This Phase 1 study will test the safety and immune response of the investigational vaccine DUVAX in healthy adults. Participants will be randomly assigned to receive either DUVAX or placebo by intramuscular injection. The study will evaluate how well the vaccine is tolerated and whether it produces antibodies against Alzheimer's disease-related proteins.
This is a first-in-human, randomized, double-blind, placebo-controlled Phase 1 trial of DUVAX, an adjuvanted vaccine, in up to 24 healthy participants aged 40-65 years. Two dose levels (200 µg and 400 µg) will be evaluated. Participants will receive three intramuscular doses at Weeks 0, 4, and 22, with safety and immunogenicity monitoring through one year after the last vaccination. The primary objective is to assess safety and tolerability. The secondary objective is to measure immunogenicity by evaluating antibody responses against amyloid beta (Aβ) and tau proteins.
