Tepezza Lawsuit 2026, No Settlement Yet, All Trials Canceled—273 Cases Signal Horizon May Settle Hearing Loss Claims After Judge Removes Trial Dates
The Tepezza lawsuit showed no change in the total number of multidistrict litigation cases from December 2025 to January 2026, holding steady at 273 total cases, but the bigger story is what’s missing from the docket. In October 2025, the federal judge overseeing the Tepezza hearing loss multidistrict litigation has removed all upcoming deadlines for bellwether trials, prompting speculation that Horizon Therapeutics may be nearing a global settlement.
As of February 2026, no settlement exists. But the sudden cancellation of trials that were scheduled to start June 2026 suggests Horizon may be preparing significant offers to resolve claims that its thyroid eye disease drug caused permanent hearing damage without proper warnings.
What Is the Tepezza Lawsuit About?
Plaintiffs allege that the drug’s labeling failed to adequately warn about the risk of permanent auditory damage associated with Tepezza treatment. The drug was approved by FDA in January 2020 to treat thyroid eye disease, but Horizon did not add warnings about these risks until July 2023, years after evidence first emerged.
More than 270 federal lawsuits are consolidated before U.S. District Judge Thomas Durkin in the Northern District of Illinois. Patients claim they suffered permanent hearing loss, tinnitus, and related auditory damage after receiving Tepezza infusions—injuries Horizon allegedly knew about but concealed.
Why Did All Trial Dates Get Canceled?
According to a docket entry dated October 1, Chief Magistrate Judge M. David Weisman held an off-the-record discussion with both parties’ counsel and subsequently struck all existing bellwether deadlines. The four representative cases that were supposed to go to trial in June 2026 were abruptly removed from the calendar.
The Court’s decision follows nearly a year of required settlement discussions held every three months under Judge Durkin’s direction. In mass torts, canceling scheduled trials usually signals one thing: the parties are close to a deal.
Current Status: Settlement Talks But No Agreement Yet
The Court has scheduled the next status conference for January 8, 2026, which has since passed. As of mid-February 2026, no settlement has been announced and no claim forms are available.
However, the litigation pattern mirrors other pharmaceutical cases like the Vioxx Lawsuit Scandal Merck Paid $4.85 Billion After Hiding Heart Attack Risks From Millions, where bellwether trial cancellations preceded global settlements.
Who Qualifies for a Tepezza Lawsuit?
You may be eligible if you received Tepezza infusions for thyroid eye disease and subsequently experienced permanent hearing loss, severe tinnitus, muffled hearing, difficulty understanding speech, balance problems, or need hearing aids due to auditory damage.
Critically, if your treatment occurred before July 2023, the drug label contained no hearing loss warnings, which were only added in July 2023. This timing strengthens your claim that Horizon failed to provide adequate warnings.
What Compensation Might Be Available?
While no settlement exists, attorney estimates provide some guidance. The average Tepezza settlement per person is estimated to range between $75,000 to $200,000 or more, depending on the severity of hearing loss, medical documentation, and the strength of causation evidence.
Cases are likely to be tiered based on injury severity:
Tier 1 (permanent, total hearing loss): Potentially $175,000 to $200,000 or more
Tier 2 (severe ongoing hearing impairment requiring hearing aids): Estimated $100,000-$175,000
Tier 3 (temporary or mild hearing damage): Potentially ranging from $50,000 to $100,000
These are projections only. Actual settlement amounts depend on Horizon’s offers and individual case strength.
What Documentation Do You Need?
Gather all medical records showing Tepezza infusion dates and dosages, audiology test results before and after treatment, hearing aid prescriptions or cochlear implant records, doctor notes documenting hearing complaints during or after Tepezza, and pharmacy records confirming Tepezza treatments.
The stronger your medical documentation linking Tepezza to your hearing loss, the higher your potential compensation.
How to Monitor This Lawsuit
As of January 2026, there are 273 cases pending, with 282 total cases. The MDL remains relatively small compared to other pharmaceutical litigations, which may actually speed settlement negotiations.
Horizon faces quarterly settlement conferences ordered by the court. If talks fail, expect bellwether trials to be rescheduled for late 2026 or 2027.
What Should You Do Now?
If you took Tepezza and developed hearing problems: Contact a mass tort attorney immediately. Statutes of limitations typically run 2-3 years from injury discovery, but some states have shorter deadlines.
Document everything: Request copies of all medical records related to your Tepezza treatment and hearing issues. Get audiologist evaluations documenting the extent of your hearing loss.
Don’t wait for settlement announcement: Cases must be filed before settlement negotiations conclude. Waiting until a settlement is announced may leave you excluded.

How long do I have to file a lawsuit?
State statutes of limitations for product liability range from 2-3 years from when you discovered your injury. Consult an attorney immediately to protect your rights.
