new on-treatment T1-gadolinium-enhancing (Gd+) lesions to persistent black holes (PBH) over 52 weeks. |
L’obiettivo primario dello studio consiste nel valutare l’effetto di natalizumab rispetto a fingolimod sull’evoluzione delle nuove lesioni captanti il gadolinio (Gd+) in T1 durante il trattamento ai buchi neri persistenti (persistent black holes, PBH) nell’arco di 52 settimane |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are to assess the effect of natalizumab compared to fingolimod on:
• MRI measures of CNS tissue destruction as measured by the number of new T1-Gd+ lesions.
• Various other MRI measures of disease activity.
• No Evidence of Disease Activity (NEDA)
• Relapse on treatment over 52 weeks.
• The change in information processing speed as measured by the Symbol Digit Modalities Test (SDMT). |
Gli obiettivi secondari di questo studio consistono nella valutazione dell’effetto di natalizumab rispetto a fingolimod sui seguenti aspetti:
• Misurazioni mediante RMI in termini di danno tissutale a livello del SNC, in base al numero di nuove lesioni Gd+ in T1.
• Varie altre misurazioni dell’attività di malattia mediante RMI.
• Nessuna evidenza di attività della malattia
• Recidiva durante il periodo di trattamento nell’arco di 52 settimane.
• Variazioni nella velocità di elaborazione delle informazioni, in base al test delle modalità simboli e cifre (Symbol Digit Modalities Test, SDMT). |
