MHB018A Treatment in Patients With Active Thyroid Eye Disease

The primary objective of this study is to investigate the efficacy, safety, and tolerability of MHB018A, a humanized anti-IGF1R antibody, administered q4W for 6 months, in comparison to placebo, in the treatment of participants suffering from active TED.

Eye Tracking Study on Eye Movement Function and Visual Attention Patterns in Patients With Thyroid-Associated Ophthalmopathy

This study focuses on eye health and visual function in patients with Thyroid-Associated Ophthalmopathy (TAO), a condition that often causes bulging eyes and restricted eye movement. The purpose of this study is to use non-invasive eye-tracking technology to evaluate how the disease affects eye movement function. The investigators hypothesize that compared to healthy individuals, patients with TAO will show measurable differences in eye stability and the ability to track moving objects. Additionally, the investigators believe the disease may alter how patients visually scan faces (e.g., avoiding eye contact). The study will enroll 100 participants, including both patients and healthy volunteers. By recording gaze patterns while participants look at a screen, the investigators aim to objectively quantify the physical and social impact of the disease, providing better data for future treatment plans.

Evaluation of the Efficacy and Safety Observation of IBI311 Treatment in Patients With Inactive TAO

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. 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 IBI311 in inactive moderate to severe TAO patients. The aim of this clinical study is to: 1. To evaluate the efficacy of IBI311 treatment in patients with inactive moderate to severe TAO. 2. To observe the safety of IBI311 treatment in patients with inactive moderate to severe TAO.

Efficacy and Safety of Sequential Hormone Therapy and Tetuzumab Therapy in Patients With Moderate to Severe TAO in the Active Stage After Glucocorticoid Treatment.

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.

The Safety and Efficacy of Sequential Hormone Therapy and IBI311 Therapy in Patients With Active Moderate to Severe TAO in the Initial Treatment.

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: the lack of head-to-head studies of temumab and glucocorticoids. The aim of this clinical study is to: 1. To evaluate the efficacy of IBI311 treatment in patients with active moderate to severe TAO in the initial treatment. 2. To observe the safety of IBI311 treatment in patients with active moderate to severe TAO in the initial treatment. 3. Head-to-head comparison of sequential hormone therapy and IBI311 therapy in patients with active moderate to severe TAO in the initial treatment.
