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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    15. Intention to change diet during the study,
    16. Known or suspected non-compliance with dietary phosphate restrictions,
    17. Known infection with human immunodeficiency virus (HIV),
    18. History of drug or alcohol abuse within 2 years before screening,
    19. Use of antacids containing aluminum or magnesium within 1 month before screening,

Serious medical condition, uncontrolled systemic disease (eg, poorly controlled diabetes mellitus, hypertension, active malignant disease within the last 5 years [except non-melanotic skin cancer] planned surgery including kidney transplantation during study, or suspected life-expectancy of <12 months per Investigator’s assessment),
    21. Inability to fully comprehend and/or perform study procedures (in the Investigator’s opinion),
    22. Receipt of any other investigational drug <30 days before the study or during the study.
