Rifaximin Demonstrates Statistically Significant Improvement in Co-Primary Endpoints in Treatment of Diarrhea-Associated Irritable Bowel Syndrome in Phase IIb StudyApproximately 20 Million Americans May Suffer From dIBS
RALEIGH, N.C.--(HSMN NewsFeed)--Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP ) today announced the successful completion and outcome of its Phase IIb trial to assess the efficacy and safety of rifaximin in the treatment of patients with diarrhea-associated irritable bowel syndrome (dIBS). Top-line results of this study demonstrate that the protocol-specified, intent-to-treat, co-primary endpoint comparison of a 14-day course of rifaximin at 550 mg twice-a-day, provides a statistically significant improvement in both adequate relief of dIBS symptoms and adequate relief of bloating, compared to placebo.
Salix acquired rights to market rifaximin in North America from Alfa Wassermann S.p.A. in Bologna, Italy. Alfa Wassermann markets rifaximin in Italy under the trade name Normix®.
