Annovis Bio CEO Maria Maccecchini Issues Letter to Stockholders

MALVERN, Pa., May 06, 2024 (GLOBE NEWSWIRE) -- Annovis Bio, Inc. (NYSE: ANVS) (“Annovis” or the “Company”), a clinical-stage drug platform company developing novel therapies for neurodegenerative diseases, announced that Maria Maccecchini, Founder, President, and CEO of Annovis, issued a letter to stockholders providing a review of Phase II/III data from its Alzheimer’s study and sharing next steps.

Dear Friends,

The last few days have been very difficult. I received a lot of emails and phone calls that often expressed anger, uncertainty, and disappointment. Additionally, our results were questioned and criticized. This reaction not only caused a drastic drop in our share price, but, more importantly, it saddened the Annovis team. We are determined to develop a drug that treats Alzheimer’s (AD) and Parkinson’s diseases (PD) and makes the life of the afflicted people and their caretakers easier. However, every setback makes it harder to reach this goal.

At Annovis, we hold rigorous science, open communication, and transparency seriously, and it is our responsibility to conduct a clinical study in conformance with FDA guidelines and to the highest standards possible. In science, results are often less than perfect, but they pave the way for a better plan when designing and executing the next steps.

The Phase II/III study provided us with valuable information for an improved Phase III pivotal trial. First, we will prescreen patients for plasma AD biomarkers to confirm the diagnosis. Second, we will only enroll patients with early and mild Alzheimer’s (MMSE 21-28), the subpopulation which showed the highest level of improvement after buntanetap, as seen from our completed AD studies (Table 1).

Phase II/III; 2024MMSE 14-20112ADAS-Cog113 months-0.651.79

Table 1. Summary of cognitive response to buntanetap at different disease stages measured in completed AD studies conducted by Annovis. The table clearly shows a strong response in patients with early AD (MMSE 18-28 and MMSE 21-24), while in moderate AD patients (MMSE 14-20), the response is obscured by high placebo effect.

The goal of the Phase II/III trial was to learn about the breadth of our drug’s efficacy and to obtain information for a pivotal disease-modifying study. This goal was achieved. We believe that the FDA will accept buntanetap for symptomatic relief and will allow us to continue with the next pivotal Phase III study for disease-modification.

About Buntanetap

Buntanetap (formerly known as Posiphen or ANVS401) attacks neurodegeneration by inhibiting the formation of multiple neurotoxic proteins - amyloid beta, tau, alpha synuclein, and TDP43 - thereby improving synaptic transmission, axonal transport and neuroinflammation. Dysregulation of these pathways has been shown to be the cause of nerve cell degeneration and ultimately death. By attacking these pathways, buntanetap has the ability to reverse neurodegeneration in Alzheimer’s, Parkinson’s, and other neurodegenerative diseases.
