Percentage of Participants With Treatment-emergent AEs or Serious Adverse Events (SAEs) [ Time Frame: approximately 110 weeks, including a 6-week screening period, 52 weeks of dosing and 54 weeks for follow-up after the last dose ]
An AE was any untoward, undesired, or unplanned clinical event in the form of signs, symptoms, disease, or laboratory or physiologic observations occurring in a person given study drug or in a sponsor's clinical study. The event did not need to be causally related to the study drug or the clinical studies. A treatment emergent AE was defined as an event that emerged during the treatment period that was absent before treatment, or worsened during the treatment period relative to the pretreatment state. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Adverse events, other safety assessments, tolerability, and immunogenicity.

  • Geometric Mean Titers (GMTs) of Anti-A-beta Immunoglobulin G (IgG) Total Using an Enzyme-linked Immunosorbent Assay (ELISA) at Weeks 2, 4, 6, 8, 10, 14, 16, 24, 28, 30, 40, 50, 54, 56, 66, 78, 91, and 104 [ Time Frame: Baseline, Week 2, 4, 6, 8, 10, 14, 16, 24, 28, 30, 40, 50, 54, 56, 66, 78, 91, and 104 ]
    The lower limit of quantification (LLOQ) was 100 U/mL and when the assay result was below LLOQ (100 U/mL), 50 U/mL was imputed for IgG.
  • GMTs of Anti-A-beta Immunoglobulin M (IgM) Using ELISA at Weeks 2, 4, 6, 8, 10, 14, 16, 24, 28, 30, 40, 50, 54, 56, 66, 78, 91, and 104 [ Time Frame: Baseline, Week 2, 4, 6, 8, 10, 14, 16, 24, 28, 30, 40, 50, 54, 56, 66, 78, 91, and 104 ]
    The LLOQ was 50 U/mL and when the assay result was below LLOQ (50 U/mL), 25 U/mL was imputed for IgM.
  • Change From Baseline GMTs of Anti-A-beta IgG Subtypes Using ELISA at Visits Where an IgG Total Response is Measurable (at Weeks 2, 4, 6, 8, 10, 14, 16, 24, 28, 30, 40, 50, 54, 56, 66, 78, 91, and 104 if Applicable) [ Time Frame: Baseline, Week 2, 4, 6, 8, 10, 14, 16, 24, 28, 30, 40, 50, 54, 56, 66, 78, 91, and 104 ]
    IgG subtypes were not assessed
