Thyroid Eye Disease

The primary objective of Part A of this study is to investigate the safety and tolerability of AMG 732 after single subcutaneous (SC) doses. The primary objective of Part B of this study is to investigate the efficacy of AMG 732 in participants with Thyroid Eye Disease (TED) after multiple SC doses.

The main objective of this trial is to assess the efficacy of AMG 732 in participants with thyroid eye disease (TED) who are defined as primary nonresponders or relapsed during the safety follow-up in the parent trial (NCT06401044).

This prospective, multicenter, multinational observational study evaluates the clinical validity of an AI-based quantitative eye movement analysis system (Glandy EOM) that analyzes smartphone-recorded 9-gaze videos. Approximately 200 adults per site with suspected or confirmed ocular motility abnormalities will undergo a single study visit consisting of a standard clinical 9-gaze examination, an assistant-aided smartphone video recording, and a patient self-recorded video acquisition using a mobile application. Because the study population is defined by clinical suspicion or diagnosis of ocular motility abnormality rather than confirmed disease at enrollment, some participants may be clinically judged to have no abnormality on formal evaluation; such subjects remain part of the study population and are not considered healthy volunteers. AI-derived quantitative eye movement metrics (corneal center displacement in millimeters and angular deviation) will be compared with rater-derived measurements obtained from the same videos using a calibrated reference approach, and with clinician-assessed 9-gaze grading. The investigational device is used solely for video acquisition and analysis and does not influence clinical decision-making.

This is a multicenter, randomized, double-masked, placebo-controlled, single/multiple-dose-escalation trial conducted in Chinese participants with Thyroid Eye Disease (TED), aiming to evaluate the safety and tolerability of IBI3031 administered via subcutaneous or intravenous injection.

This is a pilot study to investigate serum prednisolone profiles in: * Patients on high doses of prednisolone for any inflammatory disorder, both in the acute and chronic setting. * Patients stepping up from or down to prednisolone therapy in association with a course of high dose methyl-prednisolone or dexamethasone. The study will comprise 3 groups, including those started on high doses of prednisolone acutely in an inpatient or outpatient setting, participants on chronically high doses, and those receiving a several week course of high dose methylprednisolone or dexamethasone. The study aims to measure prednisolone levels at a number of time points to investigate serum profile differences in those receiving prednisolone acutely compared with longer term steroid use. Further samples will be taken to characterise additional metabolic changes.

Multicentre, Phase Ib/II Clinical Study to Evaluate the Safety, Pharmacokinetics, Pharmacodynamics, and Efficacy of NTB003 in Participants with Thyroid Eye Disease

This is a prospective study designed to evaluate the efficacy and safety of Teprotumumab N01 in patients with Thyroid Eye Disease (TED). Eligible patients will receive Teprotumumab N01 and will be assessed using clinical and imaging parameters before and after treatment, with each patient serving as their own control. The primary endpoint is the overall response rate at Week 24.

The goal of this interventional study is to compare the clinical outcomes of shortened 4-infusion course versus the standard 8-infusion course of Teprotumumab (Tepezza) in patients with active Thyroid Eye Disease (TED). The main question it aims to answer is: \* Is a shorter course equally effective and safe for patients who respond well early in treatment. Participants who demonstrate an early clinical response as part of their treatment with Teprotumumab will receive a shorter protocol of 4 infusions instead of the standard 8.

This is a multicenter, randomized, open-label, active-controlled Phase IV clinical trial in participants with active thyroid eye disease (TED). Approximately 92 eligible participants will be randomized to the teprotumumab N01 group and the intravenous glucocorticoid (IVGC) group in a 1:1 ratio on Day 1. The randomization stratification factor is diplopia at baseline (Gorman diplopia score ≥1 vs. Gorman diplopia score = 0).

A multicenter clinical study to evaluate the efficacy and safety of IBI311 in subjects with inactive thyroid eye disease. The study consists of two parts, with a maximum duration of approximately 64 weeks.

The overall study objective is to continue to assess the efficacy, safety, pharmacokinetics, and pharmacodynamics of linsitinib in subjects who were enrolled in the prior VGN-TED-301 through Week 24. These subjects include VGN-TED-301 Week 24 proptosis non-responders or subjects who relapse during the Follow-Up Period of VGN-TED-301.

FAPI PET has been developed as a promising approach for the evaluation of fibroinflammatory, such as in inflammatory bowel disease. This prospective study aims to explore the value of 18F-AlF-FAPI PET/CT in assessing the activity of Thyroid Eye Disease (TED) and investigate whether FAPI PET/CT may be superior to 99mTc-DTPA SPECT/CT for the diagnosis, therapy response assessment, and follow-up of TED.

This protocol studies the clinical outcome of patients with active thyroid disease with visually significant signs and symptoms of proptosis, pain, diplopiam lid/orbital edema, or lid/orbital erythema recommended for treatment with teprotumumab infusion (Tepezza®). Patients recommended for treatment will be evaluated by an oculoplastic surgeon (Dr. Eva Chou) and endocrinologist (Dr. Thanh Hoang).
