Importantly, we observed that significant reductions in brain volume over 12 months correlated with clinical worsening of the disease. The results underscore the importance of utilizing advanced neuroimaging and analytical methods in evaluating MSA which we have implemented in our Phase 2 clinical trials.”\nThe platform presentation entitled, “The MSA Atrophy Index: A Marker of Clinical Progression in Multiple System Atrophy”, was presented by Paula Trujillo Diaz, PhD, Research Assistant Professor, Department of Neurology, Vanderbilt University Medical Center.\nWhile previous MRI studies have reported brain volume reductions in regions implicated in MSA, tracking these changes reliably has been challenging. In this study, machine learning tools were used to precisely define the neuroanatomy and a specific brain atrophy measure was designed to track disease progression in MSA patients over one year. The results were then correlated with clinical measures of disease progression. The poster introduces the MSA Atrophy Index (MSA-AI), a composite atrophy marker derived from the lentiform nucleus (LN, putamen and globus pallidus) and olivopontocerebellar (OPC, cerebellum and brainstem) regions, as a potential biomarker for assessing MSA progression. These methods can enhance the understanding of MSA progression and provide support for using brain atrophy markers for the evaluation of disease-modifying therapies.\nAbout bioMUSE\nBiomarkers of progression in Multiple System Atrophy (bioMUSE) is a natural history study that aims to track the progression of individuals 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, M.D., M.S., 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 randomized ATH434-201 Phase 2 clinical trial and enrolled approximately 20 individuals with clinically probable or clinically established MSA. BioMUSE continues to provide vital information on early stage MSA patients, informs the selection of biomarkers suitable to evaluate target engagement and preliminary efficacy, and delivers clinical data to characterize disease progression in a patient population that mirrors those currently enrolling in the Phase 2 clinical trial. \nAbout Multiple System Atrophy\nMultiple 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 at least 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\n1Multiple System Atrophy | National Institute of Neurological Disorders and Stroke (nih.gov)\nAbout Parkinson’s Disease\nParkinson's disease (PD) is the second most common neurodegenerative disorder and causes unintended or uncontrollable movements of the body along with neuropsychiatric and other nonmotor features. The precise cause of PD is unknown, but some cases are hereditary while others are thought to occur from a combination of genetics and environmental factors that trigger the disease. In PD, brain cells become damaged or die in the substantia nigra, the part of the brain that produces dopamine--a chemical needed to produce smooth, purposeful movement. The cardinal symptoms of PD are tremors, rigidity, slowing of movements, and later in disease, impaired balance. Other symptoms may include difficulty swallowing, chewing, or speaking; emotional changes; urinary problems or constipation; dementia or other cognitive problems; fatigue; and problems sleeping.2 Nearly one million people in the U.S. and more than 10 million people worldwide are living with PD. Approximately 60,000 Americans are diagnosed with PD each year.3\n2National Institute of Health: Neurological Disorders and Stroke, Parkinson's Disease Information Page; 3Parkinson’s Foundation\nAbout Alzheimer’s Disease\nAlzheimer's disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die. Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral, and social skills that affects a person's ability to function independently. Approximately 5.8 million people in the United States age 65 and older live with Alzheimer's disease. Of those, 80% are 75 years old and older. Out of the approximately 50 million people worldwide with dementia, between 60% and 70% are estimated to have Alzheimer's disease. Medications may temporarily improve or slow progression of symptoms, but there is no treatment that cures Alzheimer's disease or alters the disease process in the brain. In advanced stages of the disease, complications from severe loss of brain function, such as dehydration, malnutrition or infection, result in death.\nAbout Alterity Therapeutics Limited \nAlterity Therapeutics is a clinical stage biotechnology company dedicated to creating an alternate future for people living with neurodegenerative diseases.
