BERWYN, Pa. / Oct 24, 2023 / Business Wire / Annovis Bio, Inc. (NYSE: ANVS), a late-stage clinical drug platform company developing transformative therapies to treat neurodegenerative diseases, including Alzheimer’s Disease (AD) and Parkinson’s Disease (PD), is presenting two posters at the Clinical Trials on Alzheimer's Disease (CTAD) 2023 annual conference held in Boston, Massachusetts, from October 24-27.

Neurotoxic protein overexpression disrupts axonal transport, causing inflammation, loss of function, and nerve cell death. These are all hallmarks of neurodegenerative diseases, including Alzheimer's and Parkinson's. Buntanetap, the drug being developed by Annovis, inhibits the production of all the major neurotoxic proteins responsible for AD and PD before they are produced, while other drugs only target one toxic protein after it has already been produced. This novel mechanism of action makes Annovis' drug a potentially effective treatment option for AD and also for PD.

The posters' collective findings highlight a highly promising treatment for neurodegenerative conditions like Alzheimer's disease and Parkinson's disease. First, in mouse models of Alzheimer's disease and other neurodegenerative diseases, buntanetap has been found to inhibit toxic proteins in the brain, enhance axonal transport, reduce inflammation, and safeguard nerve cells from dying. This has been linked to better cognitive function.

Second, these findings have been replicated in all human AD and PD phase I and II trials to date, demonstrating decreased levels of toxic proteins in the brain, improved axonal transport, reduced inflammation, and neuroprotection. In both mice and humans, buntanetap has not only been safe and well-tolerated but has also improved movement in PD trials and cognition in AD trials. Additionally, in mice and humans, evidence shows a dose-response relationship between drug dose and inhibition of neurotoxic proteins. Currently in phase III trials, Annovis Bio is having discussions with the FDA about the path forward.

Cheng Fang, Ph.D., senior vice president of research and development at Annovis Bio, is presenting two posters at CTAD. In the first - “Phase 3 Clinical Studies in Alzheimer’s and Parkinson’s Diseases; Interim Analysis and FDA Guidance for Both Indications,” provides an overview of the advancements made in its phase III study in early Parkinson’s Disease (PD) and its phase II/III Alzheimer's Disease (AD) study on track for a potential New Drug Application (NDA) that has the potential to be used in the treatment of both these diseases.

In “Do Mouse Data Lie? For Buntanetap, Mouse Data Are Predictive Of Humans” - Annovis conducted a study to see if the data collected from animals would resemble the data collected from humans. Through their research on Alzheimer's disease in mouse models and humans, they were able to reduce the production levels of toxic proteins from disease levels to normal levels. The results consistently showed lower levels of neurotoxic aggregating proteins and significant improvements in cognition after buntanetap treatment.

“It is very exciting to have concordance of results from animal and human studies combined with the human trials being on track with our once daily oral medication yielding no drug-related serious adverse events, low drop out rate and minimal adverse effects,” said Cheng Fang Ph.D., senior vice president of research and development at Annovis Bio. “ As we wait for human trial final results, this is exactly where we want to be.”

The CTAD conference is a gathering that brings together key leaders in Alzheimer's Disease research from both industry and academia to form partnerships with the goal of accelerating the development of effective treatments to combat the disease.

About Annovis Bio, Inc.

Headquartered in Berwyn, Pennsylvania, Annovis Bio, Inc. is a late-stage clinical drug platform company developing transformative therapies that treat neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD) and other chronic and acute neurodegenerative diseases. The Company believes that it is the only company developing a drug that inhibits more than one neurotoxic protein, improves the information highway of the nerve cell, known as axonal transport, reduces inflammation and protects nerve cells from dying in chronic and acute neurodegeneration. Annovis conducted two phase II studies: one in AD patients and one in both AD and PD patients. In the AD/PD study, buntanetap showed improvements in cognition and memory in AD as well as body and brain function in PD patients.
