A Study of Mycophenolate Mofetil Combined With Glucocorticoid Therapy in Relapse Vogt-Koyanagi-Harada Disease

Tianjin Medical University15 enrolled

Overview

This project is designed to test the hypothesis that Mycophenolate Mofetil is clinically useful for patients with relapse Vogt-Koyanagi-Harada disease

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 Mycophenolate Mofetil, its potential risks and benefits. This is a monocenter, cohort, observational study evaluating patients with relapse VKH divided into two groups: Mycophenolate Mofetil therapy group and traditional therapy group. For Mycophenolate Mofetil therapy group, an initial dose of 0.5-1.0g bid MMF was orally administered every day, glucocorticoid was started at a dose of 0.5-0.8 mg/kg/day and no more than 60 mg/day. For the traditional therapy group, patients were treated with glucocorticoids alone or glucocorticoids combined with Cyclosporine. 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 MMF in treatment of relapse VKH.

Inclusion Criteria: 1. Subject is 18 to 70 years of age. 2. Subjects who do not have previous, active or latent tuberculosis (TB). 3. Subject must start Vogt-Koyanagi-Harada disease more than two months, and develop at least one recurrence. Exclusion Criteria: 1. Subject with confirmed or suspected infectious uveitis, including but not limited to infectious uveitis due to TB, cytomegalovirus (CMV), Human T-Lymphotropic Virus Type 1 (HTLV-1), Whipple's disease, Herpes Zoster virus (HZV), Lyme disease, toxoplasmosis and herpes simplex virus (HSV). 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 (except intravitreal anti-vascular endothelial growth factor \[VEGF\] 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

RECRUITING

Outcomes

Primary Outcomes

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.

Time frame: 24 weeks

Recurrence rate

The recurrence rates in Mycophenolate mofetil treatment group and control group

Time frame: 24 weeks

Secondary Outcomes

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.

Time frame: 24 weeks

Prednisone exposure

Cumulative prednisone dose and/or mean prednisone dose

Time frame: 12 months
