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   44338   clinical trials with a EudraCT protocol, of which   7368   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To compare the efficacy of the SQ tree SLIT-tablet to placebo in the treatment of moderate to severe allergic rhinitis and/or conjunctivitis induced by pollen from birch and trees belonging to the birch homologous group in children and adolescents (5 through 17 years of age) based on the average allergic rhinoconjunctivitis daily total combined score (average TCS) during the birch pollen season (BPS)
    E.2.2Secondary objectives of the trial
    Key secondary objectives:
    To compare the efficacy of the SQ tree SLIT-tablet to placebo based on:
    •The average TCS during the tree pollen season (TPS)
    •The average allergic rhinoconjunctivitis daily symptom score (average DSS) during the BPS and TPS
    •The average allergic rhinoconjunctivitis daily medication score (average DMS) during the BPS and TPS
    Secondary objectives:
    •To compare the safety and tolerability of the SQ tree SLIT-tablet to placebo
    •To compare the efficacy of the SQ tree SLIT-tablet to placebo using additional endpoints based on daily allergic rhinoconjunctivitis symptoms and rescue medication use
    •To compare the efficacy of the SQ tree SLIT-tablet to placebo based on assessments of quality of life
    •To compare the efficacy of the SQ tree SLIT-tablet to placebo based on patient treatment satisfaction
    •To compare the effect of the SQ tree SLIT-tablet to placebo on immunological parameters to birch, alder, hazel and oak pollen
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Subjects are eligible to be included in the trial only if all the following criteria apply:
    •Male or female of any race/ethnicity aged ≥4 to <18 years on the day informed consent is obtained from the parent/caregiver; the subject must be ≥5 to <18 years old at the randomisation visit
    •A documented, physician diagnosed, clinically relevant history of moderate to severe AR/C induced by birch pollen (with or without asthma) despite having received treatment with symptom-relieving medication during at least 1 previous tree pollen season for ages 4 through 6 years at screening or at least 2 previous tree pollen seasons for ages 7 through 17 years at screening
    •Positive skin prick test (SPT) to Betula verrucosa at screening
    •Positive specific IgE to Bet v at screening
    •Presence of 1 or more of the following Allergic Rhinitis Impact on Asthma (ARIA) quality of life items due to AR/C during the previous BPS:
    a.Sleep disturbance
    b.Impairment of daily activities, leisure and/or sport
    c.Impairment of school or work
    d.Troublesome symptoms
    E.4Principal exclusion criteria
    Subjects are excluded from the trial if any of the following criteria apply:
    •A clinically relevant history of symptomatic seasonal AR/C caused by an allergen source, other than tree pollen from the birch homologous group, with a season overlapping the TPS
    •A clinically relevant history of symptomatic perennial AR/C caused by an allergen source such as animal hair and dander to which the subject is exposed during the TPS
    •Any clinical deterioration of asthma (i.e. asthma exacerbation) that resulted in emergency treatment, hospitalisation or treatment with systemic corticosteroids within 3 months prior to randomisation
    •Reduced lung function at randomisation defined as forced expiratory volume in 1 second (FEV1) <70% of predicted value. For subjects with asthma, this is assessed on subject’s usual asthma medication following at least a 6-hour wash-out of SABA. This criterion does not need to be fulfilled if the subject is <7 years old, cannot perform reproducible FEV1 manoeuvres despite coaching and is not considered as having a diagnosis of asthma
    •Ongoing treatment with any allergy immunotherapy product
    •Severe chronic oral inflammation
    •A diagnosis of eosinophilic oesophagitis
    •A relevant history of systemic allergic reaction e.g. anaphylaxis with cardiorespiratory symptoms, generalised urticaria or severe facial angioedema that in the opinion of the investigator may constitute an increased safety concern
    •Immunosuppressive treatment (ATC code L04 or L01) within 3 months prior to the screening visit
