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.

    Pre-screening Epoch and Genetic Disclosure Follow-up exclusion criteria:
    1. Any disability that may prevent the participants from completing all study requirements.
    2. Current medical or neurological condition that might impact cognition or performance on cognitive assessments e.g., MCI, dementia, Huntington’s disease, Parkinson’s disease, Lyme disease, schizophrenia, bipolar disorder, major depression, active seizure disorder, history of multiple traumatic brain injuries, alcohol/drug abuse or dependence currently, or dependence within the last two years.
    3. Advanced, severe progressive or unstable disease that may interfere with the safety, tolerability and study assessments, or put the participant at special risk, e.g. active hepatitis, HIV infection, severe renal impairment, severe hepatic impairment, uncontrolled or significant cardiac disease including recent myocardial infarction, congestive heart failure.
    4. History of malignancy of any organ system, treated or untreated, within the past 60 months, regardless of whether there is evidence of local recurrence or metastases. However, localized nonmalignant tumors not requiring systemic chemo- or radio-therapy, localized basal or squamous cell carcinoma of the skin, or in-situ cervical cancer are permitted.
    5. History of hypersensitivity to any of the investigational drugs or their excipients/adjuvant, or to drugs of similar chemical classes.
    6. Indication for or current treatment with ChEIs and/or another AD treatment.
    7. Contraindication or intolerance to MRI.
    Screening and Treatment Epoch exclusion criteria:
    Participants fulfilling any of the following criteria prior to randomization will be excluded.
    Participants, who fulfill one or more exclusion criteria due to a temporary condition, or the use of treatment requiring a specific time window prior to randomization, can be re-screened at a later stage:
    1. Brain MRI results from the central reading showing findings unrelated to AD that, in the opinion of the Investigator might be a leading cause of cognitive decline, might pose a risk to the participant, or might confound MRI assessment for safety monitoring.
    For Cohort I (CAD 106) only, in addition, evidence of ARIAH as demonstrated by:
    - More than four cerebral microhemorrhages regardless of their anatomical location;
    - Single area of superficial siderosis of the CNS or evidence of a prior cerebral macrohemorrhage.

Score “yes” on item four or item five of the Suicidal Ideation Section of the C-SSRS if this ideation occurred in the past six months, or “yes” on any item of the Suicidal Behavior Section, except for the “Non-Suicidal Self-Injurious Behavior” if this behavior occurred in the past two years prior to screening.
    3. A positive drug screen at Screening, if, in the Investigator’s opinion, this is due to drug abuse. Participants with a positive drug screen not believed to be related to drug abuse, can be re-screened once.
    4. Significantly abnormal laboratory results at Screening, meeting the exclusionary alert values specified in the Laboratory Manual. If, in the opinion of the Investigator, an abnormal finding is the result of a temporary condition, the laboratory test can be repeated once.
    5. Current clinically significant ECG findings.
    6. Use of other investigational drugs prior to screening until:
    - Blood concentration has returned to Baseline (or below Serological responder threshold) for biologics, e.g. antibodies induced by active immunotherapy; or

Contraindication to lumbar puncture, e.g. low platelet count, abnormal prothrombin time international normalized ratio, history of lumbar-spinal surgery, signs or symptoms of intracranial pressure, spinal deformities or other spinal conditions that in the judgment of the Investigator would preclude a lumbar puncture.
    No additional exclusions may be applied by the Investigator in order to ensure that the study population will be representative of all eligible participants.

    3. Resultado positivo en el análisis toxicológico realizado en la etapa de selección si, en opinión del investigador, se debe a drogadicción.

Si, en opinión del investigador, un hallazgo anómalo es resultado de un proceso temporal, la determinación analítica podrá repetirse una vez.
    5. Hallazgos electrocardiograficos de importancia clínica de un servicio de interpretación central 6. Uso de otros fármacos en investigación antes de la selección hasta:
    •El regreso de la concentración sanguínea a los valores basales o por debajo del umbral de la respuesta serológica en el caso de anticuerpos inducidos por inmunoterapia activa.

    7. Tratamiento en las cuatro semanas previas a la aleatorización con cualquier fármaco o terapia con potencial conocido de causar toxicidad orgánica importante, es decir, fármacos que puedan precisar la vigilancia de seguridad periódica de un órgano o liquido corporal especifico
