Alfasigma USA Announces ZELNORM™ (tegaserod) Now Available for Treatment of Irritable Bowel Syndrome with Constipation

BEDMINSTER, N.J.--(BUSINESS WIRE)-- Alfasigma USA, Inc. today announced that ZELNORM™ (tegaserod) is now available in the United States as a prescription pharmaceutical treatment for irritable bowel syndrome with constipation (IBS-C) in adult women less than 65 years of age. Alfasigma USA acquired ZELNORM from Sloan Pharma S.à r.l., a subsidiary of US WorldMeds Holdings, LLC, in July 2019.

“We are pleased to inform U.S. physicians and pharmacists about the reintroduction of ZELNORM and how Alfasigma USA is supporting the availability, access to, and appropriate use of this important medicine for the many patients who cope daily with an urgent need for new treatment options,” said Bryan Downey, president and chief executive officer at Alfasigma USA. “Our growing U.S. organization and national sales force is excited to lead the return of ZELNORM and committed to making a positive difference in the lives of patients.”

Originally approved in 2002 as the first prescription medication for IBS-C, ZELNORM was voluntarily withdrawn from the market in 2007 due to concerns regarding possible cardiovascular risk. In March 2019, ZELNORM was approved for reintroduction in the U.S. for use in adult women under 65 years of age with IBS-C, following a thorough safety review by the FDA and an FDA-assembled Gastrointestinal Drugs Advisory Committee (GIDAC). The evaluation consisted of a review of clinical data from 29 placebo-controlled trials and post-marketing treatment outcome data.

“ZELNORM addresses an area of clear unmet medical need and there is a robust body of data supporting its safe and effective use when used as indicated for adult women in the U.S. suffering from IBS-C,” said John Kincaid M.D., head of medical affairs at Alfasigma USA.

ZELNORM is the only serotonin-4 (5-HT4) receptor agonist approved to treat IBS-C. It targets the 5-HT4 receptor at multiple neurons (sensory, motor, secretory motor) and smooth muscle cells in the gastrointestinal tract to induce contraction and relaxation, and decrease pain signaling.
