Question 1

What is Afinitor?

Accepted Answer

Afinitor is a medication that contains the active ingredient everolimus. It belongs to a class of drugs known as kinase inhibitors, specifically targeting the mammalian target of rapamycin (mTOR) protein.

This medication works by blocking signals that tell cells to multiply and grow. By inhibiting these signals, it helps to slow or stop the development of abnormal cell masses in the body.

Question 2

What is Afinitor used for?

Accepted Answer

Afinitor is used to treat the following conditions:

Renal cell carcinoma

Pancreatic neuroendocrine tumors

Breast cancer

Others

Question 3

How does Afinitor work?

Accepted Answer

Afinitor belongs to a class of medications known as mTOR inhibitors. It works by targeting a specific protein called mammalian target of rapamycin (mTOR), which acts as a control center for cell growth, division, and survival.

In many types of cancer and certain genetic conditions, the mTOR pathway becomes overactive. This causes cells to multiply too quickly and survive longer than they should. Afinitor interferes with this process in the following ways:

Inhibiting Cell Division: By binding to the mTOR protein, the drug blocks the signals that tell cells to grow and replicate. This helps slow down the spread of cancer cells or the growth of non-cancerous tumors.

Restricting Blood Flow: The medication helps reduce the production of vascular endothelial growth factor (VEGF), a substance that triggers the growth of new blood vessels. By limiting the blood supply, the drug starves the tumor of the oxygen and nutrients it needs to grow.

Managing Genetic Conditions: In conditions like tuberous sclerosis complex (TSC), genetic mutations cause the mTOR pathway to be constantly active. Afinitor helps regulate this pathway, which can lead to the shrinking of specific types of tumors associated with the condition.

Question 4

Question 6

What drug class is Afinitor?

Accepted Answer

Question 7

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

Accepted Answer

How to Take Afinitor

Afinitor is available as regular tablets and as tablets for oral suspension. It is usually taken once a day at the same time every day. You should follow your healthcare provider's instructions exactly and do not change your dose or stop taking the medication without consulting them.

Administration Instructions

Regular Tablets: Swallow the tablets whole with a glass of water. Do not crush, chew, or break the tablets.

Tablets for Oral Suspension: These tablets must be mixed with water to create a liquid suspension before taking. Do not swallow these tablets whole, and do not chew or crush them.

Food Consistency: You may take this medication with or without food, but you must choose one way and do it the same way every time to keep the amount of medicine in your body stable.

Missed Doses

If you miss a dose of Afinitor, take it as soon as you remember if it is within a short window of the scheduled time. If too much time has passed since the missed dose, skip it and take your next dose at the regularly scheduled time. Do not take two doses at once to make up for a missed one.

Handling Precautions

Caregivers should avoid direct contact with the tablets or the suspension. It is recommended to wear gloves when handling the medication, especially for individuals who are pregnant or may become pregnant.

Question 8

Is Afinitor safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Afinitor can cause harm to a fetus if taken during pregnancy. Animal studies have shown that the medication may lead to developmental issues or pregnancy loss. It is important to inform a healthcare provider if you are pregnant or planning to become pregnant before starting this medication.

Effective birth control is necessary during treatment:

Females: Those who can become pregnant should use highly effective contraception while taking Afinitor and for 8 weeks after the final dose.

Males: Men with female partners who can become pregnant should use effective contraception during treatment and for 4 weeks after the final dose.

Breastfeeding

It is currently unknown if Afinitor passes into human breast milk. Because of the potential for serious side effects in a nursing infant, breastfeeding is not recommended during treatment and for at least 2 weeks after the last dose.

Fertility

This medication may affect fertility in both men and women, which could impact the ability to conceive a child. Patients should discuss these risks with their healthcare team.

Question 9

What forms and strengths does Afinitor come in?

Accepted Answer

Afinitor is supplied in two distinct oral formulations:

Oral Tablets: These are standard tablets intended to be swallowed whole with water.

Tablets for Oral Suspension: Known as Afinitor Disperz, these tablets are designed to be dissolved in water to create a liquid suspension before administration.

These two forms of the medication are not interchangeable. The tablets for oral suspension are prepared differently and are absorbed by the body differently than the standard oral tablets. Patients should use only the specific form that has been prescribed for them.

Question 10

What is the FDA approval status of Afinitor?

Accepted Answer

FDA Approval and Indications

Afinitor was first approved by the U.S. Food and Drug Administration (FDA) in 2009. It is currently approved for the treatment of several specific conditions:

Breast Cancer: Used in combination with exemestane for postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer.

Neuroendocrine Tumors (NET): Used for adults with progressive tumors of pancreatic origin, as well as certain types of lung or gastrointestinal origin that cannot be removed by surgery.

Renal Cell Carcinoma: Used for advanced kidney cancer when other treatments have not worked.

Tuberous Sclerosis Complex (TSC): Used for specific tumors including subependymal giant cell astrocytoma (SEGA) and renal angiomyolipoma, as well as for certain types of seizures associated with TSC.

Regulatory Oversight and Safety Monitoring

The FDA continues to monitor the safety of Afinitor through the FDA Adverse Event Reporting System (FAERS). This system identifies potential signals of serious risks or new safety information. When a signal is identified, the FDA evaluates the data to decide if regulatory action, such as updating the drug's labeling or issuing a safety communication, is required.

Afinitor is classified as a kinase inhibitor, specifically an mTOR inhibitor. While it is approved for several indications, its use must be managed by a healthcare professional experienced in the use of anticancer therapies.

Question 11

What should I know about Afinitor and cost?

Accepted Answer

Factors Affecting Cost

The price of Afinitor can vary significantly based on the following:

Insurance Coverage: Most insurance plans, including Medicare and Medicaid, provide coverage for Afinitor, but out-of-pocket costs like copays or coinsurance will vary depending on the specific plan.

Generic Availability: A generic version of Afinitor, called everolimus, is available and is generally less expensive than the brand-name drug.

Pharmacy Type: Because Afinitor is a specialty medication, it is often dispensed through specialty pharmacies rather than standard retail pharmacies, which may affect how the drug is billed.

Financial Assistance

Patients who are prescribed Afinitor may have access to financial support options to help manage out-of-pocket expenses:

Manufacturer Programs: The drug manufacturer may offer copay cards or patient assistance programs to help reduce costs for eligible individuals with commercial insurance or those who are uninsured.

Support Organizations: Some non-profit organizations provide grants or assistance for medications used to treat cancer or certain genetic conditions.

It is recommended to contact your insurance provider and the specialty pharmacy to get an accurate estimate of your specific costs and to inquire about available assistance programs.
