NCT02353598

Brief Summary

This randomized, placebo-controlled, double-blind, parallel-arm study will evaluate the safety and tolerability of at least two dose levels of intravenous (IV) crenezumab in 24-72 participants with mild to moderate Alzheimer disease (AD) (mini-mental state examination \[MMSE\] 18 to 28 points, inclusive). An optional open-label extension (OLE) will be offered after the completion of initial double-blind stage.
