Annovis Provides Corporate Updates and Reports First Quarter 2026 Financial Results

• Phase 3 AD trial: 85% of patients enrolled; full enrollment on track in summer 2026
• PD open-label extension (OLE) study: 40% of patients enrolled; full enrollment on track in fourth quarter 2026
• New Drug Application (NDA) for buntanetap as a symptomatic treatment for AD is expected in early 2027 and as a potential disease-modifying treatment in early 2028
  
  

MALVERN, Pa., May 15, 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 provided business updates and reported financial results for the first quarter ended March 31, 2026.

"We saw strong momentum across both our AD and PD programs in the first quarter," said Maria Maccecchini, Ph.D., President and CEO of Annovis. “Our Phase 3 AD clinical trial achieved significant enrollment growth, keeping us firmly on track to complete randomization of patients in summer 2026 and deliver first top-line results in early 2027. Simultaneously, we launched a PD OLE study and have been encouraged by the robust interest from both returning and new patients. This year is pivotal: we expect to generate substantive clinical data across both indications that will anchor our regulatory path toward an NDA submission for buntanetap."

Clinical highlights

Alzheimer’s disease – pivotal Phase 3 trial (NCT06709014)

• Enrollment: 85% of patients enrolled.
• Screening: On May 15, 2026, Annovis closed enrollment to new participants after reaching a sufficient number of patients in screening to meet the trial's enrollment goal.
• Safety: Annovis received a positive recommendation from the Data and Safety Monitoring Board (DSMB) regarding the drug’s safety at 6 months, supporting seamless continuation of the study.
• Study design: The pivotal Phase 3 AD trial is recruiting early AD patients positive for pTau217 plasma biomarker. The study is designed to evaluate buntanetap's symptomatic effect at 6 months and its potential disease-modifying effect at 18 months.
  
  

Parkinson’s disease – OLE study (NCT07284784)

• Enrollment: 40% of patients enrolled.
• Skin biomarker: The PD OLE study is implementing a biomarker test measuring levels of phosphorylated alpha-synuclein and nerve cell fiber density via skin biopsy.
• Digital biomarker: Annovis entered into a partnership with NeuroRPM to integrate an AI-powered digital biomarker, enabling continuous, real-world assessment of motor functions in response to buntanetap.
• Study design: The PD OLE study is designed to evaluate buntanetap's safety and long-term efficacy over the period of 36 months in participants from prior Annovis’ trials as well as in new patients who had deep brain stimulation (DBS) surgery.
  
  

Corporate highlights

• Publications
  • Annovis published a byline article in The Scientist, tracing the 170-year scientific history of buntanetap, from the origins of its predecessor compound to its mechanism of action and key events that shaped the drug’s clinical development.
  • Annovis announced a peer-reviewed publication of the Phase 2/3 AD clinical trial results in Nature NPJ Dementia, available open access, demonstrating a dose-dependent cognitive improvement and biomarker reductions in patients treated with buntanetap.
    
    
• Presentations
  
  • Cheng Fang, Ph.D., SVP, R&D, presented two posters at the AD/PD2026 conference, highlighting clinical data which support buntanetap's treatment effect in PD with a particular focus on cognition and biomarker findings as well as an update on the ongoing pivotal Phase 3 AD trial.
  • Maria Maccecchini, Ph.D., President and CEO, presented at Fierce Biotech Week 2026 in Boston, delivering a talk titled "The Multi-Protein Reality of Alzheimer's Disease: What the Science Has Known for Decades and What the Field Has Yet to Accept," making the scientific case for targeting multiple neurotoxic proteins in AD and presenting buntanetap's clinical evidence of cognitive and biomarker improvements.
    
    
• Patents
  
  • Annovis secured a U.S. patent, covering prevention and treatment of neurological injuries arising from brain infections through the administration of buntanetap or related compounds.
    
    

Upcoming milestones

• Phase 3 AD study: Annovis expects to reach full enrollment in summer 2026. The symptomatic data readout is anticipated approximately 6 months after the last patient is dosed. The disease-modifying data readout is anticipated 18 months after the last patient is dosed.
• PD OLE study: Annovis expects to complete enrollment for the PD OLE study in the fourth quarter of 2026.
• NDA pathway: Based on the Phase 3 AD study outcomes, Annovis plans to engage with the FDA regarding a regulatory NDA submission for buntanetap as a symptomatic treatment for AD in early 2027 and as a disease-modifying treatment in early 2028.
