Anti-Idiotypic Antibodies Neutralizing the Inhibitory Activity of an Inhibitory Antibody Directed Against the C1 Domain of Factor VIII
First Claim
1. A monoclonal anti-idiotypic antibody directed against a Factor VIII human inhibitory antibody, said inhibitory antibody being directed against the C1 domain of Factor VIII, wherein at least one CDR region (Complementarity Determining Region) of each of the light chains of said antibody contains a peptide sequence having at least 70% identity to a sequence selected from the sequences SEQ ID NO:
- 12, SEQ ID NO;
13, SEQ ID NO;
14 and in that at least one CDR region of each of the heavy chains of said antibody contains a peptide sequence having at least 70% identity to a sequence selected from the sequences SEQ ID NO;
9, SEQ ID NO;
10, SEQ ID NO;
11.
