AV-1980R (Tau Vaccine) in Preclinical Alzheimer's Disease (TAURUS-1980)

We're still translating this one. In a couple of days, you'll see what this trial actually tests — and whether it matters for APOE4 carriers like you. For now, here's the sponsor's own description:

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.
