• The company believes the FDA will accept buntanetap for symptomatic relief.
• The company is focusing on a specific patient subpopulation (early and mild AD) that has shown the most improvement with buntanetap.
• Buntanetap targets multiple neurotoxic proteins, which could have a broad impact on neurodegenerative diseases.
• The company is committed to rigorous science, open communication, and transparency.

Negatives

• The Phase II/III study results led to a drastic drop in the company's share price.
• The study results were questioned and criticized.

• The company's forward-looking statements are subject to known and unknown risks and uncertainties that may cause actual results to differ materially.

Future Outlook

The company plans to conduct an improved Phase III pivotal trial, focusing on patients with early and mild Alzheimer's, and believes the FDA will accept buntanetap for symptomatic relief, allowing them to proceed with a pivotal Phase III study for disease modification.

Industry Context

The announcement comes amid ongoing efforts to develop effective treatments for neurodegenerative diseases like Alzheimer's and Parkinson's, which are significant unmet medical needs. The focus on specific patient subpopulations and the targeting of multiple neurotoxic proteins are approaches being explored by other companies in the field.

Comparison to Industry Standards

• The ADAS-Cog11 scores reported in the Annovis Bio study are within the range of results seen in other clinical trials for Alzheimer's treatments, but the high placebo effect in moderate AD patients is a concern.
• Companies like Biogen and Eli Lilly have also faced challenges in demonstrating efficacy in Alzheimer's trials, highlighting the complexity of the disease.
• The focus on early-stage Alzheimer's patients is consistent with the trend in the industry to target the disease at earlier stages when interventions may be more effective.
• The approach of targeting multiple neurotoxic proteins is a novel approach compared to some other companies that focus on single targets like amyloid beta.

Stakeholder Impact

• Shareholders experienced a significant drop in share price due to the study results.
• The Annovis team was saddened by the criticism and the impact on the share price.
• Patients and their caretakers are impacted by the setbacks in the development of treatments for neurodegenerative diseases.

Next Steps

• The company will prescreen patients for plasma AD biomarkers in future trials.
• The company will focus on enrolling patients with early and mild Alzheimer's (MMSE 21-28) in future trials.
• The company plans to conduct an improved Phase III pivotal trial.
