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.
Alterity Therapeutics (NASDAQ: ATHE) has secured binding commitments for a A$40.0 million capital raise through a two-tranche placement of ordinary shares to institutional and sophisticated investors.
