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   43800   clinical trials with a EudraCT protocol, of which   7272   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.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of clinical part of EPISTOP project is to identify the clinical and molecular biomarkers of epileptogenesis in a prospective clinical study of patients with TSC.
    Het primaire doel van de EPISTOP trial is om klinische en moleculaire biomarkers van epileptogenese te identificeren, in een prospectieve klinische studie bij zuigelingen met TSC.
    E.2.2Secondary objectives of the trial
    Secondary objective of the clinical part of EPISTOP is to compare the effects of standard antiepileptic treatment in patients diagnosed as having epilepsy after clinical seizures vs after electroencephalographic epileptiform discharges, in a randomized trial in TSC patients.
    Het secundaire doel van de EPISTOP trial is om het effect van vroege behandeling - na het ontstaan van epileptiforme EEG afwijkingen - te vergelijken met het effect van standaard behandeling - na het ontstaan van klinische aanvallen -, in een randomized controlled trial.

    E.3Principal inclusion criteria
    - Male or female infants with a definite diagnosis of TSC (Roach criteria; Roach 1998 or DNA confirmed),

    E.5 End points
    E.5.1Primary end point(s)
    Primary endpoint of the study is the collection of a set of molecular and clinical biomarkers in full analysis set of patients, including all TSC infants participating in the study and the control subjects.
    De primaire uitkomstparameter van de studie is de collectie van een set van moleculaire en klinische biomarkers, bij alle deelnemers aan het onderzoek, zowel kinderen met TSC, als controles.
    E.5.1.1Timepoint(s) of evaluation of this end point
    vEEG will be performed every 4 weeks (± 1 week) in the children under the age of 6 months, then every 6 weeks (± 1 week) in children under 12 months, and every 8 weeks (± 1 week) thereafter.
    MRI will be performed at baseline (unless patient had an MRI performed within 1 month before baseline visit and an additional scan cannot be performed without general anaesthesia) and then as clinically indicated, but not later than at the age of 2 years.
    Neuropsychological assessment using a specially designed targeted battery of test will be performed every 6 months.
    Blood samples will be collected at study entry, at the onset of epileptiform discharges on vEEG or at the age of 6 months, whichever is applicable, at the onset of clinical seizures and at the end of follow-up (age 2 years)
    Er zal elke 4 weken (± 1 week) een videovEEG gemaakt worden bij kinderen jonger dan 6 maanden; daarna elke 6 weken (± 1 week) bij kinderen jonger dan 12 maanden en daarna elke 8 weken tot het einde van de follow-up.
    Er zal bij inclusie een MRI-hersenen gemaakt worden (tenzij de patient binnen een maand voor de baseline visit een MRI heeft ondergaan en een extra scan niet kan worden uitgevoerd zonder algehele anesthesie) en daarna wanneer klinisch geïndiceerd, maar niet later dan op de leeftijd van 2 jaar.
    Neuropsychologisch onderzoek zal elke 6 maanden plaatsvinden.
    Bloedafname zal plaatsvinden bij inclusie, bij het ontstaan van epileptiforme afwijkingen op het EEG of op de leeftijd van 6 maanden, bij de start van klinische aanvallen en aan het einde van de follow-up (2 jaar).
    E.5.2Secondary end point(s)
    Key secondary endpoint is better efficacy of antiepileptic treatment in patients diagnosed as epileptic after electroencephalographic epileptiform discharges in comparison to patients diagnosed as having epilepsy after the onset of clinical seizures.
    De belangrijkste secundaire uitkomstparameter is het vaststellen van het meest effectieve moment van behandelen: na het ontstaan van epileptiforme EEG afwijkingen of na het ontstaan van klinische aanvallen.
    E.5.2.1Timepoint(s) of evaluation of this end point
    The parameters of efficacy assessment include: the distribution of seizure free patients, proportion of patients with drug resistant seizures, proportion of patients with normalized EEG, the neuropsychological outcome recognized as the results in a battery of tests performed at the age of 24 months.
    Parameters van effectiviteit omvatten de volgende: de verdeling van aanvalsvrije patienten, de proportie patienten met refractaire epilepsie, de proportie patienten met een genormaliseerd EEG en de uitkomsten van neuropsychologisch onderzoek op de leeftijd van 24 maanden.
