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   44339   clinical trials with a EudraCT protocol, of which   7369   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 ).

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: Not all randomized subjects were treated with study drugs. Hence, the worldwide number enrolled in the trial, which is the same as the number randomized, differs from the number of subjects reported in the baseline period.

    End point title
    		 Annual Asthma Exacerbation Rate (AER) for Eosinophilic Phenotype (EOS+) Participants [1]
    End point description
    The annual asthma exacerbation rate (AER) was calculated as the total number of observed exacerbations in each group up to week 52, divided by total duration of person-year follow-up in each group. An asthma exacerbation is 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 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 as outlined in the Asthma Action Plan provided to the participant by the investigator on Day 1. The modified intent-to-treat (mITT) population included all randomized participants who received any dose of investigational product.

    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. ACQ-6 score was summarized together for all participants. The mITT population included all randomized participants who received any dose of investigational product.

    Participants were provided inhalers of the same dose (medium- or high-dose) inhaled corticosteroid (ICS) plus long-acting beta antagonist (LABA) combination product as baseline prophylactic medication and continued with same dose throughout the study. Rescue medications such as short-term beta2 agonists were used as first-line treatment for worsening asthma symptoms. Investigator prescribed additional short term asthma controller medications included additional ICS, theophylline, inhaled cromones or antimuscarinics; if asthma symptoms remained mild but not resolved. If asthma symptoms worsened, received an oral corticosteroid burst. All rescue medications use with prophylactic medication (+ prophylactic) and without prophylactic medication (- prophylactic) was recorded in asthma symptom dairy and analyzed on a bi-weekly basis and compared to baseline scores.

    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) and mean response was calculated as overall score. 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). The AQLQ(S) responses were categorized as improvement (defined as change from baseline >=0.5), no change (defined as change from baseline >= -0.5 to < 0.5), and worse (defined as change from baseline < -0.5). 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
    Baseline up to Week 51-52
    Notes
    [28] - 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: The EOS- participants were only for exploratory analyses, and hence, data was reported for EOS+ participants in this endpoint.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    11 Apr 2011
    The exclusion criteria for mitigation of parasitic infection associated with eosinophil depletion due to benralizumab were modified. Added an exploratory objective to analyse the performance of different helminth serology assays. Exclusion criterion 1 was revised to exclude subjects with allergic bronchopulmonary aspergillosis from participation. Exclusion criterion 27 was revised to ensure subjects were able to perform spirometry during the study. Exclusion criterion 28 was added to exclude subjects who used any oral or ophthalmic β-adrenergic antagonist. Withdrawal criterion was added that a subject would be discontinued from further investigational product administration based on an AE as determined by the sponsor. Withdrawal criterion added that the development of S stercoralis in subjects with chronic OCS-dependent asthma. Schedule of study procedures: The hepatitis A antibody test was removed from screening. Added that unblinded staff must not administer investigational product to the subject to maintain the integrity of the study blind. Added Asthma Symptom Diary Anchoring Questions. Schedule of study procedures: Hepatitis A antibody test was removed from screening. Schedule of study procedures: An early discontinuation visit was added and added serology testing for S stercoralis in subjects with chronic oral corticosteroiddependent asthma at Weeks 16, 32, 52, and 66. Added 4-day window to Screening Visit. Added collection of time of administration of the first injection of investigational product. Added Early Discontinuation Visit for subjects who discontinued the study prematurely. Added footnote under list of serum chemistries to conduct and assess tests for AST, ALT, ALP, and total bilirubin concurrently. Added procedures for parasite serology testing of S stercoralis, and for collection and analysis of stool samples. Added section on hepatic function abnormality as a measure of safety. Changed interim analysis to primary analysis.
    14 Nov 2011
    Changed total number of subjects to be randomized to 522 and total number of EOS+ subjects to be randomized to 280; changed number of EOS+ subjects in each treatment regimen from 60 to 70. Changed number of months for expected enrollment to 15-18. Changed number of weeks that subjects should return to the study site for peripheral blood eosinophil counts to 8. Changed study-stopping reason to reflect the occurrence of confirmed immune complex disease in a subject treated with benralizumab. Changes in inclusion and exclusion criteria. Added that a major deviation from the study protocol as judged by the investigator and/or the sponsor a reason for withdrawal. Modified procedures for following subjects for safety who were permanently discontinued from receiving investigational product. Changed procedures to allow for replacement of subjects who had not met major eligibility criteria and were withdrawn after receiving at least one dose of investigational product in error. Specified 21-gauge needle to be used. Specified when investigational product should not be administered. Updated text describing medium and high doses of ICS/LABA combination inhalers; added that subjects on high-dose ICS/LABA who used a secondary ICS inhaler were to be classified as high-dose subjects. Text describing rescreening procedures was modified. Removed sentence and reference citation regarding minimally clinical important difference in the TNSS-3. Changed the significance level to 0.2; changed the two-sided confidence interval to 80%; changed the sample size of the eosinophil-positive cohort and provided justification to augment the probability that the primary objective of detecting a reduction in asthma exacerbations in active versus placebo with adequate statistical power will be achieved; updated references as needed.
    16 Jul 2012
    Added section describing potential reason for stopping study for futility. Added interim analysis and a section describing unblinding for the interim analysis. Changed references to Week 52 analysis to Stage I analysis; Clarified the Stage I and Stage II analyses that will be conducted. Changed the primary endpoint analysis from Cochran-Mantel-Haenszel method to Poisson regression with overdispersion adjustment factor. Cochran-Mantel- Haenszel and negative binomial regression were considered sensitivity analyses. Removed weighted mean rate of asthma exacerbations as an exploratory endpoint.
