GATTEX Has a Demonstrated Safety Profile in Pediatric Patients1
In 2 clinical studies, 41 pediatric patients were treated with GATTEX 0.05 mg/kg/day
Overall, the safety profile of GATTEX in pediatric patients ≥1 year was similar to that in adults1
The 41 patients included 1 infant (1 year to less than 2 years), 37 children (2 years to less than 12 years), and 3 adolescents (12 years to less than 17 years)1
In the long-term extension studies with a mean exposure of 41 weeks, no new safety signals were identified1

If patients have a stoma, advise them that while they may experience abdominal pain and swelling of their stoma, especially when starting treatment with GATTEX, if they experience symptoms of intestinal obstruction, they should contact their physician1
Among the 53 patients with stoma in the placebo-controlled studies, 42% (13/31) of patients with gastrointestinal stoma complication received GATTEX 0.05 mg/kg/day and 14% (3/22) received placebo1

Monitoring Timeline for Pediatric Patients Receiving GATTEX
Within 6 months prior to starting GATTEX treatment1:
- Perform fecal occult blood testing; if there is unexplained blood in the stool, perform colonoscopy/sigmoidoscopy and an upper GI endoscopy1
- Obtain baseline laboratory assessments (bilirubin, alkaline phosphatase, lipase, and amylase)1
Monitoring timeline | Ongoing/ as needed | Every 6 months | After 1 year of GATTEX* | Every year |
At least every 5 years |

††Colonoscopy/sigmoidoscopy is recommended for all children and adolescents after 1 year of treatment, every 5 years thereafter while on continuous treatment with GATTEX, and if they have new or unexplained gastrointestinal bleeding.1
‡‡Consider upper GI endoscopy (or alternate other imaging) during treatment with GATTEX. If there is new or unexplained blood in the stool, perform colonoscopy/sigmoidoscopy and an upper GI endoscopy.1
Observation of other adverse events
Discontinuation of treatment with GATTEX may result in fluid and electrolyte imbalance. Fluid and electrolyte status should be monitored in patients who discontinue treatment with GATTEX.1
