Outcome Measures

Primary Outcomes (3)

  • Incidence of Treatment-emergent Adverse Events (AEs) by Severity

    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)

    Baseline up to 24 months

  • Number of Participants With Brain Abnormalities in Magnetic Resonance Imaging (MRI) Data

    Number of participants with brain abnormalities in MRI data that are either consistent or not consistent with AD, as determined by investigator.

    Baseline up to 24 months

  • Number of Participants With Abnormalities in Neurological Examination

    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.

    Baseline up to 24 months

Secondary Outcomes (2)

  • Anti-a-beta IgG Titer at Specified Visits

    Baseline up to 24 months

  • Anti-a-beta IgM Titer at Specified Visits

    Baseline up to 24 months

Other Outcomes (4)

  • 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 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 Mean Changes in Neuropsychological Test Battery (NTB) Score From Baseline at Week 12, 26, 36, 52, 78 and 104.

    Baseline up to 24 months
