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   44235   clinical trials with a EudraCT protocol, of which   7336   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.

    Other protocol defined Inclusion criteria may apply. Please refer to section 8.1 Inclusion Criteria for a full list.

    LTE Treatment Period:
    - Participant must have completed the Core study period (Week 102) and adequately tolerated 10 mg/kg of aducanumab during the Core study period in the opinion of the Investigator.

    E.5 End points
    E.5.1Primary end point(s)
    Core Treatment Period:
    1. Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
    An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. A SAE is any untoward medical occurrence that at any dose results in death, life-threatening event, requires inpatient hospitalization, significant disability/incapacity or congenital anomaly.

    2. Number of Participants with AEs Leading to Treatment Discontinuation or Study Withdrawal
    An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

    3. Number of Participants with Amyloid-related Imaging Abnormality-Edema (ARIA-E)
    Magnetic resonance imaging (MRI) readings will be used to assess ARIA-E severity as mild, moderate and severe.

    4. Number of Participants with Amyloid-related Imaging Abnormality- Hemorrhage or Superficial Siderosis (ARIA-H)
    MRI readings will be used to assess severity of ARIA-H microhemorrhages and superficial siderosis.

    5. Number of Participants With Anti-aducanumab Antibodies (antidrug antibodies, ADAs) in Serum
    Presence of serum ADAs will be determined using a validated assay.
