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   37191   clinical trials with a EudraCT protocol, of which   6121   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to evaluate whether vitamin D supplementation with 20,000 weekly over 12 weeks significantly increases TT levels when compared to placebo.
    E.2.2Secondary objectives of the trial
    In addition, we also aim to test the hypothesis that vitamin D supplementation improves endocrine parameters (e.g. FT, SHBG, LH, FSH, and estradiol), metabolic parameters as well as sexual, physical and psychological symptoms.
    Moreover, we will evaluate whether vitamin D supplementation with 20,000 weekly over 12 weeks improves endocrine parameters (e.g. TT, FT, SHBG, LH, FSH, and estradiol) and metabolic parameters when compared to placebo in eugonadal men.
    Further, we will perform genotyping of vitamin D-related polymorphisms to evaluate a possible genetic background of the association of vitamin D with androgen levels. In addition, gene expression analyses of relevant candidate genes in association with pathways of vitamin D and testosterone will be performed at each visit in order to analyze functional changes during vitamin D treatment.
