In Brief

A Phase 1 clinical trial evaluating AV-1959R (Abeta vaccine) for Alzheimer Disease and 2 related conditions. Completed, enrolled 16 participants across 1 site.

Detailed Summary

This Phase 1 clinical trial evaluates the safety, tolerability, and immune response of the adjuvanted AV-1959R vaccine in healthy adults aged 40-60. Participants will receive three intramuscular injections of either adjuvanted AV-1959R (100 µg or 300 µg) or adjuvanted placebo at Weeks 0, 4, and 14, followed by an 8-week follow-up. Researchers will monitor for side effects and measure anti-Aβ antibody levels to assess immune response. This study will help determine if AV-1959R is safe and effective in generating a targeted immune response.

Interventions

AV-1959R (Abeta vaccine)biological

AV-1959R is an investigational adjuvanted vaccine designed to induce a targeted immune response against beta-amyloid (Aβ) to support the primary prevention of Alzheimer's disease and the treatment of asymptomatic preclinical Alzheimer's disease. It is administered intramuscularly (IM) at doses of 100 µg or 300 µg on Weeks 0, 4, and 14, in combination with the adjuvant.
