Study Summary

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).

Primary Outcome

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.
