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   43881   clinical trials with a EudraCT protocol, of which   7295   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. Il/La partecipante ha un'anamnesi di intolleranza alla venipuntura e/o difficile accesso alla venipuntura.
    8. ECG e risultati degli esami di laboratorio:
    a. Anomalia clinicamente significativa identificata alla valutazione medica o di laboratorio. Un/Una partecipante con un'anomalia clinica o parametri di laboratorio al di fuori dell'intervallo di riferimento può essere incluso/a solo se lo sperimentatore ritiene che il risultato non sia clinicamente significativo, che non introdurrà ulteriori fattori di rischio né interferirà con le procedure dello studio. I seguenti valori di laboratorio comportano l’esclusione alla visita di screening (valori anormali possono essere ripetuti una volta per la valutazione dell'idoneità durante il periodo di screening):
    i. Valore della creatinina sierica >1,5 volte il limite superiore dell'intervallo di riferimento.
    ii. Bilirubina totale sierica > 1,5 x ULN.
    iii. AST o ALT >2 x ULN.
    iv. HbA1c = 6,5%.
    v. Conta dei neutrofili = 1000/µL.
    vi. INR > 1,5x ULN.
    vii. PTT >1,5x ULN.
    b. Il partecipante non ha storia o evidenza di disfunzione d'organo o qualsiasi deviazione clinicamente significativa dalla norma all'esame obiettivo, segni vitali, elettrocardiogramma a 12 derivazioni (ECG) o determinazioni cliniche di laboratorio al di là di quanto coerente con la popolazione target.
    c. Il partecipante ha, alla visita di screening:
    i. Un intervallo PR >200 ms.
    ii. Presenza di un ritardo di conduzione interventricolare (IVCD) con intervallo QRS >120 msec.
    iii. Presenza di blocco di branca destra (RBBB) o blocco di branca sinistra (LBBB) con intervallo QRS >120 msec.
    iv. Un intervallo QTcF >450 ms (basato sulla correzione di Fridericia dove QTcF = QT/RR0,33).
    9. Ipersensibilità accertata o presunta (ad es. reazione anafilattica) a taldefgrobep alfa o ai costituenti della sua formulazione.
    10. Per le donne in età fertile, positività al beta-hCG sierico indicativa di gravidanza (e non falso positivo) allo screening o positività al test di gravidanza sulle urine al basale.
    11. Allattamento al seno.
    12. Detenuti o partecipanti detenuti contro la loro volontà.
    13. Partecipanti detenuti/e obbligatoriamente per il trattamento di una malattia psichiatrica o fisica (ad esempio, malattie infettive).
