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   42565   clinical trials with a EudraCT protocol, of which   7007   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) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The overarching aim is to gather knowledge about how Perfluoroalkyl substances (PFAS) affects the immune system. This aim is studied through immunological response after SARS-CoV-2-vaccination in adults.

    Primary research question: Does PFAS-exposure modify IgG-antibody production after SARS-CoV-2-vaccination?

    The question will be answered through quantification of IgG-antibodies against SARS-CoV-2 S-protein. Exposure to PFAS is quantified as the molar sum of the 16 PFAS-substances in serum, and stratified into low and high.
    Det övergripande syftet är att få ökad kunskap om hur PFAS påverkar immunsystemet. Specifikt studeras det immunologiska svaret vid vaccination mot SARS-CoV-2 bland vuxna.

    Primär frågeställning: Påverkar PFAS-exponering IgG-antikroppssvaret efter vaccination mot SARS-CoV-2?

    Utfallsmått: IgG mot SARS-CoV-2 S protein. Exponeringsmått: Summan av 16 PFAS-ämnen i serum, kategoriserad som antingen låg eller hög.
    E.2.2Secondary objectives of the trial
    Secondary research question: Does PFAS-exposure affects the cellular immune response after SARS-CoV-2-vaccination?

    This question will be answered through analyses of SARS-CoV-2 specific T-cell response. Exposure to PFAS is quantified as the molar sum of the 16 PFAS-substances in serum, and stratified into low and high.
    Sekundär frågeställning: Påverkar PFAS-exponering det cellulära immunsvaret mot SARS-CoV-2 S protein efter vaccination mot SARS-CoV-2?

    Utfallsmått: För T-celler bestäms SARS-CoV-2 specifika T-cellssvar. Exponeringsmått: Summan av 16 PFAS-ämnen i serum, kategoriserad som antingen låg eller hög.
