Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43857   clinical trials with a EudraCT protocol, of which   7284   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).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Male or female aged 2 to <18 years.

    2. Must meet International League Against Rheumatism (ILAR) JIA classification for one of the following categories and, in the opinion of the investigator, have active disease for at least 6 weeks prior to screening:
    - Extended oligoarthritis;
    - Polyarthritis (RF+);
    - Polyarthritis (RF-);
    - Systemic JIA with active arthritis but without active systemic features in the prior 6 months and at the time of enrollment;
    - Psoriatic arthritis;
    - Enthesitis-related arthritis.

    Subjects with polyarticular course JIA (ie, extended oligoarthritis, polyarthritis RF+, polyarthritis RF-, systemic JIA with active arthritis but without active systemic features) must have a minimum of 5 active joints (an active joint is defined as a joint with swelling or, in the absence of swelling, limited range of motion accompanied by either pain on motion or tenderness) at screening and baseline to be eligible for study entry.

    Subjects with psoriatic or enthesitis-related arthritis must have a minimum of 3 active joints (an active joint is defined as a joint with swelling or, in the absence of swelling, limited range of motion accompanied by either pain on motion or tenderness) at screening and baseline to be eligible for study entry.

    Treatment with stable doses of a Non-Steroidal Anti-inflammatory Drug (NSAID) and/or a stable dose of an oral glucocorticoid, and/or a stable dose of methotrexate is permitted.

    For subjects receiving an oral glucocorticoid: Glucocorticoids may be administered at a maximum dose of 0.2 mg of prednisone equivalent per kilogram per day or 10 mg per day for 2 weeks before baseline, whichever is lower.

    For subjects receiving methotrexate (MTX) treatment: MTX may be administered either orally or parenterally at doses not to exceed 25 mg/wk or 20 mg/m2/week (whichever is lower); participants must have taken MTX for 3 months and be at a stable dose for at least 6 weeks before baseline. Subjects taking MTX must be taking folic acid or folinic acid in accordance with local standards.

    For subjects with psoriatic arthritis, the following topical treatments for psoriasis are allowed: non-medicated emollients for use over the whole body; topical steroids including hydrocortisone and hydrocortisone acetate 1% for the palms, soles, face, and intertriginous areas only; tar, salicylic acid preparations, and shampoos free of corticosteroids are permitted only for the scalp.

    3. Inadequate response or intolerance to at least one Disease Modifying Anti-Rheumatic Drug (DMARD), which may include MTX or biologic agents (see Appendix 1); in the case of ERA and psoriatic arthritis, inadequate response to Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).

    4. No evidence or history of untreated or inadequately treated active or latent tuberculosis (TB) infection as evidenced by the following:
    a. A negative QuantiFERON -TB Gold In-Tube test performed within the 3 months prior to screening. A negative purified protein derivative (PPD) test can be substituted for the QuantiFERON-TB Gold In-Tube test only if the central laboratory is unable to perform the test or cannot determine the results to be
    positive or negative and the Pfizer medical monitor is informed and agrees on a case-by-case basis.

    b. Chest radiograph without changes suggestive of active tuberculosis (TB) infection within 3 months prior to screening is recommended and should be performed according to local standards of care or country-specific guidelines.

    c. No history of either untreated or inadequately treated latent or active TB infection.

    If a subject has previously received an adequate course of therapy for either latent (9 months of isoniazid in a locale where rates of primary multi-drug resistant TB infection are <5% or an acceptable alternative regimen) or active (acceptable multi-drug regimen) TB infection, neither a PPD test nor a QuantiFERON-Gold TM test need be obtained. A chest radiograph should be obtained if not done within the 3 months prior to screening (see Section 7.2.6). To be considered eligible for the study, the chest radiograph must be negative for active tuberculosis infection.

    A subject who is currently being treated for latent TB infection can only be enrolled with confirmation of current incidence rates of multi-drug resistant TB infection, documentation of an adequate treatment regimen, and prior approval of the Sponsor.

    5. Fertile males and females who are, in the opinion of the investigator, sexually active and at risk for pregnancy with their partner(s) must be willing and able to use a highly effective method of contraception as outlined in this protocol during the study and for at least 28 days after the last dose of study medication.

    Note: Refer to Section 4.4.1 for additional contraception requirements
    for investigative sites in UK, Spain, Poland, and Belgium only.

    Se permite el tratamiento con dosis estables de un fármaco antiinflamatorio no esteroideo (AINE) y/o una dosis estable de un glucocorticoide oral y/o una dosis estable de metotrexato.

    Para sujetos que reciben un glucocorticoide oral: Los glucocorticoides se pueden administrar a una dosis máxima de 0,2 mg de equivalente a la prednisona por kilogramo al día o 10 mg al día durante ≥2 semanas antes del inicio, lo que sea menor.

    Para sujetos que reciben tratamiento con metotrexato (MTX): El MTX se puede administrar por vía oral o parenteral a dosis que no superen los 25 mg/semana o 20 mg/m2/semana (lo que sea menos); los participantes deben haber tomado MTX durante ≥3 meses y estar recibiendo una dosis estable durante al menos 6 semanas antes del inicio. Los sujetos que toman MTX deben estar tomando ácido fólico o ácido folínico de acuerdo con los estándares locales.

    a. Una prueba QuantiFERON®-TB Gold In-Tube negativa realizada dentro de los 3 meses previos a la selección. Una prueba de negativa de derivado de proteína purificada (purified protein derivative, PPD) se puede sustituir por la prueba QuantiFERON®-TB Gold In-Tube, solo si el laboratorio central no puede realizar la prueba o no puede determinar los resultados como positivos o negativos y se informa al supervisor médico de Pfizer, y está de acuerdo caso por caso.
    b. Se recomienda una radiografía de tórax sin cambios que sugieran infección por tuberculosis (TB) activa dentro de los 3 meses previos a la selección , y se debe realizar de acuerdo con las normas asistenciales locales o las directrices específicas del país.
    c. Sin antecedentes de infección por TB activa o latente no tratada o tratada de forma inadecuada.
    Si un sujeto ha recibido previamente un curso adecuado de tratamiento para infección por TB latente (9 meses de isoniazid en un lugar en el que las tasas de infección por TB resistente a múltiples fármacos primarios son del <5 % o una pauta alternativa aceptable) o activa (pauta de múltiples fármacos aceptable), no se requiere una prueba PPD ni una prueba QuantiFERON-Gold®TM. Se debe obtener una radiografía de tórax si no se ha hecho dentro de los 3 meses previos a la selección. Para que se pueda considerar a un sujeto como apto para el estudio, la radiografía de tórax debe ser negativa para la infección por tuberculosis activa.
