Alterity Therapeutics Announces Completion ofPlacement


MELBOURNE, AUSTRALIA AND SAN FRANCISCO, USA– 7 April 2025: Alterity Therapeutics (ASX: ATH, NASDAQ: ATHE) (“Alterity” or “the Company”), a biotechnology company dedicated to developing disease modifying treatments for neurodegenerative diseases, today announced completion of the second tranche of the two-tranche placement initiated earlier this year.   Overall A$38.79M of funds were received with participation from Alterity’s CEO and CFO and the majority of the Board of Directors.

David Stamler, M.D., Chief Executive Officer of Alterity, commented, “We are grateful for the strong shareholder support at our Extraordinary General Meeting last week to complete our Placement, giving us the runway to continue to advance our pipeline focused on neurodegenerative diseases. We expect to use the funds from this capital raise to accelerate the regulatory and development activities for ATH434 and to continue research and discovery of novel compounds for major indications such as Parkinson’s disease.”

About ATH434


Alterity’s lead candidate, ATH434, is an oral agent designed to inhibit the aggregation of pathological proteins implicated in neurodegeneration. ATH434 has been shown preclinically to reduce α-synuclein pathology and preserve neuronal function by restoring normal iron balance in the brain. As an iron chaperone, it has excellent potential to treat Parkinson’s disease as well as various Parkinsonian disorders such as Multiple System Atrophy (MSA). ATH434 successfully completed Phase 1 studies demonstrating the agent is well tolerated and achieved brain levels comparable to efficacious levels in animal models of MSA. ATH434 recently announced positive results from the randomized, double-blind, placebo-controlled Phase 2 clinical trial in patients with MSA. A second Phase 2 open-label 2 Biomarker trial in patients with advanced MSA is ongoing. ATH434 has been granted Orphan Drug Designation for the treatment of MSA by the U.S. FDA and the European Commission.
