Alterity Therapeutics Announces New US Patent to Expand its Portfolio of Compounds for Neurodegenerative Diseases including Alzheimer's and Parkinson's

MELBOURNE,Australia,Aug. 4,2021 -- Alterity Therapeutics (ASX: ATH,NASDAQ: ATHE) ("Alterity" or "the Company"),a biotechnology company dedicated to developing disease modifying treatments for neurodegenerative conditions,today announced the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for Alterity's patent application No.17/239,375. The composition of matter patent secures exclusivity for a new group of iron chaperones designed to redistribute the excess iron implicated in many neurodegenerative diseases,including Alzheimer's and Parkinson's.

The patent,entitled "Compounds for and Methods of Treating Diseases",covers more than80 novel compounds and underwent prioritized examination by the USPTO.Together with the recent grant of Alterity's US patent No. 10,941,143 for claims on a separate group of more than 150 novel compounds,Alterity is in a strong position with respect to its iron chaperone technology to address neurodegeneration. This position was further exemplified by the absence of any novelty or inventiveness objections during the course of prosecution.

"As the scientific evidence implicating excess brain iron in neurodegeneration accumlates,our in-house research team continues to discover novel compounds that address this important target," said Alterity Chief Executive Officer David Stamler,M.D. "The structural backbone illustrated in this new patent provides a larger foundation for small molecule drug candidates to attack this source of neuropathology. As we advance our lead clinical asset ATH434 into a Phase 2 clinical trial later this year,we look forward to identifying new drug candidates to add to our pipeline and address several critical diseases."

The notice of allowance means that the USPTO would issue the patent after certain administrative steps have been completed.The patent will confer onAlterity approximately 20 years of exclusivity over the the compounds claimed in the patent,thus providing a strong basis for drug development and commercialization in neurodegenerative diseases including the Company's first indication Multiple System Atrophy as well as Parkinson's Disease and Alzheimer's Disease.
