Criteria

Inclusion Criteria:

1. At least 18 years of age

2. Diagnosis of non-infectious intermediate, posterior, panuveitis, or chronic steroid dependent anterior uveitis

3. Failure of at least one classic synthetic DMARD including Methotrexate, Mycophenolate, Cyclosporin, Azathioprine, Cyclophosphamide, and/or at least one anti-TNF agent including Adalimumab, Infliximab, Etanercept, Golimumab or Certolizumab

4. Active disease at screening visit

5. At least 1 of the following parameters in at least one eye:

• active inflammatory chorioretinal and/or inflammatory retinal vascular lesions

• ≥ 1+ vitreous haze (Nussenblatt criteria)

• ≥ 2+ anterior chamber cells (National Eye Institute/Standardization of Uveitis Nomenclature criteria)

• Cystoid macular edema, seen on optical coherence tomography and/or fluorescein angiography

• FA leakage pattern deemed by investigators to be suggestive of active intermediate, posterior, and panuveitis, including optic disc, retinal vascular, and macular leakages

• Active snowbanking

Exclusion Criteria:

• The presence of only acute anterior uveitis.

• Serpiginous choroidopathy

• Subject with prior inadequate response to high-dose oral corticosteroids (> 60 mg of prednisone)

• Subject with confirmed or suspected infectious uveitis

• Patients with intraocular pressure of ≥ 25 mmHg or evidence of optic nerve injury

• Corneal or lens opacity that precludes adequate ophthalmic evaluation.

• Patients likely to undergo cataract surgery during the duration of the trial.

• Patients with Best Corrected Visual Acuity (BCVA) less than 20 letters (Early Treatment Diabetic Retinopathy Study)

• Dose of concomitant immunosuppressive therapy at the baseline visit:

• Methotrexate (MTX) ˃ 25 mg per week

• Cyclosporine ˃ 4 mg/kg per day

• Mycophenolate mofetil ˃ 3 grams per day or an equivalent drug to mycophenolate mofetil (e.g. mycophenolic acid) at an equivalent dose approved by the medical monitor.

• Azathioprine ˃ 175 mg per day

• Tacrolimus (oral formulation) > 8 mg per day

• If entering the study on 1 concomitant immunosuppressive therapy, dose has been increased within the last 28 days prior to Baseline visit.

• Subject has received Retisert® (implant) within 3 years prior to the Baseline visit or that has had complications related to the device. Subject has had Retisert® (implant) removed within 90 days prior to the Baseline visit or has had complications related to the removal of the device

• Subject has received intraocular or periocular corticosteroids within 30 days prior to Baseline visit

• Subject with proliferative or severe non-proliferative diabetic retinopathy or clinically significant macular edema due to diabetic retinopathy

• Subject with neovascular/wet age-related macular degeneration

• Subject with abnormality of vitreo-retinal interface (i.e., vitreomacular traction, epiretinal membranes, etc.) with the potential for macular structural damage independent of the inflammatory process, deemed macular pathology is deemed by a retinal specialist to be a potential cofounder of patient's visual acuity reduction

• Subject with severe vitreous haze that precludes visualization of the fundus at the baseline visit

• Subject has received Ozurdex® (dexamethasone implant) within 6 months prior to the baseline visit

• 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)

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

• Subject on systemic carbonic anhydrase inhibitor within 1 week prior to Screening visit

• Subject with macular edema as the only sign of uveitis

• Subject with a history of scleritis

• Subject with intolerance to high-dose oral corticosteroids (equivalent of oral prednisone 1 mg/kg/day or 60 to 80 mg/day)

• Subject on cyclophosphamide within 30 days prior to the Baseline visit

• Participation in other investigational drug or device clinical trials within 30 days prior to Day 0 or planning to participate in other investigational drug or device clinical trials within 180 days following 48 weeks after day 0. This includes both ocular and non-ocular clinical trials

• Major surgery within 8 weeks prior to screening or planned major surgery within 6 months following randomization

• Treatment with intravenous gamma globulin or plasmapheresis during the course of the trial

• Known active current or history of recurrent bacterial, viral, fungal, mycobacterial or other infections (including but not limited to tuberculosis and atypical mycobacterial disease, Hepatitis B and C, and herpes zoster, but excluding fungal infections of nail beds)

• Any major episode of infection requiring hospitalization or treatment with IV antibiotics within 4 weeks of screening or oral antibiotics within 2 weeks prior to screening

• Active tuberculosis (TB) requiring treatment within the previous 3 years. Patients should be screened for latent TB and, if positive, treated following local practice guidelines prior to initiating trial. Patients treated for tuberculosis with no recurrence in 3 years are permitted

• Primary or secondary immunodeficiency (history of or currently active)
