Brief summary
The purpose of this observational study is to determine whether the vaccine (UB 311), targeting the N-terminal amino acids (1-14) of the amyloid beta peptide, has long-term immunogenicity and efficacy in individuals diagnosed with mild or moderate Alzheimer's disease (AD) who previously received UB 311-treatment. Amyloid beta was selected as the target antigen based on supporting evidence of the hypothesis that places the accumulation of amyloid beta at the initiating step of AD.
Interventions
Measure anti-Amyloid-beta antibody in serum during 24-26 weeks extension period to 48 weeks (after first vaccine treatment).
