Alterity Therapeutics Presents Promising Wearable Sensor Data from the bioMUSE Natural History Study at the American Academy of Neurology
Alterity Therapeutics (ASX: ATH, NASDAQ: ATHE) announced findings from the bioMUSE study at the American Academy of Neurology Annual Meeting, showcasing wearable sensors' effectiveness in quantifying motor impairment in patients with Multiple System Atrophy (MSA). The analysis involved 17 participants and indicated a strong correlation between sensor parameters and traditional clinical assessments of motor impairment. This data is significant for future clinical trials, as wearable sensors will be integrated as secondary endpoints in the ongoing Phase 2 trial of ATH434. ATH434 aims to address neurodegeneration and has shown promise in preclinical studies. The ongoing research is pivotal for understanding MSA's progression and optimizing treatment methods.
- Strong correlation found between wearable sensor data and clinical scales of motor impairment.
- Integration of wearable sensor analysis into Phase 2 clinical trial for ATH434.
- ATH434 has shown preclinical success in reducing α-synuclein pathology.

Wearable sensor parameters correlate strongly with clinical scales of motor impairment
MELBOURNE, Australia and SAN FRANCISCO, April 26, 2023 (GLOBE NEWSWIRE) -- 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 promising wearable sensor data from the Biomarkers of Progression in Multiple System Atrophy (bioMUSE) natural history study was presented at the American Academy of Neurology Annual Meeting.
The poster, entitled, Wearable Sensors for Quantitative Motor Assessments in Multiple System Atrophy, was presented by Daniel Claassen, MD, Professor of Neurology at Vanderbilt University Medical Center, and Principal Investigator in the bioMUSE study. The analysis was conducted to determine the utility of quantitative wearable sensors in 17 participants with early stage (less than three years of motor symptoms) multiple system atrophy (MSA).
“This analysis from bioMUSE demonstrates that wearable sensors can quantify motor impairment in MSA patients that is not captured by neurological examination,” said David Stamler, M.D., Chief Executive Officer, Alterity. “MSA is a devastating condition and use of novel measures to assess disease progression and inform future clinical trials is a win for the entire community. As a result of this natural history study, we have incorporated wearable sensor data into our Phase 2 clinical trial for ATH434 as one of our secondary endpoints to determine the effect of our agent on gait stability. We look forward to additional data from bioMUSE as we strive to better understand the trajectory of MSA and utilize our findings in future clinical trials.”
In the study, a strong relationship was evident between sensor parameters and motor assessments. Specifically, sensor parameters correlated strongly with clinical scales of motor impairment and may be useful in assessing disease progression. Importantly, an assessment known as the Timed Up and Go strongly correlated with several gait parameters, including bouts of walking, minutes walking, minutes of standing, and minutes of lying. Because the Timed Up and Go reliably quantifies functional mobility in a clinic setting, the new data suggesting the clinical relevance of these outcomes is important in assessing MSA in the outpatient setting. The results from bioMUSE will inform future trials in MSA as potential outcome measures for disease modifying therapies.

About bioMUSE
Biomarkers of progression in Multiple System Atrophy (bioMUSE) is an ongoing, 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 U.S. 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 has provided rich data for optimizing the design of Alterity’s Phase 2 clinical trial and will be expanded to include a total of 20 patients with MSA. The ongoing study will continue to provide vital information on early stage MSA patients, inform the selection of biomarkers suitable to evaluate target engagement and preliminary efficacy, and deliver clinical data to characterize disease progression in a patient population that mirrors those to be enrolled in the Phase 2 clinical trial.
About Multiple System Atrophy
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 and causes profound disability. MSA is a Parkinsonian disorder characterized by a variable combination of slowed movement and/or rigidity, autonomic instability that affects involuntary functions such as blood pressure maintenance and bladder control, and impaired balance and/or coordination that predisposes to falls. A pathological hallmark of MSA is the accumulation of the protein α-synuclein within glia, the support cells of the central nervous system, and neuron loss in multiple brain regions. MSA affects approximately 15,000 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

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 nerve cells 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 is currently being studied in a randomized, double-blind, placebo-controlled Phase 2 clinical trial in patients with early-stage MSA. ATH434 has been granted Orphan designation for the treatment of MSA by the U.S. FDA and the European Commission.
About ATH434 Phase 2 Clinical Trial
The Phase 2 clinical trial is a randomized, double-blind, placebo-controlled investigation of ATH434 in patients with early-stage MSA. The study will evaluate the effect of ATH434 treatment on neuroimaging and protein biomarkers to demonstrate target engagement and clinical endpoints to demonstrate efficacy, in addition to assessments of safety and pharmacokinetics. The selected biomarkers, including brain iron and aggregating α-synuclein, are important contributors to MSA pathology and are therefore appropriate targets to demonstrate drug activity. Wearable sensors will also be employed to evaluate motor activities that are important to patients with MSA. The study is expected to enroll approximately 60 adults to receive one of two dose levels of ATH434 or placebo. Participants will receive treatment for 12 months which will provide an opportunity to detect changes in efficacy endpoints to optimize design of a definitive Phase 3 study. Additional information on the Phase 2 trial can be found by ClinicalTrials.gov Identifier: NCT05109091.
