Ironwood Pharmaceuticals Provides Fourth Quarter 2011 Investor Update

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Ironwood Pharmaceuticals, Inc. (NASDAQ: IRWD) today provided an update on its fourth quarter 2011 and recent business activities.

"During 2011, we were focused on preparing linaclotide for successful regulatory submissions in the U.S. and Europe, and we continue to put all of the elements in place for a successful product launch while these submissions are under review, including our recent capital raise of $85 million to strengthen our balance sheet," said Michael Higgins, Ironwood's chief operating officer and chief financial officer. "We believe that linaclotide's product profile is highly appealing for both therapy-seeking patients and physicians and we are committed to a successful product launch, if approved."

Fourth Quarter and Recent Highlights


  • On February 8, Ironwood was informed that the U.S. Food and Drug Administration (FDA) will not schedule an advisory committee meeting in connection with its review of the New Drug Application (NDA) for linaclotide for the treatment of irritable bowel syndrome with constipation (IBS-C) and chronic constipation (CC). Under the FDA's Prescription Drug User Fee Act (PDUFA), the companies anticipate action by the FDA in June 2012.
  • Fourteen linaclotide-related abstracts have been accepted for presentation during the 2012 Digestive Disease Week (DDW) annual meeting that will be held in San Diego from May 19—22, 2012. One abstract will be discussed in an oral presentation and 13 will be made available through poster presentations.


  • Ironwood continues to advance its pipeline, which includes early development candidates and discovery efforts focused on gastrointestinal disease, central nervous system disorders, and respiratory disease.
  • In January 2012, Ironwood announced that it entered into a collaboration, research, and licensing agreement for the development and commercialization of Bionomics' investigational anti-anxiety compound BNC210 (renamed as IW-2143) and other related compounds. Ironwood will be responsible for worldwide development and commercialization of all products incorporating IW-2143 or other licensed compounds, including funding of clinical trials. Over the next 24 months, Bionomics may receive up to $13 million in research funding and milestone payments, which includes an initial payment of $3 million.


  • Ironwood ended 2011 with approximately $164 million of cash, cash equivalents, and available-for-sale securities. Ironwood used approximately $75 million of net cash for operations for the year ended December 31, 2011.
  • In February 2012, Ironwood sold 6,037,500 shares of its Class A common stock through a firm commitment, underwritten public offering at a price to the public of $15.09 per share. As a result of the offering, Ironwood received aggregate net proceeds, after underwriting discounts and commissions and other estimated offering expenses, of approximately $85 million. Ironwood intends to use these proceeds for general corporate purposes, including to fund expenses related to the expected market launch of linaclotide (if approved).
  • In February, the Massachusetts Life Sciences Center awarded Ironwood tax incentives of $1.8 million based upon Ironwood's plan to increase its Massachusetts-based employees by 75 by the end of 2012.

About Linaclotide

Linaclotide, an investigational drug, is an agonist of the guanylate cyclase type-C (GC-C) receptor located on the luminal surface of the intestine. In preclinical models, linaclotide reduced visceral hypersensitivity, increased fluid secretion, and accelerated intestinal transit. The effects on secretion and transit are mediated through cyclic guanosine monophosphate (cGMP), which is also believed to modulate the activity of local nerves to reduce pain. Linaclotide is an orally delivered peptide that acts locally in the gut with no measurable systemic exposure at therapeutic doses and is intended for once-daily administration. An issued composition of matter patent for linaclotide provides protection to 2025 in the United States. Ironwood and Forest plan to co-promote linaclotide in the United States. Ironwood has out-licensed linaclotide to Almirall for European development and commercialization, and to Astellas Pharma Inc. for development and commercialization in Japan, Indonesia, Korea, the Philippines, Taiwan, and Thailand.
