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 Objective of the trial
    E.2.1Main objective of the trial
    To determine whether the addition of the molecule Cannabidiol (CBD) leads to improvement in the severity of core psychotic symptom, in patients experiencing their first psychotic episode who have failed to recover despite treatment with at least one standard anti-psychotic drug.
    E.2.2Secondary objectives of the trial
    To determine whether the addition of CBD to an existing antipsychotic treatment regime offers 'protection' against the metabolic consequences associated with standard anti-psychotic treatment, namely weight-gain, hyperglycaemia and dyslipidaemia.

    To determine whether measures of brain activity using magnetic resonance imaging can predict response to CBD, and whether these measures change with response to CBD.
