Study summary

Uveitis and its complications are thought to account for 10 to 15% of preventable blindness in Western countries. The diagnosis of chronic non-infectious uveitis (CNUI) can be made after exclusion of pseudo uveitis or infectious uveitis, in the case of any persistent uveitis or uveitis with frequent relapses occurring less than 3 months after cessation of treatment. Adalimumab (ADA), an anti-TNFα monoclonal antibody, has marketing authorization and is widely used in the treatment of UCNI as a relay to corticosteroids. The use of ADA has been optimized, in particular through Therapeutic Drug Monitoring (TDM), based on the determination of serum ADA levels and anti-ADA antibodies. Recently, an article showed that a strategy of spacing ADA administrations in RA patients with concentrations >8 μg/mL was not inferior to standard.

Read the detailed description

There is currently no formal recommendation for spacing ADA administration in patients with chronic noninfectious uveitis, but promising data from a recent retrospective study conducted by the Croix-Rousse team, led to the proposal of a decision support algorithm. Following the example of what has been shown in rheumatoid arthritis, the investigators propose to compare a strategy of spacing ADA administrations in patients with a satisfactory clinical response associated with high serum ADA concentrations.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Informed and having signed the study consent form
  • Age ≥ 18 years
  • NICU according to the Standardization of Uveitis Nomenclature (SUN) criteria
  • Complete ophthalmological response for ≥ 48 weeks (96 weeks for uveitis related to Behçet's disease), all treatments combined
  • On ADA 40mg / 14 days for ≥ 24 weeks (i.e. achievement of the steady state for ADA concentrations)
  • Not having received systemic therapy for ≥ 12 weeks

Exclusion criteria

Exclusion Criteria:

  • Inability or refusal to understand and/or sign the form to participate in the study.
  • Inability and/or refusal to carry out the follow-up examinations required for the study.
  • Modification of any background immunomodulatory treatment (e.g. methotrexate, hydroxychloroquine, mycophenolate, etc.) associated with ADA, during the 12 weeks prior to inclusion.
  • Uveitis suspected or proven to be of infectious origin
  • Planned surgery (or other foreseeable medical event) requiring discontinuation of ADA for the duration of the study.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Active comparator
    Control arm : conventional strategy

    At W0, ADA administration will be continued every 14 days. At W24, the control arm will continue to receive ADA every 14 days regardless of serum ADA concentration.

    Diagnostic Test: Blood sample · Drug: Adalimumab Injection

  • Experimental
    Arm 2: Interventional arm : adalimumab dose spacing strategy

    At W0, if the serum ADA concentration is ≥ 8 μg/mL, ADA administration will be spaced every 21 days. At W24, if the ADA concentration is \< 3.3 μg/mL (having a serum ADA concentration above this threshold was associated with a complete therapeutic response according to one study), administrations will be repeated every 14 days. If the ADA concentration is ≥ 3.3 and \< 8μg/mL, administrations will be left every 21 days. If ADA concentration is still ≥8μg/mL, ADA administrations will be spaced every 28 days.

    Diagnostic Test: Blood sample · Drug: Adalimumab Injection

Interventions

  • Diagnostic testBlood sample

    A blood sample will be taken, in addition to blood samples taken for the usual follow-up, with 4 dry tubes for the determination of ADA and anti-ADA antibodies and for bio-collection.

What researchers measure

Primary outcomes

  1. Maintenance of a complete ophthalmological response at 48 weeks

    Number of patient with complete ophthalmological response. Ophtalmological response is defined as number of patient with, in both eyes, absence of inflammatory lesions (0 = absence) AND a cellular grade of the anterior chamber and vitreous ≤ 0.5+.

    Time frame: Week 48

  2. Infection

    Number of infection during follow-up for up to 48 weeks. Any suspected infectious event will have to be validated by a healthcare professional based on the presence of suggestive clinical signs (purulent sputum, fever ≥38°C, inflammatory syndrome, positive microbiological examination, etc.) via dedicated forms and validated by an adjudication committee.

    Time frame: Week 48

Secondary outcomes
