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   43874   clinical trials with a EudraCT protocol, of which   7293   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.

Samples for DNA analysis will be collected at screening (or if not possible, at the next possible visit). Samples for RNA analysis will be collected at baseline, Month 6 and 12.

    Other Ancillary Studies:
    ? Microglial activation state will be investigated at selected sites and patients (N=aiming at 20 per treatment arm). Positron emission tomography (PET) scans and imaging analysis of microglial activation marker translocator protein (TSPO) will be performed at baseline and Month 12

    ? Monocyte gene expression and/or protein profile in response to treatment with laquinimod will be analyzed at selected sites and patients (N=aiming at 20 per treatment arm). Monocytes will be separated from isolated peripheral blood mononuclear cells (PBMC) and be analyzed for gene expression and/or protein profile at baseline and Month 12
    ? Peripheral cytokine and proteomic analysis in response to treatment with laquinimod will be investigated in a subgroup of patients at selected sites at baseline and Months 6 and 12.

    Ancillary Study Objectives (substudies):
    ? To explore potential correlation between genetic polymorphisms in deoxyribonucleic acid (DNA) and pharmacokinetics, clinical response to laquinimod, and/or adverse drug reactions, if these occur
    ? To explore potential correlation between ribonucleic acid (RNA) expression profile in blood cells and clinical response to laquinimod
    ? To explore changes in blood cell gene expression profile following treatment with laquinimod as potential biomarkers for laquinimod mechanism of action
    ? To evaluate changes in cytokines and other soluble protein levels following treatment with laquinimod as potential biomarkers for laquinimod mechanism of action and/or response predictive factors
    ? To explore gene expression and/or protein profile in monocytes in response to laquinimod treatment
    ? To explore change in microglial activation state in response to treatment with laquinimod
    ? To explore the potential effect on metabolic changes in the putamen and frontal white matter that are associated with the earliest stages of Huntington?s Disease
    Subestudio farmacogenómico:
    Las evaluaciones farmacogenómicas (FG) incluirán las variaciones en el ADN y los patrones de expresión génica y de ARN posiblemente relacionados con las respuestas al tratamiento clínico con laquinimod (por ejemplo, efecto clínico, evaluaciones cuantitativas motoras, farmacocinética, tolerabilidad y características de seguridad o susceptibilidad de la enfermedad y características de intensidad).

Por otra parte, en el momento basal y en el mes 12 se realizarán tomografías por emisión de positrones (PET) y análisis de imagen de la proteína translocadora marcadora de la activación microglial (TSPO).
    - En centros seleccionados se investigarán las variaciones en relación con marcadores en el putamen y la sustancia blanca frontal de la integridad neuronal (N-acetil-aspartato [NAA]) y la astrocitosis (mioinositol). Dichas investigaciones se llevarán a cabo mediante una espectroscopia de resonancia magnética nuclear (ERMN) en el momento basal y en el mes 12, y el objetivo es que 20 pacientes de cada grupo de tratamiento se sometan a esta prueba.
    - En centros y pacientes seleccionados (el objetivo es que N sea = 20 pacientes por grupo de tratamiento) se analizará la expresión génica y el perfil proteico en monocitos en respuesta al tratamiento con laquinimod. Los monocitos se separarán de las células mononucleares aisladas a partir de sangre periférica (CMSP) y se analizarán para determinar la expresión génica y/o el perfil proteico, en el momento basal y en el mes 12.
    - En un subgrupo de pacientes de centros seleccionados se evaluarán las citocinas periféricas y se llevarán a cabo análisis proteómicos, en relación con la respuesta al tratamiento con laquinimod, tanto en el momento basal como en los meses 6 y 12.
