Ironwood Pharmaceuticals to Present New Data on Once-Weekly Apraglutide in Short Bowel Syndrome with Intestinal Failure (SBS-IF) at Digestive Disease Week® 2024
Ironwood Pharmaceuticals, Inc. (Nasdaq: IRWD) will present new data on once-weekly apraglutide in short bowel syndrome with intestinal failure (SBS-IF) at the 2024 Digestive Disease Week®. The pivotal Phase III STARS study's findings and the STARS Nutrition Study will be highlighted, alongside additional posters focusing on linaclotide, irritable bowel syndrome, and functional constipation. Apraglutide data from the STARS trial aims to reduce parenteral support (PS) dependency in adult SBS-IF patients, with plans for a new drug application submission to the FDA.
New data from the STARS Phase III trial on apraglutide shows promise in reducing PS dependency in SBS-IF patients, potentially offering a once-weekly GLP-2 analog treatment option.
The upcoming late-breaker oral presentation at DDW 2024 highlights the efficacy and safety of apraglutide, signaling positive results from the STARS study, leading to potential regulatory filings for approval.
Ironwood Pharmaceuticals' commitment to advancing GI-focused treatments is evidenced through the presentation of real-world insights in IBS-C and FC, portraying a holistic approach to digestive health.
While the new data presents encouraging results, the ultimate approval and market acceptance of apraglutide for SBS-IF treatment remain pending FDA review and other regulatory clearances, posing a potential risk.
The dependency of adult SBS-IF patients on PS and the need for new drug treatments highlight the severity of the condition and the high stakes associated with the effectiveness of apraglutide in reducing this dependency.
– Data from pivotal Phase III STARS study in short bowel syndrome with intestinal failure (SBS-IF) accepted as late-breaker oral presentation on May 21 at 10:30 am ET –
– Findings from the STARS Nutrition Study in SBS-IF will be highlighted in poster presentations –
– Additional posters will focus on linaclotide, irritable bowel syndrome with constipation and functional constipation –
SBS-IF, a rare chronic debilitating malabsorptive condition in which patients are dependent on PS, affects an estimated 18,000 adult patients in the
The late-breaker presentation includes new apraglutide data from the STARS Phase III trial. Based on these results, the company is working to submit a new drug application (NDA) to the
“Coming off our recently announced positive topline results from STARS, we’re excited to share additional study findings that underscore the importance of apraglutide as a potential once-weekly GLP-2 analog for adult patients with SBS who are dependent on parenteral support,” said Michael Shetzline, M.D., Ph.D., chief medical officer, senior vice president and head of research and drug development at Ironwood Pharmaceuticals. “We also look forward to showcasing additional real-world insights related to our IBS-C and FC linaclotide portfolio.”
In addition to the oral presentation, a series of four posters will highlight findings across the apraglutide development program. Also, three posters will spotlight data on linaclotide in adults with irritable bowel syndrome with constipation (IBS-C), disparities in IBS diagnosis, and real-world prescribing patterns for pediatric patients with functional constipation (FC) and IBS-C. A list of the data presentations is below.

About Apraglutide
Apraglutide is an investigational, synthetic GLP-2 analog being developed for a range of rare gastrointestinal diseases where GLP-2 can play a central role in addressing disease pathophysiology, including short bowel syndrome with intestinal failure (SBS-IF) and Acute Graft-Versus-Host Disease (aGVHD).
About LINZESS® (linaclotide)
LINZESS® is the #1 prescribed brand in the
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. LINZESS relieves constipation in children and adolescents aged 6 to 17 years with functional constipation. 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. In children with functional constipation aged 6 to 17 years, the recommended dose is 72 mcg.
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.

LINZESS Important Safety Information
INDICATIONS AND USAGE
LINZESS® (linaclotide) is indicated for the treatment of both irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC) in adults and functional constipation (FC) in children and adolescents 6 to 17 years of age. It is not known if LINZESS is safe and effective in children with FC less than 6 years of age or in children with IBS-C less than 18 years of age.
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
- 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 guanylate cyclase (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
Diarrhea
-
In adults, 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. -
In children and adolescents 6 to 17 years of age, diarrhea was the most common adverse reaction in 72 mcg LINZESS-treated patients in the FC double-blind placebo-controlled trial. Severe diarrhea was reported in <
1% of 72 mcg LINZESS treated patients. If severe diarrhea occurs, dosing should be suspended and the patient rehydrated.
Common Adverse Reactions (incidence ≥
- In IBS-C or CIC adult patients: diarrhea, abdominal pain, flatulence, and abdominal distension.
- In FC pediatric patients: diarrhea.
