Willingness to comply with the requirements of the protocol and ability to comply with testing and infusion regimen, including adequate corrected visual acuity and hearing ability
For at least 12 weeks prior to screening, on stable doses of AD medication(s) approved by local regulatory authorities. Subjects must not be on two acetylcholinesterase inhibitors concurrently.
Venous access for repeated infusion and phlebotomy

For women of childbearing potential, the subject must have a negative pregnancy test at screening and must agree to employ adequate contraceptive measures (eg, birth control pills/patches, intrauterine device, or diaphragm or condom [for male partner] with spermicidal jelly or foam) throughout the course of the study
For subjects with a coronary artery stent, the subject must receive documented medical clearance from an interventional cardiologist stating that the subject is not at increased risk for stent occlusion with immunoglobulin treatment
For subjects with an endovascular stent, the subject must receive documented medical clearance from a vascular surgeon stating that the subject is not at increased risk for thromboembolic events with immunoglobulin treatment

Main Exclusion Criteria:
