FDA expanded the approved use of Stivarga (regorafinib) to include treatment of patients with hepatocellular carcinoma (HCC or liver cancer) who have been previously treated with the drug sorafenib. This is the first FDA-approved treatment for a liver cancer in almost a decade. Stivarga is a kinase inhibitor that works by blocking several enzymes that promote cancer growth, including enzymes in the vascular endothelial growth factor pathway. Stivarga is also approved to treat colorectal cancer and gastrointestinal stromal tumors that are no longer responding to previous treatments.
