Primary Outcome Measures :
- Part 1 : Change from Baseline in the Alzheimer's Disease Assessment Scale - Cognitive subscale (ADAS-cog14) at Month 6 [ Time Frame: 6 months ]The ADAS-cog14 scoring range is from 0 to 90, with higher scores indicating greater cognitive impairment
- Part 2: Change from Baseline in the ADAS-cog14 at Month 18 [ Time Frame: 18 months ]The ADAS-cog14 scoring range is from 0 to 90, with higher scores indicating greater cognitive impairment
- Part 2: Change from Baseline in Clinical Dementia Rating Scale-Sum of Boxes (CDR-sb) at Month 18 [ Time Frame: 18 months ]Sum of box scores range from 0 to 18 with higher scores indicating greater cognitive impairment.
Secondary Outcome Measures :
- Part 1: Change from Baseline in the Clinical Dementia Rating Scale-Sum of Boxes (CDR-sb) at Month 6 [ Time Frame: 6 months ]Sum of box scores range from 0 to 18 with higher scores indicating greater cognitive impairment.
- Part 1: Change from Baseline in the Functional Activities Questionnaire (FAQ) at Month 6 [ Time Frame: 6 months ]The total FAQ score ranges from 0 to 30, with higher scores indicating greater functional loss.
- Part 1: Change from Baseline in the Amsterdam-Instrumental Activities of Daily Living (Amsterdam-IADL) at Month 6 [ Time Frame: 6 months ]The A-IADL total score is calculated using an item response theory method of scoring and lower scores indicate greater functional impairment
- Part 1: Change from Baseline in estimated glomerular filtration rate (eGFR) at Month 6 [ Time Frame: 6 months ]
- Part 2: Responder status at Months 6, 12, and 18 based on the ADAS-cog14 [ Time Frame: 6, 12, 18 months ]The ADAS-cog14 scoring range is from 0 to 90, with higher scores indicating greater cognitive impairment
- Part 2: Change from Baseline in FAQ score at Month 18 [ Time Frame: 18 months ]The total FAQ score ranges from 0 to 30, with higher scores indicating greater functional loss.
- Part 2: Change from Baseline in Amsterdam-IADL score at Month 18 [ Time Frame: 18 months ]
- Part 2: Change from Baseline in MMSE score at Month 18 [ Time Frame: 18 months ]MMSE scores range from 0-30 with lower scores indicating greater cognitive impairment.
- Part 2: Change from Baseline in eGFR at Month 18 [ Time Frame: 18 months ]
- Part 2: Change from Baseline in whole brain volume at Month 18 [ Time Frame: 18 months ]
Other Outcome Measures:
- Proportions of subjects with treatment-emergent adverse events [ Time Frame: 3,6 months (Part 1) ; 3,6,9,12,15,18 months (Part 2) ]
- Proportions of subjects with treatment-emergent abnormal clinical laboratory values [ Time Frame: 3,6 months (Part 1) ; 3,6,9,12,15,18 months (Part 2) ]
- Proportions of subjects with abnormal values or changes in vital signs measures of potential clinical concern [ Time Frame: 3,6 months (Part 1) ; 3,6,9,12,15,18 months (Part 2) ]
- Proportions of subjects with treatment-emergent 12-lead ECG results of potential clinical concern [ Time Frame: 3,6 months (Part 1) ; 3,6,9,12,15,18 months (Part 2) ]
- Part 2: Change from Baseline at Month 18 for Neuropsychiatric Inventory [ Time Frame: 18 months ]Scores range from 0-144 with higher scores indicating a greater presence of neuropsychiatric symptoms.
- Part 2: Change from Baseline at Month 18 Dementia Quality of Life (DEMQOL-proxy) [ Time Frame: 18 months ]Higher scores indicate better health related quality of life.
- Part 2: Change from Baseline in plasma concentrations of Aβ species at Month 18 [ Time Frame: 18 months ]
- Part 2: Change from Baseline in brain MRI (hippocampal, ventricular) volumetric measures at Month 18 [ Time Frame: 18 months ]
