• Composition of matter patent from USPTO covers more than 100 novel compounds targeting neurodegenerative diseases including Alzheimer’s 
  
• Newly patented compounds and legacy asset PBT2 licensed to Professor Colin Masters for evaluation in Alzheimer’s and related diseases 

MELBOURNE, Australia AND SAN FRANCISCO, March 14, 2023 (GLOBE NEWSWIRE) -- Alterity Therapeutics (ASX: ATH, NASDAQ: ATHE) (“Alterity” or “the Company”), a biotechnology company dedicated to developing disease modifying treatments for neurodegenerative diseases, today announced that the composition of matter patent previously allowed by the United States Patent and Trademark Office (USPTO) has now been granted. The patent, entitled “Compounds for and methods of treating diseases” (No. 11,603,364), covers more than 100 novel compounds with an acyl hydrazone (AH) structure and provides 20 years of exclusivity.

Alterity also announced a Licensing Agreement for the new patent and a sub-licensing agreement for PBT2 to Professor Colin Masters, M.D., A.O., to advance these compounds for the treatment of Alzheimer’s and related diseases. Under the license agreement, Alterity grants the entire rights to the AH patent as well as an exclusive worldwide license to develop and commercialize both AH and PBT2 in Alzheimer’s disease (AD). In exchange, Alterity is entitled to future royalties of net sales from the assets.

Professor Masters is a preeminent researcher in the field of Alzheimer’s disease whose work characterizing the beta amyloid protein (Aβ amyloid) that forms the cerebral plaques in AD has laid the foundation for recently approved treatments for this neurodegenerative disease. He has received numerous awards and recognition for his research, including the Order of Australia (A.O.) which recognizes Australians who have demonstrated exceptional achievement, and a Lifetime Achievement Award in Alzheimer's Disease Research from the Alzheimer's Association.

“This new patent is a testament to the ongoing success of our discovery team as they continue to generate novel small molecules with potential to treat important neurodegenerative diseases,” said David Stamler, M.D., Chief Executive Officer, Alterity. “We are excited to extend our long-standing collaboration with Professor Masters, whose understanding of the role of beta amyloid in Alzheimer’s disease pathogenesis and research cannot be overstated. Because the AH compounds act similarly to PBT2, this deal makes good sense for future research and development to occur alongside one another. This arrangement broadens the opportunity for both programs since our clinical development efforts are currently focused on Parkinsonian disorders such as Multiple System Atrophy and Parkinson’s disease.”

Professor Masters, added, “Our research teams are excited for the opportunity to advance PBT2 and the compounds associated with the AH patent. We look forward to continued collaborations with Alterity as we look to add value to existing patents and find ways to develop novel Alzheimer’s disease-modifying therapeutics using the latest technologies employing imaging and biofluid biomarkers.”

The acyl hydrazone patent is based on a new scaffold that is distinct from those specified in recent patents granted to Alterity and includes more than 100 novel small molecules, at least one of which has demonstrated efficacy in an animal model of dementia.

PBT2 is a low molecular weight drug candidate discovered by Alterity and is currently the Company’s product candidate for Alzheimer’s disease. It is orally bioavailable, crosses the blood-brain barrier, and was found to be safe and well tolerated in clinical trials in healthy volunteers and patients. PBT2 has demonstrated efficacy in individuals with Alzheimer’s disease.

About Alzheimer’s Disease

Alzheimer's disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die. Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral, and social skills that affects a person's ability to function independently. Approximately 5.8 million people in the United States age 65 and older live with Alzheimer's disease. Of those, 80% are 75 years old and older. Out of the approximately 50 million people worldwide with dementia, between 60% and 70% are estimated to have Alzheimer's disease. Medications may temporarily improve or slow progression of symptoms, but there is no treatment that cures Alzheimer's disease or alters the disease process in the brain. In advanced stages of the disease, complications from severe loss of brain function, such as dehydration, malnutrition or infection, result in death.¹
