Fourth Quarter Highlights and New Developments

• Received approval for European Union clinical trial sites for the Phase 3 study of buntanetap for the treatment of early Parkinson's disease: On February 8, 2023, the Company announced the approval for additional European clinical trial sites for the ongoing Phase 3 study of buntanetap for the treatment of Parkinson's disease ("PD"). Annovis is actively recruiting for the ongoing Phase 3 study with approximately 53 clinical trial sites open and currently enrolling in the United States. The approval adds an additional approximately 49 sites in the EU for the Company's Phase 3 study of buntanetap for the treatment of Early PD.
  
  
• Announced filing of patent application covering the administration of buntanetap and its analogues for the treatment of mental illnesses: On February 1, 2023, the Company announced the filing of a provisional patent application that extends the breadth of its platform from neurodegenerative to neuropsychiatric indications: "Treatment of mental illness via administration of buntanetap and analogues."
  
  
• Announced new appointments to strengthen its senior leadership team: On January 6, 2023, the Company announced the appointment Michael Christie, Ph.D. as Vice President of Process Chemistry and David Prohaska as Vice President of Toxicology and Pharmacology. Dr. Christie has over 40 years of experience in the pharmaceutical industry and formally served as the Senior Director of Chemical Process and R&D for Teva Pharmaceuticals. Mr. Prohaska brings 25 years of experience in all aspects of preclinical drug development and has a long track record of successful FDA submissions with multiple drug approvals. Mr. Prohaska joined Annovis from Aravive Biologics where he served as the Director of Preclinical Development and Clinical Operations Support.
  
  
• Publication of Phase 1/2 clinical data in The Journal of Prevention of Alzheimer's Disease: On October 11, 2022, the Company announced the publication of a study, titled 'Buntanetap, a Novel Translational Inhibitor of Multiple Neurotoxic Proteins, Proves to Be Safe and Promising in Both Alzheimer's and Parkinson's Patients', evaluated safety, pharmacokinetics, biomarkers, and efficacy of buntanetap in treating early AD and PD patients. Buntanetap was observed to be well tolerated and significantly improved cognition in AD patients and motor function in PD patients.
  
  
• Receipt of FDA authorization to proceed with Phase 2/3 trial for buntanetap in mild to moderate Alzheimer's disease (AD): On October 6, 2022, the Company announced that the FDA authorized the Phase 2/3 clinical study of buntanetap in mild to moderate AD. The Phase 2/3 study is a randomized, double-blind, placebo-controlled trial investigating the efficacy, safety, and tolerability of buntanetap in mild to moderate AD patients. The trial will enroll a total of 320 mild to moderate AD patients to be treated with 7.5, 15 or 30mg of buntanetap or placebo, in addition to any drugs they regularly take, for three months.
  
  
• Interim analysis for Phase 3 study of buntanetap for the treatment of early Parkinson's disease (PD): On March 31, 2023, the Company announced that it had received the results of the pre-planned blinded interim analysis conducted by a data analytics provider based on 132 patients from all cohorts collectively for which baseline and two-month data was available. As the interim analysis was conducted at two months of the six-month endpoint and only on 132 patients, it may not be indicative of the results at six months for the full patient population because as the trial progresses, clinical outcomes may materially change as patient enrollment continues and more patient data become available, or different conclusions or considerations may qualify such results once additional data have been received and fully evaluated. Based on the results of the interim analysis, the Company intends to proceed with the trial as planned in accordance with the previously established protocol.

Maria L. Maccecchini, Ph.D., Founder, President, and CEO of Annovis, commented: "The fourth quarter and subsequent announcements in early 2023 highlight continued execution and productivity across many facets of our business. We are pleased with the pace of enrollment in our ongoing clinical trials. We expect to report a blinded interim analysis of our Phase 2/3 Alzheimer's study in Fall 2023. We are also building an expansive intellectual property estate surrounding the use of buntanetap and its analogues across a myriad of neuro-inflammatory diseases and conditions. As our clinical activities continue to expand, we are also managing this growth through the appointments of key senior-level professionals who will play a pivotal role as we reach key inflection points in our clinical programs. We believe 2023 promises to be an exciting year for Annovis driven by our team's continued execution, and the strong therapeutic potential of our lead drug candidate, buntanetap, to address the unmet medical need in Alzheimer's and Parkinson's disease."

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 1/2 clinical trial in Alzheimer's disease (AD) and Parkinson's disease (PD) patients, buntanetap was shown to be well-tolerated 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 study in early PD patients and in a Phase 2/3 study in mild to moderate 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 is designed to inhibit more than one neurotoxic protein, and has a mechanism of action designed to restore nerve cell axonal and synaptic activity.. By improving brain function, our goal is to treat memory loss and dementia associated with AD as well as body and brain function associated with PD.  Annovis conducted two Phase 1/2 studies: one in AD patients and one in both AD and PD patients. In the AD/PD study buntanetap showed improvements in cognition in AD as well as body and function in PD patients.
