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   43870   clinical trials with a EudraCT protocol, of which   7289   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.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The main objective is to investigate whether withdrawal of paracetamol when used together with strong opioids provides inferior pain control compared to continuous use of paracetamol together with strong opioids.
    E.2.2Secondary objectives of the trial
    - Does placebo compared to paracetamol in cancer pain patients already on strong opioids result in more opioid-related side effects?
    - Does paracetamol withdrawal in cancer pain patients already on strong opioids influence patient’s global impression of change?
    - Does placebo compared to paracetamol in patients with cancer-related pain already on strong opioids change patients’ opioid consumption?
