- Change From Baseline in Alzheimer´s Disease Assessment Scale- Cognitive Subscale (ADAS-Cog14) Score [ Time Frame: Baseline, 24 Months ]ADAS-Cog14 is ADAS-Cog11 augmented with orientation, verbal memory, language, praxis, delayed free recall, digit cancellation, and maze-completion measures. The ADAS-Cog14 scale ranges from 0 to 90. Higher scores indicate greater disease severity.
- Change From Baseline on Alzheimer´s Disease Cooperative Study-Activities of Daily Living Scale for Mild Cognitive Impairment (ADCS-MCI-ADL) [ Time Frame: Baseline, 24 Months ]The ADCS-MCI-ADL is a functional evaluation scale for MCI patients, based on information provided by an informant that describes the performance of participants in several ADLs. Total score ranges from 0 to 69; lower score indicates greater disease severity.
- Change From Baseline on the Mini Mental Status Examination (MMSE) [ Time Frame: Baseline, 24 Months ]MMSE is a brief screening instrument used to assess cognitive function (orientation, memory, attention, ability to name objects, follow verbal/written commands, write a sentence, and copy figures) in elderly participants.Total score ranges from 0 to 30; lower score indicates greater disease severity.
- Change From Baseline on the Montreal Cognitive Assessment (MoCA) [ Time Frame: Baseline, 24 Months ]The MoCA will be used as the global cognitive screening instrument. It will also be administered in the clinical trial at baseline and the final visits of each phase as a secondary outcome measure of global cognition. Scores on the MoCA range from 0-30 with 26-30 indicating normal global cognition.
- Change From Baseline on the Functional Activities Questionnaire (FAQ) [ Time Frame: Baseline, 24 Months ]FAQ is a 10-item, caregiver-based questionnaire and was administered to the study partner who was asked to rate the participant's ability to perform a variety of activities ranging from Writing checks, Assembling tax records, shopping, playing games, food preparation, traveling, keeping appointments, Traveling out of neighborhood, keeping track of current events and understanding media. FAQ total score was calculated by adding the scores from each of the 10 items. Each activity is rated on a scale from 0 to 3 (Never did and would have difficulty now = 1; Never did [the activity] but could do now = 0; Normal = 0; Has difficulty but does by self = 1; Requires assistance = 2; Dependent = 3). The maximum FAQ total score is 30, with higher scores indicating greater impairment.
- Change From Baseline on the Neuropsychiatric Inventory (NPI) [ Time Frame: Baseline, 24 Months ]The NPI is a tool for assessing psychopathology in participants with dementia and other neurologic disorders. Information is obtained from a caregiver familiar with the participant's behavior. The score ranges from 12 to 144, with higher scores indicating greater disease severity.
- Change From Baseline on the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) [ Time Frame: Baseline, 24 Months ]CDR-SB is a semi-structured interview of participants and their caregivers. Participant's cognitive status is rated across 6 domains of functioning, including memory, orientation, judgment/problem solving, community affairs, home/hobbies, and personal care. Severity score assigned for each of 6 domains; total score (SB) ranges from 0 to 18. Higher scores indicate greater disease severity.
- Change From Baseline on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) [ Time Frame: Baseline, 24 Months ]RBANS is a brief neurocognitive battery with four alternate forms, measuring immediate and delayed memory, attention, language, and visuospatial/constructional skills.
- Change From Baseline on the Free and Cued Selective Reminding Test (FCSRT) [ Time Frame: Baseline, 24 Months ]The FCSRT is a neuropsychological test of memory under conditions that control attention and cognitive processing in order to obtain an assessment of memory unconfounded by normal age-related changes in cognition.
- Change From Baseline on the Resource Utilization in Dementia-Lite (RUD-Lite) [ Time Frame: Baseline, 24 Months ]RUD-Lite assesses the healthcare resource utilization of participants and their caregivers to determine the level of formal and informal care attributable to Alzheimer's Disease (AD). Information on both caregivers (caregiving time, work status) and participants (accommodation and healthcare resource utilization) is collected from the baseline and follow-up interviews.
- Change From Baseline on the EuroQol 5-Dimensional Health-Related Quality of Life Scale (EQ-5D) [ Time Frame: Baseline, 24 Months ]EQ-5D (proxy version) measures mobility, self-care, usual activities, pain/discomfort, anxiety/depression; each has 3 severity levels (no, some, severe problems) coded to a 1-digit number (1-3). Digits are combined into 5-digit number describing health state. Visual analogue scale (VAS) assesses caregiver's impression of participant's overall health state; scores range: 0 to 100. Lower scores indicate greater disease severity.
- Change From Baseline on the Quality of Life in Alzheimer's Disease Scale (QoL-AD) [ Time Frame: Baseline, 24 Months ]QoL for AD assess participant rates mood, relationships, memory, finances, physical condition, and overall QoL assessment. Each of 13 items rated on a 4-point scale. Sum of items=total score (range: 13-52). Higher scores=greater QoL.
- Change From Baseline in Concentration of Plasma Amyloid-β Peptide (Aβ) and Plasma Solanezumab [ Time Frame: Baseline, 24 Months ]Concentration of amino acid peptide known as Aβ 1-42 in plasma.
- Change From Baseline in Volumetric Magnetic Resonance Imaging (vMRI) [ Time Frame: Baseline, 24 Months ]MRI will be used to assess the effect of treatment on rate of whole brain volume.
- Change From Baseline in Florbetapir Positron Emission Tomography (PET) Standardized Uptake Value Ratio (SUVr) [ Time Frame: Baseline, 24 Months ]Florbetapir F18 PET used to assess the treatment effect in brain amyloid plaque deposition from baseline through 18 months as measured by florbetapir F18 PET Standardized Uptake Uptake Value ratio.
- Change From Baseline in Concentration of Cerebrospinal Fluid (CSF) Aβ and CSF Tau Proteins [ Time Frame: Baseline, 24 Months ]Changes in CSF parameters, including total and free Aβ1-40 and Aβ1-42 species and total tau and P-tau181 peptides, will be assessed.
- Change From Baseline in Neocortical Tau Deposits Using 18F-AV-1451 PET [ Time Frame: Baseline, 24 Months ]Biomarker change will be analyzed to provide biomarker-based evidence that solanezumab affects the underlying disease pathology.
