Addressing Alzheimer’s, Parkinson’s and other neurodegenerative diseases


Our clinical stage pipeline uniquely integrates diagnostic and therapeutic candidates as well as different treatment modalities (such as antibodies, vaccines and small molecule drugs) against the most promising validated therapeutic targets.

Pioneering Precision Medicine

AC Immune develops the tools to enable detection and clearance of pathological proteins underlying neurodegenerative diseases. Identifying and targeting these misfolded proteins and related pathways in each patient will be key to achieving best possible efficacy.
