|
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 | No |
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 Subjects will be withdrawn from the study as soon as pregnancy is known.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 |
- Soggetto adulto (età =18 anni) - Soggetto con epilessia che ha completato 1 degli studi precedenti su padsevonil (PSL) che consentono l’accesso al presente studio - I soggetti di sesso femminile in età fertile devono risultare negativi a un test di gravidanza sul siero eseguito alla Visita di ingresso e il risultato negativo deve essere confermato prima dell’ulteriore dispensazione da un test sulle urine eseguito a ogni successiva visita dello studio. I soggetti saranno ritirati dallo studio non appena venga resa nota una gravidanza. I soggetti di sesso femminile devono utilizzare un metodo contraccettivo efficace per la durata dello studio e per un periodo di 3 mesi dopo l’ultima dose di PSL |
