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   42564   clinical trials with a EudraCT protocol, of which   7007   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    E.2.3.1Full title, date and version of each sub-study and their related objectives
    A single blood sample will be obtained from subjects who agree to participate in genotyping evaluation of Apolipoprotein E (ApoE), if a separate informed consent is signed by the subject or by a legally acceptable representative. The blood sample may be collected any time after eligibility for randomization and continued participation in the study has been confirmed. A volume of approximately 10 mL is to be collected and immediately stored under frozen conditions (placed on dry ice) prior to shipment. Samples should then be shipped frozen (on dry ice) to the central laboratory (Covance) on the day of collection where they will be stored at -70°C. Samples will be destroyed at the end of the study.
    Se obtendrá una única muestra de sangre de los sujetos que acepten participar en la evaluación del genotipado de la apolipoproteína E (ApoE), si el sujeto o un representante legalmente aceptable firman un consentimiento informado por separado. La muestra de sangre se puede tomar en cualquier momento después de la elegibilidad para la aleatorización y se ha confirmado la continuación de la participación en el estudio. Se debe recoger un volumen de aproximadamente 10 ml y almacenar inmediatamente en condiciones de congelación (colocar en hielo seco) antes del envío. Las muestras deben enviarse congeladas (en hielo seco) al laboratorio central (Covance) el día de la recolección, donde se almacenarán a -70 ° C. Las muestras serán destruidas al final del estudio
    E.3Principal inclusion criteria
    1. Early AD, encompassing probable AD and mild cognitive impairment due to AD (MCI-AD) based on 2011 National Institute on Aging (NIA)/ Alzheimer’s Association (AA) criteria
    • All cause dementia and probably AD (probably AD)
    In brief, subjects with probable AD dementia must have insidious onset, worsening impairment in at least two cognitive areas (learning and recall, language, executive function, visuospatial skills), sufficient to significantly interfere with work or usual activities, that is not explained by delirium, drugs, major psychiatric disorder, medical illness, cerebrovascular disease, other forms of dementia, or neurological disorder. The accuracy of the diagnosis will be confirmed independently.
    In subjects with MCI-AD, there should be evidence of concern about a change in cognition, in comparison with the person’s previous level verified by a knowledgeable informant or clinician. There should also be evidence of lower performance in episodic memory than would be expected for the subject’s age and educational background (typically 1 to 1.5 standard deviations below the mean). Other mild cognitive deficits may also be present, but there must be preservation of independence in functional abilities. Subjects should not meet the criteria for dementia. The cognitive changes must be mild and there must be no evidence of a significant impairment in social or occupational functioning. Impairments must not be explained by delirium, drugs, major psychiatric disorder, medical illness, cerebrovascular disease, other forms of dementia, or neurological disorder.

    Los sujetos en los que la vitamina B12 es <150 pg/ml se pueden aceptar si el investigador confirma que no afecta al estado cognitivo del sujeto y que este se complementa según proceda antes del inicio del medicamento de estudio
    13.Valor anormal analítico de bioquímica sérica en la selección considerado clínicamente relevante por el investigador, p. ej., los que se considera que tienen potencial de aumentar el riesgo asociado con la participación en el estudio o la administración del producto en investigación y que, a juicio del investigador, harían que el sujeto sea inapropiado para entrar en este estudio. Asimismo, deben excluirse sujetos con cualquiera de las siguientes anomalías:
    •Aclaramiento de creatinina <30 ml/min en la selección, estimado por el laboratorio central de acuerdo con la ecuación de Cockcroft y Gault
    •Hormona estimulante de la tiroides (TSH, por sus siglas en inglés) por encima del rango normal de laboratorio (el sujeto puede ser tratado [si está clínicamente indicado de conformidad con las pruebas de laboratorio adicionales] y reevaluado después de 90 días)
    Para criterios de exclusión 14 a 20, consulte el protocolo
