Agents, uses and methods for the treatment of synucleinopathy
The invention relates to novel monoclonal anti-alpha-synuclein antibodies. The antibodies can be used for treating a synucleinopathy such as Parkinson's disease (including idiopathic and inherited forms of Parkinson's disease), Diffuse Lewy Body Disease (DLBD), Lewy body variant of Alzheimer's disease (LBV), Combined Alzheimer's and Parkinson disease, pure autonomic failure and multiple system atrophy.
1. A method of treating Parkinson's disease or other synucleinopathy in a human subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of an antibody which specifically binds to human alpha-synuclein and comprises heavy chain CDR1, CDR2, and CDR3 comprising the amino acid sequences of SEQ ID NOs: 1, 34, and 3, respectively, and light chain CDR1, CDR2, and CDR3 comprising the amino acid sequences of SEQ ID NOs: 4, 5, and 6, respectively.
2. The method of claim 1 , wherein the Parkinson's disease is an idiopathic or inherited form of Parkinson's disease.
3. The method of claim 1 , wherein the synucleinopathy is selected from Gaucher's Disease, Diffuse Lew Body Disease, Lewy body variant of Alzheimer's disease, combined Alzheimer's and Parkinson's disease, pure autonomic failure, and multiple system atrophy.
4. The method of claim 1 , wherein the antibody is which is a single chain Fv, a disulphide-bonded Fv, an Fab fragment, a Fab′ fragment, or a F(ab) 2 fragment.
5. The method of claim 1 , wherein the antibody is a human antibody.
6. The method of claim 1 , wherein the antibody comprises a heavy chain variable domain comprising the amino acid sequence of SEQ ID NO:31 and a light chain variable domain comprising the amino acid sequence of SEQ ID NO:8.
7. The method of claim 1 , wherein the antibody binds an epitope within amino acid residues 112-117 (SEQ ID NO:9) of human alpha-synuclein (SEQ ID NO:10).
8. The method of claim 1 , wherein the antibody is formulated in a pharmaceutical composition.
9. A method of treating Parkinson's disease in a human subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of an antibody which specifically binds to human alpha-synuclein and comprises heavy chain CDR1, CDR2, and CDR3 comprising the amino acid sequences of SEQ ID NOs: 1, 34, and 3, respectively, and light chain CDR1, CDR2, and CDR3 comprising the amino acid sequences of SEQ ID NOs: 4, 5, and 6, respectively.
10. The method of claim 9 , wherein the antibody is which is a single chain Fv, a disulphide-bonded Fv, an Fab fragment, a Fab′ fragment, or a F(ab) 2 fragment.
11. The method of claim 9 , wherein the antibody is a human antibody.
12. The method of claim 9 , wherein the antibody comprises a heavy chain variable domain comprising the amino acid sequence of SEQ ID NO:31 and a light chain variable domain comprising the amino acid sequence of SEQ ID NO:8.
13. The method of claim 9 , wherein the antibody binds an epitope within amino acid residues 112-117 (SEQ ID NO:9) of human alpha-synuclein (SEQ ID NO:10).
14. The method of claim 9 , wherein the antibody is formulated in a pharmaceutical composition.
