Question 1

What is Tepezza?

Accepted Answer

Tepezza is a monoclonal antibody that belongs to a class of medications known as insulin-like growth factor-1 receptor inhibitors. It works by binding to specific receptors on cells to block the biological processes that cause inflammation and tissue expansion behind the eyes.

This mechanism of action helps manage the underlying causes of thyroid eye disease by focusing on the biological pathways responsible for the condition. By targeting these receptors, the medication helps reduce the inflammation and swelling associated with the disease.

Question 2

What is Tepezza used for?

Accepted Answer

Tepezza is used to treat thyroid eye disease .

Question 3

How does Tepezza work?

Accepted Answer

Mechanism of Action

Tepezza is a monoclonal antibody designed to target and block the insulin-like growth factor-1 receptor (IGF-1R). This receptor is found on the surface of various cells throughout the body, including the cells behind the eyes.

How it Affects Thyroid Eye Disease

In people with thyroid eye disease (TED), the immune system mistakenly attacks the muscles and fatty tissues located behind the eyes. This process involves cells called fibroblasts, which have an unusually high number of IGF-1R proteins. When these receptors are activated, they cause the fibroblasts to produce inflammation and lead to the buildup of extra tissue and fat.

Tepezza works by attaching itself to the IGF-1R. By doing so, it acts like a shield that prevents other proteins from activating the receptor. This blocking action helps to:

Reduce inflammation: It calms the immune response in the eye socket.

Decrease tissue growth: It stops the overproduction of fat and muscle tissue behind the eye.

Relieve pressure: By reducing the volume of tissue, it helps the eyes move back into a more natural position and eases pressure on the optic nerve.

By addressing the underlying biological pathway of the disease, Tepezza helps improve symptoms such as eye bulging (proptosis), double vision, and eye pain.

Question 4

What are the active ingredients in Tepezza?

Accepted Answer

The active ingredient in Tepezza is teprotumumab .

Question 5

Accepted Answer

Common side effects of Tepezza may include:

muscle spasms

nausea

hair loss

and others

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Tepezza?

Accepted Answer

Tepezza belongs to the IGF-1 receptor antagonist drug class.

Question 7

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

Accepted Answer

Administration

Tepezza is administered as an intravenous (IV) infusion into a vein. These treatments are performed by a healthcare professional in a medical setting, such as a hospital or infusion center.

Treatment Frequency

The medication is typically given as a series of infusions. These are usually scheduled once every three weeks until the full course of treatment is finished.

Infusion Process

The length of time for each infusion can change during the course of treatment. The first few infusions are generally administered slowly over a longer period. If these initial doses are well-tolerated, the remaining infusions may be given over a shorter duration.

Missed Doses

If you miss an appointment for an infusion, call your doctor or treatment center immediately to reschedule. It is important to stay on the prescribed schedule to achieve the best results from the medication.

Question 8

Is Tepezza safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Tepezza can cause harm to a developing fetus. Healthcare providers typically recommend a pregnancy test before starting treatment to ensure the patient is not pregnant. If you are pregnant or planning to become pregnant, discuss the potential risks and benefits with your doctor.

Individuals who can become pregnant should use effective birth control during treatment and for at least 6 months after the final dose of Tepezza. If you become pregnant while receiving this medication, notify your healthcare provider immediately.

Breastfeeding

It is currently unknown whether Tepezza passes into human breast milk or if it could affect a breastfeeding child. Because the risks are not fully understood, it is important to talk with a healthcare professional about the best way to feed your baby while receiving this treatment.

Question 9

What forms and strengths does Tepezza come in?

Accepted Answer

Dosage Forms

Tepezza is available as a sterile, preservative-free powder. It is provided in a vial and requires reconstitution and dilution before it can be used.

Administration

This medication is given as an intravenous infusion. It is administered by a healthcare provider in a medical setting, such as a doctor's office or infusion center.

Question 10

What is the FDA approval status of Tepezza?

Accepted Answer

FDA Approval and Indications

The U.S. Food and Drug Administration (FDA) approved Tepezza in January 2020. It was the first medication approved specifically for the treatment of Thyroid Eye Disease , a condition where the immune system attacks the muscles and fat behind the eyes, causing inflammation and bulging.

The medication is indicated for adults with Thyroid Eye Disease regardless of the disease activity or duration.

Regulatory History and Safety Updates

Tepezza was granted several special designations by the FDA during its development, including Orphan Drug , Fast Track , and Breakthrough Therapy designations, to expedite the availability of a treatment for this rare condition.

In 2023, the FDA approved a labeling update for Tepezza to include information regarding the risk of severe hearing loss . While hearing problems were known at the time of initial approval, the updated labeling reflects reports that these issues, including deafness, may be permanent in some patients.

There are currently no boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) required for this medication.

Question 11

What should I know about Tepezza and cost?

Accepted Answer

Factors Influencing Cost

Because Tepezza is a specialized biologic medication administered via intravenous (IV) infusion, its total cost is influenced by several variables:

Dosage: The amount of medication required for each session is calculated based on the patient's body weight.

Number of Treatments: A standard course of treatment typically involves eight infusions given every three weeks.

Administration Fees: Costs associated with the infusion center, nursing staff, and medical supplies are usually billed separately from the drug itself.

Insurance Coverage

Most insurance providers, including Medicare, may cover Tepezza for the treatment of thyroid eye disease. However, many plans require prior authorization, a process where a doctor must demonstrate that the medication is medically necessary before the insurer agrees to cover the cost. Out-of-pocket expenses like deductibles and co-insurance will vary depending on the specific insurance plan.

Financial Assistance Programs

Financial support may be available to help manage the costs of Tepezza. The manufacturer often provides patient support services that include:

Co-pay Assistance: Programs designed to help patients with commercial insurance reduce their out-of-pocket costs.

Patient Assistance Programs: Support for individuals who are uninsured or underinsured and meet specific financial eligibility requirements.

Patients are encouraged to work with their healthcare provider and insurance company to understand their financial responsibility before starting treatment.
