Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   43216   clinical trials with a EudraCT protocol, of which   7153   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.5 End points
    E.5.1Primary end point(s)
    The efficacy will be evaluated through the proportion of patients in complete clinical remission (CCR) at 3 months without any relapse during the study period. The CCR will be defined as the absence of new bullous and skin inflammatory lesions and absence of pruritus (VAS for pruritus <3) for at least 2 weeks. The patient will report daily on his leaflet the presence of lesions so that, at the next study visit, the investigator will determine precisely the date of CCR.
    E.5.1.1Timepoint(s) of evaluation of this end point
    3 months
    E.5.2Secondary end point(s)
    1. The delay to achieve CCR (first CCR occurrence during study period) will be defined as the time, in days, between the date of the baseline visit and the date of CCR.as it is defined above. Follow-up will be censored at 3 months for patients not achieving CCR or at the date of last visit completed for the lost to follow-up.
    2. ICR is defined as the absence of new bullous and skin inflammatory lesions and absence of pruritus (VAS for pruritus <3) for at least 4 consecutive days. This delay will be defined as the time, in days, between the date of the baseline visit and the date of ICR. Follow-up will be censored at W3 for patients not achieving ICR or at the date of last visit completed for the lost to follow-up.
    3. The initial failure of treatment will be defined as the absence of ICR (see endpoint 2) at W3.
    4. The impact of treatment on relapses will be studied using the incidence rate of the relapses and the rate of patients presenting with at least one relapse over the study period. Relapse will be defined as the reappearance, in a patient who previously achieved CCR, of skin inflammatory and/or bullous lesions and/or pruritus (pruritus >2/10 on the VAS and at least 3 bullous or inflammatory lesions/d for at least 3 consecutive days).
    5. The delay to the relapse will be defined, in people previously achieving CCR, as the time, in days, between the date of the CCR and the date of the relapse as reported by the patient. Follow-up will be censored at 3 months for patients not having a relapse or at the date of last visit completed for the lost to follow-up.
    6. The QoL will be evaluated using the DLQI score. The Dermatology life Quality Index (DLQI) is a simple ten-question auto questionnaire used to measure the impact of skin disease on the quality of life of an affected person. It is designed for people aged 16 years and above. DLQI score 13 (Annex 1) is validated in the frame of dermatological clinical research. A French version is validated14.
    The QoL evolution will be assessed successively between baseline and (W4, W8 and W12).
    7. A visual analogical scale (VAS) will be used for pruritus self-assessment. The patient will use a VAS calibrated from 0 to 100 mm, not hatched, marked at each end, on one side "no pruritus at all" and on the other side "most intense pruritus" and he will be asked to grade his level of pruritus during the past 7 days. The pruritus evolution will be assessed successively between baseline and (W4, W8 and W12).
    8. The consumption of topical steroids will be evaluated by the quantity, in grams, of drugs used over the study period. At W4, W8 and W12 the patients will bring back all their tubes which will be weighted, and the quantity used reported.
    9. All the adverse events (clinical and biological) occurring over the study period will be collected with their type, grade and severity. At each visit the investigator will record all the events since the last visit and check for any biological trouble on the systematic blood analyses
