Detailed Description
This is a randomized, double-masked, placebo-controlled, parallel-group, multicenter study. Approximately 76 participants (38/group) who meet the study eligibility criteria will be randomized on Day 1 in a 1:1 ratio (stratified by tobacco use status) to receive 8 infusions of teprotumumab or placebo q3W. All participants will enter a 24-week double-masked Treatment Period, during which study drug will be infused on Day 1 (Baseline), and Weeks 3, 6, 9, 12, 15, 18, and 21 (with a final visit at Week 24). All study drug dosing will be performed at the clinic under the supervision of clinic staff. On each dosing day, scheduled assessments (except for adverse event [AE] and concomitant medication use monitoring, which will be monitored throughout the clinic visit) will be completed prior to study drug dosing.
At the end of the double-masked Treatment Period (Week 24), participants who are proptosis non-responders (study eye has < 2 mm decrease in proptosis) will be eligible to enter an open-label extension study in which participants receive 8 infusions of teprotumumab in an open-label fashion.
At Week 24, proptosis responders, as well as non-responders who choose not to enroll in the open-label extension study, will enter a 48-week Follow-Up Period, during which study drug will not be administered and clinic visits are scheduled for Weeks 28, 36, 48, 60, and 72. Participants who are considered responders at Week 24 but who meet criteria for re-treatment due to relapse during the Follow-Up Period may enroll in the open-label extension study.
Participants who complete the Week 72 Visit will be contacted 6 and 12 months later via phone or email by research staff to enquire if any treatment for TED has been received since last study contact.

- Any previous treatment with rituximab or tocilizumab. Use of any other non-steroid immunosuppressive agent within 3 months prior to Screening.
- Use of an investigational agent for any condition within 60 days prior to Screening or anticipated use during the course of the trial.
- Identified pre-existing ophthalmic disease that, in the judgment of the Investigator, would preclude study participation or complicate interpretation of study results.
- Bleeding diathesis that in the judgment of the Investigator would preclude inclusion in the clinical trial.
- Malignant condition in the past 12 months (except successfully treated basal/squamous cell carcinoma of the skin).
- Pregnant or lactating women.
- Current drug or alcohol abuse, or history of either within the previous 2 years, in the opinion of the Investigator or as reported by the participant.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Who Were Overall Responders at Week 24
Time Frame: Week 24
|
Overall responders were defined as participants with a ≥2 mm reduction in proptosis AND a ≥2 point reduction in Clinical Activity Score (CAS) from Baseline in the study eye, without deterioration (≥2 mm increase in proptosis or ≥2 point increase in CAS) in the fellow eye at Week 24. The CAS is a 7-item description of clinical activity, including: 1. Spontaneous orbital pain; 2. Gaze evoked orbital pain; 3. Eyelid swelling that is considered to be due to active (inflammatory phase) thyroid eye disease/ Graves' Ophthalmopathy or Orbitopathy (TED/GO); 4. Eyelid erythema; 5. Conjunctival redness that is considered to be due to active (inflammatory phase) TED/GO (ignore "equivocal" redness); 6. Chemosis; 7. Inflammation of caruncle or plica. Each item is scored (1=present; 0=absent) and scores for each item are summed for total score of 0 (no clinical activity) to 7 (most clinical activity). |
Week 24
|
Percentage of Participants Who Were CAS Categorical Responders at Week 24 (Study Eye)
Time Frame: Week 24
|
CAS categorical responders were defined as participants with a reduction to a CAS of 0 or 1 (no or minimal inflammatory symptoms) in study eye. The CAS is a 7-item description of clinical activity, including: 1. Spontaneous orbital pain; 2. Gaze evoked orbital pain; 3. Eyelid swelling that is considered to be due to active (inflammatory phase) thyroid eye disease/ Graves' Ophthalmopathy or Orbitopathy (TED/GO); 4. Eyelid erythema; 5. Conjunctival redness that is considered to be due to active (inflammatory phase) TED/GO (ignore "equivocal" redness); 6. Chemosis; 7. Inflammation of caruncle or plica. Each item is scored (1=present; 0=absent) and scores for each item are summed for total score of 0 (no inflammatory symptoms) to 7 (most inflammatory symptoms). |
Week 24

Change From Baseline in Proptosis to Week 24 (Study Eye)
Time Frame: Baseline, up to Week 24
|
Baseline, up to Week 24
|
|
Percentage of Participants Who Were Diplopia Responders at Week 24
Time Frame: Week 24
|
Diplopia responders were defined as participants with Baseline diplopia Subjective Diplopia Score grade >0 in the study eye who had a reduction of ≥1 grade with no corresponding deterioration (≥1 grade worsening) in the fellow eye at Week 24. Denominator is the number of subjects with diplopia at Baseline. The Subjective Diplopia Score is a clinical measure of diplopia severity on a grade scale of 0 to 3: 0=no diplopia; 1=intermittent (diplopia in primary position of gaze, when tired or when first awakening); 2=inconstant (diplopia at extremes of gaze); 3=constant (continuous diplopia in primary or reading position). |
Week 24
|
Change From Baseline in the Graves' Ophthalmopathy Quality of Life (GO-QoL) Questionnaire Overall Score to Week 24
Time Frame: Baseline, up to Week 24
|
The GO-QoL is a 16-item self-administered questionnaire divided into 2 subsets and used to assess the perceived effects of TED by the subjects on (i) their daily physical activity as it relates to visual function, and (ii) psychosocial functioning.
The range of the GO-QoL overall transformed scores is 0 to 100, where higher values correspond to better quality of life.
