Indication:
Lenvaxen is a kinase inhibitor that is indicated:
- Differentiated Thyroid Cancer: Lenvaxen is indicated for the treatment of patients with locally recurrent or metastatic, progressive, radioactive iodine-refractory differentiated thyroid cancer (DTC).
- Renal Cell Carcinoma: Lenvaxen is indicated in combination with Everolimus for the treatment of patients with advanced renal cell carcinoma (RCC) following one prior anti-angiogenic therapy.
- Hepatocellular Carcinoma: Lenvaxen is indicated for the first-line treatment of patients with unresectable hepatocellular carcinoma (HCC).
- Endometrial Carcinoma: Lenvaxen, in combination with Pembrolizumab, is indicated for the treatment of patients with advanced endometrial carcinoma that is not microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR), who have disease progression following prior systemic therapy and are not candidates for curative surgery or radiation.
Pharmacology:
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 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.
Dosage of Lenvaxen 10 mg
Important Dosage Information: The dose reduction is needed for certain patients with renal or hepatic impairment. Lenvatinib should be taken once daily, with or without food, at the same time each day. If a dose is missed and cannot be taken within 12 hours, skip that dose and take the next dose at the usual time of administration.Recommended Dosage for Differentiated Thyroid Cancer (DTC): The recommended dosage of Lenvatinib is 24 mg orally once daily until disease progression or until unacceptable toxicity.Recommended Dosage for Renal Cell Carcinoma (RCC): The recommended dosage of Lenvatinib is 18 mg in combination with 5 mg Everolimus orally once daily until disease progression or until unacceptable toxicity.Recommended Dosage for Hepatocellular Carcinoma (HCC): The recommended dosage of Lenvatinib is based on actual body weight: 12 mg for patients greater than or equal to 60 kg or 8 mg for patients less than 60 kg. Lenvatinib should be taken orally once daily until disease progression or until unacceptable toxicity.Recommended Dosage for Endometrial Carcinoma: The recommended dosage of Lenvatinib is 20 mg orally once daily, in combination with Pembrolizumab 200 mg administered as an intravenous infusion over 30 minutes every 3 weeks, until unacceptable toxicity or disease progression.
Lenvaxen 10 mg:
Lenvatinib capsules can be swallowed whole or dissolved in a small glass of liquid. To dissolve in liquid, put capsules into 1 tablespoon of water or apple juice without breaking or crushing the capsules. Leave the capsules in the water or apple juice for at least 10 minutes. Stir for at least 3 minutes. After drinking the mixture, add 1 tablespoon of water or apple juice to the glass, swirl the contents a few times and swallow the water or apple juice.
