Though the manufacturer has yet to fully describe and characterize the molecular, biochemical, and physiologic actions through which Tepezza treats thyroid eye disease (TED), it is believed that the mechanism by which Tepezza causes hearing loss and other hearing-related health damage is a result of this drug inhibiting the insulin-like growth factor-1 and the insulin-like growth factor-1 receptor pathway. What does this mean?
Tepezza infusion treatment acts like an inhibitor medication for insulin-like growth factor 1 receptor (IGF-IR), which receptor is crucial to protecting inner ear hair cells from:
The Tepezza warning label draws attention to hearing loss as an adverse effect in about 10% of the patients, but it was later shown in a study by Stanford University researchers and presented at the 2021 annual meeting of the Endocrine Society that this risk is significantly higher, reaching up to 65%.
Horizon Pharmaceutics, the manufacturer of Tepezza, claimed that hearing loss symptoms that occur as an adverse effect of the Tepezza infusion treatment are reversible and will disappear in a period of around three months after the last dose of the infusion was administered.
The study of the Stanford University researchers has shown, however, that while some of the symptoms are indeed reversible, this is not true for all of them and for all cases. Some of the symptoms not only did not improve over time but remained permanent.
The most significant hearing-related health damages linked to the Tepezza infusion treatment are:
but other symptoms include:
