Phase I study of the combination of crizotinib (as a MET inhibitor) and dasatinib (as a c-SRC inhibitor) in patients with advanced cancer.

Background Both MET and c-SRC are important mediators of cancer progression and there is cross talk between the two molecules. Preclinical studies have demonstrated combination of MET and c-SRC inhibitors is effective in multiple cancer types. Methods We analyzed the safety and efficacy of administering a c-SRC inhibitor (dasatinib) in combination with a MET inhibitor (crizotinib) in a two-arm concurrent phase I study.
