- Change in Cognition [ Time Frame: Baseline and Week 24 ]
Change from baseline to Week 24 in Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) total score.
The Alzheimer's Disease Assessment Scale - Cognitive subscale (ADAS-cog) is a 11-item neuropsychological test that assess the severity of cognitive impairment. The items determine the patient's orientation, memory, language, and praxis. Total score of the 11 items range from 0 to 70 (lower score indicates lower cognitive impairment).
- Change in Global Impression [ Time Frame: Baseline and Week 24 ]
Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change (ADCS-CGIC) score at Week 24.
The Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change is a semi-structured interview to assess clinically relevant changes in patients with AD. The items determine cognition, behavior, social and daily functioning. Severity at baseline is rated on a 7-point scale from 1 (normal, not ill at all) to 7 (among the most extremely ill patients). The clinically relevant change from baseline is rated on a 7-point scale from 1 (marked improvement) to 7 (marked worsening).
- Change in Daily Functioning [ Time Frame: Baseline and Week 24 ]
Change from baseline to Week 24 in Alzheimer's Disease Cooperative Study - Activities of Daily Living Inventory (ADCS-ADL23) total score.
The Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL23) is a 23-item clinician-rated inventory to assess activities of daily living (conducted with a caregiver or informant). Each item comprises a series of hierarchical sub-questions, ranging from the highest level of independent performance to a complete loss for each activity. Total score of the 23 items ranges from 0 to 78 (higher score indicates lower disability).
- Change in Behavioural Disturbance [ Time Frame: Baseline and Week 24 ]
Change from baseline to Week 24 in Neuropsychiatric Inventory (NPI) total score
The Neuropsychiatric Inventory is a 12-item structured interview with a caregiver to assess behavioural disturbances. The NPI comprises 10 behavioural and 2 neurovegetative items. Each item consists of a screening question and several sub-questions that are rated no (not present) or yes (present). Each item is then rated for frequency (a 4-point scale from 1 [occasionally] to 4 [very frequent]) and severity (a 3-point scale from 1 [mild] to 3 [marked]). The total NPI score is the frequency ratings multiplied by the severity ratings and ranges from 0 to 144 (higher score indicates worse outcome).
- Change in Individual Behavioural Disturbance Items [ Time Frame: Baseline and Week 24 ]
Change in single NPI item scores at Week 24.
The Neuropsychiatric Inventory is a 12-item structured interview with a caregiver to assess behavioural disturbances. The NPI comprises 10 behavioural and 2 neurovegetative items. Each item consists of a screening question and several sub-questions that are rated no (not present) or yes (present). Each item is then rated for frequency (a 4-point scale from 1 [occasionally] to 4 [very frequent]) and severity (a 3-point scale from 1 [mild] to 3 [marked]). Total score for each single NPI item ranges from 0-12 (frequency multiplied by severity), where higher scores represent worse outcome.
- Change in NPI Anxiety Item Score in Patients With an NPI Anxiety Item Score of at Least 2 at Baseline [ Time Frame: Baseline and Week 24 ]
Change from baseline to Week 24 in NPI anxiety item score in patients with an NPI anxiety item score of at least 2 at baseline
The Neuropsychiatric Inventory is a 12-item structured interview with a caregiver to assess behavioural disturbances. The NPI comprises 10 behavioural and 2 neurovegetative items. Each item consists of a screening question and several sub-questions that are rated no (not present) or yes (present). Each item is then rated for frequency (a 4-point scale from 1 [occasionally] to 4 [very frequent]) and severity (a 3-point scale from 1 [mild] to 3 [marked]). The total score for the NPI anxiety item ranges from 0-12 (frequency multiplied by severity), where a higher score represents a worse outcome.
- Clinical Improvement [ Time Frame: Week 24 ]Clinical response at Week 24 (based on pre-specified ADAS-cog, ADCS-ADL23, and ADCS-CGIC changes [change in ADAS-cog below or equal to -4, change in ADCS-ADL23 at least 0, and ADCS-CGIC below or equal to 4])
- Clinical Worsening [ Time Frame: Week 24 ]Clinical worsening at Week 24 (Based on pre-specified ADAS-cog, ADCS-ADL23, and ADCS-CGIC changes [change in ADAS-cog above or equal to 4, change in ADCS-ADL23 below 0, and ADCS-CGIC above 4])
- Change in Cognitive Aspects of Mental Function [ Time Frame: Baseline and Week 24 ]
Change from baseline to Week 24 in Mini Mental State Examination (MMSE).
The Mini Mental State Examination (MMSE) is an 11-item test to assess the cognitive aspects of mental function. The subtests assess orientation, memory, attention, language, and visual construction. The scores for each item is dichotomous (1 = response is correct, 0 = response is incorrect). Total score of the 11 items ranges from 0 to 30 (higher score indicates lower deficit).
- Change in Health-related Quality of Life (EQ-5D) Utility Score [ Time Frame: Baseline and Week 24 ]
Change from baseline to Week 24 in EuroQol 5-dimensional (EQ-5D) utility score
The EQ-5D is a patient-reported assessment that measures the patient's well-being. It consists of an utility score based on 5 descriptive items (mobility, self-care, usual activities, pain/discomfort, and depression/anxiety) and a Visual Analogue Scale (VAS). Each descriptive item is rated on a 3-point index ranging from 1 (no problems) to 3 (extreme problems) that is used for calculating a single summary index (from 0 to 1). A higher EQ-5D score indicates a worse outcome.
- Change in Health-related Quality of Life (EQ-5D VAS) [ Time Frame: Baseline and Week 24 ]
Change from baseline to Week 24 in EQ-5D Visual Analogue Scale (EQ-5D VAS).
The EQ-5D is a patient-reported assessment that measures the patient's well-being. It consists of an utility score based on 5 descriptive items (mobility, self-care, usual activities, pain/discomfort, and depression/anxiety) and a Visual Analogue Scale (VAS). The VAS ranges from 0 (worst imaginable health state) to 100 (best imaginable health state).
