"Comparison of the Efficacy and Safety of Adalimumab to That of Tocilizumab in Severe Uveitis of Behçet's Disease" (UVB)

"Multicenter, Randomized, Prospective Trial Comparing the Efficacy and Safety of Adalimumab to That of Tocilizumab in Severe Uveitis of Behçet's Disease" (UVB) : Treatment of UVeitis in Behçet's Diseases With Biologics

UVB, is the first randomized prospective, head to head study, comparing Adalimumab to Tocilizumab in sight threatening uveitis of Behçet's Disease (BD). Anti-TNFα has been used for BD uveitis for 15 years. The incidence of blindness in BD has been dramatically reduced in the recent years with the use of biologics. There is no firm evidence or randomized controlled trials directly addressing the best induction therapy in severe BD uveitis. BD uveitis is considered as the most devastating inflammatory ocular disease. Risk of visual loss reaches 25% at 5 years and 80% of patients have a bilateral involvement. Contrasting with immunosuppressors or interferon-alpha, biotherapies act rapidly and are highly effective in steroid's sparing thus preventing occurrence of cataract and/or glaucoma. However, anti-TNFα failed to demonstrate sustainable complete remission over 50 % of severe sight threatening uveitis. There is little published information on use of biologics other than anti-TNFα for severe BD uveitis. Tocilizumab has been used with success in severe and/or resistant cases and is one of the most promising biologics in BD. IL-6 expression correlates with BD activity and other immunological data provide a strong rationale for targeting BD with tocilizumab. Despite a strong rationale, these compounds are not yet approved in BD, which guarantees the innovative nature of this study that aims selecting or dropping any arm when evidence of efficacy already exists. The objective of the study is to assess the benefit of tocilizumab comparatively to that of adalimumab in sight-threatening Behçet's disease uveitis at week 16

4. Diagnosis of non-infectious intermediate, posterior-, or pan-uveitis in at least one eye fulfilling the International Study Group Classification Criteria (Standardization of Uveitis Nomenclature [SUN] criteria) of posterior, or pan- uveitis
5. Sight threatening uveitis defined according to the validated international definition as 2 lines of drop in visual acuity on a 10/10 scale, and/or retinal inflammation (macular oedema and/or retinal vasculitis).
6. Chest X-ray (postero-anterior and lateral) or CT-scanner results within 12 weeks prior to Inclusion with no evidence of active Tuberculosis, active infection, or malignancy

8. For subjects with reproductive potential, a willingness to use contraceptive measures adequate to prevent the subject or the subject's partner from becoming pregnant during the study and 3 and 5 months after stopping therapy for tocilizumab and adalimumab, respectively. Birth control methods which may be considered as highly effective methods that can achieve a failure rate of less than 1% per year when used consistently and correctly are considered as highly effective birth control methods (according to CTFG recommendations). Such methods include:

   • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation:

     • oral
     • intravaginal
     • transdermal

     • oral
     • injectable
     • implantable
   • intrauterine device (IUD)
   • intrauterine hormone-releasing system (IUS)
   • bilateral tubal occlusion
   • vasectomised partner
   • sexual abstinence (In the context of this guidance sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject).

   For male subjects :

   • use of a condom
   • vasectomy (with documentation of azoospermia)
   • sexual abstinence
9. A potential subject with a positive interferon-gamma release assay (IGRA) (e.g., QuantiFERON®-TB Gold or T-spot TB® Test) obtained within 6 months prior to inclusion is eligible if her/his chest X-ray does not show evidence suggestive of active TB disease and there are no clinical signs and symptoms of pulmonary and/or extra-pulmonary TB disease. These subjects with a latent TB infection who have not already received a prophylactic TB treatment must agree in advance to complete such a treatment course. The treatment should be started at the latest at inclusion.

Exclusion Criteria:
