Dovitinib Plus Docetaxel in Gastric Cancer

Docetaxel is currently one of standard second-line therapy in patients with gastric cancer. As angiogenesis and FGFR pathway has been suggested to be associated with gastric cancer, dovitinib, dual VEGFR and FGFR inhibitor, may have the potential to improve the outcomes of patients with gastric cancer. Therefore, we investigated the combination regimen of docetaxel and dovitinib.
