Efficacy and Tolerance of Baricitinib, a JAK Inhibitor, in the Treatment of Refractory Non-infectious Non-anterior Uveitis

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to evaluate the efficacy of Baricitinib, a JAK1 and 2 inhibitor, in the management of non-infectious non-anterior uveitis refractory to at least one line of biotherapy (anti-TNF alpha, tocilizumab) after 6 months of treatment

Eligibility Criteria
-----------------
Inclusion Criteria: Patient with diagnosis of non-anterior non-infectious uveitis, refractory to at least one line of biotherapy (anti-TNF alpha, tocilizumab) Need to stop biotherapy (anti-TNF alpha or tocilizumab) and conventional immunosuppressive drugs (mycofenolate mofetil, methotrexate, azathioprine, cyclosporine, interferon alpha 2a) for at least 10 days prior to the inclusion date Exclusion Criteria: 1. Isolated anterior uveitis. 2. Infectious uveitis. 3. Severe uveitis threatening the visual prognosis and requiring emergency treatment with intravenous corticosteroids. 4. Initial visual acuity > 1.3 LogMAR in at least one eye. 5. Corneal or lens opacity that prevents fundus visualization or may require cataract surgery during the study. 6.
