What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Treatment Emergent Adverse Events (AEs) by Severity
Time Frame: Baseline up to 24 months
Number of mild, moderate, and 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)
Baseline up to 24 months
Number of Participants With Brain Abnormalities in Magnetic Resonance Imaging (MRI) Data
Time Frame: 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 radiologists.
Baseline up to 24 months
Number of Participants With Abnormalities in Neurological Examination
Time Frame: Baseline of the preceding studies through 24 months of this study
Number of participants with abnormalities in neurological examinations as determined by the investigators. Neurological examinations included Mental Status, Speech, Cranial Nerve Function, Cranial Nerve II, Sensory Function, Motor Function, Coordination, Gait and Station, Reflexes and Deep Tendon Reflexes.
Baseline of the preceding studies through 24 months of this study

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Anti-A-beta IgG (Immunoglobulin G) Titer at Specified Visits
Time Frame: Baseline of preceding studies to month 24 of this study (Week 210)
Geometric mean of anti-a-beta IgG titer from baseline of the preceding studies through the end of this study
Baseline of preceding studies to month 24 of this study (Week 210)
Anti-A-beta IgM (Immunoglobulin M) Titer at Specified Visits
Time Frame: Baseline of preceding studies to month 24 of this study (Week 210)
Geotmetric mean of anti-a-beta IgM titer from baseline of the preceding studies through the end of this study
Baseline of preceding studies to month 24 of this study (Week 210)
The Mean Changes in Alzheimer's Disease Assessment Scale-Cognitive Behavior (ADAS-Cog) Score From Baseline at Week 26, 52, 78 and 104.
Time Frame: 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 study, the ADAS-Cog total score is derived by summing the individual scores from items 1 to 11, with higher scores indicating a greater degree of impairment. The total score ranges from 0 (no impairment) to 70 (worst impairment).
Baseline up to 24 Months
The Mean Changes in Disability Assessment for Dementia (DAD) Score From Baseline at Week 26, 52,78 and 104.
Time Frame: 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.
Baseline up to 24 Months
The Mean Changes in Neuropsychological Test Battery (NTB) Score From Baseline at Week 26, 52, 78 and 104.
Time Frame: 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), WMS-Verbal 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.
Baseline up to 24 Months
The Mean Changes in Mini-Mental State Examination (MMSE) Score From Baseline at Week 12, 26, 36, 52, 66, 78, 91 and 104.
Time Frame: Baseline up to 24 Months
The MMSE is a brief, structured examination of cognitive function. It has a total score of 30 points, and any score equal to or lower than 26 points indicates cognitive impairment.
Baseline up to 24 Months
