Abstract
Disclosed herein are antibodies capable of binding to plasma kallikrein and inhibit its activity. Such antibodies interact with one or more critical residues in the catalytic domain of the plasma kallikrein. The antibodies may also contain specific heavy chain complementarity determining region 3 (CDRs) motifs and optionally specific residues at certain positions within both the heavy chain variable region and the light chain variable region.
Claims16
An isolated antibody that binds human plasma kallikrein (PKal), wherein the antibody comprises a heavy chain variable region that comprises complementarity determining region 1 (HC CDR1) having the sequence HYIMM (SEQ ID NO:
- 62), a complementarity determining region 2 (HC CDR2) having the sequence GIYSSGGITVYADSVKG (SEQ ID NO:
- 63), and complementarity determining region 3 (HC CDR3), and wherein the HC CDR3 comprises the sequence:
- (i) RRIGIPRRDAFDI (SEQ ID NO:
- 28),
- (ii) RRIGIPRRDEFDI (SEQ ID NO:
- 29),
- (iii) RRTGAPRRDAFDI (SEQ ID NO:
- 30),
- (iv) RRTGSPRRDAFDI (SEQ ID NO:
- 31),
- (v) RRTGLPRRDAFDI (SEQ ID NO:
- 32), or
- (vi) RRTIGPRRDEFDI (SEQ ID NO:
- 33);
- and
- a light chain (LC) variable region that comprises a complementarity determining region 1 (LC CDR1) having the sequence RASQSISSWLA (SEQ ID NO:
- 59), a complementarity determining region 2 (LC CDR2) having the sequence KASTLES (SEQ ID NO:
- 60), and a complementarity determining region 3 (LC CDR3) having the sequence QQYNTYWT (SEQ ID NO:
- 61).
