Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43932   clinical trials with a EudraCT protocol, of which   7307   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 on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.1.2System Organ Class 10014698 - Endocrine disorders
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To study in boys with constitutional delay of puberty, showing very early signs of puberty, whether treatment with the aromatase inhibitor letrozole promotes the progression puberty more efficiently than the current standard of care, low-dose testosterone therapy.
    Tutkia jouduttaako hoito aromataasi-inhibiittori letrotsolilla poikien murrosiän kehitystä tehokkaammin kuin tavanomainen, pieniannoksinen testoteronihoito. Tutkimuspopulaatio koostuu pojista joilla murrosikä on selvästi viivästynyt, mutta aivan ensimmäiset murrosiän merkit on havaittavissa.
    E.2.2Secondary objectives of the trial
    To study whether aromatase inhibitor treatment also results in faster post-treatment progression of puberty, as compared with low-dose testosterone; to study treatment effect on several sex steroid-responsive tissues/pathways, such as bone mineralization, lipid profile, markers of maturing spermatogenesis; to study the treatment influence on measures psychological well-being
    Tutkia johtaako aromataasi-inhibiittorihoito myös hoidon päättymisen jälkeen nopeampaan puberteetin etenemiseen kuin annettu perinteinen, pieniannoksinen mieshormonihoito; verrata aromataasi-inhibiittorihoidon ja tavanomaisen mieshormonihoidon vaikutuksia prosesseihin, jotka ovat sukupuolihormonisäätelyn alkaisia, kuten luuston mineralisaatio ja kehitys, lipidiprofiili ja kypsyvä siittiön muodostus. Lisäksi vertaamme testosteroni- ja aromataasi-inhibiittorihoidon vaikutuksia psyykkiseen hyvinvointiin.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Clinical and biochemical criteria: Age 14 yrs or more, mean testicular volume >2.5 mL and <4mL, serum testosterone <5 nM and the adolescent wants medical intervention. No signs of chronic diseases accounting for the delayed puberty.
    Biochemical criteria: As above, but serum testosterone >2 nM and normal serum DHEAS, even if the mean testicular volume is less than 2.5 ml.
    E.4Principal exclusion criteria
    Chronic diseases, primary hypogonadism, chromosomal anomalies, chronic medication that potentially adversely affects bone mineralization (excluding inhaled corticosteroid treatment).
    E.5 End points
    E.5.1Primary end point(s)
    The primary outcome measures are: testicular volume, urinary LH levels, and circulating hormone values reflecting the activity of the hypothalamic-pituitary-gonadal axis (especially, basal and GnRH-induced LH, FSH, testosterone, inhibin B, AMH levels). Changes in these parameters during treatment are compared between the testosterone and letrozole groups
    E.5.1.1Timepoint(s) of evaluation of this end point
    After all patients in the randomized study have completed the 12 months of follow-up.
    E.5.2Secondary end point(s)
    The secondary end points are changes in
    bone mineral density and structure as evaluated by dual-energy x-ray absorptiometry and peripheral quantitative CT; measures of social functioning, body image and self esteem; lipid profile; markers of maturing spermatogenesis
    E.5.2.1Timepoint(s) of evaluation of this end point
    After all patients in the randomized study have completed the 12 months of follow-up.
