ANVS-25001 Study:Evaluating Buntanetap for Early Alzheimer's Disease
The ANVS-25001 study is a Phase 3 clinical trial sponsored by Annovis Bio. It investigates the efficacy and safety of Buntanetap (Posiphen) in improving cognition and function in people with early Alzheimer's disease. This oral treatment targets neurotoxic proteins to potentially slow disease progression.

Study goal and design
Targeting neurotoxic proteins to improve cognition
The ANVS-25001 study is a Phase 3, randomized, double-blind, placebo-controlled trial evaluating the efficacy and safety of Buntanetap (Posiphen) in patients with early Alzheimer's disease.
Buntanetap is an orally administered drug designed to inhibit the production of neurotoxic proteins (amyloid-beta, tau, and alpha-synuclein) that accumulate in the brain and impair function. The study aims to determine if the drug can improve cognition and daily functioning over an 18-month period.


Study-related care and support
