    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Molecular confirmation of a pathogenic or likely pathogenic PCDH19 variant. The principal investigator (PI) must review the results of the
    genetic analysis and confirm that the causal relationship to the epilepsy syndrome is likely. If the subject has a de novo variant of unknown
    significance (VUS) then the central assessor, PI, and Sponsor will review
    study inclusion. Genetic mutations will be confirmed by the sponsor's
    chosen central laboratory.
    2. Female subjects aged 1 through 17 years, inclusive.
    3. Subject/parent or LAR willing to give written informed consent/assent, after being properly informed of the nature and risks of

Focal and generalized nonmotor seizures and myoclonic seizures do not count as the primary seizure types.
    6. Subject must be approved to participate by sponsor or its designee (eg, Epilepsy Consortium) after review of medical history, genetic
    testing, seizure classification video (if available), and historical seizure calendars.
    7. Subjects should be on a stable regimen of anti-seizure medications, if any, for = 1 month prior to the screening visit, without a foreseeable change in dosing for the duration of baseline and the DB phase. Vagus nerve stimulator (VNS), ketogenic diet, and modified Atkins diet should be unchanged for 3 months prior to screening
    8. Subjects with surgically implanted VNS will be allowed to enter the study provided that all of the following conditions are met:
    • The VNS has been in place for = 1 year prior to the screening visit.

    11. Sexually active female of childbearing potential must be using a medically acceptable method of birth control and have a negative quantitative serum ß-human chorionic growth hormone (ß-HCG) test collected at the initial screening visit. Childbearing potential is defined as a female who is biologically capable of becoming pregnant. A medically acceptable method of birth control includes intrauterine devices in place for at least 3 months prior to the screening visit, surgical sterilization, or adequate barrier methods (eg, diaphragm and foam). An oral contraceptive alone is not considered adequate for the purpose of this study. Use of oral contraceptives in combination with another method (eg, a spermicidal cream) is acceptable. In subjects who are not sexually active, abstinence is an acceptable form
    1.Conferma molecolare di variante patogenetica o verosimilmente patogenetica di PCDH19. Lo sperimentatore principale (PI) deve esaminare i risultati dell’analisi genetica e confermare la probabile relazione causale con la sindrome epilettica. Qualora il soggetto presenti una variante de novo di significato non noto (VUS), la sua inclusione nello studio sarà vagliata dal valutatore centrale, dal PI e dallo sponsor. Le mutazioni genetiche saranno confermate dal laboratorio centrale scelto dallo sponsor.
    2.Soggetti femminili di età da 1 a 17 anni, compresi.

I tipi primari di crisi convulsive sono definiti come crisi convulsive focali quantificabili con ipotonia progressiva e alterazione dello stato di coscienza, oppure qualsiasi crisi convulsiva quantificabile, focale o generalizzata, con una chiara componente motoria. Le crisi convulsive focali e generalizzate non motorie e le crisi convulsive miocloniche non rientrano nei tipi primari di crisi convulse.
    6.La partecipazione del soggetto deve essere approvata dallo sponsor o da un delegato (per es., Epilepsy Consortium [Consorzio per lo studio dell’epilessia]) dopo revisione dell’anamnesi medica, dei risultati del test genetico, della registrazione video per la classificazione delle crisi convulsive (ove disponibile) e dei diari anamnestici delle crisi convulsive.
    7.Se in trattamento con farmaci anticonvulsivanti, i soggetti devono seguire un regime stabile da =1 mese prima della visita di screening, senza alcuna modifica prevedibile nel dosaggio per tutta la durata del basale e della fase DB. L’eventuale terapia con SNV, dieta chetogenica e dieta di Atkins modificata non deve subire modifiche nei 3 mesi precedenti lo screening
    8.I soggetti con SNV impiantato chirurgicamente potranno accedere allo studio a condizione che siano soddisfatte tutte le condizioni elencate di seguito:
    • L’SNV è stato impiantato =1 anno prima della visita di screening.
    • Le impostazioni devono essere rimaste costanti nei 3 mesi precedenti la visita di screening e rimanere costanti per tutta la durata del basale e della fase DB.

Si definisce in età fertile una donna biologicamente in grado di rimanere incinta. I metodi contraccettivi clinicamente accettabili includono dispositivi intrauterini in sede da almeno 3 mesi prima della visita di screening, la sterilizzazione chirurgica oppure metodi barriera adeguati. L’uso di un contraccettivo orale da solo non è considerato adeguato ai fini di questo studio. È considerato accettabile l’uso di contraccettivi orali in combinazione con un altro metodo. L’astinenza rappresenta una forma accettabile di contraccezione nei soggetti non sessualmente attivi.
