Alterity Therapeutics Ltd. has announced positive topline data from its open-label Phase 2 clinical trial of ATH434 in individuals with multiple system atrophy $(MSA)$. The ATH434-202 trial assessed a patient population with more advanced MSA compared to the cohort in the earlier double-blind Phase 2 trial, ATH434-201. The results demonstrated clinical benefits on the Unified MSA Rating Scale and global measures of neurological symptoms, with neuroimaging biomarkers indicating target engagement and slowed brain atrophy. ATH434 was well-tolerated and exhibited a favorable safety profile. These findings align with previous data from the Phase 2 double-blind trial and support the further advancement of ATH434 in the treatment of MSA. As of now, there are no disease-modifying medications available for MSA, making the development of ATH434 significant. The results have been presented and are consistent with Alterity's ongoing efforts to address neurodegenerative diseases.
