MALVERN, Pa., March 31, 2026 (GLOBE NEWSWIRE) -- Annovis Bio, Inc. (NYSE:ANVS) ("Annovis" or the "Company"), a Phase 3 clinical-stage biotechnology company developing the investigational oral therapy, buntanetap, for neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD), today announced the publication of an article in The Scientist titled "Buntanetap: From Execution Poison to Potential Alzheimer's Disease Drug", examining the history of discovery and development of buntanetap, the Company's lead drug candidate.

As Annovis advances its clinical pipeline with both AD and PD trials actively enrolling patients, this historical review offers important context for understanding buntanetap's scientific journey and its significance in the neurodegenerative disease space. The article traces the compound's development from its 19^th-century origins and the identification of its mechanism of action to the search for the correct chemical form and its progression through clinical trials. It also illuminates the complex journey of drug development shaped by scientific rigor, cultural context, and corporate evolution, providing an accessible yet scientifically grounded account of the discovery, optimization, and refinement that have brought buntanetap to its current stage of development. Buntanetap is currently being evaluated in a pivotal Phase 3 study in early AD (NCT06709014), with 70% patients enrolled, and in an open-label extension study in PD (NCT07284784), with 20% patients enrolled.

"Buntanetap is the product of more than a century and a half of pharmacological refinement and clinical learning," said Alexander Morin, Ph.D., Director of Strategic Communications at Annovis. "This article is an opportunity to share that story in accessible language, tracing the key moments that have brought buntanetap to where it stands today. It also reflects Annovis' commitment to scientific transparency and education as we approach important clinical and regulatory milestones."
