"Gattex is a ground-breaking therapy that has been evaluated in the largest clinical program to date in short bowel syndrome," said
SBS is a serious, complex disorder in which the body is unable to absorb enough nutrients and fluids through the gastrointestinal tract to sustain life. SBS patients are commonly infused with PN/IV five to seven nights per week for up to 10 to 12 hours at a time, and in extreme cases, some patients could receive PN/IV for 24 hours a day. Long-term use of PN/ IV fluids can be associated with life-threatening complications such as liver damage, serious bloodstream infections, and blood clots.
Gattex is the first major long-term treatment advance for SBS in nearly 40 years. The unique mechanism of action of Gattex enhances gastrointestinal absorption. In Phase 3 studies, significant reductions in PN/IV volume and infusion days per week were achieved from pre-treatment baseline. In addition, some patients achieved independence from PN/IV support.
"In addition to serious medical complications, patients with short bowel syndrome can have socially-restricted lives. Long infusion periods often disrupt sleep for patients. This is coupled with constant concern about using restrooms as many patients will need to use the bathroom up to 25 times a day or having an accident with unpredictable diarrhea. Other patients that have an ostomy bag have a fear of an ostomy bag leakage. These factors leave many patients unable to socialize or work," said
SBS typically occurs when a large portion of the intestine has been removed by surgery caused by disease or injury. In rare cases, it is congenital. Common symptoms of SBS can include diarrhea, dehydration, malnutrition, and weight loss, which are closely related to the functional issues of the bowel. During a typical day, SBS patients will move their bowels up to 10 times, or change their ostomy bag, which collects their urine output, three to four times. In extreme cases, patients may move their bowels as many as 25 times each day.
"Patients with short bowel syndrome/intestinal failure need a comprehensive program to receive optimal care so that their quality of life is maintained to its fullest extent.
To assist patients and healthcare professionals in facilitating care with Gattex, NPS has launched a free support program called NPS Advantage™. This program is designed to help navigate all aspects of care, help with insurance authorizations and appeals, answer questions about Gattex and its use, and locate resources for patients that connect them to care.
A key feature of NPS Advantage is the involvement of experienced care coordinators, who provide comprehensive support with a single point of contact. These NPS professionals will work with Gattex patients to confirm authorizations and benefit approvals for Gattex and help resolve health insurance issues. They will also support healthcare professionals to streamline the reimbursement process for Gattex and help their patients obtain appropriate medical care.

About Short Bowel Syndrome
Short bowel syndrome (SBS) is a highly disabling condition that can impair a patient's quality of life and lead to serious life-threatening complications. SBS typically arises after extensive resection of the bowel due to Crohn's disease, ischemia or other conditions. SBS patients often suffer from malnutrition, severe diarrhea, dehydration, fatigue, osteopenia, and weight loss due to the reduced intestinal capacity to absorb nutrients, water and electrolytes. The usual treatment for SBS is nutritional support, including parenteral nutrition (PN) and/or intravenous (IV) fluids to supplement and stabilize nutritional needs.
Although PN can provide nutritional support for SBS patients, it does not improve the body's own ability to absorb nutrients. PN is associated with serious complications, such as infections, blood clots or liver damage, and the risks increase the longer patients are on PN. Patients on PN often experience poor quality of life with difficulty sleeping, and frequent urination, and patients receiving chronic PN often experience a loss of independence.
Gattex Clinical Trials
NPS' clinical development program for Gattex is the largest and most comprehensive conducted in SBS patients to date, consisting of 15 clinical studies. Across all clinical studies, 566 subjects were exposed to at least one dose of Gattex, of whom 134 had SBS and were treated with 0.05 mg/kg/day Gattex. The
- In an intent-to-treat analysis at weeks 20 and 24, 63 percent of patients treated with Gattex achieved at least a 20 percent reduction in weekly PN/IV volume when compared to baseline, versus 30 percent for placebo (p=0.002).
- After 24 weeks of treatment, PN volume declined by 32 percent (4.4 L/wk) in Gattex-treated patients, versus 21 percent (2.3 L/wk) in the placebo group (p<0.001).
- After 24 weeks of treatment, 54 percent of Gattex-treated patients were able to reduce the number of infusion days per week by one or more days, compared to 23 percent of those treated with placebo (p=0.005).
The most common adverse reactions (≥10 percent) across all studies with Gattex are abdominal pain, injection site reactions, nausea, headaches, abdominal distension, upper respiratory tract infection. In addition, vomiting and fluid overload were reported in the Phase 3 SBS studies at rates ≥ 10 percent.

About Gattex® (teduglutide [rDNA origin]) for Injection
Gattex® (teduglutide [rDNA origin]) for Injection, for subcutaneous use is a novel, recombinant analog of human glucagon-like peptide 2, a protein involved in the rehabilitation of the intestinal lining. Gattex® 0.05 mg/kg/d (teduglutide [rDNA origin] for Injection) is indicated for the treatment of adult patients with short bowel syndrome (SBS) who are dependent on parenteral support. Significant reductions in mean PN/IV infusion volume from baseline to end of treatment were seen in the Phase 3 studies of Gattex. In addition, some patients were able to achieve independence from PN/IV support during these trials. The most common side effects of Gattex include stomach area (abdomen) pain or swelling, skin reaction where the injection was given, nausea, headache, cold or flu like symptoms, vomiting, and holding too much fluid in the body (swelling of face, ankles, hands or feet).

Important Safety Information (ISI)
Gattex has been associated with serious risks including:
- Neoplastic growth. There is a risk for acceleration of neoplastic growth. Colonoscopy of the entire colon with removal of polyps must be done before initiating treatment with Gattex and is recommended after 1 year. Subsequent colonoscopies should be done as needed, but no less frequently than every 5 years. In case of intestinal malignancy discontinue Gattex. The clinical decision to continue Gattex in patients with active non-gastrointestinal malignancy should be made based on risk and benefit considerations.
- Intestinal obstruction. In patients who develop obstruction, Gattex should be temporarily discontinued pending further clinical evaluation and management.
- Biliary and pancreatic disease. Patients should undergo laboratory assessment (bilirubin, alkaline phosphatase, lipase, amylase) before starting Gattex. Subsequent laboratory tests should be done every 6 months. If clinically meaningful changes are seen, further evaluation is recommended including imaging, and continued treatment with Gattex should be reassessed.
- Fluid overload. There is a potential for fluid overload while on Gattex. If fluid overload occurs, especially in patients with cardiovascular disease, parenteral support should be appropriately adjusted, and Gattex treatment reassessed.
Prescribers should select the appropriate patients to receive Gattex in accordance with the approved prescribing information, discuss the benefits and risks of Gattex with patients, and monitor patients as specified in the approved prescribing information and report adverse events to NPS' Gattex information line at 1-855-5GATTEX (1-855-542-8839) or event/product complaint line at 1-855-215-5550.
