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   43861   clinical trials with a EudraCT protocol, of which   7284   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 provide clinical management and, if required, treatment to subjects who at the end of the HPV-008 study displayed normal cervical cytology but tested positive for oncogenic HPV infection or to subjects who were pregnant at the end of the HPV-008 study so that no cervical sample could be collected. - To report fatal serious adverse events (SAEs), SAEs related to study participation and SAEs related to a concurrent GSK medication in all subjects.
    Protection of trial subjects
    As with all injectable vaccines, appropriate medical treatment was always readily available in case of anaphylactic reactions following the administration of the vaccine in the HPV-008 (NCT00122681) study. For this reason, the vaccinee remained under medical supervision for 30 minutes after vaccination in the HPV-008 (NCT00122681) study.

No vaccine was administered in this extension study. Subjects received 3 doses of Havrix vaccine, administered intramuscularly, according to a 0, 1, 6-month vaccination schedule in the HPV-008 (NCT00122681) primary study.

    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: Out of the 2022 subjects enrolled, 19 did not fulfill eligibility criteria and were excluded, hence 2003 subjects started the study.

    Subjects with normal cervical cytology, who were found to be oncogenic HPV DNA positive in two subsequent tests, were referred to colposcopy. The result of the subjects’ last HPV-008 study visit was taken into account at Visit 1. Subjects with a single cervical cytology reading of ≥ atypical squamous cells of undetermined significance (ASC-US) positive for oncogenic HPV DNA were referred for colposcopy. Subjects with a single cervical cytology reading of ≥ low grade squamous intraepithelial lesion (LSIL) were referred to colposcopy, irrespective of their oncogenic HPV DNA test result.
