E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the maintenance of the efficacy of EPI-743 in patients with Leigh syndrome, who previously received EPI-743 and who continue to benefit from the use of EPI-743, on disease severity as assessed by combined scores of the Newcastle Pediatric Mitochondrial Disease Scale (NPMDS) sections 1-3. |
Valutare il mantenimento dell’efficacia dell’EPI-743 in pazienti affetti dalla sindrome di Leigh, che sono già stati in trattamento con il prodotto sperimentale e che continuano a beneficiare dal trattamento con EPI-743, attraverso la valutazione dei punteggi combinati delle sezioni 1 – 3 del questionario Newcastle Mitochondrial Disease Scale (NPMDS). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the maintenance of the efficacy of EPI-743 in patients with Leigh syndrome, who previously received EPI-743 and who continue to benefit from the use of EPI-743, on: 1.Neuromuscular function 2.Respiratory function 3.Disease morbidity and mortality To evaluate the long-term safety of EPI-743 in patients with Leigh syndrome who previously received EPI-743. |
Valutare il mantenimento dell’efficacia dell’EPI-743 in pazienti affetti dalla sindrome di Leigh, che sono già stati in trattamento con il prodotto sperimentale e che continuano a beneficiare dal trattamento con EPI-743, per quanto riguarda: 1.Funzione neuromuscolare 2.Morbilità e Mortalità della malattia 3.Funzione respiratoria 4. Valutare la sicurezza a lungo termine dell’ EPI-743 in pazienti affetti dalla sindrome di Leigh e che sono già stati in trattamento con il prodott |
