Abstract

The invention provides compositions and methods for treatment of amyloidogenic diseases. Such methods entail administering an agent that induces a beneficial immune response against an amyloid deposit in the patient. The methods are particularly useful for prophylactic and therapeutic treatment of Alzheimer'"'"'s disease. In such methods, a suitable agent is Aβ peptide or an antibody thereto.

Claims

1. A method of preventing or treating a disease characterized by an amyloid deposit of Aβ

in a patient, comprising;

administering an Aβ

peptide and an adjuvant in a regime effective to induce an immune response comprising antibodies to the Aβ

peptide, the adjuvant enhancing the immune response to the Aβ

peptide, and thereby prevent or treat the disease in the patient.

2. The method of claim 1, wherein the patient is a human.

3. The method of claim 1, wherein the disease is Alzheimer'"'"'s disease.

4. The method of anyone of claims 1 or 2-3, wherein the patient is asymptomatic.

5. The method of any one of claims 1 or 2-3, wherein the patient is under 50.

6. The method of any one of claims 1 or 2-3, wherein the patient has inherited risk factors indicating susceptibility to Alzheimer'"'"'s disease.

7. The method of any one of claims 1 or 2-3, wherein the patient has no known risk factors for Aliheimer'"'"'s disease.

10. The method of claim 1, wherein the Aβ

peptide is administered in aggregated form.

11. The method of any one of claims 1 or 2-3, wherein the Aβ

peptide is administered orally, subcutaneously, intramuscularly, topically or intravenously.

12. The method of any of any one of claims 1 or 2-3, wherein the Aβ

peptide is administered intramuscularly or subcutaneously.

13. The method of any one of claims 1 or 2-3, further comprising monitoring the patient for the immune response.

14. The method of claim 1, wherein the adjuvant and the Aβ

peptide are administered together as a composition.

15. The method of claim 1, wherein the adjuvant is administered before the Aβ

peptide.

16. The method of claim 1, wherein the adjuvant is administered after the Aβ

peptide.

17. The method of claim 1, wherein the adjuvant is alum.

18. The method of claim 1, wherein the adjuvant is MPL.

19. The method claim 1, wherein the adjuvant is QS21.

20. The method of claim 1, wherein the dose of the Aβ

peptide is greater than 10 μ

g.

21. The method of claim 1, wherein the Aβ

peptide is administered with GM-CSF in the regime.

23. The method of claim 1, wherein the adjuvant is M-CSF.

24. The method of claim 1, wherein the dosage is greater than 20 μ

g.

8. A method of preventing or treating a disease characterized by an amyloid deposit of Aβ

in a patient, comprising;

administering an Aβ

peptide in a regime effective to induce an immune response comprising antibodies to the Aβ

peptide and thereby prevent or treat the disease in the patient, wherein the dose of Aβ

peptide administered to the patient at least 50 μ

g.

9. The method of claim 8, wherein the dose of Aβ

peptide administered to the patient is at least 100 μ

g.

22. A method of preventing or treating a disease characterized by an amyloid deposit of Aβ

in a patient, comprising;

administering an Aβ

peptide in a regime effective to induce an immune response comprising antibodies to the Aβ

peptide and thereby prevent or treat the disease in the patient; and

monitoring the patient for the immune response, wherein the monitoring comprises detecting antibodies having Aβ

peptide binding specificity.
