Patients receive tivantinib orally (PO) twice daily (BID) on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection at baseline and periodically during study for c-Met expression, relevant markers (HGF and VEGF), PTEN loss, and PI3K mutation analysis by fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC). Archived tumor tissue samples are also analyzed.
