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   44335   clinical trials with a EudraCT protocol, of which   7366   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.

    3. During the last 7 days prior to Day 1, for the treatment of AD, the subject must have used only non-medicated topical therapy (ie, emollient) at least twice daily, without other active ingredients indicated to treat AD, or other additives which could affect AD (eg, hyaluronic acid, urea, ceramide or filaggrin degradation products), with response to treatment remaining inadequate at baseline. The participant must also be willing and able to comply with standardized background topical therapy, as per protocol guidelines, throughout the remainder of the
    study.
    4. Must agree to avoid prolonged exposure to the sun and not to use tanning booths, sun lamps or other ultraviolet light sources during the study.
    5. If receiving concomitant medications for any reason other than AD, must be on a stable regimen, which is defined as not starting a new drug or changing dosage within 7 days or 5 half lives (whichever is longer) prior to Day 1 and through the duration of the study.
    6. Body weight >=40 kg. The body weight threshold may be revised after interim PK data from adolescents in study B7451012 have been evaluated by the E DMC. Study sites will be notified of the revised body weight threshold, if applicable.
    7. Male or Female
    Contraception use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
    a. Male participants: No contraceptive measures required.

    • Is not a woman of childbearing potential (WOCBP)
    OR
    • Is a WOCBP (all female participants, regardless of whether or not they have experienced/reported menarche, are considered WOCBP unless they are permanently sterile or confirmed infertile). A WOCBP who is sexually active must use a contraceptive method that is highly effective, with a failure rate of <1%, as described in Appendix 4 during the intervention period and for at least 28 days after the last dose of study intervention. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention.

    • Storia recente documentata (entro 6 mesi prima della visita di screening) di risposta inadeguata al trattamento con terapia topica medicata per DA per almeno 4 settimane o che ha richiesto terapie sistemiche per il controllo della malattia.
    NOTA: La terapia topica medicata è definita come un prodotto topico che contiene un principio attivo farmaceutico indicato per il trattamento della DA (indipendentemente dal fatto che si tratti di un prodotto da banco [OTC] o di un prodotto con prescrizione).
    • DA da moderata a severa (BSA interessata >= 10%, IGA >= 3, EASI >=16, punteggio secondo la scala NRS per il prurito >= 4 alla visita al basale).
    3. Durante gli ultimi 7 giorni prima del Giorno 1, per il trattamento della DA, il soggetto deve aver utilizzato solo terapie topiche non medicate (cioè emollienti) almeno due volte al giorno, senza altri principi attivi indicati per il trattamento della DA, o altri additivi che potrebbero influenzare la DA (ad esempio, acido ialuronico, urea, ceramide o prodotti di degradazione della filaggrina), con una risposta al trattamento che rimane inadeguata al basale. Il partecipante deve anche essere disposto e in grado di rispettare la terapia topica di base standardizzata, in base alle linee guida del protocollo, per tutto il rimanente periodo di studio.
    4. Deve accettare di evitare l'esposizione prolungata al sole e di non utilizzare cabine abbronzanti, lampade solari o altre fonti di luce ultravioletta durante lo studio.

    • Non è una donna potenzialmente fertile (WOCBP)
    OPPURE
    • È una WOCBP (tutte le partecipanti di sesso femminile, indipendentemente dal fatto che abbiano sperimentato/riferito o meno il menarca, sono considerate
    WOCBP a meno che non siano permanentemente sterili o confermate sterili).
    • Una WOCBP sessualmente attiva deve utilizzare un metodo contraccettivo altamente efficace, con una percentuale di insuccesso dell'<1%, come descritto nell'Appendice 4 durante il periodo di intervento e per almeno 28 giorni dopo l'ultima dose di intervento di studio.
