Title: Progress in Discovery of KIF5B-RET Kinase Inhibitors for the Treatment of Non-Small-Cell Lung Cancer.

Authors: Song M.

Abstract: A new chimeric fusion transcript of KIF5B (the kinesin family 5B gene) and the RET (Rearranged during Transcription) oncogene, KIF5B-RET, was found in 1-2% of lung adenocarcinomas (LADCs) in late 2011. Several related clinical trials for non-small-cell lung cancer (NSCLC) with KIF5B-RET rearrangements using existing RET inhibitors, such as lenvatinib, vandetanib, sunitinib, ponatinib, cabozantinib, and AUY922, have been swiftly initiated by the discovery of the KIF5B-RET fusion gene. Anti-RET activity and the status of clinical development of these known RET tyrosine kinase inhibitors (TKIs) for KIF5B-RET fusion-positive NSCLC are discussed. A kinase inhibitor that can target a driver mutation specifically may lead to a superior clinical benefit compared with broad-spectrum kinase inhibitors. In this regard, an analysis of the structure of RET kinase and its complex with known RET inhibitors are also briefly discussed.
