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   43845   clinical trials with a EudraCT protocol, of which   7282   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.

    Clinical Trial Results:
    A phase I/II, double-blind, randomized, multicentre study to evaluate the safety and immunogenicity of new formulations of GlaxoSmithKline Biologicals’ DTPa-HBV-IPV/Hib vaccine when administered to healthy infants as a primary vaccination course at 2, 3 and 4 months of age.

    General information about the trial
    Main objective of the trial
    To demonstrate that the immunogenicity of at least one DTPa-HBVIPV/Hib formulation is non-inferior to the licensed formulation in terms of seroprotection rates to diphtheria, tetanus, hepatitis B and PRP antigens and in terms of antibody geometric mean concentrations (GMCs) for pertussis antigens one month after the third dose of the primary vaccination.
    Protection of trial subjects
    As with all injectable vaccines, appropriate medical treatment was readily available in case of anaphylactic reactions following the administration of the vaccine. For this reason, the vaccine remained under medical supervision for 30 minutes after vaccination.

    Blinding implementation details
    This study is a double-blind study in which the parent(s)/LAR(s) and investigators were unaware of the treatment administered. The laboratory in charge of the laboratory testing was blinded to the treatment, and codes were used to link the subject and study (without any link to the treatment attributed to the subject) to each sample.

    Number of subjects with anti-hepatitis B (anti-HBs) antibody concentration equal to or above (≥) 10 and 100 milli-International units per milliliter (mIU/mL).
    End point description
    A seroprotected subject was defined as a vaccinated subject who had anti-HBs antibody concentrations ≥ 10 mIU/mL. A decrease in the specificity of the anti-HB enzyme-linked immunosorbent assay (ELISA) had been observed in some studies for low levels of antibody (10-100 mIU/mL). All the available blood samples initially tested with ELISA were re-tested using the Chemi Luminescence Immuno Assay (CLIA) approved by the US Food and Drug Administration (FDA). The table shows updated results following partial or complete retesting/reanalysis.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    23 Feb 2011
    Due to slow recruitment, the study from now on will also be conducted in countries outside Europe. In order to allow recruitment in other countries, hepatitis b vaccination at birth will now be allowed and preferred route for recording temperature in this study will be axillary or rectal. In countries outside Finland, Prevenar 13 will not be associated with any clinical endpoints. Due to the multi-country approach, one of the statistical methods has been updated.
    19 Sep 2011
    The protocol is being amended to allow a preliminary descriptive analysis of the available immunogenicity data. In order to ensure validity of the study results and integrity of data, the preliminary analysis will be performed by a statistician not otherwise involved with the conduct of the study, and results will be shared only with a restricted group of individuals within GSK Biologicals. The study team and the investigators will remain blinded until the study end. The 95% confidence interval (CI) criteria in the primary objectives have been updated to 97.5% CI to reflect the adjustment for multiplicity planned in the sample size consideration and to align to the wording used in the Booster DTPAHBV-IPV-125 (114843) protocol. A sequential list will be generated to allocate treatment numbers to the Prevenar 13 doses. The same has been reflected in the Randomization of supplies section. At the discretion of GSK Biologicals, pneumococcal testing may be done at a GSK Biologicals laboratory or the World Health Organisation (WHO) reference laboratory. Since the 22F-inhibition ELISA assay used at the WHO reference laboratory has a different assay cut-off, different thresholds are mentioned in the statistical analysis description. The threshold for the 22F-inhibition non-GSK ELISA assay performed at the WHO reference laboratory is 0.35 μg/ml.
