The complaint filed by the attorneys representing David Weibel states that Horizon Therapeutics ignored relevant safety concerns relating to hearing loss and hearing related side effects.

It is currently too early to tell what the average Tepezza settlement amount will be.

We’re here to help.

At least 10 individuals who have suffered hearing loss from Tepezza have had their cases included in a motion filed in in the U.S. District Court for the Northern District of Illinois, and asking the court to consolidate the hearing loss lawsuits before one judge.

Horizon Therapeutics, the maker of Tepezza, has been accused of knowing about hearing loss risks of Tepezza, yet failing to warn about the importance of monitoring during treatment.

It is expected that more Tepezza lawsuits will be filed in the coming months, as former users discover that their hearing loss was caused by the thyroid eye disease infusion.

Horizon has objected to the call to consolidate Tepezza hearing loss lawsuits, claiming the cases will be too different to benefit from pretrial coordination.

What is Tepezza?

Tepezza is a drug used to treat Thyroid Eye Disease (TED), produced by drug manufacturer Horizon Therapeutics.

Tepezza’s “mechanism of action” is to block IGF-1R, a protein found on the surface of human cells and a key driver of Thyroid Eye Disease (TED).

By doing so, symptoms of TED are reduced, such as swelling, inflammation, double vision, blurred vision and other vision problems.

Tepezza Linked to Hearing Related Side Effects

Tepezza received FDA approval in January 2020.

There were two clinical trials conducted in Europe and the United States with over 170 participants diagnosed with Thyroid Eye Disease (TED).

What is Thyroid Eye Disease (TED)?

Thyroid Eye Disease is an eye disorder that causes swelling and inflammation to muscles, fatty tissue and connective tissue surrounding the eyes.

Thyroid Eye Disease is an autoimmune condition:

A condition that causes a person’s immune system to attack their own body.

Graves Disease is closely related to Thyroid Eye Disease.

Graves Eye Disease is an autoimmune condition that impacts a person’s eyes, thyroid and skin.

Graves Disease can cause hyperthyroidism (production of too many thyroid hormones) or hypothyroidism (lack of thyroid hormones), leading to major health problems including vision damage.

How is Tepezza Administered?

Tepezza is delivered through an injection.

Tepezza infusions, completed by a healthcare provider, are given once every three weeks.

Eight total Tepezza infusions are prescribed for people suffering from Thyroid Eye Disease.

According to medical experts at Drugs.com:

The Tepezza dose is 10 milligrams per kilograms (mg/kg) for the first dose.

The following seven (7) doses are an IV infusion of 20 mg/kg given every three (3) weeks.

What are Tepezza’s Possible Side Effects?

According to the FDA, possible side effects of Tepezza include:

  • Infusion reactions
  • Worsening of inflammatory bowel disease
  • High blood sugar
  • Muscle spasms
  • Hair loss
  • Diarrhea
  • Fatigue
  • Dry skin
  • Change in taste
  • Headache

Outside of the listed side effects, there are potential hearing loss and tinnitus related side effects associated with the Thyroid Eye Disease drug.

Studies Show Potentially Permanent Hearing Damage in Tepezza Users

Research studies have found that a shocking percentage of patients who received Tepezza infusions suffered from hearing loss, tinnitus and other hearing problems.

Initial studies found that hearing related side effects only impacted around 10% of those who received Tepezza infusions.

In more recent studies, such as one published by the Endocrine Society, up to 65% of patients experienced hearing loss or hearing problems.

The hearing problems suffered by Tepezza patients are serious:

“Of the 17 patients with new hearing symptoms, four had new or worsening sensorineural hearing loss, a type of hearing loss resulting 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. Normally, these eustachian tubes remain closed and open only occasionally to regulate air pressure around the ear drum. After three months, symptoms of patulous eustachian tube improved, but did not completely disappear. Two patients with sensorineural hearing loss had improvement in symptoms at one and six months.”
