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.

    General information about the trial
    Main objective of the trial
    To assess the effects of BGF MDI and GFF MDI on specific image-based airway volumes and resistance in subjects with moderate to severe COPD following chronic twice daily (BID) dosing after approximately 4 weeks of treatment.
    Protection of trial subjects
    Ventolin HFA was provided throughout the study for subjects to take as needed for relief of symptoms.

    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: According to the protocol, the primary analysis in this study was not a comparison between treatments, it was a comparison to baseline within each treatment. Therefore, no statistical analysis is included in this form as to only name a single treatment arm for each analysis generated validation errors. The estimates and confidence intervals for each comparison to baseline are however provided.
