E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether Rapamycin administration increases Tregs number in treated patients compared to control arm |
Valutare se Rapamicina determina un aumento dei linfociti Treg in pazienti affetti da SLA rispetto al braccio di controllo |
|
E.2.2 | Secondary objectives of the trial |
To assess safety and tolerability of Rapamycin in ALS patients; to assess the minimum dosage to have RAPAMYCIN in CSF; to assess changes in immunological (activation and homing of T,B,NK cell subpopulations) and inflammatory markers, and on mTOR downstream pathway (S6RP phosphorylation); to assess clinical activity (ALSFRS-R, survival, FVC) and effect on quality of life (ALSAQ40). To assess if and at what dosage Rapamycin passes through blood brain barrier (BBB). |
Valutare sicurezza e tollerabilità di Rapamicina in pazienti con SLA; valutare eventuali cambiamenti a livello di marcatori biologici del sistema immunitario (attivazione e homing dei linfociti T, B e NK), di infiammazione e a livello della cascata di segnali correlata alla proteina mTOR (fosforilazione di S6RP); valutare l’effIicacia clinica (tramite ALSFRS-R, sopravvivenza e FVC) di Rapamicina rispetto al placebo e l’effetto sulla qualità della vita (mediante ALSAQ40); valutare se e a che dosaggio Rapamicina attraversa la barriera ematoencefalica. |
