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   44334   clinical trials with a EudraCT protocol, of which   7366   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.

    2 Unable to take oral SZC drug mix
    3 Recipient of or scheduled date for living donor kidney transplant
    4 With a life expectancy of less than 6 months
    5 Any medical condition (including active, clinically significant infection) that, in the opinion of the investigator or sponsor, may pose a safety risk to the participant in this study, which may confound safety or efficacy assessments and jeopardise the quality of data, or may interfere with study participation
    6 Presence of cardiac arrhythmias or conduction defects that require immediate treatment
    7 QT interval corrected by the Fridericia method (QTcF) > 550 msec
    8 History of QT prolongation associated with other medications that required discontinuation of that medication

    14 Renal replacement therapy, including chronic haemodialysis and peritoneal dialysis
    15 Participation in another clinical study with an investigational product (IP) administered during the month before screening. Note: Participant vaccinated with COVID-19 vaccine whilst still under Emergency Use Utilisation will not be excluded from the study.

    (c) Intrauterine device (IUD)
    (d) Intrauterine hormone-releasing system (IUS)
    (e) Bilateral tubal occlusion
    (f) Vasectomised partner (vasectomised partner is a highly effective birth control method provided that partner is the sole sexual partner of the WOCBP participant and that the vasectomised partner has received medical assessment of the surgical success
    (g) Sexual abstinence: it is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the participant.
    21 For WOCBP only: Women who have a positive pregnancy test at screening OR women who are breastfeeding.
