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.

    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives

    Other types of substudies
    Specify title, date and version of each substudy with relative objectives: 1. Vaccination Response Sub-study :
    Sites will collect all available vaccination history from all study participants. Selected sites may collect additional blood samples for additional/optional/future vaccination research, such as:
    (1) measurement of historical protective antibody titers in serum;
    (2) humoral (serum) and/or cellular (peripheral blood mononuclear cells [PBMCs]) responses to vaccinations received during the study. These samples will only be collected from participants who have provided
    additional consent for the procedure. Such samples will be collected at the visits identified in the SoA.
    Data obtained from this substudy will not be part of the clinical database; instead, they may be described in a separate report.
    2. Imaging Substudy:
    A photography substudy will be performed at selected study sites. In this substudy, site staff will take photographs of bullous lesions located at various anatomical regions of participants per the discretion of the
    investigator. As a guidance, timepoints of baseline, CDA, CR, and relapse are indicated; however, photographs may also be taken at intermediate timepoints.
    Photography is generally accepted as a routine practice for documenting dermatological conditions in medicine. Participants will be requested to provide consent for any use that will be made of the image and for
    sharing anonymized pictures with the sponsor.

    Altre tipologie di sottostudi
    specificare il titolo, la data e la versione di ogni sottostudio con i relativi obiettivi: 1. Sottostudio sulla risposta alla vaccinazione:
    I centri raccoglieranno tutta la storia vaccinale disponibile da tutti i partecipanti allo studio. I centri selezionati possono raccogliere campioni di sangue aggiuntivi per ricerche aggiuntive/facoltative/future sulla vaccinazione, come ad esempio:
    (1) misurazione dei titoli anticorpali protettivi storici nel siero;
    (2) risposte umorali (siero) e/o cellulari (cellule mononucleate del sangue periferico [PBMC]) alle vaccinazioni ricevute durante lo studio. Questi campioni saranno raccolti solo dai partecipanti che hanno fornito
    ulteriore consenso alla procedura. Tali campioni saranno raccolti in occasione delle visite individuate nella SoA.
    I dati ottenuti da questo sottostudio non faranno parte del database clinico; possono invece essere descritti in una relazione separata.
    2. Sottostudio di imaging:
    Un sottostudio di fotografia sarà svolto in centri di studio selezionati. In questo sottostudio, il personale del centro scatterà fotografie di lesioni bollose localizzate in varie regioni anatomiche dei partecipanti a discrezione del
    medico di studio. A titolo indicativo, sono indicati i punti temporali del baseline, CDA, CR e ricaduta; tuttavia, le fotografie possono essere scattate anche in punti temporali intermedi.
    La fotografia è generalmente accettata come pratica di routine per documentare le condizioni dermatologiche in medicina. Ai partecipanti sarà richiesto di fornire il consenso per qualsiasi uso che verrà fatto dell'immagine e per
    condivisione di immagini anonime con lo sponsor.

    Participants who reach the EoTP visit (week 36) may be offered the option to roll over into a long-term, OLE study (ARGX-113-2010).

    Participants who are eligible but choose not to roll over into the OLE study ARGX-113-2010 will complete a 7-week treatment-free follow-up period.

    If a participant permanently withdraws from the study or is permanently withdrawn from the study by the investigator, standard-of-care BP treatment may be administered by the participant’s primary care physician.
    Ai paz che raggiungono la visita EoTP (settim 36) può essere offerta la possibilità di passare a uno studio OLE a lungo termine (ARGX-113-2010).

    I paz che sono idonei ma scelgono di non passare allo studio OLE ARGX-113-2010 completeranno un periodo di follow-up di 7 settimane senza trattamento.

    Se un paz si ritira definitivamente dallo studio o viene definitivamente ritirato dallo studio dallo sperimentatore, il trattamento standard della PA può essere somministrato dal medico di base del paz.
