Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   35419   clinical trials with a EudraCT protocol, of which   5814   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    1) To demonstrate the immune lot consistency of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) conjugate vaccine with respect to serum bactericidal assay using human complement (hSBA) geometric mean titers (GMTs). 2) To demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, Y, and W following the administration of a single dose of MenACYW conjugate vaccine (pooled Lots 1 to 3) compared to those observed following the administration of a single dose of Menactra®.
    Protection of trial subjects
    Vaccinations were performed by qualified and trained study personnel. Subjects with allergy to any of the vaccine components were not vaccinated. After vaccination, subjects were also kept under clinical observation for 30 minutes to ensure their safety. Appropriate medical equipment was also available on site in case of any immediate allergic reactions.

    Geometric Mean Titers (GMTs) of Meningococcal Serogroups A, C, Y, And W Antibodies Following Vaccination With 3 Lots of MenACYW Conjugate [1]
    End point description
    Antibody titers against Meningococcal Serogroups A, C, Y, and W were measured by hSBA. Analysis was performed on Per-Protocol Analysis Set (PPAS) defined for accessing the ACYW immune response data for all subjects who received at least 1 dose of the study vaccine and had a valid post-vaccination serology result. The subjects who presented protocol deviations were excluded from per-protocol analysis set. Here, "n" signifies number of subjects with available data for each category, for each arm respectively.

    Notes
    [1] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.

    Geometric Mean Titers (GMTs) of Meningococcal Serogroups A, C, Y, and W Antibodies Following Vaccination With MenACYW Conjugate and Menactra® [30]
    End point description
    Antibody titers against Meningococcal Serogroups A, C, Y, and W were measured by hSBA. Analysis was performed on PPAS. Here, "n" signifies number of subjects with available data for each category, for each arm respectively.
    End point type
    Secondary
    End point timeframe
    Day 30 (post-vaccination)
    Notes
    [30] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: This endpoint was evaluated for reported arms only.

    Adverse events information
    Timeframe for reporting adverse events
    Adverse event (AE) data were collected from Day 0 up to Day 30 post-vaccination. Solicited Reaction (SR) data were collected from Day 0 up to Day 7 post-vaccination.
    Adverse event reporting additional description
    A SR was an AE that was prelisted (i.e.,solicited) in the electronic case report form (eCRF) and considered to be related to vaccination (adverse drug reaction). An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the eCRF (i.e.,solicited) in terms of symptom and/or onset post-vaccination. Safety Analysis Set.
