Tepezza and Thyroid Eye Disease

Thyroid eye disease (TED) is a rare autoimmune disorder that affects the eyes, causing inflammation and swelling behind the eyeball.

The condition is most commonly associated with Graves’ disease, an autoimmune disorder that causes the thyroid gland to produce too much thyroid hormone.

That’s why many people may know TED as Graves’ eye disease, Graves’ ophthalmopathy, or Graves’ orbitopathy.

TED can cause a range of symptoms, including:

  • Eye pain
  • Redness
  • Puffiness
  • Dry eyes
  • Light sensitivity
  • Difficulty moving the eyes

Severely affected individuals may also experience the following symptoms:

  • Proptosis or eye protrusion
  • Diplopia or double vision
  • Corneal damage
  • Temporary vision loss

If left untreated, Thyroid Eye Disease can lead to permanent vision loss and disfigurement of the eyes, significantly affecting a person’s quality of life.

The condition can cause debilitating symptoms like severe eye pain, inflammation, and sensitivity to light, making daily activities challenging.

In advanced stages, it may result in bulging eyes and double vision, severely impacting the ability to see clearly and engage in normal activities.

The cosmetic changes and vision impairment associated with Thyroid Eye Disease can lead to psychological distress and a decrease in self-esteem, highlighting the importance of timely and effective treatment.

Tepezza Treatment for TED

Manufactured by Horizon Therapeutics, Tepezza (teprotumumab) is an injectable medication used to treat active thyroid eye disease and has been shown to improve symptoms and reduce inflammation in clinical trials.

The Tepezza infusion works by targeting a protein called insulin-like growth factor-1 receptor (IGF-1R), which contributes to the development of TED.

By blocking this protein, Tepezza can reduce inflammation and swelling behind the eyes, improving symptoms and preventing permanent vision loss.

Patients typically go to a hospital or infusion center to receive Tepezza infusions.

A medical professional will administer the medication through an intravenous (IV) infusion, where they will insert a needle into a vein in the hand or arm.

The infusion process can take up to 90 minutes.

In general, receiving Tepezza infusions involves completing a course of eight treatments.

Patients usually receive treatments every three weeks for a total of 24 weeks.

Doctors may adjust the treatment schedule according to individual responses and side effects.

Since the U.S. Food and Drug Administration (FDA) approved Tepezza on January 21, 2020, it has been the first and only FDA-approved medication for active thyroid eye disease.

The FDA approval of Tepezza has been a significant development for patients with chronic/low clinical activity score (CAS) TED, as there have previously been no FDA-approved treatments.

Tepezza Side Effects and Injuries

Tepezza, while effective in treating Thyroid Eye Disease, can lead to various side effects, ranging from mild to severe.

These side effects encompass a wide spectrum of physical reactions, some of which may be temporary, while others could have more lasting implications.

It is crucial to talk to your doctor and to be vigilant in monitoring for any adverse effects during and after the treatment course.

The severity of these side effects can differ significantly among individuals, with some experiencing only minor discomforts, whereas others may encounter more serious complications.

It’s important to note that while some side effects are common and expected, others, particularly those affecting hearing, have raised concerns and led to legal action.

Patients experiencing any unusual or persistent side effects are advised to seek medical attention promptly and consider legal consultation if their health has been adversely affected.

Here are common Tepezza side effects, as listed on the Tepezza website.

Dysgeusia is one of the adverse reactions listed in the original Tepezza label.

This condition causes a change in taste perception, causing food or drinks to taste different than usual.

Some people may experience a metallic or bitter taste in their mouth, affecting their appetite and enjoyment of food.

In some cases, burning mouth syndrome, a condition characterized by a burning sensation, may also occur.

In the clinical trial, 8% of patients reported taste changes as a side effect.

However, this condition was mild for all patients and no one discontinued treatment.

5% of patients in the clinical trial observed changes in their nails, such as broken nails and color changes.

However, these effects were not painful or bothersome.

Change in Menstruation

Women may experience changes in their menstrual cycle as a side effect of Tepezza.

In the clinical trial, 5 out of 22 menstruating patients experienced changes in their menstrual cycle during treatment with Tepezza.

These women reported spotting, cramps, menstrual pain, and missing periods.

However, most returned to their regular cycle after completing treatment.

Infusion Reaction

In some cases, patients may experience infusion reactions during or after receiving Tepezza infusions.

These reactions can include:

  • High Blood Pressure
  • Fast Heartbeat
  • Redness of the Face
  • Feeling Hot
  • Difficulty Breathing
  • Headache
  • Muscle Pain

Some patients may also experience allergic reactions, such as flushing, itchiness, and skin rash, either from the medication or the intravenous infusion.

In the clinical trial, one patient with a history of IBD experienced a flare-up during treatment.

Possible Effects on Pregnancy

Tepezza can potentially harm a developing fetus and should not be used during pregnancy.

Female patients who are pregnant or plan to become pregnant must discuss treatment options with their doctor before starting Tepezza.

Additionally, women of reproductive age must use effective birth control before the first dose, during treatment, and for at least six months after the last Tepezza infusion.

Tepezza and Hearing Loss

In the clinical trials, 10% of patients experienced hearing loss as a side effect.

They reported hearing problems, such as: 

  • Deafness
  • One or both ears obstructed with fluid
  • Issues in loudness perception
  • Impairment in hearing certain sounds

However, it’s crucial to note that the clinical trials took place before the FDA’s approval.

In 2021, the Endocrine Society published a study on the link between hearing loss and Tepezza treatment.

They found that 65% of patients had hearing problems after an average of 3.6 Tepezza infusions.

The most common symptoms included:

  • Subjective Hearing Loss: Patients feel like their hearing has decreased but cannot notice any significant changes in loudness.
  • Tinnitus: Patients hear a ringing, buzzing, or humming sound in their ears.
  • Ear Plugging Sensation: Patients feel like they have cotton or fluid in their ears.
  • Autophony: Patients hear their own voice or breathing too loudly.

Additionally, four of the Endocrine Society study’s patients experienced new or worsened sensorineural hearing loss, a permanent type of hearing loss caused by nerve damage in the inner ear.

Three patients had a patulous eustachian tube, a condition where the eustachian tube stays open, causing ear fullness or autophony.

Growing Concerns on Tepezza and Hearing Loss

The increasing number of patients experiencing hearing loss during Tepezza treatment has raised concerns among the medical community.

As Tepezza infusions can potentially result in permanent hearing impairment, more research is necessary to understand the medication’s impact on hearing and its possible long-term effects.

The FDA updated Tepezza’s prescribing information in 2023 to include a warning about potential hearing loss as a side effect. In some cases, permanent hearing loss may occur after Tepezza infusions.

The FDA urges healthcare providers to assess their patients’ hearing before and during treatment with Tepezza and monitor for any changes in hearing after completing treatment.

Patients must disclose any pre-existing medical conditions and use of prescription drugs and dietary and herbal supplements to their doctor before starting Tepezza treatment.

    Tepezza is used for the treatment of Thyroid Eye Disease, also called Graves’ Eye Disease, a condition that affects the muscles and tissues around the eyes.

    This drug is specifically designed to reduce the symptoms associated with this autoimmune disorder, such as inflammation, swelling, and bulging of the eyes.
