  • 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   36818   clinical trials with a EudraCT protocol, of which   6079   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).

    General information about the trial
    Main objective of the trial
    The main objective was to assess the efficacy (as measured by the change from baseline in prebronchodilator [preBD] percent-predicted forced expiratory volume in 1 second [FEV1]) of JNJ 38518168 compared with placebo in subjects with eosinophilic persistent asthma that is inadequately controlled despite current treatment (inhaled corticosteroids [ICS] with or without long-acting beta-2-agonist [LABA], montelukast).
    Protection of trial subjects
    The safety assessments included clinical laboratory tests (hematology, serum chemistry and urinalysis), spirometry, electrocardiogram (ECG), vital signs and physical examinations. Adverse events were assessed throughout the study.

    FEV1 is the amount of air that can be exhaled in one second. FEV1 will be measured by spirometry. A positive change from baseline in FEV1 indicates improvement in lung function. The modified intent-to-treat (mITT) analysis set included all randomized subjects who received at least one dose (partial or complete) of study agent and had at least 1 post treatment efficacy measurement.

    Change From Baseline in Asthma Control Questionnaire (ACQ) at Week 16
    End point description
    ACQ is used to evaluate asthma control, the full range of clinical impairment (well controlled to life threatening) for the participant with asthma. There are 7 questions (5 for symptoms [night-time awakenings, morning symptoms, limitation of activities, shortness of breath, and wheezing], use of daily rescue bronchodilator, and percent predicted forced expiratory volume value). All 7 items are scored on a 7-point scale (0 = good control, 6 = poor control), with the mean score as an overall summary score. The recall period is 7 days. Higher scores indicate worsening. The mITT analysis set included all randomized subjects who received at least one dose (partial or complete) of study agent and had at least 1 post treatment efficacy measurement. Here, ‘n’ signifies number of subjects analyzed for this endpoint at given timepoint.

    Change From Baseline in Weekly Average of Daytime Asthma Diary Symptom Score at Week 16
    End point description
    Asthma symptom diary score is an index to access the severity of asthma related symptoms. The symptoms are wheezing, coughing, chest tightness and trouble breathing. The severity of each symptom is assessed by a 5-point ranking scale (0 = no symptom, 1 = mild, 2 = moderate, 3 = severe, 4 = extremely severe). Subjects are instructed to score and document their symptoms through e-diary every morning and evening. Daytime asthma symptom score is defined as the average of the four symptom scores collected in evening diaries. The modified intent-to-treat (mITT) analysis set included all randomized subjects who received at least one dose (partial or complete) of study agent and had at least 1 post treatment efficacy measurement.

    Change From Baseline in Weekly Average of Number of Puffs in a day That Rescue Medication was Used at Week 16
    End point description
    The weekly average of number of puffs in daytime (nighttime) that rescue medication is used for a particular visit (excluding Baseline visit) is calculated as sum of the weekly average of number of puffs in daytime and nighttime the week (7-day period) prior to the visit. The 7-day period does not include the day of visit. If less than 4 data points are available for daytime (nighttime) rescue medication use, the daytime (nighttime) assessment was considered missing. The modified intent-to-treat (mITT) analysis set included all randomized subjects who received at least one dose (partial or complete) of study agent and had at least 1 post treatment efficacy measurement.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    08 Mar 2013
    The amendment includes the following substantial changes: Based upon preliminary pharmacokinetic (PK) results from the 38518168ARA1003 drug-drug interaction (DDI) study with ketoconazole (a potent CYP3A4/Pgp inhibitor), information regarding DDIs, criteria for subject enrollment, and the list of prohibited medications were updated, allowing greater flexibility in subject enrollment and choice of concomitant medications; Total Nasal and Ocular Symptom Score (TNOSS) assessment was removed from Screening Visit 2 as this assessment was not required at this time point; clarification of wording for primary endpoint and hypothesis; clarification of statistical sections; clarification of repeat testing for induced sputum; clarification added regarding dosing of study agent with water; text regarding epigenetic testing was added; clarification added on ferritin unit values and text on retesting to inclusion criterion #10; clarification added on background inhaled corticosteroids (ICS), long-acting beta-2-agonist (LABA), and montelukast use for stratification; added clarifying text on electrocardiogram (ECG) that if the repeat QTcF continues to be above 480 msec based on the central cardiologist's overread, the study medication should be discontinued; list of substrates of CYP2C8 was revised to include montelukast, which was recently identified as a CYP2C8 substrate in clinical studies; added clarifying text for definition of asthma exacerbations as an emergency room visit because of asthma requiring treatment with systemic corticosteroids for at least 3 consecutive days; a criterion was added excluding women from donating eggs.
