UPDATE: 1st Tepezza Lawsuit Filed for Hearing Loss

In August 2022, the first Tepezza lawsuit for hearing loss was filed by a man from Arizona who accuses Horizon Pharmaceuticals of failing to warn about the risk of permanent hearing damage from Tepezza.

The lawsuit was filed by Daniel W., a man who was treated with infusions of Tepezza between June 2020 and September 2020. He said he was given no warnings about the risk of hearing damage.

Soon after his treatment with Tepezza, he was diagnosed with hearing loss and tinnitus (ringing in his ears).

He accuses Horizon Pharmaceuticals of failing to recommend that patients undergo audiological monitoring, “despite study after study providing clear evidence” linking Tepezza and hearing loss.

The Tepezza Lawsuit was filed on August 25, 2022 in the U.S. District Court for the Northern District of Illinois — Case Number 1:22-cv-04518.

What is Tepezza?

Tepezza (teprotumumab) is the first-ever medication approved in the U.S. to treat thyroid eye disease. It was developed by Horizon Pharmaceuticals and approved by the FDA in January 2020.

What is the Problem?

Tepezza has been linked to many reports of hearing loss since it was approved. Horizon Pharmaceuticals conducted a post-marketing study in which about 10% of patients experienced hearing loss, vs. 0% of patients on a placebo (sugar pill).

The most frequently reported hearing event was hypoacusis (reduction in hearing), followed by tinnitus (ringing in the ears). The label on Tepezza indicates that hearing loss was reversible — but there is no warning about the risk of irreversible hearing loss.

Tepezza and Hearing Side Effects

  • Hearing loss
  • Deafness
  • Sound distortion
  • Sensorineural hearing loss
  • Feeling like the ear is blocked or full
  • Tinnitus (ringing in the ears)
  • Hypoacusis (reduced hearing ability)
  • Patulous eustachian tube
  • Autophony (hearing your own voice abnormally loud)
  • And more

Study Finds 65% Risk of Hearing Loss from Tepezza

In March 2021, The Endocrine Society published a small study that found 65% of patients on Tepezza reported hearing problems.

The study included 26 patients who were treated with at least four infusions of Tepezza. Seventeen (65%) of the patients reported new hearing problems. The most common were hearing loss (23%), ringing in the ears (27%), ear plugging sensation (12%) and autophony, an unusually loud hearing of a person’s own voice (29%).

Three patients developed a long-term hearing problem called patulous eustachian tube, a disorder in which the channel that runs between the middle ear and back of the nose and throat stays open. The symptoms improved with time, but they did not go away entirely.

Case Reports of Irreversible Hearing Loss

  • August 2021 — “Ototoxicity and Teprotumumab” — Case report of a 61-year-old woman who suffered irreversible hearing loss in both ears, sound distortion, tinnitus, sensorineural hearing loss. Her hearing loss was unchanged 4 months after stopping Tepezza and taking oral corticosteroids.
  • January-February 2022 — “Teprotumumab and Hearing Loss: Case Series and Proposal for Audiologic Monitoring” — Four case reports of severe hearing loss in patients on Tepezza, “likely resulting from the inhibition of the insulin-like growth factor-1 and the insulin-like growth factor-1 receptor pathway.”

What is Thyroid Eye Disease?

Thyroid eye disease (also known as “Graves’ eye disease”) is an autoimmune disease in which an overactive thyroid gland causes the eye muscles and fatty tissue behind the eye to become inflamed. The symptoms can include dry eyes, watery eyes, red eyes, bulging eyes, a “stare,” double vision, and more.
