Trial Outcomes & Findings for Vaspect Study - An Open-Label Trial Of Donepezil in Vascular and Mixed Dementia (NCT NCT00174382)

NCT ID: NCT00174382

Last Updated: 2015-03-24

Results Overview

Change from baseline in sMMSE total score. Change: mean total score at observation minus mean total score at baseline. Total score is derived by adding all subscores and ranges from 0 to 30; a higher score indicates a better cognitive state.

Donepezil
Subjects received open-label donepezil treatment with 5 mg administered per os (orally; PO)quaque die (every day; QD) for 6 weeks. Donepezil was increased to 10 mg QD (the maximum dose)at the Week-6 visit for an additional planned 18 weeks.

PRIMARY outcome

Timeframe: Baseline, week 12, week 24

Population: Full Analysis Set (FAS):all subjects who received at least one dose donepezil and who have baseline and at least one post-baseline assessment of efficacy and LOCF = Last Observation Carried Forward. N=137; Weeks 12, 24 n=124, 114

Change from baseline in sMMSE total score. Change: mean total score at observation minus mean total score at baseline. Total score is derived by adding all subscores and ranges from 0 to 30; a higher score indicates a better cognitive state.
