E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary efficacy variable: Mean change in Dyskinesias Rating Scale (DRS) during `on' time from baseline (Study 016) to endpoint (last visit in Study 018). |
Variabile primaria: Cambiamenti medi delle discinesie in confronto a placebo durante la fase `on` (Dyskinesias Rating Scale) dalla baseline (studio 016) all`endpoint (ultima visita dello studio 018). |
|
E.2.2 | Secondary objectives of the trial |
Secondary efficacy variables: Change in ON time (ON + ON minor dyskinesia) as compared to baseline. • Diary Responder Rate at 12 months (primary), and 18, and 24 months (secondary) on the ITT and mITT populations and on the subset of those patients who completed the 2-year treatment period: o Improvement in ON time + ON time with minor dyskinesia, with no increase in troublesome dyskinesia with respect to baseline, o Lack of worsening (`¤ 30 min) in ON time + ON time with minor dyskinesia, with no increase in troublesome dyskinesia with respect to baseline. • UPDRS IV total score (primary) and, if significant, items 32-35 and 32-34 taken individually and as subgroups (secondary), change from baseline. • Time to develop troublesome dyskinesia (> 30-minute increase of troublesome dyskinesia compared to baseline). • Time to develop any (minor and/or troublesome) dyskinesia (> 30-minute increase of dyskinesia compared to baseline). See protocol page 3. |
- Superiorita` significativa di safinamide rispetto a placebo in:- Modificazioni della sfera cognitiva (cognitive test battery)- Modificazioni delle attivita` della vita quotidiana (ADLs) durante la fase `on` in confronto al placebo (UPDRS Parte II)- Mantenimento dell`effetto nei `responders` (miglioramento > 20% rispetto alla ADL basale)- Riduzione del dosaggio della levodopa- Riduzione del tempo giornaliero totale di `off` rilevato dal diario- Modificazione dei sintomi motori (UPDRS ParteIII)- CGI modificazioni dal basale- modificazione del punteggio medio durante lo studio- CGI gravita` di malattia- modificazioni del punteggio basale vs finale |
