Alterity Therapeutics (NASDAQ: ATHE) has announced the publication of a groundbreaking study in the Annals of Clinical and Translational Neurology, introducing the MSA Atrophy Index (MSA-AI), a novel MRI-based measurement tool for Multiple System Atrophy (MSA).
The research, developed through Alterity's bioMUSE Natural History Study, employs deep learning methods to track brain atrophy in MSA patients. The study demonstrated that MSA-AI can effectively distinguish MSA from related conditions like Parkinson's disease and Dementia with Lewy Bodies, with significantly lower scores indicating reduced brain volumes in MSA patients (p < 0.001).
Importantly, the study revealed that 12-month brain volume reductions correlated with clinical disease worsening. This innovative tool will be implemented in Alterity's Phase 2 clinical program and future Phase 3 trials for patient selection and disease progression monitoring.
Alterity Therapeutics (NASDAQ: ATHE) presented significant findings at the 2025 International MSA Congress regarding their ATH434 Phase 2 clinical trial and related MSA research. The ATH434-201 trial demonstrated promising results, with the 50mg dose showing a 48% relative treatment effect (p=0.02) and the 75mg dose showing a 30% effect (p=0.16) in reducing disease severity on the UMSARS I scale. The drug was well-tolerated with no serious adverse events.
Key research presentations included the development of the MSA Atrophy Index (MSAai), a new imaging biomarker for improved MSA diagnosis and monitoring, and findings from the bioMUSE Natural History Study showing increased α-synuclein levels in skin correlating with greater orthostatic symptoms. The study also demonstrated ATH434's ability to stabilize or reduce iron accumulation in affected brain regions and showed trends in reducing brain atrophy at both dose levels.
Alterity Therapeutics (NASDAQ: ATHE) has received Fast Track designation from the FDA for its drug candidate ATH434 in treating Multiple System Atrophy (MSA). This designation, complementing their existing Orphan Drug Designation, aims to accelerate the development and review process for ATH434, recognizing its potential as an innovative treatment for MSA - a condition currently without approved therapies.
CEO David Stamler highlighted that the Fast Track status validates ATH434's promise, supported by recent scientific findings on its mechanism of action and positive results from their double-blind Phase 2 clinical trial. The designation enables more frequent FDA interactions, potentially expediting the drug's development and approval pathway.
Alterity Therapeutics reported positive results from its ATH434-201 Phase 2 clinical trial for Multiple System Atrophy (MSA) treatment. The trial demonstrated a significant 48% reduction in disease severity at 50mg dose and 30% at 75mg dose compared to placebo.
Key financial highlights include a cash balance of A$17.96M as of March 31, 2025, with an additional A$27.1M raised after the quarter end. Operating cash outflows were A$0.73M for Q3 FY25.
The company completed its ATH434-202 open-label trial in advanced MSA patients in March 2025, with topline data expected mid-year. The drug showed positive results in clinical efficacy, including improvements in daily living activities, severity assessment, and increased patient activity levels measured by wearable sensors. ATH434 was well-tolerated with no serious adverse events attributed to the treatment.
Alterity Therapeutics (NASDAQ: ATHE) presented Phase 2 clinical trial results for ATH434-201 at the MSA Research Symposium. The double-blind study, involving 71 patients, demonstrated significant efficacy in treating Multiple System Atrophy (MSA).
Key findings include:
- 48% relative treatment effect at 50mg dose (p=0.02) and 30% at 75mg dose (p=0.16) on UMSARS I scale
- Improvement in Clinical Global Impression of Severity Scale at both doses
- Enhanced patient mobility metrics including step count and walking time
- Positive results in reducing brain atrophy and stabilizing iron levels in affected brain regions
The treatment was well-tolerated with similar adverse event rates to placebo, with no serious adverse events attributed to ATH434. The strong clinical efficacy data and novel mechanism support continued advancement of ATH434 for MSA treatment.
Alterity Therapeutics (NASDAQ: ATHE) has presented new data from its ATH434 Phase 2 trial for Multiple System Atrophy (MSA) at the American Academy of Neurology 2025 Annual Meeting. The double-blind study showed promising results with clinically meaningful efficacy across multiple measures.
Key findings include:
- 48% decrease in clinical progression at 50mg dose (p=0.02) and 30% decrease at 75mg dose using modified UMSARS I rating scale
- Improvement in Clinical Global Impression of Severity Scale at 50mg dose (p=0.0088)
- Positive trends in Orthostatic Hypotension Symptom Assessment
- Increased activity levels measured by wearable sensors, including improved step count, walking time, and standing time
The imaging outcomes in 61 participants demonstrated that ATH434 reduces iron signal in MSA-affected brain regions. Additionally, results from the bioMUSE natural history study supported the utility of wearable sensors in MSA trials, showing correlations between sensor-derived metrics and clinical evaluations.
Alterity Therapeutics (NASDAQ: ATHE) has announced upcoming presentations of its ATH434 Phase 2 clinical trial results for Multiple System Atrophy (MSA) at the American Academy of Neurology Annual Meeting in San Diego (April 5-9, 2025).
The presentations include an oral session featuring topline data from the randomized, double-blind, placebo-controlled Phase 2 study, to be presented by Dr. Daniel Claassen from Vanderbilt University Medical Center. Additionally, a poster presentation will discuss wearable sensor data correlation with clinical scores in early-stage MSA patients.
ATH434 is an oral agent designed to inhibit pathological protein aggregation in neurodegeneration by restoring brain iron balance. The drug has received Orphan Drug Designation for MSA treatment from both the FDA and European Commission. Besides the completed Phase 2 trial showing positive results, a second Phase 2 open-label biomarker trial in advanced MSA patients is currently ongoing.
Alterity Therapeutics (NASDAQ: ATHE) has announced the completion of the last patient visit in its ATH434-202 Phase 2 open-label trial for Multiple System Atrophy (MSA). The study aims to evaluate the safety, efficacy, and target engagement of ATH434, a disease-modifying drug candidate for neurodegenerative diseases, specifically in patients with advanced MSA.
Following positive results from their previous randomized, double-blind Phase 2 trial, this open-label study focuses on a population with advanced-stage illness. The company expects to report topline data by mid-year 2025. CEO David Stamler emphasized that the data will help guide their development program, noting the differences between this study and the double-blind trial.
