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   36600   clinical trials with a EudraCT protocol, of which   6044   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.

    Recruitment
    Recruitment details
    This was a repeat-dose, open-label randomized, incomplete block design study in pediatric participants with asthma, aged 4-11 years to compare systemic exposure and pharmacodynamics of Advair HFA (A), Advair DISKUS (B), and Advair HFA with Aerochamber Plus Spacer (C) in two treatment periods, with a follow-up period within 24 hours post last dose.

    Pre-assignment
    Screening details
    Following Baseline assessments, participants received Advair HFA 45/21 microgram (µg) (two inhalations), Advair DISKUS 100/50 µg (one inhlation), or Advair HFA with Aerochamber Plus Spacer 45/21 µg (two inhalations) twice daily for 21 days, in accordance with the treatment sequence to which they were randomized (AB,BA,AC,CA,BC,or CB).

    End point description
    Participants' blood samples were collected and analyzed for SC levels. The serum cortisol weighted mean, calculated by dividing the area under the concentration curve (AUC) over the 0-12 h period by the sample collection time interval, was determined at Baseline and at the end of each treatment period. Only participants data available at the analysis time point were analyzed (represented as n=X, X, X in category title. Pharmacodynamic (PD) parameter population was defined as all participants who received treatment during both periods and for whom PD parameters were derived for both periods.

    Maximum mean change from Baseline of the QT Interval Corrected According to Fridericia's Formula (QTcF) at 9 hours post-dose
    End point description
    Twelve-lead electrocardiograms (ECGs) were performed to measure QT interval corrected according to Fridericia's formula (QTcF) at Baseline, pre-dose and 15 minutes (min), 45 min, 1.5 hours (h), 3h, 6 h and 9 h post-dose on Day 21 of each treatment period and the maximum values for QTcF were derived during the 0-9 h period. Baseline was defined as the derived parameter from the Baseline assessment. The data are presented as adjusted means of the maximum QTcF. Only participants data available at the analysis time point were analyzed (represented as n=X, X, X in category title).

    Weighted mean change from Baseline for supine DBP at 9 hours post-dose
    End point description
    Blood pressure (BP) measurement included SBP and DBP. DBP was recorded at screening, prior to dosing, and at 15 min, 45 min, 1.5,2, 4, 6 and 9 h post-dose on Day 21 of the each treatment period. Weighted mean (WM) was derived by calculating the AUC, and then dividing by the relevant time interval. Baseline was defined as the derived parameter from the Baseline assessment. The data are presented as adjusted mean of WM DBP. Only participants data available at the analysis time point were analyzed (represented as n=X, X, X in category title).

    Advair HFA
    Reporting group description
    Participants were randomized to one of the 6 possible treatment arms (AB, BA, AC, CA, BC, or CB): two inhalations of ADVAIR HFA 45/21 µg , which was supplied as a HFA-propelled 120-actuation metered dose inhaler (MDI) desgined to deliver 45 µg of fluticasone propionate (FP) and 21 µg of salmeterol twice daily (BID) for 21 days (on outpatient basis except on Day 21) along with either Advair HFA with Aerochamber Plus Spacer or Adavir DISKUS. After this treatment period 1, participants received a repeat dosing of the same sequence for 21 days without any washout period.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    12 Sep 2006
    The purpose of this amendment was to change the study design to include a third arm to evaluate the systemic exposure and pharmacodynamics of ADVAIR HFA following administration using the Aerochamber plus Spacer. GlaxoSmithKline plans to use the Aerochamber Plus Spacer in a 12-week safety study (SFA 106484). Since systemic exposure of an inhaled drug product can vary gently depending on the mechanism of administration, the FDA recommended an assessment of the difference of systemic exposure with and without a spacer to be included in this clinical pharmacology protocol. This protocol has also been modified to remove inconsistencies in study procedures and to make clarification to the inclusion/exclusion criteria.
    09 Nov 2006
    Based on feedback at a recent investigators meeting, the inclusion criteria regarding minimum weight for eligibility in this study will be amended to facilitate in the 4 to 7 years age range. The protocol states that 1/3 of the subjects must be ≤7 years of age. However, the current weight restriction would make it difficult to reach this enrollment target. Furthermore, this amendment will clarify exclusion criteria regarding inhaled corticosteroid use.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
