Enteral Autonomy and Days Off Parenteral Support With Teduglutide Treatment for Short Bowel Syndrome in the STEPS Trials.

Abstract

BackgroundTeduglutide response, in terms of parenteral support (PS) volume reduction, is associated with specific disease characteristics among adults with short bowel syndrome–associated intestinal failure (SBS‐IF). Whether these associations apply to PS weaning with teduglutide is unknown.MethodsAdults with SBS‐IF treated with teduglutide in the phase III STEPS study and open‐label extensions STEPS‐2 and STEPS‐3 were included in the analysis. Patients required PS ≥ 3 times weekly for ≥ 12 months at enrollment. The study population was stratified 3 times to create 3 distinct analysis populations based on bowel anatomy, etiology, and baseline PS volume. Outcomes included characteristics of patients who achieved PS independence and total and percentage of patients who had ≥ 1, ≥ 2, and ≥ 3 d/wk off PS at the end of STEPS, STEPS‐2, and STEPS‐3.ResultsEight of 39 patients who received teduglutide in STEPS obtained PS independence during the STEPS study series. Patients required > 6 months of teduglutide treatment before enteral autonomy was achieved, regardless of underlying disease characteristics. Patients who attained PS independence and greater numbers of days per week off PS tended to have lower baseline PS volumes and noninflammatory bowel disease (non‐IBD) etiology. Patients with ≥ 50% colon‐in‐continuity showed a trend for achieving greater numbers of days per week off PS.ConclusionAlthough this analysis was limited by low patient numbers, results suggest that SBS‐IF characteristics of lower baseline PS volume and non‐IBD etiology were associated with PS reduction benefits with teduglutide in terms of days off per week and enteral autonomy.
