|
E.2.2 | Secondary objectives of the trial |
Secondary objectives of this study are to assess the safety and tolerability of BIIB023 compared with placebo in this study population. |
Gli obiettivi secondari di questo studio sono quelli di valutare la sicurezza e la tollerabilità di BIIB023 rispetto al placebo in questa popolazione dello studio. |
