Ironwood Pharmaceuticals, Inc. is a commercial‐stage biotechnology company focused on the discovery, development and commercialization of medicines for gastrointestinal (GI) disorders. The company’s flagship product is linaclotide, marketed under the brand name LINZESS in the United States for the treatment of irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC). Through a strategic collaboration with Allergan (now part of AbbVie), Ironwood also commercializes linaclotide in select ex-U.S. markets under the brand name CONSTELLA.
In addition to its marketed therapy, Ironwood maintains a diversified pipeline of clinical and preclinical programs targeting GI motility, inflammation and neurological conditions. Lead pipeline candidates include novel small molecules designed to modulate gut motility and secretions, as well as agents aimed at central nervous system targets to address pain and neurodegenerative disorders. The company leverages in-house research capabilities alongside external partnerships to advance its portfolio.
Founded in 1998 as Microbia Biosciences, the business rebranded as Ironwood Pharmaceuticals in 2010 concurrent with its initial public offering. Headquartered in Cambridge, Massachusetts, Ironwood conducts research and development activities in the U.S. and collaborates with global pharmaceutical partners to extend its reach into European, Canadian and other international markets.
Ironwood is led by President and Chief Executive Officer Peter Hecht, who brings extensive experience in both commercial operations and strategic development within the biopharmaceutical industry. Under his leadership, the company continues to pursue innovative therapies aimed at addressing unmet needs in GI health and related therapeutic areas.
