Sunitinib malate is an oral, multitargeted receptor tyrosine kinase inhibitor of VEGF receptors 1, 2 and 3; PDGF receptors alpha and beta, and other receptor tyrosine kinases implicated in tumor growth, angiogenesis and metastasis. Hepatocellular carcinoma (HCC) is a highly vascular tumor that overexpresses several angiogenic factors; VEGF and PDGF signaling pathways play a key role in HCC. Until recently, treatment options for advanced HCC were limited and conventional therapies have met with poor response rates. Sorafenib provided proof-of-concept for molecularly targeted therapy in advanced HCC and has recently been approved for treatment. However, not all patients can tolerate sorafenib and patients may experience tumor progression; therefore, additional treatment options are warranted. Sunitinib has shown early evidence of anti-tumor activity in Phase II trials in US, European and Asian patients with locally advanced, unresectable and metastatic HCC. A Phase III trial of sunitinib in HCC is ongoing.

The approval of a multitargeted receptor tyrosine kinase inhibitor, sorafenib, with activity against vascular endothelial growth factor receptor-2 and -3, Raf-1 and B-Raf, platelet-derived growth factor receptor-alpha and -beta, and other kinases, has ushered in the era of molecular targeted agents in advanced hepatocellular carcinoma (HCC). Sunitinib malate is an oral, multitargeted inhibitor of vascular endothelial growth factor receptor-1, -2, and -3, platelet-derived growth factor receptor-alpha and -beta, and other kinases implicated in tumor growth, angiogenesis, and metastasis. Sunitinib has been approved in metastatic renal cell carcinoma and gastrointestinal stromal tumor and is undergoing active clinical development in HCC. Early evidence of antitumor activity and a promising safety profile for this agent have emerged from single arm phase II trials in United States, European, and Asian patients with advanced HCC. Correlative studies of imaging and circulating biomarkers have provided insights into the potential mechanism of action of sunitinib. Additional phase II studies using either single agent or in combination with chemotherapeutic agents are ongoing, and a phase III trial comparing sunitinib and sorafenib in advanced HCC is actively accruing patients. Here, we review the current progress and future directions for the development of sunitinib in advanced HCC.
