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   43693   clinical trials with a EudraCT protocol, of which   7245   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 ).

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    08 Sep 2003
    The core protocol amendment was issued on 08 Sep 2003 and concerned the following: • The number of participating sites and countries was extended due to a delay in recruitment in the prior N166 and N01057 studies. • Adverse events reported in postmarketing experience were added to protocol Section 2.2.4, Adverse Events in Clinical Studies (Section 16.1.1). • Some administrative changes were made to the protocol that did not alter the conduct of the study (eg, emergency contacts were updated and various edits made to sentences for clarification only).

    Interruptions (globally)
    Were there any global interruptions to the trial? No

    Limitations and caveats
