1.  Primary:   Change From Baseline in the Alzheimer's Disease Assessment Scale - Japan Cognitive Subscale (ADAS-J Cog)   [ Time Frame: Baseline and 24 weeks ]

Measure Type Primary
Measure Title Change From Baseline in the Alzheimer's Disease Assessment Scale - Japan Cognitive Subscale (ADAS-J Cog)
Measure Description ADAS-J cog is the Japanese version of the cognitive function subscale of the Alzheimer's disease assessment scale (ADAS). This scale is used to detect changes in cognitive function in individuals with Alzheimer disease on the basis of three domains: memory, language and behavior. The minimum score is zero (0) and means well cognitive function. The maximum total score is 70 points, and the larger the score, the more severe the degree of impairment.
Time Frame Baseline and 24 weeks  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.

3.  Secondary:   Change From Baseline in the Disability Assessment for Dementia (DAD)   [ Time Frame: Baseline and 24 weeks ]

Measure Type Secondary
Measure Title Change From Baseline in the Disability Assessment for Dementia (DAD)
Measure Description Each of the 40 item of the DAD is scored as 1 point= Yes, 0 point= No, or non applicable= N/A. A total score (minimum=0; maximum=40) is the sum of points for each questions converted out 100. Items rated as Not Applicable (N/A) are not considered for the total score. The final score is a percentage that gives an appreciation of global function in activity of daily life (ADL). Higher scores represent less disability in ADL while lower scores indicate more dysfunction.
