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   43841   clinical trials with a EudraCT protocol, of which   7281   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.

    General information about the trial
    Main objective of the trial
    To demonstrate the non-inferiority of Varilrix HSA-free vaccine as compared to Varilrix vaccine in terms of geometric mean titer (GMT) of varicella zoster virus (VZV) antibodies 43-57 days after the first dose vaccination. Criterion for non-inferiority: The lower limit of the 95% confidence interval (CI) for the GMT ratio (derived from immunofluorescence assay [IFA]) between Group Varilrix HSA free and (divided by) Group Varilrix is equal to or above the pre-defined clinical limit of 0.5. If this first criterion was met, an additional criterion was to be tested. Additional criterion of non-inferiority: The lower limit of the 95% CI for the GMC ratio (derived from ELISA) between Group Varilrix HSA-free and (divided by) Group Varilrix is equal to or above the pre-defined clinical limit of 0.67
    Protection of trial subjects
    The subjects were observed closely for at least 30 minutes following the administration of vaccines, with appropriate medical treatment readily available in case of a rare anaphylactic reaction.

    Notes
    [1] - The number of subjects exposed to this adverse event is less than the total number of subjects exposed for the reporting group. These numbers are expected to be equal.
    Justification: For the analysis of solicited symptoms, missing or non-evaluable measurements were not replaced. Therefore the analysis of the solicited symptoms based on the Total Vaccinated cohort included only subjects/doses with documented safety data (i.e. symptom screen/sheet completed).
