MELBOURNE,Australia and SAN FRANCISCO,Jan. 6,2022 -- Alterity Therapeutics (ASX: ATH,NASDAQ: ATHE) ("Alterity" or "the Company"),a biotechnology company dedicated to developing disease modifying treatments for neurodegenerative diseases,today announced the United States Patent and Trademark Office (USPTO) has granted a new patent (No. 11,155,547) to Alterity.

The composition of matter patent,entitled "Compounds for and Methods of Treating Diseases",underwent prioritized examination by the USPTO.The patent covers more than80 novel compounds and secures exclusivity for a new class of iron chaperones designed to redistribute the excess iron implicated in many neurodegenerative diseases,including Parkinson's disease and Alzheimer's disease.

"We continue to identify new drug candidates to expand our portfolio and protect our therapeutic approach to address neurodegeneration," said David Stamler,M.D.,Chief Executive Officer,Alterity. "With the granting of this patent and another composition of matter patent last year,we are establishing a strong foundation as a leader in targeting iron for potential disease modifying therapy for important neurodegenerative diseases such as Parkinson's and Alzheimer's."

The patent will provide Alterity with exclusivity over the compounds claimed in the patent through 2041,thus providing a strong basis for drug development and commercialization in major neurodegenerative diseases.

In addition to the US,the company is pursuing patent protection in other jurisdictions.

About Parkinson's Disease

Parkinson's disease (PD) belongs to a group of conditions called motor system disorders,which cause unintended or uncontrollable movements of the body.The precise cause of PD is unknown,but some cases are hereditary while others are thought to occur from a combination of genetics and environmental factors that trigger the disease.In PD,brain cells become damaged or die in the part of the brain that produces dopamine--a chemical needed to produce smooth,purposeful movement. The four primary symptoms of PD are tremors,rigidity,slowing of spontaneous and automatic movement,and impaired balance. Other symptoms may include difficulty swallowing,chewing,or speaking; emotional changes; urinary problems or constipation; dementia or other cognitive problems; fatigue; and problems sleeping.[1]Nearlyone million people in the U.S. and more than 10 million people worldwide are living with PD. Approximately 60,000 Americans are diagnosed with PD each year.[2]

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.[3]
