Tivantinib (ARQ197; byArqule, Inc.) is an experimentalsmall molecule anti-cancer drug. It is abisindolylmaleimide that binds to the dephosphorylatedMET kinasein vitro. (MET is agrowth factor receptor.) Tivantinib is being tested clinically as a highly selectiveMET inhibitor.^[1] However, the mechanism of action of tivantinib is still unclear.^{[citation needed]}

Tivantinib displays cytotoxic activity via molecular mechanisms that are independent from its ability to bind MET, notablytubulin binding, which likely underlies tivantinib cytotoxicity.^[2]

Possible applications includenon-small-cell lung carcinoma,hepatocellular carcinoma, andoesophageal cancer.^[3]

In 2017, it was announced that a phase IIIclinical trial for advancedhepatocellular carcinoma had failed to meet the primary endpoint.^[4]^[5]
