Clinical Trial Summary

The aim of this study is to evaluate the efficacy and safety of Tocilizumab as second/third line treatment in patients with Active Moderate-to-Severe Corticosteroid-Resistant Thyroid Eye Disease.


Description:

Graves' Orbitopathy (GO) is an autoimmune disease that involves orbital tissues, leading to temporary or permanent damage to the eye. Although GO is a rare condition, it negatively affects the quality of life in the majority of patients. In the majority of european centers, high-dose intravenous glucocorticoid (GCs) therapy remains the first-line treatment in patients with active, moderate-to-severe GO. However, GCs are effective in only 45-60% of patients, with a high probability of diseases relapse (10-40%) or disease progression to dysthyroid optic neuropathy (up to 10%). Due to limited efficacy of GCs, unpredictable relapses and progression of GO, the management of GO remains a challenge. A few studies have demonstrated that interleukin-6 (IL-6) blockade with tocilizumab (TCZ) is effective in GC-refractory GO. However, the long-term outcomes of TCZ remain scarce. Therefore, the investigators are planning to assess the therapy with Tocilizumab, regarding clinical outcomes and adverse events. The investigators plan to include a total of 30 patients with active, moderate-to-severe, corticosteroid-resistant GO over a period of approximately 4 years.

Primary Disease improvement Proportion of patients improved at 16, 24 and 48 weeks as assessed by a composite ophthalmic score. A response to treatment will be considered positive in the case of an improvement of at least 2 of the following features in 1 eye, without concomitant deterioration in the other eye:
decrease in eyelid aperture by at least 2 mm measured with a ruler
decrease in proptosis by at least 2 mm measured with Hertel Exophthalmometer
increase in eyelid motility by at least 8° assessed by ophthalmologist or improvement of Bahn-Gorman diplopia score (Grade I - intermittent diplopia, Grade II - Inconstant diplopia, Grade III - Constant diplopia)
