New real-world analysis of Tepezza use indicates a small percentage of people receive a second course of treatment for thyroid eye disease

Evidence has indicated that due to the progressive nature of TED, the disease may reactivate, or flare. In a retrospective chart review, up to 15% of patients experienced a TED flare, regardless of treatment regimen. While many causes for reactivation are unknown, some triggers include pregnancy, stress and surgery.

The real-world analysis assessed deidentified claims data from people living with TED who completed a full, uninterrupted course of Tepezza (8 infusions) in 2020 and then subsequently were prescribed a second course of treatment prior to July 2022. During this two-year period, 4.9% (286/5,845) of patients were prescribed a second course of Tepezza. 1.9% (110/5,845) of the total patients went on to initiate treatment by the end of the two-year period, with a mean time of 12 months between courses.

“Treating an autoimmune condition like Thyroid Eye Disease that may worsen or flare over time is challenging,” said Shoaib Ugradar, M.D., The Jules Stein Eye Institute at University of California, Los Angeles (UCLA). “These data indicate that the need is low for additional treatment with Tepezza for those living with Thyroid Eye Disease who have completed an initial course. With continued analysis and research, we hope to come closer to identifying specific causes and indicators for additional treatment in order to better manage this debilitating, life-long condition.”

Horizon also announced results from a 2018 U.S. survey of endocrinologist and ophthalmologists comparing the impact of shorter versus longer duration TED in patients with a high Clinical Activity Score (CAS). The analysis looked at those with a CAS greater than 3, who had lived with TED for less than or equal to three years (n=192) versus over three years (n=115). Both shorter and longer duration groups reported comparable overall negative mental health impact (38.5% vs. 35.7%, respectively) and experience with anxiety and depression. They both also reported a similar negative effect of TED on their quality of life, as measured by a seven-point Likert scale, including social and daily activities..
