E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Age 18 at Inclusion 2. Provide written, informed consent prior to the performance of any study specific procedures 3. Diagnosis of Behçet’s disease according to the International Criteria for Behçet's Disease (ICBD) (see appendix 1) or history of aphtosis. 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 7. For female subjects of child-bearing potential, a negative pregnancy test (plasmatic or urinary) 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 1: oral intravaginal transdermal - progestogen-only hormonal contraception associated with inhibition of ovulation : 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). 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. 10. Affiliation to a social security system |

E.4 | Principal exclusion criteria |

History of malignancy within 5 years prior to Inclusion other than carcinoma in situ of the cervix or adequately treated, non-metastatic squamous or basal cell carcinoma of the skin. 5. History of severe allergic or anaphylactic reactions to monoclonal antibodies 6. History of multiple sclerosis and/or demyelinating disorder 7. Laboratory values assessed during Inclusion: a. Neutrophil < 1.0 103/mm3 b. Platelet count < 80 103/mm3 c. ASAT or ALAT > 5 ULN 8. Treatment with anti-TNF and/or Tocilizumab therapy within 1 month prior to inclusion 9. if on azathioprine, mycophenolate mofetil, or methotrexate at the time of inclusion, these drugs must be withdrawn prior to receiving the tocilizumab or adalimumab dose on Day 0. 10. Stage III and IV New York Heart Association (NYHA) cardiac insufficiency 11. Severe renal (Glomerular filtration rates (GFR) <30ml/min) or liver insufficiency (prothrombin <50% without other causes) 12. Any live (attenuated) vaccine within 30 days prior to inclusion; |
