(NASDAQ: IRWD), a GI-focused healthcare company, today announced that the U.S. Food and Drug Administration (FDA) approved a revised label for LINZESS® (linaclotide) based on clinical safety data that has been generated thus far in pediatric studies. The updated label modifies the boxed warning for risk of serious dehydration and contraindication against use in children to those less than two years of age. The boxed warning and contraindication previously applied to all children less than 18 years of age and less than 6 years of age, respectively. The safety and effectiveness of LINZESS in patients less than 18 years of age have not been established. LINZESS is indicated in adults for the treatment of irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC). “The warning on the LINZESS label at launch was primarily applied due to preclinical findings, and there was an absence of any clinical data in pediatric populations at the time,” said Michael Shetzline, M.D., Ph. D, chief medical officer, senior vice president and head of drug development at Ironwood. “Since approval, we have worked diligently on generating clinical data to better characterize the safety profile for pediatric populations. This label update reflects a significant milestone, and we look forward to continuing to investigate the safety and efficacy of LINZESS for children.” The LINZESS prescribing information continues to include a boxed warning for children less than 2 years of age and a contraindication against use in this population. Further clinical data are also required to establish the safety and efficacy of LINZESS in the pediatric population (less than 18 years of age). Diarrhea, including severe diarrhea, is a potentially serious side effect of LINZESS. The approved revision to the boxed warning and the safety information of LINZESS in children is based on pediatric clinical safety data, including: Clinical studies that enrolled patients with functional constipation (FC) and those with irritable bowel syndrome with constipation (IBS-C); as well as clinical study data in children with FC Data from a human guanylate-cyclase (GC-C) expression study in pediatric subjects. LINZESS is a GC-C agonist Post-marketing data from the LINZESS global safety database in children who took LINZESS An analysis of the IBM® MarketScan® Database assessing the use of LINZESS in pediatric patients from the United States and Safety and efficacy results from a retrospective review of children at the Nationwide Children’s Hospital in Columbus, Ohio1 with FC or IBS-C who had taken LINZESS. About LINZESS (linaclotide) LINZESS® is the #1 prescribed brand in the U.S. for the treatment of adult patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC), based on IQVIA data. LINZESS is a once-daily capsule that helps relieve the abdominal pain, constipation and overall abdominal symptoms of bloating, discomfort and pain associated with IBS-C, as well as the constipation, infrequent stools, hard stools, straining and incomplete evacuation associated with CIC. The recommended dose is 290 mcg for IBS-C patients and 145 mcg for CIC patients, with a 72-mcg dose approved for use in CIC depending on individual patient presentation or tolerability. LINZESS should be taken at least 30 minutes before the first meal of the day. LINZESS is contraindicated in pediatric patients less than 2 years of age. In neonatal mice, linaclotide increased fluid secretion as a consequence of age-dependent elevated guanylate cyclase-C (GC-C) agonism which was associated with increased mortality within the first 24 hours due to dehydration. There was no age-dependent trend in GC-C intestinal expression in a clinical study of children 2 to less than 18 years of age; however, there are insufficient data available on GC-C intestinal expression in children less than 2 years of age to assess the risk of developing diarrhea and its potentially serious consequences in these patients. The safety and effectiveness of LINZESS in pediatric patients less than 18 years of age have not been established. In adults with IBS-C or CIC treated with LINZESS, the most commonly reported adverse event was diarrhea. LINZESS is not a laxative; it is the first medicine approved by the FDA in a class called GC-C agonists. LINZESS contains a peptide called linaclotide that activates the GC-C receptor in the intestine. Activation of GC-C is thought to result in increased intestinal fluid secretion and accelerated transit and a decrease in the activity of pain-sensing nerves in the intestine. The clinical relevance of the effect on pain fibers, which is based on nonclinical studies, has not been established. In the United States, Ironwood and AbbVie co-develop and co-commercialize LINZESS for the treatment of adults with IBS-C or CIC. In Europe, AbbVie markets linaclotide under the brand name CONSTELLA® for the treatment of adults with moderate to severe IBS-C. In Japan, Ironwood's partner Astellas markets linaclotide under the brand name LINZESS for the treatment of adults with IBS-C or CIC. Ironwood also has partnered with AstraZeneca for development and commercialization of LINZESS in China, and with AbbVie for development and commercialization of linaclotide in all other territories worldwide. LINZESS Important Safety Information INDICATIONS AND USAGE LINZESS is indicated in adults for the treatment of: irritable bowel syndrome with constipation (IBS-C) chronic idiopathic constipation (CIC) IMPORTANT SAFETY INFORMATION WARNING: RISK OF SERIOUS DEHYDRATION IN PEDIATRIC PATIENTS LESS THAN 2 YEARS OF AGE LINZESS is contraindicated in patients less than 2 years of age. In nonclinical studies in neonatal mice, administration of a single, clinically relevant adult oral dose of linaclotide caused deaths due to dehydration. Contraindications LINZESS is contraindicated in patients less than 2 years of age due to the risk of serious dehydration. LINZESS is contraindicated in patients with known or suspected mechanical gastrointestinal obstruction. Warnings and Precautions Risk of Serious Dehydration in Pediatric Patients Less Than 2 Years of Age LINZESS is contraindicated in patients less than 2 years of age. In neonatal mice, linaclotide increased fluid secretion as a consequence of age-dependent elevated GC-C agonism which was associated with increased mortality within the first 24 hours due to dehydration.

The safety and effectiveness of LINZESS in patients less than 18 years of age have not been established. Diarrhea Diarrhea was the most common adverse reaction in LINZESS-treated patients in the pooled IBS-C and CIC double-blind placebo-controlled trials. The incidence of diarrhea was similar in the IBS-C and CIC populations. Severe diarrhea was reported in 2% of 145 mcg and 290 mcg LINZESS-treated patients, and in <1% of 72 mcg LINZESS-treated CIC patients. If severe diarrhea occurs, dosing should be suspended and the patient rehydrated. Common Adverse Reactions (incidence ≥2% and greater than placebo) In IBS-C clinical trials: 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 trials of a 145 mcg dose: 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%). In a CIC trial of a 72 mcg dose: diarrhea (19% vs 7% placebo) and abdominal distension (2% vs <1%).
