Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Change From Baseline to Month 18 in Cognitive Subscale of the Alzheimer´s Disease Assessment Scale (ADAS-Cog)
Délai: Baseline to 9 Months (actual time frame)
The ADAS-Cog is a validated psychometric instrument that evaluates memory (word recall, word recognition), attention, reasoning (following commands), language (naming, comprehension), orientation, ideational praxis (placing letter in envelope) and constructional praxis (copying geometric designs). This test was administered by experienced raters certified by Alzheimer's Disease Cooperative Study (ADCS) at each site. Scores on the ADAS-Cog range from 0-70 with higher scores indicating greater impairment; hence increases from baseline reflect potential cognitive deterioration.
Baseline to 9 Months (actual time frame)
Change From Baseline to Month 18 in Alzheimer´s Disease Cooperative Study (ADCS)-Activities of Daily Living (ADL) Inventory
Délai: Baseline to 9 Months (actual time frame)
The ADCS-ADL scale is a validated tool to assess instrumental and basic activities of daily living based on a 23 item structured interview of the caregiver or qualified study partner. Scores on the ADCS-ADL range from 0-78 with lower scores indicating greater impairment; hence decreases from baseline reflect potential functional deterioration.
Baseline to 9 Months (actual time frame)

Description de la mesure
Délai
ADCS-Clinical Global Impression of Change (CGIC) at 18 Months
Délai: Baseline to 9 Months (actual time frame)
The ADCS-CGIC is a validated categorical measure of change in a participant's global clinical status between baseline and follow-up visits, based on interview of the participant and the caregiver by a skilled and experienced clinician who was blinded to treatment assignment. The ADCS-CGIC score is based on a 7-point Likert scale, ranging from 1 (marked improvement) to 7 (marked worsening).
Baseline to 9 Months (actual time frame)
Change From Baseline to Month 18 in Neuropsychiatric Inventory (NPI)
Délai: Baseline to 9 Months (actual time frame)
The NPI is a validated instrument used to assess behavioral psychopathology in AD; it evaluates the frequency and severity of 10 neuropsychiatric features including delusions, hallucinations, dysphoria, anxiety, agitation/aggression, euphoria, disinhibition, irritability/lability, apathy, aberrant motor activity, sleep and night-time behavior change, and appetite and eating change. The NPI total score ranged 0-144, with higher scores indicating greater impairment.
Baseline to 9 Months (actual time frame)
Change From Baseline to Month 18 in Volumetric Magnetic Resonance Imaging (MRI) Parameters: Rate of Whole Brain Atrophy and Ventricular Enlargement
Délai: Baseline to 9 Months (actual time frame)
Baseline to 9 Months (actual time frame)
Change From Baseline to Month 18 in Logsdon Quality of Life in Alzheimer´s Disease (QOL-AD)
Délai: Baseline to 9 Months (actual time frame)
The QOL AD is a validated, 13-item instrument developed specifically for individuals with dementia. The assessment rates the participant´s quality of life for physical, emotional, interpersonal, and environmental domains. The QOL-AD total score ranged 13-52, with lower scores associated with a lower quality of life.
Baseline to 9 Months (actual time frame)
Change From Baseline to Month 18 in Impact of Alzheimer´s Disease on Caregiver Questionnaire (IADCQ)
Délai: Baseline to 9 Months (actual time frame)
The IADCQ is a 12-item validated questionnaire that has been developed to measure the emotional, physical, and social impact of care giving on AD caregivers. Higher scores on the IADCQ are associated with a higher impact. IADCQ total score range: 0 (no impact) - 48 (greatest impact). Each item can be scored either 0 (Not at all), 1 (A little), 2 (Somewhat), 3 (A lot), or 4 (Extremely). As this is a 12-item scale, the minimum possible score is 0 and the maximum possible score is 4x12 = 48.
