Annovis Provides Corporate Updates and Reports Third Quarter 2025 Financial Results

MALVERN, Pa., Nov. 12, 2025 (GLOBE NEWSWIRE) -- Annovis Bio, Inc. (NYSE: ANVS) ("Annovis" or the "Company"), a late-stage clinical drug platform company pioneering transformative therapies for neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD), today provided corporate updates and third quarter 2025 financial results.

"The past quarter delivered breakthrough progress on every front," said Maria Maccecchini, Ph.D., President and CEO of Annovis. "Our pivotal Phase 3 Alzheimer's study has achieved full activation across all clinical sites, with enrollment momentum advancing every day. We have fortified our intellectual property position by transferring all patents to our new crystal form of buntanetap while publishing compelling pharmacokinetic data that validates this milestone. The addition of a seasoned CFO strengthens our executive team precisely when it matters most. Adding to all this, we are particularly encouraged by the new biomarker findings from our Phase 2/3 study showing meaningful reductions in inflammation and neurodegeneration—powerful evidence of buntanetap's disease-modifying potential. Every element is now aligned as we move toward our data readouts—the final step before an NDA submission."

Clinical highlights – pivotal Phase 3 AD study

• Annovis’ pivotal Phase 3 study in early AD (NCT06709014) remains on track, with all 84 clinical sites fully activated, recruiting, and treating participants across the U.S.
• The trial has generated robust participation, reflecting growing enthusiasm from the patient community. The screen failure rate remains within expected projections.
• The first patients have successfully completed the 6-month treatment period, a key milestone for the upcoming symptomatic readout, reinforcing steady progress toward trial completion.

Business highlights

• In October, Annovis announced encouraging biomarker results from its Phase 2/3 AD trial, showing profound reductions in key markers of neuroinflammation and neurodegeneration after treatment with buntanetap compared to placebo. The effect was observed in patients with mild and moderate stages of the disease. These findings further validate the drug’s ability to halt the toxic cascade and reinforce its potential as a potential disease-modifying therapy.
• In September, Annovis published a new peer-reviewed article highlighting the pharmacokinetics (PK) of the novel crystalline form of buntanetap and its comparison to the original form. The study, which included data from mice, dogs, and humans, demonstrated a better solid-state stability of the new form while preserving its PK profile and metabolism. The article was published following the Company's announcement that all patents have been successfully transferred to the new crystal form, securing comprehensive global intellectual property protection through 2046.
• That same month, Annovis strengthened its leadership team with the appointment of Mark Guerin as CFO, a seasoned executive with a proven track record in driving financial strategy and operational excellence across biopharma organizations.
• In August, Annovis’ management attended the AAIC 2025 conference in Toronto, where it presented four scientific posters, covering the progress of its Phase 3 Alzheimer’s trial and PK characterization of buntanetap.

• Annovis’ cash and cash equivalents totaled $15.3 million as of September 30, 2025, compared to $10.6 million as of December 31, 2024.
