Research Abstract |
Antibodies that promote FVIII activity do not appear to have been reported. In this study, anti-FVIII monoclonal antibody, mab216, that enhanced FVIII coagulation activity. The mab216 increased FVIII activity ~1.5-fold dose-dependently, FXa generation and thrombin generation were increased by ~1.4- and ~2.5-fold, respectively. An anti A2 epitope was identified and the antibody enhanced the cleavage at Arg372. The findings may cast new light on new principles for improving the treatment of haemophilia A patients.
