Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42732   clinical trials with a EudraCT protocol, of which   7035   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    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 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.

    After end of treatment, follow up will document survival status for all patients and disease status for patients in continuing CR, CRp, or CRi. In addition, any nonprotocol treatments for AML will be recorded. Follow-up after the end of treatment will continue until notification that the required number of events (deaths) has occurred. Long-term follow-up is to document survival status on all ongoing patients after notification that the required number of events (deaths) has occurred.
