Updates: MET Targeted Therapy for EXON 14 Mutations in Lung Cancer

Sep 11, 2023
Researchers discuss MET gene alterations in lung cancer, focusing on targetable changes like exon 14 skipping mutations and fusions. Capmatinib and Crizotinib show promise as treatments, but drug resistance remains a challenge. Various MET tyrosine kinase inhibitors are in development or under evaluation for potential combination therapies.

Met Gene Alterations in Lung Cancer

Alterations in the Met gene, including genomic amplifications, Exxon 14 skipping mutations, and fusion, have been identified as targetable oncogenic changes leading to non-small cell lung cancer (NSCLC). Capmetinib and Chrystinib have shown effectiveness as first-line treatments for patients with NSCLC carrying Met Exxon 14 skipping mutations and Met fusions, respectively. However, primary and secondary acquired drug resistance remains a major challenge after the introduction of tyrosine kinase inhibitors, necessitating the development of structurally different met tyrosine kinase inhibitors (TKIs) to overcome resistance and improve clinical outcomes.
