Lenvatinib mesylate (E7080 mesylate), an oral, multi-targeted tyrosine kinase inhibitor that inhibits VEGFR1-3, FGFR1-4, PDGFR, KIT, and RET, shows potent antitumor activities[1][2].
Lenvatinib mesylate (E7080 mesylate) has IC50s of 4, 5.2, 22 nM for VEGFR2(KDR), VEGFR3(Flt-4), and VEGFR1/Flt-1, respectively. Lenvatinib inhibits PDGFRα, PDGFRβ, FGFR1, and KIT with IC50s of 51, 39, 46, 100 nM, respectively[3].
Lenvatinib mesylate (E7080 mesylate) (100 mg/kg, p.o.) is administeredand bevacizumab significantly inhibits local tumor growth at the m.f.p., and at the end of treatment, Lenvatinib mesylate also significantly inhibits metastasis to both regional lymph nodes and distant lung[3].
Lenvatinib mesylate (E7080 mesylate) inhibits the growth of H146 tumor at 30 and 100 mg/kg (BID, QDx21) in a dose-dependent manner and causes tumor regression at 100 mg/kg in H146 xenograft model. IHC analysis with anti-CD31 antibody shows that lenvatinib at 100 mg/kg decreases microvessel density more than anti-VEGF antibody and imatinib treatment[4].
