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.

    E.5.2Secondary end point(s)
    • GCs tapering to a dose below 50 % of prednisolone (PDN) equivalent at the time of emapalumab start or to the same (or lower) dose being administered before the occurrence of MAS (in subjects already treated for the underlying condition) whichever occurs first at any time during the study.
    • GCs tapering to =1mg/kg/day of PDN equivalent at any time during the study.
    • Time to achieve GCs tapering as described above .
    • Time to first CR.
    • Proportion of subjects with overall response as defined by CR or PR (partial response).
    • Time to first overall response as defined by CR or PR.
    • MAS recurrence at any time after achievement of CR.
    • Withdrawal from the study due to lack of response as per Investigator decision.
    • Survival time.
    • Riduzione graduale della dose di GC al di sotto del 50% dell’equivalente di prednisolone (PDN) al momento dell’inizio di emapalumab o alla stessa dose (o dose inferiore) somministrata prima dell’insorgenza di MAS (nei soggetti già trattati per la condizione sottostante), a seconda di quale evento si verifichi per primo in qualsiasi momento durante lo studio.
    • Riduzione graduale della dose di GC a =1 mg/kg/giorno di equivalente di PDN in qualsiasi momento durante lo studio.
    • Tempo necessario per ottenere la riduzione graduale della dose di GC, come sopra definito.
    • Tempo alla prima CR.
    • Percentuale di soggetti con risposta complessiva definita in base alla CR o alla PR.
    • Tempo alla prima risposta complessiva definita in base alla CR o alla PR.
    • Recidiva di MAS in qualsiasi momento dopo il raggiungimento della CR.
    • Ritiro dallo studio a causa di mancanza di risposta in base alla decisione dello sperimentatore.
    • Tempo di sopravvivenza.
