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.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate the efficacy of 48-week study intervention with JNJ- 3989+JNJ-6379+NA regimen compared to NA alone.
    Valutare l’efficacia di un trattamento di 48 settimane con un regime JNJ-3989+JNJ-6379+AN rispetto a AN in monoterapia.
    E.2.2Secondary objectives of the trial
    1. To evaluate the safety and tolerability of the study intervention throughout the study.
    2. To evaluate the efficacy of the study intervention at the end of treatment.
    3. To evaluate the efficacy as measured by blood markers (such as HBsAg, HBV DNA, and ALT) during study intervention and follow-up.
    4. To evaluate the frequency of virologic breakthrough during study intervention.
    5. To evaluate the proportion of participants requiring NA re-treatment during follow-up.
    6. To identify baseline and on-treatment markers associated with sustained off-treatment response.
    7. To evaluate the PK of JNJ 3989 (JNJ-3976 and JNJ-3924), JNJ-6379, and NA, as applicable.
    1.Valutare la sicurezza e la tollerabilità del trattamento dello studio nel corso dello studio.
    2.Valutare l’efficacia del trattamento dello studio al termine del trattamento.
    3.Valutare l’efficacia misurata dai marcatori ematici (quali ad esempio HBsAg, DNA HBV e alanina aminotransferasi [ALT]) durante il trattamento dello studio e la fase di follow-up.
    4.Valutare la frequenza del breakthrough virologico duranteil trattamento dello studio.
    5.Valutare la percentuale di partecipanti che necessitano il ritrattamento con AN durante il follow-up.
    6.Identificare i marcatori al basale e a trattamento in corso, associati con una risposta duratura a trattamento non in corso.
    7.Valutare la farmacocinetica (PK) di JNJ-3989, (JNJ-3976 e JNJ-3924), JNJ-6379, e AN, se pertinente.
