The ‘621 patent covers the use of buntanetap for maintaining or restoring heavy metal homeostasis as a method of prevention in healthy humans or as a method of treatment in sick humans. Metal dis-homeostasis, particularly iron, is a hallmark of various conditions including neurodegenerative diseases, cardiovascular diseases, cancer, and vital organ dysfunction (i.e., brain, heart, liver, lung, and/or kidney).
Iron plays a crucial role in many biological processes including translational regulation of neurotoxic proteins. In neurodegenerative diseases, such proteins include amyloid precursor protein (APP), amyloid-β, tau, α-synuclein, TDP-43, TSE, superoxide dismutase, huntingtin, prion, and c9orf72. The translation of these proteins are regulated by the iron regulatory protein 1 (IRP1) which binds a preserved sequence of mRNA. When this preserved sequence is bound to IRP1, the mRNA is prevented from attaching to the ribosome and being translated. An overload of iron leads to the release of the mRNA from IRP1 and to the translation of the mRNA by the ribosome resulting in the high levels of neurotoxic proteins. Annovis Bio’s lead drug candidate, buntanetap, inhibits the production of these neurotoxic proteins and therefore has broad clinical utility across a wide spectrum of neuro-inflammatory diseases, including Alzheimer’s disease and Parkinson’s disease.
“The basis for this newly issued
The ‘621 patent provides coverage for several aspects of treatment with buntanetap, preventing disease through chronic prophylactic use of buntanetap in healthy humans to maintain iron homeostasis, and use of the drug to restore iron homeostasis in sick humans.
Buntanetap (previously known as ANVS401 or Posiphen) is an oral translational inhibitor of neurotoxic aggregating proteins (TINAPs) which play a role in axonal injury, inflammation, and cell death. By targeting these mechanisms, buntanetap was shown to improve cognitive functions in patients with different neurodegenerative disorders. In Phase 2a clinical trial in AD and PD patients, buntanetap was well-tolerated and safe, and resulted in statistically significant improvement in motor function in PD patients and cognition in AD patients.
About Annovis Bio, Inc.
Headquartered in Berwyn, Pennsylvania, Annovis Bio, Inc. (Annovis) is a clinical-stage, drug platform company addressing neurodegeneration, such as Alzheimer's disease (AD), Parkinson's disease (PD), and other chronic neurodegenerative diseases. We believe that we are the only company developing a drug for AD and PD that is designed to inhibit more than one neurotoxic protein and has a mechanism of action designed to restore axonal and synaptic activity. By improving brain function, our goal is to treat memory loss and dementia associated with AD as well as body and brain function associated with PD. Annovis conducted two Phase 1/2 studies: one in AD patients and one in both AD and PD patients. In the AD/PD study buntanetap showed improvements in cognition in AD as well as body and function in PD patients.
