Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   40977   clinical trials with a EudraCT protocol, of which   6698   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    D.8 Information on Placebo
    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Coronavirus disease-19 (COVID-19)
    E.1.1.1Medical condition in easily understood language
    COVID-19
    E.1.1.2Therapeutic area Diseases [C] - Virus Diseases [C02]
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is:

    -To assess non-inferiority of the humoral immune response against SARS-Cov-2 infection of different vaccines and adapted vaccine schedules in comparison with the reference schedules (‘group a’ of each brand)
    E.2.2Secondary objectives of the trial
    The secondary objectives are:

    1. Safety
    - To evaluate safety and reactogenicity of all different vaccination schedules

    2. Health Economics
    - To assess the impact of all different vaccination schedules on productivity

    3. Immunogenicity
    - To assess non-inferiority of the humoral immune response against SARS-Cov-2 infection of different vaccines and adapted vaccine schedules in comparison with the reference schedule (group a of each brand)
    - To analyse immunogenicity (T cell response) of all vaccine schedules ( in subset of participants)
    - To analyse immunogenicity (B cell response) of all vaccine schedules (in subset of participants)
    - To analyse biophysical characteristics (subclasses and glycosylation) of all vaccine schedules
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    No separate title / study is foreseen.

    However the T cell and B cell response immunogenicity off all vaccines schedules will be determined based on blood sampling of only a subset ( 30 out of 60 participants in each treatment group).

    - To analyse immunogenicity (T cell response) of all vaccine schedules (subset of participants)
    - To analyse immunogenicity (B cell response) of all vaccine schedules (subset of participants)

    E.5.2.1Timepoint(s) of evaluation of this end point
    1. Safety
    - Solicited AEs within 5 days after each vaccination
    - Unsolicited AEs until 14 days after each vaccination
    - MAAEs, AESIs and SAEs continuously throughout the study

    2. Health Economics
    - Within 5 days after each vaccination

    3. Immunogenicity
    - GMT of antibodies binding to the RBD of SARS-CoV-2 S protein at all available timepoints
    - GMT of neutralizing antibodies at 28 days post last study vaccine
    - T cell response at 28 days post last study vaccine
    - Memory B cell responses at 28 days post last study vaccine and day 364
    - SARS-CoV-2 spike (S) protein specific serum IgG glycosylation at timepoints selected on the basis of the results of the binding and neutralizing antibody data
