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   44334   clinical trials with a EudraCT protocol, of which   7366   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
    Approximately 400 participants are expected to enroll in each of the following 3 biomarker sub-studies:
    1. Measurement of amyloid plaque burden in certain areas of the brain as measured by amyloid PET
    2. Measurement of neurofibrillary tangle burden in certain areas of the brain as measured by tau PET
    3. Measurement of disease- or treatment-related CSF biomarkers
    E.3Principal inclusion criteria
    Key Inclusion Criteria:
    - The participant must have confirmed amyloid beta pathology by CSF (historical CSF test results not allowed) or amyloid PET
    - The participant must have a history of subjective memory decline with gradual onset and slow progression over the 6 months before Screening, confirmed by study partner
    - The participant must have 1 informant/care partner who, in the Investigator's opinion, has frequent and sufficient contact with the participant (at least 10 hours/week in person or by phone) as to be able to provide accurate information about the participant's cognitive and functional abilities over time
    - The participant must meet all of the following clinical criteria for MCI due to Alzheimer's disease or mild Alzheimer's disease according to NIA-AA criteria [Albert 2011; McKhann 2011]:
    a. Have an MMSE score between 22 and 30 inclusive
    b. Have a CDR memory score >0.5
    c. Have a CDR-GS of 0.5 or 1.0
    d. Have a RBANS score of 85 or lower indicative of objective cognitive impairment (based upon the DMI score).
    - The participant must be in good health, apart from a clinical diagnosis of early Alzheimer's disease, as determined by the Investigator based on medical history and screening assessments
    - The participant must consent to ApoE genotyping
    - Must consent to apolipoprotein E (ApoE) genotyping. (Note: Participants are not required to be ApoE ε4 carriers)
    E.4Principal exclusion criteria
    Key Exclusion Criteria:
    - Any uncontrolled medical or neurological/neurodegenerative condition (other than Alzheimer's disease) that, in the opinion of the Investigator, might be a contributing cause of the participant's cognitive impairment
    - Clinically significant and/or unstable psychiatric illness within 6 months prior to Screening
    - Transient ischemic attack or stroke or any unexplained loss of consciousness within 1 year prior to Screening
    - History of severe allergic or anaphylactic reactions or of hypersensitivity to any of the inactive ingredients in the drug product
    - Participation in any study with purported disease-modifying effect in Alzheimer's disease within 12 months prior to Screening unless documentation of receipt of placebo is available
    - Current use or previous use of medications with a purported disease modifying effect in Alzheimer's disease, outside of investigational studies
    - Use of any medications that, in the opinion of the Investigator, may contribute to cognitive impairment, put the participant at higher risk for AEs, or impair the participant's ability to perform cognitive testing or complete study procedures
    - Use of any investigational drug
    - Prior exposure to aducanumab either commercially or by participation in a previous study with aducanumab. (Participants are eligible if they did not receive active aducanumab.)
    - A negative PET scan result with any amyloid-targeting ligand within 12 months prior to Screening
    NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
