Question 1

What is Lenvatinib?

Accepted Answer

Lenvatinib belongs to a class of medications known as kinase inhibitors. It works by blocking the action of specific proteins that signal cancer cells to multiply and form new blood vessels.

By inhibiting these proteins, the medication helps to slow down or stop the progression of the disease. This targeted approach focuses on the specific mechanisms that allow cancer to grow and survive in the body.

Question 2

What is Lenvatinib used for?

Accepted Answer

Lenvatinib is used to treat:

Differentiated thyroid cancer

Renal cell carcinoma

Hepatocellular carcinoma

Others

Question 3

How does Lenvatinib work?

Accepted Answer

Mechanism of Action

Lenvatinib belongs to a class of drugs called kinase inhibitors. It works by identifying and blocking specific proteins, known as kinases, that are found on the surface of both cancer cells and healthy cells. These proteins act as signaling pathways that tell cells when to grow and divide.

Blocking Blood Vessel Growth

A key way lenvatinib works is by inhibiting vascular endothelial growth factor (VEGF) receptors. Cancerous tumors often trigger the growth of new blood vessels to supply themselves with the oxygen and nutrients they need to expand. By blocking these receptors, lenvatinib interferes with this process, which is known as angiogenesis, effectively helping to starve the tumor.

Targeting Multiple Pathways

Lenvatinib is considered a multi-kinase inhibitor because it targets several different types of proteins at once, including:

Fibroblast growth factor (FGF) receptors

Platelet-derived growth factor (PDGF) receptors

RET and KIT proteins

By interfering with these multiple signaling pathways, the medication helps slow or stop the spread of cancer cells throughout the body.

Question 8

What is the dosage of Lenvatinib and how do I take it?

Accepted Answer

How to Take Lenvatinib

Lenvatinib is an oral medication usually taken once a day. It should be taken at the same time each day to maintain consistent levels in the body. You may take this medication with or without food.

Administration Instructions

Capsules should be swallowed whole. For patients who have difficulty swallowing, the capsules can be dissolved in a small amount of water or apple juice. Do not crush or chew the capsules. When dissolving the capsules in liquid, ensure the entire mixture is consumed immediately to receive the full dose.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is close to the time for the next scheduled dose, skip the missed dose and continue with the regular routine. Do not take extra medicine to compensate for a missed dose.

Question 9

Is Lenvatinib safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Lenvatinib may cause fetal harm if taken during pregnancy. It is important to inform a healthcare provider if you are pregnant or planning to become pregnant before starting this medication. If you become pregnant while taking this drug, notify your doctor immediately.

Contraception Requirements

Because of the risks to a developing fetus, healthcare providers typically recommend the following:

For females: Use effective birth control during treatment and for at least 30 days after the final dose.

For males: Men with female partners who can become pregnant should use effective contraception during treatment and for at least 30 days after the last dose.

Breastfeeding

It is not known whether lenvatinib passes into human breast milk. Due to the potential for serious side effects in a nursing infant, breastfeeding is generally not recommended during treatment with lenvatinib and for at least one week following the last dose.

Question 10

What forms and strengths does Lenvatinib come in?

Accepted Answer

Lenvatinib is available as a capsule for oral administration. These capsules are typically provided in blister cards.

If the capsules cannot be swallowed whole, they may be dissolved in water or apple juice to create a liquid mixture. This preparation should be handled according to specific medical instructions to ensure the full dose is received.

Question 11

What is the FDA approval status of Lenvatinib?

Accepted Answer

FDA Approval and Indications

Lenvatinib was first approved by the U.S. Food and Drug Administration (FDA) in 2015. It is currently approved for the following clinical uses:

Differentiated Thyroid Cancer (DTC): For the treatment of patients with local recurrence or metastatic, progressive differentiated thyroid cancer that is refractory to radioactive iodine treatment.

Renal Cell Carcinoma (RCC): Approved for use in combination with everolimus for patients with advanced kidney cancer following one prior anti-angiogenic therapy. It is also approved in combination with pembrolizumab as a first-line treatment for adults with advanced RCC.

Hepatocellular Carcinoma (HCC): As a first-line treatment for patients with unresectable liver cancer.

Endometrial Carcinoma: In combination with pembrolizumab for patients with advanced endometrial carcinoma that is not microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR), whose disease has progressed following prior systemic therapy and who are not candidates for curative surgery or radiation.

Regulatory Safety Information

The FDA has not issued a Boxed Warning for lenvatinib, and there is currently no Risk Evaluation and Mitigation Strategy (REMS) program required for its distribution. However, the FDA requires the manufacturer to provide a Medication Guide for patients to highlight potential serious risks, such as high blood pressure, heart problems, and gastrointestinal perforations. The drug is also listed in the FDA Table of Pharmacogenomic Biomarkers because its use in endometrial cancer is specific to the MSI-H or dMMR status of the tumor.

Question 12

What should I know about Lenvatinib and cost?

Accepted Answer

Insurance and Out-of-Pocket Costs

The price of lenvatinib is largely determined by individual health insurance plans. Patients may be responsible for copayments, coinsurance, or meeting a deductible before coverage begins. Because it is a specialty medication, it is often placed on a higher tier of an insurance formulary, which can result in higher out-of-pocket costs.

Specialty Pharmacy Access

Lenvatinib is typically not available at local retail pharmacies. It is usually dispensed through specialty pharmacies that handle complex medications. These pharmacies often provide additional services, such as help with insurance navigation and financial assistance applications.

Financial Assistance Programs

Various programs may help reduce the cost of lenvatinib for eligible patients:

Manufacturer Assistance: Programs may be available to provide the medication at no cost or a reduced cost for those who meet specific income and insurance requirements.

Co-pay Support: Patients with commercial insurance may qualify for co-pay cards to lower their monthly expenses.

Charitable Foundations: Independent organizations sometimes offer grants to help patients cover the costs of oncology medications.

Patients are encouraged to speak with their healthcare provider or a social worker to explore available financial resources.
