MALVERN, PA — Annovis Bio, Inc. (NYSE: ANVS) announced a significant milestone in its research with the publication of a new article in the journal Biomolecules. The study focuses on the comparison of pharmacokinetic profiles of Posiphen (or buntanetap) across different species, including humans, as part of a special issue on the role of amyloid protein in neurological diseases.
“This publication is a testament to many years of research at Annovis,” said Maria Maccecchini, Ph.D., Founder, President, and CEO of Annovis. “While we have conducted numerous studies to advance our Posiphen pipeline, this is the first systematic and comprehensive comparison in multiple animal and human samples. Consolidating all this data into one publication offers a more holistic view of Posiphen, enhancing our understanding of its mechanisms.”
The study, titled “Comparative Analysis of Posiphen Pharmacokinetics across Different Species—Similar Absorption and Metabolism in Mouse, Rat, Dog and Human,” brings together findings from various preclinical and clinical studies. By evaluating how Posiphen is absorbed, distributed, metabolized, and excreted across different species, researchers aim to identify which animal models most closely mimic human responses.
Key highlights from the study include:
- Posiphen rapidly reaches peak concentration in plasma, followed by high absorption in the brain and cerebrospinal fluid (CSF).
- The drug metabolizes into two primary metabolites: N1-norposiphen and N8-norposiphen.
- Both Posiphen and its metabolites exhibit rapid clearance in animal models and human subjects; however, they stay longer in the CSF and brain.
- Absorption, distribution, metabolism, and excretion of Posiphen are similar in healthy volunteers and patients with Alzheimer’s and Parkinson’s diseases.
Unlocking the Potential: Advancing Drug Development with Posiphen
This research is important for several reasons. Understanding how Posiphen behaves in different species helps scientists determine the most accurate animal models for future studies, potentially accelerating the path to clinical trials and drug approval. Additionally, these insights could improve dosing strategies and therapeutic efficacy, ultimately benefiting patients with neurological disorders like Alzheimer’s and Parkinson’s diseases.
From a broader perspective, this study highlights the complexities of drug development and the importance of thorough, cross-species analysis. Some experts argue that reliance on animal models can be limiting and advocate for more advanced, human-specific testing methods. Others maintain that animal studies remain crucial for early-stage drug development and safety assessments.
As Annovis Bio continues to advance its Posiphen pipeline, the pharmaceutical community will watch closely. Success in this area could lead to new, effective treatments for debilitating conditions, offering hope to millions of patients and their families.
While some remain cautious about the translation of animal model results to human outcomes, the comprehensive nature of this study strengthens the foundation for future clinical applications.
