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   43861   clinical trials with a EudraCT protocol, of which   7284   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.

    7. Permanenza in ospedale o in strutture che danno cure continue e che implicano una dipendenza media o alta (è invece permessa la residenza in strutture che danno leggera assistenza, nelle quali l'autonomia è sufficiente da consentire una valida valutazione delle attività quotidiane).

Inoltre dovranno essere esclusi i soggetti affetti da una delle seguenti anomalie:
    • Clearance della creatinina < 30 mL/min allo Screening, valutato dal laboratorio centrale secondo equazione di Cockcroft-Gault

Malattia immunologica, epatica o endocrina (non adeguatamente trattata) concorrente acuta o cronica clinicamente significativa (secondo il parere del ricercatore), e/o altre malattie instabili o importanti diverse dal morbo di Alzheimer. Devono essere esclusi i soggetti con cirrosi biliare primitiva
    16. Diagnosi di cancro nei 2 anni precedenti alla Baseline (salvo carcinoma della pelle a cellule squamose o basocellulare o tumore della prostata Stadio 1) tranne in caso di completa guarigione della malattia da almeno 2 anni

    •Carbamazepina, primidone
    •Farmaci associati alla metaemoglobinemia, p. es. dapsone, anestetici locali come benzocaina usati in modo cronico, primachina e antimalarici analoghi, sulfonamidi
    19. Attuale o Precedente partecipazione alle seguenti sperimentazioni cliniche:
    •Sperimentazione clinica di fase 3 di un prodotto per disturbi cognitivi nei 3 mesi che precedono lo Screening (tranne in caso di randomizzazione confermata nel gruppo placebo)
    •Sperimentazione clinica di un farmaco o dispositivo terapeutico o biologico o alimento medicinale in cui l'ultima dose/somministrazione è avvenuta meno di 28 giorni prima della Baseline
