At a glance
What is it—and why does it matter?
GATTEX contains teduglutide, a 33–amino acid analog of human GLP-2 produced via recombinant DNA technology in a modified Escherichia coli strain. As a GLP-2 analog, teduglutide engages GLP-2 receptors expressed in intestinal enteroendocrine cells, subepithelial myofibroblasts, and enteric neurons, consistent with an intestinal mechanism of action. Teduglutide treatment has reports of intestinal obstruction from both clinical trials and postmarketing surveillance. Recommended teduglutide dosing is weight-based (0.05 mg/kg) with once-daily subcutaneous administration.
