Were you treated with Tepezza®? If you had known that it might cause temporary or permanent hearing loss would you have opted for the treatment?

Do you qualify?

When you were treated with the drug Tepezza® did you know that you might end up with temporary or permanent hearing loss? It would have been difficult to decide if potential hearing loss was worth the treatment for bulging eyes, pain and other symptoms found in patients with Graves’ disease and other conditions.

If you suffered hearing loss connected with Tepezza® use, you may qualify to join a lawsuit to receive compensation for this unexpected and unpleasant change in your life.

Tepezza: overview

Tepezza is an infusion medication manufactured by Horizon Therapeutics that is used to treat eye bulging and double vision. The medication may also treat thyroid eye disease symptoms such as eye pain, eye redness and eye swelling. Thyroid eye disease is a relatively rare disease that occurs as a result of Graves disease, an autoimmune disorder involving an overactive thyroid.

Tepezza was approved by the FDA in January 2020.

“Today’s approval marks an important milestone for the treatment of thyroid eye disease,” said Dr. Wiley Chambers, deputy director of the Division of Transplant and Ophthalmology Products at the FDA’s Center for Drug Evaluation and Research, in an approval news release.

“This treatment has the potential to alter the course of the disease, potentially sparing patients from needing multiple invasive surgeries by providing an alternative, non-surgical treatment option.”

According to the official Tepezza website, common Tepezza side effects include:

  • Muscle cramps or spasms
  • Nausea
  • Hair loss
  • Diarrhea
  • Feeling tired
  • High blood sugar
  • Hearing problems
  • Taste changes
  • Headache
  • Dry skin
  • Weight loss
  • Nail problems
  • Changes in menstruation

Unfortunately, Tepezza may also be associated with a more serious side effect: permanent hearing loss.

Tepezza hearing loss

In the two studies used to approve Tepezza, hearing problems were reported in 10% of patients. A 2021 study presented in March 2021 at the Endocrine Society’s annual meeting suggests that this rate could be much higher. The study, which evaluated 26 patients treated with Tepezza, found that 65% of the patients suffered from hearing problems. Symptoms recorded by the study included:

  • Hearing loss (experienced by 23% of patients)
  • Tinnitus or ringing in the ears (experienced by 27% of patients)
  • Ear plugging sensations (12% of patients)
  • Autophony or an unusually loud hearing of one’s own voice (experienced by 29% of patients)

According to the study, Tepezza hearing loss can take many forms. Some patients experienced sensorineural hearing loss, which is a result of damaged hair cells in the inner ear. Others experienced patulous eustachian tube, a disorder in which a channel between the middle ear and the nose and throat area remains open constantly instead of opening only to regulate air pressure in the ear.

Unfortunately, hearing loss was permanent in some of these cases. After three months, some symptoms improved while others remained, even after stopping the drug.

In February 2022, a post-marketing safety analysis from Horizon Therapeutics confirmed the risk of Tepezza hearing loss, though Horizon’s trials only found hearing-related side effects in 9.5% of patients.

Due to the results of these studies, the FDA approved a label change for Tepezza in July 2023. The new label includes a warning for “hearing impairment including hearing loss, which in some cases may be permanent.”

Although the 2023 Tepezza label change helps warn patients and doctors of the potential risks for hearing loss, patients who were not warned of this risk in the past may be able to take legal action for their hearing loss and related injuries. Patients may not have chosen Tepezza treatment if they had known about the risks for hearing loss, but they were unable to make an informed choice because they were not warned of these risks for years before the 2023 label change.
