What is Tepezza?

Tepezza (teprotumumab) is a treatment for thyroid eye disease that was developed by Horizon Pharmaceuticals. Tepezza is administered directly into the vein (an intravenous infusion) once every three weeks for a total of eight infusions.

Tepezza and Hearing Loss

Since its approval in January 2020, Tepezza has been linked to a growing number of reports of hearing loss — including some cases of irreversible hearing loss. Even so, the label on Tepezza does not include any warnings about permanent deafness.

What is the Risk?

In clinical trials, Horizon found that about 10% of patients on Tepezza reported hearing loss, vs. 0% of patients on a placebo. Most of these cases were temporary, but the study did not differentiate between mild and severe cases. The most common hearing side effects were hypoacusis (hearing loss) followed by tinnitus (ringing in the ears).

Hearing Side Effects Linked to Tepezza

  • Hearing loss
  • Deafness
  • Distorted sounds
  • Tinnitus (ringing in the ears)
  • Autophony (hearing your own voice abnormally loud)
  • Ear feels blocked or full
  • Patulous eustachian tube
  • Sensorineural hearing loss
  • And more

Tepezza Linked to 65% Risk of Hearing Loss

In March 2021, a small study published by researchers at Stanford University found that the risk of hearing loss with Tepezza could be as high as 65% of patients, according to The Endocrine Society.

To explore the risk of hearing symptoms, researchers evaluated 26 patients who were treated with at least 4 infusions of Tepezza. Seventeen patients (65%) complained of hearing symptoms.

The most common symptoms were hearing loss (23%), tinnitus or ringing in the ears (27%), ear plugging sensation (12%), and autophony, an unusually loud hearing of a person’s own voice (29%).

Out of the 17 patients with new hearing problems, four patients had new or worsening sensorineural hearing loss, which results from damaged hair cells in the inner ear.

Three patients had patulous eustachian tube, a disorder in which the channel that runs between the middle ear and back of the nose and throat stays open.

Case Reports of Irreversible Hearing Loss With Tepezza

Doctors have published a growing number of case reports describing irreversible hearing loss with Tepezza:

  • Ototoxicity and Teprotumumab (August 2021) — 61-year-old woman diagnosed with irreversible hearing loss in both ears that did not improve 4 months after she stopped taking Tepezza. She also reported hearing distorted sounds, tinnitus (ringing in the ears), and sensorineural hearing loss.
  • Teprotumumab and Hearing Loss: Case Series and Proposal for Audiologic Monitoring (January 2022) — Study describes 4 patients on Tepezza who developed severe hearing loss that did not improve. The researchers theorized a mechanism of how Tepezza could damage hearing, “likely resulting from the inhibition of the insulin-like growth factor-1 and the insulin-like growth factor-1 receptor pathway.”
