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   38964   clinical trials with a EudraCT protocol, of which   6398   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    subcutaneous immunotherapy in allergic rhinits (AR) patients with allergies to birchpollen
    E.1.1.1Medical condition in easily understood language
    Allergic rhinitis patients with allergies to birchpollen

    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 evaluate whether 2.5 µg VD3 analogue (Zemplar® – Abbvie) in multiple subcutaneously administered doses induces a more favourable (read: anti-inflammatory) systemic immune modulation both in general parameters and allergen-specific responses in birch pollen allergic subjects more resembling the response observed in gender, age and study site matched healthy control subjects. To this end, the primary outcome of the study is the observed IL-10 production as marker of the induction of a more anti-inflammatory systemic immune response, at start, at 4 weeks of treatment and follow-up, comparing birch pollen allergic subjects and healthy controls in a placebo-controlled design. The target is a statistically significant increase in IL-10 production upon polyclonal and/or allergen specific stimulation in allergic subjects, more resembling the response expected to be seen in healthy controls.
    E.2.2Secondary objectives of the trial
    1) The reactivity, cellular composition and detailed characterization of antigen-presenting cell (APC) and T cells in the PBMC, using proliferation, detailed cell surface marker expression, and cytokine production (beyond IL-10) in response to polyclonal and allergen-specific stimulation.
    2) To evaluate the safety and tolerability, both systemically and locally, of the VD3 analogue Zemplar® administered by the subcutaneous route during each treatment visit and at the follow up visit compared to placebo. To evaluate blood safety biochemistry/haematology parameters, urinalysis, vital signs and ECG, lung function before and after treatment with 2,5 μg VD3 analogue (Zemplar®) in multiple subcutaneously administered doses compared to placebo.

    E.5.2Secondary end point(s)
    • Comparison of ΔIL-10 between allergic subjects and healthy controls
    • Cellular composition of PBMC with respect to Th1, Th2, Th17, Th22, and Treg cells, B cells, and antigen-presenting cells (APC)
    • PBMC proliferation and cytokine production in response to allergen (Bet v 1)
    • PBMC proliferation and cytokine production in response to polyclonal stimuli (αCD3/αCD28)
    • Intracellular cytokine measurements in response to PMA/ionomycin
    • Blood safety biochemistry/haematology parameters, urinalysis, vital signs and ECG, lung function will be determined at baseline and at the follow up visit.
    • Safety and tolerability (local and systemic reactions / [serious] adverse events) of the VD3 analogue Zemplar® administered via the subcutaneous route will be evaluated at each treatment visit and the follow up visit.
    E.5.2.1Timepoint(s) of evaluation of this end point
    Safety measurements and vital signs will be done at each visit. ECG and lungfunction will be done at the randomisation visit and at the follow up visit. urinalysis will be done at screening and follow up.
    30 minutes after each injection the injection location will be checked.
