Treatment method for inflammatory chronic disease using sirna
A recently granted patent (Publication Number: US11911409B2) discloses a method for treating chronic diseases, specifically inflammatory bowel disease, in patients in need. The method involves administering a pharmaceutical composition along with a biological preparation that inhibits leukocyte tissue invasion, inflammatory cytokines, or a combination of both. The pharmaceutical composition includes an active ingredient such as a siRNA that suppresses the expression of the CHST15 gene or a DNA vector expressing the siRNA. The biological preparations mentioned in the claims include Etrolizumab, Vedolizumab, Natalizumab, PF-00547659, and Vercirnon for inhibiting leukocyte tissue invasion, and antibodies targeting inflammatory cytokines like TNF-a, IL-17, IL-18, IL-23, IL-1p, and GM-CSF.
Furthermore, the method also involves administering additional treatments such as 5-aminosalicyclic acid preparations, steroid preparations, thiopurine preparations, and immunosuppressants like tacrolimus or cyclosporine in combination with the pharmaceutical composition and biological preparations. The administration can be done systemically or locally, with options for oral administration, intravenous injection, or submucosal administration into the intestine of the patient. The patent also covers the use of complexes for oral administration, including an active ingredient and N-acetylated chitosan, specifically targeting the suppression of the CHST15 gene for treating inflammatory bowel diseases like Crohn's disease or ulcerative colitis.
