Antisense oligonucleotides (ODN) against SMAD7 and uses thereof in medical field
View Patent ↗The invention relates to antisense oligonucleotidic sequences (ODN) against Smad7 suitably modified, and their uses in medical field as therapeutic biological agents, in particular in the treatment of chronic inflammatory bowel disease, such as Crohn's disease and ulcerative colitis.
1. An antisense oligonucleotide phosphorothioate against SMAD7 consisting of the following sequence: 5′-GTXGCCCCTTCTCCCXGCAGC-3′ (SEQ ID NO:17), wherein X is 5-methyl-2′-deoxycytidine and all internucleoside linkages are phosphorothioate linkages.
2. A pharmaceutical composition comprising the antisense oligonucleotide phosphorothioate of claim 1 and a pharmaceutically acceptable adjuvant and/or excipient.
3. The pharmaceutical composition of claim 2 , wherein the pharmaceutical composition is an oral pharmaceutical composition.
4. A method of treating inflammatory bowel disease, comprising administering to a patient in need thereof an effective amount of the antisense oligonucleotide phosphorothioate of claim 1 , wherein the antisense oligonucleotide phosphorothioate is effective to treat inflammatory bowel disease.
5. The method of claim 4 , wherein the inflammatory bowel disease is Crohn's disease.
6. The method of claim 4 , wherein the inflammatory bowel disease is ulcerative colitis.
