Alterity Therapeutics Doses First Patient in ATH434 Phase 2 Clinical Trial in Multiple System Atrophy

2022-07-06 23:00 1574

MELBOURNE, Australia and SAN FRANCISCO, July 6, 2022 /PRNewswire/ -- Alterity Therapeutics (ASX: ATH, NASDAQ: ATHE) ("Alterity" or "the Company"), a biotechnology company dedicated to developing disease modifying treatments for neurodegenerative diseases, today announced the first patient has been dosed in the Company's Phase 2 clinical trial of ATH434 in Multiple System Atrophy (MSA), a rare and highly debilitating Parkinsonian disorder.

While it is similar to Parkinson's disease, MSA progresses more rapidly and causes profound disability. In addition to the motor symptoms characteristic of Parkinson's disease, MSA manifests with more severe autonomic nervous system impairment resulting in bladder dysfunction and the inability to maintain normal blood pressure, as well as uncoordinated or clumsy movements that contribute to falling. There are no known causes or specific risk factors associated with the disease.

"Dosing of our first patient is a significant milestone for Alterity as we look to bring a potential new treatment option to individuals living with MSA," said David Stamler, M.D., Chief Executive Officer, Alterity. "This is just the first step as we expect to expand enrolment in multiple regions over the second half of this year. We are grateful to the entire clinical team at the New Zealand Brain Research Institute whose efficiency and dedication to their patients supported this accomplishment."

"As a clinician looking after people with MSA, I'm very pleased that Alterity has chosen to bring this clinical trial of a novel prospective therapy to New Zealand. There is presently no available treatment to slow down or prevent progression of this distressing brain disorder so trials such as this are very welcome," added Professor Tim Anderson, Lead Investigator of the trial at the New Zealand Brain Research Institute.

The Phase 2 clinical trial is a randomized, double-blind, placebo-controlled investigation of ATH434 in patients with early-stage MSA. The study will explore the effect of ATH434 treatment on imaging and protein biomarkers, such as aggregating α-synuclein and excess iron, which are important contributors to MSA pathology. Clinical and biomarker endpoints will permit comprehensive assessment of ATH434 efficacy along with characterization of safety and pharmacokinetics. The study is expected to enroll approximately 60 adult patients to receive one of two doses of ATH434 or placebo. Patients 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.

About ATH434

Alterity's lead candidate, ATH434, 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 preclinically to reduce α-synuclein pathology and preserve nerve cells by restoring normal iron balance in the brain. In this way, it has excellent potential to treat Parkinson's disease as well as various forms of atypical Parkinsonism such as Multiple System Atrophy (MSA). ATH434 has successfully completed a Phase 1 clinical trial demonstrating the agent is well tolerated, orally bioavailable, and achieved brain levels comparable to efficacious levels in animal models of MSA, with the objective of restoring function in patients with MSA and other Parkinsonian disorders.

ATH434 has been granted Orphan designation for the treatment of MSA by the U.S. FDA and the European Commission.

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]
