Debiopharm and Salix pharmaceuticals sign license agreement for Sanvar®

Lausanne, Switzerland, and Raleigh, NC, US, September 5, 2006 – The Debiopharm Group (Debiopharm), a global independent biopharmaceutical development company specialising in oncology and serious medical conditions, and Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announce the signing of an exclusive license agreement granting Salix the right to sell, market and distribute, in the United States (US), SANVAR® IR (immediate release formulation) developed by Debiopharm for the treatment of acute esophageal variceal bleeding (EVB). The product is currently undergoing a confirmatory Phase III trial, in the US for the treatment of EVB secondary to portal hypertension. The US Food and Drug Administration (FDA) has reviewed the protocol under the Special Protocol Assessment (SPA) process. In addition to royalty payments on the sales of the product, under the terms of the agreement Salix will pay up to $14 million in up-front and regulatory and sales performance milestone payments to Debiopharm.

Commenting on the announcement, Bill Forbes, Pharm. D., Vice President, Research and Development, and Chief Development Officer, Salix, stated, “EVB is a life-threatening and frequent complication of late-stage liver cirrhosis. Survival is directly related to early control of bleeding and Sanvar works to reduce bleeding by reducing portal hypertension. There is no approved treatment for EVB in the US at this time. Currently a multicenter trial is being conducted in the US at several major gastro-enterology centers. It is anticipated that the study, will confirm the results of trials conducted earlier in Europe by Debiopharm, that demonstrated that the early use of SANVAR® with endoscopic treatment improves the control of bleeding and prevents re-bleeding episodes in patients with portal hypertension.”

Carolyn Logan, President and Chief Executive Officer, stated, “Salix’s licensing-in of SANVAR® is the latest demonstration of our commitment to providing gastroenterologists and their patients with innovative and effective products. Additionally, this acquisition demonstrates our continuing success in executing our strategy to identify emerging opportunities worldwide in order to expand our product portfolio. If SANVAR® is granted marketing approval by the FDA in the time frame we anticipate, we look forward to being able, by the end of 2007, to offer patients in the US the first product approved for this serious complication of late-stage liver cirrhosis.”

“We are thrilled to have a dedicated gastroenterology company like Salix as a partner for SANVAR® in the US. We are confident that their therapeutic focus along with their expertise in sales and marketing will help develop the full potential of SANVAR® in the important US market” said Loic Maurel, President and Chief Executive Officer of the Debiopharm Group Canadian subsidiary

SANVAR® (vapreotide acetate) is a synthetic octapeptide analogue of the naturally-occurring somatostatin hormone. It has similar pharmacological properties to native somatostatin but exhibits a longer duration of action. It is the only somatostatin analog to demonstrate statistically significant benefits in the early treatment of EVB in association with endoscopic therapy in a placebo-controlled clinical study (Cales et al. New England Journal of Medicine, 2001). Survival with hemostasis at 5 days was achieved significantly (p=0.021) more often with SANVAR® than with placebo. In patients with control of bleeding at day 5, SANVAR® (p=0.006) increased hemostasis and survival through day 42. Additional Phase III trials have been completed in Europe in this indication. SANVAR® can be stored at room temperature, an advantage over other products requiring refrigeration, allowing immediate administration, a key benefit in a life-threatening situation. It has been granted orphan drug status in the US, where EVB affects less than 200,000 patients per year and received an approvable letter from the FDA.
