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 assess the efficacy of Trastuzumab deruxtecan (T-DXd) compared with investigator's choice chemotherapy in terms of PFS by BICR in the HR+, HER2-low (IHC 2+/ISH- and IHC 1+) populations
    Per valutare l'efficacia di Trastuzumab deruxtecan (T-DXd) rispetto alla chemioterapia scelta dallo sperimentatore in termini di PFS da BICR nelle popolazioni HR +, bassa espressione HER2- (IHC 2 + / ISH- e IHC 1+)
    E.2.2Secondary objectives of the trial
    OS in the HR+, HER2-low population
    • PFS by BICR and OS in the ITT population (HER2 IHC >0 <1+ and HER2-low)
    The other secondary objectives are:
    • PFS by Investigator assessment, ORR and DoR by BICR and Investigator assessment in the HR+, HER2-low population
    • ORR and DoR by BICR and Investigator assessment in the ITT population.
    • PFS2 according to Investigator assessment, time to first subsequent treatment or death (TFST) and time to second subsequent treatment or death (TSST) in the HR+, HER2-low population and the ITT population
    • the safety and tolerability profile of T-DXd compared with investigator's choice chemotherapy
    • the PK of T-DXd
    • symptoms, functioning and HRQoL in patients treated with T-DXd compared with investigator's choice single agent chemotherapy
    • the immunogenicity of T-DXd
    • OS nella popolazione HR+ e bassa espressività di HER2-
    • PFS da BICR e OS nella popolazione ITT (HER2 IHC> 0 <1+ e bassa espressione di HER2-)
    Gli altri obiettivi secondari sono:
    • PFS in base alla valutazione dello sperimentatore, ORR e DoR in base alla valutazione BICR e a quella dell’investigatore nella popolazione HR +, bassa espressione HER2-
    • ORR e DoR tramite valutazione BICR e dell’investigatore nella popolazione ITT.
    • PFS2 secondo la valutazione dello sperimentatore, tempo al primo trattamento successivo o decesso (TFST) e tempo al secondo trattamento successivo o decesso (TSST) nella popolazione HR +, con bassa espressione HER2- e popolazione ITT
    • il profilo di sicurezza e tollerabilità di T-DXd rispetto alla chemioterapia scelta dallo sperimentatore
    • il PK di T-DXd
    • sintomi, funzionamento e HRQoL nei pazienti trattati con T-DXd rispetto alla chemioterapia a singolo componente scelta dallo sperimentatore
    • l'immunogenicità di T-DXd
    E.2.3Trial contains a sub-study No
