MELBOURNE, Australia and SAN FRANCISCO, Aug. 12, 2026 (GLOBE NEWSWIRE) — Alterity Therapeutics<\/a> (ASX: ATH, NASDAQ: ATHE) (\u201cAlterity\u201d or \u201cthe Company\u201d), a biotechnology company dedicated to developing disease modifying treatments for neurodegenerative diseases, today announced that the United States Patent and Trademark Office (USPTO) has granted a new composition of matter patent for ATH434, the Company\u2019s lead clinical asset. ATH434 is an oral agent designed to treat the underlying pathology of neurodegenerative diseases such as Multiple System Atrophy (MSA), Parkinson\u2019s disease and related disorders. The newly granted patent represents a significant intellectual property milestone for Alterity and strengthens ATH434\u2019s long-term commercial potential as the Company prepares to initiate Phase 3 trial activities in MSA by year-end 2026.<\/p>\n

The new patent provides composition-of-matter protection for a crystalline structure of the mesylate salt form of ATH434 as well as protection for methods for treating neurological conditions using it. This form of ATH434 was used in the Company\u2019s Phase 2 clinical trials in MSA and will be utilized in the planned Phase 3 study. The patent extends protection for ATH434 to at least 2045, and together with existing intellectual property (IP) and regulatory designations, provides multi-layered market protection. In addition to reinforcing Alterity\u2019s position in MSA, the new patent enables future development opportunities for ATH434 in Parkinson\u2019s disease and other neurodegenerative diseases where iron dysregulation and protein aggregation are implicated.<\/p>\n

\u201cWith protection to at least 2045, this patent extends the commercial life and revenue potential for ATH434 in MSA, if approved, as we prepare to initiate Phase 3 trial activities by year-end 2026,\u201d said David Stamler, M.D., Chief Executive Officer. \u201cImportantly, Parkinson\u2019s disease is now a viable target indication for ATH434, as our strengthened IP provides the protection needed to justify investment in this major neurodegenerative disorder. The granting of this new U.S. composition of matter patent reflects the deliberate execution of our IP strategy and is one of the most critical steps we have taken to protect the innovation behind ATH434.\u201d<\/p>\n

\u201cOverall, this patent enhances the strategic value of ATH434, supporting potential partnerships and other opportunities to advance development. We remain dedicated to developing ATH434 as a disease modifying treatment for these debilitating conditions,\u201d concluded Dr. Stamler.<\/p>\n

\n New Composition of Matter Patent for ATH434<\/strong>\n <\/p>\n

The USPTO granted the patent entitled “Crystalline Form, and Process for its Production” which covers the composition of matter of a crystalline form of ATH434 mesylate as well as methods for treating neurological conditions using it. The allowed claims protect the novel solid-state crystalline form of ATH434 mesylate and treatment methods, providing another layer of protection as a commercial asset for the treatment of MSA and additional neurodegenerative diseases.<\/p>\n

The patent has an estimated expiration date of at least 2045 and is expected to be listed in the FDA\u2019s Approved Drug Products with Therapeutic Equivalence Evaluations <\/em>publication (the \u201cOrange Book\u201d), upon regulatory approval of ATH434 for commercialization.<\/p>\n

Composition of matter claims are widely recognized as one of the strongest forms of pharmaceutical patent protection.<\/p>\n

\n About ATH434<\/strong>\n <\/p>\n

Alterity\u2019s lead candidate, ATH434, is an oral agent designed to reduce iron accumulation and inhibit abnormal protein aggregation associated with neurodegeneration. ATH434 has been shown to reduce \u03b1-synuclein pathology and preserve neuronal function by restoring normal iron balance in the brain in preclinical models. With properties shared by endogenous iron chaperones, it has the potential to treat Parkinson\u2019s disease as well as various Parkinsonian disorders such as Multiple System Atrophy (MSA). Positive results from the randomized, double-blind, placebo-controlled Phase 2 clinical trial in patients with MSA demonstrated clinically meaningful efficacy, target engagement as indicated by key biomarkers, and a favorable safety profile. Positive data from a second Phase 2 open-label biomarker trial in patients with more advanced MSA reinforced these results. ATH434 has been granted Fast Track Designation by the U.S. Food and Drug Administration (FDA), and Orphan Drug Designation by the FDA and the European Commission for the treatment of MSA.<\/p>\n

\n About Multiple System Atrophy<\/strong>\n <\/p>\n

Multiple System Atrophy (MSA) is a rare, neurodegenerative disease characterized by failure of the autonomic nervous system and impaired movement. The symptoms reflect the progressive loss of function and death of different types of nerve cells in the brain and spinal cord. It is a rapidly progressive disease that causes profound disability. MSA is a Parkinsonian disorder characterized by a variable combination of slowed movement and\/or rigidity, autonomic dysfunction affecting involuntary functions such as blood pressure maintenance and bladder control, and impaired balance and\/or coordination that predispose patients to falls. A pathological hallmark of MSA is the accumulation of abnormal clumping of the protein \u03b1-synuclein within oligodendrocytes, the myelin-producing support cells of the central nervous system, along with progressive neuronal loss in multiple brain regions. MSA affects up to 50,000 individuals in the U.S., and while some of the symptoms of MSA can be treated with medications, currently there are no drugs that are able to slow disease progression and there is no cure.1<\/sup><\/p>\n

\n About Parkinson\u2019s Disease<\/strong>\n <\/p>\n

Parkinson’s disease (PD) is the second most common neurodegenerative disorder and causes unintended or uncontrollable movements of the body along with neuropsychiatric and other nonmotor features.\u00a0The 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.\u00a0In PD, brain cells become damaged or die in the substantia nigra, the part of the brain that produces dopamine \u2013 a chemical needed to produce smooth, purposeful movement. The cardinal symptoms of PD are tremors, rigidity, slowing of movements, and later in disease, 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.2<\/sup> Nearly\u00a0one 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.3<\/sup><\/p>\n
