Oligonucleotide-containing pharmacological compositions and their use
The present invention relates to methods and compositions containing oligonucleotides suitable for administration to humans and other mammals.
1. A composition suitable for administration in a mammal suffering from a pathological disorder or disease comprising at least three modified oligonucleotides, wherein a first, a second, and a third modified oligonucleotide each comprises about seven to seventy-five nucleotides containing seven or more contiguous ribose groups linked by achiral 5′ to 3′ internucleotide phosphate linkages, wherein at least one ribose group of at least one of said modified oligonucleotides has a modified 2′ substituent, wherein the 5′ and 3′ ends of at least one of said modified oligonucleotides are blocked, and wherein said first modified oligonucleotide is complementary to a region of phosphodiesterase 4 (SEQ ID NO: 82); and said second modified oligonucleotide is complementary to a region of phosphodiesterase 5 (SEQ ID NO: 95), and said third modified oligonucleotide is complementary to a region of cyclo-oxygenase 2 (SEQ ID NO: 87).
2. The composition of claim 1 , further comprising a fourth modified oligonucleotide, wherein said fourth modified oligonucleotide comprises about seven to seventy-five nucleotides containing seven or more contiguous ribose groups linked by achiral 5′ to 3′ internucleotide phosphate linkages, and wherein said fourth modified oligonucleotide is complementary to a region of Cd-18 (SEQ ID NO: 86).
3. The composition of claim 2 , further comprising a fifth modified oligonucleotide, wherein said fifth modified oligonucleotide comprises about seven to seventy-five nucleotides containing seven or more contiguous ribose groups linked by achiral 5′ to 3′ internucleotide phosphate linkages, and wherein said fifth modified oligonucleotide is complementary to a region of HMGCoA reductase (SEQ ID NO: 88).
4. The composition of claim 2 , wherein said fourth modified oligonucleotide comprises SEQ ID NO: 5.
5. The composition of claim 3 , further comprising a sixth modified oligonucleotide, wherein said sixth modified oligonucleotide comprises about seven to seventy-five nucleotides containing seven or more contiguous ribose groups linked by achiral 5′ to 3′ internucleotide phosphate linkages, and wherein said sixth modified oligonucleotide is complementary to a region of IL-5 (SEQ ID NO: 89).
6. The composition of claim 3 , wherein said fifth modified oligonucleotide comprises SEQ ID NO: 7, SEQ ID NO: 8, or SEQ ID NO: 9.
7. The composition of claim 5 , wherein said sixth modified oligonucleotide comprises SEQ ID NO: 10.
8. The composition of claim 1 , 2 , 3 , or 5 , wherein said at least three modified oligonucleotides are each complementary to a region of said gene selected from the group consisting of the 5′ UTR region, translational start site, and transitional termination site.
9. The composition of claim 1 , wherein one or more of said at least three modified oligonucleotides is present at a concentration effective to reduce the expression of said gene to which it is complementary.
10. The composition of claim 1 , wherein said at least three modified oligonucleotides are suitable for oral administration.
11. The composition of claim 1 , wherein said 2′ substituent is selected from the group consisting of methoxy, propoxy, methoxy-ethoxy, fluorine, chlorine, bromine and iodine.
12. The composition of claim 1 , further comprising a pharmaceutically acceptable excipient.
13. The composition of claim 1 , wherein said mammal is a human.
14. The composition of claim 1 , wherein said 5′ and 3′ ends comprise a butanol.
15. The composition of claim 1 , wherein said first modified oligonucleotide comprises SEQ ID NO: 1 and said second modified oligonucleotide comprises SEQ ID NO: 16.
16. The composition of claim 1 , wherein said third modified oligonucleotide comprises SEQ ID NO: 6.
