Methods for treatment of alport syndrome
Provided herein are methods for the treatment of Alport Syndrome, using modified oligonucleotides targeted to miR-21. In certain embodiments, a modified oligonucleotide targeted to miR-21 improves kidney function and/or reduces fibrosis in subjects having Alport Syndrome. In certain embodiments, administration of a modified oligonucleotide targeted to miR-21 delays the onset of end-stage renal disease in a subject having Alport Syndrome. In certain embodiments, a modified oligonucleotide targeted to miR-21 delays the need for dialysis or kidney transplant in a subject having Alport Syndrome.
1. A method of treating Alport Syndrome comprising administering to a subject having or suspected of having Alport Syndrome a pharmaceutical composition comprising a therapeutically effective amount of a modified oligonucleotide consisting of 19 linked nucleosides and having the structure 5′-A E C S ATC S AGTC S TGAU S AAGC S TA E -3′ (SEQ ID NO: 3), where nucleosides not followed by a subscript are β-D-deoxyribonucleosides; nucleosides followed by a subscript “E” are 2′-MOE nucleosides; nucleosides followed by a subscript “S” are S-cEt nucleosides, and each internucleoside linkage is a phosphorothioate internucleoside linkage.
2. The method of claim 1 wherein the subject has been diagnosed as having Alport Syndrome prior to administering the pharmaceutical composition.
3. The method of claim 1 , wherein the subject is male.
4. The method of claim 1 , wherein the subject is female.
5. The method of claim 1 , wherein the Alport Syndrome is the X-linked form of Alport Syndrome.
6. The method of claim 1 , wherein the Alport Syndrome is the autosomal form of Alport Syndrome.
7. The method of claim 5 , wherein the subject is female.
8. The method of claim 5 , wherein the subject is male.
9. The method of claim 6 , wherein the subject is female.
10. The method of claim 6 , wherein the subject is male.
11. The method of claim 1 , wherein the subject has a mutation in the gene encoding the alpha 3 chain of type IV collagen.
12. The method of claim 11 , wherein the subject is female.
13. The method of claim 11 , wherein the subject is male.
14. The method of claim 1 , wherein the subject has a mutation in the gene encoding the alpha 4 chain of type IV collagen.
15. The method of claim 14 , wherein the subject is female.
16. The method of claim 14 , wherein the subject is male.
17. The method of claim 1 , wherein the subject has a mutation in the gene encoding the alpha 5 chain of type IV collagen.
18. The method of claim 17 , wherein the subject is female.
19. The method of claim 17 , wherein the subject is male.
20. The method of claim 1 , wherein the pharmaceutical composition is a sterile aqueous solution.
