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   43839   clinical trials with a EudraCT protocol, of which   7280   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 endpoint will be the change in the Pain Intensity Score from baseline to Week 12.
    The Pain Intensity Score, related to the CRPS-affected limb, will be determined from current pain intensity ratings, captured in an electronic diary, using an 11-point numerical rating scale (NRS). Subjects will be asked to rate their current CRPS-related pain intensity twice daily, once in the morning and once in the evening. Subjects rate their pain on this scale from 0 = “no pain” to 10 = “pain as bad as you can imagine”.
    The Baseline Pain Intensity Score will be calculated as the average of 14 current pain intensity ratings obtained over the 7-day baseline pain assessment phase prior to allocation to IMP, starting from the evening of Day -7 and concluding on the morning of Day 1 prior to IMP administration. At least 10 pain intensity ratings must be available for determination of the Baseline Pain Intensity Score. The Week 12 Pain Intensity Score will be determined in a similar manner (i.e., calculated from ratings obtained during the week prior to Visit 8, culminating with the morning rating on the day of Visit 8). All available ratings (of the 14 possible ratings in this time period) will be used in the calculation.
    All pain intensity ratings for the primary endpoint will be in reference to the CRPS-affected limb (or most painful limb at the time of screening if more than 1 limb is affected by CRPS).
