Bottom line
Glepaglutide (ZP1848) is a long-acting GLP-2 receptor agonist modified with a C-terminal hexa-lysine tail for extended The time for the amount of a substance in the body to fall by half.

Fuente de la definición: Neutral gloss; usage context: Routes, devices, and absorption primer · Glosario dosing. Developed by Zealand Pharma, it is in phase 3 development (EASE program) for short bowel syndrome with intestinal failure (SBS-IF). The EASE-1 trial (NCT03690206) met its primary endpoint, showing a statistically significant reduction in parenteral support volume (−5.13 L/wk vs −2.85 L/wk An inactive comparator used in a controlled study.

Sport status: WADA: S0 — non-approved pharmacological substance. As an unapproved GLP-2 receptor agonist, glepaglutide falls under WADA S0 (any pharmacological substance not addressed by other sections of the Prohibited List and not approved by any governmental regulatory authority for human therapeutic use).
Mechanism and pharmacology
GLP-2 receptor agonist. Promotes intestinal mucosal growth and adaptation, enhances nutrient and fluid absorption, reduces gastric emptying and gastric acid secretion, increases intestinal blood flow. The C-terminal hexa-lysine sequence extends The time for the amount of a substance in the body to fall by half. Fuente de la definición: Neutral gloss; usage context: Routes, devices, and absorption primer · Glosario compared to native GLP-2, enabling less frequent dosing. In the EASE-1 trial, glepaglutide twice weekly showed improvement across major SBS anatomic subgroups (jejunostomy, jejunoileal anastomosis, and colon-in-continuity).
