Inhibition of MET May Help Overcome TKI Drug Resistance in Lung Cancer | Lung Cancer Dispatch |

Tyrosine kinase inhibitors (TKIs) that block EGFR are effective treatments for many cases of advanced non-small cell lung cancer (NSCLC), but are limited by the fact that patients will eventually develop resistance against them. Overexpression of the MET gene may contribute to EGFR-TKI resistance, suggesting that combined inhibition of both EGFR and MET may prevent or overcome this drug resistance. Several MET inhibitors have been developed, including cabozantinib (Cometriq), tivantinib, onartuzumab, and ficlatuzumab, and ongoing trials are investigating the safety and effectiveness of combining them with an EGFR-TKI like erlotinib (Tarceva) or gefitinib (Iressa).
