  • Change From Baseline in Volumetric Magnetic Resonance Imaging (vMRI) - Brain Boundary Shift Integral (BBSI) and Ventricular Boundary Shift Integral (VBSI) [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
    BBSI and VBSI were calculated based on the voxel-wise difference between co-registered baseline and follow-up scans. Least squares (LS) mean value was controlled for baseline value and visit.
  • Change From Baseline in Volumetric Magnetic Resonance Imaging (vMRI) - Hippocampus Volume Average Percent (%) Change (Chg) [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
    Automated hippocampal volumetry was performed using the Learning Embeddings for Atlas Propagation (LEAP) algorithm. LS mean value was controlled for baseline value and visit.
  • Change From Baseline in Resting State Functional Magnetic Resonance Imaging (rsfMRI) [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
    Distributed functional connectivity in selected brain networks was calculated from the rsfMRI scans. Values were derived from low-frequency (0.01-0.1 hertz [Hz]) temporal correlations between different regions over the approximately 6-minute rsfMRI time series scan. Distributed measures of functional connectivity were calculated as the mean Pearson correlation between the average low-frequency time courses in predefined sets of regions of interest (ROI) within the default mode network (DMN), salience network (SN) and sensorimotor networks (SMN). LS mean value was controlled for baseline value and visit.
  • Change From Baseline in Diffusion Tensor Imaging (DTI) Using Fractional Anisotropy (FA) [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
    DTI scans used FA to measure water diffusion directionality in selected white matter (WM) tracts. ROI: Corpus collosum (CC), internal capsule (IC), posterior cingulum bundle (PCB), temporal white matter (TWM), uncinate fasciculus (UF), superior longitudinal fasciculus (SLF). LS mean value was controlled for baseline value and visit.
  • Change From Baseline in Diffusion Tensor Imaging (DTI) Using Mean Diffusivity (MD) [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
    DTI scans used MD to measure the overall magnitude of water diffusion in selected WM tracts, without specific regard to directionality. ROI: CC, IC, PCB, TWM, UF, SLF. LS mean value was controlled for baseline value and visit.
  • Change from baseline up to 9 months in volumetric magnetic resonance imaging (vMRI) [ Time Frame: Time zero equals baseline, up to 9 months ]
  • Change from baseline up to 9 months in resting state functional magnetic resonance imaging (rsfMRI) [ Time Frame: Time zero equals baseline, up to 9 months ]
  • Change from baseline up to 9 months in diffusion tensor imaging (DTI) [ Time Frame: Time zero equals baseline, up to 9 months ]

  • Baseline Brain Amyloid Load Using Positron Emission Tomography (PET) and Florbetapir [ Time Frame: Baseline ]
    Composite summary standardized uptake value ratio (SUVR) normalized to mean whole cerebellum. Regions used for composite summary were posterior cingulum, anterior cingulum, parietal cortex, lateral temporal cortex and frontal cortex.
  • Number of Participants With Vasogenic Edema on MRI Scan at a Field Strength of 3 Tesla (3T) [ Time Frame: Baseline ]
  • Number of Participants With Microhemorrhage on MRI Scan at a Field Strength of 3T [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
  • Change From Baseline in the Mini Mental State Examination (MMSE) Total Score [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
    The 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). Total score ranges from 0 to 30; lower score indicates greater disease severity. LS mean value was controlled for baseline value and visit.
  • Change From Baseline in the Alzheimer's Disease Assessment Scale Extended Cognitive Subscale (ADAS-Cog14) Total Score [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
    The ADAS-Cog14 is the ADAS-Cog11 augmented with delayed free recall, digit cancellation, and maze completion measures. A score of 0 to 10 for delayed free recall and a conversion code of 0 to 5 for digit cancellation and maze completion provide total score ranges for this extended ADAS-Cog14 of 0 to 90. Higher scores indicate greater disease severity. LS mean value was controlled for baseline value and visit.
  • Change From Baseline in the Clinical Dementia Rating (CDR) Total Score [ Time Frame: Baseline, 6 Mos; Baseline, 12 Mos ]
    The CDR 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 ranges from 0 to 18. Higher scores indicate greater disease severity. LS mean value was controlled for baseline value and visit.
  • Baseline Brain Amyloid Load Using Positron Emission Tomography (PET) and Florbetapir [ Time Frame: Time zero equals baseline ]
  • Number of participants with vasogenic edema on MRI scan at a field strength of 3T [ Time Frame: Time zero equals baseline, up to 9 months ]
  • Number of Participants With Microhemorrhage on MRI Scan at a Field Strength of 3T [ Time Frame: Time zero equals baseline, up to 9 months ]

A Non-drug Methods Study in Participants With Alzheimer's Disease
An Exploratory Study of Brain Imaging Biomarkers in Patients With Alzheimer's Pathology Receiving Standard of Care
This study will investigate the volume, function and composition of the brain using magnetic resonance imaging (MRI) and positron emission tomography (PET) scanning technology in participants with memory complaints or early signs of Alzheimer's pathology.
After trial initiation, the protocol was amended to extend the single observation time period (6 to 9 months) to two time points (6 and 12 months), and to focus on prodromal AD (Mini-Mental State Examination [MMSE] 23-30 inclusive, Free and Cued Selective Reminding Test [FCSRT] less than or equal to [≤] 24 for free recall or ≤ 44 for total recall). Participants enrolled under the original protocol were allowed to continue in the extension study if they so desired, and if they met the new inclusion criteria. Due to the number of participants that completed the extended trial, no sub-group analysis was performed based on which amendment the participants entered under.
