Detailed Description
-----------------
This is a multicenter, prospective, post-marketing clinical study with a total of 60 uveitis (UV) subjects planned to be enrolled. Screening period (-2 0 weeks) : the inclusion and exclusion criteria were evaluated, and those meeting the criteria could enter the treatment period. Treatment period (1-22 weeks) : Eligible subjects with non-infectious uveitis were given an initial subcutaneous injection of 80 mg at week 1, followed by a subcutaneous injection of 40 mg of Glorio (adamuzumab injection) every other week from week 1 to week 22 (a total of 12 doses). Follow-up period: Follow-up for safety and/or efficacy is recommended at 6, 12, 24, and 32 weeks after initiation of the study drug. A final visit will be made at 32 weeks. During the study, if the condition of the subjects or their symptoms and signs become worse, the investigator can adjust the use of drugs for uveitis other than study drugs according to the actual situation of the subjects. At the same time, plasma concentration will be determined before D1, D78 (week 12), and D162 (week 24); Immunogenicity analysis was performed before D1 administration, before D78 (week 12), before D162 (week 24) and before D218 (week 32)

Having any of the following general conditions: Subjects meet any of the following criteria associated with latent or active tuberculosis (TB) infection: . A history of active TB ≤ 3 years before screening (but can also be included if it is > 3 years and documented completion of adequate treatment); B. Signs or symptoms suggestive of active TB at the time of screening in the history and/or physical examination; C. Recent close contact with someone with active TB; D. If a TB infection T-cell test is positive at the time of screening, subjects will be excluded from the study if their first TB infection T-cell test is inconclusive. For suitable standards has been completed before screening latent TB treatment and no other risk factors, imaging findings, or support the latent or signs of active TB specific subjects, for positive or uncertain results may be the exception handling, researchers with the qualified physician judgment, tuberculosis (including extrapulmonary) risk, decision and discuss with bidders; Positive hepatitis C antibody during screening; Or HIV antibody positive; Or treponema pallidum antibody positive; Symptoms of severe, progressive or uncontrollable kidney, liver, blood, gastrointestinal, lung, cardiovascular, neurological or brain disease. The investigator felt that participating in the study placed patients at unacceptable risk. Patients with malignant tumors. Patients with moderate to severe heart failure (New York Heart Society Grades 3-4). History of severe allergy or anaphylactoid reaction to monoclonal antibodies. Prior treatment with anti-TUMOR necrosis factor TNF or other biological agents with potential therapeutic effect for uveitis (excluding intravitreal anti-VEGF drugs). During the 30 days prior to baseline, the combined dose of other immunosuppressant therapy increased or did not meet any of the following conditions: methotrexate MTX≤25mg/ week; Cyclosporine ≤4 mg/kg/ day; Mycophenolate (or equivalent dose of mycophenolate) ≤2g/ day; Azathioprine ≤175 mg/ day; Tacrolimus oral ≤8 mg/ day. Received clinical trial drug intervention within 3 months prior to screening. Received any live vaccine within 3 months prior to receiving the first dose of the study drug, or planned to receive live vaccine during the study period. There are contraindications to dilatation drugs. Patients judged unsuitable for inclusion by other investigators
