Stroke, Volume 56, Issue Suppl_1, Page ATP214-ATP214, February 1, 2025. Background:Amyloid-related Imaging Abnormalities (ARIA) are adverse effects that occur during amyloid beta monoclonal antibody treatment for Alzheimer’s disease, including edema-type ARIA and hemorrhage-type ARIA. Few retrospective analysis have compared ARIA-H incidence among individual monoclonal antibodies, and a comprehensive comparison is currently lacking. After the approval of these antibodies, research has mainly focused on dosing frequency and drug dosage, leaving it unclear whether ARIA-H is associated with the specific characteristics of different monoclonal antibodies.Methods:1. For monoclonal antibodies targeting Aβ clearance, we selected seven: Aducanumab, Bapineuzumab, Crenezumab, Donanemab, Gantenerumab, Lecanemab, and Solanezumab. Our data is derived from systematic reviews and meta-analyses of Phase III clinical trials for these seven monoclonal antibodies. Data from Jeremic D et al. include six monoclonal antibodies (mAbs), while data from Qiao Y et al. include four mAbs. 2. For the evaluation variables, we selected the following factors: the form of monoclonal antibody binding to Aβ protein, binding affinity, binding epitope, Fc subtype of the monoclonal antibody, and the Aβ clearance rate. ARIA-H occurrence was used as a categorical variable for differential analysis. The odds ratio (OR) was utilized for data assessment, with an OR not equal to 1 and a 95% confidence interval excluding 1 used as the criterion for statistical significance. 3. We standardized the data for the seven monoclonal antibodies (mAbs). We compared the ARIA-H occurrence rates for the mAbs, taking into account other dimensional variables.Results:The risk of ARIA-H, from highest to lowest, is as follows: Donanemab, Aducanumab, Bapineuzumab, Lecanemab, Gantenerumab, Crenezumab, Solanezumab. Besides, ARIA-H is associated with the characteristics of mAb. (1)More mature Aβ clearance is associated with a higher risk of ARIA-H.(2)Lower clearance of Aβ oligomers is associated with a higher risk of ARIA-H.(3)Aβ clearance closer to the N-terminus is associated with a higher risk of ARIA-H.(4)mAb with an IgG4 structure are more likely to cause ARIA-H than those with an IgG1 structure.(5)Faster achievement of Aβ clearance thresholds is associated with a higher risk of ARIA-H.Conclusion:This research enhances our understanding of ARIA-H and may guide future monoclonal antibody drug development, which may improve the cognition and overall prognosis of Alzheimer’s disease patients.
