• If approved, linaclotide would be the first prescription therapy for functional constipation in children and adolescents 6 to 17 years of age 1
  • Submission is based on positive Phase 3 study data demonstrating linaclotide (72mcg) resulted in increases within frequency of spontaneous bowel movements (SBM) and improved stool consistency in kids and children aged 6 to 17 years

NORTH CHICAGO, Ill. , Dec. 16, 2022 /PRNewswire/ — AbbVie (NYSE: ABBV ) today announced that it has submitted a supplemental New Drug Application (sNDA) with regard to linaclotide (LINZESS®) to the U. H. Food and Medication Administration (FDA) for the treatment of children and adolescents 6 in order to 17 years old with functional constipation (FC). The sNDA submission is founded on results from a Phase 3 clinical trial, which met the particular primary and secondary endpoints, evaluating linaclotide (72 mcg) for increased frequency associated with spontaneous intestinal movements (SBM) and improvement in stool consistency in patients aged 6 to17 years.   LINZESS is developed plus marketed by AbbVie and Ironwood Pharmaceuticals in the United States and will be currently indicated for that therapy of adults with chronic idiopathic obstipation (CIC) or irritable bowel syndrome with constipation (IBS-C).

“Although practical constipation is common among pediatric patients, they have long been difficult to manage due to a lack of authorized prescription treatment options, ” said Celine Goldberger , MD, PhD, vice president, head of US medical affairs, AbbVie. “This milestone demonstrates our tireless work to advance the standards of care in order to make a difference in patients’ lives. ”

In the multicenter double-blind Stage 3 research evaluating LINZESS in patients 6 in order to 17 many years of age with useful constipation, the total associated with 330 patients were randomized in a 1: 1 ratio between linaclotide or even placebo. Linaclotide showed the statistically significant and clinically meaningful enhancement compared to placebo in 12-week SBM frequency rate (SBMs/week), the primary endpoint. Linaclotide-treated patients demonstrated a greater than two-fold least squares mean change through baseline within SBMs/week (2. 220) compared to placebo (1. 050) (p< 0. 0001).

The Phase 3 study demonstrated acceptable safety in the particular pediatric population. The most common adverse event in the pediatric Phase a few study was diarrhea which usually occurred in 4. 3% of linaclotide-treated patients versus 1. 8% in the placebo group.

FC inside children is defined as a condition along with hard, infrequent bowel movements that are often difficult or painful to pass. 2 FC is the common problem in kids of all ages, with a worldwide prevalence ranging between 0. 7% plus 29. 6%. three or more   Core symptoms of FC include decreased feces frequency, harder stool regularity, painful passage of stools, and fecal incontinence. 2

About Linaclotide  

Linaclotide is a guanylate cyclase-C (GC-C) agonist that is thought to work in two ways based on nonclinical studies. Linaclotide binds in order to the GC-C receptor locally within the particular intestinal epithelium. Activation of GC-C results in improved intestinal fluid secretion and accelerated transit and a decrease in the activity of pain-sensing nerves within the intestine. The medical relevance of the effect on pain fibers, which is based on nonclinical studies, has not been established. In the United States , Ironwood plus AbbVie co-develop and co-commercialize LINZESS® for your treatment associated with adults along with IBS-C or even CIC. Inside Europe , AbbVie markets linaclotide under the brand name CONSTELLA® for the treatment of adults with moderate to severe IBS-C. AbbVie is usually partnered along with Ironwood regarding the development and commercialization of linaclotide in all other territories worldwide.

LINZESS Important Safety Information  
LINZESS (linaclotide) is pointed out in grownups for that treatment of both irritable intestinal syndrome with constipation (IBS-C) and persistent idiopathic constipation (CIC).


LINZESS is contraindicated in individuals less than 2 years of age. In nonclinical studies in neonatal mice, administration of a single, medically relevant, adult oral dose of linaclotide caused deaths due to dehydration.  


  • LINZESS is contraindicated in patients less than 2 years of age group due to the risk of serious dehydration.
  • LINZESS is contraindicated in sufferers with known or suspected mechanical gastrointestinal obstruction.

Warnings and Precautions  
Pediatric Risk  

  • LINZESS is contraindicated in patients lower than two years old. In neonatal mice, linaclotide increased liquid secretion as a consequence of age-dependent elevated GC-C agonism resulting inside 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 yrs of age in order to assess the risk of developing diarrhea and its potentially serious consequences in these patients. The particular safety plus effectiveness associated with LINZESS inside patients much less than 18 years old have not been established.


  • 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 has been similar within the IBS-C and CIC populations. Severe diarrhea was reported in 2% of 145 mcg plus 290 mcg LINZESS-treated individuals, and in < 1% of 72 mcg LINZESS-treated CIC sufferers. 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% versus 1%).
  • In CIC tests of the 145 mcg dose: diarrhea (16% compared to 5% placebo), abdominal pain (7% vs 6%), flatulence (6% versus 5%), upper respiratory tract infection (5% compared to 4%), sinusitis (3% vs 2%) plus abdominal distension (3% versus 2%). Within a CIC trial of the 72 mcg dose: diarrhea (19% compared to 7% placebo) and stomach distension (2% vs < 1%).
