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   44237   clinical trials with a EudraCT protocol, of which   7338   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.5 End points
    E.5.1Primary end point(s)
    The primary efficacy variable will be the mean latency to persistent sleep (LPS) via PSG, over Nights 1 and 2 of double-blind treatment.

    The secondary efficacy variables will be mean LPS via PSG over Nights 15 and 16, and over Nights 29 and 30.
    Additional secondary efficacy variables will be total sleep time (TST), sleep efficiency, wake time after persistent sleep, number of awakenings after persistent sleep as determined by PSG. Subjective assessment of treatment outcomes will be captured using PSQ-IVRS, sSL, sTST, subjective sleep quality, subjective awake time, subjective number of awakenings, and subjective ease of falling back to sleep as determined by PSQ/sleep diary.
    Additional parameters will be recorded using the digit symbol substitution test, memory recall test, and visual analog scale.
    Measures of LPS will be used to assess rebound insomnia upon single-blind placebo run-out period. The subjective morning alertness and ability to concentrate will be captured via PSQ. The Tyrer Benzodiazepine Withdrawal Symptom Questionnaire will be used to assess subjective effects of withdrawal from study medication.
    Sleep architecture variables include percentage of TST in rapid eye moment (REM) sleep, stage 1, 2 and 3/4 nonrapid eye movement sleep, and latency to REM as determined by PSG.
    Safety variables will include adverse events, laboratory tests, vital signs, electrocardiogram results, and physical exam findings.
