Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   35918   clinical trials with a EudraCT protocol, of which   5893   are clinical trials conducted with subjects less than 18 years old.
    The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The study investigates whether in it is possible to reduce the dose of or even stop TNF-inhibitors without adversely affecting the control of this disease. This will be assessed by looking at:
    a. The risk of disease flares (using the disease activity score with a 28 tender and swollen joint count (DAS28). An increase of disease activity score (DAS28) of 0.6 or more represents adversely affecting disease control and is considered a flare)
    b. If flares are reversed by reverting to the original TNF inhibitor dosage
    c. If either tapering group show worse key RA assessments including disease activity (DAS28) and disability as measured by health assessment questionnaire (HAQ) scores
    d. Structural damage (plain hand and fe
    E.2.2Secondary objectives of the trial
    The secondary objectives are to investigate the effects of TNF-inhibitor tapering on:

    1. The individual components of the DAS28 scores (tender and swollen joint counts, patient global assessment of health and Erythrocyte Sedimentation rate (ESR)) and associated disease activity indices Simple disease activity score (SDAI) and clinical disease activity score (CDAI)
    2. Patient Quality of life (Health Assessment Questionnaire (HAQ) and EuroQol scores)
    3. Adverse events
    4. Radiographic progression (Plain x-rays of the hands and feet)
    5. Serum, immunological and gene expression profiles
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Biomarker substudy version
    Hypothesis: Identification of patients who are in true remission will be substantially enriched for those patients likely to best tolerate TNF inhibitor tapering to 50% initial dose.
    Primary objective: to validate the REMIRA study remission criteria, based on clinical, imaging and laboratory parameters, within the framework of the OPTTIRA to see if they can be used to predict those subjects most likely to tolerate TNF inhibitor tapering and/or withdrawal in the OPTTIRA study. The REMIRA study (Principal Investigators Scott and Cope; funded by NIHR) seeks to define the optimal combination of clinical, biological/immunological and imaging markers which most accurately predict those subjects who are in true remission.
    Experimental approach: to apply the REMIRA remission criteria at OPTTIRA study entry as part of the baseline assessment for the experimental groups 1 and 2, and again at 6 months for the control group, to predict those that will tolerate TNF inhibitor dose tapering.
    E.3Principal inclusion criteria
    a. RA by the criteria of the American College of Rheumatology
    b. Etanercept or adalimumab treatment for at least 6 months (a break of up to 4 consecutive weeks is permitted).
    c. Taking at least one DMARD from the list in the study protocol
    d. Stable clinical response for at least 3 months (one DAS28 score of at least 3.2; no changes in DAS28 >0.6 in the last 3 months)
    e. Patient considers he or she has achieved a suitable response to TNF inhibitors
    f. Supervising rheumatologist considers further improvements are unlikely on the patient’s current treatment regimen.
    g. At least 18 years of age
    h. Willing and able to give informed consent
    E.4Principal exclusion criteria
    a. Serious concurrent illness (e.g. terminal cancer)
    b. Prednisolone at more than 10mg daily (for doses > 10mg daily, a 4 week washout period is required)
    c. Recently received IM/IA steroids (4 weeks washout required)
    d. Participation in another clinical trial (other than observational or lifestyle studies and registries) concurrently or within 12 weeks of screening
    e. Pregnancy, breast-feeding or women of child-bearing potential not using adequate contraception

    E.5 End points
    E.5.1Primary end point(s)
    The primary outcome measure will be the development of flares, defined as an increase in DAS28 scores ≥ 0.6

    To ensure such changes in DAS28 represent a genuine flare in RA and are not due to unrelated events, we will take additional criteria:

    1. It must include an increase in the swollen joint count
    2. It must be present on two occasions at least one week apart
    3. It results in DAS28 scores >3.2

    Large increases in DAS28 scores (≥1.2) which result in DAS28>3.2 will not require any additional criteria.
