RESUMEN
Short bowel syndrome (SBS) is a clinical condition characterized by a failure to achieve optimal intestinal adaptation, which is necessary to maintain oral/enteral autonomy. At present, the treatment options for SBS are primarily intestinal replacement and rehabilitation. Intestinal rehabilitation mainly includes non-transplantation surgery and intestinal rehabilitation measures. In recent years, intestinal rehabilitation in patients with SBS using nutritional intestinal hormones, especially glucagon-like peptide-2 analogs, has made great progress. Many high-quality studies have provided evidence-based medical findings to support the development of clinical guidelines. This article reviews the latest research advancements regarding the use of glucagon-like peptide-2 analogs (teduglutide, glepaglutide, and apraglutide) in the treatment of SBS.

BACKGROUND: Apraglutide is a novel long-acting glucagon-like peptide-2 (GLP-2) analog designed for once-weekly subcutaneous dosing, with the potential to increase fluid and nutrient absorption by the remnant intestine of patients who have short bowel syndrome (SBS) with intestinal insufficiency (SBS-II) or intestinal failure (SBS-IF). This trial investigated the safety and effects on intestinal absorption of apraglutide in patients with SBS-II and SBS-IF. METHODS: In this open-label, phase 1 and 2 trial, adult patients with SBS-II (n = 4) or SBS-IF (n = 4) and a fecal output of ≥1500 g/day received once-weekly subcutaneous 5 mg apraglutide for 4 weeks. Safety was the primary end point. Secondary end points included change from baseline in intestinal absorption of wet weight (indicative of fluid absorption), electrolytes, and energy (by bomb calorimetry) measured by inpatient metabolic balance studies. RESULTS: Common treatment-related adverse events were decreased gastrointestinal (GI) stoma output (n = 6), stoma complications (n = 6), GI stoma complications (n = 5), nausea (n = 5), flatulence (n = 4), abnormal GI stoma output (n = 4), polyuria (n = 3), and abdominal pain (n = 3). The only treatment-related serious adverse event (experienced in one patient) was abdominal pain. Apraglutide significantly increased wet weight and energy absorption by an adjusted mean of 741 g/day (95% CI, 194 to 1287; P = 0.015) and 1095 kJ/day (95% CI, 196 to 1994; P = 0.024), respectively. Sodium and potassium absorption significantly increased by an adjusted mean of 38 mmol/day (95% CI, 3 to 74; P = 0.039) and 18 mmol/day (95% CI, 4 to 32; P = 0.020), respectively. CONCLUSION: Once-weekly 5 mg apraglutide was well tolerated in patients with SBS-II and SBS-IF and significantly improved the absorption of fluids, electrolytes, and energy.

BACKGROUND: Patients with short bowel syndrome (SBS) and distal-bowel resections lack neuroendocrine feedback regulations, potentially resulting in rapid gastrointestinal (GI) transit. The objective was to assess the efficacy of glepaglutide, a long-acting glucagon-like peptide-2 analog, on GI transit in patients with SBS. METHODS: In this single-center, double-blind, dose-finding, phase 2 trial, patients with SBS were randomly assigned to 3 treatments (0.1, 1, and 10 mg) in a 2-period crossover design. Each treatment period included 3 weeks of daily, subcutaneous glepaglutide injections separated by a washout period of 4-8 weeks. Endpoints were changes from baseline and included scintigraphy, wireless motility capsule (WMC, SmartPill Given Imaging, Ltd, Yokneam, Israel), and paracetamol absorption test. RESULTS: A total of 18 patients were randomized. In the 10-mg dose group (n = 9), glepaglutide significantly increased time to 10% gastric emptying (GE) of solids by 27 (4-50) minutes (adjusted mean [95% CI]), time to 50%GE of fluids by 40 (1-80) minutes, and time to 10% small bowel-emptying of solids by 21 (1-41) minutes. The WMC transit did not significantly change in any of the dose groups. The maximum paracetamol concentration significantly increased in the 10-mg dose group; however, the area under the curve remained the same. CONCLUSION: The prolonged GI transit after glepaglutide treatment, along with demonstrated positive effects on intestinal mucosal growth and potential effects on GI hypersecretions, is believed to contribute to the observed beneficial effects on fecal output (primary endpoint) and associated improvement in intestinal absorption.
