An Amyloid beta (Abeta) vaccine that safely drives immunity to a key pathological species in Alzheimer’s disease: pyroglutamate Abeta

M. Vukicevic, E. Fiorini, S. Siegert, R. Carpintero, M. Rincon, P. Lopez-Deber, N. Piot, M. Ayer, I. Rentero, C. Babolin, S. Bravo-Veyrat, V. Giriens, C. Morici, M. Beuzelin, A. Gesbert, S. Rivot, S. Depretti, P. Donati, J. Streffer, A. Pfeifer, M. H. Kosco-Vilbois

Preclinical results of our wholly owned anti-Abeta vaccine program ACI-24 show that the optimized formulation generates a potent and sustained immune response. Antibodies showed binding to pyroglutamate Abeta, a highly neurotoxic form of Abeta, which, following recent proof-of-concept from a monoclonal antibody, is a promising target for Alzheimer therapy.
