You may not qualify if:

• Any cause of dementia not due to Alzheimer's disease :
• other central nervous conditions causing progressive deficits in memory and cognition, e.g. cerebrovascular disease, Parkinson's disease, Huntington's disease, brain tumor…
• systemic conditions known to cause dementia, e.g., hypothyroidism, untreated vitamin B12 or folic acid deficiency, niacin deficiency, neurosyphilis, HIV infection…
• substance-induced conditions
• Alzheimer disease with delusions or delirium
• Treatment with any registered or putative cognitive enhancer or disease modifier other than donepezil, galantamine, rivastigmine or memantine
• Uncontrolled depression at screening
• Evidence of psychosis and/or use of antipsychotic drugs at screening, or history of significant psychotic disorder or hospitalization for psychiatric disorders
• Active current bacterial, viral (including hepatitis B and C, HIV, EBV, CMV, herpes zoster, herpes simplex), fungal, mycobacterium, protozoan, or other infection.
• History of infection requiring hospitalization or treatment with antibiotics within 2 weeks of screening
• Inadequate organ function, defined as follows : total bilirubin ≥ 1.5 x ULN, SGOT and SGPT ≥ 2.5 x UNL, creatinine clearance calculated by Crocroft method \< 35 ml/mn, ANC ≤ 2500, platelets ≤ 100 000 at baseline
• Treatment with any investigational agent within 4 weeks of screening,
• Men and their partner refusing to use 2 methods of medically acceptable forms of contraception during the study.
• History of poor compliance or history of drug/alcohol abuse, or excessive alcohol beverage consumption that would interfere with the ability to comply with the study protocol, or current or past psychiatric disease that might interfere with the ability to comply with the study protocol or give informed consent
• Any condition that, in the investigator's opinion, could be detrimental to subjects participating in this study as life expectancy \< 1 year, or any clinically important deviations from normal clinical laboratory values or concurrent medical events.
