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   43718   clinical trials with a EudraCT protocol, of which   7255   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 ).

    End point title
    		 Annual Asthma Exacerbation Rate (AER) [1]
    End point description
    The annual asthma exacerbation rate (AER) in participants, was calculated as the total number of observed exacerbations in each group up to week 53, divided by total duration of person-year follow-up in each group. An asthma exacerbation defined as a progressive increase of asthma symptoms (cough, wheeze, chest tightness, and/or shortness of breath) that does not resolve after the initiation of rescue medications and remains troublesome for the participant resulting in either 1) use of systemic corticosteroids (tablets, suspension or injection) or increase of a stable systemic maintenance dose for a duration of at least 3 days as prescribed or administered by the investigator or healthcare provider; or 2) participant initiation of systemic corticosteroids for a duration of at least 3 days. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. The intent-to-treat (ITT) population included all participants who were randomized into the study.

    End point description
    Pre- and post-bronchodilator FEV1 and FVC at clinic visits (morning) were measured. FEV1 was the maximal volume of air exhaled in the first second of a forced expiration from a position of full inspiration. FVC was the volume of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. Ratio of FEV1/FVC was analysed. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. The ITT population included all participants who were randomized into the study. Here "n" signifies participants who were evaluable for this measure for the specified time point for each arm, respectively.

Rescue medication use questions were first assessed using a dichotomous response option (YES/NO). If the participants reported YES, there was a subsequent question about the number of times rescue medication was used (questions 3a, 4a, and 7a). Daily average scores were summarized each week for all participants with at least 4 non-missing records each week. Days with no reported rescue medication use were represented as 0 and included in the calculation with participants who reported yes and completed questions 3a, 4a and 7a. The baseline scores were calculated from Day -7 to Day -1. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. Here "n" signifies participants who were evaluable for this measure for the specified time point for each arm, respectively.

    End point description
    Severe annualized AER was assessed based on AER data up to Week 53. Annualized AER was assessed based on AER data up to Week 53. An asthma exacerbation defined as a progressive increase of asthma symptoms that does not resolve after the initiation of rescue medications and remains troublesome for the participant resulting in either 1) use of systemic corticosteroids or increase of a stable systemic maintenance dose for a duration of at least 3 consecutive days as prescribed or administered by the investigator; or 2) participant initiation of systemic corticosteroids for a duration of at least 3 consecutive days. An asthma exacerbation event was considered resolved 7 days after the last dose of oral corticosteroids is administered (10 days after an injectable corticosteroid). Courses of corticosteroids initiated after this time period were considered a separate new asthma exacerbation. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms.

    End point title
    		 Annual Asthma Exacerbation Rate (AER) by T-helper-2 (Th2) Status [34]
    End point description
    Annualized AER was assessed based on AER data up to Week 53. An asthma exacerbation defined as a progressive increase of asthma symptoms that does not resolve after the initiation of rescue medications and remains troublesome for the participant resulting in either 1) use of systemic corticosteroids or increase of a stable systemic maintenance dose for a duration of at least 3 consecutive days as prescribed; or 2) participant initiation of systemic corticosteroids for a duration of at least 3 consecutive days. AER was evaluated by subgroup Th2 status. Th2-high included those participants who had immunoglobulin E (IgE) >100 international unit per milliliter (IU/mL) and blood eosinophils >= 0.14 * 10 power 9 per Liter. Th2 low would include those participants who do not meet Th2 high status. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. Here "n" signifies evaluable participants for this measure for the specified time point for each arm, respectively.

    		 Annual Asthma Exacerbation Rate (AER) by Baseline FEV1% Predicted [46]
    End point description
    Annualized AER was assessed based on AER data up to Week 53. An asthma exacerbation defined as a progressive increase of asthma symptoms that does not resolve after the initiation of rescue medications and remains troublesome for the participant resulting in either 1) use of systemic corticosteroids or increase of a stable systemic maintenance dose for a duration of at least 3 consecutive days as prescribed; or 2) participant initiation of systemic corticosteroids for a duration of at least 3 consecutive days. It was considered resolved 7 days after the last dose of OCS administered (10 days after an injectable corticosteroid). Courses of corticosteroids initiated after this time period were considered a separate new asthma exacerbation. AER was evaluated by subgroup baseline FEV1% predicaed. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. Here "n" signifies evaluable participants for this measure for the specified time point for each arm, respectively.

    [46] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: This endpoint was reporting data for total number of participants of both the placebo reporting group, hence not reporting statistics for all the arms in the baseline period.

    		 Severe Asthma Exacerbation Rate (AER) by T-helper-2 (Th2) Status [62]
    End point description
    Severe AER was assessed based on AER data up to Week 53. An asthma exacerbation is a progressive increase of asthma symptoms that does not resolve after the initiation of rescue medications and remains troublesome for the participant resulting in either 1) use of systemic corticosteroids or increase of a stable systemic maintenance dose for a duration of at least 3 days as prescribed; or 2) participant initiation of systemic corticosteroids for a duration of at least 3 days. It was considered resolved 7 days after last dose of OCS (10 days after injectable corticosteroid). Corticosteroids initiated after this time period were considered separate new asthma exacerbation. Severe AER was evaluated by subgroup Th2 status. Th2-high include who had IgE >100 IU/mL and blood eosinophils >=0.14*10^9/L. Th2 low would include who do not meet Th2 high status. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. Here "n" signifies evaluable participants for this measure.

    [62] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: This endpoint was reporting data for total number of participants of both the placebo reporting group, hence not reporting statistics for all the arms in the baseline period.

    Secondary: Change from Baseline in Mean ACQ-6 Scores at Week 53 in Subgroups

    		 Close Top of page
    End point title
    		 Change from Baseline in Mean ACQ-6 Scores at Week 53 in Subgroups [71]
    End point description
    Asthma Control Questionnaire (ACQ) is a participant-reported questionnaire to assess the asthma control with 6 items assessing night-time waking, symptoms on waking, activity limitation, shortness of breath, wheeze, and rescue short-acting beta agonist use. Each item was rated on a 7-point Likert scale ranging from 0 (no impairment) to 6 (maximum impairment). Overall ACQ score was the mean of the 6 item scores with a score range of 0 (well controlled) to 6 (extremely poor controlled). Data collected on Day 1 prior to dosing was considered as baseline. Results were reported for overall ACQ score. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. The ITT population included all participants who were randomized into the study. Here "n" signifies participants who were evaluable for this measure for the specified time point for each arm, respectively.

    Notes
    [71] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: This endpoint was reporting data for total number of participants of both the placebo reporting group, hence not reporting statistics for all the arms in the baseline period.

    Secondary: Change from Baseline in Total AQLQ(S) Scores at Week 53 in Subgroups

    		 Close Top of page
    End point title
    		 Change from Baseline in Total AQLQ(S) Scores at Week 53 in Subgroups [72]
    End point description
    AQLQ: a 32-item questionnaire evaluating quality of life of participants with asthma including 4 domains (symptoms, activity limitations, emotional function, and environmental stimuli). Participants were asked to recall their experiences during the previous 2 weeks and to score each of the 32 questions on a 7-point scale ranging from 7 (no impairment) to 1 (severe impairment). The overall score was calculated as the mean response to all questions. The 4 domain scores were the means of the responses to the questions in each of the domains. Overall AQLQ score and 4 domain scores ranged from 7 (no impairment) to 1 (severe impairment). Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. The ITT population included all participants who were randomized into the study. Here "n" signifies participants who were evaluable for this measure for the specified time point for each arm, respectively.
    End point type
    Secondary
    End point timeframe
    Week 1 up to Week 53
    Notes
    [72] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: This endpoint was reporting data for total number of participants of both the placebo reporting group, hence not reporting statistics for all the arms in the baseline period.

    Secondary: Annual Asthma Exacerbation Rate (AER) by Atopic Asthma Status

    		 Close Top of page
    End point title
    		 Annual Asthma Exacerbation Rate (AER) by Atopic Asthma Status [73]
    End point description
    Annualized AER was assessed based on AER data up to Week 53. An asthma exacerbation defined as a progressive increase of asthma symptoms that does not resolve after the initiation of rescue medications and remains troublesome for the participant resulting in either 1) use of systemic corticosteroids or increase of a stable systemic maintenance dose for a duration of at least 3 consecutive days as prescribed; or 2) participant initiation of systemic corticosteroids for a duration of at least 3 consecutive days. AER was evaluated by subgroup Atopic and Non-atopic asthma status. Data were summarized together for ‘Placebo, Q2W’ and ‘Placebo, Q2/4W’ arms. The ITT population included all participants who were randomized into the study. Here "n" signifies participants who were evaluable for this measure for the specified time point for each arm, respectively.
    End point type
    Secondary
    End point timeframe
    Week 1 up to Week 53
    Notes
    [73] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: This endpoint was reporting data for total number of participants of both the placebo reporting group, hence not reporting statistics for all the arms in the baseline period.
