Alterity ATH434 Prevents Loss of Brain Cells in Parkinson’s Disease Animal Model

 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 a study recently published in the journal Neurotherapeutics demonstrated that its lead clinical asset, ATH434, was neuroprotective in a genetic model of Parkinson’s disease (PD). Parkinson’s is a progressive neurodegenerative disorder that causes slow or abnormal movements of the body and non-motor features that contribute significantly to morbidity and reduced quality of life.

The publication, entitled “ATH434 Rescues Pre‑motor Hyposmia in a Mouse Model of Parkinsonism” assessed the impact of ATH434 on motor and non-motor deficits in mice with genetically induced Parkinson’s disease1. Hyposmia, defined as reduced sensitivity to odor, is an early and common non-motor symptom of PD that precedes the typical motor symptoms by several years, occurring in approximately 90% of early-stage cases of PD2.

The study found that ATH434 prevented a loss of smell in the younger mice and rescued it in older mice. More importantly, the authors also demonstrated that ATH434 prevented the development of motor impairment in older animals, which was associated with a reduction in iron levels and preservation of neurons in the substantia nigra, the brain region affected in Parkinson’s. These data support other studies indicating that ATH434 has a beneficial effect on the motor and non-motor symptoms in animal models of PD.
