What it is

Sunitinib is a multi-targeted receptor tyrosine kinase inhibitor that has been evaluated for colorectal cancer treatment, particularly in combination with standard chemotherapy regimens like FOLFIRI and FOLFOX. While primarily approved for renal cell carcinoma and gastrointestinal stromal tumors, sunitinib has shown activity against metastatic colorectal cancer by inhibiting angiogenesis and tumor growth. In colorectal cancer, it has been tested as both first-line and subsequent therapy, often in combination with fluoropyrimidine-based chemotherapy regimens.

How it works

Sunitinib inhibits multiple receptor tyrosine kinases including VEGFR-1, VEGFR-2, VEGFR-3, PDGFR- , PDGFR- , KIT, FLT3, CSF-1R, and RET. By blocking these pathways, particularly the VEGF receptors, sunitinib disrupts tumor angiogenesis and inhibits tumor cell proliferation and survival.
