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 neuronal
function 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 two clinical trials: Study ATH434-201 is
a randomized, double-blind, placebo-controlled Phase 2 clinical
trial in patients with early-stage MSA and Study ATH434-202 is an
open-label Phase 2 Biomarker trial in patients with more advanced
MSA. ATH434 has been granted Orphan drug designation for the
treatment of MSA by the U.S. FDA and the European Commission.
About ATH434-201 Phase 2 Clinical
Trial
The ATH434-201 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. Selected biomarkers, such as brain iron and
aggregating α-synuclein, are important contributors to MSA
pathology and are therefore appropriate targets to demonstrate drug
activity. Wearable sensors have also been employed to evaluate
motor activities that are important to patients with MSA. The study
enrolled 77 adults who were randomly assigned 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.
About bioMUSE
Biomarkers 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.
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 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

About Parkinson’s Disease
Parkinson'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
