The Tepezza Litigation at a Glance

Tepezza (teprotumumab-trbw) is an FDA-approved infusion medication marketed for thyroid eye disease (TED) since 2020. Plaintiffs allege Horizon Therapeutics (acquired by Amgen in 2023) failed to adequately warn about the risk of permanent hearing loss, tinnitus, and other auditory injuries associated with treatment.

MDL 3079 Formation and Status

The JPML consolidated federal Tepezza cases in MDL 3079 in the Northern District of Illinois before Judge Thomas M. Durkin in June 2023. As of 2026:

  • Thousands of cases consolidated.
  • Bellwether selection and trials advancing.
  • Case-specific discovery underway.

Alleged Failure to Warn

Plaintiffs allege that clinical trial data and post-market surveillance showed meaningful hearing-related adverse events, but the original label understated the frequency and permanence of these injuries. Some warnings have been strengthened over time under FDA pressure.

Common Injuries

  • Permanent sensorineural hearing loss.
  • Tinnitus (ringing in the ears).
  • Autophony (hearing one's own voice too loudly).
  • Vestibular disturbance.

Documentation for a Case

  • Confirmed Tepezza use with treatment records.
  • Audiology testing before, during, and after treatment.
  • Documented persistent hearing loss or tinnitus.
  • MDL-experienced counsel.

Funding Availability

Pre-settlement funding is available for filed MDL cases with documented Tepezza use and audiology-confirmed hearing injury.

The Bottom Line

The Tepezza MDL is an active pharmaceutical mass tort with growing case numbers. If you took Tepezza and developed hearing loss or tinnitus, consult an MDL-experienced attorney and obtain audiology testing to document the injury.
