Lenvatinib (E7080) is an oral, multi-targeted tyrosine kinase inhibitor that inhibits VEGFR1-3, FGFR1-4, PDGFR, KIT, and RET, 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].

H146 (1.2×10³ cells/50 μL/well) in SFM containing 0.5% BSA are cultured in 96-well multi-plates. After overnight culture at 37°C, SFM (150 μL/well) containing 0.5% FBS and several concentrations of SCF are added with or without several concentrations of compound. After culture for 72 hr, the ratios of surviving cells are measured by WST-1.

Female BALB/c nude mice (8-12 weeks old, 20-25 g) are maintained under clean-room conditions. H146 tumor cells (6.5×10⁶) are implanted subcutaneously (s.c.) into the flank region of mice. Twelve days after inoculation, mice are randomized into control (n=12) and treatment (n=6 or n=5) groups and this point in time is identified as day 1. Lenvatinib and STI571, and VEGF neutralization antibody are suspended in 0.5% methylcellulose and saline, respectively, and administered orally twice a day for lenvatinib and STI571 and twice a week for antibody from day 1 to day 21. Tumor volume is measured on the indicated days and calculated. Antitumor activity is shown as a relative tumor volume (RTV=calculated tumor volume at indicated days/volume on day 1).
