Study Endpoints

Primary Endpoints

Antibody Titer (Serum Anti-Aβ1-42 Free IgG) - Mean Absolute Value
Values at baseline (week 0) and week 50 are reported

All subjects who received at least 1 dose of the study treatment of either ACI-24 300 μg, ACI-24 1000 μg or placebo are considered. The measure is expressed in Arbitrary Units per mL (AU/mL). AU/mL in a sample is obtained by back-calculation towards the standard curve.

Secondary Endpoints

Amyloid Beta 1-40 in Blood - Mean Absolute Value
Values at baseline (week 0) and week 50 are reported
CANTAB - MOT Latency Score
Values at baseline (week 0) and week 50 are reported
CANTAB - PAL First Attempt Memory Score
