Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   39818   clinical trials with a EudraCT protocol, of which   6535   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    To compare the efficacy of Symbicort BA MDI 2x160/4.5 μg bid with that of Symbicort AC pMDI 2x160/4.5 μg bid by evaluation of: forced expiratory volume during first second (FEV1), 60 minutes post-dose and FEV1 pre-dose.
    Protection of trial subjects
    The Institutional review board (IRB)/independent ethics committee (IEC) for each study site approved the final clinical study protocol (CSP), including the final version of the informed consent form (ICF) and any other written information and/or materials that were provided to the patients. The PI at each centre ensured that each patient was given full and adequate oral and written information about the nature, purpose, possible risk, and benefit of the study. Each patient was notified that they were free to discontinue from the study at any time. Patients were given the opportunity to ask questions and were allowed time to consider the information provided. The PI at each centre ensured that each patient provided signed and dated informed consent before conducting any procedure specifically for the study. In patients below the age of consent, informed consent was obtained from both the patient and the patient’s parent/legal guardian

    Recruitment
    Recruitment details
    This was a multicentre trial conducted in 3 countries between November 2011 and August 2012.

    Pre-assignment
    Screening details
    The study consisted from an enrolment visit, a 2- week run in (standardization) period, randomization at visit 4, and 3 further visits (visits 5- 7) at 3, 7 and 12 weeks. During the 2-week-run-in period patients were treated with budesonide AC pMDI 2x160μg bid. After this period subjects were randomized to receive 1 of 3 doouble blinded treatments.

    Notes
    [1] - Assuming a standard deviation of 0.2 (for pre dose FEV1) on the log-scale and 60 patients/arm, the width of the confidence interval will extend 0.072 from the point estimate on the log-scale. The lower and upper limits of the CI for the ratio of effects will thus be obtained by multiplying the estimated ratio by 0.931 and 1.075, respectively.

    Asthma symptoms Score (Total)
    End point description
    The total score is calculated as sum of the morning and evening scores of each day and the treatment period mean score is defined as the mean of all total score recorded during the 12-week treatment period. Trt Avg=Mean total score of double-blind period values.(day/night score ranges from 0 to 3; 0=no asthma symptoms; 3= unable to do normal activities (or to sleep) due to asthma). Higher score represents worse outcome.

    Adverse events information
    Timeframe for reporting adverse events
    Adverse events were collected from the enrolment visit (visit 1) until follow-up (14 weeks after randomisation). Events occurring on or after first dose of study medication are included in the summaries.
    Adverse event reporting additional description
    1 patient from the Budesonide group has not taken any dose of the IP, so not included in the Safety population'. A total of 19 patients reported non-serious adverse events; 19 on Budesonide, 21 on Symbicort BA MDI, 24 on Symbicort pMDI.. Numbers for non-serious AEs in the reporting group table are based on the 2% threshold frequency.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    13 Oct 2011
    Clarify the timing of spirometry measurements in the morning. To allow the patients to undergo rescreen, so that at rescreening the patients would meet the time requirements for various elements by Visit 2 in the inclusion criteria without changing the patient characterisation in the study or jeopardizing patient safety.

    Interruptions (globally)

    Were there any global interruptions to the trial? No

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    No. of participants in the safety analysis set is (71 for all the group) as 1 patients from the Budesonide group has not taken any dose of the IP, so not included in the Safety population.
