the following at screening and Visit 0:

• A CAS = 4 in either eye, and
• Clinical evidence of worsened proptosis with:

4. Have onset of active TED within 12 months prior to screening.

5. Have documented evidence of detectable anti-TSHR-Ab at screening.

6. Are not expected to require immediate surgical intervention and are not planning corrective surgery/irradiation or medical therapy for TED during the course of the study.

7. Are euthyroid with the Baseline disease under control or have mild hypo- or hyperthyroidism. Additional inclusion criteria are defined in the protocol.

Exclusion criteria:

1. Have decreased best corrected visual acuity due to optic neuropathy.

2. Have at least a 2-point decrease in CAS or =2 mm decrease in proptosis between screening and Baseline assessments in either eye.

3. Have used any steroid (intravenous or oral) for the treatment of TED or other conditions within 4 weeks prior to screening.

4. Have used any steroid (Intravenous or oral) with a cumulative dose equivalent to = 1 g of methylprednisolone for the treatment of TED.

5. Have known autoimmune disease other than TED, that, in the opinion of the Investigator, would interfere with the course and conduct of the study.

6. Had previous orbital irradiation or surgery for TED. Additional exclusion criteria are defined in the protocol.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of proptosis responders	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.	At Week 24
Secondary	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 eye	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.	Baseline and Week 24
Secondary	Percentage of participants with CAS of 0 or 1 in the study eye		At Week 24
Secondary	Mean change from Baseline in CAS in the study eye		Baseline and Week 24
Secondary	Percentage of participants with positive binding anti-thyroid stimulating hormone receptor (TSHR) antibody (Ab) at Baseline who achieve seroconversion		Baseline and Week 24
Secondary	Percentage of participants with decrease of at least 1 grade from Baseline in Gorman score for diplopia	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.	Baseline and Week 24
Secondary	Mean change from Baseline in proptosis in the study eye		Baseline and Week 24
Secondary	Percentage of participants with =6-point increase from Baseline in total Graves' ophthalmopathy - Quality of life (GO-QOL) score	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.	Baseline and Week 24
Secondary	Percentage of participants with =8-degree increase from Baseline in motility (in at least 1 of 4 directions) in the study eye		Baseline and Week 24
