Methods and drug products for treating Alzheimer's disease
View Patent ↗Provided herein are drug products with low dose pioglitazone for use in the treatment (e.g., delay of onset) of cognitive impairment of the Alzheimer's type. Methods of manufacture thereof are also provided. Further provided are methods of treatment for Alzheimer's disease including administering a drug product with low dose pioglitazone. The methods may include determining whether the subject is at risk of developing Alzheimer's disease based upon the subject's age and TOMM40 523 genotype.
1. A method of treating cognitive impairment of the Alzheimer's type in a human subject in need thereof, comprising administering to said subject about 0.5 milligrams to about 9 milligrams of pioglitazone.
2. The method of claim 1 , wherein said treating comprises delaying the onset of cognitive impairment of the Alzheimer's type.
3. The method of claim 1 , wherein said treating comprises delaying the onset of cognitive impairment of the Alzheimer's type in a human subject at increased risk of developing cognitive impairment of the Alzheimer's type within the next 5-7 years, said risk based upon the subject's age and rs10524523 genotype.
4. The method of claim 1 , wherein the low dose pioglitazone is administered in unit dosage form.
5. The method of claim 4 , wherein the unit dosage form comprises from 0.5 to 9 milligrams of pioglitazone.
6. The method of claim 4 , wherein the unit dosage form comprises from 0.5 to 6 milligrams of pioglitazone.
7. The method of claim 4 , wherein said unit dosage form comprises from 0.5 to 1.5 milligrams of pioglitazone.
8. The method of claim 1 , wherein said administering is once daily.
9. The method of claim 1 , wherein
(i) the subject is about age 62 or more and has an L,L or L,VL genotype;
(ii) the subject is about age 74 or more and has an S,L genotype;
(iii) the subject is about age 76 or more and has an S,VL genotype; or
(iv) the subject is about age 77 or more and has an S,S genotype; and
wherein the genotype is based on a length of poly-T residues at each allele at rs10524523 in the TOMM40 gene, and wherein
(a) S is the short poly-T length having less than 19 T residues;
(b) L is the long poly-T length having 19-29 T residues; and
(c) VL is the very long poly-T length having 30 or more T residues.
10. The method of claim 9 , wherein the subject is age 62 or more and has the L,L or L,VL genotype.
11. The method of claim 9 , wherein the subject is age 74 or more and has the S,L genotype.
12. The method of claim 9 , wherein the subject is age 76 or more and has the S,VL genotype.
13. The method of claim 9 , wherein the subject is age 77 or more and has the S,S genotype.
14. The method of 9 , wherein said subject further does not have an ApoE genotype of ε2/ε2 or ε2/ε3.
15. The method of claim 9 , wherein 0.5 to 9 milligrams of pioglitazone is administered to said subject.
16. The method of claim 9 , wherein 0.5 to 6 milligrams of pioglitazone is administered to said subject.
17. The method of claim 9 , wherein 0.5 to 1.5 milligrams of pioglitazone is administered to said subject.
18. The method of claim 9 , wherein said treating comprises delaying the onset of cognitive impairment of the Alzheimer's type.
19. The method of claim 18 , wherein said subject has normal cognition.
20. The method of claim 19 , wherein 0.5 to 9 milligrams of pioglitazone is administered to said subject.
21. The method of claim 19 , wherein 0.5 to 6 milligrams of pioglitazone is administered to said subject.
22. The method of claim 19 , wherein 0.5 to 1.5 milligrams of pioglitazone is administered to said subject.
23. The method of claim 1 , wherein the pioglitazone is in an oral modified release formulation, controlled release formulation, or extended release formulation.
24. The method of claim 1 , wherein the subject has one or more symptoms of cognitive impairment of the Alzheimer's type.
