What Alterity Therapeutics does

Alterity Therapeutics Ltd. is an Australian company, incorporated on November 11, 1997, that develops first-in-class therapies for neurodegenerative diseases.

Its lead drug candidate, ATH434, is an oral iron chaperone that has been shown in preclinical animal studies to reduce the accumulation and aggregation of alpha-synuclein. Its clinical development program is focused on multiple system atrophy (MSA), a rare Parkinsonian disorder with no approved treatments. The company has also conducted a Natural History Study in MSA and has a preclinical program in Parkinson's disease. Its chemical library includes more than 1000 novel compounds. The company also describes next generation zinc ionophores, invented in 2021, that may modulate zinc for diseases such as cancer, neurological diseases and infectious diseases. Its chemistry program is undertaken within laboratories leased from The University of Melbourne's Bio21 Molecular Science and Biotechnology Institute.
