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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    26 Oct 2015
    To broaden the targeted patient population the requirement for patients having been on a specific LABA dose of ≥9 µg and ≤18 µg formoterol or 100 µg salmeterol prior to Visit 1 is removed. Instead, it is specified that patients must be treated with a daily stable LABA dose 12 weeks prior to Visit 1 in order to be eligible. In addition, the calculations for FEV1, FVC and reversibility in FEV1 are clarified
    24 Feb 2016
    To better reflect the target population, the following criteria are changed: Inclusion Criterion 6 Inclusion Criterion 8 and Randomisation Criterion 2 xclusion Criterion 5 To facilitate trial logistics, Visit 1 assessments are allowed to be conducted over a window of 3 days. To be aligned with standard practice at some of the participating sites, reversibility testing at Visit 1, Visit 2 and Visit 3 may be performed using Salbutamol Dry Powder Inhaler 200-800 µg (changed from 200-400 µg) or 400 µg Salbutamol via pressurised metered dose inhaler with or without spacer. To allow adequate time for trial completion, time-lines for last subject randomised and last subject Last Visit have been extended with 1 quarter. The number of trial subjects will be reduced from the present 200 (100 in each arm) to 160 (80 in each arm). The effect of the change in the sample size will be an increase in the detectable difference between treatment arms from 80 µg to 89 µg for the average daily budesonide dose, and from 20% to 22% for treatment failures. These effects on the detectable difference in the study are considered acceptable. Lastly, minor typographical errors are corrected

    Interruptions (globally)

    Were there any global interruptions to the trial? No
