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.

    General information about the trial
    Main objective of the trial
    To assess the effects of MEDI3506 compared with placebo on AD disease severity, in adult subjects with moderate-to-severe AD.
    Protection of trial subjects
    The study was performed in accordance with ethical principles that have their origin in the Declaration of Helsinki and are consistent with International Council for Harmonisation (ICH)/Good Clinical Practice (GCP), and applicable regulatory requirements. All participant must meet all inclusion criteria and not meet any exclusion criteria before receiving investigational product. IDMC was formed to monitor potential risk in the study.
    Background therapy
    		 Participants who meet the eligibility (inclusion/exclusion) criteria will discontinue use of topical corticosteroids and topical calcineurin inhibitorss at Visit 2. Subjects will be required to apply moisturizers twice daily for at least 7 days before randomization at Visit 3 (Day 1) with a minimum of 85% compliance
    Evidence for comparator

    Eczema Area and Severity Index (EASI) score
    Eczema Area and Severity Index (EASI) score is a composite score of area of involvement and severity score of 4 different body areas. The severity score is based on erythema, oedema/papulation, excoriation and lichenification of 4 body areas which are head, trunk, upper limbs and lower limbs. The score ranges between 0 to 72 points. Higher EASI score indicates more severe disease.

    		 Percent Change from Baseline to Week 16 in EASI score
    End point description
    The EASI evaluates 4 anatomic regions for severity and extent of key disease signs and focuses on the acute and chronic signs of inflammation (ie, erythema, edema, papulation, excoriation, and lichenification). The maximum score is 72, with higher values indicating more severe disease. Analysis was performed using mixed effect model for repeated measures and MCP-mod dose response model.

    The Patient-Oriented Eczema Measure (POEM) is a 7-item questionnaire for assessing disease symptoms including dryness, itching, flaking, cracking, sleep loss, bleeding, and weeping occurring in the past week. Each item is scored on a 5-point scale with 0 = no days, 1 = 1 to 2 days, 2 = 3 to 4 days, 3 = 5 to 6 days, and 4 = every day. The total POEM score is calculated by summing the score of each item resulting in a maximum of 28 and a minimum of 0, with higher values indicating severe disease
