简要总结
A multicenter, open-label extension study evaluating the efficacy and safety of IBI311 in subjects with thyroid eye disease
详细描述
This is a multicenter, open-label outreach study. Participants who have previously participated in and completed CIBI311A201 double-blind treatment can enter this study after signing informed consent. The study included an observation period and an open treatment period. Observation period: From weeks D0 to 24, all subjects will return to the research center every 8 weeks for disease evaluation. If the investigator determines that treatment is required based on predefined criteria, they will enter the open treatment period to receive IBI311 treatment; Otherwise, subjects will continue to be visited every 8 weeks until week 24. Open Treatment period: Subjects entering the open treatment period will receive 8 infusions of IBI311 (initial dose of 10 mg/kg, followed by 7 maintenance doses of 20 mg/kg, Q3W.

排除标准
- •Visual dysfunction due to optic neuropathy, defined as a decrease of ≥2 lines of best corrected vision within the last 180 days, a new visual field defect, or color difference secondary to optic nerve involvementOften;
- •Patients with corneal ulcers that the investigator determined did not resolve after treatment;
- •When the FU1 visit predecessor was scheduled to receive orbital radiation therapy or surgery for TED, including orbital decompression, strabismus correction, and eyelid correction, or during the study periodEtc.;
- •Poor thyroid function control was defined as free T3 or T4 deviating from the normal reference range of the local research center laboratory by more than 50% during FU1 visit;
- •The presence of any other prior disease, metabolic disorder, abnormal results of physical examination or clinical laboratory examination, which may reasonably be suspected to cause contraindications in the use of the test drug, or shadow Diseases or conditions that place subjects at high risk for treatment complications, including, but not limited to, confirmed or clinically suspected inflammatory bowel disease and coagulation Blood dysfunction, history of acute cardiovascular and cerebrovascular disease or treatment within 180 days prior to FU1 visit (including but not limited to: cerebrovascular accident, transient cerebral ischemia, acute myocardial infarction) Death, unstable angina pectoris, coronary artery bypass grafting, percutaneous coronary intervention (except diagnostic angiography), severe arrhythmia, etc.), treatment within the past 5 years or A history of untreated malignancy (squamous cell carcinoma of the skin, basal cell carcinoma, carcinoma in situ of the cervix, prostate in situ, or thyroid that has been successfully resected without evidence of metastasis) Other than papillary carcinoma), serious systemic infection, non-TED caused eye protrusion, etc.;
- •At the time of FU1 visit, either ear was present: a history of tinnitus or other hearing impairment; Or abnormal pure tone audiometry (defined as 0.5 1 24 4 kHz mean bone conduction threshold ≥25 dB or either Bone conduction threshold under frequency ≥40 dB);
