Alterity commences enrolling Multiple System Atrophy patients in bioMUSE Study

MELBOURNE,Australia and SAN FRANCISCO,Oct. 27,2020 -- Alterity Therapeutics (ASX: ATH,NASDAQ: ATHE) ("Alterity" or "the Company") today announced it has commenced enrolling patients with Multiple System Atrophy (MSA) in its bioMUSE Study in the United States.

BioMUSE is a natural history study that aims to track the progression of patients with MSA,a Parkinsonian disorder without approved therapy. The study is being conducted in collaboration with Vanderbilt University Medical Center in the US under the direction of Daniel Claassen,MD,Associate Professor of Neurology and Principal Investigator. Natural history studies are important for characterizing disease progression in selected patient populations. The study will provide vital information on early stage MSA patients to optimize the design of Alterity's Phase 2 study in MSA. The study will also inform the selection of biomarkers suitable to evaluate target engagement and preliminaryefficacy.

Dr. Claassen said: "This is an important study to expand our understanding of MSA. We are enrolling early stage patients who stand to gain the most from disease modifying treatments. I look forward to working with Alterity on this project and I hope it can provide the foundation for advancing treatments such as ATH434 into the clinic."

MSA is a neurodegenerative disease with major sources of disability resulting from motor symptoms characteristic of Parkinson's disease and impaired ability to maintain normal blood pressure,bowel functionandbladdercontrol.Currenttreatmentincludesmedicationsandlifestylechangestohelpmanage symptoms,but there is no treatment of the underlying cause and nocure.

The study is enrolling early stage MSA patients and will track changes in clinical measures and biomarkers for up to one year. Over the course of the study,patients will undergo comprehensive evaluation with detailed neurological examination and clinical rating scales of motor,autonomic and activities-of-daily- living symptoms along with specialized neuroimaging and assessment of protein biomarkers in diverse biological specimens.

Dr David Stamler,Chief Medical Officer,added: "As we prepare for our Phase 2 study,the data from bioMUSE will provide key information to help us optimize the study design. Starting this study brings us one step closer to finding novel treatments for this devastating condition."

About Alterity Therapeutics Limited and ATH434

Alterity's lead candidate,ATH434 (formerly PBT434),is the first of a new generation of small molecules designed to inhibit the aggregation of pathological proteins implicated in neurodegeneration. ATH434 has been shown to reduce abnormal accumulation of α-synuclein and tau proteins in animal models of disease by redistributing labile iron in the brain. In this way,it has potential to treat Parkinson's disease andatypicalformsofParkinsonismsuchasMultipleSystemAtrophy(MSA)andProgressiveSupranuclear Palsy(PSP).

About Multiple System Atrophy

Multiple System Atrophy (MSA) is a rare and rapidly progressive neurological disorder affecting adults. Ithasnoknowncause.InadditiontopresentingwithmotorsymptomslikethoseinParkinson'sdisease,individuals with MSA may also experience loss of ability to coordinate voluntary movements and impaired regulation of involuntary body functions such as blood pressure,bowel and bladder control. Most of these symptoms are not addressed by available drugs for patients with Parkinson's disease. As the condition progresses,daily activities become increasingly difficult and complications such as increased difficulty swallowing,vocal cord paralysis,progressive immobility,and poor balance become more prominent. Symptoms tend to appear after age 50 and rapidly advance,leading to profound disability anddeath.
