About

This is a prospective, single-center phase II clinical study aimed at evaluating the efficacy and safety of Vebreltinib in neoadjuvant treatment for patients with resectable stage IIA-IIIB (N2) non-small cell lung cancer (NSCLC) with MET exon 14 skipping mutations. In the study, all eligible subjects who signed the informed consent and met the inclusion and exclusion criteria were treated with Vebreltinib (200 mg bid po) for 8 weeks before surgery. The subjects were evaluated by the investigators and the surgical resection was performed within approximately 2 weeks after the neoadjuvant treatment. The study used RECIST v1.1 for imaging assessment. A CT or enhanced CT scan was conducted within 2 weeks after the end of treatment, and then every 180 days (±14) after surgery until 3 years, and then annually until disease recurrence or death, or the end of the study.

Enrollment: 30 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• The patient shall sign the Informed Consent Form.
• Aged 18 ≥ years.
• Histological or cytological diagnosis of NSCLC by needle biopsy, and evaluated by researchers as stage IIA-IIIB(N2).
• NGS gene testing confirmed MET exon 14 skipping mutations (NGS results from tissue or blood samples certified by CLIA or CAP-approved laboratories);
• Eastern Cooperative Oncology Group (ECOG) performance-status score of 0 or 1.
• According to the MDT evaluation (which should include a thoracic surgeon specializing in tumor surgery), it is considered that the primary NSCLC is potentially completely resectable;
• At least 1 measurable lesion according to RECIST 1.1.
• Patients with good function of other main organs (liver, kidney, blood system, etc.)
• Patients with lung function can tolerate surgery;
• Fertile female patients must voluntarily use effective contraceptives not less than 120 days after chemotherapy or the last dose of toripalimab (whichever is later) during the study period, and urine or serum pregnancy test results within 7 days prior to enrollment are negative.
• Unsterilized male patients must voluntarily use effective contraception during the study period not less than 120 d

Exclusion criteria

• Previously received targeted therapy (including TKI or monoclonal antibodies), immunotherapy, or any investigational drug treatment for NSCLC;
• Pathological confirmation of mixed small cell and non-small cell lung cancer;
• Patients with a malignancy other than NSCLC within five years prior to the start of this trial，except for cured basal cell carcinoma of the skin, early gastrointestinal (GI) carcinoma excised through endoscopy, cervical carcinoma in situ, ductal carcinoma in situ of the breast, papillary thyroid carcinoma, or any cured cancer deemed to have no impact on the survival of the current NSCLC;
• Participants with any unstable systemic disease (including active infection, uncontrolled hypertension), unstable angina pectoris, angina pectoris starting in the last three months, congestive heart failure (>= NYHA) Grade II), myocardial infarction (6 months before admission), severe arrhythmia requiring drug treatment, liver, kidney or metabolic diseases;
• Patients with congenital or acquired immune dysfunction (such as HIV infected individuals);
• Received other major surgical treatments (excluding diagnosis) within 4 weeks prior to the start of the study or expected to undergo major surgical treatments during the study period;
• Participants who are allergic to the test drug or any auxiliary materials; 8.A history of extensive diffuse bilateral interstitial fibrosis in the past or before medication, or a known grade 3 or 4 history of interstitial fibrosis or interstitial lung disease, including pneumonia, allergic pneumonia, interstitial pneumonia, interstitial lung disease, obliterative bronchiolitis, and pulmonary fibrosis, but not including local radiation pneumonia or radiation pulmonary fibrosis history;
• Pregnant or lactating women;
• Any malabsorption;
• Participants suffering from nervous system diseases or mental diseases that cannot cooperate
• Other factors that researchers think it is not suitable for enrollment.
