Antibodies and their use in the treatment, prevention and diagnosis of a disease associated with SOD1 abnormalities
The present invention concerns an antibody which specifically binds to an abnormal superoxide dismutase 1 (SOD1), and which neutralizes its pathologic effect when administered to an animal such as a human. The antibody of the invention is a monoclonal antibody produced by hybridoma cell lines deposited with the International Depositary Authority of Canada on Aug. 29, 2006 under accession numbers ADI-290806-01, ADI-290806-02 and ADS-290806-03. The present invention also concerns the use of the antibody of the invention in the treatment, prevention and diagnosis of neurodegenerative diseases such as Amyotrophic lateral sclerosis, Parkinson and Alzheimer in an animal such as a human.
1. A hybridoma cell line deposited with the International Depositary Authority of Canada on Aug. 29, 2006 under accession number ADI-290806-03.
2. A monoclonal antibody produced by the hybridoma cell line according to claim 1 or an antigen-binding fragment thereof.
3. A method for treating amyotrophic lateral sclerosis associated with SOD1 abnormalities in an animal, said method comprising the step of administering an effective amount of at least an antibody as defined in claim 2 .
4. The method of claim 3 , wherein amyotrophic lateral sclerosis is familial amyotrophic lateral sclerosis.
5. The method of claim 3 , wherein amyotrophic lateral sclerosis is sporadic amyotrophic lateral sclerosis.
6. A composition comprising a pharmaceutically acceptable carrier and at least an antibody as defined in claim 2 .
7. A method for treating amyotrophic lateral sclerosis associated with SOD1 abnormalities in an animal, said method comprising the step of administering an effective amount of a composition as defined in claim 6 .
8. The method of claim 7 , wherein amyotrophic lateral sclerosis is familial amyotrophic lateral sclerosis.
9. The method of claim 7 , wherein amyotrophic lateral sclerosis is sporadic amyotrophic lateral sclerosis.
10. A method for the diagnosis of amyotrophic lateral sclerosis associated with SOD1 abnormalities in a biological sample of an animal, the method comprising steps of:
contacting at least an antibody as defined in claim 2 with the biological sample, and
detecting the presence of a specific binding of the antibody with an abnormal SOD1 protein, the presence of the specific binding indicating the presence of amyotrophic lateral sclerosis in the animal.
11. A kit for treatment or prevention of a disease amyotrophic lateral sclerosis associated with SOD 1 abnormalities in an animal, said kit comprising at least a container, said container containing at least an antibody as defined in claim 2 .
12. The kit of claim 11 , wherein amyotrophic lateral sclerosis is familial amyotrophic lateral sclerosis.
13. The kit of claim 12 , wherein amyotrophic lateral sclerosis is sporadic amyotrophic lateral sclerosis.
