Key takeaways
- Teduglutide is a GLP-2 analog approved for short bowel syndrome in people aged 1 year and older who depend on parenteral support 1.
- In the STEPS trial in adults, 63% versus 30% achieved more than 20% reduction in weekly parenteral support volume at weeks 20 and 24 3.
- Because of its growth-promoting action and rodent tumor findings, the label warns of possible acceleration of neoplastic growth and requires colonoscopy and upper GI endoscopy before and during treatment in adults 1.
- Other label warnings include intestinal obstruction, gallbladder, biliary and pancreatic disease, fluid overload including heart failure, and increased absorption of oral medicines 1.
- Teduglutide is not named in the 2026 Prohibited List text reviewed 4.
Development stage
Where Teduglutide sits between laboratory work and regulatory approval.
- PreclinicalAnimal and cell work
- Phase 1First human safety studies
- Phase 2Early efficacy signal
- Phase 3Confirmatory trials
- Approved (current)Cleared by a regulator
Stage comes from the regulatory record and ClinicalTrials.gov studies naming the compound (for compounds approved nowhere, only completed trials or trials with posted results count) (checked 2026-10-24). A registered trial is not a result.
Mechanism of action
Teduglutide is an analog of GLP-2, a peptide secreted by L-cells of the distal intestine that increases intestinal and portal blood flow and inhibits gastric acid secretion 1.
Receptor actions
It binds GLP-2 receptors on intestinal enteroendocrine cells, subepithelial myofibroblasts and enteric neurons, leading to local release of IGF-1, nitric oxide and keratinocyte growth factor 1.
Clinical correlate
In STEPS, teduglutide raised plasma citrulline, a biomarker of mucosal mass, alongside reductions in parenteral support 3.

Research overview
Human research
Two 24-week randomized, double-blind, placebo-controlled trials in adults with SBS (Study 1/STEPS, n = 86; Study 3, n = 84 across three groups) and their extensions support the label, along with 24-week and 12-week pediatric studies in 41 children aged 1 to under 17 years 1,3.
Animal research
In 2-year subcutaneous studies, teduglutide increased adenomas in the bile duct and jejunum of male rats and papillary gallbladder adenomas in mice, with jejunal adenocarcinomas in male mice at the high dose 1.
In-vitro research
Not reviewed separately for this entry.
Key studies
- Randomized, double-blind, placebo-controlled, 24 weeksModel: Humans (86 adults with SBS and intestinal failure)
Responders 63% versus 30% (P = .002); mean parenteral support reduction 4.4 versus 2.3 L/week; 54% versus 23% gained at least one day off per week 3.
- Open-label and blinded uncontrolled extensionsModel: Humans (adults with SBS)
Of 30 patients completing 30 months, 93% had at least 20% reduction in parenteral support and 10 were weaned off; in Study 4, 75% of earlier responders sustained response at 1 year 1.
- 24-week and 12-week studies with extensionsModel: Humans (41 children aged 1 to under 17 with SBS)
Safety profile similar to adults; anti-teduglutide antibodies in 54% at month 12 versus 24% in adults 1.
Dosing as stated on the FDA label
Quoted from the prescribing information for reference. Prescribing decisions belong to a licensed clinician; this is not a recommendation or instruction for use.
Full dosing reference, study durations and vial arithmetic →- Short bowel syndrome dependent on parenteral support (GATTEX): 0.05 mg/kg subcutaneously once daily for adults and pediatric patients aged 1 year and older 1.
- Moderate or severe renal impairment or end-stage renal disease (eGFR below 60 mL/min/1.73 m2): 0.025 mg/kg once daily 1.
- The label requires baseline colonoscopy and upper GI endoscopy with polyp removal (adults) or fecal occult blood testing (children) within 6 months before starting, plus bilirubin, alkaline phosphatase, lipase and amylase at baseline and every 6 months 1.
- Twice the recommended dose (0.1 mg/kg/day), tested in Study 3, is not a recommended dosage per the label 1.

Regulatory status
- Status
- FDA-approved as GATTEX (NDA 203441, original approval December 21, 2012) for adults and pediatric patients 1 year of age and older with short bowel syndrome who are dependent on parenteral support; label reviewed from the September 18, 2025 DailyMed version 1,2.
- United States (FDA)
- FDA-approved under NDA 203441 (GATTEX KIT, Takeda), original approval December 21, 2012 per Drugs@FDA 2; current indication per the September 2025 label covers adults and children aged 1 year and older with SBS dependent on parenteral support 1.
- Sport (WADA)
- Teduglutide is not named in the 2026 Prohibited List text reviewed; as an approved drug it is outside S0, but S2.3 covers other growth factors or modulators affecting tissue regenerative capacity, so status should be confirmed with the relevant anti-doping organization 4.
Status varies by country and changes over time. How we describe regulatory status.
Quality and testing notes
Identity can be confirmed against the 33-residue sequence with Gly at position 2 (PubChem formula C164H252N44O55S, MW about 3752) by mass spectrometry, with HPLC purity, host-cell protein and endotoxin testing for recombinant material [1, 5].
