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   43841   clinical trials with a EudraCT protocol, of which   7281   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.

    • To demonstrate that the ZX008 0.2 and 0.8 mg/kg/day dose groups are (independently) superior to placebo on the following endpoints:
    - The proportion of subjects who achieve a ≥40% reduction from baseline in convulsive seizure frequency.
    - The proportion of subjects who achieve a ≥50% reduction from baseline in convulsive seizure frequency.
    - The longest convulsive seizure-free interval.

    Please refer to the Clinical Study Protocol, Section 2 Study Objectives and Endpoints for complete list of Secondary Endpoints
    • Demostrar que una dosis de 0,2 mg/kg/día de ZX008 es superior al placebo como tratamiento complementario del síndrome de Dravet de acuerdo con los cambios producidos en la frecuencia de las crisis convulsivas entre el inicio y A+M.
