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 End points
    E.5.1Primary end point(s)
    The primary endpoint for safety is the incidence of AEs (overall or
    grouped as neurological, psychiatric or cardiovascular).
    The hypothesis for the primary endpoint for safety is that ABvac40 will
    be safe for human administration, according to the observed pattern of
    AEs. The trial will be considered satisfactory if the pattern of AEs (overall
    or grouped as neurological, psychiatric or cardiovascular) is consistent
    with a good safety and tolerability profile of ABvac40 for human
    administration at the final visit.
    The primary efficacy endpoint is the average maximal increment (M¿) of
    anti-Aß40 antibody signal (OD in ELISA).
    The hypothesis for the primary efficacy endpoint is that ABvac40 will
    elicit immune responses to Aß40 (statistical superiority compared to
    placebo). The trial will be considered successfully confirmatory
    regarding efficacy (immunogenicity) of ABvac40 if the average maximal
    increment (M¿) of anti-Aß40 antibody signal (OD in ELISA) in the verum
    group is = 1.778 OD than the average M¿ in the placebo group (the
    difference reached between both groups in the phase I clinical trial of
    ABvac40) at the final of the study
    Analisi primaria di sicurezza:
    La variabile primaria di sicurezza è la frequenza (%) degli eventi avversi nel corso dello studio. L’endpoint primario di sicurezza verrà analizzato in modo descrittivo nella popolazione di sicurezza.
    L'ipotesi per l’endpoint primario di sicurezza presuppone che la somministrazione di ABvac40 sia sicura nell’uomo in base al pattern di AE osservato.
    La sperimentazione sarà considerata soddisfacente se, alla fine dello studio, il pattern degli AE rilevati (a livello generale o raggruppati come eventi neurologici, psichiatrici e cardiovascolari), permetterà di definire un buon profilo di sicurezza e di tollerabilità per la somministrazione di ABvac40 nell'uomo.
    Ai fini dell’analisi primaria di sicurezza verranno raggruppati tutti i soggetti negativi e positivi alla PET-amiloide.
    Analisi primaria di efficacia (immunogenicità):
    La variabile primaria di efficacia corrisponde all’incremento massimo del segnale specifico di anticorpi anti-Aß40 (OD) in ciascun soggetto rispetto alla visita di pre-trattamento (V0 o V1). Ai fini dell’analisi primaria di efficacia verranno raggruppati tutti i soggetti negativi e positivi alla PET-amiloide.
    Per quanto concerne l’efficacia primaria (attività biologica), la sperimentazione si considererà soddisfacente se l’incremento massimo medio del segnale specifico di anticorpi anti-Aß40 nel gruppo di trattamento raggiunge lo stesso incremento rilevato nello studio clinico di fase I su ABvac40 (=1,778 OD in titolazione ELISA) rispetto al gruppo trattato con placebo.
