Lenvatinib (E7080) is an oral, multi-targeted tyrosine kinase inhibitor that inhibitsVEGFR1-3,FGFR1-4,PDGFR,KIT, andRET, shows potent antitumor activities^[1][2].

Lenvatinib (E7080) 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, and 100 nM, respectively^[3].

Lenvatinib (E7080) (100 mg/kg, p.o.) 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 (E7080) 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 STI571 treatment^[4].
