Design outcomes

Primary

MeasureTime frameDescription
Responder Status at Week 12Week 12This end point main evaluation improvement of clinical activity score and proptosis at week 12. A reduction of the CAS 2 point or more, and reduction of the proptosis 2 mm or more was defined as response.

Secondary

MeasureTime frameDescription
Overall Average Continuous Change in Proptosis From Baseline to Week 24Baseline to Week 24Proptosis is the amount of protrusion of the eye from the orbital rim. Measurements were recorded with the Hertel exophthalmometer.
Overall Average Change in Diplopia grading From Baseline to Week 24Baseline to Week 24Diplopia grading included 01/4no:no diplopia; 11/4intermittent: diplopia in primary position of gaze, when tired or when first awakening; 21/4inconstant: diplopia at extremes of gaze; 31/4constant: continuous diplopia in primary or reading position). Diplopia change in one grade or more at week 24 was regarded as improvement.
Overall Average Change in extra-ocular muscular thickening From Baseline in thickening extra-ocular muscular improvement in Orbital CT to Week 24Baseline to Week 24Observation of extra-ocular muscular thickening is observed on Orbital CT. One or more extra-ocular muscle recovery at week 24 was regarded as improvemed.
Overall Average Continuous Change in CAS From Baseline to Week 24Baseline to Week 24The 7-item European Group on Graves' Ophthalmopathy (EUGOGO) amended CAS was used to evaluate clinical activity. CAS of 3 point or more on a 7-point scale indicating active thyroid-associated ophthalmopathy.
Overall Average Change in GO-QOLScale - Visual Functioning From baseline to Week 24 follow-upBaseline to Week 24Transformed Visual Functioning score is the sum of scores from following 8 questions to a scale of 0 (worst health) to 50 (best health): bicycling, driving, moving around the house, walking outdoors, reading, watching television (TV), hobby or pastime, feel hindered.
Overall Average Change in GO-QOLScale - Appearance From baseline to Week 24 follow-upBaseline to Week 24Transformed Appearance score is the sum of scores from the following 8 questions to a scale of 0 (worst health) to 50 (best health): feel appearance has changed, feel being stared at, feel people react unpleasantly, influence on self-confidence, feel socially isolated, influence on making friends, appear less often on photos, try to mask changes in appearance.
Overall Average Change in Graves' Ophthalmopathy Quality of Life (GO-QOL) Scale From baseline to Week 24 follow-upBaseline to Week 24The GO-QOL is a 16-item self-administered questionnaire used to assess the perceived effects of thyroid associated ophthalmopathy (TAO) by the participants on their daily physical and psychosocial functioning. Two subscales of the 16-question GO-QOL have been defined: Visual Functioning and Appearance, with 8 questions comprising each subscale.The transformed overall score is the sum of scores from all 16 questions to a scale of 0 (worst health) to 100 (best health). A change of 8 point was defined as improvement.
