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

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).
