About Crenezumab
Crenezumab is an anti-Abeta antibody discovered by AC Immune using its SupraAntigen(TM) technology platform and out-licensed to Genentech, a member of the Roche group, in 2006 as a potential therapy for Alzheimer's disease. Crenezumab is a fully humanized IgG4 monoclonal antibody that binds all forms of misfolded Abeta proteins, but especially to Abeta oligomers, to prevent and break up Abeta aggregation and promote Abeta disaggregation. The IgG4 subclass has reduced effector function, allowing microglia to clear Abeta from the brain while minimizing an inflammatory response.

Roche/Genentech is currently evaluating the clinical efficacy and safety of crenezumab in two Phase 3 clinical trials, CREAD 1 and 2, in 750 participants each trial with prodromal or mild Alzheimer's disease, which started in the first quarter of 2016 and the first quarter of 2017, respectively. CREAD 1 was fully recruited in the fourth quarter of 2017 and CREAD 2 completed global recruitment in July 2018. In addition, crenezumab was chosen by an international panel of experts, including the US National Institutes of Health, for use in a first-ever prevention trial in Alzheimer's disease in a large extended family in Colombia (API ADAD) in 2012.

About AC Immune
AC Immune is a clinical-stage Swiss-based biopharmaceutical company, listed on Nasdaq, which aims to become a global leader in precision medicine for neurodegenerative diseases. The Company designs, discovers and develops therapeutic as well as diagnostic products intended to prevent and modify diseases caused by misfolding proteins.

The Company's pipeline features nine therapeutic and three diagnostic product candidates - with five product candidates currently in clinical trials. The most advanced of these is crenezumab, a humanized anti-amyloid-ß monoclonal IgG4 antibody that targets monomeric and aggregated forms of amyloid-ß, with highest affinity for neurotoxic oligomers. Crenezumab is currently in two Phase 3 clinical studies for AD, under a global program conducted by the collaboration partner Genentech (a member of the Roche Group). Other collaborations include Biogen, Janssen Pharmaceuticals, Nestlé Institute of Health Sciences, Piramal Imaging and Essex Bio-Technology.
