AMH-COMPETITIVE ANTAGONIST ANTIBODY

The present invention relates to a competitive antagonist antibody that specifically binds to AMHR-II, said antibody comprising (a) a heavy chain wherein the variable domain comprises a H-CDR1 having a sequence set forth as SEQ ID NO: 3; a H-CDR2 having a sequence set forth as SEQ ID NO: 4; and a H-CDR3 having a sequence set forth as SEQ ID NO: 5; and (b) a light chain wherein the variable domain comprises at least a CDR selected from the group consisting of a L-CDR1 having a sequence set forth as SEQ ID NO: 8, a L-CDR2 having a sequence set forth as SEQ ID NO: 9; and a L-CDR3 having a sequence set forth as SEQ ID NO: 10.A nucleic acid sequence encoding said antibody, a vector comprising the nucleic acid sequence, a host cell comprising said nucleic acid sequence or vector, an immunoconjugate comprising the said antibody, a pharmaceutical composition comprising the said antibody or immunoconjugate, and the use as a drug of the said antibody, cell or composition is also considered in the present invention.
