Question · Q4 2025
Tom Bishop inquired about the CHMP's guidance on additional biomarker information for Blarcamesine, whether the ABCLEAR data could be included in the re-examination, the potential duration of a conditional trial if EMA approval is granted, Anavex's progress in exploring commercialization options with large pharma, and the mechanism of action for Collagen 24A1.
Answer
President and CEO Christopher Missling clarified that the CHMP seeks demonstration of Blarcamesine's benefit outweighing risks, suggesting objective biomarkers like brain atrophy could be helpful. He noted that Blarcamesine demonstrated less or halted brain shrinking, an objective marker of neurodegeneration, and that correlation between reduced atrophy and cognitive improvement would be presented. He emphasized the compelling clinical meaningful and significant improvements across various endpoints (CGI, quality of life, PIQ, MMSE, ADAS-Cog13, CDR-Sum of Boxes, ADCS-ADL) in ABCLEAR 2 and 3 populations, with 70% of patients showing a reversal of negative quality of life trajectory. He stated it's difficult to speculate on conditional trial duration but highlighted the significant unmet need. Anavex is expanding corporate development partnership activities, including presenting at a major conference in San Francisco. He explained that Collagen 24A1 is crucial for the extracellular matrix; its mutation impairs autophagy restoration, leading to a reduced response to Blarcamesine, while wild-type carriers (70% prevalence) show significant benefits, which will be published soon.
