 Despite recent advances, glioblastoma multiforme GBM remains an incurable malignancy with a short expected survival. c-MET signalling promotes invasive growth and has been described in various cancers. INC280 is a highly potent and selective c-MET inhibitor which also penetrates the blood-brain barrier. In this open-label, multicenter Phase 1b study, investigators determined the optimal dose of the INC280bevacizumab combination to administer to patients. Enrollment has now expanded in order to treat 3 cohorts of GBM patients: those who progressed after first-line standard therapy, those who progressed after second-line therapy with INC280bevacizumab, and those with unresectable GBM.
