SU-14813 is an oral, multitargeted tyrosine kinase inhibitor (TKI) targeting vascular endothelial growth factor receptors (VEGFR), platelet-derived growth factor receptors (PDGFR), KIT, and fms-like tyrosine kinase 3 (FLT-3). SU-14813 was developed as a next-generation TKI agent following sunitinib (SU-11248) designed to demonstrate optimized pharmacokinetic (PK) and tolerability profiles. SU14813 demonstrated broad and potent antitumor activity equivalent to that of sunitinib, which resulted in tumor regression, growth arrest, growth delay, and prolonged survival in established xenograft cancer models in mice. A phase II trial of SU-14813 in patients with breast cancer was completed. However, according to the Pfizer pipeline development has been discontinued.
