Safety Study of AADvac1, a Tau Peptide-KLH-Conjugate Active Vaccine to Treat Alzheimer's Disease

Summary

This first-time-in-man study is mainly designed to assess the safety and tolerability of AADvac1 in the treatment of Alzheimer's disease. AADvac1 is a vaccine directed against pathologically modified Alzheimer tau protein that is the main constituent of neurofibrillary tangles (NFTs), and is intended to be a disease-modifying treatment for Alzheimer's disease, i.e. to halt its progress. As this study is a Phase I study focused on tolerability and safety, efficacy will be assessed in an exploratory manner.
