Vebreltinib for Neoadjuvant in METex 14 Skipping Mutant Stage IIA-IIIB (N2) Non-small Cell Lung Cancer (NSCLC)

Vebreltinib for Neoadjuvant Treatment in Patients With Stage IIA-IIIB (N2) Non-small Cell Lung Cancer (NSCLC) Harboring METex 14 Skipping Mutant

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Major pathologic response (MPR) rate	MPR rate is defined as the proportion of participants who have achieved major pathologic response (on routine hematoxylin and eosin staining, tumors with no more than 10% viable tumor cells) in all participants.	Up to 30 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pathologic complete response (PCR) rate	PCR rate is defined as the proportion of participants who have achieved pathologic complete response (on routine hematoxylin and eosin staining, no tumor cell can be found in tumor bed or lymph node) in all participants.	Up to 30 months
Treatment-related adverse event (TRAE)	TRAE is defined and classified according to NCI-CTCAE v5.0 in all participants.	Up to 30 months
Event-free survival (EFS)	Event-free survival (EFS) is defined as the length of time (months) from randomization to any of the following events: any progression of disease precluding surgery, progression or recurrence disease based on response evaluation criteria in solid tumors (RECIST) 1.1 after surgery, or death due to any cause. Participants who don't undergo surgery for reason other than progression will be considered to have an event at progression or death. Progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).	up to 60 months
Disease control rate (DCR)	DCR Rate is defined as the proportion of patients who achieve stable disease (SD), partial response (PR), or complete response (CR) among all patients.	up to 30 months
Objective response (ORR) rate	orr is defined as the proportion of patients who achieve partial response (PR), or complete response (CR) among all patients.	up to 30 months
3-year overall survival Rate	OS is defined as the time (months) from enrollment to death of participant due to any cause. In the case of a patient who still survives at the time of analysis, the date of last contact will be taken as the censoring date.	Up to 36 months
Overall survival (OS)	OS is defined as the time (months) from enrollment to death of participant due to any cause. In the case of a patient who still survives at the time of analysis, the date of last contact will be taken as the censoring date.	up to 60 months
