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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

The total EASI score ranges from 0 (minimum) to 72 (maximum) points, with the higher scores reflecting the worse severity of AD. Percent change from baseline in EASI score at Week 16 based on observed values set to missing after rescue treatment was reported. Values after first rescue treatment were set to missing and subjects with missing EASI score at Week 16 were counted as non-responders. FAS included all randomized subjects and was based on the treatment allocated (as randomized). Here, “Number of Subjects Analysed” signifies those subjects who were evaluable for this endpoint.

    The EASI score was used to measure the severity and extent of AD and measures erythema, infiltration, excoriation and lichenification on 4 anatomic regions of the body: head, trunk, upper and lower extremities. The total EASI score ranges from 0 (minimum) to 72 (maximum) points, with the higher scores reflecting the worse severity of AD. Percentage of subjects who achieved EASI-50 (≥50% Improvement from baseline) at Week 16 were reported. Values after first rescue treatment were set to missing and subjects with missing EASI score at Week 16 were counted as non-responders. FAS included all randomized subjects and was based on the treatment allocated (as randomized). Here, “Number of Subjects Analysed” signifies those subjects who were evaluable for this endpoint.

    		 Percentage of Subjects With Improvement in Weekly Average of Daily Peak Pruritus NRS Score ≥4 Based on All Observed Values Regardless of Rescue Treatment at Week 16
    End point description
    Pruritus NRS was an assessment tool used to report the intensity of a subject’s pruritus (itch), both maximum and average intensity, using an electronic questionnaire (e-diary). Subjects were asked the following question: how would you rate your itch at the worst moment during the previous 24 hours (for maximum itch intensity on a scale of 0 - 10 [0 = no itch; 10 = worst itch imaginable]). Percentage of subjects with improvement of weekly average of daily peak pruritus NRS score ≥4 from baseline to Week 16 based on all observed values regardless of rescue treatment were reported. FAS included all randomized subjects and was based on the treatment allocated (as randomized). Here, “Number of Subjects Analysed” signifies those subjects who were evaluable for this endpoint.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    26 Sep 2018
    - Modified exclusion criterion #4 to decrease the length of the washout period from 12 weeks to 4 weeks before the baseline visit for immunosuppressive/immunomodulating drugs (eg, systemic corticosteroids, cyclosporine, mycophenolate-mofetil, interferon-gamma [IFN-gamma], Janus kinase inhibitors, azathioprine, methotrexate, etc) and phototherapy. These washout changes were consistent with the prior dupilumab adult atopic dermatitis phase 3 studies (eg, R668-AD-1224) and acceptable for subjects enrolled in this study - Updated exclusion criterion #11 to be consistent with prior dupilumab adult atopic dermatitis phase 3 studies (eg, R668-AD-1224). Active chronic or acute infection requiring systemic treatment with antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 2 weeks (was previously 8 weeks before the screening visit) before the baseline visit, or superficial skin infections within 1 week (was previously 4 weeks before the screening visit) before the baseline visit
    29 Nov 2018
    - Added text in Exclusion Criterion #12 to specify that subjects with a positive tuberculosis (TB) QuantiFERON test result will be excluded from the study - Exclusion Criterion # 20: Added myocardial infarction, unstable arterial hypertension, unstable angina, and cerebrovascular accident as examples of uncontrolled cerebrocardiovascular conditions that will exclude a subject from the study - Exclusion Criterion #25: Added clarification that the reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient, based on Clinical Trial Facilitation Group guideline on contraception
    03 Jan 2019
    - Added secondary safety and pharmacokinetic (PK) endpoints
