Sucampo Pharmaceuticals Presents Data on Cobiprostone at American College of Gastroenterology Annual Scientific Meeting

BETHESDA, Md.--(BUSINESS WIRE)--Oct 15, 2007 - Sucampo Pharmaceuticals, Inc., (Nasdaq: SCMP) today announced the presentation of a scientific poster addressing the potential ability of its clinical compound, cobiprostone, to reduce cellular death and promote the regrowth of cells damaged by indomethacin, a commonly prescribed non-steroidal anti-inflammatory drug, or NSAID. The poster was presented yesterday at the American College of Gastroenterology (ACG) Annual Scientific Meeting in Philadelphia.

The poster summarized results of an in vitro study conducted by the University of Cincinnati, which examined the effects of cobiprostone on indomethacin-induced damage of human intestinal T84 cells. This examination included studying the effects of the compound on specific mitochondrial dysfunctions believed to be involved in NSAID-induced cell death, as well as on recovery of the cells after treatment with indomethacin.

Investigators also found that cobiprostone prevented indomethacin-induced increases in both calcium ions and mitochondrial dysfunction, and concluded that cobiprostone reduced indomethacin-induced cell death and promoted cell regrowth.

"These data strongly suggest that activation of chloride channels underlie the protective effects of cobiprostone against NSAID-induced cellular damage," said the study's investigator, Professor John Cuppoletti, Ph.D., of the Department of Molecular and Cellular Physiology at the University of Cincinnati.

The study abstract has been published in the September 2007 issue of The American Journal of Gastroenterology 102 (s2), S156-S174.

According to the ACG, an estimated 13 million people in the United States use NSAIDs on a regular basis. Approximately 15-30 percent of chronic NSAID users experience gastrointestinal ulcers and bleeding. These side effects have been associated with the inhibition of the enzyme known as cyclooxygenase as well as other NSAID mechanisms that have a direct cytotoxic effect on gastric mucosal cells.

Cobiprostone is a functional fatty acid and a member of a class of compounds called prostones. It is a locally acting chloride-channel activator that targets ion channels located in the liver and the gastrointestinal tract.

Cobiprostone, which has been developed for oral administration, has been evaluated in two Phase 1 trials in healthy volunteers, and in three Phase 2 proof-of-concept trials for other indications. In September 2007, patient enrollment began in a multi-center Phase 2, dose-finding trial evaluating cobiprostone for the prevention of ulcers and other gastrointestinal injuries in arthritis patients treated with NSAIDs.
