E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of study 3133K1-3002-WW is to evaluate the long term safety and tolerability of intravenously administered bapineuzumab in subjects with Alzheimer Disease (AD) based on adverse events, scheduled vital signs, electrocardiogram parameters, clinical laboratory tests, brain MRI scans, physical and neurological examinations, and infusion site assessment. In addition, the studies will be continuously monitored by an independent safety monitoring committee. |
|
E.2.2 | Secondary objectives of the trial |
In order to explore the long-term effect of bapineuzumab in subjects with AD, exploratory efficacy measures in study 3002 will include Alzheimer’s Disease Assessment Scale - Cognitive Subscale (ADAS-Cog), Disability Assessment for Dementia (DAD), Mini Mental State Examination (MMSE), Neuropsychiatric Inventory (NPI) and health outcome assessments [Dependence Scale (DS), Resource Utilization in Dementia, version 2.4 (RUD Lite v2.4), and Health Utilities Index (HUI)].
Biomarker objectives: please refer to section E.2.3 / E.2.3.1.

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Substudies are incorporated into the main protocol, and so do not have a separate title/date/version. Four substudies are included: a cerebrospinal fluid (CSF) substudy, a volumetric MRI substudy, a PET substudy and a biochemical characterization substudy.
Objectives: To evaluate the effect of IV administered bapineuzumab on biomarkers in subsets of subjects with AD: • Amyloid (Pittsburgh Compound B (PIB)) and fluorodeoxyglucose (FDG) positron emission tomography (PET) imaging. • Brain volumetrics by magnetic resonance imaging (MRI). • Aβ in cerebrospinal fluid (CSF) and plasma, total tau and phospho-tau levels in CSF. • Biochemical characterization of circulating bapineuzumab antibody will also be conducted in a subset of subjects, using immunoaffinity chromatography from patient sera.

E.3 | Principal inclusion criteria |
1. Signed and dated written informed consent obtained from the subject or the subject’s legally acceptable representative (if applicable) in accordance with the local regulations. The subject’s caregiver must also consent to participate in the study. 2. Subject has completed all 6 infusions planned in protocol 3133K1-3000; or, if the subject was required to temporarily suspend investigational product (e.g., due to vasogenic edema), he/she continued with required visits, has completed all study visits through the week 78 visit and his/her current status indicates that he/she resumed or is eligible to resume investigational product. NOTE: Subjects who developed vasogenic edema during study 3133K1-3000 may be considered for study 3133K1-3002 participation if the abnormality is resolved and the subject met criteria to resume investigational product. Medical monitor approval is required prior to enrollment. 3. Brain MRI scan from week 71 of study 3133K1-3000 is available for local radiology and central radiology evaluation and remains consistent with the diagnosis of AD. 4. MMSE score ≥10 at screening (week 78 of 3133K1-3000). 5. Continues to live at home or community dwelling with appropriate caregiver capable of accompanying the subject on all clinic visits and visiting with the subject at least 5 days per week, on average for the duration of the study. 6. In the opinion of the principal investigator, the subject and the caregiver will be compliant, and likely to participate in all scheduled evaluations.

E.4 | Principal exclusion criteria |
1. Any medical or psychiatric contraindication or clinically significant abnormality on physical, neurological, laboratory, vital signs or electrocardiogram (ECG) examination (e.g., atrial fibrillation) that precludes continued or initiation of treatment with bapineuzumab, participation in the study or evaluation of the subject’s response. 2. Brain MRI scan from study 3133K1-3000 week 71 visit indicative of any significant abnormality, including but not limited to multiple microhemorrhages (two or more), history or evidence of a single prior hemorrhage > 1 cm3, multiple lacunar infarct (two or more) or evidence of a single prior infarct > 1 cm3, evidence of a cerebral contusion, encephalomalacia, aneurysms, vascular malformations, subdural hematoma, or space occupying lesions (e.g., arachnoid cysts or brain tumors such as meningioma). 3. Use of any experimental medications, other than bapineuzumab, within the last 60 days prior to screening. 4. Current use of herbal preparations containing ginkgo biloba, or use of anticoagulants. NOTE: Platelet anti-aggregants (e.g., the use of aspirin 325 mg/day or less, clopidogrel bisulfate, dipyridamole except for stroke) are allowed.
