Tepotinib Plus an EGFR Tyrosine Kinase Inhibitor in Patients With EGFR-Mutant MET-Altered NSCLC: A Case Series

• No targeted treatments are currently approved for patients with EGFR-mutant non–small-cell lung cancer (NSCLC) and MET-mediated resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). • This case series describes real-world outcomes with tepotinib, a selective MET-TKI, in combination with EGFR-TKIs in patients with EGFR-mutant, MET-altered NSCLC and resistance to EGFR-TKIs. • Among the 25 patients included, tepotinib was given in combination with a range of EGFR-TKIs (osimertinib, n = 18; gefitinib, n = 5; dacomitinib, n = 1; afatinib, n = 1) as second (n = 8), third (n = 9), or fourth-or-later (n = 8) line therapy. • Tepotinib plus EGFR-TKIs demonstrated clinical benefit per physician's assessment in 23/25 patients, with a partial response in 15/25 patients. • Tepotinib plus EGFR-TKIs showed favorable tolerability that was consistent with previous observations, with edema reported as the most common tepotinib-related adverse event (14/25 patients). • This case series, including patients with several prior treatment lines, suggest tepotinib plus an EGFR-TKI as a potential chemotherapy-sparing, oral targeted treatment option for patients with EGFR‑mutated, MET-altered NSCLC after progression on EGFR‑TKIs.
