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   43874   clinical trials with a EudraCT protocol, of which   7293   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
    Can a course of antibiotics reduce the number of people with COVID-19 symptoms who go to hospital but who doctors decide do not need to be admitted from getting worse?
    (There is where worse is considered being admitted to hospital or dying).

    Another more scientific way of describing this is:
    Does giving patients who have a clinical diagnosis of COVID-19 who go to hospital with their symptoms, but who doctors decide to not need to be admitted and and are sent home, does giving these patients 14 days of an antibiotic called Azithromycin result in reducing the number of patients who then either die or get admitted to hospital with respiratory failure requiring help with their breathing either by Non-Invasive Mechanical Ventilation (NIV) or Invasive Mechanical Ventilation (IMV) in the period of 28 days from randomisation.
    E.2.2Secondary objectives of the trial
    -Are there differences in those that die in each group in the trial
    -Are there differences in those that die or are admitted to hospital for help with their breathing (when those that take part are split into those that a test called a PCR confirms that the patient does indeed have COVID-19 or not
    - Are there differences in those that progress to having pneumonia in each group
    - Are there differences in those that progress to have severe pneumonia in each group
    - Are there differences in the peak severity of illness scores in each group
    - Are these differences in the number of severe adverse events in each group
