Primary Outcome Measures
NameTimeMethod
Percentage of proptosis respondersAt Week 24

Proptosis is the amount of protrusion of the eye from the orbital rim. Measurements are recorded using the Hertel exophthalmometer. The study eye is defined as the most severely affected eye at the Baseline visit. Proptosis responder is defined as the participant with a greater than or equal to (≥) 2 millimeters (mm) reduction in the study eye without deterioration (≥2 mm increase) in the fellow eye.

Secondary Outcome Measures
NameTimeMethod
Percentage of participants with CAS of 0 or 1 in the study eyeAt Week 24
Percentage of participants with positive binding anti-thyroid stimulating hormone receptor (TSHR) antibody (Ab) at Baseline who achieve seroconversionBaseline and Week 24
Percentage of participants with decrease of at least 1 grade from Baseline in Gorman score for diplopiaBaseline and Week 24

Diplopia will be assessed based on 3 grades: Grade I - Intermittent diplopia (diplopia in primary position of gaze, when tired or when first awakening), Grade II - Inconstant diplopia (diplopia at extremes of gaze) and Grade III - Constant diplopia (continuous diplopia in primary or reading position). Higher scores indicate worse symptoms.

Mean change from Baseline in proptosis in the study eyeBaseline and Week 24
Percentage of participants with proptosis ≥2 mm reduction and Clinical Activity Score (CAS) of less than or equal to (≤) 3 from Baseline in the study eyeBaseline and Week 24

The CAS measures the classical signs of acute inflammation (pain, redness, and swelling) in TED. The 7-item scale assigns 1 point for the presence of each of the parameters assessed: spontaneous retrobulbar pain, pain on attempted upward or downward gaze, redness of eyelids, redness of conjunctiva, swelling of caruncle or plica, swelling of eyelids, swelling of conjunctiva (chemosis). The sum of these points is the total score, with 0 indicating no clinical activity and 7 indicating the most severe clinical activity. Higher scores indicate worse symptoms.

Mean change from Baseline in CAS in the study eyeBaseline and Week 24
Percentage of participants with ≥6-point increase from Baseline in total Graves' ophthalmopathy - Quality of life (GO-QOL) scoreBaseline and Week 24

The GO-QOL is a 16-item self-administered questionnaire designed to assess how GO affects different aspects related to quality of life (visual functioning and psychosocial consequences). The points given to questions 1 to 8 and 9 to 16 are added to obtain 2 raw scores ranging from 8 to 24; one for visual functioning and one for appearance. Higher scores indicate better outcome.

Percentage of participants with ≥8-degree increase from Baseline in motility (in at least 1 of 4 directions) in the study eyeBaseline and Week 24
