Lenvatinib is a receptor tyrosine kinase (RTK) inhibitor that inhibits the kinase activities of vascular endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4). Lenvatinib also inhibits other RTKs that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (FGF) receptors FGFR1, 2, 3, and 4; the platelet derived growth factor receptor alpha (PDGFRα), KIT, and RET.
Based on x-ray crystallography and kinetic interaction studies, lenvatinib binds to the adenosine 5'-triphosphate binding site of VEGFR2 and to a neighbouring region via a cyclopropane ring and thereby inhibits tyrosine kinase activity and associated signalling pathways.
Lenvatinib is metabolized by CYP3A and aldehyde oxidase.
The most common adverse events that occurred in lenvatinib recipients were hypertension (67.8 vs. 9.2 % in the placebo group), diarrhea (59.4 vs. 8.4 %), fatigue or asthenia (59.0 vs. 27.5 %), decreased appetite (50.2 vs. 11.5 %), decreased bodyweight (46.4 vs. 9.2 %), nausea (41.0 vs. 13.7 %), stomatitis (35.6 vs. 3.8 %), palmar-plantar erythrodysethesia syndrome (31.8 vs. 8.0 %) and proteinuria (31.0 vs. 1.5 %). Adverse events that occurred in clinical trials and for which there is a warning/precaution in US manufacturer’s pre- scribing information were hypertension, cardiac dysfunction (decreased left or right ventricular function, cardiac failure or pulmonary edema), arterial thromboembolic events, hepatotoxicity, proteinuria, renal failure and impairment, gastrointestinal perforation and fistula formation, QT interval prolongation, hypocalcaemia, reversible posterior leucoencephalopathy syndrome, haemorrhagic events, and impairment of thyroid stimulating hormone (TSH) suppression. Based on the mechanism of action of lenvatinib and results from animal reproduction studies, which showed embryotoxicity, foetotoxicity and teratogenicity at lenvatinib doses below the recommended dose in humans, females of reproductive potential should be advised to use effective contraception during treatment and for at least 2 weeks following completion of therapy.
