Eligibility
Key inclusion criteria
* Ages =55 and =85 years
* Informed consent form (ICF) signed by the subject or legally acceptable representative before any study-specific procedures for the subject are performed and an ICF signed by the support person/caregiver before any study-specific procedures for the support person/caregiver are performed
* Clinical diagnosis of dementia due to probable AD consistent with criteria established by a workgroup of the National Institute on Aging and the Alzheimer's Disease Association
* Clinical decline within 12 months before screening and onset of symptoms at least 12 months or longer before screening, which may include any documented cognition, functional, or other objective assessment or the clinical judgment of the investigator or the subject's referring physician that the subject has experienced a clinical decline within the last 12 months
* Magnetic resonance imaging (MRI) or computed tomography (CT) scan performed within 12 months before screening, with findings consistent with the diagnosis of dementia due to AD without any other clinically significant comorbid pathologies. If an MRI or CT scan is unavailable or occurred greater than 12 months before screening, this assessment should be completed and the findings confirmed before the subject enters the run-in period (Day -14) (copy of the report will be available at the study site)
* Mini-Mental State Examination (MMSE) score =14 and =24 at screening and confirmed on Day 1 prior to randomization (fluctuations of ±2 points are acceptable on Day 1/baseline)
* Clinical Dementia Rating Global score (CDR-GS) =1 (at least mild dementia) at screening and confirmed on Day 1 prior to randomization
* Modified Hachinski Ischemic Scale (mHIS) score =4 at screening
* Fertile, sexually active subjects (men and women) must use an effective method of contraception during the study. Female subjects and the female partner of male subjects must be surgically sterile (hysterectomy or bilateral tubal ligation), postmenopausal for at least 1-year, or willing to practice adequate methods of contraception if of childbearing potential (defined as consistent use of combined effective methods of contraception [including at least 1 barrier method])
* Reliable and capable support person/caregiver, who if not living in the same household, interacts with the subject approximately 4 times per week and will be available to attend clinic visits in person when possible
* Subject living at home, senior residential setting, or an institutional setting without the need for continuous (ie, 24-hour) nursing care
* General health status acceptable for participation in a 26-week study
* Fluency (oral and written) in the language in which the standardized tests will be administered
* Receiving a stable dose of an acetylcholinesterase inhibitor (AChEI) (donepezil, rivastigmine or galantamine) for at least 3 months (90 days) before screening and with continuous dosing for at least 6 months OR not presently receiving an AChEI (at least 30 days before screening), but with a history of previous AChEI treatment (subjects receiving donepezil 23 mg currently or within 3 months before screening are ineligible)
Minimum age
55 Years
Maximum age
85 Years
Sex
Both males and females
Can healthy volunteers participate?

* Renal insufficiency (serum creatinine >2.0 mg/dL)
* Malignant tumor within 3 years before screening (except squamous and basal cell carcinoma or cervical carcinoma in situ or localized prostate cancer)
* Female subjects who are pregnant, nursing, or planning to become pregnant during the study

* History of myocardial infarction or unstable angina within 6 months before screening
* History of more than 1 myocardial infarction within 5 years before screening
* Clinically significant (in the judgment of the investigator) cardiac arrhythmia (including atrial fibrillation), cardiomyopathy, or cardiac conduction defect (subjects with a pacemaker are acceptable)
* Symptomatic hypotension or hypertension (supine diastolic blood pressure >95 mmHg) (in the judgment of the investigator)
* Clinically significant abnormality on screening or baseline electrocardiogram (ECG), including but not necessarily limited to a confirmed corrected QT interval (QTc) value =450 msec for males or =470 msec for females. In subjects with a QRS value >120msec, those with a QTc value <500 msec may be eligible following discussion with the Medical Monitor.
* Stroke within 18 months before screening, or history of a stroke concomitant with onset of dementia
* History of brain tumor, subdural hematoma, or other clinically significant (in the judgment of the investigator) space-occupying lesion on CT or MRI
* Head trauma with clinically significant (in the judgment of the investigator) loss of consciousness within 12 months before screening or concurrent with the onset of dementia
* Onset of dementia secondary (in the judgment of the investigator) to cardiac arrest, surgery with general anesthesia, or resuscitation
* Specific degenerative central nervous system (CNS) disease diagnosis other than AD (eg, Huntington's disease, Creutzfeld-Jacob disease, Down's syndrome, Fronto-Temporal Dementia, Parkinson's disease)
* Subjects with no history of prior treatment with an AChEI (donepezil, rivastigmine, or galantamine)
* Memantine currently or within 30 days before screening
* Antipsychotics; low doses (in the judgment of the investigator, except clozapine) are allowed only if given for sleep disturbances, agitation and/or aggression, and only if the subject has received a stable dose for at least 3 months before screening (but not within 8 hours before any cognitive test)
* Tricyclic antidepressants and monoamine oxidase inhibitors; all other antidepressants are allowed only if the subject has received a stable dose for at least 3 months before screening

* Nicotine therapy (including the patch), varenicline (Chantix), or similar therapeutic agent within 30 days before screening
* Clinically significant urine drug screen or serum alcohol test result in the judgment of the investigator
* History of ischemic colitis or ischemic enterocolitis
