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   43871   clinical trials with a EudraCT protocol, of which   7290   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.3Principal inclusion criteria
    Each subject eligible to participate in this study must meet all the following criteria:
    1. Aged 1 to < 4 years at randomization.
    2. Written informed consent from the legal guardian/parent (or both parents where required by local authorities). Provide assent where required and as appropriate per local requirements.
    3. Documented history of physician-diagnosed IgE-mediated peanut allergy that includes the onset of characteristic signs and symptoms of allergy within 2 hours of known oral exposure to peanut or peanut-containing food. In general, characteristic signs and symptoms of IgE-mediated allergic reactions are objective and affect the target organs of skin, GI tract, upper/lower respiratory tract, cardiovascular system, or a combination of target organs as follows:
    System: Examples of Symptoms (Sampson, 2014)
    Cutaneous: Pruritus, erythema/flushing, urticaria, angioedema, contact urticaria
    Ocular: Pruritus, tearing, conjunctival injection, periorbital edema
    Upper respiratory tract: Pruritus, nasal congestion, rhinorrhea, sneezing, hoarseness, laryngeal edema
    Lower respiratory tract: Cough, wheezing, dyspnea, chest tightness/pain
    Gastrointestinal: Oral pruritus, oral angioedema (lips, tongue, or palate), colicky abdominal pain, nausea, emesis, diarrhea
    Cardiovascular: Tachycardia, dizziness, hypotension, loss of consciousness/ fainting
    4. Mean wheal diameter on skin prick test (SPT) to peanut of at least 3 mm greater than the negative control (diluent) or serum IgE to peanut ≥ 0.35 kUA/L, obtained within 12 months before randomization.
    5. Development of age-appropriate dose-limiting allergy symptoms after consuming single doses of peanut protein > 3 mg to ≤ 100 mg in a screening DBPCFC.
    6. A palatable vehicle food to which the subject is not allergic must be available for administering study product.
    Chaque sujet éligible à participer à cette étude doit répondre à tous les critères suivants :
    1. Être âgé(e) de 1 à < 4 ans au moment de la randomisation.
    2. Consentement éclairé écrit du tuteur légal/parent (ou des deux parents si les autorités locales l’exigent). Donner son assentiment si nécessaire et, le cas échéant, conformément aux exigences locales.
    3. Antécédents documentés d’allergie aux arachides à médiation IgE diagnostiquée par un médecin, incluant l’apparition de signes et symptômes caractéristiques d’allergie dans les 2 heures suivant une exposition orale connue à des arachides ou à des aliments contenant des arachides. En général, les signes et symptômes caractéristiques des réactions allergiques à médiation IgE sont objectifs et affectent les organes cibles de la peau, du tractus gastro-intestinal, des voies respiratoires supérieures/inférieures, du système cardiovasculaire ou une combinaison d’organes cibles comme suit :
    Système: Exemples de symptômes (Sampson, 2014)
    Cutané: Prurit, érythème/bouffées vasomotrices, urticaire, angio-œdème, urticaire de contact
    Oculaire: Prurit, déchirure, injection conjonctivale, œdème périorbitaire
    Voies respiratoires supérieures: Prurit, congestion nasale, rhinorrhée, éternuements, enrouement, œdème laryngé
    Voies respiratoires inférieures: Toux, respiration sifflante, dyspnée, serrement de poitrine/douleur thoracique
    Système gastro-intestinal: Prurit buccal, angio-œdème buccal (lèvres, langue ou palais), douleurs abdominales coliqueuses, nausées, vomissements, diarrhée
    Cardiovasculaire: Tachycardie, vertiges, hypotension, perte de connaissance/ évanouissement

    4. Diamètre moyen de la papule lors du prick-test (SPT) à l’arachide d’au moins 3 mm supérieur à celui du témoin négatif (diluant) ou du sérum IgE à l’arachide ≥ 0,35 kUA/l, obtenu dans les 12 mois précédant la randomisation.
    5. Développement de symptômes d’allergie limitant la dose en fonction de l’âge après avoir consommé des doses uniques de protéine d’arachide > 3 mg à ≤ 100 mg dans une DBPCFC de sélection.
    6. Un aliment véhicule appétissant auquel le sujet n’est pas allergique doit être disponible pour administrer le produit à l’étude.
    E.4Principal exclusion criteria
    Each subject eligible to participate in this study must NOT meet any of the following exclusion criteria:
    1. History of severe or life-threatening anaphylaxis.
    2. History of hemodynamically significant cardiovascular or renovascular disease, including uncontrolled or inadequately controlled hypertension.
    3. History of EoE; other eosinophilic GI disease; chronic, recurrent, or severe gastroesophageal reflux disease (GERD); or symptoms of dysphagia (eg, difficulty swallowing, food “getting stuck”).

    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is the proportion of subjects treated with AR101 compared with placebo who tolerate an at least 600 mg single dose of peanut protein with no more than mild allergy symptoms during the exit DBPCFC, assessed using the Fisher exact test. Desensitization response rates and associated 95% CIs will be presented for each treatment group using exact Clopper-Pearson CIs.
    Le critère principal d’évaluation de l’efficacité est la proportion de sujets traités par AR101, par rapport à ceux traités par placebo, qui tolèrent une dose unique de protéines d’arachide d’au moins 600 mg sans symptômes autres que de légers symptômes d’allergie lors de la DBPCFC de sortie, évaluée à l’aide du test d’exactitude de Fisher. Les taux de réponse de désensibilisation et les intervalles de confiance (IC) à 95 % associés seront présentés pour chaque groupe de traitement à l’aide des IC exacts de Clopper-Pearson.
