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   43874   clinical trials with a EudraCT protocol, of which   7294   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.

    10.Capable of giving signed informed consent as described in Appendix 1 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
    11.Willingness to comply with scheduled study visits, procedures, and treatment plan.
    1. Adulti di età compresa tra 18 e 75 anni con LMA de novo non trattata in precedenza, LMA con caratteristiche della SMD o LMA correlata alla terapia.
    2. Malattia con mutazione di NPM1 documentata in una struttura di analisi locale o centrale dello sponsor.
    Nota: Possono essere arruolati anche soggetti con mutazione FLT3 concomitante ma senza accesso a midostaurina (ad es., per mancanza di approvazione o rimborso da parte dell’autorità sanitaria); i soggetti con una mutazione FLT3 concomitante non potranno ricevere un inibitore FLT3 in alcun momento durante il periodo di trattamento dello studio.
    Nota: I soggetti con risultati del test locale per NPM1-m (e/o stato mutazionale di FLT3) possono essere arruolati, a condizione che vengano inviati opportuni campioni alla struttura di analisi centrale dello sponsor per lo sviluppo diagnostico associato a NPM1-m (vedere Sezione 4.1).
    3. Punteggio dello stato di validità secondo il Gruppo orientale cooperativo di oncologia (ECOG) pari a 0, 1 o 2.
    4. Funzionalità epatica e renale adeguata, definita come segue:
    a. Aspartato aminotransferasi (AST) e alanina aminotransferasi (ALT) sierica < 2,5 volte il limite superiore della norma (ULN), ad eccezione di quelli con coinvolgimento epatico da parte della LMA, come documentato da tomografia computerizzata (TC) o ecografia, nei quali sono accettabili livelli di AST e ALT < 5 volte l’ULN; bilirubina totale < 1,5 volte l’ULN, a meno che non sia elevata a causa della malattia di Gilbert o dell’emolisi.

    E.5 End points
    E.5.1Primary end point(s)
    MRD negative complete response (CR) rates after completion of 2 cycles of chemotherapy plus either ENTO or placebo.
    Note: MRD negative CR requires CR as defined by the European Leukemia Network (ELN) 2017 criteria (with minor modification for neutrophil and
    platelet count thresholds as defined by the International Working Group [IWG]) as assessed by study site investigators, and MRD negativity (<0.01%) in bone marrow as measured by a molecular NPM1-m assay (eg, by next generation sequencing) in a central laboratory upon recovery of peripheral blood counts following completion of 2 cycles of chemotherapy (ie, no later than Day 42 of Cycle 2).
    Tassi di risposta completa (CR) MRD-negativa dopo il completamento di 2 cicli di chemioterapia più ENTO o placebo.
    Nota: Per “CR MRD-negativa” si intende una CR definita in base ai criteri della European Leukemia Network (ELN) 2017 (con modifiche minori per il limite della conta dei neutrofili e delle piastrine secondo la definizione del Gruppo di lavoro internazionale [International Working Group - IWG]) in base alla valutazione degli sperimentatori del centro dello studio e la negatività MRD (<0,01%) nel midollo osseo viene misurata mediante un test molecolare di NPM1-m (ad es. mediante sequenziamento di nuova generazione) in un laboratorio centrale al recupero delle conte di sangue periferico dopo il completamento di 2 cicli di chemioterapia (ovvero, non oltre il Giorno 42 del ciclo 2).
    E.5.1.1Timepoint(s) of evaluation of this end point
    During the course of the study
    Nel corso dello studio
    E.5.2Secondary end point(s)
    • Event-free survival, defined as the time from randomization to the earliest occurrence of induction treatment failure, relapse from CR, or death from any cause.
    Note: Induction treatment failure is failure to achieve morphological CR after completion of the last cycle of induction chemotherapy (no later than Day 42 of the last cycle of induction).
    • Relapse-free survival, defined as the time from CR until relapse or death from any cause as assessed by study site investigators.
    • Overall survival defined as the time from randomization until death from any cause.
    • CR rates after 2 cycles of chemotherapy, as defined by ELN 2017 criteria (with minor modification for neutrophil and platelet count thresholds as defined by the IWG) as assessed by study site investigators.
    • Type, incidence, severity, and outcome of adverse events; changes from baseline in safety laboratory assessments, ECGs, ECHO/MUGA scans, ECOG PS.
    - Sopravvivenza libera da eventi, ovvero il tempo dalla randomizzazione alla prima insorgenza di fallimento del trattamento di induzione, recidiva da CR o decesso per qualsiasi causa.
    Nota: Il fallimento del trattamento di induzione è il mancato raggiungimento della CR morfologica dopo il completamento dell’ultimo ciclo di chemioterapia di induzione (non oltre il Giorno 42 dell’ultimo ciclo di induzione).
    - Sopravvivenza libera da recidiva, ovvero il tempo trascorso dalla CR fino alla recidiva o al decesso per qualsiasi causa, valutata dagli sperimentatori del centro dello studio.
    - Sopravvivenza complessiva, ovvero il tempo dalla randomizzazione al decesso per qualsiasi causa.
    - Tassi di CR dopo 2 cicli di chemioterapia, definiti in base ai criteri ELN 2017 (con modifiche minori per i limiti di conta di neutrofili e piastrine secondo la definizione dell’IWG) come valutati dagli sperimentatori del centro dello studio.
    - Tipo, incidenza, gravità ed esito degli eventi avversi; variazioni rispetto al basale nelle valutazioni di laboratorio di sicurezza, ECG, scansioni ECO/scansione con acquisizione a gate multipli (MUGA), stato di validità (PS) ECOG.
