Lenvatinib Powder Description

Lenvatinib powder is an anti-cancer drug for the treatment of certain kinds of thyroid cancer and for other cancers as well. It was acts as a multiple kinase inhibitor against the VEGFR1, VEGFR2 and VEGFR3 kinases.

Lenvatinib powder is a type of targeted therapy. This means it targets something specific to the cancer cells, therefore decreasing side effects caused by damage to the healthy cells. Lenvatinib powder works by blocking two processes that allow cancer cells to grow:

▪ Interfering with a protein that promotes cell division

▪ Blocking the VEGF receptor, which is responsible for angiogenesis, or the development of a blood supply to the tumor. This removes the tumor’s source of nutrients.


Lenvatinib Powder Mechanism of Action

Lenvatinib powder 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 powder 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.


Lenvatinib Powder Application

♦ For the treatment of patients with locally recurrent or metastatic, progressive, radioactive iodine-refractory differentiated thyroid cancer.

♦ In combination with the drug everolimus, for the treatment of advanced renal cell carcinoma following one prior anti-angiogenic therapy.

♦ Treatment of hepatocellular (primary liver) cancer.

♦ In combination with the drug pembrolizumab for treatment of patients with advanced endometrial cancer.

Note: If a drug has been approved for one use, physicians may elect to use this same drug for other problems if they believe it may be helpful.

▪ low calcium level–muscle spasms or contractions, numbness or tingly feeling (around your mouth, or in your fingers and toes);

▪ increased blood pressure–severe headache, blurred vision, pounding in your neck or ears, anxiety, nosebleed.

Your cancer treatments may be delayed or permanently discontinued if you have certain side effects.


Common side effects may include:

▪ bleeding;

▪ stomach pain, nausea, vomiting, diarrhea;
