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 Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Pharmacometric Substudy - Secondary analysis of pharmacodynamic (PD) endpoints for efficacy and corticosteroid toxicity (in the corticosteroid group) will be performed using a new, preliminary validated tool called the paediatric glucocorticoid toxicity index (pGTI). Drug dose will be taken as the input with an estimated parameter for the decay in drug effect being used as a proxy for PK (K-PD approach). The efficacy analysis will consider linear and nonlinear mixed effects models of coronary Z-score over time with multivariable covariate analysis. The model will aim to identify possible differences between groups, and dose response (IVIG and corticosteroid cumulative dosing) corrected for important covariates such as CRP, age etc. The pGTI evolution in time with also be modelled using either linear or nonlinear mixed effects. The composite pGTI score will be treated as both a continuous variable and we will also consider sub-score modelling to assess which items are most susceptible to change in short-course therapy, which may lead to refinement of the score itself. Diagnostic Biomarker Substudy - The collection of throat swab and low volume blood samples at multiple timepoints will be invaluable for future research on the diagnosis, aetiology, pathogenesis and genetics of the disease.
    Subestudio farmacométrico: se realizará un análisis secundario de los criterios de valoración farmacodinámicos (PD) para determinar la eficacia y la toxicidad de los corticosteroides (en el grupo de corticosteroides) mediante una innovadora herramienta validada preliminarmente llamada índice de toxicidad por glucocorticoides pediátricos (pGTI). La dosis del fármaco se tomará como entrada con un parámetro estimado asignado para la disminución del efecto del fármaco que se utilizará como un sustituto de la PK (enfoque K-PD). El análisis de eficacia considerará modelos de efectos mixtos lineales y no lineales de puntuación Z coronaria a lo largo del tiempo con análisis de covariables multivariables. El modelo tendrá como objetivo identificar las posibles diferencias entre los grupos y la respuesta a la dosis (IgIV y dosificación acumulada de corticosteroides) corregida para covariables importantes como Proteína C reactiva, edad, etc. La evolución de pGTI en el tiempo también se modelará utilizando efectos mixtos lineales o no lineales. La puntuación pGTI compuesta se tratará como una variable continua y también consideraremos el modelado de subpuntuaciones para evaluar qué elementos son más susceptibles a cambios en la terapia de corta duración, lo que puede conducir a un refinamiento de la puntuación en sí. Subestudio de biomarcadores de diagnóstico: se llevará a cabo la recolección de muestras de sangre y frotis de garganta en diferentes momentos del estudio con el objetivo de realizar investigaciones futuras sobre el diagnóstico, etiología, patogénesis y genética de la enfermedad.

OR abnormal echocardiogram compatible with KD but without established CAA, with ≥ 3 of the following suggestive features: decreased left ventricular function, mitral regurgitation, pericardial effusion, or dilated but non-aneurysmal coronary arteries (internal diameter 2≤Z<2.5; and not meeting the exclusion criteria for aneurysmal change as defined below). 3. Written informed consent from appropriate legal representative(s), and assent from patients who have not reached the age of consent and will not reach the age of consent for the duration of the trial in the participating country, but are judged to have capacity for this (depending on both age and acuity of illness) *This definition of incomplete KD is modified from the AHA definition by firstly, the exclusion of aneurysmal coronary artery changes as the sole echo finding, since this is an exclusion criterion for KD-CAAP, and secondly the inclusion of low platelet count as well as high platelet count, as highlighted in recent European consensus SHARE guideline. Note that patients with KD can still be included in KD-CAAP if they have started IVIG treatment, as long as they are randomised no more than 24 hours after the IVIG infusion is initiated (see exclusion criteria). Test results must be from tests done on the calendar day of randomisation or the day before.

    E.5 End points
    E.5.1Primary end point(s)
    KD-CAAP will have two co-primary outcome measures: Any CAA (definition below) documented within the 12 weeks of trial follow-up (to assess overall effectiveness of the strategy of immediate corticosteroids in preventing CAA, expecting that some patients will receive rescue treatment before reaching this endpoint in both randomised groups). An average estimate across weeks 1, 2, and 6 of the maximum of the Z-score of the internal diameters of the proximal right coronary artery or left anterior descending coronary artery, adjusting for rescue treatment (to assess the direct efficacy of corticosteroids).

Cada centro se cerrará una vez que se complete la limpieza de datos en ese centro; se informará a las autoridades reguladoras pertinentes y al comité de ética.

An answer of yes could have included women of child bearing potential whether or not they would be using contraception. The answer should therefore be understood in that context.

    F.5 Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)
    There are no arrangements for continued provision of the intervention for participants once the research has ended. This is because it is expected that by the week 12 visits all patients will have completed their corticosteroids. Participants taper their corticosteroids over 15 days upon resolution of their fever and their CRP is equal to or below 10mg/L. Follow-up thereafter is soley dependent on the routine follow up that would be offered as standard of clinical care.
    No se preve administración continuada del tratamiento de intervención una vez haya finalizado la participación de los pacientes en el ensayo. Se espera que en la semana 12 todos los pacientes hayan finalizado su tratamiento con corticosteroides. La dosis de corticosteroides se reduce gradualmente durante 15 días después de la resolución de la fiebre y cuando el valor de PCR alcanza valor igual o inferior 10 mg/L. El seguimiento posterior se realizará como parte de la práctica clínica habitual.
