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 ).

    Clinical Trial Results:
    A phase III, single group, open study to assess the immunogenicity, safety and reactogenicity of GlaxoSmithKline (GSK) Biologicals’ 10-valent pneumococcal conjugate vaccine in Mexico when co-administered with GSK Biologicals’ Infanrix hexa (DTPa-HBV-IPV/Hib) vaccine as a 3-dose primary immunization course at 2, 4 and 6 months of age and GSK Biologicals’ Rotarix vaccine (HRV) as a 2-dose primary immunization course at 2 and 4 months of age.

    General information about the trial
    Main objective of the trial
    To compare the immunogenicity of GSK Biologicals’ 10-valent pneumococcal conjugate vaccine in Mexico, one month post dose III, when co-administered with GSK Biologicals’ Infanrix hexa and GSK Biologicals’ Rotarix vaccines, to the immune responses as observed in the pivotal non-inferiority, lot-to-lot consistency study 10PN-PD-DIT-001 in Europe.
    Protection of trial subjects
    All subjects were supervised closely for at least 30 minutes following vaccination with appropriate medical treatment readily available. Vaccines were administered by qualified and trained personnel. Vaccines were administered only to eligible subjects that had no contraindications to any components of the vaccines. The subject’s parents/guardians were instructed to contact the investigator immediately should their child manifest any signs or symptoms they perceived as serious. Subjects were followed up for any safety event from the time the subject consented to participate in the study until she/he was discharged.

    Antibodies assessed for this comparison endpoint were antibodies against the vaccine pneumococcal serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F (ANTI-1, -4, -5, -6B, -7F, -9V, -14, -18C, -19F and -23F). The seropositivity cut-off of the assay was an antibody concentration ≥ 0.05 µg/mL. Studies compared as regards results for antibody concentrations against 10Pn pneumococcal vaccine serotypes were studies 10PN-PD-DIT-029 (this study) and 10PN-PD-DIT-001 (105553) (EuDRA CT number: 2005-003300-11) via a comparison of 10Pn-001 Group over Synflorix Vaccine Group.

    End point description
    Antibodies assessed for this comparison endpoint were antibodies against protein D (anti-PD). The seropositivity cut-off of the assay was an antibody concentration ≥ 100 enzyme-linked immunosorbent assay (ELISA) units per millilitre (EL.U/mL). Studies compared as regards results for Anti-PD antibody concentrations were studies 10PN-PD-DIT-029 (this study) and 10PN-PD-DIT-001 (105553) (EuDRA CT number: 2005-003300-11) via a comparison of 10Pn-001 Group over Synflorix Vaccine Group.
