Ironwood and Forest Announce U.S. Availability of LINZESS™ (Linaclotide)
- New Treatment for Adults with Irritable Bowel Syndrome with Constipation or
Chronic Idiopathic Constipation Now in Pharmacies Across the U.S.-
CAMBRIDGE, Mass. & NEW YORK -- December 17, 2012
Ironwood Pharmaceuticals, Inc. (NASDAQ: IRWD) and Forest Laboratories, Inc.
(NYSE: FRX) announced today that LINZESS™ (linaclotide) is now available in
pharmacies throughout the United States. The U.S. Food and Drug Administration
(FDA) recently approved LINZESS as a once-daily oral capsule for adult men and
women suffering from irritable bowel syndrome with constipation (IBS-C) or
chronic idiopathic constipation (CIC).
LINZESS is the first and only FDA-approved guanylate cyclase-C (GC-C) agonist
and acts locally in the intestine. For the first time in over six years, a new
prescription option is available for adults with these disorders.
Visit www.linzess.com for more information about LINZESS.
LINZESS is the first and only guanylate cyclase-C (GC-C) agonist approved by
the FDA for the treatment of both irritable bowel syndrome with constipation
(IBS-C) and chronic idiopathic constipation (CIC) in adults. LINZESS is a
once-daily capsule that helps relieve the abdominal pain and constipation
associated with IBS-C and constipation and hard stools associated with CIC.
The recommended dose is 290 mcg for IBS-C patients and 145 mcg for CIC
patients. LINZESS should be taken at least 30 minutes before the first meal of
LINZESS is thought to work in two ways based on nonclinical studies. LINZESS
binds to the GC-C receptor locally, within the intestinal epithelium.
Activation of GC-C results in increased intestinal fluid secretion and transit
and a reduction in visceral pain, which is thought to be mediated by decreased
activity of pain-sensing nerves. The clinical relevance of the effect on pain
fibers in nonclinical studies has not been established.
In placebo-controlled Phase III clinical trials of more than 2,800 adults,
LINZESS was shown to reduce abdominal pain in IBS-C patients and increase
bowel movement frequency in both IBS-C patients and CIC patients. Improvement
in abdominal pain and constipation occurred in the first week of treatment and
was maintained throughout the 12-week treatment period. Maximum effect on
abdominal pain was seen at weeks 6-9 and maximum effect on constipation
occurred during the first week. When a subset of LINZESS-treated patients in
the trials were switched to placebo, they reported their symptoms returned
toward pretreatment levels within one week, while placebo-treated patients
switched to LINZESS reported symptom improvements. LINZESS is contraindicated
in pediatric patients up to 6 years of age. The use of LINZESS in pediatric
patients 6 through 17 years of age should be avoided. In nonclinical studies,
administration of a single, clinically relevant adult oral dose of linaclotide
caused deaths in young juvenile mice. LINZESS has not been studied in
pediatric patients. In adults with IBS-C or CIC treated with LINZESS, the most
commonly reported adverse event was diarrhea.
Ironwood and Forest are co-promoting LINZESS in the United States. Linaclotide
was also approved recently by the European Commission for the treatment of
adults in the European Union with IBS-C and will be marketed under the brand
name Constella® through a license agreement between Ironwood and Almirall,
S.A. Ironwood also has partnered linaclotide with Astellas Pharma Inc. for
development and commercialization in Japan and certain other Asian countries
and with AstraZeneca for development and commercialization in China.
About Irritable Bowel Syndrome with Constipation
Irritable bowel syndrome with constipation (IBS-C) is a chronic functional
gastrointestinal disorder that affects as many as 13 million people in the
United States. IBS-C can have a negative impact on daily living; patients
often experience recurring abdominal pain or discomfort, constipation, and
bowel symptoms including hard or lumpy stools in more than 25% of bowel
movements, and soft or watery stools in less than 25% of bowel movements.
There are currently few available therapies approved to treat this disorder.
About Chronic Idiopathic Constipation
Chronic idiopathic constipation (CIC) is a functional gastrointestinal
disorder in which individuals experience infrequent bowel movements (less than
three times per week) for at least three months. Patients who suffer from CIC
may also experience a sensation of incomplete evacuation and hard stools. As
many as 35 million Americans may suffer from symptoms associated with CIC.
Important Safety Information
WARNING: PEDIATRIC RISK
LINZESS is contraindicated in pediatric patients up to 6 years of age. Use
should be avoided in pediatric patients 6 through 17 years of age. In
nonclinical studies, administration of a single, clinically relevant adult
oral dose of linaclotide caused deaths in young juvenile mice.
*LINZESS is contraindicated in pediatric patients up to 6 years of age.
*LINZESS is contraindicated in patients with known or suspected mechanical
Warnings and Precautions
*LINZESS is contraindicated in pediatric patients up to 6 years of age. In
nonclinical studies, deaths occurred within 24 hours in young juvenile
mice (1 to 3 week-old mice; approximately equivalent to human pediatric
patients less than 2 years of age) following administration of one or two
daily oral doses of linaclotide.
*Use of LINZESS should be avoided in pediatric patients 6 through 17 years
of age. Linaclotide did not cause deaths in older juvenile mice
(approximately equivalent to humans age 12 to 17 years). Although there
were no deaths in older juvenile mice, given the deaths in young juvenile
mice and the lack of clinical safety and efficacy data in pediatric
patients, use of LINZESS should be avoided in pediatric patients 6 through
17 years of age.
*Diarrhea was the most common adverse reaction of LINZESS-treated patients
in the pooled IBS-C and CIC double-blind placebo-controlled trials. Severe
diarrhea was reported in 2% of LINZESS-treated patients. The incidence of
diarrhea was similar in the IBS-C and CIC populations.
*Patients should be instructed to stop LINZESS if severe diarrhea occurs
and to contact their healthcare provider, who should consider dose
*In IBS-C clinical trials, the most common adverse reactions in
LINZESS-treated patients (incidence ≥2% and greater than placebo) were
diarrhea (20% vs 3% placebo), abdominal pain (7% vs 5%), flatulence (4% vs
2%), headache (4% vs 3%), viral gastroenteritis (3% vs 1%) and abdominal
distension (2% vs 1%).
*In CIC clinical trials, the most common adverse reactions in
LINZESS-treated patients (incidence ≥2% and greater than placebo) were
diarrhea (16% vs 5% placebo), abdominal pain (7% vs 6%), flatulence (6% vs
5%), upper respiratory tract infection (5% vs 4%), sinusitis (3% vs 2%)
and abdominal distension (3% vs 2%).
No drug-drug interaction studies have been conducted with LINZESS. Linaclotide
and its active metabolite are not measurable in plasma following
administration of the recommended clinical doses; hence, no systemic drug-drug
interactions or drug interactions mediated by plasma protein binding of
linaclotide or its metabolite are anticipated
Linaclotide does not interact with the cytochrome P450 enzyme system based on
the results of in vitro studies. In addition, linaclotide is neither a
substrate nor an inhibitor of the efflux transporter P-glycoprotein (P-gp).
