  Purpose
This study will evaluate the safety and tolerability of bapineuzumab when administered by subcutaneous injection. The study is open only to subjects who participated in the preceding double-blind study (3133L1-2203 US). Subjects will receive weekly injections of bapineuzumab for 3 years (156 doses). One dosage level will be included: 5 mg/week. All subjects will receive active treatment (bapineuzumab) and no subjects will receive placebo.

Primary Outcome Measures:
  • Number of Participants Reporting Clinically Significant Magnetic Resonance Imaging (MRI) Findings [ Time Frame: Week 13, 26, 39, 52, 65, 78, 91, 104, 117, 130, 143, 156, Any visit ]
    A brain Magnetic Resonance Imaging (MRI) was obtained from all participants at Week 13 and quarterly thereafter. Participants were to meet the following criteria: screening brain MRI scan is consistent with the diagnosis of Alzheimer's Disease. Screening diagnosis of probable Alzheimer's disease according to National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS/ADRDA) criteria. Clinically significant MRIs were identified by the investigator. The number of participants with clinically significant MRIs are tabulated by visit and treatment group.


Secondary Outcome Measures:
  • Pharmacokinetic Parameters Including Maximal Serum Drug Concentration, Time to Maximal Serum Drug Concentration, and Terminal Half-life of Elimination [ Time Frame: 36 months ]
