However, the precise role of these molecules as a new treatment option is still not fully defined. Methods: In an attempt to further evaluate the contributions of c-MET inhibitors to the armamentarium of treatment options for advanced and metastatic NSCLCs, relevant phase II and III studies were retrospectively analyzed in terms of ORR and mPFS (mOS numbers are still not available for current c-MET trials and therefore not considered for statistical purposes). Results: Treatment of advanced and metastatic NSCLC patients harbouring c-MET exon 14 skipping mutations with the novel and highly selective c-MET inhibitors is significantly superior (p Conclusion: The novel and highly selective c-MET inhibitors capmatinib and tepotinib are promising novel treatment options for patients with c-MET-dysregulated NSCLC primarily in the first-line setting, albeit a clear mOS benefit has not yet been established. Since immunotherapy did not appear to be particularly effective in NSCLC patients harbouring c-MET alterations, the vast majority of these patients are treated with immunotherapy plus chemotherapy. C-Met inhibitors appear to be equally effective and thereby sparing patients from the toxic effects of the chemotherapy. The routine testing of c-MET exon 14 skipping mutations should be performed as the GEOMETRY mono-1 data clearly showed higher response rates with capmatinib in treatment-naive than in pretreated patients, indicating that c-MET exon 14 skipping mutations should preferably be molecularly assessed at baseline. C-MET exon 14 skipping mutations are, therefore, clear biomarkers of response to c-MET inhibitors.展开更多
