Abstract
PURPOSE: To describe the treatment of nine patients with chronic, low clinical activity score thyroid eye disease with teprotumumab. METHODS: A retrospective series of patients with chronic thyroid eye disease (TED) and low clinical activity score (CAS) treated with teprotumumab infusion therapy. Inclusion criteria: adults over 18 years of age with TED for greater than 9 months and CAS of 1 or less. All patients included in the analyses completed a full series of eight infusions. Primary outcome measures included proptosis and eyelid retraction in both eyes. Secondary outcomes included CAS, reported adverse effects, and surgery post-treatment. RESULTS: Nine patients met all inclusion criteria, seven females and two males with mean age of 50.2 years and TED diagnosis of 6.25 years. Three patients had a baseline CAS of 1 and 6 had a CAS of 0. Mean proptosis reduction in the worse eye was 4.0 ± 2.4 mm immediately post-treatment (p = .02). Five out of nine patients had extended follow-up (average 16.8 ± 5.1 weeks) with mean proptosis reduction of 4.2 ± 2.8 mm at last follow-up (p = .03). Mean reduction in eyelid retraction in the worse eye was 0.3 ± 1.6 mm post-treatment (p = .58) and 0.5 ± 0.9 mm at last follow-up (p = .30). Three patients reported infusion-related myalgias, two hair thinning, one exacerbated chronic tinnitus, and one hyperglycemia. CONCLUSIONS: We report clinically and statistically significant proptosis reduction in nine patients with chronic, low CAS TED treated with teprotumumab. Teprotumumab may be an effective treatment option for these patients.
