Sunitinib

Sunitinib is a small-molecule multi-targeted receptor tyrosine kinase (RTK) inhibitor. On January 26, 2006, the agent was formally approved by the US FDA for the indications of treating renal cell carcinoma (RCC) and imatinib-resistant gastrointestinal stromal tumor (GIST). For these purposes, sunitinib is generally available as an orally administered formulation. Sunitinib inhibits cellular signaling by targeting multiple RTKs. These include all platelet-derived growth factor receptors (PDGF-R) and vascular endothelial growth factor receptors (VEGF-R). Sunitinib also inhibits KIT (CD117), the RTK that drives the majority of GISTs. In addition, sunitinib inhibits other RTKs including RET, CSF-1R, and flt3.
