lenvatinib

Lenvimamulti-kinase inhibitor

Lenvima (lenvatinib) is an oral multi-kinase inhibitor from Eisai that blocks VEGF and FGF receptors driving tumour blood supply. It is used in radioactive iodine-refractory thyroid cancer, advanced kidney cancer and, with pembrolizumab, in endometrial cancer.

This page is based on FDA prescribing information and the EMA medicine record for lenvatinib, cross-checked with DailyMed and MedlinePlus; the mechanism is explained in plain language, and analogies are used only where they stay accurate.

How it works

Explains what the medicine does in the body, not dosing, side effects, or safety.

An analogy

A tumour builds two lifelines: new blood vessels for supplies, and growth signals through receptor antennas. Lenvatinib cuts both at once - it blocks the VEGF and FGF docking stations so no new supply lines are built and fewer growth orders get through, and the tumour's expansion stalls.

In simple terms

Cancers depend on new blood vessels and on growth signals received through receptor proteins. Lenvatinib blocks several of these receptors, including those for VEGF and FGF. This reduces tumour blood vessel formation and interrupts growth signalling. The result is slower growth and, in many patients, shrinkage of thyroid and kidney cancers.

In depth

Lenvatinib is an oral small-molecule inhibitor of VEGFR1-3, FGFR1-4, PDGFR-alpha, RET and KIT tyrosine kinases. Dual VEGFR/FGFR blockade suppresses angiogenesis and overcomes FGFR-mediated resistance to pure VEGF-pathway inhibition. In radioactive iodine-refractory differentiated thyroid cancer it markedly prolonged progression-free survival, and combinations with pembrolizumab or everolimus extend its use in renal cell carcinoma.

How lenvatinib works

Target: VEGFR1-3, FGFR1-4, PDGFR-alpha, RET and KIT kinases

Receptor kinases that drive tumour blood vessel formation and growth signals; blocking several at once starves the tumour and slows its proliferation.

Approved uses

Approved uses differ by country and change over time. Always follow your local prescribing information.

Approved uses in United States
