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   43865   clinical trials with a EudraCT protocol, of which   7286   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 non-inferiority of the MenACWY liquid vaccine with approximately 30% Men A Free Saccharide (FS) to that of currently licensed MenACWY vaccine, as measured by the human serum bactericidal assay (hSBA) Geometric Mean Titers (GMTs) directed against N. meningitidis serogroup A at Day 29 after a single dose vaccination. Criterion to demonstrate non-inferiority: Non-inferiority will be concluded if the lower limit of the two-sided 95% confidence interval (CI) for the ratio of hSBA GMTs against serogroup A between the liquid formulation and the licensed formulation is greater than 0.5.
    Protection of trial subjects
    All subjects were observed closely for at least 30 minutes following the administration of the vaccine, with appropriate medical treatment readily available in case of anaphylaxis. Vaccines were administered by qualified and trained personnel. Vaccines were administered only to eligible subjects that had no contraindications to any components of the vaccine. Safety was monitored for 6 months after vaccination.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: The number of subjects reported in the baseline period are the number vaccinated and therefore differ from the worldwide enrolled number.

    		 Percentages of subjects with a ≥4 fold rise in hSBA antibody titers for each of the N.meningitidis serogroups A, C,W and Y for each vaccine group, and between-group differences
    End point description
    The percentages of subjects with a ≥ 4-fold rise in post-vaccination hSBA (at Day 29 compared to Day 1) and associated 2-sided 95% Clopper-Pearson CIs were computed by group and for each N. meningitidis serogroups A, C, W and Y. A 4-fold rise in the hSBA titers is defined as: for individuals, whose pre-vaccination titers are < the LOD (limit of detection), the post-vaccination titers must be ≥ 4-fold the LOD or ≥ the LLOQ (lower of limit of quantitation) whichever is greater; for individuals, whose pre-vaccination titers are ≥ the LOD and ≤ the LLOQ, the post-vaccination titers must be at least four times the LLOQ; for individuals whose pre-vaccination titers are > the LLOQ, the post-vaccination titers must be at least four times the pre-vaccination

    End point description
    For each vaccine group the percentage of subjects with hSBA titer ≥8, and its associated two-sided 95% Clopper-Pearson CIs were computed for each of the N. meningitidis serogroups A, C, W and Y. Analysis was performed on the per protocol set for immunogenicity that includes subjects who received the vaccine, did not have any protocol deviation leading to exclusion, who were not excluded due to other reasons defined prior to unblinding or analysis and had available immuno data for any serogroup and time point considered.
