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   44334   clinical trials with a EudraCT protocol, of which   7366   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.

    General information about the trial
    Main objective of the trial
    Primary Efficacy Objective • To assess event-free survival (EFS) after intensive induction (daunorubicin and cytarabine) and consolidation (high-dose cytarabine) chemotherapy with or without dasatinib in patients with CBF-AML Secondary Objectives • To assess the interaction between type of CBF-AML [t(8;21) 3versus inv(16)] and randomization accordingly on all survival endpoints • To assess cumulative incidence of relapse (CIR) and death (CID) • To assess relapse-free (RFS) and overall survival (OS) • To assess outcome according to KIT mutational status • To assess pharmacodynamic inhibition of KIT • To assess toxicity
    Protection of trial subjects
    In this study, safety was assessed by evaluating the following: reported adverse events, clinical laboratory test results, vital signs measurements, ECG findings, chest X-ray, echo scan, physical examination findings, monitoring of concomitant therapy. For each safety parameter, all findings (whether normal or abnormal) were recorded in the eCRF.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: N=204 patients were enrolled overall into the trial. Two patients were excluded due to violation of inclusion/exclusion criteria (invalid informed consent) and therefore were not included into the Intention-to-treat population which represents the baseline population.

    End point description
    The primary endpoint of the study was event-free survival; an event was defined as one of the following: • Refractory disease, defined as failure to achieve at least a PR after the first induction cycle and CR or CRi after an optional second induction cycle • Death by any cause • Hematologic Relapse • Molecular persistence • Molecular relapse.

    Notes
    [5] - Multivariable analysis models were adjusted for the following potential prog- nostic covariates: • Age, Sex • Eastern Cooperative Oncology Group (ECOG) status (0-1 vs. 2+) • WBC (log-10 transformed) • KIT mutation status • FLT3 mutation status • AML Type (de novo vs.secondary/therapy-related) • CBF type (inv(16) vs. t(8;21)) • Minimal residual disease status (MRD at low level/negative vs. positive as time-dependent covariate)
    [6] - No signifcant treatment effect, but negative effect on EFS for higher white blood cell count (HR for log10 increase 2.21; p<.001), KIT status (HR 2.15; p<.001) and presence of CBF-AML type t(8;21) (HR 1.58; p=0.048).

    Cumulative incidence of relapse (CIR)
    End point description
    The analyses of CIR and CID are restricted to patients in the ITT population who achieved CR/CRi. CIR and CID are analysed using a competing risks model for time to relapse (TTR) and non- relapse mortality (NRM). TTR is defined as the time from first CR/CRi to until hematologic/ molecular relapse or molecular persistence. Deaths in remission are considered as a competing event. NRM is defined as the time from achievement of a remission (CR/CRi) to death without prior re- lapse or molecular persistence. Relapse or molecular persistence after achieving CR/CRi are considered as a competing event. Patients who are not known to have relapsed, being molecularly persistent or died are censored at the date of last clinical response assessment for both endpoints.

    Event-free survival additionally was analyzed utilizing the following alternative definition of EFS: EFS was calculated as the time from randomization until failure to achieve CR or CRi after induction, death after achieving CR or CRi, or relapse after achieving CR or CRi, whichever comes first. Patients without CR/CRi after induction were considered as events at the date of the assessment confirming no CR/CRi (as opposed to the original definition of EFS, where patients without CR/CRi after induction were considered as having events at day 1 of randomization). Patients still in first CR/CRi and alive or lost to follow-up wer censored at the date of last response evaluation.
