Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of Treatment-emergent Adverse Events (AEs) by Severity | Baseline up to 24 months | Number of participants who experienced mild, moderate, or severe AEs (mild = does not interfere with subject's usual function; moderate = interferes to some extent with subject's usual function; severe = interferes significantly with subject's usual function) |
| Number of Participants With Abnormalities in Neurological Examination | Baseline up to 24 months | Number of participants with abnormalities in neurological examinations as determined by the investigators. Neurological examinations included Mental Status, Speech, Cranial Nerves (including pupil equality and reactivity), Visual field, Sensory, Motor, Coordination, Gait, Primitive reflexes, Tendon reflexes and Romberg. |
| Number of Participants With Brain Abnormalities in Magnetic Resonance Imaging (MRI) Data | Baseline up to 24 months | Number of participants with brain abnormalities in MRI data that are either consistent or not consistent with AD, as determined by investigator. |

| Anti-a-beta IgG Titer at Specified Visits | Baseline up to 24 months | Geometric mean of anti-a-beta IgG titer from pre-study through Week 104 |

Other
| Measure | Time frame | Description |
|---|---|---|
| The Mean Changes in Disability Assessment for Dementia (DAD) Score From Baseline at Week 12, 26, 36, 52, 78 and 104. | Baseline up to 24 months | The DAD is administered through an interview with the caregiver and measures instrumental and basic activities of daily living. A total score is obtained by adding the rating for each question and converting this total score out of 100. Higher scores represent less disability in ADL while lower scores indicate more dysfunction. |
| The Mean Changes in Mini-Mental State Examination (MMSE) Score From Baseline at Week 4, 8, 12, 16, 26, 30, 36, 40, 52, 78 and 104. | Baseline up to 24 months | The MMSE is a brief, structured examination of cognitive function. It has a total score of 30 points (0-30), and any score equal to or lower than 26 points indicates cognitive impairment. |
| The Mean Changes in Neuropsychological Test Battery (NTB) Score From Baseline at Week 12, 26, 36, 52, 78 and 104. | Baseline up to 24 months | The NTB is a composite of nine widely used neuropsychological tests that assess immediate and delayed recall of verbal and visual information, attention, verbal fluency and executive function. The cognitive tests included in the NTB are the Wechsler Memory Scale (WMS) Visual-Paired Associates (immediate and delayed), WMSVerbal Paired Associates (immediate and delayed), Rey Auditory Verbal Learning Test (immediate and delayed), WMS-Digit Span, Controlled Word Association Test, and Category Fluency Test. The NTB z-score is used for analysis. The z-score for each component is calculated through the following formula: z = (y\_visit - y\_base)/SD\_base, where y\_visit is a value at a particular time point and y\_base is the average test score, and SD\_base is the SD based on all participants' observed baseline scores in the study. |
| The Mean Changes in Alzheimer's Disease Assessment Scale-Cognitive Behavior (ADAS-Cog) Score From Baseline at Week 12, 26, 36, 52, 78 and 104. | Baseline up to 24 months | The ADAS-Cog is a 12-item,objective measure of cognitive function, consisting of 1) Word Recall, 2) Naming Objects and Fingers, 3) Following Commands, 4) Constructional Praxis, 5) Ideational Praxis, 6) Orientation, 7) Word Recognition, 8) Recall of Test Instructions, 9) Spoken Language Ability, 10) Word-Finding Difficulty, 11) Comprehension of Spoken Language and 12) Concentration/Distractibility. For this stuy, the ADAS-Cog total score is derived by summing the individual scores from items 1 to 11. Total score ranges from 0 to 70 points, with higher scores indicating a greater degree of impairment. |

The ADAS-Cog is a 12-item,objective measure of cognitive function, consisting of 1) Word Recall, 2) Naming Objects and Fingers, 3) Following Commands, 4) Constructional Praxis, 5) Ideational Praxis, 6) Orientation, 7) Word Recognition, 8) Recall of Test Instructions, 9) Spoken Language Ability, 10) Word-Finding Difficulty, 11) Comprehension of Spoken Language and 12) Concentration/Distractibility. For this stuy, the ADAS-Cog total score is derived by summing the individual scores from items 1 to 11. Total score ranges from 0 to 70 points, with higher scores indicating a greater degree of impairment.
Time frame: Baseline up to 24 months
Population: Efficacy analyses were performed on the modified intent-to-treat (mITT) population. The mITT population included all of the randomly assigned participants who took at least one dose of study medication, and had the baseline and at least one post baseline evaluation of the key efficacy variable (ADAS-Cog).

The Mean Changes in Disability Assessment for Dementia (DAD) Score From Baseline at Week 12, 26, 36, 52, 78 and 104.
The DAD is administered through an interview with the caregiver and measures instrumental and basic activities of daily living. A total score is obtained by adding the rating for each question and converting this total score out of 100. Higher scores represent less disability in ADL while lower scores indicate more dysfunction.
Time frame: Baseline up to 24 months
Population: Efficacy analyses were performed on the modified intent-to-treat (mITT) population. The mITT population included all of the randomly assigned participants who took at least one dose of study medication, and had the baseline and at least one post baseline evaluation of the key efficacy variable (ADAS-Cog).

The Mean Changes in Mini-Mental State Examination (MMSE) Score From Baseline at Week 4, 8, 12, 16, 26, 30, 36, 40, 52, 78 and 104.
The MMSE is a brief, structured examination of cognitive function. It has a total score of 30 points (0-30), and any score equal to or lower than 26 points indicates cognitive impairment.
Time frame: Baseline up to 24 months
Population: Efficacy analyses were performed on the modified intent-to-treat (mITT) population. The mITT population included all of the randomly assigned participants who took at least one dose of study medication, and had the baseline and at least one post baseline evaluation of the key efficacy variable (ADAS-Cog).

The Mean Changes in Neuropsychological Test Battery (NTB) Score From Baseline at Week 12, 26, 36, 52, 78 and 104.
The NTB is a composite of nine widely used neuropsychological tests that assess immediate and delayed recall of verbal and visual information, attention, verbal fluency and executive function. The cognitive tests included in the NTB are the Wechsler Memory Scale (WMS) Visual-Paired Associates (immediate and delayed), WMSVerbal Paired Associates (immediate and delayed), Rey Auditory Verbal Learning Test (immediate and delayed), WMS-Digit Span, Controlled Word Association Test, and Category Fluency Test. The NTB z-score is used for analysis. The z-score for each component is calculated through the following formula: z = (y\_visit - y\_base)/SD\_base, where y\_visit is a value at a particular time point and y\_base is the average test score, and SD\_base is the SD based on all participants' observed baseline scores in the study.
Time frame: Baseline up to 24 months
Population: Efficacy analyses were performed on the modified intent-to-treat (mITT) population. The mITT population included all of the randomly assigned participants who took at least one dose of study medication, and had the baseline and at least one post baseline evaluation of the key efficacy variable (ADAS-Cog).
