Ironwood Pharmaceuticals Provides Fourth Quarter 2010 Investor Update

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Ironwood Pharmaceuticals, Inc. (NASDAQ: IRWD) today provided an update on its recent and fourth quarter 2010 business activities.

Fourth Quarter 2010 and Recent Highlights


  • In November, Ironwood and its U.S. partner, Forest Laboratories, Inc., completed the clinical efficacy portion of the linaclotide development program to support upcoming regulatory submissions in both the U.S. and the E.U. Linaclotide met 66 out of 66 U.S. and E.U. primary and secondary endpoints in the four Phase 3 trials assessing its efficacy and safety in patients with irritable bowel syndrome with constipation (IBS-C) or chronic constipation (CC). Diarrhea was the most common adverse event in linaclotide‐treated patients in these trials.

    In the 26-week Phase 3 IBS-C trial, improvements in both abdominal pain and complete spontaneous bowel movements were achieved for linaclotide-treated patients in the first week of treatment, and these improvements were sustained throughout the entire period. Of particular note, at the 26th week of treatment, linaclotide-treated patients had a mean reduction in abdominal pain of 50 percent compared to 27 percent for placebo-treated patients (p
  • Ironwood and Forest are on track to submit a New Drug Application (NDA) for linaclotide with the U.S. Food and Drug Administration for both the IBS-C and CC indications in the third quarter of 2011.
  • Ironwood's European partner, Almirall, S.A., is on track to submit a Market Authorization Application (MAA) for linaclotide with the European Medicines Agency for the IBS‐C indication in the second half of 2011.
  • Ironwood and Forest were recently informed that all six linaclotide-related abstracts submitted for presentation at the 2011 Digestive Disease Week (DDW) annual meeting have been accepted. Four abstracts will be discussed in oral presentations and two will be made available through poster presentations. These presentations will be the first time that Ironwood and Forest discuss the full results of the two Phase 3 IBS-C clinical trials. These presentations will be made May 7—9, 2011 at the DDW annual meeting in Chicago.

Pipeline and Corporate

  • Ironwood continues to advance its pipeline, which includes product candidates and research efforts focused on gastrointestinal disease, pain and inflammation, respiratory and allergic disease, and cardiovascular disease. To augment its internal discovery capabilities, Ironwood recently initiated a collaboration with Protagonist Therapeutics, Inc. through which Protagonist will use its proprietary disulfide rich peptide technology platform to discover peptides against targets identified by Ironwood. Ironwood has the right to advance such peptides through preclinical and clinical development, and if such development is successful, commercialization.
  • Ironwood ended fiscal year 2010 with $248 million of cash, cash equivalents, and available-for-sale securities. Based on its current operating plan, Ironwood targets ending fiscal year 2011 with greater than $150 million of cash, cash equivalents, and available-for-sale securities.

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 has been shown to reduce visceral pain, increase fluid secretion, and accelerate 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. Linaclotide is in Phase 3 clinical development for the treatment of irritable bowel syndrome with constipation (IBS-C) and chronic constipation. The efficacy portion of linaclotide's development program has been completed and will support the NDA submission for both indications, as well as the MAA submission for the IBS-C indication. An issued composition of matter patent for linaclotide provides protection to 2025. Ironwood and Forest are co-developing and, if it is approved, will 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.

About Irritable Bowel Syndrome with Constipation (IBS-C)

IBS-C is a chronic functional gastrointestinal disorder characterized by abdominal pain, discomfort, and bloating associated with altered bowel habits, and as many as 11 million people in the U.S. suffer from it. There are currently few available therapies to treat this disorder and there is a high rate of dissatisfaction with available therapies. Patients suffering from IBS-C can be affected physically, psychologically, socially, and economically.

About Chronic Constipation (CC)

As many as 34 million Americans suffer from symptoms associated with CC and 8.5 million patients have sought treatment. Patients with CC often experience hard and lumpy stools, straining during defecation, a sensation of incomplete evacuation, and fewer than three bowel movements per week, as well as discomfort and bloating. This condition significantly affects patients' quality of life by impairing their ability to work and participate in typical daily activities. There is a high rate of dissatisfaction with currently available treatments.
