Antibodies binding AXL
The present disclosure relates to anti-AXL antibodies, immunoconjugates, compositions and method of treatment of cancer with such anti-AXL antibodies, immunoconjugates, or compositions.
1. A method of diagnosing a cancer characterized by AXL expression, comprising administering to a subject at risk of developing said cancer
an antibody which binds to AXL and detecting the amount of bound antibody,
wherein the antibody comprises a VH region comprising the CDR1, CDR2, and CDR3 sequences of SEQ ID NOs: 36, 37, and 38, respectively, and a VL region comprising the CDR1, CDR2, and CDR3 sequences of SEQ ID NO: 39, GAS, and SEQ ID NO: 40, respectively,
wherein accumulation of AXL-expressing cells is indicative of the presence of the cancer.
2. The method of claim 1 , wherein said antibody comprises a VH region comprising SEQ ID NO: 1 and a VL region comprising SEQ ID NO: 2.
3. The method of claim 1 , wherein said antibody binds to an epitope within positions L121 to Q129 of human AXL (SEQ ID NO: 130).
4. The method of claim 1 , wherein said antibody comprises a heavy chain of an isotype selected from the group consisting of IgG1, IgG2, IgG3, and IgG4.
5. The method of claim 1 , wherein the antibody is a full-length monoclonal antibody.
6. The method of claim 1 , wherein the antibody is an effector-function-deficient antibody, a stabilized IgG4 antibody, or a monovalent antibody.
7. The method of claim 1 , wherein the antibody is a single-chain antibody.
8. A method of diagnosing a cancer characterized by AXL expression, comprising administering a pharmaceutical composition to a subject at risk of developing said cancer comprising
an antibody which binds to AXL, and detecting the amount of bound antibody,
wherein the antibody comprises a VH region comprising the CDR1, CDR2, and CDR3 sequences of SEQ ID NOs: 36, 37, and 38, respectively, and a VL region comprising the CDR1, CDR2, and CDR3 sequences of SEQ ID NO: 39, GAS, and SEQ ID NO: 40, respectively,
wherein accumulation of AXL-expressing cells, is indicative of the presence of the cancer.
