CAMBRIDGE, Mass. & NEW YORK--(BUSINESS WIRE)--
Ironwood Pharmaceuticals, Inc. (NASDAQ: IRWD) and Forest Laboratories,
Inc. (NYSE: FRX) today announced that the U.S. Food and Drug
Administration (FDA) has accepted for review the New Drug Application
(NDA) for linaclotide for the treatment of irritable bowel syndrome with
constipation (IBS-C) and chronic constipation (CC). With a standard
10-month review timeline, the FDA Prescription Drug User Fee Act (PDUFA)
target action date is expected to occur in June 2012.
The companies submitted the NDA for linaclotide for the treatment of
IBS-C and CC based upon efficacy and safety results from a Phase 3
program comprising four double-blind placebo-controlled trials and two
open-label long term safety studies. A total of more than 2,800 patients
received a once-daily dose of either linaclotide or placebo across the
four clinical trials: two trials in patients with IBS-C and two trials
in patients with CC. Additionally, over 3,200 patients have enrolled in
ongoing open-label safety trials and more than 2,000 of those patients
have received linaclotide for at least 12 months.
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 U.S. 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, abdominal discomfort, and bloating associated with
altered bowel habits, and as many as 11 million people in the U.S.
suffer from it. IBS-C can have a negative impact on daily living. There
are currently few available therapies to treat this disorder.
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 abdominal discomfort and bloating. There is a high
rate of dissatisfaction with currently available treatments for CC.
