ANNOVIS BIO ANNOUNCES TWO PRESENTATIONS AT THE AD/PD™ 2023 INTERNATIONAL CONFERENCE ON ALZHEIMER'S AND PARKINSON'S DISEASES

BERWYN, Pa., March 22, 2023 /PRNewswire/ -- Annovis Bio, Inc. (NYSE: ANVS) ("Annovis" or the "Company"), a clinical-stage drug platform company addressing neurodegenerative diseases, today announced the Company will be making two presentations at the upcoming AD/PD^™ 2023 International Conference on Alzheimer's and Parkinson's Disease, which is taking place from March 28 through April 1, 2023, in Gothenburg, Sweden.

The first presentation will discuss the Company's development plan for Parkinson's (PD) and Alzheimer's disease (AD), and the second presentation will show how mouse data fully predicts human outcome in improving function in AD and PD.

Dr. Maria Maccecchini, Chief Executive Officer of Annovis Bio, commented: "AD/PD 2023 provides an important global forum for thought leaders in neurodegenerative disease to discuss some of the most promising development-stage therapies for the treatment of Alzheimer's and Parkinson's disease. Given its unique ability to inhibit the production of multiple neurotoxic proteins, we believe our lead candidate, buntanetap, is well positioned to address both of these large and underserved patient populations, and we look forward to presenting updates for our two programs at this year's meeting."

Dr. Cheng Fang will present on the Company's development plans for buntanetap in both AD and PD in a presentation titled "Phase 3 Clinical Studies in Alzheimer's and Parkinson's Diseases: Interim Analysis of the Parkinson's Clinical Study". Dr. Fang's presentation will cover the study designs of the current Phase 2/3 study in Alzheimer's disease and the Phase 3 study in Parkinson's disease, as well as the interim analysis of the Parkinson's Disease study that includes results from 30% of patients who have received 2 months of treatment. Dr. Feng will also show the planned development to NDA.

Additionally, Dr. Maria Maccecchini will combine and compare old data in mice and new data in humans to show that mouse and rat data are predictive of human outcomes. In the presentation, titled "Do Mouse Data Lie? For Buntanetap They Totally Predict Human Outcome", data from the AD mice, Down Syndrome mice, PD mice, two Phase 1/2 double-blind, placebo-controlled human AD studies and one Phase 2 PD study will be compared to show the consistency on buntanetap's mechanism of action, the reversal of the toxic cascade and the resulting efficacy in AD and PD mice and humans.

Details on the Company's two presentations are provided below.

About Buntanetap
Buntanetap (previously known as ANVS401 or Posiphen) is an oral translational inhibitor of neurotoxic aggregating proteins (TINAPs), which mode of action leads to a lower level of neurotoxic proteins and consequently less toxicity in the brain. In a Phase 2a clinical trial in Alzheimer's disease (AD) and Parkinson's disease (PD) patients, buntanetap was shown to be well-tolerated and safe, and its pharmacokinetics were found to be in line with levels measured earlier in humans, meeting both the primary and secondary endpoints. Additionally, exploratory endpoints were also met, as treatment with buntanetap resulted in statistically significant improvement in motor function in PD patients and cognition in AD patients. Presently buntanetap is being studied in a Phase 3 early PD study and in a Phase 2/3 study in AD patients.

About Annovis Bio, Inc.
Headquartered in Berwyn, Pennsylvania, Annovis Bio, Inc. (Annovis) is a clinical-stage, drug platform company addressing neurodegeneration, such as Alzheimer's disease (AD), Parkinson's disease (PD), and other chronic neurodegenerative diseases. We believe that we are the only company developing a drug for AD and PD that inhibits more than one neurotoxic protein and, thereby, improves the information highway of the nerve cell, known as axonal transport. When this information flow is impaired, the nerve cell gets sick and dies. Annovis conducted two Phase 2 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.
