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   43857   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 ).

    General information about the trial
    Main objective of the trial
    To demonstrate improvement of peripheral airway resistance (R5-R20) from baseline with fluticasone/formoterol breath actuated inhaler (BAI).
    Protection of trial subjects
    All subjects were provided with oral and written information describing the nature and duration of the study, its purpose, the procedures to be performed, the potential risks and benefits involved, and any potential discomfort. Each subject was given a copy of the PIS and ICF. The subject was asked to sign and date an ICF prior to any study-specific procedures being performed.
    Background therapy
    Subjects already on Seretide Accuhaler 250/50 µg BID at screening underwent a run-in period of 2 weeks during which they continued their Seretide Accuhaler medication. Subjects on equivalent /higher doses of other ICS-LABAs or higher dose of Seretide at screening were also eligible to undergo a run-in of 4 weeks on Seretide Accuhaler 250/50 µg BID. As well as receiving IMP, all subjects were also provided with Ventolin (salbutamol) as rescue medication at the start of the run-in period to be used as needed during the run in and treatment periods of the study at a dose of up to 8 puffs/day.
    Evidence for comparator
    Relvar Ellipta was chosen as a comparator product because it is an approved ICS-LABA combination therapy. Relvar Ellipta is a dry powder inhaler (DPI).

    Notes
    [1] - The roles blinded appear inconsistent with a simple blinded trial.
    Justification: The study was designed as assessor-blind due to the challenges associated with developing a placebo device for Relvar Ellipta. Nonetheless, because of the objective nature of the primary and key secondary efficacy variables, the subject’s knowledge of their treatment was unlikely to influence the key study outcomes. Furthermore, use of two different devices which require different inspiratory techniques may have created patient confusion leading to more handling errors.

    Adverse events

    Close Top of page
    Adverse events information
    Timeframe for reporting adverse events
    Events were recorded from the point at which the Informed Consent was signed until 14 days after the subject left the study. This included new AEs that were reported in the 14 days following the subject’s completion/discontinuation visit.
    Adverse event reporting additional description
    Only treatment emergent AEs were analysed. A treatment emergent AE was defined as any AE with an onset date on or after the first dose of IMP if the AE was absent before the first dose of IMP, or worsened after the first dose of IMP. This also included AEs with an onset date up to and including 7 days after the last dose of IMP.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    29 Apr 2016
    Protocol Amendment No. 1 was required to remove Functional Respiratory Imaging (FRI) as a secondary objective from the protocol. The HDCT scans at Visits 2, 4, 5 and the associated endpoints and analyses were removed from the protocol. This amendment was implemented as the risk:benefit ratio for exposing subjects recruited under this protocol to radiation associated with HDCT scans was considered unfavourable. This decision was made following review of the study protocol by the UK research ethics committee (Cambridge East Research Ethics Committee).
    05 Jan 2017
    Protocol Amendment No. 2 was intended to address recruitment challenges in the study without detriment to the scientific quality of the study. The current recruitment rate had been significantly slower than anticipated and this amendment was intended to address the issues which were found to be impacting on this; in this amendment the screening and randomisation inclusion value of IOS R5-R20 were lowered, a second IOS was allowed at screening to mitigate issues associated with subjects failing to withhold medication per the protocol instructions, and the sample size was reduced.
