E.2 Objective of the trial

E.2.1

Main objective of the trial

The primary objective of this study is to evaluate the long-term safety and tolerability of Padsevonil administered at individualized doses as adjunctive treatment for subjects with drug-resistant epilepsy.

L'objectif principal de cette étude EP0093 est d'évaluer la sécurité, la tolérance et l'efficacité à long terme du Padsevonil en tant que traitement d'appoint des crises focales chez des sujets adultes souffrant d'une épilepsie pharmaco-résistante.

E.2.2

Secondary objectives of the trial

The secondary objective is to evaluate the long-term efficacy of Padsevonil as an adjunctive treatment for focal-onset seizures in adults with drug-resistant epilepsy.

E.2.3

Trial contains a sub-study

E.3

Principal inclusion criteria

- Subject is an adult (18 years of age or more )
- Subject with epilepsy who has completed 1 of the previous Padsevonil (PSL) studies which allow access to the present study
- Female subjects of child bearing potential must have a serum negative pregnancy test at the Entry Visit, which is confirmed to be negative by urine testing prior to further dispensing at each study visit thereafter. Subjects will be withdrawn from the study as soon as pregnancy is known. Female subjects
will use an efficient form of contraception for the duration of the study and for a period of 3 months after their final dose of PSL.

-Le sujet est un adulte (18 ans ou plus).
-Sujet souffrant d'une épilepsie qui a terminé 1 des études précédentes sur le PSL lui permettant d'accéder à la présente étude.
-Les patientes en capacité de procréer doivent obtenir un résultat négatif au test de grossesse sérique lors de la visite d'entrée. Par la suite, le résultat négatif sera confirmé par un test urinaire avant toute distribution de PSL à chaque visite d'étude. Les sujets seront retirés de l'étude dès que la grossesse sera connue.
-Les patientes devront utiliser un type de contraception efficace pendant la durée de l'étude et pour une période de 3 mois après leur dernière dose de PSL

E.4

- Subject has >2x upper limit of normal (ULN) of any of the following: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or >ULN total bilirubin (>= l.5x ULN total bilirubin if known Gilbert's syndrome) at the Entry Visit
- Subject has a clinically-significant abnormality on electrocardiogram (ECG) that, in the opinion of the investigator, increases the risks associated with participating in the study
- Subject has an abnormality on echocardiogram at last echocardiogram assessment, or foreseen in parent study as assessed by central reader that is accompanied by clinical symptoms or a Grade 2* (or higher)/moderate severity abnormality, or a history of rheumatic heart disease, or other known valvular abnormalities (*according to the ASE Guidelines, 2017; Zoghbi et al 2017)
- Female subject who plans to be pregnant or is breastfeeding

-Toute pathologie médicale, neurologique ou psychiatrique grave, ou une valeur de laboratoire pouvant avoir un impact sur la sécurité du sujet.
-Des pensées suicidaires actives comme l'indique une réponse positive (« Oui ») à la question 4 ou à la question 5 de la version « Depuis la dernière visite » de la Columbia-Suicide Severity Rating Scale (C-SSRS, échelle d'évaluation de la gravité du risque de suicide de Columbia).
-patient ayant plus de 2 x la limite supérieure de la normale (ULN) pour l'un des taux suivants : alanine aminotransférase (ALT), aspartate aminotransférase (AST), phosphatase alcaline (ALP), ou bilirubine totale > ULN (bilirubine totale ≥ 1,5 x ULN si syndrome de Gilbert connu) lors de la visite d'entrée.
-Patient ayant une anomalie cliniquement significative de l'électrocardiogramme (ECG) qui, selon l'avis de l'investigateur, augmente les risques associés à la participation à l'étude
- Patient ayant une anomalie de l'échocardiogramme lors de la dernière évaluation de l'échocardiogramme, ou détectée lors de l'étude parent et évaluée par le lecteur central, accompagnée de symptômes cliniques (par exemple, essoufflement, palpitations et souffle), une anomalie de grade 2* (ou supérieure)/de gravité modérée, des antécédents de cardiopathie rhumatismale ou d'autres anomalies valvulaires connues
(*selon les ASE Guidelines, 2017; Zoghbi et al 2017)
-Les patientes qui envisagent une grossesse ou qui allaitent.
