Sorafenib is a kinase inhibitor used to treat unresectable liver carcinoma, advanced renal carcinoma, and differentiated thyroid carcinoma.
Kinases are involved in tumour cell signalling, proliferation, angiogenesis, and apoptosis. Sorafenib inhibits multiple intracellular serine/threonine kinases in the Ras/mitogen-activated protein kinase (MAPK) signal transduction pathway. Intracellular Raf serine/threonine kinase isoforms inhibited by sorafenib include Raf-1 (or C-Raf), wild-type B-Raf, and mutant B-Raf. Sorafenib inhibits cell surface tyrosine kinase receptors such as KIT, FMS-like tyrosine kinase 3 (FLT-3), RET, RET/PTC, vascular endothelial growth factor receptor-1 (VEGFR-1), VEGFR-2, VEGFR-3, and platelet-derived growth factor receptor-β (PDGFR-β). Sorafenib is thought to exhibit a dual mechanism of action: it blocks tumour proliferation and growth by inhibiting the RAF/MEK/extracellular signal-regulated kinase (ERK) pathway on tumour cells, and reduces tumour angiogenesis by inhibiting VEGFR and PDGFR signalling in tumour vasculature.
Sorafenib is indicated for the treatment of unresectable hepatocellular carcinoma and advanced renal cell carcinoma. In the US, it is also indicated for the treatment of patients with locally recurrent or metastatic, progressive, differentiated thyroid carcinoma that is refractory to radioactive iodine treatment.
