An antibody which binds to Lysophosphatidic Acid Receptor 1 (“LPAR1”), wherein the antibody is an inhibitor of LPAR1, wherein the antibody comprises three heavy chain CDRs (HCDR1-3) and three light chain CDRs (LCDR1-3), wherein the antibody comprises a HCDR1 comprising the amino acid sequence set forth in SEQ ID NO:
- 1, a HCDR2 comprising the amino acid sequence set forth in SEQ ID NO:
- 100, a HCDR3 comprising the amino acid sequence set forth in SEQ ID NO:
- 101, a LCDR1 comprising the amino acid sequence set forth in SEQ ID NO:
- 4, a LCDR2 comprising the amino acid sequence set forth in SEQ ID NO:
- 98 and a LCDR3 comprising the amino acid sequence set forth in SEQ ID NO:
- 6.
An antibody which binds to LPAR1, wherein the antibody comprises:
- a. two heavy chain polypeptides, wherein each of the heavy chain polypeptides comprises a heavy chain variable region comprising three heavy chain CDRs (HCDR1-3) wherein HCDR1 comprises the amino acid sequence set forth in SEQ ID NO:
- 1, HCDR2 comprises the amino acid sequence set forth in SEQ ID NO:
- 100, and HCDR3 comprises the amino acid sequence set forth in SEQ ID NO:
- 101;
- and
- b. two light chain polypeptides, wherein each of the light chain polypeptides comprises a light chain variable region comprising three light chain CDRs (LCDR1-3) wherein LCDR1 comprises the amino acid sequence set forth in SEQ ID NO:
- 4, LCDR2 comprises the amino acid sequence set forth in SEQ ID NO:
- 98, and LCDR3 comprises the amino acid sequence set forth in SEQ ID NO:
- 6;
- and
- wherein the antibody is an IgG1 antibody.
An antibody which binds to LPAR1, wherein the antibody comprises
- a. two heavy chain polypeptides, each of the heavy chain polypeptides comprising a heavy chain variable region comprising the amino acid sequence set forth in SEQ ID NO:
- 102;
- and
- b. two light chain polypeptides, each of the light chain polypeptides comprising a light chain variable domain comprising the amino acid sequence set forth in SEQ ID NO:
- 99;
- and
- wherein the antibody is an IgG1 antibody.
An antibody which binds to LPAR1, wherein the antibody comprises two heavy chain polypeptides and two light chain polypeptides, wherein each of the heavy chain polypeptides comprises the amino acid sequence set forth in SEQ ID NO:
- 1220 and each of the light chain polypeptides comprises the amino acid sequence set forth in SEQ ID NO:
- 1219, provided that the residue corresponding to position 255 of SEQ ID NO:
- 1220 is “Y”, the residue corresponding to position 257 of SEQ ID NO:
- 1220 is “T” and the residue corresponding to position 259 of SEQ ID NO:
- 1220 is “E”.
