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   43861   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.4Principal exclusion criteria
    A subject meeting any of the exclusion criteria listed below must be excluded from participating in the trial:
    The subject has a Rosen modified Hachinski Ischemia Score > 4 at Screening (ie, evidence of vascular dementia).

    The subject has a known history of stroke or evidence from screening MRI scan that is clinically important in the investigator's opinion.

    The subject has evidence of a clinically relevant neurological disorder other than the disease being studied (ie, probable AD) at Screening, including but not limited to: vascular dementia, parkinsonism, frontotemporal dementia, Huntington's disease, amyotrophic lateral sclerosis, multiple sclerosis, progressive supranuclear palsy, neurosyphilis, dementia with Lewy bodies, other types of dementia, mental retardation, hypoxic cerebral damage, cognitive impairment due to other disorders, or head trauma with loss of consciousness that led to persistent cognitive deficits.

    The subject has evidence of a clinically relevant or unstable psychiatric disorder, based on DSM IV TR criteria, including schizophrenia or other psychotic disorder, bipolar disorder, major depression, or delirium. Major depression in remission is not exclusionary.

    The subject has evidence of a current episode of major depression based on investigator's judgment. A score on the 15-item Geriatric Depression Scale of 5 or more requires an assessment by an appropriate health care professional to evaluate for the presence of major depression. Subjects with a score of 5 or more who are not diagnosed with major depression following such an assessment may be included in the trial.

    The subject?s MRI scan obtained at Screening shows evidence of a neurological disorder other than probable AD or > 4 cerebral microhemorrhages (regardless of their anatomical location or diagnostic characterization as "possible" or "definite"), a single area of superficial siderosis, evidence of a prior macrohemorrhage, > 3 lacunar infarcts, any cortical infarct over 5 mm, or any other clinically significant finding (eg, brain tumor).

    The subject has exudative (wet) age-related macular degeneration, active proliferative diabetic retinopathy, myopia or hyperopia > 8 diopters, clinically significant macula edema with diabetic retinopathy or advanced cataract to the degree that does not allow spectral-domain optical coherence tomography (SD-OCT) measurement, or other significant retinal diseases causing such significant distortion that baseline measurements would be too greatly abnormal to allow reasonable detection of possible change.

    The subject has a history of hepatitis or liver disease that, in the opinion of the investigator, has been active within the 6 months prior to Screening.

    The subject has a recent or ongoing, uncontrolled, clinically significant medical condition within 3 months of the Screening Visit (such as, but not limited to, diabetes, hypertension, thyroid or endocrine disease, congestive heart failure, angina, cardiac or gastrointestinal disease, dialysis, or abnormal renal function with estimated creatinine clearance < 50 mL/min) other than the condition being studied such that, in the judgment of the investigator, participation in the trial would pose a significant medical risk to the subject. Controlled co-morbid conditions (including diabetes, hypertension, heart disease, etc) are not exclusionary, if stable within 3 months of the Screening Visit. All concomitant medications, supplements, or other substances must be kept as stable as medically possible during the trial.

    The subject has a history or current evidence of long QT syndrome, QTC interval ? 470 milliseconds (for male subjects) or ? 480 milliseconds (for female subjects), or torsades de pointes.

    The subject has a history of malignancy occurring within the 5 years immediately before Screening, except for a subject who has been adequately treated for
    1. basal cell or squamous cell skin cancer,
    2. in situ cervical cancer, or
    3. localized prostate carcinoma; or
    4. who has undergone potentially curative therapy with no evidence of recurrence for ? 3 years post therapy, and who is deemed at low risk for recurrence by her/his treating physician.

    The subject has
    1. a history of clinically significant vitamin B12 or folate deficiency in the 6 months immediately before Screening, or
    2. vitamin B12 or folate deficiency in addition to increased serum homocysteine or methylmelonic acid levels at Screening as determined by central laboratory normal values.
    El sujeto presenta una puntuación de isquemia de Hachinski modificada por Rosen > 4 en el momento de selección (es decir, signos de demencia vascular).
    El sujeto tiene antecedentes de ictus o signos en la RM de selección que, en opinión del investigador, son clínicamente importantes.
    El sujeto tiene signos de un trastorno neurológico clínicamente importante diferente de la enfermedad en estudio (es decir, EA probable) en el momento de selección, entre los que figuran: demencia vascular, parkinsonismo, demencia frontotemporal, enfermedad de Huntington, esclerosis lateral amiotrófica, esclerosis múltiple, parálisis supranuclear progresiva, neurosífilis, demencia con cuerpos de Lewy, otros tipos de demencia, retraso mental, lesión cerebral hipóxica, deterioro cognitivo debido a otros trastornos o traumatismo craneoencefálico con pérdida de conocimiento que produjo déficit cognitivos persistentes.
    El sujeto tiene signos de un trastorno psiquiátrico inestable o clínicamente importante, según los criterios del DSM-IV-TR, como esquizofrenia u otro trastorno psicótico, trastorno bipolar, depresión mayor o delirium. La depresión mayor en remisión no será motivo de exclusión.
    El sujeto tiene signos de un episodio presente de depresión mayor, a juicio del investigador. Una puntuación en la Escala de depresión geriátrica de 15 apartados de 5 o más exigirá una evaluación por un profesional sanitario apropiado para evaluar la presencia de una depresión grave. Los sujetos con una puntuación de 5 o superior que no sean diagnosticados de depresión mayor después de dicha evaluación podrán participar en el ensayo.
    La RM del sujeto obtenida durante la selección muestra indicios de un trastorno neurológico distinto de una EA probable o más de 4 microhemorragias cerebrales (con independencia de su localización anatómica o caracterización diagnóstica como ?posible? o ?confirmada?), una única zona de siderosis superficial, datos de una macrohemorragia previa, más de 3 infartos lagunares, un infarto cortical mayor de 5 mm o cualquier otro hallazgo clínicamente importante (por ejemplo, tumor cerebral).
    El sujeto tiene degeneración macular exudativa (húmeda) relacionada con la edad, retinopatía diabética proliferativa activa, miopía o hipermetropía > 8 dioptrías, edema macular clínicamente significativo con retinopatía diabética o una catarata avanzada en un grado que impida la medición mediante tomografía óptica de coherencia de dominio espectral (SD-OCT), u otras enfermedades significativas de la retina que causen una alteración tan significativa que las determinaciones basales sean demasiado anormales para permitir la detección razonable de un posible cambio.
    El sujeto tiene antecedentes de hepatitis o hepatopatía que, en opinión del investigador, ha estado activa en los 6 meses anteriores a la selección.
    El sujeto tiene una afección médica de importancia clínica, no controlada, reciente o activa en los 3 meses anteriores a la visita de selección (como, por ejemplo, diabetes, hipertensión, enfermedad tiroidea o endocrina, insuficiencia cardíaca congestiva, angina de pecho, cardiopatía, enfermedad digestiva, diálisis o disfunción renal con un aclaramiento de creatinina calculado < 50 ml/min) diferente de la enfermedad en estudio, de manera que, en opinión del investigador, su participación en el estudio le supondría un riesgo médico importante. Las enfermedades coexistentes controladas (como diabetes, hipertensión, cardiopatía, etc.) no serán motivo de exclusión siempre que se hayan mantenido estables en los tres meses anteriores a la visita de selección. Todos los medicamentos concomitantes, suplementos u otras sustancias tendrán que mantenerse tan estables como sea médicamente posible durante el ensayo.
    El sujeto tiene antecedentes o indicios presentes de síndrome del QT largo, intervalo QTc ? 470 ms (en varones) o ? 480 ms (en mujeres) o torsades de pointes.
