MALVERN, Pa., May 13, 2024 (GLOBE NEWSWIRE) -- Annovis Bio, Inc. (NYSE: ANVS) (“Annovis” or the “Company”), a clinical-stage drug platform company developing novel therapies for neurodegenerative diseases, provided updates from across the organization and announced first quarter financial results.

Clinical Updates

AD Phase II/III Study

• On April 29, Annovis announced statistically significant Phase II/III data in patients with early Alzheimer’s disease (AD).
  • Significantly higher rate of improvement in ADAS-Cog 11 scores in each treatment dose relative to placebo for patients with mild AD;
  • Improvement in cognition measured by ADAS-Cog 11 at three months was 3.3 points as compared to 0.3 for placebo, consistent with previous Phase II AD/PD and Discovery studies;
  • Plasma Tau protein levels were reduced, consistent with previous Phase II biomarker data.

• Based on the findings of this short study, Annovis plans to conduct a pivotal 18-month disease-modifying Phase III trial in biomarker-positive early AD patients.
  

PD Phase III Study

• On January 24, Annovis refined the timeline for Parkinson’s disease (PD) Phase III data announcement, originally set for the end of January, due to necessary cleaning efforts required to deliver reliable and accurate results.

• On May 9, Annovis announced unblinding of the Phase III data and intends to release topline results in June of 2024.

• The Phase III trial was a randomized, double-blind, placebo-controlled trial investigating the efficacy, safety, and tolerability of buntanetap for early PD patients, on top of their existing standard of care. Patients were treated with 10 mg, 20 mg, or placebo for 6 months. Out of 616 patients screened, 523 were randomized and 471 completed the study across 67 sites (43 in the United States and 24 in the European Union).
  

Patents

• Annovis announced on January 30, 2024 the filing of a patent application covering the use of buntanetap and its analogues for the treatment of neuropsychiatric indications.

• This patent follows the U.S. Provisional Application No. 63/440,890, which was filed on January 24, 2023.

• This patent application addresses mental illnesses such as autism, attention deficit-hyperactivity disorder, bipolar disorder, major depressive disorder, anxiety and schizophrenia, which have been shown to share similar pathological abnormalities with certain neurodegenerative diseases, including disruptions in synthesis of neurotoxic proteins, impairment of axonal transport, inflammation, and nerve cell death.
  

First Quarter 2024 Financial Results

• The Company’s cash and cash equivalents totaled $3.1 million as of March 31, 2024, compared to $5.8 million as of December 31, 2023. The Company estimates that active management of its cash and working capital positions, combined with the $0.8 million cash received in connection with its previously announced ELOC Purchase Agreement, will fund its operations into the fourth quarter of 2024. The Company had 11.0 million shares of common stock outstanding as of March 31, 2024.

• Total operating expenses for the three months ended March 31, 2024 were $7.8 million, which included research and development expenses of $6.5 million and general and administrative expenses of $1.3 million. This compares to total operating expenses for the three months ended March 31, 2023 of $10.0 million, which included research and development expenses of $7.8 million and general and administrative expenses of $2.2 million.

• Other income for the three months ended March 31, 2024 was $6.7 million, which included a $6.7 million non-cash gain from change in fair value of liability-classified warrants. This compares to other income for the three months ended March 31, 2023 of $0.2 million, which included $0.2 million of interest income.

• Annovis reported basic net loss per common share of $0.10 and diluted net loss per common share of $0.72 for the three months ended March 31, 2024. This compares to a basic net loss per common share of $1.19 and diluted net loss of $1.19 for the three months ended March 31, 2023.
  

Conferences

• Annovis participated in the International Conference on Alzheimer’s and Parkinson’s Diseases (AD/PD™ 2024), which took place in Lisbon, Portugal from March 5-9, 2024.

• On March 7, Maria Maccecchini participated in a forum discussion titled “New Insights in the Development of Biomarkers, Imaging, and Therapy of Alpha-Synuclein, LRKK2, and GBA Pathologies”.
  

Message from Dr. Maria Maccecchini

“The first quarter proved to be pivotal for our company as we continued to wind down our two recent clinical trials - Phase III in Parkinson’s and Phase II/III in Alzheimer’s. For our PD study, which concluded late last year, diligent efforts are underway to meticulously prepare the data, with expected delivery of topline results in June of this year. For the AD study, we successfully cleaned the data and were proud to announce cognitive improvements as measured by ADAS-Cog 11 in patients with early AD, showing us a pathway for continued clinical development of buntanetap. We extend our heartfelt gratitude to the patients and their families whose contribution was the driving force of our research aimed to bring new treatments to the market.”

About Buntanetap
Buntanetap (formerly known as Posiphen or ANVS401) attacks neurodegeneration by reducing multiple neurotoxic proteins, thereby improving synaptic transmission and axonal transport, which is the information highway of the nerve cell. Dysfunction of synaptic transmission and axonal transport has been shown to be the cause of nerve cell degeneration and ultimately death. Unlike other drugs in development which attempt to remove only one toxic protein, buntanetap inhibits several toxic proteins before they can form, thereby preventing the formation of all the major neurotoxic proteins responsible for PD and AD.

About Annovis Bio, Inc.
Headquartered in Malvern, Pennsylvania, Annovis Bio, Inc. is a clinical-stage, drug platform company addressing neurodegeneration, such as Alzheimer’s disease (AD), Parkinson’s disease (PD), and other chronic neurodegenerative diseases. It is believed to be the only company developing a drug for both AD and PD designed to inhibit more than one neurotoxic protein to restore axonal and synaptic activity. By improving brain function, the company’s goal is to treat memory loss and dementia associated with AD as well as body and brain dysfunction associated with PD.
