Ironwood Pharmaceuticals (Nasdaq: IRWD), an S&P SmallCap 600® company, is a leading gastrointestinal (GI) healthcare company on a mission to advance the treatment of GI diseases and redefine the standard of care for GI patients. We are pioneers in the development of LINZESS® (linaclotide), the U.S. branded prescription market leader for adults with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC). In June 2023, the U.S. Food and Drug Administration also approved LINZESS for the treatment of functional constipation in pediatric patients ages 6-17 years-old. Under the guidance of our seasoned industry leaders, we continue to build upon our history of GI innovation and challenge what has been done before to shape what the future holds. We keep patients at the heart of our R&D and commercialization efforts to reduce the burden of GI diseases and address significant unmet needs. Founded in 1998, Ironwood Pharmaceuticals is headquartered in Boston, Massachusetts. We routinely post information that may be important to investors on our website at www.ironwoodpharma.com.
