WebMar 10, 2024 · Tumors harboring de novo MET amplifications (high level, i.e., MET to chromosome 7 centromere (CEP7) ratio ≥ 5) are primarily dependent on the MET signaling pathway for growth [ 41 ]. These amplifications are identified in < 1–5% of NSCLCs and indicate a poor prognosis [ 41 ]. Webpatients (pts) with NSCLC with high-level METamp by LBx in VISION. Exploratory biomarker analyses are presented herein. Methods: Pts had 0–2 prior therapy lines, high-level METamp by LBx (Guar-dant360; MET copy number ≥2.5), and no MET exon 14 skipping or EGFR/ALK alterations. Pts re-ceived tepotinib 500 mg once daily (450 mg active moiety).
