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   43845   clinical trials with a EudraCT protocol, of which   7282   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
    The primary objective ofthis study is to evaluate the safety and feasibility of iC9-GD2-CAR T cells infused in pediatric patients affected by relapsed/refractory NBL. The phase II extension is aimed at testing the efficacy of the treatment at the optimal dose defined in the phase I, including the patients
    with extremely High-Risk NBL, at greater risk of relapse (namely patients with stage III/IV and MycN amplification) at the end ofthe first-line treatment, even ifthey reached CR.
    L’obiettivo primario di questo studio di fase I è valutare la sicurezza e la fattibilità delle cellule iC9-GD2-CAR T infuse in pazienti pediatrici affetti da Neuroblastoma (NBL) recidivato/refrattario.
    L’estensione della fase II è finalizzata a testare l’efficacia del trattamento alla dose ottimale definita nella fase I, includendo i pazienti con NBL ad altissimo rischio, a maggior rischio di recidiva (ossia i pazienti di stadio III/IV e con amplificazione del gene Myc-N) alla fine del trattamento di prima linea, anche se raggiungono la Remissione Completa (CR).
    E.2.2Secondary objectives of the trial
    l. To assess the in vivo persistence and expansion of the infused T cells in the peripheral blood (PB) and in the BM using immunoassays and transgene detection (Real Time qPCR), both for the whole population and the specific T cells subsets.
    2.
    To evaluate the tumor infiftration ofthe infused T cells through Immunohistochemistry (IRC), flow cytometry and/or transgene detection (Real Time qPCR), whenever the tumor sample is available after the treatment.

    3.
    To evaluate the activationand exhaustion ofthe infused T cells through immunoassays evaluating the expression of the specific markers and their activity through functional assays (such as EUSPOT for IFN-y release using G02-positive and G02-negative target cells, còmparing the response with the T cells at the moment of infusion, when possible)
    4.
    To define the serum cytokine profile and its correlation with CRS in order to define a . possible predictive profile
    1. Valutare la persistenza e l’espansione in vivo delle cellule T infuse, nel sangue periferico (PB) e nel midollo osseo, utilizzando saggi immunologici e la Real Time qPCR per il rilevamento del transgene, sia per l’intera popolazione che per specifiche sottopopolazioni di cellule T.
    2. Valutare l’infiltrazione tumorale delle cellule T infuse mediante Immunoistochimica (ICH), citometria a flusso e/o utilizzando la Real Time qPCR per il rilevamento del transgene, ogni volta che il campione tumorale è disponibile dopo il trattamento.
    3. Valutare l’attivazione e l’esaurimento delle cellule T infuse mediante citofluorimetria per lo studio dell’espressione di specifici markers, e tramite analisi funzionali della loro attività (come ELISPOT per il rilascio dell’IFN-γ utilizzando cellule target GD2-positive and GD2-negative, confrontando la risposta con le cellule T al momento dell’infusione, quando possibile).
