Outcomes

Primary Outcome Measures

Change in Total Score of Standardized Mini-Mental State Examination (sMMSE); Full Analysis Set
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.

Secondary Outcome Measures

Disability Assessment for Dementia Change From Baseline; Activities of Daily Living (ADL) Domain.
The ADL domain includes 17 yes/no questions on four items (hygiene, dressing, continence, eating). Score equals number of questions answered yes multiplied by 100 divided by number of questions answered. Change: Mean ADL score at observation minus mean ADL score at baseline.
Disability Assessment for Dementia Change From Baseline; Instrumental ADL (IADL) Domain.
IADL domain consists of 23 yes-no questions on 6 items (meal preparation, telephoning, going out, finance & correspondence, medications, leisure & housework. Change: Mean IADL score at observation minus mean IADL score at baseline. Total IADL score = number of questions answered yes multiplied by 100 divided by total number of questions answered
Disability Assessment for Dementia (DAD) Change From Baseline Total Score; Full Analysis Set (FAS)
DAD total score equals total number of questions answered yes multiplied by 100 divided by total number of questions answered.
Free-hand Drawing Test (CLOX 1) Change From Baseline; Full Analysis Set (FAS)
The ability to draw a clock free-hand. Scored on a scale from 1 to 15; lower scores indicate higher impairment. Change: Mean CLOX 1 score at observation minus mean CLOX score at baseline.
Copied Clock Drawing Test (CLOX 2) Change From Baseline; Full Analysis Set (FAS)
The ability to copy a drawing of a clock. Scored on a scale from 1 to 15; lower scores indicate higher impairment. Change: Mean CLOX 2 score at observation minus mean CLOX 2 score at baseline.
CLOX Differential Score Change From Baseline; Full Analysis Set (FAS)
CLOX differential score equals the difference between the score for CLOX 2 and the score for CLOX 1, values range from 15 to 0, with 0 indicating perfect executive function, and a worsening with the increasing score.
Phonectic Fluency Total Score From Baseline; Full Analysis Set (FAS)
The number of words a particpant can generate in 1 minute.
Neuropsychiatric Inventory Questionnaire (NPI-Q) Score Change From Baseline; Full Analysis Set (FAS)
NPI-Q measures severity of behavioural manifestations of dementia & the level of distress each symptom gives the main caregiver, 1 (mild), 3 (severe), 0 if symptom absent, NPI-Q also measures the caregiver distress associated with each symptom,0(no distress)to 5(very severe), total score equals sum of individual item scores & ranges from 0 to 36
Neuropsychiatric Inventory Questionnaire Distress (NPI-Q-D) Score Change From Baseline; Full Analysis Set (FAS)
The total NPI-Q-D score is equal to the sum of all indiviudal symptom distress scale scores with a range of 0 to 60
Clinical Global Impressions Severity Score (CGI-S) Clinical Global Impressions Severity Score Improvement(CGI-I)Change From Baseline, Full Analysis Set (FAS)
Scale measures subject's clinical condition at baseline for severity (CGI-S) & for improvement from baseline (CGI-I). At baseline subject rated on numerical scale, 1 (not at all ill) to 7 (most extremely ill). At follow up subject rated on 7 point Likert scale from 1(very much improved) to 7(very much worse) & 4 indicates no change from baseline
Clinical Global Impressions Severity (CGI-S)
Scale measures subject's clinical condition at baseline for severity (CGI-S) subject rated on numerical scale, 1 (not at all ill) to 7 (most extremely ill).
Clinical Global Impressions Improvement (CGI-I)
Scale measures subject's clinical condition for improvement from baseline (CGI-I)subject rated on 7 point Likert scale from 1(very much improved) to 7(very much worse) & 4 indicates no change from baseline
Clinical Global Impressions Improvement (CGI-I) Dichotomized Response
Scale measures subject's (CGI-I) rated on categorial 7 point Likert scale 1 (very much improved) to 7 (very much worse) with 4 indicating no change from baseline. A dichotomized variable was created: responder = CGI-I score of 4 or less; non-responder = CGI-I score of 5 or more

5. Study Description

Brief Summary
To document effectiveness, safety, and tolerability of donepezil in patients with mixed AD/VaD, and to further document the effectiveness, safety, and tolerability of donepezil in patients with VaD. The effects of donepezil on executive functioning, behavior, general cognition, ADLs and global functioning will be assessed.
Detailed Description
The trial was terminated on October 15, 2007 due to difficulties in recruiting the subjects. There were no safety or efficacy concerns regarding the study medication in the decision to terminate the trial.
