Randomized Trial Comparing Efficacy of Adalimumab, Anakinra and Tocilizumab in Non-infectious Refractory Uveitis

Multicentre, Randomized, Multi-arm Trial Comparing the Efficacy and Safety of Adalimumab, Anakinra and Tocilizumab in Subjects With Non-infectious Refractory Uveitis RUBI: Refractory Uveitis BIotherapies

RUBI, is the first prospective randomized, head to head study, comparing Adalimumab to either anakinra, or tocilizumab in refractory Non Infectious Uveitis (NIU). There is no firm evidence or randomized controlled trials directly addressing the best biologic agent in severe and refractory NIU. NIU can cause devastating visual loss and up to 20% of legal blindness. Corticosteroids and immunosuppressants failed to demonstrate sustainable remission over 70 % of refractory/relapsing severe uveitis. The incidence of blindness in NIU has been dramatically reduced in the recent years with the use of biologics, raising the question of whether these compounds should be used earlier in the treatment of severe non infectious uveitis. Contrasting with immunosuppressors, biotherapies act rapidly and are highly effective in steroid's sparing thus preventing occurrence of cataract and/or glaucoma.

Despite a strong rationale, these compounds are not yet approved in uveitis, which guarantees the innovative nature of this study that aims selecting or dropping any arm when evidence of efficacy already exists.

Inclusion Criteria:

1. Provide written, informed consent prior to the performance of any study specific procedures

2. 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 confirmed by documented medical history

3. Currently uncontrolled uveitic disease. Uncontrolled uveitic disease is defined as fulfilling one of the two following criteria at Inclusion:

   • Active inflammatory chorioretinal and/or inflammatory retinal vascular lesions and/or macular edema (CRT ≥300 microns) OR
   • Vitreous haze grade ≥4 on the Miami 9-step scale (or VH >1+ according to SUN/NEI classification)

4. a. Patient who are receiving prednisone ≥10 mg/day and <80mg/day (or equivalent dose of another corticosteroid) at stable dose 30 days prior to the first study drug administration on Day 0 and who received at least 1 other systemic immunosuppressant (All systemic immunosuppressants must have been discontinued 30 days prior to the first study drug administration on Day 0), or, b. Patient who received IFN alpha (All systemic immunosuppressants must have been discontinued 30 days prior to the first study drug administration on Day 0), or, c. To be intolerant to immunosuppressant

5. Best corrected visual acuity (BCVA) by ETDRS ≥ to 20/400 in either eye

6. Stable dose for two weeks prior to inclusion of topical corticosteroids and/or NSAIDs

7. Male or female , Age >= 18 years at Inclusion

8. Weight 40 - 120 kg (88.2 - 264 lbs) at Inclusion

9. Chest X-ray or thoracic CT scan results (postero-anterior and lateral) within 12 weeks prior to Inclusion with no evidence of active Tuberculosis, active infection, or malignancy

10. For female subjects of child-bearing age, a negative serum or urine pregnancy test

11. 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 roactemra 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 1:

      • 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).

12. A QuantiFERON®-Tuberculosis (TB) test within 6 months prior to Screening

Exclusion Criteria:

1. Infectious uveitis, masquerade syndromes (idiopathic uveitis is permitted)

4. Contraindication to mydriasis in either eye or presence of posterior synechiae in the study eye such that mydriasis is inadequate for posterior segment examination

5. Intraocular pressure ≥ 25 mmHg by Goldmann tonometry or advanced glaucoma in either eye
