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 ).

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to compare overall survival (OS) between treatment groups of patients treated with vosaroxin and cytarabine versus patients treated with placebo and cytarabine.
    E.2.2Secondary objectives of the trial
    - Compare complete remission (CR) rate based on International Working Group (IWG) response criteria, between treatment groups
    - Compare safety and tolerability between treatment groups
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    The following substudy will be conducted at sites in the United States and Canada only:

    Electrocardiographic and pharmacokinetic substudy (addendum to protocol VOS-AML-301). Original addendum, dated 03 September 2010.

    Approximately 30 patients in each treatment group will participate in this substudy, at approximately 15 to 20 study sites. The effect on cardiac repolarization, as measured by QTcF, will be evaluated for patients treated with vosaroxin (90 mg/m2, the highest dose administered in the study) versus placebo in combination with cytarabine. On days 1 and 4 of induction 1, digital 12-lead ECGs will be recorded continuously using a Holter monitor before each vosaroxin or placebo dose through 23 hours after the start of study drug administration. The ECGs will be read and the assessment of QTc will be performed by a cardiologist blinded to treatment assignment at a central cardiac safety services facility.

    Sparse time-matched blood samples will be obtained to determine concentrations of vosaroxin, cytarabine, and their relevant metabolites for PK and PK-PD evaluation.

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint is overall survival (OS) in the intent-to-treat population. Analysis of OS will be based on the log-rank test weighted to account for the adaptive design. Kaplan-Meier methods will be used to estimate OS for each treatment group. Sensitivity analyses will be performed to assess the effect of subsequent therapy, and specifically transplantation, on OS.

    The primary safety endpoint is 30- and 60-day all cause mortality, summarized with point estimates and 95% confidence intervals.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The primary endpoint analyses will be conducted after the required number of events (deaths) has occurred (375).

    One formal interim efficacy analysis will be performed after reaching 187 events (deaths) (50% of the required number of 375 events). At the discretion of the data and safety monitoring board (DSMB), one of the following actions will be taken at the interim analysis: terminate for efficacy, terminate for futility, increase the accrual to a maximum of 750 patients and extend the observations in the study beyond the prespecified 375 events, or continue the study as planned.
    E.5.2Secondary end point(s)
    The secondary efficacy endpoint is complete remission rate, defined as the percentage of patients whose response is a complete remission based on IWG response criteria.

    The secondary safety endpoint is the incidence of AEs.
    E.5.2.1Timepoint(s) of evaluation of this end point
    The secondary endpoint analysis will be conducted after the required number of events (deaths) has occurred (375).

    One formal interim efficacy analysis will be performed after reaching 187 events (deaths) (50% of the required number of 375 events). At the discretion of the data and safety monitoring board (DSMB), one of the following actions will be taken at the interim analysis: terminate for efficacy, terminate for futility, increase the accrual to a maximum of 750 patients and extend the observations in the study beyond the prespecified 375 events, or continue the study as planned.
