Cash balance on 30 June 2024 of A$12.6M
MELBOURNE, Australia and SAN FRANCISCO, July 31, 2024 (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 released its Appendix 4C Quarterly Cash Flow Report and update on company activities for the quarter ending 30 June 2024 (Q4 FY24).
"We have made great strides over the last two months with the positive interim data readout from our ATH434-202 Phase 2 clinical trial and the important observations from our bioMUSE Natural History Study that continue to guide development of ATH434," said David Stamler, M.D., Chief Executive Officer of Alterity. "I am very encouraged by the results from our 202 study in patients with advanced Multiple System Atrophy (MSA) where we saw favorable clinical and biomarker outcomes in some patients suggesting that ATH434 has the potential to modify the course of this devastating condition. We were also very pleased to see that the clinical responders had biomarker evidence of stable disease as this provides an objective indication of potential efficacy."
"Our bioMUSE study continues to provide valuable information to inform our patient selection criteria and choose endpoints for our Phase 2 clinical trials. This observational study has allowed us to monitor the progression of MSA in earlier stage patients and further characterize this devastating disease. Working with our colleagues at Vanderbilt University, we have employed novel MRI technology and machine learning to precisely analyze brain iron content and brain volumes in these patients over time. The results from the study have guided us to modify our endpoints in the ATH434-202 study. The data from our 202 and bioMUSE studies increases my overall confidence in the ATH434 development program," concluded Dr. Stamler.
Alterity's cash position on 30 June 2024 was A$12.6M with operating cash outflows for the quarter of A$5.6M.
In accordance with ASX Listing Rule 4.7C, payments made to related parties and their associates included in item 6.1 of the Appendix 4C incorporates directors' fees, consulting fees, remuneration and superannuation at commercial rates.
Operational Activities
ATH434–201: Randomized, Double-Blind Phase 2 Clinical Trial in Early-State MSA
On 8 May 2024, Alterity announced that an independent Data Monitoring Committee (DMC) completed its third prespecified review of unblinded clinical trial data from the ATH434-201 Phase 2 study. The DMC expressed no concerns about safety and recommended that the study continue as planned without modification. This recommendation is an important milestone as participants are able to safely tolerate ATH434 as their time on study increases.
In April 2024, important new data on ATH434 was presented at the World Orphan Drug Congress in a poster presentation, entitled, "Biophysical Characteristics of ATH434, a Unique Iron-Targeting Drug for Treating Friedreich's Ataxia." The study evaluated the ability of ATH434 to target the toxic form of iron that drives the pathology of Friedreich's Ataxia, a rare neurodegenerative disease that affects young children to young adults. The investigation provides important insights into the mechanism of action of ATH434, namely that it selectively targets the labile iron implicated in the pathology of important neurodegenerative diseases. In this way, ATH434 behaves like a chaperone to redistribute iron within the body.
In April 2024, a poster was presented at the American Academy of Neurology (AAN) 2024 Annual Meeting, entitled, "A Phase 2 Study of ATH434, a Novel Inhibitor of a-Synuclein Aggregation, for the Treatment of Multiple System Atrophy". The poster described the baseline characteristics for the 65 evaluable participants from the ATH434-201 with a focus on baseline fluid biomarkers, neuroimaging and clinical data. The participants met strict selection criteria designed to confirm they had early-stage MSA. Overall, the participants had a mean duration of motor symptoms of two years. The data showed increased iron in areas of pathology and elevated plasma Neurofilament Light Chain (NfL) levels at baseline that correlated significantly with disease severity.
The trial remains on track to complete in November 2024. The data from the trial will then be analyzed and the Company expects to report topline results by January 2025.
ATH434–202: Open-label, Biomarker Phase 2 Clinical Trial in More Advanced MSA
Subsequent to the quarter end, on 17 July 2024, Alterity reported positive interim data from the ATH434-202 trial in participants with advanced MSA. The interim analysis included clinical and biomarker data on 7 participants treated with ATH434 for 6 months and neuroimaging data on 3 participants who were treated for 12 months. After 6 months of treatment, 43% of participants showed improvement on the UMSARS1, indicating reduced disability on activities of daily living. Over the same period, 29% of participants had stable or improved neurological symptoms (clinical responders) as assessed by the global impression of change by both the treating physician and the patient. Importantly, the clinical responders on average had reduced accumulation of iron on MRI in the substantia nigra, putamen and globus pallidus and stable levels of NFL, a marker of axonal injury, when compared to participants who declined.
bioMUSE Natural History Study
On 30 May 2024 Alterity hosted a webinar to discuss data from the bioMUSE Natural History Study. The goal of the observational bioMUSE study is to optimize patient selection and choose endpoints for the Company's Phase 2 clinical trials. This study enrolled 21 individuals who were observed for 12 months to characterize early-stage MSA in terms of various biomarkers. In particular, the focus is on brain iron, brain volume, and the pathology in glial support cells. Utilizing novel MRI technology, Alterity's partners at Vanderbilt University have optimized specialized MRI methods, including machine learning (a form of artificial intelligence), to establish standardized methods to analyze brain iron and brain volumes with precision. Importantly, they developed a new, novel imaging biomarker to assess brain volume in MSA affected regions. The bioMUSE data showed a statistically significant increase in iron over 12 months in the substantia nigra, and statistically significant decreases in brain volume observed in affected regions at 12 months.
Also at AAN, a poster was presented at the AAN 2024 Annual Meeting, entitled, "Neurofilament Light Chain and Clinical Progression in Early Multiple System Atrophy". The poster described results from bioMUSE in which changes in clinical severity of 15 patients across a span of 12 months were compared with plasma biomarkers with a goal of establishing meaningful correlations. Importantly, the observational data suggest the fluid biomarker NfL may be used as a marker of disease severity in studies of MSA as it holds promise for measuring the extent of disease, tracking its progression, and forecasting the onset of clinical manifestations associated with MSA.
ATH434 for the Treatment of Parkinson's Disease
A poster was also presented at AAN entitled, "Effects of ATH434, a Clinical-Phase Small Molecule with Moderate Affinity for Iron, in Hemiparkinsonian Macaques". The presentation showed that ATH434 can reduce Parkinsonism in a higher order animal, the monkey, with symptoms that closely parallel human disease. Importantly, the improvements in motor skills and general functioning that parallel human parkinsonism were associated with reductions in abnormal iron in affected brain regions. These favorable parkinsonian outcomes observed in the ATH434-treated monkeys were also associated with increased levels of striatal synaptophysin, a protein marker that reflects functional connections between neurons, suggesting functional recovery of nerve endings in this critical motor pathway. Taken together, the findings in this study increase the Company's confidence in their approach in the ongoing Phase 2 program in MSA.
