Antibodies to receptor of advanced glycation end products (RAGE) and uses thereof
View Patent ↗The present application relates to isolated proteins, particularly monoclonal antibodies, in particular CDR-grafted, humanized antibodies which bind to RAGE protein. Specifically, these antibodies have the ability to inhibit the binding of RAGE to its various ligands. The antibodies or portions thereof of described in the present application are useful for treating a disease or disorder characterized by or induced by pathophysiological ligands of RAGE, for example missfolded proteins like amyloid β and advanced glycation-end-products.
1. An isolated monoclonal antibody or antigen-binding fragment thereof comprising an antigen binding domain, said antibody or antigen-binding fragment capable of binding an epitope of a human RAGE molecule, said antigen binding domain comprising:
three heavy chain variable region CDRs having the sequences SEQ ID NO: 2, SEQ ID NO: 3, and SEQ ID NO: 4, and three light chain variable region CDRs having the sequences SEQ ID NO: 6, SEQ ID NO: 7, and SEQ ID NO: 8.
2. The antibody according to claim 1 , further comprising a human acceptor framework.
3. The antibody of claim 1 comprising a heavy chain variable domain of SEQ ID NO: 1; and/or a light chain variable domain of SEQ ID NO: 5.
4. An isolated nucleic acid molecule, which encodes the amino acid sequence of the antibody or antigen-binding fragment of claim 1 .
5. A vector comprising an isolated nucleic acid molecule according to claim 4 .
6. A host cell comprising the vector according to claim 5 .
7. A method of producing an antibody capable of binding RAGE or an antigen-binding fragment thereof, comprising culturing the host cell according to claim 6 in culture medium under conditions sufficient to produce a binding protein capable of binding RAGE the antibody or antigen-binding fragment thereof.
8. An antibody or antigen-binding fragment thereof produced according to the method of claim 7 .
9. A composition for the release of an antibody, said composition comprising:
(a) a formulation, wherein said formulation comprises the antibody of claim 1 in crystallized form as an ingredient; and
(b) at least one polymeric carrier.
10. A pharmaceutical composition comprising the antibody of claim 1 , and a pharmaceutically acceptable carrier.
