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.

    SpO2 values of > 92% on room air that are at least 8 hours apart.
    • For any patient requiring supplemental oxygen therapy at the time of
    enrollment (regardless of oxygen saturation), time to cessation of oxygen support.
    • Evaluate the effect of VIS410 + oseltamivir vs oseltamivir alone on the
    parameters described on the protocol.

    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy outcome analysis compares Day 7 clinical status
    ordinal scale scores between treatment groups, and between all VIS410

    using the below seven-level ordinal scale, with the classifications
    presented from the worst clinical outcome to the best clinical outcome in
    descending order; for each day, subject status will be classified by the
    worst clinical outcome for which they qualify.
