Clinical trials showed that previously untreated patients with severe HA present higher rates of inhibitor development if treated with rec-FVIII products and that differences do exist as to inhibitor's formation among different rec-FVIII products. This finding could arise from several causes, such as absence of von Willebrand factor, different glycosylation profiles, or processes of molecular aggregation of the recombinant FVIII molecules %K recombinant FVIII %K molecular aggregation %K Hemophilia A %K dynamic light scattering %K FVIII inhibitors %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6524925/
