Inclusion and exclusion criteria.

Inclusion criteria
1. Written informed consent was obtained according to local requirements for obtaining consent in patients with mild AD. An additional written informed consent was obtained from all patients who participated in the PET substudy.
2. Male and female patients <85 years of age. In addition, patients had to be ≥50 years of age to participate in the PET substudy.
3. Female patients without childbearing potential (post-menopausal or surgically sterilized).
• If sterilized, female patients were surgically sterilized ≥6 months prior to screening. Surgical sterilization procedures were supported with clinical documentation made available to the Novartis Monitor and noted in the Relevant Medical History/Current Medical Conditions section of the electronic case report form.
OR:
• Postmenopausal women had no regular menstrual bleeding for ≥1 year prior to inclusion as documented in the patient’s records.
4. Diagnosis of dementia of the Alzheimer’s type according to the DSM-IV criteria.
5. Patients who satisfied the criteria for a clinical diagnosis of probable AD established by a
Work Group of the NINCDS-ADRDA.
6. Mild AD was confirmed by a MMSE score of 20–26 (both inclusive) at screening, and either untreated or on stable dose of cholinesterase inhibitor and/or other AD treatment over the last 4 weeks prior to the clinical assessments.
7. Sufficient education to be able to read, write, and communicate effectively during the premorbid state (e.g., completion of ≥6 years of regular schooling or sustained employment).
8. Cooperative, willing to complete all aspects and attend all visits of the study including lumbar puncture/CSF samplings (primarily for safety reasons), and capable of doing so, either alone or with the aid of a responsible caregiver.
9. Residing with someone in the community throughout the study or, if living alone, who had daily contact with a primary caregiver.
10. Primary caregiver was present and willing to assent in writing to accept responsibility for assessing the condition of the patient throughout the study, and for providing input to safety and tolerability assessments in accordance with all protocol requirements.
Exclusion criteria
Exclusion criteria related to CNS
1. Any medical or neurological condition, other than AD, that contributed significantly to the
patient’s dementia (e.g., abnormal thyroid function tests, Vitamin B12 or folate deficiency, post-traumatic conditions, Huntington’s disease, Parkinson’s disease, Lyme’s disease, syphilis, HIV, dementia), including any CSF and/or brain MRI findings at screening.
2. History in the past 2 years or current diagnosis of CNS inflammation as indicated by:
• either MRI findings indicative of meningoencephalitis or another concurrent disease
(according to central reader evaluation at screening and clinical judgment);
• or signs of inflammation in CSF as defined by clinical judgment. In most cases, in a
CSF sample not contaminated by blood, this was shown by >5 leukocytes/μL).
3. Evidence of vascular dementia or other cerebrovascular disease, assessed to be of clinical significance by either investigator or MRI central reader, defined as any of the following:
• ≥1 large infarct (>2cm) or ≥2 lacunar infarcts (<2cm); or
• confluent white matter lesions, considered likely to contribute to patients’ dementia; or
• intracranial aneurysms or hemorrhages, except for up to one cerebral microhemorrhage, defined as a focal T2* hypointensity <1 cm or a superficial hemosiderosis; or
NB. If an MRI machine with field strength >1.5 T was used, up to two microhemorrhages were acceptable.
• Hachinski score of >4 at screening, or any transitory ischemic attack or unexplained loss of consciousness in the past year.
4. DSM-IV diagnosis of major depression and/or any other DSM-IV Axis 1 diagnosis that may have interfered with the evaluation of the patient’s response to study medication, including other primary neurodegenerative dementia, schizophrenia, or bipolar disorder.
5. Current diagnosis of an active, uncontrolled seizure disorder.
Exclusion criteria related to other medical conditions
6. Any advanced, severe, progressive, or unstable disease that could interfere with the safety, tolerability, and pharmacodynamics assessments and/or with the antibody titer response in the study or put the patient at special risk (e.g., indication for anticoagulant therapies, Hepatitis B or C, HIV).
7. History or current diagnosis of an active autoimmune disease (e.g., psoriasis, rheumatoid
arthritis, Crohn’s disease, systemic lupus erythematosus, Type I diabetes mellitus,
Hashimoto thyroiditis).
8. Evidence of systemic inflammation as shown by e.g., an elevated C-reactive protein above normal range at screening or fever (i.e., axillary body temperature ≥38°C
[100.4°F]) before dosing on the day of first injection, as measured at the site).
NB. In case of positive findings at screening that were considered to be due to a known
transient condition (e.g., common cold, urinary tract infection), the randomization could be postponed until findings have normalized.
9. Coronary heart disease as shown by:
• history of myocardial infarction or coronary stent placement within the preceding year,
or
• current diagnosis of unstable angina pectoris or atherosclerotic coronary artery disease of clinical significance.
10. Symptomatic heart failure fulfilling the criteria of New York Heart Association Category>II or known left ventricular dysfunction with left ventricular ejection fraction <45%, or any other severe or unstable cardiovascular disease.
11. Vital signs outside of the following ranges at screening and baseline evaluations (as
measured after ≥3 minutes resting in the supine position):
• systolic blood pressure: 95–165 mmHg
• diastolic blood pressure: 50–95 mmHg
12. A QTc value ≥500 msec on the screening electrocardiogram assessed by the central electrocardiogram reader using either Bazett or Fridericia formula, whichever was the highest.
13. History of malignancy of any organ system, treated or untreated, within the past 5 years
whether or not there was evidence of local recurrence or metastases. However, localized
tumors not requiring systemic chemo- or radiotherapy were permitted.

i.e., drugs that require monitoring of a specific organ (e.g., clozapine, tamoxifen)
• parenteral immunoglobulin preparation, blood products, and/or plasma derivates
• anticoagulants (e.g., coumadin) or antiplatelet agents (e.g., clopidogrel). However,

in the body).
21. Donation or loss of >400 mL of blood within 8 weeks prior to first injection.
22. Contraindication to lumbar puncture, e.g., platelet count <100000 /μL or any other finding.
23. Any disability that could have prevented the patient from completing all study
requirements (e.g., blindness, deafness, severe language difficulty).

NB: MMRM for the change or percentage change from baseline in PET included factors for effects of responder group, the corresponding baseline value, visit, and interaction terms treatment group*visit and baseline value*visit. The model for change from baseline in vMRI was also adjusted for whole brain volume normalized on intracranial volume and age and performed for all regions of interest (ROIs).

Abbreviations: FAS, full analysis set; vMRI, volumetric magnetic resonance imaging; SD, standard deviation.
