Abstract

The present invention provides pharmaceutical formulations for oral administration of antisense oligonucleotides, such as antisense oligonucleotides against SMAD7. The pharmaceutical formulations can be used to treat Crohn's disease, ulcerative colitis and chronic inflammatory bowel disease.

First claim

What is claimed is:

1. An oral dosage form comprising:
An intra-granular phase comprising an oligonucleotide comprising the nucleotide sequence of SEQ ID NO: 1 or a pharmaceutically acceptable salt thereof; an extra-granular phase comprising a disintegrant; and an enteric coating comprising an ethylacrylate-methacrylic acid copolymer, wherein the oligonucleotide is released from the oral dosage form in an environment of pH 6.6 over a period of 30 minutes in an HPLC dissolution method.

2. The oral dosage form of claim 1 , wherein at least one of the internucleoside linkages of SEQ ID NO: 1 is an O,O-linked phosphorothioate.

3. The oral dosage form of claim 1 , wherein all of the internucleoside linkages of SEQ ID NO: 1 are O,O-linked phosphorothioates.

4. The oral dosage form of claim 1 , wherein the oligonucleotide is the sodium salt of SEQ ID NO: 1.

5. The oral dosage form of claim 1 , wherein the oral dosage form is a tablet.

6. The oral dosage form of claim 5 , wherein said enteric coating is about 8% to about 18% by weight of the tablet.

7. The oral dosage form of claim 5 , wherein said enteric coating is about 8% to about 15% by weight of the tablet.

8. The oral dosage form of claim 5 , wherein said enteric coating is about 12% to about 16% by weight of the tablet.

9. The oral dosage form of claim 5 , wherein said enteric coating is about 10% to about 12% by weight of the tablet.

10. The oral dosage form of claim 1 , wherein the oral dosage form further comprises a pharmaceutically acceptable filler.

11. The oral dosage form of claim 10 , wherein the pharmaceutically acceptable filler is mannitol.

12. The oral dosage form of claim 1 , having about 35 mg of the oligonucleotide.

13. The oral dosage form of claim 1 , having about 40 mg of the oligonucleotide.

14. The oral dosage form of claim 1 , having about 50 mg of the oligonucleotide.

15. The oral dosage form of claim 1 , having about 70 mg of the oligonucleotide.

16. The oral dosage form of claim 1 , having about 100 mg of the oligonucleotide.

17. The oral dosage form of claim 1 , having about 150 mg of the oligonucleotide.

18. The oral dosage form of claim 1 , wherein when orally administered to a patient, results in substantially minimal plasma concentration of the oligonucleotide or a pharmaceutically acceptable salt thereof in the patient.

19. The oral dosage form of claim 1 , wherein the oral dosage form is suitable for delivering the oligonucleotide or a pharmaceutically acceptable salt thereof substantially to the terminal ileum and/or right colon of a patient.

20. A method of treating Crohn's disease comprising orally administering to a patient in need thereof an oral dosage form of claim 1 .

21. A method of treating ulcerative colitis comprising orally administering to a patient in need thereof an oral dosage form of claim 1 .

22. A method of treating chronic inflammatory bowel disease comprising orally administering to a patient in need thereof an oral dosage form of claim 1 .

23. The method of any one of claims 20 - 22 , wherein upon orally administering the oral dosage form, said oral dosage form is substantially delivered to the terminal ileum and/or right colon of the patient.
