LINZESS (linaclotide) is indicated in adults for the treatment of both irritable bowel syndrome
with constipation (IBS-C) and chronic idiopathic constipation (CIC).1

In Trial 6, a 12-week study of overall abdominal symptoms in IBS-C patients, LINZESS showed significant improvement vs placebo1,2*

Improvement in overall abdominal symptoms vs placebo was observed
at Week 1 and continued to improve through 12 weeks1

Abdominal scores at baseline: 6.4 for LINZESS and 6.5 for placebo. Least squares 12-week mean change from baseline: -1.9 for LINZESS and -1.2 for placebo.

*As measured by the composite abdominal score.

Based on responses to the following questions: How would you rate your worst abdominal bloating, your worst abdominal pain, and your worst abdominal discomfort in the past 24 hours?

The adverse event profile was consistent with the pivotal trials.

STUDY DESIGN: A randomized, double-blind, placebo-controlled, parallel-group study (N=614) to evaluate the efficacy on overall combined abdominal symptoms (abdominal bloating, abdominal pain, and abdominal discomfort) and safety of linaclotide 290 mcg administered orally to adult patients with irritable bowel syndrome with predominant constipation (IBS-C). The study comprised a 12-week treatment period and a 4-week randomized withdrawal period (post-treatment). The primary endpoint was the change from baseline in the multicomponent abdominal score throughout the treatment period, which is based on the mean abdominal score across treatment weeks obtained using the average daily assessments of abdominal bloating, abdominal pain, and abdominal discomfort. Each abdominal symptom was rated on a 0-to-10-point numeric rating scale (NRS) where 0=no [symptom] and 10=worst possible [symptom].

Discomfort

Because these individual component analyses were not adjusted for multiplicity, individual component results need cautious interpretation and could represent chance findings.

34% of patients in the LINZESS arm experienced a clinically meaningful reduction in overall abdominal symptoms vs 18.5% in the placebo arm1II

||Secondary endpoint. A responder showed at least a 2.5-point improvement in the abdominal score from baseline for at least 6 out of 12 weeks.1

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. 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 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%).
LINZESS® (linaclotide) is indicated in adults for the treatment of both irritable bowel syndrome with constipation (IBS‑C) and chronic idiopathic constipation (CIC).
