Company profile

Company website

AC Immune S.A. is a biotech firm operating at the clinical stage, dedicated to pioneering, formulating, and advancing therapeutic agents and diagnostic tools. Its core mission is addressing neurodegenerative conditions rooted in protein misfolding, both preventatively and therapeutically. Leveraging its proprietary SupraAntigen and Morphomer platforms, the company engineers a range of vaccines, antibodies, and small molecules specifically designed to engage with aberrantly folded proteins implicated across various neurodegenerative disorders. Its pipeline features Crenezumab, a humanized, conformation-specific monoclonal antibody currently undergoing a Phase II clinical prevention trial for Alzheimer's disease (AD). Additionally, AC Immune is advancing ACI-24, an anti-Abeta vaccine candidate, which is in Phase II clinical evaluation for AD and has successfully completed a Phase Ib study for Down syndrome. Other key candidates include ACI-35, an anti-Tau vaccine candidate that has finished Phase Ib clinical assessment, and a Tau-positron emission tomography (PET) imaging tracer, also in Phase II development. Furthermore, the company is engaged in the research and development of small molecule inhibitors to prevent Tau aggregation, targeting AD and various NeuroOrphan indications. Early-stage efforts include discovery and preclinical programs for a spectrum of neurodegenerative diseases, encompassing diagnostic agents aimed at TDP-43, alpha-synuclein, and NLRP3. The company maintains strategic partnerships and licensing agreements with key industry players such as Genentech, Inc., Biogen International GmbH, Janssen Pharmaceuticals, Inc., Life Molecular Imaging SA, Eli Lilly and Company, and WuXi Biologics. Founded in 2003, AC Immune S.A. is headquartered in Lausanne, Switzerland.
