A Study of Vebreltinib and Platinum-Containing Double Agents in Subjects With MET-Positive

Recruiting now · Phase 3

Conditions studied: Non-Small Cell Lung Cancer

In brief

This study is an open-label, randomized, controlled, multicenter Phase IIIb clinical study, aiming to evaluate the efficacy, safety, and tolerability of Vebreltinib Enteric Capsule combined with platinum-based doublet chemotherapy compared with platinum-based doublet chemotherapy in treating subjects with locally advanced or metastatic non-squamous NSCLC who have not received previous systemic treatment and MET-positive. The target population of this study is subjects with histologically confirmed locally advanced or metastatic non-squamous NSCLC who have not received previous systemic anti-tumor treatment and MET-positive( MET Amplification or Overexpression). This study adopts an enrichment design. The enriched population is those with MET GCN ≥ 6, and the overall population is those with MET GCN ≥ 4. This study consists of two parts: the lead-in period (Part 1) and the randomized controlled period (Part 2). Both the lead-in period (Part 1) and the randomized controlled period (Part 2) will include a screening period (from Day -28 to Day -1), a treatment period (until the termination of treatment), and a follow-up period (including safety follow-up and survival follow-up).

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• male or female subjects ≥ 18 years of age at the time of signing ICF.
• histologically or cytologically confirmed diagnosis of non-radical, locally advanced (Stage IIIB and IIIC) or metastatic (Stage IV) non-squamous cell type NSCLC (refer to the American Joint Committee on Cancer [AJCC] Lung Cancer Stages, 8th edition for lung cancer staging criteria).
• Part 1 (introductory stage)Subjects with MET-positive (MET amplification or MET overexpression) tumors will be enrolled. MET amplification is defined as the presence of MET amplification confirmed by second-generation sequencing (NGS) or fluorescence in situ hybridization (FISH) with a mean MET GCN ≥ 4 cells/cell or MET/CEP7 ≥ 2. MET overexpression is defined as c-Met showing strong positive (3+) staining in ≥50% of tumor cells as determined by immunohistochemistry (IHC) (central laboratory results). And subjects are required to provide sufficient tumor tissue (archived or fresh samples) for retrospective analysis in the central laboratory (see Laboratory Manual) to support the development of concomitant diagnostic reagents required for the marketing of Vebreltinib. Part 2 (Randomized Control Phase) MET amplification is defined as subjects' tumor tissue (archived or fresh samples) with an average MET GCN ≥ 4 cells/cell or MET/CEP7 ≥ 2 as confirmed by fluorescence in situ hybridization (FISH) in the central laboratory, and subjects will be required to provide sufficient tumor tissue (archived or fresh samples) for retrospective assay analysis by a central laboratory (see Laboratory Manual). Laboratory Manual) to support the development of concomitant diagnostic reagents required for the marketing of Vebreltinib.

Additionally, if the subject has already undergone testing for BRAF V600E mutation, NTRK fusion, RET fusion, or ERBB2 (HER-2) mutation, the results must be negative.
• Part 2 (Randomized Controlled Period): Documented evidence confirms that the tumor tissue specimen tested negative for sensitive EGFR mutations (including exon 19 deletion, exon 21 L858R or L861Q mutations, exon 18 G719X mutations, exon 20 S768I/T790M mutations, or exon 20 insertion mutations), ALK fusion-negative, ROS1 fusion-negative, and MET exon 14 skipping mutation-negative. Additionally, if the subject has already undergone testing for BRAF V600E mutation, KRAS mutation, NTRK fusion, RET fusion, or ERBB2 (HER-2) mutation, the results must be negative.
