Golvatinib

Golvatinib (also known as E7050) is a highly potent, small molecule ATP-competitive inhibitor of the c-Met receptor tyrosine kinase and multiple members of the Eph receptor family. c-Met and VEGFR-2 play important roles in tumor cell growth, migration and angiogenesis. Golvatinib (E7050) inhibits the activities of both c-Met and VEGFR-2, which may inhibit tumor cell growth and survival of tumor cells that overexpress these receptor tyrosine kinases. In vitro, Golvatinib (E7050) circumvented resistance to all of the reversible, irreversible, and mutant-selective EGFR-TKIs induced by exogenous and/or endogenous HGF in EGFR mutant lung cancer cell lines, by blocking the Met/Gab1/PI3K/Akt pathway. Golvatinib (E7050) plus gefitinib resulted in marked regression of tumor growth associated with inhibition of Akt phosphorylation in cancer cells in the in vivo model. Golvatinib is currently under evaluation in a phase I clinical trial, it may overcome HGF-induced resistance to gefitinib and next-generation EGFR-TKIs.
