ANVS Annovis Bio Inc

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), announced today that it has received approval from the U.S. Food and Drug Administration (FDA) to transition to a new solid form of buntanetap in future clinical trials.

In June 2024, Annovis announced the filing of a composition of matter patent for the new crystal form of buntanetap and a provisional patent for the manufacturing process of this new form. The Company conducted comprehensive bridge studies in various solvents and in animals, comparing the old semi-crystalline form with the new crystalline form of buntanetap. Additionally, Annovis developed an innovative large-scale manufacturing process for the new form. This comprehensive data was submitted to the FDA for review.

The FDA has now approved the continuation of buntanetap's development using the new crystal form. This positive response allows Annovis to conduct a comparative study between the old and new forms of buntanetap in a small, single-dose, bioavailability study in humans as part of the transition process.

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 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.
