Plain-language summary
Thyroid-associated ophthalmopathy (TAO) is an organ-specific autoimmune disease closely related to thyroid disease, which leads the incidence of orbital disease in adults and is the most common cause of diffuse toxic goiter (Graves disease, GD). The clinical manifestations of TAO are complex and varied. In severe cases, it may seriously impair visual function, affect daily life, and even cause corneal ulceration, perforation, and blindness. Therefore, a reasonable and effective treatment plan should be chosen according to the degree of TAO. Tetuzumab (IBI311) is a fully human monoclonal insulin-like growth factor-1 receptor inhibitory antibody. It has binding activity against IGF-1R positive cells, can block the binding of IGF-1 and IGF-2 to IGF-1R, and has a dose-dependent effect. It can inhibit the proliferation of HT29 cells caused by the activation of the IGF-1R signaling pathway. Meanwhile, it can dose-dependently inhibit the proliferation of orbital fibroblasts and the secretion of hyaluronic acid (HA) in patients with TAO.
However, there are still significant gaps in the existing research evidence: There is a lack of reports on the efficacy and safety of Tetuzumab (IBI311) in the population after glucocorticoid treatment.
The aim of this clinical study is to:
1. To evaluate the efficacy of IBI311 treatment in patients with active moderate to severe TAO after glucocorticoid treatment.
2. To observe the safety of IBI311 treatment in patients with active moderate to severe TAO after glucocorticoid treatment.

Inclusion Criteria:
* Inclusion Criteria:
* Diagnosed with TAO by Bartley criteria.
* Moderate to severe patients defined by EUGOGO.
* CAS ≥4 (on the 7-item scale) for the study eye.
* participants have received glucocorticoid treatment for TAO in the past，but did not responsive or has an unsatisfactory effect.
Exclusion Criteria:
* Anticipated need for intervention due to sight-threatening complications or other significant and acute deterioration in vision.
* Combined with other lesions in the orbit.
* Receive orbital radiotherapy or surgical treatment for TED, including orbital decompression, strabismus surgery and eyelid retraction correction.
* During the screening period, if either ear has a history of tinnitus or other hearing impairment; Or abnormal pure tone audiometry results (defined as an average bone conduction hearing threshold of ≥25 dB at 0.5, 1, 2, 4 kHz or a bone conduction hearing threshold of ≥40 dB at any frequency).
* At the time of screening, aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \> 3 times ULN, or accompanied by active hepatitis B (defined as HBsAg positive with HBV-DNA load greater than 1000 IU/mL), or being receiving anti-hepatitis B virus treatment.
* During screening, the Glomerular Filtration Rate (GFR) was \< 30 ml/min/1.73m2 (using the MDRD formula: GFR =186× serum creatinine (mg/dl) -1.154× (age) -0.203× (0.742 \[if female\]), unit conversion of serum creatinine: 1 μmol/L=0.0113 mg/dL); 10) At the time of screeni…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
