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   43861   clinical trials with a EudraCT protocol, of which   7284   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.

    Adverse events information
    Timeframe for reporting adverse events
    Treatment-emergent adverse events (TEAEs) and serious adverse events (TESAEs) were collected from the time of study drug administration until 30 days after the last dose of study drug (up to 16 weeks).
    Adverse event reporting additional description
    TEAEs and TESAEs are defined as any AE or SAE with an onset date that is after the first dose of study drug until 30 days after the last dose of study drug and were collected whether elicited or spontaneously reported by the participant.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    16 Sep 2015
    The main purpose of this amendment was to update the introduction and benefit/risk sections with newly available safety and efficacy information, clarify that all patient populations with severe renal-impairment were to be included, with the exception of GT3 noncirrhotic treatment-experienced subjects and GT3 cirrhotic subjects; and clarify assessments of concomitant medications.
    17 Mar 2016
    The main purpose of this amendment was to update inclusion (clarify contraception use during the study) and exclusion criteria (allow subjects on peritoneal dialysis, organ transplant if subject was stable without immunosuppressive medications); and clarify study procedures.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
