Linifanib (ABT-869) is a structurally novel, receptor tyrosine kinase (RTK) inhibitor that is a potent inhibitor of members of the vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) receptor families, but has much less activity against unrelated RTKs, soluble tyrosine kinases, or serine/threonine kinases. Linifanib (ABT-869) does not have a general antiproliferative effect due to its high dose requirement. However, it may exhibit potent antiproliferative and apoptotic effects on tumor cells whose proliferation is dependent on mutant kinases, such as FMS-related tyrosine kinase receptor-3 (FLT3). Linifanib (ABT-869) was in phase III clinical trial for the treatment of hepatocellular carcinoma, but the study failed to meet the primary end point.

Sample Use Guides

Linifanib 17.5 mg once daily.
Route of Administration: Oral
Linifanib (ABT-869) is a receptor tyrosine kinase (RTK) inhibitor that is a potent inhibitor of members of the vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) receptor families (e.g., KDR IC50 = 4 nmol/L) but has much less activity (IC50s > 1 uM/L) against unrelated RTKs, soluble tyrosine kinases, or serine/threonine kinases. The inhibition profile of ABT-869 is evident in cellular assays of RTK phosphorylation (IC50 = 2, 4, and 7 nmol/L for PDGFR-beta, KDR, and CSF-1R, respectively) and VEGF-stimulated proliferation (IC50 = 0.2 nmol/L for human endothelial cells).
