Inclusion Criteria

1. Male or female subject with a clinical diagnosis of probable Alzheimer's disease in
accordance with Diagnostic and Statistical Manual of Mental Disorders, Fourth
Edition (DSM-IV) criteria and National Institute of Neurological and
Communicative Diseases and Stroke/Alzheimer’s Disease and Related Disorders
Association (NINCDS-ADRDA) criteria
2. Subject has a documented history of symptoms of AD for at least 6 months prior to
entry into the study
3. Subject has MMSE score 12-24 inclusive at Screening and a baseline MMSE score
10-26 inclusive. The MMSE score at baseline must be within ± 3 points of the
Screening value
4. Hachinski Ischaemia score = 4 at Screening
5. Age = 50 to = 85 years
6. A female subject must be:
a. Of non-childbearing potential (i.e., any female who is post-menopausal [ > 1 year
without menstrual period in the absence of hormone replacement therapy1] or
surgically sterile; or,
b. If pre-menopausal or menopausal for 1 year or less, must have a negative pregnancy test and must not be lactating at the Screening and Baseline Visits and agrees to satisfy one of the requirements listed in Appendix 4
7. Subject has the ability to comply with procedures for cognitive and other testing in
the opinion of the investigator
8. Subject lives with (or has substantial periods of contact with) a regular caregiver who is willing to attend all visits, oversee the subject's compliance with protocol specified procedures and study medication, and report on subject's status
Note: A non-cohabiting caregiver must spend sufficient time with the subject so that
in the opinion of the Investigator, the caregiver can reliably assess cognitive
function, activities and behaviour, and report on the subject’s compliance and health.
GSK should be consulted if adequacy of a caregiver situation is in doubt. However,
as guidance, the ability for a caregiver to meet his/her expected responsibilities for
this study would normally be possible when the caregiver spends no less than 10
hours per week with the subject, divided over multiple days
9. Subject has provided full written informed consent prior to the performance of any
protocol-specified procedure; or if unable to provide informed consent due to
cognitive status, subject has provided assent and full written informed consent on
behalf of the subject has been provided by a legally acceptable representative
10. Caregiver has provided full written informed consent on his/her own behalf prior to the performance of any protocol-specified procedure

Exclusion Criteria

1. Diagnosis of possible, probable or definite vascular dementia in accordance with
National Institute of Neurological Disorders and Stroke-Association Internationale
pour la Recherche l’Enseignement en Neurosciences (NINDS-AIREN) criteria
2. History and/or evidence (CT or MRI scan performed within the past 12 months or at Screening) of any other central nervous system (CNS) disorder that could be
interpreted as a cause of dementia (in the opinion of the investigator): e.g.
cerebrovascular disease (stroke, haemorrhage), structural or developmental
abnormality, epilepsy, infectious, degenerative or inflammatory/demyelinating CNS
conditions, Parkinson’s disease2
3. Focal findings on the neurological exam (excluding changes attributable to AD or
peripheral injury)
4. Evidence of the following disorders: current vitamin B12 deficiency, positive
syphilis serology (unless neurosyphilis was ruled out) or active thyroid dysfunction
(particularly suggestive of hypothyroidism), including abnormally high or low serum
levels of thyroid stimulating hormone (TSH), where this is thought to be the cause
of, or to contribute to the severity of, the subject’s dementia
(Note: testing is required for each parameter only when no result is available from
previous 12 months)
