  • The invention relates to a method of treating prion diseases, a family of ultra-rare progressive neurodegenerative disorders, by administering buntanetap. There is additional coverage for certain prion diseases, including scrapie prion, transmissible mink encephalopathy (TME), chronic wasting disease (CWD), bovine spongiform encephalopathy (BSE) prion, feline spongiform encephalopathy (FSE), exotic ungulate encephalopathy (EUE), kuru prion, Creutzfeldt-Jakob disease (CJD), variant Creutzfeldt-Jakob disease (vCJD, nvCJD), Gerst-mann syndrome -Straussler-Scheinker (GSS) and Fatal Familial Insomnia (IFF) prion.


About Buntanetap


Buntanetap (formerly known as ANVS401 or Posiphen) is an oral translation inhibitor of neurotoxic aggregating proteins (TINAPs), whose mode of action leads to a lower level of neurotoxic proteins and consequently less toxicity in the brain. In a phase 2a clinical trial in patients with AD and PD, buntanetap was shown to be well tolerated and safe, and its pharmacokinetics were consistent with levels previously measured in humans, satisfying both primary and secondary endpoints. Additionally, exploratory endpoints were also met, as buntanetap treatment resulted in statistically significant improvement in motor function in patients with PD and cognition in patients with AD. Currently, buntanetap is in a Phase 3 study in early PD and will enter a Phase 2/3 study in patients with AD later this year.
