Description

Tivozanib (formerly AV-951, KRN-951) is a potent and selective VEGFR tyrosine kinase inhibitor and inhibits angiogenesis and vascular permeability in tumor tissues. It completed phase III a trial investigation for the treatment of renal cell carcinomas, but has not been still approved. In addition, this drug is in the phase II of clinical trial for the investigation it in patients with glioblastoma and colorectal carcinoma.

Sample Use Guides

In Vivo Use Guide
Advanced Renal Cell Carcinoma: 1.5 mg orally once daily. Subjects will receive 1.5 mg tivozanib once daily beginning on Day 1 for 3 weeks followed by 1 week off treatment. One cycle will be defined as 4 weeks of treatment. Cycles will be repeated every 4 weeks.
Route of Administration: Oral
In Vitro Use Guide
KRN951 (TIVOZANIB) potently inhibited VEGF-induced VEGFR-2 phosphorylation in endothelial cells at in vitro subnanomolar IC50 values (IC50 = 0.16 nmol/L). It also inhibited ligand-induced phosphorylation of platelet-derived growth factor receptor-beta (PDGFR-beta) and c-Kit (IC50 = 1.72 and 1.63 nmol/L, respectively). KRN951 blocked VEGF-dependent, but not VEGF-independent, activation of mitogen-activated protein kinases and proliferation of endothelial cells. In addition, it inhibited VEGF-mediated migration of human umbilical vein endothelial cells.
