Annovis (NYSE: ANVS) will present at the 2025 Annual Meeting of the Parkinson Study Group in San Diego, Dec 4-6, 2025.
The company will present Phase 3 Parkinson's disease biomarker data showing that patients with amyloid co-pathology experienced greater cognitive decline that was counteracted and reversed by buntanetap; buntanetap also reduced tau biomarkers. The poster includes a cross-study comparison of completed trials and highlights that patients with amyloid pathology show the largest cognitive gains.
Presentation: Amyloid co-pathology, cognitive decline, and improvement in buntanetap-treated Parkinson’s disease dementia patients by Maria Maccecchini, Ph.D., on Dec 5 at 6:15 p.m. PST; data will be posted on the company website after the meeting.
Annovis (NYSE: ANVS) announced two scientific presentations at the 18th Clinical Trials on Alzheimer’s Disease (CTAD), December 1–4, 2025 in San Diego.
Presentation P073 covers amyloid co-pathology and cognitive decline in buntanetap-treated Parkinson’s disease dementia patients, presented by Cheng Fang, Ph.D. Presentation P007 describes a double 6/18-month Phase 3 study testing symptomatic and potential disease‑modifying efficacy of buntanetap in Alzheimer’s disease, presented by Maria Maccecchini, Ph.D., President and CEO.

Annovis (NYSE: ANVS) announced the FDA scheduled a Type C meeting in January 2026 to discuss the clinical development pathway for buntanetap in Parkinson's disease dementia (PDD). The company said the meeting will cover trial design, patient population, and a potential approval route.
Annovis also reaffirmed that its Phase 3 Alzheimer's disease trial is enrolling on plan with full FDA alignment on study design, endpoints, and population following an End-of-Phase 2 meeting in 2024.

Annovis (NYSE: ANVS) reported Phase 3 data in early Parkinson's disease (NCT05357989) showing buntanetap halted cognitive decline across the study population and produced the largest benefit in patients with mild dementia.
Approximately 25% of participants had amyloid co-pathology and experienced accelerated cognitive decline that was reversed by buntanetap. Treatment also produced measurable reductions in plasma pTau217, total tau, and brain-derived tau, biomarkers linked to Alzheimer’s pathology.
Full biomarker data will be presented at CTAD in San Diego, December 1–4, 2025.
