  • Number of Participants with categorical scores on the Columbia Suicide Severity Rating Scale (C-SSRS) [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]
    C-SSRS assessed whether participant experienced following: completed suicide (1), suicide attempt (2) (response of "Yes" on "actual attempt"), preparatory acts toward imminent suicidal behavior (3)("Yes" on "preparatory acts or behavior"), suicidal ideation (4) ("Yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent), any suicidal behavior or ideation, self-injurious behavior (7)("Yes" on "Has subject engaged in non-suicidal self-injurious behavior").
  • Electrocardiogram (ECG) [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]
    Measure incidence, frequency and severity of ECG abnormal findings
  • MRI [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]
    Measure incidence, frequency and severity of MRI abnormal findings
Adverse events, clinical laboratory results, vital signs, physical and neurological examinations, ECGs, Columbia Suicide Severity Rating Scale (C-SSRS), magnetic resonance imaging (MRI) of the brain. [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]

Open Label Extension Study Evaluating Safety and Tolerability of AAB-003 (PF-05236812) in Subject With Mild to Moderate Alzheimer's Disease
A Multicenter, Open-label Extension, Multiple-dose, Parallel Group Study to Investigate the Long-term Safety and Tolerability of AAB-003 (PF-05236812) Administered Intravenously in Subjects With Mild to Moderate Alzheimer's Disease Previously Treated With AAB-003 or Placebo in Protocol B2601001

This is a study to evaluate the safety and tolerability of multiple doses of AAB-003 (PF-05236812) in patients with mild to moderate Alzheimer's Disease. Patients who complete study B2601001 may participate in this trial and receive AAB-003 (PF-05236812). Each patient's participation will last approximately 52 weeks.
