Human antibodies against eotaxin and their use
Specific binding members directed to eotaxin-1, in particular human antibodies and antibody fragments against human eotaxin-1 and especially those which neutralise eotaxin-1 activity. The antibodies VH and/or VL domain of the scFv fragment herein termed CAT-212 and of the IgG4 antibody herein termed CAT 213. One or more complementary determining regions (CDRs) of the CAT-213/-213 VH and/or VL domains especially VH CRD3 in other antibody framework regions. Compositions containing specific binding members and their use in methods of inhibiting or neutralising eotaxin, including methods of treatment or the human or animal body by therapy.
1. A pharmaceutical composition comprising a specific binding member that binds human eotaxin and a pharmaceutically acceptable excipient, carrier, buffer or stabilizer, wherein the specific binding member comprises:
(i) an antibody VH domain comprising a VH CDR1, a VH CDR2 and a VH CDR3, wherein said VH CDR1, VH CDR2 and VH CDR3 comprise the amino acid sequences of SEQ ID NO:5, SEQ ID NO:6 and SEQ ID NO:7, respectively; and
(ii) an antibody VL domain comprising a VL CDR1, a VL CDR2 and a VL CDR3, wherein said VL CDR1, VL CDR2 and VL CDR3 comprise the amino acid sequences of SEQ ID NO:8, SEQ ID NO:9 and SEQ ID NO:10, respectively.
