AC Immune SA, a clinical stage biopharmaceutical company, discovers, designs, and develops medicines, and therapeutic and diagnostic products for the prevention and treatment of neurodegenerative diseases associated with protein misfolding. The company’s SupraAntigen and Morphomer platforms are designed to generate biologics and small molecules, which selectively interact with misfolded proteins that are common in a range of neurodegenerative diseases. It develops Crenezumab, a humanized, conformation specific monoclonal antibody used to slow Alzheimer’s disease (AD) progression; and Semorinemab, an investigational monoclonal anti Tau antibody that targets the N-terminal portion of the Tau protein and is designed to bind to Tau and slow its spread between neurons for the treatment of AD. The company is also developing ACI-24.060 for the treatment of down syndrome related AD; ACI-7104.056 to treat Parkinson’s disease; and ACI-35.030, designs to stimulate a patient’s immune system to produce antibodies against pathological phosphorylated Tau.
