The monoclonal antibody that preferentially targets Aß oligomers failed to meet either of its coprimary end points—despite favorable results over the placebo group—in individuals who were unimpaired but at risk for AD.

Using several large-scale cohorts, findings showed that cumulative incidence of Alzheimer disease grows faster with age in R145C variant carriers compared with noncarriers, contradicting prior research results.
