About this trial

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.

Trial outcomes

Primary outcomes

1

Participants with Treatment-Emergent Adverse Events (TEAEs), including Adverse Events of Special Interest (AESI)

Safety will be assessed by recording the number and type of treatment-emergent adverse events (TEAEs), including adverse events of special interest (AESI), reported from baseline through the follow-up period. Events will be summarized by severity and relationship to study treatment.

Time frame
From baseline (Day 1) through Week 74 (end of study follow-up)

Secondary outcomes

1

Serum anti-Aβ antibody titers (IgM, IgG, and IgG subclasses)

Immunogenicity will be assessed by measuring antibody titers against amyloid-beta (Aβ), including total IgM, total IgG, and IgG subclasses (IgG1, IgG2, IgG3, IgG4). Changes from baseline will be compared.

Time frame
Baseline, Weeks 2, 4, 6, 22, 25, and 38

Other outcomes

1

Serum anti-Tau antibody titers (IgM, IgG, and IgG subclasses)

Immunogenicity will be assessed by measuring antibody titers against tau protein, including total IgM, total IgG, and IgG subclasses (IgG1, IgG2, IgG3, IgG4). Changes from baseline will be compared.

Time frame
Baseline, Weeks 2, 4, 6, 22, 25, and 38
2

Serum anti-MultiTEP antibody titers (IgM, IgG, and IgG subclasses)

Immunogenicity will be assessed by measuring antibody titers against MultiTEP carrier epitopes, including total IgM, total IgG, and IgG subclasses (IgG1, IgG2, IgG3, IgG4). Changes from baseline will be compared.

Time frame
Baseline, Weeks 2, 4, 6, 22, 25, and 38
