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   43839   clinical trials with a EudraCT protocol, of which   7280   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 evaluate the efficacy of 2 dose regimens of dupilumab compared to placebo, administered with concomitant topical corticosteroids (TCS), in adult patients with severe AD who are not adequately controlled with, or are intolerant to, oral CSA, or when this treatment is currently not medically advisable.
    E.2.2Secondary objectives of the trial
    To assess the safety and tolerability of 2 dose regimens of dupilumab compared to placebo, administered with concomitant TCS, in adult patients with severe AD who are not adequately controlled with, or are intolerant to, oral CSA, or when this treatment is currently not medically advisable.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Male or female, 18 years or older
    2. Severe, Chronic AD, (according to American Academy of Dermatology Consensus Criteria [Eichenfield 2014])
    3. EASI score ≥20 at the screening and baseline visits
    4. IGA score ≥3 (on the 0 to 4 IGA scale) at the screening and baseline visits
    5. ≥10% body surface area (BSA) of AD involvement at the screening and baseline visits
    6. Documented recent history (within 6 months before the screening visit) of inadequate response to treatment with TCS
    7. Have applied a stable dose of topical emollient (moisturizer) twice daily for at least the 7 consecutive days immediately before the baseline visit
    8. Documented history by a physician of either:
    A. No prior CSA exposure and not currently a candidate for CSA treatment due to:
    • medical contraindications (eg, uncontrolled hypertension on medication), or
    • use of prohibited concomitant medications (eg, statins, digoxin, macrolide
    • antibiotics, barbiturates, anti-seizure, nonsteroidal anti-inflammatory drugs,
    • diuretics, angiotensin-converting-enzyme inhibitors, St John’s Wort, etc), or
    • increased susceptibility to CSA-induced renal damage (elevated creatinine) and
    • liver damage (elevated function tests), or
    • increased risk of serious infections, or
    • hypersensitivity to CSA active substance or excipients,
    B. Previously exposed to CSA, and CSA treatment should not be continued or restarted due to:
    • intolerance and/or unacceptable toxicity (eg, elevated creatinine, elevated liver function tests, uncontrolled hypertension, paraesthesia, headache, nausea, hypertrichosis, etc), or
    • inadequate response to CSA (defined as flare of AD on CSA tapering after a maximum of 6 weeks of high dose [5 mg/kg/day] to maintenance dose [2 to 3 mg/kg/day] or a flare after a minimum of 3 months on maintenance dose). Flare is defined as increase in signs and/or symptoms leading to escalation of therapy, which can be an increase in dose, a switch to a higher-potency class of TCS, or the start of another systemic non-steroidal immunosuppressive drug. Or
    • requirement for CSA at doses >5 mg/kg/day, or duration beyond those specified in the prescribing information (>1 year).
    E.4Principal exclusion criteria
    1. Participation in a prior dupilumab clinical study
    2. Treatment with an investigational drug within 8 weeks or within 5 half-lives (if known), whichever is longer, before the screening visit
    3. Hypersensitivity and/or intolerance to corticosteroids or to any other ingredients contained in the TCS product used in the study

    5. Treatment with TCI within 1 week before the screening visit
    6. Treatment with biologics as follows:
    • Any cell-depleting agents including but not limited to rituximab: within 6 months before the screening visit, or until lymphocyte count returns to normal, whichever is longer
    • Other biologics: within 5 half-lives (if known) or 16 weeks prior to the screening visit, whichever is longer
    7. Regular use (more than 2 visits per week) of a tanning booth/parlor within 4 weeks of the screening visit
    8. Treatment with a live (attenuated) vaccine within 12 weeks before the screening
    9. Active chronic or acute infection requiring treatment with systemic antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 2 weeks before the screening

    10. Known or suspected history of immunosuppression, including history of invasive opportunistic infections (eg, tuberculosis [TB], histoplasmosis, Listeriosis, coccidioidomycosis, pneumocystosis, aspergillosis) despite infection resolution; or unusually frequent, recurrent, or prolonged infections, per investigator judgment
    11. Presence of any 1 of the following TB criteria:
    a. A positive tuberculin skin test at the screening visit
    b. A positive blood QuantiFERON®-TB or T-Spot test at the screening visit
    c. Chest x-ray (posterior-anterior and lateral views) at screening or within 3 months before the screening visit (radiology report must be available) with results consistent with prior TB infection (including but not limited to apical scarring, apical fibrosis, or multiple calcified granuloma).
