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   42330   clinical trials with a EudraCT protocol, of which   6971   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

    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
    Vaccination against SARS-CoV-2 in patients with immunosuppressive therapy or immunodeficiencies
    E.1.1.1Medical condition in easily understood language
    Vaccination against Covid-19 in patients who are under medication which suppresses the immune system or have immunodeficiencies
    E.1.1.2Therapeutic area Diseases [C] - Immune System Diseases [C20]
    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 study aims to investigate A) the humoral and cellular immune responses after a second boost vaccination against SARS-CoV-2 in adult patients treated with immunosuppressive therapy who did not show response to the first two vaccinations with an mRNA vaccine.
    To assess the immunogenicity to a third vaccination mRNA-SARS-CoV-2 vaccine (Biontech/Pfizer or Moderna) compared to a vector SARS-CoV-2 (AstraZeneca) vaccination as a second boost in patients with immunosuppressive therapy.
    B) To compare the immunogenicity to a third vaccination with a mRNA-SARS-CoV-2 vaccine as a second boost in immunocompromised patients and healthy controls who developed insufficient titres of antibodies (< 1500 U/ml) after the standard vaccination by measuring quantitative antibody levels by spike-protein-based assay. The level of antibody increase will be compared between the two groups.
    E.2.2Secondary objectives of the trial
    • Cellular immunogenicity of the third mRNA SARS-CoV-2 vaccination will be compared to patients receiving a vector vaccination as second boost in immunocompromised patients without prior humoral response. Further, T cell responses will be compared in immunocompromised patients as well as healthy controls before and after a second mRNA boost vaccination. T cell proliferation will be assessed, and T-cell cytokine expression will be measured using flow-cytometry following in vitro stimulation of peripheral blood mononuclear cells (PBMCs) with SARS-CoV-2 specific antigens.
    • Comparison of total antibody titre after the second boost as well as absolute and relative change in antibody titre before and after the second boost in immunosuppressed patients versus the healthy controls
    • To assess safety of a second boost vaccination.
    • To qualitatively evaluate the influence of a second boost vaccination on underlying disease treated with immunosuppressive therapy.

    E.5 End points
    E.5.1Primary end point(s)
    A) Difference in SARS-CoV-2 antibody seroconversion rate by week 4 after vaccination boost at baseline between 3rd mRNA SARS-CoV-2 (Biontech/Pfizer or Moderna) and vector SARS-CoV-2 vaccine (AstraZeneca).
    B) The efficacy of a 3rd mRNA boost vaccination in immunocompromised patients with inadequate humoral response (antibody titre <1500U/ml) to standard SARS-CoV-2 vaccination will be compared to low titre heathy controls by assessing the difference in antibody titre change before and after a second boost between the two groups.
    E.5.1.1Timepoint(s) of evaluation of this end point
    4 weeks after SARS-CoV-2 vaccination
    E.5.2Secondary end point(s)
    The secondary endpoints of this study are:
    • Overall SARS-CoV-2 antibody seroconversion rate by week 4 after vaccination boost in patients with no detectable antibodies at baseline
    • Antibody concentrations including neutralizing antibodies against SARS-CoV-2 4 weeks after vaccination boost at baseline
    • Difference in absolute and relative change of antibody titres before and after second mRNA vaccine boost between patients and healthy controls
    • Effect of disease entity on SARS-CoV-2 antibody seroconversion rate and titre changes by week 4 after vaccination boost at baseline
    • Effect of immunosuppressive medication and steroids on SARS-CoV-2 antibody seroconversion rate/titre change by week 4 after vaccination boost at baseline
    • Effect of patient characteristics (age, gender, time between second and third vaccination) on seroconversion rate/titre change by week 4 after vaccination boost at baseline
    • Evaluation of cellular immunity before and one week after the vaccination in all groups
