E.1.1.1 | Medical condition in easily understood language |
PSP is a disease that attacks the brain, causing problems with body movement, memory, thinking, and behavior. Symptoms get worse over time and eventually make doing normal, daily tasks impossible. |
PSP è una malattia che attacca il cervello,causando probl.con il movim.del corpo,memoria,pensiero e comportamento.I sintomi peggiorano nel tempo e alla fine rendono le norm.attività quotid.impossibili |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To assess the efficacy of ABBV-8E12 in slowing disease progression in subjects with progressive supranuclear palsy as measured by the PSP Rating Scale (PSP-RS). - To assess the long term safety and tolerability of ABBV-8E12 for up to 52 weeks in subjects with progressive supranuclear palsy. |
- Valutare l’efficacia di ABBV-8E12 nel rallentare la progressione della malattia in soggetti affetti da paralisi sopranucleare progressiva mediante la scala di valutazione PSP (PSP-RS). - Valutare la sicurezza e la tollerabilità a lungo termine di ABBV-8E12 per un massimo di 52 settimane in soggetti affetti da paralisi sopranucleare progressiva. |
|
E.2.2 | Secondary objectives of the trial |
- To assess the pharmacokinetics of ABBV-8E12 in subjects with PSP. - To assess the efficacy of ABBV-8E12 in slowing disease progression and functional impairment in subjects with PSP as measured by secondary endpoints. - To assess the efficacy of ABBV-8E12 in slowing regional and/or whole brain atrophy in subjects with PSP as measured by volumetric MRI. |
- Valutare la farmacocinetica di ABBV-8E12 in soggetti affetti da paralisi sopranucleare progressiva. - Valutare l’efficacia di ABBV-8E12 nel rallentare la progressione della malattia e il deterioramento funzionale in soggetti affetti da paralisi sopranucleare progressiva come misurato dagli endpoints secondari. - Valutare l’efficacia di ABBV-8E12 nel rallentare l’atrofia cerebrale regionale e/o globale in soggetti affetti da paralisi sopranucleare progressiva come misurato dalla RMN volumetrica. |
