treatment; to determine the maximum tolerated dose (MTD), and to evaluate the dose-limiting toxicity (DLT) and (recommended Phase 2 dose) RP2D of vebreltinib with furmonertinib. The goal of phase II study was to evaluate efficacy \[overall response rate (ORR), progression-free survival (PFS), and so on\] of vebreltinib and furmonertinib in patients with locally advanced or metastatic non-small cell lung cancer with c-met amplification after failure of EGFR-TKI treatment.

Eligibility Criteria

Inclusion Criteria: 1. Fully aware this study and voluntary to sign the informed consent form, and willing and able to comply with the study procedure. 2. Aged ≥18 years, male or female. 3. Patients with histologically or cytologically confirmed unresectable and non-suitable for radical surgery, or concurrent chemoradiotherapy , locally advanced or metastatic (stage IIIB, IIIC or IV) NSCLC; 4. Documented EGFR sensitive mutations (exon 19 deletion or exon 21 L858R mutation). 5. Disease progression after prior EGFR-TKI therapy. Participants must meet both of the following 2 criteria: (1) ≤1 prior chemotherapy regimen allowed besides EGFR-TKI. Combination with anti-angiogenic therapy or PD-1/PD-L1 inhibitors are allowed during EGFR-TKI targeted therapy or chemotherapy. （2） Objective clinical benefit documented during previous EGFR-TKI therapy, defined by either partial or complete radiological response, or durable stable disease should be greater than 6 months after initiation of EGFR-TKI. 6\. After the last line of treatment before enrollment, progression is confirmed, and blood tests confirm c-Met amplification, or re-biopsy and genetic testing confirm c-Met amplification. Any of the following criteria define c-Met amplification. 1. For tumor tissue samples, FISH detection shows GCN ≥5 and/or MET/CEP7 ≥2 (FISH results from local testing institutions/central laboratories are acceptable); 2. Tissue (wax blocks from pleural effusion centrifugation, if quality-controlled) or blood NGS testing results confirm c-Met amplification with CN ≥2.3 (NGS results from local testing institutions/central laboratories are acceptable for both tissue and blood). 7\. ECOG performance status ≤1. 8. According to RECIST v1.1, the patient must have at least one target lesion as assessed by the investigator. 9\. Laboratory test results must meet the following criteria: 1. Absolute neutrophil count ≥1.5×10⁹/L (without the use of growth factors within 7 days prior to the start of treatment); 2. Hemoglobin ≥90 g/L (without blood transfusion or use of growth factors within 7 days prior to the start of treatment); 3. Platelet count ≥75×10⁹/L (without blood transfusion or use of growth factors within 7 days prior to the start of treatment); 4. Serum total bilirubin ≤1.5×upper limit of normal (ULN); 5. Serum alanine aminotransferase and aspartate aminotransferase ≤3×ULN (for patients with liver metastases, both AST and ALT ≤5×ULN); 6. Creatinine clearance (Ccr) ≥60 mL/min. 7. International normalized ratio (INR) ≤1.5×ULN; 8. Asymptomatic serum amylase ≤Grade 2 (NCI-CTCAE v5.0). For patients with Grade 2 serum amylase abnormalities at the start of the study, it must be confirmed that there are no signs and/or symptoms suggestive of pancreatitis or pancreatic injury (e.g., elevated P-amylase, abnormal pancreatic imaging results); 9. Serum lipase ≤1.5×ULN. 10. Men with reproductive potential and women of childbearing potential must agree to use effective contraception from the time of signing the informed consent form until 3 months after the last dose of the study drug. Women of childbearing potential must have a negative serum pregnancy test within ≤7 days prior to the first dose of the study drug. This does not apply to female subjects who have undergone sterilization or are postmenopausal. 11\. Expected survival ≥3 months. Exclusion Criteria: 1. Patients with ALK fusion or ROS1 fusion. 2. Patients with spinal cord compression, leptomeningeal metastasis, or symptomatic brain metastasis that requires an increase in steroid dosage to control central nervous system disease. Patients with symptomatic CNS metastases that have been controlled may be eligible for this trial. 3. Presence of other malignancies (with the exception of any type of carcinoma in situ that has been completely resected, basal cell and squamous cell skin cancers, or other tumors/cancers that have been treated with curative intent and have been disease-free for at least 3 years). 4. A history of anti-tumor treatment that meets any of the following criteria: （1）Received traditional Chinese medicine or patent medicine with anti-tumor indications within 1 week prior to the first dose of the study drug; （2）Underwent radiotherapy targeting the lung fields and whole brain within 4 weeks prior to the first dose of the study drug, or received radiotherapy targeting other areas (excluding the lung fields and whole brain) within 2 weeks prior to the first dose. Palliative radiotherapy for bone metastases to relieve pain or prevent skeletal-related events is excluded; （3）Underwent major surgery within 4 weeks, or has not recovered from the adverse effects of these surgeries. Thoracoscopic biopsy and mediastinoscopy are not considered major surgeries, and patients may be enrolled ≥1 week after the procedure 5.
