E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To show relevant beneficial effect of BF2.649 on EDS compared to placebo in add on to sodium oxybate in narcoleptic patients with residual EDS. This trial will characterize the efficacy of BF2.649 compared to placebo in showing an incremental improvement to the situation achieved by the use of sodium oxybate particularly in terms of a reduction of EDS as measured by the Epworth Sleepiness scale (ESS). In addition the change in the average number of cataplexy attacks per week will be assessed. |
Mostrar el efecto beneficioso relevante del BF2.649 en la SDE en comparación con el placebo agregado al oxibato de sodio en pacientes narcolépticos con SDE residual. Este ensayo caracterizará la eficacia del BF2.649 en comparación con el placebo al mostrar una mejora creciente de la situación que se logra mediante el uso del oxibato de sodio, especialmente en términos de una reducción de la SDE, medida por la Escala de somnolencia de Epworth (ESS). Además, se evaluará el cambio en la cantidad promedio de ataques de cataplejía por semana. |
