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   43839   clinical trials with a EudraCT protocol, of which   7280   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.

    • Mortality rate up to 30 days of life
    • Clinically significant changes in the following up to discharge from the neonatal intensive care unit (NICU):
    o Laboratory parameters
    o Cardiorespiratory monitoring
    o Vital signs
    E.5.1.1Timepoint(s) of evaluation of this end point
    Physical and Neurological Exam: Visits 1, 2, 3, 4, 5 and 7.
    Vital Signs: Hourly from birth to 24 hours postnatal and every 4 hours until 120 hours postnatal
    Respiratory Support: Every 8 hours from birth until 120 hours postnatal.
    Safety Laboratory Sampling: Prior to IMP administration, at 36 hours (± 12 hours) of life and 72 hours (± 12 hours) of life.
    Clinical Laboratory Sampling: Per routine care throughout hospitalization.
    E.5.2Secondary end point(s)
    The plasma PK of CBD will be investigated. Plasma PK parameters will be determined using a population-based approach with sparse sampling.
