Alicaforsen selectively inhibits ICAM‑1 gene expression. Over-expression of ICAM‑1 occurs in a wide variety of inflammatory disorders, including ulcerative colitis (UC), pouchitis and tissues in the eye, gastrointestinal teact, lungs and skin. UC is an inflammatory bowel disease of the colon, a part of the large intestine, and pouchitis is an inflammation of the surgically constructed internal pouch created in UC patients when their diseased colons are removed. [ISIS Pharmaceutical Website] Alicaforsen is a RNase H dependent phosphorothioate-modified antisense oligodeoxynucleotide inhibitor which shuts down specific sequences of intracellular adhesion molecule 1 (ICAM1) mRNA and thus production of ICAM1, which prevents the inflammatory response. ICAM is a cell surface glycoprotein (immunoglobulin superfamily) which facilitates leukocyte adhesion and antigen presentation in the intestinal mucosa. Alicaforsen hybridizes the oligonucleotide strand with the target mRNA to suppress expression of ICAM1.
Investigated for use/treatment in crohn's disease and ulcerative colitis.
