Primary Outcome Measures:
  • Nature and incidence of adverse events [ Time Frame: From the enrollment visit until the last study follow-up visit. The measure will be taken at each scheduled study visit and in between visits , if any adverse events occur. ]

Secondary Outcome Measures:
  • To evaluate any effects PK of AZD1446 as an add-on treatment to donepezil on the PK of donepezil [ Time Frame: Twice during the study: at Visit 2 and Visit 10. ]
  • To characterize the PK of AZD1446 as an add-on treatment to donepezil in AD patients [ Time Frame: Twice during the study: at Visit 8 and Visit 10. ]
  • To explore the effects of 3 dose regimens of AZD1446 compared to placebo as an add-on treatment to donepezil on changes in global functioning using ADCS-CGIC [ Time Frame: Baseline assessment at Visit 2 and a follow-up assessment at Visit 10 ]
