  • Change From Baseline to Week 78 in Neuropsychological Test Battery (NTB) Z-score (Full Analysis Set; FAS) [ Time Frame: Baseline and 78 weeks ] [ Designated as safety issue: No ]
    The NTB assessment is comprised of 9 instruments that measure cognition and executive function. Three of these tests measure immediate memory, next three measure delayed memory, and remaining three assess executive function. The total score is a weighted mean of the nine tests, referred to as the Z-score. Typically, scores range from -3 and 3, with lower scores suggesting greater cognitive impairment.
  • Additional Analysis of Primary Outcome Measure: Change From Baseline to Week 78 in Neuropsychological Test Battery (NTB) Z-score (Per Protocol Set; PPS) [ Time Frame: Baseline and 78 weeks ] [ Designated as safety issue: No ]
    The NTB assessment is comprised of 9 instruments that measure cognition and executive function. Three of these tests measure immediate memory, next three measure delayed memory, and remaining three assess executive function. The total score is a weighted mean of the nine tests, referred to as the Z-score. Typically, scores range from -3 and 3, with lower scores suggesting greater cognitive impairment.
  • Change From Baseline to Week 78 in Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) Score (Full Analysis Set; FAS) [ Time Frame: Baseline and 78 weeks ] [ Designated as safety issue: No ]
    The ADCS-ADL is a 23-item scale that measures a subject's functional abilities as assessed by the subject's caregiver. This scale ranges from 0 to 78, with lower scores suggesting greater functional impairment.
  • Additional Analysis of Primary Outcome Measure: Change From Baseline to Week 78 in Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) Score (Per Protocol Set; PPS) [ Time Frame: Baseline and 78 weeks ] [ Designated as safety issue: No ]
    The ADCS-ADL is a 23-item scale that measures a subject's functional abilities as assessed by the subject's caregiver. This scale ranges from 0 to 78, with lower scores suggesting greater functional impairment.

  • Change in Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-Cog) Score From Baseline to Week 78 (Full Analysis Set; FAS) [ Time Frame: Baseline and 78 weeks ] [ Designated as safety issue: No ]
    The ADAS-Cog primarily measures cognitive ability. The version used in this study was comprised of 12 items with scores ranging from 0 to 75. Higher scores suggest greater cognitive impairment.
  • Change in Clinical Dementia Rating - Sum of Boxes (CDR-SB) Score From Baseline to Week 78 (Full Analysis Set; FAS) [ Time Frame: Baseline and 78 weeks ] [ Designated as safety issue: No ]
    The CDR-SB consists of 6 items; 3 measuring cognitive ability and 3 measuring functional ability. The score for each of the six items range from 0 to 3; hence the total score is between 0 and 18. Higher scores suggest greater cognitive impairment.
  • Change in Neuropsychiatric Inventory (NPI) Score From Baseline to Week 78 (Full Analysis Set; FAS) [ Time Frame: Baseline and 78 weeks ] [ Designated as safety issue: No ]
    The NPI is used to obtain information on the presence of severity of neuropsychological symptoms, and was specifically designed for use in Alzheimer's disease subjects. The scale consists of 12 items with each item having outcomes from 0 to 12; hence the total score ranges from 0 to 144. Higher scores suggest greater psychiatric impairment.

ELND005 in Patients With Mild to Moderate Alzheimer's Disease
A Randomized, Double-Blind, Placebo-Controlled, Dose-Ranging, Safety and Efficacy Study of Oral ELND005 (AZD-103) in Alzheimer's Disease

The purpose of this study is to evaluate the dose-related safety and efficacy of multiple oral dosages of ELND005 as treatment for Alzheimer's disease (AD).

ELND005 (formerly known as AZD-103), scyllo-inositol, is being investigated as an orally administered treatment for AD. ELND005 may prevent or inhibit the build up of amyloid protein in the brains of AD patients.

This is a randomized, double-blind, placebo-controlled, dose-ranging, safety and efficacy study of oral ELND005 in male and female participants aged 50-85 years with mild to moderate AD. Approximately 340 patients will be enrolled into the study at approximately 65 study sites. Patients will be randomized to receive either ELND005 or placebo. Each patient's participation will last approximately 18 months.
