Routes & formulations
Studied / approved routes
The approved product is a daily subcutaneous injection under its label.
Route availability is not evidence of efficacy, and evidence from one route does not transfer to another. The Registry never provides dosing or sourcing information.

What it is
A synthetic analogue of GLP-2, the gut hormone that promotes intestinal growth and absorption — engineered to resist rapid breakdown.
What people claim
- Reduces parenteral nutrition dependence in short bowel syndrome
What the evidence actually says
Randomised controlled trials demonstrated reduced parenteral-support requirements in short bowel syndrome. It is also a standing illustration of this registry's core point: GLP-2 is not GLP-1, and the incretin family's name similarity causes real confusion.
Human evidence
- Randomised, placebo-controlled trials in parenteral-support-dependent short bowel syndrome.
Preclinical evidence
- GLP-2 receptor biology and intestinal-adaptation models.
Animal and cell findings are Level 1–2 evidence.
Mechanism and pathways
- GLP-2 receptor agonism promotes intestinal mucosal growth and nutrient absorption.
Safety and unknowns
- The label carries a warning about potential acceleration of neoplastic growth and requires colonoscopic surveillance — a monitored, labelled risk.
- Gastrointestinal obstruction and fluid-overload events are also labelled considerations.
Cancer relevance
Monitored in trials; not demonstrated in humans
Regulatory status
FDA-approved (Gattex) for adults and paediatric patients with short bowel syndrome who are dependent on parenteral support. Approval is specific to that orphan indication.
Evidence grade
Replicated large randomised trials, pivotal Phase 3 programmes, or a major regulatory decision.
What would change our rating?
- Long-term registry data on the labelled neoplasia surveillance question.

Source hierarchy: regulatory documents and trial registries first, peer-reviewed work next, sponsor material flagged as non-independent. We never use supplier or clinic marketing as evidence, and where a verified source has not yet been curated we say so rather than inventing one.
