E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to examine the efficacy of multiple doses of ISIS 396443 administered intrathecally in preventing or delaying the need for respiratory intervention or death in infants with genetically diagnosed and presymptomatic spinal muscular atrophy (SMA). |
L’obiettivo primario dello studio è quello di esaminare l’efficacia di ISIS 396443 somministrato in dosi multiple per via intratecale nel prevenire o ritardare il bisogno di intervento respiratorio o decesso nei bambini con diagnosi genetica di SMA in fase presintomatica |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives of this study are to examine the effects of ISIS 396443 in infants with genetically diagnosed and presymptomatic SMA. |
Gli obiettivi secondari di questo studio sono quelli di esaminare gli effetti di ISIS 396443 nei bambini con diagnosi genetica di SMA presintomatica |

ossigeno supplementare o supporto respiratorio).
- Eventuali segni o sintomi clinici allo screening o immediatamente prima
della somministrazione della dose che sono, a giudizio dello sperimentatore, fortemente suggestivi di SMA.

E.5 End points |
E.5.1 | Primary end point(s) |
Time to death or respiratory intervention. The time will be the age of the participant at the first occurrence of either a respiratory intervention or death. Respiratory intervention is defined as invasive or noninvasive ventilation for ≥6 hours/day continuously for 7 or more days OR tracheostomy. |
Tempo al decesso o all’intervento respiratorio. Il tempo sarà l’età del soggetto alla prima ricorrenza di intervento respiratorio o di decesso. L’intervento respiratorio è definito come ventilazione invasiva o non invasiva per ≥6 ore/giorno in modo continuativo per 7 giorni o più O tracheostomia. |
