Clinical Trial Summary

This project is designed to test the hypothesis that adalimumab is clinically useful for patients with acuta Vogt-Koyanagi-Harada disease

Description:

Approval of the study was obtained from the hospital's ethical committee. The study design and methodology followed the tenets of Declaration of Helsinki. All patients were provided with written informed consent and received a thorough explanation of the use of adalimumab, its potential risks and benefits. This is a monocenter, cohort, observational study evaluating patients with acute VKH divided into two groups: adalimumab therapy group and traditional therapy group. For adalimumab therapy group, an initial dose of 80 mg adalimumab was administered subcutaneously followed by a maintenance dose of 40 mg every two weeks, and data will be collected prospectively with regard to ophthalmologic outcomes. For the traditional therapy group, patients were treated with glucocorticoids alone or glucocorticoids combined with immunosuppressants. Study participants will be followed for up to one year to determine efficacy and side effects. According to best corrected visual acuity (BCVA), anterior chamber and vitreous inflammation, optical coherence tomography (OCT), change in corticosteroid dose during the study period and so on. The investigators evaluate the anti-inflammatory and immunosuppressive effects of adalimumab in treatment of acute VKH.

2. Subject with corneal or lens opacity that precludes visualization of the fundus or that likely requires cataract surgery during the duration of the trial.

3. Subject has previous exposure to anti-tumor necrosis factor (TNF) therapy or any biologic therapy with a potential therapeutic impact on non-infectious uveitis.

4. Subject has received Ozurdex® (dexamethasone implant) within 6 months prior to the Baseline visit.

5. Subject has received intravitreal anti-VEGF therapy within 45 days of the Baseline visit for Lucentis® (ranibizumab) or Avastin® (bevacizumab) or within 60 days of the Baseline visit for anti-VEGF Trap (aflibercept).

6. Subject has received intravitreal methotrexate within 90 days prior to the Baseline visit.

• Uveomeningoencephalitic Syndrome
• Vogt-Koyanagi-Harada Disease

Intervention

Drug:
• Adalimumab
Adalimumab is administered subcutaneously at an initial loading dose of 80 mg, followed by a 40 mg dose every other week (q2w) starting from the second week. Therapy will be continued 6 months after the disappearance of active ocular inflammation. Then, injection will extend for 3 days until withdrawal after 40 days apart.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change In LogMAR Best Corrected Visual Acuity (BCVA) From Baseline to Each Visit.	The participant's best corrected visual acuity was measured using an Early Treatment Diabetic Retinopathy Study (ETDRS) logMAR chart. On the logMAR scale, 0 is equivalent to 20/20 visual acuity, the range of normal vision is considered to be from -0.2 - 0.1; higher values indicate visual impairment.	24 weeks
Primary	Recurrence rate	The recurrence rates in adalimumab treatment group and control group	24 weeks
Secondary	Change in Anterior Chamber (AC) Cell Grade From Baseline to Each Visit	Slit lamp examinations were conducted at each visit to assess AC cell count. The number of AC cells observed within a 1 mm × 1 mm slit beam was used to determine the grade according to the Standardization of Uveitis Nomenclature (SUN) criteria: Grade 0 = < 1 cell Grade 0.5+ = 1 - 5 cells Grade 1+ = 6 - 15 cells Grade 2+ = 16 - 25 cells Grade 3+ = 26 - 50 cells Grade 4+ = > 50 cells.	24 weeks
Secondary	Prednisone exposure	Cumulative prednisone dose and/or mean prednisone dose	12 months
