Brief Summary: This is a Phase 1, multicenter, randomized, double-blind, placebo-controlled, multiple dose-escalating trial to evaluate the safety, tolerability, and immune response of AV-1980R, an investigational vaccine targeting tau protein, in participants with preclinical Alzheimer's disease. Up to 48 cognitively unimpaired adults aged 65-80 with biomarker evidence of early Alzheimer's disease will be enrolled into three ascending dose cohorts. The study is designed as a secondary prevention trial to test whether therapeutic immunization at the preclinical stage is safe, induces an immune response, and, exploratorily, may favorably affect biomarkers associated with disease progression.
Detailed Description: This first-in-human study investigates AV-1980R, a MultiTEP-based active immunotherapy formulated with the adjuvant, as a secondary prevention approach for Alzheimer's disease. The study will randomize up to 48 participants aged 65-80 years in a 3:1 ratio to AV-1980R or placebo across three ascending dose cohorts (20 μg, 60 μg, 180 μg). Participants will receive four intramuscular doses at Weeks 0, 4, 12, and 36, with follow-up through Week 56.

Primary objectives are to evaluate safety and tolerability, monitored by adverse events, labs, ECGs, MRI, and neurological assessments. Secondary objectives include immunogenicity measured by anti-tau antibody titers. Exploratory endpoints include plasma biomarker and tau-PET changes.
