Annovis Bio Inc. (NYSE: ANVS) is a late-stage clinical drug platform company pioneering transformative therapies for neurodegenerative disorders such as Alzheimer’s Disease (AD) and Parkinson’s Disease (PD). Annovis Bio stands out by developing a drug that targets multiple neurotoxic proteins simultaneously, aiming to restore axonal and synaptic activity. This innovative approach aims to treat memory loss and dementia associated with AD and body and brain dysfunction associated with PD, making Annovis a unique player in the neurodegeneration space.

Lead Drug Candidate: Buntanetap

Buntanetap (formerly Posiphen) targets neurodegeneration by inhibiting the formation of multiple neurotoxic proteins, including amyloid beta, tau, alpha-synuclein, and TDP43. This multifaceted inhibition improves synaptic transmission and axonal transport, reduces neuroinflammation, and protects nerve cells from dying. Unlike monoclonal antibody therapies, Buntanetap is an orally available small molecule capable of inhibiting multiple neurotoxic proteins at once, positioning it as a comprehensive solution for neurodegenerative diseases.

In a recent Phase II/III Alzheimer’s study, Buntanetap demonstrated statistically significant efficacy. Patients with early AD showed a significantly higher rate of improvement in ADAS-Cog 11 scores across all treatment doses compared to placebo, with a -3.3 point improvement compared to -0.3 for placebo (p < 0.01). Plasma Tau protein levels also reduced, consistent with previous Phase II biomarker data, further validating Buntanetap’s mechanism of action.

Similarly, in the Phase III study of Buntanetap in patients with early Parkinson’s disease, significant advancements were observed. Topline data results are anticipated in June 2024. Preliminary findings indicate promising results in improving cognitive and motor function, underscoring Buntanetap’s potential as a transformative therapy for Parkinson’s disease.

Market Opportunity

The aging population presents a significant market opportunity, with nearly 7 million Americans currently suffering from Alzheimer’s Disease (AD), a figure projected to rise to almost 13 million by 2050​ (Alzheimer’s Association)​​ (Republican Policy Committee)​. Additionally, approximately 1.2 million people in the U.S. have Parkinson’s Disease​ (SingleCare)​.

The economic burden of Alzheimer’s is immense, with care costs expected to reach $360 billion in 2024 and escalate to nearly $1 trillion annually by 2050​​. The need for effective, comprehensive treatments like Buntanetap is more critical than ever.

Company Highlights

  • Innovative Therapeutic Approach: Annovis Bio uniquely targets multiple neurotoxic proteins, aiming to restore nerve cell health and improve cognitive and motor function in AD and PD patients.
  • Robust Clinical Data: Phase II/III studies show significant improvements in cognitive function and biomarker levels in early AD patients.
  • Groundbreaking Clinical Insights: Preliminary results from Phase II studies indicate significant improvements in motor functions and speed in patients with Parkinson’s Disease (PD).
  • Upcoming Phase III Trials: Plans are underway for an 18-month Phase III trial focusing on biomarker-positive early AD patients, designed to further validate Buntanetap’s disease-modifying potential.
  • Capital Efficiency: Annovis Bio is capital-efficient, with zero debt and multiple global patents extending into the 2040s.
