Background

Ulimorelin is a novel small molecule ghrelin agonist being developed by Tranzyme Pharma as a first-in-class treatment for both POI and diabetic gastroparesis, serious medical conditions in which motility of the GI tract is severely impaired.

Pharmacodynamics

Data gathered thus far demonstrate that Ulimorelin induces a dose-dependent increase of gastric emptying that effectively reverses the delay caused by surgically induced postoperative ileus (POI). Treatment levels as low as 30µg/kg have been shown to be effective in stimulating GI transit in this model. Furthermore, Ulimorelin significantly stimulates gastric emptying in naïve rats with 100-fold greater potency than metoclopramide, a compound currently marketed as a prokinetic treatment for gastroparesis.

Mechanism of action

Postoperative ileus (POI) is a major cause of postoperative complications and prolonged hospitalization. Ghrelin, which is the endogenous ligand for the growth hormone secretagogue receptor, has been found to stimulate gastric motility and accelerate gastric emptying. Ulimorelin is a synthetic ghrelin-receptor agonist, and has been shown to improve gastrointestinal transit in rats with POI.
