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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    This dose-ranging study evaluated an investigational vaccine with the following objectives: (1) To demonstrate that the vaccine is well-tolerated in women (2) To evaluate immune responses in women who are between 16 and 23 years of age at enrollment. The primary hypothesis for the study are as follows: 1) the geometric mean titers (GMTs) at 4 weeks Postdose 3 for each of the Human Papillomavirus (HPV) Types 6, 11, 16, 18 for participants receiving V502 vaccination are non-inferior to those induced by qHPV vaccine (Gardasil), and 2) V502 administered to 16 to 23-year old women is generally well-tolerated.
    Protection of trial subjects
    This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research.

    Geometric Mean Titer (GMT) of Anti-HPV 6 Antibody
    End point description
    Anti-HPV Type 6 antibodies were measured by a Competitive Luminex Immunoassay (cLIA). The unit of measure was milli Merck Units/mL (mMU/mL). The seropositive cut-off threshold for this assay is defined as 20 milli Merck U/mL. Participants analyzed included those who were not protocol violators, received all 3 vaccinations, were seronegative at Day 1 and polymerase chain reaction (PCR) negative from Day 1 through Month 7 for the relevant HPV Type, and had a Month 7 serum sample collected and tested for anti-HPV 6 antibody.

    End point description
    An adverse experience (AE) is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the sponsor's product, whether or not considered related to the use of the product. Any worsening of a preexisting condition which is temporally associated with the use of the sponsor's product is also an AE. Participants used the Vaccination Report Card to record injection-site AEs. The participants analyzed included those who received at least one vaccination and had follow-up.
