Recent Highlights and New Developments

• Clinical Advancement of buntanetap for PD: The Company held a successful Type B meeting with the FDA with regard to the Company's planned Phase 3 clinical studies of buntanetap for the treatment of Parkinson's Disease (PD). The FDA provided feedback on the initiation of the Phase 3 clinical studies of buntanetap for PD in parallel with the Alzheimer's disease (AD) program. The agency detailed guidance on the specific endpoints, entry criteria, and further study parameters for two Phase 3 studies that would support a broad indication for both early and late PD.
  
  
• Announced Phase 3 Trial Design for PD: The Company announced the trial design of the upcoming Phase 3 trial evaluating buntanetap in early PD. The study is designed to enroll 450 PD patients with Hoehn & Yahr scale scores of 1, 2 and 3 and randomize them at 1:1:1 ratio into placebo, 10mg or 20mg buntanetap once daily on top of their standard of care for six months. Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II and III will be used as primary endpoints, while total MDS-UPDRS and Participant Global Impression of Change will be secondary endpoints. In addition, Wechsler Adult Intelligence Scale, plasma biomarkers and Mini-Mental State Examination will be evaluated as exploratory endpoints.

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, including Alzheimer's in Down Syndrome (AD-DS). We believe that we are the only company developing a drug for AD, PD, and AD-DS 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.
