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   43862   clinical trials with a EudraCT protocol, of which   7285   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)
    EXPLORATORY PHASE II AND CONFIRMATORY PHASE III:
    There are 2 primary endpoints in the study: one regarding Efficacy and one regarding Safety. The study will be declared positive if the 2 primary endpoints are met.
    Primary endpoint of efficacy
    The initially specified endpoint for efficacy was :
    - Efficacy endpoint at end of F2 block (or VANDA) (i.e. Day 28):
    • Mean duration of asparagine depletion in days throughout F1-F2 blocks.
    Asparagine depletion will be defined as plasmatic asparagine concentration ≤ 2µM.

    According to the CHMP advice, this efficacy endpoint was revised to :
    - Efficacy endpoint at end of induction phase (i.e. day 28):
    • Duration in days of asparaginase activity >100 IU/L.

    Primary endpoint of safety
    • Toxicity endpoint at end of F2 block (or VANDA) : Incidence of allergic reaction, whatever the grade.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Timepoint(s) of evaluation of Primary end points described in E.5.1
    E.5.2Secondary end point(s)
    EXPLORATORY PHASE II
    • Molecular response rate (MRD).
    • Percentage of CR patients at F2 block ending.
    • Biological and clinical toxicity according to NCI-CTCAE (version 3.0) grading, in particular pancreatic, hepatic toxicity, deep vein thrombosis and other coagulation disorders, which are well known adverse events related to L-asparaginase.
    • Plasma concentrations of asparagine, aspartate, glutamine, glutamate and asparaginase.
    • Percentage of patient presenting with asparagine depletion (i.e. ≤ 2µM) at different time points.

    CONFIRMATORY PHASE III:
    Secondary endpoints listed above are still used and the following are added:
    • Number of patients with adequate asparagine depletion (i.e. ≤ 2 µM) and without allergic reaction during the induction phase.
    • Number of patients with asparaginase activity >100 IU/L and without allergic reaction during the induction phase.
    • Specific anti-L-asparaginase antibodies level.
    • Ratio of performed / planned injections regarding GRASPA® and reference asparaginase treatment over the total mean duration of study treatment.
    • At 6, 12, 24, 36 months:
    o Event free survival rate
    o Relapse free survival rate
    o Overall survival rate.
