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   43976   clinical trials with a EudraCT protocol, of which   7312   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.

    End point description
    The Functional Assessment of Cancer Therapy-Prostate (FACT-P) will be used to measure health related quality of life (HRQL) in men with prostate cancer. It consists of 4 subscales (physical, emotional, functional and social/family well-being) plus a 12-item prostate-specific module, the PCS subscale, which highlights concerns specific to participants with prostate cancer. Each question in the FACT-P questionnaires has a choice of 5 responses, “Not at all”, “A little bit”, “Somewhat”, “Quite a bit” and “Very much”. The scores range from 0 (“Not at all”) to 4 (“Very much”) for positively phrased questions. Negatively phrased questions have a reverse scoring, from 0 (“Very much”) to 4 (“Not at all”). n = Number of participants included in analysis Note: None of the 10 participants at Baseline answered the questionnaire at Cycle 1 Day 1. Therefore, related statistics were not derived for this timepoint.
