Annovis Bio Files Patent for New Composition of Matter for Buntanetap

MALVERN, Pa., June 26, 2024 (GLOBE NEWSWIRE) -- via IBN – Annovis Bio Inc. (NYSE: ANVS) (“Annovis” or the “Company”), a late-stage clinical drug platform company pioneering transformative therapies for neurodegenerative disorders such as Alzheimer’s Disease (AD) and Parkinson’s Disease (PD), announces the filing of the new composition of matter patent with the U.S. Patent and Trademark Office covering novel solid forms of buntanetap, selecting the best crystal, and building upon the provisional patent filed in June 2023.

This patent covers novel crystalline forms of buntanetap and their use for treating and/or preventing various neurodegenerative conditions. Crystalline forms offer significant advantages over less structured forms, including better solubility and stability. The most stable crystal form of buntanetap (CAS# 3032752-92-1) has been selected as the new lead compound for animal bridge studies and for developing a manufacturing process. The bridge studies were submitted to the FDA and will be discussed in July. The goal is to continue development of our drug and file the NDA with the new crystal form.

“The invention of a new solid form of our drug, buntanetap, and the subsequent patent filing represent groundbreaking milestones for our company. This achievement will allow us not only to continue advancing our pipeline, but also to enhance the drug's properties, ultimately providing greater benefits to our patients,” said Maria Maccecchini, Ph.D., Founder, President, and CEO of Annovis.

A composition of matter patent comes with protection for the new buntanetap crystalline form and all its uses for a 20-year term.  The composition of matter patent is the single most important patent for any pharmaceutical company developing a new drug because it provides adequate runway to develop a drug and bring it to market.

About Buntanetap
Buntanetap (formerly known as Posiphen or ANVS401) targets neurodegeneration by inhibiting the formation of multiple neurotoxic proteins, including amyloid beta, tau, alpha-synuclein, and TDP43. This action improves synaptic transmission, axonal transport, and reduces neuroinflammation. Dysregulation of these pathways has been shown to cause nerve cell degeneration and ultimately nerve cell death. By targeting these pathways, buntanetap has the potential to reverse neurodegeneration in Alzheimer’s, Parkinson’s, and other neurodegenerative diseases, thereby aiming to restore brain function and improve the quality of life for patients.
