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 ).

    General information about the trial
    Main objective of the trial
    To demonstrate the non-inferiority of GSK Biologicals’ IPV vaccine as compared to the Chinese OPV vaccine in terms of the immune response to poliovirus type 1, 2 and 3, one month after the third vaccine dose. Non-inferiority in terms of immunogenicity to the three poliovirus antigens will be demonstrated if the upper limit of the 95% confidence interval (CI) on the group difference [Control Group minus Poliorix Group] in the percentage of seroprotected subjects is less than or equal to 10%.
    Protection of trial subjects
    The subjects were observed closely for at least 30 minutes, with appropriate medical treatment readily available in case of anaphylaxis following the administration of vaccines.

    Recruitment
    Recruitment details
    		 Of the 1101 enrolled subjects, one subject was not randomised and administered any vaccine as the parents of the subject refused to vaccinate their child after blood collection at Visit 1 and withdrew their consent.

    Pre-assignment
    Screening details
    		 During the screening the following steps occurred: check for inclusion/exclusion criteria, contraindications/precautions, medical history of the subjects and signing informed consent forms.

    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: Of the 1101 enrolled subjects, one subject was not randomised and administered any vaccine as the parents of the subject refused to vaccinate their child after blood collection at Visit 1 and withdrew their consent.
