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   43850   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.5 End points
    E.5.1Primary end point(s)
    Primary efficacy variable is the rate of composite complete response (CRc). Definition of CRc:  Composite Complete Remission Rate (CRc): Defined as the confirmed remission rate of all complete and incomplete CRs (i.e., CR + CRp + CRi).  Complete Remission (CR): For subjects to be classified as being in CR, they must have bone marrow regenerating normal hematopoietic cells and achieve a morphologic leukemia-free state and must have an absolute neutrophil count (ANC) > 1x10e9/L and platelet count > 100 x 10e9/L, and normal marrow differential with < 5% blasts, and they will be red blood cell (RBC) and platelet transfusion independent (defined as 4 weeks without RBC transfusions and 1 weeks without platelet transfusion). There should be no evidence of extramedullary leukemia.  Complete Remission with Incomplete Platelet Recovery (CRp): For subjects to be classified as being in CRp, they must achieve CR except for incomplete platelet recovery (< 100 x1e9/L).  Complete Remission with Incomplete Hematologic Recovery (CRi): For subjects to be classified as being in CRi, they must achieve CR except for incomplete hematological recovery with residual neutropenia <1 x 10e9/L with or without complete platelet recovery. RBC and platelet transfusion independence is not required. Primary safety variable is the rate of Grade 2 or higher QTcF prolongation. Definition of QTcF prolongation, Grade ≥2 ECGs will be recorded in triplicate (3 separate 12-lead ECGs at least 5 minutes apart per time point) and the Fridericia's correction of the QT interval (QTcF) will be calculated based on the average of all the ECGs obtained around that time point. QTcF grading will be done according to CTCAE v. 4.03, and the definition of greater than Grade 2 prolongation is QTcF ≥ 480 ms. Secondary safety variables are:  Adverse Events (AEs)  Serum chemistry, hematology, and urinalysis  Vital sign measurements  ECGs  ECOG performance scores
    La variabile di efficacia primaria e' il tasso composito di risposta completa (CRc). Definizione di CRc: • Tasso composito di remissione completa (CRc): tasso di remissione confermato di tutte le CR complete e incomplete (ossia CR + CRp + CRi). • Remissione completa (CR): per essere classificati in CR, i soggetti devono mostrare un midollo osseo in grado di rigenerare cellule ematopoietiche normali e raggiungere uno stato morfologico senza leucemia, nonche' avere una conta assoluta dei neutrofili (ANC) > 1 x 109/l e una conta piastrinica ≥ 100 x 109/l e una diagnosi differenziale del midollo normale con < 5% di blasti, e si trattera' di cellule ematopoietiche non dipendenti dalle trasfusioni di globuli rossi (RBC) e piastrine (inteso come 4 settimane senza trasfusioni di RBC e 1 settimana senza trasfusione di piastrine). Non dovra' emergere alcun segno di leucemia extramidollare. • Remissione completa con recupero piastrinico incompleto (CRp): per essere classificati in CRp, i soggetti devono ottenere una CR, eccetto che per il recupero piastrinico incompleto (< 100 x109/l). • Remissione completa con recupero ematologico incompleto (CRi): per essere classificati in CRi, i soggetti devono ottenere una CR, eccetto che per il recupero ematologico incompleto con neutropenia residua < 1 x 109/l con o senza recupero piastrinico completo. L’indipendenza dalla trasfusione di RBC e piastrine non e' richiesta. La variabile di sicurezza primaria e' il tasso di prolungamento di QTcF di Grado 2 o superiore. Definizione di prolungamento di QTcF, di Grado ≥2: Gli ECG saranno registrati in tre intervalli (3 diversi ECG a 12 derivazioni a distanza di almeno 5 minuti per ciascun punto temporale) e (il QTcF) sara' calcolato in base alla media di tutti gli ECG ottenuti attorno a quel punto temporale. La classificazione in gradi del QTcF sara' effettuata in base al CTCAE v. 4.03; la definizione di prolungamento maggiore del Grado 2 e' QTcF ≥ 480 ms. Variabili di sicurezza secondaria • Eventi avversi • Valori ematochimici ed ematologici e analisi dell’urina • Parametri vitali • Risultati ECG • Punteggio di ECOG PS

Exploratory Variables Inhibition of phosphorylation of FLT3 and STAT5 will be determined using whole blood samples
    Variabili secondarie di efficacia: • Remissione completa (CR) • Sopravvivenza globale (OS) • Sopravvivenza libera da eventi (EFS) • Sopravvivenza libera da leucemia (LFS) • Durata della remissione Farmacocinetica  Nei pazienti con campioni per la PK sufficienti al Giorno 1 del Ciclo 1 e al Giorno 15 del Ciclo 1 saranno stimati i parametri di PK per AC220 e AC886 incluso il calcolo di AUC24, Cmax, Cmed e tmax.  La modellazione della PK di popolazione sara' effettuata per AC220 e il suo metabolita attivo AC886 Farmacogenetica  Valutazione dello stato di FLT3-ITD del rapporto alellico  Determinazione delle mutazioni nei domini JM e TK di FLT3, FLT3-ITD e C-KIT in campioni di midollo osseo e sangue intero.

    F.5 Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)
    After treatment discontinuation, subjects will be followed for 30 days for safety, after which the subjects will enter long-term follow up for collection of subsequent AML treatment, remission status, and survival (cause of death and date of death). Any other treatment or care will be discussed with the investigator.
    Al termine del trattamento, i pazienti saranno seguiti per 30 giorni per la safety, dopo di che entreranno nel periodo di follow-up a lungo termine per la registrazione di successivi trattamenti per la AML, lo stato di remissione e la sopravvivenza (causa e datta del decesso). Ogni altro trattamento o cura sara' discussa con lo sperimentatore.
