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   43801   clinical trials with a EudraCT protocol, of which   7263   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
    To assess the efficacy of GWP42003-P as an adjunctive antiepileptic treatment compared with placebo, with respect to the percentage change from baseline during the maintenance period of the study in convulsive seizure frequency. The dose response effect between two GWP42003-P Dose Levels and placebo will also be explored. Convulsive seizures are defined as tonic-clonic, tonic, clonic or atonic and nonconvulsive seizures as myoclonic, partial or absence.
    Evaluar la eficacia de GWP42003-P como tratamiento antiepiléptico complementario comparado con placebo mediante el porcentaje de cambio en la frecuencia de ataques convulsivos respecto al basal en el periodo de mantenimiento del estudio. También se explorará el efecto dosis-respuesta entre dos niveles de dosis de GWP42003-P y el placebo. Los ataques convulsivos se definen como tonicoclónicos, tónicos, clónicos o atónicos y los ataques no consulvivos como mioclónicos, parciales o de ausencia.
    E.2.2Secondary objectives of the trial
    ?To assess changes from baseline in non-convulsive seizure frequency, usage of rescue medication, number of inpatient hospitalizations due to epilepsy, sleep disruption, daytime sleepiness, quality of life and conduct behavioral and cognitive assessments in patients taking GWP42003-P as an adjunctive treatment, when compared with placebo.
    ?To assess the safety of both GWP42003-P doses when compared with placebo.
    ?Evaluar los cambios en la frecuencia, duración de ataques no convulsivos, respecto al basal, uso de medicación de rescate, número de hospitalizaciones debidas a la epilepsia, alteración del sueño, somnolencia diurna, calidad de vida, el comportamiento adaptivo y la función cognitiva en pacientes que toman GWP42003-P como tratamiento complementario, comparado con el placebo.
