1.Primary Outcome
Title Change From Baseline in Neuropsychological Test Battery in Total Z-score After 12-week Treatment.
Hide Description Neuropsychological Test Battery (NTB) response, defined as change from baseline in total z-score after 12 weeks of treatment. The NTB consists of 9 validated components. Raw scores on each of the 9 NTB tests were converted to z-scores using the baseline means and standard deviations (SDs) for each test. The resultant z-scores were averaged to obtain a total z-score, incorporating all 9 NTB tests. The NTB Z-score indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean at baseline. Negative numbers indicate values lower than baseline and positive numbers indicate values higher than baseline. Least Squares Mean is actually an adjusted mean change from baseline.

Title Change From Baseline in Alzheimer's Disease Cooperative Study/Activities of Daily Living (ADCS-ADL) Total Score After 12-week Treatment
Hide Description Alzheimer's Disease Cooperative Study/Activities of Daily Living (ADCS-ADL) is a rating scale used to assess basic and instrumental activities of daily living. In the full version of the scale, 23 items are rated by the investigator using information supplied by the caregiver. Each item has a score range varying from 0-3 to 0-5. The sum score can range from 0 to 78. Higher scores indicate better function. Least Squares Mean is actually an adjusted mean change from baseline.

4.Secondary Outcome
Title Change From Baseline in Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) Total Score After 12-week Treatment
Hide Description The CDR-SB is obtained through semi-structured interviews of patients and informants, and cognitive functioning was rated in 6 domains of functioning: memory, orientation, judgment and problem solving, community affairs, home and hobbies and personal care. Each domain was rated on a 5-point scale of functioning as follows: 0-no impairment; 0.5-questionable impairment; 1-mild impairment; 2-moderate impairment and 3-severe impairment. Only personal care was scored on a 4-point scale without a 0.5 rating available. The higher the score, the greater the severity of dementia. Least Squares Mean is actually an adjusted mean change from baseline.

Title Change From Baseline in Alzheimer's Disease Assessment Scale-cognitive Subscale (ADAS-cog11) Total Score After 12-week Treatment
Hide Description Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog11) is an 11-item cognitive subscale that objectively measures memory, language, orientation, and praxis with a total score range of 0 to 70. The greater the dysfunction, the greater the score. Least Squares Mean is actually an adjusted mean change from baseline.
