ABSTRACT:
The invention relates to an anti-idiotypical antibody targeting an antibody inhibiting the human factor VIII, said inhibiting antibody targeting the C2 region of the human factor VIII, the variable region of each of the light chains thereof being encoded by a sequence of nucleic acids of which at least 70% is identical to the murine sequence of nucleic acids SEQ ID NO: 1, and the variable region of each of the heavy chains thereof being encoded by a sequence of nucleic acids of which at least 70% is identical to the murine sequence of nucleic acids SEQ ID NO: 2, the constant regions of the light chains and the heavy chains being constant regions from a non-murine species. The invention also relates to the use of said antibody for activating the FcγRIII receptors of cytotoxic immune cells, and to the production of a medicament especially for the treatment of haemophilia A.
